Abstract

The invention relates to a heliostat transmission system capable of increasing transmission precision, which comprises a decelerator, a motor, an input shaft, a gear pair and an output shaft, wherein a transmission group is arranged in the decelerator; a first-stage transmission force of the transmission group is worm and gear transmission; the input shaft is mounted on the decelerator is connected with the transmission group in a transmission manner; the motor is connected with the transmission group so as to drive the input shaft to rotate; the input shaft is connected with the output shaft in a transmission manner through the gear pair; the heliostat transmission system also comprises at least backlash elastic piece; and the backlash elastic piece is connected with the input shaft or / and the output shaft so as to eliminate a gap between the gear pair. According to the invention, the heliostat transmission system is independent of gear processing precision and worm and gear transmission precision; reasonable layout is processed through a transmission stage; in addition, the heliostat transmission system solves technical problems of lower heliostat transmission precision and efficiency, insufficient sensitivity, poor reliability, complex processing assembly, high manufacture cost and the like.

Description

technical field [0001] The invention relates to the field of tower-type solar thermal power generation, in particular to a heliostat transmission system capable of improving transmission precision. Background technique [0002] Tower-type solar thermal power generation uses a large number of heliostats to gather sunlight to the heat absorber on the receiving tower, heats the working fluid, generates high-temperature and high-pressure steam, and drives the steam turbine to generate electricity. The heliostat is a concentrating device composed of a reflector, a mirror frame, a tracking device and its control system. It is one of the core devices in the tower solar thermal power generation system. Among them, the tracking device is mainly responsible for the rotation and positioning of the heliostat in the heliostat system, and its performance directly determines the working efficiency of the heliostat, thereby affecting the power generation efficiency of the entire system. Th...
