Lifesaving device used for passenger car fallen into water

Abstract

The invention discloses a lifesaving device used for a passenger car fallen into water. The device comprises a gas chamber I, a gas chamber II, a gas chamber III, a gas chamber IV, a normally-open two-position two-way electromagnetic valve I, a normally-open two-position two-way electromagnetic valve II, a normally-open two-position two-way electromagnetic valve III, a normally-open two-position two-way electromagnetic valve IV, a normally-closed two-position two-way electromagnetic valve and a gas pump, wherein the gas chamber I, the gas chamber II, the gas chamber III, and the gas chamber IVare arranged on a passenger car chassis and are arranged at the four corners of the passenger car chassis correspondingly. The device has the beneficial effects that the four independent gas chambersare adopted to ensure that the passenger car can float on the water surface to wait for rescue after drowning, and meanwhile, gas bags of the four gas chambers can adjust the state of a vehicle bodyat the proper time in a step-by-step control mode, so that the survival rate generated after the passenger car is drowning is greatly increased, unnecessary personal casualties are reduced, the rescueeffective time is prolonged, and the rescue difficulty is reduced. Moreover, the device can be repaired or maintained in a grading mode, so that the maintenance cost is low, and the maintainability requirements are met.

Description

technical field [0001] The invention relates to a lifesaving device, in particular to a passenger car falling into water lifesaving device, which belongs to the application technical field of passenger car falling into water lifesaving device. Background technique [0002] As one of the indispensable means of transportation in modern people's life, passenger cars, especially buses, have brought a lot of convenience to people's lives, but in recent years, bus accidents have attracted people's attention. It is not difficult to find that when the passenger car fell into the water, the door could not be opened at all due to the water pressure, and the vehicle continued to sink, eventually causing the occupants to drown and die; therefore, the passenger car can be kept floating on the water surface after the passenger car fell into the water , so that passengers can have enough time to save themselves or wait for rescue is the problem that needs to be solved at present.
