Problems solved by technology

The transmission or driving devices of these heliostats are specially designed and processed for heliostats, and cannot be standardized and generalized.
The structure of the gear transmission box is complicated, and the processing cost of the gear is high, so the cost of the heliostat transmission box remains high. In addition, the gears are easy to wear, and the wear will seriously affect the tracking and positioning accuracy of the heliostat, and the maintenance cost is high.
For the transmission box used for large heliostats, due to the large wind load torque of large heliostats, the transmission box must output a large torque, which will inevitably result in a huge structure of the transmission box

Abstract

The invention discloses a hydraulic drive mechanism of a heliostat. The cylinder earrings (28, 29) of first and second linear hydraulic cylinders (6, 7) are articulated with a support plate (5) on a support beam (4), and piston rod earrings (27, 9) are articulated with a drive arm plate 11. A support arm (26) of a support fork (23) is articulated with a support plate (18) of a connection cylinder (22). A cylinder earring (44) of a third linear hydraulic cylinder (16) is articulated with an upper support plate (13), and a piston rod earring (20) is articulated with the support plate (18). The linear hydraulic cylinders (6, 7) drive a horizontal main shaft (15) to rotate, and drive a heliostat reflecting surface (24) and the linear hydraulic cylinder (16) to rotate around a horizontal main shaft axis (100); and the third linear hydraulic cylinder (16) drives the connection cylinder (22) to drive the heliostat reflecting surface (24) to rotate around a common axis (50), so that the heliostat realizes sun tracking.

Description

technical field [0001] The invention relates to a hydraulic drive mechanism of a heliostat in the field of tower-type solar thermal power generation. Background technique [0002] At present, there are mainly three types of solar thermal power generation, which are tower solar thermal power generation, trough solar thermal power generation and dish solar thermal power generation. Among them, the tower solar thermal power generation method has the advantages of high concentration ratio and high power generation efficiency. The principle of the tower solar thermal power generation method is that multiple heliostats arranged in the heliostat field track the sun, reflect and focus the sunlight on the surface of the heat absorber on the tower, where the heat transfer medium is heated to high temperature, and then through a heat exchanger to generate steam, which is used to drive a conventional steam turbine to generate electricity. In tower-type solar thermal power generation, t...
