Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The infrared smoke screen generating device of the present invention uses the pressure difference inside and outside the smoke screen particle tank as the initial power source of the particle movement, and transports the particles to the nozzle. There is a set of smoke particle acceleration and centrifugal diffusion system that accelerates the particles for the second time and obtains centrifugal force, so that when the particles are ejected from the nozzle, a larger infrared smoke cloud is formed. Parameters such as infrared smoke cloud formation speed, smoke density, and smoke particle flow can be controlled only by adjusting the internal pressure of the particle tank and accelerating the velocity of the swirling airflow, without changing the structure of the device.

Abstract

The invention belongs to the technical field of infrared stealth, in particular to an infrared smoke screen generation device. The infrared smoke screen generation device comprises a particle tank (3) for storing smoke screen particles (4), a control valve (5), a conveying pipe (6) and a nozzle (9), wherein the particle tank (3) is connected with the conveying pipe (6) through the control valve (5); the nozzle (9) is mounted at the tail end of the conveying pipe (6); the air pressure in the particle tank (3) is greater than the external ambient pressure; after the control valve (5) is opened, the smoke screen particles (4) in the particle tank (3) are output due to the air pressure difference, and reach the nozzle (9) through the conveying pipe (6); and the smoke screen particles (4) are sprayed out by the nozzle (9) to form an infrared smoke screen. The infrared smoke screen generation device realizes an acceleration and centrifugal diffusion technology of the smoke screen particles, and can adjust the pressure in the particle tank and the flow speed of air in an acceleration and rotation increasing system to control the particle flow of a smoke screen cloud cluster, the forming speed of the smoke screen cloud cluster, the smoke screen density and the like.

Description

technical field [0001] The invention belongs to the technical field of infrared stealth. Background technique [0002] At present, with the development of infrared stealth material technology, a variety of infrared stealth shielding materials have been researched. For different infrared detection devices and different use environments, a suitable infrared stealth shielding material can always be selected to meet the requirements. Therefore, in the various measures of anti-infrared imaging tracking measurement, infrared smoke screen has become an effective and feasible means. However, there are few researches on the device for throwing these infrared stealth materials to form an infrared shielding layer, which also hinders the application of this technology in infrared stealth. Therefore, how to design a throwing device to throw out these materials with infrared shielding properties to form smoke clouds and realize the effect of infrared target stealth is also a key issue. ...
