Controllable double-state light reflecting and concentrating solar heat collecting generator

Abstract

The invention belongs to a composition member of a solar light-heat central air-conditioning system, which relates to the technical field of solar electricity generation and heating. The device solves the problem that the use efficiency of the heat collecting pipe and reflecting mirror combined type solar collecting device is low in spring and autumn. The composition member comprises a main framework, a heat collecting pipe support frame, a heat collecting pipe and a light reflecting and concentrating mechanism, wherein at least two solar battery light reflecting and concentrating cover support devices form one group, at least two support shafts or shaft support structural bodies are arranged at each group, at least one solar battery light reflecting and concentrating cover is movably fixed and connected on each support shaft or shaft support structural body, and the composition member is controlled and fixed in a certain state. The free selection and the proportion matching of the whole system for obtaining heat and electric power are realized. The composition member can obtain the solar energy throughout the year according to requirements, can be used for heating and air conditioning in winter and summer and can be used for electricity generation in spring and autumn. Compared with the prior art, the composition member fully utilizes solar resources and photovoltaic and light-heat equipment and improves the performance price ratio by one time.

Description

【Technical field】 [0001] The invention relates to the technical field of solar power generation and heat supply, in particular to a reflective and concentrating solar heat collection power generation device. It is one of the components of the solar thermal system. Especially one of the components of the central air conditioning system. 【Background technique】 [0002] Reflective concentrating is the basic form of solar energy utilization in solar central air-conditioning systems, and it is the earliest solar thermal technology to achieve commercial operation. [0003] The technical scheme adopted usually includes a curved mirror reflector installed on the support frame, a vacuum heat collecting tube fixed on the focal line of the curved mirror reflector by means of the support frame, and a device for driving the curved mirror reflector to track the sun through the support frame. The tracking mechanism, when working, the curved mirror reflector focuses the incident sunlight ...
