Problems solved by technology

The DNV code adopts the energy method to calculate the anti-shock energy for the safety assessment of the anchoring and impact of submarine pipelines, which cannot meet the development needs of ship operations and submarine pipelines.
In the existing anti-anchoring test research device, it is still impossible to fix and adjust the impacted pipeline with multiple degrees of freedom, and it is difficult to simulate a variety of submarine pipelines laid at different angles on the seabed

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] A multi-degree-of-freedom pipeline fixing test device of the present invention such as figure 1 shown. The structure includes a pipe fixing device and a degree of freedom adjustment part.

[0025] Pipe fixture parts such as figure 2 As shown, the two pipe clamping plates 7 at both ends of the device respectively hoop the two ends of the pipe, and the bolts are tightened and fixed through the fixing screw holes 19 of the clamping plates. The pipe clamping plates 7 are all supported by the pipe bracket 18 with the rotating shaft. The pipe bracket 18 with the rotating shaft can rotate within 180 degrees around the rotating shaft at the fixing bolt 17 of the rotating shaft. Locking and fixing, so that after the two ends of the pipe form a preset angle, they are respectively fixed with the slidable brackets 21 on both sides.

[0026] The degree of free...

Abstract

The invention provides a multi-degree-of-freedom pipeline fixing test device. The device comprises two sets of pipeline fixing parts and a degree-of-freedom adjusting part, each set of pipeline fixingpart comprises a pipeline bracket (18) with a rotating shaft and a pipeline clamping plate (7) used for hooping a pipeline, the pipeline clamping plates (7) are supported by the pipeline bracket (18)with the rotating shaft, and the pipeline is clamped and fixed by the pipeline clamping plate (7) through a clamping plate fixing screw hole (19); the pipeline bracket (18) with the rotating shaft isconnected to a slidable bracket (21) through a fixing bolt (17) and can rotate around the rotating shaft at the rotating shaft fixing bolt (17), so that preset angles are formed at the two ends of the pipeline; and the degree-of-freedom adjusting part comprises a transverse adjusting part, a longitudinal adjusting part, a rotary adjusting part and a vertical adjusting part. The device is stable in structure, easy to adjust and capable of meeting impact effects such as test impact.

Description

technical field [0001] The invention relates to a test device capable of fixing pipelines with multiple degrees of freedom, capable of carrying out anchor-resistant tests of submarine pipelines and the like. Background technique [0002] my country has carried out oil exploration on land for many years, but due to the constraints of resources and environment, the development potential of the remaining stored oil and gas resources is seriously insufficient. Judging from the current development trend, China's oil and gas exploration and exploitation need to explore new growth points in offshore waters and deep sea waters. Reasonable exploration, development and utilization of my country's offshore oil and gas resources has gradually become an inevitable choice to alleviate China's energy problems. . [0003] As an economical and effective way of oil and gas transportation, submarine pipelines also face a variety of risks. They may be damaged by third parties such as ship ancho...
