Description

Technical Field

[0001] This invention relates to the field of power transmission line cleaning technology, and in particular to a device and method for removing foreign objects from power transmission lines based on unmanned aerial vehicle (UAV) technology. Background Technology

[0002] Currently, foreign objects such as plastic sheeting and garbage bags are easily entangled in high-altitude power transmission lines. If these foreign objects are not cleaned for a long time, they can easily cause line tripping and short circuits. Therefore, it is necessary to regularly inspect power transmission lines and remove foreign objects using drones. A foreign object removal device for power transmission lines that relies on drone technology is used. By setting scissors and grippers under the drone, the foreign objects are clamped by the grippers and then cut by the scissors when removing them.

[0003] In the aforementioned prior art, foreign objects are clamped and cut at high altitudes, but the power transmission lines cannot be restricted. As a result, the power transmission lines at high altitudes are prone to swaying and shaking, making it impossible for the scissors to cut accurately. Furthermore, the clamped foreign objects are also prone to slipping off with the swaying of the lines, affecting the removal efficiency and effectiveness. Summary of the Invention

Detailed Implementation

[0036] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0037] This invention provides a foreign object removal device for power transmission lines based on UAV technology, comprising a control terminal box 1, a support plate 2, multiple insulating mounting blocks 3, and a removal assembly. The removal assembly includes a clamping drive unit, a first clamping cylinder 4, a second clamping cylinder 5, a cutting wheel 6, and a rotating winding rod 7. The removal assembly also includes a clamping adjustment unit, which includes an inclined component 8, an inclined chamber 9, a rotating component 10, a rotating chamber 11, and multiple auxiliary rods 12. The inclined chamber 9 has an annular groove 13. The clamping drive unit includes a central support block 14, two threaded rods 15, two movable mounting blocks 16, and two drive components 17. The removal assembly further includes... The device includes a cutting drive unit, a winding drive unit, and multiple cameras 20. The cutting drive unit includes a screw compressor 21, a cutting telescopic component 22, and a protective plate 23. The winding drive unit includes a winding flipping component 24, a winding telescopic component 25, a winding telescopic frame 26, a winding drive component 27, a winding drive shaft 28, two winding auxiliary mechanisms, and a winding crushing mechanism. The winding auxiliary mechanism includes an auxiliary sliding component 29, an auxiliary support shaft 30, and an auxiliary winding wheel 31. The winding crushing mechanism includes a crushing telescopic component 36, an arc plate 37, and multiple crushing wheels 38. The winding crushing mechanism also includes an inclined plate 39, a magnetic slider 40, and a collection groove 41.

[0038] Please refer to Figures 1 to 4 Multiple insulating mounting blocks 3 and the control terminal box 1 are sequentially arranged above the support plate 2, the clamping drive unit is arranged below the support plate 2, the first clamping cylinder 4 and the second clamping cylinder 5 are symmetrically arranged on the clamping drive unit, the cutting wheel 6 is arranged inside the first clamping cylinder 4, and the rotating winding rod 7 is arranged inside the second clamping cylinder 5. Before the drone takes off, the insulating mounting block 3 is first installed and fixed to the drone. The insulating mounting block 3 serves as insulation to ensure the safety of the drone. The control terminal box 1 is connected to the upper system to send control commands. After the drone discovers strips of cloth or plastic bags wrapped around the power line during inspection, it activates the clamping drive unit, which drives the first clamping cylinder 4 and the second clamping cylinder 5 to move relative to each other, clamping and wrapping the area of ​​the power line with foreign objects. Then, the cutting wheel 6 cuts the strips of cloth or plastic bags. Then, the rotating winding rod 7 is activated to wrap the cut strips of cloth or plastic bags around and pull them into the second clamping cylinder 5, so that they are detached from the power line. When the foreign object is clumps of feces, the first clamping cylinder 4 and the second clamping cylinder 5 wrap around the power line and move laterally. The scraper set at the front end of the clamping cylinder scrapes off the clumps of feces. Finally, the first clamping cylinder 4 and the second clamping cylinder 5 release the clamps, and the drone flies to the next foreign object area for removal.

[0039] Secondly, please refer to Figures 1 to 3The clamping adjustment unit is located below the support plate 2, and the clamping drive unit is located on the clamping adjustment unit. The tilting chamber 9 has an annular groove 13. The tilting component 8 is located below the support plate 2. The tilting chamber 9 is located at the output end of the tilting component 8. The rotating component 10 is located inside the tilting chamber 9. The rotating chamber 11 is located at the output end of the rotating component 10. One end of each of the plurality of auxiliary rods 12 is fixedly connected to the rotating chamber 11, and the other end of each of the plurality of auxiliary rods 12 is slidably connected to the annular groove 13. Both the tilting component 8 and the rotating component 10 are self-locking motors. When the tilting component 8 is activated, it drives the tilting chamber 9 to rotate, causing the clamping drive unit to tilt. At the same time, the rotating component 10 is activated, driving the rotating chamber 11 to rotate and adjust, thereby driving the clamping drive unit to adjust the clamping angle. This allows the first clamping cylinder 4 and the second clamping cylinder 5 to be aligned with the power transmission line. When the rotating chamber 11 rotates, the auxiliary rods 12 slide in the annular groove 13, improving rotational stability.

[0040] Please also see Figure 2 The intermediate support block 14 is disposed inside the rotating chamber 11. A pressing component 18 is disposed inside the intermediate support block 14. A pressing block 19 is disposed at the output end of the pressing component 18. The driving component 17 is disposed outside the rotating chamber 11. One end of the two threaded rods 15 is symmetrically disposed on the intermediate support block 14. The other end of the two threaded rods 15 is disposed at the output end of the corresponding driving component 17. One end of the two movable mounting blocks 16 is adapted to the corresponding threaded rods 15. The other end of the two movable mounting blocks 16 is bolted to the first clamping cylinder 4 and the second clamping cylinder 5, respectively. The intermediate support block 14 supports the threaded rod 15, and the drive component 17 is a self-locking motor. When the drone moves the first clamping cylinder 4 and the second clamping cylinder 5 to the outside of the power transmission line, the drive component 17 is activated to rotate the threaded rod 15, causing the movable mounting block 16 to move. This, in turn, causes the first clamping cylinder 4 and the second clamping cylinder 5 to wrap around the power transmission line. Then, the pressing component 18 inside the intermediate support block 14 is activated. The pressing component 18 drives the pressing block 19 to press and fix the foreign object on the power transmission line, preventing the foreign object from falling off or shifting. Then, the subsequent foreign object cutting operation is performed.

[0041] Additionally, please see Figures 1 to 4The cutting drive unit is located inside the first clamping cylinder 4, the winding drive unit is located inside the second clamping cylinder 5, and multiple cameras 20 are respectively located inside the intermediate support block 14 and the rotating chamber 11. The cutting drive unit cuts the pressed foreign object, and after cutting, the pressing is released. Then, the winding drive unit winds the foreign object and places it inside the second clamping cylinder 5. The cameras 20 can help the operator remotely observe the position of the foreign object for precise clamping and cutting.

[0042] Then, please see Figure 5 The screw compressor 21 is located inside the first clamping cylinder 4. The output end of the screw compressor 21 is provided with the cutting telescopic component 22. The output end of the cutting telescopic component 22 is fixedly connected to the protective plate 23. The cutting wheel 6 is located inside the protective plate 23. The screw press 21 starts, driving the cutting telescopic component 22 to move, thereby positioning the protective plate 23 at one end of the first clamping cylinder 4. Then, the cutting telescopic component 22 starts, causing the protective plate 23 to extend and adhere to the power line. At this time, the first clamping cylinder 4 moves along the power line, and the protective plate 23 is inserted between the foreign object (cloth strip or plastic bag) and the power line, separating the power line from the cutting wheel 6. The cutting wheel 6 starts and, with the operation of the screw press 21, drives the protective plate 23 and the cutting wheel 6 to move, cutting the foreign object so that it is no longer wrapped around the outside of the power line, thus allowing for subsequent wrapping operations. In addition, the cutting telescopic component 22 is a self-locking cylinder with a pressure sensor at its output end to detect pressure changes. When a pressure change is triggered, it indicates that the protective plate 23 has made contact with the power line, and can then move laterally to separate the foreign object from the power line.

[0043] Please see again. Figures 6 to 8The winding and turning component 24 is disposed inside the second clamping cylinder 5. The output end of the winding and turning component 24 is provided with the winding telescopic component 25. The output end of the winding telescopic component 25 is fixedly connected to the winding telescopic frame 26. The winding drive component 27 is disposed on the inner side wall of the winding telescopic frame 26. The output end of the winding drive component 27 is fixedly connected to one end of the winding drive shaft 28. The winding drive shaft 28 is rotatably connected to the winding telescopic frame 26. The other end of the winding drive shaft 28 passes through the winding telescopic frame 26 and is fixedly connected to the rotating winding rod 7. The two winding auxiliary mechanisms are symmetrically disposed on both sides of the winding telescopic frame 26. The winding crushing mechanism is disposed inside the second clamping cylinder 5. The winding and flipping component 24 and the winding drive component 27 are both self-locking motors, and the winding telescopic component 25 is a self-locking cylinder. During winding, the winding telescopic component 25 is activated, driving the winding telescopic frame 26 to move. When the pressure value of the pressure sensor set on the winding telescopic component 25 changes, it indicates contact with a foreign object. At this time, the winding drive component 27 is activated, driving the winding drive shaft 28 to rotate, causing the rotating winding rod 7 to rotate. At the same time, the winding auxiliary mechanism also operates, thereby winding the cut foreign object onto one side of the second clamping cylinder 5. Then, the winding and flipping component 24 is activated, driving the winding telescopic frame 26 to flip into the second clamping cylinder 5, moving the foreign object into the second clamping cylinder 5. Then, the winding crushing mechanism is activated to crush and collect the clamped foreign object, so as to free up the rotating winding rod 7 for subsequent winding and collection of other foreign objects.

[0044] And please see Figures 6 to 8The winding drive shaft 28 and the auxiliary support shaft 30 both have a first groove 32, and the winding telescopic frame 26 and the auxiliary winding wheel 31 both have a second groove 33. An infrared emitter 34 is disposed in the first groove 32, and an infrared receiver 35 is disposed in the second groove 33. The auxiliary sliding component 29 is disposed inside the winding telescopic frame 26, and the auxiliary support shaft 30 is disposed at the output end of the auxiliary sliding component 29. The auxiliary winding wheel 31 is sleeved on the outside of the auxiliary support shaft 30. The auxiliary sliding component 29 is an electric slide rail. After activation, it drives the auxiliary winding wheel 31 to approach the foreign object. Then, a motor is installed on the auxiliary winding wheel 31, which drives the auxiliary winding wheel 31 to rotate outside the auxiliary support shaft 30, thereby improving the efficiency and effect of winding the foreign object. After winding is completed, the rotation of the auxiliary winding wheel 31 and the winding drive shaft 28 is required to make the infrared emitter 34 receive the infrared rays emitted by the infrared emitter 34. At this time, it means that the first groove 32 and the second groove 33 are aligned. After alignment, it means that the distribution of the rod body of the rotating winding rod 7 and the distribution of the protrusions on the auxiliary winding wheel 31 can be adapted to the subsequent crushing wheel 38. The crushing wheel 38 is perfectly located between the rod body and the protrusions, avoiding collision between the crushing wheel 38 and the rod body and the protrusions when crushing the foreign object.

[0045] Furthermore, please refer to Figures 6 to 8 The crushing telescopic component 36 is disposed on the outside of the second clamping cylinder 5. The output end of the crushing telescopic component 36 is fixedly connected to the arc-shaped plate 37, and multiple crushing wheels 38 are disposed on the arc-shaped plate 37. The crushing telescopic component 36 is a self-locking cylinder. After activation, it drives the arc-shaped plate 37 to approach the flipped winding telescopic frame 26, so that the crushing wheels 38 are positioned between multiple rods and protrusions. At this time, the motor inside the crushing wheel 38 is activated, driving the crushing wheel 38 to rotate, thereby crushing the entangled foreign objects.

[0046] Finally, please see Figure 6 The inclined plate 39 is disposed on the inner bottom wall of the second clamping cylinder 5, and the magnetic slider 40 is disposed below the second clamping cylinder 5. The collection groove 41 is slidably connected to the magnetic slider 40. Crushed foreign objects fall into the collection groove 41 through the opening below the second clamping cylinder 5. Once full, the operator can quickly disassemble the collection groove 41 by sliding it. Simultaneously, when installing the collection groove 41, the magnetic slider 40 can be energized to generate magnetic force, thereby attracting and fixing the metal collection groove 41 to prevent it from falling off. Furthermore, to reduce weight, only the contact area between the collection groove 41 and the magnetic slider 40 is made using advanced technology; other areas are made of high-strength plastic, thus demonstrating the advantages of lightweight drones and saving energy.

[0047] When using the foreign object removal device for power transmission lines based on UAV technology in this embodiment, before the UAV takes off, the insulating mounting block 3 is first installed and fixed to the UAV. The insulating mounting block 3 serves as insulation to ensure the safety of the UAV. The control terminal box 1 sends control commands through connection with the upper system. After the UAV discovers strips of cloth or plastic bags wrapped around the power transmission line during inspection, it activates the clamping drive unit to drive the first clamping cylinder 4 and the second clamping cylinder 5 to move relative to each other, clamping and wrapping the area of ​​the power transmission line with foreign objects attached. Then, the cutting wheel 6 cuts the strips of cloth or plastic bags. Then, the rotating winding rod 7 is activated to wrap the cut strips of cloth or plastic bags around and pull them into the second clamping cylinder 5, so that they are detached from the power transmission line. When the foreign object is clumps of feces, the first clamping cylinder 4 and the second clamping cylinder 5 wrap around the power transmission line and move laterally. The scraper set at the front end of the clamping cylinder scrapes off the clumps of feces. Finally, the first clamping cylinder 4 and the second clamping cylinder 5 release the clamps, and the UAV flies to the next foreign object area for removal.

[0048] With the above-mentioned structural configuration, the area of ​​the transmission line with foreign objects is clamped and wrapped by the first clamping cylinder 4 and the second clamping cylinder 5, thereby reducing the swaying and shaking of the area when clamping or cutting the foreign objects, improving the stability and accuracy of clamping or cutting. At the same time, by wrapping the area with foreign objects before cutting, the foreign objects can also be prevented from being blown away by the strong winds at high altitudes, significantly improving the efficiency and effect of removing foreign objects from high-altitude transmission lines.

[0049] In addition, this application is equipped with a control APP, which can be connected to the control terminal box 1. It can not only realize the operation control of the clamping cylinder, but also monitor the working status of the device in real time, ensuring safety and reliability during operation. It adopts advanced LoRa wireless communication technology and hardware and software dual anti-interference measures, which can ensure the accuracy and stability of data transmission even in complex electromagnetic environments.

[0050] Please see Figure 9 The present invention also provides a method for removing foreign objects from power transmission lines based on unmanned aerial vehicle (UAV) technology, comprising the following steps:

[0051] S1: Install and fix the insulating mounting block 3 to the UAV;

[0052] S2: The control terminal box 1 sends control commands by connecting to the host system;

[0053] S3: Activate the clamping drive unit to drive the first clamping cylinder 4 and the second clamping cylinder 5 to move relative to each other, clamping and wrapping the area of ​​the transmission line with foreign objects attached.

[0054] S4: The cutting wheel 6 cuts the cloth strips or plastic bags;

[0055] S5: The rotating winding rod 7 wraps and pulls the cut strips of cloth or plastic bags into the second clamping cylinder 5, so that they are removed from the power transmission line;

[0056] S6: The first clamping cylinder 4 and the second clamping cylinder 5 are released from clamping, and the drone flies to the next foreign object area for removal.

[0057] The process involves installing and fixing the insulating mounting block 3 to the drone; the control terminal box 1 connecting to the host system to send control commands; activating the clamping drive unit to drive the first clamping cylinder 4 and the second clamping cylinder 5 to move relative to each other, clamping and wrapping the area of ​​the power line with foreign objects attached; the cutting wheel 6 cutting the cloth strips or plastic bags; the rotating winding rod 7 wrapping and pulling the cut cloth strips or plastic bags into the second clamping cylinder 5, detaching them from the power line; the first clamping cylinder 4 and the second clamping cylinder 5 releasing the clamps, and the drone flying to the next foreign object area for removal.
