Abstract

The invention provides a seabed pipeline simulation impact test system. The test system comprises a door-shaped support frame across an earth pond, a pipeline for simulating a seabed pipeline is arranged in the earth pond, a crossbeam of the door-shaped support frame is provided with a moving seat capable of performing translation along the crossbeam, a slide guide rail is vertically arranged below the crossbeam from the moving seat in an extending manner, the moving seat is provided with a lifting winch, the lower end of the lifting winch is suspended with a simulation impact object arranged along the slide guide rail in a sliding manner, the seabed pipeline is positioned right below the crossbeam of the door-shaped support frame, one end of the seabed pipeline is connected with a fixed support frame, the other end of the seabed pipeline is connected with a loading axial load device and a translation support frame in sequence, the seabed pipeline is a sealed pipe body, and one end of the seabed pipeline is connected with a loading internal pressure device. According to the simulation test system, impact test simulation of falling objects for the pipeline can be realized in the conditions of pre-added axial load and internal pressure of the pipeline, and simulation impact tests of the pipelines in the conditions of different lengths, embedding depths, impact positions, and impact contact surface shapes can be conducted.

Description

technical field [0001] The invention relates to an impact test device for a submarine pipeline in marine engineering technology, in particular to a simulated impact test system for a submarine pipeline used for simulating the impact of the submarine pipeline under various conditions. Background technique [0002] After entering the middle of the 20th century, the problem of shortage of oil resources has become increasingly prominent in the modern society with rapid economic development. With the increasing scope of ocean mining, deep sea oil development has become an important frontier of the oil industry. At the same time, my country's shipping industry and fishery have made great progress. In terms of ship transportation, with the increasing number of coastal ports and berths, the tonnage of ships is getting larger and larger, and accidental anchoring operations are becoming more and more frequent; in terms of fishery production, the fishery operation area is becoming mor...
