Description

Technical Field

[0001] This utility model belongs to the field of circuit testing technology, specifically relating to a multi-unit tension insulator testing device mounted on a drone. Background Technology

[0002] Insulators play a crucial role in overhead transmission lines. Their main functions are twofold: firstly, to support and secure the overhead line; and secondly, to insulate conductors from each other and from grounding components. Therefore, insulators require excellent mechanical and electrical properties. High-quality insulators reduce energy loss, prevent short circuits and grounding faults, improve transmission efficiency, and ensure grid reliability. However, with prolonged loads and exposure to high-altitude environments, insulators are affected by environmental factors such as sunlight, wind, rain, and snow erosion, leading to resistance degradation and seriously threatening the safe operation of transmission lines.

[0003] Utility model patent 202420487884.7 relates to a probe device for insulator inspection using a drone-mounted lifting system. The robot frame is mounted on an insulator string by adjusting the extension of the telescopic rod, the center distance between two probes, and the probe length. The probe head is positioned between two insulator strings. The probe head can be driven by a servo motor to swing inwards towards one insulator string, placing the probe on the insulator cap to complete the inspection of that string. The probe head can then be driven by the servo motor to swing inwards towards the other string, placing the probe on the insulator cap to complete the inspection of both strings. However, because it only has one layer of inspection equipment, it cannot inspect the lower string of insulator strings arranged vertically, and it also suffers from low efficiency when inspecting multiple parallel insulator strings. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-unit tension insulator testing device mounted on a UAV, which has the advantage of being easy to test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-unit tension insulator testing device based on a drone, comprising a walking mechanism and a remote controller. A hanging ring is fixedly connected to the top outer wall of the walking mechanism, and a frame is fixedly connected to the outer wall of the walking mechanism. Two adjustable guide mechanisms are fixedly connected to the outer wall of the frame, and the guide mechanisms are symmetrical about the frame. A mounting bracket is fixedly connected to the outer wall of the frame, and the mounting bracket is located at the bottom of the guide mechanisms and is symmetrical about the frame. The device is characterized in that: the outer wall of the frame is fixedly connected to vertically distributed testing mechanisms, and the frame is a U-shaped structure extending downwards on both sides, with the frame opening facing downwards.

[0006] The above technical solution can effectively detect insulator strings distributed vertically. In use, the drone and the lifting ring are connected by multiple connecting rods, and then the drone is airlifted to the insulators of the transmission line. The walking mechanism can move on the insulators. There are two layers of detection mechanisms on the frame, which can detect the upper and lower insulator strings. The guide mechanism can adjust the spacing to accommodate insulator strings of different diameters. The guide mechanism also makes the equipment more stable when moving.

[0007] Preferably, the detection mechanism is a double-layer structure distributed on both sides, and the detection mechanism is mounted on two mounting brackets and two guide mechanisms.

[0008] The above technical solution can effectively detect insulator strings. Based on the distribution of insulator strings on the transmission line, detection mechanisms can be arranged on both sides of the frame, so that three parallel insulator strings can be detected simultaneously.

[0009] The detection mechanism is a double-layer structure distributed on one side, and the detection mechanism is installed on the mounting bracket and the guide mechanism on either side of the frame.

[0010] The above technical solution can effectively detect insulator strings. Based on the distribution of insulator strings on the transmission line, the detection mechanism can be arranged only on one side of the frame, so that two parallel insulator strings can be detected at the same time.

[0011] Preferably, the guiding mechanism includes a hollow connecting frame, with connecting blocks fixedly connected to the outer walls on both sides of the connecting frame, and an inclined sleeve fixedly connected to the bottom of the connecting block.

[0012] The above technical solution can serve as a guide mechanism for installation. The connecting blocks on both sides of the connecting frame can fix the connecting frame to the frame, and the bottom of the connecting blocks can be fitted with sleeves.

[0013] Preferably, a knob is rotatably connected to the upper oblique part of the sleeve, and the knob passes through the inside of the sleeve and is rotatably connected to a telescopic rod via a screw. A guide rod is fixedly connected between the outer walls of the two telescopic rods.

[0014] The above technical solution can achieve the effect of adjusting the spacing. By rotating the knob, the telescopic rod can be extended or retracted, thus controlling the spacing of the guide rods to adapt to the diameter of the insulator string. By using two guide rods to limit the movement on both sides of the insulator string, the equipment can move more smoothly on the insulator string.

[0015] Preferably, the detection mechanism includes a servo motor for driving, the output end of which is fixedly connected to a rotating frame, and probes are fixedly connected to the outer walls on both sides of the rotating frame.

[0016] The above technical solution can achieve the effect of contact detection. The servo motor can control the probe to make contact with both sides of the insulator sheet. In this way, the current can be used to determine whether the insulator sheet has failed, thus achieving the detection effect.

[0017] Preferably, the walking mechanism includes two side plates, with multiple gears rotatably connected between the two side plates. The outer walls of the gears are covered with tracks, and a motor is fixedly connected to the outer wall of one of the side plates, with the output end of the motor fixedly connected to one of the gears.

[0018] The above technical solution achieves the effect of movement. A motor can control the rotation of a gear. Since the track wraps around the gear, the track can be moved by controlling the movement of the track. Because the track is wide, the walking mechanism moves more smoothly and with less bumps.

[0019] Preferably, the frame includes two downward-opening U-shaped frames, with connecting parts fixedly connected to the outer walls on both sides of the U-shaped frames, and a side frame fixedly connected to the bottom outer wall of each connecting part.

[0020] The above technical solution can increase the length. The side frame can extend the length of both sides of the U-shaped frame, allowing the detection mechanism to detect the bottom insulator string. At the same time, the U-shaped frame can better wrap the top of the insulator string.

[0021] Preferably, an image module and a control module are fixedly connected to the bottom of the side frame, and the image module and control module bridge the two U-shaped frames. The image module and control module have a counterweight function.

[0022] The above technical solution can serve the functions of communication and monitoring. The image module can process the images captured by the camera, and the control module can receive control commands from the remote control to control the movement of the equipment. At the same time, the image module and the control module will install counterweights according to their own weight to ensure the balance of the two sides of the equipment.

[0023] Preferably, the mounting bracket includes a horizontally placed connecting frame, with mounting blocks fixedly connected to the outer walls on both sides of the connecting frame, and an opening for mounting the testing mechanism is provided on the middle outer wall of the connecting frame.

[0024] The above technical solution can serve as a connection, and the testing mechanism can be installed through the connecting frame. The connecting frame can be installed with the side frame through the mounting blocks on both sides.

[0025] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the drone and the lifting ring are connected by a multi-section connecting rod, and then it is airlifted to the insulator of the power transmission line. It can move on the insulator through the walking mechanism. There are two layers of detection mechanisms on the frame, so that the upper and lower insulator strings can be detected. The guide mechanism can adjust the spacing, so it can adapt to insulator strings of different diameters. The guide mechanism can make the equipment more stable when moving.

[0026] 2. Based on the distribution of insulator strings on the transmission line, detection mechanisms can be arranged on both sides of the frame, so that three parallel insulator strings can be detected simultaneously. Alternatively, based on the distribution of insulator strings on the transmission line, detection mechanisms can be arranged on only one side of the frame, so that two parallel insulator strings can be detected simultaneously.

[0027] 3. The connecting blocks on both sides of the connecting frame can fix the connecting frame to the frame. At the same time, the bottom of the connecting block can be installed with a sleeve. By rotating the knob, the telescopic rod can be extended or retracted, thus controlling the spacing of the guide rods to adapt to the diameter of the insulator string. By limiting the two guide rods on both sides of the insulator string, the equipment can move more smoothly on the insulator string. Attached Figure Description

[0030] 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.

[0031] Example 1: Please see Figures 1-5 This utility model provides a technical solution: a multi-unit tension insulator testing device based on a drone, including a walking mechanism 1 and a remote controller 9. A hanging ring 2 is fixedly connected to the top outer wall of the walking mechanism 1, and a frame 3 is fixedly connected to the outer wall of the walking mechanism 1. Two adjustable guide mechanisms 5 are fixedly connected to the outer wall of the frame 3, and the guide mechanisms 5 are symmetrical about the frame 3. A mounting bracket 6 is fixedly connected to the outer wall of the frame 3, and the mounting bracket 6 is located at the bottom of the guide mechanisms 5 and is symmetrical about the frame 3. The feature is that the outer wall of the frame 3 is fixedly connected to a detection mechanism 4 distributed vertically, and the frame 3 is a U-shaped structure extending downward on both sides, with the opening of the frame 3 facing downward.

[0032] In this implementation scheme, during use, the drone and the lifting ring 2 are connected by a multi-section connecting rod, and then the drone is airlifted to the insulator of the power transmission line. The walking mechanism 1 can move on the insulator. There are two layers of detection mechanisms 4 on the frame 3, which can detect the upper and lower insulator strings. The guide mechanism 5 can adjust the spacing to accommodate insulator strings of different diameters. The guide mechanism 5 can make the equipment more stable when moving.

[0033] Example 2: Please see Figure 1 The present invention provides a technical solution: the detection mechanism 4 is a double-layer structure distributed on both sides, and the detection mechanism 4 is installed on two mounting brackets 6 and two guide mechanisms 5.

[0034] In this implementation scheme, based on the distribution of insulator strings on the transmission line, detection mechanisms 4 can be arranged on both sides of the frame 3, so that three parallel insulator strings can be detected simultaneously.

[0035] Example 3: Please see Figure 1 The present invention provides a technical solution: the detection mechanism 4 is a double-layer structure distributed on one side, and the detection mechanism 4 is installed on the mounting bracket 6 and the guide mechanism 5 on either side of the frame 3.

[0036] In this implementation scheme, based on the distribution of insulator strings on the transmission line, the detection mechanism 4 can be arranged only on one side of the frame 3, so that two parallel insulator strings can be detected at the same time.

[0037] Example 4: Please see Figure 4 Based on Embodiment 1, this utility model provides a technical solution: the guide mechanism 5 includes a hollow connecting frame 500, connecting blocks 501 are fixedly connected to the outer walls of both sides of the connecting frame 500, an inclined sleeve 502 is fixedly connected to the bottom of the connecting block 501, a knob 503 is rotatably connected to the upper oblique part of the sleeve 502, the knob 503 passes through the inside of the sleeve 502 and is rotatably connected to a telescopic rod 504 through a screw, and a guide rod 505 is fixedly connected between the outer walls of the two telescopic rods 504.

[0038] In this embodiment, the connecting blocks 501 on both sides of the connecting frame 500 can fix the connecting frame 500 to the frame 3. At the same time, the sleeve 502 can be installed at the bottom of the connecting block 501. By rotating the knob 503, the telescopic rod 504 can be extended or retracted, thus controlling the spacing of the guide rods 505 to adapt to the diameter of the insulator string. By limiting the two guide rods 505 on both sides of the insulator string, the equipment can move more smoothly on the insulator string.

[0039] Example 5: Please see Figures 2-4 Based on Embodiment 1 and Embodiment 2, this utility model provides a technical solution: the detection mechanism 4 includes a servo motor 400 for driving, the output end of the servo motor 400 is fixedly connected to a rotating frame 401, and probes 402 are fixedly connected to the outer walls on both sides of the rotating frame 401. The walking mechanism 1 includes two side plates 100, and multiple synchronous pulleys 102 are rotatably connected between the two side plates 100. The outer wall of the gear 102 is covered with a track 103. A motor 101 is fixedly connected to the outer wall of one side plate 100, and the output end of the motor 101 is fixedly connected to a gear 102.

[0040] In this embodiment, the servo motor 400 can control the probe 402 to contact both sides of the insulator sheet, so that the current can be used to determine whether the insulator sheet is faulty, thereby achieving the detection effect. The motor 101 can control a gear 102 to rotate. Since the track 103 wraps around the gear 102, the track 103 can be moved by the gear 102. Because the track 103 is wide, the walking mechanism 1 will move more smoothly and with less bumps.

[0041] Example 6: Please see Figures 3-5Based on Embodiments 1, 2, and 3, this utility model provides a technical solution: Frame 3 includes two downward-opening U-shaped frames 300. Connecting parts 301 are fixedly connected to the outer walls on both sides of the U-shaped frames 300. Side frames 302 are fixedly connected to the bottom outer wall of each connecting part 301. Image module 7 and control module 8 are fixedly connected to the bottom of the side frames 302. Image module 7 and control module 8 bridge the two U-shaped frames 300. Image module 7 and control module 8 have a counterweight function. Mounting bracket 6 includes a horizontally placed connecting frame 600. Mounting blocks 601 are fixedly connected to the outer walls on both sides of the connecting frame 600. An opening for mounting the detection mechanism 4 is provided in the middle outer wall of the connecting frame 600.

[0042] In this embodiment, the side frame 302 can extend the length of both sides of the U-shaped frame 300, allowing the detection mechanism 4 to detect the bottom insulator string. At the same time, the U-shaped frame 300 can better wrap the top of the insulator string. The image module 7 can process the image captured by the camera, and the control module 8 can receive control commands from the remote controller 9 to control the movement of the equipment. Simultaneously, the image module 7 and the control module 8 will install counterweights according to their own weight to ensure the balance of both sides of the equipment. The detection mechanism 4 can be installed through the connecting frame 600, which can be installed with the side frame 302 through the mounting blocks 601 on both sides.

[0043] The working principle and usage process of this utility model are as follows: In use, the drone and lifting ring 2 are connected via multi-section connecting rods, and then it is airlifted to the insulators of the transmission line. The walking mechanism 1 allows it to move on the insulators. There are two layers of detection mechanisms 4 on the frame 3, allowing for the detection of the upper and lower insulator strings. The guide mechanism 5 can adjust the spacing to accommodate insulator strings of different diameters. The guide mechanism 5 also ensures greater stability during movement. Depending on the distribution of insulator strings on the transmission line, detection mechanisms 4 can be arranged on both sides of the frame 3. Simultaneously, three parallel insulator strings are tested. Based on the distribution of insulator strings on the transmission line, the testing mechanism 4 can be arranged on only one side of the frame 3, allowing simultaneous testing of two parallel insulator strings. Connecting blocks 501 on both sides of the connecting frame 500 can fix the connecting frame 500 to the frame 3. A sleeve 502 can be installed at the bottom of the connecting block 501. Rotating the knob 503 controls the extension and retraction of the telescopic rod 504, thus controlling the spacing of the guide rods 505 to accommodate the diameter of the insulator strings. The two guide rods 505 are used to inspect the insulator strings on both sides. Limit switches allow for smoother movement of the insulator string. A servo motor 400 controls probes 402 to contact both sides of the insulator discs, allowing current flow to determine if the insulator discs are faulty, thus achieving a detection effect. A motor 101 controls the rotation of a gear 102. Since the track 103 encloses the gear 102, the gear 102 controls the movement of the track 103. Because the track 103 is wide, the walking mechanism 1 moves more smoothly with less bumping. The side frame 302 extends the U-shaped frame 300. The length of both sides allows the detection mechanism 4 to detect the bottom insulator string, while the U-shaped frame 300 can better wrap the top of the insulator string. The image module 7 can process the image captured by the camera, and the control module 8 can receive control commands from the remote control 9 to control the movement of the equipment. At the same time, the image module 7 and the control module 8 will install counterweights according to their own weight to ensure the balance of both sides of the equipment. The detection mechanism 4 can be installed through the connecting frame 600, which can be installed with the side frame 302 through the mounting blocks 601 on both sides.
