A funnel-type Fresnel lens focusing solar heat collector

Abstract

The invention discloses a funneling Fresnel lens focusing solar heat collection device, and belongs to the field of conducting energy gathering and heat energy conversion through solar energy. The funneling Fresnel lens focusing solar heat collection device comprises a traction ring and the like. The traction ring is installed on a heat preservation plate, and a traction rope penetrates through the traction ring. A heat collection tube assembly is installed at the bottom of a funneling Fresnel lens and connected with a water inlet tube and a return water tube. A balance weight is installed on a supporting plate. A first collision reduction column and a second collision reduction column are installed on the two sides of the funneling Fresnel lens respectively. A base is connected with a rotating gear motor and driven by the rotating gear motor to rotate around the axis in a horizontal plane. A pitching gear motor is installed on the supporting plate and connected with the heat preservation plate through the traction rope. The heat preservation plate is installed outside the Fresnel lens. The funneling Fresnel lens focusing solar heat collection device is a solar product which can be used for industrial production, agricultural production and life of urban and rural residents and is convenient to use and practical, is high in heat production efficiency and wide in application range, and has good market development prospect.

Description

technical field [0001] The invention belongs to the field of energy accumulation and heat energy conversion by utilizing solar energy, and in particular relates to a solar energy product suitable for industrial and agricultural production or daily life of urban and rural residents. Background technique [0002] For the utilization of solar energy in the existing technology, although there have been many ideas and inventions before, but in terms of the role and efficiency of solar energy, there is currently no solar energy product that has reached a satisfactory level, that is, It is said that a lot of potential in solar energy has yet to be further developed. To utilize solar energy, it is first necessary to gather as much energy as possible in a limited space, and then effectively convert this light energy, such as converting it into thermal energy with a wide application value, and at the same time minimize the loss of converted energy . At present, the method usually ad...

Problems solved by technology

If a farmer applies this device to a biogas digester, he or she will not use it because the cost is higher than the value of the gas obtained

Therefore, the solar water heaters in the prior art fail to solve the problem of farmers in northern regions using biogas in winter
