Embodiment 1

[0044] Such as Figure 1-3 As shown, this embodiment provides a transmission line insulator cleaning robot, including an upper support 1 and a lower support 2 connected to the upper support 1 through an electric push rod 3; the electric push rod 3 is close to the upper support 1 The position is provided with an upper clamping assembly 4 arranged around to clamp the insulator steel cap; the position of the electric push rod 3 close to the lower support 2 is provided with a lower clamping assembly 5 arranged around it to clamp the steel cap of the insulator; Both the upper bracket 1 and the lower bracket 2 are provided with a cleaning mechanism 6 for cleaning insulators.

[0045] The upper bracket 1 is an annular structure with a first notch, and the first notch is provided with an upper sealing member 7 having the same shape as the first notch, and the upper sealing member 7 is connected to the upper bracket 1 One end is provided with an upper seal motor 8 for driving the rota...

Embodiment 2

[0051] Such as Figure 4 As shown, this embodiment provides a transmission line insulator cleaning robot which is an improvement on the basis of Embodiment 1: a blowing module and a spraying module are installed at both ends of the arc track 61, and the blowing module includes The motor fan 64 that is arranged on the two ends of the arc track 61; the spray washing module includes nozzles arranged at the two ends of the arc track 61, a nozzle 65 connected to the nozzle, and the nozzle is connected to the liquid delivery unit. The liquid delivery unit includes a mobile tool trolley and a liquid storage barrel arranged on the mobile tool trolley, and the liquid storage barrel is connected to the spray pipe through a centrifugal pump.

[0052] Cleaning fluid or water can be stored in the liquid storage barrel. The steps of use are to clean with the brush roller 63 first, and then turn on the motor fan 64 to blow away the dust after cleaning to keep the surface of the insulator cle...

Embodiment 3

[0054] This embodiment provides a method for loading a power transmission line insulator cleaning robot described in Embodiment 2, and the decomposition steps are as follows:

[0055] S1: First, the self-locking components 11 on the upper bracket 1 and the lower bracket 2 are unlocked, the rotation motor 113 is reversed, and the extension motor 114 is reversed to drive the self-locking bolt 111 to withdraw along the thread of the self-locking nut 112;

[0056] S2: When the self-locking bolt 111 is fully withdrawn, the upper sealing motor 8 reverses to drive the upper sealing member 7 to rotate, and the lower sealing motor 10 reverses to drive the lower sealing member 9 to rotate, so that the upper bracket 1 and the lower bracket 2 respectively open a gap;

[0057] S3: The staff uses the insulating rod to lift the robot to the bottom of the insulator string to be operated. The gaps of the upper bracket 1 and the lower bracket 2 correspond to the positions of the insulator steel ...

Abstract

The invention provides a power transmission line insulator cleaning robot and method, and belongs to the technical field of insulator cleaning. The power transmission line insulator cleaning robot comprises an upper-layer support and a lower-layer support connected with the upper-layer support through an electric push rod; an upper clamping component which is arranged in a surrounding manner to clamp an insulator steel cap is arranged in the position, close to the upper-layer support, of the electric push rod; a lower clamping component which is arranged in a surrounding manner to clamp the insulator steel cap is arranged in the position, close to the lower-layer support, of the electric push rod; and the upper-layer support and the lower-layer support are provided with sweeping mechanismsused for sweeping the insulators. According to the power transmission line insulator cleaning robot and method, the steel caps of the insulators are clamped by using clamping jaws, so that large clamping force is achieved and crawling is stable; and as the whole frame is of a symmetrical structure, the center of the robot is prevented from deviating; The structure is simple, and the dead weight is low; a worker can easily assemble, disassemble and carry the robot through an insulating rod; alternate operation on different insulator chains is facilitated; the power transmission line insulatorcleaning robot can be used for cleaning with bristles, cleaning with liquid and blow-drying, can clean stubborn stains, and thoroughly cleans dirt on the surface of the insulator.

Description

technical field [0001] The invention relates to the technical field of cleaning insulators of power transmission lines, in particular to a robot and method for cleaning insulators of power transmission lines. Background technique [0002] Due to the long-term outdoor use of transmission line insulators, dust is easy to adhere to the surface, which reduces its insulation capacity. In wet weather, dirty insulators are prone to flashover discharge, that is, pollution flashover, causing power outages, threatening the safety of power supply, and seriously affecting the safe operation of the power system. [0003] Cleaning the dirt accumulated on insulators is one of the main tasks in the maintenance of transmission lines. At present, the cleaning of insulators is carried out by manually climbing the tower and using brushes or rags during power outage maintenance of transmission lines. The working environment of this cleaning method is dangerous and harsh, the cleaning task is h...
