Generally, photovoltaic power generation refers to a power generation method using the principle that electricity flows through the movement of electrons generated when light energy is injected into a solar cell composed of a semiconductor.

Such solar power generation uses solar energy provided for an infinite amount of time, so it does not incur fuel costs and does not cause pollution such as air pollution or waste generation.

However, it is pointed out that the initial investment cost, high power generation cost, and the need for a large installation area are limitations.

Recently, a method of installing a photovoltaic device in a river or a lake has been attracting attention in order to solve such a mounting area problem, and there have been successful cases of commercialization, but there has not been an attempt to install it in the sea yet. Many difficulties are expected due to the harsh environment.

In the above-mentioned Korean Patent Registration No. 10-1318791, Device "is used to adjust the supporting rope according to the water level so as to stably support float and solar power generation facilities on the water phase, but when the wind pressure is higher than the reference level, the supporting rope is fixed to prevent the floating float from drifting .

In addition, in Korean Patent Laid-Open Publication No. 10-2014-0077258, the " supporting structure of a photovoltaic power generation apparatus "in which the float can be floated in a state of being fixedly supported on the surface of the float, It is possible to maintain the position and the angle of receiving the sunlight constantly by installing the rotary frame, thereby improving the power generation efficiency and reducing the load of the rotary frame by using the flow of water , The above-mentioned Korean Patent Laid-open Publication No. 10-2015-0006520, "water-mounted solar power generation system", the strength of the bracket and the buoyant material is increased to prevent the floating matter from being damaged by the waves, It is possible to construct a large-scale power generation system by connecting in parallel so that a large amount of power can be produced A device has been proposed.

However, the above-mentioned conventional techniques have been proposed for the purpose of being installed in calm rivers or lakes compared with the sea, and have problems in that the wind speed and the flow velocity are fast and the durability to be installed in the sea where the wounds are generated has not been developed.

Therefore, there is a problem in that excessive tension is applied to the rope fixing the buoyancy structure due to rapid and frequent changes in the water level and the flow rate, and a problem in which the connection portion for connecting the plurality of buoyancy structures due to the swell is damaged. A marine buoyancy structure for mounting an optical module is required.

The buoy frame 100 is a component for placing various components of the offshore buoyant structure for mounting a solar module according to the present invention on the water surface and below the water surface, and is formed in a plate shape.

At this time, the plate shape may be any shape such as a square shape as well as a circular shape, and the outer line may be maintained, and a certain portion may be formed in a shape where the overall plate shape is maintained.

Since the buoy frame 100 is formed in a plate shape, water may be accumulated at the upper end due to a wave or rain.

Particularly, it is not preferable that the contact of the buoy frame 100, which may be composed of seawater and metal, is long since the seawater contains salt, so that, as shown in FIG. 2, One or more tapered holes 101 penetrating the upper and lower ends may be formed.

The taper hole 101 is formed to have the same area as the upper end and the lower end of the taper hole 101. Unlike the general through hole in which the inner hollow has a constant cross sectional area, And is formed to be wide.

Therefore, rainwater, seawater, and the like, which are seated on the upper end of the buoy frame 100, are easily discharged downward through the taper hole 101. However, the bottom of the buoy frame 100 is not easily raised Structure.

The solar module 110 fixed to the upper end of the buoy frame 100 is a known solar module and is mounted on the buoy frame 100 so as not to hinder the buoy frame 100 from being balanced on the water surface. It is preferable that an appropriate model is selected in consideration of the area and the shape of the area.

In addition, since the sea buoyant structure for installing a solar module according to the present invention is composed of a plurality of the buoy frames 100, a connecting member 120 for connecting the buoy frames 100 to each other must be provided.

3, the connecting member 120 has one end connected to one end of one buoy frame 100 and the other end connected to one end of another buoy frame 100, (100) are integrally formed as connectors for forming a floating buoyant structure for mounting a solar module according to the present invention.

As shown in FIG. 4, the connecting member 120 is formed in a symmetrical shape with respect to a virtual center line passing through the upper and lower ends of the through hole 121 in the shape of a curve passing through the upper and lower ends, And a joint connecting member 123 formed on both sides of the through hole 121 and having an opening 122 communicating with the outside at one side and the other side of the outer circumference with respect to the center line, do.

In FIG. 4, the joint connecting member 123 is formed in a cylindrical shape, but it is obvious that the joint connecting member 123 may have various shapes.

4, the connecting member 120 has a fastening shaft 124 that moves along the through hole 121 as a component, passes through the opening hole 122, And a universal joint 125 coupled with the shaft 124 as one component.

The fastening shaft 124 may have a shape having a width greater than that of the through hole 121 at both ends so as not to be separated from the through hole 121 through the through hole 121.

The fastening shaft 124 is not separated from the through hole 121 by the release preventing portion but the release preventing portion is not configured to fasten the fastening shaft 124 to one point so that the fastening shaft 124 Are movable along the through-holes 121 in a curved shape.

The fastening shaft 124 is configured to pass through a part of the universal joint 125 which is inserted into the joint connecting member 123 through the opening hole 122. With this configuration, (124) connects the universal joint (125) and the joint connecting member (123).

The universal joint 125 is provided to cope with a tensile force applied to the connecting member 120 when the buoy frame 100 on one side moves in a direction higher or lower than the buoy frame 100 on the other side by waves or the like The shape of which can be variously formed, but its function is the same as that of a known universal joint.

The joint connecting member 123 may be configured to cope with the tensile force applied to the connecting member 120 when the buoy frame 100 on one side moves to the left or right side of the buoy frame 100 on the other side, And the like.

That is, the universal joint 125 can prevent the tensile force generated by the upward or downward movement of the buoy frame 100 on one side of the buoy frame 100 on the other side from damaging the connecting member 120 And a tensile force generated by movement of the other side of the buoy frame 100 to the upper side, left side, or right side of the buoy frame 100 on one side relative to the connecting member 120, To prevent it from being broken.

The operation of the connection member 120 due to the movement of the buoy frame 100 will now be described in more detail.

5 (a) is a plan view showing a state of the connection member 120 in a state where the floating buoyancy structure for installing a solar module according to the present invention is not moving.

When no movement occurs in each of the sub-frame frames 100, since the intervals between the sub-frame frames 100 are the same, the connection member 120 maintains the state shown in FIG. 5 (a).

5 (b) is a plan view showing a state of the connecting member 120 when the sea buoyant structure for mounting a solar module according to the present invention is shaken to the left and right.

5 (b), when the buoy frame 100 on one side is moved to the left or right side of the buoy frame 100 on the other side by waves or the like, the universal frame 100 connected to the buoy frame 100 on one side The joint 125 is moved together and the fastening shaft 124 coupled to the universal joint 125 is moved to the left or right along the through hole 121. [

5C is a side view of the connection member 120 when the sea buoyant structure for mounting a solar module according to the present invention is shaken up and down.

5 (c), when the buoy frame 100 on one side moves in the direction higher or lower than the buoy frame 100 on the other side due to a wave or the like, The joint 125 is bent upward or downward.

Since the universal joint 125 is smoothly bent upward or downward, only the universal joint 125 is bent independently, and the movement of the fastening shaft 124 does not occur.

Therefore, the buoyant buoyant structure for mounting a solar module according to the present invention is provided with the connecting member 120, thereby solving the sagging and hogging phenomenon caused by the swell.

In addition, since the sea buoyant structure for installing the solar module according to the present invention is located on the water surface of the river, lake and sea as described above, the buoyancy member 130 must be included as a means for flooding the water.

The buoyancy member 130 supports the weight of the buoyancy frame 100 and the solar module 110 and can be easily floated in water. However, the buoyancy member 130 is most effective in terms of cost reduction and durability, It is preferable that it is configured in the form of a rubber tube.

It is obvious that the buoyancy member 130 should be fixed to the lower end of the buoy frame 100 and the same number or more may be provided depending on the number of the buoy frames 100 constituting the present invention, The deployed form can also be configured in a variety of ways.

FIG. 2 is an embodiment showing the buoyancy member 130 fixed to the lower end of the buoy frame 100.

As shown in FIG. 2, the buoyancy member 100 supports the buoy frame 100 most stably in consideration of installation cost and stability. The buoyancy member 100 can be floated on the water surface, Each of which is located at the end.

As described above, since the offshore buoyancy structure for installing the solar module according to the present invention is located on the water surface, it has mobility according to the flow of water.

Therefore, if the buoyant structure is not provided with a means for keeping the buoyant structure constant, problems such as collision with the feature or movement due to the movement of the water to the distant sea, A means is required.

6, an anchor portion 150 of a weight chain is installed on a floor surface under a water surface at which a sea buoyant structure for installing a solar module according to the present invention is to be located, as a means for solving the above problems. do.

It is obvious that the weight of the anchor part 150 should be different according to the total weight of the buoyancy structure.

At this time, the buoyant structure can be prevented from being connected with one of the anchor parts 150, but connecting the plurality of anchor parts 150 with the buoyant structure is more stable in structure and dispersion of tension something to do.

Since the movement of the buoyant structure can not be prevented by only the anchor part 150, the float 160 floating on the water surface as the means for preventing the buoyant structure from moving together with the anchor part 150, And a spring rope 170 for connecting the float 150 and the float 160.

When the float 160 needs to move the buoyancy structure due to maintenance or the like, the float 160 maintains the position of one end of the spring rope 170 on the water surface and then connects the anchor portion 150 and the buoyancy structure Which is connected to the buoyancy structure at one side thereof.

As shown in FIG. 6, as a connecting means for connecting the buoyant structure and the float 160 to each other, a first magnetic body 140 composed of a permanent magnet is provided on one side of the buoy frame 100 And a second magnetic body 161 attached to the first magnetic body 140 with respect to the first magnetic body 140 may be provided on one side of the float 160.

The first magnetic body 140 has an S pole on one side and an N pole on the other side, and one of the S pole and the N pole is disposed toward the buoy frame 100, (100).

Since the second magnetic body 161 is also a permanent magnet, it has an S pole on one side and an N pole on the other side. The pole opposite to the pole of the first magnetic body 140 disposed toward the outside of the buoy frame 100 It must be disposed toward the outside of the float 160.

Accordingly, the first magnetic body 140 and the second magnetic body 161 can be attached to fix the buoyancy structure to a predetermined position, and the first magnetic body 140 and the second magnetic body 161 can be attached and detached The buoyant structure can be moved to a desired position.

The spring rope 170 has one end connected to the anchor 150 and the other end connected to the float 160 to connect the anchor 150 and the float 160 to each other And the spring rope 170 connecting the buoy frame 100 and the anchor part 150 in a marine environment in which the wind speed and flow velocity are rapidly and frequently changed, It is possible to cope with.
