Problems solved by technology

For the heliostats whose transmission mechanism is placed at the center of gravity, most of them need to remove part of the mirror unit and support rods to reduce the interference with the column, resulting in a greatly reduced rigidity of the support device
In addition, in the existing heliostats, the support device relies on the transmission mechanism to resist the wind load in the avoidance and retracted state, which requires very high rigidity of the transmission system, thus increasing the equipment cost

Embodiment Construction

[0024] The heliostat of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the heliostat of the present invention includes a converging curved surface (ie, a reflector) spliced ​​by several reflector units 1 , a support device for fixing the reflector, and a transmission mechanism 5 . Wherein the supporting device includes a column 7, a supporting grid 3, a counterweight clamping device 6 and a truss beam 4. The truss beam 4 is connected with the column 7 through the transmission mechanism 5 . The support grid 3 and the counterweight clamping device 6 are respectively installed at both ends of the truss beam 4 .

[0026] refer to image 3 As shown, any curve D can be tangent to the curve by changing the included angles α and β between adjacent reflector units 1, and the curvature of the curve D is very small in actual use requirements, so it can be considered that the tangent point and ...

Abstract

The invention discloses a heliostat. The heliostat comprises a reflecting surface composed of a plurality of reflector units which are spliced together, a supporting device for fixing reflectors and a transmission mechanism; the supporting device comprises an upright, a supporting net rack and a truss girder. The truss girder is connected with the upright through the transmission mechanism, the supporting net rack is mounted at one end of the truss girder and is of a quadrangular pyramid net rack structure; and the reflector units are mounted at net rack nodes of the quadrangular pyramid structure of the supporting net rack. The heliostat provided by the invention is convenient for operation, easy to process and high in structure rigidity, and the surface precision of a reflecting condensing curve can be ensured.

Description

technical field [0001] The invention relates to a heliostat, in particular to a heliostat capable of adjusting the light-condensing curved surface of a reflector. Background technique [0002] Heliostats are devices that collect solar radiant energy and are used to track the sun and reflect sunlight to a fixed location. Heliostats include reflective surfaces, supporting devices, transmission mechanisms and tracking control systems. The reflective surface of the heliostat is a quadratic surface. Reasonable support devices can improve the surface accuracy of the reflective surface, increase the projected light energy of the heliostat, facilitate the processing, assembly and debugging of the heliostat, and help reduce the the cost of. [0003] In the existing heliostat technology, the concentrating curved surface of the reflecting surface is mostly attached to the support device with a fixed curved surface installation position, and the support device with a curved surface in...
