[0002] A diesel engine is an engine that burns diesel to release energy. The advantages of a diesel engine are high torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also goes through four strokes: intake, compression, power, and exhaust. An explosion-proof device refers to a device that uses structural isolation measures to isolate a circuit from the surrounding environment, so that the heat generated by the circuit during normal operation and the electric sparks and high temperatures formed in a fault state are limited within a sealed casing to prevent ignition of flammable and explosive media around the outside of the equipment casing. With the development of industry, various explosion-proof devices have emerged, such as a cable explosion-proof device for diesel engines.
[0003] At present, the cable explosion-proof devices for diesel engines on the market are mainly modified for circuit isolation. The existing cable explosion-proof devices are generally composed of diesel engines, cables and flame-retardant materials. The cables are wrapped with flame-retardant materials at the junction of the cables and diesel engines to prevent accidental burning of the cables. However, the existing cable explosion-proof devices can only passively retard after burning, and cannot monitor the external conditions of the cables and temporarily use fire-extinguishing spray to block the flames in time. Therefore, a diesel engine cable explosion-proof device is proposed, which can monitor the power supply of the cables, temporarily cut off the power and use fire-extinguishing spray to block the flames.

When the diesel engine body is started and powered on, the internal circuit of the controller inside the insulating frame is connected to the cable body, and the voltage inside the cable body is always displayed through a voltmeter. When the voltage is abnormal, the voltage exceeds the standard range, and the controller uses a breaker to cut off the power.
