Waterborne heliostat light-tracking system and light-tracking method thereof

Abstract

The invention relates to a waterborne heliostat light-tracking system and a light-tracking method thereof. The waterborne heliostat light-tracking system comprises a central tower, a secondary light gathering device for receiving sunlight reflected by a heliostat and disposed at the top of the central tower, at least one floating unit surrounding the central tower, a central processing unit, and asensing judging device; the floating unit includes a planar truss, a floating block fixed to a lower portion of the planar truss, and a supporting device disposed on the upper surface of the planar truss; the supporting device includes a truss frame bearer for bearing the heliostat and a power mechanism for driving the truss frame bearer to realize angle adjustment; and the sensing judging devicecomprises a light sensor fixed to the middle of the upper end surface of the heliostat, an angle sensor and a plurality of light judging devices fixed on the upper end surface of the heliostat.

Description

technical field [0001] The invention relates to a light tracking system and a light tracking method for a heliostat on water, belonging to the field of solar power generation. Background technique [0002] With the continuous burning of fossil fuels, the conventional energy available to human beings is getting less and less, and the use of fossil energy will be accompanied by harmful gas emissions, which seriously damages the ecological environment in which human beings live and seriously threatens human safety and security. Survive. In order to protect the ecological environment on which human beings depend, measures must be taken to reduce the consumption of fossil energy, vigorously develop clean, clean new energy and renewable energy, and take the road of green energy. [0003] Solar energy is the most abundant permanent energy source in the world. Solar thermal power generation is one of the main ways to utilize solar energy. A solar thermal power station equipped wit...

AI Technical Summary

Problems solved by technology

The existing tower-type solar thermal power plants are mainly built on land, and their disadvantages are: 1. Undulating terrain, which affects the construction scale and power generation efficiency of the solar thermal power plant; 2. The arrangement of the heliostat field needs to consider the shadow of the central tower Blocking, the arrangement is not compact enough; 3. The heliostat field adopts a separate dual-axis light tracking device, which has high tracking costs; 4. The cost of water resource mobilization is high; 5. The light tracking is not accurate enough
