Description

Active explosion-proof valve for electric cabinet Technical Field The utility model relates to the technical field of explosion-proof valves, in particular to an active electric cabinet explosion-proof valve. Background The explosion-proof valve is used as a safety device and has an irreplaceable effect on the safety of the operation process of the energy storage system. When the battery core of the energy storage system is in thermal failure, a large amount of combustible waste gas can be generated by electrolyte decomposition in the battery core and is discharged into the battery box through the explosion-proof valve of the battery core shell, and the gas can be accumulated in the battery box until reaching the pressure limit value of the explosion-proof valve on the wall of the battery box, and the waste gas is discharged into the cabinet body of the energy storage system, so that the damage of the combustible waste gas in the energy storage system, such as spontaneous combustion when encountering open fire, explosion and the like, can be avoided, the explosion-proof valve can be opened at the moment, the gas in the cabinet body of the energy storage system is timely discharged to the outside of the energy storage system, and the possibility of safety accidents is reduced. In the prior art, valves employing electromagnetic lock control cover plates are typically installed on energy storage system cabinets. When the electromagnetic lock is unlocked, the cover plate pops up and opens relative to the explosion-proof valve, and the exhaust hole is opened, so that exhaust is realized. However, the cover plate of the electromagnetic lock explosion-proof valve cannot be automatically closed, and the cover plate and the explosion-proof valve main body are often required to be locked and installed again by manual arrival, so that the exhaust hole is closed. Therefore, the explosion-proof valve cannot be timely adjusted to be opened or closed according to the situation, the workload of related staff is increased, and the preparation time for the energy storage system to recover to the normal operation state is influenced. Therefore, how to provide an automatic opening and closing explosion-proof valve to realize timely response of the explosion-proof valve, avoiding complex operation, has become a problem to be solved urgently by those skilled in the art. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide an active explosion-proof valve for an electric cabinet so as to solve the technical problems. The technical aim of the utility model is achieved by the following technical scheme that the active type electric cabinet explosion-proof valve comprises a valve seat and a valve body, wherein the valve seat is provided with an exhaust hole, the valve seat is provided with a mounting plate, the mounting plate is provided with a driving assembly, the output end of the driving assembly is provided with a connecting assembly, the connecting assembly is fixed with the valve body, and the driving assembly is used for driving the valve body to open or close the exhaust hole. Specifically, after the pressure in the electric cabinet reaches a preset value, the driving assembly starts to push the valve body to move in a direction away from the valve seat, the exhaust hole is opened at the moment, gas in the electric cabinet can be exhausted from the exhaust hole, after the exhaust in the electric cabinet is completed, the pressure in the electric cabinet is smaller than the preset value, the driving assembly drives the valve body to move towards the valve seat, and at the moment, the valve body seals the exhaust hole on the valve seat, so that the explosion-proof valve is automatically opened and closed. Optionally, the valve seat is provided with a mounting seat, a hole for letting away is formed in the valve seat, the hole is adapted to the driving assembly, a through hole corresponding to the hole for letting away is formed in the mounting seat, two kidney-shaped holes are formed in the mounting plate, fixing screws are arranged in the kidney-shaped holes, and the fixing screws penetrate through the kidney-shaped holes and are in threaded connection with the mounting seat.
