Power cables are commonly used in urban underground power grids, cables led out from power stations, internal power supply in industrial and mining enterprises, and underwater power transmission across rivers and seas.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 12 , a power cable detection device, including a base 1 and a controller. The detection device is controlled by the controller. Lower combining frames 11 are fixed to the tops of both ends of the base 1. An electric telescopic rod 12 is fixed to one side of the top of the base 1. The top of the output shaft of the electric telescopic rod 12 is fixed with an upper combining frame 13. A gear shaft 2 is rotatably connected to the inside of one side of the lower combining frame 11. A motor 21 is fixed to the outside of the gear shaft 2. Double-layer gear discs 22 are rotatably connected to the inside of both sides of the upper combining frame 13, and the double-layer gear discs 22 are engaged with the gear shaft 2. A coating component is provided on the top of the base 1, and the coating component is used to coat the cable; The coating component includes a lower combining cylinder 3. A lower ring groove 301 is formed on the surface of the lower combining cylinder 3. A first tooth group 302 is fixed to the outside of the lower combining cylinder 3 near the gear shaft 2. A lower limiting frame 31 is slidably connected to the inside of the lower ring groove 301, and the lower limiting frame 31 is fixed to the base 1. A docking groove 303 is formed at the top of the lower combining cylinder 3. A magnetic sheet 304 is fixed to the bottom of the docking groove 303. An iron rod 32 is clamped in the docking groove 303; The top of the iron rod 32 is fixed with an upper combining cylinder 321. An upper ring groove 322 is formed on the surface of the upper combining cylinder 321. A second tooth group 323 is fixed to the outside of the upper combining cylinder 321 near the first tooth group 302. An upper limiting frame 33 is slidably connected to the inside of the upper ring groove 322, and the upper limiting frame 33 is fixed to the upper combining frame 13. A bracket is fixed to one side of the top of the base 1 near the gear shaft 2, and a motor 34 is fixed to the bracket. A gear is provided on the outside of the output shaft of the motor 34, and the gear is engaged with the first tooth group 302 and the second tooth group 323. A linear laser 4 is fixed to the inside of the upper combining cylinder 321. T-shaped aluminum sheets 41 are fixed to both ends of the linear laser 4; A bidirectional lead screw 5 is rotatably connected to one side of the inside of the lower combining cylinder 3. A limiting rod 51 is fixed to the side of the inside of the lower combining cylinder 3 where the bidirectional lead screw 5 is not provided. Positioning plates 52 are threadedly connected to the outer surfaces of both ends of the bidirectional lead screw 5. Roller groups 53 are rotatably connected to the inside of the positioning plates 52. The positioning plates 52 are both slidably connected to the limiting rod 51. The T-shaped aluminum sheets 41 are both abutted against the positioning plates 52; During the specific operation process, first, start the electric telescopic rod 12 through the controller. Drive the upper combination frame 13 to lift by the electric telescopic rod 12. Drive the double-layer gear disc 22 and the upper limit frame 33 to lift by the upper combination frame 13. Drive the upper combination cylinder 321 to lift by the upper limit frame 33. Thus, the lower combination frame 11 and the upper combination frame 13 are completely separated, the double-layer gear disc 22 and the gear shaft 2 are separated, and at the same time, the lower combination cylinder 3 and the upper combination cylinder 321 are completely separated; At this time, the tester carries the present invention to the power cable to be detected. Then move the present invention so that the power cable is located below the two double-layer gear discs 22, and at the same time, the power cable is located in the middle position between the lower combination cylinder 3 and the upper combination cylinder 321. When both double-layer gear discs 22 are hung upside down on the top of the power cable, at this time, rotate the bidirectional lead screw 5. Drive the two positioning plates 52 to move towards each other through the bidirectional lead screw 5, so that the two positioning plates 52 move towards each other until the two positioning plates 52 move to both sides of the power cable and limit and correct the power cable. Then, the power cable limited by the positioning plates 52 and the linear laser 4 are in a coplanar state, so that the scanning area of the linear laser 4 for the power cable reaches the maximum, thereby improving the detection efficiency of the linear laser 4; Then start the electric telescopic rod 12 through the controller, so that the electric telescopic rod 12 drives the upper combination frame 13 to reset, so that the upper combination frame 13 drives the upper limit frame 33, the upper combination cylinder 321 and the iron rod 32 to reset. During the reset process of the iron rod 32, it is clamped into the internal of the docking groove 303 and adsorbed with the magnetic sheet 304. Thus, the upper combination cylinder 321 and the lower combination cylinder 3 form a complete cylinder, and then the first tooth group 302 and the second tooth group 323 form a complete tooth ring. Through the adsorption effect of the magnetic sheet 304 and the iron rod 32 on each other, the assembly stability of the upper combination cylinder 321 and the lower combination cylinder 3 is improved, and the upper combination frame 13 and the lower combination frame 11 are completely closed. At this time, the power cable is located below the double-layer gear disc 22, and at the same time, the power cable passes through the cylinder formed by the upper combination cylinder 321 and the lower combination cylinder 3. Then the installation of the present invention is completed, so that the present invention can pass the power cable to be detected on the telegraph pole through the present invention without disassembling the power cable, thereby improving the installation convenience of the present invention; Further, after the installation of the present invention is completed, start the motor 21 through the controller. Drive the gear shaft 2 to rotate by the motor 21. Drive the double-layer gear disc 22 to rotate by the gear shaft 2. During the rotation process of the gear shaft 2, under the action of friction, the double-layer gear disc 22 drives the present invention to move self-propelled on the top of the power cable; In the self-propelled movement of the present invention, the motor 34 is started by the controller, and the toothed ring composed of the first toothed group 302 and the second toothed group 323 outside the output shaft of the motor 34 rotates. Since the lower cylinder 3 and the upper cylinder 321 form a complete cylinder under the adsorption of the magnetic sheet 304 and the iron rod 32, when the motor 34 drives only the first toothed group 302 to rotate, the first toothed group 302 drives the lower cylinder 3 to rotate, and then drives the upper cylinder 321 to rotate synchronously. Similarly, when the motor 34 drives only the second toothed group 323 to rotate, the second toothed group 323 drives the upper cylinder 321 to drive the lower cylinder 3 to rotate synchronously. Thus, no matter when the motor 34 meshes with the first toothed group 302 or the second toothed group 323, it can drive the cylinder composed of the lower cylinder 3 and the upper cylinder 321 to rotate; When the cylinder composed of the lower cylinder 3 and the upper cylinder 321 rotates, the one-dimensional laser 4 is driven to rotate by the upper cylinder 321, so that the one-dimensional laser 4 rotates around the power cable. During the rotation of the one-dimensional laser 4, the one-dimensional laser 4 is started by the controller, so that the one-dimensional laser 4 emits line-shaped laser and performs segmented scanning on the power cable. Then, the present invention can perform a larger range of scanning per unit time, thereby improving the efficiency of detecting the power cable.

[0022] It should be noted that the upper cylinder 321 and the lower cylinder 3 of the present invention are made of insulating materials, and the cross-section of the double-layer gear disk 22 is V-shaped. Thus, when the double-layer gear disk 22 is hung upside down on the top of the power cable, it can be applicable to power cables with different diameters. And the V-shaped setting of the double-layer gear disk 22 makes there be enough space between the double-layer gear disk 22 and the gear shaft 2 to ensure that when the gear shaft 2 rotates, it will not contact the power cable, avoiding scratching the power cable; The lower frame 11, 34 and the electric telescopic rod 12 are all arranged on the top of the base 1, making the weight on the top of the base 1 much greater than the weight of the upper frame 13. And the diagonal setting of the upper frame 13 and the motor 34 makes the weight of the base 1 more uniform. Therefore, when the double-layer gear disk 22 is hung upside down on the top of the power cable, the center of gravity of the present invention is located below the power cable, thereby avoiding deflection during the self-propelled process affected by crosswind, and further improving the stability of the one-dimensional laser 4 for detecting the power cable.

[0024] Inside the lower barrel 3, a first lower ring 6 and a third lower ring 64 are respectively fixed on both sides of the positioning plate 52.

A second lower ring 62 is fixed on one side of the lower barrel 3 close to the first tooth group 302, and a second lower shielding plate 621 is fixed on the inner ring of the second lower ring 62. A fourth lower ring 66 is fixed on the side of the lower barrel 3 away from the first tooth group 302, and a fourth lower shielding plate 661 is fixed on the inner ring of the fourth lower ring 66; Inside the upper barrel 321, a first upper ring 61 and a third upper ring 65 are respectively fixed on both sides of the linear laser 4. A first upper shielding plate 611 is fixed on the inner ring of the first upper ring 61, and a third upper shielding plate 651 is fixed on the inner ring of the third upper ring 65. A second upper ring 63 is fixed on one side of the upper barrel 321 close to the second tooth group 323, and a second upper shielding plate 631 is fixed on the inner ring of the second upper ring 63. A fourth upper ring 67 is fixed on the side of the upper barrel 321 away from the second tooth group 323, and a fourth upper shielding plate 671 is fixed on the surface of the inner ring of the fourth upper ring 67; Among them, a liquid injection pipeline 652 is provided inside a third upper shielding plate 651 near the middle of the third upper ring 65. A hard film 653 is fixed on the inner wall of the liquid injection pipeline 652. Side baffles 654 are fixed on both sides of one end of the third upper shielding plate 651 away from the third upper ring 65, and a scraping plate 655 is fixed on one side of the third upper shielding plate 651 close to the side baffle 654; Specifically, on the basis of Embodiment 1, when the lower barrel 3 and the upper barrel 321 form a complete cylinder under the adsorption of the iron rod 32 and the magnetic sheet 304, at this time, the first lower ring 6 and the first upper ring 61 form a complete ring, the second lower ring 62 and the second upper ring 63 form a complete ring, the third lower ring 64 and the third upper ring 65 form a complete ring, and the fourth lower ring 66 and the fourth upper ring 67 form a complete ring. At the same time, the first lower shielding plate 601 and the first upper shielding plate 611 are spliced into a first shielding plate, the second lower shielding plate 621 and the second upper shielding plate 631 are spliced into a second shielding plate, the third lower shielding plate 641 and the third upper shielding plate 651 are spliced into a third shielding plate, and the fourth lower shielding plate 661 and the fourth upper shielding plate 671 are spliced into a fourth shielding plate; Among them, the first shielding plate and the second shielding plate are on the side close to the first tooth group 302, while the third shielding plate and the fourth shielding plate are on the side away from the first tooth group 302. Thus, the first shielding plate and the second shielding plate jointly shield the side of the lower barrel 3 close to the first tooth group 302, while the third shielding plate and the fourth shielding plate shield the side of the lower barrel 3 away from the first tooth group 302. Thus, both ends of the lower barrel 3 and the upper barrel 321 are shielded, and further, the inside of the cylinder of the lower barrel 3 and the upper barrel 321 is in a dark state, thereby improving the visibility of the laser line of the linear laser 4, and thus improving the accuracy of the scanning detection of the linear laser 4; Furthermore, the first lower shutter 601, the first upper shutter 611, the second lower shutter 621, the second upper shutter 631, the third lower shutter 641, the third upper shutter 651, the fourth lower shutter 661, and the fourth upper shutter 671 are all made of rubber, thus enabling these components to have an adaptive ability. After the lower combining cylinder 3 and the upper combining cylinder 321 form a complete cylinder, the first lower shutter 601, the first upper shutter 611, the second lower shutter 621, the second upper shutter 631, the third lower shutter 641, the third upper shutter 651, the fourth lower shutter 661, and the fourth upper shutter 671 are all in contact with the power cable; As the self-propulsion of the present invention progresses, the first lower shutter 601, the first upper shutter 611, the second lower shutter 621, and the second upper shutter 631 move synchronously on the surface of the power cable. At the same time, under the action of the rotation of the lower combining cylinder 3 and the upper combining cylinder 321, the first lower shutter 601, the first upper shutter 611, the second lower shutter 621, and the second upper shutter 631 move along the length direction of the power cable while rotating around the power cable. Then, during the rotation and movement, a scraping operation is performed on the power cable, so that the debris accumulated on the surface area of the power cable is scraped off, and then the surface of the power cable is completely exposed, thereby improving the accuracy of the detection by the linear laser 4.

[0025] It should be noted that the self-propulsion direction of the present invention is from the fourth upper ring 67 to the second upper ring 63, that is, the surface of the power cable is first subjected to a cleaning operation and then can be scanned and detected; The first shutters are arranged at intervals, the second shutters are arranged at intervals, the third shutters are arranged at intervals, and the fourth shutters are arranged at intervals. At the same time, the first shutters and the second shutters are arranged in a staggered manner, and the third shutters and the fourth shutters are arranged in a staggered manner. Thus, under the combined action of the first shutters and the second shutters, not only are all the first lower shutters 601, the first upper shutters 611, the second lower shutters 621, and the second upper shutters 631 in contact with the power cable at the same time, but also the side of the lower combining cylinder 3 close to the first tooth group 302 can be shaded to the greatest extent. Similarly, under the combined action of the third shutters and the fourth shutters, not only can all the third lower shutters 641, the third upper shutters 651, the fourth lower shutters 661, and the fourth upper shutters 671 be in contact with the power cable at the same time, but also the side of the lower combining cylinder 3 away from the first tooth group 302 can be shaded to the greatest extent.

Under the action of the magnetic block 81, the iron sheet 96 drives the connecting pipe 93 to move towards the magnetic block 81. During the movement of the connecting pipe 93, it gradually loses the closure of the liquid outlet 92. Then, the colored epoxy resin in the liquid storage bottle 9 enters the inside of the blanking pipe 91 through the liquid outlet 92, and enters the inside of the connecting pipe 93 through the blanking pipe 91. Then, the colored epoxy resin enters the inside of the receiving pipe 8 through the connecting pipe 93; Subsequently, the colored epoxy resin enters the inside of the connecting channel 324 through the receiving pipe 8, enters the inside of the liquid injection pipeline 652 through the connecting channel 324 and the third upper ring 65, and then controls the magnetic block 81 to be powered off, so that the iron sheet 96 drives the connecting pipe 93 to reset synchronously under the reset action of the spring 95. After the connecting pipe 93 is reset, it closes the liquid outlet 92, thereby avoiding the injection of the colored epoxy resin; Subsequently, the cylinder 72 is started by the controller, so that the cylinder 72 pushes the rubber rod 73 out from the inside of the storage cavity 71 and makes the rubber rod 73 enter the inside of the connection channel 324 to seal the connection channel 324. At this time, there is enough colored epoxy resin stored inside the liquid injection pipe 652. Then, the operation steps of Example 1 and Example 2 can be carried out, so that the linear laser 4 scans and detects the power cable; Further, when the linear laser 4 detects a break on the surface of the power cable, the rotation of the motor 34 is paused by the controller, so that the upper combining cylinder 321 and the lower combining cylinder 3 stop rotating. At the same time, the rotation of the motor 21 is maintained, so that the present invention maintains the self-propelled state. Then, the third upper shielding plate 651 drives the hard film 653, the side baffle 654 and the scraping plate 655 to move towards the break of the power cable until the hard film 653 moves to the break. Then, the cylinder 72 is started by the controller, so that the cylinder 72 further pushes the rubber rod 73, so that the rubber rod 73 further penetrates inside the connection channel 324, and the rubber rod 73 pushes the air in the connection channel 324 and the liquid injection pipe 652 to press the colored epoxy resin and the hard film 653, so that the hard film 653 opens, and then the colored epoxy resin sprays out from the hard film 653 and sprays towards the break of the power cable; When the colored epoxy resin sprays out, it is limited by the two side baffles 654 at the same time, avoiding the colored epoxy resin dripping along the periphery of the power cable. When the direction of the break of the power cable is consistent with the length direction of the power cable, through the self-propelled operation of the present invention, the upper combining cylinder 321 drives the third upper shielding plate 651 and the scraping plate 655 to move along the power cable on the surface of the power cable, and during the movement, the colored epoxy resin is smeared on the break by the scraping plate 655; When the direction of the break of the power cable is consistent with the circumferential direction of the power cable, the motor 34 is continuously started by the controller, so that the gear of the motor 34 continues to drive the upper combining cylinder 321 and the lower combining cylinder 3 to rotate. Then, the upper combining cylinder 321 drives the third upper ring 65 and the third upper shielding plate 651 to rotate around the power cable. Then, the third upper shielding plate 651 drives the side baffle 654 to rotate around the power cable. Thus, during the rotation of the side baffle 654, the colored epoxy resin is smeared on the break of the power cable, which plays a role in repairing the power cable. At the same time, the place where the colored epoxy resin is smeared can leave its corresponding color to mark the repair place of the power cable. Then, when the power cable is finely maintained subsequently, the place that needs to be maintained can be quickly found; Furthermore, when the linear laser 4 continuously detects the power cable, the temperature of the linear laser 4 itself will continuously increase, and the heat dissipated by the linear laser 4 will be transferred to the T-shaped aluminum sheet 41, and then transferred to the positioning plate 52 through the T-shaped aluminum sheet 41, and then the heat will be transferred to the roller group 53 through the positioning plate 52. When the motor 34 drives the upper coiling cylinder 321 and the lower coiling cylinder 3 to rotate, the lower coiling cylinder 3 drives the positioning plate 52 and the roller group 53 to rotate synchronously around the power cable, and then the heat dissipated by the linear laser 4 is transferred to the power cable through the roller group 53, and then the temperature outside the power cable increases; When the heated power cable is repaired with colored epoxy resin, its own temperature can increase the curing speed of the colored epoxy resin, thereby improving the protection of the power cable.

[0028] It should be noted that the top of the liquid storage bottle 9 is provided with a liquid injection port, and the colored epoxy resin stored inside the liquid storage bottle 9 is to be replenished into the internal part of the liquid injection pipe 652. When the damaged part of the power cable passes through the camera 325, the camera 325 records the state of the power cable and judges whether the repair of the colored epoxy resin is completed. If not, the motor 21 is rotated reversely to make the present invention move reversely, and at the same time, the liquid storage bottle 9 replenishes the colored epoxy resin into the liquid injection pipe 652 to ensure the repair of the power cable.

The scope of the present invention is defined by the appended claims and their equivalents.
