Automatically tracking device for elevation rotating shaft fixed solar receiver

Abstract

The invention relates to an automatic tracking device for an elevation rotary shaft to fix a solar receiver. The base body (1) of a bracket (4) is supported by a latitude adjustment mechanism; the bracket (4) is provided with a fixed azimuth shaft (12); a box body (20) on the azimuth shaft (12) is provided with an elevation rotary shaft (16) vertical to the azimuth shaft; an optical receiver is linked with the elevation rotary shaft; the box body is provided with an azimuth motor (7), an azimuth drive mechanism, an elevation motor (13) and an elevation drive mechanism; the optical receiver is provided with two light-collecting bases (22, 23) respectively with a light-collecting window; the front end surface of either light-collecting base is provided with a groove (22a, 23a); one side of the groove (22a, 23a) and the collecting surface of the optical receiver are oblique; two oblique sides of the light-collecting bases are opposite in the slanting directions; the slope bottom of the oblique bottom of either groove is respectively provided with a photosensitive element (24,25). The tracking device is controlled by an electronic control device; thus the optical receiver is guaranteed to be always dead against the sun; the tracking device has a reasonable and reliable structure and accurate tracking; moreover, the tracking device can track other light sources.

Description

technical field [0001] The invention relates to a tracking device, in particular to an automatic tracking device for a solar receiver with an elevation-angle rotating shaft fixed and capable of tracking a light source. Background technique [0002] When solar collectors are used to collect solar energy, the relative movement of the earth and the sun will cause the sunlight to irradiate the solar collectors obliquely, resulting in low collection efficiency. In order to ensure that the solar collectors can always face the sun, some tracking methods are currently used The device is used to drive the solar collector to follow the sun to realize synchronous tracking of the sun. An existing ideal tracking device can realize synchronous tracking in azimuth and elevation, but the problem is that the structure is relatively complicated and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a simple and reasonable sync...

In order to ensure that the solar collectors can always face the sun, some tracking methods are currently used Device to drive the solar collector to follow the sun to achieve synchronous tracking of the sun

An existing ideal tracking device can realize synchronous tracking in both azimuth and elevation, but the problem is that the structure is more complicated and the production cost is high
