Abstract
The invention discloses a device capable of decreasing or eliminating return difference of a solar tracking transmission system, relates to improvement on a solar energy utilizing device, and mainly relates to utilization of an inverse damping tracking system to solve the return difference of mechanical transmission. The invention provides the device capable of decreasing or eliminating the return difference of a solar tracking transmission system with simple structure and easy processing and manufacturing, which comprises a tracking system for an azimuth angle on the bottom surface of a tank body; the tail end of the tracking system is provided with a worm and a worm wheel; and the worm is driven by a motor. The device has a structural key point that an output shaft of the worm wheel is provided with a damping device.
Description
Technical field:
The present invention relates to the improvement of helioplant; Relate generally to and utilize reverse damping to solve the mechanically operated return difference of tracking system.
Background technology:
The tracking system of existing solar concentrator owing to reasons such as the accuracy of manufacture, wearing and tearing, when influenced by extraneous wind-force etc., during follower reverse movement in the tracking system, has produced motion return difference (that is, follower breaks away from the driving wheel contact).Make system be difficult to follow the tracks of the sun accurately, reliably by design accuracy, especially heavy in section concentrator.The domestic main means that address this problem are to improve the machining accuracy of transmission at present, yet, this is a cost to increase considerably manufacturing cost beyond doubt, and can not fundamentally solve because the backlash return difference that system's service wear produces problem that the tracking accuracy of influence constantly descends.
The mechanical system of following the tracks of the sun generally is divided into two kinds of single shaft and double-axis trackings, and promptly the angle of pitch is followed the tracks of and the azimuth tracking.Because when the angle of pitch is followed the tracks of, because of the deadweight of its reflector element part has produced downward damping action, so wind carries the influence of the tracking accuracy of this direction very little in practice.And azimuthal tracking, because the uncertainty of wind direction and wind-force, the moment of torsion that produces when wind direction wind-force is consistent with the pursuit movement direction and during greater than motion bearings resistance (very little), because the gap that design, manufacturing, assembling produce, cause uncontrollable motion return difference under its effect, what especially reflect on the heliostat tracking system that tower type thermal generation is used is more outstanding.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides a kind of simple in structure, is easy to the device that can reduce or eliminate return difference of solar tracking transmission system of processing and fabricating.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes the azimuthal tracking system on the tank floor, and the end of tracking system is worm screw, worm gear, worm screw is then by motor-driven, and its structural feature is that the output shaft of worm gear is provided with damping unit.
Beneficial effect of the present invention:
The present invention can utilize the damping unit on the output shaft of worm gear to come balance wind moment etc.; In addition, the present invention is exactly that the output shaft of worm gear is provided with damping unit, and its member is few, and body is simple, is easy to make; Can reduce or eliminate the return difference that tracking system produces.
