Description

Technical Field

[0001] This utility model relates to the field of power equipment maintenance, and in particular to a maintenance device for power equipment. Background Technology

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc. The maintenance of power equipment is very important for ensuring the normal operation of the equipment, extending its service life, improving safety and reducing the failure rate.

[0003] During operation, especially in outdoor environments, electrical equipment is prone to accumulating dust and pollutants, which may affect its heat dissipation, insulation, and other functions. Current maintenance devices mostly use fans to blow away dust, but the dust blown off can also fall onto other electrical equipment, resulting in poor maintenance effectiveness. Therefore, we propose a maintenance device for electrical equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a maintenance device for power equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A maintenance device for power equipment includes a housing, a base fixedly connected to the bottom surface of the housing, a cover on the top of the housing, an air intake sleeve fixedly connected to the outer surface of the housing, and an exhaust sleeve fixedly connected to the outer surface of the base. Both the air intake sleeve and the exhaust sleeve are threadedly connected to connectors. A dust suction pipe and an air blowing pipe are fixedly connected to the right ends of the two connectors, respectively. One end of the dust suction pipe is fixedly connected to a handheld dust suction hood, and one end of the air blowing pipe is fixedly connected to a handheld air nozzle. A fixing plate is fixedly connected to the inside of the housing, and a filter cylinder is fixedly connected to the bottom surface of the fixing plate. The filter cylinder contains a filter element, and the bottom surface of the filter cylinder has equally spaced exhaust holes. A negative pressure fan is mounted on the upper surface of the base.

[0007] In a further embodiment, the inner wall of the cover is threadedly connected to the outer surface of the top of the housing, and a handle is fixedly connected to the upper surface of the cover.

[0008] In a further embodiment, a control switch is installed on the outer surface of the cover, and the control switch is electrically connected to the negative pressure fan via a wire.

[0009] In a further embodiment, a bottom cover is mounted on the bottom surface of the base by screws, and two sets of casters are mounted on the bottom surface of the bottom cover.

[0010] In a further embodiment, the interior of the housing is provided with a connecting cover, the top of which is connected to the bottom of the filter cartridge.

[0011] In a further embodiment, the outer surface of the housing is provided with a display window, and the outer surfaces of the handheld vacuum cleaner cover and the handheld air nozzle are both covered with insulating sleeves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a housing and base to mount a negative pressure fan. Suction and exhaust connection sleeves are respectively installed on the housing and base. The exhaust connection sleeve connects to the blowing pipe and a handheld nozzle. Utilizing the exhaust effect of the negative pressure fan, the handheld nozzle can blow away dust from electrical equipment. The suction connection sleeve connects to the suction pipe and a handheld dust hood, which sucks the dust blown away by the nozzle into the housing. A filter cartridge is installed inside the housing, filtering the dust through its filter element. This solves the problem that current maintenance devices mostly use fans to blow away dust, but the blown dust can still fall onto other electrical equipment, resulting in poor maintenance effectiveness.
