Description

Wave power generation apparatus

In particular, the present invention relates to a wave power generator, and more particularly, to a wave power generator that transmits a continuous driving force to a generator by regenerative power using a pendulum motion and a pendulum motion force, The structure can be improved so that sufficient durability can be satisfied even if the waves of waves are transmitted in various directions and the waves can be structurally absorbed in the multiple directions in which the waves are transmitted To a wave power generator in which the structure of the wave power generator is improved so as to disperse the wave load burden of the float using the floating type mooring means and to suppress the flow and to move it when necessary.

Generally, wave power generation is a phenomenon in which water particles move back and forth when the water surface periodically moves up and down by a wave, and this motion is converted into electric energy through an energy conversion device.

Wave power generation is divided into two methods, one is vertical wave motion and the other is horizontal motion.

These wave power generators can be divided into two types depending on the installation method: the floating type and the fixed type. First, the floating type is excellent in the efficient utilization of the wave energy by the floating device in the sea and in the vicinity of the facility.

Next, the stationary type is installed on a fixed substrate, which is advantageous in design and construction, and can be used with other facilities such as breakwaters and is easy to receive the extracted energy.

In addition, it can be divided into wave up and down motion, horizontal motion and wave power using underwater pressure according to the method of using wave energy.

Of these, the principle of operation of the inertial type and the air turbine system is as follows. The large part of the structure of the apparatus is a vertical cylinder, the diameter is several tens cm, and the length is several meters. The bottom is opened and water can flow freely.

The buoy is attached to the upper part of the cylinder to prevent the entire cylinder from sinking, and the motion of the wave is small as it goes away from the water surface, so the water surface in the cylinder does not move much.

On the other hand, buoys move upward and downward by waves, so that the water surface in the cylinder moves up and down relative to the cylinder. Therefore, the pressure in the air chamber fluctuates.

There is also an air inlet at the top of the cylinder, which consists of a retrofit device that is only open to the inside. As the water level in the cylinder decreases, the air flows into the air chamber as the air chamber pressure decreases. When the water level rises, the pressure rises and flows out through the air turbine installed above. At this time, as the air turbine rotates, the generator connected thereto generates electric power.

Prior art relating to existing wave power generation is disclosed in Korean Patent Registration No. 10-0989594 entitled " Wave Power Generation System Using Floating Structure "(registered on October 18, 2010) A first connection part having one side connected to one side of the lower end of the floating structure and the other side made of a thread, and a second connection part having one side connected to the threaded part of the first connection part, And an electric power generator for generating electric energy in accordance with the rotation of the rotary device, wherein one side is connected to the other side of the rotary device and the other side is connected to the fixing part And a second connection part fixed to the sea bed surface through the second connection part.

In this case, since the second connection portion is fixed to the sea floor rather than the sea surface, and the first connection portion is connected to the lower end of the floating structure and is vertically moved up and down according to the difference of the wave height, it is troublesome to fix the second connection portion to the sea floor And the axial force due to the spiral rotation of the first connection portion during the up and down movement of the floating structure is transmitted to the rotating device to drive the power generating device incorporated in the rotating device. However, in the case of the wave, The wave energy of the wave is large, but merely converting the rotational force of the floating structure to the axial force of the spiral first connection part is not satisfactory in efficiency, and there is a fear of damage to parts due to contact.

Other prior art related to conventional power generation is disclosed in Korean Patent Registration No. 10-1155290 entitled " Wave Power Generation System "(Registered on June 06, 2012), which includes a casing, both ends of which are fixed to both sides of the casing A hollow rotor mounted on a bearing provided on both sides of the stationary shaft and the stationary shaft and having a function of changing the reciprocating flow energy of the fluid directly into rotational energy by attaching a blade to the outer circumferential surface, And a fixed stator.

However, the conventional wave power generation system has disadvantages in that the wave of the wave is cut off as the wave period is long and unstable.

That is, the conventional wave power generation system has a disadvantage in that the energy density is low but the efficiency compared with the wind power generation photovoltaic generation which is continuously used is low because the conventional wave power generation system uses the power of the sen wave intermittently because the wave period is slow and the wave power is irregular .

In addition, such a conventional wave power generation system is complicated in its structure and thus is not easy to install, and thus there is a problem in that efficiency of power generation is not large.

In order to improve this, a conventional wave power generation system is required to have a wave power generator capable of continuously obtaining output, not a power failure.

9 and 10, when the wave is transmitted in the wave, the pendulum motive force of the motion-switching unit 400 is transmitted to the first connecting sheave 503 through the wire-shaped connecting member 460 and the first connecting sheave 503 Is transmitted to the first interlocking shaft 505 and the rotational force of the first interlocking shaft 505 is transmitted to the first forward one-way clutch 505 through the first and second power gears 502, 506 and the second interlocking shaft 510, And the rotational force of the second driven shaft 510 rotates the first drive shaft 520 through the interlocking member 509. [

 The gear box 500 of the present invention performs a positive action when the wave power of the wave is transmitted to the pendulum motive force, The pendulum motive force of the first driven shaft 505 → the second driven shaft 510 → the first forward one-way clutch 550a → the first drive shaft 520 → the first power transmitting portion 570 → the second forward direction circle The drive force of the first drive shaft 520 is transmitted to the left and right sides of the first drive shaft 520 while the power is transmitted to the second drive shaft 550 through the second drive shaft 530, the chain gear 590, the gearbox 810, and the generator 850, 545B are transmitted to the second power transmission portion 575 → the first and second transmission portions 515A and 515B → the first and second weight portions 545A and 545B to rotate the first and second weight portions 545A and 545B forward The power transmission path is provided.

At this time, the first forward one-way clutch 550a selectively transmits the rotational driving force of the second interlocking shaft 510 to the side of the interlocking member 509 in accordance with the rotating direction of the second interlocking shaft 510, Since the forward one-way clutch 550b is embedded in the fourth power transmission gear 570d, the forward one-way clutch 550b is transmitted from the first drive shaft 520 to the second drive shaft 530 through the first power transmission portion 570, 2 driving shaft 530 transmits the forward driving force in one direction and blocks the reverse driving force in which the second driving shaft 530 is rotated in the other direction.

The first and second weight portions 545A and 545B receive the rotational force from the output shaft 515-1 of the first and second speed change portions 515A and 515B and are rotated by the stopper means 50 And when the wave of the wave is not transmitted, it is rotated in a downward direction to provide a reverse rotational force to the first drive shaft 520 through the first and second speed change portions 515A and 515B.

The first and second weights 545A and 545B interfere with the fixed block 54 while the rotating piece 52 is rotated and the first and second weight portions 545A and 545B interfere with each other during the interference of the rotating piece 52 and the fixed block 54 The restoring spring 55 is contracted as the restoring spring 55 is brought into contact with the restoring spring 55 and the resilient restoring force of the restoring spring 55 contracted when the wave of the wave is not transmitted, , The output shaft 515-1 of the two speed change sections 515A and 515B is rotated in the opposite direction to impart the reverse rotational force to the first and second speed change sections 515A and 515B.

When the second drive shaft 530 is operated in one direction, the gear box 500 includes the first drive shaft 520, the first and third rotary gears 575a and 575c of the second power transmission portion 575, The first and third power transmission gears 570a and 570c of the power transmission portion 570 are rotated in the forward direction while the second drive shaft 530, the second rotary gear 575b, the second and fourth power transmission gears 570b , 570d are rotated in the opposite direction.

At this time, the first and second reverse one-way clutches 560a and 560b shut off the power transmitted through the second power transmission portion 575, 2 driving shaft 530 and the driving force transmitted from the second power transmitting portion 575 can be prevented from colliding with each other.

13, the reverse operation of the gear box 500 (when the wave of the waves is not transmitted) is transmitted to the first and second weight portions 545A and 545B, the first and second transmission portions 515A and 515B The first drive shaft 520, the second power transmission portion 575, the second drive shaft 530, the first and second reverse one-way clutches 560a and 560b, the chain gear 590, To the generator 850. [0060]

At this time, the first forward one-way clutch 550a blocks transmission of the rotational force of the first drive shaft 520 in the reverse direction through the interlocking member 509, and the second forward one- So that the driving force transmitted through the first power transmitting portion 570 is blocked by the transmission gear 570d.

Therefore, even if the wave period of the wave becomes long and the rotational force is not transmitted to the first connecting sheave 503, the energy of the external energy generated by the first and second weight portions 545A and 545B It is possible to generate continuous power without disconnection to the side of the power source 810.

That is, in the gear box of the present invention, the first and second driving shafts 520, 515A and 515B have first and second gears 515A and 515B, respectively, The first and second weight portions 545A and 545B are rotated while the one heavy portion of the first and second weight portions 545A and 545B is rotated downward while the first and second weight portions 545A and 545B are rotated. And 545B are output through the chain gear 590. The chain gears 590 and 530 are connected to the chain gears 590 and 560, respectively.

When the wire-shaped connecting member 460 is pulled, the forward movement of the gear box 500 (when the waves are transmitted) is transmitted to the first connecting sheave 503 with a rotating force for rotating the first interlocking shaft 505 The rotational force of the first interlocking shaft 505 is transmitted to the second interlocking shaft 510 through the first and second power gears 502 and 506 and the first forward one-way clutch 550a, The first driving shaft 520 rotates in one direction through the interlocking member 509.

The first driving shaft 520 is rotated in one direction to transmit the rotational driving force in the forward direction to the first and second speed changing portions 515A and 515B so that the first and second weight portions 545A and 545B are rotated by the stopper means 50, Through the first, second, third, and fourth power transmission gears 570a, 570b, 570c, and 570d of the first power transmission portion 570, The second drive shaft 530 is rotated.

Meanwhile, since the forward one-way clutch 550 provided in the fourth power transmission gear 570d is driven in one direction to drive the second drive shaft 530, the chain gear 530 provided in the second drive shaft 530 590 rotate together to transmit the power to the outer booster 810 side through the chain member 595.

At this time, the first drive shaft 520, the first and third rotary gears 575a and 575c of the second power transmission portion 575, the first and second sheave pulleys 62A and 62B, the first power transmission portion 570, The second drive shaft 530, the second rotary gear 575b and the second and fourth power transmission gears 570b and 570d are rotated in the reverse direction .

The reverse one-way clutch 560 interrupts the power transmitted through the second power transmission portion 575 and rotates in a direction opposite to the rotation direction of the second drive shaft 530 driven through the first power transmission portion 570 It is possible to prevent the driving force from being transmitted and colliding with each other.

As the first and second weight portions 545A and 545B whose eccentric center of gravity is decentered are reversed (when the wave of the wave is not transmitted) of the gear box 500, the first and second weight portions 545A, 545B are transmitted to the first drive shaft 520 via the first and second speed change portions 515A, 515B to drive the first drive shaft 520 in the reverse direction, and the second drive transmission portion 575 The chain gear 590 provided on the second drive shaft 530 rotates in conjunction with the rotation of the second drive shaft 530 so that the power is transmitted to the outer booster 810 through the chain member 595.

The forward one-way clutch 550 transmits the reverse drive force to the first drive shaft 520 so that the fourth drive power transmission gear 570d and the second drive shaft 530 are slip- So that the rotational force transmitted through the first power transmitting portion 575 is prevented from being transmitted to the second driving shaft 530 side.

Accordingly, even if the wave period of the waves becomes long and the rotational force is not transmitted to the first and second interlocking shafts 505 and 510 through the connecting member 460, the first and second weight portions 545A and 545B The driving force can be transmitted to the external booster 810 side by using the generated kinetic energy, so that there is an advantage that continuous power can be generated without interruption.

The gear box 500 of the present invention further includes a stop means 60 for stopping the first drive shaft 520. The stop means 60 includes first and second weight portions 545A And 545B of the first and second driven pulleys 62A and 62B and is interposed between the holes of the first and second driven pulleys 62A and 62B and is coupled to the first drive shaft 520. The first and second driven pulleys 62A and 62B, A stopper bar 65 for stopping the rotation of the stopper bar 65B and a support hole 64 for a stationary frame 501 for supporting the stopper bar 65 to slide laterally.

Referring to FIG. 14, the present invention may further include a bow end for protecting the pendulum body 300 by fitting the pendulum body 300 so as to be spaced from the water surface in the event of an emergency such as a storm or a typhoon.

The hinge pin 930 is coupled to the upper end of the connecting rod 350 so that the lower portion of the connecting rod 350 can be foldably connected to the upper portion of the connecting rod 350 by a hinge operation, and a long wire 945 connected to the lower portion of the connecting rod 350 is wound around the connecting rod 350 A pin cover 950 which is coupled to surround a portion of the connecting rod 350 to which the hinge pin 930 is coupled and a lifting winch 940 for pulling the lower portion of the pendulum body 350 and the pendulum body 300, And a lifting winch 960 for lifting up the pin cover 950 in a rotating operation by winding up a lifting wire 965 connected to the lifting wire 950.

The lifting winch 940 is constituted of a drum type in which the main wire 945 is wound around the outer periphery while being rotated. Here, a handle-type manual lifting winch is shown here, but an electric lifting winch using a motor can also be used.

The long bow end can prevent the lower portion of the connecting rod 350 from being folded because the pin cover 950 is positioned outside the connecting rod 350 to which the hinge pin 930 is normally coupled.

On the other hand, in an emergency, when the lifting wire 965 is wound by rotating the lifting winch 960, the pin cover 950 is lifted and the hinge pin 930 is exposed to the outside, The lower part of the connecting rod 350 is lifted by lifting the wire 945 to lift the pendulum body 300 toward the upper fluid 710 and then the mooring wire 630 connected to the strap buckle member 640 is lifted up , The wave generating device of the present invention can be evacuated to the barge line side after the mooring function is released.

Fig. 15 is a view showing another embodiment of the mooring means of the present invention. In the mooring means of another embodiment, a buoy 660 is further added to the structure of the mooring means described above. The buoy 660 includes a strap buckle member 640, And connected to float on the surface of the water.

Since the buoy 660 and the mooring weight 650 are connected to the float 700 through the mooring wire 620 and the tensile force is applied thereto, it is possible to restore and cancel the motion due to the water level fluctuation, ) Is balanced, and it has an advantage that the shock can be dispersed against the wave load of the wave to reduce the flow.

16, the moving buckle member 640A is moved to the left and right according to the variable movement of the wave load transmitted to the left and right sides of the float 700 A mooring wire connecting the mooring weight 650 with the buoy 660 provided outside the right side inflow fluid 700 when a force to be pulled by the wave load acts on the right inflow fluid 700, 620 to act on the moving buckle member 640A to the right.

That is, by connecting the mooring wire 620 to the buoy 660 through the mooring wire 620 to the outside of the mooring sheath 630 provided on the left and right sides of the float 700, The tension of the mooring wire 620 is interlocked with the tension wire 640A.

As a result, when one of the float 700 receives a large wave load and the other wave transmits relatively low waves, the moving buckle member 640A positioned in the middle when a large amount of tension is applied to the "A" The wave load can be canceled by using the moving resistance of the mooring wire 620 and the water flow resistance of the buoy 660 when moving to the left side of the drawing.

When the wave load transferred to the float 700 disappears, the moving buckle member 640A is returned to its original position by its own weight of the moored weight weight 650 provided at the "B" site.

The moving buckle member 640A of the present invention is positioned on the upper surface of the float 700 and the left and right sides of the float 700 are connected to the left and right moored weight weights 650 And the buoy 660 are connected to each other, the mooring wire 620 and the moving buckle member 640A are moved to the left or right side according to the variation of the wave load, so that the wave load is dispersed and the wave load is canceled The mooring wire 620 and the moving buckle member 640A are returned to their home positions.

That is, before the wave load is generated, the moving buckle member 640A is disposed at the center position of the float 700 as shown in (A) of Fig. 16, The mooring wire 620 and the moving buckle member 640A are moved toward the left side A in the figure as the buoy 660 and the mooring weight 650 are pulled when the wave load A is generated, The mooring wire 620 and the moving buckle member 640A which are pulled to the left side (A) side as shown in (C) of Fig. 16 are moved in the direction of (B) The movable buckle member 640A is positioned at the center of the guide rail 640B by the weight of the buoy 660 and the mooring weight 650 on the side of the moving buckle member 640A.

The buoyant force and the flow due to the water level fluctuation transmitted to the mooring wire 620 are absorbed by the fluctuation of the wire tension generated due to mutual tension of the moored weight weight 650 when the water level fluctuates due to tide and ebb.

In the case of the conventional wave power generator having the period in which the pendulum is moved according to the floor and the valley of the wave, the wave power generation is disconnected in the wave corrugated part of the present invention, It is possible to generate continuous output without interruption by using the kinetic energy generated in the rotation operation of the 1,2-weight portions 545A and 545B.

The present invention is also connected to upper and lower shafts 362 and 364 through a locking projection 361 and a fitting groove portion 363 to provide clearance to an intermediate connecting member 360 connected to the pendulum body 300, And the universal joint 415 are disposed on both sides of the connection plate 410 so that the wave can be absorbed smoothly even if twisting occurs in the multi-directional current.

17 and 18, it is possible to adopt a structure in which the pendulum body 300 and the motion-force switching unit 400 are not plural but one, It will be obvious that any modification can be made without departing from the spirit of the invention.
