Description
Technical field
The utility model relates to tower type solar energy thermal power generation heliostat field, relates in particular to the adjustable novel heliostat of a kind of hot spot.
Background technology
At present, existing solar heat power generation system mainly contains slot type, tower and dish formula three basic forms of it.And tower-type solar thermal power generating system adopts a large amount of heliostats that sunshine is gathered on the heat dump on the heat absorption tower, and heating working medium produces high temperature and high pressure steam, the driving steam turbine generating.Wherein heliostat is the important component part of tower-type solar thermal power generating system, be used for the solar radiation collection that will disperse and project heat dump, thereby the photo-thermal of realizing solar power tower is changed.
Heliostat is a kind of beam condensing unit that is comprised of minute surface, mirror holder, tracking drive mechanism and control system thereof etc., is used for following the tracks of receiving the also heat dump of reflected sunlight heat absorption top of tower, and be one of the main device in tower type solar energy thermal power generation power station.
At present, the common form of heliostat reflecting surface mainly contains: (1) monolithic plane or curved-surface reflection side; (2) large plane or the curved-surface reflection side of some small size plane compositions.For the first heliostat form, monolithic level crossing general size is less, although manufacturing cost is lower, the heliostat installation and transportation are convenient, but for extensive irregular tower type solar thermo-power station Jing Chang, need the huge heliostat of quantity, strengthened Jing Chang control and scheduling difficulty, and the cleaning of heliostat, maintenance difficulties are larger.And the monolithic curved reflector, for solar power tower, the heliostat focal length is large, curvature is less, therefore require all higher to hot bending die precision and the machine-building level of monolithic curved reflector, this has increased the heliostat manufacturing cost undoubtedly, increase power station initial investment cost, limited the extensive development of tower type thermal generation.For the second heliostat form, by the optically focused concave mirror that some small size level crossings are processed and are spliced and have certain curvature by precision optical machinery, it all has higher requirements to mechanical technology, batch workmanship, through engineering approaches installation etc.After the in a single day installation typing of this type heliostat was finished, its curvature mirror just can not be transferred again, therefore can't regulate in real time hot spot as required, and it is inadequate to focus on dirigibility.The problem that causes focusing accuracy to descend owing to factors such as face shape, physical construction variation, extraneous blast will appear in heliostat inevitably in During Process of Long-term Operation, cause that its accuracy correction is wasted time and energy, single mirror maintenance cost is higher.And some small sizes plane forms the large-area planar reflecting surface, although manufacturing process, installation difficulty are slightly low, spotlight effect is not as curved-surface reflection side.
The utility model content
The defective that exists in order to overcome above-mentioned technical matters, the utility model provides a kind of hot spot adjustable novel heliostat, by regulating each reflector element angle, changes its reflected light path, is met the flare of requirement.
The utility model discloses following technical scheme:
The novel heliostat that a kind of hot spot is adjustable comprises several reflector elements, and each reflector element center is equipped with central rotating shaft, and described reflector element and described central rotating shaft are rotationally connected, and described central rotating shaft drives described reflector element and carries out angular adjustment.
Preferably, described novel heliostat, its reflector element are level crossing or curved mirror.
Preferably, described novel heliostat, its reflector element is comprised of several level crossings or curved mirror.
Preferably, described novel heliostat, its level crossing or curved mirror are positioned at same plane or are arranged in curved surface by the certain way splicing.
Preferably, described novel heliostat, its reflector element are polygon.
Preferably, described novel heliostat is provided with appropriate gap between its reflector element.
Preferably, described novel heliostat, the central point of its each reflector element is positioned at same plane.
The beneficial effects of the utility model are:
(1) by regulating each reflector element angle of heliostat, can be met the hot spot that shape, size, optically focused quality etc. require, have stronger adaptability.
(2) problem of focusing accuracy decline will appear causing owing to factors such as face shape, physical construction variations in heliostat inevitably in During Process of Long-term Operation, and utilize heliostat provided by the utility model, the reflector element angle is simply adjusted, can realize again obtaining required hot spot, therefore can effectively reduce single mirror maintenance cost, improve the optically focused precision.
(3) can send at any one time as required different instructions and change the angle that each reflector element rotates, realize the real-time adjusting of hot spot, it is strong to focus on dirigibility.

Embodiment
The below is further described the utility model with specific embodiment by reference to the accompanying drawings:
Such as Fig. 1, the novel heliostat that a kind of hot spot is adjustable comprises several reflector elements, reflector element is quadrilateral in the present embodiment, can also be the reflector element such as Fig. 4, Fig. 5, Fig. 6 form during implementation, but be not limited to this, each reflector element can also be other polygons; Described reflector element center is equipped with the central rotating shaft (not shown), and described reflector element and described central rotating shaft are rotationally connected, and described central rotating shaft drives described reflector element and carries out angular adjustment; Block for reducing the anti-shade that reaches between reflector element of heliostat wind, be provided with appropriate gap between the described reflector element.
Such as Fig. 1, in the present embodiment, each reflector element is comprised of some profiles, measure-alike level crossing or curved mirror, but is not limited to this, also can adopt as required level crossing or curved mirror differently contoured, size during implementation; Heliostat shown in Figure 1 comprises " 1 ", " 2 ", " 3 ", " 4 ", " 5 " five reflector elements, and reflector element quantity is unrestricted during implementation; Described five reflector element central points are respectively O, A, B, C, D, the central point of each reflector element at grade, wherein A, O, B are on same straight line, C, O, D are on same straight line, and " 1 ", " 2 ", " 3 ", " 4 " 4 reflector elements can rotate around its central shaft a, b, c, d respectively.
The reflector element Angulation changes, then the reflected light path of each reflector element changes, and the launching position of its central point on heat dump changes thereupon, and respective change occurs in light spot shape and size thus, realizes the hot spot adjusting.It should be noted that, when carrying out the hot spot adjusting, can regulate any angle of a reflector element, and work as " 1 ", " 2 ", " 3 ", " 4 " four reflector elements simultaneously when its central shaft rotates to an angle, light spot shape and big or small variation effect are more obvious.
