汲み上げた冷水との温度差を利用し、フロン等の作動流
体を介して発電を行っていた。Conventionally, the ocean thermal energy conversion method has been mainly used in tropical regions, and utilizes the temperature difference between high-temperature seawater near the sea surface and cold water pumped from the deep sea by a pump, and generates electricity through a working fluid such as fluorocarbon. It was generating electricity.
上述した従来の海洋温度差発電方式は、深海部より冷水

ンプを作動するために電力を消費し、そのため発電効率
が悪くなるという欠点がある。The above-mentioned conventional ocean temperature difference power generation method uses a pump to pump cold water from the deep sea, so it consumes electricity to operate the pump, which has the disadvantage of decreasing power generation efficiency.

でいる。The ocean temperature difference power generation method of the present invention is an ocean temperature difference power generation method that uses the temperature difference between seawater on the seabed and seawater near the sea surface to generate electricity, and includes: a seawater pool that is provided near the sea surface and stores seawater at high tide; A seawater reservoir provided on the seabed, a water pipe that allows the seawater collected in the seawater pool at high tide level to fall into the seawater pool as the tide level falls, and the seawater in the seawater pool is installed at a height near the sea surface. and a pumping pipe leading to the power generation device.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の縦断面図である。FIG. 1 is a longitudinal sectional view of one embodiment of the present invention.

地上の発電装置８へと押し上げられる。この時、海底溝
水溜６は外部の冷水により内部の水が冷却される必要が
あるために熱交換効率が良い材料、形状であることが必
要であり、又、汲上管７に於ては、冷水が海面近くの熱
水により温められることを防止するために断熱材９で覆
っておく必要がある。A seawater inlet 2 and a suction valve 3 for opening and closing the seawater inlet 2 are provided on the bottom of a seawater pool 1 fixed at a position above the sea surface, and the suction valve 3 is opened only at high tide to pump seawater into the seawater pool 1. Hold. When the tide level drops, by opening the valve 4 on the bottom of the seawater pool 1, the seawater stored in the seawater pool 1 passes through the water pipe 5 and becomes the same as the seawater pool 1 above the water surface, which is installed several hundred meters below the seabed. The water flows into the submarine trench water reservoir 6 which has a volume. Due to this lick, the cold water in the submarine trench sump 6 passes through the pumping pipe 7 connected to the lower part of the submarine trench sump 6 and is pushed up to the power generation device 8 on the ground. At this time, since the water inside the submarine trench sump 6 needs to be cooled by external cold water, the material and shape must have good heat exchange efficiency. It is necessary to cover the cold water with a heat insulating material 9 to prevent it from being heated by hot water near the sea surface.
地上の発電装置８に於ては、熱水吸入管１０から流入す

る。In the power generation device 8 on the ground, a working fluid 1 such as fluorocarbons heated by hot water on the sea surface flowing in from a hot water suction pipe 10
1 rotates a turbine 12 to generate electricity, and the working fluid 11 is cooled by cooling water flowing in from the pumping pipe 7.
温度差発電は熱水と冷水との両方を得ることが必要であ
るため赤道付近の熱帯地方に設置するのが効率的に有利
であるが、赤道付近に於ては引力の関係で数ｍという大
きな潮位差を得ることができるため、本方式の深海の冷
水を押し上げる圧力を確保することは容易である。Temperature difference power generation needs to obtain both hot water and cold water, so it is efficient to install it in tropical regions near the equator, but near the equator, it is several meters away due to gravitational force. Since a large tidal level difference can be obtained, it is easy to secure the pressure to push up the cold water in the deep sea using this method.
又、より一層高温の熱水を得るために、南方の強い太陽
熱を利用することも可能である。更に、本発明の方式を
従来のポンプによる汲み上げ方式と併用することも可能
である。It is also possible to utilize the strong solar heat in the south to obtain even higher temperature hot water. Furthermore, it is also possible to use the method of the present invention in conjunction with conventional pumping methods.
以上説明したように本発明は、潮位差という自然のエネ
ルギーを使用して、従来使用していた冷水汲み上げポン
プ用の動力なしで冷水を汲み上げることにより、発電効
率を上げることができる効果がある。As explained above, the present invention has the effect of increasing power generation efficiency by using the natural energy of the tidal level difference to pump up cold water without the power of the conventionally used cold water pump.
