A first sliding groove is provided on the inner wall of the switch cabinet 1, and the inner wall of the first sliding groove is slidably connected with a sliding bar 3116. The outer wall of the sliding bar 3116 is fixedly connected with a dehumidification frame 3117. The inner wall of the dehumidification frame 3117 is provided with a second sliding groove. The inner wall of the second sliding groove is fixedly connected with a sliding bar 3114, and the outer wall of the sliding bar 3114 is slidably connected with a sliding block 3113. The top of the sliding block 3113 is fixedly connected with a first spring 3115, and the end of the first spring 3115 away from the sliding block 3113 is fixedly connected to the top of the inner wall of the second sliding groove. The outer wall of the sliding block 3113 is fixedly connected with a moving plate 3118, and the top of the sliding block 3113 is fixedly connected with a connecting rod 3112, and the connecting rod 3112 moves through the top of the inner wall of the second sliding groove, and the end of the connecting rod 3112 away from the sliding block 3113 is fixedly connected with a force block 3111.

[0028] Furthermore, there are two fan blades 3110, which are distributed on the left and right sides of the switch cabinet 1 in a left-right symmetrical structure, thereby increasing the blowing range and allowing a large amount of air inside the switch cabinet 1 to be blown into the dehumidification frame 3117, thereby improving the dehumidification efficiency.

[0029] Furthermore, both the bottom end of the extrusion rod 319 and the top end of the force block 3111 are provided with inclined surfaces, and the outer walls of the inclined surfaces provided by the two are fitted together, so that when the force block 3111 is squeezed by the extrusion rod 319, the squeeze area is larger and the squeezing process is more stable.

[0033] The implementation principle of a high-voltage switch cabinet with a dehumidification effect in this embodiment is as follows: a dehumidifier is put into the dehumidification frame 3117. When dehumidification is performed, the motor 312 can be started, and its output end drives the first rotating rod 313 to rotate, thereby driving the transmission wheel 314 and the belt 315 to rotate, so that the belt 315 will drive the second rotating rod 316 to rotate, thereby driving the fan blade 3110 to rotate, and the air inside the switch cabinet 1 can be blown to the dehumidification frame 3117 through the fan blade 3110, and the air is dehumidified by the dehumidifier inside the dehumidification frame 3117. At the same time, the second rotating rod 316 drives the connecting rotating rod 318 and the extrusion rod 316 during the rotation process. 19 rotates, and when the squeezing rod 319 rotates, it will contact and squeeze the force block 3111, and the squeezed force block 3111 will drive the connecting rod 3112 and the slider 3113 to move downward, and then the slider 3113 drives the movable plate 3118 to move downward, and at the same time stretches the first spring 3115. When the squeezing rod 319 is away from the force block 3111, the first spring 3115 rebounds and drives the slider 3113 and the movable plate 3118 to move upward, and repeatedly drives the movable plate 3118 to vibrate up and down, and shakes the dehumidifier inside up and down to prevent caking due to moisture absorption, which affects the subsequent dehumidification effect.

[0034] When the dehumidifier absorbs moisture and is in a saturated state and needs to be replaced, the lever 323 can be pushed downward. At this time, the lever 323 will drive the slide column 322 to move downward, and at the same time squeeze and compress the second spring 321. At this time, the slide column 322 can drive the top card protrusion 324 to move downward, so that the card protrusion 324 is away from the inner wall of the card slot 325, and contacts the card connection between the card slot 325. Then, the dehumidifier frame 3117 is pulled to move on the inner wall of the first slide slot through the slide bar 3116, so that the dehumidifier frame 3117 can be pulled out, and then the dehumidifier inside can be replaced. After the replacement is completed, the dehumidifier frame 3117 is pushed back into the switch cabinet 1, so that the card slot 325 and the card protrusion 324 are engaged to complete the installation.
