Sun Tracker with a Single Axis Angle Adjustable Solar Tracker

More particularly, the present invention relates to a solar short-axis tracker, and more particularly, to a solar short-axis tracker that rotates through a buffering force during rotation of a rotation shaft for rotating a sunlight frame, To an angle-adjustable solar short-circuit tracker.

Photovoltaic power generation is a power generation system that converts sunlight directly into electric power. Unlike existing energy sources, unlike pollution-free energy sources that do not cause greenhouse gas emission or environmental destruction, , And the related arts of the photovoltaic devices have been variously released.

A photovoltaic power generation apparatus includes a photovoltaic module in which sunlight is incident to produce a basic configuration of the photovoltaic power generation device, a modular frame for fixing a plurality of the photovoltaic modules on a surface thereof, a post for inclining the module frame, And a rotation axis for fixing the module frame to rotate with respect to the post so that the module frame can have a rotation angle about the rotation axis.

In addition, there has been proposed a tracking device that rotates the module frame relative to the post so that the sunlight can always be incident upon the movement of the sunlight. The module frame rotates along the direction of the sunlight while the sunlight is moving, .

As described above, many technologies have been proposed to enable incident light while tracking sunlight.

For example, Korean Patent No. 10-1202059 has proposed a short-axis variable photovoltaic power generation device.

The uniaxillary variable solar photovoltaic device according to claim 1, wherein the solar cell device comprises a solar cell plate that generates electricity by incident sunlight and is arranged in a longitudinal direction and is parallel to the solar cell device, An auxiliary frame arranged laterally parallel to each other; A main frame supporting a lower portion of the subframe and formed in parallel with the solar panel and forming a plane parallel to the solar panel; A main shaft rotatably mounted on the main frame, a main shaft rotatably mounted on the main frame, The support post supporting the rotation center shaft with a main bracket formed at an upper portion thereof and the lower portion being fixed to a ground or a structure; The main bracket being fixed to an upper end of the support post and holding the rotation center shaft; And fixing means for fixing the main frame and the rotary shaft combined body so as not to rotate when the solar battery board has a certain angle with the support post.

According to the present invention, when the altitude difference of the sun such as summer and winter is remarkable and it is necessary to adjust the angle (or elevation angle) of the solar panel toward the sun several times a year (for example, In order to adjust the angle of the solar panel manually. However, this is a problem that can not be easily controlled by the operator.

As another example, Korean Utility Model Registration No. 20-0453275, issued on April 22, 2011, discloses a tracker device for a variable power photovoltaic power generation system.

The connecting member includes: a connecting member provided at an upper end; a column body having a fixing base extended horizontally and installed vertically to the ground; a rotating shaft axially rotatably installed on the connecting member; A module frame configured to be installed immediately; A solar unit having a solar panel fixed between the installation bars and converting solar energy into electric energy, and a solar unit having a solar cell unit, And an angle adjusting member.

In this case, the angle of the module frame is adjusted by rotating the first angle-regulating member on the ground. Thus, it is difficult to adjust the angle and angle of the work by interlocking through the plurality of members.

As another example, Korean Patent Registration No. 10-1322965 discloses an apparatus for adjusting the angle of a solar collector plate.

This includes a solar condensing plate on which a plurality of solar cells are arranged; A fixed frame installed at a lower portion of the solar collector plate; A fixing plate provided at the rear center of the fixed frame; An angle regulating plate provided at a front center of the fixed frame and having a plurality of fixing grooves formed in a round portion formed at a lower portion thereof; A supporter having an upper portion inserted between the fixing plate and the angle adjusting plate and fixed by a hinge, A lifting and lowering means for lifting and lowering the lower portion of the base supporting portion, and a lifting and lowering means for selectively moving the upper and lower portions of the lifting and lowering means, respectively; And an angle adjusting means connected to the lower portion of the other side of the fixed frame and the lower portion of the supporting frame in an inclined manner to adjust the rotation angle of the fixed frame.

In such a case, there is a problem in that it is difficult to adjust the angle in the same way as well as an economic cost due to an increase in the number of parts.

In addition, Korean Patent Laid-Open No. 10-2010-0061271 discloses a solar tracking device.

This is a solar tracking device that rotates to improve the light collecting efficiency of solar light, comprising: a module frame having a plurality of modules for converting solar light energy into heat and / or electric energy; A module frame mounting shaft which is positioned below the module frame and joins the module frame and rotates itself about its center; A shaft supporting portion for supporting the module frame mounting shaft by engaging with the module frame mounting shaft in a coupling manner; A braggat formed to be able to insert a hinge on the bottom of the shaft portion; A base frame of a pyramid structure formed of at least three struts connected to the braggat by a hinge; Wherein the base frame is rigidly fixed by a ground and a fastening means so that the module frame mounting shaft rotates in the east-to-west direction every day, and is rotatable in the north-south direction by a hinge coupled to the bragget, Each of which is constituted by a separate manual driving device and / or an automatic driving device.

However, in the above case, when manually adjusting the angle of incidence of sunlight, it is difficult for one operator to change the angle of rotation in the field. In addition, in the case of automatic operation, economical cost is added, and it is easily damaged.
