Description

Technical Field

[0001] This utility model relates to the field of explosion-proof valve technology, and more specifically, to an active electrical cabinet explosion-proof valve. Background Technology

[0002] As a safety device, explosion-proof valves play an irreplaceable role in the safety of energy storage system operation. When a battery cell in an energy storage system experiences thermal failure, the decomposition of the electrolyte inside the cell generates a large amount of flammable waste gas. This gas is discharged into the battery box through the explosion-proof valve on the cell casing. The gas then accumulates inside the battery box until it reaches the pressure limit of the explosion-proof valve on the battery box wall, at which point it is discharged into the energy storage system cabinet. To prevent the flammable waste gas in the energy storage system from spontaneously combusting or exploding upon contact with an open flame during this process, the explosion-proof valve can be opened at this time to promptly discharge the gas inside the energy storage system cabinet to the outside of the energy storage system, reducing the possibility of safety accidents.

[0003] In existing technologies, valves with covers controlled by electromagnetic locks are typically installed on the cabinets of energy storage systems. When the electromagnetic lock is unlocked, the cover pops out and opens relative to the explosion-proof valve, opening the vent to release air. However, the cover of this type of electromagnetic lock explosion-proof valve cannot close automatically, often requiring manual intervention to re-lock the cover to the valve body and close the vent. Therefore, this type of explosion-proof valve cannot adjust its opening or closing in a timely manner according to circumstances, increasing the workload of relevant personnel and affecting the preparation time for the energy storage system to return to normal operation. Therefore, how to provide an automatic opening and closing explosion-proof valve to achieve timely response and avoid cumbersome operation has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an active electrical cabinet explosion-proof valve to solve the above-mentioned technical problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an active electrical cabinet explosion-proof valve, comprising: a valve seat and a valve body; an exhaust hole is provided on the valve seat, an mounting plate is provided on the valve seat, a drive assembly is provided on the mounting plate, a connecting assembly is provided at the output end of the drive assembly, the connecting assembly is fixed to the valve body, and the drive assembly is used to drive the valve body to open or close the exhaust hole.

[0006] Specifically, after the pressure inside the electrical cabinet reaches the preset value, the drive component starts to push the valve body to move away from the valve seat. At this time, the vent hole opens, and the gas inside the electrical cabinet can be discharged from the vent hole. After the venting inside the electrical cabinet is completed, the pressure inside the electrical cabinet is less than the preset value. The drive component then drives the valve body to move towards the valve seat. At this time, the valve body closes the vent hole on the valve seat, realizing the automatic opening and closing of the explosion-proof valve.

[0007] Optionally, the valve seat is provided with a mounting base, the valve seat has a clearance hole adapted to the drive assembly, the mounting base has a through hole corresponding to the clearance hole, the mounting plate has two oblong holes, a fixing screw is provided in the oblong holes, and the fixing screw passes through the oblong holes and is threaded to the mounting base.

[0008] Specifically, during assembly, the drive assembly passes through the through hole and the clearance hole in sequence and then connects to the valve body. By adjusting the position of the fixing screw in the oblong hole, the position of the drive assembly on the mounting plate is adjusted so that the initial position of the drive assembly can pull the valve body tight onto the valve seat.

[0009] Optionally, a limiting groove adapted to the mounting base is provided on the mounting plate.

[0010] Specifically, the limiting groove can restrict the position of the mounting base, ensuring that the mounting base remains within the limiting groove when the mounting plate moves.

[0011] Optionally, the connecting assembly includes: a connecting plate and a connector; the connecting plate has a connecting hole, one end of the connector passes through the connecting hole and is fixed to the driving assembly, the valve body has a mounting groove, and the connecting plate is embedded in the mounting groove and fixed to the valve body.

[0012] Specifically, during assembly, after the mounting plate is installed on the mounting base, the connecting plate is fixed to the output end of the drive component through the connector. After the connecting plate is embedded in the mounting groove, it is fixed to the valve body with screws to achieve the assembly of the valve body and the connecting plate. This assembly method only requires the connecting plate to be embedded in the mounting groove, which makes it easy to connect the valve body to the output end of the drive component.

[0013] Optionally, the mounting plate has a fitting groove; the drive assembly is disposed within the fitting groove.

[0014] Specifically, by setting a fitting groove, when the air pressure inside the electrical cabinet is high, the groove wall can block the position of the drive component, improve the connection stability between the drive component and the mounting plate, and prevent the connection between the drive component and the mounting plate from loosening due to air pressure.

[0015] Optionally, the valve body is provided with a plurality of guide rods; the plurality of guide rods are evenly distributed on the valve body, and the valve seat is provided with a plurality of guide holes adapted to the plurality of guide rods, and the guide rods are slidably connected to the guide holes.

[0016] Specifically, when the drive assembly pushes the valve body to move linearly, the guide rod can restrict the movement path of the valve body and improve the stability of the valve body's linear motion.

[0017] Optionally, a waterproof flange is provided on the valve seat, and a waterproof ring is provided on the valve body, wherein the waterproof ring is engaged with the waterproof flange.

[0018] Specifically, the waterproof flange and waterproof ring can prevent moisture from entering the electrical cabinet from the connection between the valve seat and the valve body, thus improving the sealing effect of the valve body and the valve seat.

[0019] Optionally, a sealing ring is provided on the valve seat, and a waterproof boss is provided on the valve body, with the sidewall of the waterproof boss abutting against the sealing ring.

[0020] Specifically, by setting a sealing ring and a waterproof boss, the sealing effect of the valve seat and valve body can be further improved.

[0021] In summary, this utility model has the following beneficial effects: After the pressure inside the electrical cabinet reaches the preset value, the drive component starts to push the valve body to move away from the valve seat. At this time, the exhaust port opens, and the gas inside the electrical cabinet can be discharged from the exhaust port. After the exhaust is completed, the pressure inside the electrical cabinet is less than the preset value. The drive component drives the valve body to move towards the valve seat. At this time, the valve body closes the exhaust port on the valve seat. By driving the valve body to move through the drive component, the explosion-proof valve can be automatically opened and closed. Attached Figure Description
