Description
Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, and specifically relates to an inspection robot. Background Technology
[0002] As the core hub of a wind power generation system, a wind power substation houses high-voltage electrical equipment such as transformers, switchgear, busbars, and control and protection devices. These devices have extremely high requirements for the cleanliness of their operating environment—long-term accumulation of dust (including PM2.5 / PM10, conductive dust, salt spray crystals, etc.) can lead to decreased insulation performance (such as shortened creepage distance and increased dielectric loss), reduced heat dissipation efficiency (clogging ventilation holes), increased contact resistance (causing localized overheating), and even induce serious faults such as flashover and short circuits, severely threatening the safety and stability of the power grid. Traditional manual cleaning methods are inefficient, and due to the numerous gaps and pores in the equipment, cleaning is difficult. If dust is removed by blowing air, dust will be blown throughout the machine room, creating secondary dust accumulation.
[0003] Therefore, there is an urgent need for a high-efficiency dust removal device to achieve the cleaning and maintenance of the internal space of substations. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a dust removal device for wind power substations, comprising a base plate and a collection box. The upper surface of the base plate is provided with the collection box and a support base. An impeller is rotatably mounted inside the collection box. A second motor is fixedly mounted on the upper surface of the collection box, and the motor shaft of the second motor passes through the collection box and is fixedly connected to the impeller. A connecting rod is rotatably mounted on the end of the support base away from the base plate, and a cleaning head is fixedly connected to the end of the connecting rod away from the support base. The cleaning head is provided with a cleaning brush and a suction port.
