Embodiment Construction

[0015] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, the present invention includes: a first solar roof module 5, a second solar roof module 6, a first load-bearing beam 3a, a second load-bearing beam 3b, a third load-bearing beam 3c and bolts 4 (4a, 4b). The first and second solar roof modules 5 and 6 are composed of a photovoltaic cell 2 and a thermal bimetal 1, the photovoltaic cell 2 is a thin-film photovoltaic cell, and the photovoltaic cell 2 is pasted on the surface of the thermal bimetal 1, so The thermal bimetal sheet 1 is a double-layer metal sheet welded together by two metals with a relatively large expansion coefficient difference. In the thermal bimetal sheet, the side of the metal with a large expansion coefficient is arranged upward. The metal sheet is bent toward the metal side with a large expansion coefficient, and the upper end of the first solar roof m...

Abstract

The invention relates to a solar roof capable of opening and closing automatically to dissipate heat. The solar roof capable of opening and closing automatically to dissipate heat comprises a first solar roof module, a second solar roof module, a first spandrel girder, a second spandrel girder, a third spandrel girder and bolts, wherein each of the first solar roof module and the second solar roof module consists of photovoltaic cells and thermal bimetal sheets; the photovoltaic cells are adhered to surfaces of the thermal bimetal sheets; the upper end of the first solar roof module is fixed on the first spandrel girder through a bolt; the lower end of the first solar roof module is in lap joint at the upper end of the second solar roof module; the upper end of the second solar roof module is fixed on the second spandrel girder through a bolt; the lower end of the second solar roof module is in lap joint on the third spandrel girder; and the first solar roof module and the second solar roof module are arranged on a southward roof of a building. The solar roof can automatically ventilate and dissipate heat in summers, is closed to keep warm in winters, and has a good application prospect.

Description

technical field [0001] The invention relates to a solar roof capable of automatically switching on and off for heat dissipation, belonging to the field of building roof structures. Background technique [0002] Making full use of solar power in buildings to reduce building energy consumption is an effective way to save energy in buildings. In recent years, the state has continued to strengthen its support for solar photovoltaic buildings in terms of policies and resources. Solar photovoltaic buildings have shown a trend of rapid development. The combination of photovoltaics and buildings can realize the integration of photovoltaic buildings, which can realize solar power generation, energy saving and environmental protection. It can also save a lot of land resources. The roofs of buildings such as industrial plants and railway stations are mostly metal roofs, and there are a large number of places for installing photovoltaic cells, which provides conditions for building inte...
