DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0022] See also Figures 1 to 3As shown, a whole vehicle explosion-proof modification system includes: an explosion-proof electrical system, a diesel engine exhaust treatment system for treating exhaust gas, and an explosion-proof diesel engine protection device for monitoring the diesel engine;

[0023] The diesel engine exhaust treatment system is connected to an explosion-proof diesel engine protection device, the explosion-proof diesel engine protection device is connected to an explosion-proof electrical system, and the explosion-proof electrical system controls the diesel engine fuel cut-off and the vehicle power cut-off according to the monitoring result of the explosion-proof diesel engine protection device.

[0024] Furthermore, if Figure 1 As shown, the explosion-proof electrical system includes an explosion-proof battery 1, an explosion-proof control box 2, a generator 3 and a starter motor 4. The explosion-proof control box 2, the generator 3, the starter motor 4 and the explosion-proof diesel engine protection device are all connected to the explosion-proof battery 1 by flame-retardant cables. The explosion-proof battery 1 adopts a mining explosion-proof battery, and the ordinary battery of the operating machinery is converted into a lead-acid maintenance-free mining explosion-proof battery. All wiring ports are sealed with rubber expansion to avoid sparks that may be generated by the battery during operation or when a fault occurs, and to isolate it from the outside world. The starter motor control switch, the lighting control switch, etc. are encapsulated in the explosion-proof control box 2 to isolate the contact of each switch contact with the outside world. The generator 3 and the starter motor 4 are both sealed with glue to prevent the sparks generated during operation from contacting the outside world.

[0025] Furthermore, the explosion-proof electrical system also includes an explosion-proof signal lamp 5 for giving an alarm according to the monitoring result of the explosion-proof diesel engine protection device, and a flame-retardant cable is connected between the explosion-proof signal lamp 5 and the explosion-proof battery 1. 4. There are four explosion-proof signal lamps 5. The explosion-proof signal lamp 5 is used for giving an alarm, so as to facilitate timely transmission of information.

[0026] Furthermore, if Figure 2As shown, the diesel engine exhaust treatment system includes a first exhaust elbow 61, an exhaust bellows 62, a second exhaust elbow 63 and an exhaust treatment box 64 which are connected in sequence. The first exhaust elbow 61 is connected to the diesel engine flange, the exhaust treatment box 64 is fixed on the outside of the vehicle frame of the whole vehicle, and the exhaust treatment box 64 is connected to a water supply tank 65. The high-temperature exhaust gas discharged by the diesel engine passes through the first exhaust elbow 61, the exhaust bellows 62, the second exhaust elbow 63 and the exhaust treatment box 64 in sequence, and then is discharged into the atmosphere, thereby reducing the exhaust temperature at the outlet of the exhaust treatment box 64, eliminating the exhaust spark caused by the exhaust, and ensuring that the temperature of any surface of the diesel engine body is controlled within a safe range of ≤150°C and the exhaust temperature at the exhaust outlet is controlled within a safe range of ≤70°C. The exhaust bellows 62 flexibly connects the engine with the exhaust treatment box 64 fixed on the frame, reduces the vibration coupling between the engine and the frame, reduces the transmission of the engine vibration energy to the frame, reduces the noise, and increases the life of the rigid exhaust pipe. The main function of the exhaust gas treatment box 64 is to reduce the exhaust temperature, eliminate sparks in the exhaust gas and purify the exhaust gas. After the exhaust gas enters the exhaust gas treatment box 64, it passes through the internal structure to allow the exhaust gas and the cooling water in the exhaust gas treatment box to have sufficient contact area and contact time, so as to quickly reduce the exhaust temperature (≤70℃) and completely extinguish the sparks in the exhaust gas. At the same time, a large amount of carbon smoke and various harmful gases are dissolved in the water during this process, purifying the engine exhaust and achieving safe and clean emissions. In addition, in order to replenish water to the exhaust gas treatment box 64 in time, a water replenishment tank 65 ( Figure 2 The pipe connecting the water replenishment tank 65 and the exhaust gas treatment box 64 is not drawn in the figure) to replenish the water evaporated by high temperature in time. In the prior art, a fire-blocking fence is set at the exhaust outlet of the exhaust gas treatment box 64. When the exhaust gas passes through the explosion-proof fence, the remaining flame in the exhaust gas is extinguished again to prevent the flame from being transmitted to the outside air.

[0027] Furthermore, if Figure 3As shown, the explosion-proof diesel engine protection device includes a surface temperature sensor 71, an exhaust temperature sensor 72, a water level sensor 73, an explosion-proof controller 74 and a display screen 75. The surface temperature sensor 71, the exhaust temperature sensor 72 and the water level sensor 73 are all connected to the explosion-proof controller 74, and the explosion-proof controller 74 is connected to the display screen 75. The explosion-proof diesel engine protection device also includes a gas sensor 76, which is connected to the explosion-proof controller 74. The surface temperature sensor 71 is arranged on the diesel engine body, the exhaust temperature sensor 72 is arranged at the exhaust port of the exhaust gas treatment box 64, and the water level sensor 73 is arranged in the water supply tank 65. The explosion-proof diesel engine protection device is used to monitor indicators such as gas concentration, exhaust temperature, surface temperature, and water level of the water supply tank 65, and automatic protection parameters are set according to standard requirements. When any indicator exceeds the safety value, the explosion-proof electrical system automatically alarms to remind the driver to check and take measures immediately, and controls the diesel engine to automatically cut off oil, power off, shut down and stop within one minute. Specifically, when the temperature of the object being measured exceeds the set value, the LCD backlight turns on and the fault parameter keeps flashing. When the temperature value of the object being measured is lower than the set value, the device automatically returns to normal. When the water level of the water replenishment tank 65 is lower than the set value for 3 consecutive seconds, the device will sound an alarm, the LCD backlight turns on, and the fault parameter keeps flashing. When the water level rises above the alarm water level, the device automatically returns to normal. When the methane concentration in the working environment reaches the set value, the alarm automatically sounds, the LCD backlight turns on, and the fault parameter keeps flashing. At this time, you should stop the car in time and evacuate the tunnel quickly. After the tunnel is ventilated and the methane concentration drops below the safe value, enter the tunnel for operation.

[0028] Working principle: After the equipment is started and the explosion-proof diesel engine protection device is powered on, the temperature, water level, oil pressure and gas parameters are sampled and calculated through various sensors. The processing results are displayed through the display circuit and compared with the set value. If the detection parameter of a certain route exceeds the set value, an alarm is issued, the LCD display backlight is turned on, the over-value parameter flashes continuously, and a signal is fed back to the solenoid valve to control the operating machine to cut off the oil, power and flameout within 1 second.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
