Abstract
Description
Technical Field
[0001] This utility model relates to a self-dust-removing low-voltage distribution cabinet. Background Technology
[0002] Low-voltage switchgear is widely used in industrial and civil power systems for distributing electrical energy and controlling circuits. However, during long-term operation, dust easily accumulates inside the switchgear, which not only affects the heat dissipation efficiency of the equipment but may also lead to a decrease in the insulation performance of electrical components, and even cause safety accidents such as short circuits.
[0003] Existing low-voltage distribution cabinets are typically cleaned manually, which requires disassembling the cabinet's outer casing or some components. This process is cumbersome and time-consuming, especially in large distribution cabinets where cleaning becomes even more complex and inefficient. Furthermore, operators may come into contact with live parts, posing a risk of electric shock. Therefore, a self-cleaning low-voltage distribution cabinet is proposed. Utility Model Content

[0026] To address the problem of cumbersome and time-consuming manual cleaning of existing low-voltage distribution cabinets, this utility model provides a self-cleaning low-voltage distribution cabinet. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] Please see Figure 1-6 This utility model provides a self-dust-removing low-voltage distribution cabinet, including a low-voltage distribution cabinet body 1, a plurality of air inlet guide pipes 2 for connecting to dust cleaning air pipes are arranged on the back side of the low-voltage distribution cabinet body 1, and a set of smoke and dust discharge pipes 3 for connecting to suction pipes are arranged on the upper part of the low-voltage distribution cabinet body 1.
[0028] The bottom of the low-voltage distribution cabinet 1 is equipped with a dust collection box 4 for collecting dust. Inside the dust collection box 4 is a cleaning assembly 5 for dust discharge. The cleaning assembly 5 includes a drive motor 51 located at the bottom of the dust collection box 4. The output end of the drive motor 51 is connected to an outer bushing 53 via a screw 52. A scraper 54 is provided on the upper part of the outer bushing 53, and the outer periphery of the scraper 54 is arc-shaped. An internal thread 531 is formed on the inner wall of the outer bushing 53, and the internal thread 531 engages with the screw 52, allowing the screw 52 to move through the connection between the screw 52 and the outer bushing 53. A dust cover 55 is located inside the dust collection box 4, above the drive motor 51. The front end of the dust cover 55 has a receiving groove 551 for accommodating the scraper 54. The upper part of the dust cover 55 is inclined, and the height of the inclined surface gradually decreases from right to left, so that the dust on the dust cover 55 slides down the inclined surface into the dust collection box 4. The dust collection box 4 is provided with a guide groove 41, and the guide groove 41 cooperates with the outer bushing 53 so that the outer bushing 53 can move linearly inside the dust collection box 4 through the guide groove 41.
[0029] The dust removal air pipe blows away the dust inside the low-voltage distribution cabinet 1 through the air inlet guide pipe 2.
[0030] The tail end of the air inlet guide pipe 2 is connected to the low-voltage distribution cabinet 1 through the gas guide plate 6.
[0031] The low-voltage distribution cabinet 1 has a dust discharge outlet 11 at the tail end of the dust collection box 4, and a cover plate 12 is provided at the dust discharge outlet 11.
[0032] The working principle of the self-dust-removing low-voltage distribution cabinet provided by this utility model is as follows:
[0033] The air vents on the top of the low-voltage distribution cabinet 1 are sealed, and then compressed air or clean airflow is introduced into the interior of the low-voltage distribution cabinet 1 through the air inlet guide pipe 2 connected to the dust cleaning air pipe.
[0034] The end of the air intake guide pipe 2 is connected to the cabinet through the gas guide plate 6 to ensure that the airflow is evenly distributed in the cabinet and to avoid local airflow being too strong or too weak.
[0035] The airflow creates turbulence within the cabinet, blowing away dust adhering to the surface of electrical components and inside the cabinet, suspending it in the air. Simultaneously, an external negative pressure fan absorbs the suspended dust inside the low-voltage distribution cabinet 1 through the dust exhaust pipe 3, significantly reducing the dust level inside the low-voltage distribution cabinet 1.
[0036] The remaining dust will gradually settle into the dust collection box 4 at the bottom of the cabinet under gravity after being left to stand.
[0037] The sloping design of the dust cover 55 guides the dust to slide into the dust collection box 4, and then the drive motor 51 is started to drive the screw 52 to rotate.
[0038] The screw 52 engages with the internal thread 531 inside the outer bushing 53, causing the outer bushing 53 to move linearly along the guide groove 41, which in turn drives the scraper 54 to move within the dust collection box 4.
[0039] The scraper 54 adheres to the inner wall of the dust collection box 4, scraping the dust to one end of the dust collection box 4. The scraper 54 concentrates the dust to the dust discharge port 11 at the tail end of the dust collection box 4, and the dust is cleaned periodically by opening the cover 12.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
