Description

Technical Field

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

[0002] Gas pipelines are specialized facilities for transporting natural gas. Their core function is to safely and stably deliver natural gas, manufactured gas, and other similar gases from gas sources (such as gas fields and gas plants) to end users. Through a pipeline network system of different pressure levels (high pressure, medium pressure, and low pressure), and after pressure regulation by facilities such as gate stations and pressure regulating stations, they are distributed to industrial enterprises, commercial establishments, and residential households. They provide energy for production, commercial operations, and daily life, meeting needs for heating, cooking, and power. They are an important component of the urban energy supply system, ensuring efficient gas transmission and safe end-user use.

[0003] The existing Chinese utility model patent with publication number CN219346250U discloses a gas pipeline leak detection device. This device includes a housing, an assembly cylinder installed inside the housing, and an installation plate movably connected to the assembly cylinder via an adjustment component. A fixing block is connected to the bottom of the installation plate, and a detector is installed at the bottom of the fixing block. A spring is provided on the outside of the detector, connecting it to the installation plate. A telescopic rod is mounted on the top side of the housing, and a moving wheel and a support column are respectively provided on the bottom of the housing. In use, the telescopic rod and the moving wheel at the bottom of the housing allow for easy movement of the detection device to the detection position. By rotating the adjustment handle and pressing the assembly plate, the detector connected to the installation plate can be moved up and down to adjust its position, facilitating its extension for detection. When not in use, the detector can be stored and protected.

[0004] Currently used gas pipeline leak detection devices still have the following problems:

[0005] Currently, gas pipeline leak detection mainly relies on regular on-site inspections by personnel. However, if no one is home during the inspection process, the inspectors cannot enter the house to conduct a comprehensive and detailed inspection of the gas pipelines. This means that potential safety hazards in the gas pipelines of these households cannot be detected in a timely manner. Gas pipelines that are left unattended for extended periods can lead to serious consequences if a leak occurs. Therefore, there is an urgent need for a new technology or equipment to solve the problem of gas pipeline leaks that cannot be detected when no one is home, and to effectively ensure the safe operation of gas pipelines. Utility Model Content

[0006] The purpose of this invention is to provide a gas pipeline leak detection device to solve the problem mentioned in the background art that gas pipeline leaks cannot be detected normally when no one is at home.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a gas pipeline leak detection device, including a sealing ring mechanism, a screw, a handle device, a pressure nozzle, and a connecting pipe. The screw is installed on one side of the surface of the sealing ring mechanism, and the handle devices are provided on both sides of the sealing ring mechanism. The bottom of the sealing ring mechanism is welded to the pressure nozzle, and the bottom of the pressure nozzle is interconnected with the connecting pipe. A movable shaft is movably connected to one side of the handle device, and a side clamp is movably connected to one side of the movable shaft.

[0009] The pressure nozzle has a sleeve welded in the middle, and a side column is installed laterally on one side of the sleeve, with a valve installed at one end of the side column.

[0010] Preferably, the sealing ring mechanism has a circular groove at its midpoint, and a telescopic ring is movably connected to the edge of the circular groove. The telescopic ring is connected to the edge of the midpoint of the sealing ring mechanism. Movable rings are movably connected to both sides of the sealing ring mechanism, and magnetic suction surfaces for fixed assembly of the equipment are provided on both sides of the telescopic ring.

[0011] Preferably, the handle device is movably connected to the side clamp via a movable shaft, and the side clamp is fixedly installed on the side of the sealing ring mechanism, and a connecting plate is connected between the two sets of handle devices.

[0012] Preferably, a screw is installed at the midpoint edge of the movable shaft, and the screw at the edge of the movable shaft is located at the edge of the magnetic surface, and the movable shaft is assembled to the side of the sealing ring mechanism by the screw.

[0013] Preferably, the bottom end of the pressure nozzle is connected to a connecting screw, and the pressure nozzle is interconnected with a connecting pipe through the connecting screw.

[0014] Preferably, one side of the handle device is close to the side of the sealing ring mechanism, and the midpoint of the sealing ring mechanism and the midpoint of the movable shaft are on the same horizontal line.

[0015] Preferably, the sealing ring mechanism is clamped at the connection of the gas pipeline, and the pressure nozzle is connected to the pressure gauge through a connecting pipe.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. When the gas pipeline leak detection device is in use, the sealing ring mechanism can be adjusted to different sizes of opening through the movable shaft and handle device, so that the sealing ring mechanism clamps the gas pipeline externally to realize gas leak detection. There is no need for manual point-by-point inspection, which reduces the number of times people directly come into contact with the risk environment. In addition, when users are not at home, outdoor pipeline sealing detection can be completed in manual detection mode, which solves the problem of the limitations of manual gas pipeline leak detection.

[0018] 2. When the gas pipeline leak detection device is in use, the telescopic ring mechanism can adjust the diameter of the middle of the sealing ring mechanism when clamping the gas pipeline, so that the sealing ring mechanism can adapt to gas pipelines of different specifications. It can flexibly deal with the detection of gas pipelines of different thicknesses, meet the pipeline detection needs in different scenarios, and improve the application range of the detection equipment.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] Please see Figures 1-4 A gas pipeline leak detection device includes a sealing ring mechanism 1, a screw 2, a handle device 3, a pressure nozzle 4, and a connecting pipe 5. The sealing ring mechanism 1 has a circular groove at its midpoint, and a telescopic ring 11 is movably connected to the edge of the circular groove. The telescopic ring 11 is connected to the edge of the midpoint of the sealing ring mechanism 1. Movable rings 12 are movably connected to both sides of the sealing ring mechanism 1, and magnetic suction surfaces 13 for fixed assembly of the device are provided on both sides of the telescopic ring 11.

[0029] In this embodiment, a screw 2 is installed at the midpoint edge of the movable shaft 32, and the screw 2 at the edge of the movable shaft 32 is located at the edge of the magnetic surface 13. The movable shaft 32 is assembled to the side of the sealing ring mechanism 1 by the screw 2.

[0030] This utility model discloses a gas pipeline leak detection device. The sealing ring mechanism 1 clamps the gas pipeline through the circular groove at the midpoint. One side of the telescopic ring 11 has an elastic support function. It can be fully opened when the gas pipeline does not touch the telescopic ring 11. If the gas pipeline touches one side of the telescopic ring 11, the telescopic ring 11 uses its elastic function to make one side touch the surface of the gas pipeline. The sealing ring mechanism 1 can contract according to the thickness of the gas pipeline, so that the sealing ring mechanism 1 can firmly clamp the outside of the gas pipeline for sealing detection. The movable ring 12 allows the sealing ring mechanism 1 to extend to both sides to form a complete circular clamp. The magnetic surface 13 uses the principle of magnetism to magnetically attract the movable shaft 32, assisting the movable shaft 32 to be fixedly installed on one side.

[0031] For details, please refer to the following: Figure 2 As shown, screw 2 is installed on one side of the surface of sealing ring mechanism 1, and handle device 3 is provided on both sides of sealing ring mechanism 1. The bottom of sealing ring mechanism 1 is welded to pressure nozzle 4, and the bottom of pressure nozzle 4 is interconnected with connecting pipe 5. A movable shaft 32 is movably connected to one side of handle device 3, and a side clamp 33 is movably connected to one side of movable shaft 32.

[0032] In this embodiment, the handle device 3 is movably connected to the side clamp 33 via the movable shaft 32, and the side clamp 33 is fixedly installed on the side of the sealing ring mechanism 1. A connecting plate 31 is connected between the two sets of handle devices 3. One side of the handle device 3 is close to the side of the sealing ring mechanism 1, and the midpoint of the sealing ring mechanism 1 and the midpoint of the movable shaft 32 are on the same horizontal line.

[0033] The gas pipeline leak detection device of this utility model has a side clamp 33 installed on one side of the movable ring 12. The movable ring 12 has an elastic support function and can adjust the opening of the sealing ring mechanism 1 according to the opening size of the side clamp 33. The side clamp 33 is connected to the handle device 3 through the movable shaft 32. The opening size of the side clamp 33 is adjusted according to the handle device 3 so that the sealing ring mechanism 1 can be firmly clamped on the outside of the gas pipeline to perform gas pipeline sealing detection.

[0034] For details, please refer to the following: Figure 3 As shown, the bottom of the sealing ring mechanism 1 is welded to the pressure nozzle 4. A sleeve 41 is welded in the middle of the pressure nozzle 4, and a side column tube 42 is installed laterally on one side of the sleeve 41. A valve 43 is installed at one end of the side column tube 42.

[0035] In this embodiment, the bottom end of the pressure nozzle 4 is connected to a connecting screw 44, and the pressure nozzle 4 is interconnected with the connecting pipe 5 through the connecting screw 44. The sealing ring mechanism 1 is clamped at the connection of the gas pipeline, and the pressure nozzle 4 is connected to the pressure gauge through the connecting pipe 5.

[0036] This utility model discloses a gas pipeline leak detection device. The pressure nozzle 4 and the connecting pipe 5 are interconnected. The outdoor gas pipeline is shut off, the flange is removed, and the sealing ring mechanism 1 is clamped on the outside of the pipeline. The gas pipeline can be sealed by connecting the pressure nozzle 4, the pressure gauge, and the gas pressure device. The pressure decay method is used for detection. After applying a certain pressure, if the pressure gauge reading drops, it indicates a leak. If there is no drop, it indicates that there is no leak in the pipeline. The valve 43 can open or close the pressure nozzle 4 to control whether gas enters the device.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
