BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation system of a ship using a gyroscope principle, and more particularly, to a power generation system of a ship using a gyroscope principle, So that the power generation efficiency can be improved.

Generally, a gyro-stabilizer is a device for stabilizing the hull with a reaction torque generated by the precession of a gyroscope. The gyro-stabilizer is simpler than other rolling- Configuration.

In addition, since the reaction torque can be proportional to the rotation inertia of the gyro and the rotation speed of the gyro, it is possible to stabilize the posture of the ship, and it is possible to control the posture of the ship through the large equipment such as ballast water, It can be said that it is advantageous for a ship or the like.

As one of related prior arts, Japanese Patent Application Laid-Open No. 10-2016-0042600 discloses a power generation system for a ship using a gyroscope principle.

1 is a view showing a power generation system of a ship using a conventional gyroscope principle. 1, when the ship is rolling, the power can be supplied to the ship by using the pitch axis of the hull as an output shaft and the torque of the output shaft to generate electricity. In addition, when pitching occurs in the hull, And the like.

A power generation system using the conventional gyroscope principle will be described in detail. The power generation system includes a block 110 fixed to a hull of a ship, a luggage compartment 121 rotatably coupled to both sides of the block 110, A flywheel 130 which is rotatably installed inside the gimbals 120 and is pivotally moved about a center axis in a direction orthogonal to the gimbal axis 121 and the flywheel 130, And a drive motor 140 coupled to a center axis of the flywheel 130 to rotate the flywheel 130. The central axis of the flywheel 130 is arranged coincident with the yaw axis of the hull, And the generator 200 is fixed to the end of each of the load balancing shafts 121. When rolling or pitching occurs in the hull, the power is generated by the rotation of the load balancer 121. [

However, in the case of a ship power generation system using the above-described conventional gyroscope principle, the car wash direction has rotational motion in the forward and reverse directions, and as a result, the generator changes the rotational direction continuously along the gimbals, A large fatigue load is applied to the load balancer connecting the parts, and a low angular velocity generated in the course of changing the direction causes a problem that the power generation efficiency of the generator is lowered.

In addition, since the generator is arranged on both sides of the gyro stabilizer, there arises a problem that the volume of the system is large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gyro stabilizer which is provided in a ship and is capable of rotating the generator shaft only in one direction when performing power generation using rotation of the output shaft of a gyro stabilizer, To the system.

In order to solve the above-mentioned problems, a power generation system of a ship using a gyroscope principle according to an embodiment of the present invention includes a block fixed to a hull of a ship, a gimbal having a lowering shank coupled to both sides of the block, A gyro stabilizer comprising a flywheel rotatably installed in the interior of the gimbals, the flywheel having a central axis in a direction orthogonal to the gimbals, and a drive motor capable of rotating the flywheel; A generator shaft having a generator shaft interconnected with the load balancer and a first clutch bearing; And a rotary transducer connected between the gyro stabilizer and the generator to convert rotation of both sides of the gyro stabilizer to the generator in one direction, and to transmit the rotation to the generator, wherein the rotation of the gyro stabilizer causes rotation of the generator shaft in one direction Power generation can be performed.

The rotary converter includes a first bevel gear engaged with the load balancer, a second bevel gear interconnected with the generator shaft and the second clutch bearing, and a second bevel gear interposed between the first bevel gear and the second bevel gear, And a third bevel gear interconnecting the two bevel gears.

According to the embodiment of the present invention, the following effects are expected.

First, there is an effect that the power generation efficiency can be improved by providing a rotary converter for maintaining the rotation direction of the generator in one direction between the gyro stabilizer and the generator at the time of power generation by using the gyro stabilizer.

In addition, since the fatigue load applied to the gyro bellows of the gyro stabilizer is greatly reduced, both the gyro stabilizer and the generator have high durability against repeated loads, thereby significantly extending the service life of the system.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, the present invention is based on the principle of a gyroscope for a ship in which a ship stabilizing device such as a bilge keel, an anti-rolling tank and a fin stabilizer is difficult to install, The present invention is intended to construct a power generation system by using a gyro-stabilizer that suppresses the fluctuation of the power source.

FIG. 2 is a view showing a power generation system of a ship using the principle of gyroscope according to the present invention, and FIG. 3 is a view showing a gyro stabilizer according to the present invention. As shown in the figure, the power generation system according to the embodiment of the present invention includes a gyro stabilizer 10, a generator 20, and a rotary converter 30 positioned between the gyro stabilizer 10 and the generator 20 do.

3, the gyro stabilizer 10 includes a block 11, a gimbal 12, a flywheel 13, and a drive motor (not shown) 14).

Here, the block 11 is for fixing the gyro stabilizer 10 to the hull of the ship.

The gimbal 12 is rotatably mounted on the gimbal shaft 15 by forming a gimbal shaft 15 rotatably coupled to both sides of the block 11. A support member hinged to the load reduction shaft 15 is provided on both sides of the block 11 so that the gimbals 12 can be pivoted. As shown in Fig.

Next, the flywheel 13 is rotatably installed inside the gimbal 12, and the flywheel 13 is pivoted about a central axis in a direction orthogonal to the load-down shaft 15. The motor 14 allows the flywheel 13 to rotate.

In the gyro stabilizer 10 constructed as described above, the central axis of the flywheel 13 corresponds to the spin axis of the gyroscopic principle, which is arranged coincident with the yaw axis z of the hull. The load balancer 15 corresponds to the output axis of the gyroscopic principle arranged to coincide with the pitching axis y of the hull. Here, when the generator 20 is fixedly installed on one side of the load balancer 15 and the rolling or pitching of the ship body occurs, the rotation of the gimbals 12, that is, the rotation of the load balancer 15 as the output shaft, .

When the flywheel 13 that is rotated by the drive motor 14 is subjected to rolling, a pitching moment acts on the flywheel 13 and the gimbals 12 to rotate the losing bulb 15, Generator 20 to perform power generation. Further, when pitching occurs in the hull, the load balancer 15, which is an output shaft, is rotated to transmit the rotational driving force to the generator 20 to perform power generation.

In other words, when rolling occurs in the hull and the drive motor 14 rotates the flywheel 13, a moment is generated in the load reduction shaft 15, which is an output shaft, in order to reduce rolling, so that the load reduction shaft 15 rotates In addition, when pitching is applied to the hull, the rotational force of the load balancer 15 is further increased, thereby realizing an energy havesting system capable of performing power generation using an unstable attitude of the hull due to wave power .

4 is a cross-sectional view of a rotary transducer according to the present invention.

According to the present invention, a rotary transducer 30 is provided between the gyro stabilizer 10 and the generator 20, as shown in FIG.

First, the one load balancer shaft 15 and the generator shaft 21 are connected to each other through the first clutch bearing 16.

Here, the first clutch bearing 16 according to the present invention refers to a kind of one-way bearing that transmits only the rotational force in one direction and does not transmit the rotational force in the opposite direction.

That is, as shown in the figure, when the load balancer 15 is rotated in the reverse direction (counterclockwise about the gimbals shaft), the generator shaft 21 is also rotated in the reverse direction by the first clutch bearing 16, When the first clutch 15 is rotated in the normal direction (clockwise around the gimbals shaft), the first clutch bearing 16 is not connected to the generator shaft 21, so that the generator shaft 21 is not rotated.

In order to keep the power generator shaft 21 continuously rotated in the reverse direction even when the load balancer 15 rotates in the forward direction (clockwise around the gimbals shaft), the rotation converter 30 according to the present invention as shown in FIG. .

The rotary converter 30 includes a first bevel gear 31 and a second bevel gear 32 and a third bevel gear 33 interconnecting the first bevel gear 31 and the second bevel gear 32, And a second clutch bearing (34) connecting the first and second clutch bearings (21, 21).

The first bevel gear 31 is engaged with and coupled to the one of the load balancers 15 and the second bevel gear 32 is connected to the generator shaft 21 through the second clutch bearing 34. [ And the third bevel gear 33 is connected to the first bevel gear 31 and the second bevel gear 32 by a central axis in a direction orthogonal to the load balancer 15 to transmit rotational force do.

At this time, the second clutch bearing (34) is installed to transmit rotational force only in the same direction as the first clutch bearing (16). In order to facilitate understanding, the present invention can not transmit rotational force in the forward direction And the rotational force is transmitted when the motor rotates only.

With the rotary converter 30 of the present invention, the power generator shaft 21 can be continuously rotated only in the reverse direction irrespective of the rotational direction of the load shaft 15, which will be described in more detail as follows.

First, when the load balancer 15 is rotated in the reverse direction, the generator shaft 21 is also rotated in the opposite direction through the first clutch bearing 16. The first bevel gear 31 coupled to the first bevel gear 31 rotates in the opposite direction as a result of the reverse rotation of the load balancer 15 and consequently the second bevel gear 32 is rotated by the third bevel gear 33 in the opposite direction Rotation. Since the second clutch bearing 34 connecting the second bevel gear 32 and the generator shaft 21 transmits the rotational force only in the opposite direction, the connection is disengaged in the forward direction and the rotational force can not be transmitted. Therefore, The rotational force of the generator shaft 15 is transmitted to the generator shaft 21 through the first clutch bearing 16 and the generator shaft 21 is rotated in the reverse direction.

When the first clutch bearing 16 is rotated in the forward direction, only the reverse rotation force is transmitted to the first clutch bearing 16, so that the connection is disengaged in the forward direction and the first clutch bearing 16 is engaged with the power generator shaft 21 through the first clutch bearing 16, But the first bevel gear 31 coupled to the first bevel gear 31 rotates in a forward direction as a result of the forward rotation of the luggage compartment shaft 15. As a result, the second bevel gear 33 is rotated by the third bevel gear 33, (32) rotate in the opposite direction. As a result, the second clutch bearing (34) connecting the second bevel gear (32) and the generator shaft (21) transmits the rotational force in the opposite direction, so that the generator shaft (21) also rotates in the reverse direction.

Therefore, the generator shaft 21 can be continuously rotated only in the reverse direction irrespective of the direction of rotation, that is, the forward direction or the reverse direction of the load reduction shaft 15, which is very efficient in terms of utilizing the rotary inertia of the generator. As the generator axis always rotates in the same direction, even if the angle of the car motion is small, there is an advantage that the generator does not stop, but the electricity can be produced by the rotation by the inertia.

As described above, the basic technical idea of the present invention is to provide a power generation system of a ship using a gyroscope principle capable of increasing power generation efficiency by rotating the generator shaft in one direction irrespective of the rotation direction of the gypsum shaft of the gyro stabilizer provided in the hull of a ship It can be seen that
