Description

[0002] Cable is one of the basic facilities of the power grid and is responsible for the transmission of raw electric energy. Cable detection not only involves the stable operation of the power system, but is also directly related to the safety of electricity use in rail transit, industrial production, commercial buildings and other fields. Especially in special scenarios such as subway tunnels and submarine cables, accurate cable status assessment often determines the reliability of the entire system. In order to protect the rights and interests of the State Grid, staff will conduct electromagnetic safety inspections on cables when using cable detection devices on a regular basis.

[0003] The existing cable detection devices on the market usually require electricians to clamp the detection end of the device in contact with the outside of the cable to be detected, and judge whether there is leakage or power abnormality by changing the electromagnetic signal of the cable current. However, when detecting multiple cables that are arranged closely, it is inconvenient for electricians to use the detection head to detect a single cable to be detected from between two closely arranged cables, and it is not convenient to use the detection end to switch the position of the outer wall of the cable for interference detection. Dust is easily accumulated on the surface of the wire and in the gap between two adjacent wires, which can easily affect the detection results. Therefore, a cable detection device is needed to solve the problem. Summary of the invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that when detecting a plurality of cables arranged relatively closely, due to the relatively close arrangement between the cables, electricians need to individually switch positions and touch the outer walls of the cables through the detection end for detection, which is particularly inconvenient. Please refer to Figure 1 - Figure 10 Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] A cable detection device includes a cable detector main body 1 and a detection head 35. A drive motor 2 is installed on the outer wall of the cable detector main body 1. The output end of the drive motor 2 is fixedly connected to a winding wheel 3. A detection wire 4 is fixedly connected to the outer wall of the winding wheel 3. The staff holds the first fixed frame 6 in place and starts the drive motor 2. The drive motor 2 will drive the winding wheel 3 at the output end to rotate. When the winding wheel 3 rotates, it will start to gradually wind the detection wire 4 around the outside of the winding wheel 3 for winding. As the detection wire 4 is continuously wound, one end of the detection wire 4 continuously pulls the first rotating disk 15 to move;

[0035] A limiting cable 5 is fixedly connected to the outer wall of the cable detector main body 1. One end of the limiting cable 5 is fixedly connected to a first fixed frame 6;

[0036] A plurality of driving members for moving a plurality of detection heads 35 are arranged in the first fixed frame 6. The driving member includes a first rotating disk 15. One end of the detection wire 4 is fixedly connected to the outer wall of the first rotating disk 15.

[0037] A transmission rack 11 is fixedly connected to the inner wall of the first fixed frame 6. One end of the first rotating disk 15 is rotatably connected to a transmission gear 16. The transmission gear 16 meshes with the transmission rack 11. During the process of being pulled and moving, the first rotating disk 15 will drive the transmission gear 16 to move synchronously. While the transmission gear 16 moves, it will continuously mesh with the transmission rack 11, and the first rotating disk 15 will form a state of moving while meshing with the transmission rack 11 and rotating;

[0038] The inner wall of the first fixed frame 6 is fixedly connected with a transmission rack 11, and one end of the first rotating disk 15 is fixedly connected with a transmission gear 16, and the transmission gear 16 meshes with the transmission rack 11;

[0039] One end of the transmission gear 16 is rotatably connected with a second rotating disk 17. A resisting post 34 is fixedly connected to the second fixed frame 30. An outer wall of the second rotating disk 17 is fixedly connected with a first guide rod 18 for pressing the resisting post 34 to move. When the transmission gear 16 rotates, it drives the second rotating disk 17 to rotate synchronously. When the second rotating disk 17 rotates, it drives the first guide rod 18 to rotate synchronously. The first guide rod 18 will rotate and move at the same time. It should be noted that since the first rotating disk 15 is pulled by the detection line 4, one end of the second rotating disk 17 is rotatably connected to the end of the transmission gear 16. See the appendix Figure 4 In addition, a first sliding guide groove 12 is formed in the inner wall of the first fixed frame 6. A fixed frame 13 is fixedly connected to the outer wall of the first rotating disk 15. The fixed frame 13 slides in the first sliding guide groove 12. A second return spring 14 is fixedly connected to the outer wall of the fixed frame 13. One end of the second return spring 14 is fixedly connected to the inner wall of the first sliding guide groove 12. Therefore, when the second rotating disk 17 and the transmission gear 16 rotate and move at the same time, the rotation of the first rotating disk 15 is restricted by the pulling force of the detection line 4. Therefore, during the movement of the first rotating disk 15, it will drive the fixed frame 13 to move synchronously and stretch the second return spring 14. When the fixed frame 13 moves, it will be limited by the movement of the first sliding guide groove 12. The staff holds the first fixed frame 6 and keeps its position unchanged, and starts the transmission motor 2. The transmission motor 2 will drive the winding wheel 3 at the output end to rotate. When the winding wheel 3 rotates, it will start to gradually wind the detection line 4 around the outer side of the winding wheel 3 for winding. As the detection line 4 is continuously wound, one end of the detection line 4 continuously pulls the first rotating disk 15 to move. During the process of being pulled and moving, the first rotating disk 15 will drive the transmission gear 16 to move synchronously. While the transmission gear 16 moves, it will continuously mesh with the transmission rack 11, and the second rotating disk 17 will form a state of moving and rotating at the same time. The second rotating disk 17 rotates and drives the first guide rod 18 to rotate synchronously, and the first guide rod 18 will rotate and move at the same time.

[0040] Two second guide rods 31 are fixedly connected to the second fixed frame 30. A plurality of fourth sliding guide grooves 43 are also formed in the first fixed frame 6. The second guide rods 31 are slidably arranged on the inner walls of the fourth sliding guide grooves 43.

[0041] An empty groove 7 is formed in the outer wall of the first fixed frame 6. A third return spring 23 is fixedly connected to the outer wall of the first slider 24. One end of the third return spring 23 is fixedly connected to the end of the first sleeve 21. The detection head 35 is installed at one end of the second fixed frame 30. The detection head 35 is electrically connected to the detection line 4 and the cable detector main body 1.

[0042] Two first return springs 9 are fixedly connected to the outer wall of the first fixed frame 6, and one end of the two first return springs 9 is fixedly connected to a fixed block 8. The fixed block 8 is slidably set on the inner wall of the first fixed frame 6. The staff needs to move the two fixed blocks 8 in opposite directions to make the two fixed blocks 8 farther and farther apart. Then, multiple rows of closely arranged wires 10 that need to be tested are placed in the first fixed frame 6. When the fixed block 8 moves, the first return spring 9 will be stretched. By releasing the moving state of the two fixed blocks 8, the first return spring 9 will reset the two fixed blocks 8 with its own rebound force, thereby limiting the entire row of wires 10 to the inner wall of the first fixed frame 6, as shown in the attached figure. Figure 3 In the state shown in , it should be noted that the number of wires 10 can be any number, and the corresponding number of detection heads 35 can be set to be more than the number of wires 10, but it should be noted that detection heads 35 with different spacings need to be adapted according to wires 10 of different diameters.

[0043] An outer wall of the first fixed frame 6 is provided with an empty groove 7, and a third reset spring 23 is fixed to the outer wall of the first slider 24. One end of the third reset spring 23 is fixed to the end of the first sleeve 21. The detection head 35 is installed at one end of the second fixed frame 30. The detection head 35 is electrically connected to the detection line 4 and the cable detector body 1. When the third guide rod 32 moves with the second fixed frame 30, it will move synchronously with the first slider 24. The first slider 24 moves synchronously with the second sleeve 22 along the first sleeve 21, prompting the pulling of the third reset spring 23 to facilitate subsequent reset.

[0044] It should be noted that different spacings of detection heads 35 need to be adapted according to different diameters of wires 10. During the rotation of the first guide rod 18, the detection heads 35 will contact the contact columns 34 at different positions, so that the detection of multiple closely arranged wires 10 can be switched.

[0045] In this embodiment: as the detection line 4 pulls the first rotating disk 15 to move to the left, the first rotating disk 15 moves to the left, and the transmission gear 16 meshes and rotates with the transmission rack 11 through the first rotating disk 15 moving to the left. When the transmission gear 16 rotates, it drives the second rotating disk 17 to rotate synchronously. The second rotating disk 17 is in a state of moving in parallel while maintaining rotation. Therefore, the second rotating disk 17 will rotate synchronously with the first guide rod 18 of the outer wall, and the movement state of the first guide rod 18 is consistent with the second rotating disk 17. During the movement and rotation of the first guide rod 18, it will successively abut against multiple abutment columns 34, causing the abutment columns 34 and the second fixed frame 30 and the corresponding detection head 35 to be moved to abut against the corresponding surface of the wire 10 for detection.

[0046] Embodiment 2. This embodiment aims to facilitate the solution of the problem that dust is likely to accumulate on the surface of the wire and in the gaps between two adjacent wires, which is likely to affect the test results. Please refer to Figure 1 - Figure 10 , a cable detection device. Two dust removal brushes 36 for cleaning the wire 10 are fixed on the outer wall of the second fixed frame 30, and inclined grooves 37 are formed at the ends of the dust removal brushes 36.

[0047] A fixed plate 20 is fixedly connected to the inner wall of the first fixed frame 6. A first sleeve 21 is fixedly connected to the outer wall of the fixed plate 20. A second sleeve 22 is slidably connected to the inner wall of the first sleeve 21. When the third guide rod 32 drives the second fixed frame 30 to move, it will drive the first slider 24 to move synchronously. The first slider 24 drives the second sleeve 22 to move synchronously along the first sleeve 21, facilitating the subsequent resetting by pulling the third return spring 23;

[0048] The inner wall of the first fixed frame 6 is fixedly connected with a first inclined block 38. A first track groove 39 is formed in the first inclined block 38. A third guide rod 32 is slidably connected to the inner wall of the first track groove 39. The end of the third guide rod 32 is rotatably connected with a second ball 33. One end of the third guide rod 32 is fixedly connected with a second fixed frame 30. A second sliding guide groove 29 is formed in the inner wall of the second fixed frame 30. A second slider 27 is slidably arranged on the inner wall of the second sliding guide groove 29. Two fifth return springs 28 are fixedly connected to the outer wall of the second slider 27. The other ends of the two fifth return springs 28 are fixed to the inner wall of the second sliding guide groove 29. One end of the second sleeve 22 is fixedly connected with a first slider 24. A first guide rod 25 is slidably sleeved in the inner wall of the first slider 24. The end of the first guide rod 25 is fixedly connected with the second slider 27. A fourth return spring 26 is sleeved on the outer wall of the first guide rod 25. One end of the fourth return spring 26 is fixed to the inner wall of the second slider 27. When the second rotating disc 17 drives the first guide rod 18 to rotate, the moving track of the first guide rod 18 will sequentially contact the outer wall of the contact post 34, causing the contact post 34 to move forward under force. The movement of the contact post 34 drives the second fixed frame 30 to move synchronously. The movement of the second fixed frame 30 drives the second guide rods 31 on both sides to slide along the fourth sliding guide groove 43. And when the second fixed frame 30 moves, it will drive the third guide rod 32 to slide along the first track groove 39 formed on the inclined surface of the first contact block 38. And the movement of the third guide rod 32 is guided by the track of the first track groove 39, causing the third guide rod 32 to perform a reciprocating movement in the left and right directions when moving along the first track groove 39. At this time, the second fixed frame 30 will move while driving the dust brush 36 to perform a reciprocating brushing movement in the left and right directions. The left and right movement of the second fixed frame 30 will cause the second slider 27 to drive the first guide rod 25 to slide along the inner wall of the first slider 24, and the fourth return spring 26 will be compressed or stretched during the sliding process to facilitate subsequent resetting, so as to perform a reciprocating brushing operation on the surface of the wire 10.

[0049] Two second guide rods 31 are fixedly connected to the second fixed frame 30. A plurality of fourth sliding guide grooves 43 are also formed in the first fixed frame 6. The second guide rods 31 are slidably connected to the inner wall of the fourth sliding guide grooves 43. And as the third guide rod 32 slides along the first track groove 39, since the first track groove 39 is formed on the inclined surface of the first contact block 38, the dust brush 36 will also slowly descend while performing a reciprocating brushing movement in the left and right directions. It should be noted that when the third guide rod 32 drives the second fixed frame 30 to descend along the first contact block 38, at this time, the second slider 27 will adaptively slide along the inner wall of the second sliding guide groove 29 to adapt, and the fifth return spring 28 will be compressed during the sliding process to facilitate subsequent resetting, so as to clean a larger area of the surface of the wire 10. It should be noted that the depth of the fourth sliding guide groove 43 allows the second guide rods 31 on both sides to slide in the fourth sliding guide groove 43.

[0050] As the dust removal brush 36 gradually contacts the surface of the wire 10, the inclined groove 37 formed at the end of the dust removal brush 36 will continuously contact the surface of the wire 10. Due to the inclined surface of the inclined groove 37, the contact will cause the two dust removal brushes 36 to gradually deform and separate. After deformation and separation, the two dust removal brushes 36 are respectively located on both sides of the current wire 10 and between the adjacent wires 10 next to the current wire 10.

[0051] At this time, as the second fixed frame 30 continues to be pushed and moved, the second fixed frame 30 drives the third guide rod 32 to slide from the first track groove 39 into the third sliding guide groove 41. After sliding into the third sliding guide groove 41, the third guide rod 32 will slide into the third sliding guide groove 41. Along with the third guide rod 32, after sliding to the third sliding guide groove 41, the third guide rod 32 continuously slides along the third sliding guide groove 41.

[0052] When the third guide rod 32 slides to the end along the third sliding guide groove 41, at this time, the detection head 35 just contacts the surface of the wire 10 following the movement of the second fixed frame 30 for measurement.

[0053] It should be noted that the detection heads 35 with different spacings need to be adaptively set according to wires 10 of different calibers. During the rotation of the first guide rod 18, it will contact the contact posts 34 at different positions, so as to switch between surface cleaning and detection of multiple closely arranged wires 10.

[0054] A second inclined block 40 is fixedly connected to the first fixed frame 6. A third sliding guide groove 41 is formed in the second inclined block 40. A number of uniformly distributed hemispherical protrusions 42 are fixedly connected to the inner wall of the third sliding guide groove 41. The hemispherical protrusions 42 are hemispherical. At this time, as the second fixed frame 30 continues to be pushed and moved, the second fixed frame 30 drives the third guide rod 32 to slide from the first track groove 39 into the third sliding guide groove 41. And after sliding into the third sliding guide groove 41, the third guide rod 32 will slide into the third sliding guide groove 41. And with the third guide rod 32, after sliding to the third sliding guide groove 41, as the third guide rod 32 continuously slides along the third sliding guide groove 41, since a number of uniformly distributed hemispherical protrusions 42 are provided in the third sliding guide groove 41, and the hemispherical protrusions 42 are hemispherical, when the third guide rod 32 slides and contacts the surface of the hemispherical protrusions 42, it will cause the third guide rod 32 to drive the second fixed frame 30 to slide up and down. While the second fixed frame 30 slides up and down, it drives the dust brush 36 to slide up and down synchronously to clean the dust in the gap between two adjacent electric wires 10. And because the third sliding guide groove 41 is formed on the inclined surface of the second abutting block 40, the moving track of the dust brush 36 is to reciprocate up and down while moving up uniformly, and brush up and down the gap between the two electric wires 10.

[0055] When the third guide rod 32 slides to the end along the third sliding guide groove 41, at this time, the detection head 35 just contacts the surface of the electric wire 10 following the movement of the second fixed frame 30 for measurement.

[0056] It should be noted that the detection heads 35 with different spacings need to be adaptively set according to electric wires 10 with different calibers. During the rotation of the first guide rod 18, it will contact the abutting posts 34 at different positions, so as to switch the surface cleaning and detection of a plurality of closely arranged electric wires 10.

[0057] In this embodiment: By starting the driving motor 2, the dust brush 36 is caused to move in a small reciprocating motion in the left-right direction during the process of continuously approaching the electric wire 10 to clean the dust on the surface of the electric wire 10. And the dust brush 36 will move in a way that the lower it is at the position closer to the electric wire 10, so as to clean the surface of a larger range of the electric wire 10 to reduce the influence of dust on the detection result. By continuing to start the driving motor 2, after the dust brush 36 has cleaned the dust on the surface of the electric wire 10, during the process of continuing to approach the electric wire 10, it continuously moves in a small reciprocating motion up and down, and the distance between the two dust brushes 36 is caused to become larger and larger, so that the dust brush 36 can clean the longitudinal gap between two adjacent electric wires 10 during the process of moving up and gradually separating, further cleaning the dust accumulated on the electric wire 10 and reducing the influence of dust on the contact detection between the detection head 35 and the electric wire 10.
