Problems solved by technology
[0002] When natural gas is transported, it is transported through pipelines. When natural gas is transported, the required strength of the pipeline is higher. Otherwise, if there is a crack in the pipeline, a large amount of natural gas will leak out, causing serious safety accidents and affecting the normal gas consumption of users. The current technology In the natural gas pipeline, the gas leakage alarm device will be installed on the natural gas pipeline. This method can only realize the alarm, and cannot detect and seal it at the first time. Moreover, the general natural gas pipeline is set in a static state. Corrosion and acidification of rainwater lead to reduction of pipeline strength

Embodiment Construction
[0019] Such as figure 1 As shown, the natural gas transmission pipeline includes a pipeline main body 1, and more than one set of rotation detection components are arranged on the pipeline main body 1, and the rotation detection components are installed on two bearings 2, and the pipeline main body 1 is fixed through the bearing hole of the bearing, and rotates The detection components are equidistantly arranged on the pipeline main body 1;
[0020] Each rotation detection assembly includes a hollow rotating tube 4, an installation cavity 3 is formed between the hollow rotating tube 4 and the outer wall of the pipeline main body 1, a sealing assembly is installed in the installation cavity 3, and the outer wall of the hollow rotating tube 4 rotates around the hollow There is more than one choke vane on one circle of the tube. The hollow rotating tube 4 is fixedly installed on the outside of the two bearings 2, and rotates 360 degrees along the bearings 2. Since the hollow rota...

The invention discloses a natural gas conveying pipeline. The natural gas conveying pipeline comprises a pipeline body, more than one set of rotary detection assemblies are arranged on the pipeline body, each rotary detection assembly is arranged on two bearings, the pipeline body penetrates through bearing holes of the bearings to be fixed, the rotary detection assemblies are arranged on the pipeline body at equal intervals, each rotary detection assembly comprises a hollow rotating pipe, a mounting cavity is formed between each hollow rotating pipe and the outer wall of the pipeline body, asealing assembly is arranged in each mounting cavity, more than one flow blocking blade is arranged on the positions, surrounding each hollow rotating pipe for one circle, of the outer wall of the corresponding hollow rotating pipe, and each hollow rotating pipe is fixedly arranged outside the two bearings and rotates by 360 degrees along the bearings. According to the natural gas conveying pipeline, the whole rotary detection assemblies are driven by natural wind power for detection, and sealing is carried out at the first time after gas leakage is detected, so that more time can be brought to the first-aid repair, the safety can be improved, and economic loss can be reduced.
Description
technical field [0001] The invention relates to the field of natural gas transportation, in particular to a natural gas transportation pipeline. Background technique [0002] When natural gas is transported, it is transported through pipelines. When natural gas is transported, the required strength of the pipeline is higher. Otherwise, if there is a crack in the pipeline, a large amount of natural gas will leak out, causing serious safety accidents and affecting the normal gas consumption of users. The current technology In the natural gas pipeline, the gas leakage alarm device will be installed on the natural gas pipeline. This method can only realize the alarm, and cannot detect and seal it at the first time. Moreover, the general natural gas pipeline is set in a static state. Corrosion and acidification of rainwater lead to reduction of pipeline strength. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a natu...
