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, and finally use the fastening ring 3 to fix the window from the inside and outside of the wall. At this time, it can be used as an ordinary observation window when installing test equipment, maintaining and debugging the smoke test chamber.

Embodiment 2

[0036] Embodiment 2 is based on Embodiment 1, and is used for testing conditions such as temperature and humidity in a smoke test chamber and sampling of smoke aerosol concentration. During implementation, on the outside of the wall of the smoke test chamber, the protruding ring of the circular end cover 4 is further connected to the fastening ring 3, and the hole in the middle can just pass most of the temperature sensor, humidity sensor and aerosol sampling head. During the smoke screen performance evaluation test, the window can be used as a sampling window. After sampling, it can be blocked with a rubber stopper of an appropriate size to continue the test under sealed conditions.

Embodiment 3

[0038] The third embodiment is based on the second embodiment, infrared and laser attenuation tests are done. First of all, special optically transparent materials such as various glasses processed into appropriate sizes are put into the bottom of the hole in the middle of the circular end cap, and then the pressure ring 5 is screwed in and fixed to form a test window for optical signal transmission. It can pass through infrared, laser and other electromagnetic waves, 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, and a 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 middle of 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 test chamber, in particular to a movable multifunctional window for a smoke test chamber suitable for indoor smoke performance evaluation, and belongs to the technical field of photoelectric countermeasures. 【Background technique】 [0002] The smoke test chamber is an important equipment for evaluating the performance of smoke photoelectric countermeasures in the laboratory. The smoke test box should have a transmission channel for photoelectric signal input and output, a channel for collecting and analyzing the smoke 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 various signals such as infrared, laser, and visible light. It is one of the main problems in the design and construction of the smoke box to ensure the transmission of the smoke box and to ensure the seal of the smoke...
