Description

FLOATING WATERWHEEL SERVING PRIMARILY AS A MULTIFUNCTIONAL ENERGY GENERATOR

Technical Field

The invention is from the field of energy, production of electricity, production of heat and drive of hydraulic and pneumatic machines and appliances. It relates to the use of flowing water in larger streams, rivers and large watercourses to propel not only electric generators but also hydraulic and pneumatic appliances.

Background Art

Water energy currently ranks among the most frequently used energy sources. It is used primarily in large hydroelectric power plants that are dependent on large water reservoirs. In most cases, they include solid structures located in suitable locations where it is possible to benefit from natural conditions or plants that use artificial slopes, for instance pumping electric power plants. Their construction often requires profound interventions in the surrounding landscape that irreversibly change its character, which may be unsuitable from the viewpoint of ecology.

Most of the said hydroelectric power plants use water turbines as aggregates to propel electric current generators. Currently, the most frequently used are four basic types of water turbines - namely Banki, Pelton, Francis and Kaplan turbines - or their innovated and improved construction designs (e.g. spiral, box and rectilinear flow designs).

Increasingly frequent are also small hydroelectric power plants that may be built in a wide range of locations because of their minimum environmental impact. There have been a number of inventions and applied models pertaining to small hydroelectric power plants that use a variety of screw rotors placed in channels, chambers and ducts. In the Czech Republic, it is the applied model registered under CZ 17561 U1 ; in Germany it is registered under DE 41 39 134, DE 195 07149, DE 103 48 533 and in the United States under US 2004027020. Also, a published patent application CZ 1990-4806 relates to floating hydroelectric power plant using a screw rotor that is placed on a vessel anchored to a sluice. Another floating electric power plant that in certain aspects resembles the present invention is a Czech applied model registered under CZ16778 U1 that uses two cylinders on floats interconnected by a circulating conveyer with blades attached. The conveyer's movement is subsequently transferred to an electric current generator. The author of this applied model views the functioning model as a relatively large appliance with dimensions of 50m x 8m whose blades are 3m in both height and width; however, he fails to specify the appliance's power output.

An applied model registered under CZ9723 U1 envisages the use of a blade wheel that is immersed up to its blades into the stream, which has been diverted into a specified channel; the wheel's kinetic energy is transferred via axle to a gearbox and an electric current generator.

All abovementioned solutions require either more or less profound adjustments to the watercourse or a sufficient slope. None of the described solutions is based on the concept of a hollow waterwheel that accommodates the mechanism that propels the generator.

Disclosure of Invention

The said deficiencies of the previous state of art are eliminated by the floating waterwheel serving primarily as a multifunctional energy generator that consists of a hollow waterwheel with anchor and an engine room. The gist of the invention is that the waterwheel consists of a cylinder covered on both sides; on the outer perimeter it is equipped with a set of blades and on the inner perimeter it is equipped with at least one inner cogged ring. The waterwheel rotates on a central axle resting on a pair of bearings fixed to anchor via arms or a frame. The central axle carries at least two revolving suspensions that support a rotating shaft with at least one cogged pinion whose cogs fit into the inner cogged ring that mechanically transmits the torque, either directly or via a gearbox to at least one generator; the produced energy is conducted into the engine room equipped with control gear, security mechanism, communication apparatus and a meter of produced energy.

The generator may take on any of the three basic forms: electric current generator, hydro- generator or pneumatic generator. Any other than electric energy produced and conducted into the engine room is transmitted through a medium distributor and used directly and/or transformed into electric energy by the means of propelling the engine whose mechanic energy subsequently propels the electric current generator. For the purpose of immersion regulation, an oil tank may be installed inside the waterwheel.

The drifting of at least one floating waterwheel with the water current may be prevented by the means of mounting its arms to anchor that is fixed to a bridge suspension, a bank suspension, a seashore suspension or a pontoon. The drifting of at least one floating waterwheel with the water current may also be prevented by the means of attaching the pair bearings of at least one waterwheel to anchor that is fixed to a frame with at least one float.

Examples of invention embodiments

EXAMPLE 1

FLOATING WATERWHEEL AS A MECHANICAL ELECTRIC ENERGY GENERATOR

The floating waterwheel as a mechanical electric energy generator with direct drive of electric energy generator encased in the waterwheel (see Figures 1 and 2) consists of a hollow waterwheel 1 and an engine room 3. The hollow waterwheel 1 is formed by a cylinder 4 that is closed by lids on both ends 5 and equipped with a set of blades 6 on its outer perimeter. The hollow waterwheel 1 accommodates a hollow central axle 7 that runs through its axis and rests on end bearings 8 attached to arms 9. Inside the waterwheel 1, the central axle 7 accommodates a pair of revolving suspensions 10 that support a rotating shaft V\_ with cogged pinions 12 on its ends whose cogs engage inner cogged rings 13 mounted to the cylinder's mantle 4. The centre of the shaft V\_ runs through a frontal gearbox 14 whose outputs are connected via connectors (not shown on drawings) to a pair of electric current generators 15. The produced electric energy is conducted to an electric switchboard 29 in the engine room 3. The engine room 3 is equipped with control gear 30, security mechanism 3J_, communication apparatus (GSM ports - 32), a meter of produced energy 33_ and outputs of the medium distributor 34. The waterwheel 1 may be connected to the engine room 3 via anchor (not shown on Figures 1 and 2) or the engine room 3 may be located on the structure (e.g. a pontoon) that directly supports the waterwheel λ_.

The water current revolves the anchored floating waterwheel 1 while its construction is resistant to all potentially drifting objects (e.g. driftwood, ice, etc.). The revolving waterwheel 1 with blades 6 transmits the current's power through the inner cogged ring

13, the pinion 12 and the shaft V\_ onto the gearbox 14 that propels the electric current generator 15. The produced electric energy is conducted via conductors 1(3 placed inside the hollow central axle 7 and the arm 9 into the electric switchboard 29 in the engine room 3 located on the bank or on the pontoon.

EXAMPLE 2

FLOATING WATERWHEEL AS A MULTIFUNCTIONAL GENERATOR - AN ELECTRIC

ENERGY GENERATOR AND A HYDRAULIC GENERATOR

Figures 3 and 4 illustrate the floating waterwheel as a multifunctional generator - an electric energy generator and a hydraulic generator; the hydraulic generator is encased in the waterwheel while the hydraulic motor and the electric current generator propelled by it are both located in the engine room.

It consists of a hollow waterwheel 1 and an engine room 3. The hollow waterwheel 1 is formed by a cylinder 4 that is closed by lids on both ends 5 and equipped with a set of blades 6 on its outer perimeter. The hollow waterwheel 1 accommodates a hollow central axle 7 that runs through its axis and rests on end bearings 8 attached to arms 9. Inside the waterwheel 1, the central axle 7 accommodates a pair of revolving suspensions 10 that support a rotating shaft V\_ with cogged pinions 12 on its ends whose cogs engage inner cogged rings 1_3 mounted to the cylinder's mantle 4. The cogged pinions 12 engage a pair of hydraulic energy generators 15. An alternative solution allows for placing a frontal gearbox 14 before hydraulic generators like in Example 1. The generators 15 supply the produced energy into the engine room 3 via piping 1_6. Here, the produced energy is distributed by the medium distributor 34 into energy for direct consumption and energy to propel a rotating hydraulic motor 1_8 that subsequently propels an electric current generator ^9_. The produced electric energy is conducted to an electric switchboard 29. The engine room 3 is equipped with control gear 30, security mechanism 3J_, communication apparatus (GSM ports - 32) and a meter of produced energy 33. The engine room 3 also accommodates a hydraulic tank 35 and a filter 36.

Inside, the waterwheel 1 accommodates a hydraulic oil tank X7_ to regulate immersion of the waterwheel λ_. The waterwheel 1 may be connected to the engine room 3 via anchor (not shown on Figures 3 and 4) or the engine room 3 may be located on the structure (e.g. a pontoon) that directly supports the waterwheel 1.

The water current revolves the anchored floating waterwheel 1 while its construction is resistant to all potentially drifting objects (e.g. driftwood, ice, etc.). The revolving waterwheel 1 with blades 6 transmits the current's power through the inner cogged ring 13, the pinion 12 onto the shaft V\_ that propels the hydraulic generator 15. The produced energy in the form of compressed hydraulic medium 1_6 is conducted via the hollow central axle 7 and the arm 9 into the engine room 3 located on the bank or on the pontoon.

In the engine room 3, the entire energy or its part is used to propel the hydraulic motor 18 that propels the electric current generator 19. In the case of only partial use of produced energy, the remaining energy is branched off via the medium distributor 34 and consumed directly to propel various machines and appliances using hydraulic motors (e.g. cableways, power saws, mills, dredgers, etc.).

During the launch phase of the multifunctional generator, the medium distributor 34 is switched to the "weir" position, ensuring that the hydraulic medium returns to the tank 35. Once the required amount of revolutions is achieved, the medium distributor 34 switches to the "work" position and the pair of generators 15 begins to press the hydraulic medium into the hydraulic motor 18 that is connected to the electric current generator ^9_ or other attached appliance. The output regulation may be performed on the hydraulic circuit, in the gearbox 14 - provided it is placed before the generator 15 - or inside the electric current generator 1^. On the hydraulic circuit, regulation is performed via the medium distributor 34, i.e. the microprocessor-operated regulation and relief valve that maintains required constant pressure on the hydraulic motor that propels the attached appliance. In the case of electric energy production, it maintains the generator at constant speed and thus the quality of electric energy output from the generator.

In order to comply with safety regulations pertaining to manipulation with oil near watercourses, the hydraulic medium runs in double piping that conducts the leaked oil back to the oil tank; the leakage is electronically monitored by the central security system.

The service life of the appliance may be enhanced by the waterwheel's hermetic design; in order to eliminate humidity the air inside the waterwheel is replaced by gas that does not cause corrosion of the appliance.

EXAMPLE 3

FLOATING WATERWHEEL AS A MULTIFUNCTIONAL ENERGY GENERATOR - AN ELECTRI C ENERGY GENERATOR AND A PNEUMATIC COMPRESSED AIR GENERATOR

Figures 5 and 6 illustrate the floating waterwheel as a multifunctional generator - an electric energy generator and a pneumatic generator of compressed air; the compressed air generator is encased in the waterwheel while the turbine and the electric current generator propelled by it are both located in the engine room.

It consists of a hollow waterwheel 1 and an engine room 3. The hollow waterwheel 1 is formed by a cylinder 4 that is closed by lids on both ends 5 and equipped with a set of blades 6 on its outer perimeter. The hollow waterwheel 1 accommodates a hollow central axle 7 that runs through its axis and rests on end bearings 8 attached to arms 9. Inside the waterwheel 1, the central axle 7 accommodates a pair of revolving suspensions 10 that support a rotating shaft V\_ with cogged pinions V2 on its ends whose cogs engage inner cogged rings 1_3 mounted to the cylinder's mantle 4. The cogged pinions 12 engage a pair of pneumatic energy generators - compressors 15. An alternative solution allows for placing a frontal gearbox 14 before pneumatic generators like in Example 1. The generators 15 supply the produced energy - i.e. the compressed air - into the engine room 3 via piping 1_6. Here, the produced energy is distributed by the medium distributor 34 into energy for direct consumption and energy to propel a turbine 18 that subsequently propels an electric current generator 19. The produced electric energy is conducted to an electric switchboard 29. The engine room 3 is equipped with control gear 30, security mechanism 3J_, communication apparatus (GSM ports - 32) and a meter of produced energy 33. The engine room 3 also accommodates other parts of the pneumatic circuit, i.e. a medium tank or a receiver 35, a filter or air purifier 36, an intake valve 38 and a safety valve 39.

Inside, the waterwheel 1 may accommodate a hydraulic oil tank X7_ to regulate immersion of the waterwheel λ_. The waterwheel 1 may be connected to the engine room 3 via anchor (not shown on Figures 5 and 6) or the engine room 3 may be located on the structure (e.g. a pontoon) that directly supports the waterwheel λ_.

The water current revolves the anchored floating waterwheel 1 while its construction is resistant to all potentially drifting objects (e.g. driftwood, ice, etc.).

During the launch phase of the multifunctional generator, the medium distributor 34, which is an electromagnetic compressed air outtake valve, is switched to the "circulation" position, ensuring that the medium - air - returns to the receiver 35. Once the required amount of revolutions is achieved, the medium distributor 34 switches to the "work" position and the pair of compressors 15 begins to press air into the receiver 35 and subsequently onto blades of the turbine 1_8 that propels the electric current generator 19. The appliance may also be set to a regime that allows for branching off part of energy produced by the waterwheel via the medium distributor 34 and consuming it directly in order to propel various machines and appliances using pneumatic motors (e.g. cableways, power saws, mills, dredgers, etc.).

The output regulation may be performed on the pneumatic circuit by the medium distributor 34, in the gearbox 14 - provided it forms part of the waterwheel 1 - or inside the electric current generator 19.

The basic advantage of the pneumatic circuit is operation safety as leaked air cannot cause an ecological disaster.
