Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to an adaptive conveying device for a corrugated pipe cleaning line based on industrial vision. Background Technology

[0002] With the rapid development of my country's power industry and the continuous advancement of ultra-high voltage (UHV) transmission and smart grid construction, high-voltage power grids have become a core infrastructure for ensuring energy security and supporting economic and social development. Their coverage is constantly expanding, and voltage levels are continuously increasing, placing stringent requirements on the reliability, stability, and adaptability of key components. High-voltage power grid corrugated pipes, as a crucial core component of the power grid system, are widely used in key scenarios such as high-voltage switchgear, buried high-voltage cable protection, and substation outgoing line networks. They primarily undertake important functions such as displacement compensation, sealing protection, and cable protection, directly affecting the safe and stable operation and power supply quality of the high-voltage power grid. Currently, high-voltage power grids... Corrugated pipe cleaning often employs traditional mechanized cleaning line operations. While these lines achieve initial automation of the cleaning process, their accompanying conveying devices have significant technological shortcomings. Furthermore, they lack industrial vision technology as a core monitoring and control support, making it difficult to meet the demands of intelligent cleaning. Existing conveying devices are mostly rigid structures with fixed rotation speeds and clamping distances, lacking adaptive adjustment capabilities. High-voltage power grid corrugated pipes come in various specifications, and some exhibit irregular shapes and uneven surfaces, severely impacting cleaning accuracy and efficiency. Therefore, to facilitate the cleaning of corrugated pipes, an adaptive conveying device based on industrial vision is needed.

[0003] Traditional corrugated pipe conveying devices typically employ high-pressure spray cleaning. However, the conveying speed of the corrugated pipe is difficult to precisely match with the operating rhythm of the cleaning mechanism. When the conveying speed is too fast, impurities on the surface of the corrugated pipe cannot be thoroughly cleaned. When the conveying speed is too slow, the cleaning efficiency is low, making cleaning difficult. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive conveying device for a corrugated pipe cleaning line based on industrial vision, so as to solve the problem mentioned in the background art that the conventional high-pressure spray cleaning method makes it difficult to accurately match the conveying speed of the corrugated pipe with the working rhythm of the cleaning mechanism, which is not convenient for cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The device includes a fixed control unit, an internal conveying unit comprising two conveyor belts with a replacement rack between them, an external industrial vision monitoring unit, an internal immersion cleaning unit comprising a collection plate with an internal immersion cylinder fitted over the replacement rack, and an internal spray washing unit comprising a fixed base plate with a spray washing cylinder fixedly attached to the top of the base plate and multiple circumferentially distributed spray washing plates fixedly attached to the inner wall of the spray washing cylinder.

[0006] Preferably, the fixed control unit includes a fixed bracket, a drive assembly is fixedly connected inside the fixed bracket, a main control wheel is rotatably connected to the outer wall of the fixed bracket, the main control wheel is fixedly connected to the drive assembly inside the fixed bracket, a drive wheel is rotatably connected to the outer wall of the fixed bracket, and a connecting belt drives the main control wheel and the drive wheel.

[0007] Preferably, the fixed bracket has an internally rotatably connected drive wheel assembly, which is fixedly connected to the drive wheel. The fixed bracket also has an internally rotatably connected mating wheel assembly. The top of the fixed bracket has two fixed slots, each of which has an inner frame fixedly connected inside. Each of the two inner frames has a support roller rotatably connected at equal intervals inside.

[0008] Preferably, both conveyor belts are fitted onto the drive wheel assembly and the mating wheel assembly, and constraint blocks are fixedly connected to both conveyor belts at equal intervals. The replacement frame is provided with a docking slot, and the replacement frame is engaged with the corresponding constraint block through the docking slot.

[0009] Preferably, the replacement frame has multiple outwardly extending grooves distributed in a circular pattern. Each outwardly extending groove has a sliding block slidably connected inside it. Each sliding block has a spring fixedly connected to it, and an inner jacking rod is fixedly connected to the top of each sliding block.

[0010] Preferably, the industrial vision monitoring unit includes an external fixed bracket, which is fixed to the outer wall of the fixed bracket. An industrial vision position monitor is fixed to the external fixed bracket and electrically connected to an external control component. A position matching block is fixed to the replacement bracket, and the industrial vision position monitor performs visual monitoring on the position matching block. An industrial vision dimension monitor is fixed to the inner wall of the fixed bracket and electrically connected to an external control component. The industrial vision dimension monitor performs visual monitoring on the size of the corrugated pipe inside the replacement bracket.

[0011] Preferably, the liquid collection plate is fixed to the inner wall of the fixed bracket, the side of the liquid collection plate is provided with multiple stabilizing grooves, the bottom of the liquid collection plate is provided with multiple telescopic sleeve holes, the soaking cylinder is slidably connected to the telescopic sleeve holes along the stabilizing grooves, and the bottom of the liquid collection plate is fixedly connected to a bottom mounting bracket.

[0012] Preferably, a telescopic cylinder is fixedly connected to the bottom of the base frame, the telescopic cylinder is electrically connected to an external control component, the telescopic cylinder is fixedly connected to the soaking cylinder, and a buffer spring is provided between the soaking cylinder and the base frame.

[0013] Preferably, the fixed base plate is slidably connected in the corresponding telescopic sleeve hole, the fixed base plate is fixedly connected to the corresponding telescopic cylinder, and the plurality of spray washing plates are all connected to the external spray washing assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an industrial vision monitoring unit, the industrial vision dimension monitor collects the dimension data of the corrugated pipe inside the replacement frame in real time and transmits it synchronously to the external control components. At the same time, the spray pressure of the spray washing unit, the rotation speed of the spray washing cylinder, and the soaking time of the soaking cleaning unit are adjusted in linkage. By cooperating with the displacement slider, spring and inner jacking rod on the replacement frame, the spacing of the inner jacking rod can be flexibly adjusted according to the inner diameter of the corrugated pipe to be cleaned, so as to achieve stable fixation of the corrugated pipe.

[0015] 2. The system employs a dual cleaning method combining immersion cleaning and rotary spraying. First, the corrugated pipe is completely submerged in the cleaning solution using an immersion tank. This chemical action softens stubborn impurities on the surface, laying the foundation for subsequent spraying. Then, the spraying tank moves upwards, and high-pressure cleaning fluid is used to thoroughly clean the surface and gaps of the corrugated pipe, leaving no blind spots. Compared to traditional single high-pressure spraying, this method provides more comprehensive cleaning coverage and more thorough decontamination. The industrial vision monitoring unit detects the impurities on the placed corrugated pipe and transmits the data to an external control unit for integration. This allows for simultaneous control and balancing of the immersion cleaning and spraying processes, enabling the corrugated pipe to be processed between multiple workstations. This effectively avoids the problem of conventional high-pressure spraying cleaning methods, where the conveying speed of the corrugated pipe is difficult to precisely match with the operating rhythm of the cleaning mechanism, making cleaning difficult.

[0019] This invention provides a technical solution: such as Figure 1 - Figure 11The adaptive conveying device shown includes a fixed control unit 1, inside which is a conveying unit 2. The conveying unit 2 includes two conveyor belts 201, and a replacement frame 203 is provided between the two conveyor belts 201.

[0024] The industrial vision monitoring unit 3 includes an external fixed bracket 301, which is fixed to the outer wall of the fixed bracket 101. An industrial vision position monitor 302 is fixed to the external fixed bracket 301 and is electrically connected to an external control component. A position matching block 303 is fixed to the replacement bracket 203 and the industrial vision position monitor 302 performs visual monitoring on the position matching block 303. An industrial vision dimension monitor 304 is fixed to the inner wall of the fixed bracket 101 and is electrically connected to an external control component. The industrial vision dimension monitor 304 performs visual monitoring on the size of the corrugated pipe inside the replacement bracket 203.

[0025] The liquid collection plate 401 is fixed to the inner wall of the fixed bracket 101. Multiple stabilizing grooves 402 are provided on the side of the liquid collection plate 401. Multiple telescopic sleeve holes 403 are provided at the bottom of the liquid collection plate 401. The soaking cylinder 404 is slidably connected to the telescopic sleeve hole 403 along the stabilizing groove 402. A bottom mounting bracket 405 is fixed to the bottom of the liquid collection plate 401.

[0026] A telescopic cylinder 406 is fixedly connected to the bottom of the base frame 405. The telescopic cylinder 406 is electrically connected to an external control component. The telescopic cylinder 406 is fixedly connected to the soaking cylinder 404. A buffer spring 407 is provided between the soaking cylinder 404 and the base frame 405.

[0027] The fixed base plate 501 is slidably connected in the corresponding telescopic sleeve hole 403, and the fixed base plate 501 is fixedly connected to the corresponding telescopic cylinder 406. Multiple spray washing plates 503 are all connected to the external spray washing assembly.

[0028] Working principle: During assembly, a material-taking component is set on the side of the device closest to the main control wheel 102, which is the material-taking end, and a material-discharging component is set on the side of the device away from the main control wheel 102, which is the material-discharging end. During operation, the corrugated pipe to be cleaned is placed inside the replacement frame 203. Under the action of the spring, the displacement slider 206 keeps the inner jacking rod 207 tightly against the inner wall of the corrugated pipe, ensuring that the corrugated pipe does not shift or shake during transportation. A start command is issued through the external control component, which sequentially starts the drive component in the fixed control unit 1, the telescopic cylinder 406 of the soaking and cleaning unit 4, and the external spray washing component. The drive component drives the main control wheel 102 to rotate, and the main control wheel 102 drives the drive wheel 103 to rotate through the connecting belt 104, which in turn drives the drive wheel group 1. 05. The drive wheel set 105 and the mating wheel set 106 work together to drive the two conveyor belts 201 to run synchronously and at a uniform speed. As the conveyor unit 2 runs, the replacement frame 203 containing corrugated pipes is placed flat on the two conveyor belts 201 one by one through the unloading end. The connection between the replacement frame 203 and the conveyor belt 201 is kept stable by the constraint block 202 and the docking slot 204. After the outermost replacement frame 203 is placed, the industrial vision size monitor 304 collects the size data of the corrugated pipe inside the replacement frame 203 in real time and transmits it to the external control component. The control component automatically adjusts the conveying speed, spraying pressure and soaking time according to the size data. As the conveyor belt 201 conveys the replacement frame 203 containing corrugated pipes, the industrial vision position monitor 304 collects the size data of the corrugated pipe inside the replacement frame 203 in real time and transmits it to the external control component. The control component automatically adjusts the conveying speed, spraying pressure and soaking time according to the size data. The monitor 302 monitors the position of the replacement frame 203 in real time. When the replacement frame 203 carries the corrugated pipe to the top of the soaking and cleaning section 4, the industrial vision position monitor 302 detects the position status of the corresponding position mating block 303 and sends a trigger signal to the external control component, thereby controlling the conveyor belt 201 to stop. At the same time, the external control component controls the telescopic cylinder 406 to extend, driving the soaking cylinder 404 to move upward along the stabilizing slide 402 and the telescopic sleeve hole 403 until the soaking cylinder 404 is fitted over the replacement frame 203 and the corrugated pipe, and the corrugated pipe is completely immersed in the cleaning solution to soak and clean the impurities on the corrugated pipe. During the first soaking process, the buffer spring 407 plays a buffering role to prevent the soaking cylinder 404 from rising too fast and hitting the corrugated pipe. After the first soaking of the corrugated pipe is completed, the telescopic cylinder 406 retracts, driving the soaking cylinder 404 to reset. Then, the external control component controls the conveyor belt 201 to move continuously and moves the replacement frame 203, which has completed the first soaking and cleaning, to the second soaking and cleaning station. The second soaking and cleaning further cleans the corrugated pipe after the first soaking and cleaning. The multi-stage soaking and cleaning method cleans the corrugated pipe more thoroughly. At the same time, the replacement frame 203 moves synchronously to the first soaking and cleaning position. When the replacement frame 203 carries the corrugated pipe that has completed the second soaking and cleaning to the top of the spray washing section 5, the telescopic cylinder 406 controls the fixed base plate 501 to rise along the telescopic sleeve hole 403, so that the spray washing cylinder 502 is sleeved on the outside of the corrugated pipe and the replacement frame 203.Simultaneously, the external spray washing assembly delivers high-pressure cleaning fluid to the spray washing plates 503. Six circumferentially distributed spray washing plates 503 rotate with the spray washing cylinder 502, performing comprehensive, no-dead-angle spray washing on the surface of the corrugated pipe and its gaps, removing surface impurities. After the spray washing process is completed, as the conveyor belt 201 continues to move, the replacement / disassembly frame 203, having completed the spray washing process, moves towards the material handling end. Then, the external material handling assembly removes the replacement / disassembly frame 203 from the conveyor belt 201.
