After the wind enters the air duct box, it blows downward along the air duct box, passes through one side of the cabinet to the bottom of the cabinet, and then blows upward to the other side of the cabinet. At this time, the wind will blow into the interior of the cabinet from each small filter on the air duct box. The small filter can further filter dust and other impurities to prevent dust from entering the cabinet. The U-shaped design of the air duct box can send wind to the bottom of the cabinet to achieve full ventilation of the cabinet; S2: When the heat flow in the cabinet is gathered inside, a temperature difference is formed between the inside and outside of the cabinet, causing air heat convection.

At the same time, the upward movement of the disc pushes the slide bar to slide upward along the water inlet plate. The sliding of the two slide bars can push the U-shaped plate upward, and the conical block on the U-shaped plate moves upward accordingly and vibrates the filter, which can shake impurities such as leaves accumulated on the filter to both sides to prevent the filter from being blocked. When the water level in the water tank drops, the disc, the water plug and the buoyancy ball are reset under the action of gravity; S4: The rotation of the arc-shaped blade drives the disc to rotate, the rotation of the disc drives the rotating rod to rotate, the rotating rod drives the convex block to rotate, the protruding part of the convex block will intermittently squeeze the long rod, the long rod slides left and right along the support ring after being stressed, the stirring plate on the long rod slides left and right with the long rod, the sliding of the stirring plate can stir the desiccant in the drying box to prevent the desiccant from agglomerating; S5: At the same time, the rotation of the rotating rod drives the triangular plate to rotate, and the three cylinders on the triangular plate rotate accordingly, two of which squeeze the first water pipe. Under the action of the pressure difference, the rainwater in the first water pipe flows out from the bottom of the water tank and flows along the direction of the arrangement of the first water pipe, and is divided into the second water pipe connected to the first water pipe. The rainwater in the first water pipe and the second water pipe passes through the bottom of the cabinet and moves up from the other side of the cabinet, and re-enters the water tank from the side of the water tank. The first water pipe and the second water pipe are arranged on the inner wall of the cabinet, which can initially achieve the effect of cooling and absorb the heat in the air duct box. The heat sinks on the first water pipe and the second water pipe can further absorb heat. S6: When the temperature in the cabinet is too high, the alloy wire shrinks due to the heat, and the shrinkage of the alloy wire pulls the first material box upward, and the pull rod in the first material box moves upward accordingly, and the pull rod pulls the piston upward and away from the long cylinder. At this time, the aluminum sulfate solution in the first material box flows out of the long cylinder and enters the second material box through the short cylinder; S7: At the same time, the long plate fixed to the first material box moves upward with the first material box, the long plate pushes the sliding plate to move upward along the suspension rod, the sliding plate pushes the circular plate to move upward and blocks the air outlet on the drying box, the U-shaped clamp rod fixed to the long plate moves upward synchronously with the long plate, the U-shaped clamp rod drives the ventilation plate to slide upward along the fixed plate, the two ventilation plates are thus misaligned and overlapped, and the sliding ventilation plate just blocks the air inlet gap of the fixed ventilation plate; S8: When the first material box moves up to a certain height, the bottom inner wall of the first material box contacts the hanging rod, and when the first material box moves up again, it pulls the hanging rod to move up synchronously, and the hanging rod pulls the long tube up and makes the long tube away from the short tube.

Each fixed plate 416 is fixedly connected to the cabinet 1, and a slide groove is opened on the side close to the ventilation plate 415. Aluminum sulfate solution is placed in the first material box 402, and sodium bicarbonate solution is placed in the second material box 408. When the temperature in the cabinet 1 is too high, the alloy wire 401 shrinks due to the heat, and the shrinkage of the alloy wire 401 pulls the first material box 402 to move upward, and the pull rod 403 in the first material box 402 moves upward accordingly. The pull rod 403 pulls the piston 404 to move upward and away from the long cylinder 405. At this time, the aluminum sulfate solution in the first material box 402 flows out of the long cylinder 405 and enters the second material box 408 through the short cylinder 407. In the material box 408, the long plate 410 fixed to the first material box 402 moves up with the first material box 402, and the long plate 410 pushes the slide plate 411 to move up along the suspension rod 413, and the slide plate 411 pushes the circular plate 412 to move up and block the air outlet on the drying box 206, and the U-shaped clamp rod 414 fixed to the long plate 410 moves up synchronously with the long plate 410, and the U-shaped clamp rod 414 drives the ventilation plate 415 to slide upward along the fixed plate 416, and the two ventilation plates 415 are thus misaligned and overlapped, and the sliding ventilation plate 415 just blocks the air inlet gap of the fixed ventilation plate 415, and when the first material box 402 moves up to a certain height, the bottom inner wall of the first material box 402 contacts the hanging rod 406, and when the first material box 402 moves up again, it pulls the hanging rod 406 to move up synchronously,The hanging rod 406 pulls the long tube 405 upward and moves the long tube 405 away from the short tube 407.

[0016] Working principle: when the motor 202 is working, the motor 202 drives the shaft at the axis to rotate, and the shaft drives the fan blades 203 to rotate. The rotation of the fan blades 203 can blow the wind outside the cabinet 1 into the air duct box 204 from the air inlet. The large filter 201 on the cabinet 1 can initially filter impurities such as wind and sand to prevent dust from entering the cabinet 1. After the wind enters the air duct box 204, it blows downward along the air duct box 204, penetrates from one side of the cabinet 1 to the bottom of the cabinet 1, and then blows upward into the other side of the cabinet 1. At this time, the wind will be blown into the interior of the cabinet 1 from each small filter 205 on the air duct box 204. The small filter 205 can further filter impurities such as dust to prevent dust from entering the cabinet 1. The U-shaped design of the air duct box 204 can send wind to the bottom of the cabinet 1, so as to achieve comprehensive ventilation of the cabinet 1 and increase the ventilation area inside the power cabinet. Since only a small part of the power cabinet can be ventilated, the heat inside the power cabinet can be discharged, and the heat dissipation efficiency of the power cabinet can be improved. When the heat flow in the cabinet body 1 is gathered inside, a temperature difference is formed between the inside and the outside of the cabinet body 1, resulting in air heat convection. At the same time, the multiple arc leaves 208 outside the cabinet body 1 rotate continuously under the action of natural wind force. The thin ring 209 is used to support the arc leaves 208, and the snap button 210 is used to fix the thin ring 209 on the rain shield 5. The cross rod 211 is used to fix the thin ring 209 to prevent it from deformation. Therefore, the rotation of the multiple arc leaves 208 can discharge the hot air and hot wind in the cabinet body 1 from the air outlet of the drying box 206 and the rain shield 5. The rotation of the arc leaves 208 can accelerate the air flow from bottom to top in the cabinet body 1, thereby realizing ventilation in the cabinet body 1, improving the heat dissipation efficiency of the power cabinet, and preventing heat from accumulating inside the power cabinet. The rainwater is collected by the rain collecting box 301, and the rainwater enters the water tank 304 along the cylinder 302. The filter 303 can filter impurities such as leaves to prevent them from entering the water tank 304. The rainwater enters the bottom of the water tank 304 through the circular hole of the water inlet plate 305. The filter 303 at the bottom of the water tank 304 further filters impurities to prevent the impurities from accumulating and blocking the first water pipe 312. When the water level in the water tank 304 gradually rises, the buoyancy ball 309 gradually moves upward under the action of buoyancy, and the buoyancy ball 309 pushes the disc 307 to gradually move upward, and the water plug 308 on the disc 307 moves upward accordingly, until the water plug 308 blocks the circular hole of the water inlet plate 305, and the rainwater stops entering the water tank 3 04, and at the same time, the disc 307 moves up to push the slide bar 306 to slide upward along the water inlet plate 305. The sliding of the two slide bars 306 can push the U-shaped plate 310 to move up, and the conical block 311 on the U-shaped plate 310 moves up accordingly and vibrates the filter screen 303, which can shake the impurities such as leaves accumulated on the filter screen 303 to both sides to prevent the filter screen 303 from being blocked. When the water level in the water tank 304 drops, the disc 307, the water plug 308 and the buoyancy ball 309 are reset under the action of gravity, and the rotation of the arc leaf 208 drives the disc 207 to rotate, and the rotation of the disc 207 drives the rotating rod 212 to rotate, and the rotating rod 212 drives the protrusion 317 to rotate, and the protrusion 317 The raised piece will intermittently squeeze the long rod 318. After the long rod 318 is stressed, it slides left and right along the support ring 319. The stirring plate 320 on the long rod 318 slides left and right with the long rod 318. The sliding of the stirring plate 320 can stir the desiccant in the drying box 206 to prevent the desiccant from agglomerating. Placing the desiccant in the drying box 206 can prevent the cabinet 1 from being too humid. At the same time, the rotation of the rotating rod 212 drives the triangular plate 313 to rotate, and the three cylinders 314 on the triangular plate 313 rotate accordingly. Two of the cylinders 314 squeeze the first water pipe 312. The rainwater in the first water pipe 312 flows out from the bottom of the water tank 304 under the action of the pressure difference and flows along the first water pipe 312. The rainwater flows in the direction of the arrangement of the first water pipe 312 and is divided into the second water pipe 315 connected to the first water pipe 312. The rainwater in the first water pipe 312 and the second water pipe 315 passes through the bottom of the cabinet 1 and then moves upward from the other side of the cabinet 1 and re-enters the water tank 304 from the side of the water tank 304. The first water pipe 312 and the second water pipe 315 are arranged on the inner wall of the cabinet 1, which can initially achieve the effect of cooling and absorb the heat in the air duct box 204. The heat dissipation plates 316 on the first water pipe 312 and the second water pipe 315 can further absorb heat, reduce the temperature inside the cabinet 1, prevent the temperature inside the power cabinet from being too high, and improve the heat dissipation efficiency of the power cabinet. When the temperature in the cabinet 1 is too high, the alloy wire 401 shrinks due to the heat, and the shrinkage of the alloy wire 401 pulls the first material box 402 upward, and the pull rod 403 in the first material box 402 moves upward accordingly, and the pull rod 403 pulls the piston 404 upward and away from the long cylinder 405. At this time, the aluminum sulfate solution in the first material box 402 flows out of the long cylinder 405 and enters the second material box 408 through the short cylinder 407. At the same time, the long plate 410 fixed to the first material box 402 moves upward with the first material box 402, and the long plate 410 pushes the slide plate 411 to move upward along the suspension rod 413. The slide plate 411 pushes the circular plate 412 to move upward and block the air outlet on the drying box 206. The U-shaped clamp rod 414 fixed to the long plate 410 moves upward synchronously with the long plate 410, and the U-shaped clamp rod 414 drives the ventilation plate 415 to slide upward along the fixed plate 416, so that the two ventilation plates 415 are dislocated Overlapping, the sliding ventilation plate 415 just blocks the air inlet gap of the fixed ventilation plate 415. When the first material box 402 moves up to a certain height, the bottom inner wall of the first material box 402 contacts the hanging rod 406. When the first material box 402 moves up again, it pulls the hanging rod 406 to move up synchronously. The hanging rod 406 pulls the long tube 405 up and makes the long tube 405 away from the short tube 407. The fixing ring 409 is used to fix the second material box 408. At this time, the circular plate 412 blocks the air outlet, and the ventilation plate 415 blocks the air inlet. The cabinet 1 is in a closed state. Aluminum sulfate enters the second material box 408 from the first material box 402, and reacts with the sodium bicarbonate in the second material box 408 to generate carbon dioxide. The carbon dioxide enters the cabinet 1 through the short tube 407, which can effectively prevent the cabinet 1 from catching fire and promptly play a role in extinguishing the fire to prevent the power cabinet from catching fire due to excessive temperature.

10. The method for using the power cabinet with high-efficiency heat dissipation function according to claim 9, characterized in that: include: S1: When the motor (202) is working, the motor (202) drives the rotating shaft at the axis to rotate, and the rotating shaft drives the fan blades (203) to rotate. The rotation of the fan blades (203) can blow the wind outside the cabinet (1) into the air duct box (204) through the air inlet. The large filter (201) on the cabinet (1) can initially filter impurities such as wind and sand, and prevent dust from entering the cabinet (1). After the wind enters the air duct box (204), it blows downward along the air duct box (204). The air passes through one side of the cabinet (1) to the bottom of the cabinet (1), and then blows upward into the other side of the cabinet (1). At this time, the air will be blown into the interior of the cabinet (1) from each small filter (205) on the air duct box (204). The small filter (205) can further filter dust and other impurities to prevent dust from entering the cabinet (1). The U-shaped design of the air duct box (204) can deliver the air to the bottom of the cabinet (1), thereby achieving full ventilation of the cabinet (1); S2: When the heat flow in the cabinet (1) is gathered inside, a temperature difference is formed between the inside and outside of the cabinet (1), causing air heat convection. At the same time, the plurality of arc-shaped leaves (208) outside the cabinet (1) rotate continuously under the action of natural wind force. The thin circular ring (209) is used to support the arc-shaped leaves (208), the snap buttons (210) are used to fix the thin circular ring (209) on the rain shield (5), and the cross rod (211) is used to fix the thin circular ring (209) to prevent its deformation. Thus, the rotation of the plurality of arc-shaped leaves (208) can discharge the hot air and hot wind in the cabinet (1) from the air outlet of the drying box (206) and the rain shield (5). The rotation of the arc-shaped leaves (208) can accelerate the air flow from bottom to top in the cabinet (1); S3: Rainwater is collected by the rain collecting box (301), and the rainwater enters the water tank (304) along the cylinder (302). The filter net (303) can filter impurities such as leaves to prevent them from entering the water tank (304). The rainwater enters the bottom of the water tank (304) through the circular hole of the water inlet plate (305). The filter net (303) at the bottom of the water tank (304) further filters impurities to prevent the impurities from accumulating and blocking the first water pipe (312). When the water level in the water tank (304) gradually rises, the buoyancy ball (309) gradually moves upward under the action of buoyancy, and the buoyancy ball (309) pushes the disc (307) to gradually move upward, and the water plug (308) on the disc (307) moves upward accordingly. Until the water plug (308) blocks the circular hole of the water inlet plate (305), rainwater stops entering the water tank (304), and at the same time, the disc (307) moves upward to push the slide bar (306) to slide upward along the water inlet plate (305). The sliding of the two slide bars (306) can push the U-shaped plate (310) to move upward, and the conical block (311) on the U-shaped plate (310) moves upward accordingly and vibrates the filter screen (303), so that impurities such as leaves accumulated on the filter screen (303) can be shaken to both sides to prevent the filter screen (303) from being blocked. When the water level in the water tank (304) drops, the disc (307), the water plug (308) and the buoyancy ball (309) are reset under the action of gravity; S4: The rotation of the arc-shaped leaf (208) drives the disc (207) to rotate, the rotation of the disc (207) drives the rotating rod (212) to rotate, the rotating rod (212) drives the protrusion (317) to rotate, the protrusion (317) intermittently squeezes the long rod (318), the long rod (318) slides left and right along the support ring (319) after being subjected to force, the stirring plate (320) on the long rod (318) slides left and right along the long rod (318), and the sliding of the stirring plate (320) can stir the desiccant in the drying box (206) to prevent the desiccant from agglomerating; S5: At the same time, the rotating rod (212) rotates to drive the triangular plate (313) to rotate, and the three cylinders (314) on the triangular plate (313) rotate accordingly, and two of the cylinders (314) squeeze the first water pipe (312). Under the action of the pressure difference, rainwater in the first water pipe (312) flows out from the bottom of the water tank (304) and flows along the direction of the first water pipe (312), and is divided into the second water pipe (315) connected to the first water pipe (312). After passing through the bottom of the cabinet (1), rainwater in the first water pipe (312) and the second water pipe (315) moves upward from the other side of the cabinet (1) and re-enters the water tank (304) from the side of the water tank (304). The first water pipe (312) and the second water pipe (315) are arranged on the inner wall of the cabinet (1), thereby achieving a preliminary cooling effect and absorbing heat in the air duct box (204). The heat dissipation plates (316) on the first water pipe (312) and the second water pipe (315) can further absorb heat. S6: When the temperature in the cabinet (1) is too high, the alloy wire (401) shrinks due to the heat, and the shrinkage of the alloy wire (401) pulls the first material box (402) upward, and the pull rod (403) in the first material box (402) moves upward accordingly. The pull rod (403) pulls the piston (404) upward and away from the long tube (405). At this time, the aluminum sulfate solution in the first material box (402) flows out of the long tube (405) and enters the second material box (408) through the short tube (407); S7: At the same time, the long plate (410) fixed to the first material box (402) moves upward along with the first material box (402), the long plate (410) pushes the slide plate (411) to move upward along the suspension rod (413), the slide plate (411) pushes the circular plate (412) to move upward and block the air outlet on the drying box (206), the U-shaped clamping rod (414) fixed to the long plate (410) moves upward synchronously with the long plate (410), the U-shaped clamping rod (414) drives the ventilation plate (415) to slide upward along the fixed plate (416), the two ventilation plates (415) are thus offset and overlapped, and the sliding ventilation plate (415) just blocks the air inlet gap of the fixed ventilation plate (415); S8: When the first material box (402) moves up to a certain height, the bottom inner wall of the first material box (402) contacts the hanging rod (406), and when the first material box (402) moves up again, it pulls the hanging rod (406) to move up synchronously, and the hanging rod (406) pulls the long tube (405) to move up and makes the long tube (405) away from the short tube (407). The fixing ring (409) is used to fix the second material box (408). At this time, the circular plate (412) blocks the air outlet, and the ventilation plate (415) blocks the air inlet. The cabinet (1) is in a closed state, and aluminum sulfate enters the second material box (408) from the first material box (402) and reacts with the sodium bicarbonate in the second material box (408) to generate carbon dioxide, and the carbon dioxide enters the cabinet (1) through the short tube (407).
