Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a power generation module according to a first embodiment of the present invention.

Fig. 1 is a configuration diagram showing an embodiment of a power generation module using vessel fluctuation according to the present invention, Fig. 2 is a view for explaining the operation of Fig. 1, Fig. 3 is a diagram specifically explaining a pedestal shown in Fig. 1 to be.

Referring to FIG. 1, a power generation module A using a ship sway includes a pivot 100 and a generator 200.

The rotary shaft 100 is fixed to the hull SB so as to rotate in response to the wobble of the ship due to an external force as shown in Fig. 2 and is fixed to the upper part of the hull 110 fixed to the hull SB .

The generator 200 is configured to convert the rotation of the rotary shaft 100 into electric energy and to be independent of the sway of the ship SB so as to maintain the rotation stopped with respect to the gravity direction.

In other words, the generator 200 can be installed so that the hull SB can always maintain a constant state even if it is shaken.

More specifically, the generator 200 includes a generator motor 210 that converts the rotation of the rotary shaft 100 into electric energy using the rotary shaft 100 as a motor shaft 211 as shown in FIG. 1 .

The rotating shaft 100 formed in the direction opposite to the motor shaft 211 can be coupled to the generator 200 so as to be rotatable by the bearing B as shown in FIG.

Therefore, even if the hull SB fluctuates as shown in Fig. 2, the generator 200 can maintain a constant state.

In addition, the power generation module (A) using the shaking motion of the present invention can constitute the pedestal 300 so that the generator 200 can maintain a stable state when the ship is shaking.

The pedestal 300 may be fixed to the hull SB as shown in FIGS. 1 to 3 and may have a curved seating part 310 where the generator 200 is placed.

The generator 200 has a wheel-shaped leg 220 at a lower portion thereof, and can reciprocate along the curved surface of the seat 310, as shown in FIG.

As a result, the kinetic energy due to the shaking motion of the ship can be regarded as rotational energy centered on the rotary shaft 100.

Therefore, it is preferable that the seating part 310 of the pedestal 300 is formed as a curved surface corresponding to an arc centering on the pivotal axis 100.

3, a guide groove 311 for guiding the movement of the wheel-shaped leg 220 may be formed on the seat 310 of the pedestal 300.

Fig. 4 is a configuration diagram showing another embodiment of a power generation module using ship fluctuation according to the present invention, and Fig. 5 is a view for explaining the operation of Fig.

Referring to FIG. 4, the power generation module A using the shaking motion includes a rotary shaft 100, a power generator 210, and a gear box 400.

The rotary shaft 100 is fixed to the hull, one end of which is fixed to the hull, and the other end of which is connected to the gear box 400. 4, the pivot shaft 100 may be fixed to the base panel 510 fixed to the hull, or may be fixed directly to the hull.

The power generation motor 210 is installed such that the motor shaft 211 is rotatable with respect to the hull, and keeps the rotation stopped in the direction of gravity. Of course, it is needless to say that the power generation motor 210 can be fixed to the base panel 510 fixedly installed on the hull, in the same way as or similar to the rotary shaft 100.

The power generating motor 210 may be pivotally coupled to a support 213 fixed to the hull or the base panel 510.

For example, as shown in Fig. 4, the power generation motor 210 may be rotatably coupled to the support 213 by means of a bearing (B).

Meanwhile, at least one mass body 212 may be formed in the downward direction in order to keep the power generation motor 210 in a constant state regardless of the yawing motion.

Therefore, the power generation motor 210 can continuously maintain the rotation stopped state with respect to the gravity direction (downward direction in Fig. 4) by the mass body 212. [

For this purpose, the power generation motor 210 may be disposed at a position spaced from the hull or the base panel 510 by a support 213 as shown in FIG.

The gear box 400 amplifies the rotation angle of the rotation shaft 100 and transmits the amplified rotation angle to the motor shaft 211 of the power generation motor 210. The rotation shaft 100 is connected to the start shaft 410, And the motor shaft 211 may be a slave shaft 420.

In consideration of the fact that the rotation angle due to ship sway does not deviate from a certain range, the gear box 400 is configured to rotate the rotation shaft 100 in the rotation amount corresponding to the minimum rotation speed at which the power generation motor 210 can generate power . Here, the gear ratio and the internal structure of the gear box 400 may be variously changed according to the needs of those skilled in the art, and the present invention is not limited thereto.

5, the structure of the rotary shaft 100 and the generator motor 210 may be configured in the housing 500 for a power module.

5, when the housing 500 for a power module is pivoted (indicated by a solid line arrow in FIG. 5), the effect of rotating the motor shaft 211 with respect to the housing 500 for the power module Arrows).

As a result, the starting shaft 410 and the driven shaft 420 of the gear box 400, which are amplified by the gear ratio of one side and transmitted by the rotational force of the other side, are fixed to the hull (precisely, And the motor shaft 211 independently provided independently of the shaking motion of the hull is connected to each other to improve the power generation efficiency of the power generation motor 210. [

FIG. 6 is a configuration diagram showing another embodiment of the power generation module using ship fluctuation according to the present invention, and FIG. 7 is a view for explaining the operation of FIG.

Referring to FIG. 6, the power generation module A using the shaking motion may include a rotary shaft 100, a power generation motor 210, and a gear box 400.

The rotating shaft 100 is installed on the hull so as to maintain the rotation stopped with respect to the direction of gravity. As shown in Figs. 6 and 7, the rotating shaft 100 is rotated in the downward direction At least one mass body 212 may be constructed.

The pivot shaft 100 can be pivotally coupled to the support 213 by a bearing B while being disposed at a position spaced a predetermined distance from the hull by a support 213 fixed to the hull.

The power generation motor 210 is fixed to the hull, and can be fixedly installed by a separate fixed table (not shown) as shown in Fig.

The gear box 400 amplifies the rotation angle of the rotation shaft 100 and transmits the amplified rotation angle to the motor shaft 211 of the power generation motor 210.

As a result, as shown in FIG. 7, when the housing 500 for a power module is pivoted (solid line arrow in FIG. 7) due to vessel fluctuation, the effect of rotating the motor shaft 211 with respect to the housing 500 for power generation module (Boxed arrow in Fig. 7).

When the rotation angle of the rotation shaft 100 is transmitted to the start shaft 410, the rotation angle is amplified to a sufficient amount of rotation for power generation and is transmitted to the motor shaft 210 of the generator motor 210 through the follower shaft 420 0.0 > 211 < / RTI >

On the other hand, in the case of the AC power generating motor 210, it is possible to produce electrical energy regardless of the direction of rotation, but in order to use it for various facilities, it must be converted to DC.

Therefore, in this embodiment, the motor shaft 211 of the power generation motor 210 rotates in a constant direction irrespective of the rotation direction of the ship sway, so that the direct electric energy can be directly produced, and the AC / And the like can be minimized.

Hereinafter, a method of switching the bidirectional rotation of the rotary shaft 100 to one direction and transmitting it to the motor shaft 211 will be described.

8 to 10 are views for explaining a gear structure inside the gear box in which the motor shaft shown in FIG. 1 is rotated only in one direction.

Specifically, Fig. 9 illustrates the operation of the first unidirectional gear 430 shown in Fig. 8A. Fig. 10 shows the operation of the second unidirectional gear 440 shown in Fig. 8B It is explained.

8, the gear box 400 is provided with a first unidirectional gear 430 for rotating the motor shaft 211 in the same direction as the rotating shaft 100 and a second unidirectional gear 430 for rotating the motor shaft 2110 along the rotating shaft 100. [ The second unidirectional gear 440 can be configured to rotate in the opposite direction.

9, the gear box 400 is provided with a first gear 450 to which the first unidirectional gear 430 is meshed inward and a second gear 450 to be meshed with the second unidirectional gear 440 And the second gear 460 is gear-engaged at the outside.

In other words, the inner gear 451 formed inside the first gear 450 and the first unidirectional gear 430 can be gear-engaged, and the outer gear 461 formed outside the second gear 460 The second unidirectional gear 420 can be gear-engaged.

First, as shown in FIG. 9A, the first gear 450, which receives the rotational direction of the rotating shaft 100, receives the first gear 450 and the second gear 450, When the first unidirectional gear 430 rotates counterclockwise, the driven shaft 420 connected to the first unidirectional gear 430 does not rotate.

9 (b), when the first gear 450 rotates clockwise, the first gear 450 and the first unidirectional gear 430 are engaged with each other and the first unidirectional gear 430 The driven slave shaft 420 can be rotated clockwise.

In other words, the first unidirectional gear 430 can be rotated in one direction (clockwise direction) when the first gear 450 rotates in one direction (clockwise), and the first gear 450 can be rotated in the other direction (Counterclockwise) in the direction of rotation.

Next, the operation of the second unidirectional gear 440 and the second gear 460 will be described. As shown in FIG. 10 (a), the second gear 460, which receives the rotation direction of the rotation shaft 100, The second gear 460 and the second unidirectional gear 440 are engaged with each other and the driven shaft 420 connected to the first unidirectional gear 430 is rotated in the clockwise direction.

10 (b), when the second gear 460 rotates in the clockwise direction, the second unidirectional gear 440 loosens and the driven shaft 420 connected to the second unidirectional gear 440 rotates clockwise, Do not rotate.

In other words, the second unidirectional gear 440 can be rotated in one direction (clockwise direction) when the second gear 460 rotates in the other one direction (counterclockwise direction) It may not rotate when it rotates in one direction (clockwise direction).

Therefore, the motor shaft 211 can be rotated in a predetermined direction through the first unidirectional gear 430 and the second unidirectional gear 440 regardless of the direction of rotation of the rotating shaft 100. [

In FIG. 8, reference numerals 431 'and 441' denote fitting protrusions which are fitted to the vertical axis 420.

In addition, in the marine power generation system of the present invention, the power generation module (A) using the above-described ship wobble is used as a unit generation module, and a plurality of unit generation modules are arranged in a clearance space inside the ship, A larger amount of electric energy can be produced.

In addition, according to the rotation direction of the power generation module (A), it is possible to convert the rotational energy generated by the longitudinal oscillation to the electric energy as well as the lateral oscillation of the ship.

On the other hand, most of the fluctuations of the ship occur in a complex manner, not in one of them independently.

Thus, it is possible to use the horizontal motion and the longitudinal motion simultaneously as follows.

11 is a view for explaining an embodiment of a power generation module to be constituted in a marine power generation system according to the present invention.

Referring to FIG. 11, the power generation module A using the above-described shaking motion is constituted by a unit power generation module, and the rotation directions of the power generation modules A are orthogonal to each other, Can be converted into electrical energy.

More specifically, at least one of the rotation axis and the motor axis of one unit generation module (first unit generation module) and the other unit generation module (second unit generation module) is arranged to be orthogonal to each other, The first unit generating module and the second unit generating module are electrically connected to each other so that the rotational energy of the ship as well as the swaying of the ship can be used as electric energy.
