Description

Tidal-responsive wave power generation device

[0001] The present invention relates to a wave power generation device capable of efficiently utilizing the kinetic energy of waves by flexibly responding to changes in sea level due to tidal differences.

[0002] Wave power generation is a method of generating power by using the kinetic energy of waves. It is a power generation method that generates mechanical energy by connecting a device that can generate power from the movement of waves and converting the mechanical energy into electrical energy.

[0003] And currently commercialized wave power generation systems are classified into mobile body type, oscillating water column type, and overtopping type according to their operating principles. Here, the mobile body type converts the movement of an object that reacts sensitively to the movement of the water surface into electrical energy, but has the disadvantage of not being able to utilize transverse wave energy. The oscillating water column type generates electricity by converting wave power into air flow, but has the problem of low power generation efficiency due to secondary conversion. In addition, the overtopping type wave power generation converts wave energy into potential energy by placing a slope in front of the direction of wave propagation, but has the problem of low energy generation compared to the installation cost.

[0004] Looking at the previously disclosed movable body type wave power generation technology, Korean Patent No. 10-1638734 discloses a wave power transmission device comprising: a rectangular main body frame part comprising a lower frame, side frames on both sides, and an upper frame; two shaft fixing members installed at regular intervals on the upper surface of the upper frame; through-holes formed at regular intervals in the upper frame; a buoyancy body that moves up and down according to the height of the floor; an up and down motion transmission bar that is connected to the upper end of the buoyancy body and can move up and down by passing through the through-holes when the buoyancy body moves up and down according to wave force; a pair of central shafts that are installed so as to penetrate parallel to a plurality of shaft fixing members; a support part that is connected to both sides of the up and down motion transmission bar using fastening bolts and has a bar-shaped support part and side support plates integrally formed on both sides of the bottom surface of the bar-shaped support part, and an axial rotation protrusion plate that is connected to the support part; A technology has been previously proposed in which the inclined gear part is fixedly installed on the central shaft so as to be engaged with the above-mentioned axial rotation protrusion plate and convert the up-and-down motion into a rotational motion; a pair of single-end gear parts fixedly installed on one end of the central shaft and capable of unidirectional rotation using the rotational force of the central shaft; a rotating generator gear body installed between the single-end gear parts and coupled to one side of the central rotation axis of the generator to receive the rotational force of the single-end gear part; a generator coupled to the other side of the central rotation axis of the rotating generator gear body; and an elastic body installed on the bottom of the axial rotation protrusion plate; thereby enabling the inclined gear part to rotate in one direction. However, due to the characteristic of the buoyant body moving up and down due to longitudinal wave energy, there is a limitation in that transverse wave energy cannot be utilized.

[0005] In addition, looking at the previously disclosed oscillating column wave power generation technology, Korean Patent No. 10-2137086, includes a water column including an inlet portion into which water is introduced by waves and an air compression portion provided on the upper portion of the inlet portion; a wave power generator including an inlet pipe connected to one side of the air compression portion and into which air from the air compression portion is introduced, and a turbine provided in the inlet pipe and generating power; and an artificial structure installed on the seabed at a predetermined distance from the wave power generator and including an inclined portion having an upward slope with respect to the direction of travel of the waves; wherein the inclined portion is configured as a convex inclined surface configured to be convex on one side, and the artificial structure is installed on the inner bottom surface of the water column, and the artificial structure includes a protective film provided on the outer surface, wherein the protective film includes a permeation layer in contact with the outer surface of the artificial structure, a heating layer provided on the upper portion of the permeation layer, and a protective layer provided on the upper portion of the heating layer. However, there was a problem that continuous power generation was impossible in an environment where the difference between high and low tide was large.

[0006] The present invention is a new technology that was created to solve various problems of the above-mentioned conventional technology, and the problem to be solved in the invention is to provide a wave power generation device that responds to tidal fluctuations by improving the structure so that the height of the seawater guide pipe can be varied in a flexible manner in response to changes in the sea surface level according to the tidal difference, thereby enabling wave power generation to be uniformly continued even in an environment with a large tidal difference.

[0007] In addition, the purpose is to provide a wave power generation device that responds to tidal fluctuations, in which the seawater induction pipe is arranged at an angle to flexibly absorb the longitudinal and transverse wave energy of the seawater flowing in, thereby improving durability against seawater collision resistance and improving power generation efficiency by comprehensively utilizing the longitudinal and transverse wave energy of the seawater for wave power generation.

[0008] To achieve this purpose, the present invention is characterized by including a foundation structure (10) that is installed upright with a pile member (11) driven into the seabed; a leveling structure (20A) that is installed on the foundation structure (10) and whose height is adjusted in response to changes in the sea surface level due to the difference between high and low tides; and a seawater guide pipe (30) that is installed on the leveling structure (20A) and has an inclined channel (31) formed with one end submerged in seawater and the other end exposed above the sea surface, and is provided to drive a wave power generator (100) by comprehensively utilizing longitudinal and transverse wave energy of seawater moving at an inclined angle along the inclined channel (31).

[0009] At this time, the leveling structure (20A) is characterized by including a truss structure formed and having a truss body (22) provided with an inclined plate (21) so that a seawater guide pipe (30) is mounted on the upper portion, a resistance plate (23) arranged longitudinally so as to be submerged in the sea surface at the lower portion of the truss body (22), a buoyancy body (24) provided in an internal space of the truss body (22) to buoy the leveling structure (20A) including the truss body (22) by buoyancy, and a transfer block (25) installed on the truss body (22) and the resistance plate (23) (23') and guided by the foundation structure (10) to guide the longitudinal movement of the leveling structure (20A).

[0010] In addition, it is characterized by forming a weight member (26) on the upper side of the truss body (22) higher than the sea level so as to control the buoyancy height of the leveling structure (20A).

[0011] In addition, the above-mentioned foundation structure (10) is characterized by including a support member (12) formed to surround the outer surface of a pile member (11) so as to be supported by the pile member (11) driven into the seabed, and a vertical rail (13) mounted on the support member (12) and formed in a cross-sectional shape of at least one of a 'C' shape and an 'L' shape to guide the longitudinal movement of the transfer block (25).

[0012] In addition, the vertical rail (13) and the support (12) are provided with fastening pieces (14) at opposing positions, and are provided so as to be fastened with bolts while the fastening pieces (14) are in contact with each other, a wedge-shaped slot piece (15) is formed at the lower end of the vertical rail (13), and a slot groove (16) is formed in the support (12) so that the slot piece (15) is inserted downward from the top, and after inserting the slot piece (15) of the vertical rail (13) into the slot groove (16), the fastening piece (14) is fastened with bolts while the vertical rail (13) is in close contact with the support (12), thereby fixing the vertical rail (13).

[0013] In addition, the seawater induction pipe (30) is provided to be fastened to the inclined plate (21) through a support plate (32) installed on the bottom, and the support plate (32) has an inclined projection (32a) formed at a low end, and a fastening hole (32b) for bolt fastening is formed at a high end, and the inclined plate (21) is provided to have an inclined groove (21a) formed at a low end to receive the inclined projection (32a), and is characterized in that the support plate (32) and the inclined plate (21) are fastened with a bolt through the fastening hole (32b) in a state where the inclined projection (32a) is fitted into the inclined groove (21a).

[0014] In addition, the seawater induction pipe (30) is characterized in that a support plate (32) is installed on the bottom surface, and the support plate (32) and the inclined plate (21) are bolted together to allow the seawater induction pipe (30) to be detachably installed.

[0015] In addition, the seawater induction pipe (30) is characterized in that an expansion pipe (33) is installed on the inlet side, and the seawater induction pipe (30) and the expansion pipe (33) are connected to each other by a reinforcing rib (34) mounted on the outer surface.

[0016] Another problem-solving means of the present invention comprises a wave power generation device that responds to tidal fluctuations, comprising: a foundation structure (10) that is erected with a pile member (11) driven into the seabed; a leveling structure (20B) that includes a panel plate (29) installed on the upper part of the foundation structure (10), a winch drive unit (27) that is installed on the panel plate (29) and has a drive rotor that is connected to a drive unit (power source) and rotates in the forward and reverse directions therein, a platform (27a) that is engaged with the drive rotor and is moved in the longitudinal direction by the rotational force of the drive rotor, and an elevator body (28) that is connected to the lower part of the elevator body (27a) and has an inclined compartment (28b) that is open at the upper part to accommodate a seawater induction pipe (30); And it is characterized by including a seawater induction pipe (30) which is installed in the inclined compartment (28b) of the leveling structure (20B), and has an inclined channel (31) formed with one end submerged in seawater and the other end exposed above the sea surface, and is equipped to drive a wave power generator (100) by comprehensively utilizing longitudinal and transverse wave energy of seawater moving at an inclined angle along the inclined channel (31).

[0017] According to a specific means for solving the above-described problem, the present invention has the advantage of being able to sustain stable and continuous wave power generation even in an environment with a large tidal difference, as the structure is improved so that the height of the seawater guide pipe can be varied in response to changes in the sea surface level.

[0018] In addition, since the leveling structure (20A, 20B) and the seawater induction pipe (30) are raised and lowered along the pile member (11) that penetrates the seabed to a sufficient depth, smooth operation can be guaranteed even in the event of a sudden change in water level in bad weather conditions such as a typhoon.

[0019] In addition, the seawater guide pipe is arranged at an angle to flexibly absorb the longitudinal and transverse wave energy of the seawater flowing into the seawater guide pipe, thereby improving durability against seawater collision resistance and comprehensively utilizing the longitudinal and transverse wave energy of the seawater for wave power generation. In addition, the power generation method of the mobile body type and the oscillating water column type can be selectively applied, so there is an effect of promoting improvement in power generation efficiency.

[0030] Hereinafter, the present invention will be described in more detail with reference to specific embodiments of the attached drawings. Throughout the specification, when a part is said to be "connected" to another part, this includes not only cases where it is "directly connected" but also cases where it is "indirectly connected" with another member in between. In addition, expressions indicating directions such as "up, down, front, back" used in the following description are defined based on the drawings, and the shape and position of each component are not limited by these terms.

[0031] Fig. 1 is a perspective view showing a preferred embodiment of a leveling structure in a wave power generation device corresponding to only the tidal current provided in the present invention, Fig. 2 is an exploded perspective view of Fig. 1, and Fig. 3 is a configuration diagram showing Fig. 1 from the side.

[0032] The present invention relates to a wave power generation device that responds to tidal fluctuations, and which is structurally improved to vary the height of a seawater guide pipe in response to changes in the level of the sea surface, so that wave power generation can be uniformly sustained in a marine environment with a large tidal difference, and is largely composed of a base structure (10), a leveling structure (20A, 20B), and a seawater guide pipe (30), and each component is described in detail below.

[0033] The foundation structure (10) according to the present invention is installed so that the pile member (11) is driven into the seabed and the upper part is exposed above the sea surface.

[0034] The above-mentioned foundation structure (10) is fixed to the seabed and guides the longitudinal (up and down) movement of the leveling structure (20A, 20B) described later.

[0035] The leveling structure (20A, 20B) according to the present invention is installed so as to be able to move up and down on the foundation structure (10), and is provided so as to adjust its height in response to changes in the sea level due to the difference between high and low tides.

[0036] The above leveling structure (20A, 20B) can be broadly divided into two types: one can be configured in a way that the height is adjusted using the buoyancy of the buoyancy body (24) and the weight member (26) as shown in FIGS. 1 to 3, or it can be configured to be moved in the up and down direction by the level driving unit (27) as shown in FIGS. 8 to 9.

[0037] The seawater induction pipe (30) according to the present invention is installed in the leveling structure (20A, 20B), and an inclined channel (31) is formed in which one end is submerged in seawater and the other end is exposed above the sea surface, and is provided to drive a wave power generator (100) by comprehensively utilizing longitudinal and transverse wave energy of seawater moving at an inclined angle along the inclined channel (31).

[0038] The above seawater induction pipe (30) has an open lower end to allow seawater to flow in and out. At this time, seawater flowing in through the lower end of the seawater induction pipe (30) can absorb longitudinal and transverse wave energy in a complex manner as it moves at an upward slope. Here, longitudinal wave energy refers to the up-and-down kinetic energy of seawater, and transverse wave energy refers to the left-right kinetic energy of seawater.

[0039] In this way, the longitudinal and transverse collision resistance with seawater is effectively absorbed by the inclination angle of the inclined channel (31), and the longitudinal and transverse wave energy of seawater is comprehensively used to drive the wave power generator (100), so that the power generation method of the mobile body type and the vibrating water column type can be selectively operated, and there is an advantage of improved power generation efficiency.

[0040] Fig. 7 is a schematic diagram showing a state in which an expansion pipe is installed at the inlet of a seawater induction pipe of a power generation device of the present invention. In order to smoothly introduce a greater amount of seawater into the seawater induction pipe (30), an expansion pipe (33) whose internal cross-sectional area gradually expands toward the lower end of the seawater induction pipe (30) can be formed. At this time, the seawater induction pipe (30) and the expansion pipe (33) are provided to be connected to each other by a reinforcing rib (34) mounted on the outer circumferential surface.

[0041] In this way, since the durability of the expansion pipe (33) is secured by the above-mentioned reinforcing rib (34), there is an advantage in that deformation and damage of the expansion pipe (33) due to typhoons and strong waves are prevented.

[0042] Referring to the following Figures 1 to 5, a leveling structure (20A) whose height is adjusted using the buoyancy of a buoyancy body (24) and a weight member will be described.

[0043] The above leveling structure (20A) includes a truss body (22) formed as a truss structure and having an inclined plate (21) provided at the upper portion so that a seawater induction pipe (30) is mounted thereon, upper and lower resistance plates (23)(23') spaced apart longitudinally from each other at the lower portion of the truss body (22) and provided to resist seawater underwater, a buoyancy body (24) provided in the internal space of the truss body (22) and provided to buoy the leveling structure (20A) including the truss body (22) by buoyancy, and a transfer block (25) installed on at least one of the truss body (22) and the upper and lower resistance plates (23)(23') and guided by a foundation structure (10) to guide longitudinal movement of the leveling structure (20A).

[0044] The upper and lower resistance plates (23)(23') above are base members for forming a single leveling structure (20A, 20B) with a plurality of truss bodies (22) and seawater induction pipes (30) arranged in parallel thereon.

[0045] In the drawing, the resistance plates are shown in two places, upper and lower, but they can also be configured as one, and in this case, the resistance plate (23) is installed at the bottom of the truss body (22).

[0046] In addition, it is also possible to configure three or more resistance plates (23), and in this case, the resistance plates (23) are spaced apart at regular intervals, and the resistance plate (23) placed at the bottom is installed at the bottom of the truss body (22).

[0047] The truss body (22) is designed to maintain the seawater guide pipe (30) at a predetermined height while forming a space in which a plurality of buoyancy bodies (24) are installed inside, and is provided to adjust the height of the seawater guide pipe (30) by the buoyancy bodies (24) and the weight member (26) in response to changes in the sea surface level due to the tidal difference while being buoyed by the buoyancy bodies (24).

[0048] Fig. 10 is a configuration diagram showing an example of a weight member in a wave power generation device that responds only to tidal currents of the present invention. The wave power generation device that responds only to tidal currents of the present invention is provided so that the buoyancy height of the seawater guide pipe (30) is adjusted by the buoyancy body (24) and the weight member (26).

[0049] Referring to the enlarged view of Fig. 10, the weight member (26) includes a shaft (26a), a weight (26c) having an axial hole (26b) formed therein so as to be laminated and assembled on the shaft (26a), and a locking member (26d) fastened to the shaft (26a) to restrain the weight (26c).

[0050] In order to enable the field worker to control the buoyancy height of the leveling structure (20A), the weight member (26) is formed on the upper side of the truss body (22) higher than the sea level.

[0051] The above shaft (26a) is installed longitudinally, and is provided so that the floating height of the leveling structure (20A) including the truss body (22) is adjusted according to the number of weights (26c) installed on the shaft (26a).

[0052] Accordingly, considering the total weight of the leveling structure (20A) and the seawater guide pipe (30), the number of weights (26c) to be installed is determined so that the lower part of the seawater guide pipe (30) has an appropriate buoyancy to be submerged in seawater.

[0053] Figure 4 is a schematic diagram showing the basic structure of a wave power generation device that responds to the tidal current of the present invention. The basic structure (10) of the present invention comprises a support member (12) formed to surround the outer surface of a pile member (11) so as to be supported by a pile member (11) driven into the seabed, and a vertical rail (13) that is mounted on the support member (12) in close proximity to the transfer block (25) and is formed in at least one cross-sectional shape of a 'C' shape or an 'L' shape to guide the longitudinal movement of the transfer block (25).

[0054] As an example, the above-mentioned foundation structure (10) may be provided with an 'L'-shaped vertical rail (13) to accommodate an 'L'-shaped transfer block (25) arranged at the corners of the truss body (22) and the upper and lower resistance plates (23) (23'), and further, a 'C'-shaped vertical rail (13) may be provided to accommodate a straight-line transfer block (25) arranged on the straight surface of the truss body (22) and the upper and lower resistance plates (23) (23').

[0055] Figure 5 is a configuration diagram showing the vertical rail installation structure of the power generation device of the present invention, wherein the vertical rail (13) and the support (12) are provided with a fastening piece (14) having a plurality of bolt holes formed at positions facing each other, and are provided so that the fastening pieces (14) are firmly fastened by passing bolts through them while facing each other.

[0056] In order to facilitate the installation of the vertical rail (13), a wedge-shaped slot piece (15) is formed at the lower end of the vertical rail (13), and a slot groove (16) is formed at the lower end of the support (12) so that the slot piece (15) is inserted downward from the top and is in close contact with the support (12).

[0057] At this time, when the slot piece (15) is combined with the slot home (16), the installation heights of the fastening pieces (14) formed on the vertical rail (13) and the support (12) are designed to be the same.

[0058] And, after inserting the slot piece (15) of the vertical rail (13) into the slot home (16), the vertical rail (13) is fixed by fastening the fastening piece (14) with a bolt while the vertical rail (13) is in close contact with the support (12).

[0059] Accordingly, when constructing or replacing the vertical rail (13), there is an advantage in that the lower part of the vertical rail (13) can be assembled in the correct position by connecting the slot piece (15) and the slot groove (16) from outside the water surface without having to deploy a diver.

[0060] FIG. 6 is a schematic diagram showing the installation structure of a seawater induction pipe of a power generation device of the present invention. In FIG. 6 (a), the seawater induction pipe (30) is provided to be fastened to an inclined plate (21) through a support plate (32) installed on the bottom, and the support plate (32) has an inclined projection (32a) formed on a lower end, and a fastening hole (32b) for bolt fastening is formed on a higher end, and the inclined plate (21) is provided to have an inclined groove (21a) formed on a lower end to accommodate the inclined projection (32a).

[0061] Accordingly, the support plate (32) and the inclined plate (21) are bolt-fastened through the fastening hole (32b) while the inclined projection (32a) is fitted into the inclined groove (21a), thereby reducing the number of bolts to be fastened, thereby improving workability for installing and removing the seawater induction pipe (30) and significantly reducing the manpower of the worker.

[0062] In Fig. 6 (b), the seawater induction pipe (30) is provided with a support plate (32) installed on the bottom surface, and the support plate (32) and the inclined plate (21) are bolted together so that the seawater induction pipe (30) can be detachably installed.

[0063] In this way, the seawater guide pipe (30) is installed detachably by the support plate (32) and the inclined plate (21), so that assembly and construction can be done on site, and there is an advantage that the seawater guide pipe (30) can be partially replaced when damaged.

[0064] Fig. 8 is a schematic diagram showing a leveling structure (20B) according to one embodiment of the present invention, and Fig. 9 is a schematic diagram showing the operating state of Fig. 8.

[0065] The above leveling structure (20B) includes a panel plate (29) installed on the upper part of a foundation structure (10), a lifting drive unit (27) installed on the panel plate (29) and having a driving rotor that is connected to a driving unit (power source) and rotates in the forward and reverse directions, a lifting platform (27a) that is engaged with the driving rotor and is moved in the longitudinal direction by the rotational force of the driving rotor, and an lifting body (28) that is connected to the lower part of the lifting platform (27a) and has an inclined compartment (28b) that is open at the upper part to accommodate a seawater induction pipe (30). Here, the foundation structure (10) can be formed of a pile member.

[0066] As shown, the above-mentioned elevator (28) can be configured with a plurality of inclined compartments (28b) arranged in parallel, and at this time, a connecting plate (28a) is formed on the outer side of the inclined compartments (28b) arranged between and at the edges of the inclined compartments (28b) so as to be connected to the lower end of the elevator platform (27a).

[0067] And, as shown, when a rack gear is formed on the elevator (27a), the driving rotation body can be formed as a pinion gear.

[0068] When configured as above, when the driving rotor (pinion gear) rotates in one direction by the power source inside the winch drive unit (27), the lift platform (27a) that is meshed with it moves downward, and when the driving rotor rotates in the opposite direction, the lift platform (27a) moves upward, thereby adjusting the height of the seawater induction pipe (30).

[0069] That is, as illustrated in Fig. 9, the lifting drive unit (27) can control the height of the lifting body (28) and the seawater guide pipe (30) by driving the power source of the lifting drive unit (27) in response to the change in sea level due to the difference in tidal range.

[0070] Meanwhile, the above-mentioned lifting drive unit (27) can be configured to be manually controlled by an administrator or operated by a sensor and timer that detects the sea surface level to remotely adjust the height of the seawater induction pipe (30).

[0071] In Fig. 8, a structure in which three inclined compartments (28b) are formed in the above-mentioned elevator (28) is illustrated, but the structure is not limited thereto, and the number of inclined compartments (28b) can be increased or decreased to configure the application quantity of the seawater induction pipe (30) to be appropriately adjusted.

[0072] Additionally, the above-mentioned inclined chamber (28b) may be configured in the form of a truss structure.

[0073] The above-mentioned tidal wave power generation device is characterized by a configuration in which the height of the seawater guide pipe (30) is adjusted in a simple manner by installing the seawater guide pipe (30) on a leveling structure (20A, 20B) supported by a foundation structure (10) and having a level adjusted therein, thereby enabling extremely efficient recovery and use of wave energy in ocean conditions with a large tidal difference, and is therefore a useful invention with a very high degree of industrial applicability.

[0074] Moreover, since the leveling structure (20A, 20B) and the seawater induction pipe (30) are raised and lowered along the pile member (11) that penetrates the seabed to a sufficient depth, smooth operation can be guaranteed even in the event of a sudden change in water level in bad weather conditions such as a typhoon.

[0075] While the detailed description of the present invention has described the most preferred embodiments thereof, it will be appreciated that various modifications are possible without departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above-described embodiments, but should also extend to the technologies described in the following claims and equivalent technical means derived from these technologies.

[0076] The present invention automatically adjusts the height of the seawater guide pipe to flexibly respond to changes in sea level due to tidal fluctuations, thereby enhancing wave power generation efficiency and enhancing durability, making it applicable to the marine renewable energy industry. Combined with existing marine structure technology, it has significant industrial potential, including the construction of large-scale power plants.
