In recent years, the development of alternative energy is urgently needed as the crisis caused by the depletion of fossil energy and the burden of greenhouse gas reduction under the Climate Change Convention become visible.

In addition, it is required to build its own power production facilities in remote islands and remote areas where transmission and distribution facilities are impossible.

Renewable energy industry to produce electric energy from solar and wind power is growing by 20 ~ 30% annually in the world, and is rapidly growing as a high-tech new industry in the 21st century along with IT and BT industries.

In the conventional solar light collecting device, a solar cell panel in which cells and cells are connected in series and in parallel as necessary is fixedly installed at an angle of approximately 35 ° toward the south facing direction. This is to produce the maximum power by making the angle of incidence of the solar light and the solar panel perpendicular to each other in a fixed state.

However, in the case of Korea, since the altitude of the sun in each season varies from about 12 ° to 58 °, there is a problem in that the efficiency of the investment is low compared to the investment cost due to the low power productivity when the solar panel is fixed.

First, as shown in Figures 1 to 4, the solar panel angle adjustment device according to the present invention is largely built on the concrete foundation (1), so as to adjust the inclination angle in the vertical direction corresponding to the change in the altitude of the sun. Azimuth angle adjuster 20 rotatably mounted on the upper end of the support 10, and a solar panel 30 is installed on the upper surface and the azimuth angle adjuster to adjust the inclination angle in left and right directions in response to changes in the orbit of the sun And a frame portion 40 rotatably mounted at 20, and a means for adjusting the left and right tilt angles of the frame portion.

In addition, the means for adjusting the left and right inclination angle of the frame part 40 is a pair of vertical links 51, one end of which is pin-coupled to both lower sides of the frame part 40 with the direction angle adjuster 20 therebetween. ) And a link member 50 formed of the other end of the vertical link 51 and a horizontal link 52 which is pin-coupled to both ends thereof, extending downwardly from the direction angle adjuster 20, and the end of which is a horizontal link ( 52 and a variable stand that is pin-coupled to the middle of the middle portion, and the one end is pin-coupled to the holder 60 and the other end is movable to move along the rail 53 installed on the horizontal link (52) (70) and the actuator is installed on the horizontal link 52 to adjust the inclination angle of the frame portion 40 by pushing and pulling the variable table 70, the piston 81 is the actuator pin-coupled to the variable table (70) 80 (see Fig. 2).

In the above technical configuration, the upper end of the support 10 is formed with a U-shaped groove, the direction angle adjuster 20 is fastened by a fastening member 11 made of a bolt and a nut in a state seated in the U-shaped groove. Accordingly, when the nut is loosened, the vertical angle of the solar panel may be adjusted in response to the change in the altitude of the sun, and the inclination angle may be fixed when the nut is tightened.

In addition, the frame part 40 is composed of a plurality of rungs 41 forming a right angle with the direction angle adjuster 20 and a rung 42 for binding the rungs 41 to one, the frame part 40 Protruding grooves 21 are formed in the direction angle controller 20 at regular intervals so as to easily rotate from side to side in the direction angle adjuster 20, and the crossbars 41 of the bar 41 correspond to the protrusion grooves 21. A projection 43 is formed on the bottom surface and the projection 43 is pin-coupled in a state embedded in the protruding groove 21 (see FIG. 3).

According to the above technical configuration, when the cylinder 81 is advanced by the operation of the actuator 80, the variable base 70 is moved outward along the rail 53 on the horizontal link 52, wherein the horizontal link ( Since the center 52 is pin-coupled by the holder 60, the horizontal link 52 is rotated. As a result, the vertical link 51 pin coupled to the front end of the horizontal link 52 is raised and the vertical link 51 pin coupled to the rear end of the horizontal link 52 is lowered to rotate the frame portion 40. (See Figure 4).

On the contrary, when the cylinder 81 is retracted by the operation of the actuator 80, the variable stage 70 moves inward along the rail 53 on the horizontal link 52, and the horizontal link 52 is fixed to the holder 60.

Rotate in one direction to reduce or increase the overall length of the wire (100, of course, by the attraction force, such as pulling the wire directly) to adjust the inclination angle of the direction angle adjuster 20. Then, when the inclination angle adjustment of the solar panel is completed, tighten the bolts of the fastening member 11 to fix the inclination angle of the solar panel and fasten the wire by hooking the hook installed in the ground fixed to the ground to firmly fix the inclination angle of the direction angle adjuster 20. .
