Problems solved by technology

As the use of natural gas becomes more common, the demand for natural gas pipelines is also increasing. Existing pipelines are usually directly exposed outdoors, which are vulnerable to external impacts and affect the safety of gas transmission. Therefore, a natural gas pipeline protection device is proposed

Abstract

The invention relates to the technical field of protecting, in particular to a natural gas pipeline protecting device. Multiple sets of hinge bases are connected to the lower end of a first protecting sleeve and the lower end of a second protecting sleeve. Multiple sets of connecting bases are installed at the upper end of the first protecting sleeve and the upper end of the second protecting sleeve correspondingly. The multiple sets of connecting bases are fastened through pretightening bolts. Clamping mechanisms are further installed on the portions, between the two sets of pretightening bolts, of the connecting bases. Multiple reset springs are connected to the inner side of the first protecting sleeve and the inner side of the second protecting sleeve correspondingly. Clamping plates are connected to the ends of the reset springs correspondingly. Multiple T-shaped clamping grooves are formed in the surfaces of the clamping plates. T-shaped clamping blocks are clamped into the multiple T-shaped clamping grooves correspondingly. A connecting plate is connected to the outside of each T-shaped clamping block. A heat preserving layer is arranged on the inner side of each connecting plate. The natural gas pipeline protecting device is convenient to install, good in protecting effect, resistant to impact and high in practicality, safety of natural gas pipeline conveying is improved greatly, the working efficiency is improved effectively, and waste of labor force is reduced.

Description

technical field [0001] The invention relates to the technical field of protection, in particular to a natural gas pipeline protection device. Background technique [0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission pipelines. The use of natural gas pipelines to transport natural gas is the only way to transport large quantities of natural gas on land. As the use of natural gas becomes more common, the demand for natural gas pipelines is also increasing. Existing pipelines are usually directly exposed outdoors, which are vulnerable to external impacts and affect the safety of gas transmission. Therefore, natural gas pipeline protection devices are proposed. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior a...
