It is possible, easy to manage, and to a structure mooring structure of a floating solar power generation device that can be installed at low cost.

Photovoltaic power generation is a method of generating electricity using light energy from the sun. When light energy is irradiated to a photovoltaic cell, electrons flow through the photovoltaic cell to produce electricity.

The solar power generation device is configured to produce a large amount of electricity by connecting several solar panels (modules) made by connecting several photovoltaic cells.

In order to install the photovoltaic device on land, it requires enormous land purchase costs, and if it is installed on a hill or hillside where sunlight is well reflected, there is a problem that the natural environment is destroyed. In recent years, interest in floating solar power generation devices installed on water such as lakes, rivers, ponds, and seas is increasing.

Next, a preferred embodiment of the mooring structure of the floating photovoltaic device according to the present invention will be described in detail with reference to the drawings.

The present invention can be implemented in various forms, and is not limited to the embodiments described below.

Hereinafter, in order to clearly describe the present invention, detailed descriptions of parts that are not closely related to the present invention are omitted, and the same or similar elements are denoted by the same reference numerals throughout the description of the present invention, and repetitive descriptions are omitted. .

First, the structure mooring structure of the floating photovoltaic device according to an embodiment of the present invention, as shown in Figs. 1 and 2, a plurality of horizontal lines 10 and vertical lines 20, and a plurality of line fixtures 40 ), and a plurality of mooring fixtures (60).

The horizontal lines 10 and the vertical lines 20 are arranged at regular intervals in the horizontal and vertical directions under the floating structure and installed in a grid shape.

As the horizontal line 10 and the vertical line 20, a rope or wire rope made of a synthetic resin material may be used.

In the case of using a wire rope as the horizontal line 10 and the vertical line 20, it is preferable to use a wire rope coated to prevent corrosion.

When a carbon fiber material is used as the horizontal line 10 and the vertical line 20, since it has excellent tensile strength, safety can be improved.

In the above, when the horizontal line 10 and the vertical line 20 are made of polypropylene fiber, the horizontal line 10 and the vertical line 20 have a floating force to float in water, and are excellent in strength and durability. have.

The floating structure includes a buoyancy body 4 installed to support the solar panel (module) 2 in a floating state on the water surface.

The row fixture 40 fixes all or part of the intersection of the horizontal row 10 and the vertical row 20.

As the line fastener 40, a wire clip, a cable tie, a fixing band, a fixing clip, etc. may be used.

3 and 4 illustrate an example of using a wire clip as the string fastener 40.

For example, as shown in Figs. 3 and 4, the string fastener 40 is formed in a U-shape and a crimping member 42 having male screw portions 43 formed at both ends thereof, and the crimping member 42 Both ends of the coupling block 44 is inserted through and a space in which the horizontal line 10 and the vertical line 20 are inserted between the pressing member 42 is formed, and the compression member at the bottom of the coupling block 44 It comprises a fixing nut (48) coupled to both ends of (42).

Both sides of the coupling block 44 are formed with coupling holes 45 through which both ends of the crimping member 42 are inserted vertically, and between the crimping member 42 and the upper surface of the coupling block 44 A concave portion 46 is formed to form a space in which the horizontal line 10 and the vertical line 20 are located.

When the intersection of the horizontal line 10 and the vertical line 20 is fixed using the line fixing tool 40 configured as described above, the horizontal line 10 and the vertical line 20 do not slide left and right with each other. The intersection is tightly fixed.

And, as shown in Fig. 5, the horizontal line 10 and the vertical line 20 are installed in a state close to the floating structure by using a floating fixture 80 installed to fix the buoyancy body 4 of the floating structure. It is desirable to do.

The floating fixture 80 can also be implemented using a chain.

When the floating fixture 80 is used as a chain, it is fixed to support the horizontal line 10 or the vertical line 20 by using a fastening member 90 such as a bolt.

For example, in a state in which the chain, which is the floating fixture 80, is suspended from the upper surface of the buoyancy body 4 to both sides, the horizontal line 10 or the vertical line 20 is wound from the bottom, and then the end of the chain is stretched. By fixing the fastening member 90 to the floating portion, the horizontal line 10 or the vertical line 20 can be supported so that it is installed across the bottom surface of the buoyancy body 4.

When supporting the horizontal line 10 or the vertical line 20 so as to cross the bottom of the buoyancy body 4 as described above, the horizontal line 10 or the vertical line 20 is supported in a state that can move left and right. Compared to (10) or the method of fixing the vertical line 20 to the buoyancy body 4, it is possible to respond effectively even when the load is concentrated and act, and the breakage of the buoyancy body 4 can be prevented.

In addition, the mooring fixture 60 connects and fixes the mooring line 6 connected to the anchor 8 and the ends of the horizontal line 10 and the vertical line 20.

For example, the mooring fixture 60 may be configured in a ring shape to fix the mooring line 6 and the ends of the horizontal line 10 or the vertical line 20.

In addition, without using a separate mooring fixture 60, the end of the horizontal line 10 or the vertical line 20 is formed in a ring shape, and then the end of the mooring line 6 is placed in the horizontal line 10 or the vertical line. It is also possible to fit and fix the ring shape formed at the end of (20).

In addition, instead of using the mooring fixture 60, it is also possible to configure the end of the mooring line 6 to be fixed to the line fixture 40 that fixes the intersection of the horizontal line 10 and the vertical line 20. Do.

In addition, as shown in FIG. 6, the mooring fixture 60 may be provided with an elastic portion 64 whose length is changed according to the tension acting on the mooring line 6.

For example, the mooring fixture 60 includes a tubular body 62 with both ends closed, an elastic part 64 inserted into the body 62 and having a variable length, and the elastic part ( 64), a support plate 65 installed at one end of the body 62 and movably inserted into the body 62, and one end is fixed to the support plate 65 and the other end is one of the body 62 In the body 62, the elastic action line 67 exposed to the outside of the end surface, and a rechet 68 installed at the end of the elastic action line 67 and fixed by pulling the end of the mooring line 6 tautly. It is also possible to include a connecting ring 66 formed in a ring shape so as to be installed on the opposite end surface of the recess 68 and to fix the ends of the horizontal line 10 or the vertical line 20.

When the mooring fixture 60 is configured as described above, when the buoyant body 4 shakes and moves along the boom, the elastic action line 67 is pulled when the mooring line 6 is tensioned. The elastic portion 64 is compressed and its length is changed.

Therefore, it is possible to keep the tension acting on the mooring line 6 constant, and it is possible to effectively prevent excessive tension acting on the mooring line 6.
