Pitch angle regulating mechanism of solar tracking device based on rotation of earth

Abstract

The invention discloses a pitch angle regulating mechanism of a solar tracking device based on rotation of the earth. The pitch angle regulating mechanism comprises a working platform. A slide rail device is rotationally installed in the middle of the working platform through a stand column, and a solar panel is fixedly arranged on the upper side of the slide rail device. A sliding rod is arranged in a slide groove of the slide rail device, one end of the sliding rod is fixedly installed on the upper side of a lead screw, the lead screw is connected with an output shaft of a worm and gear speed reducer through a synchronizing shaft, and an input shaft of the worm and gear speed reducer is connected with a first output shaft of a motor. The working platform is fixedly installed on a main shaft, the main shaft is rotationally installed on two supporting columns arranged in parallel, a worm gear is fixedly arranged at one end of the main shaft, and a worm meshed with the worm gear is connected with a second output shaft of the motor. The pitch angle regulating mechanism has the advantages of being reasonable in design, capable of regulating the pitch angle of the solar panel, high in automation degree because of the mechanical and electrical integration design, simple and compact in structure and convenient to disassemble, assemble, carry and maintain.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and relates to an angle adjustment mechanism, in particular to a pitch angle adjustment mechanism of a sun tracking device based on the rotation of the earth. Background technique [0002] Solar installations generally have the best orientation when the light is perpendicular to the solar panel, so this is also the core problem that must be solved for the efficient use of the sun. Since the position of the sun is constantly changing, the receiving surface must also be constantly oriented to the best position, so the sun's orientation must be realized. track. The solar trajectory can be regarded as the change of the real-time sun angle caused by the earth's rotation during the day, and the change of the sun's declination angle due to the earth's revolution in a year, and the change range of the declination angle is small. In the prior art, the design of the simultaneous trac...

Problems solved by technology

In the existing technology, the system design for simultaneous tracking in these two directions cannot be well considered. Either the design structure is complicated and it is not easy to popularize and apply; or there are many errors and high personnel costs.
