[0023] Specifically, a fixed box 2 is fixedly arranged at the bottom end of the cabinet 1. A fixed cover 3 is fixedly arranged inside the fixed box 2. A plurality of air guide pipes 4 are fixedly arranged on both sides of the fixed cover 3, and the air guide pipes 4 are arranged in a "U" shape. Above the air guide pipes 4 is a fixed pipe 5, and the fixed pipe 5 is arranged inside the cabinet 1. A plurality of air holes 6 are arranged through the outer side wall of the fixed pipe 5. At the bottom end inside the fixed pipe 5 is a water-absorbing cotton 7. Above the water-absorbing cotton 7 is a pressing block 8. The top end of the pressing block 8 is fixedly provided with a connecting rod 9. The outer side wall of the bottom end of the fixed pipe 5 is provided with a strip-shaped groove 10 through which the connecting rod 9 passes through the inside of the strip-shaped groove 10. The outer side wall of the bottom end of the air guide pipe 4 is provided with a drain hole 11, and the arrangement of the drain hole 11 facilitates the discharge of water;

[0024] More specifically, positioning blocks 12 are fixedly arranged at both ends of the connecting rod 9. A lead screw groove 13 is arranged through the middle of the positioning block 12. A driving lead screw 14 is arranged through the inside of the lead screw groove 13. The bottom end of the driving lead screw 14 is fixedly provided with a synchronous motor 15, and the synchronous motor 15 is fixedly arranged inside the cabinet 1. A plurality of synchronous motors 15 can rotate synchronously to realize the synchronous extrusion of multiple groups of water-absorbing cotton 7;

[0025] Moreover, a through groove 16 is arranged through the inner side wall of the bottom end of the fixed box 2. The middle part of the lower surface of the fixed box 2 is fixedly provided with an air pump 17, and the input end of the air pump 17 passes through the inside of the fixed cover 3. The top end of the air guide pipe 4 is fixedly provided with a connecting seat 18, and the connecting seat 18 is fixedly connected to the bottom end of the fixed pipe 5 by bolts. A fixed frame 19 is fixedly arranged inside the connecting seat 18, and the fixed frame 19 is arranged below the water-absorbing cotton 7, and the fixed frame 19 can support the water-absorbing cotton 7;

[0026] Furthermore, an exhaust hood 20 is fixedly arranged at the top end of the cabinet 1. A plurality of exhaust grooves 21 are arranged on both sides of the exhaust hood 20. A dust-proof net 22 is arranged at the top end of the exhaust hood 22. The arrangement of the dust-proof net 22 can prevent external dust from entering the inside of the cabinet 1. A cabinet door 23 is arranged on the outer side of the cabinet body 1.

[0027] The working principle of the present utility model:

[0028] When the device is in use, capacitors and reactive power compensation components inside the cabinet 1 can realize the reactive power compensation of the power grid. During this process, the air pump 17 can extract external air and transport it into the fixed cover 3. The air passes through the fixed cover 3 and the air guide pipes 4 into the fixed pipe 5, and after passing through the water-absorbing cotton 7, it passes through the air holes 6 into the inside of the cabinet 1. After the air exchanges heat with the components inside the cabinet 1, it is discharged from the cabinet through the exhaust grooves 21 and the exhaust hood 20 at the top end of the cabinet. Thus, the heat dissipation of the components can be realized, and the arrangement of the water-absorbing cotton 7 can prevent water vapor in the external environment from entering the inside of the cabinet 1, thereby ensuring the stable operation of the components inside the cabinet 1;

[0029] When the water-absorbing cotton 7 is saturated with water absorption, the synchronous motor 15 can drive the transmission lead screw 14 to rotate. Since the transmission lead screw 14 cooperates with the lead screw groove 13, the position of the positioning block 12 can be adjusted. The positioning block 12 can drive the connecting rod 9 to move downward, and the connecting rod 9 drives the pressing block 8 to move downward. The pressing block 8 can squeeze the water-absorbing cotton 7, so that the water absorbed by the water-absorbing cotton 7 is squeezed out. After the water is squeezed out, it is discharged through the drain hole 11 at the bottom end of the air guide pipe 4. At this time, it can be avoided that the moisture-proof effect of the device is affected by the saturated water absorption of the water-absorbing cotton 7.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
