[0024] Such as Figures 1 to 4As shown in the figure, the present application provides a moisture-proof device for a high-voltage control cabinet, including a first housing 1 and a second housing 7 detachably connected to the first housing 1. The cross-section of the first housing 1 is T-shaped. The end of the first housing 1 close to the high-voltage control cabinet is the large-diameter end, and a plurality of mounting holes are provided thereon to mount the first housing 1 in the high-voltage control cabinet. Of course, a slot-like structure can also be provided at the bottom of the first housing 1, and the first housing 1 can be clamped on the guide rail in the high-voltage control cabinet by means of clamping.

[0025] A first mounting plate 607 and a second mounting plate 608 are installed on the inner wall of the second housing 7. The first mounting plate 607 and the second mounting plate 608 are arranged at intervals. The first mounting plate 607 is fixedly connected to the inner wall of the second housing 7, and the second mounting plate 608 is only in contact with the inner wall of the second housing 7. The second mounting plate 608 is connected to the first mounting plate 607 through a connecting structure 6, and a dehumidifying cotton 3 is arranged between the first mounting plate 607 and the second mounting plate 608.

[0026] The first housing 1 and the second housing 7 are detachably connected, which is convenient for removing the second housing 7 to replace the dehumidifying cotton 3. If the dehumidifying cotton 3 is installed in the first housing 1, due to the limited space in the high-voltage control cabinet, when removing the dehumidifying cotton 3 and installing a new dehumidifying cotton 3, the position is limited and the operation is not very convenient. In this embodiment, both the first housing 1 and the second housing 7 are provided with threaded joints 702 and are connected by means of threaded connection, so that no additional tools are required for the connection and disassembly between the first housing 1 and the second housing 7.

[0027] When the second housing 7 is rotated to be connected to or disassembled from the first housing 1, in order to prevent slipping, a plurality of anti-slip ridges 704 are provided on the outer periphery of the second housing 7.

[0028] A breathable structure is provided on the side of the second housing 7 away from the first housing 1. A plurality of ventilation holes can be provided on the second housing 7. Since there may be dust in the high-voltage control, in this embodiment, a dust-proof cover 5 is installed on the side of the second housing 7 away from the first housing 1. The dust-proof cover 5 can both breathe and block dust.

[0029] In order to dry the air in the high-voltage control cabinet, the gas should be inhaled into the moisture-proof device as much as possible and filtered for moisture through the dehumidifying cotton 3. Therefore, in the present application, a fan 2 is installed on the side of the first housing 1 away from the second housing 7. The fan 2 rotates to inhale the gas in the high-voltage control into the moisture-proof device. Since the fan 2 will generate noise during rotation, a sound-absorbing cotton 4 is installed in the second housing 7. The sound-absorbing cotton 4 is located between the dehumidifying cotton 3 and the dust-proof cover 5.

[0030] The dust cover 5 can be snap-fitted into the second housing 7 for easy replacement. Of course, other structures can also be used to install the dust cover 5 on the second housing 7. The first mounting plate 607 and the second mounting plate 608 are also provided with ventilation holes to facilitate gas circulation.

[0031] To prevent air from entering the moisture-proof structure through the gap between the first housing 1 and the second housing 7 without passing through the dehumidifying cotton 3, a gasket 703 is provided between the first housing 1 and the second housing 7.

[0032] The first mounting plate 607 can be fixedly installed on the inner wall of the second housing 7. The second mounting plate 608 is connected to the first mounting plate 607 through a connecting structure 6. The space between the first mounting plate 607 and the second mounting plate 608 is sufficient to place the dehumidifying cotton 3.

[0033] For convenience, the connecting structure 6 between the first mounting plate 607 and the second mounting plate 608 can be directly disassembled without using tools. Therefore, the first mounting plate 607 and the second mounting plate 608 of this application do not adopt a relatively simple bolt connection.

[0034] Specifically, the connecting structure 6 includes a fixed seat 601 and a mounting plug 602. The fixed seat 601 is arranged on the side of the first mounting plate 607 away from the second mounting plate 608. The fixed seat 601 is fixedly installed on the inner wall of the second housing 7. A groove is provided in the fixed seat 601. A fixed chuck 603 is arranged on the side of the mounting plug 602 close to the fixed seat 601. The fixed chuck 603 and the mounting plug 602 form a T shape. The fixed chuck 603 is located in the groove. A limiting component is arranged on the side wall of the groove for limiting the fixed chuck 603. The mounting plug 602 generally adopts a cylindrical rod.

[0035] After the fixed chuck 603 rotates a certain angle, it can pass through the limiting component. The fixed chuck 603 can rotate in the groove. The fixed chuck 603 can be circular, but notches should be provided on both sides of the circle, which is equivalent to designing a structure for the fixed chuck 603 to smoothly pass through the limiting component. After the fixed chuck 603 rotates a certain angle, the fixed chuck 603 is disengaged from the limiting component, and the fixed chuck 603 can slide out of the groove. As Figure 3 shown, when the fixed chuck 603 is stuck in the groove, the notches of the fixed chuck 603 are arranged front and back. The left and right sides of the fixed chuck 603 are in contact with the limiting component, and the fixed chuck 603 cannot come out of the groove. When the fixed chuck 603 rotates 90°, the notches of the fixed chuck 603 are arranged left and right, so that the fixed chuck 603 can slide out of the groove.

[0036] Of course, the fixed chuck 603 can also be set to an oval shape. The length dimension of the major axis of the fixed chuck 603 is greater than the distance between the limiting components on the inner wall of the fixed seat 601, and the length dimension of the minor axis of the fixed chuck 603 is less than the distance between the limiting components on the inner wall of the fixed seat 601. The minor axis section is equivalent to a notch provided on the fixed chuck 603.

[0037] The limiting components include a limiting spring 605 and a limiting chuck 604. One end of the limiting spring 605 is connected to the inner wall of the groove, and the other end is connected to the limiting chuck 604. When the limiting spring 605 is in its natural state, the limiting chuck 604 contacts the installation insert rod 602. The limiting chuck 604 can also be directly connected to the inner wall of the groove. However, in this case, the limiting chuck 604 is rigid and has no shrinkage, so the dimensional requirements for the limiting chuck 604 and the installation insert rod 602 are relatively high, otherwise they cannot be installed. When the limiting spring 605 is in its natural state, the limiting chuck 604 is located at the point where the installation insert rod 602 contacts the fixed chuck 603, thereby preventing the fixed chuck 603 from falling out of the groove.

[0038] The groove includes a first section and a second section. As Figure 3 shown, the upper part is the first section, and the lower part is the second section. The width of the first section is less than the width of the second section. The fixed chuck 603 is located in the first section, and the limiting spring 605 is located in the second section. The top of the fixed chuck 603 can contact the top of the first section or a certain space can be reserved. Because a rotating pull rod 606 is connected to the end of the installation insert rod 602 away from the fixed chuck 603, and the rotating pull rod 606 is rotatably connected to the second mounting plate 608. When it is necessary to rotate the connecting structure 6, the installation insert rod 602 can be pushed towards the groove side, so that the limiting chuck 604 is separated from the fixed chuck 603, and then the rotation is smoother, preventing interference when rotating while the limiting chuck 604 is in contact with the fixed chuck 603.

[0039] A compression spring can be installed at the connection between the rotating pull rod 606 and the installation insert rod 602. The rotating pull rod 606 and the installation insert rod 602 are hinged, that is, the rotating pull rod 606 and the installation insert rod 602 are in a straight line when in use and are at 90° when not rotating, which saves the volume of the entire moisture-proof device. A card slot can also be provided on the inner wall of the second housing 7. When the rotating pull rod 606 does not need to rotate, it can be stuck in the card slot.

[0040] The above embodiments are only illustrative of the principles and effects of the present utility model and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
