Abstract

The invention relates to the field of photo-thermal power generation devices, in particular to a tower type photo-thermal power generation system, a heliostat, a heliostat tracking driving device anda heliostat rotating table. The heliostat rotating table comprises a rotating table body, a reflecting mirror hinge seat arranged on the rotating table body and a pitch angle oil cylinder hinge seat arranged on the rotating table body. The heliostat rotating table is of a casting formed integrated structure, and the reflecting mirror hinge seat and the pitch angle oil cylinder hinge seat are integrally formed with the rotating table body in a casting manner. The heliostat rotating table is integrally formed, and it is ensured that the position precision obtained after primary machining is improved while rigidity of the rotating table is ensured. Compared with a current assembly type heliostat rotating table, the heliostat rotating table is high in precision, and the problems that the installation precision and rigidity of the current heliostat rotating table are low are solved.

Description

technical field [0001] The invention relates to the field of photothermal power generation equipment, in particular to a tower-type photothermal power generation system, a heliostat and its tracking drive device, and a turntable. Background technique [0002] In the tower-type photothermal power generation system, the function of the heliostat is to track, reflect, and focus sunlight, and accurately project it into the heat sink of the heat collection tower. As the first link of energy transfer, the heliostat is a key component to increase the energy density of solar energy. The tower heliostat includes a column, a tracking drive device installed on the column, a reflector installed on the tracking drive device, etc. The overall performance requirements of the heliostat are: high mirror reflectivity, high mechanical structure strength, stable operation, The spotlight has high positioning accuracy, flexible operation, easy installation and maintenance, and long working life....
