Abstract

The invention relates to a dish type energy gathering support and a dish type energy gathering mirror adopting the dish type energy gathering support. The dish type energy gathering support and the dish type energy gathering mirror have the advantages of being high in sunlight tracking precision, high in light energy capture efficiency and sensitive in light intensity response. The dish type energy gathering support comprises a supporting column, a dish type energy gathering mirror supporting frame, an elevation angle adjusting device and a sunlight tracking steering device. The supporting column is connected with the elevation angle adjusting device through the sunlight tracking steering device, and the elevation angle adjusting device is connected with the dish type energy gathering mirror supporting frame. The dish type energy gathering support further comprises a sunlight tracking system. The sunlight tracking system comprises an outdoor light intensity acquisition sensor and a controller connected with the outdoor light intensity acquisition sensor. The elevation angle adjusting device and the sunlight tracking steering device are connected with the controller. The dish type energy gathering mirror is formed by splicing multiple dish type energy gathering mirror bodies, and the appearance of the dish type energy gathering mirror is matched with that of the above dish type energy gathering support. The utilization rate of solar energy can be increased.

Description

technical field [0001] The invention relates to the technical field of solar energy concentrating equipment, in particular to a dish-type energy-concentrating bracket and a dish-type energy-concentrating mirror. Background technique [0002] The solar energy irradiated on the earth in the prior art is very huge, and the solar energy irradiated on the earth in about 40 minutes is equivalent to the annual energy consumption of human beings all over the world. Compared with non-renewable resources such as coal, oil and natural gas, solar energy can be regarded as a truly inexhaustible clean energy. Different from photovoltaic power generation system, solar thermal power generation is a new energy utilization form of solar power generation, a new type of sunrise industry, and has very broad development prospects. The dish-type solar thermal power generation in the prior art uses concave mirrors to gather light and heat energy, then uses a Stirling engine to convert solar energy...
