Abstract

The invention discloses an oil and gas pipeline protection device. The device comprises a pipeline, a protection device body, a spring part, a rubber sheet, a plastic square box, bolts and other components; the protection device body is formed by welding supporting legs and diagonal bars on the lower portion, a concentric-square-shaped steel pipe, steel wire meshes and the like on the upper portion; the concentric-square-shaped steel pipe is welded to be in a grid shape; the steel wire meshes are welded to the upper surface and the lower surface of the concentric-square-shaped steel pipe; the plastic square box is filled with colored smoke and arranged in grids of the concentric-square-shaped steel pipe; the rubber sheet and the spring part are sequentially located on the lower portion of the concentric-square-shaped steel pipe; the pipeline protection device and the pipeline are fixed through the bolts; and when external force acts on the pipeline, the concentric-square-shaped steel pipe and the steel wire meshes counteract part of the external force, if the plastic square box is damaged, the colored smoke of the plastic square box escapes, constructors can be warned, and part of impact force can be relieved through the spring part and the rubber sheet under the plastic square box. The pipeline can be protected in a multi-layer manner, the reminding function is achieved, the application range is wide, and operability is high.

Description

technical field

[0001] The invention relates to the field of pipeline protection devices, in particular to an oil and gas pipeline protection device. Background technique

[0002] Oil and gas resources are widely used in the field of social production and life as energy resources. Due to the particularity of their resource properties, they are mostly transported by pipelines. Most of the pipelines are laid underground to reduce the possibility of damage to the pipelines. However, when some necessary construction areas around the pipelines have operational activities, the pipelines are easily damaged, causing unnecessary economic losses.

[0003] At present, most of the pipeline protection devices have complex structures, and they need to be laid at the same time as the pipeline in the early stage of pipeline construction, and the installation is difficult, and most of them lack the function of early warning. Considering that the top of the pipeline is most likely to be dama...
