Floating structure for floating solar power plant {FLOATING ASSEMBLY FOR WATER FLOATING SOLAR POWER PLANT}

The present invention relates to a floating structure for water solar equipment.

In general, solar panels manufactured for the purpose of solar power generation are installed through a support in various places where a certain area can be secured, such as on land or on the water, or on the roof or roof of a building. Due to the area-intensive nature of these solar panels, they are mainly installed on inexpensive forest or farmland, which causes a problem of damaging the forest and landscape.As an alternative to this, recently, solar panels are installed on the water using idle water surface. A plan is being introduced.

The method of installing a solar panel on the water is that it is possible to effectively use the land and to prevent the generation of algae through the blocking of sunlight by forming a shade on the water surface due to the shadow of the solar panel without damaging the natural landscape or environment. It has been in the spotlight recently because it has a side effect.

In order to install such a solar panel on the water, a floating support for installation on the water is required.In the conventional floating support for installation on the water, a steel frame is connected to a plurality of buoyancy bodies used in a floating pier or a mooring facility of a ship, and then again on the steel frame. It is completed through the structure of installing solar panels such as solar panels.

However, the conventional floating support for water installation as described above uses a separate buoyant body with strong buoyancy so that the steel frame can float on the water, and these buoyancy bodies are generally plastic or styrofoam (EPS) in direct contact with the water surface. ) Made of material. According to a survey by the Korea Institute of Ocean Science and Technology, plastic buoyancy bodies are reported to be denatured and eventually damaged by UV rays and temperature changes over time, and styrofoam buoyancy bodies are also reported to be microscopically separated from the buoyancy body over time. The problem of particles polluting the underwater environment has been reported to be serious.

As such, the plastic or styrofoam buoyant body has a structural problem that can be easily damaged even by a small impact such as waves or tide because it has low durability and is in point contact with water. Accordingly, the underwater environment is polluted and the cost increases due to the replacement of the buoyancy body, and in severe cases, the entire floating support loses its balance and is overturned, which may cause a serious problem that damages the expensive solar panel.

In order to compensate for the shortcomings of the conventional plastic or styrofoam buoyancy body, a surface-contact type floating structure manufactured by forming a frame of a floating structure using lightweight metal such as aluminum and filling the floating material therein It is presented in Patent Document 1 (Korean Patent Registration No. 10-1843354, March 23, 2018).

The exterior frame 10 may be provided as a structure in which the floating body 20 is accommodated therein and a gap 12 communicating with the interior and exterior is formed. The external frame 10 may be made of a lightweight metal such as aluminum, and may be made of a material having a predetermined or higher rigidity. In addition, the exterior frame 10 may be provided as a bar-type structure that extends long in one direction. Accordingly, the external frame 10 may be suspended on the water surface by a so-called surface contact method. Here, the term "surface contact" is a shape formed to extend in one direction so that one floating body 20 is vertically overlapped with the plurality of solar panels 4 and can be used to mean that the solar panel 4 is suspended. As an example, it may mean a state in which one floating body 20 is disposed so as to overlap in a vertical direction with respect to all of the solar panels 4 constituting one row and is suspended on the water surface.

In this case, a gap 12 may be formed at a corner portion of the sidewall of the exterior frame 10, and the inside and the outside may be communicated through the gap 12. Accordingly, while the floating structure 1 for an aquatic photovoltaic facility is launched, external water penetrates into the interior of the exterior frame 10 through the gap 12, so that the floating body 20 penetrates at least It can float while remaining partially locked. Water penetrating into the exterior frame 10 may act as ballast water within the exterior frame 10.

The floating body 20 is made of a material floating in water, may be made of, for example, polyethylene form, and may be provided in a form that is foamed inside the exterior frame 10. Accordingly, the floating body 20 may be floated while being in surface contact with water while the floating structure 1 for an aquatic solar facility is launched.

The external frame 10 may include an upper structure 110, a lower structure 120, and a side structure 130.
