[0002] In the operation and maintenance of power systems, testing power lines and electrical equipment and hanging and removing grounding wires are key links to ensure the safety of operators and prevent electrical accidents caused by misoperation. The current process of testing power and hanging and removing grounding wires is highly dependent on manual climbing or using a climbing vehicle. For high-voltage transmission lines, the transmission towers are high and the geographical environment in which they are built is complex and diverse, making manual climbing difficult and risky. During each operation, operators need to carry heavy power testing and grounding equipment and climb along the towers to the designated location. The physical energy consumption is huge and the operation time is restricted by the physical strength and proficiency of the personnel. The operation is cumbersome and complicated. Accurately installing wire clamps and tightening bolts at high altitudes requires extremely high skills and concentration of operators. Once the grounding is poor, the equipment will not be able to effectively discharge the current when it leaks, which may lead to serious consequences such as damage to power equipment and electric shock casualties. As the scale of the power system continues to expand, the line mileage continues to grow and the distribution becomes more and more extensive, the operation and maintenance workload is growing rapidly, and the efficiency of traditional manual methods is increasingly difficult to meet the needs of efficient operation and maintenance.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, the present invention provides a device for assisting the hanging and removing of ground wires for electric testing of unmanned aerial vehicles, comprising an unmanned aerial vehicle body 1 and a hook 11 installed on the unmanned aerial vehicle body 1, and further comprising: a non-contact electric tester 2 and a communication module 3, both of which are installed on the unmanned aerial vehicle body 1, wherein the communication module 3 is used to transmit the data signal of the non-contact electric tester 2 to a receiving terminal of a ground operator; a mounting frame assembly 4, which is mounted below the unmanned aerial vehicle body 1 through the hook 11; a ground wire assembly 5, which is arranged on the mounting frame assembly 4; a guide assembly 8, which is arranged inside the frame 41 and is used to retract the mounting frame assembly 4 when it is lifted;

[0037] The mounting frame assembly 4 includes a frame body 41, a hanging rod 42 is movably connected inside the frame body 41, a hook 2 43 mounted on the bottom end of the hook 1 11 is fixedly connected to the top of the hanging rod 42, an elastic telescopic rod 44 is hinged inside the frame body 41, a pressing block 45 movably connected to the frame body 41 is fixedly connected to the top of the elastic telescopic rod 44, and the bottom end of the elastic telescopic rod 44 is hinged to the hanging rod 42;

[0038] The grounding wire assembly 5 includes a slider 51 movably connected to the inside of the frame 41, a guide rod 53 is hinged on the slider 51, and the hinge is a rotating shaft 532, and a protruding rod 533 is fixedly connected to one end of the slider 51;

[0039] A guide groove 411 is formed inside the frame 41, and the protruding rod 533 can slide in the guide groove 411. The bottom of the guide groove 411 is arc-shaped, and the arc-shaped part takes the rotating shaft 532 as the center.

[0040] A cable 6 is movably connected inside the frame 41, one end of the cable 6 extends into the guide rod 53 and extends out from one end of the guide rod 53 and is fixedly connected with a connecting fastener 61, and the other end of the cable 6 extends from one end of the frame 41 to the ground line-laying end and is adjusted by the operator;

[0041] The frame 41 is in an expanded state from the top to the bottom ends, and a depression facing upwards and used to hang on the cable is provided in the middle thereof, and the frame 41 is made of metal material as a whole; the pressing block 45 and the guide rod 53 can both rotate and be retracted into the frame 41;

[0042] A guide wheel three 531 is also movably connected to the guide rod 53, a guide wheel two 413 is also movably installed inside the frame 41, a motor 7 is also installed on the frame 41, and the output shaft end of the motor 7 passes through the frame 41; the cable 6 is connected around the output end of the motor 7, the guide wheel two 413, the rotating shaft 532 and the guide wheel three 531; a battery 71 for supplying power to the motor 7 is also arranged inside the frame 41.

[0043] By adopting the above scheme, the drone body 1 is operated to drive the hook 11 to lift the mounting frame assembly 4 as a whole. The frame 41 is kept still by its own gravity, and the hook 2 43 drives the hanging rod 42 upward, so that the bottom end of the elastic telescopic rod 44 moves upward and rotates, and the top end of the elastic telescopic rod 44 drives the pressing block 45 to rotate and shrink into the frame 41. When the frame 41 is above the power transmission cable, the drone body 1 drives the frame 41 downward. When the cable supports the depression in the middle of the frame 41, the drone body 1 releases the suspension of the hook 2 43, and then The elastic force of the elastic telescopic rod 44 resets the elastic telescopic rod 44 itself, the pressure block 45 and the hanging rod 42, and the reset of the pressure block 45 will clamp the power transmission cable between the frame 41 and the pressure block 45, and then the running motor 7 drives the cable 6 to release the line, and at the same time, the end of the connecting fastener 61 goes down to connect the grounding wire with the connecting fastener 61, and then the operator pulls the other end of the cable 6 to lift the connecting fastener 61 and the grounding wire and contact the end of the guide rod 53, thereby solving the problem that it is cumbersome and unsafe to hang the grounding wire on the power transmission line by manual climbing.

[0044] It is worth noting that since the bottom of the guide groove 411 is arc-shaped and the arc-shaped part is centered on the rotating shaft 532, when the frame 41 is hung on the transmission line, the transmission cable will first squeeze the guide rod 53 to retract it into the frame 41, thereby preventing the frame 41 from being blocked by the guide rod 53 when it is hung on the transmission cable.

[0045] like Figure 3 , Figure 5 and Figure 7 As shown, the top of the hanging rod 42 extends to the top of the frame 41 and is curved; when the hanging rod 42 goes up to the top, the second hook 43 is at the symmetry axis of the frame 41;

[0046] By adopting the above scheme, when the hanging rod 42 goes up to the top, since the hook 2 43 is located at the symmetry axis part of the frame 41, it can be ensured that when the hook 11 lifts the frame 41 through the hook 2 43 and the hanging rod 42, the opening at the frame 41 is stably facing downward, so that the frame 41 can be subsequently hung on the power cable.

[0047] like Figure 4-Figure 8 As shown, a spring combination rod 52 is movably sleeved on the slider 51, and both ends of the rod body of the spring combination rod 52 are fixedly connected to the frame body 41;

[0048] One end of the spring portion of the spring combination rod 52 is fixedly connected to the frame 41, and the other end is used to support the slider 51 to maintain a downward trend;

[0049] By adopting the above scheme, when the operator pulls the cable 6 to drive the connecting fastener 61 and the grounding wire upward, after the grounding wire contacts the guide rod 53, continuing to pull the cable 6 will cause the slider 51 and the guide rod 53 to move upward and cause the spring part on the spring combination rod 52 to be compressed. Furthermore, when the cable 6 extends to one end of the ground and is fixed, and the transmission cable shakes, it can ensure that the grounding wire can stably contact the guide rod 53.

[0050] like Figure 6-Figure 8 As shown, the guide assembly 8 includes a guide frame 81 movably connected to the inside of the frame body 41, a tension spring assembly block 82 with a width smaller than the guide frame 81 is fixedly connected to the top of the guide frame 81, the tension spring assembly block 82 is elastically connected to the inside of the frame body 41, and the tension spring assembly block 82 has an upward trend under the action of its own tension;

[0051] The bottom sides of the hanging rod 42 are also fixedly connected with a fixing block 421, and the frame body 41 is also movably connected with a guide wheel 412; the guide wheel 412 is externally connected with a pull rope 422 with two ends respectively connected with the fixing block 421 and the tension spring combination block 82;

[0052] A groove 811 is further provided on the side of the guide frame 81 away from the guide rod 53; the guide frame 81 is in a straight line when located inside the frame body 41, and the tension spring assembly block 82 can bend outward with the groove 811 as the axis when it moves to the outside of the frame body 41;

[0053] By adopting the above scheme, when the hanging rod 42 goes up, it will also drive the fixed block 421 and one end of the pull rope 422 to go up. At the same time, the other end of the pull rope 422 will pull the guide frame 81 downward through the tension spring combination block 82, so that the guide frame 81 expands outward, thereby expanding the coverage of the bottom of the frame 41, thereby ensuring that the frame 41 can be stably hung on the power transmission cable.

[0054] like Figure 3 , Figure 4 and Figure 6-Figure 8 As shown, when the tension spring assembly block 82 moves downward, the protruding rod 533 can move along the guide groove 411 and the guide rod 53 can be rotated and retracted into the frame body 41;

[0055] By adopting the above scheme, when the tension spring combination block 82 moves downward, it can also push the protruding rod 533 to move along the arc-shaped part at the bottom of the guide groove 411, so that the guide rod 53 rotates and retracts into the frame 41, thereby ensuring that the subsequent transmission line can stably hang along the bottom of the frame 41 on the recessed part in the middle of the frame 41.

[0056] The working principle and use process of the present invention:

[0057] During the electricity test, the operator controls the drone body 1 to fly above the power transmission cable, and uses the non-contact tester 2 to perform inductive electricity test on the power transmission cable and detect the voltage level, and then transmits the data to the handheld terminal of the ground operator through the communication module 3;

[0058] When hanging the ground wire, the drone body 1 lifts the mounting frame assembly 4 as a whole through the hook 11. In this process, the frame 41 will remain stationary due to its own gravity, and the hook 2 43 will drive the hanging rod 42 to move upward relative to the frame 41, so that the bottom end of the elastic telescopic rod 44 moves upward and rotates, and the top end of the elastic telescopic rod 44 drives the pressing block 45 to rotate and shrink into the frame 41. When the frame 41 is above the power transmission cable, the drone body 1 drives the frame 41 downward, and when the cable supports the depression in the middle of the frame 41, the drone The main body 1 releases the suspension of the hook 2 43, and then the elastic force of the elastic telescopic rod 44 resets the elastic telescopic rod 44 itself, the pressure block 45 and the hanging rod 42, and the reset of the pressure block 45 will clamp the power transmission cable between the frame 41 and the pressure block 45, and then the running motor 7 drives the cable 6 to release the line, and at the same time, the end of the connecting fastener 61 goes down to fasten the grounding wire with the connecting fastener 61, and then the operator pulls the other end of the cable 6 to lift the connecting fastener 61 and the grounding wire and contact them with the end of the guide rod 53, thereby completing the grounding operation of the power transmission line;

[0059] When the hanging rod 42 moves upward, it will also drive the fixed block 421 and one end of the pull rope 422 to move upward. At the same time, the other end of the pull rope 422 will pull the guide frame 81 downward through the tension spring combination block 82, so that the guide frame 81 expands outward, thereby increasing the coverage of the bottom of the frame 41, thereby ensuring that the frame 41 can be stably hung on the power transmission cable;

[0060] When the tension spring assembly block 82 moves downward, it can also push the protruding rod 533 to move along the arc-shaped part at the bottom of the guide groove 411, so that the guide rod 53 rotates and retracts into the frame 41, thereby ensuring that the subsequent transmission line can stably hang along the bottom of the frame 41 on the recessed part in the middle of the frame 41.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
