Conventionally, practical industrial power generation has been covered by three major power sources: hydro, thermal, and nuclear power. However, the location of hydropower is limited, and thermal power and nuclear power are limited. In the future, problems such as fuel finiteness, danger, and environmental destruction due to carbon dioxide are being considered.

[0004] Under such circumstances, solar power generation, wind power generation, wave power generation, geothermal power generation and the like of natural clean energy have been reviewed. In recent years, photovoltaic power generation, which is particularly developing, has advanced and has been used for light electricity, but it requires a large place due to the low solar energy, and it may change the environment on the ocean, cloudy weather, nighttime Pauses occur,
Although geothermal power generation is advantageous in Japan, it has not been realized in many practical applications due to difficulties such as location and construction. Wind power and wave power generation are weak without wind, and the difference in energy is strong,
Nevertheless, wind power has been installed experimentally in various places and is being commercialized in a small scale. As described above, natural clean power generation has its advantages and disadvantages, and each has its own problems in using it as practical heavy power.

SUMMARY OF THE INVENTION The present invention seeks to obtain a so-called beautiful power practically by utilizing waves having a high energy and averaging disadvantages having a great difference in the intensity of the energy as much as possible.

[0006] Furthermore, installation is conventionally difficult, and undersea construction is simplified, and power generation equipment costs are reduced by emphasizing onshore work, and maintenance and inspection of storms, shells, seaweed adhesion, etc. are facilitated. The purpose is to provide stable clean energy.

[0007]

According to a first aspect of the present invention, there is provided a wave collecting apparatus comprising: a wave collecting device; and a wind power generating device using the wave collecting device.

The valve seat, which is in contact with the upper surface of the cylinder bottom and has an opening corresponding to the bottom opening, passes through the front of the cylinder and forms a conical cylinder exhaust window. The lid and the valve seat are a conical cylinder exhaust valve, and the valve seat of the conical cylinder exhaust valve slides over the top of the cylinder bottom through the handle screw so as to protrude forward.

In addition, a half-moon-shaped wave return having a front opening opening downward and forward from the shoulder of the inner surface of the conical cylinder is fixed.

At the top of the in-cylinder handle screw at the top of the cone,
An intermediate bottom with an opening at the front 1/4 is provided, and a vertical partition is attached to the upper lid vertically from the upper surface.

[0011] In the power generating apparatus using the above-mentioned wave collecting device, four to five wave collecting devices are grouped into several groups, and then the ventilation pipes for each of the suction and exhaust air are collected and collected separately in the primary adjustment tank for each group. An air release valve is attached to both the intake and exhaust tanks, and a drain valve and a dust removal valve are attached to the exhaust tank side.

[0012] Further, through a vent pipe from each primary regulating tank to a large secondary regulating tank, air is collected to form a positive pressure tank and a negative pressure tank. Attach a ventilation shutoff valve to the ventilation pipe between the tank and the next adjustment tank.

Further, both ends of a positive / negative pressure ventilation pipe are respectively connected to a secondary regulating tank and a wind tunnel of a moving blade of a wind turbine utilizing positive / negative pressure difference of the tank, thereby rotating the wind turbine. This is a device that generates power using a wave collector that generates electricity with a generator that works with the shaft.

[0014]

When the wave power generator constructed as above is operated, the wave is received by the conical cylinder and the conical cylinder (FIG. 1) integrated with the skirt of the skirt, and the vertical movement of the wave is amplified by the conical taper. Then, the air in the upper part of the conical cylinder is compressed and stored in the primary adjustment tank and the positive pressure tank (FIGS. 4 and 5) of the large secondary adjustment tank through the exhaust valve and the ventilation pipe.

Conversely, the air in the negative pressure tank of the large secondary adjustment tank is sucked into the primary adjustment tank and the conical cylinder through the intake valve of the cylinder above the conical cylinder via a vent pipe.

Using the pressure difference between the positive pressure tank and the negative pressure tank of the secondary adjustment tank and the air flow, the rotor rotates with the moving blade of the wind turbine and generates electric power with a shaft-linked generator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The above-mentioned construction and operation will be described in more detail with reference to the drawings. In the wave collecting device shown in FIGS. 1 and 2, when a wave is received by a conical cylinder 1 and a hakama 2 on the lower rear side thereof, the conical cylinder 1

Drainage and discharge of garbage are performed by a drain valve and a garbage removal valve mounted on the tank, and at the same time, the pressure of each group of wave collectors is adjusted.

The primary-adjusted group of exhaust gas is further passed through a secondary vent pipe 10 for each group, and a large secondary adjustment tank 11 is formed.
Into a positive pressure tank. Conversely, the negative pressure tank of the secondary adjustment tank 11 passes through the negative pressure side of the secondary ventilation pipe 10, passes through the primary adjustment tank 9 of the intake air, and is sucked into each wave collecting device. Pressure adjustment of positive pressure and negative pressure in the secondary adjustment tank 11 is performed by the pressure adjustment valve 12, and both pressure tanks are connected to both ends of the wind tunnel of the rotor blade 14 of the wind turbine 13, and the wind turbine 13 is rotated and interlocked. The generator 15 generates electric power.

In addition, for stable power generation (so-called clean power), about 50 wave collecting devices are installed (the larger the number, the better). For example, in the case of stormy weather, 30 units are operated and the others are stopped by the ventilation shutoff valve 21 and the primary adjustment tank 9 The intake and exhaust are released by the air release valve, and when the waves are quiet, 50 units are fully operated to stabilize the wind power before the secondary adjustment tank 11 as much as possible.
