Description
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

When the cover plate is rotated relative to the base to the point where the cover plate is stacked on the protrusion, the sealing protrusion is embedded in the vent, thereby closing the vent.
[0009] The power assembly disposed in the receiving part includes a motor and a steering gear. The rotation shaft of the motor is not parallel to the shaft. The rotation shaft of the motor is connected to the input end of the steering gear. The output end of the steering gear is connected to one end of the shaft.

[0014] In one embodiment, the sidewall of the vent forms an annular protrusion facing upwards, and a sealing sleeve is fitted onto the annular protrusion;
[0015] When the sealing protrusion is embedded in the vent, the sealing protrusion abuts against the sealing sleeve.
[0016] In one embodiment, the boss is provided with a mounting base, and the other end of the rotating shaft is rotatably connected to the mounting base.

The protrusion design avoids water accumulation, thereby improving the safety of the explosion-proof exhaust valve of this utility model.
[0022] Furthermore, the provision of the second insulation layer and the first insulation layer significantly improves the heat preservation performance of the explosion-proof exhaust valve of the energy storage device of this invention, thereby enabling the explosion-proof exhaust valve of the energy storage device of this invention to have an anti-condensation function.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] 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 cover plate 20 and a power component 30.
[0028] 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 a receiving part 14. The boss 12 is provided with a vent 101. The lower surface of the base 10 is provided with a first heat insulation layer 16.
[0029] A rotating shaft 22 is fixed to the bottom of the cover plate 20. The rotating shaft 22 is rotatably mounted on the base 10, so that the cover plate 20 and the base 10 are rotatably connected. A second heat insulation layer 24 is provided on the inner side of the cover plate 20. A sealing protrusion 26 matching the vent 101 is provided on the second heat insulation layer 24.

[0030] The power unit 40 is used to drive the cover plate 30 to rotate relative to the base 10.

[0035] Furthermore, the provision of the second insulation layer 24 and the first insulation layer 16 significantly improves the heat preservation performance of the explosion-proof exhaust valve of the energy storage device of this invention, thereby enabling the explosion-proof exhaust valve of the energy storage device of this invention to have an anti-condensation function.
[0036] When in use, the explosion-proof exhaust valve of this utility model is installed on the top of the energy storage device. Under normal conditions, when the cover plate 20 rotates relative to the base 10 until the cover plate 30 is stacked on the boss 12, the sealing protrusion 26 is embedded in the vent 101, thereby closing the vent 101. 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 30 drives the cover plate 20 to rotate relative to the base 10, thereby opening the vent 101 to release pressure, quickly balance the pressure, and cope with extreme pressure.
