Description

Wave power generation system using wave power amplification breakwater and construction method thereof

The present invention relates to a wave power generation system and a construction method thereof, and more particularly, to a wave power generation system using a wave power amplification breakwater used for wave power generation by amplifying wave power using a wave power amplification breakwater.

Tetrapod (TTP), which is widely used to construct a breakwater, is suitable for installing a breakwater (sloping agent) in the form of an inclined toward the open sea. A breakwater constructed using a tetrapod is not suitable for building a wave power generation system because it disperses and absorbs waves.

In order to establish a wave power generation system on a breakwater, a direct-walled breakwater (upright) must be installed toward the open sea into which waves flow, and a wave power generation device must be installed on the installed breakwater to face the open sea.

The breakwater should be installed in consideration of the direction of the wave inflow so that the wave can always flow in a certain direction. In addition, wave power generation devices provided on the breakwater must be installed at regular intervals so as not to interfere with each other.

Such a conventional wave power generation system has three problems.

The first is that some of the waves flowing toward the breakwater drive the wave power generation device to contribute to power generation, but the waves flowing between adjacent wave power generation devices cannot drive the wave power generation device and are reflected or extinguished by hitting the breakwater.

In other words, power generation efficiency is very low because power generation is performed using only a small portion of the waves flowing in from the open sea.

In order to solve such a problem, if a wave power generation device is installed that tightly covers the surface of the wave inflow, the structure of the wave power generation system becomes too complex, maintenance is difficult, and it takes a lot of cost to construct a wave power generation system. Occurs.

The second is that the wave power generation device is designed in consideration of the situation in which the wave flows in the front toward the wave power generation device, so if the inflow direction of the wave is not constant, the power generation efficiency decreases, and the wave power generation device may be damaged by the wave incident at an angle. will be.

Conventional wave power generation devices are generally designed to face the inflow direction of the waves. That is, by arranging the rotation axis of the floating body parallel to the incident surface of the wave, the floating body moves up and down only on the wave incident to the front so that the kinetic energy of the wave can be effectively transmitted.

If the incidence direction of the wave is changed, the rotation axis of the floating body and the incident surface of the wave are twisted, so energy of the wave cannot be effectively transmitted, and the rotation axis of the floating body or the floating body may be damaged by the wave.

Third, the wave power generation device must be installed at a location where waves with high wave energy are formed in order to increase the efficiency of wave power generation, but there is a problem that the size of the breakwater must be enlarged in order to withstand the waves with high wave power. .

The present invention was conceived to solve the problems of the prior art as described above, and wave power generation using a wave power amplification breakwater capable of amplifying wave power by concentrating waves flowing in from the open sea to a specific area and enabling wave power generation using this I would like to present a system.

In addition, it is intended to present a wave power generation system with a wave power amplifying breakwater that can withstand waves with high wave power while being installed on a smaller scale to increase economic efficiency.

(2) Concrete block assembly formation step

A plurality of concrete blocks (110, 120, 130, 140) produced in the concrete block manufacturing step are installed on the upper part of the underwater ground 1 as shown in FIGS. 6 and 7, and a plurality of concrete blocks as shown in FIGS. 6 and 7 (110, 120, 130, 140) form a concrete block assembly 100 that is continuously arranged in the horizontal direction and the vertical direction.

6 is a perspective view of the installed state, and FIG. 7 is a cross-sectional view of the installed state.

At this time, the 1-1 concrete blocks 110 and the 1-2 concrete blocks 120 are alternately disposed in the horizontal direction to form the first block layer 100a. When the 1-1 concrete block 110 and the 1-2 concrete block 120 are arranged in a horizontal direction, the 1-1 inclined part 111 and the 1st inclined part 111 and the 1st inclined part 111 and the 1st inclined part 111 The 1-2 inclined portions 121 are connected in a zigzag shape to form the protruding portion 11 and the concave portion 12 of the wave power amplifying breakwater 10.

The second block layer 100b is formed by alternately disposing the 2-1 concrete blocks 130 and the 2-2 concrete blocks 140 in the horizontal direction. When the 2-1 concrete block 130 and the 2-2 concrete block 140 are continuously arranged in the horizontal direction, the 2-1 protruding inclined portion 131 and the front surface of the formed second concrete block 100b The 2-2 concave inclined portion 141 is connected in a zigzag shape so that the protrusion 11 and the concave inlet 12 of the wave power amplifying breakwater 10 are repeatedly formed.

The first block layer 100a and the second block layer 100b are alternately stacked in the vertical direction to form the concrete block assembly 100.

In addition, the first block layer 100a and the second block layer 100b have the same structure in plan view.

Therefore, the concrete block assembly 100 guides the waves incident from the open sea between the first protrusion and the first concave portion to the first concave portion as the first protrusion protruding forward and the first concave concave in the rear are formed alternately. In order to do so, first wave guide portions inclined from the first protrusion toward the first concave portion are formed, respectively. The structure of the concrete block assembly 100 corresponds to the structure of the protrusion 11, the concave inlet 120, and the wave guide 13 of the wave power amplifying breakwater 10.

The 1-1,1-2,2-1,2-2 vertical through- holes 112, 122, 132, 142 of the concrete blocks 110, 120, 130, 140 constituting the concrete block assembly 100 are While continuing in the vertical direction, the lower end is blocked by the underwater ground 1, and the upper end is opened to form a through hole 101 for a concrete column extending in the vertical direction.

That is, any one 1-1 vertical through hole 112 is continuous with the 2-2 vertical through hole 142 at the bottom and the 2-2 vertical through hole 142 at the top, Forming the study 101, the other 1-1 up-down through hole 112 is the second through the bottom 2-1 up-down through hole 132 and the upper 2-1 up-down through hole 132 While continuing to form a through hole 101 for the concrete column.

The underwater ground (1) of this embodiment corresponds to an underwater ground that is not artificially created, that is, the sea floor, but according to the embodiment, the underwater ground (1) is a concept including a foundation ground artificially formed for an underwater concrete block structure. .

If the foundation ground is formed on the upper part of the underwater ground (1) and the concrete block assembly 100 is formed thereafter, a foundation ground construction step of forming the foundation ground before the concrete block assembly formation step is further required.

The foundation ground may be any one or a combination of the ground sandstone ground, the substituted sandstone ground, the deep mixed ground ground, the soft ground improvement ground ground.

When the ground is soft and the necessary support cannot be obtained, the ground is replaced according to the replacement method, consolidation method, dewatering method, drainage method, vibration compaction method, compaction sand pile method, blasting method, chemical injection method, etc. It refers to the ground that has been improved according to the improved soft ground improvement method.

(3) Ground perforation formation step

After the step of forming the concrete block assembly, as shown in FIG. 8, the underwater ground 1 located under the through hole 101 for the concrete column is drilled, and the ground hole 102 is a space continuous with the through hole 101 for the concrete column. To form.

In this embodiment, the protective pipe 103 in the form of extending in the vertical direction is inserted into the underwater ground 1 in the vertical direction through the through hole 101 for the concrete column, while being located under the through hole 101 for the concrete column. Drill the underwater ground (1).

When the ground perforation part 102 is formed in this way, the inserted protective pipe 103 is located across the through hole 101 for the concrete column and the ground perforated part 102, and the ground perforated part ( 102) is formed.

At this time, the protective pipe 103 has a diameter smaller than that of the through hole 103 for a concrete column, and the ground perforation 102 extends in the vertical direction with a cross-sectional area smaller than the cross-sectional area of the through hole 101 for a concrete column.

At this time, the protective pipe 103 prevents the surrounding underwater ground 1 from collapsing into the ground drilling portion 102 during or after the drilling operation, or various foreign substances from flowing into the ground drilling portion 102.

In addition, the protective tube 103 serves to protect the waterproof membrane when inserting the vertical reinforcing bars and the waterproof membrane to be described later.

The length of the protective pipe 103 is preferably formed to be longer than the sum of the length of the through hole 101 for the concrete column and the length of the ground perforation 102. Accordingly, the waterproof membrane insertion operation can be easily performed.

That is, as shown in FIG. 8, the upper surface of the concrete block assembly 100 is positioned higher than the water surface, and the upper end of the protective tube 103 inserted in the ground perforation formation step protrudes from the upper surface of the concrete block assembly 100 Has been. That is, the upper end of the protective tube 103 is positioned higher than the water surface and is positioned higher than the upper surface of the concrete block assembly 100. Therefore, the operation of inserting a waterproof film or the like into the protective tube 103 can be performed very easily.

Meanwhile, the protective tube 103 is preferably removed after the step of forming the ground perforation.

Meanwhile, a drilling equipment is required for drilling the underwater ground (1), and in this embodiment, since the upper surface of the concrete block assembly 100 is located higher than the water surface, the drilling equipment is the upper part of the concrete block assembly 100 If it is placed on the surface to perform drilling, it becomes a dry operation (that is, the wet operation on a barge becomes unnecessary), and working in the same environment as the land operation can increase work efficiency.

(4) Concrete pillar formation stage

After the ground perforation forming step, the concrete pillar 200 is formed along the through hole 101 for the concrete pillar and the ground perforation 102.

The step of forming a concrete column in this embodiment is performed in stages as shown in FIGS. 9 to 12.

First, as shown in Figs. 9 and 10, the vertical reinforcement portion 201 formed in the vertical direction is inserted into the through hole 101 and the ground perforation 102 for a concrete column.

In this embodiment, since the protective pipe 103 is already located in the through hole 101 and the ground perforation 102 for the concrete column, the vertical reinforcement portion 201 is inserted into the protective pipe 103.

At this time, the bottom and side portions of the vertical reinforcing bar portion 201 are wrapped with a waterproof membrane 202 and inserted into the through hole 101 and the ground perforation 102 for a concrete column.

Meanwhile, since the waterproof membrane 202 or the like is inserted through the protective tube 103, there is no risk of being torn or damaged while the waterproof membrane 202 contacts the underwater ground 1 or the like.

In this way, after the vertical reinforcement portion 201 wrapped with the waterproof membrane 202 is inserted into the protective tube 103, concrete 203 is poured into the waterproof membrane 202 as shown in FIGS. 11 and 12 To form a concrete column 200.

11 is a view of a state in which the protective pipe 103 is slightly raised while a small amount of concrete 203 is poured into the waterproof membrane 202.

That is, in FIG. 11, the lower end of the protective pipe 103 is in a state in which the protective pipe 103 is raised to have a state just out of the ground perforation 102, and the inside of the waterproof membrane 202 is in the ground perforation 102 area. The necessary concrete 203 is poured.

Accordingly, the waterproof membrane 202 located in the ground perforation 102 is in close contact with the underwater ground 1 by the pressure of the concrete 203.

In this way, the concrete 203 is gradually poured into the waterproof membrane 202 and the protective tube 103 is gradually raised, and the protective tube 103 is finally completely removed as shown in FIG. The work of pouring concrete 203 in the entire through hole 101 for the column and the ground hole 102 is completed.

That is, the protective tube 103 may be removed before the poured concrete 203 is cured.

In this way, when the concrete 203 is poured into the waterproof membrane 202, the waterproof membrane 202 is in close contact with the underwater ground 1 and the concrete blocks 110, 120, 130, 140 by the pressure of the concrete 203. Afterwards, it becomes a concrete column 200 through a curing process.

If the concrete 203 is poured into the waterproof membrane 202 at once, and then the protective tube 103 may be raised to remove the protective tube 103, in this case, the waterproof membrane 202 is applied under the pressure of the concrete 203. It may be difficult to separate the protective tube 103 from the waterproof film 202 because it is strongly adhered to the inside of the protective tube 103.

In this way, the concrete column 200 is formed in the concrete block assembly 100.

That is, the concrete pillar 200 is positioned in the first concrete pillar portion 200a extending in the vertical direction with the first diameter while being positioned in the through hole portion 101 for the concrete pillar, and the second diameter while being positioned in the ground perforation portion 102 It consists of including a second concrete column portion (200b) extending in the vertical direction.

In this way, a plurality of concrete blocks (110, 120, 130, 140) constituting the concrete block assembly (100) is in a state bound to the underwater ground (1) by the concrete column (200).

Therefore, in order to evaluate the stability of the concrete block assembly 100 of this embodiment, in addition to the weight of the concrete block assembly 100 and the frictional force on the underwater ground 1 of the underwater concrete block structure 200, the concrete column 200 ) To the underwater ground (1) must be considered together.

That is, the concrete block assembly 100 has a remarkably improved stability due to the binding force to the underwater ground 1 by the concrete column 200.

That is, even in the case of a relatively compact structure, it is possible to implement the wave power amplifying breakwater 10 capable of responding to waves of high wave power energy.

(5) Steps of forming a standing concrete structure

After the step of forming the concrete pillar, as shown in FIG. 13, a standing concrete structure 300 is formed on the upper part of the concrete block assembly 100.

The plan view structure of the standing concrete structure 300 corresponds to the plan view structure of the concrete block assembly 100.

That is, the standing concrete structure 300 guides the waves incident from the open sea between the second protrusion and the second concave portion to the second concave portion as the second protrusion protruding forward and the second concave concave in the rear are formed alternately. In order to do so, a second wave guide portion inclined toward the second concave portion from the second protrusion portion is formed, respectively, and the structure of the standing concrete structure 300 is the protrusion 11, the concave portion 120 of the wave power amplifying breakwater 10, Corresponds to the structure of the wave guide 13.

The stand-up concrete structure 300 is to make the upper part of the wave power amplifying breakwater 10 a hydrophilic space or to be utilized as a space for installation of facilities such as a lighthouse.

As the concrete structure 300 is formed in this way, the wave power amplifying breakwater 10 is completed.

In the wave power amplifying breakwater 10, concave portions 12 are repeatedly formed at about 12m intervals. A wave power generating device installation space 12a for installing the wave power generating device 20 is formed on the upper side of the concave inlet 12.

Wave power generating device installation space (12a) is formed in the shape of a concave inward groove. In addition, a step 12b is formed on the upper side of the wave power amplifying breakwater 10 to access the wave power generation device installation space 12a. Additional structures such as the staircase 12b may be omitted or changed to other structures depending on the embodiment.

In this embodiment, the wave power generation device installation space 12a is formed in the standing concrete structure 300. The location of the wave power generating device installation space 12a may be changed according to a height protruding above the water surface of the wave power amplifying breakwater 10.

In this way, after the wave power amplification breakwater 10 is installed, a wave power generation device is installed in the wave power amplification breakwater 10.

Wave power generation generated by using the kinetic energy of the waves concentrated in the concave portion of the wave power amplification breakwater 10 (that is, the first concave portion of the concrete block assembly 100 or the second concave portion of the standing concrete structure 300) The device 20 is installed in the second concave portion of the standing concrete structure 300.

The wave power generation device 20 of this embodiment is a temporary animal-type power generation device that generates power by directly using the vertical vibration of the wave.

This wave power generation device 20 is disposed in the concave inlet 12 of the wave power amplifying breakwater 10 and has a hemispherical floating body 22 and a semi-spherical floating body 22 in which the shape of the embarkation portion faces downward. (12) It comprises a floating body guide portion for guiding so as to be movable in the vertical direction, and a power generation portion for generating electric power by using the vertical movement of the hemispherical floating body 22.

The hemispherical floating body 22 is a floating body in which the shape of a portion to be embarked on the sea level faces downward and forms a hemispherical shape. The hemispherical floating body 22 enables the wave power to be effectively transmitted irrespective of the direction in which the wave is incident, and minimizes the impact of the wave so that it is not easily damaged by the wave.

The floating body guide portion is for guiding the hemispherical floating body 22 so as to be movable in the vertical direction within the concave portion 12. The floating body guide 21 only needs to guide the vertical movement of the hemispherical floating body 22, and thus can be designed in various structures. For example, the floating body guide portion may have a rail structure that guides the hemispherical floating body 22 to linearly move in the vertical direction.

The floating body guide part of the present embodiment is a rotation support 21 whose one end is rotatably coupled to the concave inlet 12 of the wave power amplifying breakwater 10 and the other end is coupled to the hemispherical floating body 22. Rotation supports 21 are provided in a pair to hold the left and right sides of the hemispherical floating body 22 and support them so as to be rotatable in the vertical direction. The rotational support 21 of this structure guides the hemispherical floating body 22 to move in the vertical direction while drawing an arc according to the vertical vibration of the wave.

When the rotation support 21 is completely rotated upward, the hemispherical floating body 22 can be fixed to the wave power generator installation space 12a. If the hemispherical floating body (22) is stored in the wave power generation device installation space (12a) by rotating the rotation support (21) upward, damage to the wave power generation device (20) from a typhoon can be prevented, and in case of failure, it can be easily accessed and repaired. Or can be replaced.

The power generation unit is for generating electric power by using the vertical movement of the hemispherical floating body 22. The power generation unit of this embodiment has one end rotatably coupled to the concave inlet 12 of the wave power amplifying breakwater 10 and the other end rotatably coupled to the hemispherical floating body 22 in the vertical direction of the hemispherical floating body 22 Electric power is generated by using the cylinder member 23 whose length is variable according to the movement.

That is, the power generation unit of this embodiment is a device that generates power through the cylinder member 23 whose length is variable according to the movement of the hemispherical floating body 22.

The cylinder member 23 may be a hydraulic cylinder through which a fluid filled in the cylinder member 23 enters and exits and transmits kinetic energy. A specific operation method of the cylinder member 23 and a power generation method of the power generation unit may be changed according to embodiments.

The wave power generation system using the wave power amplifying breakwater according to an embodiment of the present invention amplifies the wave power by concentrating the wave to the concave portion 12 of the wave power amplification breakwater 10, and uses the amplified wave power to use the wave power generation device 20 ) To enable power generation to take place.

Conventional wave power generation systems generally use only some of the waves incident on the wave power generation device to generate power, and in order to maximize the energy of the incident waves, a method such as increasing the contact area of the floating body to the sea surface. Was used.

However, in the wave power amplifying breakwater 10 according to an embodiment of the present invention, the incident waves are gathered to the concave inlet 12 along the inclined wave guide 13, and the waves collected in the concave inlet overlap each other. It was made to vibrate with a large amplitude.

Since the wave of the concave inlet 12 has a large energy and vibrates with a large amplitude, a large amount of wave energy can be converted into electric power by providing the wave power generation device 20 thereto.

The wave power amplification breakwater 10 of the wave power generation system using the wave power amplification breakwater according to an embodiment of the present invention is different from the breakwater constructed using a tetrapod (TTP), 1-1, 1-2, 2-1, 2-2 Since the concrete blocks (110, 120, 130, 140) are simply stacked to form a concrete column (200), it is very easy to construct.

In addition, 1-1, 1-2, 2-1, 2-2 concrete blocks (110, 120, 130, 140) can be stacked to be offset from side to side and bonded to each other, as well as to be bonded to the underwater ground (1) in the vertical direction, making it a sturdy structure. Since is formed, the construction cost can be significantly reduced compared to the method using a large caisson, and the construction period can also be shortened.

In addition, the wave power generating device 20 is not densely arranged so as to cover all areas where the wave power is incident, but is arranged at regular intervals, so that the number of wave power generating devices 20 does not need to be greatly increased, and the wave power generating device 20 ), the wave is concentrated to the concave portion 12 of the wave power amplifying breakwater 10 installed, so that the wave energy is amplified, so that higher power generation efficiency than the conventional one can be expected.

In addition, the wave power generation device 20 of this embodiment has high structural stability and can be easily operated, and the shape of the landing portion of the hemispherical floating body 22 is a hemispherical shape, so there is a concern about the damage of the wave power generation device 20 according to the direction of incidence of the wave. There is no.

In addition, it is possible to create a hydrophilic space in the upper concrete structure 300 of the wave power amplification breakwater 10 to enjoy leisure activities such as fishing, and to perform various functions by installing additional facilities such as a lighthouse. It can be used as a space, and it can be used as a site to educate on wave power generation and promote eco-friendly energy.
