Description
[technical field]
The present invention belongs to field of solar energy on broad sense, in this solar tracking system field of refering in particular to photovoltaic battery panel and focusing type solar heat collector, especially refer to the field of pole axis solar tracking system.
[background technology]
The present invention is meant solar collector, especially refers to the pole axis tracking system device, follows the tracks of the motion of the sun with respect to the earth, thereby makes collection solar energy reach higher efficient and lower cost.The present invention is applied to dull and stereotyped photovoltaic panel and focuses on photo-thermal or photovoltaic devices.
The photovoltaic solar cell plate is widely used on the Application of Solar Energy of dwelling house or commerce.Because the motion of the relative earth of the sun, the sunshine that causes shining on the fixing photovoltaic battery panel has different incidence angles in the different moment or annual different time every day.This kind incident ray can reduce the collection efficiency of solar panel and reduce the electric weight that this solar panel produces.Because the solar energy of collecting is directly proportional with cosine angle, i.e. angle between the vertical surface of the incidence angle of sunshine and solar panel, the loss that this effect caused is the cosine losses of knowing.For improving the collection efficiency of sunshine, solar panel can use a tracker to make it keep approaching vertical position with sun incident light.
Tracker can be widely used on the focusing solar panels, by large-area optical collector with solar light focusing on a small size solar collector, this solar collector can be photovoltaic cell or photothermal converter.For focus is remained on the target receiver, this tracking system will be followed solar motion, to keep focusing.
The two-dimensional tracking system has two kinds of forms, i.e. azimuth/height tracing and polar angle/season (or equator) tracking (with reference to " from the energy of the sun " chapter 4, http://www.powerfromthesun.net).For azimuth/height tracing system; its mechanical realization is comparatively simple; but; because the required rotary speed of diaxon is not invariable and interdepends; therefore need frequent adjustment in any given place; and to follow the tracks of the control scheme reliably be complicated and difficult, also needs induction and control initiatively usually.For polar angle/season angle (or equator) tracking system, its two is separate.Rotary speed around pole axis is fixed, and is approximately per hour 15 degree in the daytime.Yet its in season the angle rotation very slowly and move the season that is easy to follow the tracks of the sun.But the mechanical conceptual of realizing this kind tracking system no all roses.In many previous patents of invention this system all there is description, comprises United States Patent (USP) 4,285,567 and United States Patent (USP) 4,413,423 and United States Patent (USP) 6,284,968B1.In all systems formerly, the main body of solar collector can apply a bigger moment of torsion to pole axis, and need rotate with fixing speed at day spaced winding pole axis.So, can increase the loading demand of motor and under high wind load situation, cause the unstability of system.The present invention is exactly in order to improve this problem.
Tracking system all needs motor usually and drives control element for each tracker.In order to reduce the cost of system, wish very much with a motor and drive control to drive several trackers simultaneously.Previous patent US6,058,930 tracking system of having set forth by an one dimension realizes this imagination.In this invention, Linear actuator must change its angle in tracing process, make pursuit movement become irregular thus, needs detection and control initiatively.Than the long very heaviness that is rigidly connected also, its height changes when tracking always simultaneously, can make that like this system is unreliable between the tracker.The present invention has disclosed a very simple pole axis tracking system design, has eliminated its weak point.The present invention is applicable to the tracking system of a peacekeeping bidimensional.
[summary of the invention]
The purpose of this patent is exactly for a kind of solar energy tracking design is provided, to avoid above-mentioned shortcoming.A special purpose of the present invention provides mechanical conceptual, can make to be applied to moment minimum on the rotating shaft, thereby can increase the stability of system.Another special purpose of the present invention provides a design, by one group of motor/worm-gear toothing and control system, drives a plurality of systems with simple gear/chain device.

For light harvesting type gatherer, can adopt the two-dimensional tracking device.In these examples, increased another perpendicular to first spool second season rotating shaft.The second rotating shaft pivot supports (having bearing) and is fixed on first rotating shaft, and this panel is fixed on the rotating shaft in season.For reducing or eliminating the huge torsion that acts on the rotation pole axis, collector panel is separated from the centre, and so, this panel can pass from pole axis when axle rotates along season.Season, shaft support part and the panel that is provided with like this made that panel is zero to the torsion of pole axis substantially.Second is rotated at a slow speed to follow the tracks of the motion in season in the sun 1 year.For the two-dimensional tracking device, the pole axis of a large-scale tracker cohort can be by single motor-driven, and the axle in season of each tracker then will drive by the independent motor/gear on worm that is installed on the tracker.The control system of tracker can be programmed to " date logicality (chronologically) ", with according to clock that the panel location is vertical with the sun all the time.Clock time can obtain by gps signal or battery-driven electronic clock accurately.
