Automatically tracking device for direction rotating shaft fixed solar receiver

Abstract

The invention relates to an automatic tracking device for an azimuth rotary shaft to fix a solar receiver. A bracket (2) supported by a base body (1) is provided with an elevation shaft (11); a box body (3) on the elevation shaft is provided with an azimuth rotary shaft (7) vertical to the elevation shaft; an optical receiver (4) is linked with the azimuth rotary shaft; the box body is provided with an azimuth motor (8), an azimuth drive mechanism, an elevation motor (13) and an elevation drive mechanism; the optical receiver is provided with two light-collecting bases (5, 15) respectively with a light-collecting window; the upper surfaces of the two light-collecting bases are respectively provided with a groove (5a, 15a); the grooves respectively have an oblique surface; the light-collecting surface of the optical receiver is oblique; the two oblique surfaces of the two grooves are opposite in the slanting directions; the bottoms of the oblique surfaces of either groove are respectively provided with a photosensitive element (6,16). 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 a sun tracking device for a solar receiver. Background technique [0002] When using solar collectors 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 there are problems such as complex structure, high manufacturing cost, high tracking energy consumption, and low reliability. Contents of the invention [0003] The object of the present invention is to provide an automatic tracking device for a solar receiver with a fixed azimuth rotating shaft and ...

[0002] When using solar collectors 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 Device to drive the solar collector to follow the sun to achieve synchronous tracking of the sun

An existing class of ideal tracking devices can realize synchronous tracking in both azimuth and elevation angles, but there are problems such as complex structure, high manufacturing cost, high tracking energy consumption, and low reliability.
