Description

Wave power generation device with improved durability and energy efficiency

[0001] The present invention relates to a wave power generation device that utilizes longitudinal and transverse wave energy in a complex manner. More specifically, it relates to a wave power generation device that not only provides a function as a breakwater, but also has improved durability and energy efficiency to enhance power generation efficiency by utilizing the kinetic energy of waves.

[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, Patent No. 10-1638734 includes a rectangular main body frame part consisting of 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 perforated 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 is formed integrally with a bar-shaped support part and side support plates 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] Meanwhile, looking at another wave power generation system disclosed in the past, a technology including a floating body having an internal space; a wave power generation device installed inside the floating body; a buoyancy control device installed on the lower side of the floating body to control the buoyancy of the floating body; an attitude control weight installed on the lower side of the buoyancy control device to maintain a constant vertical position of the floating body; a wiring member connected to the attitude control weight; and a fixing unit fixedly installed on the seabed and preventing the floating body from being lost through a connection with the wiring member; has been previously registered in Korean Patent No. 10-1486046. However, this has a problem in that it is highly likely to be lost or damaged by wave energy when bad weather such as a typhoon occurs, as it is a structure in which a fixing device (1500) installed on the seabed and a wave power generation device (100) on the water surface are connected by a chain-like wiring member (1450).

[0006] The present invention solves various problems of the above-mentioned conventional technology and creates a new technology to utilize wave energy, which is a natural clean energy, as stably as possible. The invention aims to provide a wave power generation device with improved durability and energy efficiency that can secure structural safety from waves and typhoons by constructing a foundation structure on the coastal seabed and installing an inclined guide pipe and a wave power generation module thereon.

[0007] In addition, the purpose is to provide a wave power generation device with improved durability and energy efficiency, which can improve durability against seawater collision resistance by flexibly absorbing longitudinal and transverse wave energy of seawater flowing into the inclined flow path by arranging the inclined guide pipe at an angle, and improve power generation efficiency by comprehensively utilizing longitudinal and transverse wave energy of seawater for wave power generation.

[0008] In order to solve the above-described problem of the present invention, as a specific means, a wave power generation device with improved durability and energy efficiency is configured, characterized by including: a foundation structure (10) including pile members (11) spaced apart from each other at different heights while being driven into the seabed, and a reinforcing member (12) that connects the pile members (11) to each other; an inclined plate (20) installed on the upper end of the pile member (10) and arranged to be aligned in a straight line at an inclined angle; and an inclined guide pipe (30) installed on the inclined plate (20), having an inclined channel (31) formed such that one end is submerged in seawater and the other end is exposed above the sea surface, and driving a wave power generation module (100) by comprehensively utilizing longitudinal and transverse wave energy of seawater moving at an inclined angle along the inclined channel (31).

[0009] In another embodiment of the present invention, a wave power generation device having improved durability and energy efficiency is configured, comprising: a foundation structure (10) including pile members (11) spaced apart from each other at different heights while being driven into the seabed, and a reinforcing member (12) connecting the pile members (11) to each other; an inclined plate (20) installed on the upper portion of the pile member (10) and arranged to be aligned in a straight line at an inclined angle; a base stage (40) installed on the inclined plate (20) and arranged at an inclined angle, and having a support holder (41) provided on the upper surface to receive a nut (N) for fastening a bolt (B); And it is characterized by including an inclined guide pipe (30) which is fixed by a bolt (B) and a nut (N) while being secured to a support holder (41) of the base stage (20), and which has an inclined channel (31) formed with one end submerged in seawater and the other end exposed above the sea surface, and which is equipped to drive a wave power generation module (100) by comprehensively utilizing longitudinal and transverse wave energy of seawater moving at an inclined angle along the inclined channel (31).

[0010] In addition, the inclined guide tube (30) is characterized by being formed as a square tube or a circular tube.

[0011] In addition, in order to introduce a larger amount of seawater into the inclined flow path (31), a hopper pipe (32) is formed whose internal cross-sectional area gradually expands toward the lower end of the inclined guide pipe (30), and the hopper pipe (32) is formed to be mounted on the base stage (40) together with the inclined guide pipe (30).

[0012] In addition, it is characterized in that a floating bridge (60) is installed on the above-mentioned foundation structure (10) and is exposed above the sea surface to form a passageway for workers to move.

[0013] In addition, the wave power generation module (100) is characterized by including a buoyancy body (110) that is accommodated in an inclined channel (31) and moves linearly at an inclined angle by longitudinal and transverse wave energy while floating on seawater, and a generator (120) that converts the linear motion of the buoyancy body (110) into rotational motion to generate electric energy.

[0014] In addition, the wave power generation module (100) is characterized by including an opening (130) formed at a high end of an inclined channel (31) and outputting compressed air compressed by longitudinal and transverse wave energy within the inclined channel (31), and a generator (120) that generates electric energy by being rotated by the compressed air output through the opening (130).

[0015] In addition, several sliding guides (34) are formed in the longitudinal direction inside the inclined guide tube (30) to reduce the contact area with the buoyancy body (110) and minimize frictional resistance, and a scraper (112) is further formed in the circumferential direction of the buoyancy body (110) to prevent foreign substances including seaweed flowing into the inclined guide tube (30) from sticking inside.

[0016] In addition, the lower end of the guide rail (44) is formed with an inner groove (46) by a blocking plate (45) connecting the guide rails (44), and the slide body (36) is formed with a connecting projection (37) that is fitted to the inner groove (46).

[0017] According to a specific means for solving the above-described problem, the present invention constructs a foundation structure including a pile on the seabed of the coast, installs an inclined guide pipe and a wave power generation module thereon, and improves the structure of the foundation structure to increase durability by increasing its resistance to external forces such as wave power or typhoons, thereby ensuring structural safety from waves and typhoons.

[0018] In particular, the inclined guide pipe is arranged at an angle to flexibly absorb the longitudinal and transverse wave energy of seawater flowing into the inclined guide pipe, thereby improving durability against seawater collision resistance and improving power generation efficiency by comprehensively utilizing the longitudinal and transverse wave energy of seawater for wave power generation.

[0019] In addition, if a hopper pipe is installed at the lower end of the inclined guide pipe, more seawater flows into the inclined guide pipe through the hopper pipe, which has the effect of improving power generation efficiency.

[0020] Additionally, when installed offshore, it has the advantage of functioning as a breakwater to protect villages or buildings adjacent to the sea.

[0021] In addition, the generator that constitutes the wave power generation module can be directly connected to the end of the inclined guide pipe or installed on land, so it can be configured variably depending on the installation environment or location conditions.

[0047] Hereinafter, the present invention will be described in more detail with reference to specific embodiments of the attached drawings. The technical terms used in this specification are terms selected in consideration of functions in the embodiments, and the meanings of the terms may vary depending on the specific embodiments of the invention. In addition, 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.

[0048] FIG. 1 is a schematic diagram showing a preferred embodiment of a wave power generation device with improved durability and energy efficiency provided by the present invention, and FIG. 2 is a longitudinal cross-sectional view showing the inclined guide pipe installation structure of FIG. 1.

[0049] The present invention relates to a wave power generation device with improved durability and energy efficiency, which comprises a basic structure (10), an inclined plate (20), and an inclined guide pipe (30) configured to provide structural safety from waves and typhoons by constructing a foundation structure on the seabed of a coast and installing an inclined guide pipe and a wave power generation module thereon, and at the same time, the inclined guide pipe is arranged at an inclined angle to flexibly absorb longitudinal and transverse wave energy of seawater flowing into the inclined flow path, thereby improving durability against seawater collision resistance and improving power generation efficiency by comprehensively utilizing longitudinal and transverse wave energy of seawater for wave power generation. Each component is described in detail below.

[0050] First, the foundation structure (10) according to the present invention includes pile members (11) spaced apart from each other at different heights while being driven into the seabed, and reinforcing members (12) that connect the pile members (11) to each other.

[0051] The above-mentioned foundation structure (10) is configured to support the inclined guide pipe (30) described later, and as shown in FIG. 1, pile members (11) are installed standingly at a predetermined interval, and neighboring reinforcing members (12) are connected to each other in the transverse and diagonal directions by the pile members (11) in a truss structure, so as to maintain integrity and increase resistance to external forces such as wave force or typhoons, thereby ensuring durability.

[0052] In this way, since the above-mentioned foundation structure (10) is formed by a combination of pile members (11) and reinforcing materials (12), there is an advantage in that structural safety is secured from waves and typhoons.

[0053] The inclined plate (20) according to the present invention is fixed to the upper part of the pile member (10) and is arranged to be inclined at a predetermined angle, but is formed to be aligned in a straight line with each other.

[0054] The above-mentioned inclined plate (20) is configured to support the inclined guide tube (30) described later at an inclined angle from below as shown in FIG. 2, and a plurality of fastening holes for fastening bolts and nuts are formed through it.

[0055] The inclined guide pipe (30) according to the present invention is installed on the inclined plate (20), and an inclined flow path (31) is formed in which one end is submerged in seawater and the other end is exposed above the sea surface.

[0056] That is, the inclined guide tube (30) is positioned so that the inclined flow path (31) is formed at an inclined angle as it is fixed and secured to the inclined plate (20), and the lower section is partially submerged in seawater.

[0057] Accordingly, seawater flowing in through the lower side of the inclined channel (31) can absorb longitudinal and transverse wave energy in a complex manner as it moves at an inclined angle. Here, longitudinal wave energy refers to the up-and-down kinetic energy of seawater, and transverse wave energy refers to the kinetic energy of seawater waves.

[0058] In this way, the wave power generation module (100) is driven by using the longitudinal and transverse wave energy of seawater flowing into the inclined channel (31) in a complex manner due to the inclination angle of the inclined channel (31), so that various types of power generation methods can be selectively operated, and there is an advantage of improved power generation efficiency.

[0059] FIG. 3 is a schematic diagram showing the overall structure of a wave power generation device with improved durability and energy efficiency according to another embodiment of the present invention, and FIG. 4 is a longitudinal cross-sectional view showing the inclined guide pipe installation structure of FIG. 3.

[0060] A wave power generation device with improved durability and energy efficiency according to another embodiment of the present invention is composed of a main component including a base structure (10), an inclined plate (20), an inclined guide pipe (30), and a base stage (40).

[0061] Compared to Fig. 1, it is characterized by the fact that a base stage (40) is additionally configured between the inclined plate (20) and the inclined guide tube (30).

[0062] According to FIGS. 3 and 4, the inclined plate (20) fixed to the upper part of the file member (10) is configured to support the base stage (40) at an inclined angle, and a plurality of fastening holes for fastening bolts and nuts are formed through it.

[0063] Also, referring to FIG. 4, the base stage (40) according to the present invention is installed on the inclined plate (20) and arranged at an inclined angle, and is provided with a support holder (41) for bolting connection with the inclined guide tube (30) installed on the upper portion.

[0064] The above base stage (40) is supported by a plurality of inclined plates (20), and a grid-shaped rib for structural reinforcement can be formed on the bottom surface.

[0065] At this time, the support holder (41) formed in parallel and spaced apart on the upper portion of the base stage (40) is formed with a space (42) that can accommodate a nut (N) inside, as shown in Fig. 4. At this time, the space (42) can be formed so that the outside is open so that the nut can be easily loosened or locked using a tool or the like on the outside.

[0066] Accordingly, the inclined guide tube (30) fastened by a bolt (B) and a nut (N) while being secured to the support holder (41) of the base stage (20) can be protected from the external environment by the support holder (41) so that the fastening state with the inclined guide tube (30) can be stably maintained for a long time, and also has the advantage of providing convenience in installation work when the inclined guide tube (30) is connected to the base stage (40).

[0067] FIG. 5 is a configuration diagram showing a modified example of an inclined guide pipe of a wave power generation device with improved durability and energy efficiency according to one embodiment of the present invention.

[0068] The above-mentioned inclined guide tube (30) may be formed as a square tube as in Fig. 5 (a) or as a circular tube as in Fig. 5 (b).

[0069] When the above-mentioned inclined guide pipe (30) is formed as a circular pipe, it is provided to be restrained on the inclined plate using a U-shaped fastening member.

[0070] Meanwhile, as shown in FIGS. 1 and 5 (c) and (d), in order to amplify the seawater pressure by introducing a larger amount of seawater into the inclined flow path (31), a hopper pipe (32) whose internal cross-sectional area gradually expands toward the lower end of the inclined guide pipe (30) can be formed. At this time, the hopper pipe (32) is formed to be mounted on the base stage (40) together with the inclined guide pipe (30).

[0071] In this way, if a hopper pipe (32) is installed at the lower end of the inclined guide pipe (30), more seawater flows into the inclined guide pipe through the hopper pipe, which has the effect of improving power generation efficiency and dispersing wave energy.

[0072] Figure 6 is a schematic diagram showing an example of a wave power generation device according to the present invention in which a hopper tube is formed at one end of an inclined guide tube. When waves impact the inner wall of the hopper tube (32) that protrudes from the inflow end of seawater, the load is concentrated at the connection between the hopper tube (32) and the inclined guide tube (30), which may result in damage.

[0073] To overcome this, as shown in the drawing, by installing a reinforcing beam (70) composed of a vertical member (72) installed on a base stage (40) and a horizontal member (74) intersecting the vertical member (72) and connected to the hopper pipe (32), the structural safety and durability of the hopper pipe (32) and the inclined guide pipe (30) can be improved.

[0074] At this time, the hopper pipe (32), inclined guide pipe (30), and reinforcing beam (70) installed on the base stage (40) are assembled on land, and then moved to the pre-constructed foundation structure (10) using a barge or land transportation vehicle, and then the base stage (40) is simply connected to the inclined plate (20) using a crane, thereby simplifying the installation process.

[0075] Referring to FIGS. 1 and 3, the wave power generation device provided in the present invention may be equipped with a marker light (50) that is exposed above the sea surface and outputs a light source to indicate the construction location of the foundation structure (10) or the location of the wave power generation device.

[0076] The above-mentioned sign light (50) is installed at a position adjacent to the high side end of the inclined guide pipe (30).

[0077] In this way, there is an advantage in that the location of the wave power generation device of the present invention can be identified at night and at a long distance by the light source output from the above-mentioned indicator light (50), thereby preventing damage and safety accidents caused by collision with vessels sailing in the vicinity.

[0078] Fig. 7 is a plan view illustrating a state in which a plurality of wave power generation devices of the present invention are formed in parallel. Referring to Figs. 3 and 7, a floating bridge (60) is installed on the foundation structure (10) and is exposed above the sea surface to form a passageway for workers to move.

[0079] The above-mentioned bridge (60) is preferably installed at a location adjacent to the high side end of the inclined guide pipe (30), and may be formed to be connected to a breakwater or land for the safe movement of workers, and at this time, railings may be installed on both sides.

[0080] Accordingly, workers can safely perform equipment inspection and maintenance work while moving using the passageway formed by the above-mentioned bridge (60).

[0081] Meanwhile, when installed offshore, it has the advantage of functioning as a breakwater to protect buildings or villages adjacent to the sea.

[0082] FIG. 8 is a schematic diagram showing a power generation module of a wave power generation field that comprehensively utilizes longitudinal and transverse wave energy according to an embodiment of the present invention. FIG. 8 (a) is shown as a mobile body type, and FIG. 8 (b) is shown as a vibrating column type.

[0083] In Fig. 8 (a), the wave power generation module (100) includes a buoyancy body (110) that is accommodated in an inclined channel (31) and moves linearly at an inclined angle by longitudinal and transverse wave energy while being buoyed by seawater, and a generator (120) that converts the linear motion of the buoyancy body (110) into rotational motion to generate electric energy.

[0084] That is, as the buoyancy body (110) is moved at an angle by the seawater moving at an angle along the inclined channel (31), the buoyancy body (110) can move in a straight line regardless of the direction of the seawater, whether it is longitudinal or transverse, and thus can absorb wave energy in a complex manner. At this time, the buoyancy body (110) is connected to drive a generator (120) by a power transmission means.

[0085] At this time, the generator (120) is not directly connected to the end of the inclined guide pipe (30), and can also be configured to be installed on land.

[0086] In Fig. 8 (b), the wave power generation module (100) is formed at the high side end of the inclined channel (31), and includes an opening (130) that outputs compressed air compressed by longitudinal and transverse wave energy within the inclined channel (31), and a generator (120) that generates electric energy by being rotated by the compressed air output through the opening (130).

[0087] The above opening (130) is provided so that air is moved to the generator within the inclined flow path (31) by seawater pressure, and the turbine is rotated by the air pressure moving through the opening (130) to drive the generator (120).

[0088] At this time, the generator (120) is not directly connected to the end of the inclined guide pipe (30), and can also be configured to be installed on the land side.

[0089] In the present invention, since the inclined flow path (31) is formed at an angle with respect to the sea surface, the power generation efficiency of the generator (120) can be improved by utilizing the air pressure generated by the complex wave energy regardless of whether the movement of the sea water is in the longitudinal or transverse direction.

[0090] The specific configuration of the power generation module that uses air pressure as an energy source utilizes existing principles, so a detailed description is omitted.

[0091] Fig. 9 is a state diagram illustrating another embodiment of a wave power generation device to which a wave power generation module utilizing a buoyancy body is applied. As illustrated, when a buoyancy body (110) is applied and reciprocates within an inclined flow path (31) of an inclined guide pipe (30), seaweed and the like introduced by waves may interfere with the smooth operation of the buoyancy body (110).

[0092] To overcome this, several sliding guides (34) are formed in the longitudinal direction inside the inclined guide tube (30) to reduce the contact area with the buoyancy body (110) and minimize frictional resistance, and a scraper (112) may be formed in the circumferential direction of the buoyancy body (110) to prevent foreign substances including seaweed flowing into the inclined guide tube (30) from becoming stuck inside.

[0093] The above scraper (112) can be formed on the upper and lower sides of the buoyancy body (110), and at this time, the direction of the blade is formed in opposite directions.

[0094] Accordingly, as shown in Fig. 9(b), when the buoyancy body (110) descends, the scraper (112) formed around the lower side can prevent seaweed or barnacles that may be carried into the inclined channel (31) by waves from adhering to the inner wall of the inclined guide pipe (30).

[0095] Fig. 10 shows an example of a scraping module (80) for preventing foreign substances including seaweed flowing into an inclined guide pipe (30) from sticking inside a wave power generation device to which a wave power generation module using compressed air is applied.

[0096] The above scraping module (80) is composed of a ring-shaped buoy (84) having a shape corresponding to the internal cross-sectional shape of the inclined guide pipe (30) so as to slide along the internal wall of the inclined guide pipe (30) by waves, and a scraper blade (82) formed at least at one of the front and rear portions of the buoy (84).

[0097] At this time, the scraper blade (82) is also configured in a ring shape so as to be close to the inner surface of the inclined guide pipe (30), thereby preventing seaweed or barnacles from adhering to the inner wall of the inclined guide pipe (30) by the scraping module (80) floating on the waves.

[0098] FIG. 11 is an exploded perspective view showing another embodiment of installing an inclined guide pipe on a base stage in a wave power generation device of the present invention, and FIG. 12 illustrates a cross-sectional configuration diagram of FIG. 11, which is an embodiment for providing improved installation convenience when constructing a foundation structure on the seabed and installing an inclined guide pipe and a wave power generation module thereon.

[0099] A pair of guide rails (44) are configured to protrude side by side on both sides of the upper portion of the base stage (40) arranged at an inclined angle, and these guide rails (44) are configured to slide and couple the inclined guide tube (30) described later.

[0100] At the lower end of the above guide rail (44), an inner groove (46) is formed by a blocking plate (45) connecting the guide rails (44).

[0101] And, at the lower part of the inclined guide tube (30), a slide body (36) is formed that is inserted between the guide rails (44) and is secured to the base stage (40) and fastened by a bolt (B) and a nut (N), and at the upper part, an inclined guide channel (31) is formed in which one end is submerged in seawater and the other end is exposed above the sea surface.

[0102] On one side of the above slide body (36), a joining projection (37) corresponding to the shape of the inner groove (46) may be formed so that it can be fitted to the inner groove (46).

[0103] According to the above configuration, when installing the inclined guide pipe (30) on the base stage (40) installed on the foundation structure (10), there is an advantage in that a sturdy installation can be quickly and easily accomplished by only bolting the high end of the base stage (40) and slide body (36) exposed to the water without the need for tying work under the water depth.

[0104] The wave power generation device of the present invention, which is configured as described above and has improved durability and energy efficiency, secures structural safety from waves and typhoons by constructing a foundation structure on the seabed of the coast and installing an inclined guide pipe and a wave power generation module thereon, and utilizes longitudinal and transverse wave energy of the seawater in a complex manner for wave power generation to improve power generation efficiency, so it has very high potential for industrial use.

[0105] 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.
