Background technique

The underwater transportation system is a very important part of the deep-sea mining system, which transports the minerals collected by the mining vehicle to the surface carrier. At present, the commonly used underwater transportation systems include two types of continuous transportation and discontinuous transportation. Continuous transportation mainly refers to the direct transportation of minerals from the mining truck to the surface carrier through the pipeline. Generally, there are methods such as hydraulic lifting and pneumatic lifting; discontinuous The transportation is by placing the minerals in the storage bins and transporting them to the surface of the water through the hoisting cabins with or without cables. The continuous conveying system has high conveying efficiency, but the deployment and recovery are complicated, and it is greatly affected by sea conditions. Moreover, the pipeline of several kilometers long puts high requirements on the surface carrier. The discontinuous conveying system does not require slender conveying. The pipeline has high adaptability to sea conditions, simple deployment and recovery operations, and can improve transportation efficiency by adding multiple lifting cabins.

When the existing discontinuous conveying system is working, the lifting cabin is deployed, recycled, and unloaded manually, which has problems such as high labor intensity, high labor cost, low efficiency, and low safety.
