Single-stand-column double-shaft solar tracking device

Abstract

The invention discloses a single-stand-column double-shaft solar tracking device. The single-stand-column double-shaft solar tracking device comprises a base, a stand column, an adjustment rod, a first cross beam, a lug plate, a first hinge pin, a hinge support, a second hinge pin, a solar panel, a longitudinal beam, a pulley block, a second cross beam, a vertical arm, a cross arm, a main beam, a pulling spring, a steel wire rope, a limit switch, a limit block, a first bearing, a speed reducer, a second bearing, a first support, a bearing seat, a second support, driving shafts, pulleys and a fastening bolt. According to the single-stand-column double-shaft solar tracking device, the large transmission ratio is achieved by the adoption of the pulley system at a low cost, driving of the steel wire rope and automatic tracking of the solar azimuth are achieved by the adoption of the two main driving shafts, control over the tension of the steel wire rope is achieved by means of the pulling spring, overload protection of a system is achieved at a low cost according to the characteristic that the friction force between the steel wire rope and the driving shafts are limited, and strong wind can be sensed and avoided by the adoption of the limit block and the limit switch at a low cost. Manual tracking of the solar zenith angle which changes slowly is achieved by adjusting the adjustment rod manually at a low cost.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a solar tracking device suitable for solar cells. Background technique [0002] Solar cells have the ability to directly convert sunlight into electricity. In order to allow solar panels to receive the most sunlight, the light-absorbing surface of the battery should always be perpendicular to the direction of solar radiation where it is located. Therefore, the tracking solar panel bracket should slowly rotate with the sun . Due to the slow rotation and the large transmission ratio of the drive system, the existing design generally adopts the joint drive of the gearbox and the electric push rod or worm gear. The disadvantage is that the cost is high and it is difficult to popularize; The cost of the device is the research direction of the solar tracking device for photovoltaic power generation. Contents of the invention [0003] The technical problem to be solved...
