Abstract

The invention discloses a Stirling power generator with a spherical Fresnel solar thermal collector and belongs to the technical field of solar power generation. According to the Stirling power generator, based on the Stirling cycle and the power generating mode of utilizing the solar thermal effect, the structural rigidity of a Fresnel lens is guaranteed through a solar thermal collection deviceprovided with the spherical Fresnel lens, the lens is not liable to deform through the semi-spherical structure, and light rays are not liable to defocus; an umbrella-shaped supporting frame is adopted, so that stability is high, and the converging light rays are not shielded; meanwhile, sunlight can be converged orthogonally at any sun inclination angle, and thus the convergence ratio of the lensand the solar utilization rate are increased; the optical distance that the sunlight passes through the lens is decreased, absorption of the lens to the sunlight is reduced, the solar absorptivity ofa system is better guaranteed in the light condensing aspect, and the power generation efficiency of the power generator is improved effectively; and the power generator can be further matched with other power storage devices in use for storing power, materials with high energy consumption are replaced, the production cost is reduced, and pollution is reduced.
