Description

Water-mounted Solar Power Plant {WATER FLOATING TYPE SOLAR PHOTOVOLTAIC POWER GENERATOR}

The present invention relates to a solar cell module installed in the water, such as lakes, reservoirs, rivers, seas, and more specifically, it is possible to generate electricity by converting solar energy into electrical energy, environmentally friendly, and is configured to float on the water The present invention relates to a water-mounted photovoltaic device that does not use a separate land facility.

In general, electricity generating devices may be classified into thermal power generation using fossil fuels such as petroleum and coal, and solar, nuclear, hydro, tidal, and wind power generation depending on the energy source used.

Among these power generation apparatuses, the power generation apparatus using nuclear power has an advantage of generating electricity at a lower cost than thermal power generation, but installation is limited due to environmental pollution and harmfulness of human body due to radiation. In recent years, facility investments have not been made smoothly due to the disposal of nuclear waste generated after electricity generation.

In addition, in the case of thermal power generation, fossil fuels such as coal and petroleum are used. These fuels not only emit substances polluting the environment when electricity is generated, but also have a high cost of fuel. In addition, in recent years, oil prices have increased due to a decrease in resource reserves. Accordingly, power generation costs have increased, and thus, development of clean energy that does not generate substances polluting the environment is required.

 In addition, in recent years, regulations to suppress the emission of carbon dioxide have been implemented around the world, and development of a new power generation device without carbon dioxide emission is required.

There is no emission of carbon dioxide, and as a power generation device using clean energy, a solar power generation device is typical, and in recent years, the development and installation cost of the technology has become more and more widespread.

Such photovoltaic devices have a difference in power generation capacity depending on the generation area and the amount of sunshine. However, in order to install such a photovoltaic device in a large area, there are many limitations in the purchase of land due to the use of huge land, and there is a problem of costly due to the purchase or compensation of land, and large-scale power generation In order to install the facility, there is a difficulty in drawing cooperation of the surrounding residents.

In addition, the photovoltaic device installed on the land as in the prior art generates a large amount of heat in the process of generating electricity by receiving the sunlight, and a large amount of heat is transmitted from the land on which the photovoltaic device is installed, have. As such, the heat transferred to the photovoltaic device is a cause of deterioration and failure of the solar cell module and a problem of lowering the power generation efficiency of the photovoltaic device.

An object of the present invention is to solve the above-mentioned problems of the prior art, it is possible to solve the large-scale land use problem required for the installation of the photovoltaic device, and thus do not have to purchase land for the installation of the photovoltaic device The construction cost required for initial installation can be lowered, and the heat dissipation naturally prevents the solar cell module's performance degradation and failure, and also improves the power generation efficiency. It is to provide a water-mounted photovoltaic device that can protect.

The water-mounted photovoltaic device according to the present invention for achieving the above object is made transparent to allow sunlight to pass through, and a hollow portion is formed therein, the cover portion having buoyancy, and installed in the hollow portion of the cover portion And a solar cell module coupled to a solar cell to generate electricity by receiving sunlight, wherein the cover part is made of a transparent material to allow sunlight to pass therethrough, and an upper cover having a convex shape to the upper side, and the upper portion. It is coupled to the lower portion of the cover without a gap and has a lower cover having a convex shape to the lower side, at least one of the upper cover or the lower cover is installed to enable the injection or discharge of air by installing a valve or air inlet, It is formed of a flexible material that can be deformed upon injection or discharge.

In addition, the water-mounted photovoltaic device may be connected to other water-mounted photovoltaic devices adjacent to each other made of a plurality. In addition, the upper cover and the lower cover may include upper and lower flanges extending from each outer circumference and coupled to each other. The upper and lower flanges may be formed with at least one connection hole for coupling with another adjacent water-mounted photovoltaic device. In addition, the solar cell module may be made of a flexible type capable of predetermined elastic deformation.

Since the water-mounted photovoltaic device according to the present invention configured as described above does not use a separate land when installing the photovoltaic device, it is possible to reduce land use problems and overall costs therefor, and does not generate carbon dioxide. As a power generation method, CO2 credits can be obtained later, and new profits can be generated by trading CO2 credits thus obtained. In addition, the present invention can quickly dissipate and cool the heat generated in the process of the solar power generation module using the solar power through the water to generate a battery that can prevent performance degradation or failure of the solar power module Can increase the efficiency. In addition, the present invention, since the solar power module is shielded from the outside, it is possible to prevent damage caused by external foreign matters, it may bring durability and life improvement. In addition, the present invention is not only a simple configuration, but also by adjusting the amount of air filled in the inside of the cover to adjust the height of the float, it is possible to minimize the volume by discharging the air during natural disasters such as typhoon, tsunami, flood Therefore, it is possible to effectively store and store the photovoltaic device on land.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

More specifically, the buoyancy body is formed of a cover portion 12 having a buoyancy by forming a hollow portion therein. The cover part 12 is composed of an upper cover 13 and a lower cover 14 coupled to a lower portion of the upper cover 13 to form a hollow part therein.

To this end, the upper cover 13 is formed in a convex shape on the upper side, the lower cover 14 is formed in a convex shape on the lower side. The upper cover 13 and the lower cover 14 have upper and lower flanges 13a and 14a formed at respective outer peripheries, respectively. The upper and lower flanges 13a and 14a are formed to correspond to each other.

The solar cell module 20 is fixedly installed in the hollow part of the cover part 12. In this case, the solar cell module 20 is installed between the hollow part of the cover part 12, that is, the upper cover 13 and the lower cover 14. In addition, the solar cell module 20 is fixed by heat sealing the upper and lower flanges 13a and 14a of the upper cover 13 and the lower cover 14 or by using an adhesive. The solar cell module 20 may be formed of a substrate 22 and a plurality of solar cells 24 fixed to the substrate 22. Preferably, the substrate 22 is made of a flexible material, and thus the solar cell module 20 has a flexible characteristic in which a predetermined elastic deformation is possible.
