Description

Technical Field

[0001] The present invention belongs to the technical field of high-altitude cable obstacle removal, and in particular relates to a method for removing combustible foreign matter from cables based on electric heating wire hot melting technology. Background Art

[0002] Foreign objects (such as kites and plastic bags) hanging from overhead cables (e.g., high-voltage and telecommunication cables) can cause safety hazards such as short circuits and fires, threatening public safety and the normal operation of power and telecommunication systems. For example, clearing overhead transmission lines requires workers to work at height, which is not only extremely dangerous but also often requires power outages, disrupting user life and productivity. Currently, existing technologies for clearing overhead cables are crucial in the power and telecommunication sectors. Research at home and abroad has primarily focused on traditional clearance methods, mechanical equipment, drones, and lasers.

[0003] Traditional towing methods: Early towing work was mostly done manually, which was not only labor-intensive and inefficient, but also highly dangerous.

[0004] Mechanical obstacle removal equipment: To improve obstacle removal efficiency and safety, a variety of mechanical obstacle removal equipment has emerged. For example, in 2021, the Pingyuan County Power Supply Company of the State Grid Shandong Electric Power Company invented a barrier removal device for high-altitude cables. The device includes a shell with cutting blades and propellers, which allows users to easily remove debris on the cable and surrounding vegetation. In 2024, Changdafeng Electric Power Technology Co., Ltd. obtained a patent for "A De-icer for High-Altitude Cable Operation and Maintenance." This device uses a new mobile de-icing structure and the propulsion of the mobile drive component on the cable surface to ensure that the ice on the entire cable surface is completely melted.

[0005] Drone Obstacle Removal: Using drones equipped with tools for obstacle removal has been a research hotspot in recent years. Drones offer flexibility and efficiency, eliminating the risks of manual clearance. For example, some drones equipped with cutting tools and flamethrowers are used to clear debris from overhead cables. However, drone-based obstacle removal also presents challenges such as significant environmental impact and limited payload capacity.

[0006] Laser obstacle removal: Laser obstacle removal technology has the advantages of long distance and non-contact, and can effectively remove foreign objects from high-altitude cables. In 2024, Leshan Electric Power Jiajiang Company used laser obstacle removal technology for the first time in power line maintenance, and successfully cleared the problem of plastic bags entangled on the 45th pole of the 35kV Xingan Line in Ganjiang Town, Jiajiang County. The staff used the APP control system on the tablet to launch a laser, and the foreign objects instantly caught fire and fell, effectively eliminating the hidden dangers of electricity. Compared with the traditional manual cleaning method of climbing the pole during power outages, laser obstacle removal is safe and efficient, and does not require power outages, which can ensure safer operation of the power grid. However, laser obstacle removal requires aiming every time it is cleared, and its efficiency will be reduced when there are more debris on the cables. Summary of the Invention

[0007] The purpose of the present invention is to provide a method for removing combustible foreign matter from cables based on electric heating wire hot melting technology, which has a scientific principle, is easy to operate, safe and efficient.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a method for removing combustible foreign matter from cables based on electric heating wire hot melting technology, comprising the following steps: S1. Remotely operate the hot melt self-propelled device to unfold on the ground and keep it in a ready-to-hang line state; S2. Operate the drone to lift and deploy the hot melt self-propelled device onto the high-altitude cable; S3, remote control operation of the hot melt self-propelled device to transform into a working state; S4, the drone is separated from the hot melt self-propelled device; S5. The hot melt self-propelled device starts to remove the combustible foreign matter on the high-altitude cables; S6. After the cleaning operation is completed, the drone is controlled to recover the hot melt self-propelled device from high altitude to the ground.

[0009] The hot melt self-propelled device includes a left mounting frame and a right mounting frame, which are transparent from front to back, open downward, and have an overall inverted V-shaped structure. Front rollers and rear rollers are provided between the upper parts of the left mounting frame and the right mounting frame. The outer circles of the front rollers and the rear rollers are provided with an annular wheel groove that is wide on the outside and narrow on the inside. The inner wall of the annular wheel groove is provided with a friction structure. The right mounting frame is provided with a walking motor for driving the front roller and / or the rear roller. A lifting ring is provided at the middle part of the upper end of the left mounting frame and the right mounting frame. A horizontal rotating hot melt device is provided on the front side of the left mounting frame, a vertical rotating hot melt power supply is provided in the middle of the right mounting frame, and a walking battery for powering the walking motor is provided at the lower part of the rear side of the left mounting frame. Mounting frames are provided above the front rollers on the left mounting frame and the right mounting frame, and a high-definition camera and an image wireless transmission module are provided on the mounting frame. Electrical components are provided on the left side of the left mounting frame.

[0010] The horizontal rotary hot melt device includes a horizontal rotary motor installed on the left mounting frame. The main shaft of the horizontal rotary motor is connected to a horizontal mounting plate. A ducted fan and two hot melt supports symmetrical about the ducted fan are installed on the horizontal mounting plate. Each hot melt support is connected to a hot melt fork frame through two pins spaced apart upper and lower. The two hot melt forks extend forward and upward. Ceramic blocks are provided at both ends of the hot melt fork frame. A ceramic rod parallel to the horizontal mounting plate is provided between the two ceramic blocks. Electric heating wire is wound on the ceramic rod. The winding density of the electric heating wire on the ceramic rod is large in the middle and small on both sides.

[0011] The vertical rotating hot melt power supply includes a rotating frame, a hot melt battery and a vertical rotating motor. The vertical rotating motor is fixed in the middle of the right mounting frame. The main shaft of the vertical rotating motor is arranged horizontally front and back. The main shaft of the vertical rotating motor is connected to the rotating frame, and the hot melt battery is arranged on the rotating frame.

[0012] The high-definition camera is rotatably connected to the mounting frame through the left and right horizontal rotating shafts. The mounting frame is provided with a camera adjustment motor, and the main shaft of the camera adjustment motor is connected to the rotating shaft; The electrical components include a wireless receiver, an electronic speed regulator and a relay module. The wireless receiver is used to receive signal instructions from the hot melt on the ground. The signal output end of the wireless receiver is respectively connected to the horizontal rotation motor, vertical rotation motor, walking motor, camera adjustment motor, electronic speed regulator and relay module. The electronic speed regulator is used to adjust the speed of the ducted fan. The relay module is connected to the heating wire. The high-definition camera is connected to the display screen on the hot melt remote control through the image wireless transmission module.

[0013] The specific process of step S1 is: first start the horizontal rotating motor, the horizontal rotating motor drives the horizontal rotary hot melt device to rotate 90° from the front to the left, so that the V-shaped groove between the left mounting frame and the right mounting frame is transparent and unobstructed front and back, so as to facilitate the passage of high-altitude cables. In order to keep the balance of the hot melt self-propelled device, start the vertical rotating motor to drive the horizontal rotary hot melt device and the vertical rotary hot melt power supply to rotate to the right. The vertical rotary hot melt power supply acts as a counterweight to maintain the balance between the left and right.

[0014] The specific process of step S2 is as follows: the drone hangs the lifting ring with a rope, controls the drone to lift the hot melt self-propelled device and transport it above the high-altitude cable, and then slowly lowers it until the high-altitude cable extends into the annular wheel grooves of the front and rear rollers; The specific process of step S4 is: the hook of the drone is separated from the lifting ring on the upper part of the hot-melt self-propelled device.

[0015] The specific process of step S3 is: start the horizontal rotating motor and the vertical rotating motor at the same time, and rotate the horizontal rotating hot melt device 90° from the right front, that is, the horizontal rotating hot melt device is restored to its original position, located in front of the left mounting frame and the right mounting frame, and the vertical rotating motor and the vertical rotating hot melt power supply are folded upward to fit with the right mounting frame. At this time, the center of gravity of the entire hot melt self-propelled device is in the same plane as the overhead cable.

[0016] The specific process of step S5 is as follows: the operator controls the hot melt remote control on the ground, opening and closing the control to each component through the wireless receiver. First, the travel motor is started. The two travel motors rotate synchronously at the same speed, driving the front and rear rollers to move forward on the overhead cable. The high-definition camera transmits the situation on the overhead cable to the hot melt display screen through the image wireless transmission module. When the operator sees an obstacle such as a plastic bag on the overhead cable on the lower screen and the heating wire touches the plastic bag, the travel motor stops and the hot melt self-propelled device pauses. Then the relay module is activated, the heating wire is energized, and the heating wire heats up and melts the obstacle. The relay module is then closed, and the ducted fan is started again. The high-pressure air blown by the ducted fan blows off the part still hanging on the overhead cable. If the wind force is insufficient, the ducted fan speed is adjusted through the electronic speed regulator. The ducted fan is turned off, and the travel motor is started again. The front and rear rollers continue to move forward on the overhead cable, and the above hot melt obstacle removal process is repeated.

[0017] Step S6 specifically involves starting the drone, using its hook to hook onto the upper ring of the hot melt self-propelled device, keeping the drone stationary in the air. The hot melt remote controller then simultaneously activates the horizontal and vertical motors, rotating the horizontal hot melt device 90° to the left and rear, deploying it to the left. The vertical motor then rotates the vertical hot melt power supply downward, maintaining the balance of the entire hot melt self-propelled device. Finally, the drone is started again, lifting the hot melt self-propelled device above the overhead cable, then flying left or right, before landing at the designated location.

[0018] Using the above technical solution, the present invention first utilizes a commercially available drone. The drone, serving as the transport vehicle, is responsible for precisely deploying the drone onto the cable and recovering it upon completion. The drone utilizes high-precision positioning technology to ensure accurate deployment. Furthermore, the drone is equipped with an obstacle avoidance system to prevent collisions with cables or other obstacles during flight. The drone is suspended by a rope from the present invention's lifting ring, which can also serve as a handle for convenient hand-carrying.

[0019] Compared with the prior art, the present invention has the following innovations and beneficial effects: 1. The horizontally rotating hot melt device has the ability to rotate left and right. Because the hot melt device must be placed below the cable for hot melt cutting and can be deployed and recovered by drone, a deformable structure (horizontal rotation) is required to achieve front-to-back transparency in the V-shaped path during deployment. This means the hot melt device needs to move out of the way. To ensure the levelness of the suspended trolley, the right-hand vertically rotating hot melt power source needs to deform (rotate) to achieve center of gravity balance.

[0020] 2. A thin heating wire is used as the heater. This wire heats up quickly, reaching temperatures sufficient for cutting common flammable foreign objects. It also consumes little power, allowing for extended operation. Precise temperature control of the heating resistor prevents fires during the cutting process. Drone deployment and recovery eliminates the risk of electric shock and falls associated with manual operation.

[0021] 3. Use a ceramic rod to support a thin heating wire. As the heating wire heats up, it becomes longer and softer, causing the cutting position to shift and becoming easily damaged. Wrapping the heating wire around a ceramic rod effectively solves this problem.

[0022] 4. Innovation in the winding form of the heating wire. The winding method is dense in the middle and sparse on both sides. The dense winding method is mainly to make it easier to contact and cut combustible foreign matter. The sparse winding method is to shorten the heating time and improve the hot melt efficiency.

[0023] 5. The HD camera can be adjusted in pitch and tilt, allowing for remote monitoring of obstacles on overhead cables and convenient operation of the hot melt remote control. The HD camera supports real-time image transmission, ensuring accurate obstacle recognition. Image recognition algorithm: Based on deep learning technology, a foreign object recognition model is trained with recognition accuracy ≥ 95%. Positioning system: Combining the camera with GPS positioning technology, the system precisely locates foreign objects to ensure cutting accuracy.

[0024] 6. The use of ducted fans can blow away the remaining foreign matter after hot melting from the cables.

[0025] 7. Each hot melt support is connected to a hot melt fork frame through two pins set at intervals above and below. When not in use, the lower pin can be pulled out, and the upper pin can be used as a fulcrum to rotate the hot melt fork frame to the upper right and fit it into the left mounting frame, which saves more space.

[0026] In summary, this invention combines drone technology with intelligent identification and temperature control to achieve intelligent, automated, and safe high-altitude cable clearance. Its innovative design and technological advantages address the high risks and low efficiency of traditional clearance methods, offering significant social and economic benefits, making it suitable for rapid maintenance needs in fields such as power and communications.
