Stealth Cover for Reducing Noise of Mobile Diesel Generator and Infrared Target Signature

Abstract

A stealth cover for reducing the noise of a mobile diesel generator and infrared target features belongs to the technical field of noise reduction and heat insulation devices, and in particular relates to a stealth cover for reducing the noise of a mobile diesel generator and infrared target features. The invention provides a stealth cover for reducing the noise of a mobile diesel generator and infrared target features, which has good heat insulation and noise reduction effect, can effectively reduce the infrared radiation intensity of an exhaust pipe port, and is convenient for transportation and installation. The invention comprises a heat-insulating and sound-absorbing base, a heat-insulating and sound-absorbing wall is arranged upwards around the heat-insulating and sound-absorbing base, and a heat-insulating and sound-absorbing top cover is arranged on the upper end of the heat-insulating and sound-absorbing wall. The surrounding wall, the heat-insulating and sound-absorbing wall and the heat-insulating and sound-absorbing top cover are all flexibly connected; the heat-insulating and sound-absorbing wall is also equipped with an exhaust silencer with low infrared characteristics, and the air inlet of the exhaust silencer is connected to one end of the heat-insulated exhaust pipe. The other end of the heat-insulated exhaust pipe is placed in the heat-insulated and sound-absorbing enclosure.

Description

technical field [0001] The invention belongs to the technical field of noise reduction and heat insulation devices, and in particular relates to a stealth cover for reducing the noise of a mobile diesel generator and the characteristics of an infrared target. Background technique [0002] A large number of mobile diesel generators are deployed in the army, which is an essential equipment for the army to generate electricity in the field. However, it is found that the mobile diesel generators have high noise, high temperature of the motor casing and exhaust pipe, and infrared target characteristics when used in the field. The strong problem not only seriously affects the working and rest environment of the troops, but also exposes the position of the troops and even the command center by the equipment, which will cause great damage to the concealment of the troops during wartime, and is very easy to be detected by the enemy using noise or infrared detection equipment.

AI Technical Summary

Problems solved by technology

[0003] At present, in order to reduce the noise of power generation equipment, sound insulation covers are usually used to reduce noise pollution, but in order to achieve better sound insulation and noise reduction effects, the walls of the sound insulation cover are relatively heavy, and the cover body is mainly an integral structure to reduce sound leakage. It is convenient for transportation and quick installation required for the troops to use in the field, and does not consider the infrared target characteristic factors of the cover body

Existing technology only considers the impact of noise reduction on the exhaust pipe opening, but does not consider the strong infrared radiation spots existing at the exhaust pipe opening and the infrared radiation intensity of the muffler shell, and lacks the noise and infrared radiation of mobile diesel generators.
