[0002] With the rapid development of communication technology, the stability and reliability of the communication power supply cabinet, as an important part of the communication infrastructure, play a crucial role in ensuring the normal operation of the communication network. Since a large number of electronic devices, such as environmental monitoring devices, data remote reading devices, remote visualization devices, and storage batteries, are integrated inside the power supply cabinet, these devices will generate a large amount of heat during operation. If the heat dissipation is poor, it will lead to a decrease in device performance, and even cause failure.

[0003] In view of the above problems, some existing technologies can improve the heat dissipation performance of the cabinet body. For example, the patent with the publication number CN211605858U mainly uses a heat dissipation motor to drive a heat dissipation fan to generate air flow, so that cold air enters the cabinet body from the air inlet, and is discharged from the cabinet body through the dust screen and the heat dissipation port along with the air flow generated by the heat dissipation fan, thereby achieving the purpose of heat dissipation. However, the technical solution has the following disadvantages: it cannot dehumidify the air entering the cabinet body through the air hole. When it is a rainy day outside, the environmental humidity is high, and the air entering the cabinet body contains a large amount of water, which can damage the electronic components in the cabinet body, and even cause the entire power grid to malfunction. Therefore, the present application provides a communication power supply cabinet convenient for heat dissipation, which can automatically dehumidify the air entering the cabinet body without affecting the heat dissipation of the cabinet body.

[0020] In one case of the embodiment, the driving assembly 13 includes a motor and an encoder connected with the motor, the encoder is connected with the travel switch 12, of course, the driving assembly 13 can also be selected from other structural components capable of realizing intermittent rotation, which is not specifically limited here; the positioning disc 7 and the rotating wheel 6 are detachably connected, which can be assembled by buckling or through bolt connection, which is not specifically limited here; the elastic member 11 can be selected from the spring shown in FIG. 5, and can also be replaced by other elastic components such as a silica gel column and a spring sheet, which is not specifically limited in the embodiment; the pressure pump, the travel switch 12 and the driving assembly 13 are connected with an external controller, the pressure pump, the travel switch 12 and the external controller are prior art, and the present application does not improve them, therefore, the specific mechanical structure and circuit structure of them do not need to be disclosed, and the integrity of the present application is not affected.

One end of the gas collecting pipe (26) on the drying position is connected with the air outlet hole group, and the other end is in abutment with the rotating wheel (6) and is in sliding fit with the rotating wheel (6). The two gas collecting pipes (26) are coaxially arranged with the air inlet pipe (4) and the exhaust pipe (5).

4. The communication power supply cabinet of claim 3, wherein, The dehumidification position and the drying position are symmetrically arranged, and the position between the dehumidification position and the drying position on the box (3) is provided with a pressing position. The pressing position is aligned with the dehumidification cotton (10) on one frame (8) each time the rotating wheel (6) stops rotating. The pressing position is provided with a pressing assembly.

5. The communication power supply cabinet of claim 3, wherein, ​ 6. The communication power cabinet of claim 5, wherein, The lifting plate (9) is fixed with a U-shaped frame (14) for mounting the dehumidification cotton (10), and the open end of the U-shaped frame (14) is connected with the lifting plate (9), the open end of the U-shaped frame (14) is slidingly installed with a movable rod (15), and the movable rod (15) is fixed with a second magnetic member (17), the end of the U-shaped frame (14) away from the movable rod (15) is fixed with a first magnetic member (16), and the magnetism of the first magnetic member (16) repels the magnetism of the second magnetic member (17), and the movable rod (15) is fixed with a fixed column (18); when the frame (8) rotates to the extrusion position, the fixed column (18) triggers the extrusion assembly to extrude the dehumidification cotton (10).

7. The communication power cabinet facilitating heat dissipation of claim 6, wherein, The air inlet pipe (4) and the air outlet pipe (5) are both hinged with a closing plate (19), and the closing plate (19) is elastically connected with the pipe wall of the air inlet pipe (4) and the air outlet pipe (5), and the position of the closing plate (19) interferes with the movement path of the fixed column (18).

8. The communication power cabinet facilitating heat dissipation of claim 6, wherein, The extrusion assembly comprises a push plate (22) slidingly installed on the box body (3) and a push column (25) fixed on the positioning disc (7), the push plate (22) is elastically connected with the box body (3), and the push plate (22) is connected with the wedge block (24) through the connecting rod (23), the position of the wedge block (24) interferes with the movement path of the push column (25); when the push column (25) rotates with the positioning disc (7) to contact the wedge block (24), the push plate (22) abuts against the fixed column (18), and then the push column (25) continues to rotate with the positioning disc (7), the push column (25) moves along the inclined surface of the wedge block (24) and pushes the wedge block (24) to vertically translate, and the push plate (22) synchronously vertically translates, in this process, the fixed column (18) is blocked and cannot continue to horizontally move, the relative sliding between the movable rod (15) and the U-shaped frame (14) occurs, and the movable rod (15) moves to the direction close to the first magnetic member (16), and the dehumidification cotton (10) is extruded and folded.

9. The communication power cabinet facilitating heat dissipation of claim 5, wherein, The box body (3) is provided with a collection box (20), and the extrusion position is arranged in the collection box (20), a sealing member is arranged at the connection between the collection box (20) and the box body (3), the collection box (20) is connected with the water cooling pipe in the cabinet body (1) through a connecting pipe (21), and a one-way valve is arranged on the connecting pipe (21).
