In this embodiment, a moisture-proof protection device for mining electrical equipment is provided, and referring to fig. 1 to 5, the moisture-proof protection device for mining electrical equipment includes: a protective box 1, a dehumidification box 4, a capillary tube 6 and a solid moisture absorbent 7.

As shown in fig. 1 and 2, the protection box 1 is a rectangular casing, heat dissipation holes 3 are formed in two sides of the protection box, a box door 2 is hinged to the front end of the protection box, and electrical equipment can be accommodated in the box body. Be equipped with handle 201 on chamber door 2, the periphery of handle 201 is equipped with anti-skidding line, through setting up handle 201 for the staff is more convenient when opening chamber door 2, and sets up anti-skidding line, makes the staff difficult emergence landing when operating handle 201. Fixedly connected with hasp 202 between the outer end of chamber door 2 and the body of guard box 1, through setting up hasp 202, make chamber door 2 be difficult for opening when meetting the weather of wind and rain, avoid external rainwater to get into the inside of chamber door 2.

The dehumidifying box 4 is also a casing embedded in the heat dissipating holes 3, and a partition plate 8 is disposed in the dehumidifying box 4 to divide the internal space into a first cavity 401 and a second cavity 402 which are distributed vertically. The two side walls of the first cavity 401 are provided with adsorption holes 5 communicating the inside and the outside of the protection box 1, and heat generated inside the protection box 1 can be released to the outside through the adsorption holes 5. A capillary tube 6 is further arranged in the adsorption hole 5, a solid desiccant 7 is arranged in the first cavity 401, a water seepage hole 9 is arranged on the partition plate 8, and a water drainage hole 10 is arranged at the bottom of the second cavity 402. Further, the protective box 1 is provided with a drain groove 11 communicating with the drain hole 10. The solid moisture absorbent 7 can be placed in the first cavity 401 through the adsorption hole 5, or a through hole with a rubber plug can be arranged on the partition plate 8, and the solid moisture absorbent 7 is placed in the first cavity 401 through the drainage hole 10 and the through hole.

In the using process, when the external humid air enters the protection box 1 through the dehumidification box 4, firstly, part of moisture is absorbed by the capillary action of the capillary tube 6 and flows downwards into the second cavity 402, and then the moisture in the air is absorbed by the solid moisture absorbent 7, so that the dry air enters the protection box 1, and the electrical equipment in the protection box is not easily affected with damp. After the solid moisture absorbent 7 absorbs a large amount of moisture, air is blown into the dehumidifying case 4 through the adsorption holes 5 inside the protective case 1, whereby the moisture in the solid moisture absorbent 7 can be reduced.

In addition, a dust screen 1101 is provided at the outer end of the drain tank 11, and the surface of the dust screen 1101 is coated with a rust preventive paint. By arranging the dustproof net 1101, mosquitoes and dust are not easy to enter the drainage groove 11, and the drainage groove 11 can be prevented from being blocked; by coating the antirust paint, the drainage channel 11 is not easy to rust when being used for a long time, and the service life of the drainage channel can be prolonged.

In addition, the upper end of the protection box 1 is fixedly connected with a reverse V-shaped water baffle 101, and two sides of the water baffle 101 are inclined planes extending to the outer end of the protection box 1. Through the arrangement of the water baffle 101, the water baffle 101 can isolate rainwater in rainy weather, so that the rainwater is not easy to permeate into the protection box 1; the two sides of the water baffle plate 101 are obliquely arranged, so that rainwater is not easy to accumulate at the upper end of the protective box 1, and the possibility of rainwater infiltration is further reduced.

In addition, a moisture-proof plate 102 is fixedly connected to the lower end of the protection box 1, and the moisture-proof plate 102 is made of a moisture-proof material, such as plastic, metal, and the like. Since the protection box 1 is in a mine for a long time and the ground is relatively wet, the moisture on the ground of the mine can be isolated by arranging the moisture-proof plate 102 made of the moisture-proof material, so that the protection box 1 is not easily wetted.

Compared with the prior art, the utility model discloses can realize when there is moist air to enter into the inside of guard box 1 from louvre 3, absorb moisture in the moist air to make the air that gets into 1 inside of guard box keep dry, make the inside of guard box 1 difficult weing, ensure that electrical equipment is difficult for taking place to damage.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
