Technical Field

[0001] This utility model relates to the field of pipeline leak detection testing technology, specifically, to a pipeline water leak detection testing device. Background Technology

[0002] In the fields of industrial production and infrastructure, pipeline systems are widely used in industries such as petrochemicals, power, water supply and drainage, and aerospace, undertaking the important task of transporting various fluid media.

[0003] After production is completed, the pipeline needs to be tested for leaks during subsequent use to prevent leaks. The existing testing method usually involves fixing the pipeline in a testing device, filling the pipeline with water, and then continuously pressurizing the water in the pipeline. If there is a leak in the pipeline, water will spray out. When the pipeline is removed after testing, the water in the pipeline can easily spill everywhere, which not only wastes water resources but also affects the testing environment. Utility Model Content

[0004] This invention proposes a pipeline water leak detection test device, which solves the problem in the prior art that when the pipeline is disassembled after testing, the water inside the pipeline is easily spilled everywhere, which not only wastes water resources but also easily affects the testing environment.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-4 As shown, this embodiment proposes a pipeline water leak detection test device, including a test box 1, and also includes a lifting plate 2. The lifting plate 2 is set on the test box 1 by a lifting mechanism. Two movable frames 3 are set on the lifting plate 2 by a moving mechanism. A moving groove is opened on the lifting plate 2. The two movable frames 3 are slidably connected in the moving groove. A pressurizing mechanism is provided on the two movable frames 3. A support mechanism is slidably connected on the test box 1.

[0021] The pressurization mechanism includes: a pressurization head 4, multiple pressurization heads 4 on each of the two movable frames 3, a pipe rack 5 connecting each pair of adjacent pressurization heads 4, an air pipe 6 connecting the two pipe racks 5, an air pump 7 installed on the test box 1, the output end of the air pump 7 connected to the air pipe 6, the two ends of the pipe are blocked by the pressurization heads 4 on the two movable frames 3, and then the compressed gas in the air pump 7 is delivered into the pipe rack 5 through the air pipe 6, and the gas is injected into the pipe through the pressurization head 4 through the pipe rack 5, thereby facilitating the inflation of the pipe.

[0022] The support mechanism includes: a support plate 8, a sliding groove on the test box 1, the support plate 8 being slidably connected in the sliding groove, a base plate 9 being fixedly connected inside the test box 1, the support plate 8 being in contact with the base plate 9, and before testing the pipeline, multiple pipelines are placed on the top of the support plate 8 and positioned so that the pressure head 4 can quickly clamp the multiple pipelines.

[0023] The moving mechanism includes: a bidirectional screw 10, which is rotatably connected to the top of the lifting plate 2. Both moving frames 3 have screw holes, and the bidirectional screw 10 is threaded into the screw holes. A first motor 11 is installed on the lifting plate 2. The output end of the first motor 11 is fixedly connected to one end of the bidirectional screw 10. The first motor 11 drives the bidirectional screw 10 to rotate. When the bidirectional screw 10 rotates, it drives the two moving frames 3 to move relative to each other, thereby driving the pressure heads 4 on the two moving frames 3 to block both ends of the pipeline and clamp the pipeline.

[0024] The lifting mechanism includes: a lifting frame 12, two lifting frames 12 fixedly connected to the lifting plate 2, two sliding rods 13 fixedly connected inside the detection box 1, the two lifting frames 12 being slidably connected to the two sliding rods 13 respectively, and two first electric cylinders 14 installed on the detection box 1. The output ends of the two first electric cylinders 14 are fixedly connected to the two lifting frames 12 respectively. The first electric cylinders 14 drive the lifting frame 12 and the lifting plate 2 to descend, thereby causing the fixed pipeline to descend into the detection box 1, which facilitates the detection of the pipeline by the water in the detection box 1.

[0025] In this embodiment, when leak detection of the pipeline is required, the detection box 1 is first filled with water. Then, multiple pipelines to be tested are placed on top of the support plate 8 and positioned. Next, the first electric cylinder 14 drives the lifting frame 12 and the lifting plate 2 to descend. When the lifting plate 2 descends, it drives the two moving frames 3 and the pressure heads 4 set on the two moving frames 3 to descend as well. After the pressure heads 4 on both sides are aligned with the two ends of the pipeline, the lifting plate 2 stops descending. Then, the first motor 11 drives the bidirectional screw 10 to rotate. When the bidirectional screw 10 rotates, it drives the two moving frames 3 to move relative to each other, thereby causing the pressure heads 4 on the two moving frames 3 to block the two ends of the pipeline. The pipeline is clamped, and after the pipeline is clamped, the operator needs to pull the support plate 8 out of the test box 1 in the slide groove. Then, the compressed gas in the air pump 7 is delivered into the pipe rack 5 through the air pipe 6. The gas is injected into the pipeline through the pressurizing head 4 through the pipe rack 5, which facilitates the inflation of the pipeline. During this process, the first electric cylinder 14 drives the lifting frame 12 and the lifting plate 2 to continue to descend, so that the pipeline descends into the test box 1 and is immersed in water. If there is a leak in the pipeline, bubbles will appear in the water. After the pipeline is finished, the pipeline is raised out of the test box 1. During this process, the pipeline will not carry too much water, reducing the waste of water resources and not easily affecting the test environment.

[0026] It should also be noted that the conical surface of the pressure head 4 is made of rubber, which can seal the pipe opening when it is pressed against the pipe. The conical design of the pressure head 4 can accommodate pipes of different diameters. In addition, the pressure head 4 has a vent hole that is connected to the pipe support 5, so that air can be injected into the pipe.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
