{WATER FLOAT FOR FIXING SOLAR POWER PANEL}

The present invention relates to an aquatic solar panel fixed float, and more particularly, to a float type solar panel fixed float, more specifically, a float type float arranged in a matrix, a concave groove and a connecting projection are fastened and fixed by a longitudinal screw connection, And which can easily and quickly assemble and disassemble the solar panel without any additional tools or equipment.

A float is a water buoyant structure that can construct various marine structures such as houses, various barges, water bicycle roads, water stage, water condition power plant, etc., on the water surface by using an object having a specific gravity lower than water or a hollow type body. to be.

Float is a structure to hold lifesaving and expensive fixtures at the waterfront, and structural stability and durability are very important because it is always exposed to seawater including salinity, fresh water environment where ice pressure acts, and typhoon, flood and wave. In addition, it should be possible to combine various sizes and forms in terms of function, to safeguard the facilities and to enable easy maintenance.

Recently, float can be manufactured in various sizes and shapes, and it is extensively used as a structure suitable for the purpose by making it easy to attach and detach various kinds of accessory facilities by using extruded aluminum frame. In addition, the assembly float which can be assembled in various forms and has little effect on the change of the marine environment and has a low effort and cost is actively developed.

On the other hand, with the aim of responding to environmental problems and securing a sustainable energy source, the development using renewable energy has been rapidly spreading. Among them, the PV system has been actively developed from small households to large- It is widely used in real life.

As a result, many new application technologies related to the installation method of solar light and the improvement of operation efficiency have been developed, and recent water-based photovoltaic power generation has attracted domestic and international attention. Water-based photovoltaic power generation is a new concept of photovoltaic power generation that combines existing land photovoltaic technology with water floating technology.

Conventional land photovoltaic power generation is largely divided into the installation of photovoltaic power generation facilities in buildings and the installation of photovoltaic power generation facilities in the land. In case of installing solar power generation facilities in buildings, there are difficulties such as installation area, structural stability, long-term lease, and interference of shade due to high-rise buildings. In case of installing solar power generation facilities on land, A related problem occurs. However, water-state photovoltaic power generation has an alternative that can solve many of these problems.

Photovoltaic facilities installed in buildings are generally roof-top solar facilities. On the rooftop solar facility, when the ambient temperature is 35 ℃ in summer, if the module temperature exceeds 50 ℃, the power generation is rapidly decreased. On the contrary, the water temperature is not higher than 28 ℃ in summer and the module temperature is 55 ℃ The power output is not reduced compared with the land level.

Water-based photovoltaic power generation has been researched and developed in Korea and Japan since 2008, and the research and development is being promoted in 2012. Generally, water-based photovoltaic power generation has a structure in which a solar module is fixed to a float.

Fluid can be classified into frame type and buoyancy integral type. Since the frame type has high structural stability, it can design the module inclination angle to 33 ㅀ, which has the advantage of high utilization rate of power generation, but it is installed in a region where the maximum design external pressure is taken into consideration due to high construction cost. The buoyancy integrated type reduces the vertical and vertical wind load which acts as the maximum design external pressure by lowering the module inclination angle. The electricity utilization rate is 3.0 ~ 3.5% but the construction cost is 15 ~ 20% lower than the frame type.

However, the biggest obstacle to solar photovoltaic power generation is the cost problem, which is 1.5 times that of land photovoltaic. In order to lower the construction cost, the development cost of the water floating structure, which has the largest cost ratio, is required to be reduced remarkably.

Accordingly, the present invention can reduce the manufacturing cost and freight cost of float by fixing a plurality of single floats of the integrated type in the assembled manner to fix the floodlight solar panel, and quickly and easily disassemble and disassemble the float without any separate tools or equipments ≪ RTI ID = 0.0 > a < / RTI > fixed float.

2 is a perspective view of an aquatic solar panel fixed float of the present invention. The float 10 has a closed polyhedron or a hexahedral shape and serves as a buoyant body in the water phase. The float may be used as a support for supporting the solar panel or as a footrest for walking.

The conventional float solar photovoltaic float constituted one set in which the solar panel support and the scaffold were separated. However, the float of the present invention is characterized in that the float of a single body combines one or more floats, It is easy to manufacture and the manufacturing cost can be saved.

That is, according to the present invention, a plurality of floats may be assembled horizontally according to the convenience and situation of the user, and the floats may be formed broadly as a foot plate or a separation distance between the solar panels may be widened. By adjusting the spacing between the solar panels, it facilitates the heat exchange between the water and the panels to help cool the solar panels and prevent the solar panels from being damaged by the flow of the water.

A number of surface protrusions formed on the top of the float increase the frictional force of the float surface, thereby facilitating movement when the user uses the float as a footing plate and sliding the operator while walking by seawater or fresh water at sea, So that the work can be performed quickly and safely. In addition, foreign matter accumulated on the surface of the float can easily escape along with the seawater through the surface protrusions and can be prevented from being easily damaged.

As shown in FIG. 3, the float having a hexahedron-shaped connection assembly portion complementary to each other can be mounted on a transportation container box having a rectangular shape in a normal, upward, downward, leftward, and rightward directions to minimize dead space within a limited space It has an advantage that the container space to be transported can be efficiently utilized.

Especially, the transportation cost, which is included in the value added cost of the product, is an important factor that greatly affects the producers and consumers in the price formation. The present invention has the possibility of exporting as a solar energy related invention which is attracting worldwide attention, It is efficient in that it can reduce the cost of operating overseas freight.

4 is a rear perspective view of the float solar panel fixed float of the present invention. The connection assembly 20 assists the connection of the floats. The connection assembly part has a pair of connection protrusions formed on one side surface of the float and recessed grooves formed on the opposite side of the float, and the pair of the connection parts are formed in the lateral and longitudinal directions of the float. The concave groove 22 and the coupling protrusion 23 are complementary to each other so that they can be mutually merged.

5 is a perspective view showing the connection of the connection assembly and the connection bolt of the fixed float of the water solar panel of the present invention. The connection between the floats can be achieved by inserting the connecting protrusion 23 of the other float connecting assembly into the concave groove of the float connecting assembly part so that the plurality of floats extend upward or laterally. The shape of the float vertically coupled to the upward direction of the float positioned in the horizontal direction has a shape of "ㅗ ", and a plurality of floats coupled in the shape of" ㅗ "

The "floated" float is used as a support for supporting a solar panel by installing a solar panel support on the top of a float that is vertically placed, and a horizontally arranged float can be used as a footing.

The concave groove and the connection projection of the connection assembly portion are formed with a through hole having a through hole or a screw thread, the upper and lower portions of which are open. The through holes are positioned so that when the connecting protrusions are inserted into the concave grooves, the through holes are in contact with each other, and the through holes of the concave grooves penetrate the upper surface and the lower surface of the float. The through hole of the upper surface of the float is formed with the receiving groove 36 so that the head portion of the connecting bolt is recessed.

The connecting bolts 21 are inserted through the vertical holes formed by the concave grooves and the connecting protrusions, and can be tightly coupled to absorb shocks such as waves by corresponding to the threads formed in the holes. When the float is used as a solar panel support, a solar panel support can be used by being coupled to the connection groove 25 of the float.

At this time, a cruciform or straight bolt groove is formed in the upper part of the connection bolt and extended and connected to the connection groove 25 of the float, so that rotation of the connection bolt can be fixed by sliding coupling with one side of the solar panel support. Therefore, the connection bolt can not be rotated until the solar panel is dismantled and the panel support is separated, so that the float and the float part can not be separated.

The solar panel support serves to support the solar panel, and its top is inclined by 10 to 60 degrees. The inclination angle of the upper part of the solar panel support can be made different depending on the altitude of the sun, the azimuth angle, and the inclination angle. The solar panel supports are arranged in a straight line with two solar panel supports having the same angle but different height at the front portion and the rear portion with respect to the connecting groove.

The solar panel support base of the aquatic solar panel fixing float according to the present invention has a rear perspective view and a coupling principle with a float, wherein a connection groove is formed in an upper part of the float so that a solar panel support can be installed. The connection groove has a space portion at a central portion thereof and a sliding portion at both sides of the front portion and the rear portion with respect to the space portion in which the lower surface of the solar panel support can be prepared to slide, The sliding coupling portion is formed in a cross-sectional space shape of a downwardly converging light and has a projecting engaging portion 24 which can be engaged with a concave engaging portion 35 formed on a solar panel support on an upper portion thereof.

That is, the grooves formed at the center of the connection grooves have the same cross-sectional area at the upper and lower portions, and are a space for temporarily accommodating the panel supports to be slidingly coupled. The connection grooves formed at the front and rear portions have a narrower upper portion than the lower portion Thereby preventing the slidingly coupled solar panel support from being easily separated from the float. In addition, the lower end surface of the solar panel support is formed with projections in the form of a concave shape having a shape such as "ellipse" or "ellipse" so as to be engageable with the front and rear float upper connection grooves, And are coupled and fixed in a sliding manner to the side.

And a sliding engagement portion at both the front portion and the rear portion with respect to the space portion and the space portion.

In the float, two connecting bolt holes are formed on the upper surface of the concave groove, and are integrated with the front and rear connecting grooves into which the panel supporting rods are inserted, and are slidably engaged with the lower end surface of the solar panel supporting rods, thereby fixing the connecting bolts. However, since the connecting bolt formed on the float of the foot part where the lower end surface of the solar panel support is not required to be inserted is exposed as it is, the connection bolt can be released by the movement of the wave, . ≪ / RTI >

Therefore, a connecting groove for slidingly connecting the connecting bolt of the portion where the lower end surface of the solar panel support is not coupled is formed and a separate sliding cap (see blue yellow in FIG. 7) is inserted in the vertical direction and the horizontal direction, And a sliding cap (refer to the middle part blue in FIG. 7) which can be combined with the auxiliary direction and fill the space of the connecting groove. With this modification, the float of the foot plate portion which does not support the solar panel can be formed with the double locking effect through the sliding cap after the bolt is coupled, and the space of the connection groove can be filled with the float to prevent the seawater from flooding.

Fig. 8 is a perspective view showing a coupling principle of a solar panel and a solar panel support. A protrusion is formed on the upper part of the solar panel support to connect with the solar panel by sliding connection. Also, at one side of the solar panel support, there is a through hole having a nut formed therein, so that the solar panel is bolted to prevent the solar panel from being easily separated from the solar panel support.

9 is a perspective view showing a panel cable holder of a solar panel support. A panel cable holder 31 is formed at one side of the solar panel support to form a hook having a horizontal through hole and a vertical hole so as to arrange the electric wires connected to the solar panel.
