Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of CIPP pipeline detection, in particular to a CIPP pipeline repair accurate positioning detection device. BACKGROUND

[0002] CIPP is the current international mainstream trenchless pipeline repair technology, the core of which is to realize the structural repair and functional regeneration of damaged pipelines by curing a layer of high-strength lining pipe in the original pipeline, and it is widely used in municipal rainwater and sewage pipes, water supply pipes, industrial pipelines and other scenes, and is especially suitable for pipeline repair projects that cannot be excavated (such as crossing roads, buildings, rivers) or have high excavation costs.

[0003] The CIPP pipeline repair positioning detection process includes three stages: before repair, during repair and after repair. Before repair, high-pressure water guns are used for dredging, air bags are used for water blocking, and the cleanliness of the pipeline is improved. Then, a detection robot or a sonar device is used to enter the pipeline to collect video and mileage data in real time, locate the coordinates of defects such as cracks and corrosion. During repair, for pull-in or inversion CIPP process, a laser positioning instrument is used to monitor the offset of the lining pipe, a pressure sensor is used to feedback the jamming situation, and UV curing is used to record the light intensity and temperature simultaneously. For hot water / steam curing, the water temperature and pressure are controlled to ensure that the lining pipe is wrinkle-free and uniformly cured. After repair, a detection robot is used to recheck the integrity of the lining pipe 24 hours later, and a closed water or air pressure test is carried out to verify the sealing performance.

[0026] In summary, the present invention has the following main beneficial effects: This invention solves the problem of residual water inside the pipeline affecting the detection data of internal pipeline loss by setting a first air outlet plate and a second air outlet plate. After the high-pressure water gun cleans the inside of the pipeline, the main body of the device enters the pipeline. Then, the air pump is started, and the air is conducted to the first air outlet pipe. The air flows to the first air outlet and the second air outlet. The first connecting pipe conducts part of the air flow to the inside of the first air supply pipe. Then, the air flow is transmitted to the inside of the first air outlet plate through the first air supply pipe. The first air outlet plate discharges the air flow. The second connecting pipe conducts part of the air flow to the inside of the second air supply pipe. Then, the air flow is transmitted to the inside of the second air outlet plate through the second air supply pipe. The second air outlet plate discharges the air flow. The first air outlet plate and the second air outlet plate work together to blow away the water in front of the main body of the device, so that the water flows to the front end, exposing the pipeline area covered by the water, thus avoiding the impact of water accumulation on the detection data.

[0027] This invention comprises a first air outlet pipe, a first air cushion, and a second air outlet pipe. A first solenoid valve is closed, and a second solenoid valve is open, allowing airflow to flow towards the second solenoid valve. The airflow enters the first branch pipe and then passes through the first branch pipe into two sets of third connecting pipes. A portion of the airflow enters two sets of air inlets, which in turn enter the two sets of second air cushions. The two sets of second air cushions expand, and their outer walls adhere to the inner walls of the pipes, thus sealing the pipes in the area where the main body of the device is located. A pressure-measuring air pump is activated, allowing airflow to enter between the two sets of mounting plates through the second air inlet pipe. Airflow is continuously input, and once the space between the two sets of mounting plates is filled, the pressure-measuring air pump measures the air pressure between the two sets of mounting plates. If the air pressure does not change within a certain time, no leaks are detected in the sealed section of the pipe.

[0028] This invention incorporates limiting rings, mounting columns, and a scanning device. The rotation of the two sets of limiting rings causes the mounting columns to rotate around a mounting plate, which in turn drives the scanning device. The scanning device activates during rotation and scans the inner wall of the pipe, transmitting the scanned data to a data receiving platform. If the inner wall of the pipe is damaged, the data receiving platform marks and locates the damaged area. This avoids the need for workers to spend extended periods observing video data captured inside the pipe to determine the damaged area, reducing the workload of workers, improving the accuracy of pipe inner wall damage data, and preventing misjudgments caused by visual fatigue from prolonged video viewing.

[0043] The working principle of this invention is as follows: When the operator uses this device to inspect the damaged area inside the pipe, after the high-pressure water gun cleans the inside of the pipe, the operator places the main body 1 of the device inside the pipe. Then, the air pump is started, and the airflow is conducted to the first air outlet 25. The first solenoid valve 26 is in the open state, and the second solenoid valve 36 and the third solenoid valve 44 are in the closed state. The airflow flows to the first air outlet 27 and the second air outlet 28. The first air outlet 27 and the second air outlet 28 are respectively connected to the first connecting pipe 29 and the second connecting pipe 32. Next, the first connecting pipe 29 conducts part of the airflow into the first air supply pipe 30, and then the airflow is transmitted through the first air supply pipe 30 to the first air outlet plate 31. The first air outlet plate 31 discharges the airflow. The second connecting pipe 32 conducts part of the airflow into the second air supply pipe 33, and then the airflow is transmitted through the second air supply pipe 33 to the second air outlet plate 34. The second air outlet plate 34 discharges the airflow. The first air outlet plate 31 and the second air outlet plate 34 work together to blow the water in front of the main body 1 of the device, so that the water flows to the front end. When the accumulated water flows forward, the drive mechanism 2 is activated, driving a set of drive shafts 3 to rotate. The two sets of drive shafts 3 are connected by a toothed synchronous belt, so the two sets of drive shafts 3 rotate synchronously, thereby driving multiple sets of rollers 4 to rotate, thereby driving the main body of the device 1 and the two sets of mounting plates 15 to move. When the main body 1 of the device moves a certain distance, the drive mechanism 2 is closed, the main body 1 of the device stops moving, the first solenoid valve 26 is closed, the second solenoid valve 36 is opened, the airflow flows towards the second solenoid valve 36, the airflow enters the interior of the first branch pipe 35, and then the airflow enters the interior of the two sets of third connecting pipes 37 through the first branch pipe 35. When the airflow enters the two sets of third connecting pipes 37, part of the airflow enters the two sets of second branch pipes 38 through the two sets of third connecting pipes 37. The two sets of second branch pipes 38 respectively input the airflow into the two sets of first air cushions 39. After the two sets of first air cushions 39 are inflated, they expand and push one end of the two sets of mounting brackets 8 to move inside the two sets of slides 16, so that one end of the two sets of mounting brackets 8 moves to the upper end of the two sets of slides 16. At the same time, one end of the two sets of first limiting gears 18 enters the two sets of reserved slots 9, so that the two sets of first limiting gears 18 respectively mesh with the two sets of movable gears 14. When the airflow enters the two sets of third connecting pipes 37, part of the airflow enters the two sets of air inlets 41 respectively. The airflow enters the two sets of second air cushions 40 from the two sets of air inlets 41. The two sets of second air cushions 40 expand. After the two sets of second air cushions 40 expand, the outer walls of the two sets of second air cushions 40 are attached to the inner wall of the pipe, thereby sealing the pipe in the area where the main body of the device 1 is located. When the pipeline is partially sealed, the pressure measuring air pump is started, so that the airflow enters the space between the two sets of mounting plates 15 through the second air inlet pipe 42. The airflow continues to be input. After the airflow fills the space between the two sets of mounting plates 15, the pressure measuring air pump measures the air pressure between the two sets of mounting plates 15. If the air pressure does not change within a certain period of time, there is no leak in the sealed section of the pipeline. When the pipeline is partially sealed and the two sets of mounting brackets 8 drive the main body 1 of the device to be in a suspended state, the drive mechanism 2 is started, driving the two sets of drive shafts 3 to rotate, thereby driving the drive bevel gear 5 to rotate. The drive bevel gear 5 meshes with the transmission bevel gear 7, so the transmission bevel gear 7 rotates, driving the transmission shaft 6 to rotate. The transmission shaft 6 is connected to the two sets of connecting shafts 10 through toothed synchronous belts. The two sets of connecting shafts 10 rotate, driving the two sets of connecting bevel gears 11 to rotate. The two sets of connecting bevel gears 11 mesh with the two sets of movable bevel gears 13 respectively. The two sets of movable bevel gears 13 rotate, thereby driving the two sets of movable shafts 12 to rotate, and then driving the two sets of movable gears 14 to rotate. When the two sets of movable gears 14 rotate, they mesh with the two sets of first limiting gears 18. The rotation of the first limiting gears 18 drives the rotation of the two sets of first limiting shafts 17. The two sets of first limiting shafts 17 are connected to the two sets of second limiting shafts 19 via toothed synchronous belts. Therefore, the rotation of the two sets of second limiting shafts 19 drives the rotation of the two sets of second limiting gears 20. The two sets of second limiting gears 20 mesh with the two sets of gear rings 22. The rotation of the gear rings 22 drives the rotation of the two sets of limiting rings 21, thereby… The mounting column 23 rotates around the mounting plate 15, which in turn drives the scanning device 24 to rotate. The scanning device 24 starts rotating and scans the inner wall of the pipe, transmitting the scan data to the data receiving platform. If the inner wall of the pipe is damaged, the data receiving platform will mark and locate the area where it is located. This avoids the need for staff to observe the video data captured inside the pipe for a long time to judge the damaged area inside the pipe, reduces the workload of staff, improves the accuracy of the data on damage to the inner wall of the pipe, and avoids misjudgment caused by visual fatigue caused by staff watching videos for a long time.
