Description

The present invention relates to a wave power generation device that has a floating body that can move up and down, is installed mainly near the sea surface, and uses the energy generated by the vertical movement of the floating body to generate power. The present invention relates to a wave power generation device that can be floated in water, can be installed in multiple connections, is easy to install and remove, and can be freely applied according to the location and environment.

It has a column moored in the water with its axial direction vertical, and a float arranged in a state of being able to move up and down along the column, and generates electricity by utilizing energy when the float moves up and down due to waves. Various wave power generators have been proposed (see Patent Document 1, for example).

This pile mooring method can moor a wave power generator in a relatively shallow water area, but in a relatively deep water area, the strut becomes too long and the installation cost of the wave power generator increases. Therefore, in relatively deep waters, mooring is performed by a single-rope tension mooring method in which the anchor submerged on the seabed and the lower end of the strut are connected with a mooring rope.

Therefore, in Japanese Patent Application Laid-Open No. 2016-033346 (see Patent Document 2), a wave power generation device that can improve power generation efficiency by a structure that stabilizes the attitude of the wave power generation device and can be miniaturized is provided. A wave power generation device having a floating body that moves up and down due to waves, a support that is moored in water, and a power generation mechanism that generates power using the relative motion of the floating body and the support, It has a float that floats on the water surface and a rod portion that extends downward from the float and is in an upright state, the support is arranged close to the rod portion, and the rod portion moves up and down with respect to the support. A wave power generation device in which a power generation mechanism generates power has been proposed.

Hereinafter, the wave power generation device of the present invention will be described based on the embodiment shown in the drawings.

As shown in FIGS. 1 and 3, the wave power generation device 11 of the present invention includes a power generation device section 21 having a floating body 31 capable of moving up and down under the force of waves, and upper and lower portions of the power generation device section 21. , and a set of connecting horizontal iron poles 61 extending in the same horizontal direction, and as shown in FIG. The floating body 31 of the power generator unit 21 receives the power of the waves and moves up and down by installing it floating on the ocean or near the surface of the sea as a wave power generation device, thereby efficiently generating power. It is a thing.

As shown in the drawing, the power generating device section 21 has a frame body 22 made of a rectangular parallelepiped or a cube. The frame 22 further has a hollow interior 22a, and a floating body 31 is provided in the hollow interior 22a so as to be able to move up and down under the force of waves. Further, an energy transmission iron pole 32 projecting upward is provided from the upper surface 31a of the floating body 31, and in conjunction with the vertical movement of the floating body 31, the energy transmission utility pole 32 also moves up and down. It is possible to do Further, the energy transmission utility pole 32 is mechanically connected to a power generation chamber 41 provided on the upper surface 22b of the frame 22 so that the energy transmission utility pole 32 can generate electricity by vertical movement.

With such a configuration, when the wave power generation device 11 is installed floating on the ocean or near the surface of the sea, the frame 22 has a frame shape to minimize the portion where waves collide. In addition, the floating body 31 provided in the hollow inside 22a of the frame 22 can be relatively moved by the wave with respect to the frame 22. The energy transmission utility pole 32 projecting upward from the upper surface 31a of the floating body 31 moves up and down in conjunction with the floating body 31. As a result, very efficient power generation can be achieved in the power generation chamber 41 which is connected so that power can be generated by the vertical movement of the energy transmission utility pole 32 .

It should be noted that the energy transmission utility pole 32 and the power generation chamber 41 should be able to exhibit comparable power generation efficiency when the energy transmission utility pole 32 moves upward and downward. For example, by combining a plurality of pulleys, the turbine (not shown) provided in the power generation chamber 41 can be rotated in a fixed direction regardless of the direction in which the energy transmission utility pole 32 moves vertically. You may do so.
Then, as shown in FIG. 5 or 6, which will be described later, when a group of wave power generation devices is constructed, the power generation room 41 of each wave power generation device 11 can be sent to the central power collection center. good.

In addition, in the hollow interior 22a of the frame body 22, a pair of floating body anti-swaying iron poles 23 erected through the floating body 31 are installed on the left and right sides of the energy transmission utility pole 32. It is

By adopting such a configuration, it is possible to suppress rolling in the hollow interior 22a of the frame body 22 when the floating body 31 receives the force of waves from the side surface, and the power generating device section 21 damage can be prevented. In addition, the pair of floating body anti-rolling iron poles 23 also play the role of guide rails for the vertical movement of the floating body 31, so that when the floating body 31 receives the force of waves, the floating body 31 can move smoothly. It is designed so that it can move up and down easily and efficiently.

In addition, the frame 22 includes a pair of upper horizontal iron poles 61a extending in a predetermined direction from a pair of upper two sides of the four sides that constitute the upper surface 22b of the frame 22, and a pair of upper horizontal iron columns 61a. A pair of lower horizontal iron poles 61b extending in the same direction as the pair of upper horizontal iron poles 61a from a pair of lower two sides corresponding to the pair of upper two sides of the four sides forming the lower surface 22c. A set of connecting horizontal iron poles 61 is provided, and the plurality of wave power generators 11 can be connected to each other via the set of connecting horizontal iron poles 61 .

With such a configuration, a group of wave power generators can be constructed as shown in FIG. 5 or FIG. 6 which will be described later.

Further, the frame 22 has an air buoyancy box 51 on the lower side of the frame 22. The air buoyancy box 51 can be filled with water. By adjusting the amount, the ratio of water and air in the air buoyancy box 51 can be used to adjust the buoyancy.

With such a configuration, the wave power generation device 11 of the present invention does not need to be fixed to the seabed ground as seen in the conventional technology, and can be installed stably floating on any sea or near the sea surface at all times. Therefore, the wave power generation device 11 of the present invention can be applied regardless of the installation location and installation environment.

A stopper (not shown) may be provided in the upper portion of the hollow interior 22a of the frame 22 to prevent the floating body 31 from rising vigorously, assuming a sudden surge of high waves. The stopper may be provided with a cushioning material (not shown) such as a spring to reduce the load on the floating body 31 .

Next, application examples of the wave power generation device 11 of the present invention are shown below.
First, in the wave power generation device 11 of the present invention, the floating body 31 is composed of a box-shaped floating body main body 31b as shown in FIG. An energy transmission utility pole 32 protrudes from the end. In addition, the floating body body 31b is filled with water from the bottom 31d of the hollow interior 31c to the middle position in the height direction of the floating body body 31b, so that the hollow interior 31c of the floating body body 31b is lowered. and a gravity water section 33 and an air buoyancy section 34 above.

With such a configuration, when the waves rise, the floating body 31 moves upward in conjunction with the rising of the waves due to the buoyancy of the air buoyancy part 34 of the floating body main body 31b, and the waves descend. At times, the gravity of the gravity water portion 33 of the floating body body 31 allows the floating body body 31 to move downward in conjunction with the descent of the waves.

Examples of applicable dimensions of the floating body 31 in the wave power generation device 11 of the present invention are shown below.
In the wave power generation device 11 of the present invention, the floating body 31 has a three-dimensional shape with a height of 6 m, a width of 10 m, and a depth of 10 m. 3 m, and the air buoyancy portion 34 is also 3 m.
With such a configuration, the air buoyancy portion 34 can exert a buoyant force of 300t, and the gravity water portion 33 can exert a gravity force of 300t.
At this time, assuming that a wave with a wave height of 3 m rushes once every 10 seconds, the amount of energy per unit of the wave power generation device 11 of the present invention is 300 t × 6 (once every 10 seconds) × 2 (vertical direction )=3600t.

In the wave power generation device 11 of the present invention, a plurality of wave power generation devices 11 can be continuously and integrally connected via the set of connecting horizontal iron poles 61 as shown in FIG. It can be a group of wave power generators 100 to which arbitrary wave power generators 11 are connected.
As shown in the figure, the floating body 31 may be substantially square when viewed from the plane side, or may be substantially rectangular with arbitrary dimensions.

By adopting such a configuration, the group of wave power generation devices 100 are integrally connected to form a strong assembly, and vertical movement caused by waves can be eliminated. Each of the wave power generators 11 constituting the wave power generator 11 receives the force of the waves moving in slightly different directions, and the floating bodies 31 of each wave power generator 11 are connected to the group of wave power generators. Relative to 100, it can be moved up and down almost 100%. Therefore, the constantly changing kinetic energy of each wave can be efficiently converted into energy for power generation, and power can be generated very efficiently.

In addition, as shown in FIG. 6, the wave power generation device 11 connects a plurality of wave power generation devices 11 continuously and integrally in large numbers via the set of connecting horizontal iron poles 61. Thus, a group of wave power generators 110 consisting of a large number of wave power generators 11 can be formed.

By adopting such a configuration, the group of wave power generation devices 110 are integrally connected to form an extremely strong aggregate, which can eliminate vertical movement caused by waves and easily generate a huge amount of power. It goes without saying that it can be applied from small-scale power generation facilities for individuals and small and medium-sized enterprises to ultra-large-scale power generation facilities for national and global scales.
