Description

Technical Field

[0001] This invention belongs to the technical field of grounding wire facilities, specifically relating to a grounding wire device that requires no climbing. Background Technology

[0002] In today's era, with the rapid development of science and technology and the continuous advancement of modernization, electricity has become the cornerstone supporting the operation of society. Society's expectations for the reliability of power supply have also risen steadily, reaching an unprecedented level. The stable supply of electricity is of irreplaceable importance to all aspects, such as ensuring the normal life of residents, promoting the continuous operation of industrial production, and maintaining the orderly conduct of commercial activities. At the same time, the requirements for the economic benefits of power grid companies have become increasingly stringent and refined.

[0003] In the field of power system operation and maintenance, switching operations are one of the key operational processes to ensure the safe and stable operation of the power grid. The connection and removal of grounding wires is an indispensable and important part of switching operations. The standardization and accuracy of the operation will have a significant impact on the overall operational safety and work efficiency of the switching operations. In actual power grid operation and maintenance scenarios, the connection and removal of grounding wires currently require operation and maintenance personnel to work at height.

[0004] In existing technologies, traditional power outage and restoration operations have significant shortcomings in the high-altitude work process. The operation is complex, involving multiple steps such as moving and climbing ladders, arranging cranes, and setting up ladders or outriggers. It requires the cooperation of multiple people and demands a high degree of teamwork. From a safety perspective, during high-altitude operations, maintenance personnel face a serious risk of falling from heights. In the event of an accident, not only will the lives of maintenance personnel be threatened, but it may also cause a power outage and affect the reliability of power supply. From an efficiency perspective, the cumbersome process directly leads to excessively long operation times. Each step, such as moving and climbing ladders, arranging cranes, and setting up ladders or outriggers, requires a significant amount of time and manpower. Moreover, since grounding wires are usually quite heavy, it is difficult for a single person to complete the connection or removal operation, which further increases the difficulty and time cost of the operation. In the context of the rapid development of the power industry, this inefficient and high-risk operation method can no longer meet the needs of modern society for efficient and safe work sites. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a grounding wire device that eliminates the need for personnel to climb to heights to complete the connection and removal of grounding wires.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grounding wire connection device that eliminates the need for climbing. This grounding wire connection device aims to safely and quickly complete the connection and removal of grounding wires at pre-set work points on high-voltage towers without requiring climbing. The device includes a hanging head, a connection / removal contact device, a power device, a sealing device, a drive device, a limiting device, and a grounding wire device. The bottom of the hanging head is fixedly connected to an insulating rod. The connection / removal contact device is slidably connected to the surface of the insulating rod by means of power provided by the power device. The upper end of the power device is fixed to a sealing plate by the sealing device. The connection / removal contact device is fixed to the grounding wire by the grounding wire device.

[0007] The hanging head is used to precisely hang the device at the preset working point on the high-voltage tower. The hanging and removing contact device is used for the quick hanging and removing of the grounding wire. The power unit is responsible for moving the hanging and removing contact device along the insulating rod to the top of the insulating rod to perform the grounding wire hanging and removing operation. The sealing device is used to provide sealed protection for the power unit. The limiting device is used to fix the drive unit inside the power unit. The drive unit is used to provide a power source for the power unit. The grounding wire device is used to ensure a reliable electrical connection between the grounding wire and the hanging and removing contact device.

[0008] A mounting rod is fixed to the bottom of the hanging head. The surface of the mounting rod is slidably connected to the hanging / removing contact device. The hanging / removing contact device includes at least a sliding collar. A fixed housing is fixed to the circumference of the sliding collar. A guide ring is fixed to the upper end of the fixed housing. A mounting wing hook is rotatably connected to the circumference of the guide ring. A hook is fixed to the front end of the mounting wing hook. The hook is closed or open under the action of the power device. In the closed state, the hook is engaged with the mounting rod. In the open state, it is disengaged from the mounting rod. A limit plate is rotatably connected to the inner wall of the fixed housing. A cylindrical sliding pin is fixed to the bottom of the limit plate. A pressure spring is fixed to the bottom of the sliding collar. The sliding collar slides internally. A sliding block is connected, and a groove is opened on the surface of the sliding block. A bearing plate is fixed on the periphery of the sliding block. The bearing plate is slidably connected to the periphery of the fixed sleeve. An abutment ring is fixed on the surface of the bearing plate. The grounding wire forms a passage with the guide ring, the hanging rod, and the hanging head. A limit strip is fixed on the inner wall of the fixed sleeve. The limit strip is slidably connected to the periphery of the sliding block. An insulating rod is fixed at the bottom of the hanging rod. The power device includes at least a power housing. A rubber wheel is rotatably connected to the inner wall of the power housing. The rubber wheel is driven to rotate by a drive device. The surface of the rubber wheel is in contact with the insulating rod. The drive device drives the rubber wheel to move along the surface of the insulating rod.

[0009] In existing technologies, traditional power outage and restoration operations have significant shortcomings in the high-altitude work process. The operation is complex, involving multiple steps such as moving and climbing ladders, arranging cranes, and setting up ladders or outriggers. It requires the cooperation of multiple people and demands a high degree of teamwork. From a safety perspective, during high-altitude operations, maintenance personnel face a serious risk of falling from heights. In the event of an accident, not only will the lives of maintenance personnel be threatened, but it may also cause power outages and affect the reliability of power supply. From an efficiency perspective, the cumbersome process directly leads to excessively long operation time. Each step, such as moving and climbing ladders, arranging cranes, and setting up ladders or outriggers, requires a lot of time and manpower. Moreover, since grounding wires are usually quite heavy, it is difficult for a single person to complete the connection or removal operation, which further increases the difficulty and time cost of the operation. In the context of the rapid development of the power industry, this inefficient and high-risk operation method can no longer meet the needs of modern society for efficient and safe work sites.

[0010] In this invention, when maintenance personnel need to use this device for non-vertical hanging and dismantling operations, they connect and fix the mounting pole and insulating pole to the hanging head. Then, using the insulating pole, they hang the hanging head at the pre-set work point on the high-voltage tower. Next, they install and fix the grounding wire and the hanging / dismantling contact device. Finally, they install the hanging / dismantling contact device and the power unit at the bottom of the insulating pole. The maintenance personnel can then wirelessly remotely control the drive device to move the power unit along the insulating pole towards the mounting pole. As the power unit rises, the hanging / dismantling contact device moves along the insulating pole towards the mounting pole. When the power unit pushes the hanging / dismantling contact device to the top of the mounting pole, it continues to climb, pushing the abutment ring. As the slide block rises, it compresses the pressure spring and slides to the top. After the slide block moves, the cylindrical pin at the front end of the limit plate slides to the bottom of the slot. Then, the maintenance personnel use wireless remote control to drive the power unit to move along the insulating rod to the bottom. At this time, the pressure spring pushes the slide block to move along the mounting rod until the bottom of the slot abuts against the cylindrical pin, causing the abutment ring to be unable to move and squeezing the tail of the mounting wing hook, causing it to close and engage with the mounting rod. At this point, a path is formed between the mounting head, mounting rod, hook, guide ring and grounding wire. Then, the maintenance personnel use wireless remote control to move the power unit along the insulating rod to the bottom for disassembly. At this time, the maintenance personnel have completed the grounding wire connection work at the preset work point of the high-voltage tower. In addition, if maintenance personnel need to remove the grounding wire at the pre-set work point of the high-voltage tower, they can use a wireless remote control to control the power unit to climb along the pre-reserved insulating rod at the pre-set work point of the high-voltage tower until the power unit moves to the mounting rod. Then, the power unit continues to climb, pushing the abutment ring to move the sliding block to the top, causing the cylindrical sliding pin to disengage from the tip of the groove. Then, the maintenance personnel can use a wireless remote control to lower the power unit along the insulating rod. At this time, the pressure spring pushes the sliding block to reset, the cylindrical sliding pin moves to the top of the groove, the abutment ring resets, the mounting wing hook opens and disengages from the mounting rod, and then the dismantling contact device descends with the power unit until it reaches the bottom of the insulating rod for dismantling by the maintenance personnel. In this way, the maintenance personnel complete the removal of the grounding wire at the pre-set work point of the high-voltage tower.

[0011] Furthermore, the sealing device includes a sealing shell, which is fixedly connected to the interior of the sealing plate. A circular ring is fixed inside the sealing shell, and a sliding pin is slidably connected inside the sealing shell. An arc-shaped groove is formed on the circumference of the sliding pin, and a compression spring is fixedly fixed on the surface of the sliding pin. The upper end of the compression spring is fixedly connected to the bottom of the circular ring. A sealing bead is slidably connected inside the sealing shell, and the surface of the sealing bead is slidably connected to the surface of the arc-shaped groove. A pressing cap is slidably connected to the upper end of the sealing shell, and a return spring is fixedly fixed inside the pressing cap. The bottom of the return spring is fixedly connected to the upper end of the sliding pin. A locking bead is slidably connected inside the sealing shell, and a fixing pin is sleeved on the bottom of the sealing shell. An arc-shaped groove is formed on the surface of the fixing pin, and the bottom of the fixing pin is fixedly connected to the surface of the power housing.

[0012] In this invention, when a worker replaces a damaged unit, the worker presses the pressing cap. The downward pressure of the pressing cap is transmitted to the sealing bead, causing the sealing bead to press against the sliding pin with the help of the ring. This causes the sliding pin to move upward against the spring force, allowing the locking bead at the bottom of the sealed housing to disengage from the fixing pin. At this point, the worker can separate the sealing plate from the power housing and replace the internal unit of the power device. After replacement, the worker resets the sealing plate. After resetting the sealing plate, the worker releases the pressing handle, and the reset spring pushes the sliding pin downward. The locking bead returns to its arc groove under the pressure of the sliding pin. At the same time, the sealing ball pops out and moves to the outer end of the arc groove, completing the sealing and locking. This invention avoids the problem of difficult repair and replacement caused by integrated design, reduces parts waste, and optimizes the convenience and efficiency of repair and replacement.

[0013] Furthermore, the limiting device includes a limiting rotary cylinder, the circumference of which is fixedly connected to the inside of the power housing. A rotary knob is rotatably connected inside the limiting rotary cylinder. A coupling pin is fixed to the bottom of the rotary knob. A rotating pressure plate is fixed to the upper circumference of the coupling pin. An auxiliary spring is rotatably connected inside the limiting rotary cylinder. A pushing block is fixed to the upper end of the auxiliary spring. A pressing pin is fixed to the inner wall of the pushing block. The rotating pressure plate is slidably connected to the surface of the pressing pin. A pushing pin is fixed to the upper end of the pushing block. A circular through groove is formed on the surface of the bearing circular plate.

[0014] In this invention, when the operator needs to further replace the drive unit, the sealing plate is first separated from the power housing. Then, the rotating knob on the surface of the power housing is rotated. Rotating the knob drives the linkage pin to rotate, which in turn drives the pressing pin to move inward, pushing the propulsion pin to retract inward. This separates the bearing plate inside the power housing from the propulsion pin, allowing the bearing plate to be disassembled. After replacing the drive unit, the bearing plate is reset. Rotating the rotating knob again causes the pressing pin to disengage from the coupling pin, and the return spring quickly pushes the propulsion pin to reset, thus fixing the bearing plate. This reduces the maintenance time of the power unit, avoids the time-consuming problem of disassembling screws using traditional bolts, saves the operator time for switching operations, and further optimizes the convenience and efficiency of maintenance and replacement.

[0015] Furthermore, in the grounding wire device, a rotating knob is fixed at the front end of the grounding wire, a locking pin base is threaded onto the surface of the rotating knob, a contact connector is fixed at the bottom of the locking pin base, a through groove is opened on the circumferential surface of the locking pin base, a sliding pin is slidably connected inside the through groove, an inclined groove is opened at the front end of the sliding pin, a truncated cone is fixed at the front end of the rotating knob, the surface of the inclined groove is slidably connected to the truncated cone, a contact head is fixed at the front end of the truncated cone, the contact head contacts the contact connector to form a passage, and a sliding circular groove is opened on the circumferential surface of the guide ring, the sliding circular groove is slidably connected to the locking pin base through a key;

[0016] In existing technologies, the connection between the traditional grounding wire and the contactor is exposed, lacking effective protective measures. This makes the connection vulnerable to external factors and highly susceptible to environmental influences. Under high temperatures, the material at the connection point may thermally expand, leading to loosening. In humid environments, moisture intrusion can cause corrosion, accelerating the oxidation process at the connection point. Furthermore, corrosive gases and dust can adhere to the connection surface, forming an insulating layer that further increases contact resistance and reduces conductivity. These factors combined make the electrical connection between the grounding wire and the contactor unstable, prone to intermittent connections. Such poor contact not only reduces the reliability of the grounding system but may also cause malfunctions during equipment operation, increasing safety risks, especially in critical electrical systems, potentially leading to serious consequences.

[0017] In this invention, the operator first precisely aligns the locking pin base with the sliding groove on the surface of the guide ring and applies appropriate force to push it into the groove. Then, by rotating a knob, it advances along a predetermined path. As the knob continues to rotate, the cone at its front end gradually engages with and presses against the sliding pin. Under the pressure of the cone, the sliding pin steadily unfolds to both sides along the circumference of the contact joint. This unfolding action is accompanied by the movement of the sliding pin towards its tail end, which in turn continuously presses against the locking pin base, causing it to move steadily forward. The forward movement of the locking pin base enhances the contact pressure between the contact joint and the guide ring, ensuring a tight and stable connection between the two. This significantly improves the reliability of the grounding wire connection and effectively prevents poor contact problems caused by environmental factors. This invention not only improves the reliability of the grounding system but also reduces the safety risks caused by poor grounding, ensuring the safety and stability of electrical equipment operation.

[0018] Furthermore, the driving device includes a bearing circular plate, a coupling housing fixed to the upper end of the bearing circular plate, a bearing rod rotatably connected inside the coupling housing, a fixing tooth fixed in the middle of the bearing rod, the bearing rod being fixedly connected to a rubber wheel through the fixing tooth, a worm gear fixed to one end of the bearing rod, a worm engaging on the surface of the worm gear, a power motor fixed inside the bearing circular plate, the driving end of the power motor being fixedly connected to the worm, and a shaft plate fixed to the upper end of the bearing circular plate, the shaft plate being rotatably connected to the bearing rod.

[0019] Furthermore, ratchet wheels are fixed at both ends of the rubber wheel, and limit teeth mesh with the surface of the ratchet wheels. A limit base is fixed at the upper end of the bearing circular plate, and the inner wall of the limit base is rotatably connected to the limit teeth. A micro motor is fixed at the upper end of the bearing circular plate, and the driving end of the micro motor is fixedly connected to the limit teeth. A fixing spring is fixed at the inner wall of the limit base.

[0020] In this invention, the self-locking property of the worm gear and the pawl swinging under the push of the ratchet teeth when the rubber wheel rotates clockwise allow the rubber wheel to rotate clockwise. At the same time, if the rubber wheel attempts to rotate counterclockwise, the pawl will engage between the ratchet teeth, preventing the rubber wheel from moving in the opposite direction. In this way, the ratchet structure can effectively prevent the rubber wheel from rotating in the opposite direction when it is not driven, ensuring that the rubber wheel can only rotate in the predetermined direction, thereby improving the stability and reliability of the device.

[0021] Furthermore, a square recess is formed on the surface of the power housing, and a rotating plate is rotatably connected inside the square recess. A handle is rotatably connected to the upper end of the rotating plate, and a tension spring is fixed inside the handle. The bottom of the tension spring is fixedly connected to the rotating plate.

[0022] In this invention, the use of tension springs can reduce component damage caused by excessive force and extend the service life of the equipment. At the same time, tension springs provide resistance to the grip, ensuring that the operator can feel clear feedback, facilitating precise control and improving user experience and equipment usability. The square recessed design houses the grip and related components inside the power housing, saving space, preventing external interference, improving safety, preventing component damage caused by rigid impacts to the grip, and extending the service life of the equipment.

[0023] Furthermore, an elastic clamp is rotatably connected to the inner wall of the hanging head, a sliding groove is provided on the inner wall of the hanging head, a support pressure strip is rotatably connected to the inner wall of the sliding groove, the side end of the support pressure strip is slidably connected to the inside of the elastic clamp, a push spring is fixed to the back of the elastic clamp, and the bottom of the push spring is fixedly connected to the inner wall of the hanging head.

[0024] In existing technologies, the stability of the mounting device on high-voltage power lines faces severe challenges under adverse weather conditions, especially windy weather. The lateral force brought by strong winds can significantly affect the mounting device, causing it to sway and swing. This swaying and swinging not only affects the normal operation of the equipment, but may also cause a series of serious safety and technical problems. The swaying of the mounting device can lead to unstable connection between it and the high-voltage power line. This instability may cause poor electrical contact, affect the normal transmission of current, and may even cause electrical faults, such as short circuits or arc discharges. These problems can not only interrupt the power supply, but may also damage the power system, increase maintenance costs and recovery time. Continuous swaying and swinging can cause mechanical stress on the mounting device and its connecting parts. Long-term mechanical stress can lead to fatigue and wear of the parts, reducing the service life of the equipment. In extreme cases, this wear may cause the parts to break or the connection to loosen, increasing the risk of the equipment falling and posing a serious threat to surrounding personnel and facilities.

[0025] In this invention, a continuous pressure is applied to the elastic clamp by a push spring, enabling the elastic clamp to tightly and securely hold the high-voltage wire. This design effectively enhances the clamping force, preventing the hanging head from swaying and swinging due to factors such as wind, ensuring the stability and safety of the equipment during operation. The constant pressure of the push spring allows the elastic clamp to adapt to the surface contour of the high-voltage wire, maintaining close contact even under windy conditions. This stable clamping method not only improves the reliability of the equipment under adverse weather conditions but also reduces electrical connection problems that may be caused by unstable hanging heads, such as poor contact or short circuits. In this way, the invention significantly improves the safety and stability of the mounted equipment in high-voltage environments, reducing maintenance costs and potential downtime.

[0026] Furthermore, a square groove is provided inside the mounting rod, a soft spring is fixed inside the square groove, and a protrusion is fixed to the side end of the soft spring. The surface of the protrusion is slidably connected to the inside of the square groove.

[0027] In this invention, after the hook-and-unhook contact device completes the hook-and-unhook operation, the soft spring applies continuous and stable pressure to the protrusion. This pressure causes the protrusion to be squeezed outward and tightly adhere to the inner wall of the hook-and-unhook contact device. This tight contact greatly increases the conductive area between the hook-and-unhook contact device and the mounting rod. A larger conductive area means more stable current flow, thus allowing the current to flow more smoothly. This enables the hook-and-unhook contact device to maintain a tight connection with the mounting rod when facing external vibration or impact, reducing the risk of poor contact caused by mechanical loosening. This mechanical stability is particularly important for equipment working in harsh environments, thereby further improving the stability of the device's conductivity.

[0028] Furthermore, the groove includes an outer tip, an inner tip, an inner tail end, an outer tail end, a first inner end, a first outer end, a first outer end, a second inner end, and a second outer end. When the device connects the grounding wire, as the power device moves along the insulating rod towards its top, the cylindrical sliding pin moves from the outer tip to the inner tip. Then, as the power device continues to push towards the top of the insulating rod, the cylindrical sliding pin moves from the inner tip along the inner side of the groove to the first inner end, then to the first outer end, until it moves along the outer side of the groove to the outer tail end. The power device then moves towards the bottom of the insulating rod. As the sliding block moves towards the bottom of the insulating rod with the help of the pressure spring, the cylindrical sliding pin moves from the outer tail end to the inner tail end. At this time, the device has completed the connection of the grounding wire. When the device removes the grounding wire, the power device moves towards the top of the insulating rod again. At this time, the cylindrical sliding pin moves from the inner tail end to the second outer end. Then, the power device moves from the top of the insulating rod to the tail end, and the cylindrical sliding pin moves along the outside of the groove from the second outer end to the outer tip to reset. At this time, the device has completed the removal of the grounding wire.

[0029] In this invention, through the unique design of the groove, when the power device pushes the abutment ring towards the top of the insulating rod, the cylindrical sliding pin moves from the outer tip to the inner tip. The power device continues to push towards the top of the insulating rod, and the cylindrical sliding pin moves along the inner side of the groove to the first inner end, then to the first outer end, until it moves along the outer side of the groove to the outer tail end. After that, the power device can descend, and at this time, the fixed pin will move from the outer tail end to the inner tail end to abut. At this time, the abutment ring will be suspended and squeezed to close the mounting hook, thus completing the grounding wire connection. When removing the grounding wire, the power device moves towards the top of the insulating rod again, and the cylindrical sliding pin moves from the inner tail end to the second outer end. Subsequently, the power device moves from the top of the insulating rod to the tail end, and the cylindrical sliding pin moves along the outer side of the groove from the second outer end to the outer tip to reset. The abutment ring can then disengage from the mounting hook, causing the mounting hook to open. The grounding wire is then removed. This achieves precise movement and positioning of the cylindrical sliding pin between different positions, ensuring efficient and stable grounding wire connection and removal operations.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In existing technologies, the traditional power outage and restoration switching operations have significant shortcomings in the high-altitude operation process. The operation is complex, involving multiple operations such as carrying and climbing ladders, arranging cranes, and setting up ladders or outriggers. It requires the cooperation of multiple people and demands a high degree of teamwork. From a safety perspective, during high-altitude operations, maintenance personnel are at a height and face a serious risk of falling from height. Once an accident occurs, it will not only threaten the lives of maintenance personnel but may also cause power outages, affecting the reliability of power supply. From the perspective of work efficiency, the cumbersome process directly leads to excessively long operation time. Each step, such as carrying and climbing ladders, arranging cranes, and setting up ladders or outriggers, requires a lot of time and manpower. Moreover, since grounding wires are usually quite heavy, it is difficult for a single person to complete the connection or removal operation, which further increases the difficulty and time cost of the operation. In the context of the rapid development of the power industry, this inefficient and high-risk operation method can no longer meet the needs of modern society for efficient and safe work sites.

[0032] In this invention, when maintenance personnel need to use this device for non-vertical hanging and dismantling operations, they connect and fix the mounting pole and insulating pole to the hanging head. Then, using the insulating pole, they hang the hanging head at the pre-set work point on the high-voltage tower. Next, they install and fix the grounding wire and the hanging / dismantling contact device. Finally, they install the hanging / dismantling contact device and the power unit at the bottom of the insulating pole. The maintenance personnel can then wirelessly remotely control the drive device to move the power unit along the insulating pole towards the mounting pole. As the power unit rises, the hanging / dismantling contact device moves along the insulating pole towards the mounting pole. When the power unit pushes the hanging / dismantling contact device to the top of the mounting pole, it continues to climb, pushing the abutment ring. As the slide block rises, it compresses the pressure spring and slides to the top. After the slide block moves, the cylindrical pin at the front end of the limit plate slides to the bottom of the slot. Then, the maintenance personnel use wireless remote control to drive the power unit to move along the insulating rod to the bottom. At this time, the pressure spring pushes the slide block to move along the mounting rod until the bottom of the slot abuts against the cylindrical pin, causing the abutment ring to be unable to move and squeezing the tail of the mounting wing hook, causing it to close and engage with the mounting rod. At this point, a path is formed between the mounting head, mounting rod, hook, guide ring and grounding wire. Then, the maintenance personnel use wireless remote control to move the power unit along the insulating rod to the bottom for disassembly. At this time, the maintenance personnel have completed the grounding wire connection work at the preset work point of the high-voltage tower. In addition, if maintenance personnel need to remove the grounding wire at the pre-set work point of the high-voltage tower, they can use a wireless remote control to control the power unit to climb along the pre-reserved insulating rod at the pre-set work point of the high-voltage tower until the power unit moves to the mounting rod. Then, the power unit continues to climb, pushing the abutment ring to move the sliding block to the top, causing the cylindrical sliding pin to disengage from the tip of the groove. Then, the maintenance personnel can use a wireless remote control to lower the power unit along the insulating rod. At this time, the pressure spring pushes the sliding block to reset, the cylindrical sliding pin moves to the top of the groove, the abutment ring resets, the mounting wing hook opens and disengages from the mounting rod, and then the dismantling contact device descends with the power unit until it reaches the bottom of the insulating rod for dismantling by the maintenance personnel. In this way, the maintenance personnel complete the removal of the grounding wire at the pre-set work point of the high-voltage tower. Attached Figure Description

When the device connects to the grounding wire 4, as the power device moves along the insulating rod 101 towards its top, the cylindrical sliding pin moves from the outer tip 2071 to the inner tip 2072. Afterward, the power device continues to move along the insulating rod 101... When the top is pushed, the cylindrical sliding pin moves from the inner tip 2072 along the inner side of the groove 207 to the first inner end 2075, then moves to the first outer end 2076, until it moves along the outer side of the groove 207 to the outer tail end 2074. Then the power device moves to the bottom of the insulating rod 101. As the sliding block 206 moves to the bottom of the insulating rod 101 with the help of the pressure spring 204, the cylindrical sliding pin moves from the outer tail end 2074 to the inner tail end 2073. At this time, the device is connected to the grounding wire 4.

[0069] When the device removes the grounding wire 4, the power device moves to the top of the insulating rod 101 again. At this time, the cylindrical sliding pin moves from the inner tail end 2073 to the second outer side end 2078. Then the power device moves from the top of the insulating rod 101 to the tail end. The cylindrical sliding pin moves along the outside of the groove 207 from the second outer side end 2078 to the outer tip 2071 to reset. At this time, the device has completed the removal of the grounding wire 4.

[0070] In this embodiment, when the staff uses the equipment disclosed in this invention to perform hanging and dismantling work at the preset points of the high-voltage line, the maintenance personnel first connect and fix the mounting rod 2 of the fixed hanging head 1 to the insulating rod 101. Then, with the help of the insulating rod 101, the hanging head 1 is hung on the preset work point of the high-voltage tower. After that, the staff accurately aligns the locking pin base 401 with the sliding circular groove 405 on the surface of the guide ring 201 and applies appropriate force to push it into the groove. Then, the staff rotates the knob 403 to make the two connect tightly and securely. After that, the maintenance personnel use wireless remote control to move the power device along the insulating rod 101 to the mounting rod 2. When the power device pushes the hanging and dismantling contact device... Upon reaching the top of the mounting rod 2, the device continues to climb, pushing the abutment ring 209 upwards. This causes the sliding block 206 to compress the pressure spring 204 and slide towards the top. After the sliding block 206 moves, the cylindrical sliding pin at the front end of the limiting plate 210 slides to the bottom of the groove 207. Subsequently, maintenance personnel use wireless remote control to move the power unit along the insulating rod 101 towards the bottom. The pressure spring 204 pushes the sliding block 206 along the mounting rod 2 until the bottom of the groove 207 abuts against the cylindrical sliding pin. This prevents the abutment ring 209 from moving and squeezes the tail of the mounting wing hook 202, causing it to close and engage with the mounting rod 2. The components include the mounting head 1, mounting rod 2, hook, and guide ring 2. A path is formed between 01 and grounding wire 4. Then, maintenance personnel use wireless remote control to move the power unit along the insulating rod 101 to the bottom for disassembly. At this point, the maintenance personnel have completed the connection work for grounding wire 4 at the pre-set work point on the high-voltage tower. Alternatively, if maintenance personnel need to remove grounding wire 4 from the pre-set work point on the high-voltage tower, they can first use wireless remote control to control the power unit to climb along the pre-reserved insulating rod 101 at the pre-set work point on the high-voltage tower until the power unit moves to the mounting rod 2. Then, the power unit continues to climb, pushing the abutment ring 209 to move the sliding block 206 to the top, causing the cylindrical sliding pin to disengage from the groove 2. At the tail tip of 07, maintenance personnel then use wireless remote control to lower the power unit along the insulating rod 101. The pressure spring 204 pushes the sliding block 206 to reset, the cylindrical sliding pin moves to the top of the groove 207, the abutment ring 209 resets, the mounting hook 202 opens and detaches from the mounting rod 2, and the hook-and-unhook contact device descends with the power unit until it reaches the bottom of the insulating rod 101 for disassembly by maintenance personnel. In this way, maintenance personnel complete the removal of the grounding wire 4 at the preset work point of the high-voltage tower. The time required for workers to complete the connection and removal of the grounding wire 4 at the preset work point of the high-voltage tower without using this device is shown in Table 1-1.

[0071]

[0072]

[0073] Table 1-1

[0074] Meanwhile, Table 1-2 shows the time required for staff to complete the connection and removal of grounding wire 4 at the preset work point of the high-voltage tower without climbing, using this device.

[0075]

[0076]

[0077] Table 1-2

[0078] A comparison of Tables 1-1 and 1-2 shows that the non-height grounding wire hanging and removing device not only avoids working at heights, improving operational standardization and personnel safety, but also significantly shortens switching operation time. The hanging time is reduced to 50.5% of the original, and the removal time is reduced to 58.8%, both meeting the target of less than 70% of the original time. See details below. Figure 12 As shown, this invention selects 20 sets of grounding wires 4 at different voltage levels and performs 20 grounding wire 4 hanging and unhanging tests to observe whether the device works reliably. Battery life is also recorded, and the specific test results are as follows. Figure 13 As shown, the grounding wire 4 hanging and removing device developed by this invention can complete the work of hanging and removing the grounding wire 4, which originally required climbing, without climbing. It also reduces the working time of hanging the grounding wire 4 by 49% and the working time of removing the grounding wire 4 by 42%, respectively, reducing the workload of the workers. The device has 100% reliability and is suitable for grounding points of various voltage levels.

[0079] Example 2:

[0080] In this embodiment, the staff conducted tests based on the hook-and-unhook contact device disclosed in Embodiment 1. This device uses a circular, uniform array design for the number of mounting blades. Comparison revealed that existing hook-and-unhook contact devices only have two mounting blades, symmetrically distributed. By comparing the data in Tables 1-5, which show the number of hooks released when 200 hook-and-unhook contact devices with different hook numbers were used under wind tunnel testing conditions of different wind speeds (wind speeds 3 and 9 are listed in this embodiment), with a 20kg counterweight attached, the results are as follows.

[0081]

[0082] Table 1-5

[0083] A detailed analysis of the figures clearly shows that the decoupling probability decreases significantly with the increase in the number of hooks. Furthermore, the overall decoupling probability of the mounting platform decreases noticeably with an increase in the number of hooks, especially when the number of hooks is small, such as only 2 to 3, where the decoupling probability is relatively high and the mounting platform is more prone to detachment from the hooks. However, when the number of hooks increases to four, the downward trend in the decoupling probability gradually flattens and stabilizes. Increasing the number of hooks can effectively reduce the risk of decoupling to a certain extent, thereby significantly improving the reliability and safety of the system. Based on this, the scheme of using four mounting wings in a uniform ring array adopted in this invention has, in practical applications, resulted in a decoupling probability significantly lower than the internally set target of 1%. Compared with existing technologies, it represents a qualitative leap in system reliability and safety.

[0084] Example 3:

[0085] In this embodiment, based on the mounting rod 2 disclosed in Embodiment 1, a tab mechanism is added. The mounting rod 2 has a square groove 8 inside, and a soft spring 801 is fixed inside the square groove 8. A tab 802 is fixed to the side end of the soft spring 801, and the surface of the tab 802 is slidably connected to the inside of the square groove 8. This increases the contact area between the mounting rod 2 and the mounting / unmounting contact device. We tested the number of tabs 802 and obtained the key data shown in Tables 1-6.

[0086]

[0087] Table 1-6

[0088] The formula for calculating conductivity stability is: Conductivity stability (measured by resistance change rate) = ((final resistance - initial resistance) / initial resistance) × 100%. This is a quantitative indicator used to describe the stability of the conductivity of a conductive material or component under certain conditions (such as changes in time, temperature, current, etc.). The smaller the resistance change rate, the better the conductivity stability, meaning that the conductivity of the material or component is less affected by external factors and can maintain a relatively stable conductivity state over a long period. Conversely, the larger the resistance change rate, the worse the conductivity stability, and the easier it is for the conductivity to change. Initial resistance refers to the resistance value of a conductive material or component before it is used or tested, that is, the resistance in its initial state (usually including no power supply, no influence from other external environmental factors, or standard test starting conditions). Final resistance refers to the resistance value exhibited by a conductive material or component after a certain period of time and under certain conditions (such as long-term power supply, experiencing a certain temperature change, or being subjected to a certain mechanical stress). For example, when conducting a long-term power supply test on a section of conductive material, the initial resistance R0 is recorded as 10Ω. After a period of time, the final resistance R is measured. t If the resistance is 10.5Ω, then the conductivity stability (resistance change rate) = (10.5-10) / 10×100% = 5%, which directly reflects the degree of resistance change of the material during the current carrying process. From the key data presented in Table 1-6, it can be clearly seen that as the number of tabs 802 increases, the contact area gradually expands from 0.1 square centimeters to 1.0 square centimeters, and the conductivity stability shows a significant upward trend. Measured by the resistance change rate, the value continuously decreases. This larger conductive area means that the current flows more smoothly and stably. In actual use scenarios, in order to ensure the safe operation of the line and the safety of the operators, it is generally required that the resistance change rate be as small as possible, usually not exceeding 5%. This device uses eight tabs 802, making its conductivity stability far lower than the required 5%. This ensures that even if the contact device encounters adverse effects such as external vibration or impact, the mounting rod 2 maintains a tight fit, thereby ensuring continuous and stable current transmission. This excellent performance gives the device a significant advantage in reliability.

The grounding wire device without the need for climbing as described in claim 1, characterized in that: The groove (207) includes an outer tip (2071), an inner tip (2072), an inner tail end (2073), an outer tail end (2074), a first inner end (2075), a first outer end (2076), a second inner end (2077), and a second outer end (2078). When the device connects to the grounding wire (4), as the power device moves along the insulating rod (101) towards its top, the cylindrical sliding pin moves from the outer tip (2071) to the inner tip (2072), and then the power device continues to move towards the top of the insulating rod (101). When pushed, the cylindrical sliding pin moves from the inner tip (2072) along the inner side of the groove (207) to the first inner end (2075), then moves to the first outer end (2076), until it moves along the outer side of the groove (207) to the outer tail end (2074). Then the power device moves to the bottom of the insulating rod (101). As the sliding block (206) moves to the bottom of the insulating rod (101) with the help of the pressure spring (204), the cylindrical sliding pin moves from the outer tail end (2074) to the inner tail end (2073). At this time, the device is connected to the grounding wire (4). When the device removes the grounding wire (4), the power device moves to the top of the insulating rod (101) again. At this time, the cylindrical sliding pin moves from the inner tail end (2073) to the second outer side end (2078). Then the power device moves from the top of the insulating rod (101) to the tail end. The cylindrical sliding pin moves along the outside of the groove (207) from the second outer side end (2078) to the outer tip (2071) to reset. At this time, the device has completed the removal of the grounding wire (4).
