1 is a perspective view of a floating solar power generating apparatus equipped with a mooring device according to an embodiment of the present invention.

As shown in the figure, the floating solar power generation apparatus according to the present embodiment is provided so as to generate sunlight by condensing solar light in a floating state. To this end, the floating solar power generation apparatus is provided with a solar cell module S for condensing solar light in the upper part, and a floating part 100 for floating the floating solar power generation device in the lower part And a body part 200 formed to support the solar cell module S is provided between the solar cell module S and the floating part 100.

A mooring device 300 is provided at the upper part of the base body part of the lower part of the body part 200 so as to maintain the fixed state of the floating solar photovoltaic device on the water surface and to restrict movement, .

FIG. 2 is a schematic view for explaining an operation of a mooring device according to an embodiment of the present invention.

Hereinafter, for convenience of explanation, the floating solar photovoltaic device will be described in a simplified manner.

As shown, the floating solar power generation apparatus is provided in a floating state on the water surface. A plurality of mooring devices 300 are provided at the four corners of the floating solar power generation device.

Each mooring device 300 is connected to the other side of a wire w to which one side is fixed to a concrete fixture (hereinafter collectively referred to as an underwater fixture (c)) provided in the water. That is, the mooring device 300 is provided on the opposite side of the underwater fixture c with respect to the wire w.

When one side of the wire w is fixed to the underwater fixture c and the mooring device 300 is connected to the other side of the wire w, w are wound up so as to keep the wire w in a tightened state.

That is, in a state where the wire (w) is loosely loosened, there is a possibility that the floating solar power generation device may drift or move indiscriminately on the surface of the water, so that the floating solar power generation device is prevented from moving in a fixed direction And then floated.

3 is a block diagram showing a configuration of a mooring device according to an embodiment of the present invention.

The mooring apparatus 300 according to the present embodiment includes a water level sensor 310, a drum 320, a winder 330, a light-condensing rate determiner 340, a storage 350, a controller 360, And a determination unit 370.

The water level sensor unit 310 serves to check whether the mooring device 300 is located vertically downward at the location where the mooring device 300 is located. That is, the water level sensor unit 310 measures the distance from the current point to the water fixture c located vertically below the water level.

The water level measured by the water level sensor unit 310 is provided for the purpose of winding or unwinding the wire w according to the comparison result with the measured water level.

The drum portion 320 is provided for winding the opposite end portion of the wire w fixed to the underwater fixture c. The drum portion 320 allows the wire w to be held in a tensioned state by winding the wire w.

The winding unit 330 is implemented by a motor or the like and serves to provide a rotational force for rotating the drum unit 320. [

The light-condensing-rate determining unit 340 determines the current light-condensing rate and provides the light-condensing ratio to be compared with the past data.

The storage unit 350 stores a driving program for driving the entire mooring apparatus 300 and a past history for winding the wire w through the comparison with the current number and used information measured in the water level sensor unit 310, Information on the light-condensing ratio of the current or past collected through the light-condensing rate determiner 340, and the like.

The direction determination unit 370 is provided for providing information on the directionality of the current mooring device through a gyro sensor, a compass, or the like.

The control unit 360 controls the water level sensor unit 310, the drum unit 320, the winding unit 330, the light-condensing rate determination unit 340, the storage unit 350, and the direction determination unit 370 .

Figs. 4 and 5 are views for explaining the operation of the mooring device when the number of vehicles is increased. Fig. For convenience of explanation, the shape and operation of a three-dimensional actual mooring apparatus will be described with reference to a two-dimensional plane.

As shown in Fig. 4, when the wire w2 on the right side is in a loose state for any reason, it means that the right hand side is in a lowered state. Thus, in a state in which the right hand side is lowered, the right side portion of the mooring device can move indiscreetly up or down or right and left.

Accordingly, the water level sensor unit 310 compares the previous information with the previous water level information about the changed water level information. If it is determined that the water level is lowered by 'a' The wire w2 of the wire W2 is further wound.

More specifically, as shown in FIG. 5, the drum portion 320 can wind the right wire w2 by rotating the drum portion 320 by the winding portion 330, w2 can be maintained in a restrained state.

As described above, the period during which the water level sensor unit 310 senses the water level may be preset by the user, but the water level sensor unit 310 may change the period of sensing the water level by using various information, .

6 is a view for explaining the procedure of resuming the water level according to the light collection rate.

The light collection rate is obtained by the light collection rate determination unit 340 as described above. As shown in the figure, when the light collecting ratio in the state where the light condensing rate is 1 minute is 50, the light collecting rate is 2 when the light condensing rate is 2 minutes, and the light collecting ratio is 40 when the light is 3 minutes, It can be judged that the light-condensing rate between the minute and minute has changed too rapidly.

Accordingly, the control unit 360 can regard the abrupt change in the light collecting rate as being caused by the unusual circumstances, thereby enabling the resumption of the water level detection to be performed.

That is, the light-condensing rate is rapidly changed because the water level suddenly drops or becomes high due to the sudden change in the water level. Therefore, the controller 360 checks the water level again at this timing.

FIG. 7 is a view for explaining a procedure of resuming the water level detection using the stored stored water concentration data.

As shown in the figure, if the light collection rate on July 14, 2014 is 50, and the light collection rate on July 14, 2015 is 30, which is one year later today, even though the date is the same, Can be judged to be too low.

Accordingly, the control unit 360 can consider the sudden drop in the light collecting rate due to the unexpected circumstances, thereby enabling the water level detection to be resumed.

That is, when the light-condensing rate is suddenly decreased, there is a possibility that the water level suddenly drops or becomes higher due to the sudden decrease in the water level, so that the control unit 360 again checks the water level at this timing.

8 is a view for explaining a water level resume procedure according to a change in position.

As described above, the floating solar power generation device and the mooring device refer to a device that maintains the floating state in the watercourse and continually attempts and performs solar power generation. Therefore, the floating solar power generation device or the mooring device is installed so that it does not need to move without any particular reason.

Nevertheless, if floating solar power generation equipment or mooring equipment is moved due to sudden currents or sudden changes in the weather, it is highly likely that the wire is stretched or loosened, and the solar power generation efficiency is greatly affected .

The direction determiner 370 determines whether the direction of the mooring device has been changed. If it is determined that the direction of the mooring device has been changed, the controller 360 can regard the change of the direction as due to unusual circumstances, Thereby enabling the resumption of sensing to be performed.

That is, if the direction is changed, there is a possibility that the water level suddenly drops or becomes high due to the sudden change in the water level, so that the control unit 360 checks the water level again at this timing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings .
