Embodiment 1

[0034] Put the base cylinder 1 horizontally into the pre-drilled holes on the wall, then install the sealing gaskets 2 inside and outside the wall respectively, and finally fix the windows from the inside and outside of the wall with the fastening ring 3. At this time, it can be used as an ordinary observation window when installing test equipment, repairing and debugging the smoke test box.

Embodiment 2

[0036] The second embodiment is based on the first embodiment, used for testing conditions such as temperature and humidity of the smoke screen test chamber and sampling of smoke screen aerosol concentration. During implementation, on the outside of the wall of the smoke screen test box, the convex ring of the circular end cover 4 is further connected to the fastening ring 3, and the middle hole can pass most temperature sensors, humidity sensors and aerosol sampling heads. In the smoke screen performance evaluation test, the window can be used as a sampling window. After sampling, it can be blocked with a rubber plug of appropriate size to continue the test under sealed conditions.

Embodiment 3

[0038] The third embodiment is to do infrared and laser attenuation tests on the basis of the second embodiment. First, put various glass and other special optically transparent materials processed into appropriate sizes into the bottom of the hole in the middle of the circular end cap, and then screw the pressure ring 5 in and fix it to form a test window for optical signal transmission. It can transmit electromagnetic waves such as infrared and laser, and can also play a sealing role to ensure that the smoke screen material does not leak out, thereby creating good test conditions.

Abstract

The invention relates to a movable multifunctional window body used for a smoke screen test box. The movable multifunctional window body comprises a base cylindrical shell, two seal washers, two fastening rings, two round end caps and two compression rings, wherein the base cylindrical shell is in a cylindrical shape, and the two ends thereof are provided with external threads; the two seal washers are respectively sleeved on the external threads at the two ends of the base cylindrical shell; each fastening ring is provided with inner threads with two different diameters along the axial direction, and the inner threads with the larger diameter is matched and connected with the external threads of the base cylindrical shell; a flat surface is arranged at one side of each round end cap, anda convex ring is arranged at the other side of each round end cap; the convex ring is provided with external threads which are matched and connected with the inner threads with the smaller diameter in the fastening ring; the middle of each round end cap is provided with concentric holes with different diameters, wherein a first concentric hole with the smaller diameter is positioned at the middleof the convex ring of the each round end cap, and a second concentric hole with the larger diameter is positioned at the middle of the flat surface of the each round end cap and is provided with inner threads; and the compression rings are provided with external threads which are respectively matched and connected with the inner threads of the concentric hole with the larger diameter on each round end cap.

Description

【Technical Field】 [0001] The invention relates to a movable multifunctional window for a smoke screen test box, in particular to a movable multifunctional window for a smoke screen test box suitable for indoor smoke screen performance evaluation, and belongs to the technical field of photoelectric countermeasures. 【Background technique】 [0002] The smoke screen test box is an important equipment for evaluating the photoelectric countermeasure performance of smoke screen in the laboratory. The smoke screen test box should have a transmission channel for input and output of photoelectric signals, a channel for collecting and analyzing smoke screen concentration, and a channel for detecting test conditions such as temperature and humidity in the smoke box. These channels should be able to adapt to multiple signals such as infrared, laser, and visible light. In addition, it is required to be able to disassemble or replace the optically transparent materials in the smoke box accordin...
