A kind of airtight observation window for civil air defense to avoid strong emp light from damaging human eyes

Abstract

The invention discloses an airtight observation window for civil air defense which prevents human eyes from being damaged by strong EMP light, and relates to the technical field of civil air defense equipment. The airtight airtight observation window for air defense to avoid EMP strong light damage to human eyes, including fixed frame, glass plate, light sensor, compressed air bottle, air intake pipe, one-way solenoid valve, hollow glass plate, through hole, diffuse reflection mechanism and light blocking mechanism, the glass plates are respectively embedded in the left and right sides of the fixed frame, the light sensor is fixedly installed on the top of the left side of the fixed frame, the compressed air bottle is fixedly installed on the inner top of the fixed frame, and the top of the air intake pipe is fixedly connected to the The mouth of the compressed air bottle communicates with the inner cavity of the compressed air bottle. The airtight airtight observation window, which prevents EMP strong light from damaging human eyes, reflects the light in a large area toward the light source through the operation of the diffuse reflection mechanism, which greatly reduces the light penetrating the left side of the hollow glass plate. At the same time, it operates synchronously through the light blocking mechanism. Can completely block the residual light.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to an airtight observation window for civil air defense that prevents EMP strong light from damaging human eyes. Background technique [0002] In civil air defense projects, most of the airtight doors are equipped with airtight observation windows, which is convenient for indoor personnel to observe the outside. During the war, the electromagnetic pulse generated by EMP weapons is used to destroy the enemy's electronic equipment. At the same time, the connection between the civil air defense project and the outside world may be damaged. Destruction and exposure, the strong light produced by EMP attacks in the atmosphere has the characteristics of high intensity and wide range. When the strong light is instantly irradiated in the underground and dark passage, although the door body can withstand the electronic pulse, the observation window It cannot effectively pr...

Problems solved by technology

[0002] In civil air defense projects, most of the airtight doors are equipped with airtight observation windows, which is convenient for indoor personnel to observe the outside. During the war, the electromagnetic pulse generated by EMP weapons is used to destroy the enemy's electronic equipment. At the same time, the connection between the civil air defense project and the outside world may be damaged. Destruction and exposure, the strong light produced by EMP attacks in the atmosphere has the characteristics of high intensity and wide range. When the strong light is instantly irradiated in the underground and dark passage, although the door body can withstand the electronic pulse, the observation window It cannot effectively prevent the direct penetration of light from causing damage to the eyes of indoor personnel. The existing airtight observation window is basically composed of a single glass plate. process, but it will not be greatly disturbed in the process of light transmission, so that after it enters the glass plate through the air and then enters the air, the intensity of the light will not be greatly reduced, and it is often used in sunglasses that reduce light penetration The material is not suitable for a closed observation window. If an observation window made of this material is used in a room with dark ambient light, it will affect the normal observation of the outside world by the indoor personnel.
