Description

Technical Field

[0001] The utility model belongs to the field of natural gas warning, and particularly relates to a warning device for gas pipeline laying construction. Background Art

[0002] The warning device for gas pipeline laying construction mainly involves the importance and fragility of gas pipelines, the limitations of traditional warning methods and the need for technological innovation. By adopting warning devices with precise positioning, good warning effects, strong anti-destruction and weather resistance, the safety and construction efficiency of gas pipelines can be significantly improved. The warning device for gas pipeline laying construction can significantly reduce the incidence of gas pipeline damage and safety accidents. These devices can also improve construction efficiency and reduce construction delays and cost increases caused by mis-digging of pipelines.

[0003] The prior art has specially developed some warning devices for gas pipeline laying construction to improve the safety when installing gas pipelines. For example, the Chinese patent with publication number "CN221076199U" announced "a gas pipeline warning device" that passes through the base through a column and is connected to the base with a limit position. The base is arranged on the bottom side of the column, so that the center of gravity of the gas pipeline warning device is moved downward, and after the base is buried in the ground, it is difficult for the column to tilt or fall over; an axial channel is arranged inside the column that passes through the bottom. Since the column passes through the base, the bottom end of the column is located below the base after burial. If a natural gas leak occurs in the gas pipeline, the leaked natural gas will escape into the channel. The operator can detect the natural gas concentration in the channel from the detection port on the column through the detection instrument, so as to determine whether the buried gas pipeline has a leak, avoid excavating the ground for natural gas leak detection, reduce the work intensity, optimize the work process, and shorten the detection time.

[0004] Since the base can only be buried in the ground and cannot fit tightly against the gas pipeline, it will lead to inaccurate testing of gas leaks and can easily mislead detection personnel. The warning device protruding outside cannot enhance safety awareness and can only serve as a reminder to people around. It is not easy for staff to find gas leaks, which will reduce safety. Although the structure is simple and reduces costs, it will increase the risk and cause irreversible damage to the surrounding areas. Utility Model Content

[0016] Second, when the buzzer sounds, the warning light installed on the top of the warning box will flash at the same time, so that the location of the gas leak can be found even at night. Since the gas leak sensor, buzzer and alarm light are electrically connected to the solar panel, this can effectively save power outdoors and save electricity costs. The staff can also use the detection instrument to detect the concentration of the gas leak through the detection port to implement the corresponding solution, which is conducive to enhancing safety.

A warning box 3 is fixedly installed on one end of the connecting column 5 away from the fixing pile 6, and a gas leakage sensor 11 is fixedly installed inside the warning box 3. A warning light 19 is fixedly installed on one end of the warning box 3 away from the connecting column 5, and solar panels 20 are fixedly installed on both sides of the warning light 19 at one end of the warning box 3 away from the connecting column 5.

[0025] refer to Figures 2 to 3 , an external thread 17 is integrally formed at one end of the connecting column 5 away from the warning box 3, and an internal thread 18 is provided inside the fixing pile 6, and the connecting column 5 can be fixed by connecting the external thread 17 to the internal thread 18. The internal thread 18 and the external thread 17 allow a channel 12 to be provided inside the connecting column 5, so that the leaked gas can enter the warning box 3 through the channel 12 to remind the surrounding personnel. When the connecting column 5 is removed, transportation space can be saved, which is convenient for installation and improves portability and usability. A channel 12 is provided inside the connecting column 5, and a circular opening 13 is provided inside the sealing box 7 at the position of the fixing pile 6, and the circular opening 13 is connected to the channel 12 inside the connecting column 5. Since the circular opening 13 is provided inside the sealing box 7, the leaked gas gathers in the sealing box and will be drained into the channel 12 by the circular opening 13, and then flows into the warning box 3. In this way, the gas leakage can be detected by the gas leak sensor 11, and the surrounding personnel can be reminded in time.
