Embodiment Construction

[0023] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0024] like figure 1 As shown, the first embodiment of the cleaning device according to the present invention includes three cleaning parts 9, a connecting part, and an operating part. Each cleaning member 9 includes a support rod, a winding part 20 and a cutting part 30 . The winding part 20 is arranged on the support rod (shown in the figure), the cutting part 30 is arranged on the support rod, and in the radial direction of the support rod, the distance between the outer edge of the cutting part 30 and the axis of the support rod is less than or It is equal to the distance between the outer edge of the wrapping portion 20 and the axis of the support rod. The conne...

Abstract

The invention provides a cleaning device comprising multiple cleaning members, a connecting part and an operation part. Each cleaning member comprises a supporting rod, a winding part and a cutting part. The winding part and the cutting part are arranged on the supporting rod. In a radial direction of the supporting rod, distance between the external edge of the cutting part and the axis of the supporting rod is less than or equal to distance between the external edge of the winding part and the axis of the supporting rod. The multiple cleaning members are connected together by the connecting part. The winding parts of all the cleaning members are rotatably installed on the connecting part. The multiple cleaning members are provided with working positions which wrap a power transmission line along a circumferential part of the power transmission line. The operation part is connected on the connecting part or at least one supporting rod. According to the cleaning device, the power transmission line is not damaged, and the power transmission line is cleaned from multiple directions of the power transmission line simultaneously.

Description

technical field [0001] The invention relates to the technical field of power line cleaning, in particular to a cleaning device. Background technique [0002] At present, due to natural or human factors, light and slender filaments such as plastic color strips, aluminum foils, kite lines, magnetic tapes, etc. are hung and wound on transmission lines. If the filaments hanging on the line are conductive If the power supply is damaged, it may lead to a power accident such as line grounding or short circuit, which not only affects the power supply, but also poses a huge threat to people and electrical equipment due to the huge short-circuit current and high voltage. Only from the accident statistics of Beijing Power Grid in the past ten years, the power grid failure caused by the filament hanging on the transmission line accounts for about 20% of the total power grid failure. Therefore, eliminating the filaments entangled on the transmission line as soon as possible has become o...
