Description

[Technical Field]

[0001] [Background technology]

[0002] Currently, most solar panels in use are fixed and have poor power generation efficiency. There are few devices that allow solar panels to move in accordance with the movement of the sun, and few that are inexpensive to install and have a structure that can withstand strong winds.

[0003] [Patent Document 1] Patent Publication No. 2011-243934 [Patent Document 2] Patent 7433691 [Patent Document 3] Mito 3207547 Summary of the Invention [Problem to be solved by the invention]

[0005] Currently, most solar panels in use are fixed type, and in snowy regions, they have poor power generation efficiency due to problems such as snow accumulation, and the solar panels are not being used to their full potential. [Means for solving the problem]

[0006] The chain-driven device that tilts the solar panels is sturdy, so the solar panels can be tilted and moved toward the sun, increasing power generation efficiency. In snowy regions, the problem of snow accumulation can be avoided by tilting the solar panels almost vertically. The structure is able to withstand strong winds such as those caused by typhoons and strong winds, and these can be avoided by changing the direction of the solar panels. [Effects of the Invention]

[0007] By tilting the solar panels toward the sun, power generation efficiency increases, and the simple structure for tilting the solar panels makes it practical. [Brief explanation of the drawings]

[0008] [Figure 1] External view: Solar panel 1 is mounted on solar panel mounting plate 2. Central shaft fixing block 4 is attached below solar panel mounting plate 2, and the central shaft is inserted into central shaft fixing block 4, around which solar panel 1 rotates. Central shaft fixing block 4 is fixed to the ground with central shaft fixing support 5. Chain mounting guide plate 13 is attached to solar panel mounting plate 2. The chain is attached to this semicircular chain mounting guide plate 13 along its outer periphery, passing through three sprockets 9 and set in chain fixing block 6. Sprocket 9 is fixed with sprocket support supports 14 and 15. Chain fixing block 6 has a chain slack adjustment function. Motor 11, which is connected to reducer 10 and has an electromagnetic brake 12, drives motor 11. Rotating sprocket 9 via chain 7 allows the solar panel to tilt around central shaft 3. The reducer has a rotational speed of approximately 1:400, and the electromagnetic brake is also used during strong winds and typhoons. The motor is rotated by a computer using switch 18 in the switch storage box as the starting point, and solar panel 1 is tilted and used under the control of a timer.

[0009] [Figure 2] Diagram of tilted solar panel This diagram shows how the solar panel tilts as the drive shaft 8 rotates, causing the sprocket 9 to rotate and drive the chain.

[0010] [Figure 3]Switch storage box A switch mounting plate 17 is attached to the central shaft 3, and a switch 18 is attached to the switch mounting plate 17. A switch storage box 16 is attached to the solar panel mounting plate 2, and a switch piece 20 is attached to part 19 of the switch storage box with a switch piece mounting bolt 21. When the solar panel mounting plate 2 moves, the switch piece 20 can activate the switch 18. The switch 18 is a preventive switch that, when activated, prevents the solar panel mounting plate 2 from tilting any further. A motor is turned by a computer using the switch 18 as a starting point, and the solar panel 1 is tilted using a timer.

[0011] [Figure 4] Diagram of solar panel installation at an angle This is a reference diagram showing how efficiency increases when solar panels are installed at an angle depending on the location. DETAILED DESCRIPTION OF THE INVENTION

[0012] The motor is turned by a computer using switch 18 as the starting point, and the solar panel 1 is tilted and used under the control of a timer, with the program changed according to the season. The R dimension in Drawing 1 is important, and if it is not accurate, smooth movement will be impossible. It is necessary to regularly check the chain for slack. [Industrial Applicability]

[0013] Although the installation costs are high, the solar panels track the sun and are therefore efficient. The structure is resistant to strong winds such as typhoons, and can avoid snow accumulation, It has potential industrial applicability. [Explanation of symbols]
