Description

Technical Field

[0001] The present invention relates to the technical field of power grid detection, and in particular to a multi-parameter interactive power grid line nondestructive detection device and method. Background Art

[0002] The multi-parameter interactive power grid is a complex power system, which involves the interaction and influence of multiple parameters. These parameters include voltage, current, power, frequency, phase difference, etc., which have mutual influence and action. In the multi-parameter interactive power grid, there are interactions and influences between different parameters, such as the relationship between voltage and current, the relationship between power and frequency, etc. The changes in these parameters will affect the performance and stability of the power grid. In order to ensure the stable operation and reliability of the multi-parameter interactive power grid, it is necessary to inspect it frequently. Through inspection, problems and faults in the power grid can be discovered in time to avoid potential risks and hidden dangers. At the same time, inspection can also evaluate and predict the operating status of the power grid, providing a basis for subsequent maintenance and improvement. The four-split conductor is a combination of high-voltage transmission lines, in which a complete conductor is split into four thinner conductors. This combination can reduce the skin effect of corona and current, reduce the reactance of the line, and thus improve the transmission efficiency. Four-split conductors are usually used in high-voltage transmission lines of voltage levels such as 220 kV, 330 kV and 500 kV. In the inspection process of four-split conductors, walking robots are generally used instead of manual inspections. Wheeled or crawler robots can be used, equipped with high-definition cameras, sensors and other equipment, to move along the conductors, collect images, temperature, vibration and other information of the conductors in real time, and transmit the data back to the control center for analysis. Through the autonomous navigation and intelligent control of the robot, unmanned, all-weather, and all-round inspections can be achieved, improving the efficiency and accuracy of the inspections.

[0003] During the existing walking robot detection process, generally only one wire is detected separately. For the detection of four-split wires, it is necessary to place the walking robot on another wire for detection after completing the detection of one wire. For short-distance wire detection, the placement position of the walking robot needs to be changed frequently. For long-distance detection, the walking distance is longer, which is more time-consuming and reduces the practicality of the walking robot. Summary of the invention

[0004] The present invention provides a multi-parameter interactive power grid line nondestructive testing device and method, which has the beneficial effect of facilitating the detection of four-split conductors, and solves the problem mentioned in the above background technology that the existing walking robot generally only detects one conductor separately during the detection process. For the detection of four-split conductors, it is necessary to place the walking robot on another conductor for detection after completing the detection of one conductor. For the detection of short-distance conductors, it is necessary to frequently change the placement position of the walking robot. For the detection of long-distance conductors, the walking distance is longer, which is more time-consuming and reduces the practicality of the walking robot.

[0033] The lifting mechanism includes a drone body 401, a first motor 402 is symmetrically embedded at the bottom of the drone body 401, and a hook 403 is fixedly connected to the output end of the first motor 402. After the first motor 402 rotates, it can drive the hook 403 to swing left and right with the output end of the first motor 402 as the center, and a lifting groove 404 is opened on the top of the horizontal plate 3 for cooperating with the hook 403.

[0034] The walking mechanism includes a second motor 701, the output end of the second motor 701 is fixedly connected to a walking wheel 702, and the outer side of the walking wheel 702 is provided with an anti-slip groove 703. After the second motor 701 is started, it drives the walking wheel 702 to rotate. After the walking wheel 702 rotates on the lightning conductor in the four-split conductor, it drives the frame body 1 to walk on the lightning conductor.

[0035] The side detection mechanism includes a first side lens 801, a second side lens 802 is fixedly connected to a position on one side of the sliding plate 5 opposite to the first side lens 801, the first side lens 801 and the second side lens 802 are located on both sides of the side wires in the four-split wires, and the two lenses are symmetrically arranged on both sides of the wires, a first extension plate 803 is fixedly connected to the top of one side of the sliding plate 5, a third side lens 804 is fixedly connected to one side of the first extension plate 803, and the third side lens 804 is located above the side wires, the inner side of the rack body 1 is rotatably connected to the second extension plate 805 through a reset shaft, a fourth side lens 806 is fixedly connected to one side of the second extension plate 805, and the fourth side lens 806 is located below the side wires, and the reset shaft is usually composed of two parts: a fixed part and a rotatable part. When the rotating part is rotated, it can automatically return to its original position under the action of an internal spring, that is, reset.

[0036] The side detection mechanism can conduct a comprehensive and detailed inspection of the leftmost and rightmost wires among the four split wires, and can detect problems with the wires more intuitively.

[0037] The bottom detection mechanism includes a first bottom lens 901, which is located between the lightning protection wire and the bottom conductor, and detects the bottom of the lightning protection wire and the top of the bottom conductor respectively. The bottom of the other side of the sliding plate 5 is fixedly connected with a second bottom lens 902, and the second bottom lens 902 is located on both sides of the bottom conductor in the four-split conductor. The end of the rack body 1 is rotatably connected with a bottom plate 903 through a reset shaft. A support plate 904 is provided at the bottom of the bottom plate 903, and one side of the support plate 904 is fixedly connected to the rack body 1. One end of the bottom plate 903 is slidably connected with a third bottom lens 905, and the third bottom lens 905 is located at the bottom of the bottom conductor. One end of the third bottom lens 905 extends to the inside of the bottom plate 903 and is fixedly connected with a first connecting plate 906. Both sides of the first connecting plate 906 are fixedly connected with second connecting plates 907.

[0038] The bottom detection mechanism can perform a full range of detection on the bottom conductor of the four-split conductor, and detect the lightning conductor at the same time. The lightning conductor is relatively simple in structure and installation, and does not directly carry current, so it usually has fewer problems. The other three conductors need to carry current, and their structure and material requirements are relatively high. They are also affected by complex factors such as mechanical force and electric force, and are prone to problems such as wear and tear, broken strands, etc. Therefore, the inspection and maintenance of these three conductors need to be more meticulous.

[0039] A first tension spring 908 is fixedly connected to one side of the second connecting plate 907, one end of the first tension spring 908 is fixedly connected to the inner wall of the bottom plate 903, a fixed seat 909 is fixedly connected to the bottom of the sliding plate 5, a push plate 910 is fixedly connected to the bottom of the fixed seat 909, and the push plate 910 is in contact with the first connecting plate 906.

[0040] Hoisting frame: After starting the drone body 401, the frame body 1 can be hoisted into the air through the cooperation of the hook 403 at the bottom of the drone body 401 and the cross plate 3 at the top of the frame body 1, and the drone body 401 is controlled to make the frame body 1 fly to the top of the four-split conductor, and slowly fall on the top of the four-split conductor, so that the walking wheel 702 of the walking mechanism contacts the lightning conductor. After contact, the first motor 402 reverses to control the hook 403 to rotate, and then controls the drone body 401 to leave from the top of the cross plate 3, so that the frame body 1 completely falls on the four-split conductor;

[0041] Walking inspection: After starting the second motor 701, the walking wheel 702 is driven to rotate, thereby controlling the rack body 1 to walk on the lightning protection line. While the rack body 1 is walking, the lenses in the side detection mechanism and the bottom detection mechanism collect images of the four-split conductors for detection.

[0042] Lens extension and retraction: When the frame body 1 is placed on the four-split wire by the drone body 401, the frame body 1 will slowly fall. During the falling process of the frame body 1, the bottom plate 903 contacts the side wires of the four-split wire and then swings upward. After the frame body 1 completely falls on the four-split wire, the bottom plate 903 is reset downward and contacts the support plate 904 through the side wires under the action of gravity. As the drone body 401 separates from the cross plate 3, the sliding plate 5 moves downward. During the downward movement of the sliding plate 5, the first connecting plate 906 is pushed to move by the push plate 910. The third bottom lens 905 fixedly connected to the first connecting plate 906 extends from the bottom plate 903 under the indirect push of the push plate 910, so that the third bottom lens 905 can capture images of the bottommost wire of the four-split wire, and protect the third bottom lens 905 during the falling process of the frame body 1 on the four-split wire.

[0043] Embodiment 2

[0044] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 7 The inner side of the fixed plate 6 is rotatably connected to an adjusting plate 10 via a reset shaft, one side of the adjusting plate 10 is rotatably connected to an auxiliary wheel 11 via a shaft, the end of the adjusting plate 10 is fixedly connected to a gear 12, one side of the sliding plate 5 is fixedly connected to a tooth 13 used to cooperate with the gear 12, the tooth 13 is meshed with the gear 12, and a space is opened inside the fixed plate 6 for the sliding plate 5 to drive the tooth 13 to move.

[0045] Auxiliary clamping: the frame body 1 is placed on the four-split conductor. After the drone body 401 is separated from the cross plate 3, the cross plate 3 moves downward under the action of gravity and the second tension spring 15, thereby pushing the sliding plate 5 to move downward. When the sliding plate 5 moves downward, it slides relative to the fixed plate 6. Then, the adjustment plate 10 rotatably connected to the fixed plate 6 engages with the gear 12 and the teeth 13, and swings upward during the downward movement of the sliding plate 5, so that the auxiliary wheel 11 contacts the lightning conductor from the bottom of the lightning conductor upward, and clamps the lightning conductor after cooperating with the walking wheel 702. After the lightning conductor is clamped, the walking wheel 702 is in closer contact with the lightning conductor, so that the frame body 1 will not slip when walking on the lightning conductor.

[0046] A storage groove 14 is provided at the bottom of the horizontal plate 3, and a second tension spring 15 is sleeved on the outer side of the vertical column 2. One end of the second tension spring 15 is fixedly connected to the inner wall of the storage groove 14, and the other end of the second tension spring 15 is fixedly connected to the top of the frame body 1. A baffle plate 16 is fixedly connected to the top of the vertical column 2. A baffle groove 17 that matches the gap with the baffle plate 16 is provided on the top of the horizontal plate 3. A first extension groove 18 used in conjunction with the first extension plate 803 is provided on the inner side of the frame body 1, and a second extension groove 19 used in conjunction with the second extension plate 805 is provided on the side wall of the frame body 1.

[0047] The other end of the bottom plate 903 is fixedly connected to the first contact plate 20, and the frame body 1 and the support plate 904 are provided with a space for the first contact plate 20 to move. The interior of the frame body 1 is rotatably connected to the transmission plate 21 through a rotating shaft, and the rotating shaft is located in the middle part of the transmission plate 21. The end of the first extension plate 803 is provided with a second contact plate 22, and one end of the second contact plate 22 extends to the interior of the frame body 1 and contacts with the transmission plate 21, and the second contact plate 22 is slidably connected to the frame body 1.

[0048] Contact fixation: When the bottom plate 903 rotates upward, the first contact plate 20 will be driven to rotate. The first contact plate 20 swings upward and moves away from the transmission plate 21. After the bottom plate 903 rotates downward and resets, the transmission plate 21 is pushed to rotate by the first contact plate 20, and the transmission plate 21 pushes the second contact plate 22 to move toward the side close to the first extension plate 803. When the bottom plate 903 is completely reset, the second contact plate 22 contacts the first extension plate 803, and the position of the bottom plate 903 is limited by the sliding plate 5 and the push plate 910. Subsequently, when the rack body 1 moves on the lightning protection line, the contact between the second contact plate 22 and the first extension plate 803 can eliminate the gap between the first extension plate 803 and the rack body 1, making the first extension plate 803 more stable, and the third side lens 804 fixed on one side will not shake during the movement of the rack body 1, thereby improving the clarity of the image captured by the third side lens 804.

[0049] This embodiment also discloses a multi-parameter interactive power grid line nondestructive testing method:

[0050] The following steps are also included

[0051] S1. The frame body 1 is hoisted above the four-split conductor by the hoisting mechanism, and then the frame body 1 is controlled to fall on the four-split conductor. When the hoisting mechanism is separated from the frame body 1, the cross plate 3 is reset under the tension of the second tension spring 15, pushing the sliding plate 5 to move downward. While the sliding plate 5 moves, the auxiliary wheel 11 is pushed upward to swing, and the lightning arrester is clamped after cooperating with the walking wheel 702, so as to facilitate the walking inspection of the frame body 1;

[0052] S2. When the rack body 1 falls, the bottom plate 903, the first extension plate 803 and the second extension plate 805 which are rotatably connected inside the rack body 1 are pushed upward by the wires, so that the rack body 1 can fall smoothly. After the rack body 1 falls completely, the bottom plate 903, the first extension plate 803 and the second extension plate 805 are rotated and reset;

[0053] S3, the rotation of the bottom plate 903 will push the third bottom lens 905 to shrink and extend after passing through the position of the wire. At the same time, the rotation of the bottom plate 903 will push the second contact plate 22 to shrink and contact the first extension plate 803, pressing the first extension plate 803 to prevent the first extension plate 803 from shaking when the rack body 1 moves.
