The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but not by way of limitation.

The first thing to note is that the axle face in the axle mentioned below refers to the plane passing through the axis of the axle. When the opening and closing type water flow device of the present invention is placed in a water stream, the axial surface of the axle parallel to the direction of the water flow is a horizontal axis.

As shown in Figures 1 to 3, a split-type water flow device disclosed in the present invention is placed in a water field in which a water flow exists. The opening and closing water flow device comprises an axle 1 and a plurality of bucket assemblies. The two ends of the axle 1 are respectively fixedly connected with a round box-shaped end plate 2 (the two ends of the axle 1 protrude from the end plate 2), and the axis of the end plate 2 is The axes of the axles 1 coincide.

Each of the bucket assemblies includes: a vane 3, a water flow pressure sensor, a vane rotation state control Controller 9 and vane transition operator.

As shown in FIGS. 1 to 3, the vane 3 is disposed on the axle 1 in the axial direction of the axle 1, and the vane 3 is composed of a plurality of rectangular vane blades 5 of the same shape as shown in FIG. The fins 5 are arranged in a single row, and the feather-shaped blade 5 has a rod 6 along the central axis of the length, and the feather rod 6 is connected to the axle 1. In the present invention, the feather rod 6 is vertically inserted into the axle 1 and passes through the axis of the axle 1, the end of the feather rod 6 projects from the other side of the axle 1, and the end of the feather rod 6 is pierced with an anti-decoupling strip 7. The feather blade 5 is rotatable about the feather shaft 6.

The vane 3 has two states as shown in Figs. 1 and 2, and is restored when the surface of the feather vane 5 coincides with the axial plane of the axle, that is, the state shown in Fig. 1, at which time the vane blade 5 - piece A side by side can cause the water flow to push it to rotate and drive the axle 1 to rotate. In order to effectively block the water to cause the water flow to push it, the edges of the adjacent two pinnate blades 5 are preferably attached but not overlapping, that is, the state shown in Fig. 1, that is, the adjacent two pinnate blades 5 The distance between the feather rods 6 is the width of the feather-like blades 5, and in use, the feather-like blades 5 can be rotated in both the clockwise and counterclockwise directions, so that the feather-like blades 5 are between the vertical state and the restored state. Switch. Of course, the arrangement between the two adjacent feather-like blades 5 is not excluded, that is, a certain gap may be left between the adjacent two feather-like blades 5, but the water blocking effect may not be as close as the edge. . Further, it is also possible to design the edges of the adjacent two fin-shaped blades 5 to overlap in the same direction in this order, but in this case, the feather-like blades 5 can be rotated only in one direction. When the plane of the feather blade 5 is perpendicular to the axial plane of the axle of the bucket 3, that is, the state shown in Fig. 2, the water flow can flow between the feather blades 5, and the plume blade 5 flows against the water. No blocking power.

The water flow pressure sensor is disposed near the one end plate 2, and the water flow pressure sensor is used to instantly sense the water flow pressure of the vane 3 and output the water flow pressure value. The vane transition controller 9 is disposed in the same side end plate 2 of the water flow pressure sensor, and is connected to the water flow pressure sensor, and outputs the vane rotation state command according to the magnitude of the water flow pressure value sensed by the water flow pressure sensor. The vane transition operator is coupled to the vane transition controller 9 and operates the vane 3 to switch between a restored state and a vertical state in accordance with the vane transition command output from the vane transition controller 9.

The vanes 3 of the opening and closing water flow device of the present invention are evenly distributed and arranged in a radial manner On the axle 1, and the vanes 3 are located between the two end plates 2 and shorter than the distance between the two end plates 2. The length of the plurality of vanes 3 may be the same or different. In addition, since all the feather rods 6 need to pass through the axle 1 and pass the axis of the axle 1, twelve feather poles 6 per week (illustrated by taking twelve blades 3 as an example) cannot be in the same horizontal direction of the axle 1 In cross section, when the brace 6 of one of the vanes 5 of one of the vanes 3 passes through the axis of the axle 1, the brace 6 of the vane 5 of the next vane 3 cannot be in the same cross section of the axle 1 While passing through the axle 1 at the same time, it can only be offset through the axle 1, and so on, twelve feather poles 6 are to pass through the axle 1 within the width of the feather blade 5, provided that each feather pole 6 passes through the axle 1 The position is evenly distributed, so the difference between the adjacent two rods 6 (not on the same vane 3) is one-twelfth the width of the feather-like blades. As shown in Fig. 10, if the first feather rod 6 of the first blade 3 is inserted at point A, the second feather rod 6 of the first blade 3 is inserted at point B, and the second wheel is inserted at point C. The first feather rod 6 of the leaf 3, the first feather rod 6 of the third blade 3 is inserted at point D, the first feather rod 6 of the fourth blade 3 is inserted at point E, and the fifth piece is inserted at point F. The first plume 6 of the vane 3 is inserted into the first plume 6 of the sixth vane 3 at point G, the first plume 6 of the seventh vane 3 is inserted at point H... and so on. The X in the figure represents the ratio of the width of the feathered blade to the number of vanes. That is, the feather rods 6 of the respective vanes 3 are sequentially arranged in a wrong position, and cannot be oppositely disposed.

What has been disclosed above is the case where the feather rod 6 passes through the axle 1 . Of course, the arrangement in which the feather rod 6 is rotatably coupled to the axle 1 but does not penetrate the axle 1 is not excluded. At this time, twelve feather poles 6 can be It is disposed on the same cross section of the axle 1, but the portion of the feather rod 6 passing through the axle 1 is shorter than the radius of the axle 1 and cannot pass through the axis of the axle 1. However, in view of the problems of assembly, the force of the brace 6, and the fatigue of the axle material, it is preferable in the present invention to adopt the structure in which the feather rod 6 penetrates the axle 1.

The opening and closing type water flow device of the present invention is horizontally arranged according to the direction of the axle, as shown in Fig. 3. The vane 3 above the horizontal shaft surface 8 is initially set to a vertical state, and the vane 3 below the horizontal shaft surface 8 is initially set to be restored. status. When the opening and closing water flow device of the present invention is placed in the water with water flow, it will rotate under the action of the water flow, and the vanes 3 rotated to the horizontal shaft surface 8 by the vane rotation operator are restored. Switching between the vertical state and the vertical state, so that the vane 3 above the horizontal axial plane 8 is always in a vertical state, and the horizontal axial plane 8 The lower vane 3 is in a restored state. As shown in Fig. 3, the direction of the arrow in Fig. 3 indicates the direction of the water flow, the vane 3 rotates counterclockwise under the action of the water flow, the vane 3 above the horizontal axial surface 8 is in a vertical state, and the vane 3 below the horizontal axial surface 8 To restore the state. When the vane 3 below the horizontal axial plane 8 is rotated to coincide with the water surface axial surface 8 on the right side, it will be switched from the restored state to the vertical state under the manipulation of the vane transition operator, above the horizontal axial plane 8 When the vane rotates to coincide with the horizontal axial plane 8 on the left side, it will be switched from the vertical state to the restored state under the manipulation of the vane transition operator.

Of course, the vanes 3 above the horizontal axial plane 8 can also be initially set to a restored state, and the vanes 3 below the horizontal axial plane 8 are initially set to a vertical state, and are placed on the horizontal axial plane by the vane transition operator. The vane 3 above 8 is always in a restored state, and the vane 3 located below the horizontal axial plane 8 is always in a vertical state, at which time the vane 3 drives the axle 1 to rotate clockwise together under the action of water flow.

The water flow pressure sensor of the vane assembly of the present invention is a long plate-shaped water flow pressure sensing plate 4, and the water flow pressure sensing plate 4 is fixedly disposed on the axle 1 between the vane 3 and one of the end plates 2, and When the vanes 3 of the vane assembly are in a restored state, they lie in the same plane. The water flow pressure sensing plate 4 can adopt a method of providing a pressure sensor on one side, that is, only one side of the water flow pressure sensing plate 4 can sense the water flow pressure. For the case where the vane 3 above the horizontal axial plane 8 shown in Fig. 3 is in a vertical state and the lower vane 3 is in a restored state, the pressure sensor on the water flow pressure sensing plate 4 located below the horizontal axial plane 8 welcomes The water flow can feel the pressure of the water flow. When it rotates to the horizontal axis surface 8 on the right side, the pressure it feels decreases continuously until it is rotated to the horizontal axis surface 8, the pressure is close to zero, when it rotates to When the horizontal axis 8 is above, the induced pressure is also close to zero due to the direction of the pressure sensor facing away from the water flow. Therefore, the vanes 3 need to be arranged in pairs, each pair of vanes 3 being 180 degrees, when the pair of vanes 3 sense the pressure change to a minimum value close to zero pressure as long as the water flow pressure sensing plate 4 senses the pair The vanes 3 are switched between a vertical state and a restored state.

Of course, the water flow pressure sensing plate 4 can also adopt a method of setting the pressure sensor on both sides. At this time, the setting of the vanes 3 does not need to be set in pairs, and can be independently controlled as long as the water flow pressure sensing plate 4 senses close to zero pressure. Minimum value, the vane transition controller 9 output The vane transition command, the vane shift operator operating vane 3 switches between a restored state and a vertical state.

In this embodiment, a ferrule 21 is disposed at one end of the linkage rod 11, and the ferrule 21 is fitted with the feather rod 6 and firmly coupled with the ferrule 21. When the power transmission mechanism receives the blade rotation state command outputted by the vane rotation state controller 9, the push-pull rod 10 is pushed forward and backward (ie, moves along the axis direction of the axle 1), thereby driving the feather blade 5 to turn 90 degrees. , realizes that the vane 3 is switched between the restored state and the vertical state. In addition, in order to realize the simultaneous angular rotation of the plurality of feather vanes 5 constituting the same vane 3 under the driving of the push-pull rod 10, the plurality of interlocking rods 11 are disposed at the same inclination as shown in FIGS. 4 and 5. angle.

One end of the drive link 13 is connected to the power unit 12, and the other end of the drive link 13 is driven. Coupling with one end of the push-pull rod 10, the power unit 12 rotates forward or reverse according to the vane rotation command issued by the vane rotation controller 9 to drive the push-pull rod 10 to move back and forth (moving in the axial direction of the axle 1). . The forward and backward movement of the push-pull rod 10 drives the feather rod 6 to rotate, so that the vane 3 is switched between the restored state and the vertical state, and the power device 12 is more flexible in selection, as long as the driving link 13 can be driven to reciprocate. Into the motor or hydraulic transmission, etc. The power transmission mechanism can also be realized by the structure shown in FIG. 8. As shown in FIG. 8, the power transmission mechanism includes a telescopic mechanism 14 and a push rod 15, and one end of the push rod 15 is hinged with the telescopic mechanism 14 and is telescopic The push-pull motion is carried out by the mechanism 14 , and the other end of the push rod 15 is hinged with the push-pull rod 10 to drive the push-pull rod 10 to move back and forth. The forward and backward movement of the push-pull rod 10 causes the feather rod 6 to rotate, thereby realizing the switching of the vane 3 between the restored state and the vertical state.

The working principle of this embodiment will be described below with reference to the accompanying drawings:

When the opening and closing water flow device of the present invention is placed in the water having the water flow, the vane 3 above the horizontal axial surface 8 is initially set to the vertical state, and the vane 3 below the horizontal axial surface 8 is initially set to the restored state. Due to the action of the water flow, the vane 3 rotates counterclockwise or clockwise, thereby driving the axle 1 to rotate. When the vane 3 is rotated to coincide with the horizontal axial plane 8, the water flow pressure sensing plate 4 senses the water flow pressure to zero pressure. The vane rotation state controller 9 outputs a vane rotation state command, thereby controlling the power device 12 or the telescopic mechanism 14 of the power transmission structure to move, thereby pushing the push-pull rod 10 to move back and forth, thereby driving the feather vane 5 to turn 90 degrees. The vane 3 is realized to switch between a restored state and a vertical state.

Embodiment 2

After the feather rod 6 passes through the second hollow tube 19 and then passes through the axle 1, the power mechanism 17 rotates forward or reverse according to the vane rotation command outputted by the vane transition controller 9 to drive the feather vane 5 to rotate. Thereby the vane is switched between the restored state and the vertical state. The power mechanism 17 in this embodiment adopts a stepping motor, that is, each feather blade 5 is provided with an independent stepping motor, and the feather rod 6 located in the second hollow tube 19 is sleeved on the stepping motor.

Due to the action of the water flow, the vane 3 rotates counterclockwise or clockwise, thereby driving the axle 1 to rotate. When the vane 3 is rotated to coincide with the horizontal axial plane 8, the water flow pressure sensing plate 4 senses that the water flow pressure is close to zero. The minimum value of the pressure causes the vane transition controller 9 to output the vane rotation command, thereby controlling the power mechanism 17 of the power transmission structure to start, thereby driving the feather rod 6 to rotate, and turning the feather vane 5 to 90 degrees. The vanes 3 are switched between a restored state and a vertical state.

There are also two 50,000-kilowatt power units with a total installed capacity of 22.5 million kW, or 22,500 MW. The middle reaches of the Yangtze River are one thousand kilometers long, with an average flow rate of 1 m/s. Tens of thousands of cylinders with a radius of 1 m and a length of 1000 m can be installed in the river. The power generation can exceed that of the Three Gorges Dam hydropower station. Power generation. The water flow velocity in the upper reaches of the Yangtze River reaches 3 m / s, the same The power generation of the device is increased by a factor of ten.

The developable capacity is about 260 million kilowatts, about 11 generations of the Three Gorges Dam hydropower station. Times, if it can achieve half of the effect, it has 5 times the power generation capacity of the Three Gorges Dam hydropower station.

In addition, ocean current energy is even larger, and the theoretical average power of China along the ocean current is 140 million kilowatts. The total flow of the Gulf Stream in the United States has reached 7400 to 93 million cubic meters per second, which is more than 80 times the total amount of all rivers on land. Compared with the rivers in China, it is about 2600 times the flow of the Yangtze River or 57,000 times that of the Yellow River. Researchers at the Woods Hole Ocean Research Institute in the United States point out that the Gulf Stream is driven by wind, the Earth's rotation, and the heat that is moving toward the Arctic, which is equivalent to 2000 times the US's power generation capacity.
