Description

A mobile power distribution cabinet Technical Field

[0001] This utility model relates to a movable cabinet, specifically a movable power distribution cabinet. Background Technology

[0002] Electrical control cabinets, such as low-voltage distribution cabinets, are mainly used to install electrical components such as terminal blocks, knife switches, air switches, fuses, voltmeters, ammeters, frequency meters, and wattmeters. They generally have a closed or semi-closed cabinet, inside which the electrical components are installed. To facilitate changing locations, some distribution cabinets are equipped with casters on the bottom, allowing the cabinet to move by rotating the casters. Once in position, a braking mechanism locks the casters to ensure the cabinet is stable on the ground. However, because the contact area between the casters and the bottom surface is relatively small, it is difficult to guarantee cabinet stability even after braking, especially when subjected to unintended external forces, which can easily cause tilting or displacement, posing a safety hazard.

[0003] On the other hand, since the electrical components inside the cabinet require ventilation and heat dissipation, ventilation holes are usually opened on the bottom side of the distribution cabinet. When the electrical components are working, outside air enters the cabinet through these ventilation holes and flows upward, exiting from the top of the cabinet, achieving the purpose of heat dissipation and cooling. During outdoor transportation in mining areas, due to the harsh environmental conditions, external dust can easily enter the cabinet through these ventilation holes, causing dust pollution to the electrical components and affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a mobile power distribution cabinet. First, after being moved into place, the cabinet is housed by raising the casters so that the lower end of the side wall panel of the cabinet contacts the ground, thereby further improving the stability of the cabinet. Second, the ventilation holes are sealed during the transfer process to prevent dust from entering the cabinet.

[0005] The technical solution of this utility model is as follows:

[0006] A mobile power distribution cabinet includes a rectangular cabinet body formed by four side panels (left, right, front, and rear). The cabinet body has a top plate with air vents at the top and casters at the bottom. The cabinet also includes a rectangular base plate whose four sides are respectively connected to the four side panels. The base plate is higher than the bottom of the side panels, and the space directly below the base plate serves as a storage space for the casters. A rectangular lifting plate is located below the base plate, and a rectangular sliding plate is fixedly connected to the left and right sides of the lifting plate. The sliding plates fit against the inner sides of the left and right side panels and can slide up and down along their inner surfaces. The casters are mounted on the underside of the lifting plate. A lifting motor is mounted on the base plate, and a lead screw is mounted on the lifting plate. The lifting motor is connected to a lead screw that cooperates with the lead screw.

[0007] Preferably, the front and rear sides of the lifting plate are in contact with the front and rear sidewalls, respectively.

[0008] Preferably, there are four casters; they are each connected to the bottom side of the lifting plate via a wheel frame.

[0009] Preferably, the base plate is provided with base plate ventilation holes; the left and right side panels are provided with side panel ventilation holes; the slide plate is provided with slide plate ventilation holes; when the casters are retracted, the side panel ventilation holes are connected to the slide plate ventilation holes on the same side; when the casters are lowered, the slide plate closes the side panel ventilation holes.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] During the cabinet transfer process, the casters extend downwards and contact the ground, while the lower ends of the cabinet side panels detach from the ground. A sliding plate seals the ventilation holes in the side panels, effectively preventing dust from entering the cabinet. After the cabinet is in place, the casters are retracted into the cabinet by lifting it up, with the lower ends of the side panels contacting the ground, further improving cabinet stability. The ventilation holes in the sliding plate are connected to those in the side panels, ensuring proper ventilation and cooling during electrical operation within the cabinet.

[0017] The present invention will now be described in detail with reference to the embodiments and accompanying drawings.

[0018] As shown in Figures 1, 2, and 3, an embodiment of the cabinet of this utility model includes a rectangular cabinet body formed by four side wall panels 1 on the left, right, front, and rear. A top plate with air vents is installed at the top of the cabinet body, and casters 5 are provided at the bottom. It also includes a rectangular base plate 7 with ventilation holes 71 machined into it, whose four sides are respectively connected to the four side wall panels 1. The base plate 7 is higher than the lower end of the side wall panels 1, and the space directly below the base plate 7 serves as the receiving space for the casters 5. The space directly above the base plate 7 serves as the installation space for electrical components.

[0019] Referring to Figure 4, a rectangular lifting plate 4 is provided below the base plate 7. The front and rear sides of the lifting plate 4 are in contact with the front and rear side panels 1, respectively. A rectangular sliding plate 3 is fixedly connected to the left and right sides, respectively. The sliding plate 3 fits against the inner side of the left and right side panels 1 and can slide up and down along the inner side of the left and right side panels 1. The casters 5 are installed on the lower side of the lifting plate 4.

[0020] Furthermore, there are four casters 5, which are connected to the bottom side of the lifting plate 4 via wheel frames.

[0021] A lifting motor 6 is installed on the underside of the base plate 7, and a lead screw nut (not shown in the attached diagram) is installed on the lifting plate 4. The power output shaft of the lifting motor 6 is connected to a lead screw 2 that mates with the lead screw nut via a coupling.

[0022] When the lifting motor 6 is working, it drives the lead screw 2 to rotate, and the lead screw 2 drives the lifting plate 4 to move up and down through the lead screw nut. When the lifting plate 4 rises, it stores the casters 5 in the space directly below the bottom plate 7, and the lower end of the side wall panel 1 contacts the ground. When the lifting plate 4 descends, it pushes the side wall panel 1 off the ground and makes the casters 5 contact the ground.

[0023] Furthermore, each of the left and right side panels 1 has a side panel ventilation hole 11. The sliding plate 3 has a sliding plate ventilation hole 31. When the casters 5 are retracted, the side panel ventilation hole 11 is connected to the sliding plate ventilation hole 31 on the same side, meaning that the center point of the side panel ventilation hole 11 and the center point of the sliding plate ventilation hole 31 on the same side are at approximately the same height. When the casters 5 are lowered, the sliding plate 3 closes the side panel ventilation hole 11 (as shown in Figure 1). During the operation of the electrical components inside the cabinet, external airflow flows sequentially through the side panel ventilation hole 11, the sliding plate ventilation hole 31, the space directly below the bottom plate 7, the bottom plate ventilation hole 71, the space directly above the bottom plate 7, and the air outlet of the top plate to achieve heat dissipation and cooling. During cabinet movement, this airflow is closed by the sliding plate 3 to prevent external dust from entering.
