Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
As shown in fig. 1-2, the present embodiment provides an underwater energy storage power station that mainly includes a prefabricated cabin 100. The prefabricated cabin 100 is a waterproof concrete member, and the prefabricated cabin 100 can be installed under water; the battery room 200 and the electric appliance room 300 which are isolated from each other are arranged in the prefabricated cabin 100, a battery pack assembly is arranged in the battery room 200, and an electric control assembly is arranged in the electric appliance room 300 and is electrically connected with the battery pack assembly. A water inlet 210 is formed in the side wall of the battery chamber 200, and the water inlet 210 is communicated with the battery chamber 200; a water outlet (not shown in the figure) is formed in the bottom of the battery chamber 200, and the water outlet is communicated with the battery chamber 200; so that external water can enter the battery chamber 200 through the water inlet 210 to extinguish the fire of the battery pack assembly and then flow out through the water outlet.
Based on the above design, the prefabricated cabin 100 in this embodiment is a waterproof concrete member, that is, may be formed by casting compression-resistant waterproof concrete, that is, the prefabricated cabin 100 may be prefabricated in advance by simply constructing and then be placed under water, thereby shortening the construction period and saving time and cost. The prefabricated cabins 100 may be disposed in natural lakes, artificial reservoirs, or artificial ponds for use.
Alternatively, the battery pack assembly includes a battery rack and a plurality of battery packs provided on the battery rack, and the monitoring, electrical components, etc. may be installed in the electrical compartment 300.
Further, in actual operation, the prefabricated cabin 100 is manufactured in two ways: firstly, the cabin 100 body can be prefabricated, and then facilities (a battery pack assembly, fire protection, pipelines, monitoring, wire harnesses, electrical components and the like) are carried in the cabin and installed and debugged; in the second way, the facilities (battery pack assembly, fire protection, piping, monitoring, electrical components, etc.) may be installed on the ground first, and then the prefabricated cabin 100 is poured by casting.
As shown in fig. 1 to 2, the battery compartment 200 and the electric appliance compartment 300 are sealed and isolated by a partition 400, and a door opening 410 may be provided on the partition 400 to facilitate the operation of an operator between the battery compartment 200 and the electric appliance compartment 300. A fire fighting zone 310 is provided in the electric room 300, the fire fighting zone 310 is isolated from the electric room 300, and a fire extinguishing assembly (not shown) is placed in the fire fighting zone 310. For example, the fire extinguishing assembly may be provided as a carbon dioxide fire extinguisher. The underwater energy storage power station further comprises a gas pipeline (not shown in the figure), one end of the gas pipeline is communicated with the fire extinguishing assembly, and the other end of the gas pipeline is arranged towards the battery pack assembly. When the battery pack assembly is out of control, the external controller can control the fire extinguishing assembly to be opened, so that carbon dioxide gas is sprayed to the battery pack assembly along the gas pipeline, and the fire extinguishing of the battery pack assembly is realized.
Further, in the present embodiment, a drain pump is provided at the water outlet, and is configured to drain water in the battery compartment 200. The water inlet 210 is provided with a first one-way valve, and the water outlet is provided with a second one-way valve. Meanwhile, a spraying pipeline (not shown in the figure) is arranged in the battery chamber 200, one end of the spraying pipeline is communicated with the first one-way valve, and the other end of the spraying pipeline is arranged towards the battery pack assembly. When the battery pack assembly is in a fire and the gas fire protection (fire extinguishing assembly) cannot be eliminated, the external controller can control the first one-way valve to be opened, so that external water can flow into the battery chamber 200 through the jet pipeline under the action of water pressure, and the battery pack assembly is sprayed to extinguish the fire. After the fire is extinguished, the controller can control the first check valve to be closed and the second check valve to be opened, so that the water in the battery chamber 200 is discharged to the outside under the driving action of the drainage pump, and meanwhile, the water cannot enter the prefabricated cabin 100 from the outside. Through the gas fire extinguishing mode and the water fire extinguishing mode, the safety performance of the underwater energy storage power station is improved, and the whole fire extinguishing process is finished underwater, so that the danger to the surrounding environment of the land can be reduced.
It should be noted that, the working principles of the fire extinguishing assembly, the first check valve and the second check valve controlled by the controller in this embodiment belong to the prior art, and are not repeated here.
The prefabricated cabin 100 in this embodiment is surrounded by water under water, and has a relatively constant underwater temperature, so that the prefabricated cabin can have a good heat preservation and cooling effect on the underwater energy storage power station.
Optionally, in this embodiment, a fan (not shown in the figure) is disposed in the battery compartment 200, and the fan is used to dissipate heat from the battery pack assembly. Of course, in addition to the air cooling mode, the battery compartment 200 may also be cooled by liquid cooling to dissipate heat from the battery pack assembly.
In this embodiment, the underwater power station further comprises a stairway (not shown in the figure), the top of the electrical compartment 300 is provided with a stairway inlet 500 protruding from the stairway inlet 500 into the electrical compartment 300. The stair entrance part 500 is higher than the water surface by a preset distance, which is not less than 2 meters, for example, the preset distance can be set to 2.5 meters, so that an operator can conveniently enter the electric appliance room 300 through the stair entrance to perform equipment installation, inspection, detection maintenance and other works.
Compared with the prior art, in the embodiment, operators can process and manufacture the prefabricated cabin 100 in advance, can be directly placed under water when needed, and do not need to occupy land area, so that the construction period is shortened, the manpower and material resources are reduced, and the cost is saved. When thermal runaway of the battery pack occurs, external water can flow into the battery chamber 200 through the water inlet 210 to extinguish fire, and the danger to the surrounding environment is reduced. The prefabricated cabin 100 is made of a firm material (such as compression-resistant waterproof concrete), meets waterproof standards, has high structural strength, has strong wind and wave resistance, corrosion resistance and pressure resistance, and can prevent damage to equipment caused by external influences. In addition, the temperature under water is relatively constant, and the underwater energy storage power station can be well insulated and cooled.
