Solar power generation as a new and renewable energy power generation in the spotlight in recent years has a number of problems related to the selection of a location to install facilities for photovoltaic power generation. For example, when using a mountainous area, problems such as reduction of forest resources, damage to the ecosystem, and leakage of soil may occur.When installed on a building, problems such as safety problems of the building and obstruction of the view due to the shade caused by the solar panel may occur. Can occur.

As an alternative to overcome these problems, floating solar power has recently attracted attention. Accordingly, various technologies have been developed in connection with a method of mooring a solar power generation facility on the water surface. Recently, cases of mooring a solar power generation facility on the water using an elastic rope are gradually increasing.

However, conventional mooring devices using elastic ropes allow the photovoltaic power generation facility to be maintained without shaking even when the water level fluctuates due to the elasticity of the elastic rubber to maintain the water level difference that varies from time to time. When the elastic rope is broken due to changes in external weather conditions, such as, the floating photovoltaic power generation facility, which has to be used for a long period of 20 years or more, does not reach its end of life and floats or is damaged.

In addition, in the case of conventional mooring devices using an elastic rope, when the elastic force of the elastic rope decreases due to long-term use and needs to be replaced, it is difficult to moor at the position where the floating photovoltaic power generation facility is installed due to the imbalance of the force acting on the elastic rope. There is a problem that it is difficult to replace the rope.

However, the present invention may be implemented in various forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are attached to similar parts throughout the specification.

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

Referring to FIG. 1, in the floating device for an aquatic photovoltaic power generation facility according to a first embodiment of the present invention, a floating part 100 for supporting the floating photovoltaic power generation facility, and a floating part 100 are in a predetermined range area. A Tetrapod-shaped mooring part 410 that provides a fixing force to float within, a first connection line 420 formed of an elastic body having a tensile force to connect the floating part 100 and the mooring part 410, a floating part The second connection line 430 and the first connection line 420 that connects 100 and the mooring part 410 in the vertical direction are formed to have a length greater than or equal to the maximum tensile length to connect the floating part 100 and the mooring part 410 A third connection line 460 may be included.

First, referring to FIG. 2, the floating part 100 according to the first embodiment of the present invention includes a buoyancy body 200 in which a plurality of fillers are embedded, an upper support body on which an aquatic solar power generation facility is to be installed, an upper support body and buoyancy. It may include a lower support body 101 for connecting the sieve 200. At this time, the fillers embedded in the buoyancy body 200 are formed in a hexagonal shape, thereby stably absorbing an external shock to prevent damage and simultaneously provide buoyancy to the buoyancy body 200. The floating part 100 having such a structure may be used for floating solar power generation facilities, floating piers, floating offshore, offshore fishing grounds, offshore pensions, buoyant breakwaters, and buoyant footbridges.

Mooring unit 410 according to the first embodiment of the present invention is a configuration of the anchor (anchor) role required for the floating unit 100 to stably moor within a predetermined range, the environment and topography of the underwater floor, etc. It can be formed into a tetrapod shape that can be considered and changed in design. When the mooring unit 410 is formed in a tetrapod shape as described above, even when the underwater wave energy increases due to deterioration of external weather conditions, etc., the wave energy applied to the mooring unit 410 itself is reduced, thereby preventing a push phenomenon due to impact. Can be prevented. In addition, when the mooring part 410 is formed in a tetrapod shape, the initial construction within a predetermined range may be more easily performed through a stable structure having a low center of gravity.

The first connecting line 420 according to the first embodiment of the present invention is configured to stably accommodate the vertical vibration of the wave in the floating part 100. Since water vibrates at a constant frequency and generates waves even when external weather conditions change as well as when external weather conditions do not change, the floating part 100 moves in accordance with these waves in order to prevent shock caused by waves. You should be able to. Accordingly, the first connection line 420 may be formed of an elastic body having a tensile force for the movement of the floating part 100 to prevent an impact due to waves. For example, the first connecting line 420 is formed of an elastic rope and a polyester rope that can be returned to the original state by buffering the force with a mooring solution in a stationary state even in a 120 horsepower hurricane, gust, air pressure change, and waves. Can be.

The second connection line 430 according to the first embodiment of the present invention is a configuration for stably transmitting the fixing force provided by the mooring unit 410 to the floating unit 100 in the vertical direction. Since the fixing force provided by the mooring unit 410 is the gravity acting on the mooring unit 410, the floating unit 100 is stable within a predetermined range by fully utilizing the fixing force to prevent the movement of the floating unit 100. In order to be able to moor, the second connection line 430 may be coupled to the upper center of the mooring part 410 to connect the floating part 100 and the mooring part 410 in a vertical direction.

At this time, the first connection line 420 may be formed of an elastic body and may have a longer length compared to the second connection line 430, but when the height of the wavelength exceeds the maximum tensile length of the first connection line 420, the first connection line (420) can also be broken. To prepare for these problems, the third connection line 460 may be formed to have a length greater than or equal to the maximum tensile length of the first connection line 420.

As the above-described second connection line 430 and third connection line 460, an oval-ring malleable cast iron anchor chain block is used to withstand changes in wave height and industrial chains for ship mooring (ie, anchor chain). Can be used. In this way, when the anchor chain is used as the second connection line 430 and the third connection line 460, there is an advantage that the entire length can be appropriately adjusted by removing some rings, and only the part can be replaced even when a part is worn or cracked.
