Cycloid type transmission device of heliostat

Abstract

The invention provides a cycloid type transmission device of a heliostat. Pitching transmission of the heliostat is conducted by an upper box body, the upper box body is supported by an upper box body support, the first torque rotating in the pitching direction is output through a first output flange, and the first output flange is driven by a first transmission device body located inside the upper box body support to rotate; the upper box body is fixedly mounted on a lower box body support; and the lower box body support is rotationally supported by a lower end cover and driven by a second transmission device body to rotate. The upper box body and a lower box body are of a box body structure, the height of the sun is positioned through rotation of the first output flange in the upper box body, the horizontal orientation of the sun is adjusted through rotation of the lower box body support, accordingly the orientation and pitching of the heliostat are positioned, and the spatial orientation of the heliostat is improved. Meanwhile, power transmission is conducted through the box body structure, the mounting structure is stable, and impulsive force resistant capacity is high, so that the work reliability of the transmission device of the heliostat is improved.

Description

technical field [0001] The invention relates to the technical field of heliostats, in particular to a cycloid heliostat transmission device. Background technique [0002] Under the premise of fossil energy depletion, the development of renewable energy industry has become the development focus of all countries. Tower-type solar thermal power generation was first designed and built by former Soviet scientists in 1950. The tracking transmission device of the heliostat is composed of azimuth and pitch. Orientation mechanism composition. The output stage of the tracking transmission device of the heliostat is generally a transmission type such as an enveloping worm gear pair, a planetary gear pair, and a parallel gear pair. [0003] The tracking transmission device of the tower solar thermal power generation requires a high-precision operating state, but the high-precision slewing mechanism often has weak structural rigidity and poor impact resistance. The working environment ...

Problems solved by technology

[0003] The tracking transmission device of tower-type photothermal power generation requires high-precision running state, but the high-precision slewing mechanism often has weak structural rigidity and poor impact resistance.

The working environment of the tracking transmission device of the tower solar thermal power generation heliostat is often accompanied by strong winds and other characteristics, and the working load increases with the square order of the wind speed. In order to ensure the stable operation of the heliostat, the carrying capacity under extreme working conditions should be considered in the design , so existing products have disadvantages such as bulky structure and high manufacturing cost
