Problems solved by technology

The glass melting furnace used in this method needs to reach a high temperature of about 1700°C to melt the rock. This heating method not only consumes a lot of energy, but also is difficult to operate. If large-scale construction is required, it will undoubtedly cause huge energy consumption. loss

Abstract

The invention relates to a light-converging heating device based on a Fresnel lens. The light-converging heating device based on the Fresnel lens device comprises a Fresnel light converging system which is used for converging sunlight, a Fresnel light converging system pitching mechanism, a Fresnel light converging system polar axis overturning mechanism, a Fresnel light converging system transverse horizontal movement mechanism, a Fresnel light converging system longitudinal lifting mechanism and a control system, wherein the Fresnel light converging system pitching mechanism is used for adjusting the angle of the Fresnel light converging system through pitching motion, the Fresnel light converging system polar axis overturning mechanism is used for adjusting the polar axis of the Fresnel light converging system by means of rotational motion, the Fresnel light converging system transverse horizontal movement mechanism is used for changing the position of the Fresnel light converging system through transverse horizontal movement, the Fresnel light converging system longitudinal lifting mechanism is used for changing the position of the Fresnel light converging system by means of longitudinal horizontal movement, and the control system is used for controlling the movement of the Fresnel light converging system pitching mechanism, the Fresnel light converging system polar axis overturning mechanism, the Fresnel light converging system transverse horizontal movement mechanism and the Fresnel light converging system longitudinal lifting mechanism so as to realize the optimal convergence of sunlight by the Fresnel light converging system.

Description

technical field [0001] The invention relates to the technical field of solar energy, and more specifically, to a concentrating heating device based on a Fresnel lens. Background technique [0002] Solar energy can be considered as inexhaustible. At present, the utilization of solar energy includes power generation, heating and other forms, and its specific realization forms are also varied. For example, solar panels can be directly used to generate electricity to charge electrical appliances such as mobile phones and street lamps; solar energy can also be used for heating. However, a prominent problem currently exists is that the energy conversion efficiency is too low, resulting in poor practical application effect. [0003] Deserts occupy nearly 40% of the world's land area. Desertification management has long been concerned by human beings, and the global process of desertification management is currently accelerating. The harm of desertification to human beings shoul...
