Title:
FLEXIBLE DRIVING DEVICE FOR ALL-TERRAIN-MATCHING LINKAGE TRACKING PHOTOVOLTAIC SUPPORT
Document Type and Number:
WIPO Patent Application WO/2017/197966
Kind Code:
A1
Abstract:
Provided in the present invention is a flexible driving device for an all-terrain-matching linkage tracking photovoltaic support, comprising: a reducer sprocket, columns for supporting and rotating solar panels, and main beams that are movable on the columns. The main beams are provided thereon with purlins for transferring power to respective arrays of solar panels, the rear end of a preceding purlin being connected, by means of a synchronous cable guided by a pulley A, to the front end of a following purlin, realizing a head-to-tail serial connection of the purlins. The reducer sprocket drives a transmission chain in a reciprocating motion, two traction cables being respectively connected to the two ends of the transmission chain, and the other end of the two traction cables being connected to synchronous cables via two pulleys B. The two pulleys B each are fitted with a counterweight to maintain an automatically compensated tensile force of the transmission chain and the traction cables. The present invention is structurally simple and easy to install, solving the problem that a linkage horizontal single-axis, linkage inclined single-axis, or linkage array-type double-axis tracking support has to meet a high standard concerning the flatness of the land and cannot be installed and used on a barren mountain or a steep slope with complex terrain.
