Abstract

PURPOSE:To efficiently deal with the restriction of the volume of an engine room by arranging the main engine in a stern engine room in the direction of width of a hull. CONSTITUTION:A main engine 2 is arranged in the direction of width of a hull A, and the first propulsion shafts 4 and 4 projecting outward from a hull outer plate 1' through bearings 5 and 5' are connected to the output shafts 3 and 3 projecting from the both sides of the main engine 2. The second propulsion shafts 6 and 6 which cross at right angles to the propulsion shafts 4 and 4 and are installed in the stern direction are connected at the top edges of the first propulsion shafts 4 and 4, and propellers 7 and 7 are installed. Further, the korto rudders 8 and 8 surrounding the propellers 7 and 7 are installed through turning shafts 8' and 8' onto the second propulsion shafts 6 and 6, and said turning shafts 8' and 8' are turned by a driving means, and the direction of the Korto rudders 8 and 8 can be changed. Therefore, the direction of water stream on the propellers 7 and 7 can be changed, and direction change of the ship through the steering operation is permitted.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention efficiently copes with engine room capacity constraints even when adopting a stern shape with good propulsion efficiency in terms of hull propulsion and an enlarged cargo capacity. This relates to ships that can

[Prior art and its problems]

Conventionally, as shown in the schematic bottom view of the stern portion of a ship, the main engine 14 is disposed in the longitudinal direction of the hull A, the propulsion shaft 15 is extended in the stern direction, and the rear end of the main engine 14 is disposed in the longitudinal direction of the hull A. A propeller 16 is attached to the propeller 16, and a rudder 17 is provided behind the propeller 16.

However, in recent years, in order to increase the energy saving effect,
There are many requests to improve the shape of the stern to improve propulsion efficiency and to place the engine room as close to the stern as possible in order to secure cargo capacity. There was a problem that I couldn't solve.

[Purpose of the invention]

Therefore, an object of the present invention is to solve the above-mentioned problems, and even when a stern shape with good propulsion efficiency and an enlarged cargo capacity are adopted, it is possible to cope with the engine room capacity restriction. The objective is to provide a ship with an efficient engine room layout.

[Summary of the invention]

The ship of the present invention has a main engine disposed in the stern engine room in the width direction of the ship, an output shaft of the main engine protruding from both ends thereof,
Each of the output shafts has a first shaft that protrudes outward from the ship's side skin.
The propulsion shafts are connected to each other, and a second propulsion shaft having a propeller attached to the tip is connected to each end of the first propulsion shaft so as to be orthogonal to the first propulsion shaft and directed toward the stern. It is characterized by the fact that a Cort rudder is rotatably provided around the propeller with two propulsion shafts.

[Structure of the invention]

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a horizontal sectional view of a stern portion showing one embodiment of the present invention, and FIG. 2 is a longitudinal sectional view thereof.

In the drawings, reference numeral 1 indicates the ship's side outer plate, and 1' indicates the ship's side outer plate at the position where the propulsion shaft is attached. In this invention, the main engine 2 is arranged in the width direction of the hull A.

The main engine 2 has an output shaft 3゜3 protruding from both sides of the main engine 2, and each of the output shafts 3, 3 is provided with a shaft 3, which protrudes outward from the side shell plate 1' via bearings 5, 5. 1 propulsion shafts 4, 4 are connected.

Second propulsion shafts 6, 6, which are perpendicular to the propulsion shafts 4, 4 and face toward the stern, are connected to the tips of the first propulsion shafts 4, 4, for example, by gears. A propeller 7.7 is attached to each tip. Further, a propeller 7 is connected to the second propulsion shafts 6, 6 via rotation shafts S/, S/.
．． Kort rudders 8, 8 are provided surrounding the Kort rudders 8, 8, and by rotating the pivot shafts S/ and S/ by a drive means not shown, the propeller can be rotated by changing the direction of the Kort rudders 8.8. By changing the direction of the water flow at a angle of 7°7, the direction of the vessel can be changed by the action of the steering wheel. The Cort Lada 8, 8 can also improve the propulsion efficiency of ships.

In Fig. 1, 9 indicates auxiliary equipment such as generators, coolers, pumps, etc. In Fig. 2, 10 is the upper deck, 11 is the bottom shell, 12 is the double bottom, and 13 is the rose 3. = Stock tank or cargo hold.

〔Effect of the invention〕

Since the present invention is constructed as described above and the main engine 2 is disposed in the width direction of the hull A, the shape of the stern portion can be made as shown by the two-dot chain line in FIG. Therefore, since the engine room can be placed at the rear end of the ship, the cargo hold can be enlarged by that amount, and if there is no need to enlarge the cargo hold, the length of the hull can be shortened.

Furthermore, since the propellers 7.7 are placed on both sides, when the output from the main engine 2 is changed, the maneuverability of the ship can be improved compared to before, and the width of the stern can be made wider. Since it is possible to do so, sufficient space in the engine room can be secured, and the direction of the ship can be easily changed using the Col rudders 8, 8.

Moreover, many excellent effects are brought about, such as the propulsion shaft can be easily pulled out and the weight of the hull can be reduced.
