Heliostat of double-push-rod structure

Abstract

The invention discloses a heliostat of a double-push-rod structure. The heliostat comprises reflectors, heliostat frames, a main beam, a supporting base, a connecting base and a first bearing. The main beam is used for mounting of the heliostat frames. The heliostat frames are used for supporting the reflectors. The main beam is connected with and arranged on the connecting base. The main beam can rotate around itself to do horizontal rotational motion. The supporting base and the connecting base are connected through the first bearing, and the connecting base can rotate around the supporting base to do azimuth rotational motion. The connecting base is driven by an azimuth telescopic push rod to do azimuth rotational motion around the vertical axis of the supporting base. The main beam is driven by a horizontal telescopic push rod to do horizontal rotational motion around the horizontal axis of the main beam. The heliostat of the double-push-rod structure has a short transmission chain, and the precision of the rotation angle is easy to control. Moreover, the number of main parts is small, and the machining and manufacturing difficulty and the manufacturing cost are reduced.

Description

technical field [0001] The invention belongs to the field of solar thermal power generation, in particular to a heliostat with a double push rod structure. Background technique [0002] In the field of energy, solar energy, as a clean and renewable energy, is being used more and more widely. In the field of solar power generation, solar power generation methods include photovoltaic power generation and thermal power generation technologies. With the development of science and technology, especially the rise of computer control technology, solar thermal power generation technology is another new solar energy utilization technology after photovoltaic power generation technology. Solar thermal power generation technology uses a large number of reflectors to gather the energy of direct sunlight in a focused manner, heat the working fluid, generate high-temperature and high-pressure steam, and use the steam to drive a steam turbine to generate electricity.
