Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical liquid transportation pipeline testing technology, and in particular relates to a leak prevention detection device for chemical liquid transportation pipelines. Background Technology
[0002] Underground pipeline leak detectors can roughly pinpoint the location of a pipeline leak on the surface. Once the leak location is determined, excavation and repair can be carried out at that point, avoiding the need for full-line excavation and reducing maintenance costs.
[0003] Conventional pipeline leak detectors use a cane-shaped operating rod for the probe, allowing the operator to operate the probe while walking upright. However, since people have different heights, the operating frame is equipped with an adjustment mechanism. Because the conventional adjustment mechanism is located on the lower side, it requires squatting or bending over significantly to adjust, which makes adjusting the probe operating rod of conventional pipeline leak detectors quite troublesome.
[0004] To address this issue, we propose a leak detection device for chemical liquid transportation pipelines. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the cumbersome adjustment of the probe operating rod of conventional pipeline leak detectors, and to propose a leak prevention detection device for chemical liquid transportation pipelines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A leak detection device for chemical liquid transportation pipelines includes a pipeline leak detector probe. A guide column is fixedly connected to the upper end of the probe. A sliding sleeve is slidably fitted onto the guide column. A spring buckle is installed at the lower part of the sliding sleeve, and the lower part of the spring buckle matches the guide column. A handle is fixedly connected to the upper end of the sliding sleeve. A pull rope is fixedly connected between the spring buckle and the handle. An operating ring is fixedly connected to the pull rope. A stop block is fixedly connected to the tail of the handle. Holding the handle, with the thumb pressing on it and the middle and index fingers pinching the pull rope under the operating ring, and squeezing the operating ring upwards, pulls the pull rope upwards. This pull rope acts upwards on the lower part of the spring buckle, disengaging it from the guide column. Lifting the handle upwards causes the handle to lift the sliding sleeve. Pushing downwards lowers the handle and sliding sleeve. Releasing the operating ring allows the spring buckle to automatically engage with the guide column using its own elasticity. This method avoids the need for significant bending or squatting during adjustment, improving ease of adjustment.
[0008] Preferably, the guide column comprises a column body and a connecting column, the column body is uniformly provided with a buckle groove on the outside, the lower end of the column body is fixedly connected to the upper end of the connecting column, the upper end of the column body is in movable contact with the handle, the buckle groove is matched with the elastic buckle, and the lower end of the connecting column is fixedly connected with the pipeline leakage detector probe.
