[0026] Working principle: The safety isolation device for energy storage batteries is a device designed to provide electrical isolation in a battery system. Its main function is to prevent the battery from being damaged and causing safety accidents in the case of overcharging, over-discharging, and short circuits. An energy storage battery is a device that can convert electrical energy into chemical energy and store it. It can convert the stored chemical energy into electrical energy for use when needed. The isolation device can wrap and cover the energy storage battery. After the energy storage battery is placed inside the isolation device, the traditional isolation device does not have a moisture-proof structure at the bottom. The installation environment of the isolation device is diverse. When in a humid environment, moisture will gradually corrode the bottom of the isolation housing 1, and a new isolation device needs to be replaced, reducing the practicality of the isolation device. The explosion-proof film layer 3 can bear the pressure when the pressure inside the isolation housing 1 rises abnormally, playing an explosion-proof role. Rotating the twisting rod 11 clockwise will drive the two clamping blocks 7 to move relatively, and then drive the two fitting plates 9 to move relatively. A plurality of clamping sleeves 10 will also move accordingly. One side of the plurality of clamping sleeves 10 can clamp both sides of the energy storage battery pack 2, enhancing the stability of the energy storage battery pack 2 inside the isolation housing 1 and improving the practicality of the isolation device. The compression-resistant cover plate 12 can support the bottom of the energy storage battery pack 2. The moisture-proof plate 13 is made of silicate moisture-proof coating, mainly used to prevent the humid environment from damaging the compression-resistant cover plate 12 and extending the service life of the isolation device. After the compression-resistant cover plate 12 is corroded and damaged, the staff can rotate the four limit bars 15 in the reverse direction to disengage the limit bars 15 from the isolation housing 1, so as to facilitate the replacement of a new compression-resistant cover plate 12 alone. The four L-shaped blocks 14 are respectively fitted with both sides of the isolation housing 1. The compression-resistant cover plate 12 and the isolation housing 1 can be limited and fixed by using the four limit bars 15. Therefore, the damaged compression-resistant cover plate 12 can be replaced. The flame-retardant plate 4 and the top of the isolation housing 1 are threadedly connected through a plurality of positioning bars 16. After rotating the plurality of positioning bars 16 in the reverse direction, the isolation housing 1 and the flame-retardant plate 4 can be disassembled from each other, facilitating the maintenance and observation of the energy storage battery pack 2.
