Abstract
Description
Technical Field
[0001] The present invention relates to the field of maintenance of high-voltage electric power lines, and more particularly to a leakage current detection component for maintenance of high-voltage electric power lines. Background Art
[0002] Leakage inspection and maintenance of high-voltage power lines refers to the use of electrical testing equipment to detect whether the lines are energized and whether there is leakage during the maintenance of high-voltage transmission lines, so as to ensure the safety of the maintenance work and the reliable operation of the power grid.
[0003] In order to solve the problem that existing leakage current detection and maintenance requires manual climbing operation, the existing technology (Chinese invention patent application publication number CN112595883A) discloses a high-sensitivity leakage current detection component for power high-voltage line maintenance. The component hardens the electrorheological element inside the squeezing ball, thereby pushing the push plug outward, causing the reminder plate to expand and issue a leakage warning. Although this can avoid manual climbing for current detection, the component needs to be installed in advance outside the high-voltage line. Since the component is not equipped with a moving structure, it cannot actively move axially on the high-voltage line. If it is desired to conduct leakage current detection on the entire high-voltage line, the component needs to be installed completely covering the outside of the high-voltage line, which will significantly increase the cost.
[0004] At the same time, in the existing technology, drones are often used to mount maintenance robots on high-voltage lines, and the maintenance robots move on the high-voltage lines to complete leakage detection of the high-voltage lines. For example, the semi-automatic robot Expliner developed by Japan's HiBot company can inspect high-voltage wires. This robot mobile detection method is lower in cost than the leakage detection components disclosed in the above-mentioned existing technology. However, the semi-automatic robots currently used for inspecting high-voltage wires mostly adopt a double-row hanging mobile structure, which needs to be hung on two high-voltage wires aligned in the horizontal direction to achieve movement. However, in many scenarios, the high-voltage line may be single or irregularly arranged (such as a circular array, vertical arrangement, inclined distribution, etc.). Traditional robots cannot be used in these cases, so the applicability of such robots is poor. Summary of the Invention

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] (1) This solution adopts three hanging and shifting components arranged in a collinear and equidistant manner. Regardless of whether the high-voltage line is arranged in a single or irregular manner, the three hanging and shifting components can hang the electrical test component on a single high-voltage line. By extending the hanging part and rotating it, the entire electrical test component is driven to move on the high-voltage line, and the high-voltage line is tested for leakage, which has better applicability. At the same time, this application adopts three hanging and shifting components. When moving over obstacles on a single high-voltage line, there are always two hanging and shifting components hanging on the high-voltage line, providing at least two support points, and better stability during the obstacle crossing process.
[0022] (2) This solution is provided with an anti-sway stabilization component, which pushes the slide toward the high-voltage line through an electric push rod, so that the rubber roller contacts the outer surface of the high-voltage line. When the extended hanging part rotates and moves axially on the high-voltage line, the contact friction between the rubber roller and the surface of the high-voltage line can provide a certain anti-torque effect, thereby limiting the circumferential rotation of the support part and suppressing a certain degree of circumferential swing, ensuring that the electrical detection component maintains a relatively stable orientation, improving the accuracy of image and signal acquisition, and improving the accuracy of electrical detection.
[0023] (3) This solution is provided with a displacement adjustment component, which pushes the slide seat 2 toward the high-voltage line through the electric push rod 2, so that the rubber roller body contacts the outer surface of the high-voltage line. When the component is affected by wind during movement, causing the support part to rotate around the wire at a small angle, the rubber roller body is driven to rotate and the friction generated between the rubber roller body and the surface of the wire is used to correct the angle of the test component to ensure that the test component maintains the correct direction and improve the data collection accuracy. At the same time, during the obstacle crossing process, the test component usually needs to temporarily release the clamping of a hanging displacement component, then cross the insulator, suspension clamp or other obstacles, and finally resume the clamping and continue to move forward. In this process, the robot may change or rotate its posture due to the adjustment of the support point. The angle of the test component during the obstacle crossing process is adjusted by the displacement adjustment component to ensure that the test component can quickly return to the correct posture after the obstacle.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0035] See also Figures 1 to 8 A leakage current detection component 3 for repairing a high-voltage power line comprises a base 1 and three hanging and shifting components 2 connected to the base 1 and arranged in a collinear and equidistant manner;
[0036] The suspension shifting assembly 2 includes two supporting parts 21 rotatably connected to the inside of the base 1 and symmetrical to each other at one end, two plates 22 respectively fixed to the inner walls of the free ends of the two supporting parts 21, two wheels 23 rotatably connected to one side of one plate 22, a wheel 23 rotatably connected to one side of the other plate 22, three extended suspension parts 24 respectively fixed to one side of the three wheels 23, and a motor 25 respectively fixed to the other side of the two plates 22 and driving the wheels 23 and the extended suspension parts 24 to rotate;
[0037] One side of one pair of the plates 22 is connected to an electrical testing assembly 3 , and the electrical testing assembly 3 includes an infrared thermal imager 31 fixed to one side of the plate 22 , a camera 32 , an arc frame 33 , an electric field sensor 34 fixed to the inner wall of the arc frame 33 , and a distance sensor 35 .
[0038] The base 1 is provided with a plurality of movable grooves 11 , one end of each of the plurality of support portions 21 is rotatably connected to the inner walls of the plurality of movable grooves, and the inner walls of the plurality of movable grooves are fixed with limit blocks 12 for limiting the rotation range of the support portions 21 .
[0039] The base 1 is internally connected to three driving components 9 for driving one end of the three pairs of support parts 21 to rotate respectively. The driving components 9 include two gears 95 rotatably connected to the base 1, a seat body 93 slidably connected to the base 1, tooth keys 94 opened on both sides of the seat body 93 and respectively engaged with the two gears 95, and a screw rod 92 rotatably connected to the base 1 and screwed to the seat body 93 for driving the seat body 93 to perform radial movement. One side of the two gears 95 is respectively fixed to one side of the end of the two support parts 21, and three motors 91 are fixed to the lower end of the base 1, and the output shafts of the three motors 91 pass through the base 1 and are respectively fixed to the lower ends of the three screw rods 92.
[0040] By adopting the above technical solution, in the initial state, the three pairs of support parts 21 in the three hanging and shifting components 2 are all in an inclined and outward-expanding state (the two support parts 21 form a V shape). The base 1 is lifted by the drone, and the high-voltage line is located between the three pairs of support parts 21. The motor 4 91 drives the screw rod 92 to rotate, and the rotation of the screw rod 92 drives the seat body 93 to move downward. The downward movement of the seat body 93 drives the gear 95 to rotate through the tooth key 94, and the rotation of the gear 95 drives the support part 21 to rotate, so that multiple support parts 21 are changed from an inclined state to a vertical state. The two support parts 21 in a pair are perpendicular to the base 1, and the extended hanging parts 24 inside the two support parts 21 can respectively contact the left and right sides of the upper surface of the high-voltage line. The component is hung on the high-voltage line through the extended hanging part 24, and the motor 1 25 drives the wheel body 23 and the extended hanging part 24 (fixed The column on one side of the wheel body 23 and the rubber sleeve fixed to the outside of the column rotate, and the extended hanging part 24 rotates to drive the device to move axially on the high-voltage line. When the hanging shift component 2 moves on the high-voltage line, the camera 32 can transmit the collected image of the outside of the high-voltage line back to the control center in real time. The human judges whether the high-voltage line is damaged or leaking by observing the image; at the same time, the infrared thermal imager 31 captures the temperature distribution of the high-voltage line and identifies the overheating area. High-voltage leakage or poor contact will cause local resistance to increase, causing abnormal heating. The infrared thermal imager 31 is used to detect the leakage of the high-voltage line; the electric field sensor 34 is used to detect the alternating electric field around the high-voltage line. The electric field sensor 34 can be a capacitive sensor or an electromagnetic sensor. The capacitive sensor uses the coupling capacitance formed between the high-voltage line and the sensor electrode. When the high-voltage line wire is energized, its alternating electric field induces a weak AC voltage on the sensor electrode. This weak signal is amplified by a high-impedance amplifier to detect changes in the electric field strength. Electromagnetic sensors are based on Faraday's principle of electromagnetic induction. When the alternating current in a high-voltage wire generates an alternating magnetic field, a closed coil is placed in the magnetic field. Electromotive force is induced in the coil. Detecting this induced voltage or current can indicate whether the wire is charged and the magnitude of the current. This allows for leakage detection of high-voltage lines through voltage or current.
[0041] When the present application moves on the high-voltage line and encounters obstacles such as cable gaskets and suspension clamps, the obstacle control action is as follows: the motor four 91 on the far right of the lower end of the base 1 works to drive the two rightmost support parts 21 to rotate, so that the two support parts 21 change from a vertical state to an inclined outward state. At this time, the leftmost and middle hanging shift components 2 work to drive the entire component to move to the right on the high-voltage line, and the obstacle moves to between the rightmost hanging shift component 2 and the middle hanging shift component 2, and then the two rightmost support parts 21 are rotated to a vertical state and the extended hanging part 24 is hung on the high-voltage line. The middle motor four 91 is controlled to work to change the two middle support parts 21 from a vertical state to an inclined outward state. At this time, the leftmost and rightmost hanging shift components 2 work to drive the entire component to move to the right on the high-voltage line, and the obstacle moves To between the leftmost hanging and shifting component 2 and the middle hanging and shifting component 2, then the two middle support parts 21 are rotated to a vertical state and the hanging part 24 is extended to hang on the high-voltage line, and the leftmost motor four 91 is controlled to work so that the two leftmost support parts 21 are changed from a vertical state to an inclined outward state. At this time, the middle and rightmost hanging and shifting components 2 work to drive the entire component to move to the right on the high-voltage line, and the obstacle moves to the left side of the leftmost hanging and shifting component 2, and finally the two left support parts 21 are rotated to a vertical state and the hanging part 24 is extended to hang on the high-voltage line to complete the obstacle crossing action. Since three hanging and shifting components 2 are used, when obstacle crossing movement is performed on a single high-voltage line, there are always two hanging and shifting components 2 hanging on the high-voltage line, providing at least two support points, and better stability during the obstacle crossing process.
[0042] like Figure 4 and Figure 5 As shown, the interior of the plurality of said plate bodies 22 are all connected with an anti-sway stabilization component 4, and the anti-sway stabilization component 4 includes a slide groove 1 opened in the interior of the plate body 22, a slide seat 42 sliding in the slide groove 1, a plurality of movable seats 43 connected to the interior of the slide seat 1 42, and a plurality of rubber rollers 44 rotatably connected to one side of the plurality of movable seats 43. An electric push rod 1 41 is fixedly connected to one side of the plurality of said plate bodies 22, and the telescopic end of the electric push rod 1 41 passes through the plate body 22 and is fixedly connected to one side of the slide seat 1 42. The plurality of said rubber rollers 44 are fitted with the outer surface of the high-voltage line to form radial compression, and there is relative rolling between the plurality of rubber rollers 44 and the surface of the high-voltage line.
[0043] A plurality of movable grooves 2 45 are provided inside the slide seat 1 42 , and a plurality of movable seats 43 are slidably connected in the plurality of movable grooves 2 45 , a plurality of springs 46 are connected inside the plurality of movable grooves 2 45 , and the two ends of the spring 46 are respectively connected to the inner wall of the movable groove 2 45 and one side of the movable seat 43 .
[0044] By adopting the above technical solution, in the process of the extended hanging part 24 rotating to drive the entire assembly to move on the high-voltage line, the electric push rod 41 works to extend and push the slide 42 to move toward the high-voltage line. The movement of the slide 42 toward the high-voltage line can enable multiple rubber rollers 44 to contact the outer surface of the high-voltage line. When the extended hanging part 24 moves axially on the high-voltage line, the contact friction between the rubber rollers 44 and the surface of the high-voltage line can provide a certain anti-torque effect, thereby limiting the circumferential rotation of the support part 21 and suppressing a certain degree of circumferential swing, ensuring that the device maintains a relatively stable orientation, improving the accuracy of image and signal acquisition, and improving the accuracy of electrical testing.
[0045] like Figure 4 and Figure 5 As shown, a shift adjustment component 5 is also connected to the interior of the plurality of the plate bodies 22, and the shift adjustment component 5 includes a slide groove 2 opened in the interior of the plate body 22, a slide seat 2 slidably connected in the slide groove 2, a rubber roller body 53 rotatably connected to the interior of the slide seat 2 52, and a motor 2 54 fixed to one side of the slide seat 2 52, and the output shaft of the motor 2 54 is fixed to one end of the rubber roller body 53. A plurality of electric push rods 2 51 are also fixed to one side of the plurality of the plate bodies 22, and the telescopic end of the electric push rod 2 51 passes through the plate body 22 and is fixed to one side of the slide seat 2 52. The plurality of rubber roller bodies 53 are in contact with the surface of the high-voltage line and form rolling friction with the surface of the high-voltage line when the rubber roller body 53 rotates. The lower end of the base 1 is fixed to the inertia measurement unit 10.
[0046] By adopting the above technical solution, when the inertial measurement unit 10 (including accelerometer + gyroscope + magnetometer, which can measure the rotation angle of the suspension displacement component around the wire in real time, and is often used for posture detection of drones and robots, and is a mature existing technology, which will not be repeated here) detects that the angle of the base 1 is offset (the entire component is affected by the wind during movement and the angle changes caused by the circumferential movement outside the high-voltage line), the suspension displacement component 2 stops moving on the high-voltage line. At the same time, the electric push rod 1 41 contracts to separate the rubber roller 44 from the outer surface of the high-voltage line, and the electric push rod 2 51 extends to push the slide 2 52 toward the high-voltage line, so that the rubber roller body 53 contacts the outer surface of the high-voltage line, and the rubber roller body 53 is driven to rotate by the motor 2 54. The friction between the rubber roller body 53 and the surface of the wire is used to correct the position of the suspension displacement component 2. The angle of the setting ensures that the test component 3 maintains the correct orientation and improves the data collection accuracy. After the correction is completed, the electric push rod 1 41 extends to make the rubber roller 44 contact the outer surface of the high-voltage line again to achieve circumferential friction limiting, and then the electric push rod 2 51 contracts and resets to separate the rubber roller body 53 from the high-voltage line. It can not only adjust the posture of the hanging shift component 2 during movement, but also be used for obstacle crossing posture adjustment. During the obstacle crossing process, it is necessary to temporarily release the clamping of a certain hanging shift component 2, and then cross the insulator, suspension clamp or other obstacles, and finally restore the clamping and continue to move forward. In this process, the entire component may cause the posture to change or rotate due to the adjustment of the support point. The angle of the entire component during the obstacle crossing is adjusted by the shift adjustment component 5 to ensure that the test component 3 can quickly return to the correct posture after the obstacle.
[0047] like Figure 3 、 Figure 6-Figure 8 As shown, one side of a pair of the support parts 21 is respectively connected to two line and surface cleaning components 6, and the line and surface cleaning components 6 include an arc seat 61 fixed to one side of the support part 21, a cavity 611 opened inside the arc seat 61, an opening 62 opened on the outer surface of the arc seat 61 and connected to the cavity 611, two driving rollers 64 rotatably connected to the inside of the cavity 611, a belt 67 sleeved on the outside of the two driving rollers 64, and a belt fixed on the outer surface of the belt 67. Brush 1 68, multiple arc-adjusting rollers 1 65 rotatably connected to the inner wall of the cavity 611 and whose outer surfaces are in contact with the inner wall of the belt 67, multiple arc-adjusting rollers 2 66 rotatably connected to the inner wall of the cavity 611 and whose outer surfaces are in contact with the outer surface of the belt 67, motor 3 63 fixedly connected to one side of the arc seat 1 61, and a scraper 69 fixedly connected to the inner wall of the cavity 611 for combing and scraping the bristles 1 68. The output shaft of motor 3 63 passes through the arc seat 1 61 and is fixedly connected to one end of one of the driving rollers 64.
[0048] One pair of the support parts 21 is respectively connected to two top and bottom cleaning parts 8, and the top and bottom cleaning parts 8 include a movable block 82 slidably connected to the support part 21 and a brush 2 83 fixed to one side of the movable block 82. One side of the two support parts 21 is respectively fixed with two electric push rods 3 81, and the telescopic ends of the two electric push rods 3 81 pass through the support part 21 and are respectively connected to one side of the two movable blocks 82. The two movable blocks 82 are respectively located above and below the high-voltage line.
[0049] The other side of one pair of the supporting parts 21 is respectively connected to two arc-shaped seats 2 , and the inner walls of the two arc-shaped seats 2 7 are fixedly connected to plastic scrapers 72 .
[0050] By adopting the above technical solution, when the three hanging and shifting components 2 move to the right on the high-voltage line, the rightmost hanging and shifting component 2 can clean the dust and impurities on the outer surface of the high-voltage line through the line and surface cleaning component 6, thereby increasing the friction between the extended hanging part 24, the rubber roller 44, the rubber roller body 53 and the outer surface of the high-voltage line, and at the same time, it can also prevent impurities from affecting the detection accuracy of the electrical detection component 3. The cleaning method is to drive one of the driving rollers 64 to rotate through the motor 3 63, and the driving roller 64 rotates to drive the belt 67 to rotate, and the brush 68 on the outside of the belt 67 cleans the left and right sides of the outer surface of the high-voltage line, and the arc adjustment roller 6 5 and the arc-adjusting roller 2 66 are designed to adjust the curvature of the belt 67 on the one hand, and to keep the belt 67 in a taut state on the other hand, so that the driving roller 64 can smoothly drive the belt 67 to rotate. The outer surface of the driving roller 64 can also be provided with anti-slip grooves to increase the friction in contact with the belt 67. The electric push rod 3 81 is extended to drive the movable block 82 to move from the inside of the support part 21 to the outside. When the upper and lower support parts 21 move to the top and bottom of the high-voltage line respectively, the bristles 83 can clean the upper and lower sides of the outer surface of the high-voltage line, and the impurities attached to the outside of the high-voltage line can be cleaned for a second time through the plastic scraper 72.
[0051] like Figure 3 As shown, the base 1 is internally connected with a plurality of conductive slip rings 13 consisting of a stator and a rotor rotatably connected to the stator, and the plurality of stators are fixedly connected to the base 1, and the plurality of rotors are respectively fixedly connected to one side of the plurality of support parts 21, and the base 1 is internally fixed with an energy storage part, and the energy storage part is electrically connected to the conductive slip ring 13 and the drive component 9, and the plurality of support parts 21 are internally provided with a plurality of wire grooves for the rotor output wires to pass through, and the rotor output wires are linearly connected to the electrical inspection component 3, the anti-sway stabilization component 4, the shift adjustment component 5, and the line surface cleaning component 6; a wire groove is provided inside the support part 21, and the power supply line of the conductive slip ring 13 is passed through the wire groove and is respectively connected to the electrical inspection component 3, the anti-sway stabilization component 4, the shift adjustment component 5, and the line surface cleaning component 6, so as to realize power supply to the electrical inspection component 3, the anti-sway stabilization component 4, the shift adjustment component 5, and the line surface cleaning component 6.
[0052] Instructions for use: In the initial state, the three pairs of support parts 21 in the three hanging and shifting components 2 are all in an inclined and outwardly expanded state (the two support parts 21 form a V shape). The base 1 is lifted by a drone, and the high-voltage line is located between the three pairs of support parts 21. The motor 4 91 works to drive the screw rod 92 to rotate, and the rotation of the screw rod 92 drives the seat body 93 to move downward. The downward movement of the seat body 93 drives the gear 95 to rotate through the tooth key 94, and the rotation of the gear 95 drives the support part 21 to rotate, so that the multiple support parts 21 are changed from an inclined state to a vertical state. The two support parts 21 in a pair are perpendicular to the base 1, and the extended hanging parts 24 inside the two support parts 21 can respectively contact the left and right sides of the upper surface of the high-voltage line, and the component is hung on the extended hanging part 24. On the high-voltage line, motor 1 25 drives the wheel body 23 and the extended hanging part 24 to rotate, and the rotation of the extended hanging part 24 drives the device to move axially on the high-voltage line. When the hanging shift component 2 moves on the high-voltage line, the leakage test of the high-voltage line is realized through the electric test component 3. When the electric push rod 1 41 works and extends and pushes the slide 1 42 to move toward the high-voltage line, the contact friction between the rubber roller 44 and the surface of the high-voltage line can provide a certain anti-torque effect, thereby limiting the circumferential rotation of the support part 21 and suppressing a certain degree of circumferential swing. By making the rubber roller body 53 contact with the outer surface of the high-voltage line, motor 2 54 drives the rubber roller body 53 to rotate, and the friction generated by the rubber roller body 53 and the surface of the wire can correct the angle of the device.
