Description

Technical Field

[0001] The utility model relates to the field of water conservancy pipelines, in particular to an adjustable water conservancy pipeline. Background Art

[0002] The main function of water conservancy pipelines is to transport water and ensure water supply and distribution. They are an important part of infrastructure such as cities and agricultural irrigation. They can effectively transport water from water sources to where it is needed to meet people's daily life needs and agricultural irrigation needs. In addition, water conservancy pipeline systems also help regulate water flow, ensure the rational use of water and avoid waste.

[0003] After searching, Chinese patent announcement number: CN221075304U discloses a water conservancy pipeline with adjustable flow. By rotating the flow regulator, the flow regulator drives the second flow limiting plate to rotate. During the rotation process, the center holes on the first flow limiting plate and the second flow limiting plate are always in a corresponding state to ensure that the pipeline body can always ensure water flow and is in a minimum flow state. Then, the overlap between the side holes on the second flow limiting plate and the first flow limiting plate and between the side holes is adjusted to achieve flow regulation.

[0004] In the above technical solution, the water flow rate of the hydraulic pipeline can be adjusted by two sets of flow limiting plates. However, when the hydraulic pipeline is installed, the overall length of the pipeline cannot be adjusted and the unidirectional length of the pipeline cannot be changed, so it cannot adapt to different on-site installation requirements, reducing the efficiency of pipeline installation. Therefore, an adjustable hydraulic pipeline is proposed to solve the above problems. Utility Model Content

The hand-cranked wheel 5 can control the rotation direction of the bidirectional screw rod 6, so that the two groups of movable seats 8 are close to or away from each other. The outer wall of the bidirectional screw rod 6 is threadedly connected to the movable seat 8, and the lower surface of the pipe 2 is fixedly connected to a connecting block 14, and the inner wall of the connecting block 14 is slidably connected to a limiting rod 13. The two ends of the limiting rod 13 are fixedly connected to the inner wall of the second group of through grooves 7, and an adjustment component is arranged on the surface of the movable seat 8.

[0034] Reference Figure 4-Figure 6 The outer wall of the movable seat 8 fits with the outer wall of the sleeve 3, the left end of the bellows 4 is fixedly connected to the right end of the pipe 1, and the right end of the bellows 4 is fixedly connected to the left end of the pipe 2. The bellows 4 connects the pipe 1 with the pipe 2. The adjustment component includes a threaded rod 9, the outer wall of the threaded rod 9 is threadedly connected to the inner wall of the slide seat 10, the upper surface of the pipe 2 is fixedly connected with a slide rail 11, and the outer wall of the slide rail 11 is slidably connected with the slide seat 10, and the slide seat 10 cannot follow after being separated from the threaded rod 9. The movable seat 8 moves, and threaded holes 12 are provided on the upper surface of the slide rail 11. There are several groups of threaded holes 12, and the several groups of threaded holes 12 are equidistantly distributed on the upper surfaces of the two groups of slide rails 11. The upper surface of the slide seat 10 is fixedly connected to the lower surface of the movable seat 8, and the outer wall of the threaded rod 9 is threadedly connected to the inner wall of the threaded hole 12. The threaded rod 9 can fix the slide seat 10 on the slide rail 11 so that it cannot move on the slide rail 11.

[0036] Working principle: when it is necessary to adjust the distance between pipe 1 and pipe 2, manually turn the hand wheel 5 forward or reverse, the hand wheel 5 drives the bidirectional screw 6 to rotate, so that the two groups of moving seats 8 drive the two groups of sliding seats 10 to move, and at this time the two groups of connecting blocks 14 can be driven to slide on the limit rod 13, so that pipe 1 and pipe 2 are close to or away from each other, and the corrugated tube 4 is stretched or contracted, so as to change the overall length of the pipe. When only the position of pipe 1 or pipe 2 needs to be adjusted, according to the adjustment needs, for example, when adjusting the position of pipe 2, first reverse the threaded rod 9 close to pipe 1 to make it gradually move. Gradually disengage from the threaded hole 12 until it disengages from the sliding seat 10 and the moving seat 8 in turn, and then the hand wheel 5 is turned. When the hand wheel 5 is turned, the bidirectional screw 6 drives the two groups of moving seats 8 to move. Since the sliding seat 10 on the pipe 1 is not fixed to the moving seat 8, the position of the pipe 2 is moved, and vice versa, the position of the pipe 1 can be changed, so that the length of the entire pipe can be adjusted according to the on-site installation requirements. When the bellows 4 is used for water transportation, its telescopic characteristics will generate a certain vibration force. The sponge pads 18 on both sides of the sleeve 3 can absorb the vibration force. At the same time, the annular airbag 16 ensures that the bellows 4 fits with the sponge pad 18 when it is stretched to the extreme.
