Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a detection device for pressure pipeline leakage. Background Technology

[0002] Leak detection is an essential step in the manufacturing of pressure pipelines. Currently, leak detection in pressure pipelines involves filling the pipeline with air to test the pressure. However, while such detection devices can detect whether a pressure pipeline is leaking, they cannot accurately pinpoint the location of the leak. How to quickly detect leaks and determine the location of leaks is a problem that urgently needs to be solved by technicians in this field. To address this issue, we propose a leak detection device for pressure pipelines that can quickly detect leaks and accurately determine the location of leaks.

[0003] Currently, existing technology (CN 218725048 U) discloses a leak detection device for pressure pipeline inspection, including a base, a water tank, side support plates, and a lifting beam. The water tank is mounted on the base, and side support plates and rotating columns are fixed to both ends of the upper surface of the base, respectively. A lifting beam is fixed to the top of the side support plates, and a lifting drive is fixed to the lifting beam. A winding roller is fitted onto the output shaft of the lifting drive, and a lifting rope is wound on the winding roller. The bottom end of the lifting rope is connected to a hanger. Cylinders are fixed to both sides of the hanger, and an inflation tube is inserted into one of the compression plates. The beneficial effects of this leak detection device for pressure pipeline inspection are: the lifting drive lifts the pipeline on the hanger, and the cylinders and compression plates seal both ends of the pipeline. The pipeline can be quickly placed into the water tank, and air is inflated into the pipeline through the inflation tube. By simply observing whether bubbles emerge from the water, the presence of leaks in the pipeline can be quickly and intuitively detected, and the location of the leak can be accurately observed, improving practicality.

[0004] Using the above method, the pipe is raised and lowered by a rope during the inspection. After the inspection, a large amount of water remains on the surface of the pipe. As the rope rises and falls and the pipe swings, the water will spill onto the workbench, which not only contaminates the workbench and affects subsequent work, but may also pose safety hazards, such as slippery conditions leading to operational errors. It also increases the amount of cleaning work and the complexity of subsequent work. Utility Model Content

[0005] The purpose of this invention is to provide a pressure pipeline leakage detection device, which aims to solve the problem that residual water on the pipeline surface spills onto the workbench as the hoisting rope rises and falls and swings after pressure pipeline inspection.

[0006] To achieve the above objectives, this utility model provides a pressure pipeline leakage detection device, including a detection platform, a detection device body, and a waterproof mechanism. The waterproof mechanism includes a drive assembly, two threaded cylinders, two movable frames, and two protective covers. The main body of the detection device is installed on the detection platform, the drive assembly is installed inside the detection platform, the two threaded cylinders are respectively installed on the drive assembly, the two movable frames are respectively fixedly connected to the two threaded cylinders and are respectively located on the two threaded cylinders, and the two protective covers are respectively fixedly connected to the two movable frames and are respectively located on the two movable frames.

[0007] The driving assembly includes a driving component and a bidirectional threaded rod. The driving component is fixedly connected to the detection table and located inside the detection table. The bidirectional threaded rod is fixedly connected to the output end of the driving component, rotatably connected to the detection table, and fixedly connected to the two threaded cylinders.

[0008] The waterproofing mechanism further includes a guide rail and two guide blocks. The guide rail is fixedly connected to the testing platform and located inside the testing platform. The two guide blocks are respectively fixedly connected to the two movable frames and slidably connected to the guide rail, both located between the guide rail and the movable frames.

[0009] The waterproof mechanism further includes two mounting brackets and multiple dehumidifying fans. The two mounting brackets are fixedly connected to the two protective covers respectively and are located on the two protective covers. The multiple dehumidifying fans are fixedly connected to the two mounting brackets respectively and are located on the two mounting brackets.

[0010] The waterproof mechanism further includes two observation windows and two deflector plates. The two observation windows are fixedly connected to the two protective covers and are located on the two protective covers respectively. The two deflector plates are fixedly connected to the two protective covers and are located inside the two protective covers respectively.

[0011] This utility model discloses a pressure pipeline leakage detection device. The detection platform provides installation conditions for the detection device body and the waterproof mechanism. The detection device body can be used to detect pipelines. After the detection device body is completed, the drive component is activated. The drive component drives the two threaded cylinders to move closer to each other. The two threaded cylinders drive the two movable frames to move closer to each other. The two movable frames drive the two protective covers to move closer to each other until the two protective covers are released. After the water tank of the detection device body is closed, the detection device body can be activated to move the pipeline out of the water tank. After the pipeline dries, the protective covers are opened to remove the pipeline, thus preventing water splashing. This solves the problem that residual water on the pipeline surface spills onto the worktable as the hoisting rope rises and falls and swings after pressure pipeline detection.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1-3 This utility model provides a pressure pipeline leakage detection device, including a detection platform 1, a detection device body 2 and a waterproof mechanism, wherein the waterproof mechanism includes a drive assembly, two threaded cylinders 3, two movable frames 4 and two protective covers 5; The detection device body 2 is installed on the detection platform 1, the drive assembly is installed inside the detection platform 1, the two threaded cylinders 3 are respectively installed on the drive assembly, the two movable frames 4 are respectively fixedly connected to the two threaded cylinders 3 and are respectively located on the two threaded cylinders 3, and the two protective covers 5 are respectively fixedly connected to the two movable frames 4 and are respectively located on the two movable frames 4.

[0019] In this embodiment, the testing platform 1 provides installation conditions for the testing device body 2 and the waterproof mechanism. The testing device body 2 can be used to test the pipeline. After the testing of the testing device body 2 is completed, the drive component works, driving the two threaded cylinders 3 to move closer to each other. The two threaded cylinders 3 drive the two moving frames 4 to move closer to each other. The two moving frames 4 drive the two protective covers 5 to move closer to each other until the two protective covers 5 are released. After the water tank of the testing device body 2 is closed, the testing device body 2 can be activated to move the pipeline out of the water tank. After the pipeline dries, the protective covers 5 are opened to remove the pipeline, thus preventing water from splashing out. This solves the problem that residual water on the pipeline surface spills onto the worktable as the hoisting rope rises and falls and swings after pressure pipeline testing.

[0020] Furthermore, the driving assembly includes a driving component 12 and a bidirectional threaded rod 13. The driving component 12 is fixedly connected to the detection table 1 and located inside the detection table 1. The bidirectional threaded rod 13 is fixedly connected to the output end of the driving component 12, rotatably connected to the detection table 1, and fixedly connected to the two threaded cylinders 3.

[0021] In this embodiment, the operation of the drive assembly can drive the bidirectional threaded rod 13 to rotate. The rotation of the bidirectional threaded rod 13 can cause the two threaded cylinders 3 to move closer to each other or further away from each other, thereby causing the two protective covers 5 on the two movable frames 4 on the two threaded cylinders 3 to open or close.

[0022] Furthermore, the waterproofing mechanism also includes a guide rail 6 and two guide blocks 7. The guide rail 6 is fixedly connected to the testing platform 1 and located inside the testing platform 1. The two guide blocks 7 are respectively fixedly connected to the two movable frames 4 and respectively slidably connected to the guide rail 6, and are all located between the guide rail 6 and the movable frame 4.

[0023] In this embodiment, the guide rail 6 provides installation conditions for the two guide blocks 7. When the two threaded cylinders 3 move, they drive the two guide blocks 7 to slide on the guide rail 6. The two guide blocks 7 can guide and limit the two threaded cylinders 3, thereby improving the stability of the two threaded cylinders 3 when they move.

[0024] Furthermore, the waterproof mechanism also includes two mounting brackets 8 and multiple dehumidifying fans 9. The two mounting brackets 8 are respectively fixedly connected to the two protective covers 5 and are respectively located on the two protective covers 5. The multiple dehumidifying fans 9 are respectively fixedly connected to the two mounting brackets 8 and are respectively located on the two mounting brackets 8.

[0025] In this embodiment, the two mounting brackets 8 provide installation conditions for the multiple dehumidifying fans 9. After the pipeline inspection is completed, the multiple dehumidifying fans 9 are started, and the multiple dehumidifying fans 9 work to blow the water off the pipeline, thereby improving the drying efficiency of the pipeline.

[0026] Furthermore, the waterproof mechanism also includes two observation windows 10 and two guide plates 11. The two observation windows 10 are fixedly connected to the two protective covers 5 respectively and are located on the two protective covers 5 respectively. The two guide plates 11 are fixedly connected to the two protective covers 5 respectively and are located inside the two protective covers 5 respectively.

[0027] In this embodiment, the state of the pipes inside the two protective covers 5 can be observed through the observation window 10, and the water blown down by the multiple dehumidifying fans 9 can be guided into the water tank of the detection device body 2 through the two guide plates 11.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
