Abstract

The invention relates to a heat collection and heat exchange device used for solar energy solar-thermal power generation. The heat collection and heat exchange device comprises a base and two supports, wherein a rotating shaft is arranged between the tops of the two supports, and a hydraulic cylinder is mounted on one of the supports; two frames are symmetrically and fixedly connected to the outer end of the rotating shaft, each frame comprises a heat collection pipe rack extending upwards and a hinged plate extending downwards, two support arms are symmetrically and fixedly connected to the left side and the right side of the heat collection pipe rack, and the end parts of a piston rod of the hydraulic cylinder are hinged and connected with the outer ends of the hinged plates. The heat collection and heat exchange device further comprises a first light reflecting plate, a second light reflecting plate, a third light reflecting plate and a fourth light reflecting plate, lug plates are respectively arranged at the two ends of the back face of each light reflecting plate, and a driven gear is fixedly connected onto one of the lug plates; the lug plate of the first light reflecting plate and the lug plate of the second light reflecting plate are respectively hinged and connected with the support arms on the left sides of the two frames, and the lug plate of the third light reflecting plate and the lug plate of the fourth light reflecting plate are respectively hinged and connected with the support arms on the right sides of the two frames. The heat collection and heat exchange device further comprises a first speed reducer, a second speed reducer, a third speed reducer and a fourth speed reducer which are mounted on the support arms and are provided with driving gears respectively; the driving gears of the speed reducers are respectively in gear engagement with the driven gears of the light reflecting plates.

Description

technical field [0001] The invention belongs to the technical field of solar power generation equipment, and in particular relates to a heat collection and heat exchange device for solar photothermal power generation. Background technique [0002] Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar heat, provide steam through heat exchange devices, and combine traditional turbogenerator technology to achieve the purpose of power generation. The use of solar thermal power generation technology avoids the expensive silicon crystal photoelectric conversion process, which can greatly reduce the cost of solar power generation. Moreover, this form of solar energy utilization has an incomparable advantage over other forms of solar energy conversion, that is, the water heated by solar energy can be stored in huge containers, and it can still drive steam turbines to generate electricity a few hours after the sun ...
