Large type wind proof light collecting device with capability of automatic tracking sun

Abstract

A large wind-proof daylight collector able to automatically track sun is composed of a daylight gathering module array, supporting frame, azimuth and altitude angle driver, a tracking controller, andazimuth and altitude angle sensors for sending the signals to the tracking controller. Its advantages are simple structure and wind-proof performance and high tracking precision.

Description

technical field [0001] The invention relates to an automatic tracking solar lighting device, in particular to a large-scale windproof automatic tracking solar lighting device, which belongs to the technical field of solar energy utilization. Background technique [0002] Entering the 21st century, human beings are faced with severe challenges to energy development from "population, resources, and the environment". Under the dual pressure of energy conservation and environmental protection, both developed and developing countries are developing and utilizing renewable resources. Renewable energy is one of the important strategic decisions for sustainable development. Solar energy is a kind of green and non-polluting renewable energy, which is inexhaustible and inexhaustible. It can be predicted that solar energy will become the leading role in the energy field in the near future. At present, various solar energy utilization technologies are one of the fastest growing technol...

Problems solved by technology

However, for large-scale or super-large solar energy collection and utilization devices, since the weight of the huge concentrating module array is only borne by a column, the supporting frame is prone to deformation and the driving is difficult; and because the radius of rotation is too large, even if the A small error at the central axis of azimuth or elevation will be greatly magnified at a position away from the center, so it is difficult to achieve accurate tracking of all concentrating modules; a large array of concentrating modules is like an open sail , strong torsion will be generated under strong winds, and the mechanical transmission mechanism may be damaged because the array of light-concentrating modules only rotates around one shaft

The U.S. patent "Two-axis tracking solar collectormechanism" with the patent number US5169466 proposes a large-scale automatic tracking solar collectormechanism, which includes a two-axis tracking mechanism, a lightweight support frame and an array of concentrating modules composed of Fresnel lenses , the two-axis tracking mechanism drives several driven worm and gear mechanisms to adjust the azimuth and elevation angles of the light-concentrating module array through two sets of active worm and worm mechanisms. The two-axis tracking mechanism is too complicated, the processing cost is expensive, and the installation accuracy is high, so it is difficult to popularize and apply
