Device for propelling and turning hull

Abstract

The present invention relates to a device for propelling and turning a hull, wherein the resistance acting on the stem of the hull is converted and the hull can be moved not only in the forward and backward directions but also in the left and right directions so as to improve the mobility and evasion capacity of the hull. The device for propelling and turning a hull comprises: a manifold arranged in the lengthwise direction in the lower portion of the hull so as to discharge the water introduced at the stem side toward the stern side; a propelling means, the top of which is rotatably connected to the stern side end of the manifold, the propelling means being arranged so as to jet water in a lateral direction; and a steering means, which is rotatably coupled to the stern side end of the propelling means such that the steering means rotates the propelling means in a given direction by means of rotating force applied from an external source.

1 . A device for propelling and turning a warship or a ship, the device comprising:
 a manifold installed in a lengthwise direction in a lower portion of the warship ox the ship and that discharges water introduced into the stem side to the stern side;   a propulsion means having a lower end portion rotatably connected to an end portion of the stern side of the manifold and that ejects water in a side direction; and   a steering means rotatably coupled to an end portion of the stern side of the propulsion means and that rotates the propulsion means in a random direction through rotatory power applied from the outside.   
     
     
         2 . The device of  claim 1 , wherein the propulsion means comprises:
 a housing having an upper end portion inserted into the inside or the outside of one end of an end portion of the stern side of the manifold to be rotatably coupled;   an ejection pipe having one end connected to a side portion of the housing to eject introduced water through a water outlet extended relatively lower than the manifold; and   a rotation support plate having one end coupled and fixed to the stern so as to support the bottom in order to prevent the housing from moving to the lower side while rotating.   
     
     
         3 . The device of  claim 1 , wherein the steering means comprises:
 a steering shaft vertically disposed to the warship or the ship;   a steering gear installed in an end portion of the steering shaft to rotate in a predetermined direction; and   a propulsion gear installed at an external surface of the propulsion means to engage with the steering gear.   
     
     
         4 . The device of  claim 1 , wherein the manifold comprises:
 a main pipe that forms a water inlet with the opened stem side; and   a plurality of auxiliary pipes disposed in a lateral direction of the main pipe and in a width direction of the warship or the ship.   
     
     
         5 . The device of  claim 1 , wherein the manifold comprises:
 a main pipe in which a pair of branch pipe channels are formed at both sides in a lengthwise direction at the center of a lower portion of the warship or the ship; and   a plurality of auxiliary pipes each having one end connected to each branch pipe channel of the main pipe to be disposed in a width direction of the warship or the ship, wherein a valve v is mounted immediately before the auxiliary pipe.   
     
     
         6 . The device of  claim 1 , wherein the manifold comprises:
 a main pipe installed in a lengthwise direction at the center of a lower portion of the warship or the ship;   a supply pipe installed in a lower portion of the main pipe along the main pipe and having the opened front side and the closed rear side;   a plurality of auxiliary pipes disposed in a lateral direction of the supply pipe and in a width direction of the warship or the ship; and   a valve v mounted immediately before the auxiliary pipe.   
     
     
         7 . The device of  claim 1 , further comprising at least four direction adjusting means that move the warship or the ship to the right side or the left side by a small margin or that turn the warship or the ship. 
     
     
         8 . The device of  claim 7 , wherein the direction adjusting means comprises a plurality of adjusters having a screw propeller and a rotation shaft in a uniform gap at one side of a lower portion of the manifold or on the manifold and ejects seawater to the left side or the right side by driving each of the adjusters. 
     
     
         9 . The device of  claim 7 , wherein the direction adjusting means turns the warship or the ship clockwise or counterclockwise by rotating the seawater in a left direction or a right direction or by rotating the seawater in a right direction or a left direction using the adjuster and rotates the warship or the ship clockwise or counterclockwise by a rotation of the adjuster when the warship or the ship is in a stop state. 
     
     
         10 . A device for propelling and turning a warship or a ship, the device comprising:
 a manifold installed in a lengthwise direction in a lower portion of the warship or the ship and that discharges water introduced through a water inlet opened at the stern side to the stem side through an upper downward inclined surface, wherein the upper downward inclined surface is formed at a predetermined segment of an upper end portion of the stern side;   a propulsion means rotatably connected to an upper end portion of the stern side of the manifold and having a lower downward inclined surface formed to correspond to a shape of an upper end portion of the stern side of the downward inclined manifold and having a horizontal segment formed to eject water in a horizontal direction; and   a steering means fixed to a bottom surface of the propulsion means and that rotates the propulsion means in a random direction through rotatory power applied from the outside.   
     
     
         11 . The device of  claim 10 , wherein at the stem side of the manifold, a screw propeller that generates a propulsive force by receiving and rotating a driving force from the engine is installed. 
     
     
         12 . The device of  claim 10 , wherein an acceleration guide pipe is installed parallel to a lower end portion of the manifold, has at least four direction adjusting means installed in a predetermined gap therein, and has a valve v mounted immediately before the auxiliary pipe. 
     
     
         13 . The device of  claim 12 , wherein in an upper end portion at a random location of the acceleration guide pipe and in an upper end portion of the propulsion means, an injection device of a jet engine and a powerful air blower are installed, respectively. 
     
     
         14 . (canceled) 
     
     
         15 . The device of  claim 12 , wherein the respective direction adjusting means selectively execute operation of rotating the warship or the ship in a left direction or a right direction, pushing the warship or the ship to the front side or the rear side, or stopping the warship or the ship.
