[0025] By providing a thermosensitive glass column 307, it can automatically break and remove the support limit for the slider 304 when a fire occurs and the temperature is higher than 68°C. By providing a slider 304, a spring 305 and a push rod 306, and the push rod 306 is slidably inserted into the inside of the slide groove 207, so that after the slider 304 loses the support of the thermosensitive glass column 307, the spring 305 can push the slider 304 to drive the push rod 306 to move, and use the slide groove 207 to push the rotating arm 206 to rotate the air valve 205 to open the fire extinguishing operation.

[0026] See also Figure 3-5 The bottom end of the air supply pipe 2 is fixedly connected to the gas cylinder 201, and the gas cylinder 201 is fixedly sleeved with a clamp 202. The top of the air supply pipe 2 is fixedly connected to the gas distribution pipe 203, and the bottom of the side wall of the gas distribution pipe 203 is fixedly connected to the nozzle 204. The air supply pipe 2 is fixedly connected to the air valve 205, and the top of the air valve 205 is rotatably connected to the rotating arm 206. The upper surface of the rotating arm 206 is penetrated by a slide groove 207. The clamp 202 is fixedly connected to the bottom of the inner cavity of the power cabinet body 1, and the gas distribution pipe 203 and the nozzle 204 are arranged at the top of the inner cavity of the power cabinet body 1.

[0027] By setting up a gas cylinder 201, carbon dioxide gas can be released to extinguish the fire when a fire occurs inside the power cabinet body 1. By setting up an air supply pipe 2 and a gas distribution pipe 203, the gas in the gas cylinder 201 can be transported to the upper part of the inner cavity of the power cabinet body 1, and the nozzle 204 is used to exhaust and extinguish the fire.

[0028] Working principle: When a small outdoor power cabinet is used, in the initial state, first, the cabinet door 101 and the ventilation groove 102 are set on the front of the power cabinet body 1. At the same time, a mounting plate 103 is installed inside the power cabinet body 1 to facilitate the installation and protection of electrical equipment. A gas cylinder 201 is fixed to a clamp 202 fixed at the bottom of the inner cavity of the power cabinet body 1. The gas outlet end of the gas cylinder 201 is connected to the air supply pipe 2, and the other end of the air supply pipe 2 is connected to the gas distribution pipe 203 and the nozzle 204 set at the top of the inner cavity of the power cabinet body 1, so as to facilitate jet fire extinguishing from top to bottom. The air valve 205, rotating arm 206 and slide 207 set on the air supply pipe 2 are connected to the air supply mechanism 3 installed at the top of the inner cavity of the power cabinet body 1, so as to facilitate rapid opening for fire extinguishing when a fire occurs;

[0029] When it is necessary to quickly extinguish a fire in the power cabinet body 1, first, when the electrical equipment in the power cabinet body 1 catches fire, the flames spread upward and hot air gathers above the inner cavity of the power cabinet body 1. After the temperature above the inner cavity of the power cabinet body 1 exceeds 68°C, the heat-sensitive glass column 307 bursts due to heat, and the slider 304 moves toward the second connecting block 302 under the push of the spring 305 without the support force. Since the bottom of the slider 304 is connected to the push rod 306, and the push rod 306 is inserted into the slide groove 207 opened at the top of the rotating arm 206, the push rod 306 will use the slide groove 207 to push the rotating arm 206 to drive the internal valve core of the gas valve 205 to rotate and open, so that the carbon dioxide gas in the gas cylinder 201 is transported to the gas distribution pipe 203 through the gas supply pipe 2, and finally discharged by the nozzle 204 to extinguish the fire and cool down the electrical equipment in the power cabinet body 1. This device is convenient for quickly extinguishing a fire in the power cabinet body 1.
