Hereinafter, an energy harvesting system using sunlight according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 3, the energy harvesting system using sunlight according to an embodiment of the present invention includes a base plate 110 on which a solar module 10 is disposed, a solar module 10 and a base plate ( It may include a plurality of actuators located between 110 and the control block 500 for controlling the actuator 120 and the support structure 20 for supporting the base plate 110.

For convenience of description, the base plate 110, the solar module 10, the actuator 120, and the control block 500 are defined as the upper structure 100 and will be described.

The base plate 110 serving as the support plate 311 of the upper structure 100 may be spaced apart from the ground by a support structure 20 to be described later. A solar module 10 formed with a plurality of solar panels 11 spaced apart from each other at regular intervals may be disposed on an upper surface of the base plate 110. At this time, the base plate 110 is arranged to be inclined by the support structure 20 to increase the light condensing effect of sunlight.

In this embodiment, the base plate 110 may be formed in the form of a plate, but a plurality of frames may also be formed in the form of a lattice structure.

A plurality of actuators 120 may be provided between each of the base plate 110 and the solar panel 11. One side of each of the actuators 120 is fixedly coupled to the base plate 110 and the other side can be coupled to the center of the solar panel 11.

At this time, the other side of the actuator 120 may be coupled to the center of the solar panel 11 and the hinge member 121. The reason why the other side of the actuator 120 is coupled by the central portion of the solar panel 11 and the hinge member 121 is that of the solar panel 11 corresponding to the variable of the curvature radius of the solar module 10 to be described later This is to make the slope variable.

In more detail, since each of the solar panels 11 is connected to a plurality of links 130 to be described later, when the actuator 120 operates in a direction orthogonal to the surface of the base plate 110, the solar module 10 ) May have a predetermined radius of curvature. At this time, since the solar panel 11 and the actuator 120 are hinged, the slope of the solar panel 11 may be changed corresponding to the radius of curvature of the solar module 10.

In this embodiment, each of the plurality of actuators 120 may vary the radius of curvature of the solar module 10 in response to the control signal transmitted from the control block 500 to be described later.

2 and 3, the solar module 10 may further include a plurality of links 130. The plurality of links 130 may serve to connect each of the solar panels 11 to have a radius of curvature.

In this embodiment, the link 130 connected between the photovoltaic panel 11 and the adjacent photovoltaic panel 11 may be composed of at least two or more, but the number of links 130 may be one or more.

For example, if the number of links 130 is composed of two rather than one, the variable rate of the radius of curvature of the solar module 10 can be more easily controlled. That is, as the number of links 130 increases, the radius of curvature between adjacent solar panels 11 may be more linearly controlled.

When the curvature radius of the solar module 10 is described in more detail, as illustrated in FIG. 2, the actuator 120 connected to the solar panel 11 disposed at the center of the solar module 10 is referenced. As the protruding degree of the actuators 120 located on the outside is sequentially shortened, the solar module 10 may have a radius of curvature of a shape in which the central portion protrudes.

Conversely, as illustrated in FIG. 3, the protruding degree of the actuators 120 positioned outside is sequentially based on the actuator 120 connected to the solar panel 11 disposed at the center of the solar module 10 sequentially. When lengthened, the solar module 10 may have a curvature radius having a concave shape in the center.

In this embodiment, the photovoltaic module 10 has a curvature in which the center is protruded or concave so that the center of the photovoltaic module 10 faces any of the east, west, north, or south directions in the manner described above. It can have a radius.

A control block 500 may be provided on the lower surface of the base plate 110. The control block 500 may serve to control each of the plurality of actuators 120 in response to time and weather information.

The control block 500 may receive meteorological information from a control center such as the Korea Meteorological Administration, or may sense meteorological information using a sensor provided by itself. Meanwhile, in the exemplary embodiment of the present invention, the case where the control block 500 controls the actuator 120 in response to time and weather information is illustrated, but the present invention is not limited thereto. As a modification, the control block 500 may control the actuator 120 according to the surface condition of the solar panel 11, for example, the amount of by-products attached to the surface of the solar panel 11. In this case, it is possible to prevent the light collecting efficiency from being lowered due to a by-product attached to the surface of the solar panel 11.

The time for the control block 500 to control each of the actuators 120 may be a time for the moving position of the sun until the sun rises. That is, the control block 500 may control the actuators 120 to correspond to the corresponding time, so that the radius of curvature is variable so that the center of the solar module 10 faces the sun.

In addition, the weather conditions for the control block 500 to control each of the actuators 120 may be when rain or strong wind blows. For example, the energy harvesting system using sunlight of the present invention can control the solar module 10 in a convex arch shape to remove rain or by-products on the surface of the solar panel 11 when it rains.

In addition, the energy harvesting system using sunlight can vary the radius of curvature to minimize the wind resistance of the solar module 10 when a strong wind blows.

Therefore, the energy harvesting system using sunlight according to an embodiment of the present invention can maximize the efficiency of condensing sunlight by controlling the radius of curvature of the solar module 10 according to time and weather conditions.

For example, the inclination angle and inclination direction of the base plate 110 may be adjusted according to the length of the post 200 supporting the base plate 110.

The post coupling means 300 may be installed such that one side is connected to the other side of the post 200 and the other side is fixed to the ground. The coupling means may serve to vary the height of the support 200 while one side connected to the support 200 is elevated.

The support coupling means 300 may be provided with a support plate 311. The support plate 311 may be formed in a direction parallel to the ground and fixed to the ground. The support plate 311 may be fixed through the ground (ie, the basic concrete) and the anchor.

In this embodiment, the support plate 311 may be installed on the ground, but may be installed on the roof of the building.

A support body 312 may be formed on the support plate 311. The support body 312 may be formed to extend in a direction in which one side is connected to the support plate 311 and the other side is orthogonal from the support plate 311. A sliding space 315 may be formed inside the other side of the support plate 311. A lifting body 320, which will be described later, may be inserted into the sliding space 315.

In addition, the first fastening hole 313 may be formed through the outside of the lifting body 320. A fixing member 400 to be described later may be fastened to the first fastening hole 313. The first fastening hole 313 may be formed to pass through to be inclined in either direction so that the fixing member 400 is fastened in the inclined direction.

In this embodiment, the first fastening hole 313 may be formed in a pair so that one fastening member 400 is fastened, but a pair of first fastening holes 313 so that a plurality of fastening members 400 can be fastened. ) May be formed in plural.

In this embodiment, a plurality of first fastening holes 313 may be formed along the longitudinal direction of the support body 312 or may be formed in a plurality of directions perpendicular to the longitudinal direction of the support body 312.

The lifting body 320 may be installed in the sliding space 315 of the support body 312 to be elevated. One side of the lifting body 320 may be installed in the sliding space 315 of the support body 312 and the other side may be formed with an insertion portion 321 for coupling with the post 200.

In the insertion portion 321 of the lifting body 320, the end of the post 200 may be coupled to the post 200 through the bolt nut C2.

One side of the elevating body inserted into the sliding space 315 of the support body 312 may be formed such that its cross section corresponds to the cross section of the sliding space 315. In addition, a second fastening hole 322 may be formed through one side of the lifting body 320 inserted into the sliding space 315 of the support body 312.

The second fastening hole 322 may be formed to pass through the same slope as the first fastening hole 313 on the extension line of the first fastening hole 313 to be fastened so that the fixing member 400 is inclined.

The fixing member 400 may sequentially pass through the first fastening hole 313 and the second fastening hole 322 to fasten the support body 312 and the lifting body 320.

The fixing member 400 is formed to extend to have the same slope as the first fastening hole 313 and the second fastening hole 322 so as to penetrate the first fastening hole 313 and the second fastening hole 322. 1 may include a fixed body (410). In addition, one side of the first fixing body 410 may include a first fixing head 420 protruding toward the longitudinal direction of the supporting body 312.

For example, after the first fixing body 410 passes through the first fastening hole 313 and the second fastening hole 322, the movement of the first fixed body 410 is limited by the first fixing head 420. Can be.

In the present embodiment, the first fixing body 410 and the first fixing head 420 of the fixing member 400 may be formed to have angles that are not orthogonal to each other. Here, the angles of the first fixing body 410 and the first fixing head 420 may correspond to the angles in the longitudinal direction of the first fastening hole 313 and the second fastening hole 322 and the support body 312. .

For example, the fixing member 400 can be fastened through the support body 312 and the lifting body 320 obliquely, so that the support body 312 and the lifting body 320 can be fastened with a simple operation. Even if there is no separate fastening member (for example, a nut) at the end of the 400, there is an effect that does not deviate from the support body 312 and the lifting body 320.

Meanwhile, a first stepped portion 314 may be formed in an inner direction on an upper portion of the support body 312. In addition, the second stepped 323 may be formed in the lower portion of the lifting body 320 in the outer direction. That is, it is possible to prevent the lifting body 320 from being separated from the support body 312 by the first stepped 314 and the second stepped 323.

Subsequently, after inserting the lifting body 320 into the sliding space 315 of the support body 312, the sliding space is made by passing the fixing member 400 through the first fastening hole 313 and the second fastening hole 322. In 315, the movement of the lifting of the lifting body 320 may be restricted. In other words, the height of the strut 200 can be adjusted by being fastened by the fixing member 400 in a state where the lifting body 320 is spaced as predetermined in the sliding space 315 of the support body 312.

If the first stepped 314 and the second stepped 323 are formed on the support body 312 and the lifting body 320 mentioned above, the lifting body 320 does not deviate from the support body 312. The lifting body 320 may be coupled to the holding body 200 and the lifting body 320 in a state where the lifting body 320 is inserted into the sliding space 315 of the supporting body 312.

Meanwhile, as illustrated in FIG. 7, a plurality of second fixing bodies 430 formed in the same manner as the first fixing body 410 may be formed in the fixing member 400. In addition, a second fixing head 440 connecting between one side of each of the second fixing bodies 430 may be included.

In FIG. 7, three second fixed bodies 430 are formed, but two or more second fixed bodies 430 may be formed.

In this case, the number of the first fastening holes 313 formed through the support body 312 may be formed to correspond to the number of the second fixing bodies 430. Therefore, the support body 312 and the lifting body 320 may be more firmly fastened by the fixing member 400 in which a plurality of second fixing bodies 430 are formed.

Inside the support member 610, an inner space for inserting one side of the post coupling means 300 may be formed. A support plate 311 of a support coupling means may be inserted into the inner space of the support member 610. For example, since the inner space is formed to extend in a direction parallel to the ground, the support plate 311 can be moved in the inner space in a direction parallel to the ground.

A moving member 620 may be provided between one side of the support coupling means 300 (that is, the support plate 311) and the bottom surface of the support member 610.

The corrosion preventing member 640 may be filled in the support member 610. The corrosion preventing member 640 may include oil. The corrosion-preventing member 640 including oil may not only prevent corrosion of the moving member 620, but may also serve as a lubricant for smoothly operating the moving member 620.

On the other hand, the upper surface of the support member 610 may be provided with a waterproof member 630 connected to one side of the holding means (300). The waterproof member 630 may be formed of a material having a waterproof effect. The waterproof member may serve to seal between the support member 610 and the post coupling means 300 from water or foreign substances.

Referring to FIG. 8, a seismic operation of an energy harvesting system using sunlight according to another embodiment of the present invention will be described. First, when an earthquake occurs at a position where the support structure 20 is installed on the ground, vibration due to the earthquake may occur in the support member 610.

In addition, the support plate 311 movably installed in the inner space of the support member 610 has a separate movement from the support member 610 by the moving member 620 to be moved in the inner space when vibration occurs on the ground. You can.

Therefore, since the support member 610 and the support plate 311 have separate movements, even if vibration due to an earthquake occurs in the support member 610, the propagation of the vibrations to the support coupling means 300 is prevented so that the upper structure (20) can be prevented from being damaged.
