Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas detection, in particular to a gas leakage detection device. Background Art
[0002] Gas is an indispensable combustible fuel in daily life and is transported to thousands of households through pipelines.
[0003] As a flammable gas, natural gas is inherently dangerous. When gas leaks and encounters an open flame, an explosion will occur. Even if no explosion occurs, the gas contains many chemical elements. These chemical elements will enter the human body and cause certain damage to human body functions. According to observations based on existing technologies, during the detection process, the inspectors hold the detector and aim the detection port at the pipeline for scanning. The value fed back by the sensor during the scan is used to determine whether there is a leak in the pipeline. However, this detection method has some disadvantages. Most of the places where gas pipelines leak are at the connection points of the pipelines. If there is an opening at the connection point of the pipeline, when the gas leaks, it will form an extrusion spray phenomenon due to the small position of the pipeline opening. The sprayed gas will cover the surrounding area and is difficult to evaporate in a short time. Therefore, it is necessary to conduct repeated detection and scanning of the area. In this way, it is difficult for the detector to quickly detect the location of the leak during the scanning, and the mixing of other gases during the detection will also affect the detection value of the detection instrument, thereby affecting the judgment of the inspectors.

[0011] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0012] 1. The utility model is provided with a sealing ring and a drainage groove. First, detection is performed according to the range of gas leakage. When an area with a larger value is detected, the first clamping ring and the second clamping ring are opened to wrap and clamp the connection of the pipeline close to the pipeline connection.

DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0020] A gas leak detection device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.
[0021] Combination Figure 1-3 As shown, a gas leak detection device provided by the utility model includes a control box 1, one end of the control box 1 is fixedly connected with a hose 2 in a connected state, one end of the hose 2 is fixedly connected with a connecting pipe 3, one side of the connecting pipe 3 is fixedly connected with a first clamping ring 4 in a connected state, one side of the first clamping ring 4 is fixedly connected with a first hinge 5, one end of the first hinge 5 is fixedly connected with a second clamping ring 6, the inner walls of the first clamping ring 4 and the second clamping ring 6 are fixedly connected with a sealing ring 7, the bottom position of the sealing ring 7 is provided with an opening, the inner wall of the sealing ring 7 is provided with a drainage groove 8, the inner wall of the drainage groove 8 is fitted and slidably connected with a moving ring 9, the bottom of the first clamping ring 4 and the second clamping ring 6 are fixedly connected with a connecting plate 10, the side wall of the connecting plate 10 is threadedly connected with a clamping bolt 11 in a through-shape, and the number of the clamping bolts 11 is three, a handle 21 is fixedly connected to one side of the control box 1, and a display screen 20 is fixedly connected to one side of the control box 1.
[0022] In the first embodiment, the connecting pipe 3 on the hose 2 is brought close to the pipeline to first check the approximate range of the leakage. If it is close to the pipeline connection, the first clamping ring 4 and the second clamping ring 6 are clamped on the pipeline connection, and then the sealing ring 7 will wrap the pipeline. After wrapping, the leaked gas will enter the connecting pipe 3 along the drainage groove 8. In this way, the extracted gas has a higher purity, and it can quickly distinguish whether it is residual gas when leaking from other parts or gas leaking from the pipeline connection. The gas purities of the two are different. Using purity to distinguish the location of the gas leak is conducive to the detection personnel to make a quick judgment, which is conducive to improving the detection efficiency and accuracy of the detection personnel.
[0023] An anti-leakage mechanism is provided inside the sealing ring 7, and the anti-leakage mechanism includes an airbag 12, which is symmetrically arranged inside the sealing ring 7, one side of the airbag 12 is fixedly connected to a movable ring 9, one end of the airbag 12 is slidably connected to a sliding rod 13 in a through-shaped manner, and the inner wall of the sealing ring 7 is provided with a silicone tube 19 in a ring shape, one end of the sliding rod 13 is fixedly connected to a push block 14, one end of the push block 14 is slidably connected to an extrusion block 15, one side of the extrusion block 15 is fixedly connected to a sealing ring 16, a second hinge 17 is fixedly connected between the sealing rings 16, one end of the sealing ring 16 is fixedly connected to a magnet 18, and the magnetic poles of the magnet 18 are opposite, and both sides of the extrusion block 15 are fixedly connected to blocks 22, and one side of the block 22 is fixedly connected to a spring 23, and one end of the spring 23 is fixedly connected to the inner wall of the sealing ring 16.
[0024] In the second embodiment, when the sealing ring 7 is being merged, it will squeeze the moving ring 9. When the moving ring 9 is moving, it can push the airbag 12. When the airbag 12 is squeezed, it will use the gas to drive the sliding rod 13 to move. When the sliding rod 13 moves, it can drive the push block 14 to push the squeezing block 15 to move, and then drive the two sealing rings 16 to get closer. The magnet 18 is used to assist in clamping the edge of the sealing ring 7 and the pipeline, so as to prevent other gases from entering the sealing ring 7, and ensure that no other gases enter the sealing ring 7 during the test, thereby ensuring the purity of the fuel gas and the accuracy of the data during the detection.
[0025] The working principle and use process of the utility model are as follows: when the first clamping ring 4 and the second clamping ring 6 clamp the connection of the pipeline and then fix it with the clamping bolt 11, after fixing, if gas leakage occurs in the area, the gas will enter the connecting pipe 3 through the drainage groove 8 and then be transmitted to the sensor in the control box 1, and then the leakage value will be displayed. While clamping and fixing, the pipeline will squeeze the moving ring 9 to move. The moving ring 9 can squeeze the airbag 12 when moving, and the airbag 12 drives the sliding rod 13 to move.
