A solar energy concentrating device

Abstract

The invention relates to a solar energy collecting device. The solar energy collecting device mainly comprises a light reflecting device, an east-west supporting rotation device, a north-south supporting rotation device, a light receiving framework supporting device, a light receiving framework, a light receiver and a solar tracking system. The light reflecting device is formed by splicing a large round table and a bottom connection round table. The large opening portions of the two round tables both face upwards, and the small opening portions of the two round tables face downwards. The round tables are hollowed out inside. The height of the large round table is equal to that of the light receiving framework, and the taper angle of the large round table is 90 degrees. Under the automatic control action of two sets of circuits, by rotating the two sets of the supporting rotation devices, the light reflecting device can conduct two-way real-time tracking on solar rays in the east-west direction and the north-south direction on the daytime, the solar rays can be irradiated into the large opening portion of the large round table in a vertical or near-vertical mode and be further projected onto the four side faces and the bottom face of the light receiving framework in a vertical or near-vertical mode through reflection, and the light receiver is irradiated. The light receiver can be a high-temperature solar collector tube or a flat plate collector or a solar cell panel. A light gathering system and a light receiving system are combined or separated in a modular mode.

Description

technical field [0001] The invention relates to a solar energy gathering device, which is mainly used in the fields of solar heat collection, solar photovoltaic power generation and the like. Background technique [0002] Solar energy is a safe, environmentally friendly, sustainable and clean energy. When it reaches the surface of the earth, the energy flow density is very low, and it is intermittent and unstable. For this reason, in order to obtain useful power, it is often necessary to adopt a large-area collection device. Around the use of solar energy, people have developed various types of devices, such as flat plate collectors, vacuum tube collectors, trough collectors, tower collectors and dish collectors, etc., but some solar energy utilization devices, Because of the low efficiency and high cost, in general, the economy cannot compete with conventional energy sources. For a considerable period of time in the future, the further development of solar energy utilizat...
