Abstract

The invention discloses a pipeline fixed installation system based on energy recovery. The pipeline is fixed on a heat insulation installation plate through a heat insulation fixing component, and the heat insulation installation plate is fixed above the permafrost layer through antifreeze pulling support legs. The heat insulation fixing assembly includes two positioning installation parts up and down, and the two positioning installation parts are butted to form a circular channel for the crude oil pipeline to pass through. Each positioning installation part includes a shell plate that forms a sealed chamber inside; the fixed installation An energy recovery component is arranged on the upper part, and the energy recovery component includes a semiconductor power generation sheet that is fixed on the bottom of the shell plate and can be closely attached to the outer wall of the pipeline. The top of the semiconductor power generation sheet is fixed to the The cold plate on the top of the shell plate is connected, and the semiconductor power generation sheet is electrically connected with the battery in the data acquisition protection box. The invention is environment-friendly and has high fixing stability.

Description

technical field [0001] The invention relates to the technical field of frozen soil, in particular to an energy recovery-based pipeline fixed installation system. Background technique [0002] Permafrost refers to soil or rocks that have a temperature of 0°C or below, contain ice, and have been frozen for more than two years. Its area accounts for about 1 / 4 of the land area of ​​the northern hemisphere. There are abundant oil and gas resources in these vast areas. With the further exploitation and utilization of global oil and gas resources, there are more and more oil and gas pipeline projects in permafrost regions. However, buried pipeline projects are affected by multiple influences of oil temperature and external environment, and pipeline projects built in permafrost regions will face various permafrost disasters. When high-temperature crude oil pipelines are buried in permafrost areas, the permafrost at the lower part of the pipelines will melt, and uneven thawing will...
