Description
Technical Field
The utility model relates to a high-voltage live working field especially relates to an air-blowing scrubbing device for insulator.
Background
The insulator is an object which can bear certain stress and can bear certain voltage and is arranged between conductors at different potentials or between grounding components, the environment is mostly outdoor, so that substances often exist to cover the surface of the insulator, particularly in winter in the north, when snowfall and low-temperature weather occur, the surface of the insulator is often covered by ice and snow, even conical icicles are distributed along the axis direction of the insulator, and due to the conductivity of water, the insulating strength of the insulator can be greatly reduced, so that the challenge is brought to the high-reliability operation and maintenance of a power grid. The insulator cleaning mode is divided into two modes, namely live cleaning and power failure cleaning. The hot-line cleaning operation has high difficulty and great potential safety hazard, and the power failure cleaning can bring great influence on industrial production and people life. The method for carrying the live working robot to carry out live cleaning by the mobile platform is a feasible method, but because the space, the load and the like of the mobile platform are limited, no cleaning equipment which can be really applied to the mobile platform and has simple structure and high feasibility exists at present.
Similar published patents exist:

This mode of operation is not suitable for machine operation and has a high risk factor due to the large potential for equipment to come into contact with the insulator. Chinese patent with publication number CN 206613754U and publication date 2017, 11 and 7, designs an insulator deicing device, uses a circular arc-shaped clamping plate as a main structure, comprises a fixed clamping plate and a movable clamping plate, when in use, the movable clamping plate is moved outwards to form an opening, then the device is moved to an insulator, and the movable clamping plate is loosened, so that icicles on the surface of the insulator are clamped and broken. The mode has higher cleaning efficiency, but the danger coefficient of the process that the equipment is close to the insulator and the process that the icicle is pinched off is higher, and the mode is not suitable for the operation of a mobile platform.
Therefore, the prior art mainly has three disadvantages, 1, electric drive is used, and the stability is poor, for example, in the chinese patent with publication No. CN 107093865A, a motor is used to drive a tool bit to remove ice, streaming is easily caused during live working, and the safety coefficient is poor; 2. the equipment has large volume or weight and cannot be applied to a mobile platform, for example, although Chinese patents with publication numbers of CN106655053 and publication dates of 2017, 5 and 10 are high in efficiency and strong in anti-interference capability, the equipment is not suitable for the mobile platform due to the large volume; 3. the positioning device can not be used for an automatic system, for example, the device proposed by Chinese patents with publication numbers of CN206613754 and publication dates of 2017, 11, month and 7 can only be used for manual operation, if the positioning device is used for a mechanical arm, the requirement on positioning accuracy is extremely high, and the current positioning technology cannot meet the use requirement.
