[0001] SHIP PROPULSION DEVICE [0002]

[0001] The present invention relates to a ship propulsion device, and more particularly, to a propulsion device for propelling a ship by moving propulsion force by a pressure of water supplied to a water supply pipe of a plurality of propulsion bodies coupled to both sides of a rear side of a ship, The propulsion bodies can be rotated in the left and right directions by angular rotation so as to be able to steer the direction of travel of the hull so that the propulsion directions of the plurality of propulsion bodies can be positioned in the reverse direction by the backing means, Propulsion bodies can be raised to the water surface for maintenance or replacement in case of failure of propulsion bodies, or can be lowered into water after completion of maintenance or replacement. Since the propulsion force of the ship can be obtained by using the pressure of water, You can get a powerful propulsion system and an economical propulsion system without By adding several propulsion bodies to the ship's capacity without additional engine, it is possible to provide sufficient propulsion power from small vessel to large vessel, so it is possible to navigate smoothly by customized design according to vessel capacity It is possible to save the resources because the ship can be moved with relatively less power than using the huge engine to obtain the propulsion force. At the same time, it can reduce the size of the ship engine room drastically because it occupies a small volume, The engine room of the engine can be used for other purposes, and when a conventional propeller is operated, cavitation occurs between the tail of the ship and the propeller, so that propulsion is weakened and the speed of the sailing is not reduced. You can use a key like this to steer the hull Tagawa because the required two days set net or several floaters floating in the sea they will not take on the propulsion system of the vessel to a stable sailing.

Conventionally, the propulsion device of a ship is disclosed in "Laid-open No. 10-2011-0092668" Ship propulsion device ".

The conventional technique includes a hull fixing arm having a power line feeder for feeding a power line to the inside of the ship fixed to the hull of the ship;

A fixing shaft fixed to a lower side of the hull fixing arm and provided with a power line connecting port connected to the power line feeder;

And a propeller installed to rotate about the fixed shaft, wherein a stator, to which power is supplied via a power line, is attached to the fixed shaft,

A permanent magnet is provided on the inner circumferential surface of the propeller 30 so as to correspond to the stator so that the propeller is rotated about the stationary shaft by a normal interaction between the stator and the permanent magnet.

In the above conventional art, a motor unit composed of a stator and a permanent magnet is built on a central axis of a propeller, so that the propeller can be rotated about a fixed shaft, thereby greatly simplifying the structure of the entire propulsion device The present invention was conceived to provide a ship propulsion device that maximizes rotation efficiency and waterproof efficiency.

The conventional technique described above has a problem in that it is difficult to manufacture a propeller mounted and used to obtain a propulsion force of a ship because it is very precise and difficult to manufacture, and at the same time, a lot of cost is put into making a propeller.

In addition, in the above-mentioned conventional art, when the propeller is operated, cavitation occurs between the rear end of the ship and the propeller, and propulsion is weakened, so that the navigation speed is often reduced.

In addition, in the above-described prior art, since the rudder of the kyira was essential for steering the hull, it posed a problem that the fixed net and the various floats were caught in the key, and thus the navigation was obstructed.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems,

Since the propulsion force of the ship can be obtained by using the pressure of water, it is possible to obtain a strong propulsion device and an economical propulsion device without making a complicated propeller. If the propulsion bodies are additionally combined with the capacity of the ship without needing a huge engine, It is possible to provide a sufficient propulsion power from the ship to the large ship, so that it is possible to navigate smoothly by customized design according to the capacity of the ship. It is possible to use a relatively small power to drive the ship The size of the engine room can be greatly reduced due to the fact that it can save resources and occupy a small volume. Therefore, it is possible to use the existing engine room for other purposes, and at the time of operation of the conventional propeller, And the propeller It is possible to navigate in a safe condition because there is not a phenomenon that the propulsion force is weakened and the speed of the navigation is reduced. Therefore, since the rudder like the key is not needed for steering the hull, It provides the purpose of making stable voyage because there is no work.

According to an aspect of the present invention,

The hull can be moved by the pressure of water supplied to the water supply pipes of the plurality of propelling bodies coupled to both sides of the rear side of the hull, and the plurality of propelling bodies can be rotated So that the propulsion direction of the plurality of propulsion bodies can be positioned in the reverse direction by the backward means so that the hull can be moved backward. Then, when a plurality of propulsion bodies fail, The objects of the present invention can be accomplished by raising the propulsion bodies to the water surface or lowering them to the water after completion of maintenance and replacement.

According to the present invention as described above, since the propulsion force of the ship can be obtained by using the pressure of water, it is possible to obtain a powerful propulsion device and an economical propulsion device without producing a complicated propeller.

The present invention as described above can provide a sufficient propulsion force from a small ship to a large ship by combining several propulsion bodies in accordance with the capacity of the ship without requiring a huge engine, It has the effect of allowing smooth navigation.

The present invention as described above can save the resources because the ship can be moved using relatively less power than the propulsion using a huge engine, and at the same time, the size of the ship engine room It is possible to use the existing engine room for other purposes.

In the present invention as described above, cavitation phenomenon occurs between the rear end of the ship and the propeller when the propeller is operated, so that the propulsion force is weakened and the sailing speed is not reduced, .

The present invention as described above has a beneficial effect that a stable navigation can be performed because a rudder like a key is not required for steering the hull, so that a fixed net floating on the sea and various floats are not caught.
