Abstract

The invention aims to provide a single axis tracking device for photovoltaic power generation. The single axis tracking device for photovoltaic power generation comprises a power generation unit, a driving device and a transmission mechanism, wherein the power generation unit comprises a carrier mounting a photovoltaic assembly and a bracket for supporting the carrier, and the carrier rotates along the directions of west and east on the bracket; the transmission mechanism comprises a driving wheel, a driven wheel, a pulley and a driving rope, wherein the driving rope is used for winding the driving wheel and the pulley and is connected at two different parts along circumferential direction of the driven wheel, so as to enable the driving rope to transmit between the driving wheel and the driven wheel; and the driven wheel is arranged on the carrier of the power generation unit and can drive the carrier of the power generation unit.

Description

technical field [0001] The present invention relates to solar tracking devices. Background technique [0002] U.S. Patent No. 6,058,930 discloses a push rod type tracking device with at least one north-south torsion tube to support a solar panel array, wherein at least one support on the ground has a pivot element connected to the journal of the torsion tube to drive The device has a body portion, mounted on a foot, with a link coupled to a torque arm on a torque tube constructed in two or more sections with one section molded to the end of the next section for a tight fit, The driver can be used to drive multiple rows of solar panels. The drive of such a pusher type tracking device has a dead angle, so the maximum tracking rotation range is limited. Contents of the invention [0003] The purpose of the present invention is to provide a single-axis tracking device for photovoltaic power generation. [0004] The single-axis tracking device for photovoltaic power generati...
