High overpressure type collective protection system

Abstract

The invention relates to the technical field of motor vehicle protection, in particular to a high overpressure type collective protection system which comprises a gas filtration ventilation device, anoverpressure measurement and control device, a high-pressure inflation device and a control center. The gas filtration ventilation device comprises a filtering absorber, an air volume measuring device and a speed regulating fan. The input end of the control center is connected with an output port of the air volume measuring device, the control end of the control center is connected with a motor of the speed regulating fan, the overpressure measurement and control device comprises an overpressure measurement component and an overpressure control component, the input end of the control center is connected with an output port of the overpressure measurement component, the control end of the control center is connected with an electric control valve, the high-pressure inflation device comprises an inflation pump, an inflation rubber strip, an inflation adjusting electromagnetic valve and a differential pressure transmitter, the inflation rubber strip is clamped in a vehicle door sealing clamping groove, an output port of the differential pressure transmitter is connected with the input end of the control center, and the control end of the control center is connected with the inflationadjusting electromagnetic valve. The system can establish in-vehicle ultra-high pressure protection and realize automatic control.

Description

technical field [0001] The invention relates to the technical field of motor vehicle protection, in particular to a high overpressure collective protection system. Background technique [0002] Under the conditions of nuclear, biological and chemical threats, it is necessary to protect the personnel in the vehicle to ensure that the personnel are not harmed by nuclear, biological and chemical pollution. At present, there are three forms of protection at home and abroad: [0003] a. Personal NBC protection; b. Overpressure NBC protection; c. Mixed NBC protection. Among them, the overpressure nuclear, biological and chemical protection is also called the overpressure collective protection. Under the premise that the overall sealing problem of the vehicle is basically solved, the poison filter ventilation device provides purified clean air and creates a certain overpressure inside the vehicle. Pressure value to prevent the penetration of air contaminated by the outside world. ...

AI Technical Summary

Problems solved by technology

At present, due to the influence of the airtightness of the vehicle body, some vehicles, such as trucks and light high-mobility vehicles, cannot adopt the overpressure nuclear, biological and chemical collective protection system, and other vehicles, such as tanks and armored vehicles, can only establish low overpressure. Generally, it is lower than 300Pa. At present, most vehicles such as heavy armored vehicles in my country and abroad have overpressure collective protection capabilities, but the overpressure is about 300Pa. Because the existing vehicle sealing method is through sealing strips, sealing strips It is easy to age and deform, resulting in a decrease in air tightness, and it is difficult to realize the overpressure collective protection capability, and the current overpressure collective protection system has not yet formed an automatic control system
