[0002] At present, natural gas projects are often built with natural gas pipelines. Natural gas pipelines are pipelines that transport natural gas, including associated gas produced by oil fields, from mining sites or processing plants to urban gas distribution centers or industrial enterprise users. Using natural gas pipelines to transport natural gas is a way to transport natural gas in large quantities on land. Natural gas pipelines account for about half of the world's total pipeline length.

[0003] However, the current urban gas engineering safety protection devices are often installed and protected by simple upper and lower clamps and protective cotton sleeves during installation. Their functions are relatively simple. Since they are all fixed installations, when the installation components are hit, they are easily squeezed and deformed between the pipelines, causing deformation and damage to the gas pipelines, which is not conducive to better use of the pipelines.

The protection component 4 is arranged on the top of the pipeline buffer 2. The top of the connecting rod 24 contacts with the mounting frame 41. The protection component 4 comprises a mounting frame 41, a limit frame 42, a slide groove 43, a connecting block 44, a moving block 45, a spring three 46, a spring four 47, a through groove 48, an opening groove 49, a limit rod 40 and a limit slider 411. The top of the bottom wall of the mounting frame 41 is provided with an opening groove 49. The limit slider 411 is fixedly mounted on the limit frame 42. At the bottom, a limit slider 411 is movably installed inside the open groove 49, a slide groove 43 is opened inside the limit frame 42, and the moving block 45 is slidably installed in the slide groove 43. The outer walls on both sides of the moving block 45 are respectively fixedly connected to one end of the spring three 46 on both sides, and the bottom end of the connecting block 44 is fixedly connected to the moving block 45. A through groove 48 is opened inside the side wall of the installation frame 41, one end of the limit rod 40 is fixedly connected to the connecting block 44, and the other end of the limit rod 40 is movably inserted into the inside of the through groove 48, one end of the spring four 47 is fixedly connected to the inner wall of the through groove 48, and the other end of the spring four 47 is movably connected to the outer wall of the limit rod 40, and the installation component 3 is fixedly installed on the top of the connecting block 44.

[0026] Specifically, by providing the protective component 4, when the side of the installation frame 41 is hit, its moving block 45 will make a corresponding slide in the slide groove 43, thereby avoiding extrusion and deformation between the installation frame 41 and the pipeline, thereby providing a certain protection for the pipeline. At the same time, when the front and back of the installation frame 41 are hit, its limiting rod 40 and limiting slider 411 will slide in the through groove 48 and the opening groove 49 respectively, so that when relative displacement occurs between the installation frame 41 and the pipeline, the pipeline is not affected, which is conducive to better protection of the pipeline. Under the action of spring three 46 and spring four 47, the moving block 45 and the limiting rod 40 will be adaptively reset, so that the protective component 4 returns to its original position, which is convenient for its reuse. It is not easy for the pipeline to be squeezed and deformed between the installation frame 41 and the pipeline when it is hit, which is conducive to extending the service life of the pipeline.

[0027] In this embodiment, the pipeline buffer 2 includes a mounting sleeve 21, a limit plate 22, a limit groove 23, a connecting rod 24, a movable plate 25, a spring 26, a damping spring 27 and a buffer damper 28.

[0028] Specifically, when in use, the limit plate 22 can be snapped into a suitable limit groove 23 according to the installation height of the pipeline, so that the device can be suitable for installation in pipelines of different heights. When external vibrations occur or pressure shocks and similar water hammer phenomena occur in the pipeline system, the pipeline and connectors can be protected, which is beneficial for buffering their vibrations. At the same time, it can also eliminate pipeline vibrations, reduce pressure pulsations, reduce flow fluctuations, and protect downstream instruments and equipment. Installing it at the front end of the pump can increase the volumetric efficiency of the pump and improve the output power.

[0029] The mounting assembly 3 includes a base 31, a lower clamp 32, an auxiliary sleeve 33, a mounting pipe 34, an upper clamp 35, a spring 2 36, a reinforcing rod 37 and a mounting bolt 38. The base 31 is fixedly mounted on the top of the connecting block 44, the lower clamp 32 is fixedly mounted on the inner wall of the base 31, the upper clamp 35 is arranged on the top of the lower clamp 32, the upper clamp 35 and the lower clamp 32 are fixed by mounting bolts 38, the inner walls of the upper clamp 35 and the lower clamp 32 are fixedly mounted with a spring 2 36, the other end of the spring 2 36 is fixedly connected to the auxiliary sleeve 33, the mounting pipe 34 is arranged inside the auxiliary sleeve 33, the reinforcing rod 37 is embedded in the horizontal plates of the upper clamp 35 and the lower clamp 32, and connecting bolts are arranged between the two groups of reinforcing rods 37 for fixing.

[0030] Specifically, when in use, the pipe is installed inside the bottom auxiliary sleeve 33, and the upper clamp 35 is installed above the lower clamp 32, so that the pipe can be fixed. The spring 36 is used so that the device can be applied to pipes of different diameters, making the device more applicable and avoiding hard contact between the pipe and the clamp, thereby preventing extrusion deformation during fixation. The reinforcement rod 37 is used for auxiliary fixation to make the connection between the upper and lower clamps 32 more stable.

[0031] In summary, compared with the prior art, the urban gas engineering safety protection device has at least the following beneficial effects: by providing the protection component 4, when the side of the installation frame 41 is hit, the moving block 45 will make a corresponding slide in the slide groove 43, thereby avoiding the squeezing and deformation between the installation frame 41 and the pipeline, thereby playing a certain protective role for the pipeline, and at the same time, when the front and back of the installation frame 41 are hit, the limiting rod 40 and the limiting slider 411 will slide in the through groove 48 and the opening groove 49 respectively, so that when the installation frame 41 and the pipeline are relatively displaced, the pipeline is not affected, which is conducive to better protection of the pipeline, and under the action of spring three 46 and spring four 47, the moving block 45 and the limiting rod 40 will be adaptively reset, so that the protection component 4 returns to its original position, which is convenient for its reuse, and it is not easy for the pipeline to be squeezed and deformed between the installation frame 41 and the pipeline when it is hit, which is conducive to extending the service life of the pipeline.
