Experiment device and experiment method for deep sea mining conveying hose spatial structure

Abstract

The invention discloses an experiment device and an experiment method for a deep sea mining conveying hose spatial structure. The experiment device comprises a pool, a pipe morphology acquisition device, a bottom displacement simulation device, a conveying hose simulation device and a camera, wherein the bottom displacement simulation device is fixed on the bottom surface of the pool; the pipe morphology acquisition device is fixed at the upper end of the pool; the pipe morphology acquisition device comprises a hose position detector and a hose position detector displacement device; the conveying hose simulation device is connected between the bottom displacement simulation device and the pipe morphology acquisition device. Transverse and longitudinal positions of the lower end of the conveying hose simulation device can be changed by the bottom displacement simulation device, the camera is fixed on a side wall of the pool to capture the spatial form of a pipe under water, the spatialform of the pipe under water is embodied by changing the positions of the hose position detector and acquiring spatial coordinates of different positions of the pipe, meanwhile, the spatial coordinates of the pipe in the positions are recorded, and thus the actual spatial form of the pipe under water can be acquired.

Description

technical field [0001] The invention belongs to the mining field of deep-sea solid mineral resources such as deep-sea manganese nodules, deep-sea polymetallic sulfides, and cobalt-rich crusts, and specifically relates to an experimental device and an experimental method for the spatial configuration of deep-sea mining transportation hoses. Background technique [0002] Among the continuous production systems of deep-sea solid mineral resources that have been developed, the pipeline lifting mining system has the most development and application prospects. The conveying hose is the key part connecting the ore lifting subsystem and the ore collecting subsystem in the pipeline lifting mining system. A key content in the design of the hose conveying system for deep sea mining is the estimation of the restraint reaction force at the mining vehicle end of the hose and the design of the space configuration of the hose. The deep-sea mining hose conveying system contains many parts a...

AI Technical Summary

Problems solved by technology

The deep-sea mining hose conveying system contains many parts and the boundary conditions are relatively complex. The theoretical analysis method can only use a simplified analysis model, which is difficult to accurately reflect the real shape of the conveying hose during operation.
