Description

Technical Field

[0001] This utility model relates to the field of pipeline inner wall detection technology, specifically to an intelligent detection device for corrosion of the inner wall of pressure pipelines. Background Technology

[0002] A pipeline is a tubular device that uses pressure to transport gases or liquids. If the inner wall of the pipeline leaks due to corrosion, it can cause serious safety accidents. Regular corrosion testing can detect corrosion on the pipeline's inner wall in a timely manner, allowing for appropriate repair or replacement measures to prevent accidents and ensure the safe operation of the pipeline.

[0003] While current ultrasonic testing devices possess good detection capabilities, their level of intelligence is relatively low. After prolonged use, tubular equipment that transports liquids will accumulate a layer of scale on its inner wall. The acoustic characteristics of scale differ from those of the pipe material, causing ultrasonic waves to be reflected, refracted, and scattered at the interface between the two. Some energy cannot propagate smoothly to the inner wall and interior of the pipe, thus weakening the detected signal intensity and affecting the accurate assessment of pipe corrosion. Current ultrasonic testing devices cannot adjust the testing operation according to the type of medium being transported in the pipeline. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-8 This utility model provides an intelligent detection device for corrosion of the inner wall of a pressure pipeline, comprising: a frame 1, and further comprising: a helical tube 2 rotatably mounted on one side of the outer wall of the frame 1, a slider 3 screwed onto the helical tube 2, and multiple equally spaced moving components 4 rotatably mounted on the outer wall of the slider 3, one of the moving components 4 being mounted with a first motor 5, and a long shaft 6 rotatably mounted on the other side of the outer wall of the frame 1, an ultrasonic detection head 7 being mounted on one end of the long shaft 6, a scraping component 9 being mounted on the other end of the long shaft 6, a conductive slip ring 8 being mounted on the outer wall of the long shaft 6, a control drive component 10 being mounted on one end of the bottom outer wall of the frame 1, a driven gear 11 being mounted on the outside of the long shaft 6, and a camera 12 being mounted on the frame 1.

[0024] It should be noted that: the frame 1 can be placed inside the pressure pipe, and the solenoid 2 can be rotated to move the four moving components outwards from the frame 1, supporting them on the inner wall of the pressure pipe, so that the frame 1 is located on the centerline of the pipe. At this time, the first motor 5 can drive one of the moving components 4 to move, thereby moving the device inside the pressure pipe. The control drive component 10 can drive the long shaft 6 to rotate, thereby driving the ultrasonic detection head 7 to rotate, performing ultrasonic corrosion detection on the inner wall of the pressure pipe. The camera 12 can observe the condition of the inner wall of the pressure pipe and transmit the image to the control drive component 10 for analysis. When there is scale on the inner wall of the pressure pipe, the control drive component 10 can control the scraping component 9 to change from a horizontal state to a vertical state. The scraping component 9 rotates with the long shaft 6 to scrape the scale on the inner wall of the pressure pipe, removing the scale, improving the accuracy of ultrasonic detection, and making it more intelligent.

[0025] In a preferred embodiment, the moving component 4 includes a support plate 401, connecting plates 402 rotatably mounted on both ends of the bottom outer wall of the support plate 401, and moving wheels 403 mounted on both ends of the top of the support plate 401.

[0026] It should be noted here that: when the screw tube 2 is rotated, the slider 3 can drive the connecting plate 402 at one end of the bottom of the support plate 401 to move, so that the support plate 401 is lifted up and the moving wheel 403 is pressed against the inner wall of the pressure pipe.

[0027] In a preferred embodiment, the scraping assembly 9 includes a mounting frame 901, a rotating roller 902 rotatably mounted on the inner wall of the mounting frame 901, a spring rod 904 mounted on one side of the outer wall of the rotating roller 902, a scraper 905 mounted on one end of the spring rod 904, and an electric rotary table 903 mounted on one side of the outer wall of the mounting frame 901, wherein the rotating part of the electric rotary table 903 is connected to the rotating roller 902.

[0028] It should be noted that the electric rotary table 903 can drive the roller 902 to rotate 90°, which in turn drives the elastic rod 904 and scraper 905 to rotate, so that the elastic rod 904 stands up and uses the elastic rod 904 to push the scraper 905 against the inner wall of the pressure pipe.

[0029] In a preferred embodiment, the elastic rod 904 includes a tube 904-1, a movable rod 904-2 slidably connected to the inner wall of the tube 904-1, and a spring 904-3 disposed inside the tube 904-1.

[0030] It should be noted that during the rotation of the elastic rod 904, the scraper 905 is brought into contact with the inner wall of the pressure pipe. The scraper 905 drives the movable rod 904-2 to move into the pipe body 904-1, compressing the spring 904-3. The reaction force of the spring 904-3 is used to push the scraper 905 against the inner wall of the pressure pipe.

[0031] In a preferred embodiment, the control drive assembly 10 includes a mounting plate 1001, a controller 1002 mounted on one side of the outer wall of the mounting plate 1001, a second motor 1003 mounted on the other side of the outer wall of the mounting plate 1001, and a gear 1004 mounted on the output shaft of the second motor 1003.

[0032] It should be noted that: the controller 1002 can control the electronic equipment in the device, and the second motor 1003 can drive the gear 1004 to rotate, which in turn drives the driven gear 11 to rotate, which in turn drives the long shaft 6 to rotate.

[0033] In a preferred embodiment, one bottom end of one connecting plate 402 is rotatably connected to the outer wall of the slider 3, and one bottom end of the other connecting plate 402 is rotatably connected to the outer wall of the frame 1.

[0034] It should be noted that the movement of slider 3 can cause one end of the bottom of one of the connecting plates 402 to move.

[0035] Working principle: The frame 1 can be placed inside the pressure pipe. Rotating the screw tube 2 and the slider 3 can drive the connecting plate 402 at the bottom of the support plate 401 to move, supporting the support plate 401 and making the moving wheel 403 press against the inner wall of the pressure pipe, so that the frame 1 is located on the center line of the pipe. At this time, the first motor 5 can drive one of the moving wheels 403 to rotate, thereby driving the device to move inside the pressure pipe.

[0036] The second motor 1003 drives the gear 1004 to rotate, which in turn drives the driven gear 11 to rotate, which in turn drives the long shaft 6 to rotate, which in turn drives the ultrasonic detection head 7 to rotate, performing ultrasonic corrosion detection on the inner wall of the pressure pipeline. The camera 12 can observe the condition of the inner wall of the pressure pipeline and transmit the image to the controller 1002 for analysis. When there is scale on the inner wall of the pressure pipeline, the controller 1002 controls the electric rotary table 903 to drive the roller 902 to rotate 90°, which in turn drives the elastic rod 904 and scraper 905 to rotate, so that the elastic rod 904 stands up and uses the elastic rod 904 to push the scraper 905 against the inner wall of the pressure pipeline. The scraper 905, along with the rotation of the long shaft 6, scrapes the scale on the inner wall of the pressure pipeline, removing the scale, improving the accuracy of ultrasonic detection, and making it more intelligent.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
