Description

Technical Field

[0001] This invention belongs to the field of power technology, specifically relating to a grounding device for unmanned aerial vehicle (UAV)-assisted attachment and removal of conductors. Background Technology

[0002] In the operation and maintenance of power systems, drone-based grounding installation and removal is a method that uses drone technology to automate the installation and removal of grounding devices. Its core principle is that ground operators remotely control a drone, using its onboard mechanical gripping or connecting mechanisms to precisely connect the grounding wire or grounding clamp to a designated location on the power line, forming temporary grounding protection. After the operation is completed, the drone safely removes the grounding device.

[0003] This operational method is primarily used in the inspection and maintenance of high-voltage transmission lines. In traditional operations, manually attaching and removing grounding devices requires personnel to climb towers or approach live lines, which is not only physically demanding but also carries a high risk of electric shock. Drone-based grounding technology, however, enables non-contact operation through remote control, significantly improving safety and efficiency while minimizing disruption to the normal operation of power lines. In practice, operators first plan the drone's flight path based on the parameters of the work line and environmental conditions. Then, the drone, carrying the grounding device, takes off and, with the assistance of a positioning system, reaches the target location. A specialized clamp reliably connects the grounding device to the line. After the operation is completed, the drone takes off again to disconnect the grounding device and bring it back to the ground.

[0004] However, in actual operating environments, icing on power lines can significantly impact the normal operation of drones attaching and detaching grounding devices. Ice covering the power line surface makes the line irregular in shape and greatly increases its smoothness. This makes it difficult for the drone-mounted grounding device to establish stable contact with the power line, preventing reliable fixation. Summary of the Invention

[0005] In view of this, the present invention provides a grounding device for drone-assisted attachment and detachment of wires, to solve the problem in the prior art where ice covering the surface of the wire makes the wire irregular in shape and significantly increases the surface smoothness. This makes it difficult for the grounding device carried by the drone to form a stable contact with the wire, thus failing to achieve reliable fixation.

[0006] The technical solution adopted in this invention is as follows:

[0007] A grounding device for drone-assisted attachment and removal of wires includes a hanger, one end of which has a U-shaped structure. A rotating roller is rotatably connected to the inner side of the hanger, and two limiting discs are sleeved on the rotating roller, with the two limiting discs spaced apart.

[0008] It also includes a control rope, one end of which is connected to a terminal block, the other end of which passes over the rotating roller, and the control rope is located between two limit discs. The bottom of the terminal block is provided with a grounding wire.

[0009] The inner side of the hanger is also provided with a liquid tank, and a liquid outlet device is provided on one side of the liquid tank. The liquid outlet device is connected to a liquid outlet pipe, and the liquid outlet end of the liquid outlet pipe extends to the top of the hanger and is connected to a nozzle. The spray nozzle faces downward.

[0010] It also includes a linkage device that drives the limiting plate and the liquid dispensing device. When the limiting plate rotates, the liquid dispensing device is started through the linkage device.

[0011] In this technical solution, it should be noted that the hanger, as the load-bearing frame of the overall device, has a U-shaped structure at one end for securing the device to the conductor, providing stable support. It is made of high-strength aluminum alloy. The limit disc, spaced on the rotating roller, limits the position of the control rope on the roller to prevent deviation. It has a diameter of 9cm and is made of lightweight plastic with a certain degree of rigidity. The control rope transmits ground tension to control the lifting and lowering of the terminal block. The terminal block is made of copper alloy with excellent conductivity to ensure reliable grounding. The liquid tank, with a capacity of 600ml, is used to store de-icing fluid and is made of lightweight polyethylene plastic to reduce the overall weight of the device. The liquid outlet device controls the output of de-icing fluid. The outlet pipe is a low-temperature resistant hose, and the downward-facing nozzle can accurately spray the de-icing fluid onto the surface of the conductor to break up the ice layer. The linkage device is responsible for converting the rotation of the limit disc into the activation of the liquid outlet device, realizing the synchronization of de-icing and the lifting and lowering of the terminal block. The overall working principle is as follows: After the drone lifts the gantry to the designated conductor position, it releases it, and the gantry is secured to the conductor via a U-shaped structure. Ground personnel pull the control rope, which drives a rotating roller to rotate. The rotation of the roller moves the terminal block upwards, and simultaneously, the roller drives a limit plate to rotate. The limit plate triggers a liquid dispensing device via a linkage mechanism, and de-icing fluid is sprayed onto the conductor through a nozzle via a dispensing pipe. Once the terminal block reaches its highest position and grounding is complete, the personnel secure the control rope to the ground. The U-shaped structure, rotating roller, and limit plate ensure stable connection between the device and the conductor, as well as orderly pulling of the control rope. The coordination of the liquid tank, dispensing device, nozzle, and linkage mechanism enables simultaneous de-icing of the conductor during the raising and lowering of the terminal block, solving the problems of unstable device fixation and slippage caused by conductor icing, and improving the reliability and efficiency of drone-assisted grounding operations.

[0012] Preferably, the liquid dispensing device includes a housing located on one side of a liquid tank. An inlet communicating with the liquid tank is provided through the housing, and a first one-way valve is installed inside the inlet. An outlet communicating with a liquid dispensing pipe is also provided through the housing, and a second one-way valve is installed inside the outlet. A piston plate is slidably embedded inside the housing, and a piston rod is fixedly connected to the top of the piston plate. The top of the piston rod extends out of the housing and is connected to a push plate. When the limiting disc rotates, the push plate moves up and down via the linkage device.

[0013] In this technical solution, it should be noted that the housing, as the main structure of the liquid outlet device, provides installation space for internal components. It is made of high-strength engineering plastic with a wall thickness of 2mm to ensure that it is not easily deformed under pressure. The inlet connects the liquid tank and the housing, allowing the de-icing fluid in the liquid tank to enter the housing. The first one-way valve inside only allows the de-icing fluid to flow from the liquid tank to the housing, preventing backflow. The outlet is used to transport the de-icing fluid in the housing to the outlet pipe. The second one-way valve inside only allows the de-icing fluid to flow from the housing to the outlet pipe, preventing backflow of the de-icing fluid back into the housing. The piston plate fits tightly against the inner wall of the housing and can slide up and down inside the housing. By changing the internal volume of the housing, it achieves the intake and discharge of liquid. It is made of rubber and has good sealing performance. The piston rod connects the piston plate and the push plate, which plays a role in force transmission. It is made of stainless steel to ensure sufficient strength. The push plate, as a force-bearing component, receives the power transmitted by the linkage device and drives the piston rod and piston plate to move. When the limit plate rotates, the linkage device drives the push plate to move up and down. When the push plate moves downward, it pushes the piston plate to slide downward in the tank through the piston rod, reducing the volume of the tank and increasing the pressure. This causes the de-icing fluid to open the second one-way valve and enter the outlet pipe from the outlet port. When the push plate moves upward, the piston plate slides upward, creating a negative pressure inside the tank. This opens the first one-way valve, allowing the de-icing fluid in the liquid tank to enter the tank through the inlet port. This cycle repeats to achieve a continuous output of de-icing fluid. By setting up an outlet device consisting of a tank, piston plate, piston rod, push plate, and one-way valve, combined with the linkage device and the limit plate, a quantitative and stable output of de-icing fluid is achieved. This ensures continuous de-icing of the wires during the lifting and lowering of the terminal block, further improving the reliability of the device in icing environments.

[0014] Preferably, the linkage device includes a cam, which is disposed on the side wall of the limiting plate. The end of the cam contacts the top of the push plate. A spring is sleeved on the piston rod, with one end of the spring connected to the push plate and the other end connected to the top of the housing.

[0015] In this technical solution, it should be noted that the cam is fixedly mounted on the side wall of the limiting plate and rotates synchronously with the limiting plate. Its irregular contour can create a periodic squeezing effect on the push plate during rotation. The spring is sleeved on the piston rod, with one end connected to the bottom of the push plate and the other end fixed to the top of the housing, using its own elastic deformation to provide a restoring force. When the limiting plate rotates, the cam rotates with the limiting plate. The convex part of the cam contacts the top of the push plate and squeezes the push plate downward. The push plate drives the piston rod and piston plate to move downward. At this time, the spring is compressed and stores energy, and the de-icing fluid in the housing is discharged through the outlet under the squeezing of the piston plate. When the convex part of the cam rotates away from the push plate, the elastic force of the spring pushes the push plate upward, and the piston rod and piston plate return to their original positions. A negative pressure is formed in the housing, and the de-icing fluid in the liquid tank enters the housing through the inlet. Through the cooperation of the cam and the spring, the continuous rotation of the limiting plate is converted into the reciprocating up and down movement of the push plate, thereby driving the liquid discharge device to work continuously.

[0016] Preferably, there are multiple cams, and the multiple cams are equally spaced along the circumference of the limiting disk.

[0017] In this technical solution, it should be noted that the cooperation of multiple equidistant cams and springs makes the reciprocating motion of the pusher plate more continuous and increases the number of times the piston plate is pushed per unit time. This increases the output frequency of the de-icing fluid, makes the output volume more stable, and can more efficiently remove ice from the wires, further enhancing the operating performance of the device in icing environments.

[0018] Preferably, the bottom of the U-shaped structure of the hanger is rotatably connected to an arc-shaped frame, which is located below the U-shaped structure; the hanger is provided with a first tension spring, one end of which is connected to the arc-shaped frame and the other end of which is connected to the hanger.

[0019] In this technical solution, it should be noted that initially, the arc-shaped frame is positioned below the U-shaped structure under the tension of the first tension spring. When the drone lifts the frame to the conductor position and releases it, the arc-shaped frame first contacts the conductor. Due to the gravity of the entire device, the frame moves downward relative to the conductor. The arc-shaped frame, subjected to the resistance force of the conductor, begins to rotate around the pivot point. The first tension spring is stretched and stores energy. As the arc-shaped frame continues to rotate, its other end gradually rotates downward, eventually closing the lower opening of the U-shaped structure. Through the cooperation of the arc-shaped frame and the first tension spring, the opening can be automatically closed after the frame is inserted into the conductor, effectively preventing the device from falling out of the U-shaped structure due to vibration or conductor movement during operation. This further improves the stability and reliability of the connection between the device and the conductor, ensuring the smooth progress of the grounding operation.

[0020] Preferably, the top of the hanger is provided with a support frame, the support frame is provided with a slider, the hanger is provided with a sliding groove, the sliding groove is vertically arranged, the slider is slidably embedded in the sliding groove, the side wall of the support frame is provided with a lifting ring, and the top of the support frame is provided with a control box; the inner side of the hanger is rotatably connected to a clamping plate by a hinge shaft, the two clamping plates are symmetrically and inclined, and the opposite ends of the two clamping plates are respectively provided with arc-shaped grooves; a rotating plate is fixedly sleeved on each of the two hinge shafts, the two rotating plates are inclined and symmetrical to each other, and the two rotating plates are located below the support frame; the outer side of the hanger is provided with a fixed pulley corresponding to the number of rotating plates, each fixed pulley is located above the corresponding rotating plate, and each rotating plate is provided with a pull rope, the pull rope passing around the corresponding fixed pulley and connecting to the slider.

[0021] In this technical solution, it should be noted that the support frame is made of lightweight, high-strength aluminum alloy, providing an installation base for the control box and lifting ring. The support frame is equipped with a slider made of wear-resistant cast iron. The lifting frame has a vertically positioned groove, the width of which matches the slider. The slider is slidably embedded in the groove, allowing the support frame to slide stably and vertically along the lifting frame. The lifting ring is made of 40Cr alloy steel for connection to the drone. The control box is made of ABS engineering plastic and integrates control components to coordinate the actions of various parts. The clamping plate is made of high-strength manganese steel with an anti-corrosion treatment. The arc-shaped groove has anti-slip textures to increase friction with the wires. The rotating plate is made of Q235 steel plate. When the drone is lifted by the hoisting ring, the support frame is in a high position under the tension of the hoisting rope. When the drone is released from the hoisting frame, the control box moves the support frame and the slider downward along the slide groove due to gravity. The slider pulls the rope to move downward in sync, forcing the rotating plate to rotate around the hinge axis. The rotating plate drives the hinge axis to rotate in sync, which in turn causes the two clamping plates to rotate in opposite directions. The arc groove gradually fits against the wire and clamps and fixes it.

[0022] Preferably, the rotating plate is connected to the hanger via a second tension spring.

[0023] In this technical solution, it should be noted that by using the cooperation between the second tension spring and the rotating plate, the rotating plate and clamping plate can be quickly reset after the operation is completed, thereby improving the reusability of the device and further optimizing the rationality and practicality of the overall structure.

[0024] Preferably, the limiting disc is connected to the rotating roller via a bearing, the limiting disc is fixedly sleeved on the side wall of the bearing, and the bearing is rotatably sleeved on the side wall of the rotating roller. It also includes a one-way rotation component that cooperates with the rotating roller and the bearing. When the control rope is pulled to make the rotating roller rotate in the forward direction, the rotating roller drives the limiting disc to rotate through the one-way rotation component. When the rotating roller rotates in the reverse direction, the limiting disc does not rotate due to the action of the one-way rotation component.

[0025] In this technical solution, it should be noted that when the control rope is pulled to make the rotating roller rotate in the forward direction, the unidirectional rotation component drives the limit plate to rotate via the bearing. When the rotating roller rotates in the reverse direction, the limit plate will not rotate with the rotating roller under the action of the unidirectional rotation component. When the hanger needs to be removed, the operator releases the control rope, and the rotating roller rotates in the reverse direction under the action of gravity of the terminal block, etc. At this time, due to the action of the unidirectional rotation component, the limit plate will not rotate, so the cam and push plate will not interact, the liquid discharge device will stop working, and no de-icing fluid will be sprayed out. Through this setting, unidirectional controllable output of de-icing fluid is achieved. When the grounding device is installed, de-icing fluid can be sprayed normally to remove the ice layer and ensure the stable fixation of the device. When dismantling, the spraying stops, avoiding unnecessary consumption of de-icing fluid and preventing possible interference to the operation during dismantling. This improves the practicality and economy of the device.

[0026] Preferably, the unidirectional rotation assembly includes a ratchet and a pawl. The ratchet is fixedly sleeved on the side wall of the bearing, and the pawl is fixed on the rotating roller by a first bracket, and the pawl and the ratchet cooperate with each other.

[0027] In this technical solution, it should be noted that the ratchet is made of No. 45 steel, which has high hardness after quenching. It is fixedly sleeved on the side wall of the bearing, with its teeth evenly distributed on the circumference for easy engagement with the pawl. The pawl is made of spring steel, which has good elasticity and wear resistance. It is fixed to the roller by a first bracket, one end of which is welded to the side wall of the roller, and the other end is rotatably connected to the pawl by a pin. The pawl and ratchet engage with each other, with the end of the pawl abutting against the teeth of the ratchet. When the control rope is pulled to make the roller rotate forward, the roller drives the first bracket and the pawl to rotate synchronously. The pawl engages in the gap between the teeth of the ratchet, pushing the ratchet to rotate with the roller, which in turn drives the limit plate to rotate through the bearing. When the roller rotates in the reverse direction, the pawl is lifted by the inclined surface of the ratchet teeth and disengages from the ratchet teeth. At this time, the ratchet, bearing, and limit plate do not rotate with the roller. This structure, through the unidirectional transmission characteristics of ratchet and pawl, precisely achieves the rotation of the limiting disc to trigger de-icing when the roller rotates in the forward direction, and the stopping of de-icing when it rotates in the reverse direction. This further optimizes the reliability of unidirectional transmission, ensuring that the de-icing fluid is accurately sprayed when installed and completely shut off when removed, reducing de-icing fluid waste and improving the working stability of the device.

[0028] Preferably, a second bracket is also fixed on the roller, and an elastic pressure plate is provided at the end of the second bracket, with the bottom of the elastic pressure plate contacting the top of the pawl.

[0029] In this technical solution, it should be noted that the elastic pressure plate continuously presses the pawl under its own elastic force, ensuring that the end of the pawl is always in close contact with the teeth of the ratchet. Through the cooperation of the second bracket and the elastic pressure plate, the stability of the cooperation between the pawl and the ratchet is further enhanced, reducing the risk of failure in the unidirectional transmission process, extending the service life of the components, and ensuring the accuracy of the de-icing fluid spray control, so that the device maintains reliable performance during repeated hanging and unhanging operations.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. In this invention, by cooperating the liquid tank, liquid dispensing device, nozzle and linkage device, the wire is de-iced synchronously when the terminal block is raised and lowered, which solves the problem of unstable device fixation and easy slippage caused by wire icing, and improves the reliability and efficiency of UAV-assisted grounding and disconnection operations.

[0032] 2. In this invention, by setting up a liquid outlet device consisting of a housing, piston plate, piston rod, push plate and one-way valve, combined with the linkage device and limit plate, the quantitative and stable output of de-icing fluid is realized, ensuring continuous de-icing of the wires during the lifting and lowering of the terminal block, and further improving the reliability of the device in the freezing environment.

[0033] 3. In this invention, the automatic clamping of the wire is achieved through the cooperation of the support frame, slider, slide groove, clamping plate, rotating plate and pull rope, which further enhances the connection strength between the device and the wire;

[0034] 4. In this invention, the unidirectional rotation component enables unidirectional controllable output of de-icing fluid. When the grounding device is installed, the de-icing fluid can be sprayed out normally to remove the ice layer, ensuring the device is stably fixed. When dismantling, the spraying stops, avoiding unnecessary consumption of de-icing fluid and preventing interference to the operation that may be caused by the spraying during dismantling, thus improving the practicality and economy of the device.

[0052] Example 1.

[0053] like Figures 1-9 As shown, an embodiment of the present invention discloses a grounding device for a drone-assisted attachment and detachment of a wire, including a hanger 1. The top end of the hanger 1 is a U-shaped structure 3. A rotating roller 13 is rotatably connected to the inner side of the hanger 1. Two limiting discs 14 are sleeved on the rotating roller 13, and the two limiting discs 14 are spaced apart.

[0054] It also includes a control rope 6, one end of which is connected to a terminal block 5, the other end of which passes around the rotating roller 13, and the control rope 6 is located between two limit discs 14. The bottom of the terminal block 5 is provided with a grounding wire.

[0055] The inner side of the hanger 1 is also provided with a liquid tank 15, and a liquid outlet device is provided on one side of the liquid tank 15. The liquid outlet device is connected to a liquid outlet pipe 17. The liquid outlet end of the liquid outlet pipe extends to the top of the hanger 1 and is connected to a nozzle 171. The spray nozzle 171 has its spray port facing downward.

[0056] It also includes a linkage device that drives the limiting plate 14 and the liquid dispensing device. When the limiting plate 14 rotates, the liquid dispensing device is started through the linkage device.

[0057] It should be noted that the hanger 1, as the supporting frame of the entire device, has a U-shaped structure at one end to secure the device to the wire 2, providing stable support. It is made of high-strength aluminum alloy. The limiting disc 14 is fitted onto the rotating roller 13 and spaced apart to limit the position of the control rope 6 on the rotating roller 13 and prevent it from deviating. It has a diameter of 9cm and is made of lightweight plastic with a certain degree of rigidity. The control rope 6 is used to transmit ground tension to control the lifting and lowering of the terminal block 5. The terminal block 5 is made of copper alloy with excellent conductivity to ensure reliable grounding. The liquid tank 15 is used to store de-icing fluid with a capacity of 600ml. It is made of lightweight polyethylene plastic to reduce the overall weight of the device. The liquid outlet device can control the output of de-icing fluid. The liquid outlet pipe 17 is a low-temperature resistant hose. The nozzle 171 is set downward to accurately spray the de-icing fluid onto the surface of the wire 2 to break the ice layer. The linkage device is responsible for converting the rotation of the limiting disc 14 into the activation of the liquid outlet device, realizing the synchronization of de-icing and the lifting and lowering of the terminal block 5. The overall working principle is as follows: After the drone lifts the hanger 1 to the designated position of the conductor 2, it releases it. The hanger 1 is then secured to the conductor 2 via a U-shaped structure. Ground personnel pull the control rope 6, which drives the rotating roller 13 to rotate. The rotation of the rotating roller 13 moves the terminal block 5 upward, and simultaneously, the rotating roller 13 drives the limiting plate 14 to rotate. The limiting plate 14 triggers the liquid dispensing device through a linkage device, and de-icing fluid is sprayed onto the conductor 2 through the dispensing pipe 17 and nozzle 171. Once the terminal block 5 reaches its highest position and grounding is completed, the personnel fix the control rope 6 to the ground. By setting up the U-shaped structure, rotating roller 13, and limiting plate 14, the stable cooperation between the device and the conductor 2 and the orderly pulling of the control rope 6 are ensured. Through the cooperation of the liquid tank 15, the liquid dispensing device, the nozzle 171, and the linkage device, the conductor 2 is de-iced simultaneously when the terminal block 5 is raised and lowered, solving the problem of unstable device fixation and slippage caused by icing of the conductor 2, and improving the reliability and efficiency of drone-assisted grounding operations.

[0058] Example 2.

[0059] like Figures 7-9As shown, this embodiment is largely the same as the above embodiment, except that the liquid outlet device includes a housing 16 located on one side of the liquid tank 15. The housing 16 has a liquid inlet communicating with the liquid tank 15, and a first one-way valve 151 is provided inside the liquid inlet. The housing 16 also has a liquid outlet communicating with the liquid outlet pipe 17, and a second one-way valve 161 is provided inside the liquid outlet. A piston plate 162 is slidably embedded inside the housing 16, and a piston rod 163 is fixedly connected to the top of the piston plate 162. The top of the piston rod 163 extends out of the housing 16 and is connected to a push plate 164. When the limiting plate 14 rotates, the push plate 164 moves up and down through the linkage device. It should be noted that the housing 16, as the main structure of the liquid outlet device, provides installation space for internal components. It is made of high-strength engineering plastic with a wall thickness of 2mm to ensure it is not easily deformed under pressure. The inlet connects the liquid tank 15 and the housing 16, allowing the de-icing fluid in the liquid tank 15 to enter the housing 16. The first one-way valve 151 inside the inlet only allows de-icing fluid to flow from the liquid tank 15 to the housing 16, preventing backflow. The outlet is used to deliver the de-icing fluid in the housing 16 to the outlet pipe 17. The second one-way valve 161 inside the outlet only allows de-icing fluid to flow from the outlet pipe 17 to the outlet pipe 18. The liquid flows from the tank 16 to the outlet pipe 17 to prevent the de-icing fluid from flowing back into the tank 16. The piston plate 162 fits tightly against the inner wall of the tank 16 and can slide up and down inside the tank 16. By changing the internal volume of the tank 16, the liquid is drawn in and discharged. It is made of rubber and has good sealing performance. The piston rod 163 connects the piston plate 162 and the push plate 164 and plays a role in force transmission. It is made of stainless steel to ensure sufficient strength. The push plate 164 is a force-bearing component, receiving the power transmitted by the linkage device and driving the piston rod 163 and the piston plate 162 to move. When the limit plate 14 rotates, the linkage device drives the push plate 164 to move up and down. When the push plate 164 moves downward, it pushes the piston plate 162 to slide downward in the housing 16 through the piston rod 163. The volume of the space inside the housing 16 decreases, and the pressure increases, causing the de-icing fluid to open the second one-way valve 161 and enter the outlet pipe 17 from the outlet. When the push plate 164 moves upward, the piston plate 162 slides upward accordingly, creating a negative pressure inside the housing 16. The first one-way valve 151 is opened, and the de-icing fluid in the liquid tank 15 enters the housing 16 through the inlet. This process is repeated to achieve continuous output of de-icing fluid. By setting up an outlet device composed of the housing 16, piston plate 162, piston rod 163, push plate 164, and one-way valve, combined with the linkage device and the limit plate 14, a quantitative and stable output of de-icing fluid is achieved, ensuring continuous de-icing of the wire 2 during the lifting and lowering of the terminal block 5, further improving the reliability of the device in icing environments.

[0060] like Figures 7-9As shown, in this embodiment, the linkage device includes a cam 147, which is disposed on the side wall of the limiting disk 14. The end of the cam 147 contacts the top of the push plate 164. A spring 165 is sleeved on the piston rod, with one end of the spring 165 connected to the push plate 164 and the other end connected to the top of the housing 16. It should be noted that the cam 147 is fixedly disposed on the side wall of the limiting disk 14 and rotates synchronously with the limiting disk 14. Its irregular contour can form a periodic squeezing effect on the push plate 164 during rotation. The spring 165 is sleeved on the piston rod 163, with one end connected to the bottom of the push plate 164 and the other end fixed to the top of the housing 16, using its own elastic deformation to provide a restoring force. When the limiting plate 14 rotates, the cam 147 rotates together with the limiting plate 14. The protruding part of the cam 147 contacts the top of the push plate 164 and presses the push plate 164 downward. The push plate 164 drives the piston rod 163 and piston plate 162 to move downward. At this time, the spring 165 is compressed and stores energy. The de-icing fluid in the housing 16 is discharged through the outlet under the pressure of the piston plate 162. When the protruding part of the cam 147 rotates away from the push plate 164, the elastic force of the spring 165 pushes the push plate 164 to move upward. The piston rod 163 and piston plate 162 then return to their original positions, and a negative pressure is formed in the housing 16. The de-icing fluid in the liquid tank 15 enters the housing 16 through the inlet. Through the cooperation of the cam 147 and the spring 165, the continuous rotation of the limiting plate 14 is converted into the reciprocating up and down movement of the push plate 164, thereby driving the liquid outlet device to work continuously.

[0061] like Figure 8 As shown, in this embodiment, there are multiple cams 147, which are equidistantly spaced along the circumference of the limiting disk 14. It should be noted that the multiple equidistant cams 147, in conjunction with the spring 165, make the reciprocating motion of the push plate 164 more continuous, increasing the number of times the piston plate 162 is pushed per unit time. This increases the output frequency of the de-icing fluid, making the output more stable and enabling more efficient removal of ice from the wire 2, further enhancing the device's performance in icing environments.

[0062] Example 3.

[0063] like Figures 1-5As shown, this embodiment is largely the same as the above embodiment, except that an arc-shaped frame 4 is rotatably connected to the bottom of the U-shaped structure 3 of the hanger 1, and the arc-shaped frame 4 is located below the U-shaped structure 3; a first tension spring 23 is provided on the hanger 1, one end of the first tension spring 23 is connected to the arc-shaped frame 4, and the other end is connected to the hanger 1. It should be noted that, in the initial state, the arc-shaped frame 4 is located below the U-shaped structure under the tension of the first tension spring 23. When the drone lifts the hanger 1 to the position of the wire 2 and releases it, the arc-shaped frame 4 first contacts the wire 2. Due to the gravity of the entire device, the hanger 1 moves downward relative to the wire 2, and the arc-shaped frame 4 begins to rotate around the rotation point under the resistance of the wire 2. The first tension spring 23 is stretched and stores force. As the arc-shaped frame 4 continues to rotate, its other end gradually rotates downward, eventually closing the lower opening of the U-shaped structure with the rotated arc-shaped frame 4. With the cooperation of the arc frame 4 and the first tension spring 23, the opening can be automatically closed after the hanger 1 is inserted into the wire 2, which effectively prevents the device from falling out of the U-shaped structure due to vibration or the shaking of the wire 2 during operation, further improving the stability and reliability of the connection between the device and the wire 2, and ensuring the smooth progress of the grounding operation.

[0064] like Figure 6As shown, in this embodiment, the top of the hanger 1 is provided with a support frame 8, the support frame 8 is provided with a slider 18, the hanger 1 is provided with a sliding groove 19, the sliding groove 19 is vertically arranged, the slider 18 is slidably embedded in the sliding groove 19, the side wall of the support frame 8 is provided with a lifting ring 9, and the top of the support frame 8 is provided with a control box 7; the inner side of the hanger 1 is rotatably connected to a clamping plate 10 through a hinge shaft 21, the two clamping plates 10 are symmetrical and inclined, and the opposite ends of the two clamping plates 10 are respectively provided with an arc-shaped groove 12; a rotating plate 20 is fixedly sleeved on the two hinge shafts 21, the two rotating plates 20 are inclined and symmetrical to each other, and the two rotating plates 20 are located below the support frame 8; the outer side of the hanger 1 is provided with a fixed pulley 25 corresponding to the number of rotating plates 20, each fixed pulley 25 is located above the corresponding rotating plate 20, and each rotating plate 20 is provided with a pull rope 24, the pull rope 24 passes around the corresponding fixed pulley 25 and connects to the slider 18. It should be noted that the support frame 8 is made of lightweight, high-strength aluminum alloy, providing an installation base for the control box 7 and the lifting ring 9. The support frame 8 is equipped with a slider 18, which is made of wear-resistant cast iron. The hanging frame 1 is equipped with a vertically oriented groove 19, the width of which is adapted to the slider 18. The slider 18 is slidably embedded in the groove 19, allowing the support frame 8 to slide stably and vertically along the hanging frame 1. The lifting ring 9 is made of 40Cr alloy steel and is used for connection with the drone. The control box 7 is made of ABS engineering plastic and integrates control components to coordinate the actions of various parts. The clamping plate 10 is made of high-strength manganese steel with an anti-corrosion surface treatment. The arc-shaped groove 12 has anti-slip textures to increase friction with the wire 2. The rotating plate 20 is made of Q235 steel plate. When the drone lifts the gantry 1 via the lifting ring 9, the support frame 8 is in a high position under the tension of the lifting rope. When the drone releases the gantry 1, the control box 7 moves the support frame 8 and the slider 18 downward along the slide groove 19 due to gravity. The slider 18 pulls the pull rope 24 downward synchronously, forcing the rotating plate 20 to rotate around the hinge shaft 21. The rotating plate 20 drives the hinge shaft 21 to rotate synchronously, thereby causing the two clamping plates 10 to rotate in opposite directions. The arc groove 12 gradually fits against the wire 2 and clamps and fixes it.

[0065] like Figure 6 As shown, in this embodiment, the rotating plate 20 is connected to the hanger 1 via a second tension spring 22. It should be noted that the cooperation between the second tension spring 22 and the rotating plate 20 helps the rotating plate 20 and the clamping plate 10 to quickly reset after operation, improving the reusability of the device and further optimizing the rationality and practicality of the overall structure.

[0066] Example 4.

[0067] like Figures 7-9As shown, this embodiment is largely the same as the above embodiment, except that the limiting disc 14 is connected to the rotating roller 13 via a bearing 141. The limiting disc 14 is fixedly sleeved on the side wall of the bearing 141, and the bearing 141 is rotatably sleeved on the side wall of the rotating roller 13. It also includes a one-way rotation assembly that cooperates with the rotating roller 13 and the bearing 141. When the control rope 6 is pulled to make the rotating roller 13 rotate forward, the rotating roller 13 drives the limiting disc 14 to rotate via the one-way rotation assembly. When the rotating roller 13 rotates in the reverse direction, the limiting disc 14 does not rotate due to the action of the one-way rotation assembly. It should be noted that when the control rope 6 is pulled to make the rotating roller 13 rotate forward, the one-way rotation assembly, in turn, drives the limiting disc 14 to rotate via the bearing 141; when the rotating roller 13 rotates in the reverse direction, the one-way rotation assembly prevents the limiting disc 14 from rotating with the rotating roller 13. When the hanger 1 needs to be removed, the operator releases the control rope 6. The rotating roller 13 rotates in the opposite direction under the weight of the terminal block 5. At this time, due to the unidirectional rotation component, the limit plate 14 will not rotate, so the cam 147 and push plate 164 will not interact, the liquid outlet device stops working, and no de-icing fluid is sprayed out. This design achieves unidirectional controllable output of de-icing fluid. When the grounding device is installed, de-icing fluid can be sprayed normally to remove ice, ensuring the device's stable fixation. During dismantling, the spraying stops, avoiding unnecessary consumption of de-icing fluid and preventing potential interference with operations during dismantling, thus improving the device's practicality and economy.

[0068] like Figure 8As shown, in this embodiment, the unidirectional rotation assembly includes a ratchet 142 and a pawl 143. The ratchet 142 is fixedly sleeved on the side wall of the bearing 141, and the pawl 143 is fixed on the roller 13 via a first bracket 144, and the pawl 143 and ratchet 142 cooperate with each other. It should be noted that the ratchet 142 is made of 45# steel, which has high hardness after quenching treatment. It is fixedly sleeved on the side wall of the bearing 141, and its teeth are evenly distributed on the circumference, which facilitates cooperation with the pawl 143. The pawl 143 is made of spring steel 165, which has good elasticity and wear resistance. It is fixed on the roller 13 via the first bracket 144. One end of the first bracket 144 is welded to the side wall of the roller 13, and the other end is rotatably connected to the pawl 143 via a pin, and the pawl 143 and ratchet 142 cooperate with each other, with the end of the pawl 143 abutting against the teeth of the ratchet 142. When the control rope 6 is pulled, causing the rotating roller 13 to rotate in the forward direction, the rotating roller 13 drives the first support 144 and the pawl 143 to rotate synchronously. The pawl 143 engages in the tooth gap of the ratchet 142, pushing the ratchet 142 to rotate with the rotating roller 13, which in turn drives the limiting disk 14 to rotate through the bearing 141. When the rotating roller 13 rotates in the reverse direction, the pawl 143 is lifted by the inclined surface of the ratchet 142 teeth and disengages from the ratchet 142 teeth. At this time, the ratchet 142, the bearing 141, and the limiting disk 14 do not rotate with the rotating roller 13. This structure, through the unidirectional transmission characteristics of the ratchet 142 and the pawl 143, precisely realizes that when the rotating roller 13 rotates in the forward direction, it drives the limiting disk 14 to rotate to trigger de-icing, and when it rotates in the reverse direction, the limiting disk 14 remains stationary to stop de-icing. This further optimizes the reliability of unidirectional transmission, ensures that the de-icing fluid is accurately sprayed when installed and completely shut off when removed, reduces the waste of de-icing fluid, and improves the working stability of the device.

[0069] like Figure 8 As shown, in this embodiment, a second bracket 146 is also fixed on the rotating roller 13. An elastic pressure plate 145 is provided at the end of the second bracket 146, and the bottom of the elastic pressure plate 145 contacts the top of the pawl 143. It should be noted that the elastic pressure plate 145 continuously presses the pawl 143 under its own elastic force, ensuring that the end of the pawl 143 always closely contacts the teeth of the ratchet 142. Through the cooperation of the second bracket 146 and the elastic pressure plate 145, the stability of the cooperation between the pawl 143 and the ratchet 142 is further enhanced, reducing the risk of failure in the unidirectional transmission process, extending the service life of the components, and ensuring the accuracy of the de-icing fluid spray control, enabling the device to maintain reliable performance during repeated hanging and unhanging operations.

[0070] The working principle of this invention is as follows:

[0071] During operation, the drone connects to the support frame 8 via the lifting ring 9, lifting the entire device and transporting it to the designated position of the guide wire 2. At this time, the support frame 8 is in a high position under the tension of the lifting rope, the second tension spring 22 is in a naturally extended state, the two V-shaped rotating plates 20 maintain their initial opening angle, and the arc frame 4 is located below the U-shaped structure under the tension of the first tension spring 23. After reaching the position, the drone releases the lifting ring 9, and the device falls under the action of gravity. The arc frame 4 first contacts the guide wire 2. As the device continues to fall, the arc frame 4 rotates around the rotation point under the contact force of the guide wire 2, and the first tension spring 23 is stretched. Finally, the arc frame 4 closes the opening below the U-shaped structure. Simultaneously, the control box 7 drives the support frame 8 and slider 18 to slide downwards along the slide groove 19. The slider 18 is stably guided within the slide groove 19, and by driving the pull rope 24 downwards, the rotating plate 20 rotates around the hinge axis 21 and drives the clamping plate 10 to rotate. The second tension spring 22 is stretched, and the two clamping plates 10 clamp and fix the wire 2 through the arc groove 12. Then, the ground staff pulls the control rope 6. Under the limit of the two limit discs 14, the control rope 6 drives the rotating roller 13 to rotate in the forward direction. The rotating roller 13 drives the pawl 143 to rotate through the first bracket 144. The elastic pressure plate 145 presses the pawl 143 to make it tightly mesh with the ratchet 142, pushing the ratchet 142. 42. Bearing 141 and limiting plate 14 rotate synchronously. Multiple equidistant cams 147 rotate with the limiting plate 14, sequentially pressing the push plate 164. The push plate 164 drives the piston rod 163 and piston plate 162 to move downward, compressing the spring 165. The de-icing fluid in the housing 16 opens the second one-way valve 161 and sprays onto the surface of the wire 2 through the outlet pipe 17 and nozzle 171. After the cam 147 rotates away, the spring 165 pushes the push plate 164 to reset, and the piston plate 162 moves upward, creating a negative pressure in the housing 16. The first one-way valve 151 opens, and the de-icing fluid in the liquid tank 15 is replenished to the housing 16 through the inlet. This process is repeated to achieve continuous de-icing. As the control rope 6 is pulled... As the terminal block 5 gradually rises to contact the wire 2, grounding is completed, and the operator secures the control rope 6. After the operation is completed, the drone lifts the device again, the support frame 8 moves upward, the second tension spring 22 pulls the rotating plate 20 and the clamping plate 10 to reset, the operator releases the control rope 6, and the gravity of the terminal block 5 drives the rotating roller 13 to rotate in the opposite direction. At this time, the pawl 143 is lifted by the inclined surface of the ratchet 142 teeth and disengages from the ratchet 142. The limit plate 14 stops rotating, the cam 147 no longer squeezes the push plate 164, the liquid dispensing device stops spraying liquid, and at the same time, the arc frame 4 resets under the action of the first tension spring 23 and opens the U-shaped structure opening. The device is then disengaged from the wire 2 and dismantled.
