Two U-shaped blocks are fixedly connected to the top of the inner wall of the switch cabinet body, and a plurality of fixed rods are fixedly connected between the two U-shaped blocks. The outer walls of the plurality of fixed rods are rotatably connected to fan plates, and a water storage tank is provided inside the fan plate. Two T-shaped water inlet grooves are provided on the top of the rain shield, and the inner wall bottoms of the two T-shaped water inlet grooves are fixedly connected to the same U-shaped tube, and the top of the U-shaped tube is fixedly connected to a plurality of hoses, and the plurality of hoses are remotely connected to the switch cabinet body.

A slide groove is opened on the side of the fan plate, and the inner wall of the slide groove is slidably connected with a U-shaped rod. The top of the U-shaped rod is fixedly connected to the bottom of the long block. The side of the fan plate is fixedly connected with a water outlet pipe, and the water outlet pipe runs through the inner wall of the switch cabinet body. When it rains, rainwater will flow into the U-shaped tube through the T-shaped water inlet groove, and then enter the water tank inside the fan plate through the hose from the U-shaped tube, and then flow out from the water outlet pipe on the side of the water tank, so that the fan plate is kept in a cool state by the flow of rainwater, and then the motor is started. The output shaft of the motor will cause the shaft to rotate, and the rotation of the shaft will drive the fan blades to rotate, thereby cooling the electrical equipment inside the switch cabinet. At the same time, the rotation of the shaft will drive the short rod to rotate, and the rotation of the short rod will cause the circular rod to move back and forth along the inner wall of the protective frame. The back and forth movement of the circular rod will drive the connecting rod to move back and forth, and the back and forth movement of the connecting rod will drive the long block to move back and forth. The back and forth movement of the long block will drive the U-shaped rod to move back and forth, and the U-shaped rod will move back and forth on the inner wall of the slide groove, thereby driving the fan plate to move back and forth along the outer wall of the fixed rod through the slide groove, so that the airflow blown out by the fan blades will bring the cool air on the surface of the fan plate into the interior of the switch cabinet body.

[0007] The U-shaped fins are connected to the outer wall of the fan plate in a sliding manner, and the right top of each of the U-shaped fins is fixedly connected to the same interference rod, and the side of the U-shaped block is fixedly connected to an arc plate, and the side of the arc plate is fixedly connected to a plurality of ball blocks, a spring is arranged between the end of the interference rod away from the ball block and the fan plate, and the end of the interference rod close to the ball block is arranged in an arc shape, and the plurality of ball blocks are located on the displacement trajectory of the interference rod.

The movement of the interference rod will cause one end of its arc to contact the ball block, thereby causing the interference rod to compress the spring at its end away from the ball block, and when the arc end of the interference rod does not contact the ball block, the spring will drive the interference rod to reset through its own elastic force, and so on and so forth, so that the interference rod can realize reciprocating motion, and the reciprocating motion of the interference rod will drive the U-shaped fin to move back and forth.

[0008] According to the above technical solution, a dehumidification device for absorbing moisture in the air is arranged on the top of the connecting rod, and the dehumidification device includes an L-shaped rod, the bottom of the L-shaped rod is fixedly connected to the top of the connecting rod, the end of the L-shaped rod away from the connecting rod is fixedly connected to a dehumidification block, and the top of the protective frame is fixedly connected to a track block for moving the dehumidification block. When external air flows into the switch cabinet body through the fan blades, the dehumidification block absorbs moisture in the air, and at the same time, the back and forth movement of the connecting rod drives the L-shaped rod to move back and forth, and the back and forth movement of the L-shaped rod drives the dehumidification block to move back and forth.

[0009] According to the above technical solution, the top of the circular rod is fixedly connected with an arc block 1, the top of the inner wall of the protection frame is fixedly connected with a T-shaped rod, the outer wall of the T-shaped rod is slidably installed with a semi-arc rod, the top of the semi-arc rod is fixedly connected with a plurality of pressure rods, the outer wall of the semi-arc rod is fixedly connected with an L-shaped long rod, the end of the L-shaped long rod away from the semi-arc rod is fixedly connected with an arc block 2, a spring is arranged between the semi-arc rod and the protection frame, the arc block 2 is located on the displacement track of the arc block 1, and the dehumidification block is located on the displacement track of the plurality of pressure rods At the same time, the back-and-forth movement of the circular rod will drive arc block one to move back and forth, and the movement of arc block one will conflict with arc block two, thereby causing arc block two to move upward. The movement of arc block two will drive the L-shaped long rod to move, and the movement of the L-shaped long rod will drive the half-arc rod to move. The movement of the half-arc rod will squeeze the spring between it and the protective frame, and the movement of the half-arc rod will drive the pressure rod to squeeze the surface of the dehumidification block, thereby avoiding the problem of the dehumidification block being exposed to the outside for a long time and becoming hardened, when the movement of arc block one does not conflict with arc block two.

When the arc block 2 moves upward, the arc block 2 drives the fixed block, the U-shaped plate, the connecting plate, the L-shaped connecting block, and the pressing block to move upward. Because the inner wall of the T-shaped water inlet groove in contact with the pressing block is an inclined surface, a gap will appear between the pressing block and the inclined surface of the inner wall of the T-shaped water inlet groove when the pressing block moves upward.

[0029] When in use, when it rains, rainwater flows into the U-shaped pipe 513 through the T-shaped water inlet 512, then enters the water storage tank 511 inside the fan plate 510 through the hose 514 from the U-shaped pipe 513, and then flows out from the water outlet pipe on the side of the water storage tank 511, so that the fan plate 510 is kept cool by the flow of rainwater, and then the motor 52 is started, and the output shaft of the motor 52 causes the rotating shaft 521 to rotate, and the rotation of the rotating shaft 521 drives the fan blades 53 The rotation of the rotating shaft 521 drives the short rod 54 to rotate, and the rotation of the short rod 54 causes the circular rod 55 to move back and forth along the inner wall of the protection frame 51. The back and forth movement of the circular rod 55 drives the connecting rod 56 to move back and forth. The back and forth movement of the connecting rod 56 drives the long block 57 to move back and forth. The back and forth movement of the long block 57 drives the U-shaped rod 516 to move back and forth. The U-shaped rod 516 moves back and forth on the inner wall of the slide groove 515.

[0031] See also Figure 1-8 On the basis of the above-mentioned embodiment, in another embodiment of the present invention, a pressurizing device 7 for accelerating the flow of water in the T-shaped water inlet groove 512 is provided on the top of the arc block 68 .

Through the arrangement of the above structure, the movement of the L-shaped connecting blocks 74 will drive the pressing blocks 75 to move inside the T-shaped water inlet groove 512, thereby generating pressure inside the T-shaped water inlet groove 512, increasing the speed at which rainwater enters the U-shaped tube 513, and at the same time, when the pressing blocks 75 move upward, a gap will appear between the inclined surface of the inner wall of the T-shaped water inlet groove 512, thereby avoiding the problem of sucking out rainwater from the inner wall of the U-shaped tube 513 by pressure when the pressing blocks 75 move upward.

[0033] When in use, when the arc block 68 is reset, the arc block 68 will drive the fixed block 71 to move downward, the movement of the fixed block 71 will drive the U-shaped plate 72 to move, the movement of the U-shaped plate 72 will drive the connecting plate 73 to move, the movement of the connecting plate 73 will drive the L-shaped connecting block 74 to move, and the movement of the L-shaped connecting block 74 will drive the pressing block 75 to move inside the T-shaped water inlet groove 512, thereby generating pressure inside the T-shaped water inlet groove 512, increasing the pressure of rainwater entering into the The speed of the U-shaped tube 513, when the arc block 2 68 moves upward, the arc block 2 68 drives the fixed block 71, the U-shaped plate 72, the connecting plate 73, the L-shaped connecting block 74, and the pressing block 75 to move upward. Because the inner wall of the T-shaped water inlet groove 512 in contact with the pressing block 75 is set as an inclined surface, when the pressing block 75 moves upward, a gap will appear between the inclined surface of the inner wall of the T-shaped water inlet groove 512, thereby avoiding the problem of the pressing block 75 sucking out the rainwater on the inner wall of the U-shaped tube 513 by pressure when moving upward.
