Protection device used for outdoor natural gas transport pipeline

Abstract

The invention discloses a protection device used for an outdoor natural gas transport pipeline. The protection device used for the outdoor natural gas transport pipeline comprises a first support rodand a second support rod, wherein the second support rod horizontally penetrates into the first support rod; the second support rod is capable of moving in the first support rod in the vertical direction, and capable of moving in the first support rod in the horizontal direction; a second fixed element is arranged at one end of the first support rod; the second fixed element comprises a vertical plate and a connection element with a U-shaped structure; the vertical plate is connected with the tail end of the first support rod; the two ends of the connection element penetrate into the verticalplate; a first fixed element is arranged at the top of the second support rod; the first fixed element comprises a transversal plate, a top plate and a fixed rod; the bottom of the transversal plate is connected with the top of the second support rod; a first V-shaped groove is formed in the top of the transversal plate; the top plate is located at the top of the transversal plate; the fixed rod is connected with the top plate through a thread; and the fixed rod is capable of moving into the first V-shaped groove by being rotated.

Description

technical field [0001] The invention relates to the field of natural gas pipelines, in particular to a protective device for outdoor natural gas transportation pipelines. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcano gas, coal bed methane, and biologically generated gas, etc.). The definition of "natural gas" that people have used for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the formation. In natural gas geology, it usually refers to oil field gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases. Due to the extremely uneven distribution of natural gas resources in my country, it is necessary to transport the extra...

Problems solved by technology

In the installation process of natural gas pipelines, elbows are often applied. At present, when installing elbows, most of them are installed by lifting, but this method makes the elbows easy to swing in the air. It is not easy to quickly align the two ends of the elbow with the pipe, which reduces the installation efficiency of the elbow, and after the installation of the elbow is completed, the elbow cannot be supported
