Description
Technical Field
The utility model relates to a rail vehicle carriage fire extinguishing systems relates to the conflagration.
Background
The subway train fire is the most complicated type of subway fire, and because the subway train carriage is a relatively closed environment and is positioned underground, when a fire breaks out in the running process of the train, people are difficult to evacuate, and fire fighters are difficult to rescue. The traditional subway train fire-fighting facilities mainly adopt a passive fire prevention diffusion mode of fire pre-alarming, and have limited action under the condition of large fire or fast spreading.
Through the discovery of retrieval, chinese utility model patent CN 201101842Y discloses a thin water smoke fire extinguishing control device in subway carriage, and it includes thin water smoke fire extinguishing control system, respectively sets up a thin water smoke fire extinguishing control system in each section of subway carriage, has a subway driver control operating system to connect the thin water smoke fire extinguishing system that sets up in each section of subway carriage. The fire extinguishing system adopts a bottle group type water mist fire extinguishing system, uses compressed gas in a high-pressure gas bottle as a power source to push fire extinguishing agent (water) to be sprayed out at a certain pressure, thereby achieving the purpose of fire extinguishing.
At present, a bottle group type water mist fire extinguishing system is widely used in the international rail transit industry, and the method comprises a gas storage bottle, a liquid storage tank, a pipe network, a spray head, a controller, a fire alarm probe, a camera, the spray head and the like. The controller is connected with a switch electromagnetic valve on the spray head and a cylinder head valve on the gas storage cylinder through a lead, and when a fire disaster happens, the fire is extinguished through the spray head in the carriage. The bottle group type water mist fire extinguishing system has the defects of long response time, unstable working pressure, heavier weight, potential safety hazard and the like, so that the system has poor use effect on a train. The core technology of the bottle group type water mist fire extinguishing system is completely mastered in European and American companies, the manufacturing cost is high, and the bottle group type water mist fire extinguishing system cannot completely meet the development trend of rail transit in China.
Therefore, a set of high-pressure water mist system based on a pump set is designed by combining the actual situation of the metro vehicle, which is helpful for quickly controlling the fire, striving for rescue time and timely evacuating the masses when a fire disaster occurs.

The numbers in the figures are as follows:
HMI-monitor display; b-pump group box; an L-line; z-monitoring host; k-pump unit case solenoid valve; a T-flame detector; s-camera; p-water mist spray head.
Detailed Description
The following explains an embodiment of the present invention with reference to the drawings by taking a 6-formation type B train as an example.
As shown in fig. 1, the fire extinguishing system for railway vehicle carriage is characterized in that: the system comprises a monitoring display HMI positioned in a cab, a pump set box B positioned in a head car and a pipeline L penetrating through the whole car, wherein each car is provided with a monitoring host Z, a pump set box electromagnetic valve K, a flame detector T installed on a top plate of a passenger room, a camera S and a water mist spray head P; the end of a pipeline L penetrating through the whole vehicle is connected with a pump set box B of a head vehicle, each vehicle is provided with a branch pipe connected with the pipeline L, the electromagnetic valve K of the pump set box is installed at the upstream end of the branch pipe, and the water mist spray head P is arranged at the tail end of the branch pipe. The entire system power supply DC110V, the network components of the full train are connected using industrial ethernet.
The specific mounting positions of the main components of the embodiment are as follows:
and a monitoring host Z: the electric cabinet is arranged in the 2-position end electric cabinet of each carriage;
pump set case B: a body chassis mounted to the head car;
pump set case solenoid valve K: a body chassis mounted to each vehicle;
a flame detector T: two carriages are symmetrically arranged on a top plate in a passenger room of each carriage;
a camera S: two carriages are symmetrically arranged on the top plate in the passenger room of each carriage.
Monitoring display HMI: is arranged on a driver platform.
When the system detects that flame occurs in the vehicle in normal operation, the flame detector transmits an alarm signal to the cab, an audio alarm is sent out to remind a driver of paying attention, and meanwhile, video monitoring of a corresponding area is displayed on a computer screen, so that the driver can judge whether the system needs to be started. Once started, the nozzles in the corresponding areas spray high-pressure water mist, the ambient temperature is reduced, and oxygen around the flame is isolated, so that the spread of fire is controlled, and a fire source is gradually extinguished.
The water mist safety system has the functions of flame detection, video monitoring, looped network redundancy, water pressure monitoring, water temperature control, liquid level monitoring, overtime operation protection, misoperation prevention, fault diagnosis and the like.
When a fire disaster occurs in the passenger room, the system is triggered, and a driver judges whether to trigger the high-pressure water mist system to extinguish the fire according to the corresponding monitoring video displayed on the touch screen computer.
When the high-pressure water mist system works, the maximum power is 11kW, the working voltage is DC110V, and the working time is 4 minutes.
When the train has high voltage input and the two chargers work normally, the chargers supply power to the whole system. When one charger of the train has a fault, the emergency brake button is pressed by a driver, and the system is powered by the storage battery instead.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
