When it rains, the rainwater will flow into the U-shaped pipe through the T-shaped water inlet groove, and then enter the water storage tank inside the fan plate through the flexible pipe from the U-shaped pipe, and then flow out from the water outlet pipe on the side of the water storage tank, so that the fan plate is kept in a cool state by the flow of rainwater. Then start the motor, the output shaft of the motor will make the rotating shaft rotate, the rotation of the rotating shaft will drive the fan blade to rotate, so as to cool the electrical equipment inside the switch cabinet. At the same time, the rotation of the rotating shaft will drive the short rod to rotate, the rotation of the short rod will make the looped rod move back and forth along the inner wall of the protection frame, the back-and-forth movement of the looped rod will drive the connecting rod to move back and forth, 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 chute, so as to drive the fan plate to move back and forth along the outer wall of the fixing rod through the chute, so that the air flow blown out by the fan blade will bring the cool air on the surface of the fan plate into the switch cabinet main body.

[0007] According to the above technical solution, a number of U-shaped fins are slidably connected to the outer wall of the fan plate. A same contact rod is fixedly connected to the right tops of the number of U-shaped fins. An arc plate is fixedly connected to the side surface of the U-shaped block. A number of spherical blocks are fixedly connected to the side surface of the arc plate. A spring is arranged between the end of the contact rod away from the spherical block and the fan plate.

At the same time, the back-and-forth movement of the fan plate will drive the U-shaped fins to move. The movement of the U-shaped fins will drive the contact rod to move. The movement of the contact rod will cause its arc-shaped end to contact the spherical block, so that the contact rod compresses the spring at its end away from the spherical block. When the arc-shaped end of the contact rod does not contact the spherical block, the spring will drive the contact rod to reset through its own elastic force. In this way, the contact rod realizes a reciprocating movement. The reciprocating movement of the contact rod will drive the U-shaped fins to move back and forth.

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

[0009] According to the above technical solution, an arc block one is fixedly connected to the top of the U-shaped rod. A T-shaped rod is fixedly connected to the top inner wall of the protection frame. A semi-arc rod is slidably installed on the outer wall of the T-shaped rod. A number of pressing rods are fixedly connected to the top of the semi-arc rod. An L-shaped long rod is fixedly connected to the outer wall of the semi-arc rod. An arc block two is fixedly connected to the end of the L-shaped long rod away from the semi-arc rod. A spring is arranged between the semi-arc rod and the protection frame. The arc block two is located on the displacement track of the arc block one. The dehumidifying block is located on the displacement track of the number of pressing rods. At the same time, the back-and-forth movement of the U-shaped rod will drive the arc block one to move back and forth. The movement of the arc block one will contact the arc block two, so that the arc block two moves upward. The movement of the arc block two will drive the L-shaped long rod to move. The movement of the L-shaped long rod will drive the semi-arc rod to move. The movement of the semi-arc rod will squeeze the spring between it and the protection frame. The movement of the semi-arc rod will drive the pressing rods to squeeze the surface of the dehumidifying block, thus avoiding the problem that the dehumidifying block is caked due to long-term exposure to the outside. When the movement of the arc block one does not contact the arc block two.

[0010] According to the above technical solution, a pressurizing device for accelerating the water flow in the T-shaped water inlet groove is arranged at the top of the second arc block. The pressurizing device includes two fixed blocks, the bottoms of the two fixed blocks are fixedly connected to the top of the second arc block, the tops of the two fixed blocks are fixedly connected with the same U-shaped plate, the top of the U-shaped plate is fixedly connected with a connecting plate, L-shaped connecting blocks are fixedly connected to both the left and right sides of the connecting plate, and pressing blocks are fixedly connected to the circumferences at the bottoms of the two L-shaped connecting blocks. The pressing blocks are slidably connected to the inner wall of the T-shaped water inlet groove. When the second arc block is reset, the second arc block will drive the fixed block to move downward, the movement of the fixed block will drive the U-shaped plate to move, the movement of the U-shaped plate will drive the connecting plate to move, the movement of the connecting plate will drive the L-shaped connecting block to move, and the movement of the L-shaped connecting block will drive the pressing block to move inside the T-shaped water inlet groove, so as to generate pressure inside the T-shaped water inlet groove. When the second arc block moves upward, the second arc block 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 inclined, 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.

[0011] The present invention provides a switch cabinet with a lifting mechanism. It has the following beneficial effects:

[0012] (1) Through the setting of the heat dissipation device in the present invention, components such as the fan blade, the rotating shaft, the short rod, the looped rod, the connecting rod, the U-shaped rod, the chute, and the fan plate cooperate with each other, so that the U-shaped rod will move back and forth on the inner wall of the chute, thereby driving the fan plate to move back and forth along the outer wall of the fixed rod through the chute, so that the air flow blown out by the fan blade will bring the cool air on the surface of the fan plate into the interior of the switch cabinet main body, thereby enhancing the cooling effect on the electrical equipment; at the same time, through the cooperation of the fan plate, the U-shaped fins, the spherical block, and the abutting rod, when the arc-shaped end of the abutting rod does not abut against the spherical block, the spring will drive the abutting rod to reset through its own elastic force, and so on, so that the abutting rod realizes a reciprocating motion. The reciprocating motion of the abutting rod will drive the U-shaped fins to move back and forth, and the cool air inside the fan plate will be dissipated faster through the U-shaped fins.

[0013] (2) Through the setting of the dehumidifying device in the present invention, the cooperation of the dehumidifying block, the connecting rod, and the L-shaped rod enables the reciprocating movement of the connecting rod to drive the L-shaped rod to move back and forth, and the reciprocating movement of the L-shaped rod to drive the dehumidifying block to move back and forth, so as to increase the contact area of the dehumidifying block with the air and thus absorb the moisture in the air faster; at the same time, through the cooperation of the arc rod, the pressing rod, the L-shaped long rod, and the second arc block, the movement of the semi-arc rod will squeeze the spring between it and the protection frame, and the movement of the semi-arc rod will drive the pressing rod to squeeze the surface of the dehumidifying block, thereby avoiding the problem that the dehumidifying block is caked due to long-term exposure to the outside.

[0014] (3) With the arrangement of the pressurizing device in the present invention, through the cooperation of the fixed block, U-shaped plate, connecting plate, and L-shaped connecting block, the movement of the connecting plate of the pressing block drives the L-shaped connecting block to move, and the movement of the L-shaped connecting block drives the pressing block to move inside the T-shaped water inlet groove, thereby generating pressure inside the T-shaped water inlet groove and increasing the speed of rainwater entering the U-shaped pipe. At the same time, through the cooperation of the inclined surface of the inner wall of the T-shaped water inlet groove and the pressing block, when the pressing block moves upward, a gap will be formed between the pressing block and the inclined surface of the inner wall of the T-shaped water inlet groove, thus avoiding the problem that the rainwater on the inner wall of the U-shaped pipe is sucked out by the pressure when the pressing block moves upward.

Through the setting of the above structure, the air flow blown out by the fan blade 53 brings the cool air on the surface of the fan plate 510 into the switch cabinet main body 1, thereby enhancing the cooling effect on the electrical equipment.

[0026] A plurality of U-shaped fins 517 are slidably connected to the outer wall of the fan plate 510. The right tops of the plurality of U-shaped fins 517 are fixedly connected to the same contact rod 518. An arc plate 519 is fixedly connected to the side of the U-shaped block 58.

[0027] A dehumidifying device 6 for absorbing moisture in the air is provided at the top of the connecting rod 56. The dehumidifying device 6 includes an L-shaped rod 61. The bottom of the L-shaped rod 61 is fixedly connected to the top of the connecting rod 56. The end of the L-shaped rod 61 away from the connecting rod 56 is fixedly connected to a dehumidifying block 62. A track block for moving the dehumidifying block 62 is fixedly connected to the top of the protection frame 51. Through the setting of the above structure, the back-and-forth movement of the L-shaped rod 61 will drive the dehumidifying block 62 to move back and forth, so as to increase the contact area of the dehumidifying block 62 with the air, and thus absorb the moisture in the air faster.

[0028] An arc block one 63 is fixedly connected to the top of the return-shaped rod 55. A T-shaped rod 64 is fixedly connected to the top inner wall of the protection frame 51. A semi-arc rod 65 is slidably mounted on the outer wall of the T-shaped rod 64. A plurality of pressing rods 66 are fixedly connected to the top of the semi-arc rod 65. An L-shaped long rod 67 is fixedly connected to the outer wall of the semi-arc rod 65. The end of the L-shaped long rod 67 away from the semi-arc rod 65 is fixedly connected to an arc block two 68. A spring is provided between the semi-arc rod 65 and the protection frame 51. The arc block two 68 is located on the displacement track of the arc block one 63. The dehumidifying block 62 is located on the displacement track of the plurality of pressing rods 66. Through the setting of the above structure, the movement of the semi-arc rod 65 will drive the pressing rods 66 to squeeze the surface of the dehumidifying block 62, thus avoiding the problem that the dehumidifying block 62 is caked due to long-term exposure to the outside.

[0029] When in use, during rain, rainwater will flow through the T-shaped water inlet groove 512 into the U-shaped pipe 513, and then enter the water storage tank 511 inside the fan plate 510 through the hose 514 from the U-shaped pipe 513, and then flow out from the water outlet pipe on the side of the water storage tank 511. Thus, the fan plate 510 is kept in a cool state by the flow of rainwater. Then, the motor 52 is started. The output shaft of the motor 52 will cause the rotating shaft 521 to rotate. The rotation of the rotating shaft 521 will drive the fan blades 53 to rotate, thereby cooling the electrical equipment inside the switch cabinet. At the same time, the rotation of the rotating shaft 521 will drive the short rod 54 to rotate. The rotation of the short rod 54 will cause the looped rod 55 to move back and forth along the inner wall of the protection frame 51. The back-and-forth movement of the looped rod 55 will drive the connecting rod 56 to move back and forth. The back-and-forth movement of the connecting rod 56 will drive the long block 57 to move back and forth. The back-and-forth movement of the long block 57 will drive the U-shaped rod 516 to move back and forth. The U-shaped rod 516 will move back and forth along the inner wall of the chute 515, thereby driving the fan plate 510 to move back and forth along the outer wall of the fixed rod 59 through the chute 515, so that the airflow blown out by the fan blades 53 will bring the cool air on the surface of the fan plate 510 into the interior of the switch cabinet body 1, thereby enhancing the cooling effect on the electrical equipment. At the same time, the back-and-forth movement of the fan plate 510 will drive the U-shaped fin 517 to move. The movement of the U-shaped fin 517 will drive the contact rod 518 to move. The movement of the contact rod 518 will cause the arc-shaped end of it to contact the ball block 520, so that the contact rod 518 will compress the spring at its end away from the ball block 520. When the arc-shaped end of the contact rod 518 does not contact the ball block 520, the spring will drive the contact rod 518 to reset through its own elastic force. So on and so forth, thus enabling the contact rod 518 to achieve a reciprocating motion. The reciprocating motion of the contact rod 518 will drive the U-shaped fin 517 to move back and forth, and the cool air inside the fan plate 510 will be dissipated faster through the U-shaped fin 517.

[0030] When the external air flows into the switch cabinet main body 1 through the fan blade 53, the dehumidifying block 62 will absorb the moisture in the air. At the same time, the reciprocating movement of the connecting rod 56 will drive the L-shaped rod 61 to move back and forth. The reciprocating movement of the L-shaped rod 61 will drive the dehumidifying block 62 to move back and forth, so as to increase the contact area between the dehumidifying block 62 and the air, and thus absorb the moisture in the air faster. At the same time, the reciprocating movement of the return-shaped rod 55 will drive the first arc block 63 to move back and forth. The movement of the first arc block 63 will contact the second arc block 68, so that the second arc block 68 moves upward. The movement of the second arc block 68 will drive the L-shaped long rod 67 to move. The movement of the L-shaped long rod 67 will drive the semi-circular arc rod 65 to move. The movement of the semi-circular arc rod 65 will squeeze the spring between it and the protection frame 51. The movement of the semi-circular arc rod 65 will drive the pressing rod 66 to squeeze the surface of the dehumidifying block 62, thus avoiding the problem that the dehumidifying block 62 is caked due to long-term exposure to the outside. When the movement of the first arc block 63 does not contact the second arc block 68, the spring will drive the semi-circular arc rod 65, the pressing rod 66, the L-shaped long rod 67 and the second arc block 68 to reset through its own elastic force.

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

[0032] The pressurizing device 7 includes two fixing blocks 71. The bottoms of the two fixing blocks 71 are fixedly connected to the top of the second arc block 68. The tops of the two fixing blocks 71 are fixedly connected with the same U-shaped plate 72. The top of the U-shaped plate 72 is fixedly connected with a connecting plate 73. Both the left and right sides of the connecting plate 73 are fixedly connected with L-shaped connecting blocks 74. The bottoms of the two L-shaped connecting blocks 74 are fixedly connected with pressing blocks 75 around. The pressing blocks 75 are slidably connected to the inner wall of the T-shaped water inlet groove 512. Through the setting of the above structure, 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, so as to generate pressure inside the T-shaped water inlet groove 512, increase the speed of rainwater entering the U-shaped pipe 513. At the same time, when the pressing block 75 moves upward, there will be a gap between it and the inclined surface of the inner wall of the T-shaped water inlet groove 512, thus avoiding the problem that the rainwater on the inner wall of the U-shaped pipe 513 is sucked out by the pressure when the pressing block 75 moves upward.

[0033] During use, when the second arc-shaped block 68 is reset, the second arc-shaped block 68 drives the fixed block 71 to move downward. The movement of the fixed block 71 drives the U-shaped plate 72 to move. The movement of the U-shaped plate 72 drives the connecting plate 73 to move. The movement of the connecting plate 73 drives the L-shaped connecting block 74 to move. The movement of the L-shaped connecting block 74 drives 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 and increasing the speed of rainwater entering the U-shaped pipe 513. When the second arc-shaped block 68 moves upward, the second arc-shaped block 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. Since the inner wall of the T-shaped water inlet groove 512 in contact with the pressing block 75 is provided with an inclined surface, a gap will appear between the pressing block 75 and the inclined surface of the inner wall of the T-shaped water inlet groove 512 when the pressing block 75 moves upward, thus avoiding the problem that the rainwater on the inner wall of the U-shaped pipe 513 is sucked out by the pressure when the pressing block 75 moves upward.
