Rack plates 13 are movably connected to both sides of the top of the electrical equipment body 1. A flame retardant box 11 is provided at the top of the inner cavity of the electrical equipment body 1, and both sides of the bottom of the flame retardant box 11 are rotatably connected to limit plates 12. A gear 15 is fixed to the surface of the limit plate 12, and one side of the gear 15 is meshed with one side of the rack plate 13. Rebound structures 14 are provided on both sides of the inner cavity of the electrical equipment body 1, and a number of drainage holes 21 are connected to both sides of the inner side of the electrical equipment body 1.

[0023] The rebound structure 14 includes a movable groove 141, a fixed rod 142, a movable block 143 and a spring 144. The movable groove 141 is opened on both sides of the inner cavity of the electrical equipment body 1, the fixed rod 142 is fixed inside the movable groove 141, the inside of the movable block 143 is fixed to the surface of the fixed rod 142, one side of the movable block 143 is fixed to the bottom of one side of the rack plate 13, and the spring 144 is sleeved on the surface of the fixed rod 142. The two ends of the spring 144 are respectively fixed to the movable groove 141 and the movable block 143. In this way, as the rack plate 13 moves, the movable block 143 will be driven to move together. During the movement, the spring 144 will be squeezed. When the movable block 143 is not subjected to force, the elastic force of the spring 144 itself can be used to drive the movable block 143 and the rack plate 13 back to the starting position.

[0030] Working principle: In the process of using the electrical equipment body 1, the smoke sensor will always sense inside the electrical equipment body 1. If smoke is generated, the water pump 4 will start and extract the water source inside the water tank 3, and then transport it to the inside of the fixed pipe 6 through the water outlet pipe 5, and then transport it to the inside of the cavity 2. As the water source enters, part of the water source will pass through the inside of the folding tube 8, thereby pushing up the top pipe 9 and driving the baffle 10 to move upward. During the movement, the drainage hole 21 will be exposed on the inner side of the electrical equipment body 1, and part of the water source will flow out through the drainage hole 21, and the baffle 10 will block the heat dissipation hole 7, thereby blocking the entry of outside air, so that the interior of the electrical equipment body 1 is in an oxygen-free environment, so that the fire cannot continue to burn. At the same time, as the baffle 10 moves upward, it will apply force to the rack plate 13, and drive the gear 15 to rotate, and at the same time drive the limit plate 12 to expand downward, and the flame retardant inside the flame retardant box 11 will fall downward, thereby achieving a fire prevention effect.
