Problems solved by technology

[0006] Using a curved reflector, due to the small curvature, the consistency in the production process is poor, and because the reflector is in different positions, the focal length of the light is not the same, different positions need to use different curved reflectors , which increases the complexity of making curved mirrors

Abstract

The invention relates to a Fresnel solar concentrating device. The Fresnel solar concentrating device comprises a Fresnel reflector device and a support adjustment device, wherein the Fresnel reflector device comprises a plurality of miniature Fresnel reflectors; the support adjustment device comprises a plane disc which is used for adjusting azimuth, a plane disc support device and bracket groups which are used for adjusting pitching angles of the Fresnel reflectors; the bracket groups which are used for adjusting the pitching angles of the Fresnel reflectors are installed on the plane disc which is used for adjusting the azimuth side by side; the miniature Fresnel reflectors of each row are arranged side by side and are inclined at the same angle; and all rows of the Fresnel reflectors form a zigzag shape in the same row and share the same focus. The azimuth of the miniature Fresnel reflectors is adjusted by a sun chasing device by controlling the rotation of the plane disc, and the pitching angles of the Fresnel reflectors are adjusted by controlling support cross rods of the miniature Fresnel reflectors, so that accuracy control can be realized; direct sunlight is irradiated on the miniature Fresnel reflectors, light and heat are gathered on heat collecting pipes by the miniature Fresnel reflectors, and the heat collecting pipes absorb the heat to heat internal working media for solar power supply.

Description

technical field [0001] The invention belongs to the field of solar thermal power generation, in particular to a Fresnel solar concentrating device. [0002] technical background [0003] Solar thermal power generation technology collects solar energy and converts it into heat energy through focused heat collection technology, and then uses it to generate high-temperature and high-pressure steam to drive a turbogenerator to generate electricity. [0004] Reflective linear Fresnel power generation is one of the four forms of solar thermal power generation at present. Its working principle is: through the rectangular mirror field composed of many flat single-axis rotating mirrors, it automatically tracks the sun, and then the sunlight It is reflected and gathered into the linear concentrator parallel to the height of the mirror field, and then absorbs sunlight through the coated steel pipe, and converts the light energy into heat energy, thereby heating the working medium flowin...
