Photovoltaic plate pitching angle manual adjusting and positioning mechanism

Abstract

The invention discloses a photovoltaic plate pitching angle manual adjusting and positioning mechanism which comprises a standing pillar, an angle adjusting mechanism and an angle positioning mechanism. The angle adjusting mechanism and the angle positioning mechanism are arranged above the standing pillar. The angle adjusting mechanism comprises an installation platform, a lifting screw rod, a standing bearing block, a driving rotation shaft, a speed reducer, a motor installed on the speed reducer, a pitching rotation shaft which is installed in the middle of the driving rotation shaft and perpendicular to the driving rotation shaft and a pitching bearing block which is fixedly installed on the backlight side of a photovoltaic plate installation frame. The angle positioning mechanism comprises a positioning dial and a positioning pointer. The photovoltaic plate pitching angle manual adjusting and positioning mechanism is simple in structure, convenient to machine, manufacture, use and operate and capable of driving the lifting screw to move by rotating a manual handle so as to change the pitching angle of the photovoltaic plate assembly. The positioning mechanism composed of the positioning indicator and the positioning dial is arranged on the pitching rotation shaft and the pitching bearing block and precision in adjustment by an operator is improved.

Description

technical field [0001] The invention relates to a power mechanism, in particular to a photovoltaic panel pitch angle manual adjustment and positioning mechanism. Background technique [0002] With the improvement of people's solar energy utilization efficiency, the use of high-precision omni-directional tracking sun track tracking devices is becoming more and more common; generally, omni-directional sun tracking requires at least two motors to drive separately in two-dimensional directions; especially For a tracking mechanism that simultaneously tracks the solar hour angle and the solar declination angle, at least one motor is required to track the solar hour angle, and the other motor is required to track the solar declination angle; but the variation range of the solar declination angle is Between ±23.5°, it only changes 0.26° every day. A separate motor is used to drive the tracking of the sun’s declination angle, which causes waste and increases the power consumption of ...

A separate motor is used to drive the tracking of the sun’s declination angle, which causes waste and increases the power consumption of the entire tracking device.
