A focusing data processing method of solar concentrating lens

Abstract

The present application discloses a focusing data processing method of a solar concentrating lens, and provides a focusing system, which includes a concentrator, a light guide plate and a camera, the apex of the convex surface of the concentrator is fixed on a horizontal ground, and the The concave array of the optical device is provided with a plurality of specular reflection sheets, the light guide plate and the camera are arranged directly above the light concentrator, and are located on the center line of the light concentrator, and the light guide plate can be independently It is composed of a small illuminating lamp that is turned on / off, and the application also discloses a method for processing focusing data by using the above system. Through this method, the error angle of the lens can be calculated more accurately; the time for obtaining the measurement data required for lens focusing can be reduced; and it is suitable for batch focusing. Save time and improve focusing efficiency.

Description

technical field [0001] The application belongs to the technical field of photothermal power generation, and in particular relates to a focusing data processing method of a solar concentrating lens. Background technique [0002] The focusing method of solar concentrating lenses usually includes two ways of focusing on the sun and focusing on imaging principles. [0003] Focusing on the sun, focusing directly under the sun, the most primitive and simplest way of focusing. Adjust the light spot of each reflector of the dish concentrator to the relative position of the heat collector. The light spot formed by each plate corresponds to the position of the Stirling receiving port. Within the adjustable range of the reflector, As far as possible, the spot distribution should be as uniform as possible to avoid hot spots. [0004] Focusing on the sun is very difficult in practical applications. First of all, during the entire focusing process, the tracking system needs to run all ...

Problems solved by technology

Third, when adjusting the focus, the operators are all working at heights, and at the same time, the scanning of the focus spot during the operation of the system is very dangerous

Fourth, it is also severely affected by the weather. Tracking and focusing cannot be performed on rainy days, which makes the installation period largely uncertain

[0006] Focusing based on the imaging principle can only be used in an environment where the sun is not very strong, and installation requires space, so it is not suitable for batch focusing
