Portable Fresnel-lens solar automatic-tracking power generating and heating dual-purpose device

Abstract

The invention discloses a portable Fresnel-lens solar automatic-tracking power generating and heating dual-purpose device, belonging to the field of solar utilization devices. A Fresnel lens (2) is detachably arranged on a support (1) which is fixedly arranged on a two-dimensional real-time automatic tracking device (3), a heat concentrating functional entity (6) located near a focus part of the Fresnel leans (2) is also provided, one side of the heat concentrating functional entity (6) is provided with a photovoltaic battery board (7), the other side of the heat concentrating functional entity (6) is provided with a holophote (8), the heat concentrating functional entity (6) is arranged on a functional conversion shaft (5) located on the support (1), the functional conversion shaft (5) can be rotated to realize the mutual conversion between power generation and heat concentration, a bearing frame (10) is additionally arranged on the support (1) and is provided with a heated body (9) which is bound to be located in an optical path of sunlight reflected by the holophote (8). The device has the dual functions of power generating and heating which can be converted conveniently, thereby facilitating the utilization of solar energy and improving the sufficient and effective application of solar energy; and moreover, the device has small size and light weight, and is convenient to carry and particularly suitable for field battle troops.

Description

technical field [0001] The invention belongs to the field of solar energy utilization devices, and relates to a portable Fresnel lens solar automatic tracking dual-purpose device for power generation and heating. Background technique [0002] Fresnel lens solar energy utilization devices have been used for a long time, and most of them are single-function power generation devices or heating devices. Overcoming the inherent disadvantages of vacuum heat collecting tubes and flat plate heat collectors, especially for power generation devices, can greatly reduce the area of ​​photovoltaic panels, the volume and weight of the entire device, and facilitate the automatic tracking of solar energy, but so far there is no The dual functions of power generation and heating that can be easily converted on demand, and the Fresnel lens solar energy utilization device with solar automatic tracking device, this affects the convenient utilization of solar energy to a certain extent, and also...
