Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, and more specifically, to a power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits. The motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] A patent document with publication number CN210111372U in the prior art provides an intelligent heat dissipation distribution cabinet. The device connects the cabinet door with a cooling fan so that when the cabinet door is closed, the cooling fan is inside the cabinet. The cooling fan can strengthen the convection between the high-temperature air inside the cabinet and the ambient air, thereby achieving cooling and heat dissipation inside the cabinet. By opening the cabinet door, the space around the air outlet frame becomes larger, which makes it convenient for staff to disassemble or repair the cooling fan, thereby improving convenience.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, dust will accumulate in the holes on the heat dissipation window, causing blockage that cannot be cleaned and transferred, thereby affecting the heat dissipation effect of the distribution cabinet; secondly, the wires of electrical equipment are easily scattered during the use of the device, which needs to be improved. In view of this, we propose a distribution cabinet. Utility Model Content

The utility model allows a worker to open the cabinet door 2 to install or repair the electrical equipment inside the distribution cabinet, and drives the reciprocating screw 501 to rotate through the motor 503, thereby driving the moving block 504 threadedly connected to the circumferential outer wall of the reciprocating screw 501 to move, and then drives the cleaning brush plate 505 to reciprocate up and down, so as to more conveniently clean the dust accumulated on the heat dissipation window 4 and prevent blockage that affects the heat dissipation function of the distribution cabinet.

[0029] Specifically, one side of the cleaning brush plate 505 is densely covered with bristles, and the bristles are in contact with the inner wall of the heat dissipation window 4. By cleaning the bristles on one side of the cleaning brush plate 505 in contact with the inner wall of the heat dissipation window 4, the dust accumulated on the heat dissipation windows 4 on both sides of the power distribution cabinet can be efficiently cleaned.

[0030] Furthermore, the wiring harness assembly 7 includes a positioning sleeve 701, a screw 702 is threadedly connected to the side wall of the positioning sleeve 701, a pressure plate 703 is fixedly provided on one side of the screw 702, and a knob 704 is fixedly provided on the other side of the screw 702. The screw 702 is rotated by turning the knob 704, so that the pressure plate 703 is moved to a desired position, and the pressure plate 703 and the positioning sleeve 701 squeeze the wires so that the wires are not easily scattered.

[0031] It is worth noting that the positioning sleeve 701 is a square up-and-down through-type structure, and the size of the pressing plate 703 matches the size of the inner cavity of the positioning sleeve 701. The positioning sleeve 701 with a square up-and-down through-type structure facilitates the wires to pass through for arrangement.

[0032] It is worth noting that a first handle 3 is fixedly provided on one side of the cabinet door 2, and drawers 8 are slidably connected to the cabinet body 1 through holes opened at the bottom of both sides, and a second handle 9 is fixedly provided on the side wall of the drawer 8. The first handle 3 is convenient for the staff to open and close the cabinet door 2, and the second handle 9 is convenient for the staff to pull the drawer 8.

[0033] In addition, the top of the drawer 8 is open, and a pad is provided at the bottom of the inner cavity of the drawer 8. The dust and debris cleaned by the cleaning brush plate 505 when the power distribution cabinet is radiated is collected through the top of the drawer 8 being open, and the drawer 8 is conveniently cleaned by replacing the pad.

[0034] In addition, the circuits, electronic components and modules involved in the utility model are all prior art, and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and method.

[0035] The device or equipment models involved in this article are as follows:

[0036] The model of motor 503 may be: Y90S-2.

[0037] Working principle: When the device is needed to use the distribution cabinet, the staff pulls the first handle 3 to open the cabinet door 2 to install or repair the electrical equipment inside the distribution cabinet, and puts the wires of the electrical equipment through the positioning sleeve 701 for arrangement. Turning the knob 704 drives the screw 702 to rotate, so that the pressure plate 703 moves to squeeze the wires to prevent them from being scattered. Turning on the motor 503 drives the reciprocating screw 501 to rotate, thereby driving the moving block 504 threadedly connected to the outer wall of the circumference of the reciprocating screw 501 to move, and then drives the cleaning brush plate 505 to reciprocate up and down. The bristles on one side of the cleaning brush plate 505 are in contact with the inner wall of the heat dissipation window 4, which can efficiently clean the dust accumulated on the heat dissipation windows 4 on both sides of the distribution cabinet to prevent blockage and affect the heat dissipation function of the distribution cabinet. The drawer 8 with an opening on the top collects the dust and debris cleaned by the cleaning brush plate 505 when the distribution cabinet is dissipating heat. After cleaning, the staff pulls the second handle 9 to pull out the drawer 8, replaces the pad paper for cleaning.
