At this time, start the water pump 303 and the fan 310. The water pump 303 draws the water in the water tank 301 through the first water pipe 302 and sends it to the second water pipe 304. The water in the second water pipe 304 enters the first hose 305 and then enters the cooling pipe 306 through the first hose 305 to dissipate heat and cool the protection unit body 2. The used water enters the second hose 307 and enters the water tank 301 through the third water pipe 309. The large amount of water in the water tank 301 and the fan 310 cooperate to cool the used water, which facilitates the recycling of water and improves the cooling effect.

[0039] (2) Pull the two pull rods 405 in opposite directions. The pull rods 405 drive the movable plate 404 to move and squeeze the spring 402 and the telescopic rod 403. The movable plate 404 will also drive the clamping rod 406 to move. At this time, move the protection unit body 2 between the two shells 401, release the pull rod 405, and the movable plate 404 will reset under the action of the spring 402, driving the clamping rod 406 to move, so that the clamping rod 406 is clamped into the inside of the clamping slot 407, thereby installing and fixing the protection unit body 2 and facilitating disassembly and maintenance.
