Abstract
A line focusing reflection support based on a space truss structure comprises a spindle connected with a tracking system, wherein the spindle is of a spatial triangular truss structure, two arms symmetrically extend out of two sides of the spindle at a uniformly-spaced mode and of planar triangular truss structures, and upper cross beams on two arms are directly connected with reflection mirrors so as to support the reflection mirrors and enable required arcs of the reflection mirrors to be kept. The line focusing reflection support is based on a mechanical cold deformation principle, utilizes a support device to adjust the radian of a plane mirror, and a micro-arc mirror plane can be rapidly prepared in a low-cost mode. Compared with an existing cambered surface mirror hot-bending machining technology and due to the fact that the common plane mirror can be directly used, the machining cost is remarkably reduced. In addition, the complex degree of a machining process of a micro-arc mirror is also greatly reduced, and the accuracy of the reflection mirror radian is improved. Therefore, the light-gathering efficiency of the line focusing reflection mirrors can remarkably improved, and the installation debugging cost of a system can be reduced.

Technical field
The invention belongs to solar light-heat power-generation technical field, particularly the line focusing reflective support based on space truss structure.
Background technology
Solar energy thermal-power-generating technology is, by condenser, solar energy collecting is got up to be converted into heat energy, 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 consisting of polygonal mirror, then utilizing receiver is heat energy by light energy conversion, by heat-conducting fluid by heat absorption and be 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.Because requirement and the receiver width for optically focused ratio in solar energy thermal-power-generating technology is limited, therefore the width of wire hot spot is proposed to certain requirement.In order to obtain the narrower focal beam spot of width, a kind of solution is to use with the catoptron of radian to replace level crossing, but because the machining precision of differential of the arc catoptron is difficult to ensure, thereby cause the rising of spotlight effect weakening and processing cost.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the line focusing reflective support based on space truss structure, solve the high problem of the large cost of differential of the arc catoptron difficulty of processing, and significantly reduced the deadweight of reflection support, effectively reduced its manufacturing cost.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
Line focusing reflective support based on space truss structure, comprises the main shaft 1 being connected with tracing system, and two sway braces 2 are stretched out in described main shaft 1 both sides uniformly-spaced symmetry, and entablature 3 end faces of sway brace 2 are 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, and the radian on entablature 3 and catoptron 4 cambered surfaces are suitable.
Described entablature 3 end faces are connected with the back side of catoptron 4, the mode of preferably being fixed or being pasted by machinery
Connect.
Described reflection holder device adopts steel construction, between each connecting rod, crossbeam by being welded to connect.
The present invention in advance according to the entablature of the required arc process support of minute surface arm 2, makes it have the arc identical with minute surface before assembling, and support posts and fixes catoptron 4 in entablature end face by structure glue or mechanical system after completing welding assembly completely.
The invention has the beneficial effects as follows: based on the principle of mechanical cold deformation, utilize holder device of the present invention to fix the radian of level crossing, can prepare differential of the arc minute surface in fast and low-cost ground.Compare with existing hot bending processing globoidal mirror technology, owing to can directly using common plane mirror, therefore processing cost significantly reduces.In addition, because support has adopted space truss structure, under the prerequisite that ensures supporting structure intensity, significantly reduced deadweight, the minimizing of rolled steel dosage can significantly reduce the manufacturing cost of holder part.
