Description

Technical Field

[0001] The invention relates to the technical field of power network operation and maintenance, and in particular to an overhead transmission line insulator cleaning device. Background Art

[0002] Overhead transmission insulators are used in power transmission lines to provide electrical insulation and mechanical support, ensuring that the conductors are isolated from the supporting structure to prevent current leakage and short circuits. Common materials include porcelain, glass, composite materials and silicone rubber. Composite insulators are widely used in high-voltage and ultra-high-voltage lines due to their pollution resistance and impact resistance. With the development of technology, insulators are constantly upgraded to cope with severe weather, environmental pollution and mechanical loads to ensure the safe and stable operation of transmission lines.

[0003] For example, a device for cleaning overhead power transmission lines and insulators disclosed in Chinese patent publication number (CN205429580U) states: "It includes a retractable insulating rod, a brush base plate and brush wires. The length of the retractable insulating rod is adjusted by a retractable switch. The upper and lower edges and the middle position of the brush base plate are respectively provided with an LED bulb, a high-definition camera and a nozzle. The LED bulb is connected to the bulb switch, and the state of the LED bulb is controlled by the bulb switch. The high-definition camera is connected to the display screen, and the disconnection state is controlled by the camera switch. A lithium battery pack is used to power the LED bulb, the high-definition camera and the display screen, and is connected to a USB charging port. When dirt is found, the nozzle is responsible for flushing the dirt. The device can not only visually clean the transmission lines and insulators, but also can be used at night and in dim conditions. The utility model has high cleaning efficiency, a wide range of applicable environments, a simple structure, and flexible use, and has good practical value."

[0004] In summary, the device also has the following technical problems: due to the high height of overhead power transmission, insulators are generally cleaned manually from high altitude. The device is a long pole type as a whole, and the insulator is round as a whole. The insulator needs to be cleaned around it during cleaning. The device needs to constantly adjust the cleaning angle when cleaning around the insulator, which will result in a long cleaning time. In addition, most of the insulators are connected together in a string, and the gaps in the middle of some insulators are small, which will make it impossible to fully clean the insulators. Therefore, it is necessary to propose an overhead transmission line insulator cleaning device to provide a new technical solution to solve the technical problems mentioned in the above patents.

At the same time, the first cleaning ring and the second cleaning ring are arranged in an embracing type, which can achieve full coverage of the insulator. During the process, the cleaning roller is inserted into the gap between the insulators. Through the rotation of the cleaning roller and the spraying of water on the rotating shaft, the insulator can be quickly and comprehensively cleaned.
