Description
Technical field
The utility model relates to solar energy thermal-power-generating and solar thermal utilization technical field, and particularly heliostat systems technology field specifically is meant a kind of heliostat structure that realizes the solar tracking location.
Background technology
From nineteen fifty former soviet design built the 1st the tower type solar energy thermal power generation small test device in the world and 1976 France and built up after the 1st electric power reach the tower-type solar thermal power generating system of 100kW on the Pyr mountain; Since the eighties in 20th century; States such as the U.S., Italy, France, Spain, Japan, Australia, Germany, Israel set up various dissimilar experiment demonstration plants and commercialized running device in succession, have promoted the development and the commercialization process of solar energy thermal-power-generating technology.The existing solar heat power generation system in the world mainly contains groove type line-focusing system, tower system and dish formula system 3 big fundamental types.
Heliostat is a very important equipment of Conversion of energy initial period in the tower-type solar thermal power generating system.In tower system, usually adopt thousands of heliostats, through autonomous control system Continuous Tracking solar radiant energy separately, and energy focusing to the heat dump of cat head, the form with heat energy is used then.Therefore, the design of heliostat is one of important step of tower-type solar thermal power generating system design, is to reduce cost of electricity-generating, realizes the business-like basis of solar energy thermal-power-generating.
Heliostat is made up of support, kinematic train, reflective mirror and control system four parts usually.Support is the support section of whole heliostat, with stable the linking together of each parts.Reflective mirror is fixed on the support, through the adjustment at any time of kinematic train, sun incident light is reflexed on the heat dump of heat absorption tower, and present most producers all adopt the ultra-clear glasses silvered mirror.The mode that control system adopts orientation, pitching twin shaft to drive is controlled heliostat from the motion tracking sun.Mostly the heliostat reflecting surface of existing practical applications is individual layer differential of the arc face hot bending glass silver both at home and abroad; Adopt single upright supports; The heliostat of this version is realized following the tracks of with programme controlled open loop control mode usually; Whole mirror holder relies on fixed single upright column to support; The vertical direction turbine and worm deceleration mechanism that is provided with through the column upper end drives mirror holder realization azimuthal movement, realizes the elevation angle motion through the turbine and worm deceleration mechanism drive mirror holder of horizontal direction, has advantage simple in structure, that the antidumping performance is good.Yet, limited by machining accuracy, there is the difficulty that is difficult to go beyond in the tracking error aspect that single column heliostat drive gap of this form causes; And high precision gear train and the making of bend glass mirror make the heliostat manufacturing cost high, and the protection of silver mirror silver coating is anxious to be waited to capture; Simultaneously, the inevitable mechanically deform of mirror holder also brings challenges to the heliostat spotlight effect.
