Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a gas pipeline transmission leakage detection device. Background Art

[0002] Natural gas refers to a type of combustible gas that exists in nature. It is a fossil fuel, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. Natural gas is stored in underground porous rock formations. It is a high-quality fuel and chemical raw material. The main use of natural gas is as fuel. It can be used to produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of a mixture of gaseous low-molecular hydrocarbons and non-hydrocarbon gases.

[0003] With the development of society, the demand for natural gas has increased. Most of the natural gas is transported by pipeline. However, when transported by pipeline, there is a problem of natural gas leakage. Usually, a pressure gauge is installed between each section of the natural gas pipeline to detect the pressure value of the natural gas in the pipeline. If a natural gas leaks, the leaking section of the pipeline can be quickly located. However, the length of each section of the pipeline is long. If the leakage port of the natural gas pipeline is small, it will be troublesome to manually determine the leakage location, which is inefficient. Therefore, a natural gas pipeline leakage detection device is needed to solve the above problem. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a gas leakage detection device for natural gas pipelines. The technical solution adopted is as follows: the device includes a natural gas pipeline, a mounting ring, a rubber ring, and a natural gas detector. The mounting ring is sleeved on the natural gas pipeline, the natural gas detector is arranged on the mounting ring, and the detection head of the natural gas detector is arranged on the inner side surface of the mounting ring. The mounting ring includes an upper half ring and a lower half ring. The left ends of the upper half ring and the lower half ring are hinged by a hinge, and the right ends of the upper half ring and the lower half ring are connected by a lock buckle. The rubber ring is arranged on the front and rear sides of the inner side surface of the mounting ring, and the inner side surface of the rubber ring contacts the outer side surface of the natural gas pipeline. The mounting ring is sleeved on the natural gas pipeline, so that a cavity is formed between the natural gas pipeline and the mounting ring. Leaked natural gas can be stored in the cavity and detected by the natural gas detector, thereby detecting which part of the natural gas pipeline is leaking. The rubber ring can seal the cavity between the natural gas pipeline and the mounting ring to prevent natural gas leakage and inaccurate detection. The lock buckle facilitates separation of the upper and lower half rings, thereby clamping the mounting ring to the natural gas pipeline.

[0005] As a preferred technical solution for a natural gas pipeline leakage detection device of the present invention, rollers are provided on the inner sides of the upper half ring and the lower half ring. The rollers can support the mounting ring on the natural gas pipeline and facilitate the movement of the mounting ring on the natural gas pipeline, thereby performing detection at different positions of the natural gas pipeline.

[0006] As a preferred technical solution for a natural gas pipeline leakage detection device of the present invention, mounting grooves are fixedly installed on the front and rear sides of the inner side surfaces of the upper half ring and the lower half ring. One end of the rubber ring is open, and the rubber ring is tightly inserted into the mounting groove. The plug-in installation method of the rubber ring facilitates the replacement of worn and aged rubber rings.

[0007] As a preferred technical solution of a natural gas pipeline leakage detection device of the present invention, handles are fixedly installed on the sides of the upper and lower half rings, and the handles are used to facilitate the movement of the upper and lower half rings.

[0008] As a preferred technical solution for a natural gas pipeline leakage detection device of the present invention, the upper half ring and the lower half ring are made of metal. The upper half ring and the lower half ring made of metal can effectively prevent them from being squeezed and deformed by gas after long-term use, resulting in loose contact of the rubber ring.

[0009] As a preferred technical solution of a natural gas pipeline leakage detection device of the present invention, the natural gas detector is provided with a buzzer, which can remind users of the leakage location.

[0010] The beneficial effects of the utility model are as follows: the utility model is connected to the natural gas pipeline by the installation ring, so that a cavity is formed between the natural gas pipeline and the installation ring, so that leaked natural gas can exist in the cavity and be detected by the natural gas detector, thereby detecting which part of the natural gas pipeline is leaking. The rubber ring can seal the cavity between the natural gas pipeline and the installation ring, preventing natural gas leakage and inaccurate detection. The upper half ring and the lower half ring are easy to separate by the lock buckle, so that they are clamped on the natural gas pipeline. The installation ring can be supported on the natural gas pipeline by the roller, and the installation ring can be easily moved on the natural gas pipeline, so that detection can be carried out at different positions of the natural gas pipeline. The rubber ring plug-in installation method is convenient for replacing worn and aged rubber rings. The handle can be used to push the upper half ring and the lower half ring to move. The upper half ring and the lower half ring made of metal can effectively prevent them from being squeezed and deformed by gas after long-term use, which causes the rubber ring to be loose in contact. A buzzer is set on the natural gas detector to remind users of the leakage location. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example 1

[0017] like Figures 1 to 4As shown, the utility model discloses a gas pipeline transmission leakage detection device, which adopts the technical solution of comprising a natural gas pipeline 1, a mounting ring 2, a rubber ring 3 and a natural gas detector 4. The mounting ring 2 is sleeved on the natural gas pipeline 1, the natural gas detector 4 is arranged on the mounting ring 2, and the detection head of the natural gas detector 4 is arranged on the inner side of the mounting ring 2. The natural gas detector 4 is provided with a buzzer, which can remind the user of the leakage location by setting the buzzer on the natural gas detector 4. The mounting ring 2 comprises an upper half ring 21 and a lower half ring 22. The upper half ring 21 and the lower half ring 22 are connected to each other. The left end of the half ring 22 is hinged by a hinge, and the right ends of the upper half ring 21 and the lower half ring 22 are connected by a lock buckle 201. Rollers 202 are provided on the inner sides of the upper half ring 21 and the lower half ring 22. The rollers 202 can support the mounting ring 2 on the natural gas pipeline 1, and can facilitate the movement of the mounting ring 2 on the natural gas pipeline 1, so as to perform detection at different positions of the natural gas pipeline 1. Handles 204 are fixedly installed on the sides of the upper half ring 21 and the lower half ring 22, and the handles 204 can facilitate the movement of the upper half ring 21 and the lower half ring 22. The half ring 21 and the lower half ring 22 are made of metal. The upper half ring 21 and the lower half ring 22 made of metal can effectively prevent them from being squeezed and deformed by gas after long-term use, which causes the rubber ring 3 to be loose in contact. The rubber ring 3 is arranged on the front and back sides of the inner side of the mounting ring 2, and the inner side of the rubber ring 3 contacts the outer side of the natural gas pipeline 1. The front and back sides of the inner side of the upper half ring 21 and the lower half ring 22 are fixedly installed with mounting grooves 203. One end of the rubber ring 3 is open. The rubber ring 3 is tightly inserted into the mounting groove 203. The installation method of the connection is convenient for replacing the worn and aged rubber ring 3. The installation ring 2 is sleeved on the natural gas pipeline 1, so that a cavity is formed between the natural gas pipeline 1 and the installation ring 2, so that leaked natural gas can exist in the cavity and be detected by the natural gas detector 4, thereby detecting which part of the natural gas pipeline 1 is leaking. The rubber ring 3 can seal the cavity between the natural gas pipeline 1 and the installation ring 2 to prevent natural gas leakage and inaccurate detection. The lock buckle 201 facilitates the separation of the upper half ring 21 and the lower half ring 22, so that they are clamped on the natural gas pipeline 1.

[0018] The working principle of the present invention is as follows: according to the pressure gauge between the natural gas pipelines, the leakage of the natural gas pipeline in the corresponding section is determined, the upper half ring 21 and the lower half ring 22 are sleeved on the end of the natural gas pipeline, and then the lock buckle 201 is connected. The rubber ring 3 is tightly attached to the outer wall of the natural gas pipeline. The handle 204 is grasped to push the installation ring 2. The rubber ring 3 rubs the outer wall of the natural gas pipeline, and the roller 202 moves along the outer wall of the natural gas pipeline, and stays for 2 seconds after each movement to ensure that the leaked natural gas can be filled into the cavity formed by the natural gas pipeline and the installation ring 2, so as to be detected by the natural gas detector 4. When the buzzer of the natural gas detector 4 sounds, the leakage is located in the installation ring 2. Remove the installation ring 2 to further determine the leakage location.
