Problems solved by technology

For the Stirling solar thermal power generation system, it must also be equipped with a high-precision automatic tracking system with a tracking error of ≤0.03° to obtain a uniform high temperature area > 1000 ° C. The heating medium drives the Stirling engine to convert solar energy (heat energy) It is the conversion of mechanical energy into electrical energy; although the level of automatic tracking is getting higher and higher with the development of science and technology, the high cost, low tracking accuracy and high failure rate of the tracking system actually used in the field of solar energy are still the main problems for domestic and foreign promotion and application. technical barrier

Abstract

The invention discloses an integrate device of a solar power generating station automatic tracking system. The integrate device of the solar power generating station automatic tracking system comprises a main shaft and one or multiple concentric circle rails with different radiuses around the main shaft, wherein an integrated base platform structure is supported by the concentric circle rails through an idler wheel, a plurality of sunshine collecting devices are arranged on the integrated base platform structure, the integrated base platform structure is driven by driving devices which are arranged on the concentric circle rails and rotates around the main shaft; and the driving devices are connected with an azimuth angle automatic tracking system. By adopting a ground device which is composed of the multiple concentric circle rails and the base platform structure method in an integrated and floor type which rolls upwards, the integrate device of the solar power generating station automatic tracking system achieves a consensus automatic tracking function of a plurality of power generating units of the entire generating station for one time and has the advantages of being simple in structure, stable in operation and easy to realize.

Description

technical field [0001] The invention belongs to the technical field of solar energy applications, and relates to an automatic tracking device, in particular to an automatic tracking system integration device for a solar power station. Background technique [0002] Due to the rotation of the earth itself and the movement around the sun, if the supporting automatic tracking system is used, the power generation efficiency of the photovoltaic power generation system can be increased by more than 20%. For the Stirling solar thermal power generation system, it must also be equipped with a high-precision automatic tracking system with a tracking error of ≤0.03° to obtain a uniform high temperature area > 1000 ° C. The heating medium drives the Stirling engine to convert solar energy (heat energy) It is the conversion of mechanical energy into electrical energy; although the level of automatic tracking is getting higher and higher with the development of science and technology, t...
