Description

Technical Field

[0001] The present invention belongs to the field of electric power technology, and in particular relates to a conductor grounding device for assisting the hanging and dismantling of an unmanned aerial vehicle. Background Art

[0002] In power system maintenance, drone-based grounding installation and removal utilizes drone technology to automate the installation and removal of grounding devices. The core principle is that a ground operator remotely controls a drone, using the drone's onboard mechanical gripping or connection mechanism to precisely connect a grounding wire or grounding clamp to a specific location on the power line, creating temporary grounding protection. Once the operation is complete, the drone can then safely remove the grounding device. This method of operation is primarily used in the inspection and maintenance of high-voltage transmission lines. Traditionally, manually attaching and removing grounding devices requires workers to climb towers or approach live lines, which is not only labor-intensive but also carries a high risk of electric shock. Drone-based grounding technology, however, enables contactless operations through remote control, significantly improving safety and efficiency while minimizing the impact on the normal operation of power lines. During the operation, the operator first plans the drone's flight path based on the parameters and environmental conditions of the operating line. The drone then launches, carrying the grounding device, and, with the assistance of a positioning system, reaches the target location, where it securely connects the grounding device to the line using a specialized clamp. Once the operation is complete, the drone launches again, disconnects the grounding device, and brings it back to the ground. However, in real-world operating environments, ice formation on power lines can significantly impact the proper operation of drone grounding devices. Ice covering the wires can cause irregularities in their shape and significantly reduce their surface smoothness. This can make it difficult for the drone's grounding device to establish stable contact with the wires, preventing reliable attachment. Summary of the Invention

[0003] In light of this, the present invention provides a drone-assisted wire grounding device to address the existing problem of ice covering the wire surface, causing the wire's shape to become irregular and significantly increasing its surface smoothness. This makes it difficult for the drone-mounted grounding device to establish stable contact with the wire, preventing reliable fixation.

[0004] The technical solution adopted in the present invention is as follows: A wire grounding device for drone-assisted hanging and removal includes a hanger, one end of the top of the hanger is a U-shaped structure, the inner side of the hanger is rotatably connected to a roller, and two limit plates are sleeved on the roller, and the two limit plates are spaced apart; It also includes a control rope, one end of which is connected to a wiring seat, the other end of which is passed around a rotating roller, and the control rope is located between two limit plates, and a ground wire is provided at the bottom of the wiring seat; A liquid tank is further provided on the inner side of the hanger, 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 above the hanger and is connected to a nozzle, and the liquid spraying port of the nozzle faces downward; It also includes a linkage device, which drives the limit plate and the liquid discharge device. When the limit plate rotates, the liquid discharge device is driven to start through the linkage device.

[0005] In this technical solution, it should be noted that the hanger serves as the bearing frame of the entire device, and the U-shaped structure at one end of its top is used to clamp the device on the conductor to provide stable support for the device. It is made of high-strength aluminum alloy; the limit disk is mounted on the roller and is arranged at intervals to limit the position of the control rope on the roller to prevent it from deviating. It has a diameter of 9 cm and is made of plastic, which is light and has a certain rigidity; the control rope is used to transmit 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 is used to store deicing liquid, has a capacity of 600 ml, and is made of lightweight polyethylene plastic to reduce the overall weight of the device; the liquid outlet device can control the output of the deicing liquid, and the liquid outlet pipe is a low-temperature resistant hose. The nozzle is set downward to spray the deicing liquid accurately on the surface of the conductor to break the ice layer; the linkage device is responsible for converting the rotation of the limit disk into the start-up of the liquid outlet device, so as to achieve synchronization between deicing and lifting of the terminal block. The overall working principle is as follows: the drone lifts the hanger to the designated conductor position and then releases it. The hanger is locked on the conductor through a U-shaped structure. The ground staff pulls the control rope, which drives the roller to rotate. The rotation of the roller causes the terminal block to move upward. At the same time, the roller drives the limit plate to rotate. The limit plate triggers the liquid outlet device through the linkage device to start. The deicing liquid is sprayed from the nozzle through the liquid outlet pipe onto the conductor. When the terminal block rises to the highest position and completes grounding, the staff fixes the control rope to the ground. By setting up the U-shaped structure, rollers, and limit plates, the stable coordination between the device and the conductor and the orderly pulling of the control rope are guaranteed. Through the coordination of the liquid tank, liquid outlet device, nozzle, and linkage device, the conductor is de-iced synchronously when the terminal block is raised and lowered, solving the problem of unstable fixation and easy slipping of the device caused by conductor icing, and improving the reliability and efficiency of the drone-assisted hanging and disassembly grounding operation.

[0006] Preferably, the liquid outlet device includes a box body, which is located on one side of the liquid tank, and a liquid inlet connected to the liquid tank is penetrated on the box body, and a first one-way valve is provided in the liquid inlet. The box body is also penetrated by a liquid outlet connected to the liquid outlet pipe, and a second one-way valve is provided in the liquid outlet. A piston plate is slidably embedded in the box body, and the top of the piston plate is fixedly connected to the piston rod, and the top of the piston rod extends out of the box body and is connected to a push plate; when the limit plate rotates, the push plate is driven up and down by the linkage device.

[0007] In this technical solution, it should be noted that the box body serves as the main structure of the liquid outlet device, provides installation space for internal components, is made of high-strength engineering plastics with a wall thickness of 2mm, ensuring that it is not easily deformed under pressure; the liquid inlet realizes the connection between the liquid tank and the box body, so that the deicing liquid in the liquid tank can enter the box body, and the first one-way valve inside it only allows the deicing liquid to flow from the liquid tank to the box body to prevent liquid backflow; the liquid outlet is used to transport the deicing liquid in the box body to the liquid outlet pipe, and the second one-way valve inside it only allows the deicing liquid to flow from the box body to the liquid outlet pipe to prevent the deicing liquid from flowing back into the box body; the piston plate fits tightly against the inner wall of the box body and can slide up and down in the box body, realizing the suction and discharge of liquid by changing the volume of the internal space of the box body. It is made of rubber and has good sealing performance; the piston rod connects the piston plate and the push plate, plays a role in force transmission, and is made of stainless steel to ensure sufficient strength; the push plate serves 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 up and down. When the push plate moves downward, the piston rod pushes the piston plate downward within the box, reducing the volume of the space inside the box and increasing the pressure, causing the de-icing liquid to push open the second one-way valve and enter the liquid outlet pipe from the liquid outlet. When the push plate moves upward, the piston plate also slides upward, forming a negative pressure in the box, pushing open the first one-way valve, and the de-icing liquid in the liquid tank enters the box through the liquid inlet. This reciprocating process achieves continuous output of de-icing liquid. By providing a liquid outlet device consisting of the box, 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 liquid is achieved, ensuring 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. Preferably, the linkage device includes a cam, which is arranged on the side wall of the limit plate, and the end of the cam is in contact with the top of the push plate. A spring is sleeved on the piston rod, one end of the spring is connected to the push plate, and the other end is connected to the top of the box body.

[0008] In this technical solution, it should be noted that the cam is fixed to the side wall of the limit plate and rotates synchronously with the limit plate. Its irregular profile creates a periodic squeezing effect on the push plate during rotation. A spring is mounted on the piston rod, one end connected to the bottom of the push plate and the other end fixed to the top of the box. Its elastic deformation provides a reset force. When the limit plate rotates, the cam rotates with it. The cam's raised portion contacts the top of the push plate and presses it downward, driving the piston rod and piston plate downward. At this time, the spring is compressed and accumulates force, and the deicing fluid in the box is discharged through the liquid outlet under the pressure of the piston plate. When the cam's raised portion rotates away from the push plate, the elastic force of the spring pushes the push plate upward, causing the piston rod and piston plate to reset, creating negative pressure in the box, and the deicing fluid in the liquid tank enters the box through the liquid inlet. Through the cooperation of the cam and spring, the continuous rotation of the limit plate is converted into the reciprocating up and down motion of the push plate, thereby driving the liquid discharge device to operate continuously.

[0009] Preferably, there are multiple cams, and the multiple cams are arranged at equal intervals along the circumference of the limiting plate.

[0010] In this technical solution, it should be noted that multiple equidistantly spaced cams cooperate with springs to make the reciprocating motion of the push plate more continuous, and the number of pushes on the piston plate per unit time is increased, thereby increasing the output frequency of the de-icing liquid and making the liquid output more stable. The ice layer on the wire can be cleared more efficiently, further enhancing the operating performance of the device in an icing environment.

[0011] Preferably, the bottom of the U-shaped structure of the hanger is rotatably connected to an arc frame, and the arc frame is located below the U-shaped structure; a first tension spring is provided on the hanger, one end of the first tension spring is connected to the arc frame, and the other end is connected to the hanger.

[0012] In this technical solution, it should be noted that in the initial state, the arc frame is located below the U-shaped structure under the tension of the first tension spring. When the drone lifts the hanger to the position of the wire and releases it, the arc frame first contacts the wire. Due to the gravity of the entire device, the hanger moves downward relative to the wire. The arc frame begins to rotate around the rotation point due to the resistance of the wire. The first tension spring is stretched and stored. As the arc frame continues to rotate, its other end gradually rotates downward, and finally the lower opening of the U-shaped structure is closed by the rotated arc frame. Through the cooperation of the arc frame and the first tension spring, the opening can be automatically closed after the hanger is stuck in the wire, effectively preventing the device from falling off from the U-shaped structure due to vibration or wire shaking during operation, further improving the stability and reliability of the connection between the device and the wire, and ensuring the smooth progress of the grounding operation.

[0013] Preferably, a support frame is provided on the top of the hanger, a slider is provided on the support frame, and a slide groove is provided on the hanger, the slide groove is vertically arranged, the slider is slidably embedded in the slide groove, a lifting ring is provided on the side wall of the support frame, and a control box is provided on the top of the support frame; the inner side of the hanger is rotatably connected to the splints through the hinge shaft, the two splints are symmetrical and inclined, and the opposite ends of the two splints are respectively provided with arc grooves; the two hinge shafts are respectively fixed with rotating plates, the two rotating plates are inclined and symmetrical to each other, and the two rotating plates are located below the support frame, and the outer side of the hanger is provided with fixed pulleys 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, and the pull rope passes around the corresponding fixed pulley and is connected to the slider.

[0014] 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 the lifting ring. The support frame is provided with a slider made of wear-resistant cast iron, and the hanger is provided with a slide groove. The slide groove is set vertically, and the groove width is adapted to the slider. The slider is slidably embedded in the slide groove, allowing the support frame to slide stably vertically along the hanger. The lifting ring is made of 40Cr alloy steel for connection to the drone. The control box is made of ABS engineering plastic and has an integrated control element for coordinating the movements of various components. The splint is made of high-strength manganese steel with an anti-corrosion surface treatment. The arc groove is provided with anti-slip grooves to increase friction with the wire. The rotating plate is made of Q235 steel plate. When the drone lifts the hanger through the lifting ring, the support frame is in a high position under the action of the lifting rope tension; when the drone releases the hanger, the control box drives the support frame and the slider to move downward along the slide groove due to gravity, and the slider pulls the pull rope to move downward synchronously, forcing the rotating plate to rotate around the hinge axis, and the rotating plate drives the hinge axis to rotate synchronously, thereby causing the two clamps to rotate in opposite directions, and the arc groove gradually fits the wire and clamps it. Preferably, the rotating plate is connected to the hanger via a second tension spring.

[0015] In this technical solution, it should be noted that the cooperation between the second tension spring and the rotating plate can assist the rotating plate and the clamping plate to quickly reset after the operation is completed, thereby improving the reuse efficiency of the device and further optimizing the rationality and practicality of the overall structure.

[0016] Preferably, the limit plate is connected to the roller through a bearing, the limit plate is fixedly sleeved on the side wall of the bearing, and the bearing is rotatably sleeved on the side wall of the roller. It also includes a one-way rotation component that cooperates with the roller and the bearing. When the control rope is pulled to make the roller rotate in the forward direction, the roller drives the limit plate to rotate through the one-way rotation component. When the roller rotates in the reverse direction, the limit plate does not rotate due to the action of the one-way rotation component.

[0017] In this technical solution, it should be noted that when the control rope is pulled to cause the roller to rotate in the forward direction, the limit plate is driven to rotate through the bearing under the action of the one-way rotation component; when the roller rotates in the reverse direction, the limit plate will not rotate with the roller under the action of the one-way rotation component. When the hanger needs to be removed, the staff loosens the control rope, and the roller rotates in the reverse direction under the action of the gravity of the terminal block, etc. At this time, due to the action of the one-way rotation component, the limit plate will not rotate, and the cam and the push plate will not interact, the liquid outlet device will stop working, and no de-icing liquid will be sprayed. Through this setting, a one-way controllable output of the de-icing liquid is achieved. When the grounding device is hung, the de-icing liquid can be sprayed normally to remove the ice layer, ensuring that the device is stable and fixed. The spraying is stopped when the device is removed, avoiding unnecessary consumption of the de-icing liquid. At the same time, it also prevents interference with the operation caused by the spraying during the removal process, thereby improving the practicality and economy of the device.

[0018] Preferably, the one-way rotation assembly includes a ratchet and a pawl, the ratchet is fixedly sleeved on the side wall of the bearing, the pawl is fixed on the roller through a first bracket, and the pawl cooperates with the ratchet.

[0019] In this technical solution, it should be noted that the ratchet is made of 45# steel, which has a high hardness after quenching. It is fixedly mounted on the side wall of the bearing, and its teeth are evenly distributed around the circumference, making it easy to cooperate with the pawl. The pawl is made of spring steel, which has good elasticity and wear resistance. It is fixed to the roller via 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 via a pin. The pawl and ratchet cooperate with each other, and the end of the pawl contacts the teeth of the ratchet. When the control rope is pulled to rotate the roller in the forward direction, the roller drives the first bracket and the pawl to rotate synchronously. The pawl engages the gap between the ratchet teeth, pushing the ratchet to rotate with the roller, and then driving the limit plate 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 uses the one-way transmission characteristics of the ratchet and pawl to accurately achieve the goal of driving the limit plate to rotate to trigger de-icing when the roller rotates in the forward direction, and the limit plate stops to stop de-icing when it rotates in the reverse direction. It further optimizes the reliability of the one-way transmission, ensures that the de-icing fluid is accurately sprayed when hanging and completely shut down when removing, reduces the waste of de-icing fluid, and improves the working stability of the device.

[0020] Preferably, a second bracket is fixed on the rotating roller, and an elastic pressing piece is provided at the end of the second bracket, and the bottom of the elastic pressing piece is in contact with the top of the pawl.

[0021] In this technical solution, it should be noted that the elastic pressure plate continuously presses the pawl under the action of 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 cooperation stability between the pawl and the ratchet is further enhanced, the failure risk during one-way transmission is reduced, the service life of the components is extended, and at the same time the accuracy of the de-icing fluid injection control is ensured, so that the device maintains reliable performance during repeated hanging and disassembly operations. In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the coordination of the liquid tank, liquid outlet device, nozzle, and linkage device enables simultaneous de-icing of the wires during the raising and lowering of the terminal block, solving the problem of unstable fixation and slippage of the device caused by icing of the wires, and improving the reliability and efficiency of drone-assisted grounding operations. 2. The present invention utilizes a liquid discharge device consisting of a housing, piston plate, piston rod, push plate, and one-way valve, combined with a linkage and limit plate, to achieve quantitative and stable output of deicing fluid, ensuring continuous deicing of wires during the raising and lowering of the terminal block, further enhancing the reliability of the device in icing environments. 3. In the present invention, the automatic clamping of the wire is achieved through the cooperation of the support frame, slider, chute, clamping plate, rotating plate and pull rope, further enhancing the connection strength between the device and the wire; 4. In the present invention, the one-way rotating assembly is provided to achieve unidirectional controllable output of the de-icing liquid. When the grounding device is hung, the de-icing liquid can be sprayed normally to remove the ice layer, ensuring that the device is stably fixed. When the device is removed, the spraying is stopped, thereby avoiding unnecessary consumption of the de-icing liquid. At the same time, it also prevents interference with the operation caused by the spraying during the removal process, thereby improving the practicality and economy of the device.

[0029] Example 1.

[0030] like Figures 1-9 As shown, an embodiment of the present invention discloses a wire grounding device for assisting the hanging and removing of a drone, comprising a hanger 1, one end of the top of the hanger 1 being a U-shaped structure 3, a roller 13 being rotatably connected to the inner side of the hanger 1, and two limit plates 14 being sleeved on the roller 13, and the two limit plates 14 being spaced apart; It also includes a control rope 6, one end of which is connected to a wiring seat 5, the other end of which is passed around a roller 13, and the control rope 6 is located between two limit plates 14, and a ground wire is provided at the bottom of the wiring seat 5; A liquid tank 15 is further provided on the inner side of the hanger 1. A liquid outlet device is provided on one side of the liquid tank 15. A liquid outlet pipe 17 is connected to the liquid outlet device. The liquid outlet end of the liquid outlet pipe extends above the hanger 1 and is connected to a nozzle 171. The liquid spray port of the nozzle 171 faces downward. It also includes a linkage device, which drives and connects the limit plate 14 and the liquid discharge device. When the limit plate 14 rotates, the liquid discharge device is started through the linkage device.

[0031] It should be noted that the hanger 1 serves as the bearing frame of the entire device, and the U-shaped structure at one end of its top is used to clamp the device on the conductor 2 to provide stable support for the device. It is made of high-strength aluminum alloy; the limit plate 14 is mounted on the roller 13 and is arranged at intervals to limit the position of the control rope 6 on the roller 13 to prevent it from deviating. It has a diameter of 9 cm and is made of plastic, which is light and has a certain 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 conductive properties to ensure reliable grounding; the liquid tank 15 is used to store deicing liquid, has a capacity of 600 ml, and is made of lightweight polyethylene plastic to reduce the overall weight of the device; the liquid outlet device can control the output of the deicing liquid, and the liquid outlet pipe 17 is a low-temperature resistant hose. The nozzle 171 is set downward to spray the deicing liquid accurately on the surface of the conductor 2 to break the ice layer; the linkage device is responsible for converting the rotation of the limit plate 14 into the start-up of the liquid outlet device, so as to achieve synchronization between deicing and the lifting and lowering of the terminal block 5. The overall working principle is as follows: the drone lifts the hanger 1 to the designated position of the conductor 2 and then releases it. The hanger 1 is locked on the conductor 2 through the U-shaped structure; the ground staff pulls the control rope 6, which drives the roller 13 to rotate. The rotation of the roller 13 causes the terminal block 5 to move upward. At the same time, the roller 13 drives the limit plate 14 to rotate. The limit plate 14 triggers the liquid discharge device to start through the linkage device. The deicing liquid is sprayed from the nozzle 171 through the liquid discharge pipe 17 onto the conductor 2. When the terminal block 5 is raised to the highest position and grounded, the staff fixes the control rope 6 to the ground. By setting up the U-shaped structure, the roller 13, and the limit plate 14, the stable coordination between the device and the conductor 2 and the orderly pulling of the control rope 6 are guaranteed; through the coordination of the liquid tank 15, the liquid discharge device, the nozzle 171 and the linkage device, the conductor 2 is de-iced synchronously when the terminal block 5 is raised or lowered, solving the problem of unstable fixation and easy slipping of the device caused by the ice on the conductor 2, and improving the reliability and efficiency of the drone-assisted hanging and disassembly grounding operation.

[0032] Example 2.

[0033] like Figure 7-Figure 9As shown, this embodiment is roughly the same as the above embodiment, except that the liquid outlet device includes a box body 16, which is located on one side of the liquid tank 15, and a liquid inlet connected to the liquid tank 15 is penetrated on the box body 16, and a first one-way valve 151 is provided in the liquid inlet, and a liquid outlet connected to the liquid outlet pipe 17 is also penetrated on the box body 16, and a second one-way valve 161 is provided in the liquid outlet, and a piston plate 162 is slidably embedded in the box body 16, and the top of the piston plate 162 is fixedly connected to the piston rod 163, and the top of the piston rod 163 passes through the outside of the box body 16 and is connected to the push plate 164; when the limit plate 14 rotates, the push plate 164 is driven up and down by the linkage device. It should be noted that the box body 16 serves as the main structure of the liquid outlet device, provides installation space for internal components, is made of high-strength engineering plastic, and has a wall thickness of 2mm to ensure that it is not easily deformed under pressure; the liquid inlet realizes the communication between the liquid tank 15 and the box body 16, so that the deicing liquid in the liquid tank 15 can enter the box body 16, and the first one-way valve 151 inside it only allows the deicing liquid to flow from the liquid tank 15 to the box body 16 to prevent the liquid from flowing back; the liquid outlet is used to transport the deicing liquid in the box body 16 to the liquid outlet pipe 17, and the second one-way valve 161 inside it only allows the deicing liquid to flow from the box body 16 to the liquid outlet pipe 17. The liquid flows from the box 16 to the liquid outlet pipe 17 to prevent the deicing liquid from flowing back into the box 16; the piston plate 162 fits tightly against the inner wall of the box 16 and can slide up and down in the box 16 to achieve the suction and discharge of liquid by changing the volume of the internal space of the box 16. It is made of rubber and has good sealing performance; the piston rod 163 connects the piston plate 162 and the push plate 164 to transmit force and is made of stainless steel to ensure sufficient strength; the push plate 164 serves as 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, the piston plate 162 is pushed downward in the box body 16 by the piston rod 163, the volume of the space in the box body 16 decreases, the pressure increases, and the de-icing liquid pushes the second one-way valve 161 to open and enter the liquid outlet pipe 17 from the liquid outlet. When the push plate 164 moves upward, the piston plate 162 slides upward accordingly, forming a negative pressure in the box body 16, the first one-way valve 151 is pushed open, and the de-icing liquid in the liquid tank 15 enters the box body 16 through the liquid inlet. This reciprocating process achieves continuous output of the de-icing liquid. By providing a liquid outlet device consisting of the box body 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 the de-icing liquid is achieved, ensuring that the wires 2 are continuously de-iced during the lifting and lowering of the terminal block 5, further improving the reliability of the device in icing environments.

[0034] like Figure 7-Figure 9As shown, in this embodiment, the linkage device includes a cam 147, which is mounted on the side wall of the limit plate 14. The end of the cam 147 contacts the top of the push plate 164. The piston rod is provided with a spring 165, one end of which is connected to the push plate 164 and the other end is connected to the top of the box body 16. It should be noted that the cam 147 is fixed to the side wall of the limit plate 14 and rotates synchronously with the limit plate 14. Its irregular profile can form a periodic squeezing effect on the push plate 164 during the rotation process; the spring 165 is mounted on the piston rod 163, one end of which is connected to the bottom of the push plate 164 and the other end is fixed to the top of the box body 16, and uses its own elastic deformation to provide a reset force. When the limit plate 14 rotates, the cam 147 rotates with the limit plate 14. The raised portion 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 the piston plate 162 downward. At this time, the spring 165 is compressed and stored. Under the pressure of the piston plate 162, the deicing liquid in the tank 16 is discharged through the liquid outlet. When the raised portion of the cam 147 rotates away from the push plate 164, the elastic force of the spring 165 pushes the push plate 164 upward. The piston rod 163 and the piston plate 162 are then reset. Negative pressure is formed in the tank 16, and the deicing liquid in the liquid tank 15 enters the tank 16 through the liquid inlet. Through the cooperation of the cam 147 and the spring 165, the continuous rotation of the limit plate 14 is converted into the reciprocating upward and downward motion of the push plate 164, thereby driving the liquid discharge device to continue to operate.

[0035] like Figure 8 As shown, in this embodiment, multiple cams 147 are provided, and the multiple cams 147 are evenly spaced along the circumference of the limit plate 14. It should be noted that the multiple evenly spaced cams 147 cooperate with the spring 165 to make the reciprocating motion of the push plate 164 more consistent, increasing the number of pushes on the piston plate 162 per unit time, thereby increasing the output frequency of the deicing fluid and making the output more stable. This allows for more efficient removal of ice from the conductor 2, further enhancing the device's operational performance in icing environments.

[0036] Example 3.

[0037] like Figure 1-Figure 5As shown, this embodiment is substantially the same as the above embodiment, except that the bottom of the U-shaped structure 3 of the hanger 1 is rotatably connected to an arc frame 4, and the arc frame 4 is located below the U-shaped structure 3; the hanger 1 is provided with a first tension spring 23, one end of the first tension spring 23 is connected to the arc frame 4, and the other end is connected to the hanger 1. It should be noted that in the initial state, the arc 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 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. The arc frame 4 is subjected to the resistance force of the wire 2 and begins to rotate around the rotation point. The first tension spring 23 is stretched and stored. As the arc frame 4 continues to rotate, its other end gradually rotates downward, and finally the lower opening of the U-shaped structure is closed by the rotated arc frame 4. Through the cooperation of the arc frame 4 and the first tension spring 23, the opening can be automatically closed after the hanger 1 is clamped into the conductor 2, effectively preventing the device from falling off from the U-shaped structure due to vibration or shaking of the conductor 2 during operation, further improving the stability and reliability of the connection between the device and the conductor 2, and ensuring the smooth progress of the grounding operation.

[0038] like Figure 6As shown, in this embodiment, the top of the hanger 1 is provided with a support frame 8, a slider 18 is provided on the support frame 8, and a slide groove 19 is provided on the hanger 1. The slide groove 19 is vertically arranged, and the slider 18 is slidably embedded in the slide groove 19. A lifting ring 9 is provided on the side wall of the support frame 8, and a control box 7 is provided on the top of the support frame 8; the inner side of the hanger 1 is rotatably connected with a splint 10 through a hinge shaft 21, and the two splints 10 are symmetrical and tilted. The opposite ends of the two splints 10 are respectively provided with an arc groove 12; a rotating plate 20 is fixedly sleeved on the two hinge shafts 21, and the two rotating plates 20 are tilted and symmetrical to each other, and the two rotating plates 20 are located below the support frame 8, and the outer side of the hanger 1 is provided with a fixed pulley 25 corresponding to the number of rotating plates 20, each of the fixed pulleys 25 is located above the corresponding rotating plate 20, and each of the rotating plates 20 is provided with a pull rope 24, and the pull rope 24 passes around the corresponding fixed pulley 25 and is connected 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 hanging ring 9; the support frame 8 is provided with a slider 18, which is made of wear-resistant cast iron, and the hanger 1 is provided with a slide 19, which is vertically arranged, and the groove width is adapted to the slider 18. The slider 18 is slidably embedded in the slide 19, so that the support frame 8 can slide vertically along the hanger 1 stably; the hanging ring 9 is made of 40Cr alloy steel for connection with the drone; the control box 7 is made of ABS engineering plastic, with an internal integrated control element for coordinating the actions of various components. The splint 10 is made of high-strength manganese steel with an anti-corrosion surface treatment, and the arc groove 12 is provided with anti-slip grooves to increase the friction with the wire 2; the rotating plate 20 is made of Q235 steel plate. When the drone lifts the hanger 1 through the lifting ring 9, the support frame 8 is in a high position under the action of the tension of the lifting rope; when the drone releases the hanger 1, the control box 7 drives the support frame 8 and the slider 18 to move downward along the slide groove 19 due to the action of gravity, and the slider 18 pulls the pull rope 24 to move downward synchronously, forcing the rotating plate 20 to rotate around the hinge shaft 21, and the rotating plate 20 drives the hinge shaft 21 to rotate synchronously, thereby causing the two clamping plates 10 to rotate in relative directions, and the arc groove 12 gradually fits the wire 2 and clamps it.

[0039] 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 assists in quickly resetting the rotating plate 20 and the clamping plate 10 after the operation is completed, thereby improving the reuse efficiency of the device and further optimizing the rationality and practicality of the overall structure.

[0040] Example 4.

[0041] like Figure 7-Figure 9As shown, this embodiment is substantially the same as the above-described embodiment, except that the limit plate 14 is connected to the roller 13 via a bearing 141. The limit plate 14 is fixedly mounted on the side wall of the bearing 141, and the bearing 141 is rotatably mounted on the side wall of the roller 13. The embodiment also includes a one-way rotation assembly that cooperates with the roller 13 and the bearing 141. When the control rope 6 is pulled to rotate the roller 13 in the forward direction, the roller 13 drives the limit plate 14 to rotate via the one-way rotation assembly. When the roller 13 rotates in the reverse direction, the one-way rotation assembly prevents the limit plate 14 from rotating. It should be noted that when the control rope 6 is pulled to rotate the roller 13 in the forward direction, the one-way rotation assembly drives the limit plate 14 to rotate via the bearing 141. When the roller 13 rotates in the reverse direction, the one-way rotation assembly prevents the limit plate 14 from rotating with the roller 13. When the hanger 1 needs to be removed, the worker loosens the control rope 6, and the roller 13 rotates in the opposite direction under the action of the gravity of the terminal block 5. At this time, due to the action of the one-way rotating component, the limit plate 14 will not rotate, and the cam 147 and the push plate 164 will not interact with each other, the liquid outlet device will stop working, and no de-icing liquid will be sprayed. Through this arrangement, a one-way controllable output of the de-icing liquid is achieved. When the grounding device is hung, the de-icing liquid can be sprayed normally to remove the ice layer, ensuring that the device is stable and fixed. When the device is removed, the spraying is stopped, avoiding unnecessary consumption of the de-icing liquid. At the same time, it also prevents possible interference with the operation caused by the spraying during the removal process, thereby improving the practicality and economy of the device.

[0042] like Figure 8As shown, in this embodiment, the one-way rotation assembly includes a ratchet 142 and a pawl 143. The ratchet 142 is fixedly mounted on the side wall of the bearing 141, and the pawl 143 is fixed to the roller 13 via a first bracket 144. The pawl 143 and the ratchet 142 cooperate with each other. It should be noted that the ratchet 142 is made of 45 steel, which has a high hardness after quenching. It is fixedly mounted on the side wall of the bearing 141, and the teeth are evenly distributed around the circumference, which facilitates cooperation with the pawl 143. The pawl 143 is made of spring 165 steel, which has good elasticity and wear resistance. It is fixed to the roller 13 via a 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. The pawl 143 and the ratchet 142 cooperate with each other, and the end of the pawl 143 contacts the teeth of the ratchet 142. When the control rope 6 is pulled to rotate the roller 13 in the forward direction, the roller 13 drives the first bracket 144 and the pawl 143 to rotate synchronously. The pawl 143 is embedded in the gap between the teeth of the ratchet 142, pushing the ratchet 142 to rotate along with the roller 13, and then drives the limit plate 14 to rotate through the bearing 141. When the roller 13 rotates in the reverse direction, the pawl 143 is lifted by the inclined surface of the ratchet 142 teeth and disengaged from the ratchet 142 teeth. At this time, the ratchet 142, the bearing 141, and the limit plate 14 do not rotate with the roller 13. This structure, through the one-way transmission characteristics of the ratchet 142 and the pawl 143, accurately realizes that when the roller 13 rotates in the forward direction, the limit plate 14 rotates to trigger deicing, and when the roller rotates in the reverse direction, the limit plate 14 stops to stop deicing. This further optimizes the reliability of the one-way transmission, ensures that the deicing fluid is accurately sprayed when hanging and completely shut down when removing, reduces the waste of deicing fluid, and improves the working stability of the device.

[0043] like Figure 8 As shown, in this embodiment, a second bracket 146 is further fixed to the rotating roller 13. An elastic pressing piece 145 is provided at the end of the second bracket 146. The bottom of the elastic pressing piece 145 contacts the top of the pawl 143. It should be noted that the elastic pressing piece 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. The cooperation between the second bracket 146 and the elastic pressing piece 145 further enhances the coordination stability between the pawl 143 and the ratchet 142, reduces the risk of failure during one-way transmission, extends the service life of the components, and ensures the accuracy of the deicing fluid injection control, so that the device maintains reliable performance during repeated hanging and dismantling operations.

[0044] The working principle of the present invention is: During operation, the drone is connected to the support frame 8 through the lifting ring 9, and the entire device is lifted and transported to the designated position of the wire 2. At this time, the support frame 8 is in a high position under the action of the lifting rope tension, the second tension spring 22 is in a naturally extended state, the two eight-shaped rotating plates 20 maintain the initial opening angle, and the arc frame 4 is located under 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 wire 2. As the device continues to fall, the arc frame 4 rotates around the rotation point due to the resistance force of the wire 2, the first tension spring 23 is stretched, and finally the arc frame 4 closes the opening below the U-shaped structure. At the same time, the control box 7 drives the support frame 8 and the slider 18 to slide downward along the slide groove 19. The slider 18 is stably guided in the slide groove 19, and by driving the pull rope 24 to move downward, the rotating plate 20 rotates around the hinge shaft 21 and drives the clamping plate 10 to rotate. The second tension spring 22 is stretched, and the two clamping plates 10 clamp the wire 2 through the arc groove 12. Then the ground staff pulls the control rope 6. The control rope 6 drives the roller 13 to rotate forward under the limit of the two limit plates 14. The roller 13 drives the pawl 143 to rotate through the first bracket 144. The elastic pressing piece 145 presses the pawl 143 to make it tightly meshed with the ratchet 142, pushing the ratchet 1 42. The bearing 141 and the limit plate 14 rotate synchronously, and the multiple equidistant cams 147 rotate with the limit plate 14, squeezing the push plate 164 in turn. The push plate 164 drives the piston rod 163 and the piston plate 162 to move downward, and the spring 165 is compressed. The deicing liquid in the box body 16 pushes the second one-way valve 161 to be sprayed from the nozzle 171 through the liquid outlet pipe 17 to the surface of the wire 2. After the cam 147 rotates away, the spring 165 pushes the push plate 164 to return to its original position, and the piston plate 162 moves upward to form a negative pressure in the box body 16. The first one-way valve 151 is opened, and the deicing liquid in the liquid tank 15 is replenished to the box body 16 through the liquid inlet. This reciprocating process realizes continuous deicing. As the control rope 6 is pulled , the terminal block 5 gradually rises to contact with the wire 2, completing the grounding, and the staff fixes the control rope 6; after the operation is completed, the drone lifts the device again, the support frame 8 moves up, the second tension spring 22 pulls the rotating plate 20 and the clamping plate 10 to reset, the staff loosens the control rope 6, and the gravity of the terminal block 5 drives the roller 13 to rotate in the opposite direction. At this time, the pawl 143 is lifted up under the action of the inclined surface of the ratchet teeth 142 and disengaged from the ratchet 142. The limit plate 14 stops rotating, the cam 147 no longer squeezes the push plate 164, the liquid outlet device stops spraying liquid, and at the same time, the arc frame 4 is reset under the action of the first tension spring 23 to open the U-shaped structure opening, and the device is separated from the wire 2 to complete the dismantling.
