Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a crawling detection device for municipal drainage pipeline inspection. Background Technology

[0002] Pipeline inspection refers to the operation of using the pipeline medium to drive a detector inside the pipeline to detect and record damage such as deformation and corrosion in real time, and to accurately locate the damage. Most oil and gas pipelines are buried underground. Through pipeline inspection, various defects and damages can be detected in advance, the degree of danger of each pipeline section can be understood, accidents can be prevented and effectively reduced, and pipeline maintenance funds can be saved. It is an important measure to ensure pipeline safety.

[0003] Existing detection devices are typically crawlers, placed inside pipes to move along their length, allowing pipe television inspection devices to inspect the pipes. However, during inspection, due to differences in pipe dimensions, the inspection vehicle is prone to tipping over. Furthermore, during the crawling inspection process inside the pipe, a large amount of dirt accumulates inside due to prolonged use, affecting the normal operation of the detection device. In addition, the device has poor flexibility, limited monitoring range, and affects the detection effect.

[0004] Based on this, a crawling detection device for municipal drainage pipe inspection is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] In one embodiment, such as Figures 1-5As shown, a crawling detection device for municipal drainage pipeline inspection includes a housing 1, a protective cover 2 at the top of the housing 1, a monitoring camera 17 above the protective cover 2, drive mechanisms at both ends of the housing 1, a rotating column 3 inside the housing 1, the bottom end of the rotating column 3 being rotatably connected to the bottom surface of the housing 1, a turntable 4 inside the protective cover 2 penetrating the top of the rotating column 3, a rotating mechanism on one side of the rotating column 3, a lifting mechanism between the turntable 4 and the monitoring camera 17, and an adjustment mechanism at the bottom of one side of the monitoring camera 17. The drive mechanism can move the housing 1 inside the pipeline and avoid dirt and debris. The monitoring camera 17 can monitor the internal environment of the pipeline. The rotating mechanism can drive the rotating column 3 to rotate, which in turn drives the turntable 4 to rotate, thereby adjusting the horizontal angle of the monitoring camera 17. The adjustment mechanism can adjust the vertical angle of the monitoring camera 17, and the lifting mechanism can adjust the height of the monitoring camera 17.

[0025] In one embodiment, such as Figure 2 As shown, the rotating mechanism includes a gear ring 5, which is located on the rotating column 3 inside the housing 1. A first motor 6 is installed inside the housing 1 on one side of the rotating column 3. A first rotating shaft 7 is installed at the output end of the first motor 6. A gear 8 is installed at the top of the first rotating shaft 7. The gear 8 meshes with the gear ring 5. The first motor 6 can drive the gear 8 to rotate. Through the meshing of the gear 8 and the gear ring 5, the gear ring 5 is driven to rotate, so that the rotating column 3 and the turntable 4 rotate synchronously.

[0026] In one embodiment, such as Figure 3 As shown, a circular groove 9 is provided on the top surface of the box 1 outside the rotating column 3. Several sliders 10 are provided in the circular groove 9. The sliders 10 are slidably connected in the circular groove 9. A first connecting rod 11 is provided on the slider 10 and fixedly connected to the turntable 4, so that the turntable 4 rotates more stably.

[0027] In one embodiment, such as Figure 2 As shown, the lifting mechanism includes an air pump 12, which is located on the turntable 4. A telescopic column 13 is provided at the output end of the air pump 12. A connector 14 is provided at the top of the telescopic column 13 through the top surface of the protective cover 2. A rotating plate 15 is provided at the bottom of the monitoring camera 17. The rotating plate 15 and the connector 14 are rotatably connected by a connecting shaft 16. The air pump 12 can drive the rotating plate 15 on the telescopic column 13 to lift and lower, thereby driving the monitoring camera 17 to adjust its height.

[0028] In one embodiment, such as Figure 3As shown, a fixed plate 18 is provided on the telescopic column 13 above the protective cover 2. A symmetrical first support plate 19 is provided on the fixed plate 18 on one side of the telescopic column 13. A first rotating shaft 20 is provided between the first support plates 19. During the rotation of the turntable 4, the air pump 12 rotates together, so that the fixed plate 18 on the telescopic column 13 rotates synchronously.

[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the adjustment mechanism includes a first sleeve 21, which is rotatably connected to a first rotating shaft 20. A first electric push rod 22 is provided on the first sleeve 21. A movable groove 26 is provided on one bottom surface of the rotating plate 15. A second support plate 23 is slidably connected in the movable groove 26. A second sleeve 25 is rotatably connected to a second rotating shaft 24 between the second support plates 23. The output end of the first electric push rod 22 is fixedly connected to the second sleeve 25. The first electric push rod 22 can push the rotating plate 15 to rotate around the connecting shaft 16 to adjust the longitudinal angle of the monitoring camera 17.

[0030] In one embodiment, such as Figure 2 As shown, the drive mechanism includes a second motor 27, which is located on both sides of the inner wall of the housing 1. A second rotating shaft 28 is provided at the output end of the second motor 27, and a bearing block 29 is provided at the outer end of the second rotating shaft 28. Several second electric push rods 30 are provided on the bearing block 29, and electric rollers 31 are provided at the output end of the second electric push rods 30. The second electric push rods 30 can drive the electric rollers 31 to contact the inner wall of the pipe, thereby improving stability. The electric rollers 31 can drive the device to move inside the pipe. When the rollers encounter dirt or debris, the second motor 27 is activated to drive the bearing block 29 to rotate, thereby rotating the position of the electric rollers 31 and preventing the electric rollers 31 from being restricted in their movement.

[0031] The above embodiments disclose a crawling detection device for municipal drainage pipeline inspection. In use, activating the second electric push rod 30 drives the electric roller 31 to contact the inner wall of the pipeline, improving stability. The electric roller 31 moves the device within the pipeline. When the roller encounters dirt or debris, activating the second motor 27 drives the bearing block 29 to rotate, thereby rotating the position of the electric roller 31 and preventing its movement from being restricted. Activating the air pump 12 causes the rotating plate 15 on the telescopic column 13 to rise and fall, thereby driving the monitoring camera 17 to perform high-speed inspection. The angle is adjusted by starting the first motor 6, which drives the gear 8 to rotate. The gear 8 meshes with the gear ring 5, thereby driving the gear ring 5 to rotate, so that the rotating column 3 and the turntable 4 rotate synchronously. During the rotation of the turntable 4, the air pump 12 rotates together, thereby adjusting the horizontal angle of the monitoring camera 17 to monitor the area around the pipeline and improve flexibility. The first electric push rod 22 is then activated, which pushes the rotating plate 15 to rotate around the connecting shaft 16, thereby adjusting the vertical angle of the monitoring camera 17 and increasing the monitoring range.
