A device and method for comprehensive utilization of solar energy based on solar optical fiber

Abstract

A comprehensive solar energy utilization device based on solar optical fiber comprises a comprehensive solar energy collector system, a power generating system, a lighting system, a heat energy supply system and a control system. Diversion utilization is conducted on sunlight energy obtained by Fresnel lenses through heat-resisting quartz couplers and the optical fiber of the comprehensive solar energy collector system, the sunlight energy is connected into the lighting system, the power generating system and the heat energy supply system, and the light energy is utilized to the maximum by setting the specific distance between the heat-resisting quartz couplers and the Fresnel lenses and the area of the end portions of the heat-resisting quartz couplers. Clean and healthy sunlight is evenly guided into a room through a solar optical fiber light guiding and lighting system, and a comfortable and healthy lighting environment is provided for people. Meanwhile, the purpose that in some areas where all-day lighting is needed, the daylight electric lighting is replaced, and the electric charge expense is greatly saved is achieved. Meanwhile, the power generation and heat energy utilization of solar energy are comprehensively considered, the comprehensive utilization efficiency of solar energy is improved, and consumption of traditional energy is reduced.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of solar energy, in particular to a device and method for comprehensive utilization of solar energy based on solar optical fibers. Background technique [0002] With the rapid development of my country's economy and the increasingly serious problems of energy shortage and environmental pollution, energy conservation, emission reduction and low-carbon life have become the development trend of all walks of life. my country is rich in solar energy resources, and the total annual solar radiation of more than two-thirds of the country's land area exceeds 5.0 GJ / m 2 , the annual average sunshine hours are more than 2200 hours. Especially in the vast North China and Northwest China, there is sufficient sunshine, which provides good natural conditions for the development and utilization of solar energy. [0003] As urban buildings tend to be high-rise and dense, only relying on traditional light...

Problems solved by technology

[0006] In the existing patents related to solar fiber optic light guide lighting, there are various disadvantages, such as patent 201020621250.4, when the sunlight cannot be directly irradiated, the lighting effect will be very poor, and the utilization of solar heat energy is not considered at the same time ; Patents 200920277492.3 and 201220708663.5 do not consider the comprehensive utilization of solar energy, and cannot get rid of the consumption of traditional energy; After that, it cannot be automatically adjusted, etc., and the direction of the tracking device needs to be adjusted manually on a regular basis

Patent 201320638567.2 is to convert solar energy into electrical energy and then perform lighting, so that the loss of light energy utilization is relatively large, and the solar panel is not completely perpendicular to the sunlight, and the efficiency of light energy generation is low

Patent 201510187982.4 does not consider the thermal energy utilization of solar energy
