At this time, the elastic force of the tension spring is released, and drives the fixed cylinder to slide upward along the surface of the limit rod.

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

[0015] 1. The present invention hangs the entire device on the cable through a suspension device, and limits the suspension device through a locking assembly. Then, the guide wheel is driven by a driving motor to rotate, so that the entire device can move along the surface of the cable, which greatly improves the detection efficiency and solves the problem that it is difficult for pedestrians to climb the cable, thereby reducing the detection cost and risk.

[0016] 2. The present invention provides a locking assembly to form a "mouth"-shaped connection between the fixing 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 subject to external interference or the cable is shaking, the device and the cable can be firmly connected, thereby reducing the possibility of accidental detachment of the device and reducing potential hazards to surrounding personnel and facilities.

[0017] 3. The present invention achieves locking of the locking assembly by rotating the rotating drum. This reduces the operator's work difficulty and operation time, improves the use efficiency of the equipment, and reduces the time used to fix the device on the cable through the rapid limit function. This enables the inspection personnel to deploy the equipment faster and start fault detection work, improves the overall inspection efficiency, and enhances the emergency response capability of the equipment.

[0018] 4. The present invention provides a clamping wheel, and the sliding plate moves upward with the sliding block under the push of the spring sheet, so that the surface of the clamping wheel contacts the cable, further enhancing the fixing effect of the device on the cable. The close contact between the clamping wheel 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.

[0019] 5. The present invention provides a spring sheet, and the elastic effect of the spring sheet enables the clamping wheel to adapt to cables of different sizes. When encountering a thicker cable, the spring sheet will be compressed to ensure that the clamping wheel can still fit closely to the cable surface; while for thinner cables, the elastic force of the spring sheet can keep the clamping wheel under sufficient pressure to ensure the stability of the device. This adaptability improves the versatility of the device, enabling it to detect and locate faults on transmission and distribution lines of different specifications.

[0020] 6. The present invention sets a detection device, and the servo motor drives the driving wheels on both sides of the shell to rotate simultaneously through the pulley group, so that the accompanying ring body can make a circular motion along the surface of the semi-arc track positioning ring, and the booster wheel can reduce the friction resistance of the accompanying ring body during operation. This movement mode enables the detection probe installed on the accompanying ring body to detect the power transmission and distribution lines at different angles and positions. At the same time, by adjusting the length of the telescopic rod, the detection probe can be more accurately aligned with the fault point, thereby improving the accuracy and reliability of detection and reducing the possibility of missed fault detection.

[0021] 7. The present invention provides a semi-arc track positioning ring and a companion ring body. The open design of the semi-arc track positioning ring and the companion ring body allows the cable to pass through the middle of the companion ring body more quickly and conveniently. The open design of the semi-arc track positioning ring and the companion ring body has great flexibility. This allows 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.

[0022] 8. The present invention provides an anti-sway component. When the device is disturbed by external interference and shakes, the swing plate on the outside of the mounting frame will swing under the action of inertia. The counterweight block at the bottom stabilizes the center of gravity and increases the stability and inertia of the swing, which helps to improve the device's adaptability to external interference and enables the device to maintain a relatively stable operating state under different external conditions.

[0023] 9. The present invention provides a buffer block. When the shaking amplitude is large, the swing plate will contact the buffer block. The buffer block slides on the arc guide rail, forcing the compression spring to be compressed. The arc guide rail provides a guide for the movement of the buffer block. The movement of the buffer block converts the shaking energy into friction and elastic potential energy, thereby playing a buffering role, reducing the shaking amplitude of the equipment and reducing safety risks.

[0037] Example: See Figure 1-Figure 11 The present invention provides a technical solution: a mobile power transmission and distribution line fault detection and positioning device, comprising:

[0038] A support plate 1 is used to support the overall components of the equipment; a detection device 2 is used to detect faults in power transmission and distribution lines, and the bottom of the detection device 2 is fixedly connected to the top of the support plate 1; a suspension device 3 is used to drive the fault detection and positioning device to move along the surface of the cable, and the two sides of the detection device 2 are fixedly connected to the outer side of the suspension device 3, and the suspension device 3 is located at the top of the support plate 1; the detection device 2 includes a shell 21, and the top of the shell 21 is fixedly connected to a semi-arc track positioning ring 22, and the outer side of the semi-arc track positioning ring 22 is slidably connected to a companion ring body 23, and the inner side of the companion ring body 23 is fixedly connected to a telescopic rod 27, and the top of the telescopic rod 27 is fixedly The housing 21 is fixedly connected with a detection probe 28, the outer side of the housing 21 is fixedly connected with a servo motor 24, the two sides of the housing 21 are rotatably connected with drive wheels 25, the inner side of the housing 21 is fixedly connected with an anti-sway component 26, and the inner wall of the semi-arc track positioning ring 22 is rotatably connected with a booster wheel 29; the suspension device 3 includes a mounting plate 31, the top of the mounting plate 31 is fixedly connected with a fixing frame 32, the outer side of the fixing frame 32 is fixedly connected with a drive motor 33, the output end of the drive motor 33 is fixedly connected with a guide wheel 34, the inner wall of the mounting plate 31 is slidably connected with a locking component 35, the bottom of the housing 21 is fixedly connected to the top of the support plate 1, and the output end of the servo motor 24 is connected to the outer side of the drive wheel 25 through a pulley group. The outer side of the driving wheel 25 is rollingly connected to the outer wall of the accompanying ring body 23, the side wall of the accompanying ring body 23 is rollingly connected to the outer wall of the booster wheel 29, the two sides of the shell 21 are fixedly connected to the outer side of the mounting plate 31, the inner side of the fixing frame 32 is rotationally connected to the two sides of the guide wheel 34, the top of the locking assembly 35 is slidingly connected to the inner wall of the fixing frame 32, and 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 being separated from the cable during movement. Then, the guide wheel 34 is driven to rotate by the driving motor 33, so that the whole device can move along the surface of the cable, which greatly improves the detection efficiency and solves the problem of pedestrian climbing the cable. The problem of cable is not easy, 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 shell 21 to rotate through the pulley group, so that the accompanying ring body 23 can make a circular motion along the surface of the semi-arc track positioning ring 22. The booster wheel 29 can reduce the friction resistance of the accompanying ring body 23 during operation. This movement mode enables the detection probe 28 installed on the accompanying ring body 23 to detect the power 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, thereby improving the accuracy and reliability of detection and reducing the possibility of missed fault detection.

[0039] Among them, the open design of the semi-arc track positioning ring 22 and the accompanying ring body 23 also allows the cable to pass through the middle of the accompanying ring body 23 more quickly and conveniently. The open design of the semi-arc track 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 equipment and improves the operability of the equipment.

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

[0041] When the shaking amplitude is large, the swing plate 262 will contact the buffer block 265. The buffer block 265 slides on the arc guide rail 264, forcing the compression spring 266 to be compressed. The arc guide rail 264 provides a guide for the movement of the buffer block 265. The movement of the buffer block 265 converts the shaking energy into friction and elastic potential energy, thereby playing a buffering role, reducing the shaking amplitude of the equipment 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 inner side of the sliding block 352, a pressing wheel 354 is rotatably connected to the top of the sliding plate 353, a spring piece 355 is fixedly connected to the bottom of the sliding plate 353, a limiting component 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 spring piece 355 is fixedly connected to the inner side of the sliding block 352, and the top of the limiting component 356 is fixedly connected to the mounting plate 31. 1 is fixedly connected to the bottom, the top of the sliding block 352 is slidably connected to the inner wall of the fixed frame 32, the limiting component 356 includes a fixed cylinder 561, the outer side of the fixed cylinder 561 is rotatably connected to a rotating cylinder 564, the inner side of the rotating cylinder 564 is fixedly connected to a clamping block 565, the top of the fixed cylinder 561 is fixedly connected to a tension spring 563, the center of the fixed cylinder 561 is slidably connected to a limiting rod 562, the bottom of the limiting rod 562 is fixedly connected to an arc-shaped limiting plate 566, the outer side of the fixed cylinder 561 is fixedly connected to the inner side of the connecting plate 351, and the clamping block 565 is fixedly connected to the inner side of the connecting plate 351. The outer side of the arc-shaped limit plate 566 is connected to the inner side of the arc-shaped limit plate 566 through the card slot 567, and the card slot 567 is set in the wall of the arc-shaped limit plate 566. The top of the tension spring 563 and the limit rod 562 are fixedly connected to the bottom of the mounting plate 31. When the locking assembly 35 is in use, the rotating cylinder 564 in the limit component 356 is rotated to disengage the card block 565 from the card slot 567 in the arc-shaped limit plate 566. At this time, the elastic force of the tension spring 563 is released, and the fixing cylinder 561 is driven to slide upward along the surface of the limit rod 562, and the connecting The plate 351 moves upward, and the connecting plate 351 pushes the sliding block 352 upward, thereby forming a "mouth"-shaped connection between the fixing 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 is shaking, the device and the cable can be firmly connected, which reduces the possibility of accidental detachment of the device and reduces the potential harm to surrounding personnel and facilities. The locking assembly 35 is easy to operate and can be locked by simply rotating the rotating drum 564. The operator's work difficulty and operation time are reduced, and the efficiency of equipment use is improved. The quick limit function reduces the time used to fix the device on the cable. It enables detection personnel to deploy equipment faster and start fault detection work, improves overall detection efficiency, and enhances the emergency response capability of the equipment.

[0043] At the same time, the sliding plate 353 moves upward together with the sliding block 352 under the push of the spring 355, so that the surface of the clamping wheel 354 contacts the cable, further enhancing the fixing effect of the device on the cable. The close contact between the clamping 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;

[0044] The elasticity of the spring 355 enables the clamping wheel 354 to adapt to cables of different sizes. When encountering a thicker cable, the spring 355 will be compressed to ensure that the clamping wheel 354 can still fit tightly to the cable surface; while for thinner cables, the elastic force of the spring 355 can keep the clamping wheel 354 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 transmission and distribution lines of different specifications.

[0045] Working principle:

[0046] When in 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 assembly 35 to prevent it from being separated from the cable during movement. Subsequently, the guide wheel 34 is driven by the driving motor 33 to rotate, so that the entire device can be moved along the surface of the cable, which greatly improves the detection efficiency and solves the problem of pedestrians having difficulty climbing cables, thereby reducing detection costs and risks.

[0047] When the locking assembly 35 is in use, the rotating cylinder 564 in the limiting component 356 is rotated to disengage the block 565 from the slot 567 in the arc-shaped limiting plate 566. At this time, the elastic force of the tension spring 563 is released, and drives the fixed 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, thereby forming a "mouth"-shaped connection between the fixing 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, and can maintain a firm connection between the device and the cable even when the device is subject to external interference or the cable is shaking, thereby reducing the possibility of accidental detachment of the device and reducing potential harm to surrounding personnel and facilities.

[0048] The locking assembly 35 is easy to operate, and locking can be achieved by simply rotating the rotating drum 564. This reduces the difficulty and operation time of the operator, improves the efficiency of the equipment, and reduces the time used to fix the device on the cable through the quick limit function. This enables the inspection personnel to deploy the equipment faster and start fault inspection work, improves the overall inspection efficiency, and enhances the emergency response capability of the equipment.

[0049] At the same time, the sliding plate 353 moves upward along with the sliding block 352 under the push of the spring 355, so that the surface of the clamping wheel 354 contacts the cable, further enhancing the fixing effect of the device on the cable. The close contact between the clamping 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] The elasticity of the spring 355 enables the clamping wheel 354 to adapt to cables of different sizes. When encountering a thicker cable, the spring 355 will be compressed to ensure that the clamping wheel 354 can still fit tightly to the cable surface; while for thinner cables, the elastic force of the spring 355 can keep the clamping wheel 354 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 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 simultaneously drives the driving wheels 25 on both sides of the shell 21 to rotate through the pulley group, so that the accompanying ring body 23 can make a circular motion along the surface of the semi-arc track positioning ring 22, and the booster wheel 29 can reduce the friction resistance of the accompanying ring body 23 during its operation. This movement mode enables the detection probe 28 installed on the accompanying ring body 23 to detect the power 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, thereby improving the accuracy and reliability of detection and reducing the possibility of missed faults.

[0052] Among them, the open design of the semi-arc track positioning ring 22 and the accompanying ring body 23 also allows the cable to pass through the middle of the accompanying ring body 23 more quickly and conveniently. The open design of the semi-arc track 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 equipment and improves the operability of the equipment.

[0053] When the anti-sway assembly 26 is in use, when the device is disturbed by external interference and shakes, the swing plate 262 outside the mounting frame 261 will swing under the action of inertia. The counterweight block 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 device's ability to adapt to external interference and enable the device to maintain a relatively stable operating state under different external conditions.

[0054] When the shaking amplitude is large, the swing plate 262 will contact the buffer block 265. The buffer block 265 slides on the arc guide rail 264, forcing the compression spring 266 to be compressed. The arc guide rail 264 provides a guide for the movement of the buffer block 265. The movement of the buffer block 265 converts the shaking energy into friction and elastic potential energy, thereby playing a buffering role, reducing the shaking amplitude of the equipment and reducing safety risks.

[0055] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
