Particularly, in the case of a propeller of a ship, a cavitation phenomenon occurs in which cavitation occurs when traveling at a high speed, resulting in a limitation in speed, and a problem such that a net or a rope is wound while the vehicle is running may cause a suspension or an accident.

In addition, since the direction of the axis is the direction of the axis, it is impossible to rotate the axis itself like a fan in a ship or an airplane.

The propeller used in such a wide range of fields is not efficient but has many disadvantages, so it can be operated by a rotating shaft, but the propulsion direction of the propeller can be overcome. The development of the thrust generating device is worth having.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram according to an embodiment of the present invention, FIG. 2 is a side view according to an embodiment of the present invention,

A main body 11 formed of a circular disk or a plurality of radial arms and rotated by power means; A supporting body 15 for supporting the main body 11 and incorporating power means for rotating the main body 11 and a central shaft 11 for vertically passing through the center of the main body 11 and the supporting body 15, And two or more vanes 112 vertically installed on the main body 11 are coupled to the respective mounting shafts 111 to be mounted at predetermined intervals in a radial manner, When the main body 11 rotates by 360 °, the wing 112 is rotated 180 ° in the opposite direction by connecting the fixed shaft 11 and the mounting shaft 111 to which the wing 112 is coupled when the main body 11 rotates. And each of the blades 112 is configured to rotate independently while rotating together with the main body 11 so as to form the same angle when they reach the same position, ) Is concentrated in a certain direction And the driving force generation device capable of adjusting the driving direction.

In general, when the structure like the wing 112 of the present application is rotated, the wind or fluid does not have directionality but acts as a square. However, when the wing 112 of the present invention cooperates with the rotational movement of the main body 11, When the wing 112 rotates 180 ° in the opposite direction when the body 11 rotates by 360 °, the wing 112 has a constant direction by the vector sum of the angles of the wings 112.

Herein, the main body 11 may be formed in the form of a circular disk as shown or may have a shape in the form of a plurality of radial arms extending in the direction of each wing 112.

The interlocking means 13 includes a first belt pulley 132 mounted on the central shaft 12 for mounting the belt 131 up and down by the number of the wings 112, And a second belt pulley 133 mounted on the mounting shaft 111. The timing belt is preferably mounted on the belt 131 to transmit the rotational speed of the first belt pulley 132, The outer diameter of the second belt pulley 133 is set to be half of the outer diameter.

In addition, there is a method of enhancing the durability by the structure of the sprocket and the chain when the strong force is applied for the transmission of the accurate rotation, which is also the same configuration as the structure of the belt and the belt pulley.

A center shaft coupling portion 137 for coupling the end of the center shaft 12 and the end of each mounting shaft 111 is formed at the end of the center shaft 12, And a mounting shaft coupling portion 138 for coupling with the end portion of the center shaft 12 is formed and the center shaft coupling portion 137 and each mounting shaft coupling portion 138 are coupled by a coupling arm 139, The central shaft coupling part 137 may be configured such that the connection arms 139 are gathered and rotatable.

FIG. 3 is a conceptual view showing a trajectory of a wing according to an embodiment of the present invention. FIG. 4 is a schematic view showing the operation of a wing at each position according to an embodiment of the present invention, Shows the locus formed when the main body 11 makes one revolution, and the locus of all the wings 112 has the same locus as shown.

The movement of the main body 11 can be easily explained with the same concept as the ship's oars. In the position where the wing 112 is perpendicular to the tangential line, the fluid is pushed to push the fluid from right to left, The driving force acts in the same direction due to the vector sum of the wings while the angle of the wing 112 changes with the rotation of the wing 112. The resistance is minimized at the position where the wing 112 is parallel to the tangential line, Is zero.

Therefore, considering the interference between the wings 112, the number of the wings 112 may vary depending on the size, but it may be said that three to eight wings 112 are suitable. When all the wings 112 are the same It is most important to adjust it to have a trajectory.

In addition, as described above, it is preferable to have a structure of a timing belt or a chain so that the locus does not change due to slipping or flow during operation.

In order to adjust the direction, the center shaft 12 is connected to the center shaft 12, and the direction changing unit 121 for rotating the center shaft 12 at a predetermined angle to change the direction of the driving force is mounted When the central axis 12 is turned by the direction switching means 121, the absolute position of the above-mentioned locus is changed and the direction of rotation is switched.

As shown in the figure, the direction changing unit is formed as a simple handle and can be rotated by a mechanical force such as a central shaft 12, a hydraulic device, or the like. have.

If the principle of direction change of the present invention is applied to an existing ship, in order to reverse the conventional ship, the engine is stopped and the screw is rotated in the opposite direction. However, the present invention is solved by turning the center shaft 12, There is an advantage that various motions can be performed because it can not be relied upon.

In particular, in the past, it is easier to bend a large-sized ship which is dull in movement, and it is possible to move more delicately when applied to a towing ship. In case of applying to a submarine, the noise generated from a conventional screw can be drastically reduced, You will be able to increase your sex.

Also, it can be applied to fans and fans. It has quietness due to low vibration and noise, and it has various advantages that it can have high output compared to the number of revolutions.

5 is a conceptual diagram according to another embodiment of the present invention. The interlocking means 13 includes a first interlocking gear 134 mounted on the center shaft 12, a mounting shaft 111 of the wing 112, A second interlocking gear 135 mounted on the first interlocking gear 134 and having gears two times larger than the gears of the first interlocking gear 134 and a second interlocking gear 135 meshing with the first and second interlocking gears 134, (136). In the example of FIG.

In this embodiment, the center shaft 12 and the blades 112 should be rotated in the same direction, and if the rotation by the gear is transmitted, the follower gear 136 must be provided in the middle to rotate in the opposite direction.

Therefore, a driven gear 136 connected to each of the second interlocking gears 135 may be provided. However, in the drawing, the number of the driven gears 136 can be reduced by interlocking with the two adjacent second interlocking gears 135 And the like.

Such a method is easy to apply to a device for relatively small airflow, and conversely, even when a strong force is transmitted, the gear method has high durability.
