Solar furnace device

Abstract

The invention discloses a solar furnace device. The solar furnace device comprises a furnace body, a heat collector, a light gathering device and an adjusting device, wherein the heat collector is arranged on a heat collection plane of the furnace body, and the included angle phi between the heat collection plane and the horizontal plane is the latitude of a using area; the light gathering device is used for gathering sunlight into the heat collector, and the light gathering device is a fixed-focus Fresnel lens; the adjusting device is connected to the furnace body and comprises a solar hour angle rotating frame and a rotating motor both arranged on the furnace body, and the rotating motor is used for controlling the rotation amount of the light gathering device relative to the heat collection plane in one day; and the adjusting device further comprises a declination adjusting device for controlling the rotating angle theta of the light gathering device relative to the plane normal line of the solar hour angle rotating frame. According to the solar furnace device, the light gathering device always faces the sunlight and receives the direct sunlight, and the light gathering device focuses the sunlight on the heat collector so that the solar energy can be better utilized and the utilization efficiency of the solar energy can be improved.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, and more specifically relates to a solar furnace device. Background technique [0002] Solar energy has the advantages of being universal, powerful, long-lasting, and harmless. Based on these advantages, people have never stopped exploring the utilization of solar energy. [0003] However, solar energy also has shortcomings such as dispersion, intermittent, randomness, etc., which restrict the utilization of solar energy. In the solar energy utilization methods in the prior art, the sunlight is usually focused and collected, but the focusing effect is mediocre and cannot form a good converging effect on the sunlight, and the radiation intensity of the sunlight is low. In order to solve the above problems, the prior art generally needs to obtain a higher focusing effect by enlarging the lens area, resulting in an increase in the cost of the solar furnace, resulting in failure to ...

Problems solved by technology

[0003] However, solar energy also has shortcomings such as dispersion, intermittent, randomness, etc., which restrict the utilization of solar energy

In the solar energy utilization methods of the prior art, the sun's rays are usually focused and collected, but the focusing effect is average, and it cannot form a good converging effect on the sun's light, and the sun's radiation intensity is low

In order to solve the above problems, the prior art generally needs to obtain a higher focusing effect by enlarging the lens area, resulting in an increase in the cost of the solar furnace, resulting in failure to better realize the utilization of solar energy in many fields
