Description

Technical Field

[0001] This invention relates to the field of circuit testing equipment technology, specifically to a power transmission line interruption fault detection device. Background Technology

[0002] The normal functioning of modern society, much like the life activities of the human body, highly depends on a continuous supply of energy. The crisscrossing, thousand-mile-long power transmission lines are the "main arteries" carrying this energy, efficiently and reliably transmitting the powerful electrical energy generated by power plants to cities, villages, and every end-user. The safe and stable operation of these transmission lines is directly related to the national economy, people's livelihoods, industrial production, economic development, and even the stability of social order. However, these transmission lines, exposed to complex natural and ever-changing social environments, are extremely vulnerable, susceptible to various factors such as lightning strikes, strong winds, snow, bird damage, tree growth, external damage, and the aging of the equipment itself. All of these can lead to line faults. Among them, one of the most typical and dangerous faults is the current interruption fault. It usually refers to the abnormal interruption of the current path between the phase line and the ground or between the phase line due to the breakage of the conductor or the damage to the insulation. Once a current interruption fault occurs, a huge short-circuit current will be generated in the system instantly, triggering a series of chain reactions. The high temperature of the arc at the fault point may melt the conductor and damage the tower. Electrical equipment may be damaged due to the current and voltage that are far beyond the design standards. More importantly, the fault will cause the grid voltage to drop sharply and the frequency to fluctuate, which will destroy the stability of the entire power system and may cause large-scale power outages, resulting in incalculable economic losses and social impacts.

[0003] Existing technologies often fail to detect the transmission lines before testing due to dust, rain, snow, and other impurities on the surface, leading to inaccurate results. Furthermore, traditional equipment is typically tested in an exposed manner without protective measures, making it susceptible to short circuits and damage from rain and snow, which increases costs and safety hazards. Summary of the Invention

[0004] To solve the above technical problems, the present invention is implemented through the following technical solution: a power transmission line interruption fault detection device, comprising a first connecting ring, a cleaning device fixedly connected to the inner wall of the first connecting ring, a first bracket evenly fixedly connected to the side of the first connecting ring, a first connecting plate fixedly connected to the top of the first bracket, a driving assembly fixedly connected to the top of the first connecting plate, second connecting rings fixedly connected to both sides of the first connecting plate, a clamping assembly fixedly connected to the side of the second connecting ring away from the first connecting plate, a fixing block fixedly connected to the side of the second connecting ring, a first rotating block rotatably connected to the side of the fixing block away from the second connecting ring, a first motor fixedly connected to the side of the first rotating block, a drive shaft of the first motor passing through the first rotating block and fixedly connected to a threaded rod, a sliding block sleeved and threadedly connected to the threaded rod, one side of the sliding block rotatably connected to the clamping assembly, and an adjustable protective device evenly fixedly connected to the side of the second connecting ring.

[0005] Preferably, the clamping assembly includes a first rotating ring, with first connecting blocks evenly fixedly connected to the side of the first rotating ring, and a second rotating ring fixedly connected to the side of the first connecting block away from the first rotating ring. A rotating frame is rotatably connected to the portion of the side of the first rotating ring located on the side of the first connecting block. One end of the rotating frame has a rotating opening, and a clamping cable guide wheel is rotatably connected to the inner wall of the rotating opening. A second rotating block is rotatably connected to the end of the rotating frame away from the rotating opening. A first connecting rod is fixedly connected to the side of the first rotating ring, and the side of the first rotating ring is rotatably connected to the second connecting ring. The side of the second rotating block is fixedly connected to the second connecting ring, and the side of the first connecting rod is rotatably connected to the sliding block. After the first and second connecting rings are fitted onto the transmission line to be tested, the first motor is started, and its drive shaft drives the threaded rod to rotate, causing the sliding block to move linearly along the threaded rod. Because the sliding block is rotatably connected to the first connecting rod of the clamping assembly, and the first connecting rod is fixed to the first rotating ring, the movement of the sliding block will cause the first rotating ring and the second rotating ring to rotate relative to each other. At the same time, the first rotating block and the first motor rotate synchronously, adjusting the opening and closing degree of the clamping assembly, so as to achieve stable clamping of transmission lines of different wire diameters and provide a stable foundation for testing.

[0006] Preferably, the cleaning device includes an annular slide rail, with a first electric slider slidably connected to the inner wall of the annular slide rail. Detectors are fixedly connected to both sides of the first electric slider. A second connecting plate is fixedly connected to the side of the first electric slider away from the annular slide rail. The fixed ends of a first and second electric telescopic rods are respectively fixedly connected to the side of the second connecting plate away from the first electric slider. A first fixing plate is fixedly connected to the movable end of the first electric telescopic rod. Cleaning brushes are evenly fixedly connected to the side of the first fixing plate away from the first electric telescopic rod. A second fixing plate is fixedly connected to the movable end of the second electric telescopic rod. A heater is fixedly connected to the side of the second fixing plate away from the second electric telescopic rod. The sides of the two fixed plates, located on both sides of the heater, are fixedly connected to second brackets. A hot melt adhesive tape roll is rotatably connected to the inner wall of the second bracket. The annular slide rail is fixedly connected to the inner wall of the first connecting ring. If dust, dirt, or frost adheres to the circuit surface, the first electric telescopic rod is activated. Its movable end pushes the first fixed plate and cleaning brush closer to the circuit. As the first electric slider moves, the cleaning brush thoroughly cleans impurities, eliminating detection interference. If there are marks on the circuit surface requiring repair, the second electric telescopic rod is activated, pushing the second fixed plate and heater closer. The heater heats the hot melt adhesive tape, activating its adhesiveness. The hot melt adhesive tape roll rotates with the second bracket. As the first electric slider moves around the circuit, the hot melt adhesive tape is evenly applied to the repair area, completing the repair.

[0007] Preferably, the drive assembly includes a third fixed plate, with the movable end of a third electric telescopic rod fixedly connected to the top of the third fixed plate, and a third bracket fixedly connected to the bottom of the third fixed plate. A drive friction wheel is rotatably connected to the inner wall of the third bracket, and a rotating rod is rotatably connected through and to the side of the third bracket. The rotating rod is fixedly connected to the drive friction wheel, and a driven gear is sleeved and fixedly connected to the portion of the rotating rod located on one side of the third bracket. A drive gear meshes with the side of the driven gear, and a drive shaft of a second motor is fixedly connected to the side of the drive gear. The second motor is fixedly connected to the top of the third fixed plate, and the fixed end of the third electric telescopic rod is fixedly connected to a first connecting plate. At the top, the movable end of the third electric telescopic rod passes through the top of the first connecting plate. Two sets of the third electric telescopic rod are provided and distributed on both sides of the first connecting ring. When it is necessary to adjust the position of the device on the transmission line, the third electric telescopic rod is activated, and its movable end extends, driving the third fixed plate, the third bracket, and the driving friction wheel to move down until the driving friction wheel is in close contact with the line surface. The second motor is then activated, and its drive shaft drives the active gear to rotate. Through meshing transmission, the driven gear drives the rotating rod and the driving friction wheel to rotate synchronously. Under the driving force of the driving friction wheel and the guiding action of the clamping cable wheel, the device moves along the line. The two sets of symmetrical drive devices ensure stability and balance during the movement.

[0008] Preferably, the adjustable protective device includes a third connecting plate, with a fixed end of a fourth electric telescopic rod fixedly connected to the top of the third connecting plate. An arc-shaped protective cover is fixedly connected to the movable end of the fourth electric telescopic rod. A first sliding groove is formed on the side of the arc-shaped protective cover, and second sliding grooves are formed on both sides of the inner wall of the first sliding groove. A second electric slider is slidably connected to the inner wall of the second sliding groove, and a telescopic protective cover is fixedly connected to the side of the second electric slider. The third connecting plate is fixedly connected to the side of a second connecting ring. Multiple sets of the third connecting plate are arranged in a triangular symmetrical distribution on the side of the second connecting ring. When the equipment is working normally, the telescopic protective cover... The protective cover extends fully from the first sliding groove of the arc-shaped protective cover. Driven by the fourth electric telescopic rod, it and the arc-shaped protective cover together wrap around the device, forming a tight protective structure. This prevents damage to the internal detection components from heavy rain, blizzards, and strong winds, ensuring continuous operation in severe weather. When encountering obstacles such as tree branches, the arc-shaped protective cover is blocked. The second electric slider is activated and slides along the second sliding groove into the first sliding groove, causing the telescopic protective cover to retract into the first sliding groove. At the same time, the fourth electric telescopic rod retracts, moving the arc-shaped protective cover closer to the line and lowering its overall height to avoid obstacles. After passing the obstacle, the second electric slider causes the telescopic protective cover to extend again, restoring the protective state.

[0009] This invention provides a device for detecting power transmission line interruption faults. It has the following advantages: 1. The power transmission line interruption fault detection device starts by activating a first motor to drive a threaded rod to rotate. The sliding block moves linearly along the threaded rod, which in turn causes the first and second rotating rings to rotate relative to each other. In conjunction with the synchronous adjustment of the first rotating block, the opening and closing degree of the clamping component can be flexibly adjusted, thereby enabling the stable clamping of power transmission lines of different wire diameters. This eliminates the need for frequent changes of special clamping tools, greatly improving the equipment's versatility. During high-altitude operations, the stable clamping force can prevent the equipment from shifting or falling off due to wind or line swaying, ensuring that the detection component is tightly attached to the line surface, improving detection accuracy, reducing detection errors caused by unstable clamping, improving overall detection efficiency, and preventing slippage that could cause safety hazards.

[0010] The fault detection device for this power transmission line uses a first electric slider to drive a detector to scan the circumference of the line. If dust, dirt, or frost is found on the surface, these impurities can easily cause the detector to misjudge line damage. The first electric telescopic rod can be activated to push a cleaning brush to adhere to the line. The brush is cleaned from all angles as the first electric slider moves in a circular motion, ensuring accurate detection data. If marks are detected on the line surface, such as minor scratches or insulation damage, a heater is activated to heat the hot melt adhesive tape. Then, the second electric telescopic rod is activated to push the hot melt adhesive tape, which, after heating, becomes sticky and adheres to the surface of the power transmission line that needs repair. The tape is evenly applied and repaired as the slider moves, eliminating the need for manual climbing for repairs. This reduces the frequency of high-altitude operations and significantly improves practicality and work efficiency.

[0011] The fault detection device for this transmission line uses a third electric telescopic rod to bring the driving friction wheel into contact with the line. The second motor drives the friction wheel to rotate through gear transmission. Combined with the guiding action of the clamping wire wheel, it can drive the equipment to move smoothly along the line. The two sets of driving devices are symmetrically distributed on both sides of the first connecting ring, avoiding the tilting or jamming of the equipment caused by unilateral driving. This allows for flexible adjustment of the detection position without the need for manual rope pulling for positioning. The movement process is also stable. Especially in windy conditions in the field, symmetrical driving can balance the force on the equipment, avoid affecting the detection effect, and improve the comprehensiveness and convenience of the detection.

[0012] This power transmission line fault detection device, through its telescopic protection and dynamic obstacle avoidance, copes with complex outdoor environments. During normal operation, the telescopic protective cover extends fully under the action of the second electric slider, forming a sealed space with the arc-shaped protective cover. This blocks severe weather conditions such as heavy rain, blizzards, and strong winds, preventing rainwater from seeping into the detection components and causing short circuits, or snow from covering the detector and affecting data acquisition. This ensures continuous operation and reduces the probability of equipment damage. When encountering obstacles such as tree branches or tower attachments, the second electric slider retracts the telescopic protective cover into the arc-shaped protective cover, and the fourth electric telescopic rod shortens, lowering the overall height of the protective cover and smoothly avoiding obstacles. No manual obstacle removal is required, and the device quickly returns to protective mode after passing through. This solves the problems of traditional detection equipment stopping in severe weather and getting stuck when encountering obstacles, significantly improving the equipment's adaptability to complex outdoor environments, reducing detection interruptions caused by environmental factors, and ensuring the continuity and efficiency of power transmission line inspection work.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] For the first embodiment, please refer to... Figures 1-4This invention provides a technical solution: a power transmission line interruption fault detection device, comprising a first connecting ring 1, a cleaning device 2 fixedly connected to the inner wall of the first connecting ring 1, a first bracket 3 evenly fixedly connected to the side of the first connecting ring 1, a first connecting plate 4 fixedly connected to the top of the first bracket 3, a driving assembly 5 fixedly connected to the top of the first connecting plate 4, second connecting rings 6 fixedly connected to both sides of the first connecting plate 4, a clamping assembly 7 fixedly connected to the side of the second connecting ring 6 away from the first connecting plate 4, a fixing block 10 fixedly connected to the side of the second connecting ring 6, a first rotating block 11 rotatably connected to the side of the fixing block 10 away from the second connecting ring 6, a first motor 12 fixedly connected to the side of the first rotating block 11, a threaded rod 13 fixedly connected to the drive shaft of the first motor 12 passing through the first rotating block 11, a sliding block 8 sleeved on and threadedly connected to the threaded rod 13, and one side of the sliding block 8 connected to the clamping assembly. The component 7 is rotatably connected. Adjustable protective devices 9 are evenly fixedly connected to the side of the second connecting ring 6. The clamping assembly 7 includes a first rotating ring 71. A first connecting block 72 is evenly fixedly connected to the side of the first rotating ring 71. A second rotating ring 73 is fixedly connected to the side of the first connecting block 72 away from the first rotating ring 71. A rotating frame 74 is rotatably connected to the part of the side of the first rotating ring 71 located on the side of the first connecting block 72. A rotating opening 75 is opened at one end of the rotating frame 74. A clamping cable wheel 76 is rotatably connected to the inner wall of the rotating opening 75. A second rotating block 77 is rotatably connected to the end of the rotating frame 74 away from the rotating opening 75. A first connecting rod 78 is fixedly connected to the side of the first rotating ring 71. The side of the first rotating ring 71 is rotatably connected to the second connecting ring 6. The side of the second rotating block 77 is fixedly connected to the second connecting ring 6. The side of the first connecting rod 78 is rotatably connected to the sliding block 8.

[0017] In use, the first connecting ring 1 and the second connecting ring 6 are fitted onto the outside of the transmission line to be tested, and then the transmission line is clamped and fixed. The first motor 12 is started, and the drive shaft of the first motor 12 rotates, driving the threaded rod 13 to rotate. The rotation of the threaded rod 13 causes the sliding block 8 to move linearly along the threaded rod 13. Since the sliding block 8 is rotatably connected to the first connecting rod 78 in the clamping assembly 7, and the first connecting rod 78 is fixedly connected to the first rotating ring 71, the movement of the sliding block 8 will cause the first rotating ring 71 and the second rotating ring 73 to rotate relative to each other. At the same time, the first rotating block 11 and the first motor 12 rotate synchronously to adjust the opening and closing degree of the clamping assembly 7, thereby achieving stable clamping of transmission lines of different wire diameters. Then, the transmission line is tested, thereby improving the adaptability of the device and the efficiency of the test.

[0018] For the second embodiment, please refer to... Figures 1-5Based on the first embodiment, the present invention provides a technical solution: the cleaning device 2 includes an annular slide rail 21, a first electric slider 22 is slidably connected to the inner wall of the annular slide rail 21, detectors 23 are fixedly connected to both sides of the first electric slider 22, a second connecting plate 24 is fixedly connected to the side of the first electric slider 22 away from the annular slide rail 21, and the fixed end of the first electric telescopic rod 25 and the fixed end of the second electric telescopic rod 26 are respectively fixedly connected to the side of the second connecting plate 24 away from the first electric slider 22, and the movable end of the first electric telescopic rod 25 is fixedly connected to... A first fixing plate 27 is attached, and a cleaning brush 28 is evenly fixedly connected to the side of the first fixing plate 27 away from the first electric telescopic rod 25. A second fixing plate 29 is fixedly connected to the movable end of the second electric telescopic rod 26. A heater 210 is fixedly connected to the side of the second fixing plate 29 away from the second electric telescopic rod 26. A second bracket 211 is fixedly connected to the side of the second fixing plate 29 on both sides of the heater 210. A hot melt adhesive tape roll 212 is rotatably connected to the inner wall of the second bracket 211. An annular slide rail 21 is fixedly connected to the inner wall of the first connecting ring 1.

[0019] In use, after the clamping assembly 7 clamps the transmission line, the surface of the transmission line will be covered with dust, dirt, and possibly frost due to prolonged exposure to wind, dust, rain, and snow at high altitudes. These impurities can affect the accuracy of the detection. At this time, the first electric slider 22 is activated. The first electric slider 22 moves in a circular motion along the annular slide rail 21, driving the detectors 23 on both sides to detect the transmission line. Depending on the detected condition of the line surface, the first electric telescopic rod 25 or the second electric telescopic rod 26 is activated. If the line surface is mainly covered with dust, dirt, and frost, the first electric telescopic rod 25 is activated. The movable end of the first electric telescopic rod 25 extends, pushing the first fixing plate 27 closer to the transmission line. The cleaning brush 28 contacts the surface of the power line. As the first electric slider 22 continues to move, the cleaning brush 28 thoroughly cleans the surface of the power line, removing dust and dirt. If there are marks on the surface of the power line that need to be repaired, the second electric telescopic rod 26 is activated. The movable end of the second electric telescopic rod 26 extends and pushes the second fixed plate 29 closer to the power line, so that the heater 210 heats the hot melt adhesive tape to make it sticky. The hot melt adhesive tape adheres to the area of ​​the power line that needs to be repaired. As the first electric slider 22 moves around the power line, the hot melt adhesive tape roll 212 rotates on the second bracket 211, evenly pasting the hot melt adhesive tape onto the area of ​​the power line that needs to be repaired, thus completing the repair of the power line and improving the functionality and practicality of the device.

[0020] Third embodiment, please refer to Figures 1-6Based on the second embodiment, the present invention provides a technical solution: the drive assembly 5 includes a third fixed plate 51, the top of the third fixed plate 51 is fixedly connected to the movable end of the third electric telescopic rod 52, the bottom of the third fixed plate 51 is fixedly connected to a third bracket 53, the inner wall of the third bracket 53 is rotatably connected to a drive friction wheel 54, the side of the third bracket 53 is through and rotatably connected to a rotating rod 55, the rotating rod 55 is fixedly connected to the drive friction wheel 54, the part of the rotating rod 55 located on one side of the third bracket 53 is sleeved and fixedly connected to a driven gear 56, the side of the driven gear 56 is meshed with a driving gear 57, the side of the driving gear 57 is fixedly connected to the drive shaft of a second motor 58, the second motor 58 is fixedly connected to the top of the third fixed plate 51, the fixed end of the third electric telescopic rod 52 is fixedly connected to the top of the first connecting plate 4, the movable end of the third electric telescopic rod 52 passes through the top of the first connecting plate 4, and two sets of the third electric telescopic rod 52 are provided and distributed on both sides of the first connecting ring 1 respectively.

[0021] In use, when the position of the device on the power transmission line needs to be adjusted for more comprehensive testing or to reach a specific testing point, the third electric telescopic rod 52 is activated. The movable end of the third electric telescopic rod 52 extends, causing the third fixed plate 51 to move downwards, thereby bringing the third bracket 53 and the drive friction wheel 54 closer to the power transmission line. After the drive friction wheel 54 is in close contact with the surface of the power transmission line, the second motor 58 is activated. The drive shaft of the second motor 58 rotates, driving the drive gear 57 to rotate. The drive gear 57 meshes with the driven gear 56, causing the driven gear 56 to drive the rotating rod 55 and the drive friction wheel 54 to rotate synchronously. Under the rotation of the drive friction wheel 54 and the guidance of the clamping wire wheel 76, the entire device moves along the power transmission line. The drive assembly 5 is provided in two sets, located on both sides of the first connecting ring 1, thereby ensuring the stability and balance of the device during movement. This allows for flexible adjustment of the device's position on the power transmission line for more comprehensive testing or to accurately reach a specific testing point, further improving the ease of use and comprehensiveness of testing.

[0022] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the adjustable protective device 9 includes a third connecting plate 91, the top of the third connecting plate 91 is fixedly connected to the fixed end of the fourth electric telescopic rod 92, the movable end of the fourth electric telescopic rod 92 is fixedly connected to the arc-shaped protective cover 93, the side of the arc-shaped protective cover 93 is provided with a first sliding groove 94, the inner wall of the first sliding groove 94 is provided with a second sliding groove 95 on both sides, the inner wall of the second sliding groove 95 is slidably connected to a second electric slider 96, the side of the second electric slider 96 is fixedly connected to a telescopic protective cover 97, the third connecting plate 91 is fixedly connected to the side of the second connecting ring 6, and multiple sets of the third connecting plate 91 are provided and distributed in a triangular symmetrical manner on the side of the second connecting ring 6.

[0023] In use, when the equipment is working normally, the telescopic protective cover 97 extends fully from the first sliding groove 94 of the arc-shaped protective cover 93. Driven by the fourth electric telescopic rod 92, it encloses the entire device inside the arc-shaped protective cover 93, thus avoiding severe weather such as heavy rain, heavy snow, or strong winds. Together with the arc-shaped protective cover 93, it forms a more robust protective structure, effectively blocking wind, rain, snow, etc., from damaging the internal detection components of the device, ensuring that the detection work can be carried out continuously and stably even in harsh environments. When encountering obstacles of height such as tree branches, the arc-shaped protective cover 93 will be blocked, thereby activating the second electric slider 96. The second electric slider 96 slides along the second sliding groove 95 into the interior of the first sliding groove 94. The telescopic protective cover 97 retracts inward into the first sliding groove 94. Then, the fourth electric telescopic rod 92 is activated, and its movable end retracts, causing the arc-shaped protective cover 93 to move closer to the power transmission line. This lowers the overall height of the arc-shaped protective cover 93 and the telescopic protective cover 97, allowing it to smoothly avoid obstacles such as tree branches. After passing the obstacle, the second electric slider 96 slides along the second sliding groove 95 towards the outlet of the first sliding groove 94, causing the telescopic protective cover 97 to extend again and restore the tight protection of the device. This ensures the normal operation of the device in severe weather and allows for flexible adjustment when encountering obstacles, improving the device's adaptability and practicality to different environments.

[0024] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
