Heliostat used by solar power generating system

Abstract

The invention belongs to the technical field of heliostats, and particularly relates to a heliostat used by a solar power generating system. The heliostat comprises a drive shaft, a speed reducer, aninput shaft, a first fixing board, a second fixing board, a ring disc, a heliostat body, a round disc, a fixing ring, a gear ring, a first drive gear, a first one-way clutch ring, a second drive gear,a second one-way clutch ring, a first shaft, a first L-type board, a first shaft sleeve and the like. The first one-way clutch ring and the second one-way clutch ring make a first crank rocker mechanism and a second crank rocker mechanism work under different conditions of rotation of a motor, and then the heliostat swings in azimuth angle and elevation angle and keeps the proper angle with the sun all the time. By reducing one motor and one heliostat, the heliostat device achieves the same effect with a traditional heliostat device, so that the economic cost is reduced and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of heliostats, in particular to a heliostat used in a solar power generation system. Background technique [0002] At present, the heliostat device is a flat mirror device that directional projects sunlight, which belongs to the field of solar energy application technology. This device needs an azimuth adjustment mechanism and an elevation angle adjustment mechanism to adjust the angle of the heliostat to always ensure a suitable angle with the sun. . The azimuth angle adjustment mechanism and the altitude angle adjustment mechanism are generally driven separately by two shafts, and the two shafts are driven by their own motors, so that the design of the two motors increases a certain economic cost; in addition, the traditional fixed There are azimuth-pitch heliostats and spin-pitch heliostats in the heliostat device, and the design of the two heliostats also increases the economic cost; therefore, in order...

Problems solved by technology

The azimuth angle adjustment mechanism and the altitude angle adjustment mechanism are generally driven separately by two shafts, and the two shafts are driven by their own motors, so that the design of the two motors increases a certain economic cost; in addition, the traditional fixed There are azimuth-pitch heliostats and spin-pitch heliostats in the heliostat device, and the design of the two heliostats also increases the economic cost; therefore, in order to lower the economic cost of the traditional heliostat device, it is necessary to design A heliostat device requiring only one motor and one heliostat
