Description
Technical field
The present invention relates to a kind of solar thermal utilization and thermal electric generator, particularly a kind of Novel linkage heliostat.
Background technology
At present in solar energy thermal-power-generating field, it is high that tower thermo-power station has focusing ratio, the advantage that generating efficiency is high.The Jing Chang that tower thermo-power station is made up of multiple stage heliostat, by solar light focusing to the heat dump surface on high tower, the cost of its heliostat accounts for about 50% of power station cost.Calculate according to Sandia National Laboratory of the U.S., when to drop to every square meter reflective area be 100 dollars for the cost of heliostat, solar energy thermal-power-generating cost electricity price is 5.9 cents, now solar energy thermal-power-generating can be competed with conventional thermal power generation economically mutually, therefore how to cut down heliostat cost and just become the key reducing tower type thermal generation cost, there is important economic implications and the value of environmental protection.
The basic structure of separate unit heliostat mainly comprises several parts such as ground, column, motor, transmission case, control system, support and catoptron.Wherein catoptron is rack-mount, and support is by column and ground-based supports, and motor and transmission case composition driving mechanism drive catoptron to produce two dimensional motion.Driving mechanism can be divided into elevation angle driving mechanism and position angle driving mechanism, and both actings in conjunction make the mirror surface of heliostat can follow the trail of the sun all the time.The cost of driving mechanism accounts for about 50% of heliostat total cost, and the cost of position angle gear train is greater than elevation angle gear train.
