Description

Technical Field

[0001] This utility model belongs to the field of high-voltage transmission line testing technology, specifically a rotor-type tension insulator deterioration detection device. Background Technology

[0002] Insulator strings are very common in overhead transmission lines. They must bear the tension of the transmission line and provide electrical insulation between the line and the tower. Therefore, they play a crucial role in overhead transmission lines. For these reasons, insulators need to have good mechanical and electrical properties. However, in real-world operating environments, insulators are exposed to high-altitude loads for extended periods, subject to various environmental factors, leading to structural or resistance degradation, which seriously threatens the safety of the transmission line.

[0003] To ensure the safety of power transmission lines and the smooth operation of power transmission, insulator strings need to be inspected, maintained, and replaced regularly. Common methods in the insulator inspection industry include: traditional manual tower climbing inspection, inspection using drone-based combined inspection devices, and inspection using drones with mounted inspection loads.

[0004] Currently, the most widely used method in the insulator inspection industry is to use drones to mount inspection payloads. The principles behind this method are varied, but some common methods include: combining AI algorithms and IoT technology to analyze data from on-site images of the insulators to determine their health status; using infrared cameras to observe for abnormal heating; using ultraviolet cameras to observe for partial discharge phenomena to analyze the insulator's health; and using sensors to detect the electric field near the insulator to determine its health. Application No. 201821177218.4 discloses a tension insulator testing device, which includes: a drone, a first camera, a processor, a flight control system, sensors, and a testing mechanism. The drone includes: a drone body, an arm, a propeller, and landing gear; one end of the arm is connected to the drone body, and the other end is connected to the propeller; the landing gear is located at the bottom of the drone body; the first camera is located on the outside of the drone body; the processor is used to receive the images captured by the first camera; the flight control system is used to receive the processing results of the processor and to control the drone by controlling the propeller; the sensors are located on the drone body; and the testing mechanism is connected to the drone body.

[0005] However, the following problems were found in the implementation of the relevant technology: the existing device needs to be lowered onto the insulator string during operation, but the surface of the insulator string can be approximated as a cylindrical surface, which is not suitable for the device to be lowered, and the device is at risk of falling.

[0006] To address the problems mentioned in the background art, this utility model provides a rotary-type tension insulator deterioration detection device, which can move on insulator strings of different diameters and has the advantages of being able to stably detect the deterioration of insulator strings and being less prone to falling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotor-type tension insulator deterioration detection device, comprising an arched frame and a control system, a walking mechanism, a detection mechanism and a guiding mechanism installed on the surface of the arched frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a rotor-type tension insulator deterioration detection device, including an arched frame 1 and a control system, a walking mechanism, a detection mechanism and a guiding mechanism installed on the surface of the arched frame 1. Two sets of rotors 16 with opposite rotation directions are rotatably installed at the four corners of the arched frame 1. The device can be driven to fly by the two sets of rotors 16 using existing principles. A binocular camera 17 is installed in the center of each of the four sides of the arched frame 1. The binocular camera 17 is used to adjust the flight attitude and measure the distance during flight to achieve autonomous landing function. The testing mechanism includes a servo motor 2 installed at the bottom center of an arched frame 1 and an adjusting frame 3 connected to the output end of the servo motor 2. Both the front and rear ends of the adjusting frame 3 are connected to sleeves 4, and elastic probes 5 are fixedly inserted into the inner side of the sleeves 4. During operation, the servo motor 2 rotates, causing the probes 5 to swing and contact the steel caps at both ends of the insulator sheet, thus directly contacting the insulator to test its resistance. The elasticity of the probes 5 ensures good contact during the contact process, increases the service life of the probes 5, and reduces the operational difficulty of the testing work. The walking mechanism includes two mounting brackets 6 symmetrically installed at the bottom of the arched frame 1 and a drive motor 7 installed on the side of the mounting bracket 6 away from the probe 5. A stepping rod 8 is provided on the side of the mounting bracket 6 close to the probe 5. The top of the stepping rod 8 has two small arms 9 symmetrically integrally formed, and the two small arms 9 are movably connected to the two ends of the mounting bracket 6. The output end of the drive motor 7 is connected to one of the small arms 9. A toothed rubber strip 10 is connected to the bottom of the stepping rod 8. The drive motor 7 is installed on the other side to drive the small arm 9 to rotate, thereby driving the stepping rod 8 to move, thus realizing the reciprocating stepping motion of the entire device. The guiding mechanism includes four connecting frames 11 symmetrically installed on both sides of the bottom of the arched frame 1, with the two outer connecting frames 11 located within the inner arc surface of the bottom of the arched frame 1. A guide rod 12 is provided at the bottom of the connecting frame 11, and two support rods 13 are integrally formed symmetrically at the top of the guide rod 12. The support rods 13 are movably inserted into the bottom of the connecting frame 11, and a spring (not shown in the figure) is connected between the top of the support rod 13 and the inner top of the connecting frame 11. During the process of the device falling as a whole, the guide rod 12 first contacts the insulator. Due to its own weight, it will compress the spring to achieve the effect of adapting to insulators of different sizes. The control system includes control boxes 14 symmetrically mounted on the top of the arched frame 1. Inside the control boxes 14 are installed an algorithm module, a drive module, a detection module, an image recognition and transmission module, a data storage module, a network module, and a power supply module. The drive module is synchronously connected to two drive motors 7. The algorithm module primarily controls and corrects the attitude of the device during flight; combined with the image recognition module, it enables the device to autonomously land. The drive module synchronously drives the drive motors 7 of the two walking mechanisms, ensuring the device moves smoothly from side to side and preventing tipping. The detection module primarily uses probes 5... The resistance of the insulator is measured by attaching it to the steel caps at both ends of the insulator. The image recognition and transmission module has multiple functions: first, it observes obstacles and analyzes distances through the binocular cameras 17 around the insulator during flight; second, it observes and records the appearance of the insulator being tested and sends it to the control terminal during the detection process, while the device also transfers the obtained data to the data storage module; third, it works with the algorithm module to realize autonomous landing and autonomous inspection functions. The data storage module summarizes and organizes the obtained data and uploads it to the control terminal for easy retrieval by personnel. The network module is used to establish a connection with the control terminal.

[0023] Specifically, the bottom of the arched frame 1 is symmetrically equipped with two support legs 18 for landing and support, and the front and rear ends of the support legs 18 are fitted with rubber sleeves to prevent other structures at the bottom of the device from being worn during landing.

[0024] Furthermore, a main frame 15 is installed on the top of the arched frame 1, and front and rear binocular cameras 17 are respectively installed on the front and rear sides of the main frame 15. Left and right binocular cameras 17 are respectively installed on the corresponding sides of the left and right control boxes 14, ensuring that the four binocular cameras 17 can fully detect the surrounding environment.

[0025] Furthermore, the two inner connecting brackets 11 are symmetrically installed at the bottom of the main frame 15, and together with the two outer connecting brackets 11, they can be stably placed on top of the two insulator strings.

[0026] It is worth noting that the network module includes two wireless network cards, which are located in two separate control boxes 14. The arrangement of the two wireless network cards ensures that the device can establish a stable connection with the control terminal using the UDP protocol.

[0027] It is worth noting that the stepping rod 8 and the forearm 9, as well as the guide rod 12 and the support rod 13, are all die-cast integral structures. The die-cast integral structure has the advantages of high structural strength and not being easily damaged.

[0028] It is worth noting that the bottom of the arched frame 1 has a positioning groove, and the top of the connecting frame 11 is fixedly inserted into the corresponding positioning groove, which facilitates the positioning and installation of the connecting frame 11.

[0029] It is worth noting that the top of the control box 14 is on the same horizontal plane as the top of the arched frame 1, which avoids accidental wear on the top of the control box 14 and reduces the probability of it being accidentally bumped. The main frame 15 is flush with the front and rear sides of the arched frame 1, and the main frame 15 can provide protection for the top of the device.

[0030] It is worth noting that the servo motor 2 is mounted on top of a mounting base, which is located at the bottom center of the arched frame 1. The servo motor 2 can be removed by removing the mounting base.

[0031] It is worth noting that the bottom of the support leg 18 is 3-5 cm lower than the bottom of the probe 5, so that the support leg 18 can make contact with the ground first when the device is lowered.

[0032] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0033] Working Principle: First, place the device in a suitable open area for takeoff. Operate the device to take off and slowly approach the target insulator string. Adjust the flight attitude and land. During landing, the guide rod 12 of the device will first contact the insulator. Due to its own weight, the spring inside the connecting frame 11 will be compressed, thus positioning the guide rods 12 on both sides in a position suitable for the current insulator. After the device lands on the target insulator string, it begins to move. During this movement, the drive module synchronously drives the drive motors 7 on both sides to rotate the corresponding small arms 9, thereby rotating the two stepping rods 8 as a whole. After the stepping rods 8 contact the upper edge of the insulator string, the entire device is lifted by the torsional reaction force, causing the entire device to move forward. The device moves to achieve the purpose of stepping, and performs detection while stepping. The servo motor 2 rotates to make the probe 5 attach to the steel cap of one side of the insulator, detect the resistance value of the insulator, record it and send it to the control terminal connected via wireless network card. The servo motor 2 is rotated in the opposite direction to make the probe 5 attach to the steel cap of the other side of the insulator, record it and send the resistance value of the insulator. At the same time, the four binocular cameras 17 on this device will record and send the appearance of the insulator being tested. After completing these steps, the device will move to the next insulator and repeat the above steps until the test is completed. After the test is completed, the control device returns to the landing position to wait for the next command. At this time, we can operate the device to take off and enter the next test operation or return to the ground to complete the operation.
