ACCURATE INDEPENDENT 2-DOF SUN-TRACKING DEVICE

NºPublicación: US2023031272A1 02/02/2023

Solicitante:

KWAK BYUNG MAN [KR]
KWAK JOON YOUNG [KR]
KWAK KYUNG WOON [KR]

Resumen de: US2023031272A1

This disclosure relates to exact sun-tracking devices by the principle of exact sun-following by independent 2-DOF, which says if the daily rotation axis is installed on a ground structure in parallel with the earth's rotation axis and the elevation angle axis is mounted perpendicularly to the daily rotation axis then the two rotational degrees of freedom are independent of each other. This property makes a separate intermittent control with a forward half-step setting very efficient and energy-saving. A control system by a wire loop driving mechanism has several advantages, holding the structure securely, relieving a motor weight from the over-structure, and allowing a simple economic control with self-locking. Three structural types are categorized: a long shaft type, a tip-tilt type, and a tension structure type. An array sun-tracking device with an efficient wire loop actuating mechanism illustrates a preferred sun power generation system for general and industrial applications.
