Description

A bus fire extinguishing system

technical field

The utility model relates to a vehicle-mounted fire-fighting system for a bus, in particular to a bus fire-extinguishing system.

Background technique

As a very important means of transportation for people to travel in today's society, buses have the characteristics of large mobility and dense population. In recent years, spontaneous combustion accidents of buses have occurred frequently, often directly threatening the lives of passengers. Although the existing buses are equipped with portable fire extinguishers, once a fire breaks out in the compartment, especially in a crowded compartment, the passengers in the bus often panic and cannot play the role of the portable fire extinguisher in the chaotic situation in the bus, resulting in If the fire cannot be effectively controlled, it is easy to cause major accidents.

Utility model content

The purpose of the utility model is to provide a bus fire extinguishing system which is convenient to control and can quickly extinguish fire in crowded compartments, so as to overcome the deficiencies in the prior art.

The technical scheme of the utility model: a fire extinguishing system for a bus, including a compartment, a box body containing fire extinguishing materials is arranged on the top of the compartment, the box body is connected to the input end of the high-pressure pump through a pipeline, and the output end of the high-pressure pump passes through the pipeline Connect with the one-way valve, the one-way valve is connected with the main pipe through the pipeline, and there are at least 3 groups of nozzles connected in parallel on the main pipe;

The high-pressure pump is respectively connected to the vehicle-mounted power supply and the control switch arranged in the driver's cab through electric wires;

The nozzle is a smoke sensor nozzle, the nozzle is connected to the high-pressure pump through the wire, and the high-pressure pump is connected to the vehicle power supply through the wire;

The wires are wrapped with stainless steel tubes;

The fire extinguishing material is dry powder, foam or water.

Due to the adoption of the above technical scheme, the utility model is a vehicle-mounted fire extinguishing system. The box containing the fire extinguishing material is installed on the top of the compartment. When the bus encounters a fire accident, the driver can press the control switch in the cab to start it quickly. In this system, at this time, the fire extinguishing material is sprayed on every corner of the compartment through the nozzle, and the fire in the compartment is quickly extinguished. Moreover, the electric wires of the utility model are all covered with stainless steel tubes, so that the short circuit failure of the control circuit will not be caused by fire, and the reliability of the fire extinguishing system is improved. Therefore, the utility model not only has reliable control and convenience, but also has high fire extinguishing efficiency, and can realize rapid fire extinguishing in crowded compartments, and is a bus fire extinguishing device worthy of popularization.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Example

Referring to Fig. 1, a kind of bus fire extinguishing system of the present utility model comprises compartment 1, and the top of compartment 1 is provided with the box body 4 of splendid attire water, and box body 4 is connected with high-pressure pump 5 input ends by pipeline, and high-pressure pump 5 The output end of the valve is connected to the one-way valve 6 through the pipeline, and the one-way valve 6 is connected to the main pipe 3 through the pipeline. On the main pipe 3, five groups of shower heads 2 are connected in parallel to ensure that the shower heads 2 can spray water to the compartment 1 everywhere. The high-pressure pump 5 is connected to the vehicle-mounted power supply 9 and the control switch 8 arranged in the driver's cab through the wires 7; The control circuit of the system has failed. Therefore, when running into a fire in the compartment 1, the driver presses the control switch 8 in the driver's cab to start the high-pressure pump 5 with electricity, so that water is sprayed from each nozzle, and the fire in the car is quickly extinguished. Preferably, the sprinkler 2 is set as a smoke detector, and the nozzle 2 is connected to the high-pressure pump 5 through the wire 7, and the high-pressure pump 5 is connected to the vehicle power supply 9 through the wire 7. Therefore, when a fire occurs in the compartment 1, the smoke detector can automatically start the high-pressure pump. The pump 5 makes water spray out from each nozzle 2, and the fire in the car is quickly extinguished. Therefore, the fire extinguishing system of the utility model can be started by the driver, and can also be automatically started by the connection circuit of the smoke detector, and has the function of double insurance.
