Description

Technical Field

[0001] This application relates to the technical field of pipeline inner wall cleaning, and particularly relates to a pipeline inner wall adaptive laser cleaning device. Background Art

[0002] When pipelines are applied in different fields, the requirements for the surface quality and cleanliness of the inner wall of the pipeline are correspondingly different. It is often necessary to deburr or rust-remove the pipeline to improve its surface quality. In recent years, due to the rapid development of laser technology, laser cleaning of the inner wall of pipelines has been widely applied.

[0003] The existing patent publication number CN211438573U discloses a laser cleaning device for the inner wall of a pipeline with automatic focusing, including a pipeline crawling robot, a head optical fiber connection component, an electric zoom component, and a rotary cleaning head component that can rotate 360 degrees along the circumferential direction of the pipeline. One end of the pipeline crawling robot is connected to the laser output end of the head optical fiber connection component, and the other end is connected to the laser input end of the electric zoom component. The laser input end of the head optical fiber connection component is used to connect to a laser generator that generates laser light, and the received laser light is emitted through its laser output end. The laser output end of the electric zoom component is connected to the laser input end of the rotary cleaning head component. There is a first laser transmission channel for the laser beam to pass through in the pipeline crawling robot. The laser beam emitted by the head optical fiber connection component is output to the electric zoom component through the first laser transmission channel in the pipeline crawling robot, and after being zoomed by the electric zoom component, it is output to the rotary cleaning head component and then output to the inner wall of the pipeline through the rotary cleaning head component.

[0004] When the existing laser cleaning device for the inner wall of a pipeline cleans the inside of the pipeline, it cannot collect the impurities generated during cleaning, so that the impurities generated during cleaning still adhere to the inner wall of the pipeline, affecting the adsorption of paint in the later stage. Summary of the Utility Model

[0005] The embodiments of this application provide a pipeline inner wall adaptive laser cleaning device, which can solve the technical problem in the related art that when the laser cleaning device for the inner wall of a pipeline cleans the inside of the pipeline, it cannot collect the impurities generated during cleaning, so that the impurities generated during cleaning still adhere to the inner wall of the pipeline, affecting the adsorption of paint in the later stage.

[0006] The embodiments of this application provide a pipeline inner wall adaptive laser cleaning device, including an optical fiber connection base. One end of the optical fiber connection base is fixedly connected to an optical fiber body, and the other end of the optical fiber connection base is fixedly connected to a driving component. The other end of the driving component is fixedly connected to a cleaning component.

[0007] The driving component includes a driving cavity fixedly connected to the optical fiber connecting seat. At the other end of the driving cavity, there is a conical dust suction port. At one end of the inner cavity of the driving cavity, a plurality of transverse grooves are opened. A filter net is fixedly connected inside the transverse grooves. A moving adsorption assembly is fixedly connected inside the driving cavity. The moving adsorption assembly includes a driving motor fixedly connected to the inside of the driving cavity. At the top of the output end of the driving motor, a dust suction fan blade is fixedly connected. The dust suction fan blade operates to collect the impurities cleaned by the cleaning component.

[0008] By adopting the above technical solution, when the driving motor rotates, it drives the dust suction fan blade to rotate. While rotating, the conical dust suction port adsorbs the impurities cleaned by the cleaning component. The conical dust suction port increases the air pressure of the dust suction fan blade, better adsorbing the cleaned impurities. At the same time, the air pressure containing impurities is discharged from the inside of the driving cavity through the transverse grooves. The filter net collects the impurities into the inside of the driving cavity, reducing the impact on the working environment. At the same time, the air pressure is used to dissipate heat from the driving motor located inside the driving cavity.

[0009] Optionally, a driving gear is fixedly connected to the outer wall of the output end of the driving motor near the edge. A plurality of transmission gears are meshed on the side of the driving gear. The other end of the transmission gear is fixedly connected to a driven column. The top end of the driven column penetrates the driving cavity and is fixedly connected to a worm. A driven gear is meshed on the outer wall of the worm.

[0010] By adopting the above technical solution, when the driving motor operates, the driving gear drives a plurality of transmission gears to rotate. By using the rotation of the transmission gears, the worm can drive the driven gear to rotate.

A plurality of the driven gears are fixedly connected to the outer walls on both sides of the transmission column. A gear belt is rotatably connected in a meshed manner on the outer wall of the driven gear. The other end of the gear belt is internally connected to the same driven gear. Support plates are fixedly connected to both ends of the transmission column. The bottom ends of the support plates are fixedly connected to the outer wall of the driving cavity.

[0012] By adopting the above technical solution, the driven gear can drive a plurality of parallel driven gears under the action of the transmission column. Then, by using the driven gear to drive the gear belt to rotate, the whole device can move forward and backward inside the pipeline. At the same time, the support plates reinforce the driven gear, avoiding the risk of scattering during operation.

[0013] Optionally, a dust-proof cover is attached to the outer wall of the driving motor. The bottom of the dust-proof cover is fixedly connected to the bottom of the driving cavity. A plurality of support bars are fixedly connected inside the conical dust suction port. The other end of the support bar is fixedly connected to a connecting column, and the connecting column is parallel to the driving cavity.

[0014] By adopting the above technical solution, in order to prevent dust from entering the interior of the drive motor, a dust cover is used to protect the drive motor. The dust cover protects the drive motor without affecting its heat dissipation function.

[0015] Optionally, the cleaning component includes a first connecting block fixedly connected to the connecting column, a DC motor fixedly connected to the bottom of the inner cavity of the first connecting block, a transfer connecting disk rotatably connected to the output end of the DC motor, an automatic zoom laser cleaning device fixedly connected to the other end of the transfer connecting disk, and another transfer connecting disk fixedly connected to the other end of the automatic zoom laser cleaning device.

[0016] By adopting the above technical solution, the DC motor drives the automatic zoom laser cleaning device to rotate, cleaning the inside of the pipe in a threaded shape. At the same time, the zoom can be adjusted according to the thickness of the impurities to increase the cleaning intensity.

[0017] Optionally, the other end of the transfer connection disk is rotatably connected to a second connection block, the second connection block is rotatably connected to a rotating column inside, one end of the rotating column is fixedly connected to the transfer connection disk, the other end of the rotating column is fixedly connected to a connecting end, two connecting tubes are fixedly connected on both sides of the connecting end, and a cleaning arm is slidably connected inside the other side of the connecting tube.

[0018] By adopting the above technical solution, while the transfer rotating disk drives the automatic zoom laser cleaning device to clean the inside of the pipe, the transfer rotating disk at the other end of the automatic zoom laser cleaning device drives the rotating column to rotate, so that the connecting end at the other end of the rotating column rotates, and the cleaning arms on both sides of the connecting end clean some plastics that may exist on the inner wall of the pipe to avoid affecting the laser cleaning.

[0019] Optionally, an elastic member is fixedly connected inside the connecting tube, and the other end of the elastic member is fixedly connected to the cleaning arm.

[0020] By adopting the above technical solution, the elastic member can make the cleaning arm shrink, and at the same time can make the cleaning arm always fit the inner wall of the pipe, thereby enhancing the cleaning effect.

[0036] The following will be combined with Figure 1 - Figure 6 to further elaborate on the present invention in detail.

[0037] An adaptive laser cleaning device for the inner wall of a pipeline, comprising an optical fiber connection base 1, one end of the optical fiber connection base 1 is fixedly connected to an optical fiber body 11, the other end of the optical fiber connection base 1 is fixedly connected to a driving component 2, and the other end of the driving component 2 is fixedly connected to a cleaning component 3;

[0038] Refer to Figure 1 and Figure 2 As shown in, the cleaning component 3 includes a first connection block 31. At the bottom of the inner cavity of the first connection block 31, a DC motor 32 is fixedly connected. The output end of the DC motor 32 is rotatably connected to a transfer connection disk 33. The other end of the transfer connection disk 33 is fixedly connected to an auto-focus laser cleaning device 34. The other end of the auto-focus laser cleaning device 34 is fixedly connected to another transfer connection disk 33. The other end of the transfer connection disk 33 is rotatably connected to a second connection block 35. Inside the second connection block 35, a rotating column 30 is rotatably connected. One end of the rotating column 30 is fixedly connected to a transfer connection disk 33. The other end of the rotating column 30 is fixedly connected to a connection end 36. On both sides of the connection end 36, two connection cylinders 37 are fixedly connected. Inside the other side of the connection cylinder 37, a cleaning arm 39 is slidably connected. Inside the connection cylinder 37, an elastic member 38 is fixedly connected. The other end of the elastic member 38 is fixedly connected to the cleaning arm 39.

[0039] With such a setting, when cleaning the inner wall of the pipeline, the cleaning component 3 penetrates into the inner wall of the pipeline, and the driving component 2 is made to fit against the inner wall of the pipeline. The driving component 2 is started to drive the cleaning component 3 to move forward in the pipeline. When cleaning the inner wall of the pipeline, the DC motor 32 drives the transfer rotating disk to rotate. The transfer rotating disk drives the auto-focus laser cleaning device 34 to rotate. The auto-focus laser cleaning device 34 is in a spiral shape to clean the inside of the pipeline, and it can also adjust the zoom according to the thickness of the impurities to increase the cleaning intensity. On the other hand, the transfer rotating disk drives the rotating column 30 to rotate, so that the connection end 36 at the other end of the rotating column 30 rotates. The cleaning arms 39 on both sides of the connection end 36 clean some plastics that may exist on the inner wall of the pipeline to avoid affecting the laser cleaning. At the same time, the elastic member 38 inside the connection cylinder 37 enables the cleaning arm 39 to expand and contract, so that the cleaning arm 39 can always fit against the inner wall of the pipeline, enhancing the cleaning effect on the inner wall of the pipeline.

[0040] Refer to Figure 1 , Figures 3 to 6, the driving component 2 includes a driving cavity 21 fixedly connected to the optical fiber connection base 1. At the other end of the driving cavity 21, there is a conical dust suction port 22. At one end of the inner cavity of the driving cavity 21, there are multiple transverse grooves 27. A filter screen 26 is fixedly connected inside the transverse grooves 27. A moving adsorption assembly 28 is fixedly connected inside the driving cavity 21. The moving adsorption assembly 28 includes a driving motor 280 fixedly connected to the inside of the driving cavity 21. At the top of the output end of the driving motor 280, there is a dust suction fan blade 282. The operation of the dust suction fan blade 282 collects the impurities cleaned by the cleaning component 3.

[0041] When the driving motor 280 rotates, it drives the dust suction fan blade 282 to rotate. While rotating, the conical dust suction port 22 adsorbs the impurities cleaned by the cleaning component 3. The conical dust suction port 22 increases the air pressure of the dust suction fan blade 282 and better adsorbs the cleaned impurities. At the same time, the air pressure containing impurities is discharged from the inside of the driving cavity 21 through the transverse grooves 27. The filter screen 26 collects the impurities inside the driving cavity 21, reducing the impact on the working environment. At the same time, the air pressure is used to dissipate heat from the driving motor 280 located inside the driving cavity 21.

[0042] Refer to Figures 3 to 6 , fixedly connected to the outer wall of the output end of the driving motor 280 near the edge is a driving gear 281. Meshing with the side of the driving gear 281 are multiple transmission gears 283. At the other end of the transmission gear 283, there is a driven column 284. The top of the driven column 284 penetrates the driving cavity 21 and is fixedly connected to a worm 285. Meshing with the outer wall of the worm 285 is a driven gear 286. Inside the driven gear 286, there is a transmission column 288. Fixedly connected to the outer walls on both sides of the transmission column 288 are multiple driven gears 286. Rotationally connected to the outer walls of the driven gears 286 by meshing is a gear belt 287. The other end inside the gear belt 287 is connected to the same driven gear 286. Both ends of the transmission column 288 are fixedly connected to support plates 289. The bottom ends of the support plates 289 are fixedly connected to the outer wall of the driving cavity 21. A dust-proof cover 25 is attached to the outer wall of the driving motor 280. The bottom of the dust-proof cover 25 is fixedly connected to the bottom of the driving cavity 21. Inside the conical dust suction port 22, there are multiple support bars 23 fixedly connected. The other end of the support bar 23 is fixedly connected to a connecting column 24, and the connecting column 24 is parallel to the driving cavity 21.

[0043] Set up like this, when the driving motor 280 operates, it makes the driving gear 281 drive a plurality of transmission gears 283 to rotate. By using the rotation of the transmission gears 283, the worm 285 can drive the driven gear 286 to rotate. Under the action of the transmission column 288, the driven gear 286 can drive a plurality of parallel driven gears 286. Then, by using the driven gear 286, the gear belt 287 can be driven to rotate, enabling the overall device to move forward and backward inside the pipeline. At the same time, the support plate 289 strengthens the driven gear 286 to avoid the risk of scattering during operation. The implementation principle of the pipeline inner wall adaptive laser cleaning device in an embodiment of the present application is as follows: After the cleaning device is lifted into the pipeline, when the driving motor 280 operates, it makes the driving gear 281 drive a plurality of transmission gears 283 to rotate. By using the rotation of the transmission gears 283, the worm 285 can drive the driven gear 286 to rotate. Under the action of the transmission column 288, the driven gear 286 can drive a plurality of parallel driven gears 286. Then, by using the driven gear 286, the gear belt 287 can be driven to rotate, enabling the overall device to move forward and backward inside the pipeline. At the same time, the driving motor 280 drives the dust suction fan blade 282 to rotate. While rotating, the impurities cleaned by the cleaning component 3 are adsorbed by the conical dust suction port 22. The conical dust suction port 22 increases the air pressure of the dust suction fan blade 282. The air pressure containing impurities is discharged from the inside of the driving cavity 21 through the transverse groove 27. The filter screen 26 collects the impurities into the inside of the driving cavity 21 to reduce the impact on the working environment. Finally, the automatic zoom laser device is driven by the DC motor 32 to clean the pipe wall spirally, and the rotating transfer disk drives the elastic cleaning arm 39 to scrape off the plastic residues to ensure the cleaning effect.
