Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage transmission line detection, and in particular is an unmanned aerial vehicle tension insulator detection zero value device. Background Art

[0002] In the power system, insulators are an important part of the transmission line, and their performance is directly related to the safe operation of the line. However, in the long-term operation process, the resistance of insulators may decrease due to factors such as aging and pollution, becoming low-value or zero-value insulators, which in turn affects the insulation performance of the insulator string and even induces breakdown discharge accidents. Therefore, regular inspection of insulators and timely detection and replacement of low-value or zero-value insulators are of great significance to ensure the safe operation of the power system.

[0003] At present, the research and application of drone-mounted tension insulator zero-value detection devices have made certain progress. For example, a variety of drone-mounted insulator detection devices have been developed. These devices usually use electric field detection, infrared thermal imaging and other technical means to detect the performance of insulators. Among them, the electric field detection technology can determine the resistance state of the insulator by measuring the spatial electric field distribution around the insulator, and then identify low-value or zero-value insulators. In addition, some devices also use automated detection technology, such as rolling detection probes, robotic arm assemblies, etc., which can realize automatic detection of insulators. These devices usually have the advantages of high precision, high efficiency, and high safety, which can greatly reduce the workload of detection personnel and improve detection efficiency and quality.

[0004] Although the UAV tension insulator detection zero-value device has achieved certain application results in power inspection and significantly improved the detection efficiency and safety, it still faces some key technical challenges, especially in the process of the UAV deploying the detection device to the insulator to be inspected by hooking, and flying back to hook the device and transfer it to the next inspection point after the inspection is completed. There are significant safety hazards. Since insulators are usually built at a higher position above the ground, when the UAV is operated under strong winds or other external forces, the simple hook and hook rope connection device is easy to fall off. This falling off will not only cause the detection device to fall from a high altitude, causing equipment damage and financial losses, but is more likely to accidentally injure the staff below, causing serious personal injury accidents. Therefore, how to ensure a stable connection between the UAV and the detection device to prevent it from falling off in a complex environment has become a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0020] 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.

[0021] like Figures 1 to 9 As shown, the present invention provides a zero-value detection device for an unmanned aerial vehicle tension insulator, comprising a detection device 1, a unmanned aerial vehicle 9 is arranged above the detection device 1, a hook 901 is fixedly installed on the bottom of the unmanned aerial vehicle 9, two fixed plates 101 and two mounting blocks 5 are fixedly installed on the inner wall of the bottom of the detection device 1, the two fixed plates 101 are located in the middle of the two mounting blocks 5, and a rotating rod 1 3 and two rotating rods 2 4 are rotatably installed on the side of the two fixed plates 101 that are close to each other, and the two ends of the rotating rod 1 3 and the two rotating rods 2 4 respectively pass through the two fixed plates 101, and two tooth columns 1 302 are fixedly sleeved on the outer wall of the rotating rod 1 3, and two tooth columns 2 401 and a winding rod 402 are fixedly sleeved on the outer walls of the two rotating rods 2 4, and steel wires 403 are wound around the outer walls of the two winding rods 402.

[0022] By rotating the rotating rod 1 3, the rotating rod 1 3 drives the two tooth columns 1 302 to rotate, and through the meshing of the tooth column 1 302 with the tooth groove 601, and the meshing of the tooth groove 601 with the tooth column 2 401, the two tooth grooves 601 are driven to rotate, and the two tooth grooves 601 drive the corresponding rotating rod 2 4. The rotating rod 2 4 not only serves as a transmission component, but also undertakes the support and driving task of the winding rod 402. The winding rod 402 rotates with the rotation of the rotating rod 2 4, thereby realizing the tightening and loosening of the steel wire 403.

[0023] like Figures 8 to 9As shown, threads 303 are respectively provided on the outer walls of both sides of the rotating rod 3, and the thread directions of the two threads 303 are opposite. Two clamping blocks 7 are respectively threadedly sleeved on the outer walls of the two threads 303, and a fixed plate 701 is fixedly installed on the side where the two clamping blocks 7 are close to each other, and an arc-shaped clamping half circle 702 is fixedly installed on the side where the two fixed plates 701 are close to each other.

[0024] Because the thread directions of the two threads 303 are opposite, the two clamping blocks 7 can be respectively threadedly mounted on the two sides of the rotating rod 3, and the rotating rod 3 can be rotated to realize the simultaneous movement of the clamping blocks 7 toward or away from each other. The two clamping blocks 7 are respectively fixedly installed with fixed plates 701 on the sides close to each other. These fixed plates further enhance the stability and structural strength of the clamping blocks. The arc-shaped clamping half circle 702 can fit tightly together when the clamping block 7 moves to form a complete circular clamping structure, thereby achieving a stable clamping of the hook 901.

[0025] like Figures 4 to 6 As shown, a motor 2 is fixedly mounted on the bottom inner wall of the detection device 1, a bevel gear 201 is fixedly sleeved on the output shaft of the motor 2, a bevel gear 2 301 is fixedly sleeved on the middle outer wall of the rotating rod 1 3, and the bevel gear 2 301 is meshed with the bevel gear 201.

[0026] Driven by the motor 2, the bevel gear 201 can rotate smoothly, thereby driving the meshing bevel gear 2 301 and the rotating rod 1 3 to rotate together. The transmission method not only has high transmission efficiency, but also can ensure the stability and accuracy of rotation, providing reliable power guarantee for subsequent detection work.

[0027] like Figures 4 to 6 As shown, two limiting grooves 502 are respectively formed on the sides of the two mounting blocks 5 that are close to each other, and the two limiting grooves 502 are staggered in the vertical direction.

[0028] The staggered limiting grooves provide the device with a larger adjustment range and flexibility, so that when the tooth grooves 601 on the two rectangular blocks 6 are engaged with the tooth column 401, the movement of the two rectangular blocks 6 is not affected by each other, ensuring smooth transmission.

[0029] like Figures 4 to 6 As shown, rectangular blocks 6 are slidably installed on the inner walls of the two limiting grooves 502, and tooth grooves 601 are respectively opened at the bottom and top of the two rectangular blocks 6. Limiting protrusions 602 are fixedly installed on the sides of the two rectangular blocks 6 away from each other, and the two tooth grooves 601 are respectively engaged with the adjacent tooth column 2 401 and tooth column 1 302, and the two limiting protrusions 602 are respectively adapted to the adjacent limiting grooves 502.

[0030] The meshing of the tooth groove 601 with the tooth column 2 401 ensures the stable sliding of the rectangular block 6 in the limiting groove 502, and the rotation of the tooth column 2 401 can drive the rectangular block 6 to move in the horizontal direction. This design not only improves the transmission efficiency of the device, but also makes the operation easier. At the same time, the matching design of the limiting protrusion 602 and the limiting groove 502 further enhances the stability of the rectangular block 6 during the sliding process. The limiting protrusion 602 can effectively prevent the rectangular block 6 from deflecting or shaking during the sliding process, thereby ensuring the stability and reliability of the entire device.

[0031] like Figures 4 to 6 As shown, sliding grooves 501 are respectively opened on the outer walls of the two mounting blocks 5, and the two sliding grooves 501 respectively penetrate the corresponding mounting blocks 5, and the two ends of the rotating rod 1 3 respectively penetrate the adjacent sliding grooves 501 and are slidably connected with the adjacent sliding grooves 501.

[0032] By setting the sliding groove 501, there is a certain gap between the rotating rod 3 and the sliding groove 501. This design can effectively reduce friction and wear and extend the service life of the device.

[0033] like Figures 7 to 9 As shown, two limiting slide bars 8 are fixedly mounted on the inner walls of both sides of the detection device 1 , respectively. The four limiting slide bars 8 respectively penetrate the adjacent clamping blocks 7 and are slidably connected with the adjacent clamping blocks 7 .

[0034] The guiding effect of the limiting slide rod 8 prevents the clamping block 7 from deflecting or getting stuck during the sliding process, thereby ensuring the stability and reliability of the connection.

[0035] like Figure 1 to Figure 2 As shown, a wire receiving groove 103 is provided on the top of the detection device 1 , and two ends of the steel wire 403 pass through the two wire receiving grooves 103 respectively.

[0036] The steel wire 403 is used as a key component to connect the UAV and the detection device. The two ends of the steel wire 403 are cleverly passed through two wire collection grooves 103, which not only keeps the steel wire 403 neat and orderly during deployment and recovery, but also avoids operational inconvenience or safety hazards caused by messy cables, thereby ensuring the stability and reliability of the connection between the UAV and the detection device. like Figure 1 to Figure 2 As shown, two clamping sliding grooves 102 are provided on the top of the detection device 1 , and the tops of the two clamping blocks 7 respectively penetrate through the adjacent clamping sliding grooves 102 and are slidably connected with the adjacent clamping sliding grooves 102 .

[0037] The sliding connection between the clamping block 7 and the clamping sliding groove 102 enhances the connection stability between the clamping block 7 and the detection device 1, thereby ensuring the safe and smooth progress of the detection task.

[0038] like Figure 1 to Figure 2 As shown, a placement slot 104 is provided in the middle of the two wire collection slots 103 at the top of the detection device 1 , and two limit blocks 105 are fixedly installed on the top of the detection device 1 , and the two limit blocks 105 are respectively located on both sides of the rotating rod 2 4 .

[0039] Through the two limit blocks 105, the hook 901 can pass through the two limit blocks 105 and smoothly enter the placement groove 104, so that the subsequent two clamping blocks 7 can change to stably clamp and fix the hook 901, through the initial positioning of the placement groove 104, and then the firm clamping of the clamping block 7 - greatly enhancing the connection stability between the drone and the detection device, even under harsh external environmental conditions, it can effectively prevent falling off or loosening, ensuring the safety and smooth progress of the detection task.

[0040] The working principle and use process of the present invention: First, start the motor 2. The output shaft of the motor 2 rotates to drive the bevel gear 201 to rotate. The bevel gear 201 meshes with the bevel gear 2 301, thereby driving the bevel gear 2 301 to rotate. The bevel gear 2 301 drives the rotating rod 1 3 to rotate. The rotating rod 1 3 drives the two tooth columns 1 302 to rotate. The two tooth columns 1 302 mesh with the adjacent tooth grooves 601, thereby driving the two rectangular blocks 6 to move. The tooth grooves 601 also mesh with the tooth column 2 401, thereby driving the two tooth columns 2 401 and the rotating rod 2 4 to rotate. The rotation of the two rotating rods 2 4 drives the two winding rods 402 to rotate, and the steel wire 403 is loosened. The rotation of the rotating rod 1 3 causes the two clamping blocks 7 threadedly connected to the thread 303 to move along the axis of the rotating rod 1 3. The steel wire 403 moves horizontally. Due to the rigidity of the steel wire 403, the steel wire 403 is raised. Then the UAV 9 approaches the detection device 1. The raised steel wire 403 hooks the hook 901. After the hook 901 is connected to the steel wire 403, the motor 2 is started to rotate in the opposite direction, so that the steel wire 403 is slowly tightened and no longer raised. During the tightening process, the two clamping blocks 7 approach each other, and finally the hook 901 is located in the middle of the two arc-shaped clamping semi-circles 702. The bottom of the hook 901 also slides smoothly into the placement groove 104. The hook 901 is initially fixed by the contracted steel wire 403, and the hook 901 is fixed again by the two arc-shaped clamping semi-circles 702 to prevent the UAV 9 and the detection device 1 from falling off.
