Abstract

The invention discloses a photovoltaic driving linear Fresnel solar energy heat collector, and is used for realizing the comprehensive utilization of opto-thermal and photovoltaic technologies. The photovoltaic driving linear Fresnel solar energy heat collector comprises a fixing photovoltaic cell panel, a mobile photovoltaic cell panel, a linear Fresnel reflector group, a linkage mechanism, a driving motor, a storage battery, a control device, a parallel type absorbing pipe beam, a trapezoid top cover, a glass sealing cover and a heat insulation structure; the parallel type absorbing pipe beam, the trapezoid top cover, the glass sealing cover and the heat insulation structure are formed to be an absorber; the fixing photovoltaic cell panel is fixed on the heat insulation structure at the top part of the absorber, and the mobile photovoltaic cell panel is arranged at the outside of the linear Fresnel reflector group; the mobile photovoltaic cell panel and the linear Fresnel reflector group are commonly connected to the linkage mechanism, the driving motor and the control device. The photovoltaic driving linear Fresnel solar energy heat collector combines the photovoltaic technology with the linear Fresnel opto-thermal technology, and solves the problem that a linear Fresnel type heat collector tracking system and other devices rely on the intensive power supply of the outer part.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a photovoltaic-driven linear Fresnel type solar heat collector. Background technique [0002] Solar energy is one of the effective ways to alleviate energy shortage, solve problems such as environmental pollution and greenhouse effect. At present, there are mainly two utilization methods of solar energy: photovoltaic and photothermal. [0003] Solar photovoltaic utilization mainly relies on photovoltaic panels to receive solar radiation to directly output direct current, or convert it to alternating current output through electrical equipment such as inverters. Solar thermal utilization mainly uses various forms of heat collectors to focus and collect solar radiation. The heat obtained can be used to heat water to generate steam to generate electricity, provide chemical reaction heat for fuel production and conversion, or meet other industrial needs....
