Description

Technical Field

[0001] The invention relates to the technical field of insulator detection, in particular to a portable binocular vision on-site detection device for damaged insulator areas. Background Art

[0002] Insulators are devices installed between conductors at different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress. Insulators come in many types and shapes, but they are all composed of two major parts: insulating parts and connecting fittings. Insulators not only provide stable mechanical support for conductors that transmit current, but more importantly, they can effectively prevent current from directly contacting the earth and avoid the occurrence of grounding accidents, playing an important role in overhead transmission lines.

[0003] Existing insulators are often damaged due to environmental and physical factors during use. If not discovered in time, it will cause damage to power transmission. However, current insulator detection technology has limitations. It can only be detected one by one and cannot be adjusted according to the size of the insulator, making it difficult for the detection equipment to clearly and stably detect the degree of damage on the insulator surface.

[0004] In the design of existing insulator contact resistance detection equipment, the detection rod is usually fixed, which means that they can only measure a single or multiple insulators one by one at a time, and cannot adapt to and measure the resistance values ​​of different insulators at the same time. This design limits the detection efficiency, especially in scenarios where a large number of insulators need to be detected quickly and accurately. In addition, when the detection equipment moves on the insulator, due to the presence of a certain gap between the insulators, this will cause the equipment to vibrate when passing through these gaps. This vibration is extremely unfavorable for the precision detection devices inside the equipment. In the long run, the vibration may cause the devices to loosen, wear or even be damaged, thereby affecting the accuracy and service life of the equipment. Therefore, how to reduce the vibration of the equipment during movement and protect the precision detection devices has become an important issue in the current design of insulator detection equipment.

[0005] Therefore, a portable binocular vision on-site detection device for insulator damage area is proposed to solve the above problems. Summary of the invention

[0009] The multifunctional resistance measuring mechanism is arranged in the insulator body, and the multifunctional resistance measuring mechanism is used for detection and adjustment of the detection frame.

[0010] Preferably, the spacing adjustment stabilization crawling mechanism includes a servo motor, which is installed in the detection frame. A first driving tooth is fixedly connected to the driving shaft of the servo motor, and a gear plate is meshed on the tooth surface of the first driving tooth. A support plate is rotatably connected to the middle part of the gear plate, and the upper surface of the support plate is fixedly connected to the detection frame.

[0011] Preferably, the gear plate is symmetrically rotatably connected to an eccentric push plate on both sides of the eccentric portion, and the eccentric push plate is rotatably connected to a support rod at one end away from the gear plate. Both ends of the support rod are fixedly connected to the driving device, and dampers are installed at both ends of the driving device.

[0012] Preferably, the damper is rotatably connected to the detection frame at one end away from the driving device, a buffer spring is sleeved on the outer surface of the damper, one end of the buffer spring is fixedly connected to the driving device, and the other end of the buffer spring is fixedly connected to the damper.

[0013] Preferably, the multifunctional resistance measuring mechanism comprises a rotating plate, the middle portion of which is rotatably connected to the bottom of the detection frame, a driving motor is installed at the bottom of the detection frame, and a driving shaft of the driving motor is fixedly connected to the middle portion of the rotating plate.

[0014] Preferably, both ends of the rotating plate are rotatably connected to pull plates, one end of the pull plate away from the rotating plate is rotatably connected to a fixed block, and one side of the fixed block away from the pull plate is fixedly connected to a clamping plate.

[0015] Preferably, a curved tooth screw block is symmetrically rotatably connected in the middle of the splint, the curved tooth screw blocks symmetrically arranged in the splint are meshed with each other, a magnetic telescopic rod is fixedly connected to the curved tooth screw block, and a guide limit shaft is slidably connected in the middle of the curved tooth screw block.

[0016] Preferably, both ends of the guide limit shaft are rotatably connected to the inner wall of the detection frame, the guide limit shaft is symmetrically rotatably connected in the clamping plate, and a rotating tooth is fixedly connected to one side of the guide limit shaft close to the inner wall of the detection frame, and the tooth surface of the rotating tooth is meshed with a second driving tooth.

[0017] Preferably, the balancing telescopic support rod is symmetrically arranged on the detection frame, balancing frames are arranged on both sides of the detection frame, and a camera device is installed at the bottom of the balancing frame, and the upper end of the balancing frame is fixedly connected to the balancing telescopic support rod.

[0018] Compared with the prior art, the present invention provides a portable binocular visual insulator damage area on-site detection device, which has the following beneficial effects:

[0019] 1. The existing insulator damage area detection technology usually uses an aircraft to carry the detection equipment to the insulator row to be detected, and starts to take photos of individual insulators after the equipment is started. The detection efficiency and accuracy are low and the environmental adaptability is poor. This solution adds a leg that can be extended on the basis of the existing equipment, so that the equipment can be carried in the middle of two rows of insulators and detect two rows of insulators at the same time, which improves the detection efficiency. At the same time, this solution adds a rubber pulley that can be adjusted in angle. By adjusting the angle of the leg at the bottom of the equipment, it can quickly adapt to the detection of insulators of different sizes;

[0020] Furthermore, by installing an adjustable bracket on the equipment of this solution, the cameras installed at the bottom of the balance brackets on both sides can be used to synchronously take pictures of the inside and outside of the insulator at different angles. Compared with the monocular detection technology, this solution "uses two cameras (binocular vision) to complete the shooting of one or more insulators at different angles, and uses the detection algorithm to realize the detection of the damaged area of ​​the insulator". It not only enhances the detection flexibility but also reduces the equipment detection time and increases the efficiency of the detection of the damaged area of ​​the insulator.

[0021] At the same time, the buffer spring setting can reduce the vibration generated when the device moves on the insulator, and reduce the damage to the high-precision sensors inside the device caused by vibration.

[0022] 2. The rotation of the gear plate driven by the first driving tooth can drive the eccentric push plate at the eccentric position to start rotating around the center point of the gear plate. The rotation of the gear plate can change the lateral force of the eccentric push plate, thereby changing the lateral position of the eccentric push plate. The eccentric push plate can directly drive the support rod to drive the swing angle of the driving device on the detection frame. Through the angle adjustment of the driving device, different insulator spacings can be quickly matched, avoiding the field of view obstruction or focal misalignment caused by the mismatch of the spacing of the traditional fixed bracket, ensuring that the binocular vision system is always in the best stereo matching baseline.

[0023] 3. In this solution, the driving device is symmetrically arranged on both sides of the detection frame, and the damper is symmetrically installed at both ends of the driving device. The elastic deformation of the buffer spring installed on the driving device can absorb the impact energy when moving on the insulation. The damper converts the vibration energy into heat energy dissipation through the fluid resistance of the hydraulic oil inside it, which significantly reduces the damage of high-frequency vibration during equipment operation to internal precision components, such as sensors and cameras.

[0037] 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.

[0038] The present invention is further described in detail below based on the accompanying drawings and embodiments;

[0039] First embodiment

[0040] Please refer to Figures 1 to 9 As shown:

[0041] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a portable binocular vision insulator damaged area on-site detection device, including an insulator body 1, the insulator body 1 is symmetrically arranged, a detection frame 11 is arranged above the insulator body 1, a battery module 13 is installed on the upper surface of the detection frame 11, and a balanced telescopic support rod 12 is installed on both sides of the battery module 13. A driving device 14 is arranged on both sides of the detection frame 11, characterized in that it also includes a spacing adjustment stable crawling mechanism 2 and a multifunctional resistance measuring mechanism 3;

[0042] The spacing adjustment stable crawling mechanism 2 is arranged on both sides of the detection frame 11, and the spacing adjustment stable crawling mechanism 2 is used for climbing adjustment when detecting different insulator bodies 1;

[0043] The multifunctional resistance measuring mechanism 3 is arranged in the insulator body 1, and the multifunctional resistance measuring mechanism 3 is used for detecting and adjusting the detection frame 11;

[0044] Among them, by balancing the telescopic support rod 12 and the battery module 13, the support plate 23 can be extended and folded, and the battery module 13 can be detachably installed, so that the device can be folded up when not in use, reducing the volume and being easy to carry and store; and when needed, it can be easily unfolded and restored to a working state.

[0045] Specifically, Figure 6As shown, the servo motor 21 is installed in the detection frame 11, and a first driving tooth 22 is fixedly connected to the driving shaft of the servo motor 21, and a gear plate 24 is meshed with the tooth surface of the first driving tooth 22, and a support plate 23 is rotatably connected to the middle of the gear plate 24, and the upper surface of the support plate 23 is fixedly connected to the detection frame 11; the eccentric part of the gear plate 24 is symmetrically rotatably connected to the eccentric push plate 25 on both sides, and the eccentric push plate 25 is rotatably connected to the end away from the gear plate 24 with a support rod 26, and both ends of the support rod 26 are fixedly connected to the driving device 14, and dampers 27 are installed at both ends of the driving device 14;

[0046] The first driving teeth 22 and the gear plate 24 are meshed with each other. The first driving teeth 22 drive the gear plate 24 to rotate, which can drive the eccentric push plate 25 at the eccentric position to start rotating around the center point of the gear plate 24. The rotation of the gear plate 24 can change the lateral force of the eccentric push plate 25, thereby changing the lateral position of the eccentric push plate 25. The eccentric push plate 25 can directly drive the support rod 26 to drive the swing angle of the driving device 14 on the detection frame 11. Through the angle adjustment of the driving device 14, different insulator spacings can be quickly matched, avoiding the problem of field of view obstruction or focal misalignment caused by the mismatch of spacing of the traditional fixed bracket, and ensuring that the binocular vision system is always in the best stereo matching baseline;

[0047] Furthermore, the balanced telescopic support rod 12 is symmetrically arranged on the detection frame 11, and a balanced frame is arranged on both sides of the detection frame 11, and a camera device is installed at the bottom of the balanced frame, and the upper end of the balanced frame is fixedly connected to the balanced telescopic support rod 12;

[0048] Among them, the transmission belt of the driving device 14 in contact with the insulator adopts an anti-slip rubber pad, which can keep the equipment stable in complex terrains such as the middle of two insulator rows and the crossarm of the tower, and reduce the impact of vibration on binocular image acquisition.

[0049] In this solution, balancing frames are set on both sides of the detection frame 11. The auxiliary setting of the balancing frames can increase the stability of the detection frame 11 during detection and movement. At the same time, this solution adopts an extendable balancing telescopic support rod 12. The extension of the balancing telescopic support rod 12 can effectively control the distance between the balancing frames on both sides of the detection frame 11 and the detection frame 11, so that it can be suitable for the upper insulator spacing between different electrical connections.

[0050] Further, if Figure 4 and Figure 5 As shown, one end of the damper 27 away from the driving device 14 is rotatably connected to the detection frame 11, and a buffer spring 28 is sleeved on the outer surface of the damper 27, one end of the buffer spring 28 is fixedly connected to the driving device 14, and the other end of the buffer spring 28 is fixedly connected to the damper 27;

[0051] Among them, the driving device 14 is symmetrically arranged on both sides of the detection frame 11, and the damper 27 is symmetrically installed at both ends of the driving device 14. The elastic deformation of the buffer spring 28 installed on the driving device 14 can absorb the impact energy when moving on the insulation, and the damper 27 converts the vibration energy into heat energy dissipation through the fluid resistance of the hydraulic oil inside it, which significantly reduces the damage of high-frequency vibration during equipment operation to internal precision components such as sensors and cameras.

[0052] Specifically, Figure 7 As shown, the middle part of the rotating plate 31 is rotatably connected to the bottom of the detection frame 11, a driving motor is installed at the bottom of the detection frame 11, and the driving shaft of the driving motor is fixedly connected to the middle part of the rotating plate 31; the two ends of the rotating plate 31 are rotatably connected to the pulling plate 32, the pulling plate 32 is rotatably connected to the end away from the rotating plate 31 with a fixed block 33, and the fixed block 33 is fixedly connected to the side away from the pulling plate 32 with a clamping plate 34;

[0053] Wherein, the clamping plate 34 is symmetrically arranged in the detection frame 11;

[0054] In this solution, the pull plate 32 at the bottom of the detection frame 11 can be controlled to move simultaneously by rotating the rotating plate 31, and the movement of the clamping plate 34 in the middle of the detection frame 11 can be controlled by pulling the pull plate 32;

[0055] Further, if Fig. 9 As shown, the middle part of the clamping plate 34 is symmetrically connected to the arc surface tooth screw block 35 for rotation, the arc surface tooth screw blocks 35 symmetrically arranged in the clamping plate 34 are meshed with each other, a magnetic telescopic rod 39 is fixedly connected to the arc surface tooth screw block 35, and a guide limit shaft 36 is slidably connected to the middle part of the arc surface tooth screw block 35; both ends of the guide limit shaft 36 are rotatably connected to the inner wall of the detection frame 11, the guide limit shaft 36 is symmetrically connected to the clamping plate 34, and a rotating tooth 37 is fixedly connected to the side of the guide limit shaft 36 close to the inner wall of the detection frame 11, and the tooth surface of the rotating tooth 37 is meshed with a second driving tooth 38;

[0056] Among them, the guide limit shaft 36 rotates symmetrically on the clamping plate 34, and the clamping plate 34 can also slide on the guide limit shaft 36. The rotation of the guide limit shaft 36 on one side can control the mutual rotation between the arc surface tooth screw blocks 35. Since the magnetic telescopic rod 39 is fixedly connected to the non-tooth surface of the arc surface tooth screw block 35, the swing between the magnetic telescopic rods 39 can be controlled by the mutual rotation of the arc surface tooth screw blocks 35.

[0057] This solution can not only control the magnetic telescopic rods 39 on both sides to swing synchronously to measure the resistance between the insulators, but also control the magnetic telescopic rods 39 through the synchronous design. Figure 3The magnetic telescopic rod 39 shown in the figure can synchronously detect the insulators on both sides. Compared with the prior art that can only measure one insulator in a string, which is inefficient, the present design can synchronously test any group of two insulator strings, which not only increases the convenience of measurement, but also can synchronously take pictures of the insulators on both sides through the balance frames on both sides of the detection frame 11, thereby increasing the efficiency of insulator detection;

[0058] Furthermore, through the setting of the clamping plate 34 in the present solution, the sliding distance of the clamping plate 34 on the guide limit shaft 36 can be controlled by a motor, and the sliding of the clamping plate 34 can synchronously control the arc-shaped tooth screw block 35 that slides symmetrically on the guide limit shaft 36 to change the measurement interval, so that the number of different insulator strings can be measured, which is not limited to the measurement of a single insulator, thereby increasing the applicability of the use of the present device.

[0059] Second embodiment

[0060] The steps for collecting insulator damage in this scheme are as follows:

[0061] Step 1, preliminary preparation: confirm that the battery power of the battery module 13 in the detector designed by our party is greater than 80%, the probe is not rusted or oxidized, and the surface of the magnetic telescopic rod 39 is dry and the support rod 26 is dry. At the same time, the ambient humidity is less than 85%, and the temperature is -20℃~50℃. If it exceeds the range, the temperature control compensation function needs to be enabled.

[0062] Step 2, parameter configuration: According to the insulator type, support / suspension type and diameter, adjust the distance between the double-sided synchronous detection probes, and control the start and stop of the equipment.

[0063] Step 3: Data collection: Place the device in the middle of two strings of insulators, adjust the driving device 14 to fit the insulators, so that the device can stably crawl on the insulators, and start the device to measure data.

[0064] The specific implementation steps of the above step three are as follows:

[0065] First, the operator operates the device through a large drone, and carries the device to the middle of the insulator rows on both sides by the drone. At this time, the spacing in the device is adjusted by controlling the stable crawling mechanism 2. At this time, Figure 1 As shown, the drive devices 14 on both sides of the detection frame 11 are adjusted so that the drive devices 14 and the insulator row form a stable support angle. Figure 6As shown, the synchronous rotation of the first driving tooth 22 is controlled by starting the servo motor 21, and the meshing gear plate 24 is driven to start reverse rotation by the rotation of the first driving tooth 22. The eccentric push plate 25 can be controlled to pull the support rod 26 under the rotation of the gear plate 24. The eccentric push plate 25 can directly drive the support rod 26 to drive the swing angle of the driving device 14 on the detection frame 11. The angle adjustment of the driving device 14 can quickly match different insulator spacings, avoid the problem of field of view obstruction or focal misalignment caused by the mismatch of spacing of the traditional fixed bracket, and ensure that the binocular vision system is always in the best stereo matching baseline;

[0066] When the device is continuously moving and collecting on the insulator, the transmission belt in contact with the insulator through the driving device 14 in this solution adopts an anti-slip rubber pad, which can keep the device stable in complex terrains such as the middle of two insulator rows and the crossarm of the tower, and reduce the impact of vibration on binocular image collection.

[0067] In this solution, balancing frames are set on both sides of the detection frame 11. The auxiliary setting of the balancing frames can increase the stability of the detection frame 11 during detection and movement. At the same time, this solution adopts an extendable balancing telescopic support rod 12. The extension of the balancing telescopic support rod 12 can effectively control the distance between the balancing frames on both sides of the detection frame 11 and the detection frame 11, so that it can be applied to the upper insulator spacing between different electrical connections.

[0068] After the device is stably placed, the drone releases the connection with the device and places the device stably in the middle of the insulator rows on both sides. At this time, the present solution starts and adjusts the multifunctional resistance measuring mechanism 3 so that the magnetic telescopic rod 39 can quickly measure the insulator resistance. The present solution can not only control the magnetic telescopic rods 39 on both sides to swing synchronously to measure the resistance between the insulators, but also control the synchronous design of the magnetic telescopic rods 39. Figure 3 The magnetic telescopic rod 39 shown in the figure can synchronously detect the insulators on both sides. Compared with the prior art that can only measure one insulator in a string, which is inefficient, the present design can synchronously test any group of two insulator strings, which not only increases the convenience of measurement, but also can synchronously take pictures of the insulators on both sides through the balance frames on both sides of the detection frame 11, thereby increasing the efficiency of insulator detection;

[0069] Furthermore, through the setting of the clamping plate 34 in the present solution, the sliding distance of the clamping plate 34 on the guide limit shaft 36 can be controlled by a motor, and the sliding of the clamping plate 34 can synchronously control the arc-shaped tooth screw block 35 that slides symmetrically on the guide limit shaft 36 to change the measurement interval, so that the number of different insulator strings can be measured, which is not limited to the measurement of a single insulator, thereby increasing the applicability of the use of this equipment.

[0070] Step 4: Data result analysis: The host compares the DAC curve and marks the abnormal areas of double-sided signal attenuation (such as internal cracks causing the reflection amplitude to decrease by >50%). Based on the 3D point cloud reconstruction technology, it automatically marks the double-sided damaged areas and calculates the actual area (accuracy ±2cm2).

[0071] Risk classification: Three levels of alarm (yellow / orange / red) are triggered according to the damage depth (>1mm) and area (>5cm2), and displayed in the touch screen heat map.

[0072] Report generation: Upload data to the cloud platform via Wi-Fi / 5G, and automatically generate a PDF report containing a double-sided inspection comparison chart.
