Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof, in particular to an explosion-proof power device for a fire-fighting robot. Background Art

[0002] The design of explosion-proof special robots must strictly comply with relevant national explosion-proof standards. After product design is complete, they must undergo testing and certification by the National Explosion-Proof Research Institute to obtain an explosion-proof product certificate. There are many types of explosion-proof special robots, such as firefighting robots. Firefighting robots are intelligent devices used for firefighting and rescue operations in high-risk environments. They often face extreme conditions such as fire, high temperatures, and explosions, requiring explosion-proof design for their power units. Explosion-proof power units are protective devices used to protect critical power equipment from external explosions or fires, and they must also have a pressure relief device in the event of a power source loss of control.

[0003] The utility model with authorization announcement number CN218182373U discloses an explosion-proof warehouse body for a motor-powered robot. This utility model integrates the motor and electrical control system into the explosion-proof warehouse body, and uses steel plates, steel bars and square tubes to weld the warehouse body and other components. This not only reduces the weight of the warehouse body and saves costs, but also ensures the pressure resistance of the entire cavity after assembly.

[0004] The above device can achieve the purpose of explosion-proofing the exterior of the warehouse body. However, since the battery is inside the warehouse body and is not separated from the motor and electrical control system, once the battery short-circuits or other accidents cause the battery to explode, and there is no pressure relief device on the warehouse body, there is a great safety hazard. Therefore, a safer explosion-proof power device is needed. Utility Model Content
