Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline leakage detection, and in particular relates to a pipeline damage repair pressurization leakage detection device. Background Art

[0002] A pipeline refers to a device used to transport gas, liquid or fluid with solid particles. During use, the pipeline may be damaged due to the external environment, causing the material in the pipeline to leak. The damaged pipeline needs to be repaired in time, but the damaged area is usually small and not easy to be discovered. Therefore, it is necessary to provide a pipeline leak detection device.

[0003] A Chinese patent with announcement number CN219102720U discloses a gas leakage detection device for a hydrogen-blended natural gas pipeline. The scheme includes an upper sleeve and a lower sleeve. The outer wall of the upper sleeve is equipped with a barometer connected to the interior of the upper sleeve. The above scheme utilizes the upper sleeve and the lower sleeve to be sleeved on the pipeline to enclose a closed space. When the pipeline is damaged, the reading of the barometer will change, thereby determining the damaged location of the pipeline.

[0004] In actual construction, pipelines generally have curved joints, but the above solution can only be installed on straight pipelines when used, and cannot perform damage and leak detection on curved pipelines. Utility Model Content

[0005] The utility model aims to provide a pipeline damage repair pressurization leak detection device to perform damage and leak detection on curved pipelines.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipeline damage repair pressurization leak detection device comprises a lower sleeve, an upper sleeve and a pressure gauge, the top of the lower sleeve has a groove, the upper sleeve is rotatably arranged on the top of the lower sleeve, and the bottom of the upper sleeve has a groove, the left and right ends of the lower sleeve and the upper sleeve are respectively symmetrically provided with notches, the axes of the two notches located at the same level form an angle, the front end of the lower sleeve is fixedly connected to the front end of the upper sleeve by a locking mechanism, the top of the upper sleeve is provided with a through hole, the top of the through hole is connected to a pressurization mechanism, and the pressure gauge is fixedly penetrated through the top of the upper sleeve.

[0008] The principle and effect of this technical solution:

[0009] Put the lower sleeve on the bottom of the pipe to be tested for leaks, and then rotate the upper sleeve to make the lower sleeve and the upper sleeve abut against each other on opposite sides. At this time, the notches on the left and right ends of the lower sleeve and the upper sleeve are respectively close to the pipe to be tested for leaks. The lower sleeve, the upper sleeve and the pipe to be tested for leaks form a closed space, and the booster mechanism pressurizes the closed space through the through hole. After standing still for a period of time, observe the changes in the pressure gauge readings to determine whether the pipe is damaged.

[0010] Through the above arrangement, the two notches located at the same level are arranged to form an angle between their axes, and the lower sleeve, the upper sleeve and the pipeline to be leak-detected are enclosed to form a closed space. The pressure change in the closed space is observed to determine whether the pipeline is damaged, so that the device can perform damage leak detection on curved pipelines.

[0011] In the utility model, the lower sleeve and the upper sleeve are respectively fixedly embedded with sealing strips outside the groove on the opposite sides. Through the above arrangement, the lower sleeve and the upper sleeve, the lower sleeve and the pipeline to be leak-checked, and the upper sleeve and the pipeline to be leak-checked can be tightly connected to avoid gaps and ensure the accuracy of the leak detection results.

[0012] The utility model further comprises a rubber strip, which is wound around the surface of the pipe to be leak-checked, the inner surface of each notch is set to be spherical, and the outer edge of the cross section of the rubber strip is set to be arc-shaped.

[0013] The principle and effect of this technical solution:

[0014] The rubber strip is wrapped around the side wall of the pipeline to be tested for leaks along the circumference of the pipeline to be tested for leaks, and then the lower sleeve is sleeved on the pipeline to be tested for leaks, and the notch is sleeved on the corresponding rubber strip. Since the outer edge of the cross section of the rubber strip is set to an arc shape, the outer surface of the rubber strip and the inner surface of the sealing strip in the notch fit together, and then the upper sleeve is rotated to connect the upper sleeve and the lower sleeve through the locking mechanism. During this process, the lower sleeve and the upper sleeve respectively push the corresponding sealing strip to press the rubber strip to enclose a closed space.

[0015] Through the above arrangement, the lower sleeve and the upper sleeve can enclose a closed space with pipes of various bending angles, so that the device can perform damage and leak detection on pipes of various bending angles, thereby broadening the applicable scenarios of the utility model.

[0016] In the utility model, the front walls of the lower sleeve and the upper sleeve are respectively fixed with connecting blocks, and the front walls of the two connecting blocks are respectively provided with connecting grooves. The locking mechanism includes a bolt rotatably set in one of the connecting grooves, and a nut cooperatedly sleeved on one end of the bolt, and the diameter of the circumscribed circle of the nut is larger than the inner wall spacing of the connecting grooves.

[0017] The principle and effect of this technical solution:

[0018] In the initial state, the bolt set in one of the connecting grooves is rotated to fall naturally. After the lower sleeve and the upper sleeve abut against each other on one side, the bolt is rotated to move one end of the bolt into the other connecting groove, and a nut is sleeved on one end of the bolt until the end wall of the nut abuts against the outer surface of the other connecting block.

[0019] Through the above arrangement, by rotating the nut sleeved on one end of the bolt to make it abut against the outer surface of the other connecting block, the front end of the lower sleeve and the front end of the upper sleeve can be prevented from separating from each other during the detection process, thereby ensuring the accuracy of the leak detection effect.

[0020] In the utility model, the two ends of the rubber strip are magnetically connected. After the rubber strip is wound around the pipeline to be leak-checked, the two ends of the rubber strip are magnetically connected. The above arrangement can prevent the rubber strip from falling off the surface of the pipeline to be leak-checked, thereby improving the detection efficiency.

[0021] In the utility model, the rear end of the lower sleeve and the rear end of the upper sleeve are rotatably connected via a hinge. Through the above arrangement, the purpose of making the upper sleeve rotatably arranged on the top of the lower sleeve is achieved.

[0022] In the present invention, a one-way valve is provided at the bottom of the through hole. Through the above arrangement, after the booster mechanism pressurizes the enclosed space, the gas in the enclosed space can be prevented from flowing out of the through hole, further ensuring the accuracy of the detection result.
