Abstract
The invention relates to a marine all-round light, in particular to the marine all-round light capable of eliminating a blind area, and belongs to the technical field of marine all-round lights. The marine all-round light capable of eliminating the blind area is characterized in that a cylindrical lens (1) is fixedly arranged in each of the horizontal and vertical directions of a connecting line of the center of the all-round light and a mast; the light of the all-round light is refracted by the cylindrical lenses (1), and the refracted light covers the blind area generated by blocking of the mast. The blind area of the angle of the all-round light is 0, and meanwhile, any parallel blind areas do not exist; the marine all-round light is simple in structure and convenient to construct, and the construction cost is reduced relative to a semi-all-round light; a signal light does not need to be far away from a mast body so as to be convenient to replace and maintain, and the security of sailors is improved.
Description
Technical field
The present invention relates to a kind of all-round light peculiar to vessel, particularly relate to a kind of all-round light peculiar to vessel of dead zone-eliminating, belong to all-round light technical field peculiar to vessel.
Background technology
According to the requirement of International Regulations for Preventing Collisions at Sea and Ge great classification society, the blind area angle summation that the ring signal lamp of boats and ships is blocked by all kinds of barriers such as mast body structures, must not be greater than 6 degree of angles.But in view of the structure of mast body itself is often more complicated, the angle summation of all-round light crested is easy to just more than 6 °.Fig. 1 is exactly the mast body structure of certain conventional freighter.
Covering the requirement of blind area angle in order to meet all-round light, having a kind of scheme to be exactly allow all-round light from mast body structure a little further at present as far as possible, making blind area angle be less than 6 degree of angles.But the effect of sea going boats and ships due to main frame and the impact of stormy waves, vibrate very severe, and signal lamp is generally all placed in boats and ships extreme higher position, if all-round light arrange to leave mast body excessively far away, vibration can be very violent, and for light fixture crewman replacing and safeguard can be very dangerous.
Cover the requirement of blind area angle to meet all-round light, also have a kind of scheme to use two cover lamp exactly, arrange two cover lamp in port and starboard direction or stem direction, these two lamps respectively utilize its light-emitting zone of 180 ° to reach the overall requirement meeting 360 °.But can cost be increased like this, and in actual use, two lamps are difficult to the all-round light of fully integrated one-tenth one 360 °, the vision dead zone that existence one section is parallel therebetween.
Object of the present invention, exactly in order to solve the shortcoming of aforesaid operations present situation, under the prerequisite of a use all-round light, meets the requirement that all-round light covers blind area angle.
Summary of the invention
The object of the invention is, under the prerequisite using a set of all-round light, to meet the requirement that all-round light covers blind area angle.
The present invention takes following technical scheme:
An all-round light peculiar to vessel for dead zone-eliminating, the level of all-round light center and the mast line of centres is vertical is above respectively fixedly installed a cylindrical lens 1, and all-round light light reflects through described cylindrical lens 1, and refracted ray covers because mast blocks the blind area of generation.
The present invention utilizes air different with the density of lens, and make light through after lens, the direction of propagation, on the direction of former straightline propagation, deviation occurs, thus makes light enter region, blind area after mast body column originally, thus reaches the object of dead zone-eliminating.
Further, described cylindrical lens 1 is fixed on mast by each pair of bolts 3 up and down.
Further, the diameter of described cylindrical lens 1 is greater than the diameter of mast.
Further, described mast is radar mast 2.
Beneficial effect of the present invention is:
1) the present invention is while 0 realizing all-round light angle blind area, also achieves any parallel blind area do not existed as half all-round light;
2) structure is simple, easy construction, relative half all-round light, saves construction cost;
3) signal lamp can be made away from mast body, thus replacing and the maintenance of light fixture need not to be convenient to, to improve the security of crewman.
Accompanying drawing explanation
Fig. 1 is the mast body structure schematic diagram of conventional freighter in prior art.
Fig. 2 is cylindrical lens top view layout.
Fig. 3 is that cylindrical lens master looks layout drawing.
Fig. 4 is the schematic diagram that lamp mast causes blind area to produce.
Fig. 5 is the principle schematic that blind area of the present invention is eliminated.
In figure, 1. cylindrical lens, 2. radar mast, 3. bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 2-Fig. 3, the present invention utilizes the refraction principle of light, and when namely light injects the different medium of another kind of density from a kind of medium, the direction of propagation can change.The present invention mainly comprises cylindrical lens 2, and fixing fitting is some.Cylindrical lens is corresponding with signal lamp, is separately fixed at the two ends of mast body column, sees Fig. 3.
The present invention utilizes air different with the density of lens, and make light through after lens, the direction of propagation, on the direction of former straightline propagation, deviation occurs, thus makes light enter region, blind area after mast body column originally, thus reaches the object of dead zone-eliminating.Ask for an interview the schematic diagram of Fig. 4-Fig. 5.
The present invention is while 0 realizing all-round light angle blind area, also achieves and there is not any parallel blind area; Structure is simple, easy construction, relative half all-round light, saves construction cost; Signal lamp can be made away from mast body, thus replacing and the maintenance of light fixture need not to be convenient to, to improve the security of crewman.
Claims (4)
1. an all-round light peculiar to vessel for dead zone-eliminating, is characterized in that:
The level of all-round light center and the mast line of centres is vertical is above respectively fixedly installed a cylindrical lens (1), and all-round light light is through described cylindrical lens (1) refraction, and refracted ray covers because mast blocks the blind area of generation.
