Model test device and test method for measuring penetration attitude of torpedo anchor in seabed slope

Abstract

The invention provides a model test device and a test method for measuring the penetration attitude of a torpedo anchor in a seabed slope. The device comprises a torpedo anchor, a cylinder, a soil box, an anchor body, an anchor head, a tail wing, a positioner A, a positioner B, a pull rope, a slope, a bracket, a fixing ring, a flange plate, a bolt and a signal detector. The influence of the slope angle alpha and the penetration speed v on the penetration posture and the penetration depth is determined by simulating the penetration posture of the torpedo anchor after the torpedo anchor penetrates into the seabed slope, so that an analysis basis is provided for researching the penetration posture and the penetration depth of the mooring foundation of the ocean platform in a seabed slope area. The problem that the uplift bearing capacity of a mooring foundation cannot be effectively exerted due to the fact that the penetration posture of a torpedo anchor in a slope stratum is poor or the penetration depth is insufficient is solved.

Description

technical field [0001] The invention belongs to the technical field of mooring foundation devices, and particularly relates to a model test device and a test method for measuring the penetration attitude of a torpedo anchor in a submarine slope. Background technique [0002] At present, the exploitation of marine resources has entered the ultra-deep water field. Marine floating structures, such as offshore drilling platforms, floating production, storage and unloading devices, are essential facilities for marine resource exploitation. As an important part of the marine floating structure, the mooring system increases the construction cost and construction difficulty with the increase of the scale and water depth of the marine structure. The torpedo anchor is simple and quick to install and has low manufacturing cost, and is a promising deep-sea anchoring structure. The problem currently encountered is that the research on the penetration attitude of the torpedo anchor in t...

Problems solved by technology

[0006] The purpose of the present invention is to solve the deficiencies and defects that exist in the prior art, and provide a model test device and a test method for measuring the penetration attitude of the torpedo anchor in the seabed slope, by simulating the penetration attitude of the torpedo anchor after penetrating the seabed slope, determine The influence of the slope angle α and the penetration velocity v on the penetration attitude and penetration depth provides an analysis basis for the study of the penetration attitude and penetration depth of the mooring foundation of the offshore platform in the submarine slope area, and solves the problem of torpedo anchors on the slope. Poor penetration posture or insufficient penetration depth in the stratum lead to the problem that the uplift bearing capacity of the mooring foundation cannot be effectively exerted
