Solar panel tilt device

Abstract

To provide a solar panel tilting device capable of withstanding strong winds such as typhoons and changing the direction of a solar panel. [Solution] A solar panel tilting device that tilts a solar panel 1 around a central shaft using a chain drive from a motor 11 with a reducer to track the sun. In the solar panel tilting device, the solar panel 1 is mounted on a solar panel mounting plate 2, and a central shaft fixing block 4 is attached below the solar panel mounting plate 2, with a central shaft inserted into the central shaft fixing block 4, causing the solar panel 1 to rotate and move around the central shaft. The fixing block 4 is fixed to the ground by a support 5 for fixing the central shaft.

Description

[Technical field]

[0001] [Background technology]

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

[0003] [Patent Document 1] Patent Publication 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 issues such as snow accumulation, so 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 designed to withstand strong winds such as those caused by typhoons and storms, and these can be avoided by changing the direction of the solar panels. Effect of the Invention

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

[0008] [Figure 1] External view A solar panel 1 is installed on a solar panel mounting plate 2. A central shaft fixing block 4 is attached under the solar panel mounting plate 2, and the central shaft is inserted in the central shaft fixing block 4, and the solar panel 1 rotates around the central shaft. The central shaft fixing block 4 is fixed to the ground by a central shaft fixing support 5. A chain mounting guide plate 13 is attached to the solar panel mounting plate 2, and the chain is attached to this chain mounting guide plate 13 (which is semicircular in shape) so that it follows the outer circumference, and is set in the chain fixing block 6 via three sprockets 9. The sprocket 9 is fixed by sprocket support supports 14 and 15, and the chain fixing block 6 has a chain slack adjustment function. The motor 11, which has a motor 11 and an electromagnetic brake 12 attached to the reducer 10, is driven by the motor 11, which rotates the sprocket 9, and the solar panel can be tilted around the central shaft 3 via the chain 7. The reducer is about 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 the solar panel 1 is tilted under the control of a timer.

[0009] [Diagram 2] Diagram of tilted solar panel This diagram shows how the drive shaft 8 rotates, which in turn rotates the sprocket 9, driving the chain and tilting the solar panel.

[0010] [Diagram 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 prevents the solar panel mounting plate 2 from tilting any further when activated. 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 for showing how efficiency increases when solar panels are installed at an angle depending on the installation location. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Switch 18 is used as the starting point to rotate the motor via a computer, and the solar panel 1 is tilted and controlled by a timer, with the program changed according to the season. The R dimension in drawing 1 is important, and without precision, smooth movement will be impossible. It is necessary to periodically 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 designed to withstand strong winds such as typhoons, and can avoid snow accumulation, It has potential industrial applications. [Explanation of symbols]
