Description

Technical Field

[0001] This invention relates to the field of cable repair equipment technology, and in particular to a fault repair device for high-voltage transmission lines. Background Technology

[0002] Electricity generated by power plants needs to be pressurized before being transmitted to various regions via high-voltage conductors. During power transmission, these conductors are exposed to sunlight and rain for extended periods, which can easily cause surface cracks. Furthermore, the high altitude and gravity-induced sag of the conductors can lead to fatigue and aging. Therefore, maintenance personnel need to regularly inspect and replace damaged cables to ensure safe power transmission. In addition, the outdoor environment can easily cause cables to snag on foreign objects.

[0003] The excessive length of high-voltage power lines and outdoor high-altitude operations often lead to missed areas during maintenance, resulting in incomplete inspections and potential risks. Existing inspection methods rely on manual checks, which are inefficient, and the risk of personal injury is high when replacing power lines.

[0004] Based on this, the present invention provides a fault detection and repair device for high-voltage transmission lines. Summary of the Invention

Detailed Implementation

[0030] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-15As shown, a high-voltage transmission line fault repair device includes a clamping mechanism 1. The clamping mechanism 1 includes a pair of upper clamping rods 101 and lower clamping rods 103, which are connected by an electric push rod. The lower clamping rods 103 are T-shaped rods with rectangular bottoms. The bottoms of the two lower clamping rods 103 are in contact with each other and are mirror images of each other. Multiple clamping rollers 102 are laterally rotatably mounted on the bottom of the upper clamping rods 101 and the top of the lower clamping rods 103. Clamping rollers 102 are arranged in an alternating pattern. Each clamping roller is a frustum-shaped cone with an inclined surface. The clamping rollers 102 are used to clamp high-voltage conductors, allowing the equipment to move along the conductors. By using two alternating clamping rollers 102 to clamp the high-voltage conductors, a slight bending effect is created, making cracks and damage on the line easier to detect. Multiple clamping pulleys 116 are laterally mounted on the outer ring of each clamping roller 102. The axes of the clamping pulleys 116 are perpendicular to the axes of the clamping rollers 102. The clamping pulleys 116 provide friction to the clamping rollers 102 as the equipment moves forward, preventing damage from impacts. To prevent slippage during forward movement, the top of the lower clamping rod 103 is provided with multiple wire grooves to provide movement space for bent wires. Gears are fixedly installed at both ends of the clamping roller 102. A first motor 104 is fixedly installed on the upper clamping rod 101, and gears are fixedly installed on the first motor 104. The gears on the first motor 104 are connected to the clamping roller 102 rotatably mounted on the upper clamping rod 101 via a rack and pinion belt. A second motor 105 is fixedly installed on the lower clamping rod 103, and gears are fixedly installed on the second motor 105. The gears on the second motor 105 are connected to the lower clamping roller 102 rotatably mounted on the upper clamping rod 101 via a rack and pinion belt. The clamping rollers 102 rotatably mounted on the rod 103 are connected by a rack and pinion belt. By activating the electric push rod on the lower clamping rod 103, the upper clamping rod 101 is driven to retract the lower clamping rod 103, so that the clamping rollers 102 clamp the high-voltage wires. The first motor 104 and the second motor 105 are activated to drive the clamping rollers 102 to rotate, so that the equipment can move on the wires. The two high-voltage wires are clamped by the upper clamping rod 101 and the lower clamping rod 103 respectively, so that the equipment is not twisted by the wind during the movement, and the balance of the equipment during the movement is improved.

[0032] like Figures 1-15As shown, a transmission friction rod 114 is horizontally rotatably mounted at the bottom of the conductor groove at the center of the lower clamping rod 103. A bevel gear is fixedly mounted at one end of the transmission friction rod 114. Hollow rotating rods 115 of different diameters are vertically rotatably mounted at the centers of the two lower clamping rods 103. The bottom of the hollow rotating rod 115 is provided with a sliding groove, and a bevel gear is fixedly mounted at the top of the hollow rotating rod 115. The bevel gear on the transmission friction rod 114 meshes with the bevel gear on the hollow rotating rod 115. Arc-shaped rods 117 of different diameters are fixedly mounted at the bottom of the two lower clamping rods 103 respectively. The arc-shaped rods 117 in the two lower clamping rods 103 slide in cooperation with the sliding grooves in the opposite hollow rotating rod 115. The transmission friction rod 114 is used to contact and cooperate with the surface of the high-voltage conductor. When the equipment has finished inspecting one layer of conductors, and it is necessary to inspect the next layer of conductors, the upper clamping rod 101 and the lower clamping rod 103 are released by activating the electric push rod. The clamping of the conductor allows the equipment to tilt and rotate along the axial direction of the conductor held at the bottom by gravity. The contact between the clamping pulley 116 and the conductor reduces the rotational friction between the clamping roller 102 and the conductor, making it easier for the equipment to rotate on the conductor. At the same time, the contact between the bottom transmission friction rod 114 and the conductor causes the transmission friction rod 114 to rotate within the lower clamping rod 103 when the equipment rotates. The transmission friction rod 114 drives the hollow rotating rod 115 to rotate within the bottom lower clamping rod 103. The bottom hollow rotating rod 115 cooperates with the arc-shaped rod 117 within the top lower clamping rod 103, driving the top lower clamping rod 103 to rotate. This causes the clamping openings of the top lower clamping rod 103 and the upper clamping rod 101 to rotate to the tilting direction, allowing the top upper clamping rod 101 and the lower clamping rod 103 to clamp the conductor of the lower layer, enabling the equipment to automatically change layers for maintenance.

[0033] like Figures 1-15As shown, a detection slider 110 is longitudinally slidably mounted on the bottom of the upper clamping rod 101. A compression spring is fixedly installed between the detection slider 110 and the upper clamping rod 101. A three-sided detection rod 111 is laterally rotatably mounted inside the detection slider 110. Multiple metal detection rods 118 are rotatably mounted on the outside of the three-sided detection rod 111. The three-sided detection rods 111 slide and contact the outer surface of the wire to detect cracks on the wire. The metal detection rods 118 are used to detect whether there is exposed wiring inside the crack, which helps to remind staff to replace the wire in time. A transmission gear 112 is laterally rotatably mounted on the bottom of the upper clamping rod 101. A torsion spring is fixedly installed between the transmission gear 112 and the upper clamping rod 101. A lever is fixedly mounted on the transmission gear 112. The lever on the transmission gear 112 contacts and engages with the three-sided detection rod 111. A glue outlet 113 is longitudinally slidably mounted on the bottom of the upper clamping rod 101 for dispensing glue. The outer side of the outlet 113 is provided with gear patterns. The gear patterns on the outlet 113 mesh with the transmission gear 112. A liquid storage tank 119 is fixedly installed on the upper clamping rod 101. The liquid storage tank 119 is connected to the outlet 113 through a pipe. When the equipment moves, the three-sided detection rod 111 contacts the outer surface of the wire. When the three-sided detection rod 111 passes a crack on the wire, the probe on the three-sided detection rod 111 is inserted into the crack. During the movement of the equipment, the three-sided detection rod 111 is driven to rotate inside the detection slider 110. At the same time, the detection slider 110 is retracted into the upper clamping rod 101. When the three-sided detection rod 111 rotates, the other probes contact and engage with the lever on the transmission gear 112, driving the transmission gear 112 to rotate. When the transmission gear 112 rotates, it drives the outlet 113 to extend out from the upper clamping rod 101 to bond the crack on the wire and complete the repair of the wire.

[0034] like Figures 1-15As shown, cleaning brushes 109 are fixedly installed at both ends of the upper clamping rod 101 and the lower clamping rod 103. The cleaning brushes 109 are used to remove adhering substances from the wires, facilitating subsequent repair and inspection. Arc-shaped scrapers 108 are laterally rotatably installed at both ends of the upper clamping rod 101. The arc-shaped scrapers 108 are used to scrape off larger adhering substances from the wires. The outer ring of the arc-shaped scrapers 108 has gear patterns, and the arc-shaped scrapers 108 slide in cooperation with the outer ring of the cleaning brushes 109. A third motor 106 is fixedly installed at both ends of the upper clamping rod 101, and a half-gear is fixedly installed on the third motor 106. Hollow sliders 107 are laterally slidably installed at both ends of the upper clamping rod 101. The hollow slider 107 has gear patterns on its inner side and bottom. The gear patterns on the inner side of the hollow slider 107 mesh with the half gear on the third motor 106, and the gear patterns on the outer side of the hollow slider 107 mesh with the gear patterns on the outer ring of the arc-shaped scraper 108. By starting the third motor 106, the half gear is driven to rotate, and the half gear drives the hollow slider 107 to slide back and forth in the upper clamping rod 101. The hollow slider 107 drives the arc-shaped scraper 108 to slide back and forth in an arc on the upper clamping rod 101 to scrape away foreign objects on the wire. The cleaning brush 109 then removes any remaining attachments on the wire, allowing for smooth maintenance and avoiding the tedious process of manually removing attachments.

[0035] like Figures 1-15 As shown, a connecting mechanism 2 is longitudinally rotatably installed between the lower clamping rods 103. The connecting mechanism 2 includes a telescopic bracket 204, which is rotatably installed between the bottoms of the two lower clamping rods 103 and rotates with the bottoms of the lower clamping rods 103. The telescopic bracket 204 is used to control the telescopic distance between the two lower clamping rods 103, which facilitates the clamping and maintenance of wires with different row spacings.

[0036] like Figures 1-15As shown, the connecting mechanism 2 includes two hollow round rods 203. A limit slider is fixedly installed on the outer ring of each hollow round rod 203. The hollow round rods 203 are longitudinally rotatably mounted on the bottom of two lower clamping rods 103. A positioning hollow rod 201 is longitudinally slidably mounted on the outer ring of each hollow round rod 203. A groove is provided on the inner ring of the positioning hollow rod 201. The limit slider on the hollow round rod 203 slides in cooperation with the groove in the positioning hollow rod 201. Grooves are provided on both sides of the positioning hollow rod 201. A limit plate 202 is longitudinally slidably installed in the grooves on both sides of the positioning hollow rod 201. The limit plate 202 contacts the outer wall of the rectangular rod at the bottom of the lower clamping rod 103. The limit plate 202 is used to limit the rotation of the positioning hollow rod 201 and prevent it from rotating when the equipment is switching or being repaired. 2. The device can rotate freely. A wire guide plate 206 is fixedly installed on the outside of the positioning hollow rod 201. A wire winding disc 205 is installed horizontally inside the wire guide plate 206. The wire winding disc 205 is used to hold the wire bundle and provide counterweight for the device, so that the device can tilt in the direction of the wire winding disc 205, ensuring that the device can smoothly switch to repair wires and assist the staff in installing new wires. When the device tilts and rotates on the wires to repair the next layer of wires, the positioning hollow rod 201 maintains its original angle and rotates with the device through the cooperation of the limiting plate 202 and the bottom clamping rod 103. After the device finishes changing layers, the limiting plate 202 slides downward in the positioning hollow rod 201 by gravity and cooperates with the rectangular rod on the bottom clamping rod 103 again.

[0037] Working principle: When inspecting high-voltage conductors, the electric push rod on the lower clamping rod 103 is activated to drive the upper clamping rod 101 to slide on the lower clamping rod 103, so that the upper clamping rod 101 and the lower clamping rod 103 cooperate to clamp the conductor. Then, the first motor 104 and the second motor 105 are activated to drive the clamping roller 102 to rotate, so that the equipment moves on the conductor. At the same time, the third motor 106 is activated to drive the arc-shaped scraper 108 to slide back and forth at both ends of the upper clamping rod 101 to remove foreign objects on the conductor. The cleaning brush 109 removes the remaining foreign objects. Then, the clamping roller 102 bends the conductor slightly to make the cracks on the conductor easier to detect. Then, the three-sided detection rod 111 detects the cracks on the conductor. At the same time, the metal detection rod 118 detects whether there is any conductor leaking out of the crack. Then, the three-sided detection rod 111 drives the transmission gear 112 to rotate, and controls the glue outlet 113 to extend from the upper clamping rod 101 to glue the crack.

[0038] When it is necessary to replace the wire, the wire bundle is placed in the wire reel 205 and the other end of the wire bundle is passed to the connection point by the equipment moving on the wire. The other end is then connected by the staff to complete the wire replacement.

[0039] When the equipment finishes inspecting one layer of wires, the electric push rod on the top lower clamping rod 103 is activated, causing the top upper clamping rod 101 and the lower clamping rod 103 to release their clamping of the wires. This allows the equipment to tilt and rotate on the bottom wires, enabling the top upper clamping rod 101 and the lower clamping rod 103 to clamp the next layer of wires for a new round of inspection.
