Description
Technical field
The utility model belongs to solar light-heat power-generation technical field, particularly a kind of line focusing reflective support device based on space truss structure.
Background technology
Solar energy thermal-power-generating technology gets up to be converted into heat energy by solar energy collecting by condenser, then produces the generating of high temperature and high pressure steam driving steam turbine.
Line-focusing solar condensing thermal power generation technology is a kind of common form of current solar energy thermal-power-generating, solar-energy collecting is become wire hot spot by the Jing Chang consisted of polygonal mirror, then utilize receiver to be heat energy by light energy conversion, by heat-conducting fluid, heat absorption is delivered to heat interchanger.In heat interchanger, the heat of heat-conducting fluid is used to heating water and generates water vapor, and then utilizes water vapor driving steam turbine acting generating.
In whole line-focusing solar thermal electric generator, condenser field is the most key assembly.Mirror field light gathering efficiency is directly connected to the transformation efficiency of final luminous energy to electric energy.Due in solar energy thermal-power-generating technology for the requirement of focusing ratio and receiver limited width, therefore certain requirement is proposed to the width of wire hot spot.In order to obtain the narrower focal beam spot of width, a kind of solution uses with the catoptron of radian to replace level crossing, but be difficult to ensure due to the machining precision of differential of the arc catoptron, thus causes spotlight effect to weaken and the rising of processing cost.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of line focusing reflective support device based on space truss structure, solve the problem that the large cost of differential of the arc catoptron difficulty of processing is high, and considerably reduce the deadweight of reflection support, effectively reduce its manufacturing cost.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Based on a line focusing reflective support device for space truss structure, comprise the main shaft 1 be connected with tracing system, two sway braces 2 are stretched out in described main shaft 1 both sides at equal intervals symmetry, and entablature 3 end face of sway brace 2 is directly connected with catoptron 4.
Described main shaft 1 is space triangular truss-frame structure, vertical with sway brace 2.
Described sway brace 2 is plane trigonometry truss-frame structure, and its entablature 3 is with radian.
Described entablature 3 is forging and stamping preformed steel structure assembly, the radian on entablature 3 and catoptron 4 cambered surface suitable.
Described entablature 3 end face is connected with the back side of catoptron 4, fixes or the mode of pasting connects preferably by machinery.
Described reflection holder device adopts steel construction, by being welded to connect between each connecting rod, crossbeam.
The utility model entablature of arc process support arm 2 needed for minute surface in advance before assembling, make it have the arc identical with minute surface, after support completes welding assembly, catoptron 4 is posted and fixed in entablature end face completely by structure glue or mechanical system.
The beneficial effects of the utility model are: based on the principle of mechanical cold deformation, utilize holder device of the present utility model to fix the radian of level crossing, can fast and low-cost ground preparation differential of the arc minute surface.Compare with existing hot bending processing globoidal mirror technology, owing to can directly use common plane mirror, therefore processing cost significantly reduces.In addition, because support have employed space truss structure, under the prerequisite ensureing supporting structure intensity, considerably reduce deadweight, the minimizing of rolled steel dosage significantly can reduce the manufacturing cost of holder part.
