Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a pipeline micro-leakage detection terminal. Background Technology

[0002] Pipelines are tubular structures used to transport fluids or solid particles, widely used in industry, construction, agriculture, energy, and other fields. They are critical infrastructure connecting production, storage, transportation, and use. During use, because most pipelines are made of steel, they are prone to internal cracks when subjected to impact or corrosion, leading to material leakage. These cracks are difficult to detect with the naked eye. However, a pipeline micro-leakage detection device (CN219956814U) improves the detection of pipeline micro-leakage by using moisture test paper in conjunction with a water tank. This allows for direct observation of the specific location of pipeline cracks during testing, reducing the likelihood of internal material leakage during use. The inclusion of a limiting groove enhances the fixation of the test pipeline, reducing swaying within the groove.

[0003] While the aforementioned technology can detect minor leaks in pipelines, it suffers from low detection efficiency. During detection, the test paper needs to be manually wrapped around the outer surface of the pipeline. When manually wrapping the test paper, it is difficult to ensure that the test paper adheres completely to the pipeline surface, especially on rough pipeline surfaces, sections with welds, or bends, where gaps are easily formed. Minor leaks of gas or liquid may escape through these gaps, failing to make sufficient contact with the test paper. Furthermore, the operation is time-consuming, resulting in low detection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline micro-leakage detection terminal to solve the problem of low detection efficiency of current detection devices on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline micro-leakage detection terminal, including an operating table, with support members at both ends of the top of the operating table, and support frames on both sides of the top of the operating table. A drive motor is installed at one end of each of the two support frames, and the output end of each drive motor is provided with a threaded rod rotatably connected inside the support frame. A slider is slidably connected inside each of the two support frames, and the two sliders are threadedly connected to the two threaded rods respectively. A protrusion is provided on the top of each of the two sliders, and a liquid storage tank is provided on the top of each of the two protrusions. A hollow ring is provided between the two support frames, and a nozzle is connected to the inner side of the hollow ring. A water pump is provided inside each of the two liquid storage tanks, and the output ends of the two water pumps are connected to the hollow ring through hollow pipes respectively. A swinging component is provided on the slider to drive the hollow ring to swing. A cleaning component is provided between the support frames to clean the pipeline surface.

[0006] Preferably, the swing assembly includes two rotating columns rotatably connected inside the two sliders respectively. Each of the two sliders has a support plate on one side. One end of each of the two support plates is rotatably connected to a swing frame via a rotating shaft. One end of each of the two swing frames is provided with a connecting column, and the ends of the two connecting columns away from the swing frames are respectively connected to the two ends of the hollow ring.

[0007] Preferably, the two rotating columns pass through the two support plates and are provided with turntables, and one end of each of the two turntables is fixedly connected to a protruding column provided inside the two swing frames.

[0008] Preferably, each of the two rotating columns is provided with a gear at the end away from the turntable, and each of the two support frames is provided with a rack that meshes with the two gears on one side.

[0009] Preferably, the cleaning assembly includes two bent rods respectively disposed at one end of the two support plates, and each of the two bent rods having a support ring at the end closest to each other.

[0010] Preferably, each of the two support rings has a spring on its inner side, and the other end of each spring is connected to a cleaning ring, and the center of the two cleaning rings and the center of the hollow ring are at the same height.

[0011] Preferably, the centers of the two support members and the center of the hollow ring are at the same height, and the bottom of the operating table is provided with support legs on all four sides, and the four support legs are arranged symmetrically.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The drive motor moves the slider, which in turn moves the hollow ring. Then, the nozzle sprays soap solution onto the pipe surface automatically, which helps to detect micro-leaks in the pipe. This reduces manual intervention, lowers labor intensity, and the automated spraying provides fast coverage, thereby improving detection efficiency.

[0014] By using the swinging component, the hollow ring can swing back and forth when it moves. A hollow ring sprayed in a fixed direction is difficult to cover the bolt gaps on the flange side of the pipeline, branch interfaces, and the undercut and depressions of the weld seam. It is easy to miss the leaks because the soap solution does not come into contact with the leak points. However, the swinging hollow ring can drive the nozzle to sweep across the interface area, ensuring that the soap solution penetrates into the gaps, depressions and other dead corners, thereby improving the detection effect.

[0015] The cleaning components effectively clean the pipe surface. Impurities such as rust, oil, dust, and welding slag on the pipe surface can form an isolation layer, preventing soap solution from making close contact with the pipe surface and interfering with detection. The cleaning components can remove these impurities, making the pipe surface smooth. The soap solution can then adhere evenly and form a continuous film, allowing bubbles from minor leaks to be stably detected and reducing the false negative rate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: a pipeline micro-leak detection terminal:

[0025] Example 1: To address the problem of low detection efficiency in existing detection devices, the following is disclosed: an operating table 1, with support members 2 at both ends of the top of the operating table 1, and support frames 3 on both sides of the top of the operating table 1. A drive motor is installed at one end of each support frame 3, and the output end of each drive motor is provided with a threaded rod rotatably connected inside the support frame 3. A slider 4 (e.g., ...) is slidably connected inside each support frame 3. Figures 1-6 As shown), the two sliders 4 are threadedly connected to the two threaded rods respectively. Each slider 4 has a protrusion 5 on its top, and each protrusion 5 has a liquid storage tank 6 on its top. A hollow ring 7 is provided between the two support frames 3, and a nozzle 8 is connected to the inner side of the hollow ring 7 (as shown). Figures 1-3 and Figure 6 As shown), each of the two liquid storage tanks 6 is equipped with a water pump, and the output ends of the two water pumps are connected to a hollow tube and a hollow ring 7 respectively, for discharging soap solution into the hollow ring 7. The slider 4 is equipped with a swing assembly that drives the hollow ring 7 to swing. The swing assembly includes two rotating columns 9 rotatably connected to the inside of the two sliders 4 respectively. Each of the two sliders 4 has a support plate 10 on one side, and one end of each support plate 10 is rotatably connected to a swing frame 13 (e.g., as shown) via a rotating shaft. Figure 4 and Figure 6 As shown), each of the two swing frames 13 has a connecting post 14 at one end, and the ends of the two connecting posts 14 away from the swing frame 13 are respectively connected to the two ends of the hollow ring 7, for driving the hollow ring 7 to swing back and forth. Two rotating posts 9 pass through the two support plates 10 and are equipped with turntables 11. One end of each of the two turntables 11 is fixedly connected to a protruding post 12 located inside the two swing frames 13. The ends of the two rotating posts 9 away from the turntables 11 are each equipped with gears 15 (such as...). Figures 1-5 As shown), one side of each of the two support frames 3 is provided with a rack 16 that meshes with the two gears 15. The center of the two support members 2 and the center of the hollow ring 7 are at the same height. Support legs are provided around the bottom of the operating table 1, and the four support legs are symmetrically arranged to support the operating table 1.

[0026] Place the pipe to be tested on top of the two supports 2, then seal one end of the pipe and allow compressed air to enter the pipe from the other end. Then start the water pump to discharge soap solution into the hollow ring 7 through the hollow tube (e.g., Figures 1-3 and Figure 6 As shown), it is then sprayed from nozzle 8 and sprayed around the perimeter of the pipe surface. The drive motor is then activated, causing the threaded rod to rotate. This, in turn, causes the slider 4 and protrusion 5 to move within the support frame 3. As the slider 4 moves, it also drives the gear 15 to rotate under the action of the rack 16, further rotating the rotating column 9. This, in turn, causes the turntable 11 to rotate, further moving the protrusion 12 within the swing frame 13. This causes the swing frame 13 to reciprocate around the rotating shaft (as shown). Figure 4 As shown), under the action of the connecting column 14, it drives the hollow ring 7 to move and swing back and forth, thereby improving the coverage effect of the soap solution. Then, the operator observes the surface of the pipe. If there is a micro-leak, the leaking gas will form bubbles through the soap solution film. The leak point can be located by the position of the bubbles. When it is necessary to check the side of the pipe facing the operating table 1, the pipe can be rotated so that it rotates on the surface of the support 2. The side of the pipe facing the operating table 1 can be turned to the upward position. The support 2 can ensure that the pipe and the hollow ring 7 are concentric, avoiding uneven spraying caused by eccentricity.

[0027] Example 2: Unlike Example 1, the cleaning component can clean the pipe surface. It is disclosed that a cleaning component for cleaning the pipe surface is provided between the support frames 3. The cleaning component includes two bending rods 17 respectively disposed at one end of the two support plates 10 (e.g., Figure 1 and Figure 3 As shown), each of the two bent rods 17 has a support ring 18 at one end close to each other. Each support ring 18 has a spring inside it, and the other end of each spring is connected to a cleaning ring 19 (as shown). Figures 1-3 As shown), it is used to clean the pipe, and the center of the two cleaning rings 19 and the center of the hollow ring 7 are at the same height.

[0028] When placing the pipe on the support 2, the pipe can first be passed between the two cleaning rings 19. The cleaning rings 19 will then fit tightly against the pipe surface under the action of the spring. Subsequently, when the slider 4 moves, it will also move the bending rod 17 under the action of the support plate 10, thereby further moving the two support rings 18 (e.g., ...). Figures 1-3 As shown), the cleaning ring 19 then moves further along the pipe surface, thereby cleaning impurities such as rust, oil, dust, and welding slag from the pipe surface. The center of the cleaning ring 19 is at the same height as the center of the hollow ring 7 (as shown). Figures 1-3As shown, this ensures that the pipe is coaxial with the cleaning ring 19 when it passes through, avoiding eccentric friction. After the inspection is completed, when the slider 4 is reset, it will drive the cleaning ring 19 to clean the surface of the pipe again, thereby removing the soap solution from the surface of the pipe and preventing it from remaining on the surface of the metal pipe for a long time and reacting with oxygen and moisture in the air to cause electrochemical corrosion.
