Abstract

PURPOSE:To take out huge amount of electric energy by providing a flabellate duct for converting kinetic energy and a nonreturn valve on a borderline between said flabellate duct and a pressure tank, and combining a generator with output of a hydraulic motor. CONSTITUTION:A pressure tank 20 is provided next to a flabellate duct 10 for converting kinetic energy. A nonreturn valve 30 is provided in a position inside the pressure tank 20 and on a borderline to the flabellate duct 10. A conduit tube 40 is provided down the pressure tank 20 and a closing valve 50 is provided. A hydraulic motor 60 is provided at the open end of the conduit tube 40. A generator 70 is combined with output of the hydraulic motor 60. Upward and downward kinetic energy of waves is converted to percussive intermittent advancing kinetic energy like tidal wave.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates generally to power generators, and more particularly to wave power generators.

In particular, it relates to a generator that converts the vertical kinetic energy of waves into intermittent traveling energy.

[Prior Art] Conventional wave power generators utilize the vertical motion of waves as mechanical energy, and use that mechanical energy to drive a generator.

[Problems to be solved by the invention] As with wind power generation, it is extremely inefficient to use the energy as it is without first converting it. For example, in hydroelectric power generation, large-scale energy cannot be extracted by installing a water wheel in the flow of a river to generate electricity.

Hydroelectric power generation, which is currently used for commercial power generation, first converts water flow energy into hydraulic energy using high-head conduits, and then generates electricity using this huge hydraulic energy.

However, conventional wave power generation does not perform such a primary conversion of energy, but simply uses the vertical motion of the waves as is. Therefore, the energy is small, and extracting huge amounts of energy requires extremely large-scale equipment, making it impractical.

[Means for Solving the Problems] In view of the above problems, the wave power generator according to the present invention has the following features:
The vertical kinetic energy of this wave is converted into shocking intermittent forward kinetic energy similar to a tsunami, this huge impact energy is stored in a tank, and the high-pressure water is used to generate electricity.

Below, a specific configuration of wave power generation according to the present invention will be explained in detail. First, there is a fan-shaped conduit for kinetic energy conversion. Next is the pressure tank.

This pressure tank is provided near a key position of the fan-shaped conduit, and contains air at the top and water at the bottom. And then there is the regurgitation valve. This check valve is provided within the pressure tank at the boundary with the fan-shaped conduit.

Additionally, there is a water pipe. This water conduit is provided below the pressure tank. And there is an on-off valve. This on-off valve is provided in the water pipe described above. Additionally, there is a water pressure motor. This water pressure motor is provided at the open end of the water pipe. Finally, there's the generator. This generator is coupled to the output of the hydraulic motor described above.

[Function] Since the wave power generation according to the present invention has the above configuration, the following effects occur.

That is, the fan-shaped conduits convert the vertical kinetic energy of the waves into intermittent forward kinetic energy, such as a tsunami.

Next, since the pressure tank is provided near a key position of the fan-shaped conduit, the water converted by the fan-shaped conduit enters here. This pressure tank has air at the top and water at the bottom, so the water that enters here compresses the air. A check valve then prevents the backflow.

Further, a water conduit is provided below the pressure tank, in which an on-off valve is located. This on-off valve is closed at the beginning of its operation and is opened after the air has been sufficiently compressed by the water entering from the fan-shaped conduit. Further, a water pressure motor is provided at the open end of the water conduit and is driven by high pressure water discharged therefrom. Finally, the generator
It is coupled to and driven by the output of the water pressure motor mentioned above.

[Embodiment] Below, wave power generation according to the present invention will be explained in detail using an embodiment thereof with reference to the accompanying drawings.

FIG. 1 shows a partially omitted plan sectional view of an embodiment of wave power generation according to the present invention. FIG. 2 shows a side sectional view of the embodiment of FIG. 1.

First, there is a fan-shaped conduit 10 for kinetic energy conversion that is vertically parallel and tapered horizontally. Next, there is the pressure tank 20. This pressure tank 20 is connected to the fan-shaped conduit 1 described above.
It is installed near the point 11 of 0, and has air 21 in the upper part and water 22 in the lower part.

And there is a check valve 30. This backflow valve 3o is provided in the pressure tank 20 at the boundary with the fan-shaped conduit 10, and prevents water in the pressure tank 20 from flowing back into the fan-shaped conduit 1o. This is to prevent

Furthermore, there is a water conduit 40. This water conduit 4o is provided below the pressure tank 20 described above. Then, there is an on-off valve 50. This on-off valve 50 is provided in the water conduit 40 described above. Of course, this on-off valve 50 may be located not only in the middle of the water conduit pipe 4o but also before and after it. Furthermore, there is a hydraulic motor 6o. This water pressure motor 60 is provided at the open end 41 of the water conduit 4o.

Finally, there is power generation 8!70. This generator 7o is connected to the output of the water pressure motor 60 described above.

[Effects of the Invention] Because the wave power generation according to the present invention has the above configuration, the vertical kinetic energy of waves is converted into impulsive intermittent forward kinetic energy like a tsunami, which is stored in a pressure tank and generated at high pressure. The water turned into water and drove a hydraulic motor, which could generate a huge amount of electrical energy.
