Description

Technical Field

[0001] The present invention belongs to the technical field of cable fault detection, and particularly relates to an overhead cable fault detection device for a wind power station. Background Art

[0002] In recent years, with the continuous deepening of the reform of power enterprises in China, the power supply scope has been continuously expanded, and the mileage of high-voltage cables laid in the power grid has also been increasing. In order to ensure the stable operation of the national power grid, a large number of maintenance personnel are fighting on the front line. At present, most high-voltage transmission cables are erected in the air. During maintenance and fault repair, workers need to climb above the iron racks to operate. Sometimes, they even need to shuttle between the iron racks along the cable for inspection. Such maintenance work does not allow for good rest during the process, has extremely high physical requirements for workers. Coupled with the fact that the attention of workers working at heights must be highly concentrated, it accelerates the physical consumption of workers, making working at heights even more dangerous. A slight mistake may lead to an accident. For this reason, various countries are actively researching and developing fault detection robots that can replace workers. When the detection robot conducts inspections on high-voltage cables, there may be sundries such as kite strings and plastic bags on the high-voltage cables affected by wind. When the fault detection robot passes by, the sundries are easily wound into the moving wheels of the equipment, resulting in equipment failures and affecting the normal operation of the fault detection robot. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an overhead cable fault detection device for a wind power station. In this device, the moving component can drive the swing arm to swing around the fixed axis. During the movement of the swing arm, the swing arm can drive the debris removal knife to move, thereby removing the sundries on the cable, and can also prevent the sundries from being wound around the moving wheel, resulting in the inability of the moving wheel to move normally, ensuring the normal operation of the device.

[0019] The detection component of this device is used to detect the cable. When the third cylinder retracts, it drives the moving plate to move. The movement of the moving plate will pull one end of the push rod to move. The movement of one end of the push rod will drive the sliding blocks on both sides to approach the support plate. When the sliding blocks move, they will drive the vertical plate to move towards the middle. The movement of the vertical plate towards the middle will drive the semi-circular plate and several detection cameras evenly installed on the semi-circular plate to move towards the middle. The several detection cameras are arranged in a circular pattern, thus achieving the purpose of detecting the cable comprehensively.

[0020] The setting of the marking mechanism of this device can mark both sides of the detected fault, facilitating subsequent repair of the fault. The motor drives the first rotating arm to rotate, and the fixed column at the end of the first rotating arm will slide along the strip groove on the cross bar, thereby driving the cross bar and the third rack to move up and down along the guide rail. The third rack meshes with the second gear. During the movement of the third rack, it drives the second gear to rotate. The rotation of the second gear drives the rotating shaft to rotate, and the rotation of the rotating shaft will drive the fixture and the brush to rotate. The brush contacts the cable, thereby brushing the pigment on the cable to achieve the purpose of marking the fault on the cable.

[0021] The setting of the storage mechanism of this device can store the pigment and at the same time facilitate the replenishment of the pigment for the brush, ensuring that the brush can apply the pigment on the cable and ensuring that the marking mechanism can mark the fault on the cable.

[0022] The stable component of this device can stabilize the support plate, ensuring that the support plate is always in a stable state during operation. The setting of the telescopic rod ensures that the device can be installed on two cables of different sizes, ensuring the normal operation of the device.

[0023] The setting of the driving motor, pulling rod, threaded rod, and moving block of this device facilitates driving the telescopic rod to rotate around the connection point of the telescopic rod and the fixed frame, ensuring the normal rotation of the telescopic rod and at the same time ensuring the purpose of the stable component to stabilize the support plate.

[0038] As Figure 1 shown, the overhead cable fault detection device for a wind power station includes a support plate 1. Moving wheels 8 are provided at both ends of the support plate 1. The arrangement of the moving wheels 8 facilitates the movement of the device on the cable, so as to achieve the purpose of detecting the cable. A moving component 6, a detection component 5 and a stabilizing component 7 are provided on the support plate 1. The moving component 6 is arranged in the middle of the support plate 1, and a debris removal mechanism 4 is arranged on the moving component 6; the moving component 6 can drive the debris removal mechanism 4 to work, ensuring that the debris on the cable can be cleaned by the debris removal mechanism 4 during the movement, and ensuring the normal operation of the device.

[0039] The detection component 5 is arranged on both sides of the support plate 1. A marking mechanism 3 for marking the fault location of the cable and a containing mechanism 2 cooperating with the marking mechanism 3 are further arranged on the detection component 5. The stabilizing component 7 is arranged at the other end of the support plate 1, and the stabilizing component 7 is used to ensure the normal operation of the support plate 1 and ensure the detection quality of the device for the cable.

[0040] In this embodiment, as Figure 3As shown, the obstacle removal mechanism 4 includes a swing arm 401, an obstacle removal blade 404, and a fixed shaft 402. The swing arms 401 are symmetrically arranged on both sides of the support plate 1. The swing arm 401 and the fixed shaft 402 cooperate to drive the obstacle removal blade 404 to move up and down, so as to remove the sundries on the cable line. The fixed shaft 402 is fixedly installed at one end of the support plate 1. A strip-shaped hole 403 is formed in the middle of the swing arm 401, and the fixed shaft 402 is arranged in the strip-shaped hole 403. The obstacle removal blade 404 is arranged at one end of the swing arm 401 and is used to cut and remove the sundries wound on the cable line. The other end of the swing arm 401 is rotatably installed on the moving component 6.

[0041] When the first cylinder 601 extends, it pushes the sliding frame 602 to move along the installation hole 101. During the movement of the sliding frame 602, the other end of the second rotating rod 604 will be pushed to move along with the sliding frame 602. The hinged joint of the first rotating rod 603 and the second rotating rod 604 will move upward, driving the other end of the swing arm 401 to move upward along with the hinged joint of the first rotating rod 603 and the second rotating rod 604. The upward movement of the other end of the swing arm 401, in cooperation with the fixed shaft 402 and the strip-shaped hole 403, causes the obstacle removal blade 404 at one end of the swing arm 401 to move up and down, thereby cleaning the sundries on the front-end cable line and ensuring the normal operation of the device.

[0042] In this embodiment, as Figure 2 , Figure 3 shown, the moving component 6 includes a first cylinder 601, a first rotating rod 603, a second rotating rod 604, a sliding frame 602, and a fixing member 605. An installation hole 101 is formed in the support plate 1. The sliding frame 602 is slidably arranged in the installation hole 101. One end of the first rotating rod 603 and the second rotating rod 604 are hinged. The other end of the swing arm 401 is rotatably installed at the hinged joint of the first rotating rod 603 and the second rotating rod 604. The other end of the first rotating rod 603 is rotatably installed on the side wall of the installation hole 101. The other end of the second rotating rod 604 is rotatably installed on the sliding frame 602. The first cylinder 601 is arranged on the support plate 1 and is used to drive the sliding frame 602 to move along the installation hole 101. The fixing member 605 is arranged at the bottom of the sliding frame 602, and the sliding frame 602 is used to ensure the normal installation and operation of the fixing member 605.

[0043] The moving component 6 can drive the device to move along the cable, ensuring that the device can detect the entire cable. When the first cylinder 601 extends, it pushes the sliding frame 602 to move along the mounting hole 101. During the movement of the sliding frame 602, the other end of the second rotating rod 604 will follow the movement of the sliding frame 602, and the hinged joint between one end of the second rotating rod 604 and the first rotating rod 603 will move upward. When the sliding frame 602 moves to the designated position, the fixing member 605 is fixed on the cable. Then, the piston rod of the first cylinder 601 is retracted. Since the sliding frame 602 is fixedly installed on the cable, the support plate 1 will move along the cable during the retraction of the piston rod of the first cylinder 601. When the first cylinder 601 retracts to the designated position, the clamping of the fixing member 605 on the cable is released, and the above steps are continued. In this way, the purpose of driving the device to move on the cable can be achieved.

[0044] In this embodiment, as Figure 5 shown, the sliding frame 602 includes a sliding plate 6023, a top plate 6022, and a bottom plate 6020. The sliding plate 6023 is slidably disposed in the mounting hole 101.

The top plate 6022 is fixedly installed on the top of the sliding plate 6023, and the piston rod of the first cylinder 601 is connected to the top plate 6022. The bottom plate 6020 is fixedly installed on the bottom of the sliding plate 6023. The fixing member 605 is disposed at the bottom of the bottom plate 6020. The settings of the top plate 6022 and the support plate 6021 can limit the sliding plate 6023, preventing the sliding plate 6023 from falling out of the mounting hole 101 during operation, ensuring the normal operation of the sliding frame 602. The setting of the bottom plate 6020 is used to support the fixing member 605, ensuring the normal operation of the fixing member 605.

[0045] In this embodiment, as Figure 2 shown, a guiding hole 102 is formed on the side wall of the mounting hole 101. The installation shaft 6019 is slidably disposed in the guiding hole 102. The setting of the guiding hole 102 can guide the installation shaft 6019, ensuring the normal operation of the installation shaft 6019.

[0046] In this embodiment, as Figure 5As shown, the sliding carriage 602 further includes a supporting plate 6021. The supporting plate 6021 is disposed at the bottom of the supporting plate 1 and is slidably engaged with the supporting plate 1. The supporting plate 6021 is fixedly installed on the sliding plate 6023. The provision of the top plate 6022 and the supporting plate 6021 can restrict the sliding plate 6023, ensuring that the sliding plate 6023 always moves in the mounting hole 101 and preventing the sliding plate 6023 from shaking up and down during movement, thus ensuring the normal operation of the sliding plate 6023.

[0047] In this embodiment, as Figure 4 shown, the fixing member 605 includes a second cylinder 606, a first clamping rod 6012, a second clamping rod 6017, a third clamping rod 608, a first gear 6014, a connecting rod 6010, a first rack 6013 and a second rack 6018. The first gear 6014 is rotatably installed on the bottom plate 6020 through a shaft. The first rack 6013 and the second rack 6018 are symmetrically disposed on both sides of the first gear 6014, and both the first rack 6013 and the second rack 6018 are meshed with the first gear 6014. The first clamping rod 6012 and the third clamping rod 608 are symmetrically disposed on both sides of the second clamping rod 6017. The second clamping rod 6017 is fixedly installed on the second rack 6018. The first clamping rod 6012 and the third clamping rod 608 can clamp the cable line in cooperation with the second clamping rod 6017. The first clamping rod 6012 is fixedly installed on the first rack 6013. The two ends of the connecting rod 6010 are respectively installed on the first clamping rod 6012 and the second clamping rod 6017. The second cylinder 606 is disposed on the bottom plate 6020, and the piston rod of the second cylinder 606 is connected to the connecting rod 6010.

[0048] The fixing member 605, in cooperation with the first cylinder 601, the first rotating rod 603 and the second rotating rod 604, can drive the supporting plate 1 to move along the cable line to be detected, ensuring the detection quality of the device for the cable line. When the second cylinder 606 drives the clamping plate 609 to move towards the cable line, it will drive the first clamping rod 6012 and the third clamping rod 608 to move towards the cable line at the same time. The movement of the first clamping rod 6012 will drive the first rack 6013 to move. Since both the first rack 6013 and the second rack 6018 are meshed with the first gear 6014, the movement of the first rack 6013 drives the first gear 6014 to rotate. The rotation of the first gear 6014 will drive the second rack 6018 to move. The first rack 6013 and the second rack 6018 move towards the middle or towards the outside at the same time. The movement of the second rack 6018 will drive the second clamping rod 6017 to move. The second clamping rod 6017, in cooperation with the first clamping rod 6012 and the third clamping rod 608, can clamp the cable line.

[0049] In this embodiment, as Figure 4 shown, a slide bar 607 is fixedly installed on the third clamping bar 608. Chute grooves 6011 are formed in the first rack 6013, the second rack 6018 and the slide bar 607. A slide rail 6024 is arranged on the bottom plate 6020. The slide rail 6024 is in sliding fit with the chute grooves 6011. The arrangement of the slide bar 607 can ensure the normal operation of the third clamping bar 608 and ensure the stability of the third clamping bar 608 during the working process. The arrangement of the slide rail 6024 can, on the one hand, serve the purpose of guiding the first rack 6013 and the second rack 6018, and on the other hand, can prevent the first rack 6013 and the second rack 6018 from tilting during the working process, ensuring that the first rack 6013 and the second rack 6018 are always meshed with the gear.

[0050] In this embodiment, as Figure 4 shown, the fixing member 605 further includes a clamping plate 609. Both sides of the clamping plate 609 are respectively connected to the first clamping bar 6012 and the third clamping bar 608. A clamping block 6016 is arranged on the second clamping bar 6017. V-shaped grooves 6015 are formed in both the clamping plate 609 and the clamping block 6016. The arrangement of the V-shaped grooves 6015 facilitates clamping and fixing the cable, ensuring the normal operation of the device.

[0051] In this embodiment, as Figure 6 shown, the detection assembly 5 includes a third air cylinder 501, a moving plate 502, a push-pull rod 5010, side ears 503, a sliding block 509, a vertical plate 508 and a semi-circular plate 507 installed on the vertical plate 508. A plurality of detection cameras 506 are installed on the inner wall of the semi-circular plate 507. The side ears 503 are symmetrically arranged on both sides of the support plate 1.

The third air cylinder 501 is arranged at the bottom of the support plate 1. The moving plate 502 is fixedly installed on the piston rod of the third air cylinder 501. The push-pull rods 5010 are symmetrically arranged on both sides of the moving plate 502, and both ends of the push-pull rods 5010 are respectively rotatably connected to the moving plate 502 and the vertical plate 508. The semi-circular plate 507 is arranged on the vertical plate 508.

[0052] The detection component 5 is set to detect the cable. When the third cylinder 501 contracts, it drives the moving plate 502 to move. When the moving plate 502 moves, it will pull one end of the push rod 5010 to move. When one end of the push rod 5010 moves, it will drive the sliding blocks 509 on both sides to approach the support plate 1. While moving, the sliding blocks 509 will drive the vertical plate 508 to move towards the middle. When the vertical plate 508 moves towards the middle, it will drive the semi-circular plate 507 and several detection cameras 506 evenly installed on the semi-circular plate 507 to move towards the middle. The several detection cameras 506 are arranged in a circular pattern, thus achieving the purpose of detecting the cable comprehensively.

[0053] In this embodiment, as Figure 6 shown, the detection component 5 further includes a guide rod 505. The guide rod 505 is arranged in the fixing hole 504, and both ends of the guide rod 505 are fixedly installed on the side wall of the support plate 1 and the inner wall of the fixing hole 504 respectively. The sliding block 509 is in sliding fit with the guide rod 505. The setting of the guide rod 505 can play a guiding role and can also play a role in supporting the sliding block 509, ensuring that the sliding block 509 is always in a stable state during the working process.

[0054] In this embodiment, as Figure 7 、 Figure 8 shown, the marking mechanism 3 includes a second gear 302, a rotating shaft 303, a third rack 3012, a mounting seat 301, a cross bar 3010, a first rotating arm 304, a bracket 306 and a motor 305. The mounting seat 301 is fixedly installed on the vertical plate 508. The rotating shaft 303 is rotatably installed on the mounting seat 301.

The cross bar 3010 is fixedly installed at the bottom of the third rack 3012. The bracket 306 is fixedly installed at the bottom of the vertical plate 508. The motor 305 is installed on the bracket 306. One end of the first rotating arm 304 is rotatably installed on the motor 305. A fixing column 309 is arranged at the other end of the first rotating arm 304. A strip-shaped groove 3011 is formed in the cross bar 3010. The fixing column 309 is slidably arranged in the strip-shaped groove 3011. Fixing rods 308 are respectively installed at both ends of the rotating shaft 303. A brush 307 is fixedly installed at the end of the fixing rod 308. The brush 307 is used to brush the paint on both sides of the cable fault point.

[0055] The setting of the marking mechanism 3 can mark both sides of the detected fault, facilitating subsequent repair of the fault. The motor 305 drives the first rotating arm 304 to rotate, and the fixed column 309 at the end of the first rotating arm 304 will slide along the strip groove 3011 on the cross bar 3010, thereby driving the cross bar 3010 and the third rack 3012 to move up and down along the guide rail 3013. The third rack 3012 meshes with the second gear 302. During the movement of the third rack 3012, it drives the second gear 302 to rotate. The rotation of the second gear 302 drives the rotating shaft 303 to rotate, and the rotation of the rotating shaft 303 will drive the fixed mount and the brush 307 to rotate. The brush 307 contacts the cable, thereby brushing the pigment on the cable to achieve the purpose of marking the fault on the cable.

[0056] In this embodiment, as Figure 8 shown, guide grooves 3014 are provided on both the cross bar 3010 and the third rack 3012. The guide rail 3013 is fixedly installed on the vertical plate 508, and the guide rail 3013 is in sliding fit with the guide groove 3014. The setting of the guide rail 3013 can play the role of guiding the cross bar 3010 and the third rack 3012, ensuring the normal movement of the cross bar 3010 and the third rack 3012.

[0057] In this embodiment, as Figure 9 shown, the storage mechanism 2 includes a fourth cylinder 201, a support rod 205, a lifting plate 204, a lifting rod 202, and a paint bucket 203. The support rod 205 is fixedly installed on the bracket 306. The lifting plate 204 is arranged below the support rod 205. The fourth cylinder 201 is fixedly installed on the bracket 306, and the piston rod of the fourth cylinder 201 is fixedly installed in the middle of the lifting plate 204. The lifting rods 202 are symmetrically arranged at both ends of the lifting plate 204, and the lifting rods 202 are in sliding connection with the support rod 205. The paint bucket 203 is fixedly installed on the top of the support rod 205. The setting of the storage mechanism 2 can store the pigment and at the same time facilitate the replenishment of the pigment for the brush 307, ensuring that the brush 307 can apply the pigment on the cable and ensuring that the marking mechanism 3 can mark the fault on the cable.

[0058] When the brush 307 on the marking mechanism 3 is in the vertically downward position, the fourth cylinder 201 is opened to drive the lifting plate 204 to move upward. The upward movement of the lifting plate 204 will drive the lifting rod 202 and the paint bucket 203 to move upward until the brush 307 penetrates into the paint bucket 203 to achieve the purpose of replenishing the pigment for the brush 307.

[0059] When the marking mechanism 3 needs to be used, only need to open the fourth cylinder 201 to drive the lifting plate 204 to move downward. While the lifting plate 204 moves downward, it drives the lifting rod 202 and the paint bucket 203 to move downward until the brush 307 is withdrawn from the paint bucket 203, and then open the marking mechanism 3 to mark the cable.

[0060] In this embodiment, as Figure 10 , Figure 11 shown, the stabilizing component 7 includes a fixing frame 701, a telescopic rod 702, a vertical rod 706, and side rods 705 installed on the upper and lower sides of the vertical rod 706.

One end of the telescopic rod 702 is rotatably installed on the fixing frame 701, and the vertical rod 706 is fixedly installed at the other end of the telescopic rod 702. The stabilizing component 7 can achieve the purpose of stabilizing the support plate 1 and ensure that the support plate 1 is always in a stable state during operation. The setting of the telescopic rod 702 ensures that the device can be installed on two cable lines with different dimensions and ensures the normal operation of the device.

[0061] In this embodiment, the stabilizing component 7 further includes a rotating roller 703. Both ends of the rotating roller 703 are rotatably connected to the side rods 705 on the upper and lower sides of the vertical rod 706. The setting of the rotating roller 703 can reduce the friction between the side rod 705 and the cable, and improve the service life of the cable.

[0062] In this embodiment, the stabilizing component 7 further includes a limiting rod 704. A limiting hole 7014 is opened on the upper side rod 705, and a limiting groove 7015 is opened on the lower side rod 705. The limiting rod 704 passes through the limiting hole 7014 and extends into the limiting groove 7015. The settings of the limiting hole 7014 and the limiting groove 7015 can achieve the purpose of installing the limiting rod 704 and ensure the stability of the limiting rod 704 during operation. The setting of the limiting rod 704 can prevent the cable from falling off from the space formed by the side rod 705 and the vertical rod 706, and ensure that the support plate 1 is always in a stable state during operation.

[0063] In this embodiment, as Figure 10As shown in the figure, the stabilizing component 7 further includes a mounting rod 7013, a moving block 7011, a threaded rod 708, a driving motor 709, and a pulling rod 7012.

The two ends of the pulling rod 7012 are respectively rotatably connected to the moving block 7011 and the telescopic rod 702. The settings of the driving motor 709, the pulling rod 7012, the threaded rod 708, and the moving block 7011 facilitate driving the telescopic rod 702 to rotate around the connection point of the telescopic rod 702 and the fixing frame 701, ensuring the normal rotation of the telescopic rod 702, and at the same time ensuring that the stabilizing component 7 can ensure the stability of the support plate 1.

[0064] Among them, the setting of the telescopic rod 702 facilitates the installation of the device on cable lines of different widths, ensuring the adaptability of the device.

[0065] The driving motor 709 drives the threaded rod 708 to rotate. When the threaded rod 708 rotates, it will drive the moving block 7011 to move. When the moving block 7011 moves, it will pull the pulling rod 7012 to move. When the pulling rod 7012 moves, it will drive the telescopic rod 702 to rotate. When the telescopic rod 702 rotates, it will ensure that the rotating roller 703 on the upright rod 706 at the end of the telescopic rod 702 contacts the adjacent cable line.

[0066] In this embodiment, the stabilizing component 7 further includes an inclined rod 707. The two ends of the inclined rod 707 are respectively connected to the mounting rod 7013 and the fixing frame 701. The setting of the inclined rod 707 can strengthen the mounting rod 7013 and ensure the normal operation of the mounting rod 7013.

[0067] The working states of the device include but are not limited to Figure 1 the state described above, and can also include the state where the stabilizing components 7 on both sides of the support plate 1 are unfolded, and the state where the stabilizing components 7 on both sides of the two support plates 1 are retracted.
