Description

Self-discharging bulk cargo ship

Technical Field

The invention relates to the technical field of large cargo ship unloading, in particular to a bulk cargo ship capable of unloading materials automatically.

Background

At present, bulk ships are unloaded by a wharf ship unloader. The loading of bulk freighters requires a loading machine to carry out the loading operation on the wharf. Therefore, a wharf must be built for loading and unloading, which is a very capital and resource consuming project, especially for a large wharf for a large ship berthing, and in order to ensure the depth of water at the front of the wharf, the wharf is very difficult to construct and very high in capital consumption.

With the continuous development of globalization, a large amount of resources can be configured in the world, the intercontinental ultra-long distance transportation of the large amount of resources becomes a normal state, and due to the ultra-long distance, the ocean bulk cargo ship has an increasingly strong trend of large-scale production and an increasingly large ship type for reducing the transportation cost. For the source end of receiving large amount of resources, as the area using goods does not necessarily have deep water shoreline conditions, for example, when the factory is not on the coast and only river water channels can be used, multi-stage ship-unloading operation is adopted in the industry, and unloading operation of the factory beside the river water channels is realized. Particularly, a large-scale deepwater wharf is built on the coastal region, ocean vessel cargos are unloaded and loaded into a two-range ship by a deepwater wharf ship loader. The second ship transports the goods to the sub-deep water wharf near the river entrance, unloads the goods by the ship unloader of the sub-deep water wharf, loads the goods onto the river ship by the ship loader of the sub-deep water wharf, and transports the goods to the river wharf at the factory to complete the ship unloading operation. In order to reduce the dependence on deep water wharf resources and reduce the cost, a special ship with a ship unloader is also adopted in the industry for ship-passing operation, but due to the problems of low ship-discharging efficiency and safety and the problem of connection of a large ship to a small ship, the proportion of the mode is small, and the mode cannot become mainstream.

For the source end for sending out large amount of resources, a large wharf is built at a place with a proper deep water condition on the coastal to dock a large ship, and the deep water condition on the coastal determines the berthing of the large wharf, the size of the ship and the transportation cost of the raw materials sent out in the area. The problem of insufficient construction capital for constructing large wharfs in economic future areas such as developing countries is a factor that limits the size of ships.

Therefore, how to unload ships without depending on ports is a technical problem that needs to be solved urgently by technical personnel in the industry.
