Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 System diagram of the solar cogeneration system shown. The present invention is mainly composed of a supporting frame, a rotating parabolic concentrator 3, a concentrating photovoltaic cell group 2, a rotating hyperboloid spectrum control system 4 and a heat pipe water heater 5. The rotating parabolic condenser 3 is installed on the support frame 1, the focal axis of the rotating hyperboloid spectrum division control system 4 coincides with the focal axis of the rotating parabolic condenser 3, and is installed before the focus of the rotating parabolic condenser 3, and the focus of the rotating parabolic condenser 3 and the rotation The place where the left focus of the hyperbolic spectral control system 4 coincides. The convex surface of the rotating hyperboloid spectrum control system 4 faces the concave surface of the rotat...

Abstract

The present invention relates to a solar heating and power generation combined supply system. Said system includes the following several components: rotating parabolic saucer condenser, rotating hyperbolic spectral control system, light-gathering photovoltaic group battery and hot-pipe type water heater. Said invention also provides the concrete structure of the above-mentioned every portion and the working principle of said system.

Description

technical field [0001] The invention relates to a heat and power cogeneration system, in particular to a cogeneration system utilizing solar power and heat. Background technique [0002] At present, the known solar photovoltaic power generation uses flat-plate photovoltaic cells, which have the disadvantages of low light density and limited use of the solar spectrum, resulting in low efficiency of the entire system. At the same time, the high price of photovoltaic cells also restricts the large-scale promotion and use of flat-panel photovoltaic power stations. In Chinese patent 98117671.2, it is disclosed that a lens is used to achieve a high concentration ratio of sunlight to reduce the use area of ​​photovoltaic cells, and cooling water cools the photovoltaic cells to provide hot water, thereby improving the efficiency of photovoltaic power generation and realizing combined heat and power. But this method still projects all sunlight onto the photovoltaic cell, making phot...
