Structural device for algae generation {A STRUCTURE FOR TIDAL CURRENT POWER}

The present invention relates to a structure device for tidal current generation to enable installation of a water turbine generator to enable tidal current and current generation. More specifically, for constructing and installing a structure capable of installing the aberration generator so that the blades of the aberration generator can rotate according to the algae and the water flow for the algae and the water flow. To this end, a barge with a drilling device for digging up to the rock bottom of the sea bottom or river bottom is fixed to the upper surface of the sea or river, and then the excavation hole is formed in the sea bottom or river bottom, and the hollow casing is inserted into the excavation hole. And by reinforcing the reinforced concrete inside the hollow casing to configure the holding body for mounting the aberration generator, while the guide unit is attached to the aberration generator or gearbox to be fixed.

Algae power is generated by installing a water turbine with propeller on the seabed where the algae flows rapidly and then rotating the water generator by the force of the current. In particular, tidal power generation is an energy source that can be developed at any time regardless of climate change or season and is the only renewable energy source that can predict the amount of renewable energy. However, due to the complex technology of converting tidal energy, designing and constructing a structure, and applying and operating a power generation system, research has only recently started in advanced countries such as the US, Germany and Norway. South Korea also succeeded in installing the core structure of the world's largest test algae power plant in Uldulm, Jeonnam. The structure of the installed algae power plant consists of a huge structure weighing more than 1,000 tons, including the height of the upper house, reaching a height of 48m.

On the other hand, in the case of using algae, if the air density in the standard state (20 ℃, 1 atm, 75% relative humidity) is about 1.2, the density of water is about 830 times greater than the air density. Propellers have the advantage of being smaller in size. However, when using wind, the wind speed is usually around 10-20m / sec, while the speed of birds is about 2-5m / sec in Korea.

In addition, in the case of using algae as a rule, the width of the blade is smaller than the propeller of the wind is configured to take the form. There are various reasons, but there was a difficulty in constructing the structure of the blade installed in the water, and in order to install such a large blade, the structure installed in the water also has to be enlarged. There was no.

Moreover, in order to install such a large structure, it is necessary to install a foundation structure on the bottom of the sea or to form a large foundation structure made on the ground by dropping it on the bottom of the sea. There was a high concern that could adversely affect the marine environment ecosystem due to marine pollution.

On the other hand, if the tidal blade is enlarged, it will be possible to secure a technology that can rotate the generator quickly through the governing gear box that converts low-speed blade rotation into a high speed by using a gearbox, even if the tidal velocity is low. There is an advantage that can be obtained.

Therefore, it was necessary to develop a structure for tidal current generation that can install a large size blade for algae while significantly lowering the cost of the structure.

In other words, if the depth from the water surface to the bottom of the sea is 40m and the difference between tidal currents is 6m, the algae can reach 34m and the braid length on one side of the propeller can be 15 meters or more. Will be.

In particular, the blade can be enlarged, so that the contact area of the water flow can be greatly increased, thereby obtaining the effect of ensuring a predetermined power generation at all times even through the rotational speed of the slow blade.

In order to secure such technology, the present invention has been developed for the structure device and the structure installation method through the present patent patent 10-2010-0053975 (patent name: algae and water current generator structure device and installation method) and patent 10-2011-0074181 (patent name : Barge device for installation of algae power generation structure).

This effect can be equally applied to rivers or rivers in which water flow rates are generally formed quickly, and it can be understood as a technology that can solve a problem of difficulty in installing a structure in a region where the water flow speed is fast and deep.

10-2010-0053975 (Patent Name: Algae and Water Flow Structure Structure and Installation Method) 10-2006-0015470 (Patent name: Aberration structure for tidal power plant) 10-2008-0064876 (Patent name: Direction change device for pile fixed current generation) 10-2011-0074181 (Patent name: Barge device for installation of current generation structure) 10-2005-0017964 (Patent name: Algae Generator)

The present invention forms an excavation hole by using a barge and a drilling machine to rock bed on the bottom of the river or the bottom of the river where the flow of water is formed, and then install the reinforced concrete in the hollow casing to support the aberration generator or the gearbox. It is intended to develop a structure device for tidal current generation that can install aberration generator for power generation through low cost and simple method by installing to be fixed to the main body.

In addition, in order to be able to generate power even by slow-speed tidal flow, the blade length and surface area are enlarged so that even if the rotation diameter exceeds 50m or reaches 100m or larger, a structure for tidal current generation capable of accommodating them is provided. The aim is to develop as much technology as possible.

In addition, the vertical rotation shaft supported by the support body to supply the rotational force of the blade to the governor gear box and the generator installed on the deck configured on the top of the support body to supply the technology to install the aberration generator on the sea surface The purpose is.

In addition, the purpose of the present invention is to provide a technology capable of constructing a large capacity algae power generation complex while preserving the marine environment by preventing marine pollution caused by grouting materials in the process of constructing the algae and water current generating structure.

In the algae power generation structure device is installed a water wheel generator or gearbox for tidal current and current generation,

An excavation hole formed by digging to a predetermined diameter size to a rock line below the sea bottom;

A support body inserted into the excavation hole and installed vertically;

A guide portion configured to be coupled to the aberration generator or the gearbox or the bearing housing to enable vertical movement along the support body;

It is characterized by consisting of a fixing device coupled to the guide portion.

The algae power generation structure device according to the present invention is to simplify and simplify the installation structure and process of the algae power generation structure and as a result economical installation. Without installing a separate foundation base on the bottom of the seabed, the hollow casing lowered to the bottom of the seabed using the drill on the barge fixed to the top of the sea level and the inside of the excavated hole and the hollow casing secured by drilling excavation to the bottom rock bed line It has the effect of completing the standard algae power generation structure installation process that can be installed the support body made of reinforced concrete formed.

In addition, the completion of these standards-specific processes allows low-cost and small- and medium-sized tidal current and water current generators to be constructed at low cost, so that tidal power can be easily and cheaply located anywhere on the coast of the island. It is possible to supply power generation to various types of marine power demands such as farming, raising farms, and fishing villages, and to install water turbine generators in large rivers or rivers where the flow of water is maintained at all times. It has the effect of solving the technical problem of the structure installation.

In particular, as described above, it is possible to install and operate a large-sized algae blade, which greatly expands the contact area of algae and water streams, thereby ensuring sufficient blade rotational force even at a slow algae speed of less than 2 meters per second. It is possible to maintain the rotation speed of a similar blade even if the direction of the tide changes, which is one of the components of tide generation, and the speed at which the number of revolutions transmitted to the generator can be generated through the governing gear box that converts the slow rotation speed of the blade to a high speed. As a result, it is possible to increase the power generation to a certain amount of time, thereby achieving a certain amount of power in a planned manner.

In addition, the structure was standardized and standardized to be collectively installed on the seabed, the sea, and the rivers, thereby increasing the size of the algae generation.

The present invention will now be described in detail with reference to the accompanying drawings.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view representing a form in which a hollow casing 69 is inserted while forming an excavation hole 76 by using a drilling machine 72 mounted on a barge 74. In order to determine the position of the excavation hole 76 for inserting and installing the first hollow casing 69, the barge 74 can be fixed at four positions of the barge so that the barge 74 can be fixed without being shaken even in the flow of rapid current or the flow of water in the river. The installed leg part 71 is lowered to the bottom of the sea bottom 6 or the river bottom, and the entire barge 74 is lifted and fixed to the top of the sea level 5, and then the center of the barge 74 is increased due to the height to the sea level 5. The anchor 65 was lowered in each of the four directions so as not to shake, and was fixed to the barge 74 by the chain 64.

Of course, in the case of rivers or rivers, a temporary working table (not shown) may be installed in place of the barge 74, and a drilling machine 72 may be installed on the upper part thereof, and in this case, the temporary working table may be in the range of the barge 74. Should be included together.

When the position of the barge 74 is fixed by the leg portion 71 is installed by lowering the hollow casing 69 to the sea bottom 6 by using the drilling device 72. At this time, the hollow casing 69 is generally used in the size of the nominal diameter 150A ~ 350A, and if necessary, can be equipped with a diameter of 1,000mm or more, and 6m length is the length of one pipe in accordance with the standard through welding work It is installed while connecting.

The inner and outer surfaces of the hollow casing 69 were coated with zinc to prevent corrosion by salt components contained in seawater. Of course, a separate anticorrosion coating may also be implemented.

The drilling bit 77 is coupled to the connection rod 75 using the drilling machine 72 to be pressed into the hollow casing 69 which is already pressed by the bottom of the seabed 6 to proceed with the excavation work. When the excavation hole 76 having a depth of 5 to 15 m is generally formed, when the hollow casing 69 is pressed by using the load of the drill 72, the hollow casing 69 is partially inserted into the excavation hole 76. Will be done. At this time, the drilling device 72 and the hollow casing 69 are taken to be inserted in the vertical direction using a vertical level meter (not shown).

When the excavation to the rock line is completed and the excavation hole 76 is completed, the rebar bundle 66 is inserted into the hollow casing 69 on the barge 74 and the bottom of the rebar bundle 66 is installed in the excavation hole. To reach bottom 78.

Of course, instead of the reinforcing bundle 66, it is possible to use a variety of structures, such as a file connecting the H beam or flat iron of the size that can fit inside the hollow casing 69, all of which will be referred to collectively as the reinforcing bundle (66).

Inside the hollow casing 69, the grouting material that can be made of concrete such as ready-mixed concrete can be installed by inserting the tremi pipe together with the reinforcing bundle 69 to be filled from the bottom of the excavation ball 78. The tremi pipe was constructed using steel pipe pipe to secure the strength of the high density polyethylene (PE) pipe or reinforced concrete, and the concrete solution was injected through the tremi pipe to fill and cure the inside of the hollow casing (69).

In order to allow the injected grouting material to cure and cure in a short time, the hardening cement or quickening agent may be mixed and poured into the grouting material.

In addition, around the hollow casing 69 of the sea bottom 6, a round or square formwork or well is mounted down and a concrete floor is formed at a constant height to support the lower part of the hollow casing 69 more firmly. I did it.

When the grouting 79 is completed inside the hollow casing 69, the columnar support body 70 is completed. The completed support body 70 may be applied in various forms, such as two-type, four-type, and six-type molds, depending on the size and installation form of the aberration generator 1.

Of course, the form constituting the support body 70 is installed in the form of standing up by inserting a steel structure such as "H" beam in the bored state from the excavation hole 76 to the sea bottom 6 or by performing grouting or the sea bottom ( After installing the hollow casing (69) only up to a certain height from 6) after the upper and middle portion is equipped with a support bracket (9) in which the aberration generator (1) is installed may be installed in the form of steel structures such as "H" beam.

One side surface of the support body 70 was configured with a rail portion 60 formed in a plate shape in the vertical direction. The rail unit 60 is configured to be integrally coupled with the support body 70 and its shape is installed in a direction perpendicular to the outer periphery of the support body 70 or in a horizontal direction with the outer periphery of the support body 70. . Of course, the cross section of the rail unit 60 may be rectangular or manufactured in various forms in consideration of the coupling relationship of the guide unit 40.

Aberration generator (1) or gearbox (80) consists of a support bracket (9) in each of the support body (70) and rail portion (60) of the lowest position where the aberration generator (1) or gearbox (80) is fixed. Was supported so as not to fall by the load anymore, and the shock absorber is configured to reduce the fall by configuring the shock absorber 25 on the top of the support bracket (9). The shock absorber 25 may be understood as an elastic rubber or a spring and may be operated by being coupled to the aberration generator 1 or the gearbox 80.

Depth of installation structure of the support bracket (9) is difficult to implement the exact design value in advance during the hollow casing (69) insertion installation process, so that it can be installed by bolt-combining the compensation plate 42 having the planned thickness and strength for height correction Equilibrium is achieved when the aberration generator 1 or the gearbox 80 is installed. Of course, the cover plate 42 is not limited to being installed only in the upper support bracket 9, it may be installed in the aberration generator (1) or gear box (80) lower.

On the other hand, the rail casing 60 and the support bracket 9 are formed in the hollow casing 69 constituting the support body 70 as described above, so that the weight casing and the driving load are added to the hollow casing 69 so that the hollow casing ( 69) In order to prevent structural damage caused by reinforcement of reinforced concrete and peeled by being placed inside, a plurality of longitudinal roots 47 having a “T” shape in the longitudinal direction are arranged on the inner circumferential surface of the hollow casing 69. The structural strength of the hollow casing 69 can be strengthened without disturbing the input of the reinforcing bar bundle 66.

In addition, the aberration generator (1) or the gear while covering the support body (70) while functioning to slide up and down through the operation of the lifting device, such as the load of the aberration generator (1) or gearbox 80 and the winding machine (62) When the details of the box 80 or the bearing housing 50 ("aberration generator 1 or gearbox 80 or bearing housing 50" together in the specification and claims) are designated as a driving device. In addition, a fixed bracket configured to be combined with a horizontal blade 18, a gear box 80, a horizontal shaft bearing (17 and a bearing housing 50 also referred to as a drive device) of the horizontal shaft turbine of the third embodiment to be described later ( The guide part 40 in which 7) was formed was comprised.

Of course, the rail unit 60 and the guide unit 40 formed in the support body 70 may be driven up and down by using a rack pinion gear (not shown).

The guide portion 40 may be formed so as to be able to slide on the rail body 60 formed on one side of the support body 70 itself or the support body 70 by combining a conventional steel structure. As in 2010-0053975 (patent name: current and current generation structure device and installation method), both sides of the rail unit 60 having rollers around the body or on one side of the support body 70 having a cylindrical or square shape It may be configured to allow the sliding drive.

In addition, the guide unit 40 is configured with a fixing device 30.

Fixing device 30 is typically to use an incompressible pressure fluid, such as hydraulic or hydraulic pressure, it is to be understood that the function of the general hydraulic brake. Therefore, although the hydraulic pump and the like for the formation of the pressure fluid in the specification and drawings are not shown and omitted, it should not be understood as an incomplete configuration.

That is, the fixing device 30 is a brake shoe 33 to which the forward and backward function is added by the hydraulic pressure supplied to the hydraulic cylinder 32 to the brake block 31 formed to move around the rail unit 60. Sliding along the rail unit 60 and supplying a pressure fluid, such as hydraulic or hydraulic pressure at the planned position through the high pressure hose 34 between the brake shoe 33 and the rail unit 60 A strong pressing force is formed in the support body 40 or the rail unit 60 so that the guide portion 40 can be firmly fixed.

Of course, the fixing device 30 constitutes a cylindrical guide 41 which is slidable around the support body 70 and penetrates the cylindrical guide 41 so that the brake shoe 33 can contact the support body 70 outer circumferential surface. You can also install and operate it. It will be understood that the cylindrical guide 41 also belongs to the scope of the guide portion 40 in a broad sense.

In addition to the fixing device 30 is a fixed device through a variety of methods, such as to maintain the firmness of the fixed fixed state by forcibly tensioning the fixed pin using a hydraulic cylinder in the method of combining the container and the container when loading the container It is obvious that (30) can achieve the purpose to be obtained, and these various methods will eventually be understood as a category of the present invention.

In addition, the guide portion 40 is configured with a fixed bracket (7) to fix the bearing housing (50) for supporting the aberration generator (1) or gearbox (80), or vertical rotary shaft (20).

When the fixing bracket 7 is coupled to the drive unit 40, the fixing bracket 7 engages the fixing bolt 12 or the bolt nut coupling using the female threaded portion 11 or the flange which is already processed at the predetermined position. To be implemented.

Of course, the fixing device 30 is installed directly on the body of the aberration generator (1) fuselage or gear box 80 without installing the guide portion 40 to fix these devices to the rail portion 60 or the support body (70) You can also

The guide part 40 has the rail part 60 of the support body 70 immersed in sea water for a long time, and the corrosion caused by the gap closure of the sliding drive part due to the growth and growth of seabed habitats such as algae, mussels and oysters. Various methods and devices for removing them need to be developed in order to eliminate them, but blades (not shown) for removing engraftment and corrosion products are installed at the top and the bottom of the guide, respectively, so that these organisms are naturally removed during vertical operation. You can make sure that there are no obstacles.

Meanwhile, the platform 61 is formed on the support body 70 to install the winding machine 62 to connect the chain or wire rope 63 to the aberration generator 1, and then to maintain the winding machine 62 for maintenance. ), The aberration generator (1) was allowed to be lifted above the sea level (5). To this end, the lifting ring 67 was installed at the top of the aberration generator 1.

In particular, the bottom top of the platform 61 is a grating structure or installed as a perforated plate, even if the seawater rises up to the platform 61 due to a storm or the like, drainage is immediately performed, as well as the platform 61 from the impact of the seawater rising from the lower side. ) So that no breakage or deformation occurs.

In addition, since the platform 61 is positioned above the sea level 5 by the support body 70, the wind power generation tower 29 is installed and the wind power generator 28 is installed to support the auxiliary power and emergency power of the tidal current power generation system. It can be used as. Of course, various lightings including warning lights were installed to enhance the convenience of the lighthouse's functions, location markers and night conservation activities.

In addition, in the process of lifting the aberration generator 1 or the gearbox 80 on the sea level 5 of the support body 70, the blade 3 which is lifted to the top of the sea level 5 is separated and mounted. It can be configured a fixed ring (45). The fixing ring 45 is formed after the maintenance maintenance work of the aberration generator (1) or the gearbox (80) by forming a protruding ring and chain that can secure the extension (2) or wing plate of the blade (3). The blade 3 was fixed to the support body 70 during the period so that it could be temporarily stored.

In addition, the support body 70 has a streamlined tip portion 55 installed in the vertical direction in the forward and reverse directions of the birds, respectively, so that the resistance of the support body due to the flow of the birds can be minimized.

In addition, the support body 70 is installed in each of the submersible camera 35 so that it is possible to check the operating state of the aberration generator (1) or the gear box 80, and a hearing sensor (36) is installed to operate the normal aberration generator (1). After recording and analyzing the driving noise in advance, the alarm can sound when an abnormal noise occurs to help maintenance activities.

Of course, the aberration generator (1) may be made of the generator body itself, such as patent 10-2011-0064364 (patent name: algae generator) governing gear box function to increase the rotational speed of the blade (3) therein ( 4) and the generator 15 may be operated as a closed casing (not shown) in which the internal air pressure is automatically adjusted in a state in which both the generator and the generator 15 are embedded, and in the present embodiment, these may be collectively understood as the aberration generator 1.

The aberration generator 1 is connected to the blade (3) which rotates by the tidal current rotates. When the aberration generator 1 is not firmly fixed to the support body 70, severe vibration may occur while the blade 3 rotates, and the rotation speed of the blade 3 is high or the vibration persists. It may appear as a big obstacle in the operation of the water turbine generator (1).

Therefore, the brake shoe of the fixing device 30 is mounted on the support body 70 itself or the rail portion 60 formed on the support body 70 by using the fixing device 30 configured at the lower end of the guide part 40. 33 is strongly compressed according to the operation of the hydraulic cylinder 32 so that the aberration generator 1 fixed to the fixed bracket 7 can be firmly fixed to the support body 70 so that the blade 3 can be secured. The vibration of the aberration generator 1 is prevented from occurring even during the rotation of the.

[Example 2]

It is sectional drawing which expressed the apparatus structure which generate | occur | produces power by transmitting rotational force to the governing gearbox 4 and the generator 15 which were installed in the platform 61 comprised in the upper part.

A bevel gear in which a horizontal blade 18, which is a horizontal shaft turbine, is built in the gearbox 80 through a horizontal rotating shaft 19 in a tidal current generator connected to a horizontal horizontal turbine (Transverse Horizontal Axis Water Turbine), which will be described later. By converting to a vertical rotation by using to transfer the rotational force to the vertical rotation shaft 20 may be understood as the same technical content.

Gear box 80 is seated on the support bracket (9) installed on the support body 70 is fixed to the guide portion 40 by the fixing bracket (7). In addition, the brake shoe 33 of the fixing device 30 is hydraulically applied to the support body 40 by the fixing device 30 formed in the guide portion 40 or the rail portion 60 formed in the support body 70. By virtue of pressing the cylinder 32 strongly, the aberration generator 1 fixed to the fixing bracket 7 can be firmly fixed to the support body 70 so that the gear 3 can rotate even when the blade 3 is rotated. The vibration of the box 80 and the vertical rotation shaft 20 was not generated.

In addition, when the vertical rotation shaft 20 is rotated between two struts 70 in the water of 20 ~ 30m depth, severe shaking may occur when operating without intermediate support, so that the operation of the device may occur. do. Accordingly, the bearing housings 50 are installed at appropriate intervals of 5 to 6 meters around the vertical rotation shaft 20 or at the thickness of the vertical rotation shaft 20, and the bearing housings 50 are respectively fixed in the direction of the support body 70. By mounting the device 30 to be fixed to the rail body 60 constituted in the support body 70 itself or the support body 70, the shaking phenomenon of the vertical rotation shaft 20 at the center of the support body 70 or Rotational force can be transmitted without shaking.

Of course, the bearing housing 50 is a device configured to not interfere with the rotation of the vertical rotation shaft 20 while operating the fixing device 30 takes the form of a general shaft bearing housing, and the rotation shaft 26 penetrates. The top and bottom of each of the shaft rod device (21) is installed so that the grease, such as grease filled for the oiling of the shaft bearings do not leak out, it can take the form of applying the lubrication-free bearing device as it operates in the water.

In addition, the connection between the vertical axis of rotation 20 and the axis of rotation 26 is to be fastened using a coupling coupling ring 51 which is generally applied to the connection of the rotation shaft.

In addition, the clutch 23 is provided on the vertical rotation shaft 20 near the sea surface 5. The clutch 23 blocks the rotational force transmitted through the vertical rotation shaft 20 during the maintenance of the governing gear box 4 so as to increase convenience for maintenance of the governing gear box 4.
