Definitions
- the present invention relates to a wave power generation apparatus that receives a wave force with multiple degrees of freedom through a wire.
- Wave is a high-density energy source among renewable energy sources, and it is an energy source that is attracting attention because it can be generated 24 hours a day, but research and development was started only in 1940. Wave generation is much slower in market formation than other renewable sources. Only recently (2008) are commercial systems available.

- the wave power generator of the present invention can reduce the initial installation and the construction cost compared to the pile, self-weighting, jacket-type offshore installation by mooring the floating body with a wire.
- the wave power generator of the present invention Since the wave power generator of the present invention generates power by mechanical energy transfer through a wire, it can efficiently absorb movement in various directions.
- the present invention receives a force or moment of six-axis degrees of freedom, including a three-axis translational movement of the float and a rotational movement about a three-axis, as a wire tension. Therefore, all changes in tension of the wire can be converted into energy, and an energy harvesting device with high efficiency can be realized. It can absorb all the energy of a floating body that is free to move.

- the wave power generation apparatus of the present invention may include a floating body 100, power generation unit 130, power transmission unit 120, wire.
- the power generation unit 130 receives electric power from the wire or the equalizer 150 to generate electric energy or hydraulic energy.
- the power generation unit 130 and the power transmission unit 120 constitute a power generation unit 140.
- Floating body 100 is a means to receive the wave force floating on the sea surface.
- the first axis, the second axis, and the third axis are defined as virtual Cartesian coordinate axes orthogonal to each other.
- the first axis may be viewed as the x axis, the second axis as the y axis, and the third axis as the z axis.
- the floating body 100 When the wave hits, the floating body 100 has a translational movement (Fx) about the first axis, a translational movement (Fy) about the second axis, a translational movement (Fz) about the third axis, and the rotational axis of the first axis.
- the rotary motion Mx, the rotary motion My which makes a 2nd axis a rotation center, and the rotary motion Mz which makes a 3rd axis a rotation center can be performed. Therefore, the floating body 100 performs a translational or rotational motion in which six degrees of freedom of motion components (Fx, Fy, Fz, Mx, My, Mz) are superimposed, and the kinetic energy in which six degrees of freedom of motion components are superpositiond. Occurs.
- a plurality of flexible wires may be connected to each floating body 100.
- the wires can be ropes, wires of synthetic fibers, chains and the like.
- the float wires WB1, WB2, and WB3 connected to the float 100 may include a first wire WB1, a second wire WB2, and a third wire WB3.
- the kinetic components Fx, Fy, Fz, Mx, My, and Mz of 6 degrees of freedom are driven through one or several wires of the first wire WB1, the second wire WB2, and the third wire WB3. It may be delivered to the delivery unit 120.
- At least three wires connected to each floating body 100 are provided, and three fixed points connecting three wires to the floating body 100 are formed in an imaginary triangle. It can be located at the vertex.
- the point where the first wire WB1 is fixed to the floating body 100 is the first fixing point 101, and the point at which the second wire WB2 is fixed to the floating body 100 is the second fixing point 102.
- the point where the third wire WB3 is fixed to the floating body 100 may be defined as a third fixing point 103. Wires may be spaced apart for multiple degrees of freedom energy absorption.
- Flexible wires can only receive tensile forces, not compressive or rotational moments. However, the separation distance between the wires is a factor that can receive a compressive force or a rotation moment force.
- the float 100 can be freely redirected. Thus, it cannot be a constrained structure that can receive six degrees of freedom motion. At this time, even if a plurality of wires are provided, it is difficult to absorb kinetic energy of multiple degrees of freedom.
- the triangular arrangement structure in which the wires are spaced at predetermined intervals of the present invention may restrict the rotation of the floating body 100. Therefore, the force restraining the rotation of the floating body 100 is transmitted to at least one of the tension of the plurality of wires, the tension of the individual wires are all absorbed by the energy in the power transmission unit 120, the efficiency can be increased. .
- the spaced arrangement structure of the wires also serves as a guide cable for preventing the floating body 100 from being separated during the operation of the floating body 100 or a mooring function for mooring the floating body 100 at a predetermined position. As such, it is important to dispose the plurality of wires so as to restrain each other. In the present invention, the wires are spaced apart to restrain the free redirection of the floating body 100 in order to increase the energy absorption efficiency.
- the width, width, and length of the floating body 100 are designed to be as similar as possible so that the degree of freedom of the floating body 100 in which energy is absorbed is not limited.
- the ratio of the horizontal, vertical and height of the floating body 100 such as spherical, hemispherical, disk, and cylindrical may be substantially similar, so that the direction of movement of the floating body 100 is not limited to a specific degree of freedom. It is preferable that the floating body 100 does not move only with a certain degree of freedom but moves evenly with respect to several degrees of freedom. To this end, it is preferable that at least one of the width, width and length of the floating body 100 does not have a difference enough to be an integral multiple of the other.
- the mechanical wave power generation apparatus by the wire of the present invention has high power transmission efficiency, and therefore may be installed only a small number of floats 100, which is advantageous for small-scale wave power generation.
- the wire transfer method is optimal for small on-shore wave power generation, and the device installation area can be minimized to be environmentally friendly. Can increase.
- wires are tensioned during the movement of the floating body 100, some of the wires may be released tension.
- One or more wires may be tensioned for six degrees of freedom translational or rotational motion in an unspecified direction. In the present invention, since all the wires are connected to the power transmission unit 120, all the kinetic energy of the floating body 100 can be absorbed into the power transmission unit 120 without omission.
- Wire is used to transfer wave energy absorbed from sea to land.
- the input wave force is proportional to the volume or number of the floats 100. In some cases, the weight of the floating body 100 reaches several to tens of tons.
- a small amount of deformation may reduce a loss of input energy consumed in the form of elastic deformation of the wire.
- the wire is repeatedly moved with respect to a specific reference point (for example, the direction switching unit 110), but the wave weight is not consumed by the inertia force when the mass of the wire is small. If the elastic modulus of the wire is large, the wave force input to the floating body 100 may be consumed by the elastic deformation of the wire. If the mass of the wire is large, the wave force input to the floating body 100 may be consumed in the acceleration / deceleration movement of the wire. As the elastic resistance and the inertial resistance of the wire become larger, the wave force transmitted to the power generation unit 130 may be reduced.
- a specific reference point for example, the direction switching unit 110
- the wire In order to increase the power generation efficiency, the wire should be a low deformation material or a lightweight material. In order to transmit power without loss, the wire is preferably free of tensile strain. The wire has a small modulus of elasticity such that power is not consumed by bending the wire in the turning part 110. In order to reduce the kinetic load of the wire, the wire is preferably a lightweight material. In order to reduce the frictional force consumed in the direction switching unit 110, the wire is preferably a small friction coefficient.
- the wire is preferably a light and low strain material, a non-metal wire is suitable.
- synthetic fibers By using synthetic fibers as the wire material, light weight and low strain conditions can be more easily satisfied.
- One end of the wire may be connected to the floating body 100, and the other end of the floating body 100 may be connected to the power transmission unit 120.
- the tension of the wire may be input to the power generation unit 130 via the power transmission unit 120.
- Each wire 100 may be connected to a plurality of wires in different directions.
- the diameter DW of the wire may be several centimeters (for example about 2 cm), and the cross-sectional area of the wire may be several to several tens of square centimeters (for example, 3.14 square centimeters).
- the tensile strength of the wire is 100 MPa (corresponding to about 1,000 kgf / cm 2)
- a wire of several centimeters in diameter for example, has a cross-sectional area of 3.14 square centimeters, and thus can support a tension of about 3 ton.
- the weight of the floating body 100 or the magnitude of the wave force acting on the floating body 100 may be several to several tens of tons.
- the amount of drainage pushed by the floating body 100 submerged in water may be at least 3 ton.
- the tensile strength of the wire should be at least 100 MPa.
- the tensile strength of the wire is less than 100 MPa, the following problem may occur.
- the diameter of the wire may be excessive, and if the diameter of the wire is excessive, there may be a problem in that external forces acting on the wire such as birds or waves may not be ignored.
- the mass of the wire may be excessive, and the excess mass of the wire may cause loss of wave force. This is because the wave force is consumed by the inertial momentum of the wire.
- the diameter of the wire is excessive, a problem may arise in that the direction changing member that supports the wire so as to be excessively large. The larger the turning member, the greater the consumption of wave force.
- the direction change member is smaller than the diameter of the wire, the bending deformation of the wire is increased, so that the curvature fatigue of the wire may be increased, and thus the service life may be reduced.
- the wire in order to increase the tensile strength in terms of the properties of the material, it is preferable to manufacture the wire from synthetic fibers rather than natural materials.
- the twisted structure of the wire can be improved to increase the load per unit area.
- the synthetic fibers that make up the wire are at least one of polyester fibers, polyethylene fibers, polypropylene fibers, nylon fibers.
- Polyester fibers are polymers having an ester bond (-CO-O-) in the main chain of the molecule.
- the polyester may be a thermoplastic saturated polyester or a thermosetting unsaturated polyester. It can be prepared by mixing terephthalic acid and ethylene glycol, heating and polymerizing.
- the elastic recovery property is very excellent because it recovers 97% at 2% elongation, and particularly, the property of recovering immediately after small elongation is suitable to secure the low elongation of the present invention.
- Polyethylene fiber is a chain-like high molecular compound polymerized with ethylene. It may include both low density polyethylene and high density polyethylene. Since polyethylene fiber has a density of about 0.9, it can meet the criteria of the present invention in terms of specific gravity and tensile strength.
- the polypropylene fiber has a melting point of 165 ° C. and can be used continuously at 110 ° C. under high load, and thus may be suitable as the wire of the present invention in terms of heat resistance and durability.
- the advantages such as density and chemical resistance of about 0.9 can meet the specific gravity and tensile strength requirements of the present invention, like polyethylene.
- the wire may have a shape in which several detailed strands 172 are twisted.
- Each of the detailed strands 172 may be formed by agglomerating the polymer filament 170 with a molecular weight of 20,000 or more.
- the length deformation of the wire should be small during the tension action. This is because energy is consumed by the longitudinal deformation of the wire. Accordingly, the wire is preferably low in elongation even when a large tension is applied, and the wire may have a low elongation below the elongation limit.
- the elongation at break when the wire breaks with increasing tension is preferably 15% or less.
- the elongation limit value may be 15%, which is the maximum value of the elongation at break.
- the elongation at break of the entire wire is not limited to the elongation at break of the polyester fibers themselves. It can be minimized.
- the wave energy is consumed in various forms before being transmitted to the power generation unit 130.
- energy consumed without being delivered to the power generation unit 130 is as follows.
- Wave energy is consumed by the inertia of all moving parts.
- the input energy may be consumed by the inertia force (or inertia resistance) of the floating body 100, which is a value obtained by multiplying the acceleration by the mass of the floating body 100.
- the input energy can be consumed by the inertial force (or inertia resistance) of the wire, which is the product of the mass of the wire times the acceleration.
- the input energy may be consumed by the inertia force (or inertia resistance) of the power transmission unit 120, which is a value obtained by multiplying each acceleration by the mass moment of inertia of the rotating shaft and the gear installed inside the power transmission unit 120.
- the specific gravity of the wire is preferably greater than 0.5 and less than 2 within the range satisfying the tensile strength condition and the elongation condition.
