Description

Technical Field

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

[0002] Insulators are important insulators that connect high-voltage transmission line towers and transmission lines. In addition to having good insulation performance, they must also have strong mechanical properties. Insulators are exposed to the strong electromagnetic environment brought by high-voltage transmission lines for a long time. Coupled with the adverse effects of the harsh outdoor environment, the insulation performance of insulators is easily deteriorated, resulting in poor insulators. Poor insulators will seriously affect the normal operation life of the transmission line. In particular, tension insulators are more likely to produce poor insulators due to the large mechanical stress. Therefore, preventive detection of tension insulators is an important guarantee for the safe operation of high-voltage transmission lines. At present, there are very mature detection devices for the insulation performance detection of insulators. However, due to the high installation height of the insulators and the certain danger of the high-voltage environment in which they are located, even if an automatic detection robot is used, it is still necessary to manually climb the tower to place them.

[0003] After searching, the Chinese invention patent application number is: 201710210097.2. The invention discloses a transmission line zero-value insulator live detection device and method based on a drone, including a drone, a measurement and control system, a connecting boom, a main movable flex arm, an upper mechanical claw movable flex arm, an upper mechanical claw, a lower mechanical claw movable flex arm, a lower mechanical claw, an upper voltage measurement probe and a lower voltage measurement probe. The upper mechanical claw and the lower mechanical claw are controlled to firmly grasp the upper and lower steel caps of the insulator respectively; the voltage signals of the upper and lower steel caps of the insulator are measured by the upper voltage measurement probe and the lower voltage measurement probe installed at the roots of the upper and lower mechanical claws, and the voltage signals are transmitted to the measurement and control system. The invention can realize the detection of zero-value insulators of transmission lines based on drones, greatly reducing the workload of line operation and maintenance personnel, improving the detection efficiency of zero-value insulators of transmission lines, and reducing the safety risks of tower climbing detection. However, the above patent has the following shortcomings: In the above patent, the drone is always in a flying state during the detection process, resulting in a limited number of insulators detected by the drone in one take-off and landing.

[0004] A Chinese patent with the application number of 201711131993.6 was retrieved. It is an insulator zero value detection drone, including a drone, a telescopic electric push rod fixedly connected to the bottom of the drone, the lower end of the telescopic electric push rod fixedly connected to a support frame, the support frame is fixedly connected to a tension insulator detection machine, and a position sensor is symmetrically arranged on the rotor support rod of the drone. The position sensor is provided with a vertical folding probe. A drone controller is arranged on the top of the drone, and the drone controller communicates wirelessly with the detection machine controller and the ground remote control. The present invention replaces personnel to climb the tower to measure the zero value of the insulator, thereby ensuring the safety of personnel. After the drone detects the position of the insulator, it automatically aligns and falls on the insulator string. The tension insulator detection machine can automatically walk along the double string of insulators, and can adapt to the change of the distance between the double string of insulators, and can conduct autonomous quantitative detection of the resistance value of each string of insulators, automatically alarm for zero value and low value insulators, and can store the detected resistance value. However, the device can only detect parallel insulator strings, and cannot detect V-shaped insulator strings, which greatly reduces the detection efficiency and detection quality of the insulator strings.

The arrangement of the crawler 9 is convenient for driving the device to move along the insulator string, and the movement of the device drives the detection mechanism 5 to move, thereby improving the detection efficiency and detection quality of the insulator string of the device, and the fixed frame 1 is used to ensure the normal operation of the device, the arrangement of the positioning mechanism 4 can achieve the purpose of positioning the detection mechanism 5, and the arrangement of the adjustment mechanism 3 can adjust the mounting frame 8, thereby achieving the purpose of adjusting the crawler 9, and the angle adjustment of the crawler 9 ensures that the crawler 9 can walk on the insulator strings in different installation methods, which greatly ensures the normal operation of the device.

[0052] In order to ensure that the device can detect insulator strings with different settings, such as Figure 3 , Figure 4As shown, the adjustment mechanism 3 includes a sliding frame 304, a motor 303, a threaded rod 305, a rotating arm 309, a bidirectional electric push rod 301, and a moving block 302.

[0069] As an optimization solution of this embodiment, in order to ensure that the fixing rod 501 moves smoothly in the process of forward and backward movement, and to prevent the detection probe 504 from shaking and causing damage to the detection probe 504 in the process of movement, as shown in FIG. Figure 8 As shown, the detection mechanism 5 further includes a first spring 507 , which is sleeved on the sliding rod 506 , and the first spring 507 is located between the fixing rod 501 and the supporting plate 801 .

[0070] The provision of the first spring 507 can ensure that when the second cylinder 503 moves the fixing rod 501 , the fixing rod 501 moves more smoothly, thereby greatly improving the detection efficiency and detection quality of the detection probe 504 on the insulator string.

[0071] As an optimization solution of this embodiment, in order to prevent the rotating arm 309 from driving the supporting plate 801 to move in the opposite direction and ensure the normal operation of the adjusting mechanism 3, as shown in FIG. Figure 7As shown, it also includes a pushing mechanism 2, which includes a pushing plate 201, a sliding rod 203, a blocking block 204 and a second spring 202. The sliding rod 203 is fixedly installed on one side of the sliding plate 306, and the blocking block 204 is fixedly installed on one end of the sliding rod 203. The pushing plate 201 is slidably installed on the sliding rod 203, and the second spring 202 is sleeved on the sliding rod 203, and the second spring 202 is located between the pushing plate 201 and the sliding plate 306.

[0072] The mutual cooperation between the push plate 201 and the second spring 202 can push one end of the support plate 801, ensuring that the adjustment mechanism 3 can adjust the support plate 801. The support plate 801 is adjusted to achieve the purpose of adjusting the angle of the track 9, ensuring that the track 9 can move on insulator strings arranged in different ways, thereby greatly improving the working efficiency of the device.
