Description

Inland river small ship body arrangement structure

Technical Field

The utility model belongs to the technical field of shipbuilding, in particular to small-size hull arrangement structure in inland river.

Background

The existing river and large ship are equipped with working ship, which is used for transportation and small cargo transfer when the ship is not on the bank wall dock and the wharf dock is berthed, or the ship and ship, ship and bank need to come and go, or the small lot of goods and materials need to be turned over. However, in the actual situation, the design and construction randomness of the ship is large, the stability, the operation, the performance, the arrangement and the like are different, the number of small passenger (cargo) carrying ships without stable balance is large, and the serious property and the loss of lives and properties of people are caused by frequent small ship overturning accidents. The existing ship is generally small in depth, but the required navigational speed is high, the power matching of a main engine is high, the diameter of a propeller is required to be large, the propeller shaft system is inclined, and the gear box and the main engine are installed at an inclined angle, so that the stability of the operation of the gear box and the main engine is not favorable, the vibration and the noise are increased, and the problem that the small ship is difficult to solve is solved. In the existing small ships, due to the fact that the size is small, a propeller hanging machine is mostly adopted for a propulsion main machine, and due to the fact that the propeller hanging machine is installed at the stern, a driver needs to stand at the stern to operate, the center of gravity of the driver is high when the driver operates and stands, safety and reliability are poor, and the ship is generally only suitable for small power.

Therefore, the gear box and the main engine are arranged in the cabin of the small passenger (cargo) carrying ship as a better choice, compared with the small ship which adopts a large-power propulsion main engine, the arrangement of the paddle hanging machine is impossible because the weight is larger than that of the paddle hanging machine, and the area for installing the gear box and the propulsion main engine can only be arranged on the main hull of the small ship, so that the area of the gear box and the main engine occupies the limited passenger (cargo) carrying area of the small ship, and in addition, the head and tail deck area for people to get on and off the ship needs to be arranged at the head and the tail of the small ship, the main scale of the small ship is limited, but a propeller with a larger diameter is needed, the principle that the propulsion efficiency is higher when the diameter of the propeller is larger, the propulsion efficiency is higher is generally accepted in the industry, the principle that the axis of the propeller is obliquely arranged, and the gear box and the main engine are also obliquely arranged, the arrangement is unfavorable for the safe operation of the propulsion main engine, and the propulsion efficiency of the propeller is also reduced. In addition, the steering device is required to be arranged for steering, the gear box is in reversing clutch, and the main engine is required to be accelerated and decelerated to occupy a part of space, so that the small limited space is remained, and the difficulty in arrangement is a big problem of the small-sized ship.

Therefore, the utility model discloses the main problem that solves does: a more reasonable optimization combination is found, so that the tail shaft tail pipe assembly, the driving device, the gear box and the main engine do not occupy too much space of a passenger cabin or a cargo hold, a passenger (cargo) carrying area has a large area, and the motion stability of a ship body is ensured.

In addition, the utility model discloses the secondary problem that solves does: small passenger (cargo) ships, which need to be equipped with signalling devices and 2 search lights, should not have superstructures or deckhouses with large wind areas and ensure stability margins in order to reduce the height of the centre of gravity of the ship, due to stability requirements. Generally, roofs and deck rooms are not designed, and then, searchlights and signal lamps need to be arranged by special design, which also needs to be designed in a searchlight manner.

A further secondary problem is: small-size boats and ships should have the buoyancy body, when this boat breaks down and takes place to heel, still can be a buoyancy body that possesses buoyancy, all dresses the life vest in addition personnel when taking this kind of boat, can ensure to run into when heeling, depends on the buoyancy body personnel and can be safe. At the same time, the boat has buoyancy to ensure that property damage is minimized. The buoyancy body is permanently arranged, and the buoyancy provided by the buoyancy body is required to be more than or equal to 110% of the weight of the empty ship; while solving all the technical problems, the optimal arrangement of the buoyancy body must be considered, and the overall arrangement of the whole ship is also important. In addition, the main dimensions of a small ship are small, and how to skillfully arrange rudder equipment as best as possible to maximize the area of a passenger cabin (cargo compartment) is also one of factors to be considered.
