Description

Technical Field

[0001] The present invention relates to the field of maintenance of high-voltage power lines, and more specifically, to a leakage and voltage detection component for maintenance of high-voltage power lines. Background Art

[0002] The leakage and voltage detection and maintenance of high-voltage power lines refer to the process of using voltage detection equipment to detect whether the line is energized and whether there is a leakage phenomenon during the maintenance of high-voltage transmission lines, so as to ensure the safety of maintenance work and the reliable operation of the power grid.

[0003] To solve the problem that the existing leakage and voltage detection and maintenance require manual climbing operations, the prior art (a Chinese invention patent application with the publication number CN112595883A) discloses a highly sensitive leakage and voltage detection component for maintenance of high-voltage power lines. By hardening the current-variant inside the extrusion ball, it pushes the push plug to move outward, causing the reminder board to unfold for leakage reminder. Although it can avoid manual climbing for voltage detection, this component needs to be installed outside the high-voltage line in advance. Since this component is not equipped with a moving structure, it cannot perform active axial movement on the high-voltage line. If you want to perform leakage and voltage detection on the entire length of the high-voltage line, the component needs to be completely covered and installed outside the high-voltage line, which will greatly increase the cost;

[0004] At the same time, in the prior art, drones are often used to mount inspection robots on high-voltage lines, and the inspection robots move on the high-voltage lines to complete the leakage detection of the high-voltage lines. For example, the semi-automated robot Expliner developed by the Japanese company HiBot, which can inspect high-voltage wires. This method of moving detection by robots has a lower cost compared to the leakage and voltage detection components disclosed in the above prior art. However, most of the current semi-automated robots used for inspecting high-voltage wires adopt a double-row hanging and moving structure, which needs to be hung on two horizontally aligned high-voltage wires to achieve movement. But in many scenarios, the high-voltage lines may be single or arranged irregularly (such as circular arrays, vertical arrangements, inclined distributions, etc.), and traditional robots cannot be used in these cases. Therefore, the applicability of this kind of robot is poor. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a leakage and voltage detection component for maintenance of high-voltage power lines.

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

[0007] A leakage and voltage detection component for maintenance of high-voltage power lines includes a base, and further includes three hanging and shifting components that are connected to the base and arranged in a collinear and equidistant manner;

[0008] The hanging and shifting assembly includes two support parts symmetrically arranged with one end rotatably connected inside the base, two plate bodies fixedly connected to the inner walls of the free ends of the two support parts respectively, two wheel bodies rotatably connected to one side of one plate body, one wheel body rotatably connected to one side of the other plate body, three extended hanging parts fixedly connected to one side of the three wheel bodies respectively, and a first motor fixedly connected to the other side of the two plate bodies to drive the wheel bodies and the extended hanging parts to rotate;

[0009] One side of a pair of the plate bodies is connected with an electric inspection assembly, and the electric inspection assembly includes an infrared thermal imager, a camera, an arc-shaped frame, an electric field sensor and a ranging sensor fixedly connected to the inner wall of the arc-shaped frame;

[0010] Inside the base, there are three driving assemblies for respectively driving one end of the three pairs of support parts to rotate.

[0011] Further, a plurality of first movable grooves are formed inside the base, one end of each of the plurality of support parts is respectively rotatably connected to the inner walls of the plurality of movable grooves, and limit blocks for restricting the rotation range of the support parts are fixedly connected to the inner walls of the plurality of movable grooves.

[0012] Further, the driving assembly includes two gears rotatably connected inside the base, a seat body slidably connected inside the base, tooth keys formed on both sides of the seat body and respectively meshing with the two gears, and a lead screw rotatably connected inside the base and screwed inside the seat body for driving the seat body to perform radial movement. One side of each of the two gears is fixedly connected to one side of the end of each of the two support parts. Three fourth motors are fixedly connected to the lower end of the base, and the output shafts of the three fourth motors penetrate into the base and are respectively fixedly connected to the lower ends of the three lead screws.

The multiple rubber roller bodies 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 bodies rotate. An inertial measurement part is fixedly connected to the lower end of the base.

[0016] Further, two wire and surface cleaning components are respectively connected to one side of a pair of the support parts. The wire and surface cleaning component includes an arc-shaped seat one fixedly connected to one side of the support part respectively, a cavity opened inside the arc-shaped seat one, an opening opened on the outer surface of the arc-shaped seat one and communicating with the cavity, two driving rollers rotatably connected inside the cavity, a belt sleeved outside the two driving rollers, a first brush fixedly connected to the outer surface of the belt, multiple first arc-adjusting rollers rotatably connected to the inner wall of the cavity and with the outer surface contacting the inner side wall of the belt, multiple second arc-adjusting rollers rotatably connected to the inner wall of the cavity and with the outer surface contacting the outer surface of the belt, a third motor fixedly connected to one side of the arc-shaped seat one, and a scraper fixedly connected to the inner wall of the cavity for scraping the first brush.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) This solution uses three hanging and shifting components arranged collinearly and equidistantly. Regardless of whether the high-voltage line is arranged in a single line or irregularly, the three hanging and shifting components can hang the live-line detection component on a single high-voltage line. By rotating the extending hanging part, the entire live-line detection component can be driven to move on the high-voltage line, and leakage detection of the high-voltage line can be carried out, with better applicability. At the same time, this application uses 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 the stability during the obstacle-crossing process is better.

[0022] (2) This solution is provided with an anti-sway and stability component. By pushing the sliding seat one towards the high-voltage line with the electric push rod one, the rubber roller is brought into contact with the outer surface of the high-voltage line. When the extending hanging part rotates and axially moves on the high-voltage line, the contact friction force between the rubber roller and the high-voltage line surface can provide a certain anti-torque effect, thereby restricting the circumferential rotation of the support part and suppressing a certain degree of circumferential swing, ensuring that the live-line detection component maintains a relatively stable orientation, improving the accuracy of image and signal acquisition, and enhancing the accuracy of live-line detection.

[0023] (3) This solution is provided with a shifting and adjusting component. By pushing the sliding seat two towards the high-voltage line with the electric push rod two, the rubber roller body is brought into contact with the outer surface of the high-voltage line. When the component rotates circumferentially by a small angle around the wire under the influence of wind during the moving process, the rubber roller body is driven to rotate, and the friction force generated between the rubber roller body and the wire surface is used to correct the angle of the live-line detection component, ensuring that the live-line detection component maintains the correct orientation and improving the data acquisition accuracy. At the same time, during the obstacle-crossing process, the live-line detection component usually needs to briefly release the clamping of a certain hanging and shifting component, then cross insulators, suspension clamps or other obstacles, and finally resume clamping and continue to move forward. During this process, the robot may change its posture or rotate due to the adjustment of the support points. By adjusting the angle of the live-line detection component during the obstacle-crossing process with the shifting and adjusting component, it is ensured that the live-line detection component can quickly return to the correct posture after passing the obstacle.

[0034] 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.

[0035] Please refer to Figures 1 to 8 , a leakage detection component 3 for power high-voltage line maintenance, including a base 1, and further including three hanging and shifting components 2 that are connected to the base 1 and arranged in a collinear and equidistant manner;

[0036] The hanging and shifting assembly 2 includes two supporting parts 21 that are symmetrically arranged with one end rotatably connected inside the base 1, two plate bodies 22 fixedly connected to the inner walls of the free ends of the two supporting parts 21 respectively, two wheel bodies 23 rotatably connected to one side of one plate body 22, one wheel body 23 rotatably connected to one side of the other plate body 22, three extending hanging parts 24 fixedly connected to one side of the three wheel bodies 23 respectively, and a first motor 25 fixedly connected to the other side of the two plate bodies 22 respectively to drive the wheel bodies 23 and the extending hanging parts 24 to rotate;

[0037] An electric inspection component 3 is connected to one side of a pair of the plate bodies 22, and the electric inspection component 3 includes an infrared thermal imager 31, a camera 32, an arc-shaped frame 33, an electric field sensor 34 and a ranging sensor 35 fixedly connected to the inner wall of the arc-shaped frame 33.

[0038] A plurality of first movable grooves 11 are formed inside the base 1, one end of each of the plurality of supporting parts 21 is rotatably connected to the inner wall of each of the plurality of movable grooves, and a limiting block 12 for restricting the rotation range of the supporting part 21 is fixedly connected to the inner wall of each of the plurality of movable grooves.

[0039] Three driving components 9 for respectively driving one end of three pairs of supporting parts 21 to rotate are connected inside the base 1. The driving component 9 includes two gears 95 rotatably connected inside the base 1, a seat body 93 slidably connected inside the base 1, tooth keys 94 formed on both sides of the seat body 93 and respectively meshed with the two gears 95, and a lead screw 92 rotatably connected inside the base 1 and screwed inside the seat body 93 for driving the seat body 93 to perform radial movement. One side of each of the two gears 95 is fixedly connected to one side of the end of each of the two supporting parts 21. Three fourth motors 91 are fixedly connected to the lower end of the base 1, and the output shafts of the three fourth motors 91 penetrate into the base 1 and are respectively fixedly connected to the lower ends of the three lead screws 92.

[0040] By adopting the above technical solution, in the initial state, the three pairs of supporting parts 21 in the three hanging and shifting components 2 are all in a state of being inclined and expanding outwards (the two supporting 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 supporting parts 21. The motor four 91 operates to drive the lead screw 92 to rotate. The rotation of the lead screw 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. The rotation of the gear 95 drives the supporting part 21 to rotate, so that the multiple supporting parts 21 change from an inclined state to a vertical state. The two supporting parts 21 in a pair are perpendicular to the base 1. The extending hanging parts 24 inside the two supporting 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 extending hanging part 24. The motor one 25 operates to drive the wheel body 23 and the extending hanging part 24 (which is composed of a cylinder fixed on one side of the wheel body 23 and a rubber sleeve fixed outside the cylinder) to rotate. The rotation of the extending hanging part 24 drives the device to axially move on the high-voltage line. When the hanging and shifting component 2 moves on the high-voltage line, the camera 32 can transmit the images collected outside the high-voltage line back to the control center in real time. Workers can judge whether there is damage or leakage in the high-voltage line by observing the images; at the same time, the infrared thermal imager 31 captures the temperature distribution of the high-voltage line to identify the overheated area. High-voltage leakage or poor contact will cause an increase in local resistance and abnormal heating. The detection of high-voltage line leakage is realized through the infrared thermal imager 31; the detection of the alternating electric field around the high-voltage line is realized through the electric field sensor 34. The electric field sensor 34 can be a capacitive sensor and an electromagnetic sensor. The capacitive sensor utilizes the coupling capacitance formed between the high-voltage line and the sensor electrode. When the high-voltage line is charged, its alternating electric field induces a weak alternating voltage on the sensor electrode. This weak signal is amplified by a high-impedance amplifier, thereby detecting the change in the electric field strength; the electromagnetic sensor is based on Faraday's law of electromagnetic induction. When an alternating magnetic field is generated by the alternating current in the high-voltage wire, a closed coil is placed in the magnetic field, and an electromotive force will be induced in the coil. Detecting this induced voltage or current can reflect whether the wire is charged and the magnitude of the current. The verification and detection of high-voltage line leakage are realized through the voltage or current;

[0041] When the present application moves on a high-voltage line and encounters obstacles such as cable gaskets and suspension clamps, the obstacle-crossing control actions are as follows: The motor four 91 at the rightmost end of the lower end of the base 1 operates 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 and outward-expanded state. At this time, the leftmost and middle hanging displacement assemblies 2 operate to drive the entire assembly to move to the right on the high-voltage line. The obstacle moves between the rightmost hanging displacement assembly 2 and the middle hanging displacement assembly 2. Then, the two rightmost support parts 21 are rotated to become vertical states and the extended hanging parts 24 are hung on the high-voltage line. The middle motor four 91 is controlled to operate so that the two middle support parts 21 change from a vertical state to an inclined and outward-expanded state. At this time, the leftmost and rightmost hanging displacement assemblies 2 operate to drive the entire assembly to move to the right on the high-voltage line. The obstacle moves between the leftmost hanging displacement assembly 2 and the middle hanging displacement assembly 2. Then, the two middle support parts 21 are rotated to become vertical states and the extended hanging parts 24 are hung on the high-voltage line. The leftmost motor four 91 is controlled to operate so that the two leftmost support parts 21 change from a vertical state to an inclined and outward-expanded state. At this time, the middle and rightmost hanging displacement assemblies 2 operate to drive the entire assembly to move to the right on the high-voltage line. The obstacle moves to the left of the leftmost hanging displacement assembly 2. Finally, the two leftmost support parts 21 are rotated to become vertical states and the extended hanging parts 24 are hung on the high-voltage line, completing the obstacle-crossing action. Since three hanging displacement assemblies 2 are adopted, when performing obstacle-crossing movement on a single high-voltage line, there are always two hanging displacement assemblies 2 hanging on the high-voltage line, providing at least two support points, and the stability during the obstacle-crossing process is relatively good.

[0042] As Figure 4 and Figure 5 shown, anti-sway and stabilizing components 4 are connected inside multiple said plate bodies 22, and the anti-sway and stabilizing components 4 include a first chute opened inside the plate body 22, a first sliding seat 42 slidably connected in the first chute, multiple movable seats 43 connected inside the first sliding seat 42, and multiple rubber rollers 44 rotatably connected to one side of the multiple movable seats 43. One side of the multiple said plate bodies 22 is fixedly connected with a first electric push rod 41, and the telescopic end of the first electric push rod 41 penetrates through the plate body 22 and is fixedly connected with one side of the first sliding seat 42. The multiple said rubber rollers 44 are in contact with the outer surface of the high-voltage line to form radial pressing, and there is relative rolling between the multiple rubber rollers 44 and the surface of the high-voltage line.

[0043] Multiple second movable slots 45 are opened inside the first sliding seat 42, and the multiple movable seats 43 are respectively slidably connected in the multiple second movable slots 45. Multiple springs 46 are respectively connected inside the multiple second movable slots 45, and two ends of the springs 46 are respectively connected with the inner wall of the second movable slot 45 and one side of the movable seat 43.

[0044] By adopting the above technical solution, during the process of the extension hanging part 24 rotating to drive the whole assembly to move on the high-voltage line, the first electric push rod 41 works to extend and push the first sliding seat 42 towards the high-voltage line. The movement of the first sliding seat 42 towards the high-voltage line enables a plurality of rubber rollers 44 to contact the outer surface of the high-voltage line. When the extension hanging part 24 axially moves on the high-voltage line, the contact friction force between the rubber rollers 44 and the surface of the high-voltage line can provide a certain anti-torque effect, thereby restricting the circumferential rotation of the support part 21, 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 live-line detection.

[0045] As Figure 4 and Figure 5 As shown, a displacement adjustment assembly 5 is further connected inside a plurality of the plate bodies 22. The displacement adjustment assembly 5 includes a second chute opened inside the plate body 22, a second sliding seat 52 slidably connected in the second chute, a rubber roller body 53 rotatably connected inside the second sliding seat 52, and a second motor 54 fixedly connected to one side of the second sliding seat 52. The output shaft of the second motor 54 is fixedly connected to one end of the rubber roller body 53. A second electric push rod 51 is further fixedly connected to one side of a plurality of the plate bodies 22, and the telescopic end of the second electric push rod 51 penetrates through the plate body 22 and is fixedly connected to one side of the second sliding seat 52. A plurality of the rubber roller bodies 53 contact the surface of the high-voltage line and form rolling friction with the surface of the high-voltage line when the rubber roller bodies 53 rotate. An inertial measurement unit 10 is fixedly connected to the lower end of the base 1.

[0046] By adopting the above technical solution, when the inertial measurement unit 10 (including an accelerometer + gyroscope + magnetometer, which can measure the rotation angle of the hanging displacement component around the wire in real time and is commonly used for attitude detection of unmanned aerial vehicles and robots, and belongs to mature existing technologies, which will not be elaborated here) detects that the angle of the base 1 is offset (the angle change generated by the circumferential movement of the entire component outside the high-voltage line under the influence of wind during the movement), at this time, the hanging displacement component 2 stops moving on the high-voltage line. At the same time, the first electric push rod 41 contracts to separate the rubber roller 44 from the outer surface of the high-voltage line. The second electric push rod 51 extends to push the second sliding seat 52 towards the high-voltage line, so that the rubber roller body 53 contacts the outer surface of the high-voltage line. The rubber roller body 53 is driven to rotate by the second motor 54, and the angle of the device is corrected by the frictional force generated between the rubber roller body 53 and the wire surface, ensuring that the live-line voltage detector assembly 3 maintains the correct orientation and improving the data acquisition accuracy. After the correction is completed, the first electric push rod 41 extends to make the rubber roller 44 contact the outer surface of the high-voltage line again to achieve circumferential frictional limit. Then the second electric push rod 51 contracts and resets to separate the rubber roller body 53 from the high-voltage line. It can not only adjust the attitude of the hanging displacement component 2 during the movement, but also be applied to obstacle-crossing attitude adjustment. During the obstacle-crossing process, it is necessary to briefly release the clamping of a certain hanging displacement component 2, then cross the insulator, suspension clamp or other obstacles, and finally resume the clamping and continue to move forward. During this process, the entire component may change its attitude or rotate due to the adjustment of the support point. The displacement adjustment component 5 adjusts the angle of the entire component during the obstacle-crossing process to ensure that the live-line voltage detector assembly 3 can quickly return to the correct attitude after passing the obstacle.

[0047] As Figure 3 , Figures 6 - 8 shown, on one side of a pair of the support parts 21, two wire surface cleaning components 6 are respectively connected. The wire surface cleaning component 6 includes an arc-shaped seat one 61 fixedly connected to one side of the support part 21, a cavity 611 opened inside the arc-shaped seat one 61, an opening 62 opened on the outer surface of the arc-shaped seat one 61 and communicating with the cavity 611, two driving rollers 64 rotatably connected inside the cavity 611, a belt 67 sleeved outside the two driving rollers 64, a first brush 68 fixedly connected to the outer surface of the belt 67, a plurality of first arc adjusting rollers 65 rotatably connected to the inner wall of the cavity 611 and the outer surface of which contacts the inner side wall of the belt 67, a plurality of second arc adjusting rollers 66 rotatably connected to the inner wall of the cavity 611 and the outer surface of which contacts the outer surface of the belt 67, a third motor 63 fixedly connected to one side of the arc-shaped seat one 61, and a scraper 69 fixedly connected to the inner wall of the cavity 611 for scraping the first brush 68. The output shaft of the third motor 63 penetrates the arc-shaped seat one 61 and is fixedly connected to one end of one of the driving rollers 64.

[0048] Two top and bottom cleaning parts 8 are respectively connected to the inside of a pair of the supporting parts 21. The top and bottom cleaning part 8 includes a movable block 82 slidably connected in the supporting part 21 and a second brush 83 fixedly connected to one side of the movable block 82. Two electric push rods three 81 are respectively fixedly connected to one side of the two supporting parts 21, and the telescopic ends of the two electric push rods three 81 penetrate through the supporting parts 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] Two arc seats two 7 are respectively connected to the other side of a pair of the supporting parts 21, and plastic scrapers 72 are fixedly connected to the inner walls of the two arc seats two 7.

[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 wire 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. At the same time, it can also prevent impurities from affecting the detection accuracy of the electric inspection component 3. The cleaning method is to drive one of the driving rollers 64 to rotate by the motor three 63. The rotation of the driving roller 64 drives the belt 67 to rotate. The outer surface of the belt 67 is brushed by the first brush 68 on the left and right sides of the outer surface of the high-voltage line. The design of the arc adjusting roller one 65 and the arc adjusting roller two 66 is used to adjust the arc 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 drive the belt 67 to rotate smoothly. The outer surface of the driving roller 64 can also be provided with anti-slip lines to improve the friction with the belt 67. When the electric push rod three 81 works and extends, it can drive the movable block 82 to move outwards from the supporting part 21. When the upper and lower two supporting parts 21 move to the upper and lower sides of the high-voltage line respectively, the second brush 83 can brush the upper and lower sides of the outer surface of the high-voltage line, and the plastic scraper 72 can scrape the impurities attached to the outside of the high-voltage line for the second time.

[0051] As Figure 3 shown, a plurality of slip rings 13 composed of a stator and a rotor rotatably connected to the stator are connected to the inside of the base 1. A plurality of stators are fixedly connected to the inside of the base 1, and a plurality of rotors are respectively fixedly connected to one side of the plurality of supporting parts 21. An energy storage part is fixedly connected to the inside of the base 1, and the energy storage part is electrically connected to the slip rings 13 and the driving component 9. A plurality of wire grooves for the rotor leads to pass through are formed in the plurality of supporting parts 21, and the rotor leads are linearly connected to the electric inspection component 3, the anti-sway and stability component 4, the displacement adjustment component 5, and the wire and surface cleaning component 6; wire grooves are formed in the supporting part 21, and the power supply wires of the slip rings 13 pass through the wire grooves and are respectively connected to the electric inspection component 3, the anti-sway and stability component 4, the displacement adjustment component 5, and the wire and surface cleaning component 6 to realize the power supply to the electric inspection component 3, the anti-sway and stability component 4, the displacement adjustment component 5, and the wire and surface cleaning component 6.

[0052] Usage method: In the initial state, the three pairs of supporting parts 21 in the three hanging and shifting components 2 are all in a state of being inclined and expanding outwards (the two supporting 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 supporting parts 21. The motor four 91 operates to drive the lead screw 92 to rotate. The rotation of the lead screw 92 drives the seat body 93 to move downwards. The downward movement of the seat body 93 drives the gear 95 to rotate through the tooth key 94. The rotation of the gear 95 drives the supporting part 21 to rotate, so that the multiple supporting parts 21 change from an inclined state to a vertical state. The two supporting parts 21 in a pair are perpendicular to the base 1. The extending hanging parts 24 inside the two supporting 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 extending hanging part 24. The motor one 25 operates to drive the wheel body 23 and the extending hanging part 24 to rotate. The rotation of the extending hanging part 24 drives the device to axially move on the high-voltage line. When the hanging and shifting component 2 moves on the high-voltage line, the leakage and power-on detection of the high-voltage line are realized through the power-on inspection component 3. When the electric push rod one 41 operates to extend and push the sliding seat one 42 towards the high-voltage line, the contact friction force between the rubber roller 44 and the surface of the high-voltage line can provide a certain anti-torque effect, thereby restricting the circumferential rotation of the supporting part 21 and suppressing a certain degree of circumferential swing. By making the rubber roller body 53 contact the outer surface of the high-voltage line, the motor two 54 drives the rubber roller body 53 to rotate. The friction force generated by the rubber roller body 53 and the surface of the wire can correct the angle of the device.
