Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. In the battery sealing device provided by the embodiment of the present invention, five surfaces perpendicular to each other form a cavity position 1, and a compartment door 6 that can be pulled out and snapped together. The position 1 and the compartment door 6 integrally form a movable The space for closing the battery pack is characterized in that the door 6 and the bin 1 are provided with a tensioning device 2 for tightening the door and the bin when a fire o...

Abstract

The invention discloses a battery fire protection sealing device. The battery fire protection sealing device comprises a cavity bin space composed of five mutually perpendicular sides, and a bin doorcapable of being drawn out and buckled, and the bin space and the bin door integrally form a space capable of being closed and accommodating a battery pack; the battery fire protection sealing deviceis characterized in that the bin door and the bin space are provided with a tensioning device for tensioning the bin door and the bin space in the case of fire, and the tensioning device comprises anlinear actuator arranged on the bin space, a strong magnet block arranged at one side, close to the bin door, of the linear actuator, and an iron block arranged on the bin door and cooperating with the strong magnet block, when the inside of the battery is on fire, the strong magnet block on the tensioning device attracts the iron block on the bin door so as to further completely seal the bin doorand the bin space, smoke and fire are prevented from breaking out from the bin door, and safety is improved.

Description

technical field [0001] The invention relates to a sealing device, in particular to a battery fire-fighting sealing device. Background technique [0002] Many battery packs are usually used in energy storage power stations to store electrical energy. These multiple battery packs are placed together in a combined manner without any barriers between the battery packs. Once a fire occurs in one of the battery packs, it is easy to cause damage to the surrounding battery packs. All fires occurred, causing irreparable losses. Therefore, the safety issue of the battery pack is very important. At present, aerosol fire extinguishers are used in electric vehicles on the market to ensure the fire safety of battery packs. However, aerosol fire extinguishers are relatively expensive and small in size. When extinguishing a fire, they first spontaneously ignite and then swallow the oxygen in the battery box to prevent the fire from spreading. It is suitable for sealing small spaces. Howe...
