In order to provide a stable supply of electrical energy, load countermeasures during peak power usage during the daytime are an important issue. However, as nuclear power generation increases, load followability is poor, so pumped storage power generation that uses surplus electricity at night is becoming more important.

不適当である。 Pumped storage power generation is a system that uses a pair of reservoirs in mountainous areas with a large difference in elevation, and replaces electrical energy with the potential energy of water. However, this requires large-scale land acquisition and construction work in mountainous areas, which is economically inefficient.Furthermore, since it needs to be constructed in a mountainous area away from cities with large electricity demand, it is necessary to reduce power transmission equipment, power transmission losses, etc. There remains a problem. Moreover, this energy storage device is suitable for large-scale installations and is unsuitable for small-scale energy storage.

The present invention comprises a ceiling part, a floor part, and a wall part, which are placed underwater and communicate with piping provided in the pressurizing apparatus, through which compressed air compressed by a pressurizing apparatus installed on the water is communicated. In an underwater energy storage device that stores pressure energy in a hollow box body, the flange tube is formed to communicate with the hollow box body and stand outward from the ceiling, and the ceilings at both ends of the hollow box body. a water inlet formed near the section, an on-off valve provided at the water inlet, a water pipe provided inside the hollow box and communicating the water inlet with the vicinity of the floor, and a ceiling connected to the inside of the hollow box. A ventilation pipe is arranged adjacent to the ceiling part, one end of which is inserted into the flange tube, and the other end of which is arranged in a corner of the ceiling part.

In other words, when a hollow box is installed on the bottom of the water, the hollow box can be effectively utilized by closing the water pipe placed higher up and using the lower water pipe for inlet of seawater due to pressure changes. be able to.
第１図には本発明の第１実施例に用いられるエ
ネルギ貯蔵装置が示されている。
FIG. 1 shows an energy storage device for use in a first embodiment of the invention.
この実施例では海面１０へ浮上する浮体１２に
発電機１４、コンプレツサ１６がそれぞれ設置さ

るものであればよい。 In this embodiment, a generator 14 and a compressor 16 are respectively installed on a floating body 12 floating on the sea surface 10, and these are connected to a plant on land by a power transmission line 18 passing under the sea. generator 14
may be any device that generates electricity using pressurized air, such as a turbine generator.
発電機１４、コンプレツサ１６には開閉弁２
０，２２を介して配管２４が連通されている。こ
の配管２４は海中へ導かれ、その先端部が海底２
６付近で中空箱体２８の頂部へ連通されている。
この中空箱体２８は鋼材、コンクリート等で製作
されて内部が全て空気で充満された場合にも浮上
することがない十分な重さを有し、拘束手段を兼
ねた構造となつている。 The generator 14 and the compressor 16 have an on-off valve 2.
Piping 24 is connected through 0 and 22. This pipe 24 is led into the sea, and its tip end is connected to the seabed 2.
6, it is connected to the top of the hollow box body 28.
This hollow box body 28 is made of steel, concrete, etc., has sufficient weight to prevent floating even when the inside is completely filled with air, and has a structure that also serves as a restraining means.
中空箱体２８はこの実施例では下方が開口して
おり、この下端部付近には通水口３０が形成さ
れ、海水の出入口となつている。 In this embodiment, the hollow box body 28 is open at the bottom, and a water inlet 30 is formed near the lower end, which serves as an inlet and outlet for seawater.
このように構成される本実施例では、夜間等の
余剰電力を利用し、コンプレツサ１６によつて大

箱体２８内の圧縮空気３２は次第に中空箱体２８
内の海水を通水口３０を通して海中へと押し出
す。これによつて電気エネルギが圧縮空気の圧力
エネルギとして蓄積されることになる。 In this embodiment configured as described above, surplus power at night or the like is used to compress the atmosphere by the compressor 16 and send it through the pipe 24 to the hollow box body 28. In this case, the on-off valve 20 is naturally closed and the on-off valve 22 is opened. Therefore, the compressed air 32 inside the hollow box body 28 gradually moves to the hollow box body 28.
The seawater inside is pushed out into the sea through the water inlet 30. This results in electrical energy being stored as pressure energy of the compressed air.
中空箱体２８へ作用する水圧は内外でつり合つ
ており、作用する外力は浮力に拘する拘束手段と
しての重鍾等の荷重のみであるため、深度が深く
なつても中空箱体２８の構造は同等でよい。 The water pressure acting on the hollow box body 28 is balanced inside and outside, and the only external force acting on it is the load of a heavy plow, etc., which acts as a restraining means that restricts buoyancy, so the structure of the hollow box body 28 remains stable even when the depth increases. may be equivalent.

ギとして一時的に蓄積し、昼間時に再び電気エネ
ルギとして取り出すことができる。 When converting pressure energy into electrical energy, the on-off valve 22 is closed and the on-off valve 20 is opened. As a result, the compressed air 32 inside the hollow box body 28
is pushed up inside the pipe 24 by the pressure of seawater, and reaches the generator 14, where power generation is performed. This power is sent to a consumption site such as a plant through a power transmission line 18. Therefore, surplus power at night can be temporarily stored as pressure energy and extracted again as electrical energy during the day.
この発電機１４で発生された電力を海上の石油
堀削プラント等に用いることも当然可能である。 Of course, it is also possible to use the electric power generated by this generator 14 in an offshore oil drilling plant or the like.
