Hereinafter, with reference to the accompanying drawings to describe the specific content for the practice of the present invention.

1 is a view showing the configuration of a wave power generating apparatus according to an embodiment of the present invention.

The wave power generation apparatus according to an embodiment of the present invention includes a gyroscope energy conversion device 110 for converting wave energy into electrical energy and a variable water column vibration device 200 for maximizing the absorption of wave energy.

To describe each configuration in detail, the gyroscope energy converter 110 is connected to the electric motor 112, the flywheel 111 having an angular momentum, the motor 112 for supplying rotational force to the flywheel 111, the blue pitching motion Torque drive 113 for transmitting the torque generated by the change of the angular momentum of the flywheel by the hydraulic cylinder (116a, 116b), is connected to the surface of the torque drive 113 by a joint (joint), and transmitted from the torque drive 113 Hydraulic cylinders 116a and 116b for converting the torque into hydraulic pressure.

For reference, the torque drive unit 113 is connected to the torque connection drive unit 114b, and the torque connection drive unit 114b is connected to the horizontal axis 114a so that the horizontal axis 114a, the torque connection drive unit 114b, and the torque drive unit 113 are provided. Can be integrated.

Therefore, when the horizontal shaft 114a is rotated while being supported by the bearing 115, the torque drive unit 113 pendulum moves in the direction of the arrow indicated on the horizontal shaft 114a in accordance with the rotation of the horizontal shaft 114a.

In more detail, the electric motor 112 supplies a rotational force to the flywheel 111 (clockwise in FIG. 1) in order to obtain a large torque for the blue pitching motion.

Although will be described in detail with reference to FIG. 2, the flywheel 111 may have an angular momentum through the rotational force supplied from the electric motor 112.

Subsequently, when the pitching motion of the blue occurs, the blue energy is absorbed (maximized) through the variable column oscillation apparatus 200, and through this, the torque generated by the change in the angular momentum is generated in the flywheel rotated by the electric motor 112. Done.

Due to the generated torque, the torque drive unit 113 pendulum moves in the direction indicated by the arrow on the horizontal axis 114a, and the hydraulic cylinders 116a and 116b jointly connected to the surface of the torque drive unit 113 are torque drive units ( The fluid may be compressed according to the pendulum motion of 113).

That is, when the potential energy is minimum in the pendulum motion of the torque drive unit 113, the hydraulic cylinders 116a and 116b compress the fluid in the cylinder to the maximum, and the maximum potential energy is increased in the pendulum motion of the torque drive unit 113. In this case, the interior of the hydraulic cylinders 116a and 116b will expand to the maximum.

Figure showing the torque generated when tilted at a speed and the force acting on the hydraulic cylinder.

The flywheel 111 is rotated clockwise by the angular velocity ω _o by the motor 112, wherein the angular momentum of the flywheel 111 is L ₀ (Iω _o ).

속도로 기울어지면, 이때 발생하는 토크는 τ=L₀·Ω 가 되며, 이를 벡터 형태로 변환하면 τ=Ω×L₀ 가 된다.If, by blue, variable water body

When inclined at a speed, the torque generated at this time becomes τ = L ₀ · Ω, which is converted into a vector form τ = Ω × L ₀ .

Therefore, the force F acting on the hydraulic cylinders 116a and 116b becomes a value obtained by dividing the distance component in the torque amount and the direction of the force is the opposite direction of the X axis.

Therefore, if the pitching movement of the blue proceeds in the Y-axis and -Y-axis directions, torque is generated in the X-axis and -X-axis in the torque drive unit 113 including the electric motor 112 and the flywheel 111. Due to the torque drive 113 is pendulum movement.

This force drives the hydraulic cylinders 116a and 116b and generates oil pressure, and the generated oil pressure supplies a rotational force to the hydraulic motor, and the generator 126 can convert the rotational force of the hydraulic motor 123 into electricity.

At this time, the generator 126 output W is proportional to the angular velocity dθ / dt due to the pitching of the blue wave.

3 is a view showing the configuration of the variable order vibration device 200 according to an embodiment of the present invention.

For reference, the variable column oscillation apparatus 200 illustrated in FIG. 3 may operate in conjunction with the upper or lower portion of the gyroscope energy conversion apparatus 110 illustrated in FIG. 1.

Variable order vibration device 200 according to an embodiment of the present invention is a plurality of vertical pipes 212a, 212b (hereinafter, the first vertical pipe (2) communicating with each other through a horizontal pipe 211 and a horizontal pipe 211) 212a), a U-shaped conduit 213 composed of a second vertical conduit 212b, and a plurality of air chambers connected to the plurality of vertical conduits 212a and 212b and isolated from each other about the separator 214. 215a and 215b (hereinafter also referred to as first air chamber 215a and second air chamber 215b) and air control valves 216a and 216b respectively disposed in the plurality of air chambers 215a and 215b. A plurality of pressure control valves 222a, 222b, and 222c disposed between the variable water main body 210, the air line 221 connecting the plurality of air chambers 215a and 215b, and the air line 221. Ship to any one of the plurality of pressure sensors 223a, 223b and the plurality of vertical conduits 212a, 212b disposed between the air in the air chambers 215a, 215b. Level sensor 224 and the aforementioned air control valves 216a and 216b, pressure control valves 222a, 222b and 222c, pressure sensors 223a and 223b, and a controller 225 connected to the water level sensor 224. ).

In describing the components, the pressure sensors 223a and 223b measure the pressure in the air chambers 215a and 215b and convert the measured pressure values into currents or voltages corresponding to the measured pressure values.

In addition, the water level sensor 224 measures the water level of the U-shaped pipe 213, and converts the measured water level value into a current or voltage corresponding to the value of the measured water level.

For reference, the pressure and level conversion values of the pressure sensors 223a and 223b and the water level sensor 224 may be input to the controller 225 to be used for driving the wave power generator.

On the other hand, the horizontal pipeline 211 is filled with the internal working fluid 230, which is a certain amount of water or seawater, and the air spring constant generated from the mass of the internal working fluid 230 and the air filled in the air chambers 215a and 215b. Can form a vibrometer.

In addition, when a force is applied from the above-mentioned blue wave of the vibrometer, the inner working fluid 230 flows, and the flow of the inner working fluid 230 causes the air filled in the air chambers 215a and 215b to compress or expand. do.

In the present invention, the air spring constant of the air filled in the air chambers (215a, 215b) can be adjusted using the air control valves (216a, 216b) in order to synchronize the vibration of the variable water column oscillation device (200) in the period of blue. have.

On the other hand, the controller 225 is a variable water body 210 according to the amplitude (height) and period of the blue input from the outside through an external device such as a crest meter (not shown) with a separate sensor as shown in Figure 4 from there to a control air pressure (P _o) of the state of equilibrium of the air chamber (215a, 215b) to improve the energy absorbing efficiency when tilted by θ.

In addition, the controller 225 may include the pressure control valves 222a, 222b, and 222c disposed between the air ducts 221 connecting the air chambers 215a and 215b according to the amplitude and period of the blue color. The energy absorption efficiency may be improved by opening and closing at a specific water level Z _s .

Here, when the pressure control valves 222a, 222b, and 222c are opened and closed based on the specific water level Z _s , a nonlinear air spring constant may be obtained according to the set value of the specific water level.

Since the air spring constants form the mass and vibrometer of the internal working system, if a certain water level (Z _s ) is set properly in consideration of the period and amplitude of the blue, the energy of the variable water column vibration device 200 is oscillated to be synchronized with the period of the blue energy. Absorption rate can be improved.

For reference, the specific water level Z _s may be obtained from an equation or a look-up table which functions as a function of the period and amplitude of the blue wave.

In addition, the controller 225 may reduce the excessive load applied from the extreme wave by controlling the air pressure in the air chambers 215a and 215b when an extreme wave occurs.

Here, the extreme wave means a huge wave that occurs at a cycle of more than 100 years, and this huge wave generates an excessive load on the wave power generator, thereby increasing the probability of failure.

On the other hand, the U-shaped pipe 213 is filled with a predetermined amount of the internal working fluid 230, the internal working fluid 230 may use water or sea water.

4 is a view for explaining a method of synchronizing the natural vibration period of the variable column vibration apparatus 200 according to an embodiment of the present invention to the period of the blue.

In the state in which the valve 222b located at the center of the plurality of pressure control valves 222a, 222b, and 222c is closed, and in equilibrium state using the remaining valves 222a and 222c directly connected to the air chambers 215a and 215b. of the air chamber (215a, 215b) air pressure (P _o) the valves of the remaining two sides of the exception of the valve (222b) in the center the first control scheme, a plurality of pressure control valves (222a, 222b, 222c) for controlling the ( With the 222a, 222c closed, there is a second control scheme that non-linearly controls the pressure in the air chambers 215a, 215b using a centrally located valve 222b.

Both of these control methods induce a spring effect caused by the contracted expansion of the air, thereby controlling the natural vibration cycle of the variable column vibration device 200 applied to the present invention.

First, a linear to a first pressure of controlled air chamber (215a, 215b) in the equilibrium amount of change in the air volume due to water level variations in the spring constant of the air spring is inside the hydraulic fluid (230) according to (P _o) enemy Proportional to

Therefore, when the air chambers 215a and 215b are completely vacuum, the spring constant becomes 0. As the pressure increases, the spring constant becomes larger.

Accordingly, the equilibrium in air pressure in the air chamber _{(215a, 215b) (P o} ) is adjustable without the need for compression pump or vacuum pump by a pressure control valve (222a, 222b, 222c).

For example, when the pressure in the air chambers 215a and 215b rises above atmospheric pressure due to the induction of the internal hydraulic fluid 320 of the variable water main body 210, the controller 225 may be configured to control some of the pressure control valves 222a and 222c. It is possible to release a predetermined amount of air to the atmosphere by opening the through, it is possible to maintain the air pressure (P _o ) of the air chamber (215a, 215b) in an equilibrium state lower than the atmospheric pressure.

In contrast, when air pressure in the air chamber (215a, 215b) at equilibrium (P _o) is lower than the atmospheric pressure, the controller 225 opens the part (222a, 222c) of the pressure control valve to ensure that the air is sucked in through the air In this way, the air pressure of the air chambers 215a and 215b may be maintained higher than atmospheric pressure.

In the second control method, the valve 222b located in the center of the pressure control valve may be opened and closed only for a specific condition according to the level of the internal working liquid 320 to effectively induce the effect of the air spring.

That is, if the water level of the internal working fluid 320 in the vertical pipe lines 212a and 212b rises or falls above the set specific water level Z _s , the controller 225 may move the pressure control valve 216b in the center. By closing the inner working fluid 320 can compress or expand the air in the air chamber (215a, 215b) by the force of inertia, thereby causing the effect of the air spring.

For example, as shown in FIG. 4, when all of the pressure control valves 222a, 222b, and 222c are closed in a state where the variable water body 210 is rotated at an angle by the blue of the sea water, the first vertical The inner working fluid 320 tank of the conduit 212a compresses the air of the first air chamber 215a, and the inner working fluid 320 water tank of the second vertical conduit 212b of the second air chamber 215b. Since the air is expanded, the level of the internal working liquid 320 is generated to restore the position to the position before the centrally located pressure control valve 222b is closed.

However, in the region where the level of the internal hydraulic fluid 320 does not exceed the set specific level Z _s , since the centrally located pressure control valve 222b is open, it does not cause the air spring effect, so that the internal hydraulic fluid ( 320 is free to move the U-shaped conduit 213 without being constrained.

On the other hand, the amplitude and period of the blue can be input from an external device such as a crest meter (not shown) having a separate sensor as described above.

The present invention is generated by the second control method of controlling the first control method and the pressure of the air chamber (215a, 215b) for controlling the air pressure (P _o) of the air chamber (215a, 215b) in a state of equilibrium in a non-linear By using the air spring effect, the air spring effect constitutes a vibrometer together with the mass of the internal working fluid 320, thereby maximizing energy absorption efficiency by synchronizing the vibration characteristic of the wave power generator to the blue vibration cycle. Can be.

In the output operation, the above-described first and second air pressure in the air chamber (215a, 215b) to absorb the maximum energy from the period and amplitude of a given blue in accordance with the control scheme (P _o) and a viscosity coefficient of friction or a certain limit, set and After obtaining the viscous friction coefficient, the controller 225 may apply these control variables by scheduling them according to the amplitude and period of the blue wave.

5 is a diagram illustrating a gyroscope energy conversion device 110 according to another embodiment of the present invention.

FIG. 5 illustrates a case in which a plurality of gyroscope energy converters 110 are installed in the wave power generator. When only one gyroscope energy converter 110 is installed, the gyroscope energy converter 110 is inclined to one side. The variable water column 210 may be inclined to one side and thus become unstable.

In order to compensate for this disadvantage, one more gyroscope energy converter 110 'may be installed, and the flywheels rotate in opposite directions.

Torque forces generated from the flywheel are reversed by the wave pitching, so that the variable water main body 210 of the wave power generator can be balanced, and there is an advantage of converting the input wave energy into more electric energy. .

6 is a flowchart illustrating a process of converting a wave motion into an electrical output by the wave power generator according to an embodiment of the present invention.

First, the gyroscope energy converter 110 acquires information on the amplitude and the period of the blue wave to maximize the absorption of the blue energy and transmits the information to the variable water column oscillator 200 (S601).

After S601, the variable water column vibration device 200 changes the natural vibration characteristic of the variable water body 210 so that the variable water body 210 is tuned to the period and amplitude of the blue water (S602).

After S602, the variable water column 210 is resonated to maximize pitching, which is a movement in the Y-axis direction (S603).

After S603, in the gyroscope energy converter 110, as the rotational angular velocity is generated in the variable water body 210, a change occurs in the angular momentum of the flywheel 111, and a torque is generated to act on the hydraulic cylinder (S604). .

For reference, in the gyroscope energy converter 110, the electric motor 112 supplies a rotational force to the flywheel 112, in order to obtain a large torque against the blue pitching motion. The greater the supply of rotational force, the greater the torque can be generated.

After S604, this force generates the hydraulic pressure, the hydraulic pressure is generated by rotating the rotor of the generator (S605).

7 is a graph illustrating control frequency response characteristics according to a first control method according to an embodiment of the present invention.

An air chamber (215a, 215b) air pressure (P _o), the larger the more the tuning order damper (Tuned Liquid Column Damper, TLCD quot;) region is formed in the short blue cycle air pressure according to the blue period (P _o of at equilibrium ), The response of the present invention by the first control scheme is always larger than the response of the extreme wave condition.

8 is a graph illustrating control frequency response characteristics according to a second control method according to an embodiment of the present invention.

This is because the TLCD region does not move as in the control frequency response of the first control scheme, but as the specific reference level Z _s of the vertical pipes 212a and 212b increases, the response amplitude increases in a short wave period. have.

Therefore, by properly adjusting the specific reference level Z _s set according to the wave period, the response of the present invention by the second method can be always larger than the response of the extreme wave state.

In the first control method described above was defined air pressure (P _o) of the air chamber (215a, 215b) when in the state of equilibrium as a control parameter, the second control method, in accordance with the level of internal working fluid 320, as the control variable, The set specific reference water level Z _s of the vertical pipelines 212a and 212b, which is the standard for opening or closing the centrally located air control valve 216a, was defined.

In addition to these control variables, in the output operation, the viscous friction coefficient generated for energy absorption in the generator may also be a variable that greatly affects the behavior of the variable water column vibration device 200 according to the present invention.

Therefore, in the output operation of the present invention air pressure in the air chamber (215a, 215b) to absorb the maximum energy from the period and amplitude of a given blue according to the aforementioned first and second control scheme (P _o) and the viscous friction coefficient, or set After obtaining the reference Z _s and the coefficient of viscous friction, the controller 225 can apply these control variables by scheduling them according to the amplitude and period of the wave.

Meanwhile, as a result of simulation of the present invention and the control method applied thereto, the present invention absorbs 1.5 to 2.6 times the energy when the first control method is applied as compared to the conventional energy absorbing wave generator in a wave condition such as the ocean, and the second The control method absorbs 1.9 to 2.2 times the energy.
