This application relates to the field of battery structure, and in particular to a thermal runaway protection device and a battery. The thermal runaway protection device includes a flame-retardant shell, extinguishing gas, and multiple extinguishing bags; each extinguishing bag includes a filling bag and extinguishing material; the extinguishing material is placed inside the filling bag, which ruptures at a first preset temperature; the flame-retardant shell has a receiving cavity, and multiple extinguishing bags are spaced apart within the receiving cavity, which is filled with extinguishing gas; the flame-retardant shell ruptures at a second preset temperature, where the first preset temperature is greater than or equal to the second preset temperature. The thermal runaway protection device provided by this application, by placing extinguishing bags and extinguishing gas inside the flame-retardant shell, allows the high temperature to rupture the flame-retardant shell when thermal runaway occurs, releasing the extinguishing gas from the receiving cavity into the battery pack for oxygen removal and isolation. Simultaneously, the filling bag of the extinguishing bag ruptures due to heat, releasing the extinguishing material, which forms foam or dry powder to cover the surface of the fire source, inhibiting the occurrence and development of combustion.

The invention relates to the technical field of fire-fighting robots, and discloses a fire rescue robot anti-collision structure based on visual feedback. High-pressure water flushing protection mechanisms are arranged on the two sides of the fire-fighting robot. The high-pressure water flushing protection mechanism comprises a U-shaped pipe, control equipment and a plurality of high-pressure nozzles; the fire-fighting robot is further provided with induction equipment. The sensing device monitors the surrounding environment in real time, when obstacles in the advancing direction are detected, high-pressure water flow is sprayed out in advance through the high-pressure spray head for buffering, and surrounding residual fire is extinguished. The high-pressure water flushing protection mechanism can be rotatably stored, a U-shaped pipe of the high-pressure water flushing protection mechanism is composed of a curved pipe and a rotatable straight pipe, and the conversion between a buffering mode and a fire extinguishing mode is achieved by switching a high-pressure spray head and a diffusion spray head. And an anti-collision fence structure is arranged on the periphery and is linked with the spray head to form a water cushion effect to enhance buffering. According to the robot, collision is actively prevented through visual feedback, multi-mode water spraying and anti-collision fence linkage are combined, and the anti-collision capacity and the fire extinguishing efficiency of the robot are remarkably improved.

The application discloses an electric energy metering box, and relates to the technical field of power distribution equipment. The box body cooperates with a box door to enclose a closed cavity. A fire sensing device and an air pressure sensor are integrated in the cavity. Telescopic isolation components are arranged on the box door corresponding to each electrical element. Independent fire extinguishing components and pneumatic driving components are matched. A high-pressure gas source device and a main pipeline assembly are simultaneously carried. When a fire occurs, the closed cavity simultaneously carries out oxygen reduction by air extraction. The high-pressure gas source drives corresponding movable covers to extend, individually covering the electrical element on fire. Then, the independent fire extinguishing components spray fire extinguishing agents at fixed points to achieve single-point accurate fire extinguishing. After the fire is eliminated, the structure automatically resets after pressure relief. The application can block the spread of fire, avoid the influence on the intact electrical circuit, and effectively reduce the loss of electrical fire, thereby improving the safety of power distribution operation and the stability of power supply.
