Description

[0001] The present invention relates to a photovoltaic power generation apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation device, and more particularly, to a solar power generation device capable of increasing power generation efficiency by adjusting an altitude angle of a solar cell panel according to the altitude of the sun.

Alternative energy is being developed as fossil fuels such as petroleum and coal are depleted. In particular, alternative energy using solar energy is actively being developed.

Power generation technologies that utilize solar energy to produce electricity include solar power generation that uses solar heat to drive a heat engine to generate electricity, and solar power that generates electricity from solar cells using solar light.

Here, a solar cell used for solar power generation includes a semiconductor compound element that converts sunlight directly into electricity.

In the solar cell used for the solar power generation, silicon and a composite material are usually used. Specifically, a solar cell uses a P-type semiconductor and an N-type semiconductor in combination, and utilizes a photoelectric effect that generates electricity by receiving sunlight.

Most of the solar cells are composed of large-area P-N junction diodes, and the electromotive force generated at the opposite ends of the P-N junction diode is connected to an external circuit.

The minimum unit of such a solar cell is referred to as a cell. Actually, the solar cell is rarely used as a cell.

This is because the voltage from one cell is very small, about 0.5 V, compared to several tens or hundreds of volts (V) of voltage required for practical use. This is why a plurality of unit solar cells can be connected in series or parallel It is connected and used.

In addition, when the solar cell is used outdoors, it is subjected to various harsh environments. Therefore, in order to protect a large number of cells connected with a necessary unit capacity in a harsh environment, a solar cell module .

However, since the solar cell module must be used in a large amount in order to obtain a constant electric power, there is a restriction on the installation site and the restriction of the lower support structure due to the arrangement structure of the solar cell module is restricted, There is no problem in the case of outdoor facilities, but in case of installing in a multi-family house that occupies a large number of houses, it is difficult to individually install in a household.

In addition, since the supporting structure for supporting the conventional solar cell module is often joined by welding, the main frames and the supporting frames for supporting the solar cell modules, the supporting columns for supporting the main frame to the ground are respectively welded once, There is a difficulty in adjusting the arrangement state when welding is completed.

Particularly, in the case of a fixed support structure supporting a large number of solar cell modules in a large amount, the arrangement angle is fixed, and there is a limitation in adjusting the arrangement angle of the solar cell module according to the change of the sun height according to the season change. There is still a problem that the electricity production efficiency is lowered.

In Korea, when we look at the southern altitude of each season considering the latitude (38 °), the summit altitude of the sun is about 52 °, the altitude is 75.5 °, and the winter solstice is 28.5 °.

However, since the conventional solar power generation apparatus is installed with a fixed angle toward the south-east, there is an urgent need to take measures to cope with a large variation in electricity production amount by season.

In addition, as the eco-friendly energy business becomes visible and attention is focused on photovoltaic power generation, facilities for large-capacity photovoltaic power generation are required. However, a photovoltaic power generation device having a rotating structure corresponding to the altitude angle or the azimuth angle of the sun is a large- There is a limit that requires a facility capable of stably supporting the module.

In addition, in order to rotate a large-sized solar cell module in accordance with the altitude angle or azimuth angle of the sun, a large-scale personnel must be input to rotate and fix the solar cell module.

And certain features shown in the drawings are to be enlarged or reduced or simplified for ease of explanation, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

FIG. 1 is a perspective view of a photovoltaic device 1000 according to a first embodiment of the present invention, FIG. 2 is a front view showing the photovoltaic device 1000 shown in FIG. 1 from the front, Is a partial perspective view showing the elevation angle control unit 130 of the solar power generation apparatus 1000 shown in FIG.

1 to 3, a photovoltaic apparatus 1000 according to a first embodiment of the present invention includes a plurality of support frames 100 for supporting a solar cell panel 10, A fixed frame 120 for supporting the altitude angular rotary shaft 110 so as to be spaced apart from the installation surface, and a control unit 120 for controlling the angle of rotation of the altitude angular rotary shaft 110 And a driving unit 140 coupled to the altitude adjusting unit 130 and the altitude adjusting unit 130 so as to drive the altitude adjusting unit 130.

According to the present invention, since a plurality of solar panels are arranged in the horizontal direction on the support frame 100 and a plurality of solar panels can be rotated at one time so as to correspond to the seasonal altitude or hourly altitude angle of the sun, And it is also possible to perform maintenance with a minimum number of persons in adjusting the elevation angle of the solar power generation apparatus.

For this purpose, when the user rotates the elevation angle control unit 130 using the driving unit 140, a plurality of the solar panels connected to the elevation angle shaft 110 are rotated at the same time, The angle of elevation of the photovoltaic device can be adjusted.

Further, the solar power generator is fixed on the installation surface to maintain the set azimuth angle, and the elevation angle is adjusted along the sun's movement path. Here, the installation surface may be a roof or a roof of a building, or a water surface of a river or a lake, and the installation surface is not limited thereto. It is needless to say that the number of solar battery panels can be selectively changed according to the scale of the installed photovoltaic devices.

The supporting frame 100 is coupled to the elevation angle shaft 110 to provide a function of supporting the solar cell panel. Further, the support frame 100 rotates in the vertical direction in conjunction with the rotation of the altitude angular rotary shaft 110 on the altitude angular rotation axis 110 to rotate the altitude angle of the solar cell panel corresponding to the altitude angle of the sun . Since the plurality of solar cell panels are disposed along the longitudinal direction of the altitude angular rotary shaft 110, the support frame 100 is provided in a number corresponding to the number of the solar cell panels.

The elevation angle rotary shaft 110 rotates by driving the elevation angle control unit 130 and provides a function to simultaneously rotate all the solar cell panels coupled on the elevation angle rotary shaft 110.

The stationary frame 120 provides a function of fixing the entire photovoltaic device on the installation surface and prevents the solar cell panel from interfering with the installation surface by rotating the altitude angle rotary shaft 110 So as to be spaced apart from the elevation angle rotary shaft 110 and the installation surface.

The altitude angle adjuster 130 is disposed at one end of the altitude angle axis 110 to rotate the altitude angle axis 110 and to set the altitude angle axis 110 Provides the ability to maintain elevation angle.

The driving unit 140 is coupled to the altitude angle adjusting unit 130 to adjust the altitude angle by rotating the driving unit 140 when the altitude angle shaft 110 needs to be rotated. The driving unit 140 uses a manual driving unit 140 that is held by both hands and rotates clockwise or counterclockwise by being coupled to the elevation angle control unit 130.

4 is a perspective view showing the elevation angle control unit 130 of the photovoltaic device shown in Fig.

4, the altitude angle adjuster 130 includes a first gear provided at one end of the altitude angular rotary shaft 110, a gear meshed with the first gear, A third gear integrally provided on the lower side of the second gear to rotate in cooperation with the second gear, and a fourth gear meshed with the third gear and having a stopper therein.

The first gear and the second gear are formed of bevel gears capable of changing the direction of transmission of rotational motion. Therefore, the first gear and the second gear are formed such that the imaginary lines of the rotation axes are orthogonal to each other, and the second gear and the third gear are simultaneously driven by the same rotation axis.

The fourth gear and the third gear are formed so that the imaginary lines of the rotation axis are orthogonal to each other. More preferably, the rotation axis of the first gear and the rotation axis of the fourth gear are arranged parallel to each other. The fourth gear is provided with a stopper arranged to be able to be elastically transferred along the longitudinal direction of the rotation axis of the fourth gear. The stopper will be described in detail later.

5 is a perspective view showing a modification of the elevation angle adjusting section of the photovoltaic apparatus shown in Fig.

Referring to FIG. 5, the altitude angle adjuster 130 'is located at an inner or central portion from both ends of the altitude angular rotary shaft 110'.

Therefore, the first gear is disposed on the altitude angular rotational shaft 110 ', and the altitude angular rotational axis 110' is formed to protrude along the longitudinal direction of the first gear.

In this case, the force generated when the rotational angle of the elevation angle shaft 110 'is applied by the altitude angle adjuster 130' is small. Also, it is prevented that the altitude angular rotational shaft 110 'is twisted due to the rotational force generated from the altitude angle adjuster 130', or excessive torque is applied to the altitude angular rotational shaft 110 'adjacent to the first gear There is an effect that can be done.

6 to 8 are reference views showing the operating states of the stopper and the stopper of the photovoltaic device shown in Fig.

6 to 8, the stopper is arranged to be able to be elastically transported along the axial direction on the rotation axis of the fourth gear, thereby providing a function of selectively interrupting the rotation of the fourth gear. Therefore, it is possible to prevent the altitude angular rotary shaft 110 from rotating and deviating from the set angle by the load or the external force of the solar cell panel after the altitude angle adjuster 130 is adjusted to the set angle.

The stopper includes a main body inserted into a sliding groove formed in the fourth gear and provided so as to be movable along the axial direction of the fourth gear, and a stopper protruding from an outer circumferential surface of the main body, An elastic member provided between the main body and the sliding groove to elastically support the main body; and an elastic member protruding in the axial direction from the end of the main body so that the main body is not pressed to the inside of the fourth gear And a protrusion member for restricting the rotation of the main body in a state that the main body is not rotated.

The main body is formed in a cylindrical shape and is arranged to be elastically transferred along the axial direction in the sliding groove. At this time, a coupling groove for selectively coupling the driving unit 140 is formed at the center of one end of the main body. Preferably, one end surface of the coupling groove is formed of at least a polygonal shape having a triangle or more, more preferably a hexagonal shape.

The wing member provides a function of transmitting a rotational force generated between the main body and the fourth gear, and the main body and the fourth gear interlock with each other through the wing member. For example, when one end surface of the main body is formed in a polygonal shape, it is also possible to transmit a rotational force between the main body and the fourth gear without the wing member.

The elastic member is disposed between the other end of the main body and the sliding groove. When the driving unit 140 is coupled to the coupling groove and is pressed in the axial direction, the elastic member is compressed. Conversely, The elastic member is restored to its original state when the pressing force is released from the engagement groove. The elastic member may be made of spring or synthetic rubber.

At least one protrusion member protrudes from the one end of the main body at the outer side of the coupling groove. When the driving unit 140 is coupled to the coupling groove to press the main body, the driving unit 140 rotates, Thereby preventing the main body from rotating when the pressing force is released.

Therefore, as shown in FIG. 7, when the pressing force is released from the driving unit 140 to the main body, the projection member restricts rotation of the main body, so that the solar cell panel can be maintained in a rotated state at a predetermined angle It is effective.

Fig. 9 is a reference view showing a modification of the stopper operating state of the photovoltaic device shown in Fig. 8. Fig.

Referring to FIG. 9, an automatic driving unit 140 'may be used as the stopper.

The driving unit 140 'is selectively coupled to the engagement groove in the fourth gear to automatically rotate the driving unit 140' clockwise or counterclockwise when rotation of the elevation angle shaft 110 is required Provides the ability to adjust to the set altitude angle.

When the automatic driving unit 140 'is used, the user can more easily and conveniently rotate the elevation angle shaft 110 at a desired elevation angle, and the user can also use the large- The altitude angle can be adjusted by season or time, which can save cost by maintenance and repair.

The first sprocket 231 is rotatable integrally with the altitude rotary shaft 210. When the second sprocket 232 rotates, the first sprocket 231 is interlocked and rotated by the chain 233, The elevation angle of the battery panel is rotated at a set angle.

It is preferable that the first sprocket 231 is larger in diameter than the second sprocket 232. When the user rotates the second sprocket 232 to rotate the first sprocket 231, There is an effect that the elevation angle of the solar power generation device of large capacity can be adjusted to a set angle.

Although not shown in the drawing, the second sprocket may be provided with a separate speed reducer (not shown).

The stopper 230 includes a main body 236a provided with a coupling groove 236e which can be moved along the axis of rotation of the second sprocket 232 to selectively engage with the driving unit 140, A wing member 236d that protrudes from the outer circumferential surface of the main body 236a and interferes with the rotational direction of the second sprocket 232 on the sliding groove 235 formed on the inner circumferential surface of the stopper 230, An elastic member 236c provided between the main body 236a and the main body 236a to elastically support the main body 236a and an elastic member 236b protruding in the axial direction from the end of the main body 236a, And a protrusion member 236d for restricting the rotation of the main body 236a in a state where it is not pressurized inside of the main body 236a.

Here, the driving unit 140 may use a passive type tool that rotates the altitude rotary shaft 210 to be coupled to the coupling groove 236e 6 when the altitude is to be adjusted, Or an automatic tool having an internal drive motor and rotated by an electric driving force may be used. This is the same as the description of the driving units 140 and 140 'in the first embodiment, and thus a detailed description thereof will be omitted.
