Description

Technical Field

[0001] The present invention belongs to the technical field of automatic cleaning of equipment in a power supply system, and in particular, relates to a self-cleaning device and method for a field power cabinet in a power grid system. Background Art

[0002] As the country's electricity consumption continues to increase, the expansion of power supply areas has led to an increasing number of outdoor power facilities. Due to various reasons, many lines and distribution boxes are located in remote areas. In order to ensure the safe operation of these areas, they must be inspected and maintained regularly. However, the outdoor environment is complex and changeable, and there is often bad weather that affects the normal activities of personnel. Therefore, the inspection work of staff becomes very cumbersome and time-consuming.

[0003] Existing outdoor power cabinets often only focus on the cleaning and heat dissipation inside the cabinet. When no one cleans the area around the cabinet for a long time, shrubs and weeds will grow, and even the shrubs and weeds will cover the outer shell of the cabinet. Once the internal components of the cabinet fail, maintenance personnel often cannot open the cabinet for inspection in the first time. It takes a lot of time just to clean the outer shrubs and weeds, which seriously affects the maintenance progress.

[0004] Therefore, it is urgent to develop a self-cleaning device and method for outdoor power cabinets in a power grid system. Summary of the invention

[0009] Preferably, the slide rail is dovetail-shaped or T-shaped, and a dovetail groove or T-shaped groove matching the slide rail is provided on a side of the slide seat close to the cabinet.

[0010] Preferably, the lifting assembly includes a lifting motor and a reciprocating screw, the lifting motor is fixed on the side wall of the cabinet, and the output shaft of the lifting motor is transmission-connected to the reciprocating screw, and the lower part of the sliding seat is provided with a threaded hole matching the reciprocating screw.

[0011] Preferably, a corrugated sleeve is connected between the lifting motor and the sliding seat, and the corrugated sleeve is sleeved on the outside of the reciprocating screw rod and does not interfere with the reciprocating screw rod.

[0012] Preferably, bearing seats are correspondingly provided at the upper and lower ends of the sliding seat, the two ends of the rotating shaft are rotatably connected to the two bearing seats respectively, and the upper end of the rotating shaft passes through the bearing seats at the corresponding ends and is transmission-connected to the driving element.

[0013] Preferably, the driving element is a servo motor, and the servo motor is fixed on a bearing seat at the upper end of the sliding seat, and the output shaft of the servo motor is drivingly connected to the rotating shaft.

[0014] Preferably, the cleaning assembly includes a plurality of horizontal swing arms evenly distributed along the height direction of the rotating shaft, the horizontal swing arm includes a first straight section, a second straight section and a curved section, the curved section is connected between the first straight section and the second straight section, and the first straight section is fixedly connected to the rotating shaft, when the cleaning assembly swings to the front side of the cabinet, the first straight section is parallel to the left and right walls of the cabinet, the second straight section is parallel to the cabinet door, and the curved section does not interfere with the cabinet.

[0015] Preferably, a plurality of vertically arranged cleaning rods are connected between the horizontal swing arms on each rotating shaft, the cross-sections of the horizontal swing arms and the cleaning rods are both triangular, and the cleaning rods and the horizontal swing arms are ground with blades on the side away from the cabinet.

[0016] The present invention also proposes a method for self-cleaning a field power cabinet in a power grid system, which adopts the above-mentioned field power cabinet self-cleaning device in the power grid system and includes the following steps:

[0017] S1. An alarm is arranged on the top of the cabinet, and the alarm, the reciprocating lifting mechanism and the reciprocating cleaning device are electrically connected to the PLC controller in the cabinet respectively;

[0023] The working principle of the present invention is that when the present application is working, the alarm serves to warn the staff or passers-by to prevent the device from suddenly starting up and causing harm to nearby personnel. After the reciprocating cleaning device is started, its cleaning component can move back and forth from the front of the cabinet door of the field power cabinet to both sides, so as to achieve the purpose of cleaning the bushes and weeds in front of the cabinet door. In order to prevent the bushes and weeds from accumulating on the cleaning component during the cleaning process, the reciprocating lifting mechanism drives the reciprocating cleaning device to move up and down to shake off the bushes, weeds and other debris on the cleaning component. The device can be set to start at a scheduled time according to environmental needs, thereby realizing the self-cleaning function of the field power cabinet, thereby avoiding the situation where the bushes or weeds in front of the field power cabinet door cannot be opened during use due to long-term lack of cleaning.

[0024] The beneficial effects of the present invention are as follows: the device of the present invention has a simple structure, convenient process operation, can be started regularly as needed, and can automatically clean weeds and shrubs in front of a field power cabinet door, thereby ensuring the maintainability of the field power cabinet when a fault occurs.
