Description

Technical Field

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

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane, and biogenic gas, etc.).

[0003] Since natural gas is a combustible gas, in order to ensure the safety of natural gas transportation during actual pipeline transportation, corresponding leakage detection devices are generally equipped for continuous monitoring.

[0004] The aforementioned leak detection device generally consists of an instrument body, a display screen, and a detection sensor. It mainly detects the concentration of natural gas through the detection sensor, then analyzes and processes the data through the instrument body, and finally displays the results on the display screen. Since there is no protective mechanism on the display screen, it can be damaged under external force. Therefore, we propose a natural gas pipeline leakage detection device. Utility Model Content

[0005] The purpose of this invention is to provide a natural gas pipeline leakage detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a natural gas pipeline leakage detection device, comprising: Leak detector; The detection sensor is located at the bottom of the gas leak detector and is used to detect natural gas. The display screen is fixedly connected to the outer surface of the leak detector; A protective mechanism is provided on one side of the display screen, and the protective components are used to protect the display screen; An elastic mechanism is connected to one side of the protective mechanism and is used to cushion the protective mechanism.

[0009] Preferably, the elastic rod assembly includes: A movable rod, which is inserted into the through hole and one end of the movable rod is fixedly connected to the protective mechanism; A limiting nut, which is threadedly connected to the middle of the movable rod; A buffer spring is sleeved on the end of the movable rod.

[0013] The technical effects and advantages of this utility model are as follows: This invention installs an elastic mechanism on the side of the leak detector before assembling a protective mechanism. When an external force is about to contact the display screen, the force will first contact the protective mechanism, which then protects the display screen. Simultaneously, the protective mechanism moves backward, squeezing the elastic mechanism to buffer the external force, further protecting the display screen. This design uses the protective mechanism to protect the display screen, preventing direct contact with external forces, and then works in conjunction with the elastic mechanism to buffer the external force, thus providing excellent protection for the display screen. Furthermore, the transparent circular block in the protective mechanism and the buffer spring in the elastic mechanism are easy to replace. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] This utility model provides, for example Figures 1-3 The image shows a natural gas pipeline leakage detection device.

[0019] Example 1: Includes a gas leak detector 1, a detection sensor 2 located at the bottom of the gas leak detector 1 for detecting natural gas, a display screen 3 fixedly connected to the outer surface of the gas leak detector 1, a protective mechanism located on one side of the display screen 3 for protecting the display screen 3, and an elastic mechanism connected to one side of the protective mechanism for cushioning the protective mechanism; by installing the elastic mechanism on the side of the gas leak detector 1 and then assembling the protective mechanism, when an external force comes into contact with the display screen 3, the external force will first contact the protective mechanism, using the protective mechanism to protect the display screen 3, while the protective mechanism will also move backward, thereby squeezing the elastic mechanism. The protective mechanism uses an elastic mechanism to buffer external forces, thereby further protecting the display screen 3. This design uses a protective mechanism to protect the display screen 3, preventing external forces from directly contacting the display screen 3. Then, in conjunction with the elastic mechanism, the protective mechanism is buffered, thus buffering external forces and providing good protection for the display screen 3. In actual use, the natural gas concentration is detected by the detection sensor 2, and the natural gas concentration data in the environment is transmitted to the leak detector 1. The leak detector 1 then displays the natural gas concentration data on the display screen 3, thereby forming a continuous detection of whether a natural gas leak has occurred in the pipeline.

[0020] Furthermore, the elastic mechanism includes a fixed frame assembly 6, which is fixedly connected to the side of the leak detector 1. An elastic rod assembly 7 is inserted into the middle of the fixed frame assembly 6, and one end of the elastic rod assembly 7 is fixedly connected to the protective mechanism. By moving the elastic rod assembly 7 along the fixed frame assembly 6, the elastic rod assembly 7 can buffer the protective mechanism, thereby further improving the protective effect on the display screen 3.

[0021] Furthermore, the fixed frame assembly 6 includes a frame body 601, which is fixedly connected to the outer surface of the middle part of the leak detector 1, and through holes 602 are opened at both ends of the frame body 601; the frame body 601 is fixed to the outside of the leak detector 1 by welding, and the through holes 602 are for facilitating the movement of the elastic rod assembly 7.

[0022] Furthermore, the elastic rod assembly 7 includes a movable rod 701, which is inserted into the through hole 602. One end of the movable rod 701 is fixedly connected to the protective mechanism. A limiting nut 702 is threadedly connected to the middle of the movable rod 701, and a buffer spring 703 is sleeved on the end of the movable rod 701. When an external force contacts the protective mechanism, the protective mechanism drives the movable rod 701 to move along the through hole 602, thereby causing the limiting nut 702 to compress the buffer spring 703. The buffer spring 703 is used to buffer the impact force of the external force. When the external force is removed, the buffer spring 703 returns to its original deformation, thereby driving the movable rod 701 to reset. Later, the limiting nut 702 can be rotated to separate the limiting nut 702 from the movable rod 701, thereby removing the movable rod 701 from the through hole 602 and replacing the buffer spring 703.

[0023] Furthermore, the protective mechanism includes a connecting ring assembly 4, which is fixedly connected to one end of the elastic rod assembly 7, and a transparent component 5 is disposed inside the connecting ring assembly 4; by utilizing the cooperation of the connecting ring assembly 4 and the transparent component 5, the display screen 3 is covered for protection, thereby preventing external forces from directly contacting the display screen 3.

[0024] Furthermore, the connecting ring assembly 4 includes a fixing ring 401, which is fixedly connected to the end face of the elastic rod assembly 7. The fixing ring 401 has an annular groove 402 in the middle. The compression ring 403 is threadedly connected to the inside of the annular groove 402. The transparent assembly 5 includes an outer ring 501 located inside the annular groove 402 and a transparent round block 502 fixedly connected to the inside of the outer ring 501. The transparent round block 502 facilitates the observation of data on the display screen 3 later. When the transparent round block 502 is damaged, the compression ring 403 can be rotated to remove the compression ring 403 from the annular groove 402, and then the transparent round block 502 can be removed from the annular groove 402 for replacement. Then, the compression ring 403 is reversed to screw the compression ring 403 into the annular groove 402, thereby compressing the outer ring 501 and fixing the transparent assembly 5.

[0025] Example 2: Example 2 further discloses that the transparent circular block 502 is made of transparent glass or transparent plastic, which makes it convenient to observe the data displayed on the display screen 3 by using the transparent circular block 502 made of transparent material.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
