Novel chain-transmission solar two-dimensional tracking device

Abstract

The invention provides a novel chain-transmission solar two-dimensional tracking device. An azimuth rotating mechanism, a pitching support, a pitching mechanism, a battery component bracket and a solar battery component are arranged sequentially from bottom to top; a photosensitive sensor and a wind speed sensor are arranged on the solar battery component bracket; the pitching support is fixed above an azimuth rotating vertical shaft and used for supporting the solar battery component bracket; the pitching mechanism is fixed above the pitching support; in the azimuth rotating mechanism and the pitching mechanism, a motor drives chain wheel transmission by a worm wheel, a worm, a main shaft which is connected with the worm wheel, and a key so as to drive a chain to rotate; and the chain is fixed on the azimuth rotating vertical shaft and a chain transmission bracket, so the azimuth rotating vertical shaft and the chain transmission bracket rotate, and the tracking of a solar azimuth angle and an elevation angle is realized. The novel chain-transmission solar two-dimensional tracking device has the advantages of simple structure, high tracking accuracy, low manufacturing cost, low energy consumption, high cost performance, automatic tracking capability and wind-sheltering capability.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a two-dimensional chain-driven solar tracking device capable of maintaining an optimal incident angle with the sun at all times, automatically and slowly tracking the sun's azimuth, and having low manufacturing costs. Background technique [0002] With the development of solar energy application technology, people pay more and more attention to improving the capacity and operational reliability of photovoltaic power generation, reducing investment costs and maintenance costs. How to improve the ability of photovoltaic power generation is generally: firstly, improve the photoelectric conversion efficiency of solar cell components; secondly, use automatic tracking technology to make the light-receiving surface of solar cell components always align with the sun. In addition, the power generation capacity of the solar cell module is proportional to the intensity of the sunlight ...

AI Technical Summary

Problems solved by technology

During the tracking process, the gear drives the power generation device to rotate. Due to the small diameter of the gear itself, in order to ensure the strength of the gear teeth, the modulus of the gear must be increased, which virtually makes the reduction box too heavy

At the same time, due to the high manufacturing cost of the gears, it is difficult to eliminate the backlash, and it is easy to generate impact between the gears during operation or under the action of the wind, resulting in premature failure of the gears
