Abstract
The invention relates to a multi-position height adjustable line focusing reflective support device, which comprises a main shaft connected with a tracking system, wherein the main shaft is arranged below a support cross beam horizontally; and more than two vertical adjustable fulcra are arranged on the support cross beam at equal intervals and are connected with a reflecting mirror base in a movable mode. On the basis of the principle of mechanical cold deformation, the radian of a plane mirror is regulated by utilizing the support device to manufacture a micro-arc mirror surface quickly with low cost; and compared with the conventional technology of machining a cambered surface mirror by hot bending, the multi-position height adjustable line focusing reflective support device has the advantages that: due to the adoption of the ordinary plane mirror, the machining cost is reduced substantially; and for a micro-arc mirror, the complexity of a machining process is reduced greatly, and the arc-shaped accuracy of the reflecting mirror is improved, so the condensing efficiency of the line focusing reflecting mirror can be improved substantially, and the installation debugging cost of a system can be reduced.
Description
Technical field
The invention belongs to the solar light-heat power-generation field, be specifically related to the adjustable for height line focusing reflective support device of a kind of multiposition.
Background technology
The solar energy thermal-power-generating technology is by condenser solar energy collecting to be 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 present solar energy thermal-power-generating, the Jing Chang that consists of by polygonal mirror becomes the wire hot spot with solar-energy collecting, then utilize receiver that light energy conversion is heat energy, by heat-conducting fluid with heat absorption and be delivered to heat interchanger.The heat of heat-conducting fluid is used to heating water and generates water vapor in heat interchanger, and then utilizes water vapor driving steam turbine acting generating.
In whole line-focusing solar thermal electric generator, the condenser field is the most key assembly.Mirror field light gathering efficiency is directly connected to final luminous energy to the transformation efficiency of electric energy.Since limited for requirement and the receiver width of optically focused ratio in the solar energy thermal-power-generating technology, therefore certain requirement has been proposed the width of wire hot spot.In order to obtain the narrower focal beam spot of width, a kind of solution is to use the catoptron with radian to replace level crossing, but owing to the machining precision of differential of the arc catoptron is difficult to guarantee, 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 adjustable for height line focusing reflective support device of a kind of multiposition, solved the high problem of the large cost of differential of the arc catoptron difficulty of processing.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
The adjustable for height line focusing reflective support device of a kind of multiposition, comprise the main shaft 1 that links to each other with tracing system, main shaft 1 is horizontally placed on supporting traverse 2 belows, supporting traverse 2 has a plurality of and is parallel to each other, on each supporting traverse 2, uniformly-spaced be provided with plural vertical adjustable fulcrum 3, each adjustable fulcrum 3 is flexibly connected with corresponding catoptron base 4, so that catoptron base 4 is highly adjustable.
Described main shaft 1 is metal circular tube, and is vertical with supporting traverse 2.
Described adjustable fulcrum 3 is the support with strip hole 7, links to each other with catoptron base 4 by strip hole 7, and adjustable fulcrum 3 with on the end that supporting traverse 2 is connected does not arrange fine adjustment screw 6.
The invention has the beneficial effects as follows: based on the principle of mechanical cold deformation, utilize holder device of the present invention to regulate 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 the common plane mirror, so processing cost significantly reduces, and for differential of the arc mirror, also greatly reduces the complexity of processing technology and improved the degree of accuracy of catoptron arc.

Embodiment
Describe embodiments of the present invention in detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, the present invention is the adjustable for height line focusing reflective support device of a kind of multiposition, comprises the main shaft 1 that links to each other with tracing system, and main shaft 1 is metal circular tube, plays a part carrying and rotating shaft.Main shaft 1 is horizontally placed on supporting traverse 2 belows, supporting traverse 2 is comprised of with the channel-section steel that the catoptron width equates many length of parallel installation on steel pipe, have two kinds of effects of support structure and constitutional balance, each supporting traverse 2 is first-class to be arranged at intervals with five vertical adjustable fulcrum 3.
As shown in Figure 3, adjustable fulcrum 3 is take channel-section steel as basic structure, side opening strip hole 7, and fine adjustment screw 6 is installed in the top tapping, and the bottom is connected with supporting traverse 2, and catoptron base 4 is aluminum corner brace, passes strip hole 7 by bolt 8 and is fixed on the adjustable fulcrum 3.
The parts such as above-mentioned supporting traverse, adjustable fulcrum, catoptron base have formed frame structure, when the mounting bracket device, can adjust difference in height between the different catoptron bases 4 of picture frame by adjustable fulcrum 3 according to required minute surface radian, then plane mirror 5 is sticked together by silica gel and catoptron base 4.If find that after silica gel solidifies fully focusing effect is not ideal enough, can also by unclamping the set bolt at strip hole position, utilize 6 pairs of minute surface radians of fine adjustment screw to carry out the secondary adjustment, to reach best spotlight effect.
Utilize holder device of the present invention to connect plane mirror, holder device both played a supportive role, and also can carry out the differential of the arc to catoptron by the adjustable fulcrum of regulating holder device simultaneously and regulate, and follow the tracks of daylight by tracing system driving rotation.
