BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vane wheel for a ship for propelling a ship and a ship including the same.

As vessels become larger and faster, most ships now have propulsion by installing large propellers. These large propellers can change the flow of the fluid by rotation and change the fluid velocity accordingly. The change in the fluid velocity causes cavitation (Cavitation) in which the fluid in the liquid state changes to the gaseous state as the ambient pressure drops below the vapor pressure of the fluid. Cavitation is a phenomenon in which a cross section of flowing water changes suddenly or a direction of a flow changes, causing cavities in the vicinity of the flowing water, causing swirling. Such cavitation causes noise and vibration in the partial load (partial load), and causes corrosion in the back surface of the wing car in the heavy load.

FIG.

2 to 6, the vane wheel 1 according to the present invention is rotated together with the propeller 6 by the driving force of the engine 300 to generate propulsion force, thereby propelling the hull 500 . The propeller 6 is rotated by a driving force of the engine 300 provided through the rotary shaft 200 to push fluid out of the hull 500 and generate thrust to propel the hull 500. The engine 300 may include a gasoline engine, a diesel engine, a turbine engine, or the like, which provides a driving force for rotating the propeller 6 through the rotary shaft 200.

To this end, the marine vane wheel 1 according to the present invention includes a main body 2 coupled to a ship, and a plurality of wing portions 3 rotated together as the propeller 6 for propelling the marine vessel rotates do. The wing portions 3 are respectively connected to the main body 2 to rotate together with the propeller 6 to generate a rotational force, and the first wing portions 3 are formed of a composite material, And a second rotation part 32 coupled to the first rotation part 31 and made of a metal material so as to rotate together to generate a driving force as the rotation part 31 rotates. The second rotation part 32 includes an insertion groove 321 into which the first rotation part 31 is inserted and is coupled to the first rotation part 31 so as to protrude to the outside of the propeller 6.

The wings 3 are coupled to the main body 2 and the main body 2 is coupled to the rotation shaft 200. The wing portions 3 can be freely rotated irrespective of the driving force provided by the engine 300. [ The wings (3) are formed longer than the wings of the propeller (6). The wing portion 3 may be formed by coupling the first rotating portion 31, which is a composite material, and the second rotating portion 32, which is a metal material.

Therefore, the marine vane wheel 1 according to the present invention can achieve the following operational effects.

First, the vane wheel (1) according to the present invention is designed to prevent erosion and delamination by cavitation caused by rotation of the propeller (6), thereby prolonging the service life and reducing maintenance cost can do.

Second, the marine vane wheel 1 according to the present invention is formed longer than the wing portion of the propeller 6, and is rotated together with the thrust of the fluid generated as the propeller 6 rotates, But can reduce the energy supplied to propel the ship.

Hereinafter, the main body 2 and the wing 3 will be described in detail with reference to the accompanying drawings.

2 to 5, the main body 2 is coupled to the ship. The main body 2 is rotatably coupled to the rotation shaft 200 and the rotation shaft 200 is coupled to the engine 300 so that the main body 2 can be coupled to the ship. The body (2) is rotated as the wing (3) is rotated. The wing 3 can be rotated by the thrust of the fluid generated by the rotation of the propeller 6 provided with the driving force of the engine 300. The main body 2 is formed in a cylindrical shape so that friction with the fluid generated by the rotation of the main body 2 can be minimized.

2 to 6, the wing 3 is coupled to the main body 2. The wing 3 rotates together with the propeller 6 to generate a rotational force. The wing portion 3 may be formed in a spiral shape to generate a thrust force.

For example, when the wing portion 3 rotates in one direction, a contact portion that is located in the rotational direction of the wing portion 3 and pushes the fluid at an initial stage is referred to as a suction surface, The wing portion 3 is formed in a spiral shape so that the pressure of the suction surface is lowered as the wing portion 3 is rotated and the pressure of the pressure surface is lowered as the pressure portion is brought into contact with the remainder of the wing portion 3, . The wing portion (3) pushes the fluid by using a pressure difference between the suction surface and the pressure surface, thereby generating thrust to propel the ship.

The wings 3 may be coupled to the main body 2 in a plurality of ways. The plurality of vanes 3 may be spaced apart from each other in the main body 2. The thrust generated by the plurality of vanes 3 may be greater than the thrust generated by the vanes 3 of less than a plurality. For example, the thrust generated by the six wing portions 3 may be larger than the thrust generated by the two wing portions 3.

The wing portion 3 may be a fixed pitch propeller fixedly coupled to the main body 2. The wing 3 may be a variable pitch propeller rotatably coupled to the main body 2. The variable pitch propeller may change the direction of the thrust by adjusting the angle of engagement of the wing 3 coupled to the main body 2 to reverse the ship. The variable pitch propeller may be installed on a ship such as a tugboat or a trawl ship which has a large propeller load change or a ship which can not be reversed, such as a gas turbine.

The speed of the ship can be changed by adjusting the rotational speed of the wing 3 according to the magnitude of the driving force provided by the engine 300. For example, when the size of the driving force provided by the engine 300 is small, the speed of the ship can be reduced by decreasing the number of revolutions. For example, when the magnitude of the driving force provided by the engine 300 is large, the wing portion 3 can increase the speed of the ship by increasing the number of revolutions.

The wing (3) can change the direction in which the ship moves. For example, the wing 3 can advance the ship by rotating together as the propeller 6 rotates in a first direction (R1, shown in FIG. 6). For example, the wing 3 may rotate together with the wing 3 as the propeller 6 rotates in a second direction R2 (shown in FIG. 6) opposite to the first direction.

Referring to FIGS. 3 to 6, the wings 3 may include a first rotation part 31, respectively.

The first rotation part (31) is coupled to the main body (2). The first rotary part 31 may be rotated together with the thrust of the fluid generated as the propeller 6 rotates. Accordingly, the first rotation part 31 can generate a rotational force.

The first rotation part 31 may be formed of a composite material. The first rotation unit 31 may include at least one of carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP). The first rotation part 31 can be formed by combining and laminating the above-mentioned materials.

Accordingly, in the marine vane wheel 1 according to the present invention, the first rotating portion 31 can achieve the following operational effects.

First, in the marine vane wheel 1 according to the present invention, the first rotation part 31 is formed of a composite material, thereby simplifying the shafting and stern side structures according to the light weight, thereby reducing manufacturing costs.

Second, in the marine vane wheel 1 according to the present invention, the first rotary part 31 reduces the friction with the hull 500, which is generated as the rotary shaft 200 rotates as the weight is light, The maintenance cost can be reduced by extending the service life.

Third, in the marine vane wheel 1 according to the present invention, since the first rotating part 31 is less in noise and vibration than when it is formed of a metal material, it can be used as a propulsion device for a special purpose such as a warship or a submarine have.

However, in the marine vane wheel 1 according to the present invention, if the entire wing portion 3 is formed of a composite material, it is difficult to process and increase manufacturing costs, and resistance to erosion caused by cavitation This weakness may cause delamination. Accordingly, the marine vane wheel 1 according to the present invention can improve the disadvantages of the composite material and maintain the advantages of the composite material by forming the wing portion 3 from a composite material and a metal material.

Referring to FIGS. 3 and 6, the wing 3 may include a second rotation part 32.

The second rotation part 32 is coupled to the first rotation part 31. Accordingly, the second rotation part 32 can be coupled to the main body 2. The second rotation part 32 may be rotated together with the first rotation part 31 as it rotates. As the second rotation part 32 rotates, propulsion force is generated to propel the ship.

The second rotation part 32 may be formed of a metal material. The second rotation part 32 may be formed of a nickel-aluminum (NiAl) bronze alloy.

Accordingly, in the marine vane wheel 1 according to the present invention, the second rotating portion 32 can achieve the following operational effects.

First, in the marine vane wheel 1 according to the present invention, since the second rotating part 32 is formed of a metal material, it is easier to process than a composite material, and the material cost can be reduced.

Second, in the marine vane wheel (1) according to the present invention, the second rotating part (32) can increase the mechanical property, which is a property corresponding to various loads, as compared with the composite material.

Third, in the marine vane wheel 1 according to the present invention, the second rotating part 32 is made of a metal material and is resistant to erosion caused by cavitation by being coupled to the first rotating part 31, .

However, in the vane wheel 1 according to the present invention, if the entire wing portion 3 is formed of a metal material, a load is increased due to a considerable load on the shaft system, so that heat can be generated, It may not be suitable for special purpose propulsion devices such as warships and submarines. Therefore, the marine vane wheel 1 according to the present invention can improve the disadvantages of the metal material and maintain the advantages of the metal material by forming the wing portion 3 from a composite material and a metal material.

3 to 5, the second rotation part 32 may include an insertion groove 321. [ The insertion groove 321 is a space formed inside the second rotation part 32. The first rotation part 31 may be inserted into the insertion groove 321. The size of the insertion groove 321 may be changed according to the size of the first rotation part 31 inserted. Therefore, the insertion groove 321 may be formed to have a size such that the entire first rotation part 31 is inserted.

3 and 4, the insertion groove 321 is formed to have a size to which a part of the first rotation part 31 can be inserted, so that a part of the first rotation part 31 is inserted into the insertion groove 321 321, the second rotation part 32 can protect a part of the first rotation part 31 from erosion.

5, the insertion groove 321 is formed to have a size such that the entirety of the first rotation part 31 can be inserted, so that the entire first rotation part 31 is inserted into the insertion groove 321 The second rotation part 32 can protect the entire first rotation part 31 from erosion.

Therefore, in the marine vane wheel 1 according to the present invention, the first rotating portion 31 can be protected from erosion by the second rotating portion 32 according to the size of the first rotating portion 31 inserted into the insertion groove 321 , The first rotating portion 31 can increase the resistance to erosion by inserting a portion where erosion is frequently generated into the insertion groove 321, thereby extending the service life.

2 to 6, the second rotation part 32 is coupled to the first rotation part 31 so as to protrude to the outside of the propeller 6. The length L of the wing 3 (shown in FIG. 3) is longer than the wing length of the propeller 6. L is a real number greater than zero. The second rotation part 32 may have a length of 0.02 L or more and 0.5 L or less. The second rotation part 32 may be partially or wholly connected to the first rotation part 31. [

Hereinafter, the second rotation part 32 is partially or completely coupled to the first rotation part 31 will be described in detail with reference to the accompanying drawings.

Referring to FIG. 3, the second rotation part 32 may be partially coupled to the first rotation part 31. In this case, the minimum length of the second rotation part 32 is 0.02L. Assuming that the portion of the first rotating portion 31 coupled to the main body 2 is 0, the starting point of the second rotating portion 32 is 0.98L, and the end point is L.

Therefore, the vane wheel 1 according to the present invention is constructed such that the outer side of the wing portion 3, which is most vulnerable to cavitation generated by the rotation of the wing portion 3, is protected by the second rotation portion 32, Thereby increasing the resistance to erosion. The second rotation part 32 may be coupled to the first rotation part 31 by coating.

Referring to FIG. 4, the length of the second rotation part 32 is 0.5L. In this case, assuming that the portion of the first rotating portion 31 coupled to the main body 2 is 0, the starting point of the second rotating portion 32 is 0.5L, and the end point is L.

Accordingly, the vane wheel 1 according to the present invention is not only capable of increasing the resistance to erosion caused by cavitation generated in the region from 0.5 L to L by forming the second rotating portion 32 of metal material It is possible to prevent the wing portion 3 from being damaged or damaged by increasing the strength more than when the second rotating portion 32 is formed of a composite material. The second rotation part 32 may be coupled to the first rotation part 31 by coating.

Referring to FIG. 5, the second rotation part 32 may be fully coupled to the first rotation part 31. FIG. In this case, the maximum length of the second rotation part 32 is L. Assuming that the portion of the first rotating portion 31 coupled to the main body 2 is zero, the starting point of the second rotating portion 32 is zero, and the end point is L.

Therefore, in the marine vane wheel 1 according to the present invention, the second rotating part 32 is formed of a metal material and protects the first rotating part 31 in the area from 0 to L, thereby preventing erosion caused by cavitation It is possible to prevent the wing portion 3 from being damaged or damaged by increasing the strength more than when the second rotating portion 32 is formed of a composite material. The second rotation part 32 may be coupled to the first rotation part 31 by coating.

The marine vane wheel 1 according to the present invention can improve the resistance to erosion by combining the first rotating portion 31 formed of a composite material and the second rotating portion 32 formed of a metal material, And metal material. Therefore, it is possible to reduce the maintenance cost by extending the service life.

Referring to FIG. 6, the second rotating part 32 may be coupled to the first rotating part 31 so as to be positioned outside the slip stream 400 generated when the propeller 6 rotates. The slip stream 400 is relatively low in pressure relative to other places where the propeller 6 is rotated to generate propulsive force. The first rotary part 31 can be easily rotated by the thrust of the fluid generated by the rotation of the propeller 6 by being located in the slipstream 400. The second rotation part 32 may rotate together with the first rotation part 31 as it rotates.

Therefore, the vane wheel 1 for a ship according to the present invention is rotated by the thrust of the fluid generated as the propeller 6 rotates and is formed longer than the wing portion of the propeller 6, The thrust generated by the portion A (shown in Fig. 6) with respect to the ship can be further improved. The portion A is a thrust of fluid generated as the first rotating portion 31 and the second rotating portion 32, which are rotated outside the slipstream 400, are rotated.

The propeller 6 propels the hull 500. The propeller 6 is coupled to a rotary shaft outside the hull 500, and the rotary shaft is coupled to the engine. The propeller 6 may be rotated together by rotating the rotary shaft provided with the driving force by the engine. The propeller 6, which is rotated, can generate thrust by pushing the fluid by the rotational force. Accordingly, the hull 500 can be propelled.

In an embodiment of the vessel 7 according to the present invention, the vane wheel is rotatably coupled to the propeller 6, and the thrust of the fluid generated as the propeller 6 is rotated causes the vane wheel to rotate So that the ship can be propelled with a greater thrust than when the propeller 6 is rotated to propel the ship.

The rudder (4) receives fluid pushed as the propeller (6) and the vane wheel rotate. The rudder 4 can change the direction of propulsion of the hull 500 by changing the direction of the fluid being pushed.

For example, when the rudder 4 rotates to the right, the fluid generates thrust in the right direction along the direction of the rudder 4. As the stern of the hull 500 is propelled in the left direction opposite to the thrust direction of the fluid, the head of the hull 500 is directed to the right. As a result, the vessel 7 according to the present invention can be propelled to the right.
