[0002] A fault detection and location device for transmission and distribution lines is a professional device used to detect and locate faults in transmission and distribution lines. It collects electrical signals of the line through devices such as sensors, uses advanced algorithms to judge faults, combines location technologies to determine the location of the fault point, improves the efficiency and accuracy of fault detection, and ensures the reliability of power supply.

[0003] In the fault detection of transmission and distribution lines, traditional detection methods often have many problems. On the one hand, detection personnel usually need to climb the cable for detection, which not only has high operation difficulty and low efficiency, but also has great safety risks. It is not easy for pedestrians to climb the cable, which makes the progress of fault detection work slow and increases the detection cost at the same time. Summary of the Invention

[0005] The suspension device includes a mounting plate, the top of the mounting plate is fixedly connected with a fixing frame, the outside of the fixing frame is fixedly connected with a driving motor, the output end of the driving motor is fixedly connected with a guiding wheel, and a locking component is slidably connected to the inner wall of the mounting plate. The suspension device is limited by the locking component to prevent it from separating from the cable during movement.

[0006] Preferably, the bottom of the housing is fixedly connected to the top of the support plate. The output end of the servo motor is fixedly connected to the outer side of the driving wheel through a pulley group. The outer side of the driving wheel is in rolling connection with the outer wall of the accompanying ring body. The side wall of the accompanying ring body is in rolling connection with the outer wall of the boosting wheel. The open design of the semi-circular rail positioning ring and the accompanying ring body also enables the cable to pass through the middle of the accompanying ring body more quickly and conveniently.

[0007] Preferably, both sides of the housing are fixedly connected to the outer sides of the mounting plates. The inner sides of the fixing frames are rotationally connected to both sides of the guiding wheels. The top of the locking assembly is slidably connected to the inner wall of the fixing frame.

[0009] Preferably, the top of the mounting frame is fixedly connected to both sides of the inner wall of the housing. The top end of the compression spring is fixedly connected to the bottom of the mounting frame. When the swaying amplitude is relatively large, the swing plate will contact the buffer block.

[0010] Preferably, the locking assembly includes a connecting plate. A sliding block is fixedly connected to the top of the connecting plate. A sliding plate is slidably connected to the inner side of the sliding block. A pressing wheel is rotationally connected to the top of the sliding plate. A elastic piece is fixedly connected to the bottom of the sliding plate. A limiting member is fixedly connected to the bottom of the connecting plate. The elastic action of the elastic piece enables the pressing wheel to adapt to cables of different sizes.

[0011] Preferably, the outer wall of the sliding block is slidably connected to the inner wall of the mounting plate. The bottom of the elastic piece is fixedly connected to the inner side of the sliding block. The top of the limiting member is fixedly connected to the bottom of the mounting plate. The top of the sliding block is slidably connected to the inner wall of the fixing frame. The sliding plate moves upward together with the sliding block under the push of the elastic piece, so that the surface of the pressing wheel contacts the cable, further enhancing the fixing effect of the device on the cable.

The top ends of the tension spring and the limiting rod are both fixedly connected to the bottom of the mounting plate. By rotating the rotating cylinder in the limiting member, the clamping block is disengaged from the clamping groove in the arc-shaped limiting plate. At this time, the elastic force of the tension spring is released, and the fixed cylinder is driven to slide upward along the surface of the limiting rod.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention hangs the whole device on the cable through the suspension device, limits the suspension device through the locking component, and then drives the guide wheel to rotate through the driving motor, so that the whole device can move along the surface of the cable, greatly improving the detection efficiency, solving the problem that it is not easy for pedestrians to climb the cable, thereby reducing the detection cost and risk.

[0016] 2. By setting the locking component, the present invention forms a "mouth" - shaped connection between the fixed frame, the sliding block and the mounting plate. This "mouth" - shaped connection can effectively prevent the cable from detaching from the device. Even when the device is subjected to external interference or the cable shakes, the firm connection between the device and the cable can be maintained, reducing the possibility of accidental detachment of the device and reducing the potential harm to surrounding personnel and facilities.

[0017] 3. The present invention realizes the locking of the locking component by rotating the rotating cylinder, reducing the working difficulty and operation time of the operator, improving the use efficiency of the device. Through the quick - limiting function, the time used to fix the device on the cable is reduced, enabling the detection personnel to deploy the device faster and start the fault - detection work, improving the overall detection efficiency and enhancing the emergency response ability of the device.

[0018] 4. By setting the pressing wheel, the sliding plate moves upward together with the sliding block under the push of the elastic piece, so that the surface of the pressing wheel contacts the cable, further enhancing the fixing effect of the device on the cable. The close contact between the pressing wheel and the cable increases the friction force between the device and the cable, preventing the device from slipping during the movement process and ensuring that the device can move stably along the surface of the cable.

[0019] 5. The present invention is provided with elastic pieces, and the elastic effect of the elastic pieces enables the pressing wheel to adapt to cables of different sizes. When encountering a thicker cable, the elastic pieces will be compressed to ensure that the pressing wheel can still closely fit the surface of the cable; for a thinner cable, the elastic force of the elastic pieces can keep the pressing wheel under sufficient pressure to ensure the stability of the device. This adaptability improves the versatility of the device, enabling it to perform fault detection and location on power transmission and distribution lines of different specifications.

[0020] 6. The present invention is provided with a detection device. The servo motor drives the driving wheels on both sides of the housing to rotate simultaneously through a pulley group, enabling the accompanying ring body to perform a circular motion along the surface of the semi-circular rail positioning ring. The boosting wheel can reduce the frictional resistance during the operation of the accompanying ring body. This motion mode enables the detection probe installed on the accompanying ring body to detect the power transmission and distribution line at different angles and positions. Meanwhile, by adjusting the length of the telescopic rod, the detection probe can be more accurately aligned with the fault point, improving the detection accuracy and reliability and reducing the possibility of missed fault detection.

[0021] 7. The present invention is provided with a semi-circular rail positioning ring and an accompanying ring body. The open design of the semi-circular rail positioning ring and the accompanying ring body enables the cable to pass through the middle of the accompanying ring body more quickly and conveniently. The open design of the semi-circular rail positioning ring and the accompanying ring body has great flexibility. This enables the device to adapt to different cable layouts and installation methods. Whether it is an overhead line or an underground cable, the device can be easily installed on the cable for detection. This open design also facilitates the installation and disassembly of the device, improving the operability of the device.

[0022] 8. The present invention is provided with an anti-shake component. When the device shakes due to external interference, the swing plate on the outside of the mounting frame will swing under the action of inertia. The counterweight block at the bottom plays a role in stabilizing the center of gravity, increasing the stability and inertia of the swing, which helps to improve the adaptability of the device to external interference and enables the device to maintain a relatively stable operating state under different external conditions.

[0023] 9. The present invention is provided with a buffer block. When the shaking amplitude is relatively large, the swing plate will contact the buffer block. The buffer block slides on the arc-shaped guide rail, forcing the compression spring to be compressed. The arc-shaped guide rail provides a guiding function for the movement of the buffer block. The movement of the buffer block converts the shaking energy into frictional force and elastic potential energy, thereby playing a buffering role, reducing the shaking amplitude of the device and reducing the safety risk.

The whole device is hung on the cable through the suspension device 3. At this time, the suspension device 3 is limited by the locking assembly 35 to prevent it from detaching from the cable during the movement. Subsequently, the driving motor 33 drives the guiding wheel 34 to rotate, so that the whole device can move along the surface of the cable, greatly improving the detection efficiency, solving the problem that it is not easy for pedestrians to climb the cable, thereby reducing the detection cost and risk. When detecting through the detection device 2 on the top of the support plate 1, the servo motor 24 drives the driving wheels 25 on both sides of the housing 21 to rotate simultaneously through the pulley group, so that the accompanying ring body 23 can make a circular motion along the surface of the semi-circular rail positioning ring 22. The boosting wheel 29 can reduce the frictional resistance when the accompanying ring body 23 runs. This movement mode enables the detection probe 28 installed on the accompanying ring body 23 to detect the transmission and distribution lines at different angles and positions. At the same time, by adjusting the length of the telescopic rod 27, the detection probe 28 can be more accurately aligned with the fault point, improving the detection accuracy and reliability, and reducing the possibility of missed fault detection;

[0039] Among them, the open design of the semi-circular rail positioning ring 22 and the accompanying ring body 23 also enables the cable to pass through the middle of the accompanying ring body 23 more quickly and conveniently. The open design of the semi-circular rail positioning ring 22 and the accompanying ring body 23 has great flexibility. The cable can pass through the middle of the accompanying ring body 23 more quickly and conveniently, which enables the device to adapt to different cable layouts and installation methods. Whether it is an overhead line or an underground cable, the device can be easily installed on the cable for detection. This open design also facilitates the installation and disassembly of the device and improves the operability of the device.

[0040] The anti-vibration component 26 includes a mounting frame 261. A swing plate 262 is rotatably connected to the outside of the mounting frame 261. A counterweight 263 is fixedly connected to the bottom of the swing plate 262. Arc-shaped guide rails 264 are fixedly connected to both sides of the mounting frame 261. A buffer block 265 is slidably connected to the outer wall of the arc-shaped guide rail 264. A compression spring 266 is fixedly connected to the top of the buffer block 265. The top of the mounting frame 261 is fixedly connected to both sides of the inner wall of the housing 21. The top end of the compression spring 266 is fixedly connected to the bottom of the mounting frame 261. When the anti-vibration component 26 is in use, when the device is shaken due to external interference, the swing plate 262 outside the mounting frame 261 will swing under the action of inertia. The counterweight 263 at the bottom plays a role in stabilizing the center of gravity, increasing the stability and inertia of the swing, which helps to improve the adaptability of the device to external interference and enables the device to maintain a relatively stable operating state under different external conditions;

[0041] When the shaking amplitude is relatively large, the swing plate 262 will contact the buffer block 265. The buffer block 265 slides on the arc-shaped guide rail 264, forcing the compression spring 266 to be compressed. The arc-shaped guide rail 264 provides a guiding function for the movement of the buffer block 265. The movement of the buffer block 265 converts the shaking energy into frictional force and elastic potential energy, thus playing a buffering role, reducing the shaking amplitude of the device and reducing safety risks.

[0042] The locking assembly 35 includes a connecting plate 351. A sliding block 352 is fixedly connected to the top of the connecting plate 351. A sliding plate 353 is slidably connected to the inside of the sliding block 352. A pressing wheel 354 is rotatably connected to the top of the sliding plate 353. A elastic piece 355 is fixedly connected to the bottom of the sliding plate 353. A limiting member 356 is fixedly connected to the bottom of the connecting plate 351. The outer wall of the sliding block 352 is slidably connected to the inner wall of the mounting plate 31. The bottom of the elastic piece 355 is fixedly connected to the inside of the sliding block 352. The top of the limiting member 356 is fixedly connected to the bottom of the mounting plate 31. The top of the sliding block 352 is slidably connected to the inner wall of the fixing frame 32. The limiting member 356 includes a fixing cylinder 561. A rotating cylinder 564 is rotatably connected to the outside of the fixing cylinder 561. A clamping block 565 is fixedly connected to the inside of the rotating cylinder 564. A tension spring 563 is fixedly connected to the top of the fixing cylinder 561. A limiting rod 562 is slidably connected to the center of the fixing cylinder 561. An arc-shaped limiting plate 566 is fixedly connected to the bottom of the limiting rod 562. The outside of the fixing cylinder 561 is fixedly connected to the inside of the connecting plate 351. The outside of the clamping block 565 is clamped with the inside of the arc-shaped limiting plate 566 through a card slot 567, and the card slot 567 is opened in the wall of the arc-shaped limiting plate 566. The top ends of the tension spring 563 and the limiting rod 562 are both fixedly connected to the bottom of the mounting plate 31. When the locking assembly 35 is in use, by rotating the rotating cylinder 564 in the limiting member 356, the clamping block 565 is disengaged from the card slot 567 in the arc-shaped limiting plate 566. At this time, the elastic force of the tension spring 563 is released, and it drives the fixing cylinder 561 to slide upward along the surface of the limiting rod 562, and at the same time drives the connecting plate 351 to move upward. At this time, the connecting plate 351 pushes the sliding block 352 upward, so that a "square" - shaped connection is formed between the fixing frame 32, the sliding block 352 and the mounting plate 31. This "square" - shaped connection can effectively prevent the cable from detaching from the device. Even when the device is subject to external interference or the cable shakes, the firm connection between the device and the cable can be maintained, reducing the possibility of the device accidentally falling off and reducing the potential harm to the surrounding personnel and facilities; The operation of the locking assembly 35 is simple. Just rotating the rotating cylinder 564 can achieve locking. It reduces the working difficulty and operation time of the operator, improves the use efficiency of the device. Through the quick limiting function, the time used to fix the device on the cable is reduced. It enables the detection personnel to deploy the device faster and start the fault detection work, improving the overall detection efficiency and enhancing the emergency response ability of the device;

[0043] At the same time, the sliding plate 353 moves upward together with the sliding block 352 under the push of the elastic piece 355, so that the surface of the pressing wheel 354 contacts the cable, further enhancing the fixing effect of the device on the cable. The close contact between the pressing wheel 354 and the cable increases the friction between the device and the cable, preventing the device from slipping during the moving process and ensuring that the device can move stably along the surface of the cable;

[0044] Among them, the elastic effect of the elastic piece 355 enables the pressing wheel 354 to adapt to cables of different sizes. When encountering a thicker cable, the elastic piece 355 will be compressed to ensure that the pressing wheel 354 can still closely fit the surface of the cable; for a thinner cable, the elastic force of the elastic piece 355 can make the pressing wheel 354 maintain sufficient pressure to ensure the stability of the device. This adaptability improves the versatility of the device, enabling it to perform fault detection and location on power transmission and distribution lines of different specifications.

[0045] Working principle:

[0046] During use, the entire device is hung on the cable through the suspension device 3. At this time, the suspension device 3 is limited by the locking component 35 to prevent it from detaching from the cable during movement. Subsequently, the driving motor 33 drives the guide wheel 34 to rotate, enabling the entire device to move along the surface of the cable, greatly improving the detection efficiency, solving the problem that it is not easy for pedestrians to climb the cable, thereby reducing the detection cost and risk.

[0047] When the locking component 35 is in use, by rotating the rotating cylinder 564 in the limiting component 356, the clamping block 565 is disengaged from the clamping groove 567 in the arc-shaped limiting plate 566. At this time, the elastic force of the tension spring 563 is released, driving the fixed cylinder 561 to slide upward along the surface of the limiting rod 562, and simultaneously driving the connecting plate 351 upward. At this time, the connecting plate 351 pushes the sliding block 352 upward, and then a "mouth" - shaped connection is formed between the fixed frame 32, the sliding block 352 and the mounting plate 31. This "mouth" - shaped connection can effectively prevent the cable from detaching from the device. Even when the device is subject to external interference or the cable shakes, it can maintain a firm connection between the device and the cable, reducing the possibility of the device accidentally falling off and reducing the potential harm to surrounding personnel and facilities.

[0048] The operation of the locking component 35 is simple. Just rotate the rotating cylinder 564 to achieve locking. It reduces the working difficulty and operation time of the operator, improves the use efficiency of the device, and reduces the time required to fix the device on the cable through the quick - limiting function. This enables the detection personnel to deploy the device faster and start the fault detection work, improving the overall detection efficiency and enhancing the emergency response ability of the device.

[0049] At the same time, the sliding plate 353 moves upward together with the sliding block 352 under the push of the elastic piece 355, and then the surface of the pressing wheel 354 comes into contact with the cable, further enhancing the fixing effect of the device on the cable. The close contact between the pressing wheel 354 and the cable increases the friction between the device and the cable, preventing the device from slipping during movement and ensuring that the device can move stably along the surface of the cable.

[0050] Among them, the elastic effect of the elastic piece 355 enables the pressing wheel 354 to adapt to cables of different sizes. When encountering a thicker cable, the elastic piece 355 will be compressed to ensure that the pressing wheel 354 can still closely fit the surface of the cable; for a thinner cable, the elastic force of the elastic piece 355 can make the pressing wheel 354 maintain sufficient pressure to ensure the stability of the device. This adaptability improves the versatility of the device, enabling it to perform fault detection and location on power transmission and distribution lines of different specifications.

[0051] When detecting through the detection device 2 on the top of the support plate 1, the servo motor 24 drives the driving wheels 25 on both sides of the housing 21 to rotate simultaneously through the pulley group, so that the accompanying ring body 23 can perform a circular motion along the surface of the semi-circular rail positioning ring 22. The boosting wheel 29 can reduce the frictional resistance when the accompanying ring body 23 runs. This motion mode enables the detection probe 28 installed on the accompanying ring body 23 to detect the power transmission and distribution line at different angles and positions. At the same time, by adjusting the length of the telescopic rod 27, the detection probe 28 can be more accurately aligned with the fault point, improving the detection accuracy and reliability and reducing the possibility of missed fault detection.

[0052] Among them, the open design of the semi-circular rail positioning ring 22 and the accompanying ring body 23 also enables the cable to pass through the middle of the accompanying ring body 23 more quickly and conveniently. The open design of the semi-circular rail positioning ring 22 and the accompanying ring body 23 has great flexibility. The cable can pass through the middle of the accompanying ring body 23 more quickly and conveniently, which enables the device to adapt to different cable layouts and installation methods. Whether it is an overhead line or an underground cable, the device can be easily installed on the cable for detection. This open design also facilitates the installation and disassembly of the device and improves the operability of the device.

[0053] When the anti-shake assembly 26 is in use, when the device shakes due to external interference, the swing plate 262 outside the mounting frame 261 will swing under the action of inertia. The counterweight 263 at the bottom plays a role in stabilizing the center of gravity, increasing the stability and inertia of the swing, which helps to improve the adaptability of the device to external interference and enables the device to maintain a relatively stable operating state under different external conditions.

[0054] When the shaking amplitude is relatively large, the swing plate 262 will contact the buffer block 265. The buffer block 265 slides on the arc-shaped guide rail 264, forcing the compression spring 266 to be compressed. The arc-shaped guide rail 264 provides a guiding function for the movement of the buffer block 265. The movement of the buffer block 265 converts the shaking energy into frictional force and elastic potential energy, thus playing a buffering role, reducing the shaking amplitude of the device and reducing the safety risk.
