BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a buoy for installing a solar photovoltaic device installed to float on a water surface of a reservoir or the like using buoyancy.

Increasing industrial societies, increasing population, and the use of many electrical and mechanical devices that require electricity require more and more energy. The most widely used energy sources are fossil energy sources such as coal and petroleum natural gas, and nuclear power generation, which are low in electricity generation cost. These fossil fuel sources are gradually being exhausted due to limited fossil fuel stores. It is important to develop alternative energy sources because it has a great impact on global warming because it emits various kinds of pollution including carbon dioxide. The nuclear power generation, which is regarded as an alternative of fossil fuels, As a result, we are looking for alternative energy sources.

On the other hand, unlike fossil energy sources such as coal and petroleum natural gas, solar heat is supplied almost indefinitely at the same time as clean energy without pollution, and it has long been possible to use such solar energy as an energy source for industrial use, heating or automobile And commercialization is being carried out along with steady research.

Currently, solar energy collectors and photovoltaic modules are used as alternative energy sources.

Plate type solar collector and system is a renewable energy system that obtains hot water and heating energy by directly exchanging heat with heat medium by using solar heat energy. It is a renewable energy system widely used because it has high efficiency and high initial investment cost.

Meanwhile, the photovoltaic module and system is a device that generates electric energy by absorbing the light energy of sunlight without environmental pollution and converting it into electric energy by only one installation without needing separate maintenance.

Such a solar device converts light energy, especially solar energy, into electrical energy. The electrical energy generated by the photovoltaic generation is a form of renewable electrical energy that can be used for exactly the same purpose as the electricity generated by the battery or the electricity generated by the established power grid. One type of photovoltaic device is known as a solar module or is referred to as a solar module.

These modules include one or more conventional and preferably multiple solar cells or solar cells located between a substrate sheet such as a clear glass or transparent polymer material and a backing sheet such as a polymeric material, a metal sheet or another glass sheet . The solar cell can be made of a silicon wafer or other suitable semiconductor material or it can be a thin film cell typically deposited on a substrate or backing sheet in a variety of processes and methods known to those skilled in the art of photovoltaic device manufacture . One type of more conventional type of photovoltaic module includes a plurality of individual solar cells made of silicon wafers. Such solar cells are typically made of either single crystal or polycrystalline wafers and typically these multiple individual cells are electrically linked to the desired arrangement to achieve a module having a desired electrical output upon exposure to the sun.

Those skilled in the art of PV module manufacturing are constantly striving to improve the efficiency and durability of such modules and are continually striving to reduce the manufacturing cost of PV modules. Because PV modules need to be essentially exposed to the sun, they are essentially present on an exterior structure such as a building wall or roof to be exposed to the sun, or they may be integrated into a building, Located. The solar modules thus form part of the appearance of the building or other structure in which they are mounted or form part. As a result, solar modules need to be esthetically appealing. Although there has been progress in reducing the manufacturing cost of PV modules and increasing the efficiency of PV modules, purchasing and installing PV modules generally involves significant capital investment.

However, since the amount of solar energy received per unit area of solar power generation is small, a large-scale installation area is required to produce a large amount of energy, and the manufacturing cost of the solar cell device is very expensive. And the use of such electricity is limited to the extent that small-scale electricity is supplemented at home.

In order to obtain such a large power, a problem of expensive land value due to the requirement of a large installation site has recently been considered, and recently, a plan to install a solar power generation device on a shared water surface of a lake or sea is considered.

1 shows a structure in which a base 3 in the form of a barge floating on a water surface 1 of a lake 5 by a plurality of subsections 2 is installed and a solar panel module 4 is installed on the base 3 And the installation of the photovoltaic power generation device on the water surface by using the bell-mouth is recognized as being economically feasible. Recently, installation of the photovoltaic power generation device has been progressing actively.

The method of installing the photovoltaic power generation apparatus using the lake surface 1 described above usually uses the shared water surface owned by the government or the local government, so that expensive land is not required, When the module (4) is installed, the sunlight is prevented from reaching the lower part thereof, and it is impossible to utilize for the cultivation of crops and the like, thereby causing restriction of the land use. However, the installation method using a common water surface such as a lake or a sea has greatly increased interest in recent years because it can reduce the production cost of the solar power by reducing the cultivation area or the expensive land price.

However, in order to install on the water surface using the buoy (2), it is necessary to fix and install the module structure for solar power generation on the buoy (2) floating on the water.

Korean Patent No. 10-0887723 proposes a fixed structure for use in a solar collecting panel. This prior patented invention is based on the idea that the sunlight collecting panel 10 is fixed in the water as shown in FIGS. 2 and 3 And a fixing groove 19 to be assembled with the fixing bolt 21 of the fixing band 20 for fixing the fitting 30 is formed on the lower side of the bending plate 16, And a supporting bar 14 for fixing the solar collecting panel 10. The connecting bar 15 is connected to the bending plate 16 on the upper side of the bending plate 16, And a fixing bar 17 that can support the water and the water can be mounted on the water of the reservoir and the lake.

However, the above-mentioned prior patent invention has a complicated fastening structure as shown in Fig. 3 for fixing the negative hole 30 having a weak hollow strength to the structures 11, 12, 14, 15 forming the frame, It is not only low in productivity but also requires a large number of parts and a large increase in the load to be supported by the bulb 30, so that it is necessary to use a bulb having more or more buoyancy, thereby increasing the manufacturing cost and lowering the economical efficiency, .

In the meantime, the conventional buoy concept is that a simple cylindrical body is weak in strength to support a steel structure having a heavy weight, and a worker has to work while moving along a passage in order to perform maintenance of a power generation facility. And there is a risk that there is a risk due to damage or the like.
