Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Example 1:

[0028] like Figures 1 to 6 As shown, an endoscope for pipe repair includes a storage cylinder 1 with endoscope structures at both ends of the storage cylinder 1.

[0029] The endoscopic structure includes a detection mechanism 3 and an auxiliary mechanism 4;

[0030] The detection mechanism 3 includes a dividing plate 301, a pump 302, a guide pipe 303, a drive motor 304, and a rotating rod 305. The outer side of the dividing plate 301 is connected to the inner wall of the storage cylinder 1. One end of the pump 302 is connected to one end of the guide pipe 303. The output end of the drive motor 304 is connected to one end of the rotating rod 305. A connecting plate 306 is fixedly installed on the other end of the rotating rod 305. A rotating rod 307 is fixedly installed on one side of the connecting plate 306. A rotating plate 308 is slidably connected to one end of the rotating rod 307. An electric telescopic rod 309 is fixedly installed on one side of the connecting plate 306. An installation plate 310 is fixedly installed on one end of the electric telescopic rod 309. A nozzle 311 is fixedly installed on one side of the installation plate 310. A scraper 312 is fixedly installed on one side of the installation plate 310. A detection probe 313 is fixedly installed on the outer wall of the storage cylinder 1.

[0031] In this embodiment, there are two dividing plates 301, which are symmetrically distributed on the inner wall of the storage cylinder 1. There are also two guide pipes 303, which are symmetrically distributed on both sides of the extraction pump 302. This allows the cleaning liquid to be sprayed onto the inner wall of the pipe quickly and conveniently, thus enabling better cleaning and testing.

[0032] Furthermore, there are six rotating rods 307, which are symmetrically distributed on one side of the connecting plate 306. A rotating groove is provided on one side of the rotating plate 308. One end of the rotating rod 307 is slidably connected to the inner wall of the rotating groove, so that the nozzle 311 and scraper 312 can be rotated quickly and conveniently, thereby enabling better detection work.

[0033] Furthermore, there are several electric telescopic rods 309, which are symmetrically distributed on the outside of the connecting plate 306. There are also several nozzles 311, which are symmetrically distributed on the outside of the connecting plate 306. This allows for quick and convenient adjustment of the positions of the nozzles 311 and the scraper 312, thereby enabling better cleaning.

[0034] The testing agency quantifies the operating procedures (taking "a municipal sewage pipe with silt residue on the inner wall in a diameter of 800mm" as an example).

[0035] Cleaning operation

[0036] Parameter settings:

[0037] The electric telescopic rod extends 200mm (8mm distance between the nozzle / scraper and the inner wall of the pipe), the pump pressure is set to 0.5MPa, the flow rate is 10L / min, the drive motor speed is 40r / min, and the equipment moving speed is 0.3m / min;

[0038] Spraying and scraping linkage:

[0039] Start the extraction pump, and the cleaning fluid is delivered to the nozzle through the guide pipe. The fan-shaped spray covers the inner wall of the pipe (spray angle 60°, overlap rate of adjacent nozzles 30%). The scraper rotates with the drive motor to scrape away the mud and sand (scraping pressure 0.2MPa).

[0040] Cleaning effect verification:

[0041] After cleaning, observation using a detection probe revealed no visible mud or sand on the inner wall of the pipe (residual amount ≤0.1g / m³). 2 If no cleaning solution residue or foam remains, the cleaning is considered successful. If residue still remains, increase the pump pressure to 0.7 MPa and repeat the cleaning process once.

[0042] Detection operation

[0043] Probe calibration:

[0044] Start the detection probe, calibrate the resolution (1080P) and frame rate (30fps) to ensure that the image is distortion-free (distortion rate ≤1%);

[0045] Motion detection:

[0046] The equipment moves at a speed of 0.2 m / min, and the detection probe takes real-time pictures of the inner wall of the pipe, focusing on recording areas of damage, corrosion, and residual impurities (no defects ≥0.5 mm are missed);

[0047] Data storage:

[0048] The detection data is automatically stored (MP4 format), and a detection node is marked every 5m to facilitate subsequent positioning and repair.

[0049] When it is necessary to observe and inspect the inside of the pipeline, the operator places the storage cylinder 1 inside the pipeline. At this time, by activating the auxiliary mechanism 4, the casters 411 can be brought into contact with the inner wall of the pipeline, and the device can be moved by the casters 411. At this time, by activating the extraction pump 302, the cleaning fluid stored in the storage cylinder 1 can be transported to the nozzle 311 through the guide pipe 303, and sprayed onto the inner wall of the pipeline by the nozzle 311, thereby cleaning the impurities on the inner wall of the pipeline. As the device moves, the scraper 312 installed on one side of the mounting plate 310 can scrape off the remaining impurities on the inner wall of the pipeline, thereby enabling more accurate inspection. At this time, by activating the drive motor 304, the rotating rod 305 is driven to rotate, and the rotating rod 305 drives the connecting plate 306 to rotate. The rotation of the connecting plate 306 causes the rotating rod 307 to slide inside the rotating plate 308, thereby increasing the stability of the connecting plate 306 during rotation. The rotation of the connecting plate 306 indirectly drives the nozzle 311 and scraper 312 to rotate, thus enabling better cleaning. When it is necessary to inspect pipes of different sizes, the electric telescopic rod 309 is activated to move the mounting plate 310. The movement of the mounting plate 310 drives the nozzle 311 and scraper 312 to move, thus enabling quick and convenient adjustment of the position of the nozzle 311 and scraper 312. This allows for better cleaning of the inner walls of pipes of different sizes and better inspection. After cleaning is completed, the detection probe 313 is activated to inspect the inner walls of the pipe, thus enabling better use.

[0050] Example 2:

[0051] Based on Embodiment 1, the auxiliary mechanism 4 includes a fixed ring 401, a movable plate 402, a movable rod 403, a swing plate 404, and a bearing plate 405. One side of the fixed ring 401 is connected to one side of the movable plate 402. The inner side of the movable plate 402 is rotatably connected to one end of the movable rod 403. The outer wall of the movable rod 403 is connected to the inner wall of the swing plate 404. One end of the movable rod 403 is connected to one side of the bearing plate 405. A threaded rod 406 is threadedly connected to the inner wall of the bearing plate 405. An adjustment box 407 is fixedly installed at one end of the swing plate 404. An electric telescopic rod 408 is fixedly installed on the inner wall of the adjustment box 407. An adjustment plate 409 is fixedly installed at one end of the electric telescopic rod 408. A support rod 410 is fixedly installed on one side of the adjustment plate 409. A caster wheel 411 is fixedly installed at one end of the support rod 410.

[0052] In this embodiment, there are two fixing rings 401, which are symmetrically distributed on the outside of the storage cylinder 1. A limit hole is opened on one side of the movable plate 402. One end of the threaded rod 406 is threadedly connected to the inner wall of the limit hole. There are six casters 411, which are symmetrically distributed on the outside of the two fixing rings 401, so that the angle and position of the casters 411 can be quickly and conveniently adjusted, and thus can move on the inner wall of pipes of different sizes.

[0053] Furthermore, the inner wall of the storage cylinder 1 is connected to one end of the extraction pump 302, one end of the storage cylinder 1 is connected to one end of the drive motor 304, and the outer wall of the storage cylinder 1 is connected to the inner wall of the fixing ring 401.

[0054] Quantitative operating procedures for auxiliary mechanisms (for pipes with a diameter of 800mm as described above)

[0055] Adjusting the angle and position of the casters

[0056] Angle unlock:

[0057] Loosen the threaded rod (torque drops from 15 N·m to 0), release the locking of the movable rod, and manually rotate the movable rod to 30° (to adapt to an 800 mm pipe curvature);

[0058] Position adjustment:

[0059] Start the second electric telescopic rod, set it to extend 120mm, and drive the casters to move towards the inner wall of the pipe until the casters are fully in contact (contact pressure 0.1MPa);

[0060] Locking and fixing:

[0061] Tighten the threaded rod to 15 N·m, gently push the equipment (apply force ≤ 20 N), and if there is no displacement, it is considered properly fixed. The six casters are symmetrically distributed (with an included angle of 60°) to ensure smooth movement.

[0062] When it is necessary to observe and inspect the inside of the pipeline, the operator places the storage cylinder 1 inside the pipeline. At this time, the threaded rod 406 is rotated to move it on the inner wall of the support plate 405. The movement of the threaded rod 406 allows it to be pulled out from one side of the movable plate 402, thereby removing the limiting fixation on the support plate 405. Rotating the support plate 405 then drives the movable rod 403 to rotate, which in turn drives the swing plate 404 to rotate. The rotation of the swing plate 404 indirectly drives the universal wheel 411 to rotate, thus allowing for quick and convenient adjustment of the angle between the universal wheel 411 and the storage cylinder 1. At this time, by activating the electric telescopic rod 408, the adjusting plate 409 slides on the inner wall of the adjusting box 407. The sliding of the adjusting plate 409 drives the support rod 410 to move, which in turn drives the universal wheel 411 to move, thus allowing for quick and convenient adjustment of the position of the universal wheel 411. This allows for adjustment according to different sizes of pipelines, enabling it to move on the inner wall of pipelines of different sizes. Activating the detection mechanism 3 allows for quick and convenient inspection of the inside of the pipeline.
