Device and method for detecting impurities and defects of toughened glass curtain wall on spot

Abstract

The invention discloses a device for detecting impurities and defects of a toughened glass curtain wall on spot, and the device comprises a polarized light source, a detection host and a connection line, wherein the polarization light source and the detection host are connected by the connection line; the polarized light source comprises a polarizer, an LED light source, a first power module, a first wireless communication module, a first control module, an iron plate for attracting a magnet, and a first housing, and is used for forming linearly polarized light; the detection host comprises animage acquisition module, a human-machine interface module, a second power module, a second wireless communication module, a second control module, a magnet, and a second casing, and is used to collect a photo-elastic image and an original image, and analyze and determine the information of impurities and defects about the type, size, and location. The invention is suitable for detecting impurities and defects on a serviced tempered glass curtain wall on spot.

Description

technical field [0001] The invention relates to the technical field of tempered glass curtain wall detection, in particular to a device for on-site detection of impurities and defects of a tempered glass curtain wall. Background technique [0002] Glass curtain walls are more and more widely used in modern buildings. Since the strength of tempered glass is several times that of ordinary flat glass, tempered glass has good safety performance. For safety and strength considerations, most modern glass curtain walls use tempered glass. [0003] Impurities and defects inside the tempered glass can produce local stress concentration under certain conditions and cause the glass to self-explode. "On-line Detection Technology of Impurities and Defects in Tempered Glass for Doors, Windows and Curtain Walls" (Doors and Windows, 1, 2-6, 2009) analyzed the reasons for the self-explosion of tempered glass, pointing out that the self-explosion and shattering of tempered glass can generally...

AI Technical Summary

Problems solved by technology

[0006] (2) When the detection device detects a large-sized glass curtain wall, the size of the organic flat glass and the polarizer is too large to be convenient for detection

[0007] The mechanism of the detection device is relatively complicated, and the integration level is not high. It is inconvenient to detect the impurities and defects of the tempered glass curtain wall that has been in service on site.
