Abstract

The invention provides a heliostat azimuth angle digital hydraulic control system. The system comprises a hydraulic auxiliary element, a hydraulic power element, a digital hydraulic motor and a heliostat azimuth angle moving mechanism. Normal work of the digital hydraulic motor is guaranteed through the hydraulic auxiliary element. The hydraulic power element provides a high-pressure oil source for the digital hydraulic motor. The digital hydraulic motor is used for controlling movement of the heliostat azimuth angle moving mechanism. According to the system, the digital hydraulic motor is used for controlling the heliostat azimuth angle moving mechanism, the azimuth angle of a heliostat completely achieves vectorization and digitization, the debugging difficulty is reduced, the debugging period is shortened, the requirement on the cleanliness of hydraulic oil is reduced, system parameters do not need to be adjusted when the system is used for a long time, and high positioning precision is achieved.

Description

Technical field [0001] The invention relates to the field of tower photothermal power generation, in particular to a digital hydraulic control system for the azimuth angle of a heliostat. Background technique [0002] Tower solar thermal power generation is a solar concentrating thermal power generation technology. The use of this technology to generate electricity requires a tall central absorption tower on the open ground. An absorber is installed and fixed on the top of the tower, and a certain number of towers are installed around the tower. The heliostat, through the heliostat, gathers sunlight into the cavity of the receiver at the top of the tower to generate high temperature, and then passes through the heat exchanger to produce steam, and the steam drives the steam engine to generate electricity. The heliostat is a light-concentrating device composed of a supporting structure, a tracking transmission system and a reflecting mirror. It is used to track and reflect and con...
