Description

The present invention relates to electrical conversion using wave power, wind power and sunlight on the sea, and can realize electrical conversion with an apparatus composed of an integrated system of complex natural energy. In addition, inexpensive power can be provided.

The main uses of natural energy are solar power generation, wind power generation, and wave power generation. Solar power and wind power are already in practical use. However, solar power generation has a high-cost problem of a solar cell panel. In addition to high cost, wind power generation has problems such as a specific installation location and a large site area.

Wave power generation has not yet been put into full-scale practical use, although it is an enormous and high-density energy source. Various types of wave power generation have been proposed, and most of them use the up and down movement of large waves to create a flow of air or water, collect the flow by a duct, and rotate the turbine.

However, since the wave power generation apparatus using fluid cannot be converted into kinetic energy of high-pressure fluid, a system that is large to some extent is required to increase the amount of power generation, and the equipment becomes large and not economical.

In order to realize an efficient wave power generation device, a gyro wave power generation device has been proposed in which shaking of a floating body at sea is received by a control moment gyro and electric power is generated using the energy. However, this power generation method has a drawback that it is structurally complex and expensive.

As such literature materials, the following are known.
JP-A-6-280240, Japanese Patent Laid-Open No. 5-164036 JP 2005-207332 A International Publication WO 02/077369 A1

Accordingly, it is an object of the present invention to provide a low-cost electric power by electrically converting a plurality of natural energies, which is a problem of the prior art, with an integrated system. Another object is to provide a device that can be applied in a wide field, has good convenience, and can contribute to landscapes and fisheries.

In the present invention, one end of a wing whose solar cell is arranged on the upper surface via a rotating shaft is connected to the base body, and the other end can be swung up and down. Oscillation amplifying means for amplifying the vertical movement of the wing by correlating wind force with the wave of the sea surface by the wing, and the movable wing connected to the piston of the fluid pressurizing pump and one end of the oscillating control device, respectively. The provided support pipe includes a fluid pressurizing unit including a fluid pressurization pump cylinder including a fluid circulation system and a fluid pressurization unit connected to the other end of the oscillation control device, and a pressurized fluid from the cylinder circulation system. The first power generation means for generating power by rotating the rotating shaft of the generator to be driven by rotating the rotating shaft of the actuating device, and the second for generating power from sunlight by a solar cell disposed on the upper surface of the movable blade. An apparatus is constituted by the power generation means.

There is an advantage that wave power, wind power, and sunlight, which are enormous marine energy, can be efficiently converted into electric power by an integrated device, enabling weight reduction and low cost of electric power. Moreover, it is applicable also to the mobile body (ship) on the sea. And in global environmental conservation, it is also effective in preventing global warming.

In conventional electrical conversion of wave energy by a float such as a cylindrical or box shape, if the float is floated on a wave, the float will move up and down due to changes in the wave irregularities, but the vertical movement due to wind force will not occur Only the vertical movement caused by wave force is converted into electricity. In the movable wing of the present invention, a significant difference from the conventional float is that a flat wing projects between the waves to form a wind trap, and the wings are lifted by wind force to increase the drop between the wave irregularities. In other words, the swinging motion of the movable blade can be amplified.

When the movable wing is on the convex part of the wave moving in the direction perpendicular to the long side, the surface of the movable wing protrudes between the convex part of the next wave, and a wind trap is formed here. The bottom of the concave portion between the waves is pushed down by the wind pressure while turning around and moving up the movable blade. Then, when the movable blade moves to the concave portion of the wind reservoir, the bottom of the concave portion is lowered. In this case, the head can be increased by the amount correlated with the wind pressure compared to the head between the irregularities of the surrounding waves.

Similarly, even in the case of a wave that is parallel to the long side of the movable blade and that is perpendicular to the base, wind force is applied between the waves and wind pressure is applied to the dent of the wave, thereby simultaneously pushing up the movable blade from below. The bottom of the wave can be pushed down.

Also, as the movable side, one end is connected to the mother body via a rotating shaft, and the other end is movable up and down, and a movable blade is floated on the sea surface. One end of each swing control device is connected, and on the other hand, as a fixed side, a support tube provided on the mother body includes a fluid pressurizing pump cylinder including a fluid circulation system and the other end of the swing control device. Are connected to each other, the swinging motion of the movable blade can pressurize the fluid to a high pressure by the pumping action of the swinging by the pump configuration of the fixed side and the movable side.

In addition, the swing control device normally lowers the inertial moment of the ascending motion quickly when the movable blade changes from the ascending stroke to the descending stroke, and lowers the movable blade to the next ascending process (pressurization of fluid). Since it is possible to move, it is convenient for a moving body such as a ship whose mother side is fast, for example, when the wave unevenness is fast, for example, when a small wave or wind is strong on the sea surface.

In addition, a system including a pump and a movable blade including a circulation system is configured by a system that is linked to a plurality of systems, and the operating device is rotated by connecting the operating device and the rotating shaft of the generator. High power can be obtained efficiently even with a small size.

In addition, the solar cell provided on the upper surface of the movable blade can electrically convert the combined energy of sunlight, wave power, and wind power with an integrated system.

In addition, as provided by airplane wings, the movable wings are easy to adopt a telescopic mechanism and folding mechanism because of the structure, so the movable wings can be changed according to the sea surface conditions such as high waves during typhoons and sea surface swells. Stable power can be obtained.

In this way, regardless of the scale of the device, it is possible to generate power from a large amount of natural energy such as sunlight, wave power, and wind power using an integrated system, and it can be used in a wide range of fields such as land, marine structures, and hulls. can do. In addition, the purpose of increasing the amount of electrical conversion and obtaining low-cost and low-cost power has been realized in a compact manner with a minimum number of parts.

The movable wing 3 is made of a lightweight resin material and has a flat cross section with a large gap inside so that it can easily withstand the shock of the wave due to the drop between the wave irregularities. The other end of the wing 3 is manufactured with an arc like a bow.

Although the movable wing 3 is not shown in the drawing, an electric telescopic mechanism and a folding mechanism around the center are provided on the mother side, so that the movable wing 3 is operated in accordance with the state of the sea surface such as a high wave at the time of a typhoon and a sea surface swell. Yes.

Inside the movable wing 3 on the side connected to the base body 2, one end of a piston 8 and a swing control device 10 constituting a fluid pressurizing pump are movably connected. Further, the head of the cylinder 16 of the fluid pressurizing pump to which the fluid inflow and outflow circulation pipes are attached and the other end of the swing control device 10 are connected to the front end of the support tube 15 protruding from the mother body 2. Is provided.

Inflow and outflow circulation pipes attached to the head of the cylinder 16 are arranged inside the holding pipe support 15 and connected to the high-pressure fluid 40 and low-pressure fluid 50 pipes via check valves 20 and 22, respectively. The fluid in which the material suitable for the purpose, such as air, water, and silicon oil, is circulated is circulated.

The swing control device 10 can moderately push down the movable wing 3 and limit the swing motion range as a function, and a metal spring or an air spring, a magnet, etc. are adopted, and the device is configured as necessary. A single or a plurality of swing control devices are provided.

The portions where the support tubes 15 are inserted into the movable wings 3 are joined in a sealed manner with a flexible material such as a rubber-based material having a waterproof effect in a bellows shape so that the direction of movement can be freely made. It is provided at the upper part of the rotating shaft 7 or at an intersecting position so as to prevent troubles such as friction.

It is heading toward the movable wing 3 in this order.

When the movable wing 3 is on the wave projection 5a, a wind pool is created in the wave gap 5b by the overhang of the surface of the movable wing 3 so that the wind force wraps around, so that the lift acts on the movable wing 3 by the wind pressure and pushes up from below. The bottom of the wave gap 5b is pushed down.

Next, when the movable blade 3 moves to the wave 5b, since the depth 5b is deeper than the normal 5d depth, the movable blade 3 descends considerably and then rises in the next 5c. Thus, one swinging process is completed. Thus, the stroke distance of the swing can be amplified by applying the wind force between the waves.
