Embodiment Construction

[0022] In order to further improve the energy conversion efficiency of naturally clean and inexhaustible solar energy, and to popularize and apply it in many fields with huge energy consumption, the present invention provides a solar heat collection system. Breaking through the existing hot spot technology - the inherent thinking of the heliostat heat-concentrating lighthouse system, innovatively developed an optical principle that uses optical focusing, projection, reflection, etc., so that the sunlight can be constantly directed towards a fixed receiver. Therefore, no matter how the concentrating mirror rotates, the final principal optical axis still does not change, so the heat collecting system is temporarily defined as "fixed eyepiece" here.

[0023] Such as Figure 1 to Figure 3 As shown, it is a schematic diagram of the structure, a schematic diagram of the operating state and a schematic diagram of the principle of the optical path of a preferred embodiment of the pres...

Abstract

The invention discloses a solar energy collecting system of a heliostat, comprising an optical collector, a receiver and an electric control unit for controlling the optical collector to track sun. The solar energy collecting system of the heliostat is coaxially and integrally provided with a projecting mirror having overlapped focuses, relative to the surface of the optical collector, a through hole larger than the facula of the projecting mirror and smaller than the surface of the optical collector is arranged in the centre of the optical collector; a reflecting mirror is arranged at the other side of the optical mirror back to the projecting mirror; a mirror face assembly consists of the reflecting mirror, the optical collector and the projecting mirror; the receiver with a fixed position is arranged in an extending direction of a main optical axis of the reflecting mirror, a first motor is arranged on the main optical axis to drive the whole mirror face assembly to rotate around the centre of the reflecting mirror, and the first motor is connected with the electric control unit and controlled to operate. The invention can effectively improve solar focalizing ratio by over 100,000 times, and provide a new scheme for the utilization and the development of efficient solar energy collection.

Description

technical field [0001] The invention relates to a solar heat collection application device, in particular to a low-cost, high-efficiency use of solar energy heat collection application device, which can be used in many fields such as popular civil use and industrialized large-scale thermal power generation. Background technique [0002] A solar collector is a device that absorbs sunlight and transfers the generated heat to a heat transfer medium. The heat collector is a key component of the solar thermal utilization system. Different heat collection methods form different types of heat collectors, which can be roughly divided into focused and non-focused heat collectors. The efficiency of energy collection and the quality of energy collected by non-focused collectors are not high. The concentrating collector can concentrate the solar energy collected in a large area to a small area or even a point, and its concentration ratio is 10 4 The above can obtain high-quality, high...
