Abstract

The invention discloses an explosion-proof device for an oil tank of a motor vehicle. The device comprises the oil tank; a tank body covers the surface of the oil tank; a closed cavity is formed between the tank body and the oil tank; a controller and a first oxygen detection probe are arranged in the closed cavity; a plurality of solenoid valves are arranged on the surface of the oil tank in the closed cavity; a second oxygen detection probe is mounted in the oil tank; the controller is respectively connected with the first oxygen detection probe, the second oxygen detection probe and each solenoid valve; the tank body is communicated with a tail pipe of the vehicle through a pipeline. According to the device, exhaust containing extremely small oxygen can be guided into the closed cavity; the oxygen detection probes can monitor the concentration of oxygen in the oil tank and the closed cavity and feed back to the controller; then the controller controls the solenoid valves to be on and off to reduce the oxygen content in the oil tank, and as a result, the explosion-proof function of the oil tank of the motor vehicle can be achieved. The device is simple in structure, convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to an explosion-proof device, in particular to an explosion-proof device for the oil tank of a motor vehicle. Background technique [0002] With the development of the economy, motor vehicles have become a modern travel tool that people use every day. The fuel tank is a key part of a motor vehicle and usually contains a large amount of flammable substances. Therefore, the safety of the fuel tank, especially the explosion-proof problem, has become a very important issue. [0003] In order to realize the explosion-proof function of the fuel tank, the German product ECN (Explo Control) automobile fuel tank explosion-proof net adopts the following method: a porous material explosion-proof fuel-saving net is placed in the fuel tank. Within one second, the heat energy is quickly absorbed to keep the temperature in the fuel tank below the explosion point, so as to ensure that the fuel tank will not explode due to high temperature. Howe...
