The upper end face of the moisture-proof plate 3 is provided with four rectangular-section placing cavities 31 in parallel along the vertical direction, each placing cavity 31 is internally provided with a strip-shaped desiccant bag 311, and the filler in the desiccant bag 311 is activated carbon. A plurality of air holes 32 communicated with the outside are uniformly formed on the inner side wall of the placing cavity 31 far away from the cabinet door 2. The desiccant bag 311 absorbs the moisture in the cabinet 1 through the ventilation holes 32, thereby ensuring the normal operation of the electrical components in the cabinet 1.

Referring to fig. 2 and 3, the upper end and the lower end of the placing cavity 31 are both communicated with the outside, and chamfers 312 are arranged at the upper ends of two opposite inner side walls of the adjacent air holes 32 of the placing cavity 31. The chamfer 312 can increase the area of the upper opening of the placing cavity 31, thereby facilitating the rapid clamping of the desiccant packet 311 into the placing cavity 31.

Referring to fig. 2 and 3, a plurality of buffer strips 313 made of rubber are fixedly connected to the inner side wall of the placing cavity 31 at intervals along the vertical direction, and each buffer strip 313 is semicircular in cross section and tightly supports against the outer side wall of the desiccant packet 311. When the desiccant packet 311 is placed in the placement chamber 31 in the vertical direction, the buffer strip 313 can tightly push against the outer side wall of the desiccant packet 311, so that the falling speed of the desiccant packet 311 is reduced.

Referring to fig. 2, one side that the lower terminal surface of dampproof board 3 is close to cabinet door 2 articulates along self length direction has and is used for sealing the closing plate 4 that is the rectangle of placing chamber 31 lower extreme open-ended, and the expansion end of closing plate 4 passes through locating part 5 and can dismantle with dampproof board 3 and be connected. The locating part 5 includes the spacing 51 with closing plate 4 activity end fixed connection, and the lower extreme middle part fixedly connected with stopper 52 that dampproofing board 3 deviates from one side of cabinet door 2, and the both ends of spacing 51 articulate respectively has and are used for the spacing arm 53 of hugging closely with stopper 52 back of the body both sides mutually, all wears to be equipped with spacing bolt 54 on every spacing arm 53, and every spacing bolt 54 all with stopper 52 threaded connection. When the desiccant bag 311 is invalid, the two limit bolts 54 are screwed out of the limit blocks 52, and the sealing plate 4 is rotated to be in a vertical state, so that the desiccant bag 311 slides out of the lower end of the moisture-proof plate 3, and the desiccant bag 311 can be replaced by a new desiccant bag 311 conveniently.

Referring to fig. 2, each of the limit bolts 54 is sleeved with a spring washer 55, one end of the spring washer 55 tightly abuts against the limit arm 53, and the other end of the spring washer 55 tightly abuts against the nut of the limit bolt 54. After the limit bolt 54 is tightened, the spring washer 55 is pressed and deformed to tightly press the limit bolt 54, thereby reducing the possibility of loosening the limit bolt 54.

Referring to fig. 2, the ascending both sides that carry on the back of the body of dampproofing board 3 vertical side all follow self length direction fixedly connected with mounting bar 6, all wear to be equipped with the erection column 7 that the cross-section is the rectangle on every mounting bar 6, the one end and the cabinet door 2 inside wall fixed connection of erection column 7 along the horizontal direction setting and erection column 7, mounting groove 71 has been seted up to the up end that erection column 7 is close to the one end of cabinet door 2, the interpolation of mounting groove 71 is equipped with mounting plate 8, mounting plate 8 is hugged closely with mounting bar 6 towards one side of cabinet door 2. The installation piece 8 is pulled out from the installation groove 71, so that the moisture-proof plate 3 can be detached from the cabinet door 2, and the cleaning is facilitated.

Referring to fig. 2, an elastic pad 9 made of a silica gel material is fixedly connected to one side of the moisture-proof plate 3 facing the cabinet door 2. After the moisture-proof plate 3 is installed, the elastic pad 9 is extruded by the moisture-proof plate 3 to deform, and meanwhile, the elastic pad 9 can provide a jacking force for the moisture-proof plate 3 to limit the moisture-proof plate 3 to slide on the installation column 7; in addition, dampproofing board 3 receives can push up tight installation piece 8 behind the tight power of top to increase the pressure between installation piece 8 and the mounting groove 71 inside wall, and then reduce the unexpected possibility that breaks away from mounting groove 71 of installation piece 8, improve dampproofing board 3's installation fastness.

The implementation principle of the low-voltage switch cabinet in the embodiment of the application is as follows: the desiccant bag 311 is put into the placing cavity 31 from the upper end of the damp-proof plate 3, so that the water vapor in the cabinet body 1 can be absorbed; after the desiccant bag 311 is invalid, the limit bolt 54 is unscrewed, the sealing plate 4 is rotated to a vertical state, and the desiccant bag 311 slides out from the lower end of the moisture-proof plate 3 under the action of gravity, so that the desiccant bag 311 can be replaced with a new desiccant bag.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
