Abstract

The present invention relates to a buoyant body to provide buoyance to a floating structure operated on the water and, more specifically, to a floating photovoltaic plant operated in a manner which adds or removes air and water to or from a buoyant body group formed with one or more buoyant bodies to adjust the height and the self-weight of a floating structure. In general, a pontoon is a buoyant body for fixing a conventional floating photovoltaic apparatus. However, the pontoon has a problem which becomes waste when being broken by deterioration, overload, external shock, wave, and the like so as to pollute a river or the sea, and causes a situation threating life of animals/plants and fish/shellfish. In particular, the pontoon has breakage risk of being easily lost and an economic problem due to a physically weak coupling part and a light structure which are formed in a process for making a floating structure. To improve such point, load can be adjusted while maintaining physical buoyance such that a buoyant body is not easily lost by wind or wave, and is easily managed by increasing coupling force. Moreover, such method can be applied and operated to various places, such as a fishing or leisure mooring, a floating photovoltaic plant, and the like. According to the present invention, the buoyant body comprises an opened structure to receive water, an air outflow prevention structure, a structure including a partition, and a coupling structure.

Description

[0001] Floating solar power system with hight adjustment pontoons [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water structure capable of changing the height and inclination of a buoyant body by controlling air pressure and water pressure, and a solar power generator using the same.

The buoyant body is a method of regulating the bottom opening structure and the valve. By controlling the buoyancy and weight, it is possible to operate the water structure safely from typhoon or natural disaster, and to track the position of the sun through the control means. There is a feature that enables the operation of a state dimming plant.

Generally, a buoyant structure (pontoon) is used for fishing, marine sports, and anchorage of a ship. The buoyant body is generally a hollow type having hollow inside and a buoyancy type filled with buoyant agent such as styrofoam inside.

These methods require additional processing, such as injecting the left and right sides, and additionally filling the inside with the stolopol, so that the production speed is low, the procedure is complicated, the productivity is low, and the price is relatively high.

Also, in order to fix the structure to be installed on the upper part, a steel structure is frequently used, and the weight is increased again, resulting in a vicious cycle in which a buoyant body is required to be used more.

In addition, the hollow buoyant body has the problem of losing its buoyancy when it is broken, and the insertable buoyant body is a micro-struck pole piece that disturbs the environmental destruction and the ecosystem at the time of breakage, threatens the life of the fish, There is a problem that the health of the user is deteriorated.

As can be understood from the prior art and the types of products currently on sale, the buoyancy body has a high production cost, a small size to be produced, and difficulty in quality control since sealing, watertightness, and quality of contents greatly affect the buoyancy effect .

In addition, since the buoyant body is small in size, the water structure is manufactured by bundling several pieces in order to obtain a sufficient buoyancy. In addition, the number of coupled parts is increased, Are more likely to be damaged due to waves or winds, which increases the likelihood of more administrative costs being incurred.

This is an important issue for the project, where the cost and installation cost of the structure, such as a water solar power plant, is a big variable for plant operation.

10-1575155, in which a ballast tank is used in the registered prior patent, is a vessel in which the ballast tank of a ship is intact, it can not be said that the air pressure of the present invention is controlled, and the water does not have the purpose of weight and airflow.

The present invention has been made to solve the above-mentioned problems,

The unit buoyant body can be injected onto one side, thereby increasing the production speed.

The object of the present invention is to provide a buoyant body which can cope with the weather change and the purpose of use inexpensively.

It is aimed at a buoyant body which is easily watertight and does not flood even when the buoyant body is partially damaged.

It is aimed at a buoyant body with little stranding or breakage due to strong binding force in typhoon or wave.

And aims at realizing high power production efficiency compared to installation cost by changing the inclination or orientation along the movement path of the sun.

The present invention aims to realize the following objects.

The buoyant force of the unit buoyant body can be increased or decreased by using air and water.

The unit buoyancy structure is characterized by the fact that the inside is empty, thereby minimizing the concern of environmental destruction even if it is damaged due to natural disasters such as typhoons or gusts and artificial accidents.

The augmented structure using the unit buoyant body lowers the height of the buoyant body by the information collected from the sensors installed inside and outside the unit buoyant body to prevent overturning due to gust wind or floating due to typhoon, The load is sufficiently dispersed by adjusting the air pressure of the buoyant body connected to the buoyant body.

A water structure composed of a unit buoyancy structure has a feature that it can be manufactured largely because the burden of watertightness and sealing is small.

The unit buoyant body is characterized in that the buoyant force can be made higher than the conventional buoyant body by increasing the air pressure.

The buoyant structure using the buoyant buoyant body is characterized by high buoyancy and low installation cost and applicable to various fields.

According to the present invention, since a simple structure having an empty interior is used, there is an effect of preventing an environment caused by physical buoyancy or the like, such as a squeeze.

According to the present invention, the water structure using the lifting system can withstand more loads by the air pressure, thereby reducing the economic effect.

According to the present invention, a simple structure in which the interior is hollow allows a unit structure to be stacked and stacked, thereby saving space during storage and minimizing the moving means during movement.

According to the present invention, the sensors installed on the water structure detect the flow of water, the state, the wind, the vibration, the collision, and the like, and can monitor the environment.

According to the present invention, the water level control type water structure has the effect of maintaining the safety of the structure or preventing the dead fish from being spun by moving the water surface or downward when typhoon, green tide, or red tide.

According to the present invention, a water structure using an air pressure control type elevating method is effective in effectively operating heavy equipment such as a solar power plant or a wind power plant installed on a watercraft.

According to the present invention, the pneumatic pressure type water structure can move the solar power generation device vertically and horizontally, thereby improving the efficiency of solar power generation.

BEST MODE FOR CARRYING OUT THE INVENTION The most preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

The present invention relates to the implementation and operation of an aquifer power plant using a buoyant body capable of adjusting the height, and is designed to solve problems such as unstable operation due to wind, environmental pollution caused by wind damage, low economic efficiency, etc. will be.

Since the lower portion of the buoyant body according to the present invention is opened, the importance of the airtightness relative to the existing products is relatively low, so that it is economical without precise operation requiring airtightness. However, the lower cover that can be opened and closed can control the load, which can overcome the limitations of existing products that can only be used in areas where there are waves and winds.

In addition, by controlling the height of the buoyant body, it is possible to change the slope of the solar cell installed at the top, and to perform the function of tracking the position of the sun depending on the shape.

Furthermore, the addition of the actuator 350 to the solar cell supporting structure 300 has the advantage that the position of the sun can be automatically tracked without the need for human administration.

Further, by using the protrusions 160 capable of fitting the buoyant bodies, movement can be restricted more strongly, and the binding tape 200 and the U-shaped external fixing part 210 are inserted like a wedge, There is an advantage that a stronger coupling is easier to use.

FIG. 1 is a side view of a water-based photovoltaic power generation apparatus using a buoyant body according to the present invention. FIG. 1 is a perspective view of a slider 370 or a slider 370 provided to vertically move and couple between two buoyant bodies 100 floating on a water surface 105 And the hinge structure is combined.

Solar cell support structure 300 330 The upper part of the actuator 350 is schematically illustrated as floating near the water surface by injecting air into the buoyant body on the right side (rear side) with respect to the buoyant body on the left side (front side) , It is preferable that the connecting portion of the solar cell supporting structure 300 installed at the upper end of the buoyant body is realized so as to correspond to the movement of the buoyant body with the hinge structure.

Further, the variable bridge structure of the solar cell supporting structure 300 installed to change the inclination of the solar cell holder 330 is provided with an actuator 350 and a wedge 360 for fixing after it is fixed.

The detailed description will be made in detail with reference to the attached drawings.

Fig. 2 is a cross-sectional view of one side of the buoyant body of the present invention, which is a representation of a basic model in which no additional parts are used in the buoyant body. When no air is injected, .

In FIG. 2, the unit buoyant body is expressed simply. However, when a plurality of buoyant bodies are connected, a plurality of photovoltaic power generation facilities can be constructed on the upper part. Of course, as the load increases so much that it sinks deeper, the air is injected into the lower part to adjust the height.

When the buoyant body according to the invention shown in FIG. 2 is used, when the instantaneous maximum wind speed is very short such as a gust of wind, Since the weight of the device as well as the water inside the buoyant body must be pushed to the water, it acts like a coefficient of friction that occurs when pushing objects on land. This is why walking in the bath or swimming pool is harder than walking on the land.

Also, it is advantageous for maintenance and operation to allow air to be injected and removed through the valve installed at the bottom.

It is easy to deepen the depth of submersion if it continues to blow in the same direction and wind speed as in the case of typhoons or monsoons. Preferably, however, it is effective to increase the self-load of the buoyant body by providing a water trapping apparatus by providing the openable and closable bottom cover 140 as shown in FIG. This is the reason why large vessels have equilibrium water.

Also, in FIG. 2 or 3, it is difficult to understand the explanation that the buoyant body is stopped or the movement is small in spite of the strong wind, because the unit buoyancy body is explained. However, As an example of a power plant of a size, it should be clear that the method of adding frictional force or load here to more than 10,000 square meters is not a small resistance.

Unlike the buoyant body, which can control the height by adjusting the air pressure, the existing products lead to the flooding of the nearby buoyant body due to some damage, and the neighbor buoyant body Since the propagation of breakage damage can be predicted, the photovoltaic power plant using the conventional buoyant body is structured such that the buoyant body is floated on the surface of the water or is set to a degree that it sinks slightly, so that it is difficult to generate frictional force or repulsive force.

FIG. 3 is a cross-sectional view of a buoyant body according to the present invention, which includes a compartment 115 in which air can stay at the time of breakage through an internal partition wall 110 installed in the buoyant body.

The buoyancy device is configured such that at least one protrusion protruding from the inside to the outside is fitted to the outside of the buoyant body so that they can be fitted to each other. Preferably, the buoyant device has a wedge shape that is not easily released after nipping.

Also, the barrier ribs 110 are not installed in a predetermined space in the lower portion, so that the air introduced through the valves can be smoothly moved.

Also, it is preferable that the valve has a pipe structure connected to each compartment 115, or includes a through hole or a physical moving method in a partition wall having a constant height.

FIG. 4 is a cross-sectional view of one side of the buoyant body lower cover according to the present invention. In the lower part of the buoyant body illustrated in FIG. 2, a closed bottom cover 130 in the form of a plate or an openable bottom cover 130 may be installed. The cover part can change the shape depending on the purpose, but the basic purpose is to operate a stable water-state power plant by controlling load and buoyancy.

5 is a diagram illustrating the manner in which air and water can be moved into the interior of the openable and closable lower cover 140 by using the cover opening and closing part 150. The openable and closable lower cover 140 is automatically opened or closed in accordance with the movement of water, Preferably,

Furthermore, it is more desirable to implement functions such as injecting air using a submersible robot or opening and closing a cover.

Among the conventional products, there is no water-pumped power plant using pontoons or buoyant bodies filled with water, but there exists a patent to stabilize the buoyancy of the buoyant body and build a solar power plant thereon, as if the equilibrium is maintained using water in the boat . However, the results are different from those of the buoyant body of the present invention, in which the flow is freely in the water in the open state, the water does not rot inside, and the air is controlled.

6 is a view illustrating an example of a buoyant body fixing method according to the present invention.

On the outer side of the buoyant body, a groove is formed so as to use a channel or a H-shaped channel or section as a reinforcing agent for fixing, and this groove is a buoyancy structure in which a protruding portion of a channel or a section can be inserted.

A plurality of buoyant bodies are arranged laterally and longitudinally with the fixing reinforcing agent, and the protrusions 115 are fitted, and a wedge is inserted into the separated portions to securely fix the wedges. Also, it is advantageous and advantageous to limit the up-and-down flow of the addition of the fitting structures which enhance the binding of the arrangement.

In the present invention, the bonding method used as a means for fixing the buoyancy members means a method of integrating with a material such as a buoyant body or an adhesive, and it is preferable to use a bonding tape in the form of a long and wide tape.

It is preferable to increase the tensile force of the bonding tape together with the adhesive on the inner side of the bonding tape connecting the buoyant body and to improve the cutting repulsive force by sandwiching or bonding the material which makes it difficult to cut.

The slider or the hinge structure is characterized in that it is possible to change the height by increasing or decreasing the air pressure and the weight of the water inside the buoyant body at one side or more and to realize the variable tilting water state power generation device for changing the angle of the solar cell by this method .

It is also preferable that the buoyancy body group coupled with the rows of the matrices is provided with a control structure for installing the piping in the valves of the buoyant bodies disposed separately or in parallel so that air or water can be simultaneously added or subtracted.

The solar cell coupling unit 390 provided at the upper end of the buoyant body has a hinge structure and is configured to change the slope of the solar cell according to the change in the height of the buoyant bodies.

FIG. 8 illustrates a tiltable variable solar photovoltaic power generation apparatus using the actuator of the present invention. It is preferable that the support structure A 310 and the support structure B 320 are realized by a large circular or square pipe, A structure in which the support structure B can be pulled out by fitting it inside and has a larger inner diameter than the support structure B and the support structure B is separated from the support structure A while the actuator 350 is elongated It is also possible.

The portions of the support structure not shown in detail in the drawing are also configured as a hinge structure in a portion where the inclination is changed.

9 is a diagram illustrating an example of the operation of the actuator when the inclination of the solar photovoltaic structure according to the present invention is changed,

It is possible to use the solar cell supporting structure 300 in parallel with the actuator 350 and the wedge 360 structure and to basically move the solar cell according to the solar ecliption. Thus, the slope and orientation can be tracked.

The actuator is installed in the solar cell supporting structure B 320 to fix the sun light and the solar cell at right angles, and after the operation, the actuator is fixed through the wedge 360 structure formed in the solar cell supporting structure to prevent damage due to wind pressure. do. The wedge structure is mechanically or electrically operated, and it is preferable that the wedge is strongly supported to hold the supporting structure A and the supporting structure B by making a hole in an appropriate portion. The actuator is not limited to the above description but can be installed and operated in various parts according to the method.

[

11 is a side view of the water-state photovoltaic generation apparatus of the present invention,

The method of embodying the solar cell coupling unit 390 for fixing the solar cell to the unit buoyant body is difficult because the conventional products use a method of fixing the buoyant body by the iron structure and fixing the solar cell thereon. The buoyant body of the present invention binds the buoyant body 200 with the protrusions 115 and the buoyant body in a wedge manner to minimize the damage problem of the buoyancy body due to the metal fastening device of existing products can do.
