Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , the utility model provides a technical solution:

[0024] The water conservancy project pipeline leakage detection assembly includes a base 1. A front riser 111 and a rear riser 13 are fixedly mounted near the top and ends of the base 1, respectively. A movable riser 112 is slidably mounted between the front riser 111 and the rear riser 13. A turntable 14 is rotatably mounted on the outer walls of each of the front and movable risers 111, 112, on opposite sides of the two. A first pressure sensor 140 is fixedly mounted at the center of one of the turntables 14. A fan 3 is fixedly mounted on the top of the base 1. The air outlet of the fan 3 is connected to the center of the other turntable 14 via an air pipe 30. A solenoid valve 31 is mounted on the air pipe 30. The air pipe 30 is rotatably connected to the turntable 14 via a sealed bearing. A drive motor 110 is mounted on the movable riser 112, whose output shaft is coaxially fixed to the turntable 14. The turntables 14 on the front and movable risers 111, 112, and the first pressure sensor 140 enable accurate detection of the internal pressure of the pipeline, thereby determining whether the pipeline is leaking. At the same time, the fan 3 and the air pipe 30 can be used to blow air or generate negative pressure into the pipeline, further enhancing the effect of leakage detection. The design of the movable vertical plate 112 enables the detection component to adapt to pipelines of different lengths, improving the flexibility and applicability of the detection.

[0025] As a preferred embodiment of this embodiment, two first screw rods 11 are symmetrically mounted between the front riser 111 and the rear riser 13 for rotation. Both first screw rods 11 are threadedly connected to the movable riser 112. Furthermore, two first adjustment motors 12 are fixedly mounted on the rear riser 13, each having an output shaft coaxially fixed to the two first screw rods 11. The design of the first screw rods 11 and the first adjustment motor 12 allows for precise control of the position of the movable riser 112 between the front riser 111 and the rear riser 13, thereby accommodating pipes of varying lengths and improving detection accuracy and flexibility.

[0026] As a preferred embodiment of this embodiment, a second screw rod 17 is rotatably mounted near the top of the movable riser 112. This second screw rod 17 passes through the front riser 111. A connecting bearing 19 is installed between the second screw rod 17 and the front riser 111. The second screw rod 17 is slidably connected to the inner front shaft of the connecting bearing 19. A movable frame 15 is threadedly connected to the second screw rod 17. Two guide rods 16 are symmetrically fixedly mounted near the top of the front riser 111. The guide rods 16 pass through the movable frame 15 and the movable riser 112. A second adjustment motor 18, whose output shaft is coaxially fixed to the second screw rod 17, is fixedly mounted on the movable riser 112. A mounting plate 151 is located below the movable frame 15. A second pressure sensor 152 is fixed to the bottom of the mounting plate 151. Two first hydraulic cylinders 150 are symmetrically fixedly mounted at the bottom of the movable frame 15. The top of the mounting plate 151 is fixedly connected to the piston rods of both first hydraulic cylinders 150. The design of first hydraulic cylinder 150 and mounting plate 151 allows for precise control of second pressure sensor 152, enabling it to closely adhere to the inner wall of the pipe for detection. The addition of second pressure sensor 152 further enhances leak detection capabilities, improves detection accuracy, and allows precise location of leaks.

[0027] As a preferred embodiment of this invention, a movable support 2 is slidably mounted on the top of the base 1. The movable support 2 includes a bottom plate 20 slidably mounted on the base 1. A mounting frame 23 that can move up and down is provided above the bottom plate 20. Two rollers 24 are symmetrically mounted in the mounting frame 23. The movable support 2 is designed to support the bottom of the pipeline to be inspected to reduce its pressure on the turntable 14.

[0028] As a preferred feature of this embodiment, two second hydraulic cylinders 22 are symmetrically fixedly connected to the top of the base plate 20, and the mounting bracket 23 is fixedly connected to the piston rods of both second hydraulic cylinders 22. The design of the second hydraulic cylinders 22 allows the mounting bracket 23 to move up and down, thereby accommodating pipes of varying diameters. This design further enhances the applicability and flexibility of the detection assembly.

[0029] As a preferred feature of this embodiment, the top of the base 1 is provided with a chute 10 that is slidably connected to the bottom plate 20. A limiting groove 101 is provided on either side of the chute 10. A limiting plate 21 is integrally formed on each side of the bottom plate 20, and the two limiting plates 21 are slidably connected to the two limiting grooves 101, respectively. The design of the chute 10 and limiting grooves 101 ensures the stability and accuracy of the movable support 2 during movement. The addition of the limiting plates 21 further enhances this effect, preventing the movable support 2 from deflecting or shaking.

[0030] When the utility model's water conservancy project pipeline leakage detection component is used:

[0031] Initial Setup and Piping Installation:

[0032] First, according to the length of the pipe to be detected, the two first screw rods 11 are driven to rotate by the first adjusting motor 12. Since the first screw rod 11 is threadedly connected to the movable vertical plate 112, the movable vertical plate 112 will move along the direction between the front vertical plate 111 and the rear vertical plate 13 until it is adjusted to a position suitable for the length of the pipe.

[0033] Next, the pipe to be inspected is placed on the inspection assembly using the rollers 24 on the mobile support 2. The height of the mounting frame 23 is adjusted by the second hydraulic cylinder 22 so that the pipe can be stably supported on the rollers 24 while reducing the pressure of the pipe on the turntable 14.

[0034] The design of the slide groove 10 and the limiting groove 101 ensures the stability and accuracy of the movable support 2 during the movement process, and the sliding connection between the limiting plate 21 and the limiting groove 101 prevents the movable support 2 from deflecting or shaking.

[0035] Pressure detection and leakage judgment:

[0036] The drive motor 110 is started to rotate the turntable 14 connected to the movable vertical plate 112, and the fan 3 is started to blow air or generate negative pressure to the center of the other turntable 14 through the air pipe 30. This will form a certain pressure or negative pressure environment inside the pipeline.

[0037] The first pressure sensor 140 detects the pressure changes on the turntable 14 in real time. These changes can reflect the pressure conditions inside the pipeline. If there is a leak in the pipeline, the pressure will change abnormally, so the reading of the first pressure sensor 140 can be used to determine whether there is a leak in the pipeline.

[0038] Accurate detection and positioning:

[0039] In order to further accurately detect the leakage location, the second adjusting motor 18 drives the second screw rod 17 to rotate. Since the second screw rod 17 is threadedly connected to the movable frame 15, the movable frame 15 will move up and down along the guide rod 16, driving the mounting plate 151 and the second pressure sensor 152 to approach or contact the inner wall of the pipe.

[0040] The first hydraulic cylinder 150 is used to precisely control the position of the mounting plate 151 so that it can fit tightly against the inner wall of the pipe. After fitting against the inner wall of the pipe, the second pressure sensor 152 can detect more subtle pressure changes, thereby helping to determine the specific location of the leak.

[0041] Comprehensive analysis and processing:

[0042] The leakage condition inside the pipeline is comprehensively analyzed based on the readings of the first pressure sensor 140 and the second pressure sensor 152 and the pressure or negative pressure generated by the fan 3.

[0043] If a leak is detected, the location can be recorded and repaired or further tested as needed.

[0044] End detection and cleanup:

[0045] After the detection is completed, the fan 3 and all motors are turned off, and the movable frame 15 and the mounting frame 23 are restored to their initial positions by the first hydraulic cylinder 150 and the second hydraulic cylinder 22 .

[0046] The movable support member 2 can slide out easily through the sliding groove 10 and the limiting groove 101 so as to remove the tested pipeline and prepare for the next test.

[0047] In summary, the water conservancy project pipeline leakage detection component of the present invention realizes accurate detection of the internal pressure of the pipeline through precise mechanical structure and sensor design, thereby determining whether there is leakage in the pipeline and accurately locating the leakage position, providing strong technical support for the maintenance and repair of water conservancy projects.
