Description

Solar tracker for solar panels {SOLAR TRACKER FOR SOLAR PANEL}

The present invention relates to a solar tracking device for solar panels, and more specifically, to a solar tracking device for solar panels that tilts the solar panel according to the position of the sun so that sunlight is effectively concentrated on the solar panel.

In general, the solar energy collection efficiency of a solar panel is highest when the angle between the normal line of the solar panel and the direction of sunlight matches. In other words, in order to maximize the light collection efficiency of a solar panel, the angle at which sunlight is incident must be perpendicular to the surface of the solar panel.

Therefore, in order to secure sufficient energy from sunlight, solar panels must move according to the orbital displacement following the rotation and revolution of the sun and the Earth.

For this reason, most solar panels move automatically according to the movement of the sun to increase the efficiency of collecting sunlight.

This solar tracking system is a device that measures the altitude or azimuth of the sun or adjusts the altitude and azimuth angles so that the solar panel of a solar collector or solar power generation device tracks the sun according to a pre-programmed method according to time. .

The solar tracking device has a rotating joint that changes the direction of the frame on which the solar panel is installed. Typically, these rotating joints are composed of various forms such as axes and joints.

However, because the conventional rotary joint is formed to have a high height, the length from the rotation center of the rotary joint to the solar collector is long. Therefore, when the rotary joint unit operates, a large torque is generated in the rotary joint unit, and because of this, there is a problem in that the durability of the rotary joint unit is reduced.

In the case where the second additional power supply unit 450 is further provided, when the support frame 710a makes the fourth rotation (R4) and the one end 715a stops in a downward state, that is, in an inclined state, the third power supply is provided. Since the providing part 850 can support one end 715a of the support frame 710a, the second additional power providing part 450 is consumed to maintain the second shaft 400 in a fixed state. It has the effect of reducing power.

Likewise, the fourth power supply unit 860 may further provide a repulsive force to resist the third rotation (R3) when the support frame (710a) rotates (R3).

That is, when the support frame 710a makes a third rotation (R3) about the second central axis (B2) and the other end 716a of the support frame 710a rotates downward, the fourth power supply unit 860 Compressive force is applied. Then, the fourth power supply unit 860 can further generate and provide a repulsive force to resist the third rotation (R3).

Through this, it is possible to prevent the support frame 710a from suddenly starting the third rotation (R3) or from suddenly stopping the support frame (710a) in the third rotation (R3). In addition, since hunting due to self-weight and inertia is prevented during rotation and smooth rotation is possible, more precise control may be possible and the support frame 710a may be helped to stably perform the third rotation (R3).

Likewise, when the second additional power supply unit 450 is further provided, and the support frame 710a makes the third rotation (R3) and the other end portion 716a stops in the downward state, that is, in the tilted state, the fourth additional power supply unit 450 is further provided. Since the power provider 860 can support the other end 716a of the support frame 710a, the second additional power provider 450 is used to maintain the second shaft 400 in a fixed state. It has the effect of reducing the power used.

The first, second, third, and fourth power supply units 810, 820, 850, and 860 may all be the same. Therefore, as shown in FIG. 5, the third power supply unit 850 and the fourth power supply unit 860 may be formed alone or may be provided together with a compression spring.

Meanwhile, a plurality of support frames 710 may be provided and may be arranged to be spaced apart along the longitudinal direction of the second shaft 400 (see FIG. 1).

For convenience, taking the leftmost support frame 710a as an example when referring to FIG. 8, the support frame 710a may have a vertical plate 711a and a horizontal plate 712a. That is, the support frame 710a can be bent, and through this, its rigidity can be increased. This may be the same for both the central support frame 710b and the right support frame 710c.

The vertical plates 712a, 712b, and 712c of the support frames (710a, 710b, and 710c) may be coupled to the upper part of the second shaft 400, and through this, the support frames (710a, 710b, and 710c) may be connected to the second shaft. It can be tilted by rotating around the second central axis (B2) integrally with (400).

As shown again in FIGS. 8 and 9, coupling grooves 713a and 713b may be formed at the lower ends of the vertical plates 712a, 712b, and 712c of the support frames 710a, 710b, and 710c, respectively (vertical plates ( A coupling groove is also formed in 712c), but not shown). In addition, the second shaft 400 may be inserted and coupled to each coupling groove (713a, 713b).

Through this, the height of the vertical plates (712a, 712b, 712c) is increased to increase rigidity, and the separation distance (H2) between the upper ends of the support frames (710a, 710b, 710c) and the central axis of the first shaft 200 ) can be reduced.

Additionally, a collision avoidance groove 714 may be formed in the support frame 710b provided on the upper side of the support flange 120 among the support frames 710a, 710b, and 710c. The collision avoidance groove 714 may be formed so that the support flange 120 is inserted when the support frame 710b rotates about the second central axis B2. When the support frame 710b rotates around the second central axis B2 and the support flange 120 is inserted into the collision avoidance groove 714 when the support flange 120 is tilted, a collision between the support frame 710b and the support flange 120 occurs. It can be prevented. Therefore, tilting by rotation of the support frame 710b can be performed stably.

In particular, when the upper part of the support flange 120 is inserted into the collision avoidance groove 714, the height of the support frame 710b can be lowered. That is, each support frame (710a, 710b, 710c) must have an upper surface of the same height. If there is no collision avoidance groove 714, a collision with the rotating body support flange 120 of the central support frame 710b may occur. To prevent this, the height of the central support frame 710b must be increased. Then, because the heights of all the support frames 710a, 710b, and 710c are increased, the vertical distance from the first shaft 200 to the solar panel increases as a result. Then, when the solar panel installation frame 700 rotates, a large torque is generated in the parts related to the driving of the first shaft 200, including the first shaft 200, and accordingly, the first shaft 200 and other The durability of parts related to driving the first shaft 200 may be reduced.

However, as in the present invention, when the coupling grooves 713a and 713b and the collision avoidance groove 714 are formed, the installation height of the central support frame 710b can be lowered, and through this, all support frames 710a and 710b Since the installation height of 710c) can be further lowered, the distance H2 between the upper ends of the support frames 710a, 710b, and 710c and the center of the first shaft 200 can be lowered.

Then, as a result, the vertical distance from the first shaft 200 to the solar panel is reduced. Therefore, when the solar panel installation frame 700 rotates, torque may be reduced in parts related to driving the first shaft 200, including the first shaft 200, and through this, the first shaft 200 Fatigue of parts related to driving of the first shaft 200, including, can be reduced and durability can be improved.

Meanwhile, as shown in FIGS. 1, 4, and 6, the solar power tracking device for solar panels may further include a control unit 480.

The control unit 480 includes a first power provider 810, a second power provider 820, a third power provider 850, a fourth power provider 860, and a first additional power provider 250. and the second additional power supply unit 450, so that these power supply units (810, 820, 850, 860, 250, 450) can be organically controlled. Through this, the control unit 480 can control the tilting of the solar panel installation frame 700 so that the solar panel 10 accurately tracks sunlight.
