Heliostat device

Abstract

The invention relates to a heliostat device, which comprises a reflection mirror, a mirror surface support, a horizontal movement assembly, a vertical movement assembly, a base and a mirror surface support frame. The reflection mirror is arranged on the mirror surface support; the vertical movement assembly is arranged at the two ends of the mirror surface support; the mirror surface support frame and the base are connected with the horizontal movement assembly; a transmission assembly of the horizontal movement assembly comprises an upper installation base, a lower installation base, a driving gear and a driven gear; the mirror surface support frame is connected with an upper installation disc; the upper installation base is rotatably connected with the lower installation base; the driven gear is arranged at the periphery of a central axis tube of the upper installation base; the driving gear on an output shaft of a first planet gear speed reducer is engaged with the driven gear; the base is connected with the lower installation base; two transmission assemblies are supported at the two ends of the mirror surface support frame respectively; each transmission assembly comprises a bearing pedestal end cover, a bearing pedestal and a shaft head; the shaft head is rotatably connected with the bearing pedestal; the two ends of a shaft sleeve are connected with the shaft head; and the bearing pedestal end cover is connected with the bearing pedestal. The heliostat device is high in positioning and tracking precision.

Description

technical field [0001] The invention relates to a tracking device, in particular to a heliostat device for tracking the sun, and belongs to the technical field of solar energy utilization tracking. Background technique [0002] The automatic tracking heliostat in the solar power generation device is composed of several reflectors installed on the frame that automatically tracks the movement of the sun. The frame drives the reflector to track the sun and irradiates the reflected light to the heat collector to realize heat storage and power generation. [0003] At present, heliostats generally use a vertical shaft superimposed on a horizontal shaft, and the double shafts are driven to form a T-shaped heliostat transmission system. That is, the horizontal shaft drives the worm gear through the motor, so that the heliostat can rotate through the horizontal shaft, and the vertical shaft drives the worm gear through the motor, so that the heliostat can rotate through the vertical ...

Problems solved by technology

That is, the horizontal shaft drives the worm gear through the motor, so that the heliostat can rotate through the horizontal shaft, and the vertical shaft drives the worm gear through the motor, so that the heliostat can rotate through the vertical shaft, but the output shaft of the traditional worm gear reducer and The input shafts are not on the same plane. Therefore, this transmission method not only has low transmission efficiency and low precision, but also has a large loss, which makes the service life short and will bring a certain transmission error to the heliostat. When the transmission error is magnified After hundreds or thousands of times, the tracking effect of the heliostat will be seriously abnormal, and the overall light-gathering efficiency of the heliostat will decrease as a result.
