Manufacturing method of standard plate for detecting and comparing area and grey scale of heliostat

Abstract

The invention discloses a manufacturing method of a standard plate for detecting and comparing the area and grey scale of a heliostat. The manufacturing method includes the steps that a plurality of standard bare plates with the same size are prepared; mixed liquor for preparing dust and organic solvents is put into a liquid storage cavity of a liquid spray pen; mirror surfaces of the standard bare plates are fixed at an angle of inclination, pressure sensors are installed at the bottoms of the standard bare plates, and a nozzle of the liquid spray pen is tilted upwards to conduct spraying onto the mirror surfaces of the standard bare plates; the mass of each standard bare plate is weighed again through an electronic scale; according to the mass difference before and after dust spraying oneach standard bare plate, the dust stratification mass per unit area of the standard bare plates is calculated; and for each level of the standard bare plates, dust capacity measurement values are calculated and the error range is taken. According to the manufacturing method of the standard plate for detecting and comparing the area and grey scale of the heliostat, definition of the mirror area grey scale and manufacturing of the gray scale deposition standard plate are realized, and a foundation is laid for inspection of the field mirror area grey scale of the heliostat and improvement of cleaning and power generation efficiency of a tower type solar power station.

Description

technical field [0001] The invention relates to the field of making standard plates, in particular to a method for making a standard plate used for grayscale detection and comparison of the areas of heliostats. Background technique [0002] At present, the application of solar thermal power generation in practice is more and more widely, mainly in concentrating type, mainly including: tower type, trough type and dish type, etc. A tower solar thermal power generation system generally consists of four main parts: a heat absorbing tower, a heliostat array, a generator set, and a heat storage tank. [0003] The heliostat array is the core system, which belongs to the concentrating heat collection subsystem. The tower heliostat field is a concentrating system composed of multiple heliostats for concentrating solar radiation. Each heliostat continuously tracks the sun through its own independent tracking control device, and gathers the sunlight to the heat absorber on the top of...

Problems solved by technology

[0008] Based on this, in order to solve the problems raised in the background technology, the object of the present invention is to solve the problem of the gray scale of the existing heliostats, cooperate with the inspection trolley in the mirror field of the solar power station, and provide a method for making gray scale The standard plate method is used to effectively measure the gray scale of the field mirror area of ​​the heliostat, and the staff of the solar power station can know the gray scale of the mirror area in time to clean the mirror surface and improve the power generation efficiency of the solar power station
