本発明は、余剰エネルギを圧縮空気として貯蔵
する装置を水底に沈設する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of sinking a device for storing surplus energy as compressed air on the bottom of water.
（従来の技術及び問題点）
発電所の電力供給能力が向上している一方で、
電力需要の昼間と夜間とにおける差が増大してい
る。したがつて、夜間の余剰電力を何らかの形態
で蓄積し、これを昼間に供給することとすれば、
電力供給能力を差程大きくしなくともすむし、ま
たその能力を十分に活用することができる。(Conventional technology and problems) While the power supply capacity of power plants is improving,
The difference in electricity demand between daytime and nighttime is increasing. Therefore, if we store surplus electricity at night in some form and supply it during the day,
There is no need to increase the power supply capacity, and the capacity can be fully utilized.
そこで、従来上記夜間の電力を貯えるためにい
くつかの方策が提案され、あるいは実施されてい
る。 Therefore, several measures have been proposed or implemented in order to store the above-mentioned nighttime power.
先ず、最も一般的な手段としては、夜間の余剰
電力で揚水池に水を揚水して、昼間にこれを発電
に利用する揚水発電があるが、これは揚水発電所
の設置には地理上そして地形上の制約があり、容
易ではない。 First of all, the most common method is pumped storage power generation, in which water is pumped into a pumped storage pond using surplus electricity at night and used for power generation during the day, but this is due to geographical and It is not easy due to geographical constraints.
また、上記余剰電力で圧縮空気を作り、これを
貯蔵して昼間の再発電に備える方法も提案されて

等の付帯工事も要し、さらには空間容積が一定の
ため貯蔵される空気圧は変動してしまい一定圧力
の出力として利用できない等の多くの問題点を有
している。 A method has also been proposed in which compressed air is produced using the surplus electricity and stored to prepare for regeneration during the day. In this case, the storage space requires a large volume and must withstand high pressure. Therefore, a hole is dug underground and used as a reservoir-like space structure that balances the ground pressure. However, in the case of the above-mentioned underground space structure, digging a hole itself is extremely difficult except when using a mining hole, additional work such as preventing air leakage is required, and furthermore, the space volume is limited to a certain level. Therefore, there are many problems such as the stored air pressure fluctuates and cannot be used as a constant pressure output.
そこで、上記地下貯蔵における問題を解決する

さいので、クレーン船等にかかる負担は大きい。
さらには、装置は通常、大型で重量も大きく必ず
しも設計時の重量とはなつていない。そのために
作業に不手際を招く虞れがある。 Therefore, in order to solve the above-mentioned problems in underground storage, an air storage tank that is sunk to the bottom of the water is also known. In this known device, the bottom of the air storage tank is completely open, through which water can freely enter and exit, and the water level in the tank is brought to a level in equilibrium with the air pressure. There is. In order to sink such a device to a predetermined water bottom, a method of suspending the device from a crane ship, a barge with a suspension winch, or the like and lowering the device to the water bottom can be considered. At this time, since the bottom of the air storage tank is always open, water flows in from the bottom, air is compressed at the top, and the pressures of both are balanced and fall. Therefore, since the amount of air is small and the resulting buoyancy is small, the load placed on the crane ship, etc. is large.
Furthermore, devices are typically large and heavy, and are not necessarily as designed. This may lead to clumsiness in the work.
また、装置の製作所から沈設位置まで装置を曳

る。 Furthermore, when towing the equipment from the equipment manufacturing facility to the submerged location, a considerable amount of water enters the storage tank, which creates a large amount of resistance and places a heavy burden on the towing boat.

The purpose of this project is to provide a method for sinking water to the bottom of the water.

ことによつて構成される。 According to the invention, the above object is to provide a ballast tank at or around the bottom and storage above or in contact with the ballast tank, in order to store compressed air at the bottom of the water under a pressure balanced with external water pressure. The air storage tank has an air supply pipe connected to an air supply pipe communicating with a compressed air source on the ground or on the water at the upper part, and an opening through which water from the bottom of the water passes through at the lower part. In the method of sinking the storage device to the bottom of the water, the internal space of the air storage tank is kept at atmospheric pressure, the opening is sealed, the compressed air storage device is towed to the water above the sinking position, and the above-mentioned method is carried out using hanging equipment above the water. Suspending the compressed air storage device, compressed air is sent into the air storage tank from the air supply pipe, and the opening is opened to allow water to flow in;
The compressed air storage device is stored while maintaining a state in which the water pressure and air pressure of the incoming water are balanced so that the weight of the compressed air storage device including the amount of water is below the specified value allowed for hanging equipment. It consists of lowering the device to the bottom of the water and submerging it.

のもののみを開放するようにすればよい。 According to the present invention, the work of installing the compressed air storage device on the bottom of the water and the work of pulling it up from there can be done very effectively. During the above work, it is important that the weight of the entire device is within a certain range. That is, the weight must be less than the capacity of a suspension device such as a winch of a work boat that suspends the device on the water. Therefore, in the present invention, the weight of the device itself and the ballast is balanced with the buoyancy in the air storage tank based on the compressed air sent during operation, and the weight is kept within the above-mentioned certain range. In this case, in the present invention, the overall weight of the device, which is a large structure, may not always match the design value, and in consideration of this, the opening of the air storage tank adjusts the amount of water in the tank. This makes it possible to keep the weight of the entire device including the amount of water within the above-mentioned certain range.
Various measures can be considered to adjust the amount of water, such as adjusting the pressure of compressed air in an air storage tank equipped with valves in the vertical direction, or providing multiple openings in the air storage tank above and below to remotely control the amount of water. It is only necessary to open only those at a predetermined position by operation.
さらに、バラストタンク自体も開閉自在として

際、内部を空にして軽量とすることができ、きわ
めて曳行が楽になる。 Furthermore, if the ballast tank itself can be opened and closed, when the device is towed to the installation location on the water, the interior can be emptied and the weight can be reduced, making towing extremely easy.

Figure 1 is a vertical cross section of the apparatus of this embodiment installed on the bottom of the water, Figure 2 is a partial plan view of the apparatus shown in Figure 1, and Figures 3 A to E are overviews showing the installation procedure of the apparatus shown in Figure 1. It is a diagram.
圧縮空気貯蔵装置は、第１図のごとく下部にバ
ラストタンク１そして上部に貯気槽２が一体的に
形成されている。 As shown in FIG. 1, the compressed air storage device is integrally formed with a ballast tank 1 at the bottom and an air storage tank 2 at the top.

脚１２が複数位置で下方に向け突出している。 The ballast tank 1 is formed over almost the entire area of the lower part of the device and is equipped with an on-off valve 11, but after being sunk to the bottom of the water, it is in a sealed state with water filled inside. That is, it is completely isolated from the air storage tank 2. Further, on the bottom of the ballast tank, legs 12 that bite into the ground G protrude downward at a plurality of positions.
貯気槽２は、上部にて、地上もしくは水上の圧

いて任意の一つが開口できる等の方策によつて、
貯気槽２内の空気圧の加減によつて貯気槽２内の
水量Ｈが任意に調整できるようになつている。 The upper part of the air storage tank 2 is connected to an air pipe 21 that communicates with a compressed air source on the ground or on the water. For example, the compressed air source is a compressor at a power plant that produces compressed air using surplus electricity at night. An opening 22 communicating with the outside is provided in the lower part of the air storage tank 2. In a preferred embodiment, a plurality of openings 22 are provided in the vertical direction so that any one can be opened.
The amount of water H in the air storage tank 2 can be adjusted arbitrarily by adjusting the air pressure in the air storage tank 2.

また、貯気槽２の上部外面には、設置時に装置

を駆動して発電を行うこととなる。 In the device submerged at the bottom of the water, compressed air produced from surplus electricity at a power plant at night is sent into an air storage tank 2 through an air pipe 21 and stored there.
Since the air storage tank 2 communicates with the outside through the opening 22, water from the outside is injected or drained here, and the air pressure inside and the water pressure outside are balanced. That is, the air pressure is always stored at the same pressure as the external water pressure. Thus, the air stored under water pressure is sent to the power plant through the air pipe 21 during daytime hours when the demand for electricity is high, where it drives a generator to generate electricity.
次に、上述のごとくの実施例装置を、製造所か

でこれを引き上げる際の要領について説明する。 Next, a description will be given of the procedures for transporting the above-described embodiment apparatus from the manufacturing site until it is submerged, and when it is lifted up for the purpose of repair or the like.

図Ａ参照）。 First, the compressed air storage device completed at the manufacturing facility is kept in a lightweight state by emptying the ballast tank 1 and the storage tank 2, and closing the on-off valve 11 and opening 22 to prevent water from entering from the outside. It is towed to the surface of the water where it is planned to be immersed (3rd
(See Figure A).

きるために水の抵抗は軽減される。 Next, while the above-mentioned device is suspended by the chain 5 from the suspension part 4 by the crane of the work boat, the on-off valve 11 of the ballast tank 1 and the opening 2 of the air storage tank 2 are suspended.
2 is opened, and the air supply pipe 2 is inserted into the air storage tank 2.
Compressed air is sent through 1. Then, the third
Water flows into the ballast tank 1 as shown in Figure B, and the device begins to settle due to increased weight as shown in Figure 3C. On the other hand,
The air storage tank containing compressed air acts as a floating body because water is removed from the opening 22, and together with the weight of the ballast tank, it reduces the weight acting on the crane and allows it to descend slowly. (See Figure 3C). At that time, in order to keep the weight acting on the crane within a certain range, the air storage tank 2
The volume occupied by the air in the air storage tank 2, that is, the amount of water in the air storage tank 2, is adjusted by adjusting the air pressure fed into the tank. When the amount of water in the air storage tank 2 is adjusted in this way, the total weight of the air storage tank 2 and the ballast tank 1, including the water, falls within the above-mentioned certain range.
(See Figure 3D). Further, the amount of water in the air storage tank 2 can be set without adjusting the air pressure. That is, for example, the opening 22 of the air storage tank 2
If a plurality of openings 22 are provided in the vertical direction, the compressed air sent from the air pipe 21 is set at high pressure, and if one of the plurality of openings 22 is selected, the excess air is released to the outside. The amount of water is maintained at the level of the selected opening. Note that during the settling, the water at the bottom of the ballast tank can also move upward through the water passage holes 3, so that water resistance is reduced.
かくして、第３図Ｅに示されるごとく水底に
沈設された装置は、バラストの重量さらにはバ

脚１２によつて安定して設置される。かかる、
状況下において、既述した要領で本装置は使用
される。 Thus, the equipment sunk to the bottom of the water as shown in FIG. 3E is stabilized by the weight of the ballast and by the feet 12 provided at the bottom of the ballast tank and biting into the ground. It takes,
Under the circumstances, the device is used as described above.
次に、何らかの要因、例えば修理等のために

地盤との間には、通水孔３を通して水が流入す
るので、いわゆる地盤への吸着作用はなくなり
引上げが容易である。 Next, due to some factors, such as when lifting the device for repairs, etc., the reverse operation,
That is, a predetermined amount of compressed air is sent into the storage tank 2 through the air pipe 21, the water inside is discharged from the opening 22, and the tank is lifted out in a lightened state using a crane or the like. At this time, since water flows into the space between the bottom of the ballast tank and the ground through the water holes 3, there is no so-called adsorption effect on the ground, and the ballast tank can be easily pulled up.

る。(Effects of the Invention) As described above, when installing a compressed air storage device on the bottom of the water, the present invention secures the weight necessary for descent in the ballast tank, and adjusts the amount of compressed air in the air storage tank. By feeding air, it is possible to obtain buoyancy and reduce the force applied to the crane, and even if the weight of the equipment itself is not at the design value, the amount of water in the air storage tank can be adjusted by adjusting the compressed air pressure mentioned above, etc. The weight of the entire device including water can be set to a set value, resulting in the effect that ease of work and safety are ensured. Furthermore, if the ballast tank is also emptied when the device is towed from the facility where it is manufactured to the water area where it will be sunk, the burden on the towing boat will be reduced.
