Description

Coastal fixed wave generator

The present invention relates to a coastal stationary wave power generator, and more particularly, to a coast stationary wave power generator, in which a pendulum motion force is acquired by a horizontal motion wave fixed on the sea floor near the shore and proceeding bidirectionally on the water surface, The pendulum motion force is transmitted to the ground traction power transmission device and the generator side so that a continuous large output can be obtained without interruption even if the wave of the wave is not transmitted, And the buoyant pulley forces the reverse pendulum motion of the pendulum motion part to be forced, so that the repetitive pendulum motion corresponding to the horizontal motion of the wave is obtained To be performed smoothly, and to be quickly And even if waves of waves are transmitted in various directions, the structure is improved so as to satisfy sufficient durability while acquiring wave energy from a multi-directional current through a joint having a clearance, and the multi-direction And an automatic tension unit that prevents wire sagging by a steel wire power transmission method in the energy transfer process of converting the wave energy acquired from the sea into pendulum movement force by a wire power transmission type is constituted, The present invention relates to a coast stationary wave power generator having an improved structure.

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. However, the wave motion appears as a mixture of up and down motion and 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.

Types of wave power generation include a vibration frequency mold, a wall wave type, and a movable object type, and classified into a fixed type and a floating type depending on the installation type.

In the case of the moving object type that directly uses the wave motion in the wave power device, the primary energy conversion appears as the motion mode of the subject, and when the motion of the subject according to the wave is classified into five modes, In this device, we analyze the motion characteristics of this body, and developed the horizontal motion wave power generator by using the fact that the up and down motion and the horizontal motion are always present in the case of float. .

In the wave power generation, the fixed type float is to fix the pile by the method such as the hunting, and the floating type obtains the energy while the floating body absorbs the fluctuation of the wave while drifting on the sea surface of the sea.

The movement of the coastal wave is a continuous wave of waves with a mixture of regular and irregular waves in the open terrain and other closed terrain. That is, continuous cyclic movements with irregular periods and irregularities appear.

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.

In addition, in the existing buoyant wave power generation system, there is a fear that the force of returning the floating body to the fixed position by the movement force of the wave pushing force and pushing force during the pendulum movement by the floating body is weakened, There is a possibility that the pendulum rotation of the fluid may not be properly performed.

In addition, the existing buoyant wave power generation system is required to have a float supporting structure suitable for the multi-directional movement of the waves, because the waves of the waves of the coastal waves are mixed with the regular waves and the irregular waves continuously.

In addition, the conventional wave power generation system has a complicated structure for supporting the pendulum motions and the pendulum motions, so that it is not easy to install and maintenance is difficult due to frequent breakdowns, which results in poor efficiency of power generation.

In addition, when it is installed in a remote place rather than a coast, it is vulnerable to a natural environment such as a storm.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and its object is to provide a pendulum system that repeatedly performs pendulum movement by a floating body installed on a waterfront along the motion of a wave, As shown in FIG.

Another object of the present invention is to provide a pneumatic power transmission system in which the pendulum motive power is acquired by a wire power transmission system in which a wire automatic tension unit is installed to prevent the sagging phenomenon of the wire and transmit the power to the terrestrial coercive force transmission device without energy loss.

In this case, since the transmitted pendulum motive force is transmitted as a wave in which the motion of the wave is transmitted, the generator is rotated by the rotation output of the gear box which continuously rotates in one direction regardless of whether or not the wave energy is transmitted.

In order to stably obtain the primary wave energy, a vertical support is fixed to the sea floor, a rotary shaft is arranged laterally on a vertical support, and a floating body is suspended on the rotary shaft. Pendulum movement will be done.

In order to solve the problem that the pendulum motion is not repeatedly generated due to the weak intensity of the waves, the pendulum motion can be rotated by the rotation axis and the pivot axis Buoyancy is accumulated in the buoyant pulley which is composed of the buoyant force, and buoyancy is accumulated in addition to the depth of the water depth.

Here, if the installation angle according to the rotation angle of the float and the buoyant body is adjusted, the float body is not received in the initial rotation, and the floating body is started to flow when the floating body moves beyond the predetermined arc angle, The greater the size of the fluid, the greater the buoyancy can be generated, so that a stable pendulum motion can be realized.

If we look at the motion of the float, the wave motion is combined with the vertical movement and the horizontal movement, so that a device for adding the up and down movement of the wave to the horizontal movement force is devised.

The rotation of the water particles is caused by the rotational motion of the body, but when the floating body moves upward, the forward pendulum motion is performed. In order to allow the floating body to move downward while performing the reverse pendulum movement, In this system, the floating body can be moved up and down with respect to the lifting support.

Since the direction of ocean currents in the ocean is not constant, the direction of waves traveling to the float is not forward direction. Therefore, the float is a structural shaft type that can cope with torsion with respect to a wave traveling in multiple directions, and it can constitute a connecting joint composed of female and male spline lines so as to maintain pendulum torque.

The absorbed wave energy appears as a pendulum motion, and in transferring the pendulum motive force by the wire transfer method, the wire sagging phenomenon, that is, the idling phenomenon, can not be transmitted because the power is not transmitted, and the wire becomes strained. Thus, an automatic tensioning device is constructed to maintain the limit wire strain.

Land-based power harvester is a safe land-based installation to prevent loss by typhoon. The pendulum force transmitted from the wire carries wave energy in the form of a cycle of waves.

Therefore, when the wave is hit, the wire is pulled so that the power gear rotates in the forward direction and the first and second weights are further increased. When the wave is not applied, the first and second weights are further lowered and the power transmission gear is rotated in reverse. And the reverse rotation force is output through the gear box at a constant unidirectional rotational force so that the generator can obtain a continuous output.

The present invention is characterized in that the floating body installed on the waterfront along the coast by the motion of the wave forces the pendulum movement repeatedly to acquire the wave energy and to continuously appear as the pendulum movement force.

The obtained pendulum motive force is a wire power transmission system in which an automatic tensioning device is constituted, and the power is transmitted to the land traction power transmitting device without energy loss.

Since the transmitted pendulum motive force is transmitted in the wave form in which the motion of the wave is transmitted, the pendulum motive force is converted into the continuous rotational force by using the plurality of weight weights and transmitted to the generator side, So that continuous driving force is transmitted without interruption even if the wave of the wave is not transmitted.

1 to 14, a coastal fixed wave power generator according to the present invention includes: a left and right vertical support 110 coupled to an end of a coast; A floating block 130 bound to the upper portions of the left and right vertical supports 110 and capable of ascending and descending with respect to the movement of waves; A fixing block 120 disposed below the floating block 130 and fixed to the left and right vertical supports 110; At least one connection joint 240 rotatable on the left and right sides of the connection block 215 is horizontally supported on the floating block 130 and is provided with a connection block 215, A pendulum motion part 200 connected to an upper side of the connection block 215 and connected to the pulley pulley 225 side to transmit rotational force of the float 300; A float 300 connected to the lower side of the connecting block 215 to pendulum by a horizontal movement force of waves; A buoyancy pulley (260) rotatably coupled to the rotating shaft (210) to assist pendulum movement of the pendulum movement part (200); A pulley support 270 connected to both ends of the flywheel 261 of the buoyancy pulley 260 and having an upper portion and a lower portion capable of rising and lowering in accordance with the movement of waves and having a lower portion fixed to the sea floor; A kinetic energy conversion unit connected to the vertical connection unit 220 for switching the pendulum motion of the pendulum movement unit 200 to rotational force; A gear box 500 disposed on the ground and adapted to convert the rotational force of the moment converting portion transmitted through the wire member 410 into a continuous rotational force in a weight weight and one-way clutch transmitting manner; And driving force transmitting means for transmitting the output of the gear box 500 to the generator 620 side.

Referring to FIG. 1, the left and right vertical supports 110 are formed in the shape of a sharp-pointed lower end, and the lower ends thereof are embedded in the seabed surface of the shore in an engaging or drilling method.

The left and right vertical supports 110 may employ steel pipe pile files.

The float 300 in the sea is subjected to a six-soul due to waves. The fluctuation of the float 300 depends on the movement of the float 300 in the longitudinal direction of the float 300, Swaying, vertical and vertical movements, and rolling, rolling, yawing, yawing, and yawing, which are the rotational movements of the fore and aft, left and right, ), It becomes difficult to absorb wave energy by 6 degrees of freedom motion.

Accordingly, the present invention is installed on the seafloor surface of the coast with the left and right vertical supports 110, which are fixed type steel pipe pile files, and the pendulum motion part 200 is loaded, so that stable wave energy can be obtained.

The floating block 130 supporting the rotary shaft 210 and the upper portions of the buoyant pulley 260 and the pulley support 270 are allowed to float in response to the wave motion of the up and down motion, As shown in Fig.

The rotational force transmitted from the pendulum movement unit 200 is transmitted to the gear box 500 through the automatic wire tension unit 450 disposed on the ground.

The buoyancy pulley 260 is attached to one side of the pulley body 262 to impart a restoring force when the pendulum motion of the pendulum motion unit 200 is performed And a plurality of buoyant members 264 that are formed on the surface.

The plurality of buoyant bodies 264 are disposed on the left side of the drawing with respect to the axle 261 of the buoyant pulley 260.

The buoyant body 264 is formed to have a larger volume as it goes from the lower side to the upper side (toward the rotation direction of the hour hand) so that the buoyancy above the lower buoyancy is larger.

That is, the buoyant body 264 has a larger volume as it goes from the lower first buoyant body 264a to the second, third, and fourth

buoyant bodies

264b, 264c, and 264d on the upper side.

Thus, when the buoyant body 264 is submerged in accordance with the rotation of the buoyancy pulley 260, buoyancy forces of different magnitudes are generated for the first, second, third and fourth

buoyant bodies

264a, 264b, 264c and 264d , So that the reverse rotation torque is always operated.

The buoyant body 264 becomes bulky as it goes from the lower side to the upper side, and buoyant force is gradually increased in the counterclockwise direction when the buoyant body 264 is submerged in the counterclockwise direction.

Referring to FIG. 2, the left and right vertical supports 110 are arranged at left and right sides of the float 300, and the fixing block 120 is fixed to the left and right vertical supports 110 .

The connecting block 215 is a box-shaped structure provided in the middle of the rotating shaft 210 and suspended from the float 300. The connecting block 215 is rotatably connected to the pulley pulley 225 via the vertical connecting rod 220 .

In the wave motion, the up and down motion and the horizontal motion are always present, and the up and down motion is the rotation motion of the water particle, which causes the float to appear as a circular orbital motion, and the horizontal motion appears as a sine wave with irregular wave and period .

The float 300 suspended in the connection block 215 undergoes pendulum movement, but the rotational motion of the water particles appears as a pendulum motion in which the float 300 moves up and down.

Therefore, in order to absorb the up-and-down movement force, the float 300 needs to be structured to move up and down, or the up-and-down support 251 must absorb the up-and-down movement force.

The cushioning spring 257 wound on the lifting supporter 251 passing through the binding bracket 340 of the float 300 moves the up and down movement force of the wave . &Lt; / RTI >

When the wave is stopped or weakened, the buoyant force acts on the buoyant pulley 260 operating in conjunction with the rotary shaft 210, .

In other words, the operation of the buoyant body 264 is such that the progressive force of the wave acts on the buoyant body 264 to a larger force than the buoyant body 264, so that the upper part of the pendulum movement part 200 is directed to the sea side The wire member 410 wound around the pulley pulley 225 is pulled in the direction opposite to the traveling direction of the wave as the lower portion of the pendulum movement unit 200 is positively rotated to be inclined to the position P1, The first and second weight scales 545A and 545B rise and the tension weight 456 shown in Fig. 8A rises.

[

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 motion force of the first driven shaft 505 → the second driven shaft 510 → the first drive shaft 520 → the first power transmission portion 570 → the forward one way clutch 550 → the second drive shaft 530, The power is transmitted from the chain gear 590 to the speed changer 610 to the generator 620 and the driving force of the first interlocking shaft 505 is transmitted to the second and third connecting

sheaves

504a and 504b on the left and right sides So that the first and second weight scales 545A and 545B rise and become stored in the position energy.

At this time, the rotational driving force of the second interlocking shaft 510 is selectively transmitted to the interlocking member 509 side in accordance with the rotation direction of the second interlocking shaft 510, and the forward one-way clutch 550 transmits the fourth power transmission Since the second driving shaft 530 is rotated in one direction in the process of being transmitted from the first driving shaft 520 to the second driving shaft 530 through the first power transmitting portion 570, And the second driving shaft 530 blocks the reverse driving force which is rotated in the other direction.

The first and

second weights

545A and 545B are lowered when the wave of the wave is not transmitted to provide a reverse rotation force to the first interlocking shaft 505. [

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.

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.

14, the reverse operation of the gear box 500 (when the wave of the wave is not transmitted) is transmitted through the first and

second weights

545A and 545B, the second and third connecting

sheaves

504a and 504b ) First interlocking shaft 505 second interlocking shaft 510 first driving shaft 520 second power transmitting portion 575 second driving shaft 530 first and second reverse one

way clutches

At this time, the forward one-way clutch 550 is built in the fourth power transmission gear 570d to block the driving force transmitted through the first power transmission portion 570. [

Therefore, even if the wave period of the wave becomes longer and the rotational force is not transmitted to the first connecting sheave 503, the energy of the first and second weights 545A, It is possible to generate continuous power without disconnection to the side of the power source 610 side.

That is, in the gear box of the present invention, the rotational force of the first interlocking shaft 503 is raised by the first and second weight scales 545A and 545B during the forward operation to store the energy as position energy, The first and

second weights

545A and 545B are rotated down while the potential energy of the first and

second weights

545A and 545B is output through the chain gear 590. [

The forward motion of the gear box 500 (when the waves are transmitted) is such that when the second connecting wire 414 in the form of a wire is pulled, a rotational force to rotate the first interlocking shaft 505 is transmitted to the first connecting sheave 503 The rotating force of the first interlocking shaft 505 is transmitted to the first and second power gears 502 and 506 and the second interlocking shaft 510 and the rotating force of the second interlocking shaft 510 is transmitted to the interlocking member 509 The first driving shaft 520 is rotated in one direction.

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 and transmit the power to the outer booster 610 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 weights

545A and 545B are rotated downward, the reverse rotation of the gear box 500 (when the wave of the wave is not transmitted) Is transmitted to the second interlocking shaft 510 through the first interlocking shaft 505 via the first and second power gears 502 and 506 and the rotational force of the second interlocking shaft 510 is transmitted through the interlocking member 509 The first driving shaft 520 is rotated in one direction. The second driven shaft 510 is transmitted to the first drive shaft 520 to drive the first drive shaft 520 in the reverse direction and transmits the rotational force to the second drive shaft 530 through the second power transmission portion 575, The chain gear 590 provided on the second drive shaft 530 rotates together and transmits the power to the outer booster 610 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 570 is prevented from being transmitted to the second driving shaft 530 side.

Therefore, even if the wave period of the waves becomes longer and the rotational force is not transmitted to the first and second interlocking

shafts

505 and 510 through the second connection wire 414, the rotation speed of the first and second weight scales 545A and 545B The driving force can be transmitted to the external booster 610 by using the kinetic energy generated in the operation, 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 is used for maintenance or evacuation of the equipment, 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.

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 disconnection by using the kinetic energy generated in the lifting operation of the 1,2 weight scales 545A and 545B and the one-way clutch transmission scheme of the gear box 500. [

In addition, since the vertical support 110, which is a plurality of steel pipe pile files, is installed on the seafloor of a coastal area in a coastal area, the energy absorption rate of the waves is great.

Since the buoyant pulley 260 is rotated in conjunction with the rotary shaft 210 and a plurality of buoyant bodies 264 are disposed on the buoyant pulley 260, (200) is returned in the reverse rotation direction, so that the pendulum motion can be smoothly performed.

Further, since the size of the buoyant body 264 is increased toward the opposite direction of the hands, it is possible to further increase the pendulum movement force during the reverse rotation of the pendulum movement unit 200.

Since the rotary joint 210 is divided and the connecting joint 240 is rotatably disposed at both ends of the divided shaft and is rotatable, it is possible to flexibly absorb the wave force even if twisting occurs in the multi- Respectively.

Since the connecting means 250 of the present invention is rotatably coupled with the coupling bolts 255 in the first and second connection holes 252a and 254a with clearance, So that the multi-directional pressure of the waves can be relieved.

In addition, since the floating block 130 and the upper pulley support 272 supporting the rotary shaft 210 are lifted and lowered by the floating force, the present invention has an advantage that it can respond quickly to changes in the water level in the sea.

In addition, the buoyancy pulley 260 and pendulum motion part 200 of the present invention can stop the rotation at the time of an emergency in which a storm occurs, thereby reducing the risk of component breakage.
