A barge (BARGE) which is arranged in a plurality of grids in a water phase so as to improve power generation efficiency; Mooring lines and weights provided on one side of the pants so as to prevent the pants from being arbitrarily injured; A plurality of support frames of a predetermined length, which are vertically coupled to the upper surface of the pants and locked at the bottom of the bottom and protruding above the surface of the pants; It is coupled to the outer circumferential surface of the inclined frame that is inclined at a predetermined angle along the lateral direction on the upper end of the support frame, a photovoltaic device that converts and stores light energy irradiated from the sun into electrical energy; It relates to the construction structure of a floating solar power device using bottom pants.

As a form of power generation using clean energy, various types of power generation have been developed that generate electricity using the infinite natural energy that can be obtained from the marine environment through repeated power generation, and at the same time, the range of use is increasing. Indeed, looking at an example of power generation using an energy source that can be obtained from the ocean, various types of power generation are used to generate power by using solar, tidal current, temperature difference, wave power, wind power, and tidal difference.

All of these types of power generation have advantages in that they use clean energy that is independent of pollution, but tidal power generation is difficult to apply universally due to limited location conditions, and tidal flats with heavy construction cost burden. There is a problem that has a huge influence on the environment of a devastated area and a vast area, and wave power generation and seawater temperature difference generation are also difficult to be universally applied due to limited location conditions.

In the marine environment, algae power is emerging as an alternative in that it can continuously develop regardless of weather changes and use clean energy sources without pollution. Compared to this, it is possible to use a wide range, and it has become a great concern in terms of actively using the kinetic energy of algae, but there is a problem in that the structure is complicated and the limitations on power generation capacity follow.

In order to solve these problems, various clean energy developments have been conducted in various ways, and among them, various studies have been conducted to improve the practicality and efficiency of power generation devices using solar heat or solar cells.

Since the photovoltaic device generates electricity using sunlight, the amount of power generated may increase as the amount of incident light increases, and for this purpose, various systems, such as photodiodes, are used for the solar cell to track sunlight. A method of using, a method of using GPS location information, a method of rotating a fixed value using azimuth information of the sun, and the like. However, when the photovoltaic device is installed on the ground, a large frame in which solar cells are installed must be installed, and additional devices must be mounted to rotate the frame or rotate each solar cell for solar tracking. Therefore, the installation cost can be very high.

To solve this problem, in recent years, floating solar power generation devices that can be used in places where it is easy to secure sunshine, such as the sea, rivers, lakes, or reservoirs, have been distributed in various forms, for example, application number 10- 2011-0070074 "Suspended floating body and floating solar power generation system having the same".

The photovoltaic power generation system includes a sealed tube having an enclosed inner space and a cover tube surrounding the sealed tube, the sealed tube is a metal material, the cover tube includes concrete, and is provided on an outer surface of the cover tube. A plurality of coupling members to which other parts are coupled and a plurality of coupling members are provided, the coupling members are arranged to form a row, and the rows of coupling members and rows of coupling members are 90 ° out of phase with respect to the central axis of the cover tube Will have

However, the above photovoltaic power generation system forms a concrete layer by applying concrete while the floating body encloses the metal sealed pipe and the sealed pipe, and contaminants may be discharged when the concrete is placed in water for a long time. Cracks may occur in the concrete, and there is no way to reduce buoyancy when partially replaced, so it is difficult to move underwater, so if a repair or floating is needed, move the module support structure and solar cell module to the ground or move the marine crane. Since it has to be lifted and replaced, it is expected that problems such as excessive maintenance costs, complicated replacement processes, and interrupted power generation during replacement are expected.

On the other hand, the conventional floating photovoltaic power generation device mostly uses a buoyant body made of metal or plastic. When using a buoyant body made of metal, corrosion occurs due to exposure to sea breeze or seawater, and thus has a bad appearance. There is a problem that durability is deteriorated, and rust due to corrosion is lost to the sea, causing environmental pollution. In addition, when using a buoyant body made of plastic, there was a problem of deterioration in durability due to shrinkage and expansion due to deformation and freezing due to ultraviolet rays and heat, and microplastics were lost due to continued friction while being continuously exposed to the wool or blue. The problem occurred. As these lost microplastics were detected in sea creatures such as oysters, mussels and blue crabs, food stability was seriously threatened.

For this reason, conventional floating photovoltaic devices using a buoyant body made of metal or plastic have to be installed in a place that can minimize the effects of wind, swell, blue, etc., such as dams, reservoirs, freshwater lakes or drainage reservoirs. Therefore, there was a problem that the space was limited during construction.

The pants 10 are suspended in water at a predetermined depth from the water surface to prevent exposure to the water surface to minimize contact with environmental factors such as wind, blue, or wool.

For example, the pants 10 may be suspended at a depth of at least 3 m or less from the water surface, and the mooring line 11 and the weight of the bottom of each corner of the pants to prevent the pants from being arbitrarily injured Weight 12 is provided.

The pants may have appropriate dimensions to ensure sufficient buoyancy without being affected by the size or shape of the water structure, for example, may be 50m long, 50m wide, 2m high, and secure sufficient buoyancy. You can.

In addition, the pants 10 can reduce the manufacturing cost and can be made of a suitable material to ensure easy transportation and durability for on-site construction.

In addition, the pants 10 is a tension control winch that adjusts the tension of the mooring line so that it floats below the water surface while maintaining an appropriate distance from the water surface for factors such as water level fluctuations, changes in flow, and wind effects. 18) may be provided. The operation principle or effect of the winch will be described later.

In addition, a separate auxiliary frame (not shown) for connecting a plurality of support frames forming the same row or the same column in the longitudinal or transverse direction may be provided on the support frame 20.

FIG. 5 is a photograph showing a problem caused when a floating body providing buoyancy according to the prior art is floated on the water surface and the exposed portion of the water surface is exposed to environmental factors including wind, swell, and waves. 11) and the weight (12) as a medium to ensure that the pants 10 are suspended in the water at a predetermined depth from the surface to minimize the exposure to the environmental factors, thereby ensuring the durability of the pants 10, It is possible to make the solar power generation device float more stably.

In addition, the solar power generation device can be installed even in the sea where the environmental effects such as wind, tide, or waves can be affected through these effects, and thus there is a remarkable effect of utilizing a vast surface of water.

In addition, the support frame 20 according to the present invention has excellent strength to ensure durability, excellent corrosion resistance to prevent corrosion, and can be made of a suitable material to facilitate transport or field construction, For example, it may be formed of a material such as POSSMAC, stainless steel (SUS), carbon fiber, or carbon steel.

Here, Posmac (POSMAC) is a corrosion-resistant iron plate composed of aluminum, manganese, and zinc plated on a general steel plate, and has a corrosion resistance of 5 to 10 times that of a zinc steel plate. It is used, and a detailed description will be omitted below.

In addition, the support frame 20 is preferably anticorrosive to prevent corrosion by sea breeze or sea water when installed on the sea.

Next, the present invention can be arranged in a plurality of the pants 10 in a grid form to increase the light collection amount to improve the power generation efficiency, due to the collision between the pants and two adjacent pants between the pants A damper 40 may be provided to prevent breakage or damage.

Referring to FIG. 2, the damper 40 is composed of a cylindrical body 41 in charge of appearance and a cable 42 provided inside the body.

It is preferred that the material is made of a material having strength (for example, steel).

Conventionally, a plurality of photovoltaic devices were sequentially fixed along a longitudinal or transverse direction by fastening a bracket made of a metal material protruding outward with a bolt or by welding a metal material frame having a predetermined length.

However, the construction structure in the form of fastening bolts to the bracket causes a problem that the fastening force of bolts and nuts gradually decreases when used for a long time due to environmental factors such as wind or waves, and is exposed to sea wind or sea water and is durable due to corrosion. It must be degraded. In addition, the construction structure in the form of welding the metal frame by welding is used in large quantities depending on the installation scale of the photovoltaic device, so the manufacturing cost is inevitably increased.

It is possible to ensure the stability of the photovoltaic device by making it variable.

As described above, the pants 10 are in a state fixed to a predetermined depth from the water surface through the mooring line 11 and the weight 12, so that the solar power generation device is not in the water unless it is raised or lowered in response to a change in water level. As it is locked or a part of the pants 10 is exposed to the outside, it may be exposed to environmental factors such as wind, wool, blue, etc., thereby deteriorating durability and overturning due to an increase in water resistance.

In order to prevent this problem, the present invention is installed on the upper side of the support frame 20 protruding above the water level sensor 14 for detecting the water level, the ballast water (W) on one side of the pants 10 Flow control port 15 is provided with an opening and closing valve for filling the, and when the water level increases, a pump 16 and a discharge pipe 17 for discharging the ballast water filled in the pants to the outside may be provided.

Conversely, when the water level is lowered, the control unit drives the motor of the winch 18 in the reverse direction so that the mooring line is wound so that the pants 10 descend by a predetermined depth or the flow rate adjusting device 15 is opened through an opening / closing valve. By filling the ballast water (W) additionally inside the pants 10, the pants 10 can be lowered by a predetermined depth.

The order in which the motor or pump 16 of the winch 18 is driven may be set through a control unit in consideration of various requirements of the place where the photovoltaic device 30 is constructed, and sequentially the motor or pump of the winch. Can be driven or driven simultaneously.

Through this configuration, the present invention can effectively prevent a rollover accident caused by a change in water level when a solar power generation device is installed in a place where a change in water level occurs more frequently than in the sea, such as a dam or reservoir, a fresh water lake, or a reservoir. Can be expected.
