Description

Technical Field

[0001] The utility model specifically relates to a DC power distribution cabinet with a dehumidification function. Background Art

[0002] A distribution cabinet is an electrical device used for power distribution and control. It is usually located at the end of the distribution system and is used to distribute electrical energy to various load locations. It is often used in situations where the load is relatively dispersed and there are fewer circuits. There are mainly the following types: power distribution cabinets, lighting distribution cabinets, metering cabinets, protective distribution cabinets, drawer-type distribution cabinets, and outdoor distribution cabinets. When choosing the type of distribution cabinet, you need to consider its purpose, installation environment, load characteristics, and required protection functions, and then choose a suitable distribution cabinet for use.

[0003] When the distribution cabinet is used outdoors, moisture in the environment will enter the interior of the cabinet with the air flow. If it is not removed in time, it will easily affect the service life of various components in the cabinet. However, the current distribution cabinet does not have a dehumidification function, so moisture stays inside the cabinet for a long time, causing damage to various components and posing a safety hazard.

[0004] Therefore, it is necessary to invent a DC distribution cabinet with dehumidification function to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-4 A DC power distribution cabinet with a dehumidification function is shown, comprising a cabinet body 1 and a dehumidification component arranged on one side of the cabinet body 1;

[0029] The dehumidification assembly includes an induced draft fan 2 installed in the side wall of the cabinet 1, a hood 3 arranged outside the induced draft fan 2 and connected to the outer wall of the cabinet 1, an air duct 4 installed at the outlet end of the hood 3, a cover 5 arranged at the outlet end of the air duct 4 and connected to the outer wall of the cabinet 1, a barrel 6 connected to the inner wall of the cover 5, and activated carbon particles 7 placed inside the barrel 6, which are used to absorb moisture transported to the barrel 6 by the air duct 4;

[0030] A heating and stirring assembly is also provided inside the barrel body 6, and the heating and stirring assembly includes a rotating rod 9 that passes through the bottom wall of the barrel body 6, a plurality of heating rods 10 distributed on the rotating rod 9, and a handle 11 installed at the bottom end of the rotating rod 9, which is used to keep the activated carbon particles 7 dry.

[0031] In one embodiment, a one-way valve 8 is installed at the inlet end of the air duct 4 . The setting of the one-way valve 8 can effectively prevent the moisture remaining in the air duct 4 from flowing back into the cabinet 1 .

[0032] In one embodiment, the heating rods 10 are evenly spaced in groups of three around the rotating rod 9, and at least two groups are arranged along the rotating rod 9 from top to bottom, thereby ensuring the stirring effect of the heating rods 10, so that the activated carbon particles 7 at various locations in the barrel body 6 can fully contact with the heat emitted by the heating rods 10, and then be quickly dried and regenerated.

[0033] In one embodiment, the barrel body 6 and the cover body 5 are configured to be threadedly connected, and an annular plate 12 is installed around the bottom of the barrel body 6. The barrel body 6 is driven to rotate by rotating the annular plate 12, so that the barrel body 6 can be quickly disassembled and assembled. A limit block 13 is installed on the top of the rotating rod 9 to limit the screw-in distance of the barrel body 6. That is, when the limit block 13 contacts the top wall of the cover body 5, the staff is prompted to stop rotating the annular plate 12. At this time, the barrel body 6 is reset. A positioning plate 14 is provided at the connection between the rotating rod 9 and the bottom wall of the barrel body 6 to ensure the stability of the rotating rod 9 during rotation.

[0034] The specific implementation mode is as follows: when the utility model is in use, due to the influence of a humid environment or weather, when it is necessary to remove moisture from the cabinet 1, the staff turns on the induced draft fan 2, and the air containing moisture in the cabinet 1, that is, moisture, is absorbed into the air hood 3 through the induced draft fan 2, and then enters the air duct 4 after passing through the one-way valve 8, and is then sprayed into the hood 5, that is, above the barrel 6. At this time, the activated carbon particles 7 in the barrel 6 will absorb the moisture in the air, realize the discharge of moisture in the cabinet 1, avoid the accumulation of moisture in the cabinet 1, so that the inside of the cabinet 1 can be kept dry, ensure the normal operation of each component in the cabinet 1, and ensure the safety of the electrical system;

[0035] Furthermore, after the activated carbon particles 7 have been used for a long time, the staff can rotate the annular plate 12 to drive the barrel body 6 to rotate, rotate the barrel body 6 out of the cover body 5, and then start the heating rod 10 to heat the activated carbon particles 7 in the barrel body 6, so as to drive the moisture adsorbed in the activated carbon particles 7 out of the pores of the activated carbon particles 7, that is, to evaporate the moisture in the activated carbon particles 7 to desaturate them, keep the activated carbon particles 7 dry, and make them still have strong adsorption capacity during subsequent use. When the heating rod 10 is heated, the handle 11 is turned to drive the rotating rod 9 to rotate, so that multiple heating rods 10 rotate in the barrel body 6, and then the activated carbon particles 7 in the barrel body 6 are stirred, so that the activated carbon particles 7 at various locations in the barrel body 6 can be fully in contact with the heat emitted by the heating rod 10, thereby ensuring the regeneration effect of the activated carbon particles 7;

[0036] When the activated carbon particles 7 are dried again, the staff aligns the top opening of the barrel body 6 with the bottom opening of the cover body 5, and rotates the annular plate 12 so that the barrel body 6 is screwed in along the inner wall of the cover body 5, and the barrel body 6 can be installed and reset to realize the recycling of the activated carbon particles 7;

[0037] This embodiment specifically solves the problem in the prior art that the current power distribution cabinet does not have a dehumidification function, causing moisture to stay inside the cabinet 1 for a long time, causing damage to various components and posing a safety hazard.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
