Background

As the electric cabinet, the air-conditioning cabinet and the like on the motor train unit are used as key components of the motor train unit, the internal equipment is complex and important, the space is narrow, once a fire disaster occurs, if the fire disaster is not stopped in time, the consequence is unreasonable, the situation that the fire disaster in one cabinet body reaches a nearby cabinet body often occurs, the situation that the fire disaster occurs in the connected cabinet body after the fire disaster occurs in the cabinet body which sends an alarm in reality occurs, the fire disaster condition is judged manually after the fire disaster alarm of the motor train unit, the fire extinguisher is opened for fire extinguishment, the time from the fire disaster alarm to the response is long, and the fire fighting time is delayed. Aiming at the situation, the active fire fighting device is added in the electric cabinet area of the motor train unit, and if the active fire fighting device is added in each cabinet, factors such as lack of space in the cabinet, inconvenience in installation and the like exist, and the active fire fighting device cannot be adopted in practice.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a many cabinets body linkage fire control unit, a plurality of cabinets body fire control linkage, the reaction is rapid, reducible loss, guarantee passenger's life and property safety and the installation needs the space little.

In order to realize the above utility model, the utility model provides a many cabinets body linkage fire control unit, its characterized in that: the fire fighting system comprises an active fire fighting box, a medicament sprayer, a smoke and temperature compound fire detector, a flame detector, an active fire fighting host, a smoke and fire alarm system host and a train network management system, wherein the active fire fighting box is arranged in one of the cabinet bodies of the linkage fire fighting system, a medicament tank, a medicament control valve and a pressure sensor are arranged at the outlet of the medicament tank, the medicament tank is connected with the sprayers arranged in the cabinet body and the linkage cabinet body through pipelines, the pressure sensor and the medicament control valve in the active fire fighting box are connected with the active fire fighting host, the smoke and temperature compound fire detector and the flame detector are respectively arranged on the upper part of each cabinet body and are connected with the smoke and fire alarm system host through a communication network, the active fire fighting host and the smoke and fire alarm system host are connected with the train network management system through the communication network, and collected information is transmitted to the train network management system, and executes the command of the train network management system. When a fire disaster happens, the plurality of cabinet bodies are in fire-fighting linkage, alarm information is timely transmitted to the train network management system, a response is timely made, and the initial fire disaster is quickly suppressed.

The outlet of the medicament tank is provided with a temperature sensing bulb which can automatically break according to the temperature in the cabinet to open the medicament control valve, when the temperature in the cabinet is higher than a set value, the temperature sensing bulb breaks to automatically open the medicament control valve, and the medicament is sprayed out from the spray head.

The shower nozzle sets up one or more according to the interior components and parts distribution position of cabinet, device density, the calorific capacity of device and the wiring distribution condition of cable, and a plurality of regional shower nozzles open simultaneously when taking place the conflagration, diversified protection.

The composite fire detector and the flame detector are arranged in the middle of the top of the cabinet body, and are arranged in the middle of the top of the cabinet body to find out a fire in time according to the upward emission characteristics of smoke and heat.

The existing areas of the motor train unit air-conditioning cabinet, the electrical cabinet and the like have fire detection means, but once a fire occurs, manual fire extinguishing is needed, and the vehicles cannot take fire extinguishing measures in time, so that the fire hazard is eliminated. In order to further improve the fireproof and fire extinguishing performance of the vehicle, a multi-cabinet linkage fire extinguishing system is added in a multi-cabinet area of the motor train unit. If the conflagration breaks out, utilize remote control to start many cabinets body linkage fire control unit, the novel fire extinguishing agent of internal automatic blowout of cabinet puts out a fire to the initial stage conflagration, strives for valuable time of putting out a fire, guarantees driving safety. In addition, the multi-cabinet linkage fire-fighting system can spray fire-extinguishing agents to the multiple cabinets simultaneously by only installing one active fire-fighting box in one cabinet, occupies small space and does not occupy other spaces of a motor train unit train.
