Background
The deep sea contains rich and high-grade mineral resources. However, deep-sea mineral deposits are generally distributed in sea areas with extremely deep water depths, and a lifting system is an important subsystem in a deep-sea mining system. The ore lifting system consists of a lifting pump and a transport vertical pipe, wherein the transport vertical pipe can adopt a flexible hose. Due to the low dead weight of the flexible hose and the low requirements for vessel motion, the flexible hose can accommodate locally greater water depths in mine areas and reduce equipment requirements for mining vessels.
However, the bending rigidity of the flexible hose is relatively low, so that the flexible riser can generate large deformation and dynamic response under the excitation of dynamic load of marine environment, the flowing of ore pulp in the hose is damaged, and the service life of the hose is obviously shortened.
Therefore, the ore mixing transportation hose with the auxiliary cable positioning function is needed to be invented, the deformation and the dynamic response of the hose are restrained, and the transportation applicability is improved.
