Description

Technical Field

[0001] The utility model relates to the technical field of pipeline water tightness tests, and in particular to a pipeline water tightness test device. Background Art

[0002] The water tightness test is also called the water storage test. Enough water needs to be filled to have sufficient volume to detect the leakage degree of pipelines and other objects. In municipal engineering, water tightness tests need to be carried out on pipelines with design requirements such as sewage pipelines.

[0003] In the prior art, when performing a water tightness test on a sewage pipeline or the like, first, the inspection wells at both ends of a certain section of the sewage pipeline are sealed, and then water is injected into the sewage pipeline through the inspection wells. When the water level in the sewage pipeline reaches a certain height, the water injection is stopped. After a period of time, the operator measures the water level drop and then calculates the water seepage volume in combination with the water precipitation area to determine whether the sewage pipeline meets the design requirements.

[0004] However, in the above operation, due to the change in the cross-sectional area of the sewage pipeline, it is inconvenient to detect the water seepage volume, thereby reducing the accuracy of the detection result. Summary of the Utility Model

[0008] By adopting the above technical solution, when a pipeline closed water test is required, first, the operator manually places the cylinder in the inspection well. When all the installation blocks are in contact with one end of the inspection well, the cylinder is fixed by the fixing component. After a certain amount of water is injected into the pipeline, at this time, the floating box moves vertically upward under the buoyancy force generated by the water in the pipeline.

After the detection is completed, the operator manually drives the connecting pipe to rotate. When the connecting pipe is separated from the partition plate, the water in the cylinder can be easily discharged.

[0015] Preferably, a second sliding groove is formed in the inner wall of the first sliding groove, and a pulley is movably arranged on the inner wall of the second sliding groove. The pulley is installed on the outer side wall of the floating box.

[0021] Preferably, a relief groove is formed in the inner wall of the first sliding groove.

[0022] By adopting the above technical solution, when the floating box drives the block to move in the vertical direction, through the arrangement of the relief groove, it is possible to easily reduce the adsorption effect of the first sliding groove on the block, so as to easily drive the block to move.

The stop block 15 can be abutted against the inner wall of the first through groove 12. The stop block 15 is welded on the outer side wall of the floating box 11.

[0035] As Figure 1 and Figure 2 shown, four mounting blocks 16 are uniformly welded on one end of the cylinder 1 along the circumferential direction. The mounting blocks 16 are square. A connecting block 17 is welded on the side wall of the mounting block 16. The connecting block 17 is square. A fixing component 2 for fixing the cylinder 1 is arranged on the side wall of the connecting block 17. Four connecting components 4 for communicating the two sides of the partition board 13 are arranged on the side wall of the partition board 13.

[0036] When a pipeline closed - water test is required, first, the operator manually places the cylinder 1 into the inspection well. When all the installation blocks 16 are in contact with one end of the inspection well, the cylinder 1 is fixed by the fixing component 2. After a certain amount of water is injected into the pipeline, at this time, the floating box 11 moves vertically upward under the buoyancy force generated by the water in the pipeline. The floating box 11 drives the stop block 15 to move vertically. When the stop block 15 is in contact with the inner wall of the first through - slot 12, the water injection stops. Then, a certain amount of water is injected into the cylinder 1. After a period of time, when some water seeps out of the pipeline, the water level in the pipeline drops. The floating box 11 moves vertically downward under the action of gravity. The floating box 11 drives the stop block 15 to move. When the stop block 15 is separated from the inner wall of the first through - slot 12, the water in the cylinder 1 flows into the pipeline through the first through - slot 12, thus facilitating the re - achievement of the above - mentioned equilibrium state. By repeating the above operations, after a period of time, by detecting the amount of water flowing out of the cylinder 1, the accuracy of the detection result can be improved.

[0037] As Figure 1 shown, the fixing component 2 includes a lead screw 21. The lead screw 21 is arranged radially along the cylinder 1.

The cross - section of the fixing block 22 is fan - shaped and is arranged vertically. The lead screw 21 passes through the fixing block 22. The fixing block 22 can be in contact with the side wall of the inspection well. A handle 23 is welded to the end of the lead screw 21 away from the fixing block 22. The cross - section of the handle 23 is circular and is arranged along the axial direction of the lead screw 21. A guiding component 3 for guiding the fixing block 22 is arranged on the connecting block 17.

[0038] When the cylinder 1 needs to be fixed, at this time, the installation block 16 is in contact with the side wall of the inspection well. First, the operator manually drives the handle 23 to rotate. The handle 23 drives the lead screw 21 to rotate. The lead screw 21 drives the fixing block 22 to move towards the inspection well. At the same time, through the guiding action of the guiding component 3, it is convenient to drive the fixing block 22 to move in a straight line. When all the fixing blocks 22 are in contact with the side wall of the inspection well, the cylinder 1 can be fixed conveniently.

[0039] As Figure 1 shown, the guiding component 3 includes a guiding rod 31. The cross - section of the guiding rod 31 is circular and is arranged along the axial direction of the lead screw 21. The guiding rod 31 is welded to the side wall of the connecting block 17 close to the fixing block 22. The guiding rod 31 is in sliding fit with the fixing block 22. The guiding rod 31 passes through the fixing block 22. When the fixing block 22 needs to be guided, through the setting of the guiding rod 31, it is convenient to reduce the possibility of the fixing block 22 rotating during the movement, thus facilitating the driving of the fixing block 22 to move in a straight line.

[0040] As Figure 4 andFigure 5 As shown, the connecting member 4 includes a connecting pipe 41. The cross-section of the connecting pipe 41 is annular and arranged in the vertical direction. A second through groove 42 is formed in the side wall of the partition plate 13. The cross-section of the second through groove 42 is circular and extends in the vertical direction. The outer side wall of the connecting pipe 41 is in threaded fit with the inner wall of the second through groove 42. A first sealing gasket 43 is sleeved on the outer side wall of the connecting pipe 41. The cross-section of the first sealing gasket 43 is annular and arranged in the vertical direction. There is a gap between the floating box 11 and the inner wall of the cylinder 1.

[0041] When a certain amount of water is injected into the cylinder 1, due to the arrangement of the connecting pipe 41, it is convenient to keep the air pressure at one end of the cylinder 1 close to the floating box 11 consistent with the atmospheric pressure. After the detection is completed, the operator manually drives the connecting pipe 41 to rotate. When the connecting pipe 41 is separated from the partition plate 13, it is convenient to drain the water in the cylinder 1.

[0042] As Figure 2 and Figure 4 shown, a second sliding groove 44 is formed in the inner wall of the first sliding groove 14. The cross-section of the second sliding groove 44 is square and extends in the vertical direction. A pulley 45 is movably arranged in the inner wall of the second sliding groove 44.

The cross-section of the second sealing gasket 47 is fan-shaped and arranged in the vertical direction. When the floating box 11 drives the stop block 15 to abut against the inner wall of the first through groove 12, due to the arrangement of the second sealing gasket 47, it is convenient to seal the water in the cylinder 1.

[0045] As Figure 2 and Figure 3 shown, a relief groove 48 is formed in the inner wall of the first sliding groove 14. The cross-section of the relief groove 48 is square and extends in the vertical direction. When the floating box 11 drives the stop block 15 to move in the vertical direction, due to the arrangement of the relief groove 48, it is convenient to reduce the adsorption effect of the first sliding groove 14 on the stop block 15, so as to facilitate driving the stop block 15 to move.

[0046] The implementation principle of a pipeline water-tightness test device in an embodiment of the present application is as follows:

[0047] When a pipeline closed water test is required, first manually place the cylinder 1 into the inspection well by the operator. When multiple mounting blocks 16 all abut against one end of the inspection well, then fix the cylinder 1 through the fixing member 2. After a certain amount of water is injected into the pipeline, at this time, the floating box 11 moves vertically upward under the buoyancy force generated by the water in the pipeline. The floating box 11 drives the stop block 15 to move vertically. When the stop block 15 abuts against the inner wall of the first through groove 12, stop injecting water at this time. Then inject a certain amount of water into the cylinder 1. After a period of time, when some water seeps out of the pipeline, at this time, the water level in the pipeline drops. The floating box 11 moves vertically downward under the action of gravity. The floating box 11 drives the stop block 15 to move. When the stop block 15 separates from the inner wall of the first through groove 12, at this time, the water in the cylinder 1 flows into the pipeline through the first through groove 12, so that it is convenient to reach the above balance state again. Repeat the above operation. After a period of time, by detecting the amount of water flowing out of the cylinder 1, it is convenient to improve the accuracy of the detection result.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly.
