Problems solved by technology

Although the current interior decorations of passenger cars use flame retardants, flame retardants are not equal to non-combustible, and once the flame retardants are burned, due to the relative difficulty of burning, smoke must be generated due to incomplete combustion. In general fires, Most of the deaths of personnel are due to choking on smoke and dust, and the proportion of real deaths from burning is relatively low.
Due to the characteristics of passenger cars, once a fire breaks out, it is impossible to quickly obtain common water, sand and other simple and effective fire extinguishing resources like public spaces. fire extinguisher, and it is impossible to transport the fire extinguisher to the fire area in time for fire extinguishing

Embodiment 1

[0040] See Figure 1-Figure 5 As shown, a fire protection system for the passenger compartment of a passenger car of the present invention includes:

[0041] A water mist spraying device, which includes a water storage tank 1 installed on a passenger car and containing a water agent 1, a first conveying pipe 3 and a first water mist nozzle 2, the first water mist nozzle 2 being arranged on the top of the inner side of the passenger car, The water storage tank 1 is connected to the water storage tank 1 through the first conveying pipe 3; the water storage tank 1 is connected with a power mechanism; here, there are multiple first water mist nozzles 2 arranged in a row and arranged at intervals along the long axis direction of the top surface of the passenger car. Above the aisle in the center of the top of the passenger car;

[0042] Fire extinguishing device, the fire extinguishing device includes a gas fire extinguishing mechanism, the gas fire extinguishing mechanism includes a fi...

Embodiment 2

[0053] See Figure 6-Figure 8 As shown (the parts of the gas fire extinguishing mechanism and power mechanism in the figure are the same as above, omitted), the passenger car passenger compartment fire extinguishing protection system of the present invention is different from the first embodiment: the water mist spraying device The water storage tank 1 is installed on the front side of the bottom of the passenger car, and its multiple first water mist nozzles 2 are divided into two rows. The two rows of first water mist nozzles 2 are arranged side by side along the long axis of the passenger car and are respectively located in the two rows of the passenger car. The upper position of the chair; the two rows of first water mist spray nozzles 2 are connected by an annular first conveying pipe 3, and the first conveying pipe 3 extends downward to connect to the water storage tank 1. Such as Figure 8 As shown, the Figure 8 The middle part C indicates the spraying range of the first...

Embodiment 3

[0055] See Figure 9-11 As shown (the parts of the gas fire extinguishing mechanism and the power mechanism in the figure are the same as above, omitted), the difference from the first embodiment is that there are three rows of seats inside the passenger car, and the water storage tank 1 of the water mist spray device is installed On the rear side of the bottom of the passenger car, the plurality of first water mist nozzles 2 are divided into two rows, and the two rows of first water mist nozzles 2 are respectively arranged side by side along the long axis of the passenger car and are respectively located between two rows of adjacent seats of the passenger car Above the aisle; the two rows of first water mist nozzles 2 are connected by a ring-shaped first conveying pipe 3, and the first conveying pipe 3 extends downward to connect to the water storage tank 1. Such as Picture 11 As shown, the Picture 11 The middle part D represents the spraying range of the first water mist noz...

The fire extinguishing protective system comprises a water mist spraying device, a fire extinguishing device and a starting device, wherein the water mist spraying device comprises a water storage tank, a first transmission pipeline and a first water mist nozzle; the first water mist nozzle is installed at the top part on the inner side of the bus and is connected with the water storage tank by virtue of the first transmission pipeline, the water storage tank is connected with a power mechanism; the fire extinguishing device comprises a water mist fire extinguishing mechanism and / or a gas fire extinguishing mechanism, wherein the water mist fire extinguishing mechanism comprises a second transmission pipeline and a second water mist nozzle, and the second water mist nozzle is installed at the bottom of the passenger compartment wall of the bus and is connected with the water storage tank or another water storage tank by virtue of the second transmission pipeline; the gas fire extinguishing mechanism comprises a fire extinguishing agent vessel, a fire extinguishing agent transmission pipeline and a fire extinguishing agent nozzle, wherein the fire extinguishing agent vessel is filled with a gas fire extinguishing agent, and the fire extinguishing agent nozzle is installed at the bottom of the passenger compartment wall of the bus and is connected with the fire extinguishing agent vessel by virtue of the fire extinguishing agent transmission pipeline; the starting device comprises a main controller, and the main controller is connected with a starting button and / or fire detector.

Description

Technical field [0001] The invention relates to a fire protection system, in particular to a fire protection system for a passenger compartment of a passenger car. Background technique [0002] In recent years, man-made arson incidents of buses or fire incidents caused by flammable and explosive materials have occurred nationwide, causing group injuries and seriously threatening the safety of citizens' lives and property. Because the passenger car itself belongs to a relatively closed and independent space during operation, its air mobility, crowd density, ease of evacuation, type of combustion, fire area, difficulty of extinguishing, etc. are all different from fixed public spaces. Once a fire or explosion occurs, the consequences can be disastrous. Although the current interior decorations of passenger cars use flame-retardant materials, flame-retardant materials do not mean incombustible. Once flame-retardant materials are burned, due to their relative difficulty in burning, ...
