Description

Technical Field

[0001] This utility model relates to the technical field of foreign object removal devices for power transmission line conductors, and in particular to a foreign object removal device for power transmission line conductors based on unmanned aerial vehicles (UAVs). Background Technology

[0002] With the continuous development of power transmission networks, the coverage of transmission lines is becoming increasingly extensive. However, transmission lines are exposed to the outdoor environment for extended periods and are easily entangled and attached to foreign objects such as kites, plastic films, and bird nesting materials. These foreign objects not only increase the weight and wind resistance of the transmission lines but may also cause serious safety hazards such as short circuits and leakage, threatening the stable operation of the power system. Drones are typically used to remove these objects.

[0003] A search revealed Chinese Patent Publication No. CN218513974U, which discloses a device for removing foreign objects from power transmission line conductors based on a drone. The device includes a drone body and a cleaning mechanism. This allows maintenance personnel to inspect power transmission lines using the drone, simultaneously cleaning debris from the lines without damaging them. This significantly improves the device's practicality.

[0004] Considering that power transmission lines are usually installed outdoors, and outdoor power transmission lines are often affected by wind and sway, the cleaning mechanism in this case uses a drone to directly position the power transmission line in the center of the cleaning mechanism, so that two electric sliders 7 move in opposite directions, allowing the scraper 10 to contact the power line. After the scraper 10 contacts the power line, the drone body 1 can be controlled to move again to clean the debris on the power line. In actual operation, the irregular swaying of the power line makes it difficult for the drone to control its instantaneous position, making positioning extremely difficult. Even if the positioning is successful, the power line may shift again due to wind force during the short period of time when the electric slider drives the scraper, causing the scraper to fail to make accurate contact with the power line, making it difficult to start the cleaning process smoothly. Therefore, a drone-based device for removing foreign objects from power line conductors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for removing foreign objects from power transmission line conductors based on drones. It aims to solve the problem that outdoor power transmission lines are affected by wind and sway irregularly, making it difficult for drones to accurately control their instantaneous position and making positioning extremely difficult. Even if positioning is achieved, the power transmission line may still shift again due to wind force during the movement of the scraper driven by the electric slider, causing the scraper to fail to make accurate contact with the power transmission line and making it difficult to start the cleaning process smoothly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for removing foreign objects from power transmission line conductors based on a drone, comprising a drone, a connector fixedly connected to the bottom of the outer surface of the drone, an inclined plate fixedly connected to the bottom of the connector, a hinge rod hinged to the inner surface of the inclined plate, a traction rod hinged and slidably connected to the top of the outer surface of the hinge rod, an elastic connection between the top of the outer surface of the traction rod and the outer surface of the connector via a spring, a traction ring fixedly connected to the bottom of the outer surface of the traction rod, a limit block fixedly connected to the bottom of the outer surface of the hinge rod, and a cleaning component provided on the inner surface of the connector;

[0007] The cleaning assembly includes an electric slide rail, the outer surface of which is fixedly connected to the top of the inner surface of the connector. An electric slider is slidably connected to the outer surface of the electric slide rail. An L-plate is fixedly connected to the bottom of the outer surface of the electric slider. A fixing plate is fixedly connected to the bottom of the outer surface of the L-plate. A brush is fixedly connected to the inner surface of the fixing plate.

[0008] As a further description of the above technical solution:

[0009] The outer surface of the L-plate is slidably connected to the inner surface of the connector, and the fixing plate is slidably connected to the inner surface of the connector.

[0010] As a further description of the above technical solution:

[0011] A guide post is fixedly connected to the bottom of the outer surface of the connector, and the outer surface of the guide post penetrates and is slidably connected to the inner surface of the traction rod.

[0013] One end of the spring is fixedly connected to the top of the inner surface of the connector, and the other end of the spring is fixedly connected to the top of the outer surface of the traction rod.

[0014] As a further description of the above technical solution:

[0015] Both the fixing plate and the brush are designed to be semi-circular.

[0016] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The electric slide rail is T-shaped.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the linkage design of the hinge rod and the limiting block, when the power transmission line squeezes the traction ring and triggers the traction rod to move, it drives the hinge rod to rotate, causing the limiting block to move inward to lift the bottom of the power transmission line, thus fixing the position of the power transmission line in advance. This ensures that the subsequent brush makes full and accurate contact with the surface of the power transmission line, avoiding incomplete cleaning due to the offset of the power transmission line, and significantly improving the accuracy and effect of cleaning.

[0024] 2. In this utility model, two sets of symmetrically distributed inclined plates form a stable V-shaped guide structure, which can effectively guide the power transmission line to the center position of the connector, thereby reducing the requirements for the initial position of the power transmission line. Even if the power transmission line is not directly under the drone, it can smoothly enter the cleaning work area under the guidance of the inclined plates, which enhances the applicability of the device under different installation environments and power transmission line layouts, and improves the working reliability and application range of the foreign object removal device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a device for removing foreign objects from power transmission line conductors based on a drone. The device includes a drone 1, which serves as the carrier of the entire device. The drone 1 can flexibly fly to the location of the power transmission line for remote-controlled cleaning. A connector 2 is fixedly connected to the bottom of the drone 1's outer surface. The connector 2 connects the drone 1 to other components below, providing a stable support and ensuring the entire device is stably mounted on the drone 1. A ramp 3 is fixedly connected to the bottom of the connector 2. The ramp 3 is designed to guide the power transmission line more smoothly into the center of the connector 2 when the drone 1 descends and approaches the power transmission line, facilitating subsequent cleaning operations. A hinge rod 9 is hinged to the inner surface of the ramp 3, allowing the hinge rod 9 to rotate at a designated position within the ramp 3. A traction rod 5 is hinged and slidably connected to the top of the outer surface of the hinge rod 9. The traction rod 5 can drive the hinge rod 9 to rotate when it moves. The top of the outer surface of the traction rod 5 is elastically connected to the outer surface of the connector 2 through the spring 7. The elastic connection of the spring 7 provides the traction rod 5 with the power to reset. When the pressure of the power line on the traction rod 5 disappears, the spring 7 can drive the traction rod 5 to return to the initial position, so that the entire device can carry out the next cleaning work. The bottom of the outer surface of the traction rod 5 is fixedly connected to the traction ring 8, which is used to contact the power line. When the drone 1 descends, the power line squeezes the traction ring 8, thereby triggering the movement of the traction rod 5, which in turn drives a series of subsequent components to move. The bottom of the outer surface of the hinge rod 9 is fixedly connected to the limit block 10. The limit block 10 moves inward under the drive of the hinge rod 9, which can lift and limit the bottom of the power line. Before the brush 405 clamps and cleans the power line, it stabilizes the position of the power line, improving the accuracy and effect of cleaning.

[0032] Reference Figures 1-3The inner surface of the connector 2 is provided with a cleaning component 4. The cleaning component 4 is the core component for cleaning foreign objects from the surface of the power transmission line. Through its operation, it can effectively remove foreign objects adhering to the surface of the power transmission line. The cleaning component 4 includes an electric slide rail 402. The outer surface of the electric slide rail 402 is fixedly connected to the top of the inner surface of the connector 2. The electric slide rail 402 is fixed to the connector 2, providing a sliding track for the electric slider 401, allowing the electric slider 401 to move along a predetermined path, thereby achieving precise control of the cleaning component's position. The electric slider 401 is slidably connected to the outer surface of the electric slide rail 402. The electric slider 401 slides on the electric slide rail 402, achieving precise displacement through electric control, thereby driving the connected cleaning component closer to or away from the power transmission line to complete the clamping and cleaning operation. An L-plate 403 is fixedly connected to the bottom of the outer surface of the L-plate 403. The L-plate 403 connects the electric slider 401 and the fixed plate 404, transmitting the movement of the electric slider 401 to the fixed plate 404, allowing the fixed plate 404 to move along with the electric slider 401, thus clamping and releasing the transmission line. The fixed plate 404 is fixedly connected to the bottom of the outer surface of the L-plate 403. The fixed plate 404 is used to install the brush 405, and clamps the transmission line under the action of the electric slider 401, allowing the brush 405 to fully contact the surface of the transmission line, thereby achieving the purpose of cleaning foreign objects. The brush 405 is fixedly connected to the inner surface of the fixed plate 404. The brush 405 directly contacts the surface of the transmission line. Through its soft and dense bristles, it can effectively remove dust, debris and other foreign objects attached to the surface of the transmission line, ensuring the normal operation of the transmission line.

[0033] Reference Figures 1-3 The outer surface of L-plate 403 is slidably connected to the inner surface of connector 2, and the fixing plate 404 is slidably connected to the inner surface of connector 2. The slidable connection between L-plate 403 and fixing plate 404 and connector 2 provides guidance and support for their translation, ensuring smooth and accurate movement during the clamping and releasing of the power transmission line, and avoiding deviation that affects the cleaning effect. A guide post 6 is fixedly connected to the bottom of the outer surface of connector 2. The outer surface of guide post 6 penetrates and is slidably connected to the inner surface of traction rod 5. Guide post 6 provides guidance for the movement of traction rod 5, so that when traction rod 5 is squeezed by power transmission line or subjected to the elastic force of spring 7, it can only move in a straight line along the direction of guide post 6, ensuring the stability and accuracy of movement.

[0034] Reference Figures 1-3One end of the spring 7 is fixedly connected to the top of the inner surface of the connector 2, and the other end of the spring 7 is fixedly connected to the top of the outer surface of the traction rod 5. This connection method allows the spring 7 to be compressed and deformed when the traction rod 5 is subjected to external force, storing elastic potential energy. When the external force disappears, the spring 7 releases the elastic potential energy, driving the traction rod 5 to reset, ensuring that the device can be reused. The fixing plate 404 and the brush 405 are both designed as semicircles. The semicircular design can better fit the circular surface of the power transmission line, making the contact area between the brush 405 and the surface of the power transmission line larger, cleaning more comprehensively and thoroughly, and improving cleaning efficiency and effect.

[0035] Reference Figures 1-3 The hinge rods 9 are L-shaped and there are two sets, symmetrically distributed on the left and right sides of the connector 2. The L-shape design is to enable the bottom limiting block 10 to lift the transmission line in time when the traction rod 5 rises. The two sets of symmetrically distributed L-shaped hinge rods 9 can limit and lift the transmission line from both sides, ensuring the stability and balance of the limit and preventing the transmission line from deviating during the cleaning process. There are two sets of inclined plates 3, symmetrically distributed on the left and right sides of the connector 2. The V-shaped guide structure formed by the two sets of symmetrical inclined plates 3 is more stable and can more effectively guide the transmission line into the center position of the connector 2, improving the applicability and reliability of the device. The electric slide rail 402 is T-shaped. The T-shaped electric slide rail 402 can provide better support and stability, and also facilitates the sliding of the electric slider 401 on the track, ensuring the smoothness and accuracy of the cleaning component 4.

[0036] Working principle: When cleaning the power transmission line, the drone 1 first flies up directly above the power transmission line, and then slowly descends. Guided by the inverted V-shape formed by the two sets of inclined plates 3, the power transmission line moves to the center of the connector 2. Then, the power transmission line contacts the bottom of the traction ring 8. Due to the descent of the drone 1, the traction ring 8 is squeezed upward by the power transmission line. When the traction ring 8 moves upward, it simultaneously drives the traction rod 5 to move as well. The traction rod 5 simultaneously drives the two sets of hinge rods 9 to flip along the inner surface of the inclined plate 3, causing the limiting block 10 fixed at the bottom of the hinge rod 9 to move inward, lifting the bottom of the power transmission line. Thus, before the brush 405 clamps the power transmission line, it first provides a simple limit to the power transmission line, allowing the brush 405 to... The system can more accurately clamp the power transmission line. Then, the electric slider 401 is activated, causing the electric slider 401 to move the L-plate 403 inward along the electric slide rail 402. The fixing plates 404 fixed at the bottom of the two sets of L-plates 403 clamp the power transmission line, and the brushes 405 fixed on the fixing plates 404 come into contact with the surface of the power transmission line. Then, the drone 1 is operated to move horizontally, so that the brushes 405 clean the surface of the power transmission line during the movement of the drone 1. When the cleaning is completed, the two sets of electric sliders 401 move the fixing plates 404 outward to release the clamping effect on the power transmission line. Then, the drone 1 moves upward, so that the traction rod 5 loses the squeezing effect of the power transmission line, and the spring force of the spring 7 drives the hinge rod 9 to reset.
