Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] like figure 1 As shown, the full-scale submarine pipeline falling objects impact simulation test system of the present invention specifically includes a movable impact test tower, a set of test pipeline support foundations, a set of falling objects and its lifting release mechanism.

[0037] The system consists of three parts: one part is a movable impact test tower 3, such as figure 1 As shown, it includes the upper steel tower structure and the lower four test tower tower wheels 2. The test tower tower wheel 2 bears the weight of the entire tower and straddles the two test tower guide rails 11, and can be moved along the guide rails under artificial promotion to change the position of the test tower 3 to different pipeline support sites. The tower wheel 2 of the test tower is made up of directional plates 21, spokes 22, steel rims 23 and wh...

Abstract

The invention relates to a simulation test system of a falling object impact on a submarine pipeline. The system is composed of a movable impact test tower, a test pipeline support foundation set, a falling object group and a lifting and releasing mechanism thereof. The movable impact test tower consists of a steel tower rack and four tower wheels supporting the tower rack; and the four tower wheels cross cover two test tower guide rails. The test pipeline support foundation set includes a rigid support foundation, a suspended spanning support foundation and a soil support foundation. The lifting and releasing mechanism includes a guiding mechanism, a suspension cable, a suspension cable releasing lock latch, two fixed pulleys and a lifting reel. The system has advantages of simple structure, simple processing, simple mounting and dismounting, low construction cost, good state control performance, high repeatability, and reduced testing difficulty and cost.

Description

Technical field [0001] The invention belongs to the technical field of development, operation and maintenance of offshore oil and gas projects, and relates to a simulation test system for the impact of falling objects on submarine pipelines. Background technique [0002] The 21st century is the century of the ocean, and it is an important proposition both for China and the world. The ocean is a new and important resource space on which human beings rely for development in the new century. Accelerating the development of the ocean has become the consensus of all marine countries. Traditional marine resources represented by oil and natural gas have been continuously improved and expanded in development technology, and new marine resources such as combustible ice and seabed mineral deposits have also attracted more and more attention from engineering developers. In marine resources development technology, submarine pipelines play an irreplaceable role, providing basic conditio...
