Patent ID: 7989746

Claim:
A rail-type solar tracking system with a focusing function, comprising: a plurality of support elements for supporting a periphery of a Fresnel lens; a rail platform disposed under the Fresnel lens, and having a first rail installed separately on both sides of the rail platform; a load bearing platform disposed between the first rails, the load bearing platform being movable along the first rails and having a solar cell and a plurality of sensors carried thereon, the solar cell being provided for collecting a solar energy and converting the solar energy into an electric energy, the sensors being provided for detecting a focus position of sunlight after the sunlight is passed through the Fresnel lens; a pushing device for pushing the load bearing platform to displace the solar cell on the loading bearing platform to the focus position, wherein the pushing device includes a U-shaped mechanical structure having a second track disposed perpendicularly on each side of the U-shaped mechanical structure, the load bearing platform being disposed between the second tracks without being restrained by the second tracks; and a first motor, for pushing the U-shaped mechanical structure to move along a track direction of the first rail, so as to move the load bearing platform on the rail platform along the first rail.
