Description

Technical Field

[0001] This invention belongs to the technical field of line maintenance equipment, specifically relating to a high-precision broken strand inspection and repair device and its usage method. Background Technology

[0002] As the "main artery" of the power system, transmission lines are exposed to complex outdoor environments for extended periods, making them susceptible to erosion from natural factors such as wind, rain, snow, and corrosion. This can lead to conductor breakage, where one or more of the multiple aluminum or steel wires that make up the conductor break. If not addressed promptly, the breakage can spread, eventually causing serious accidents such as conductor fracture and power outages, resulting in enormous economic losses and social impact.

[0003] Inspection personnel must use ground-based telescopes, drones, or even foot patrols along the route to discover defects. This method not only covers a small area but is also greatly affected by weather and terrain, and is subject to visual limitations, making it prone to missed inspections or misjudgments. After a broken strand fault is discovered, power outages or equipotential bonding operations require personnel to travel by helicopter or use pulleys to reach the high-altitude site for repairs. This requires extremely high skill levels, carries significant operational risks, and is a lengthy process. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-precision strand breakage inspection and maintenance device and its usage method to solve the problems mentioned in the background art.

[0005] The objective of this invention is achieved as follows: a high-precision broken strand inspection and repair device, comprising a main body suspended above the line, a boom mounted on the upper side of the main body, a balance block fixedly mounted on the lower part of the main body, wheels on both the left and right sides of the main body, a motor mounted on the outside of the wheels, a detection mechanism on the left side of the main body, and a fastening mechanism inside the main body. The fastening mechanism includes a fastening seat, a telescopic cylinder fixedly mounted on the upper side of the fastening seat, a double-sided rack at the output end of the telescopic cylinder, symmetrically engaged grippers on the lower side of the fastening seat, a single-sided rack fixedly mounted on the upper side of the grippers, and symmetrically rotatable drive gears inside the fastening seat. The double-sided rack is located between the two drive gears, and both the double-sided rack and the single-sided rack mesh with the drive gears.

[0006] The boom is arc-shaped and located above the main body, which facilitates stable lifting by drones.

[0007] The main body is equipped with a monitoring camera for real-time monitoring.

[0008] A feeding hopper is located on the right side of the fastening mechanism, and a retrieval port is provided on the side of the feeding hopper. Clamps are placed inside the feeding hopper. The retrieval port facilitates the removal and replenishment of clamps inside the feeding hopper.

[0009] A pusher block is installed inside the feeding hopper, and a feeding spring is installed between the pusher block and the feeding hopper. The spring compresses the clamp through the pusher block, causing the clamp to move closer to the gripper of the fastening mechanism.

[0010] The detection mechanism includes symmetrically arranged semi-cylinders, each comprising an outer cylinder and an inner cylinder. The inner cylinder is hinged inside the outer cylinder. A return spring is provided between the ends of the inner and outer cylinders that are hinged together. A displacement sensor is provided at the end of the outer cylinder furthest from the return spring. The two semi-cylinders can be combined to form a complete cylinder.

[0011] The semi-cylinder is funnel-shaped, and the diameter of the end of the semi-cylinder that is hinged to the inner cylinder and the outer cylinder is smaller than the diameter of the other end.

[0012] The inner cylinder includes evenly spaced split plates, the positions of which correspond to the positions of the displacement sensors. Tensioning fabric is placed between the split plates. The tensioning fabric fills the gaps between the split plates and prevents broken metal wires from getting stuck between them.

[0013] Both of the two semi-cylinders are fixedly provided with racks on their upper sides, and both of the two semi-cylinders are provided with gears on their upper sides. Both racks mesh with the gears, which are driven by a motor.

[0014] A wire-straightening mechanism is provided between the detection mechanism and the fastening mechanism. The wire-straightening mechanism includes a housing, a wire-straightening motor is fixedly installed on the outside of the housing, a drive gear is provided at the output end of the wire-straightening motor, a wire-feeding port is provided on the lower side of the housing, an open toothed ring is rotatably provided inside the wire-feeding port, and a transmission gear is meshed between the open toothed ring and the drive gear.

[0015] The open toothed ring has uniformly arranged grooves inside. The grooves are engaged with the broken strands of metal wire.

[0016] A method for using a high-precision broken strand inspection and maintenance device includes the following steps: Step 1: Before use, ensure that the device is in normal working order. Use a drone to mount the entire device onto the line that needs to be repaired. Turn on the device power, and the walking motor will drive the walking wheels on the left and right sides to make the main body move smoothly along the line. Step 2: As the device moves forward, the detection mechanism continuously detects the circuit. When it moves to the vicinity of the broken strand of the circuit, the broken strand of metal wire will enter the trumpet-shaped half-cylinder, squeezing one or more split plates of the inner cylinder, causing the inner cylinder to rotate. The displacement sensor accurately detects the movement of the inner cylinder and transmits the signal back to the main control system. Step 3: After receiving the displacement sensor signal, the main control system starts the wire straightening mechanism. The wire straightening motor starts and drives the drive gear, which in turn drives the open toothed ring to rotate in the wire feeding port through the transmission gear. As the main body moves, the scattered broken strands of metal wire are combed and wound together and gathered into the main line. Step 4: Under the action of the feeding spring, the pusher inside the feeding hopper continuously pushes the outermost clamp towards the gripper. The gripper moves the clamp to the outside of the combed line, and the telescopic cylinder drives the gripper to close, firmly clamping the clamp at the break point. After the line break repair is completed, the device is removed by drone and the tools and equipment are retrieved.

[0017] The beneficial effects of this invention are: The main body can be mounted on the line by drone, and the left and right sides are equipped with walking wheels and walking motors, which can realize the autonomous movement of the device on the line, making it convenient to inspect and maintain different locations on the line, improving work efficiency, and reducing the risks and labor intensity of manual climbing of the line.

[0018] The detection mechanism adopts a symmetrical, trumpet-shaped semi-cylindrical structure. The inner cylinder consists of evenly spaced split plates corresponding to the positions of the displacement sensors. When a strand breaks in the circuit, the diameter of the broken strand changes, which squeezes the split plates, causing them to move. The displacement sensors detect this change in position, thus accurately determining whether a strand is broken and the extent of the breakage, providing an accurate basis for subsequent maintenance.

[0019] The wire-straightening motor drives the drive gear, which in turn drives the open-tooth ring to rotate through the transmission gear. The evenly spaced wire grooves inside the open-tooth ring can comb and straighten broken wire strands, keeping the wires neat during inspection and maintenance. This prevents messy wires from affecting inspection accuracy and maintenance operations, and improves the overall stability and reliability of the device.

[0020] In the fastening mechanism, the telescopic cylinder drives the double-sided rack to move, and the double-sided rack meshes with the drive gear, which in turn drives the single-sided rack meshing with the drive gear to move. This causes the symmetrically clamped jaws on the lower side of the fastening seat to move synchronously towards or away from each other, thereby achieving the clamping and repair of the broken strand. The feeding hopper automatically pushes the clamp to the pick-and-place port, making it convenient for the fastening mechanism to pick up the clamp during maintenance to fasten the broken strand, thus improving the convenience and efficiency of maintenance.

[0033] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0034] like Figure 1-4As shown, a high-precision broken strand inspection and repair device includes a main body 1, which is hung above the line 2. A boom 3 is provided on the upper side of the main body 1, and a balance block 5 is fixedly provided on the lower part of the main body 1. Traveling wheels 4 are provided on both the left and right sides of the main body 1, and a travel motor is installed on the outside of the traveling wheels 4. A detection mechanism 6 is provided on the left side of the main body 1. A fastening mechanism 7 is provided inside the main body 1. The fastening mechanism 7 includes a fastening seat 9. A telescopic cylinder 8 is fixedly provided on the upper side of the fastening seat 9. A double-sided rack 10 is provided at the output end of the telescopic cylinder 8. A gripper 11 is symmetrically engaged on the lower side of the fastening seat 9. A single-sided rack 12 is fixedly provided on the upper side of the gripper 11. A drive gear 13 is symmetrically rotatably arranged inside the fastening seat 9. The double-sided rack 10 is located between the two drive gears 13. Both the double-sided rack 10 and the single-sided rack 12 mesh with the drive gear 13.

[0035] A single telescopic cylinder 8 can precisely control the synchronous or opposite movement of the two grippers 11 through a double-sided rack 10 and two drive gears 13, ensuring the accuracy and stability of gripping and installing the clamp 15.

[0036] Furthermore, a feeding chamber 14 is provided on the right side of the fastening mechanism 7, and a pick-and-place port 16 is provided on the side of the feeding chamber 14. A clamp 15 is placed inside the feeding chamber 14.

[0037] Furthermore, a pusher block 17 is provided inside the feeding bin 14, and a feeding spring 18 is provided between the pusher block 17 and the feeding bin 14. The feeding bin 14 can accommodate multiple clamps 15, enabling the device to repair multiple broken strands in one inspection without frequent returns to replenish materials.

[0038] In use, the device is suspended above the line to be inspected via the boom 3. The traveling motor drives the traveling wheels 4, allowing the device to move autonomously along the line and enter inspection mode. The lower counterweight 5 ensures stability during movement and prevents tipping. The detection mechanism 6 on the left side of the device monitors the line status in real time; if a broken strand is detected, a signal is transmitted back to the main control system. The device can be remotely controlled, and operators can confirm the situation visually and through the main body's monitoring lens.

[0039] When a broken strand is confirmed, the fastening mechanism 7 is activated to reinforce the broken strand. Simultaneously with the device's movement and operation, the pusher 17 inside the feeding hopper 14, under the continuous pressure of the feeding spring 18, pushes the outermost clamp 15 towards the fastening mechanism 7, placing it in a ready-to-use state. The telescopic cylinder 8 of the fastening mechanism 7 pushes the double-sided rack 10 downwards. The double-sided rack 10 simultaneously drives two drive gears 13 to rotate. The drive gears 13 drive the single-sided rack 12 meshing with it and the connected gripper 11 to close synchronously towards the center, thus accurately gripping the clamp 15. The main body 1 moves above the broken strand, and the gripper 11 finally closes, firmly clamping the clamp 15 to the broken strand point and the periphery of the line, completing the repair. The telescopic cylinder retracts, and through the reverse transmission of the gears and racks, the gripper 11 opens and returns to its original position. Example 2

[0040] like Figure 1-9 As shown, a high-precision broken strand inspection and repair device includes a main body 1, which is hung above the line 2. A boom 3 is provided on the upper side of the main body 1, and a balance block 5 is fixedly provided on the lower part of the main body 1. Traveling wheels 4 are provided on both the left and right sides of the main body 1, and a travel motor is installed on the outside of the traveling wheels 4. A detection mechanism 6 is provided on the left side of the main body 1. A fastening mechanism 7 is provided inside the main body 1. The fastening mechanism 7 includes a fastening seat 9. A telescopic cylinder 8 is fixedly provided on the upper side of the fastening seat 9. A double-sided rack 10 is provided at the output end of the telescopic cylinder 8. A gripper 11 is symmetrically engaged on the lower side of the fastening seat 9. A single-sided rack 12 is fixedly provided on the upper side of the gripper 11. A drive gear 13 is symmetrically rotatably arranged inside the fastening seat 9. The double-sided rack 10 is located between the two drive gears 13. Both the double-sided rack 10 and the single-sided rack 12 mesh with the drive gear 13.

[0041] A single telescopic cylinder 8 can precisely control the synchronous or opposite movement of the two grippers 11 through a double-sided rack 10 and two drive gears 13, ensuring the accuracy and stability of gripping and installing the clamp 15.

[0042] Furthermore, a feeding chamber 14 is provided on the right side of the fastening mechanism 7, and a pick-and-place port 16 is provided on the side of the feeding chamber 14. A clamp 15 is placed inside the feeding chamber 14.

[0043] Furthermore, a pusher block 17 is provided inside the feeding bin 14, and a feeding spring 18 is provided between the pusher block 17 and the feeding bin 14. The feeding bin 14 can accommodate multiple clamps 15, enabling the device to repair multiple broken strands in one inspection without frequent returns to replenish materials.

[0044] Furthermore, the detection mechanism 6 includes symmetrically arranged semi-cylinders 19, each comprising an outer cylinder 24 and an inner cylinder 25. The inner cylinder 25 is hinged inside the outer cylinder 24. A return spring 26 is provided between the ends of the inner cylinder 25 and the outer cylinder 24 that are hinged together. A displacement sensor 27 is provided at the end of the outer cylinder 24 away from the return spring 26. The displacement sensor 27 directly senses the broken strand state through physical movement, rather than relying on image recognition which is susceptible to environmental interference, thus improving the accuracy and precision of the sensing.

[0045] Furthermore, the semi-cylinder 19 is funnel-shaped, with the diameter of the end of the semi-cylinder 19 closest to the inner cylinder 25 and hinged to the outer cylinder 24 being smaller than the diameter of the other end. This funnel-shaped semi-cylinder 19 design effectively detects loose, broken metal strands, significantly reducing the probability of missed detection.

[0046] Furthermore, the inner cylinder 25 includes evenly arranged split plates 28, the positions of the split plates 28 corresponding to the positions of the displacement sensors 27, and tension cloth 29 is arranged between the split plates 28.

[0047] Furthermore, a rack and pinion 20 is fixedly mounted on the upper side of each of the two semi-cylinders 19, and a gear 22 is mounted above each of the two semi-cylinders 19. The rack and pinion 20 mesh with the gear 22, which is driven by an opening and closing motor 21. By driving the gear 22 through the opening and closing motor 21, the rack and pinion 20 cause the semi-cylinders 19 to open and close, thereby clamping the circuit.

[0048] In another embodiment, the detection mechanism 6 is used to accurately detect the location and condition of broken strands in the line. Its structure is preferably as follows: before the main body 1 is hung on the line, the opening and closing motor 21 drives the two half cylinders 19 to move synchronously in opposite directions through the meshing of the gear 22 and the rack 20, thereby widening the distance between the two half cylinders 19. After the main body 1 is hung on the line, the two half cylinders 19 are then driven to close and enclose the line.

[0049] When there are no broken strands in the circuit, the split plates 28 are evenly distributed under the action of the return spring 26, the tension cloth 29 is flat, and the position signal of the split plates 28 detected by the displacement sensor 27 is stable without abnormal fluctuations. When a broken strand occurs in the circuit, the diameter of the circuit at the broken point increases locally or its shape changes, squeezing the split plates 28 in the inner cylinder 25, causing the split plates 28 to displace against the elastic force of the return spring 26. The displacement sensor 27 monitors the position change of the split plates 28 in real time. Since the positions of the split plates 28 are correspondingly set with the displacement sensors 27, each displacement sensor 27 can accurately capture the displacement of its corresponding split plate 28. Based on the displacement signal, the severity of the broken strand is assessed. The greater the displacement, the more severe the deformation of the circuit at the broken point, and the higher the degree of broken strand may be. The main control system feeds back the broken strand detection results to the operation terminal, prompting the operator with the location and degree of the broken strand in the circuit, providing a basis for subsequent maintenance operations. Example 3

[0050] like Figure 1-11 As shown, a high-precision broken strand inspection and repair device includes a main body 1, which is hung above the line 2. A boom 3 is provided on the upper side of the main body 1, and a balance block 5 is fixedly provided on the lower part of the main body 1. Traveling wheels 4 are provided on both the left and right sides of the main body 1, and a travel motor is installed on the outside of the traveling wheels 4. A detection mechanism 6 is provided on the left side of the main body 1. A fastening mechanism 7 is provided inside the main body 1. The fastening mechanism 7 includes a fastening seat 9. A telescopic cylinder 8 is fixedly provided on the upper side of the fastening seat 9. A double-sided rack 10 is provided at the output end of the telescopic cylinder 8. A gripper 11 is symmetrically engaged on the lower side of the fastening seat 9. A single-sided rack 12 is fixedly provided on the upper side of the gripper 11. A drive gear 13 is symmetrically rotatably arranged inside the fastening seat 9. The double-sided rack 10 is located between the two drive gears 13. Both the double-sided rack 10 and the single-sided rack 12 mesh with the drive gear 13.

[0051] A single telescopic cylinder 8 can precisely control the synchronous or opposite movement of the two grippers 11 through a double-sided rack 10 and two drive gears 13, ensuring the accuracy and stability of gripping and installing the clamp 15.

[0052] Furthermore, a feeding chamber 14 is provided on the right side of the fastening mechanism 7, and a pick-and-place port 16 is provided on the side of the feeding chamber 14. A clamp 15 is placed inside the feeding chamber 14.

[0053] Furthermore, a pusher block 17 is provided inside the feeding bin 14, and a feeding spring 18 is provided between the pusher block 17 and the feeding bin 14. The feeding bin 14 can accommodate multiple clamps 15, enabling the device to repair multiple broken strands in one inspection without frequent returns to replenish materials.

[0054] Furthermore, the detection mechanism 6 includes symmetrically arranged semi-cylinders 19, each comprising an outer cylinder 24 and an inner cylinder 25. The inner cylinder 25 is hinged inside the outer cylinder 24. A return spring 26 is provided between the ends of the inner cylinder 25 and the outer cylinder 24 that are hinged together. A displacement sensor 27 is provided at the end of the outer cylinder 24 away from the return spring 26. The displacement sensor 27 directly senses the broken strand state through physical movement, rather than relying on image recognition which is susceptible to environmental interference, thus improving the accuracy and precision of the sensing.

[0055] Furthermore, the semi-cylinder 19 is funnel-shaped, with the diameter of the end of the semi-cylinder 19 closest to the inner cylinder 25 and hinged to the outer cylinder 24 being smaller than the diameter of the other end. This funnel-shaped semi-cylinder 19 design effectively detects loose, broken metal strands, significantly reducing the probability of missed detection.

[0056] Furthermore, the inner cylinder 25 includes evenly arranged split plates 28, the positions of the split plates 28 corresponding to the positions of the displacement sensors 27, and tension cloth 29 is arranged between the split plates 28.

[0057] Furthermore, a rack and pinion 20 is fixedly mounted on the upper side of each of the two semi-cylinders 19, and a gear 22 is mounted above each of the two semi-cylinders 19. The rack and pinion 20 mesh with the gear 22, which is driven by an opening and closing motor 21. By driving the gear 22 through the opening and closing motor 21, the rack and pinion 20 cause the semi-cylinders 19 to open and close, thereby clamping the circuit.

[0058] Furthermore, a wire-straightening mechanism 30 is provided between the detection mechanism 6 and the fastening mechanism 7. The wire-straightening mechanism 30 includes a housing 31. A wire-straightening motor 32 is fixedly installed on the outside of the housing 31. A drive gear 34 is provided at the output end of the wire-straightening motor 32. A wire-feeding port 33 is provided on the lower side of the housing 31. An open toothed ring 36 is rotatably installed inside the wire-feeding port 33. A transmission gear 35 meshes between the open toothed ring 36 and the drive gear 34.

[0059] Furthermore, the open toothed ring 36 is provided with uniformly arranged wire grooves 37 inside.

[0060] A method for using a high-precision broken strand inspection and maintenance device includes the following steps: Step 1: Before use, ensure that the device is working properly, identify the line that needs to be repaired, and use a drone to mount the entire device onto the line that needs to be repaired. Turn on the device power, and the walking motor drives the walking wheels 4 on the left and right sides to make the main body 1 walk smoothly along the line. Step 2: As the device moves forward, the detection mechanism 6 continuously detects the line. When it moves to the vicinity of the broken strand of the line, the scattered broken strand of metal wire will enter the trumpet-shaped half-cylinder 19, squeezing one or more split plates 28 of the inner cylinder 25, causing the inner cylinder 25 to rotate. The displacement sensor 27 accurately detects the movement of the inner cylinder 25 and transmits the signal back to the main control system. Step 3: After receiving the signal from the displacement sensor 27, the main control system starts the wire straightening mechanism 30, the wire straightening motor 32 starts, drives the drive gear 34, and drives the open toothed ring 36 to rotate in the wire feeding port 33 through the transmission gear 35. As the main body 1 moves, the scattered broken strands of metal wire are combed and wound together and gathered into the main line. Step 4: Under the action of the feeding spring 18, the push block 17 inside the feeding bin 14 continuously pushes the outermost clamp 15 towards the gripper 11. The gripper 11 moves the clamp 15 to the outside of the combed line. The telescopic cylinder 8 drives the gripper 11 to close, firmly clamping the clamp 15 at the break point. After the line break repair is completed, the device is removed by drone and the tools and equipment are retrieved.

[0061] In another embodiment, a winding mechanism 30 is provided between the detection mechanism 6 and the fastening mechanism 7 to wind and organize broken strands of wire. Upon receiving a signal from the displacement sensor 27 and confirming a broken strand, the main control system controls the winding mechanism 30 to begin operation. The winding motor 32 starts, driving the drive gear 34, which in turn drives the open toothed ring 36 to rotate within the wire release port 33 via the transmission gear 35. The open position of the ring remains unchanged, ensuring the wire can smoothly enter the wire groove 37. As the device moves slowly, the broken strand passes through the rotating open toothed ring 36. With the rotation of the open toothed ring 36, the wire groove 37 drives the broken strand to rotate as well. During rotation, the wire groove 37 applies a uniform constraint force to the broken strand. The evenly distributed wire grooves 37 within the open toothed ring 36 effectively comb and wind the messy, loose broken strand into the unbroken main wire. The winding mechanism 30 ensures the integrity of the broken strand, allowing the subsequent clamps 15 to be tightened evenly and securely.

When it moves to the vicinity of the broken strand of the circuit, the broken strand of metal wire will enter the trumpet-shaped half-cylinder, squeezing one or more split plates of the inner cylinder, causing the inner cylinder to rotate. The displacement sensor accurately detects the movement of the inner cylinder and transmits the signal back to the main control system. Step 3: After receiving the displacement sensor signal, the main control system starts the wire straightening mechanism. The wire straightening motor starts and drives the drive gear, which in turn drives the open toothed ring to rotate in the wire feeding port through the transmission gear. As the main body moves, the scattered broken strands of metal wire are combed and wound together and gathered into the main line. Step 4: Under the action of the feeding spring, the pusher inside the feeding hopper continuously pushes the outermost clamp towards the gripper. The gripper moves the clamp to the outside of the combed line, and the telescopic cylinder drives the gripper to close, firmly clamping the clamp at the break point. After the line break repair is completed, the device is removed by drone and the tools and equipment are retrieved.
