Elastic sweeping mechanism of insulator sweeping and scrubbing robot

Abstract

An elastic sweeping mechanism of an insulator sweeping and scrubbing robot comprises a circular-ring-shaped shell. A plurality of inverted-U-shaped fixing frames are evenly arranged on the shell around the circle center, the lower ends of a plurality of U-shaped sweeping mechanism supports are hinged to the shell, and the upper end of each sweeping mechanism support is hinged to the upper portion of the corresponding fixing frame; driving rolls are installed on the side portions of the sweeping mechanism supports, power motors are installed at the bottoms of the sweeping mechanism supports, and the power motors are connected with the driving rolls and can drive the driving rolls to rotate; limiting rings are installed at the upper end and the lower end of each driving roll correspondingly, a scrubbing brush is installed between each two limiting rings, a transmission gear is located above the shell, and the transmission gear is engaged with transmission teeth; a walking motor is installed on a sliding block, a driving gear is installed on an output shaft of the walking motor, the driving gear is engaged with a gear ring, and a camera is installed on the sliding block; and the scrubbing rolling brush can be driven to rotate through the power motor, so that the multiple sweeping mechanism supports are driven to swing synchronously, the contact area and the pressure between the scrubbing rolling brush and the surface of an insulator can be controlled, and a better sweeping and scrubbing effect is achieved.

Description

technical field [0001] The invention relates to an insulator cleaning device, in particular to an elastic cleaning mechanism of an insulator cleaning and decontamination robot. Background technique [0002] Insulators are insulating components used to connect wires and iron towers on overhead high-voltage transmission lines. Since the insulator strings are exposed to the atmosphere for a long time, dust and dirt will accumulate on the surface of the insulator bottle strings, which will easily cause short circuits and reduce the insulation of the insulators on the lines. Performance, the cleaning of the insulator surface, currently adopts the method of manual cleaning, which is dangerous, inefficient and difficult to operate. With the need for the promotion of humanized operations and the development of intelligent robots, more and more intelligent cleaning robots are currently used in power line inspections or equipment inspections. The existing intelligent cleaning robot c...

Problems solved by technology

The existing intelligent cleaning robot can be fixed on the insulator string to clean the surface of the insulator through the cleaning roller brush, but the existing insulator cleaning robot can only clean the dust attached to the surface of the insulator, and it cannot be effectively removed when the surface of the insulator is covered with snow and ice. , It is easy to cause short circuit in winter rainy and snowy weather

The cleaning brush and the driving roller of the existing insulator cleaning and decontamination robot are of an integrated structure. After the cleaning brush is worn out, the entire driving roller needs to be removed for replacement, and the maintenance cost is high. Some people have tried to design a ring-shaped cleaning brush cover It is connected to the driving roller, but when the insulator cleaning and decontamination robot moves along the insulator, the uneven surface of the insulator will cause the ring-shaped cleaning brush to fall off the driving roller

In addition, the existing intelligent cleaning robots are difficult to withstand the harsh outdoor conditions for a long time, and the working hours after charging are limited, and they cannot be exposed to the outdoor environment for a long time. They are all detachable structures. They are installed on the insulators to clean the insulators. After the cleaning is completed, the staff removes the robot and moves to the next set of insulators for cleaning. It is impossible to install on each set of insulators without disassembly. intelligent cleaning robot

It usually takes several hours for an insulator cleaning robot to complete a thorough cleaning of a group of insulators. In order to improve operation efficiency and save labor costs, the staff will not stay on duty after installing cleaning robots on all insulators on a transmission tower, but It is to continue to install the cleaning robot on other transmission towers, and then return to disassemble the cleaning robot after installing several transmission towers. The post-theft cleaning robot case caused huge economic losses to the power company
