Technical Field

[0001] This utility model relates to the field of cable maintenance technology, specifically a cleaning device for overhead power transmission ground wires. Background Technology

[0002] Ground wire cleaning devices play a crucial role in cable maintenance. Their primary function is to remove dust, oil, debris, and other contaminants from the cable surface, maintaining its cleanliness. This effectively prevents insulation corrosion or aging due to contamination, avoiding conductivity problems or equipment malfunctions caused by dirt accumulation. Furthermore, it improves the accuracy of cable inspections by removing surface impurities, ensuring the proper functioning of equipment such as infrared thermometers and discharge detectors. Simultaneously, cleaning the conductive pathways reduces the risk of leakage accidents, thereby ensuring the safety of maintenance personnel and extending the cable's lifespan. These functions are not only applicable to routine cleaning but also create favorable operating conditions for subsequent maintenance.

[0003] The significance of ground wire cleaning devices lies primarily in enhancing the stability and security of power grid operation and protecting critical cable assets. Regular cleaning reduces equipment failure rates, minimizes power outages caused by external pollution, provides crucial assurance for the reliability of the power system, and optimizes the quality of power supply services. Furthermore, cleaning devices can reduce cable maintenance and replacement costs, extend cable lifespan, and offer long-term economic benefits. In complex working environments, such as coastal industrial areas or dusty regions, cleaning devices are particularly important, helping cables better adapt to environmental changes. Modern ground wire cleaning devices are also developing towards automation and intelligence, achieving unmanned operation through linkage with detection equipment, which helps improve maintenance efficiency and reduce operational risks. Therefore, this device plays an irreplaceable role in cable maintenance.

[0004] Existing technical solutions have the technical problem of not being able to automate cable cleaning. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning device for overhead power transmission ground wires, which solves the technical problem that existing technical solutions cannot automatically clean cables.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for overhead power transmission ground wires, comprising a main frame, a guide sleeve on the main frame, a guide rod slidably installed inside the guide sleeve, a telescopic block fixedly installed at one end of the guide rod, an upper connecting rod, a left connecting rod, and a right connecting rod rotatably installed on the main frame, an upper roller brush rotatably installed at the other end of the upper connecting rod, a left roller brush rotatably installed at the other end of the left connecting rod, a right roller brush rotatably installed at one end of the right connecting rod, and an upper small connecting rod, a left small connecting rod, and a right small connecting rod rotatably installed on the telescopic block, the upper small connecting rod, the left small connecting rod, and the right small connecting rod being rotatably connected to the middle sections of the upper connecting rod, the left connecting rod, and the right connecting rod, respectively.

[0007] Preferably, a cylinder is fixedly installed on the main frame, and the telescopic end of the cylinder is fixedly connected to the telescopic block.

[0008] Preferably, an upper drive motor is fixedly installed at the other end of the upper connecting rod, and the drive end of the upper drive motor is fixedly connected to one end of the upper roller brush.

[0010] Beneficial effects

[0011] This invention provides a cleaning device for overhead power transmission ground wires. The device uses an upper drive motor, a left drive motor, and a right drive motor to control the upper, left, and right roller brushes respectively, achieving fully automated cleaning of the ground wire. Compared to manual cleaning or the limitations of traditional devices, the automated design significantly improves cleaning efficiency while reducing errors caused by manual operation or environmental factors. This ensures thorough cleaning of the ground wire surface, improves work quality, and effectively solves the technical bottleneck of existing technologies that cannot achieve automated cleaning. The device cleverly utilizes the flexible connection between the upper, left, and right connecting rods and the small connecting rod, allowing the three sets of roller brushes to precisely conform to the ground wire surface according to the adjustment of the guide rod. The vertically intersecting design of the rotation axes of the upper and lower roller brushes, combined with the coverage of the left and right roller brushes, enables comprehensive cleaning of all angles of the ground wire, achieving 360° cleaning without dead angles. Furthermore, through the sliding design of the guide rod and telescopic block, the device can adapt to overhead ground wires of different diameters and shapes, accommodating diverse working conditions. The roller brushes of the device employ a highly efficient and gentle cleaning method, without damaging the outer sheath, metal parts, or insulation layer of the ground wire. At the same time, by removing dust, dirt and debris, corrosion or short circuit problems caused by pollutants are prevented, thereby effectively reducing the aging rate and failure rate of the ground wire and extending the service life of the power transmission ground wire.

[0017] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Detailed description follows.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a cleaning device for overhead power transmission lines, including a main frame 15, a guide sleeve on the main frame 15, a guide rod 7 slidably installed inside the guide sleeve, a telescopic block 16 fixedly installed at one end of the guide rod 7, an upper connecting rod 1, a left connecting rod 3 and a right connecting rod 5 rotatably installed on the main frame 15, an upper roller brush 9 rotatably installed at the other end of the upper connecting rod 1, a left roller brush 10 rotatably installed at the other end of the left connecting rod 3, a right roller brush 11 rotatably installed at one end of the right connecting rod 5, and an upper small connecting rod 2, a left small connecting rod 4 and a right small connecting rod 6 rotatably installed on the telescopic block 16, the upper small connecting rod 2, the left small connecting rod 4 and the right small connecting rod 6 being rotatably connected to the middle sections of the upper connecting rod 1, the left connecting rod 3 and the right connecting rod 5 respectively.

[0019] In this embodiment, a cylinder 8 is fixedly installed on the main frame 15, and the telescopic end of the cylinder 8 is fixedly connected to the telescopic block 16.

[0020] In this embodiment, the other end of the upper connecting rod 1 is fixedly equipped with an upper drive motor 12, the drive end of the upper drive motor 12 is fixedly connected to one end of the upper roller brush 9, and the rotation axis of the upper roller brush 9 is perpendicular to the rotation axis of the left roller brush 10 and the right roller brush 11.

[0021] In this embodiment, the left connecting rod 3 is further configured to have a left drive motor 13 fixedly installed at the other end, the right connecting rod 5 is fixedly installed at one end, the left roller brush 10 is fixedly connected to the drive end of the left drive motor 13, and the right roller brush 11 is fixedly connected to the drive end of the right drive motor 14.

[0022] Its detailed connection methods are well-known technologies in this field; such as Figure 1-4 As shown, fix the cleaning device at a suitable position on the overhead power line (cable starting point), ensuring the main frame 15 is securely installed and properly aligned with the cable. Check the internal connecting components of the device, including the guide sleeve, guide push rod, connecting rod, etc., to ensure they are operating normally, and check the smooth operation of the roller brush motor and cylinder 8. Turn on the power to the device, and adjust the initial position of cylinder 8 according to the specific diameter of the cable and the operating environment, so that the guide push rod and telescopic block 16 maintain an appropriate working distance from the cable.

[0023] The cylinder 8 is activated, causing it to drive the guide rod 7 forward. The linear motion of the guide rod 7 drives the upper connecting rod 2, left connecting rod 4, and right connecting rod 6, further propelling the upper connecting rod 1, left connecting rod 3, and right connecting rod 5 to rotate and swing. With the cooperation of the connecting rods and the overall linkage mechanism, the roller brushes (upper roller brush 9, left roller brush 10, and right roller brush 11) gradually approach the cable, achieving a self-adaptive cleaning preparation state that conforms to the cable surface. Once the roller brush mechanism is close to the cable, the motors of the upper roller brush 9, left roller brush 10, and right roller brush 11 drive the roller brushes to rotate synchronously. The upper roller brush 9 cleans the top of the cable, the left roller brush 10 cleans the left side of the cable, and the right roller brush 11 cleans the right side of the cable, achieving comprehensive cleaning coverage of the cable and removing surface dust, oil, and debris.

[0024] After cleaning the current section of cable, cylinder 8 reverses the direction of the guide push rod, causing it to swing along the small connecting rod and the connecting rod. The roller brush system then moves away from the cable being cleaned and detaches from the cable surface. The entire mechanism moves to the starting position of the next cable section, ready to begin subsequent work. This process can be repeated depending on the length of the cable and the cleaning area.

[0025] For cleaning cables of different diameters or under different stress structures, the stroke of cylinder 8 and the range of motion of the guide push rod can be adjusted to accommodate various cable diameters. After prolonged use, the wear of the roller brush should be checked regularly, and any adhering substances on the roller brush surface should be cleaned promptly to prevent a decrease in cleaning efficiency. Simultaneously, the moving joints of the linkage mechanism should be lubricated to ensure smooth movement.

[0026] Through the above steps, the cleaning device can automatically adhere to the cable to complete efficient cleaning, while also possessing the flexibility to quickly detach, ensuring the continuity and safety of the operation. This method of use greatly reduces the burden of manual maintenance and effectively improves the efficiency and reliability of cable cleaning work.

[0027] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
