Description

Technical Field

[0001] This invention relates to the field of electrical wire maintenance technology, and in particular to a fixing device for preventing the displacement of a shock absorber and a drone installation system. Background Technology

[0002] During the operation of high-voltage transmission lines, conductors experience high-frequency vibrations under wind force, which can lead to fatigue fracture over time. Vibration dampers are crucial hardware installed on conductors to absorb vibration energy and suppress light wind vibrations. However, after long-term operation, vibration dampers may shift from their initial installation position due to external forces such as vibration and icy wind loads, significantly weakening their vibration damping effect and even damaging the conductors themselves.

[0003] Currently, the repositioning or replacement of displacement vibration dampers mainly relies on manual high-altitude operations or power outage maintenance. This method is not only inefficient and costly, but more importantly, it exposes workers directly to ultra-high voltage electric fields, posing a significant risk of electric shock and falls, creating immense safety pressure. Furthermore, traditional fixing devices often have simple structures and unreliable clamping force, easily loosening again under continuous conductor vibration, failing to achieve long-term effective fixation. Although there have been attempts to use drones for transportation and assisted installation, achieving reliable triggering, automatic clamping, and persistent locking of the device on the conductor remains a pressing technical challenge. Summary of the Invention

[0004] The main objective of this invention is to provide a fixing device and UAV installation system for preventing vibration damper displacement. This addresses the issue that after long-term operation, vibration dampers may shift from their initial installation position due to external forces such as vibration and icy wind loads, significantly weakening their vibration damping effect and even damaging the conductors themselves. Furthermore, the repositioning or replacement of displaced vibration dampers primarily relies on manual high-altitude operations or power outage maintenance. This method is not only inefficient, but also exposes workers directly to ultra-high voltage electric fields, posing a high risk of electric shock and falls.

[0005] To achieve the above-mentioned objective, the first aspect of the present invention provides a fixing device for preventing the displacement of the anti-vibration hammer, including a clamping assembly, a locking assembly, a hooking and triggering assembly, and a hanger. The clamping assembly includes an arc-shaped clamping block slidably connected to the hanger and a lead screw rotatably connected to the hanger. A nut is fixedly installed in the center hole of the arc-shaped clamping block. The nut matches the external thread of the lead screw. By rotating the lead screw, the arc-shaped clamping block is driven to move closer to or away from the hanger. When the arc-shaped clamping block moves closer to the hanger, it clamps the wire. When the arc-shaped clamping block moves away from the hanger, it releases the wire. The locking assembly includes a nut locking block, a preload spring, a pin, and a pull rope. The nut locking block is located on the arc-shaped clamping block. The preload spring is installed between the cavity formed by the nut locking block and the arc-shaped clamping block. The pin is inserted from the surface of the nut locking block to the bottom of the arc-shaped clamping block. Under the action of the nut locking block, the other end of the preload spring is supported on the thread of the lead screw to lock the lead screw. The attachment and triggering assembly includes a throwing mechanism connecting rod, a guide plate, a guide frame, and a frame. The throwing mechanism connecting rod is used to connect with the UAV. The guide plate and guide frame located on the fixed device are used to guide the wire into the arc-shaped clamping blocks. The frame is rotatably connected to one end of the lead screw. The frame is fixedly connected to the hanger, and a trigger spring for applying force to the arc-shaped clamping blocks is installed on the frame.

[0006] Furthermore, one end of the pull rope is connected to the pin, and the other end is used to connect to the remote control throwing mechanism of the drone. By remotely pulling the pull rope to pull out the pin, the lock is released, the nut locking block disengages from the arc-shaped clamping block, and the preload spring disengages from the threaded support of the lead screw, thereby realizing the release of the lead screw from the lock.

[0007] Furthermore, it also includes a buffer and anti-slip assembly, which includes a bearing and an anti-slip protective pad disposed inside the arc-shaped clamping block. The bearing is sleeved on both ends of the lead screw to reduce the rotational resistance of the lead screw. The frame is rotatably connected to the lead screw through one of the bearings. The anti-slip protective pad is made of polyurethane material and is used to buffer the clamping force and enhance the friction with the wire.

[0008] Furthermore, the arc-shaped profile of the arc-shaped clamping block can be adapted to wires of different diameters, with the wire diameter ranging from 20 to 50 mm.

[0009] Furthermore, the preload spring is always in a compressed state to provide lateral thrust, which causes the nut locking block to be pushed out of the arc-shaped clamping block after the pin is disengaged, and the lead screw is disengaged from the lock.

[0010] Furthermore, the attachment and triggering component also includes a quick docking structure located at the top of the throwing mechanism connecting rod, for quick connection and disconnection with the damping joint of the UAV; The guide plate is fixedly installed on one end of the arc-shaped clamping block and is used to guide the wires into the arc-shaped clamping block during the installation of the UAV; The guide frame is fixedly connected to the hanger and is used to further guide the wires to accurately enter the arc-shaped clamping block during the installation of the UAV.

[0011] The second aspect of this paper proposes a drone installation system for installing a fixing device as described above to prevent the vibration damper from shifting, including the drone body, an image transmission auxiliary observation device, a damping joint, and a remote control throwing mechanism. The drone body is used to carry a fixed device; The image transmission auxiliary observation device is installed on the UAV body and is used to transmit the position information of the guide wire and the anti-vibration hammer in real time. The damping joint is located between the drone body and the throwing mechanism connecting rod of the fixed device, and is used to counteract the shaking of the drone when it is hovering. The remote-controlled throwing mechanism is connected to the pull rope of the fixed device, which is used to remotely control the pull rope to pull out the pin and trigger the locking screw of the locking assembly.

[0012] Furthermore, the drone body is an industrial-grade multi-rotor drone, and its surface is provided with an electromagnetic shielding material layer to resist interference from ultra-high voltage electric fields. The damping joint can rotate 360° and deflect ±15°, ensuring precise connection between the fixing device and the wire.

[0013] Furthermore, the image transmission-assisted observation device includes a high-definition zoom camera and an infrared thermal imager, which are used to provide visualization and thermal imaging information during installation to assist ground operators in positioning.

[0014] Furthermore, the remote-controlled throwing mechanism includes a motor and a rope reel. The rope reel is connected to the pull rope. The motor is controlled by a ground remote controller to pull the pull rope to remove the pin, triggering the fixing device to clamp the wire.

[0015] Beneficial effects: 1. The fixing device and UAV installation system for preventing vibration damper displacement of the present invention, through the synergistic action of clamping components, locking components, and hooking and triggering components, achieves full automation of the device from carrying, positioning, triggering to final locking. After the UAV transports the device to the designated location, the locking component can be triggered to release via remote command, thereby driving the clamping component to automatically and firmly grip the wire. Its screw and nut mechanism has inherent self-locking characteristics, which can effectively resist long-term vibration and fundamentally prevent the vibration damper from shifting again, achieving reliable one-time installation without manual climbing.

[0016] 2. The fixing device and UAV installation system for preventing vibration damper displacement of the present invention achieves remote and precise release of the locked state through the linkage design of the pull rope and the UAV remote control throwing mechanism. This allows ground operators to control the key steps of the entire installation process from a safe distance, completely avoiding high-risk manual operation under high-voltage electric fields, and greatly improving the safety and controllability of the operation.

[0017] 3. The anti-vibration hammer fixing device and UAV installation system of the present invention have a buffer and anti-slip component that provides dual protection. The bearing effectively reduces the rotation resistance of the lead screw, ensuring smooth operation; while the polyurethane anti-slip protective pad provides high friction while buffering the clamping force with its elastic material, avoiding hard pressure damage or plating damage to the wire surface caused by the metal clamp, thus effectively protecting the wire.

[0018] In summary, this invention solves the problem of conductor fatigue damage caused by vibration damper displacement, and at the same time achieves efficient, low-cost, all-terrain coverage unmanned maintenance through UAV technology, which has significant economic benefits and engineering application value.

[0026] Example 1 Reference Figures 1-7 This embodiment provides a fixing device to prevent the vibration damper from shifting, including a clamping assembly 1, a locking assembly 2, a hooking and triggering assembly 4, and a bracket 5; The clamping assembly 1 includes an arc-shaped clamping block 11 slidably connected to the hanger 5 and a lead screw 12 rotatably connected to the hanger 5. A nut 7 is fixedly installed in the center hole of the arc-shaped clamping block 11. The nut 7 matches the external thread of the lead screw 12. By rotating the lead screw 12, the arc-shaped clamping block 11 is driven to move closer to or away from the hanger 5. When the arc-shaped clamping block 11 moves closer to the hanger 5, it clamps the wire 700. When the arc-shaped clamping block 11 moves away from the hanger 5, it releases the wire 700. The locking assembly 2 includes a nut locking block 21, a preload spring 22, a pin 23, and a pull rope 24. The nut locking block 21 is located on the arc-shaped clamping block 11. The preload spring 22 is installed between the cavity formed by the nut locking block 21 and the arc-shaped clamping block 11. The pin 23 is inserted from the surface of the nut locking block 21 to the bottom of the arc-shaped clamping block 11. Under the action of the nut locking block 21, the other end of the preload spring 22 is supported on the thread of the lead screw 12 to lock the lead screw 12. The attachment and triggering assembly 4 includes a throwing mechanism connecting rod 41, a guide plate 42, a guide frame 43, and a frame 45. The throwing mechanism connecting rod 41 is used to connect with the UAV. The guide plate 42 and the guide frame 43, located on the fixing device, are used to guide the wire 700 into the arc-shaped clamping blocks 11. The frame 45 is rotatably connected to one end of the lead screw 12. The frame 45 is fixedly connected to the hanger 5, and a trigger spring 46 for applying force to the arc-shaped clamping blocks 11 is installed on the frame 45.

[0027] In this embodiment, the clamping assembly 1 includes an arc-shaped clamping block 11 and a lead screw 12. The arc-shaped clamping block 11 is mounted on the hanger 5 via a sliding connection and can move linearly along the guide groove of the hanger 5. The lead screw 12 is rotatably connected to the hanger 5 via a bearing 32, and its axis is parallel to the movement direction of the arc-shaped clamping block 11. A nut 7 is fixedly installed in the central hole of the arc-shaped clamping block 11, and the nut 7 matches the external thread of the lead screw 12. By rotating the lead screw 12, the nut 7 drives the arc-shaped clamping block 11 to move along the hanger 5, allowing the arc-shaped clamping block 11 to move closer to or further away from the hanger 5. When the arc-shaped clamping block 11 is close to the hanger 5, it cooperates with the hanger 5 to form a clamping space, thereby clamping the wire 700; when the arc-shaped clamping block 11 is away from the hanger 5, the clamping space expands, thereby releasing the wire 700.

[0028] The locking assembly 2 includes a nut locking block 21, a preload spring 22, a pin 23, and a pull rope 24. The nut locking block 21 is located on the arc-shaped clamping block 11, specifically embedded in the groove of the arc-shaped clamping block 11. The preload spring 22 is installed between the cavity formed by the nut locking block 21 and the arc-shaped clamping block 11 and is always in a compressed state. The pin 23 is inserted into the surface of the nut locking block 21 and extends to the bottom of the arc-shaped clamping block 11 to fix the position of the nut locking block 21. Under the action of the nut locking block 21, the other end of the preload spring 22 is supported on the thread of the lead screw 12, thereby locking the lead screw 12 and preventing its accidental rotation.

[0029] The attachment and triggering assembly 4 includes a throwing mechanism connecting rod 41, a guide plate 42, a guide frame 43, and a frame 45. The throwing mechanism connecting rod 41 is fixed to the frame 45 and is used to connect with the UAV to enable the carrying and positioning of the device. The guide plate 42 and the guide frame 43 are respectively fixedly installed on the arc-shaped clamping block 11 and the hanger 5, and are used to guide the wire 700 to accurately enter the clamping area between the arc-shaped clamping blocks 11 during installation. The frame 45 is rotatably connected to one end of the lead screw 12 through a bearing 32. A trigger spring 46 is installed on the frame 45. One end of the trigger spring 46 acts on the arc-shaped clamping block 11 to apply an initial force to the arc-shaped clamping block 11 after the lock is released, thereby promoting the clamping action.

[0030] Optionally, one end of the pull rope 24 is connected to the pin 23, and the other end is used to connect to the remote control throwing mechanism 500 of the drone. By remotely pulling the pull rope 24 to pull out the pin 23 to release the lock, the nut locking block 21 disengages from the arc-shaped clamping block 11, and the preload spring 22 disengages from the threaded support of the lead screw 12, thereby realizing the release of the lead screw 12 from the lock.

[0031] It should be noted that one end of the pull rope 24 of the locking assembly 2 is connected to the pin 23, and the other end is used to connect to the remote-controlled throwing mechanism 500 of the drone. By remotely controlling the remote-controlled throwing mechanism 500 to pull the pull rope 24, the pin 23 is pulled out, thereby releasing the fixation on the nut locking block 21. At this time, the elastic force of the preload spring 22 pushes the nut locking block 21 away from the arc-shaped clamping block 11, and the preload spring 22 simultaneously releases its support for the thread of the lead screw 12, realizing the release of the lead screw 12 from the locked state. This achieves remote triggering of locking release, avoiding the risks of manual high-altitude operation. It makes the locking release process fast and reliable, suitable for unmanned operation in complex environments.

[0032] Optionally, it also includes a buffer anti-slip component 3, which includes a bearing 32 and an anti-slip protective pad 31 disposed inside the arc-shaped clamping block 11. The bearing 32 is sleeved on both ends of the lead screw 12 to reduce the rotational resistance of the lead screw 12. The frame 45 is rotatably connected to the lead screw 12 through one of the bearings 32. The anti-slip protective pad 31 is made of polyurethane material and is used to buffer the clamping force and enhance the friction with the wire 700.

[0033] It should be noted that the buffer anti-slip assembly 3 also includes bearings 32 sleeved at both ends of the lead screw 12 to reduce rotational resistance; the anti-slip protective pad 31 is made of polyurethane material to buffer clamping force and enhance friction.

[0034] The bearing 32 reduces the mechanical resistance when the lead screw 12 rotates, improving the adjustment efficiency; the polyurethane material has both elasticity and wear resistance, which can protect the surface of the wire 700 and adapt to the friction requirements of different wire 700 materials; the anti-slip protective pad 31 reduces the damage of clamping force to the wire 700 and extends its service life.

[0035] Optionally, the arc-shaped profile of the arc-shaped clamping block 11 can adapt to wires 700 of different diameters, with the wire 700 diameter ranging from 20-50mm; the arc-shaped profile of the arc-shaped clamping block 11 is designed to adapt to wires 700 of different diameters, with the applicable wire 700 diameter range being 20-50mm. The curvature of the arc-shaped clamping block 11 has been optimized and calculated to ensure surface contact with the surface of the wire 700 during the clamping process. Guide screws 8 are fixedly connected to both sides of the arc-shaped clamping block 11, and the guide screws 8 are slidably connected in the strip groove on the bracket 5. The guide screws 8 can ensure that the arc-shaped clamping block 11 has stable lifting and moving performance during the lifting process.

[0036] Optionally, the preload spring 22 is always in a compressed state to provide lateral thrust, so that after the pin 23 is disengaged, the nut locking block 21 is pushed out from the arc-shaped clamping block 11, and the lead screw 12 is disengaged.

[0037] It should be noted that the preload spring 22 is always in a compressed state, providing lateral thrust. After the pin 23 disengages, the elastic force of the preload spring 22 pushes the nut locking block 21 off the arc-shaped clamping block 11, simultaneously disengaging the preload spring 22 from the thread of the lead screw 12, thus disengaging the lead screw 12 from the locking mechanism. The continuous compression of the preload spring 22 ensures the stability of the locking force, preventing it from loosening even under long-term vibration conditions.

[0038] Optionally, the attachment and triggering component 4 also includes a quick docking structure 44, located at the top of the throwing mechanism connecting rod 41, for quick connection and disconnection with the damping joint 400 of the UAV; The guide plate 42 is fixedly installed on one section of the arc-shaped clamping block 11 and is used to guide the wire 700 into the arc-shaped clamping block 11 during the installation of the UAV. The guide frame 43 is fixedly connected to the hanger 5 and is used to further guide the wire 700 to accurately enter the arc-shaped clamping block 11 during the installation of the UAV.

[0039] It should be noted that the throwing mechanism connecting rod 41 is used to connect with the damping joint 400 of the UAV body 200. The quick docking structure 44 is located on the top of the throwing mechanism connecting rod 41, enabling quick connection and disconnection with the UAV. The guide plate 42 is fixedly installed at one end of the arc-shaped clamping block 11, and the guide frame 43 is fixedly connected to the hanger 5. The two work together to guide the wire 700 accurately into the arc-shaped clamping block 11 during UAV installation, avoiding misalignment. The quick docking structure 44 improves the connection efficiency between the UAV and the fixed device, shortening the operation time; the directional guidance function of the guide plate 42 reduces the installation deviation of the wire 700, improving the installation accuracy.

[0040] Example 2 Reference Figure 1 An embodiment of the present invention provides a drone installation system for installing the fixing device for preventing the vibration damper from shifting, including a drone body 200, an image transmission auxiliary observation device 300, a damping joint 400, and a remote control throwing mechanism 500. The UAV body 200 is used to carry a fixing device; The image transmission auxiliary observation device 300 is mounted on the UAV body 200 and is used to transmit the position information of the wire 700 and the anti-vibration hammer 600 in real time. The damping joint 400 is located between the UAV body 200 and the throwing mechanism connecting rod 41 of the fixed device, and is used to counteract the shaking of the UAV when it is hovering. The remote-controlled throwing mechanism 500 is connected to the pull rope 24 of the fixed device, and is used to remotely control the action of the pull rope 24 to pull out the pin 23 and trigger the locking screw 12 of the locking assembly 2.

[0041] It should be noted that the drone installation system includes the drone body 200, an image transmission auxiliary observation device 300, a damping joint 400, and a remote-controlled throwing mechanism 500. The drone body 200 carries a fixing device; the image transmission auxiliary observation device 300 transmits real-time position information of the guide wire 700 and the anti-vibration hammer 600; the damping joint 400 counteracts the drone's hovering sway; and the remote-controlled throwing mechanism 500 triggers the locking assembly 2 to lock the screw 12 via the pull rope 24. The image transmission auxiliary observation device 300 provides real-time visual information, improving the safety of operations in high-risk environments; the sway suppression function of the damping joint 400 ensures precise alignment between the fixing device and the guide wire 700; and the remote-controlled throwing mechanism 500 enables remote operation, reducing the risk of human intervention.

[0042] Optionally, the UAV body 200 is an industrial-grade multi-rotor UAV with a payload of not less than 5kg, a wind resistance level of not less than level 6, and an electromagnetic shielding design to resist interference from ultra-high voltage electric fields. The damping joint 400 can rotate 360° and deflect ±15°, ensuring precise docking between the fixing device and the wire 700.

[0043] It should be noted that the UAV body 200 is an industrial-grade multi-rotor UAV with a payload of ≥5kg, wind resistance of ≥6, and electromagnetic shielding design; the damping joint 400 can rotate 360° and deflect ±15°. The high payload and wind resistance of the industrial-grade UAV meet the operational needs of complex environments; the electromagnetic shielding design prevents interference from ultra-high voltage electric fields with the UAV control system; and the flexible range of motion of the damping joint 400 meets the installation requirements at different angles.

[0044] Optionally, the image transmission auxiliary observation device 300 includes a high-definition zoom camera 301 and an infrared thermal imager 302, which are used to provide visualization and thermal imaging information during the installation process to assist ground operators in positioning.

[0045] It should be noted that the image transmission auxiliary observation device 300 includes a high-definition zoom camera 301 and an infrared thermal imager 302, providing visualization and thermal imaging information. The high-definition zoom camera 301 assists in precise alignment, and the infrared thermal imager 302 detects abnormal temperatures in the wire 700, providing early warning of potential faults.

[0046] Optionally, the remote-controlled throwing mechanism 500 includes a motor and a rope reel. The rope reel is connected to the pull rope 24. The motor is controlled by a ground remote controller to pull the pull rope 24 to pull out the pin 23, triggering the fixing device to clamp the wire 700.

[0047] It should be noted that the remote-controlled throwing mechanism 500 includes a motor and a rope reel. The rope reel is connected to the pull rope 24, and the motor is controlled by a ground remote controller to pull the pull rope 24. The combination of the motor and the rope reel enables remote and precise control, improving the operational response speed; the ground remote controller operation reduces the risks of working at heights and improves overall operational efficiency.

[0048] The image transmission auxiliary observation device 300 includes a high-definition zoom camera 301 and an infrared thermal imager 302.

[0049] Instructions: First, reliably connect the fixing device to the damping joint 400 below the drone via the quick-connect structure 44 of its hook and trigger assembly 4. Simultaneously, connect the other end of the pull rope 24 of the locking assembly 2 to the remote-controlled throwing mechanism 500 mounted on the drone. At this point, the locking assembly 2 is in the locked state, i.e., the pin 23 is inserted, the preload spring 22 is compressed and presses against the thread of the lead screw 12, preventing the lead screw 12 from rotating, thus keeping the arc-shaped clamping block 11 in the open state.

[0050] The drone, carrying the fixed device, flies towards the target guide wire 700. The operator, using the real-time image transmitted from the drone's image transmission auxiliary observation device 300, precisely controls the drone to align the guide opening formed by the guide plate 42 and guide frame 43 of the fixed device with the guide wire 700. The damping joint 400 effectively counteracts the drone's own sway during this process, ensuring stable alignment between the device and the guide wire 700.

[0051] The drone continues its advance, with the guide wire 700 sliding along the inclined surface of the guide plate 42 and, further guided by the guide frame 43, accurately entering the clamping area between the open arc-shaped clamping block 11 and the hanger 5. Once the guide wire 700 is confirmed to be correctly positioned, the ground operator triggers the remote-controlled throwing mechanism 500 via remote control. The motor of this mechanism starts, retracting the pull rope 24. The tension of the pull rope 24 pulls the pin 23 out of the nut locking block 21, releasing the mechanical constraint on the nut locking block 21. Under the accumulated elastic force of the preload spring 22, the nut locking block 21 is quickly pushed away from its original position. This action causes the end of the preload spring 22 to disengage from the threaded contact of the lead screw 12, instantly releasing the rotational locking of the lead screw 12.

[0052] As the lock is released, the trigger spring 46 in the engagement and trigger assembly 4 begins to function. The trigger spring 46 pushes the arc-shaped clamping block 11, giving it an initial tendency to move closer to the wire 700. Since the lead screw 12 is unlocked, the arc-shaped clamping block 11, with the threaded engagement of the embedded nut 7 and the lead screw 12, causes the lead screw 12 to rotate, and the arc-shaped clamping block 11 moves towards the wire 700.

[0053] The arc-shaped clamping block 11 continues to move until its inner anti-slip protective pad 31 firmly grips the wire 700. The polyurethane anti-slip protective pad 31 provides sufficient friction to prevent the device from sliding and also cushions the clamping force to avoid damaging the surface of the wire 700. It will not rotate in the opposite direction without external torque, effectively resisting loosening caused by external forces such as wind vibration, thereby achieving reliable limiting of the vibration damper 600.

[0054] After clamping is complete, the drone detaches from the quick-connect structure 44 via a release mechanism, leaving the anchoring device alone on the guide wire 700. After separating from the anchoring device, the drone safely returns to the ground under operator control.
