Description

{SUN TRACKER FLOATING ON WATER}

The present invention relates to an aquatic solar tracking apparatus, and more particularly, to a solar-light tracking apparatus for estimating an irradiation direction of sunlight by sensing the amount of sunlight and controlling the solar- .

As the problem of environmental pollution arises due to the depletion of existing energy resources and the emission of pollutants, development of clean and infinite alternative energy using natural environment such as sun, wind, and tidal force is being promoted.

Among these, the solar power generation system which receives solar heat through the solar cell to produce electric power and the solar power generation system which receives the solar light through the solar cell to produce electric power are being actively studied.

Generally, the solar power generation system is divided into a fixed solar power generation system and a tracking solar power generation system depending on the method of driving the solar panel. The stationary photovoltaic power generation system is a system in which the solar panel is fixed and the azimuth and elevation can not be changed. The tracking type solar power generation system is a system that can change the azimuth and elevation of the solar panel according to the position of the sun by itself.

The stationary photovoltaic system has a structure in which most of the solar panels are oriented to the south. After the solar panels are installed, the direction and tilt of the solar panels do not change. This fixed photovoltaic power generation system has the advantages of low initial installation cost and low operation and maintenance cost but it is designed to direct the solar panel only in the designated direction regardless of the position of the sun, It is disadvantageous in that it is not high.

To overcome these drawbacks, a tracking type solar power generation system that can change the direction of the solar panel according to the position of the sun has been developed.

The tracking solar photovoltaic system is equipped with driving means for rotating the frame, usually with a solar panel installed, in order to move the solar panel in order to increase the light collecting ability while tracking the moving sun until the sun goes up and down, It is designed to track the sunlight by rotating the frame so that the sun's position angle approaches the vertical according to the movement.

However, in order to install a tracking solar power generation system, a large site is required, which causes a problem that the initial facility investment cost is high to secure it. To solve these problems, a technique has been developed for installing floats on the surface of water such as rivers and lakes, and installing photovoltaic systems on floats.

However, the conventional photovoltaic system installed on the floating surface of the water surface is merely a fixed solar photovoltaic system used on land or a tracking photovoltaic power generation system installed directly on the surface of the water. This has the problem of damaging the natural landscape of rivers and lakes due to huge floats and negatively affecting the ecosystem.

On the other hand, in order to solve such a problem, even if a solar power generation system installed on a floating surface of the water is manufactured as a small unit device, when a conventional solar tracking device is applied, the suspension for supporting a heavy solar tracking device is miniaturized And it is difficult to adjust the inclination of the suspended body when the weight of the solar panel tilted by the solar tracking is tilted to one side due to the supporting structure floating on the water surface instead of the ground. In addition, if natural phenomena such as frequent strong winds or typhoons occur in rivers or lakes, the fixed state in the water is unstable, which can lead to accidents that can be turned upside down.

Furthermore, when the water is free, the solar panel can not move in a fixed state on the frozen water surface, but solar tracking is performed, so that a mechanical device for tracking the sunlight, for example, driving means (driving motor) And the like may be damaged.

A prior art related to the present invention is Korean Patent No. 10-1101316 (registered on December 26, 2011).

Considering the environment of water, a water solar tracking system that minimizes the complexity of mechanical devices for tracking sunlight by using buoyancy to track sunlight is proposed.

The plurality of fixed wires 30 serve to connect and fix the solar panel 110 floating on the water W to the land L. [ The plurality of fixed wires 30 may be connected to the fixing member 32 whose one end is connected to the upper surface 11 of the solar panel 110 and the other end is fixed to the land L. [ The plurality of fixing wires 30 fix the solar panel 110 to the land so that the solar panel 110 floating in the water must be originally positioned due to the flow of water, Thereby preventing or preventing the user from leaving the place. It should be noted that the shape in which the solar panel 110 is fixed to the land by a plurality of fixing wires 30 in the drawing is only one embodiment and is not limited thereto.

The solar light sensing unit 50 is attached to the solar panel 110 to sense sunlight. The solar photodetector 50 may include at least one first photosensor positioned on a first axis (X-axis) of the upper surface 11 of the solar panel 110 to sense sunlight And a second optical sensor positioned on a second axis (Y axis) of the upper surface 11 of the solar panel 110 and sensing solar light, And a second axis sunlight sensing unit 52 provided on the first axis. The first axis solar detection unit 51 and the second axis solar detection unit 52 may have the same structure as shown in FIG. Accordingly, only the structure of the first axis sun light sensing unit 51 will be described.

5, the first axis sunlight sensing unit 51 includes at least one first photosensor 112, 113, 114, and 115 on a hemispherical support unit 111.

The at least one first photosensor 112, 113, 114, and 115 may include an electric device that generates a current by detecting solar light such as a phototransistor, a photodiode, a CDS, and a solar cell. Between the at least one first photosensor 112, 113, 114, and 115, barrier ribs 116a, 116b, and 116c are formed. The barrier ribs 116a, 116b and 116c are radially extended from the hemispherical support 111 so that light emitted from the first photosensors 112, 113, 114, In order to prevent light from being emitted to the first optical sensors. At this time, a partition wall 116a is provided on a surface facing the sun. The material of the barrier ribs 116a, 116b, and 116c is a light absorbing material that does not reflect or scatter light. The partition walls 116a, 116b, and 116c are fixed by a case 117. [ The case 117 may also function as the partitions 116a, 116b, and 116c. Accordingly, it is appropriate to use a light absorbing material that does not reflect or scatter light, like the material of the partition walls 116a, 116b, and 116c.

On the other hand, the installation structure of the case 117 and the partition walls 116a, 116b, and 116c can be variously modified as needed. For example, in the drawing, the radius of the case 117 and the height of the partition walls 116a, 116b, and 116c substantially correspond to each other. However, the embodiment of the present invention is not limited thereto, and the radius of the case 117 may be longer or shorter than the height of the partitions 116a, 116b, and 116c. Further, although the case 117 is shown as a transparent material in the drawing, the embodiment of the present invention is not limited thereto, and the case 117 may be made of a non-reflecting material or a non-reflecting material with respect to light. The case 117 is made of a non-reflecting or impermeable material and the radius of the case 117 is appropriately adjusted so that each of the first photosensors 112, 113, 113, 114, and 115 of the first axis photodetector unit 51 can be irradiated to only the light beams irradiated from the front surface of the first axis photodetector unit 114, 115 and 115, respectively. By doing so, the light scattered or reflected from various directions (for example, side surfaces) is shielded against each of the first photosensors 112, 113, 114, and 115 of the first axis photodetector unit 51, The first optical sensors 112, 113, 114, and 115 of the first axis photodetector unit 51 are irradiated with only light, so that the directionality of optical sensing can be more precisely performed.

The first optical sensors 112, 113, 114, and 115 are disposed on the first optical sensors 112, 113, 114, and 115 of the first axis photodetector 51, At least a part of the lower portion of the support portion 111 may be recessed. That is, by forming a concave portion in the supporting portion 111 and forming the first optical sensors 112, 113, 114 and 115 in the concave portions, a lower portion of each of the first optical sensors 112, 113, 114, So that it can be recessed in the supporting portion 111.

The first optical sensors 112, 113, 114, and 115 are disposed on the first optical sensors 112, 113, 114, and 115 of the first axis photodetector 51, For example, shrinkable rubber material so as to effectively block the light irradiated to the side surfaces of the first optical sensors 112, 113, 114 and 115.

The first axis sunlight sensing part 51 is disposed on the upper surface 11 of the solar panel 110 so as to be perpendicular to the second axis solar light sensing part 52 on the upper surface 11 of the solar panel 110. [ Can be installed.

The wind direction / wind speed measurement unit 35 measures the wind direction and wind speed of the outside.

The emergency driving part 140 includes an auxiliary tank 141 formed in a cylindrical or polyhedral shape and positioned at the lower center of the float 120, an auxiliary pipe 141 connecting the open ends of the auxiliary tanks 121 142), and an auxiliary valve (143) for opening and closing water between the inner space of each support tank (121) and the auxiliary pipe (142).

The emergency driving part 140 opens all of the auxiliary valves 143 provided under the respective support tanks 121 in accordance with the safety control signal when the solar tracking device 100 is driven in the safety mode according to the emergency system. Then, the water W of each support tank 121 flows into the auxiliary tank 141 by the gravity, so that the solar panel 110 is kept horizontal in a short time. This can be confirmed by a sectional view showing the state of the aquamarine tracking apparatus when the aquamarine tracking apparatus is in a safe mode as illustrated in Fig. Although the solar panel 110 can be changed horizontally using the angle adjusting unit 130, since the angle adjusting unit 130 uses a small pump, a considerable time may be required to change the angle.

The water W in the support tank 121 serving as a weight is gathered in the auxiliary tank 141 positioned at the lowermost center of the aquaporadistic tracking device 100 so that the weight W is not dispersed, There is an advantage that it can maintain a safe horizontal state. The floating fluid 120 and the emergency driving part 140 described above may be made of metal or synthetic resin, and may be connected to each other through welding members and coupling members such as a flange, which are generally used for those skilled in the art. .

The control unit 40 generates the tracking signal so that the top surface 11 of the solar panel 110 faces the irradiation direction of sunlight using the light amount of the solar light sensed by the solar light sensing unit 50, And controls the generation of the safety control signal by grasping the external wind direction and wind speed measured by the wind speed measuring unit 35.

The aquamarine tracking apparatus 100 according to an embodiment of the present invention may further include a buoyancy sensing unit 60 for sensing the buoyancy of the float 120.

The control unit 40 sets the upper surface 11 of the solar panel 110 to be perpendicular to the irradiation direction of the sunlight so that the upper surface 11 of the solar panel 110 faces the irradiation direction of sunlight The buoyancy of the float 120 can be controlled until the buoyancy of the float 120 and the sensed buoyancy become equal.

The aquatic solar tracking apparatus 100 according to an embodiment of the present invention may further include a tilt sensing unit 70 attached to the solar panel 110 to sense the tilt of the solar panel 110.

The control unit 40 controls the temperature of the solar panel 110 such that the upper surface 11 of the solar panel 110 is perpendicular to the irradiation direction of the sunlight so that the detected inclination is directed toward the sunlight. The buoyant force of the float 20 can be controlled until the inclination of the upper surface, that is, the direction and angle in which the upper surface of the solar panel is tilted.

The water solar tracking system 100 according to an embodiment of the present invention may further include a temperature sensing unit 80 attached to the solar panel 110 to sense the temperature of water. At this time, it is preferable that the temperature sensing unit 80 is installed on the lower surface of the solar panel 110 to sense the temperature of the water. However, it is not limited thereto.

The control unit 40 can stop the buoyancy control of the buoyancy unit 20 when the temperature of the water sensed by the temperature sensing unit 80 is the water temperature. At this time, the water temperature of the water may be 0 ° C, but it is not limited thereto and may vary depending on the environment in which the solar panel 10 is installed.

This is because the water is frozen at the surface of the water, and the buoyancy control of the buoyancy portion 20 becomes meaningless. If the buoyant force of the buoyant portion 20 is continuously controlled in the case where the water is at a temperature that is free of water, buoyancy control of the buoyant portion 20 may cause breakage of the buoyants constituting the buoyant portion 20 .

Accordingly, when the temperature of the water drops below the water temperature, the control unit 40 stops the buoyancy control operation of the buoyancy unit 20 and can generate the first stop signal.

 According to the first stop signal, the emergency driving unit 140 may collect the water in the support tank into an auxiliary tank provided at the lower center of the float 120 to keep the solar panel 110 horizontal.

The aquamarine tracking apparatus 100 according to an embodiment of the present invention includes an illuminance detection unit 100 installed on an upper surface 11 of the solar panel 110 to detect the illuminance of the upper surface 11 of the solar panel 110, (90).

The control unit 40 may stop the buoyancy control of the buoyancy unit 20 and may generate the second stop signal when the illuminance detected by the illuminance detection unit 90 is less than the set illuminance.

When the detected illuminance is equal to or lower than the set illuminance, it is a cloudy day with many clouds or night.

According to the second stop signal, the emergency driving unit 140 may collect the water in the support tank into an auxiliary tank provided at the lower center of the float 120 to keep the solar panel 110 horizontal. The reason why the solar panel 110 is in a horizontal state with respect to the water surface is that the solar panel 110 is held horizontally when it is a cloudy day to maximize the amount of generated electricity. In the case of nighttime, It is impossible to generate electricity.

The control unit 40 compares the amounts of light of the respective solar rays sensed by the at least one first photosensor for sensing the sunlight and the at least one second photosensor, May be generated so as to be inclined in the irradiated direction of the estimated sunlight and transmitted to the angle adjuster 130.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
