A porcelain insulator condition identification device and method

Abstract

This invention discloses a porcelain insulator status identification device and method, relating to the field of porcelain insulator detection technology. It includes a mounting base and a positioning frame with a displacement and reversing component mounted on it. By using the displacement and reversing component, a first servo motor drives a lead screw, causing a slider limited by a limiting groove to move along the lead screw. When the slider moves upward relative to the mounting base, one end of a telescopic rod swings clockwise relative to the positioning frame, causing a third transmission bevel gear to rotate counterclockwise relative to the connecting chamber. This ensures that when the probe moves from one side of the porcelain insulator to an oblique position above it, its lens always faces the porcelain insulator. This allows for multi-point detection of the porcelain insulator from an oblique position, eliminating the need for repeated adjustments to the position of the drone and the moving gimbal, simplifying operation and improving detection efficiency.

Description

Technical Field

[0001] This invention relates to the field of porcelain insulator testing technology, specifically to a porcelain insulator condition identification device and method. Background Technology

[0002] Currently, the common method for conducting condition inspections of porcelain insulators is to use drones equipped with infrared spectrometers. The drone flies and hovers at a suitable position to the side of the porcelain insulator, using the infrared spectrometer to emit infrared detection light waves and receive the reflected spectral information from the surface of the porcelain insulator. By analyzing and judging the spectral characteristic bands, absorption peaks, and waveform changes, the condition defects of the porcelain insulator surface, such as contaminant components, aging of the surface material, moisture deterioration, and insulation performance degradation, are identified, enabling long-distance, non-contact on-site condition inspection and hazard identification of porcelain insulators for transmission lines.

[0003] Currently, when using drones equipped with infrared spectrometers for porcelain insulator condition identification, in order to improve detection accuracy, it is necessary to change the spatial position of the detection probe and perform multi-point sampling detection on different parts of the porcelain insulator to enrich the data dimensions and improve the reliability of the detection results. In the conventional method, when adjusting the position and attitude of the probe, it is necessary to first rely on the overall flight movement of the drone to complete the coarse adjustment of the probe position, and then use the gimbal movement to perform secondary angle calibration of the probe orientation. The entire adjustment process is carried out step by step, with cumbersome coordination, complex operation procedures, long alignment time, and multiple adjustments are prone to causing hovering attitude fluctuations, affecting the stability of infrared spectral sampling and detection efficiency. Summary of the Invention

[0008] As a further embodiment of the present invention: the center of the second connecting shaft is coaxial with the centers of the third transmission bevel gear and the first transmission bevel gear.

[0009] As a further embodiment of the present invention: the protective unit includes a turntable installed on the side of the U-shaped frame away from the second servo motor and connected to the first connecting shaft. A locking pin is installed at the end of the turntable away from the first connecting shaft. A straight groove slide rail is sleeved on the outer side of the locking pin. A limiting block is provided on one side of the U-shaped frame above the turntable. A second piston cylinder is installed on the top of the limiting block. An insert rod is provided on the outer side of the straight groove slide rail, penetrating the limiting block and extending to the inner side of the second piston cylinder.

[0013] As a further aspect of the present invention: the inner wall diameter of the second piston cylinder is larger than the inner wall diameter of the first piston cylinder, and the volumes of the second piston cylinder and the first piston cylinder are equal.

[0014] This invention also discloses a method for identifying the state of porcelain insulators, which uses the aforementioned porcelain insulator state identification device and includes the following steps: S1: First, install the device on the bottom of the drone using the mounting bracket. Then, move the device to the side of the porcelain insulator to be inspected by moving the device with the help of the drone. At this time, the positioning frame is in a horizontal state. S2: Start the second servo motor, which drives the first connecting shaft to rotate 90 degrees to make the positioning frame change from a horizontal state to a vertical state. At this time, the probe will lose the protection of the protection unit. The probe is finely adjusted by the operation of the driver and the movable pan-tilt unit so that the probe is aligned with one side of the porcelain insulator. The working state of the porcelain insulator is detected by the cooperation between the probe and the main body of the infrared spectrometer. S3: Start the first servo motor, which drives the screw to move the slider limited by the limit groove along the screw. When the slider moves upward relative to the mounting base, one end of the telescopic rod will swing clockwise relative to the positioning frame. At this time, the other end of the telescopic rod will rotate clockwise relative to the connecting chamber. S4: The telescopic rod extends during the swinging process. During this process, the first transmission bevel gear rotates with the swinging of the telescopic rod. At this time, the first transmission bevel gear drives the third transmission bevel gear to rotate through the second transmission bevel gear. This allows the third transmission bevel gear to rotate counterclockwise relative to the connecting chamber. The third transmission bevel gear then drives the second connecting shaft to swing. This allows the second connecting shaft to drive the U-shaped baffle to swing when the slider moves upward. This ensures that when the probe moves from one side of the porcelain insulator to above the porcelain insulator, its lens always faces the porcelain insulator. Similarly, when the slider moves downward along the lead screw, the probe will detect the porcelain insulator from below the porcelain insulator.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a shifting and reversing component, the operation of the lead screw driven by the first servo motor causes the slider limited by the limit groove to move along the lead screw. When the slider moves upward relative to the mounting base, one end of the telescopic rod will swing clockwise relative to the positioning frame. At this time, the first transmission bevel gear will drive the third transmission bevel gear to rotate through the second transmission bevel gear. This allows the third transmission bevel gear to rotate counterclockwise relative to the connecting chamber. As the slider moves upward, the second connecting shaft drives the U-shaped baffle to swing, so that when the probe moves from one side of the porcelain insulator to the obliquely above the porcelain insulator, its lens always faces the porcelain insulator. This allows the state of the porcelain insulator to be detected from the obliquely above the porcelain insulator, realizing multi-point detection of the porcelain insulator. In this process, there is no need to repeatedly adjust the position of the drone and the moving gimbal, the operation is simple, and the detection efficiency is improved. 2. By setting up a protective unit, when the first connecting shaft rotates relative to the U-shaped frame, it will drive the turntable to rotate. At this time, the turntable drives the insertion rod, which is limited by the limit block, to move upward through the locking pin. This causes the insertion rod to push the piston plate to move. At this time, the solution inside the second piston cylinder will be squeezed by the piston plate. The solution inside the second piston cylinder will then enter the first piston cylinder through the hose. As the solution inside the first piston cylinder increases, the piston rod will move relative to the first piston cylinder. This causes the piston rod to drive the first rack and side plate away from the U-shaped baffle. The probe moves in the opposite direction, with the first rack driving the second rack to move in the opposite direction via a reversing gear. This causes the side plates on both sides of the U-shaped baffle to move away from the U-shaped baffle, thus removing the obstruction of the probe by the base plate and side plates. This allows the probe to be protected according to its working status. The protection and operation are automatically switched with the attitude of the positioning frame throughout the entire process, without the need for separate operation of the protective cover. The inspection process is simpler and suitable for automated continuous detection. It also avoids the impact of scratches and dust accumulation on the mirror surface during flight, which would affect the accuracy of spectral acquisition. Attached Figure Description

[0020] Please see Figures 1 to 8 In this embodiment of the invention, a porcelain insulator status identification device includes a mounting base 1, a U-shaped frame 2 mounted on the bottom of the mounting base 1, a first connecting shaft 3 rotatably connected to both sides of the U-shaped frame 2 via bearings, a positioning frame 8 located inside the U-shaped frame 2 connected to one end of the first connecting shaft 3, a first servo motor 4 mounted on one end of the positioning frame 8, a displacement reversing component mounted on the positioning frame 8, a U-shaped baffle 11 connected to the positioning frame 8 via the displacement reversing component, a driver 27 mounted on the top of the U-shaped baffle 11, a movable gimbal 30 located inside the U-shaped baffle 11 connected to the bottom end of the driver 27, a probe 29 mounted on one end of the movable gimbal 30, a protective unit connected to the first connecting shaft 3 provided on the outside of the U-shaped baffle 11, a second servo motor 5 connected to the first connecting shaft 3 provided on the outside of the U-shaped frame 2, and an infrared spectrometer body 7 mounted on one side of the U-shaped frame 2. The shifting and reversing component includes a lead screw 10 connected to the output end of the first servo motor 4 and located inside the positioning frame 8. Limiting grooves 9 are formed on both sides of the positioning frame 8. A slider 14 extending to the outside of the positioning frame 8 is movably sleeved on the lead screw 10. The bottom end of the slider 14 is rotatably connected to a connecting chamber 16 via a bearing. Positioning frames 13 are installed on both sides of the positioning frame 8 above the limiting grooves 9. A telescopic rod 17 is rotatably connected to one side of the positioning frame 13 via a rotating shaft. Connecting chambers 16 and telescopic rods 17 are installed on both sides of the slider 14. The bottom end of the telescopic rod 17 is rotatably connected to the connecting chamber 16 via a rotating shaft. One end of the rotating shaft connecting the telescopic rod 17 and the connecting chamber 16 is provided with a first transmission bevel gear 18 located inside the connecting chamber 16. The inner wall of the connecting chamber 16 is rotatably connected to a second transmission bevel gear 19 via a rotating shaft. The bottom end of the slider 14 is rotatably connected to a second connecting shaft 15 via a bearing. One end of the second connecting shaft 15 near the connecting chamber 16 is provided with a third transmission bevel gear 20 located inside the connecting chamber 16. The other end of the second connecting shaft 15 is fixedly connected to the U-shaped baffle 11.

[0021] The telescopic rod 17 is connected to the second connecting shaft 15 via the first transmission bevel gear 18, the second transmission bevel gear 19, and the third transmission bevel gear 20. The diameters of the first transmission bevel gear 18, the second transmission bevel gear 19, and the third transmission bevel gear 20 are equal. The slider 14 is provided with a threaded hole that matches the lead screw 10. The slider 14 is slidably connected to the positioning frame 8 via the limiting slide groove 9. The center of the second connecting shaft 15 is coaxial with the centers of the third transmission bevel gear 20 and the first transmission bevel gear 18.

[0022] In this embodiment: First, the device is installed on the bottom of the drone via the mounting base 1. The drone moves the device to the side of the porcelain insulator to be tested. At this time, the positioning frame 8 is in a horizontal state. The second servo motor 5 is started, which drives the first connecting shaft 3 to rotate 90 degrees, so that the positioning frame 8 changes from a horizontal state to a vertical state. At this time, the probe 29 loses the protection of the protective unit. The operation of the driver 27 and the movable gimbal 30 is used to fine-tune the probe 29 so that the probe 29 is aligned with one side of the porcelain insulator. The probe 29 and the infrared spectrometer body 7 work together to detect the state of the porcelain insulator in working condition. Then, the first servo motor 4 is started, which drives the operation of the lead screw 10 to move the slider 14, which is limited by the limit groove 9, along the lead screw 10. When the slider 14 moves upward relative to the mounting base 1, one end of the telescopic rod 17 swings clockwise relative to the positioning frame 13. At this time, the other end of the telescopic rod 17 rotates clockwise relative to the connecting chamber 16, and at the same time, the extension... During the swinging motion of the telescopic rod 17, the first transmission bevel gear 18 rotates along with the swing of the telescopic rod 17. At this time, the first transmission bevel gear 18 drives the third transmission bevel gear 20 to rotate through the second transmission bevel gear 19. This causes the third transmission bevel gear 20 to rotate counterclockwise relative to the connecting chamber 16. The third transmission bevel gear 20 then drives the second connecting shaft 15 to swing. This causes the second connecting shaft 15 to swing the U-shaped baffle 11 when the slider 14 moves upward. This ensures that when the probe 29 moves from one side of the porcelain insulator to an oblique position above the porcelain insulator, its lens always faces the porcelain insulator. This allows for detection of the porcelain insulator's condition from an oblique position above the porcelain insulator. Similarly, when the slider 14 moves downward along the lead screw 10, the probe 29 detects the porcelain insulator from an oblique position below the porcelain insulator. This enables multi-point detection of the porcelain insulator without the need for repeated adjustments to the positions of the drone and the movable gimbal 30. The operation is simple and the detection efficiency is improved.

[0023] Please refer to this carefully. Figure 2 , Figure 5 , Figure 7 , Figure 8 The protective unit includes a turntable 31 installed on the side of the U-shaped frame 2 away from the second servo motor 5 and connected to the first connecting shaft 3. A locking pin 34 is installed at the end of the turntable 31 away from the first connecting shaft 3. A straight groove slide rail 33 is sleeved on the outside of the locking pin 34. A limiting block 35 is provided on one side of the U-shaped frame 2 above the turntable 31. A second piston cylinder 36 is installed on the top of the limiting block 35. An insert rod 32 is provided on the outside of the straight groove slide rail 33, penetrating the limiting block 35 and extending to the inside of the second piston cylinder 36. A piston plate 6 is provided at the top of the insert rod 32, located inside the second piston cylinder 36. The protective unit also includes side plates 12 slidably connected to both sides of the U-shaped baffle 11. A first rack 24 and a second rack 25 are respectively installed on the top of the side plates 12 on both sides of the U-shaped baffle 11. A reversing gear 26 that meshes with the first rack 24 and the second rack 25 is provided on the top of the U-shaped baffle 11. A support frame 21 located outside the first rack 24 is installed on the top of the U-shaped baffle 11. A first piston cylinder 23 is installed at one end of the support frame 21. A piston rod 22 extending to the outside of the first piston cylinder 23 and connected to the first rack 24 is inserted into the inside of the first piston cylinder 23. A bottom plate 28 is installed at the bottom of the side plates 12.

[0024] The first piston cylinder 23 is equipped with a flexible hose 37 at the end away from the piston rod 22. The second piston cylinder 36 is connected to the first piston cylinder 23 through the flexible hose 37. The center of the turntable 31 is coaxial with the center of the first connecting shaft 3. The center of the turntable 31 is misaligned with the center of the locking pin 34. The inner diameter of the second piston cylinder 36 is larger than the inner diameter of the first piston cylinder 23. The volumes of the second piston cylinder 36 and the first piston cylinder 23 are equal.

[0025] In this embodiment: when the first connecting shaft 3 rotates relative to the U-shaped frame 2, it will drive the turntable 31 to rotate. At this time, the turntable 31 drives the insertion rod 32, which is limited by the limiting block 35, to move upward through the locking pin 34, thereby causing the insertion rod 32 to push the piston plate 6 to move. At this time, the solution inside the second piston cylinder 36 will be squeezed by the piston plate 6, and the solution inside the second piston cylinder 36 will enter the first piston cylinder 23 through the hose 37. As the solution inside the first piston cylinder 23 increases, the piston rod 22 will move relative to the first piston cylinder 23, thereby causing the piston rod 22 to drive the first rack 24 and the side plate 12 away from the U-shaped stop. The plate 11 moves in the direction of the movement. During this process, the first rack 24 drives the second rack 25 to move in the opposite direction through the reversing gear 26. This allows the side plates 12 on both sides of the U-shaped baffle 11 to move away from the U-shaped baffle 11. This allows the base plate 28 and the side plates 12 to no longer block the probe 29. Thus, the probe 29 can be protected according to its working state. The protection and operation are automatically switched with the attitude of the positioning frame 8 throughout the entire process. There is no need to operate the protective cover separately. The inspection process is simpler and suitable for automated continuous detection. It also avoids the impact of mirror scratches and dust accumulation on the spectral acquisition accuracy during flight.

[0026] The following describes a method for identifying the condition of porcelain insulators, based on the aforementioned porcelain insulator condition identification device, specifically including the following steps: S1: First, install the device on the bottom of the drone using the mounting base 1. Move the device to the side of the porcelain insulator to be tested by moving the device with the help of the drone. At this time, the positioning frame 8 is in a horizontal state. S2: Start the second servo motor 5. The second servo motor 5 drives the first connecting shaft 3 to rotate 90 degrees, so that the positioning frame 8 changes from a horizontal state to a vertical state. When the first connecting shaft 3 rotates relative to the U-shaped frame 2, it will drive the turntable 31 to rotate. At this time, the turntable 31 drives the insertion rod 32, which is limited by the limit block 35, to move upward through the locking pin 34. This causes the insertion rod 32 to push the piston plate 6 to move. At this time, the solution inside the second piston cylinder 36 will be squeezed by the piston plate 6. The solution inside the second piston cylinder 36 will then enter the first piston cylinder 23 through the hose 37. As the solution inside the first piston cylinder 23 increases, the piston rod 22 will move relative to the first piston cylinder 23. This causes the piston rod 22 to drive the first rack 24 and the side plate 12 to move away from the U-shaped baffle 11. During this process, the first... A rack 24 drives a second rack 25 to move in the opposite direction via a reversing gear 26. This causes the side plates 12 on both sides of the U-shaped baffle 11 to move away from the U-shaped baffle 11. This removes the obstruction of the probe 29 by the base plate 28 and the side plates 12. The probe 29 can be protected according to its working state. The protection and operation are automatically switched with the posture of the positioning frame 8 throughout the entire process. There is no need to operate the protective cover separately. The inspection process is simpler and suitable for automated continuous detection. It also avoids the impact of mirror scratches and dust accumulation on the spectral acquisition accuracy during flight. The probe 29 is finely adjusted by the operation of the driver 27 and the movable gimbal 30 so that the probe 29 is aligned with one side of the porcelain insulator. The working state of the porcelain insulator is detected by the cooperation between the probe 29 and the infrared spectrometer body 7. S3: Start the first servo motor 4. Drive the operation of the lead screw 10 through the first servo motor 4 to make the slider 14, which is limited by the limit groove 9, move along the lead screw 10. When the slider 14 moves upward relative to the mounting base 1, one end of the telescopic rod 17 will swing clockwise relative to the positioning frame 13. At this time, the other end of the telescopic rod 17 will rotate clockwise relative to the connecting chamber 16. S4: The telescopic rod 17 extends during the swinging process. During this process, the first transmission bevel gear 18 rotates with the swinging of the telescopic rod 17. At this time, the first transmission bevel gear 18 drives the third transmission bevel gear 20 to rotate through the second transmission bevel gear 19. This allows the third transmission bevel gear 20 to rotate counterclockwise relative to the connecting chamber 16. At this time, the third transmission bevel gear 20 drives the second connecting shaft 15 to swing. This allows the second connecting shaft 15 to drive the U-shaped baffle 11 to swing when the slider 14 moves upward. This ensures that when the probe 29 moves from one side of the porcelain insulator to the upper side of the porcelain insulator, its lens always faces the porcelain insulator. Similarly, when the slider 14 moves downward along the screw 10, the probe 29 will detect the porcelain insulator from the lower side.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method for identifying the state of a porcelain insulator, characterized in that, The porcelain insulator status identification device according to any one of claims 1-9 includes the following steps: S1: First, install the device on the bottom of the drone using the mounting base (1), and move the device to the side of the porcelain insulator to be tested by the drone. At this time, the positioning frame (8) is in a horizontal state. S2: Start the second servo motor (5), and drive the first connecting shaft (3) to rotate 90 degrees to make the positioning frame (8) change from a horizontal state to a vertical state. At this time, the probe (29) will lose the protection of the protection unit. The probe (29) is finely adjusted by the operation of the driver (27) and the movable gimbal (30) so that the probe (29) is aligned with one side of the porcelain insulator. The working state of the porcelain insulator is detected by the cooperation of the probe (29) and the infrared spectrometer body (7). S3: Start the first servo motor (4), and drive the screw (10) to move the slider (14) which is limited by the limiting groove (9) along the screw (10). When the slider (14) moves upward relative to the mounting base (1), one end of the telescopic rod (17) will swing clockwise relative to the positioning frame (13). At this time, the other end of the telescopic rod (17) will rotate clockwise relative to the connecting chamber (16). S4: The telescopic rod (17) extends during the swinging process. During this process, the first transmission bevel gear (18) will rotate with the swinging of the telescopic rod (17). At this time, the first transmission bevel gear (18) will drive the third transmission bevel gear (20) to rotate through the second transmission bevel gear (19). This allows the third transmission bevel gear (20) to rotate counterclockwise relative to the connecting chamber (16). At this time, the third transmission bevel gear (20) will drive the second connecting shaft (15) to swing. This allows the second connecting shaft (15) to drive the U-shaped baffle (11) to swing when the slider (14) moves upward. This allows the probe (29) to move from one side of the porcelain insulator to the upper side of the porcelain insulator, so that its lens always faces the porcelain insulator. Similarly, when the slider (14) moves downward along the screw (10), the probe (29) will detect the porcelain insulator from the lower side of the porcelain insulator.
