Technical Field
[0001] This utility model relates to the field of energy storage technology, and in particular to an explosion-proof exhaust valve for energy storage equipment. Background Technology
[0002] With the continuous increase in energy demand and the ongoing adjustment of the energy structure, energy storage devices that address the imbalance between power supply and demand and improve energy utilization efficiency have strong application prospects.
[0003] Energy storage devices store electrical energy in battery packs. When excess energy is stored, heat is generated during storage and release, potentially causing an imbalance in pressure between the inside and outside of the device and creating a safety hazard. Therefore, explosion-proof vent valves are required on the top of energy storage devices. When the detection system detects that the internal temperature, pressure, smoke, or toxic gas (CO) exceeds safety thresholds, the explosion-proof vent valve opens to release pressure, quickly balancing the pressure and handling extreme pressure conditions.
[0004] Traditional explosion-proof vent valves installed on top of energy storage devices are usually embedded, which makes them prone to water accumulation. The presence of water can not only cause sealing problems, but may also seep into the energy storage device when the valve is opened, creating a safety hazard. Utility Model Content

[0030] Combination Figure 1 , Figure 2 and Figure 3 This utility model discloses an explosion-proof exhaust valve for an energy storage device according to one embodiment, including: a base 10, a sealing sleeve 20, a cover plate 30, and a power component 40.
[0031] The base 10 is used to install on the top of the energy storage device. The upper surface of the base 10 is provided with a boss 12, and the boss 12 is provided with a vent 101. The outer side wall of the vent 101 forms an annular protrusion 14.

[0034] The cover plate 30 is rotatably connected to the base 10.
[0035] Specifically, the cover plate 30 can be rotated relative to the base 10 to open or close the vent 101. When the cover plate 30 is rotated relative to the base 10 to the point where it is stacked on the boss 12, the inner side of the cover plate 30 abuts against the sealing sleeve 20, thereby closing the vent 101.
[0036] A power assembly 40 is used to drive the cover plate 30 to rotate relative to the base 10.
[0037] Preferably, in conjunction with the accompanying drawings, in this embodiment, the inner side of the cover plate 30 is provided with a first heat insulation layer 36.

When the detection system inside the energy storage device detects that the temperature, pressure, smoke, or toxic gas (CO) inside the energy storage device exceeds the safety threshold, the control power component 40 drives the cover plate 30 to rotate relative to the base 10, thereby opening the vent 101 to release pressure, quickly balance the pressure, and cope with extreme pressure.
