Cleaning device for insulators of electric lines

Abstract

The invention relates to a cleaning device for insulators of electric lines. The cleaning device is characterized by comprising a cleaning module, a lifting module, a walking module, a water pipe box, a water tank and a water pump, wherein the cleaning module is fixed to the walking module by virtue of the lifting module, the water pipe box, the water tank and the water pump are all fixed to the walking module, and the water pipe box is connected with the water tank by virtue of the water pump; the cleaning module comprises a cleaning arm, a nozzle, a sliding block, a screw-nut mechanism, a guide rail, guide rail brackets and a workbench; a workbench water outlet is formed in the workbench, the guide rail brackets are arranged on the outer side of the workbench water outlet, the guide rail is fixed to the guide rail brackets by virtue of screws, a connecting frame is horizontally connected between the two adjacent guide rail brackets, the screw-nut mechanism is fixed to the outer side of the middle of the connecting frame along a vertical direction, and the screw-nut mechanism comprises a screw connecting plate, a screw nut, a screw, bearing seats, a coupling and a stepping motor; the stepping motor is connected with screw by virtue of the coupling, and the bearing seats sleeve both ends of the screw.

Description

technical field [0001] The invention relates to the technical field of power line maintenance, in particular to a power line insulator cleaning device. Background technique [0002] Insulators are essential in power lines. They play a role in preventing current from flowing between conductors with different potentials or returning to the ground. They can also support the conductors and withstand the corresponding mechanical stress. Insulators operating outdoors will be polluted by dust, smoke and industrial emissions, forming a dirty layer on the porcelain surface. The surface flashover of polluted insulators under the action of voltage is also called pollution flashover. In a dry state, insulators are not greatly affected by surface pollution flashover, but in climatic conditions such as fog, dew, snow, drizzle, etc., the pollution layer on the surface of the insulator is damp, and its flashover voltage is greatly reduced, which will lead to pollution flashover accidents. ...

[0003] The Chinese patent with the application number 201510334199.6 discloses an automatic cleaning system for insulators. The system places the removed insulators on a rotating tray device, and transports the insulators to the cleaning mechanism for cleaning through a mechanical arm. The entire project has a high degree of automation, but The process is complicated, the insulator needs to be removed, and it cannot work online

[0004] The Chinese patent No. 201410404083.0 discloses an electric cleaning device for insulators. The electric cleaning head in the device is connected to the cleaning joint above the water tank, and an electric cleaning arm is arranged above the cleaning joint seat. The stepping motor is used to drive the electric cleaning device. The cleaning arm rotates, the disadvantage is that the cleaning work of the device is only completed by the rotation of a single cleaning head, and the work efficiency is not high
