[0016] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0017] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a hydraulic pipeline sealing test device, including a base plate 1. A pressure source 2 is installed on one side of the top of the base plate 1. A controller 3 is installed at the front end of the pressure source 2. A connecting pipe 4 is installed on one side of the controller 3. A placement frame 5 is installed at the top of the base plate 1. A pipeline body 6 is installed inside the placement frame 5. A connecting sleeve 7 is installed at one end of the pipeline body 6. The connecting pipe 4 and the connecting sleeve 7 are connected by a connecting flange 8. A side plate 11 is installed on one side of the top of the base plate 1. A fixing frame 10 is installed inside the side plate 11 on one side of the top of the base plate 1. A fixing mechanism is provided inside the fixing frame 10. A sealing mechanism is provided on one side of the side plate 11. A pressure sensor 9 is installed at the middle position of the pipeline body 6.

[0018] The sealing mechanism includes a cylinder 12, a movable plate 13, and a sealing gasket 14. The cylinder 12 is installed on one side of the side plate 11, with one end of the cylinder 12 extending to the inside of the side plate 11. The movable plate 13 is installed at one end of the cylinder 12, and the sealing gasket 14 is installed on the inside of the movable plate 13. In use, the cylinder 12 is activated to move the movable plate 13 and the sealing gasket 14, which together hold one end of the connecting sleeve 7 in place. The sealing gasket 14 seals one end of the connecting sleeve 7, making it more convenient and faster to test the hydraulic pipeline, thereby greatly improving the ease of use of the device.

[0019] The fixing mechanism includes a positioning plate 15, a servo motor 16, a threaded rod 17, a threaded sleeve 18, and a limiting structure. The positioning plate 15 is installed on one side of the top of the fixing frame 10, and the threaded rod 17 is installed on one side inside the fixing frame 10. The output end of the servo motor 16 is connected to one end of the threaded rod 17. A threaded sleeve 18 is provided on the outer wall of the threaded rod 17, and one end of the threaded sleeve 18 is connected to one side of the positioning plate 15. The bottom end of the inner side of the fixing frame 10 and the lower part of the positioning plate 15 are both arc-shaped. The arc-shaped fixing frame 10 and positioning plate 15 can clamp one end of the pipeline body 6. In use, the pipeline body 6 is placed on the fixing frame 15. Above 0, the servo motor 16 is started to drive the threaded rod 17 to rotate. Since the threaded rod 17 and the threaded sleeve 18 are threadedly connected, under the limit of the limit rod 19 and the limit sleeve 20, the threaded sleeve 18 drives the positioning plate 15 to move downward. The positioning plate 15 clamps the connecting sleeve 7. The inner sides of the positioning plate 15 and the fixing frame 10 are provided with plastic pads to protect the connecting sleeve 7. One end of the connecting sleeve 7 can be clamped and fixed, making it more convenient and quick to seal one end of the connecting sleeve 7. It also makes the pipeline body 6 more stable during the sealing test and the test results more accurate, thereby greatly improving the practicality of the device in use.

[0020] The limiting structure includes a limiting rod 19 and a limiting sleeve 20. The limiting rod 19 is installed inside the fixing frame 10 on one side. The limiting sleeve 20 is provided on the outer side wall of the limiting rod 19. One end of the limiting sleeve 20 is connected to one end of the positioning plate 15. The cross-section of the limiting rod 19 is smaller than the cross-section of the limiting sleeve 20. The limiting rod 19 and the limiting sleeve 20 form a sliding structure. In use, the mutual cooperation between the limiting rod 19 and the limiting sleeve 20 can limit the movement of the positioning plate 15, making the positioning plate 15 more stable when moving.

[0021] Working principle: The operator places the main pipe body 6 above the placement frame 5 and the fixing frame 10, then connects one end of the connecting sleeve 7 to one end of the connecting pipe 4 through the connecting flange 8. The servo motor 16 is then started to drive the threaded rod 17 to rotate. Since the threaded rod 17 and the threaded sleeve 18 are threadedly connected, under the limitation of the limiting rod 19 and the limiting sleeve 20, the threaded sleeve 18 drives the positioning plate 15 to move downwards, using the positioning plate 15 to clamp the connecting sleeve 7. Plastic pads are provided on the inner sides of both the positioning plate 15 and the fixing frame 10 to protect the connecting sleeve 7. Then, the cylinder 12 is started. The movable plate 13 and the sealing gasket 14 are moved to hold one end of the connecting sleeve 7 in place. The sealing gasket 14 seals one end of the connecting sleeve 7. At this time, gas is introduced into the interior of the pipeline body 6 through the pressure source 2 and the connecting pipe 4. The pressure sensor 9 monitors the pressure inside the pipeline body 6 in real time. If the pipeline body 6 is well sealed, the pressure will remain relatively stable for a certain period of time. If there is a leak, the gas will escape from the leak, causing the pressure to drop. The data acquisition and processing system will record and analyze the pressure change data to determine the sealing performance of the pipeline body 6.
