Description

Technical Field

[0001] This utility model relates to the field of insulator cleaning technology, and in particular to an insulator cleaning device. Background Technology

[0002] Insulators are indispensable insulating components in power systems, widely used in overhead transmission lines, substations, and other locations, serving to support and insulate conductors. However, insulators are exposed to the outdoor environment for extended periods, accumulating large amounts of dust, dirt, salt, and other contaminants on their surfaces. These contaminants reduce the insulation performance of insulators, increase leakage current, and can even trigger flashover accidents, leading to equipment tripping, burnout, or even power outages, severely impacting the safe operation and reliability of the power system. Traditional insulator cleaning methods primarily rely on manual labor, such as manual disassembly and cleaning, and cleaning at heights. These methods are not only inefficient, labor-intensive, and costly, but also pose significant safety hazards, easily leading to accidents such as falls from heights. Furthermore, manual cleaning often fails to thoroughly remove dirt from the insulator surface, especially in hard-to-reach areas, leaving blind spots and affecting the cleaning effect. With the continuous development of the power industry and increasing requirements for equipment maintenance, developing a device that can efficiently, safely, and thoroughly clean insulators is particularly important.

[0003] Chinese patent document 201610164560.X discloses an insulator cleaning device. It includes a handheld drive motor and a drive rod connected to the drive motor. A connecting bearing seat is provided between the drive motor and the drive rod, and the connecting bearing seat has a vent hole. The drive rod is a hollow tubular structure, and a high-pressure spray hole is provided at the top of the end of the drive rod away from the connecting bearing seat. A cleaning tape is fitted onto the side wall of the end of the drive rod away from the bearing seat.

[0004] However, the above-mentioned solutions have at least the following technical problems during implementation: traditional insulator cleaning relies on manual labor, which is inefficient, labor-intensive, and makes it difficult to perform high-altitude operations, posing significant safety hazards. Therefore, there is an urgent need to propose an insulator cleaning device. Summary of the Invention

At least two cleaning brushes are mounted below the climbing assembly via a rotary bearing, and a cleaning brush motor for driving the cleaning brushes to rotate is mounted below the cleaning brushes.

[0007] In some embodiments of this disclosure, there are two grippers connected by a retractable structure.

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0019] This example discloses an insulator cleaning device; see [link to documentation]. Figs. 1-2 The system includes a climbing assembly 1 that can be attached to an insulator. The climbing assembly 1 includes grippers 2 for holding the insulator. The grippers 2 include a left gripper 4 and a right gripper 5 connected by a hinged structure 6. The left gripper 4 is fitted with a left nut 8 via a left washer 7, and the right gripper 5 is fitted with a right nut 10 via a right washer 9. The center of the left nut 8 and the right nut 10 is connected to a threaded screw 11. A motor 12 is installed at the end of the screw 11 to drive the screw 11 to rotate, thereby moving the left nut 8 and the right nut 10 on the screw 11 to achieve the tightening and loosening of the grippers 2. At least two cleaning brushes 12 are installed below the climbing assembly 1 via a rotary bearing. A cleaning brush motor 13 is installed below the cleaning brushes 12 to drive the cleaning brushes 12 to rotate.

[0020] There are two grippers 2, which are connected by a retractable structure 3.

[0021] The gripper 2 has an anti-slip structure 14 on the inner side of the insulator.

[0022] The telescopic structure 3 includes multiple hydraulic cylinders mounted between the grippers.

[0023] It also includes a water spray assembly, which includes a water tank 15, a water pipe 16 connected to the outlet of the water tank 15, a cleaning brush installed through the water pipe, and a nozzle 17 installed at the outlet of the water pipe 16.

[0024] It also includes a ash collection box 18, which has a semi-circular structure and is installed below the cleaning brush 12.

[0025] During operation, the insulator cleaning device first attaches itself to the insulator using the grippers 2 of the climbing assembly 1. A motor drives the screw to rotate, causing the left / right nuts to move along the screw and tighten the grippers. A hydraulic cylinder extends and retracts to adjust the clamping distance. During the step-by-step climbing, alternating clamping occurs: the upper gripper is fixed, the lower gripper is released and moves upward, then the lower gripper is fixed again, and the upper gripper is released and moves upward, thus achieving a step-by-step climbing process. During the cleaning phase, the cleaning brush motor starts, driving the brush body to rotate at high speed to scrape away dirt, while the nozzle sprays water mist to wet the surface. Motor 12 drives the screw 11 to rotate, causing the left nut 8 and right nut 10 to move on the screw 11, thereby tightening and loosening the grippers 2. Once the device is stably clamped onto the insulator, the cleaning brush motor 13 drives the cleaning brush 12 to rotate, cleaning the insulator surface. Simultaneously, the water spray assembly begins operation. Water from the water tank 15 is transported to the vicinity of the cleaning brush 12 via the water pipe 16. The nozzle 17 installed at the outlet of the water pipe 16 sprays water out, assisting the cleaning brush 12 in rinsing and improving the cleaning effect. During the cleaning process, the dust collection box 18 is installed below the cleaning brush 12. Its semi-circular structure effectively collects dust and dirt that falls during the cleaning process, preventing secondary pollution and maintaining a clean working environment. Example 2

[0026] The principle of this example is the same as that of Example 1, but the specific differences are as follows:

[0027] The gripper 2 consists of a single jaw. A lifting structure is installed below the gripper. This lifting structure includes a rack 18, which meshes with a gear 19. A motor 20 is mounted on the gear 19 to achieve the lifting and lowering of the gripper 2. During operation, the motor 20 is started, causing the gear 19 to rotate, which in turn drives the rack 18 to move up and down, thus lifting and lowering the gripper 2. (See also...) Fig. 2 . Fig. 2 The height shown is for illustrative purposes only. In specific working conditions, the telescopic height and design height of the insulator cleaning device pole are determined by combining the fixed height at the bottom.

[0028] Although some preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this application and their equivalents, this utility model also intends to include these modifications and variations.
