FULLY-SUBMERGED ENERGY STORAGE DEVICE

The present disclosure relates to the technical field of energy storage devices, and discloses a fully immersed energy storage device, which includes an energy storage device casing and a water pump. An insulation box is mounted inside the energy storage device casing, and the insulation box is assembled with an assembly plate thereon. A mounting platform is mounted on the assembly plate and assembled with an annular rack. A rotating groove is provided between the mounting platform and the annular rack. Balls are placed in the rotating groove. The mounting platform is assembled with an assembly block, on which a rotating shaft is mounted. The rotating shaft connects to a gear. The rotating shaft connects to a first assembly rod, to which a second assembly rod is connected. The second assembly rod connects to a fixed block, which is connected to an energy storage box. An energy storage battery pack is assembled inside the energy storage box. A spring slot is provided on the energy storage box, and a spring is received in the spring slot. The spring is connected to a buckle. A buckle block is mounted on the energy storage box and defines a block slot therein. A motor base is mounted on the energy storage device casing. A motor is mounted on the motor base. Through the cooperation of the motor and the gear, it solves the problem that the existing energy conversion will be accompanied by heat generation, which will damage the energy storage device.
