[0008] According to the above technical scheme, the heat dissipation device includes a cooling fan, a rotating rod, a rotating disk, a hollow frame, a connecting rod, a counterweight, a sealing plate and an extrusion rod. The two extrusion rods move away from each other to drive the sealing plate to rotate to release the seal of the cabinet and improve the heat dissipation speed of the power cabinet.

The displacement rod moves upward and hits the knocking frame to generate vibration. The vibration of the knocking frame drives the heat sink to resonate together. The vibration can help vibrate away the accumulated dust and dirt in the heat sink and clean the debris on the surface of the heat sink, thereby improving the heat conduction efficiency.

[0012] According to the above technical scheme, the disassembly device includes a long rod, a short rod, a segmented rod, a rectangular block, a rotating block and a limit block.

[0013] According to the above technical solution, a No. 5 spring is arranged between the segmented rod and the placement frame, a No. 6 spring is arranged between the rotating block and the rectangular block, and the rotating block is in contact with the limit block.

[0014] The present invention provides a power cabinet that facilitates dehumidification and heat dissipation. It has the following beneficial effects:

[0015] (1) The power cabinet that facilitates dehumidification and heat dissipation forms a limiter through the sliding cylinder and the dehumidification hole so that the dehumidification plate is fixed on the surface of the dehumidification frame. When the dehumidification plate needs to be replaced, the hollow cylinder is manually pulled upward to make the spring plate move to squeeze the dehumidification plate and pop out the dehumidification plate for replacement. Timely replacement of the dehumidification plate can effectively protect the electrical equipment in the power cabinet from humidity and corrosion. At the same time, the easily replaceable dehumidification plate improves the maintainability of the entire dehumidification device. The components of the dehumidification device can be more easily replaced, which helps to ensure that the dehumidification device maintains good performance during long-term operation.

[0016] (2) The power cabinet that facilitates dehumidification and heat dissipation, by moving the turntable to contact and squeeze the two extrusion rods, the two extrusion rods move away from each other, the two extrusion rods move away from each other to drive the sealing plate to rotate to release the seal on the cabinet body and improve the heat dissipation speed of the power cabinet. By releasing the seal on the cabinet body, the air inside and outside the power cabinet can circulate more freely, which helps to increase the inflow of fresh air and improve the air circulation efficiency, thereby more effectively removing the heat generated inside the power cabinet.

[0017] (3) The power cabinet that facilitates dehumidification and heat dissipation, through the scraper rod moving to contact the heat dissipation slot and rotating at the same time, scrapes and cleans the heat dissipation slot. Dust and dirt on the surface of the heat dissipation slot will affect the heat conduction and heat dissipation efficiency. Through scraping and cleaning, the heat dissipation efficiency of the device can be effectively improved, making it more effective in dissipating heat. At the same time, the displacement rod moves upward to hit the knocking frame to generate vibration. The vibration of the knocking frame drives the heat dissipation slot to resonate together. The vibration can help shake off the dust and dirt in the heat dissipation slot and clean the debris on the surface of the heat dissipation place, thereby improving the heat conduction efficiency.

[0018] (4) When the dehumidification and heat dissipation power cabinet is needed to replace the dehumidification plate of the power cabinet, the segmented rod needs to be manually rotated first. The segmented rod is rotated to release the limit on the short rod. The limit to prevent accidental touch is to prevent the dehumidification plate from accidentally popping out due to misoperation. However, when the dehumidification plate needs to be replaced, removing this restriction can avoid the occurrence of misoperation and reduce the damage to the device caused by misoperation. At the same time, the short rod moves downward to reset and contact with the rotating block. At this time, the rotating block is free to rotate without being limited by the limit block. The free rotation of the rotating block allows the long rod and the short rod to be automatically reset. The automatic reset reduces the need for manual intervention without waiting for manual intervention, reducing the burden on operators and alleviating the workload of maintenance and management.

[0037] A knocking frame 44 is fixedly installed on the inner wall of the cabinet 1, and a displacement rod 45 is slidably installed on the surface of the knocking frame 44. A downward pressure rod 46 is fixedly installed on the top of the displacement rod 45. A No. 4 spring is arranged between the displacement rod 45 and the knocking frame 44. The displacement rod 45 moves upward to hit the knocking frame 44 to generate vibration. The vibration of the knocking frame 44 drives the heat sink to resonate together.

[0039] A No. 5 spring is arranged between the segmented rod 53 and the placement frame 22, a No. 6 spring is arranged between the rotating block 55 and the rectangular block 54, and the rotating block 55 is in contact with the limit block 56. The No. 5 spring can drive the segmented rod 53 to reset, and the No. 6 spring can drive the rotating block 55 to reset.

[0041] When the dehumidifier plate 24 of the power cabinet needs to be replaced, the segmented rod 53 needs to be manually rotated first. After the segmented rod 53 is rotated to release the limit on the short rod 52, the short rod 52 is manually pulled upward to move.

The two long rods 51 move toward each other and drive the hollow cylinder 23 and the sliding cylinder 25 to move upward to replace the dehumidifier plate 24. At the same time, when the long rod 51 and the short rod 52 are reset, the short rod 52 moves downward to reset and contact the rotating block 55. At this time, the rotating block 55 is free to rotate without being limited by the limit block 56. The free rotation of the rotating block 55 allows the long rod 51 and the short rod 52 to be automatically reset.
