Abstract

PROBLEM TO BE SOLVED: To aim at utilizing typhoon energy on an ocean, generate power in a submerged wind power generation ship, and store the power in secondary batteries to be transported into the country and used as power sources for electric vehicles, therefore achieving a reduced fossil fuel for global warming countermeasures. SOLUTION: The power generation ship is of a submerged double-barrel type for reducing the influence of ocean waves and improving rolling stability. During power generation, a hydrofoil is set vertical and operated as a spoiler for preventing the power generation ship from drifting in the strong wind. The attitude of the hull is controlled by controlling the angles of four vertical vanes installed at the front and rear sides of the power generation ship. A super high speed computer system is used to predict the occurrence position and the moving direction of the typhoon. The power generation ship is moved from the nearest station for increasing the probability of meeting the power generation ship with the typhoon.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims at utilizing typhoon energy on the ocean for countermeasures against global warming, and is a series of comprehensive technologies such as wind power generation, secondary batteries, submersibles, and weather forecasting. Using the sufficient energy density of the typhoon, the secondary battery is charged with the power obtained by wind power generation. Used for driving electric vehicles. It does not generate CO2, is environmentally friendly, and is a decisive factor in global warming countermeasures.

[Prior art]

[0002] There are prior applications such as Japanese Unexamined Patent Publication No. Hei 6-159224 and Japanese Unexamined Patent Publication No. Hei 7-189884, a water surface navigating wind power generation device and a wind power generation device.

Since wind energy is proportional to the cube of wind speed, it is practical to generate power near the center of the typhoon, which has the fastest wind speed on the earth. Wind speed is 6 near the center of the typhoon
It may exceed 0 m, and the wave height is expected to be about 10 m, and sailing on water is disadvantageous from the viewpoint of safety.
Therefore, it is an essential condition that the power generation vessel body be operated under relatively calm water.

[0004] The idea of a high altitude wind power generator is considered to be incompatible with safe operation of aircraft. Sailing is the best option for navigating the surface of the water, and it seems unlikely that the wind and hydro natural energy will provide enough energy to make the ship sail in the desired direction. It is conceivable to electrolyze seawater and use hydrogen. However, considering the environmental impact of caustic soda, chlorine gas, etc., by-produced at that time, this method is not recommended.

[Problems to be solved by the invention]

[0005] Generally, wind power is installed as a fixed facility on land or near the shore, and it is left to wind.
Annual utilization rates tend to be lower. In addition, since the energy density is lower than that of a hydroelectric power generation or the like, a small and large output cannot be obtained. The purpose is to obtain a large amount of typhoon energy in the form of electric power from secondary batteries.

[Means for Solving the Problems]

An underwater power generation boat 1 driven by an electric motor 9 is provided with a group of windmills 4 and a vertical wing / sail 2 on the water. The vertical wing / sail 2 is used for controlling the direction of the hull on a plane, and in normal sailing, for sailing in a tailwind or crosswind. On a catamaran,
A hydrofoil and spoiler 3 is provided between the two bodies, and is used for trimming the hull during navigation, and functions as a spoiler so that the hull does not flow while the hydrofoil and spoiler 3 is vertical during power generation. In this way, the occupancy rate is improved by moving along with the typhoon using the power of the typhoon while generating electricity in the eastern half circle of the typhoon eye.

Since power is generated in the eastern half circle of the typhoon, the energy density is sufficient, and even a relatively small wind turbine 4 can obtain large power at high speed.

BEST MODE FOR CARRYING OUT THE INVENTION

Since the wind speed of a typhoon varies in the range of about 17 to 60 m / s, it is efficient to operate the windmill 4 at a speed corresponding to this. Although the AC frequency generated by the generator 6 naturally changes, it may be finally rectified to DC for charging.

Since the windmill 4 is exposed to strong winds mixed with seawater, it is desirable that the windmill 4 has as simple a structure as possible and is excellent in material against seawater for long-term stable operation. Therefore, variable pitch control of the wing is not performed. Rather, the load should be controlled so that the maximum power can be obtained at the wind speed at that time.

As shown in FIG. 4, the windmill 4 is put out on the water,
The generator 6 is installed in the body 1 of the underwater power generation boat, and the space between the generator 6 and the gear box 5 or the flexible joint is connected by a shaft, a watertight seal or the like. As a result, the center of gravity of the power generation boat 1 is lowered, the stability of the power generation boat 1 is improved, and the reliability of the generator 6 is improved.

【Example】

As shown in FIG. 1, between the underwater power generation vessel main body and the windmill above the water, waves and water droplets are required, so that a high height is required. From
Catamaran. By using a catamaran, ballast tanks are provided on the left and right hulls, which is convenient for attitude control of the hull.

The angles of the four vertical wings / sails 2 provided before and after the main body of the power generation ship with respect to the wind direction are controlled to control the attitude of the power generation body in the horizontal plane, such as horizontal translation, horizontal rotation, and the like.
Two hydrofoil / spoilers 3 are provided before and after the main body of the power generation boat, and the angle is changed during navigation by driving a normal electric motor to control floating, sinking, front-back inclination, and pitching of the power generation body. During power generation in a strong wind, the hydrofoil and spoiler 3 is made vertical to act as a spoiler for preventing the power generation boat main body from being washed away by the strong wind.

[0013] It is extremely important to improve the operating rate of a power generating boat to increase the probability that the power generating boat encounters a typhoon generated in a wide open sea. An ultra-high-speed computer system predicts the typhoon occurrence position, moving direction, etc., and moves from the nearest base, thereby increasing the probability that the typhoon will meet the power generation ship.

While generating electricity, it moves with the movement of the typhoon,
Charge the secondary battery. After moving to the waters near Japan, unload the truck loaded with secondary batteries to the port. Load the discharged secondary battery, move to the base by sailing or electric motor drive, and wait. In this movement, the vertical wing / sail 2 is operated depending on the wind direction as shown in FIG. 3 to sail on the water. Repeat this.

[0015] A communication line by a satellite line is required between the base and the power generation ship, and the position is confirmed by GPS, and the state of the power generation ship is monitored. In the future, remote unmanned control of power generation vessels will also be performed.

【The invention's effect】

Approximately 29 typhoons are generated annually, and the typhoon period is about 24 to 396 hours. Assuming that the probability that the typhoon meets the power generation vessel is 30%, the 400 MW power generation vessel 1
An average of 62,644 MWh per year can be expected on ships. The energy of a typhoon is huge, and more hydrogen energy can be obtained by increasing the number of power ships.

Unlike electric power, secondary battery energy can be efficiently accumulated and stored, and can cope with fluctuations in load. The abolition of fossil fuel and gasoline vehicles and the introduction of electric vehicles will also solve problems such as global warming and environmental pollution.
