Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wave power generation system for use in radio buoys, distress signal generation buoys, navigational aids, navigational obstacle markers, and other marine lighting, etc. Regarding equipment.

Conventionally, there have been the following types of power generation devices that generate electricity using the power of waves.

A buoy that is moved up and down by the force of waves, and the vertical motion generated by the buoy is converted into rotational motion using a crank, ratchet wheel, etc., which turns a generator.

A water wheel is turned by moving seawater using the power of waves.

There are some that use the power of waves to rotate windmills using compressed air to generate electricity.

However, these devices are complicated because they have a structure in which a generator is rotated in a fixed direction at a constant speed.

The present invention has been made in view of such conventional drawbacks, and has a structure in which a floating body 7 having buoyancy is attached to the outer upper part of a buoy body 6 in which the upper part of a bottomed cylindrical body 1 is sealed with a lid body 3. A first small gear 12 and a large gear 13 are pivoted on a receiving plate 10 attached to the upper part of a guide frame 9 housed in the buoy main body 6 so as to float on water while maintaining a vertical posture. Axial support 14
An alternating current generator 16 having a second small gear 15 that meshes with the large gear 13 is attached to the shaft, a storage battery 17 having a generator capacity, and a rectifier 18 are installed. A second shaft support 22 on which a third small gear 21 is pivotally mounted is mounted on a bottom plate 20 to which an annular first buffer rubber 11 is attached and attached to the lower part of the guide frame 9.
is attached so as to be adjustable in the vertical direction, and a second annular buffer rubber 24 is attached on the bottom plate 20,
A weight 2 mounted in the guide frame 9 so as to be movable up and down.
6 is supported from below by a spring 27, and a part of an endless chain 28 in which the first pinion 12 and the third pinion 21 are looped is connected to the weight 26, and connected to the alternator 16 through the rectifier 18. A feature is that a pair of power supply terminals 31 and 32 are provided in an electric circuit 30 formed by connecting a storage battery 17.

Examples of the present invention will be described based on the drawings.
Reference numeral 1 denotes a cylindrical body consisting of a cylinder with a bottom, and a lid body 3 is hermetically fixed onto a flange portion 2 formed on the outside of the upper part via an annular seal packing 4 to form a buoy body 6.
An illumination light (not shown) is installed inside the lid 3, and a floating body 7 is attached to the flange 2 provided on the outside of the upper part of the cylinder 1.
Attach and secure.

Reference numeral 9 denotes a guide frame formed by connecting upper, middle, and lower parts by a plurality of connecting frames 8, and is housed in the cylindrical body 1. A receiving plate 10 is attached to the upper part of the guide frame 9, and a first small gear 12 and a large gear 13 are mounted on the receiving plate 10.
An alternating current generator 16 having a second small gear 15 meshing with the large gear 13, a cadmium storage battery 17, and a silicon rectifier 18 are attached.

A third plate is attached to the bottom plate 20 attached to the lower part of the guide frame 9.
A second shaft support 22 having a small gear 21 is mounted so as to be adjustable in the vertical direction with bolts and nuts 23,
A second cushioning rubber 24 is fixed to the upper surface of the bottom plate 20.

Reference numeral 26 denotes a weight mounted vertically movably in the guide frame 9, supported from below by a spring 27, and connected to the first pinion 12 of the first shaft support 14 and the second pinion 26.
The first pinion 12 provided on the shaft support 22 and a third pinion 21 having the same diameter are rotated by an endless chain 28 to interlock with each other. A bolt 19 is attached to a part of the chain 28 that is inserted inside the weight 26.
Fix it with.

To explain the electric circuit 30, the alternating current generator 16 and the cadmium storage battery 17 are connected through the silicon rectifier 18, and the electric circuit 30 further includes power supply terminals 31 and 32 and an indicator light (not shown).
Connect as appropriate.

Note that the storage battery 17 can store a capacity equal to the power generated by the generator.

Next, to explain the operation of this embodiment, when the force of waves acts on the buoy main body 6 floating on the sea by the floating body 7, and the buoy main body 6 is moved up and down by the vertical movement of the sea surface, The vertical inertia of the weight 26 supported by the spring 27 from below is
The elastic force of the spring 27 is further increased, and along with the vertical movement of the weight 26, the endless chain 28 is rotated to the left or right.
Rotates the first shaft support 14 linked to the first shaft support 1
Electric power is generated by rotating the rotor of an alternator 16 at high speed through a second small gear 15 that meshes with a large gear 13 coaxially connected to the alternator 4.

Power generation by the reverse rotation of the alternating current generator 16 is intermittent, and power can be generated even when rotating in either the left or right direction. Further, even if the rotational speed of the alternating current generator 16 changes irregularly or is intermittent, the voltage waveform thereof is rectified by the silicon rectifier 18. Furthermore, since the cadmium storage battery 17 is charged with a wide range of voltage, it can be charged even though the rotational speed of the alternator 16 varies irregularly, and from the power supply terminals 31 and 32 of the electric circuit 30. Normal direct current can be obtained.

When the amount of power generated by the alternating current generator 16 is temporarily "zero," power can be supplied from the storage battery 17, so that the power can be stably supplied.

The present invention has the following effects.

Since the weight attached to the buoy body so that it can move up and down is supported by a spring from below, the inertia of the weight that moves up and down inside the buoy body due to the vertical movement of the waves is further increased. The power generation capacity can be improved by rotating the generator.

Since cushioning rubber is attached to the lower surface of the receiving plate and the upper surface of the bottom plate, which are attached to the upper and lower parts of the guide frame, even if the weight moves up and down significantly, the shock caused by the weight is absorbed by the cushioning rubber. , it is possible to prevent damage to the device.

Since the floating body is attached to the upper part of the outside of the cylinder,
The buoy body can float on the sea surface while maintaining its vertical position, and since the buoy body is sealed with a bottomed cylindrical body and a lid body, seawater does not seep inside, making it durable. It has a sexual nature.

Since an alternating current generator and a storage battery having the capacity of the generator are combined, even if the amount of power generation temporarily becomes zero, by supplying current from the storage battery, stable power supply can be achieved.
