Large-tonnage Hai-river direct service ship

Abstract

The invention discloses a direct conveying ship of big-tonnage river, which comprises the following parts: bulk, tail, driving chamber, each operating part, lifting head, stable fin, wherein the driving chamber is set on the deck, which is lifted with head; the head pusher is set on the lower part of head column; the ship keeps stable running, which saves cost.

Description

technical field [0001] The invention relates to a ship, especially a large-tonnage sea-river direct transport ship that can directly reach the waters of coastal and inland river tributaries, compared with inland river tributaries (such as canal fourth-grade waterways). The ship is suitable for water transportation between Yangshan Port in Shanghai and Suxichang, a tributary of the Yangtze River, and small ports in the hinterland of Hangjiahu. Background technique [0002] Due to the different water environment between the sea and the tributaries of inland rivers, such as the wide (deep) sea area and strong wind and waves, the narrow and shallow (curved) restrictions and small wind and waves of the tributaries of inland rivers, two types of completely different ship types and types have been formed in history. The main dimensions, in addition to their great differences in scale, under the same loading conditions, or under the same main dimensions, the characteristics of sea-g...

Problems solved by technology

2. The draft is relatively deep, which does not match the water depth conditions of the inland waterway and cannot enter the problem (for example, a thousand-ton sea-going ship has a draft of more than 4 meters, while the water depth of the inland river is often about 2 meters), so objectively, the sea and the river cannot be entered. Direct access, the contradiction that transportation must be transferred to the port or barge, greatly increases the transportation cost and turnaround time, and increases the chance of cargo damage and poor cargo, which is very unfavorable to the development of water transportation.

Although this kind of ship solves the problem of river-sea combined transport, it also has problems such as high technical requirements when replacing the push wheels, troublesome replacement process, and high cost of the entire ship.
