A hollow security glass with a built-in light-shielding layer

Abstract

The invention discloses hollow security glass with a built-in light shielding layer. The hollow security glass comprises a hollow layer, a water storage cavity, a scratch-resistant layer and bulletproof glass. The left side of the hollow layer is provided with the scratch-resistant layer, and the right side of the hollow layer is provided with the bulletproof glass. The water storage cavity is arranged inside the hollow layer, a first water receiving pipe is disposed at the upper end of the hollow layer, a material uniformizing grid is horizontally disposed in the water storage cavity close tothe first water receiving pipe, and material uniformizing holes are evenly distributed in the surface of the material uniformizing grid. The lower end of the hollow layer is provided with a second water receiving pipe, the first water receiving pipe and the second water receiving pipe are connected with a filter tank through a communicating pipe, the communicating pipe connected with the first water receiving pipe is provided with a circulating water pump, and a filtering mesh plate is arranged in the filter tank. The hollow security glass is simple and reasonable in structure, and the switching between light transmission and light shielding is achieved conveniently. In the later stage, suspended particles can be replaced to meet the needs of different colors, water is used as a filling liquid and can absorb heat, and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to a hollow security glass with a built-in light-shielding layer. Background technique [0002] Security can be understood as an acronym for "safety protection". According to the interpretation of the current Chinese dictionary, the so-called safety means no danger, no infringement, and no accidents; the so-called precaution means precautions and precautions, and precautions refer to making preparations to deal with attacks or avoid being victimized, and precautions refer to prevention and protection . Based on the above explanations, we can give the following definition of security precautions: prepare and protect to deal with attacks or avoid victims, so that the protected objects are in a safe state where there is no danger, no infringement, and no accidents. It is obvious that safety is the purpose, and prevention is the means. To achieve or realize the purpose of s...

Problems solved by technology

In addition, the bulletproof glass made of tempered glass also has the disadvantage of poor heat resistance, and it is easy to break when subjected to thermal shock, which limits its application range.
