The operation is simple and convenient for the staff to use. At the same time, the setting of the convex plate 1102 protects the filter element 1103 in the embedded box 1101, so that external rainwater will not enter the embedded box 1101 through the gap between the embedded box 1101 and the closed screen plate 1201 at the top of the base 4 during the downward flow, effectively preventing water accumulation in the filter element 1103 and ensuring the protective filtering effect of the filter element 1103.

[0034] Example 2

[0035] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , and on the basis of Example 1, it is further obtained that the fixing mechanism 2 includes a reset component 21, a moving component 22 and a positioning component 23, the reset component 21 is arranged on the left and right sides of the distribution cabinet body 3, the moving component 22 is arranged on the top of the reset component 21, and the positioning component 23 is arranged on the inner side of the moving component 22.

[0036] The reset assembly 21 includes a fixed cylinder 2101, which is fixedly connected to the left and right sides of the distribution cabinet body 3 and is located below the fixed plate 1301. A slide cylinder 2102 is slidably connected inside the fixed cylinder 2101, and a compression spring 2103 is fixedly connected inside the slide cylinder 2102. A lever 2104 is fixedly connected to the bottom of the slide cylinder 2102, and the lever 2104 is slidably connected to the bottom of the fixed cylinder 2101. The moving assembly 22 includes a moving slide bar 2201, which is fixedly connected to the top of the slide bar 2102, and the moving slide bar 2201 is slidably connected to the top of the fixed cylinder 2101. The top of the moving slide bar 2201 is fixedly connected to the clamping rod 2202. The positioning assembly 23 includes a sleeve 2301, which is sleeved on the outer ring of the clamping rod 2202. The outer ring of the sleeve 2301 is fixedly connected to a fixed fin 2302, and the fixed fin 2302 is fixedly connected to the outside of the fixed plate 1301.

[0037] Furthermore: the staff only needs to move the lever 2104 outward to drive the clamping rod 2202 outward to release the positioning of the fixed plate 1301, so that the staff can quickly complete the up and down movement of the closed screen plate 1201. The operation is simple and convenient for the staff to use. At the same time, the slide cylinder 2102 drives the clamping rod 2202 to maintain the inward movement force by moving the slide rod 2201 under the action of the compression spring 2103 in the absence of external force, so that the clamping rod 2202 can maintain the positioning of the closed screen plate 1201 without external interference, so that the closed screen plate 1201 can always maintain protection for the filter element 1103.

[0038] During actual operation, when this device is used, when the temperature inside the power distribution cabinet body 3 rises, the control element 33 controls the refrigeration device 32 to start and cool down the temperature inside the power distribution cabinet body 3. When the temperature inside the power distribution cabinet body 3 is too low, the control element 33 controls the refrigeration device 32 to shut down and then starts the heating device 31 to heat up the temperature inside the power distribution cabinet body 3, completing the control of the temperature inside the power distribution cabinet body 3, so that the internal temperature of the power distribution cabinet body 3 can be kept constant when in use. When the heating device 31 and the refrigeration device 32 control the temperature inside the power distribution cabinet body 3, the filter element 1103 is arranged in the embedded box 1101 to filter the air entering the power distribution cabinet body 3 for interaction, so that dust and water vapor in the external air cannot enter the power distribution cabinet body 3 and affect the heating device 31 and the refrigeration device 32;

[0039] When the filter element 1103 needs to be replaced, the staff first toggles the levers 2104 on the front and rear sides to move outward synchronously. The lever 2104 moves through the slide cylinder 2102 and the movable slide bar 2201 to drive the clamping rods 2202 on the front and rear sides to move outward synchronously. The clamping rod 2202 moves outward to disengage from the connection with the sleeve 2301 to release the positioning of the closed screen plate 1201. After that, the staff can pull the fixed plate 1301 upward to drive the closed screen plate 1201 to move upward. The closed screen plate 1201 moves upward to the position above the embedded box 1101. After that, the staff can replace the filter element 1103 in the embedded box 1101. After 103 is replaced, the staff first moves the levers 2104 on the front and rear sides outward, and then pulls the fixed plate 1301 downward to drive the closed screen plate 1201 to move downward until the bottom of the closed screen plate 1201 is in contact with the top of the base 4, and then releases the movement of the levers 2104 on the front and rear sides. At this time, the slide 2102 drives the clamping rod 2202 to move inward by moving the slide rod 2201 under the action of the compression spring 2103, and the clamping rods 2202 on the front and rear sides move inward and are clamped in the sleeve 2301. At this time, the positioning process of the closed screen plate 1201 is completed, and the replacement process of the filter element 1103 is completed.
