Description

Technical Field

[0001] This invention relates to the field of automated partial discharge sensor technology, and more specifically, to an automated device with a self-calibrating low-power high-frequency partial discharge sensor. Background Technology

[0002] The application of high-frequency partial discharge (PD) sensors in automated conveyor belts is mainly reflected in the monitoring of conveyor belt motors and drive equipment to ensure their normal operation and prevent potential faults. PD sensors monitor the health of the equipment by detecting partial discharge phenomena. When partial discharge occurs inside the motor or drive equipment, ultrasonic or electromagnetic wave signals are generated. These signals are captured by the sensor and converted into electrical signals for processing and analysis, thereby enabling monitoring of the equipment status and fault early warning.

[0003] Currently, automated equipment with self-calibrating low-power high-frequency partial discharge (PD) sensors has the following shortcomings in use: Existing automated equipment with self-calibrating low-power high-frequency PD sensors is generally located in complex electromagnetic environments. High-frequency sensors are susceptible to electromagnetic interference from other equipment. In practical applications, vibration on automated conveyor belts can negatively affect the performance of high-frequency PD sensors, mainly manifested in signal interference and distortion. Vibration may cause changes in the amplitude, frequency, and phase of the signal received by the sensor, thus affecting the accuracy of the measurement. Furthermore, changes in temperature and humidity may affect sensor performance, and automated equipment may be deployed in various environments, affecting reliability and other issues.

[0004] Existing automated devices with self-calibrating low-power high-frequency partial discharge sensors have the aforementioned problems. In view of this, we propose an automated device with a self-calibrating low-power high-frequency partial discharge sensor. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] 1. In an automated device with a self-calibrating low-power high-frequency partial discharge sensor according to the present invention, the automatic telescopic rod retracts after operation, driving the connecting plate to move. The movement of the connecting plate causes the insertion rod to slide in the control box, thereby pushing the multi-section rod to drive the two inner temperature control ring plates and the top ring to move. After the inner temperature control ring plates and the top ring move, they can drive the support rod to move. Under the push of multiple support rods, the shielding aluminum foil cover begins to unfold. When it unfolds to a predetermined position, it stops. At the same time, under the movement of the inner temperature control ring plates, the anti-interference bridge can slide and swing along the groove to unfold. This is beneficial for the use of the high-frequency partial discharge sensor, reducing the impact of external temperature and humidity changes on the sensor, and further improving the overall performance and lifespan of the automated device with the self-calibrating low-power high-frequency partial discharge sensor.

[0020] 2. In an automated device with a self-calibrating low-power high-frequency partial discharge sensor according to the present invention, the rubber wheel in contact with the conveyor belt is driven, causing the crossbeam frame and the limiting rod to move. The limiting rod moves and abuts against the spring. After the crossbeam frame moves, it drives the piston block to move, thereby allowing the piston block to move in the cylinder and abut against the liquid. The internal gas of the cylinder pushes the piston rod to move in the piston cylinder. As gravity and downward thrust cancel each other out, the control top plate can move slightly, thereby driving the support frame to maintain the stability of the mounting plate, further ensuring the stability of the sensor. This effectively avoids the sensor being affected by vibration when installed on the automated equipment. It is beneficial to reduce electromagnetic interference to the sensor when using the high-frequency partial discharge sensor, avoid the damage to the sensor performance caused by vibration of the automated equipment after the sensor is rigidly installed, improve the stability of signal reception, and ensure accuracy.

[0021] 3. In an automated device with a self-calibrating low-power high-frequency partial discharge sensor according to the present invention, after the micro push rod is operated and extends, it pushes the fine-tuning rod to move. After the fine-tuning rod moves, it slides and rises within the limiting port, thereby driving the strip slide rod in the position calibration component to move. After the strip slide rod moves, it slides within the guide slot, thereby driving the linkage plate to move, and further driving the control box to slide on the guide slot, thereby calibrating the high-frequency partial discharge sensor.

Detailed Implementation

[0033] This invention provides an automated device with a self-calibrating, low-power, high-frequency partial discharge sensor, which solves the following problems: In automated devices, which are often located in complex electromagnetic environments, high-frequency sensors are easily affected by electromagnetic interference from other devices. Furthermore, in practical applications, vibration on automated conveyor belts negatively impacts the performance of high-frequency partial discharge sensors, primarily manifesting as signal interference and distortion. Vibration can cause changes in the amplitude, frequency, and phase of the signal received by the sensor, thus affecting measurement accuracy. Furthermore, changes in temperature and humidity can affect sensor performance, and automated devices may be deployed in various environments, impacting reliability.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] An automated device for a self-calibrating low-power high-frequency partial discharge sensor, as shown in Figures 1-8, includes a main body 1. A conveyor body 2 is mounted at one end of the main body 1. An automated conveying assembly 551 is mounted on the upper end of the conveyor body 2. The automated conveying assembly 551 includes a conveyor frame 8 fixedly mounted on the upper end of the conveyor body 2. A mounting frame 12 is fixedly connected to the inner side wall of the conveyor frame 8. A guide block 26 is fixedly connected to one end of the mounting frame 12. Two control boxes 6 are slidably mounted on one end of the guide block 26. A calibration shielding protection assembly 552 is provided on one side of the two control boxes 6. The calibration shielding protection assembly 552 includes components disposed in the two control boxes. On one side of the control box 6, a mounting plate 40 is attached. A sensor 21 is fixedly connected to one end of the mounting plate 40. An external wiring 32 is fixedly connected to one side of the sensor 21. The external wiring 32 is interlocked with the mounting plate 40. A shielding aluminum foil cover 4 is fixedly connected to one side of the mounting plate 40. A calibration shielding protection assembly 552 is movably installed at the bottom of both control boxes 6. The calibration shielding protection assembly 552 includes multi-section rods 35 movably installed at the bottom of both control boxes 6. The two multi-section rods 35 pass through one end of the control box 6 and are connected to a top ring 24. Two inner-lined temperature control rings 14 are slidably fitted onto the outer surfaces of the two multi-section rods 35. Both control boxes 6 have interlocking... The anti-shake adjustment component 553, the position calibration component 555 is slidably installed on the inner side of the guide slot block 26, the signal amplifier 13 is installed on one side of the conveyor frame 8, the lower part of one of the control boxes 6 is equipped with a take-up and release adaptation component 556, the bottom end of the conveyor frame 8 is equipped with a drive motor 22, the inner sides of the two control boxes 6 are interlaced with a stable mounting component 554, two anti-interference bridges 34 are rotatably connected to one side of the mounting plate 40, the inner walls of the two inner lining temperature control ring plates 14 are provided with grooves 37, the anti-interference bridges 34 are slidably arranged with the grooves 37, and multiple support rods 20 are rotatably connected to the outer surface of the top ring 24 and the inner lining temperature control ring plate 14 in a ring. All are rotatably connected to the inner wall of the shielding aluminum foil cover 4. The stable installation assembly 554 includes multiple piston cylinders 27 opened on one side close to each other of the two control boxes 6. Piston rods 23 are inserted into the inner side of each of the multiple piston cylinders 27. The upper ends of the multiple piston rods 23 are connected to the control top plate 7. The bottom end of the control top plate 7 is fixedly connected to the support frame 44. The support frame 44 is fixedly connected to the mounting plate 40. Cylinders 33 are provided at the lower part of the two control boxes 6. Piston blocks 25 correspond to cylinders 33. Multiple piston rods 23 are used in conjunction with cylinders 33. The inner side of the conveyor frame 8 is respectively installed with a conveyor belt 3 and a side plate 41. The side plate 41 is located on the upper surface of the conveyor belt 3.

[0036] The above technical solution utilizes an automatic telescopic rod 28 that retracts after operation, driving the connecting plate 30 to move. The movement of the connecting plate 30 causes the insertion rod 29 to slide within the control box 6, thereby pushing the multi-section rod 35 to move the two inner-lined temperature-controlled ring plates 14 and the top ring 24. The movement of the inner-lined temperature-controlled ring plates 14 and the top ring 24 then drives the support rod 20 to move. Driven by the multiple support rods 20, the shielding aluminum foil cover 4 begins to unfold. When it unfolds to a predetermined position, it stops. Simultaneously, the movement of the inner-lined temperature-controlled ring plates 14 allows the anti-interference bridge 34 to slide and swing along the groove 37, causing the sensor 21 to start working. When vibration occurs in the automated equipment during operation, the rubber wheel 17 in contact with the conveyor belt 3 will be driven, causing the crossbeam frame 16 and the limit switch to move. When rod 18 moves, the limiting rod 18 moves and contacts spring 19. After the crossbeam frame 16 moves, it drives the piston block 25 to move, so that the piston block 25 moves in the cylinder 33 and contacts the liquid. Thus, the internal gas of the cylinder 33 pushes the piston rod 23 to move in the piston cylinder 27. As gravity and downward thrust cancel each other out, the control top plate 7 can move slightly, thereby driving the support frame 44 to keep the mounting plate 40 stable, further ensuring the stability of sensor 21. This effectively avoids the sensor 21 being affected by vibration when installed on automated equipment. It is beneficial for the use of high-frequency partial discharge sensors, which can effectively reduce the interference of the electromagnetic environment on the sensor, avoid the damage to the sensor performance caused by the vibration of automated equipment after the sensor is rigidly installed, improve the stability of signal reception, and ensure accuracy.

[0037] A further technical solution includes a vibration adjustment component 553 comprising a piston block 25 inserted into the lower part of the control box 6, a crossbeam frame 16 inserted into the lower part of the piston block 25, rubber wheels 17 rotatably mounted at both ends of the crossbeam frame 16, two limit rods 18 rotatably connected to the upper surface of the crossbeam frame 16, and springs 19 fitted onto the outer surfaces of the two limit rods 18. The two limit rods 18 are respectively slidably inserted into the control box 6. The position calibration component 555 includes a strip slide rod 39 slidably disposed inside the guide groove block 26, a linkage plate 31 movably connected to one end of the strip slide rod 39, and the linkage plate 31 connected to the control box 6. The inner wall of the conveyor frame 8 is provided with... The modulation chamber 15 has a miniature push rod 11 installed inside it. A limit opening 10 is opened on the inner wall of the modulation chamber 15. One end of the strip slide rod 39 is rotatably connected to a fine adjustment rod 9. The fine adjustment rod 9 is interposed with the limit opening 10. The output end of the miniature push rod 11 is rotatably connected to the fine adjustment rod 9. The retraction and extension adaptation component 556 includes an automatic telescopic rod 28 installed at the bottom of the control box 6. The extended end of the automatic telescopic rod 28 is fixedly connected to a connecting plate 30. One end of the multi-section rod 35 is fixedly connected to an insertion rod 29. One side of the connecting plate 30 is fixedly connected to the insertion rod 29. The outer surface of the multi-section rod 35 is provided with multiple baffles 36 that cooperate with the inner lining temperature control ring plate 14.

[0038] The above technical solution involves turning on the switch of the micro push rod 11 via an external controller. When the micro push rod 11 is turned on, it extends and pushes the fine-tuning rod 9 to move. After the fine-tuning rod 9 moves, it slides and rises within the limit port 10, thereby driving the strip slide rod 39 in the position calibration component 555 to move. After the strip slide rod 39 moves, it slides within the guide slot 26, causing the linkage plate 31 to move. This further causes the control box 6 to slide on the guide slot 26, thus calibrating the high-frequency partial discharge sensor. This is beneficial for the high-frequency partial discharge sensor to reduce the impact of external temperature and humidity changes on the sensor during use, and further improves the overall performance and lifespan of the automated equipment with self-calibrating low-power high-frequency partial discharge sensor.

[0039] The specific method of using this invention is as follows: After the automated equipment is running, the automatic telescopic rod 28 in the retraction and adaptation assembly 556 is opened by the external controller. After the automatic telescopic rod 28 operates, it retracts and drives the connecting plate 30 to move. Under the movement of the connecting plate 30, the insertion rod 29 can slide in the control box 6, thereby pushing the multi-section rod 35 to drive the two inner lining temperature control ring plates 14 and the top ring 24 to move. After the inner lining temperature control ring plates 14 and the top ring 24 move, they can drive the support rod 20 to move. Under the push of the multiple support rods 20, the shielding aluminum foil cover 4 starts to unfold. When it unfolds to the predetermined position, it stops. At the same time, under the movement of the inner lining temperature control ring plates 14, the anti-interference bridge 34 can slide and swing along the groove 37 to unfold, so that the sensor 21 starts to work. When there is vibration in the automated equipment during operation, the rubber wheel 17 in contact with the conveyor belt 3 will be driven, which will drive the crossbeam frame 16 and the limit rod 18 to move. The limit rod 18 moves and abuts against the spring 19, and the crossbeam frame 16 moves. After the piston is moved, the piston block 25 moves, causing the piston block 25 to move and come into contact with the liquid in the cylinder 33. The internal gas of the cylinder 33 pushes the piston rod 23 to move in the piston cylinder 27. As gravity and downward thrust cancel each other out, the control top plate 7 can move slightly, thereby driving the support frame 44 to keep the mounting plate 40 stable, further ensuring the stability of the sensor 21 and effectively avoiding the sensor 21 being affected by vibration when installed on the automated equipment. When the high-frequency partial discharge sensor needs fine adjustment, the switch of the micro push rod 11 can be turned on from the external controller. After the micro push rod 11 is turned on, it extends and pushes the fine adjustment rod 9 to move. After the fine adjustment rod 9 moves, it slides and rises in the limit port 10, thereby driving the strip slide rod 39 in the position calibration component 555 to move. After the strip slide rod 39 moves, it slides in the guide slot 26, causing the linkage plate 31 to move, further driving the control box 6 to slide on the guide slot 26, so as to calibrate the high-frequency partial discharge sensor.

[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
