Description

Technical Field

[0001] The invention relates to the technical field of overhead line cleaning, in particular to a device for clearing obstacles of power transmission and transformation lines. Background Art

[0002] In daily use, power transmission and transformation lines are installed at the top of utility poles and are suspended in the air all year round. In order to prevent short circuits and other conditions in power transmission and transformation lines during daily use, it is necessary to clean the outside of the power transmission and transformation lines. The device required in the cleaning process is also called an obstacle clearing robot.

[0003] The existing obstacle clearing robots have the problem that the snow surface is too hard to be cleared when clearing snow. The reason for this problem is that the power transmission and transformation lines are installed on the top of outdoor poles, and most of them are suspended in the air. Therefore, obstacles often appear on the outside of the power transmission and transformation lines, and obstacles often cause the power transmission and transformation lines to fail to operate normally. Therefore, it is necessary to clean the outside of the power transmission and transformation lines, especially in the snowy winter season. Large areas of snow will accumulate on the outside of the power transmission and transformation lines. These snows will not only exert a certain gravity pressure on the power transmission and transformation lines, but also cause A short circuit occurs in the power transmission and transformation line, and the location of the power transmission and transformation line is relatively high. A cleaning robot is needed to handle the power transmission and transformation line. The robot will drive the brush in front to rotate, so as to clean the snow outside the power transmission and transformation line. However, some snow accumulation positions are not cleaned in time, resulting in a certain melting of the snow surface under the sun. At night, the melted part of the snow surface will refreeze, which makes the surface of some snow harder. The traditional method of using brush bristles for cleaning cannot clean the frozen snow on the surface. Therefore, we propose a power transmission and transformation line obstacle cleaning device. Summary of the invention

[0004] In order to overcome the technical defect that the existing traditional brush cleaning robot cannot clean the frozen snow on the line surface, the present invention provides a power transmission and transformation line obstacle cleaning device.

[0005] The present invention provides a power transmission and transformation line obstacle cleaning device, comprising a cleaning robot body, a rotating drive and a cleaning disk, wherein the rotating drive is arranged on the cleaning robot body, the cleaning disk is installed to the output end of the rotating drive and rotates with the output shaft, the cleaning disk is a round pancake-shaped structure, a plurality of evenly arranged cleaning brushes are arranged on the circumferential side wall of the cleaning disk, a cross-shaped telescopic mechanism is arranged on the outer end surface of the cleaning disk, an electric telescopic rod is arranged on each leg of the cross-shaped telescopic mechanism, a scraper is fixedly connected to the end of the electric telescopic rod, and the telescopic movement of the electric telescopic rod is controlled by the cleaning robot body.

[0006] Four sets of scrapers are connected to the cross-shaped telescopic mechanism. The scrapers are used to deal with the excessively accumulated snow and ice outside the line. The electric telescopic rod drives the scrapers to move when it is extended and retracted. The cleaning robot adjusts the position of the scrapers according to the height of the snow so that the scrapers can scrape off the frozen ice on the surface of the snow. The scrapers will not damage the power transmission and transformation lines. Therefore, the cross-shaped telescopic mechanism and the scrapers connected thereto can remove the ice on the outside of the snow at different heights. Start the cleaning robot, move it along the line, rotate the drive to drive the cleaning disk to rotate, and the rotation of the cleaning disk drives the scrapers and cleaning brushes to rotate. The scrapers can scrape off the ice on the surface of the snow, and the cleaning brush can sweep the remaining snow on the line.

[0007] Preferably, the electric telescopic rod includes a fixed rod and a pushing rod, the fixed rod is fixed, two sliding rods are fixedly connected to the left and right sides of the fixed rod respectively, the pushing rod is movably installed to the front end of the fixed rod, the axes of the sliding rod, the fixed rod and the pushing rod are parallel, a moving plate is fixed to the front end of the pushing rod, the moving plate is perpendicular to the axis of the pushing rod, and support rods parallel to the pushing rod are extended to the left and right sides of the moving plate, the support rod is connected with a ferrule, the ferrule and the corresponding position of the sliding rod are slidably matched, and the scraper is installed on the moving plate through a connecting seat. When the pushing rod is extended forward and backward, it will drive the moving plate to move forward and backward, and the moving plate will drive the support rods on both sides thereof to move along the sliding rod, and the ferrule on the support rod will cooperate with the sliding rod limiter to make the moving plate and the scraper move along the axis of the pushing rod and the fixed rod.

[0008] Preferably, a protective shell is installed on the outer side of the slide bar. The protective shell can prevent debris from getting stuck between the slide bar and the ferrule.

[0009] Preferably, a mounting ring is arranged on the circumferential side wall of the cleaning disc, and the cleaning brush is connected to the mounting ring, and the cleaning brush is evenly distributed along the circumference of the mounting ring. Such a reasonable structure is arranged, and the installation and replacement of the cleaning brush are convenient.

[0010] Compared with the prior art, the technical solution provided by the present invention has the following technical effects: the device described in the present invention can adjust the position of the scraper according to the height of the snow accumulation, so as to scrape off the ice layer outside the snow accumulation at different heights. When the cleaning robot is started to clean, the rotating driver drives the cleaning disk to rotate, and the cleaning disk drives the scraper to rotate during the rotation. As the scraper rotates, the ice layer on the surface of the snow accumulation is scraped off, and as the cleaning brush rotates, the remaining snow is swept off the outer surface of the power transmission and transformation line. The scraper is arranged in front of the cleaning brush, which is very reasonable. The ice layer outside the snow accumulation can be scraped off before the cleaning brush sweeps the snow, which is convenient for the subsequent cleaning brush to clean the remaining snow on the line. The line cleaning effect of the device described in the present invention is good. BRIEF DESCRIPTION OF THE DRAWINGS
