In FIG. 7, reference numeral 100 denotes a floating body which is always floating on the water surface, one end of which is supported by a support shaft 100a and the other end of which is freely movable, and 101 which is inside the floating body 100 so as to be horizontal when the floating body 100 is floating in still water.

[0008] The operation of the conventional oscillating power generator configured as described above will be described below.

First, one end of the floating body 100 moves up and down due to the progress of the wave. As a result, the track 101 swings.
Due to the swing of the trajectory 101, the moving body 102

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An oscillating power generator according to a first aspect of the present invention includes a hollow container and a plurality of power generating mechanisms disposed inside the hollow container. And
The hollow container is formed in a closed structure, and the power generating mechanism includes a linear track, a moving body that freely moves on the track, and a generator that generates power by moving the moving body. The mechanisms are arranged horizontally so that the direction of the axis of the track of at least one power generation mechanism is different from the direction of the axis of the track of another power generation mechanism.

With this configuration, the following operation is obtained. (1) The hollow container is anchored by an anchor or the like while floating on water, and is swung by waves. By the swing of the hollow container, each of the plurality of power generating mechanisms disposed in the hollow container is swung, and the inclination angle of the orbit of each of the power generating mechanisms is oscillated by the swing. When the orbit is inclined, the moving body on the orbit is accelerated downward by the gravity, and reciprocates on the orbit in conjunction with the vibration of the inclination angle of the orbit. When the moving body moves on the orbit, power is generated by the generator. (2) In each of the power generating mechanisms, the axis of each orbit is radially displaced from the vertical center axis in a circumferential direction, so that the vibration direction is like a wind wave in the ocean. Even when the hollow container is rocked by waves having an irregular and complicated shape, stable power generation can always be performed, and the energy of the waves can be converted into electric energy with high efficiency. (3) The power generation mechanism is composed of a track, a moving body moving on the track and a power generator, and has a compact configuration, so that the power generation mechanism can be stacked at a high density, and a large number of power generation mechanisms are arranged in a hollow container. As a result, it is possible to effectively utilize the volume and obtain a high power generation amount per hollow container.

Here, the movement of the moving body is a linear movement,
The generator is, for example, a rotary generator (shunt generator, series generator, multiple generator) that is driven to rotate via a movement direction conversion mechanism that converts the linear movement of the moving body into a rotational movement and transmits the movement. A DC generator or an AC generator composed of a winding generator or the like is used. At this time, the movement direction conversion mechanism is equipped with a gearbox,
It is preferable that the linear motion of the moving body be increased to be converted into a rotational motion. Further, as a generator, a permanent magnet stator is arranged on one of the moving body and the track,
Alternatively, a linear motor may be used in which a coil is disposed on the other side to constitute a linear motor, and an induced current is generated in the coil by the movement of the moving body to generate power.

The electric energy generated by the generator may be used as a power source for a marker light, a fish-collecting light, or the like, which is integrally mounted on the hollow container, or may be transmitted by a power transmission cable.

Each of the power generating mechanisms is disposed horizontally so that the direction of the axis of the track of at least one of the power generating mechanisms is different from the direction of the axis of the track of the other power generating mechanism. As a method of, for example, may be arranged in a stack so that the axis of each track is radial to the vertical center axis direction connecting the center line of each track, On the other hand, each power generation mechanism may be arranged such that the axis of each track is radial on one horizontal plane. Furthermore, a plurality of power generation mechanism assemblies in which the power generation mechanisms are disposed such that the axis of each track is radial on one horizontal plane with respect to the vertical center axis may be arranged in a plurality of stages. In addition, the way of disposing each power generation mechanism is not limited to the one radially arranged with respect to one axis. For example, the power generation mechanism is annularly arranged so that the track of each power generation mechanism forms each side of a polygon. May be. However, in order to make the oscillating generator compact, it is preferable that the respective power generating mechanisms are arranged in a stack so that the axis of each track is radial with respect to the vertical center axis.

Further, the hollow container may be formed horizontally long, and a plurality of groups of power generating mechanisms radially arranged in the central axis direction may be arranged in parallel. Thus, high-output electric energy can be generated and can be effectively used as a breakwater.

A weight is mounted on the moving body so that a large kinetic energy is generated in the moving body even when the inclination of the trajectory due to waves is small. As a result, a large driving force for driving the generator can be obtained, and the speed increase ratio can be increased to obtain a large amount of power generation.

The length of the trajectory is such that when the moving body moves on the trajectory due to the vibration of waves, the moving body reaches the lower end of the trajectory at the time when the positive or negative of the inclination angle of the trajectory changes. It is preferable that the length be sufficiently longer than the length. Also,
At the end of the track, a stopper made of an elastic body such as synthetic rubber or a spring for stopping the movement of the moving body is provided. Thereby, the reciprocation of the moving body can be smoothed by the repulsive force of the stopper.

According to a second aspect of the present invention, there is provided the rocking type power generating apparatus according to the first aspect, wherein each power generating mechanism has a vertical center line of the track so that the direction of the axis of each track is different. Are arranged radially in a plan view.

According to this configuration, the following operation can be obtained in addition to the operation of the first aspect. (1) The swing generator can be made compact. (2) Because the space for the rocking generator on the water is small, it does not hinder the vessels navigating on the water. Also, such as the power generator for the light buoy and the generator for the cage of the farm, It can also be used in cases where the power generation device needs to be small.

Here, the center axis can be arbitrarily determined in the hollow container. However, in order to prevent the oscillating power generator from tilting when the oscillating power generator floats on water, Decide so that the center of gravity of the whole power generation device is not biased.

The invention described in claim 3 is the first or second invention.
And a stopper disposed near both ends of the track to stop the movement of the moving body moving on the track.

According to this configuration, the following operation can be obtained in addition to the operation of the first or second aspect. (1) When the moving body accelerates due to the inclination of the trajectory and moves on the trajectory, the kinetic energy of the moving body increases. Although the inclination angle of the orbit oscillates with the vibration of the hollow container, when the sign of the inclination angle of the orbit changes (that is, when the direction of the inclination of the orbit changes), the moving body generates kinetic energy along the orbit axis. If it has, even if the inclination of the orbit changes due to its inertia, the moving body moves upward for a while while decelerating, and then moves downward to the inclination of the orbit. Start exercise. If the frequency of the waves is large and the average period of the vibration of the inclination of the orbit is short, the inclination of the orbit of the orbit with respect to the time from when the direction of inclination of the orbit changes to when the moving object starts moving down the inclination If the average period of the vibration is short, the loss of the kinetic energy of the moving body increases, and a sufficient power generation amount cannot be obtained. Therefore, by stopping the moving body accelerated by the stopper, when the direction of the inclination of the trajectory changes, the moving body can immediately move downward and the kinetic energy loss of the moving body can be reduced. Can be reduced.

At this time, it is preferable that the position of the stopper made of an elastic material such as synthetic rubber or a spring can be freely adjusted by the spectrum of the kinetic energy of the waves or the distribution of the wave height. Because the kinetic energy spectrum and wave height distribution of the wind waves in the ocean change depending on weather and geographical conditions, it is difficult to determine the position where the orbit length is always the optimal value under any conditions. is there.

(2) Since it can be configured with a simple structure, workability during maintenance is improved. (3) Since the structure is simple, even if extremely large swings are applied, such as in a strong wind, it is hard to break down and has excellent durability.

Here, it is preferable that a speed increasing mechanism is provided between the sprocket and the rotating shaft of the generator so that the rotation of the sprocket is increased and transmitted to the generator.
