Self-propelled trailing suction offshore ore mining ship

Abstract

The invention relates to a self-propelled trailing suction offshore ore mining ship. The ship is provided with an offshore ore mining operation system. The self-propelled trailing suction offshore ore mining ship comprises a single suction pipe, an underwater ore suction pump, an ore screening box, a loading device, an ore hold, a dehydration system and a dry unloading system; and ore is mined through the single suction pipe, sucked in by the underwater ore suction pump, roughed by the ore screening box and then loaded into the ore hold through the loading device, the ore is washed with washing fresh water after being precipitated, then dehydrated through the dehydration system at the bottom of the ore hold, and after the ship runs to a designated ore unloading place, the ore is conveyed to an ore field through the dry unloading system consisting of a grab machine and a belt conveyor. A full-electric driving system is adopted, power distribution of a power device can be flexibly carried out in different environment conditions and different operation working condition ranges, a generator set can reach a proper power load state, proper power storage is achieved, fuel consumption is low, and environmental protection and energy saving are achieved.

Description

technical field [0001] The invention belongs to the technical field of ore mining engineering ship equipment, and in particular relates to a self-propelled drag suction offshore ore mining ship. Background technique [0002] With the rapid development of my country's national economy, the demand for mineral resources has increased sharply, and coastal placer has become an important type of mineral resource and has been developed and utilized; there are many types of coastal placer in my country, rich placer resources, and great potential for development and utilization . The mining of placer deposits below the water surface is currently mainly based on the mining of seabed surface sedimentary minerals. The current status of domestic ore mining ships is as follows: [0003] (1) The mining of seabed surface ore has not yet formed a large scale, and the mining water depth is relatively shallow. There is no suitable mining engineering ship for the mining of deep offshore metal p...

AI Technical Summary

Problems solved by technology

[0003] (1) The mining of seabed surface ore has not yet formed a large scale, and the mining water depth is relatively shallow. There is no suitable mining engineering ship for the mining of deep offshore metal placer.

[0004] (2) At present, my country's ore mining methods are relatively extensive. The sand mining ships used are only equipped with simple diesel-driven excavators on board, and most of them are non-self-propelled ships. The mechanization and automation of seabed ore mining equipment are low. Mining inefficiency
