Description
Technical Field
The invention belongs to the technical field of fire fighting of fire trucks, and particularly relates to an intelligent self-protection system for a turbofan monitor fire truck.
Background
The turbofan fire truck is an important device for fighting fire, and is widely applied to the field of fire fighting. The turbofan fire engine has the capability of simultaneously spraying two fire extinguishing media, namely foam and water mist. Tests prove that compared with a single fire extinguishing medium, the fire extinguishing effect of the fire extinguishing medium formed by mixing the foam and the water mist is stronger. Although the fire extinguishing capability of the turbofan fire engine is stronger, in the face of complex scenes such as a substation fire field and the like, when the fire is burned to a violent stage, the fire engine is damaged by heat radiation generated by combustion. Due to the thermal expansion factor and the inherent limitation of poor heat resistance of the material, especially for equipment such as tires, the tires are burnt and broken due to the over-high temperature.
The self-protection system of the existing turbofan fire engine is judged on site by an operator and is started in a manual mode. However, in a stressful fire-fighting environment, it is often difficult for a fire fighter to attend to. And if the time for starting the self-protection system in a manual mode is not suitable, a large amount of fire-fighting water can be used for the self-protection system of the turbofan monitor fire truck. The turbofan cannon fire truck has a limited capacity of a water tank, and if the subsequent fire-fighting water supply fails to follow up in time, the pressure of fire extinguishing work can be increased.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The self-protection system of the existing turbofan fire engine is judged on site by an operator and is started in a manual mode. However, under a nervous fire-extinguishing environment, a fireman is often difficult to take care of, so that the self-protection of the turbofan fire truck is not timely, and the vehicle is damaged. And if the self-protection system is started in a manual mode too early, a large amount of fire-fighting water can be used for the self-protection system of the turbofan monitor fire truck. The self-protection system of the existing turbofan fire engine also has the problem of fixed nozzle flow, thereby causing the waste of water resources and increasing the water pressure.
In order to solve the above technical problem, as shown in fig. 1, the present embodiment provides an intelligent self-protection system for a turbofan fire fighting truck. This an intelligent self preservation system for turbofan big gun fire engine includes fire engine 10, intelligent monitoring system 20, temperature sensor 30, water tank 80, spray pump 40, self preservation pipeline 50 and self preservation nozzle 60, and fire engine 10 includes automobile body 11 and wheel 12, and intelligent monitoring system 20, temperature sensor 30, water tank 80 and self preservation pipeline 50 are installed in automobile body 11, and spray pump 40 installs in self preservation pipeline 50 and self preservation pipeline 50's water inlet and water tank 80 intercommunication.
The self-protection nozzle 60 is installed at the water outlet of the self-protection pipeline 50 and faces the wheel 12, and the intelligent monitoring system 20 is used for receiving a wheel 12 region temperature signal sent by the temperature sensor 30, controlling the spray pump 40 to be turned on according to the temperature signal and controlling the self-protection nozzle 60 to spray a cooling medium to the wheel 12.
Specifically, the temperature sensor 30 is mounted on the housing of the vehicle body 11 above each set of wheels 12.
When the fire fighting vehicle 10 receives a fire fighting command and reaches a specified fire fighting point, the fire fighting vehicle 10 itself is easily damaged by high temperature, particularly the wheels 12, to start spraying for fire fighting.
The intelligent self-protection system for the turbofan monitor fire engine of the embodiment has the beneficial effects that: upon arrival at the fire suppression site, the temperature sensors 30 sense the temperature near the wheels 12 and communicate the temperature information to the intelligent monitoring system 20. When the intelligent monitoring system 20 judges that the temperature near the wheels 12 reaches the preset dangerous high temperature, the spray water pump 40 is controlled to be opened and the self-protection nozzle 60 is controlled to spray a cooling medium to the wheels 12, so that the wheels 12 are cooled to protect the wheels 12. The whole self-protection work is automatically completed through the intelligent monitoring system 20, and manual starting is not needed. And for manual start, the spraying time of the self-protection nozzle 60 can be more accurately judged by the temperature sensor 30 in cooperation with the intelligent monitoring system 20 in the embodiment, so that too early or too late spraying is avoided, waste of water is avoided, and the situation that the wheels 12 cannot be protected in time is avoided. The intelligent self-protection system of the turbofan cannon fire engine of the embodiment is intelligent and efficient.
Preferably, the intelligent self-protection system for the turbofan cannon fire engine further comprises a fire extinguishing water pump for fire extinguishing in a fire extinguishing site, and the fire extinguishing water pump and the spray water pump 40 are communicated to the same water tank 80. The spray water pump 40 is a small water pump.
The self-service water of the present embodiment is water in a water tank 80 that the fire engine 10 is originally equipped with. If the self-protection water is more, the water consumption for fire extinguishing is reduced. Therefore, the advantage of the fire engine 10 can be increased by using less self-protection water, which is particularly important for fire safety. Specifically, as shown in fig. 2, a main electric valve 90 or a pneumatic valve is provided between the spray water pump 40 and the water tank 80. The self-protection function can be independently started when the fire-extinguishing water pump does not work.
Preferably, the intelligent self-protection system for the turbofan monitor fire truck further comprises a power ball valve 70 installed on the self-protection pipeline 50, wherein the power ball valve 70 is used for being controlled by the intelligent monitoring system 20 to control the spraying amount of the self-protection nozzle 60. The electric ball valve 70 controls the spraying amount of the self-protection nozzle 60 according to the temperature signal transmitted by the temperature sensor 30. Specifically, the electric ball valve 70 is powered by the onboard power supply of the fire truck 10 and is installed at the water outlet section of the self-protection pipe 50. When the temperature signal of the temperature sensor 30 reaches a dangerous value and is high, the electric ball valve 70 controls the self-protection nozzle 60 to increase the spraying amount. When the temperature signal of the temperature sensor 30 reaches a dangerous value and is low, the electric ball valve 70 can control the self-protection nozzle 60 to reduce the spraying amount. The amount of spray from the self-protection nozzle 60 of the present embodiment is adjustable according to the temperature value, thereby saving water in the water tank 80. Allowing more water to be used to extinguish the fire.
Specifically, when the temperature signal of the temperature sensor 30 reaches a preset dangerous value, the intelligent monitoring system 20 sends an opening instruction to the electric ball valve 70, the electric ball valve 70 is started, the water outlet valve is opened, and the self-protection nozzle 60 works.
Preferably, the intelligent monitoring system 20 controls the self-protection nozzle 60 to spray the cooling medium to the wheel 12 when the temperature signal of the temperature sensor 30 reaches a preset high temperature or higher. The intelligent monitoring system 20 controls the self-protection nozzle 60 to stop working when the temperature signal of the temperature sensor 30 reaches a preset temperature.
Preferably, the number of the temperature sensors 30 and the self-protection nozzles 60 is more than two, and the self-protection nozzles 60 are correspondingly arranged in a team, and the intelligent monitoring system 20 receives the temperature signal of the temperature sensor 30 and controls the self-protection nozzles 60 corresponding to the temperature sensor 30 to work. Specifically, the fire engine 10 of the present embodiment includes six sets of wheels 12. Accordingly, the number of the temperature sensors 30 and the self-protection nozzles 60 may be set to six. One temperature sensor 30 and self-protection nozzle 60 are provided near each set of wheels 12. The temperature sensor 30 is provided on the vehicle body 11 in the vicinity of the wheel 12, and senses the temperature in the vicinity of the wheel 12. When a single wheel 12 is in a high-temperature environment, the temperature signal sensed by the temperature sensor 30 corresponding to the wheel 12 reaches a preset dangerous value, and the intelligent monitoring system 20 controls the self-protection nozzle 60 corresponding to the wheel 12 to spray the cooling medium to the wheel 12. That is, the present embodiment can individually protect each wheel 12, thereby saving water.
In another embodiment, as shown in fig. 2, the electric ball valves 70 of the present embodiment are four in number. The front two wheels 12 are each provided with an electric ball valve 70. The wheels 12 on the same side of the rear wheels 12 are closer together, thereby sharing one electric ball valve 70. The number of the temperature sensors 30 is also four. The front two wheels 12 are each provided with a temperature sensor 30. The wheels 12 on the same side of the rear wheels 12 are closer together, thereby sharing one temperature sensor 30, and saving components.
At a fire-extinguishing site, when the temperature of one side of the fire fighting truck 10 is high, the intelligent monitoring system 20 can control the self-protection nozzles 60 on one side of the fire fighting truck 10 to work simultaneously. While the temperature of the other side is lower and the self-protection nozzle 60 of the other side is in a non-working state, thereby saving water.
Preferably, the self-protecting nozzle 60 is a self-protecting atomizing nozzle, thereby enabling more uniform and water-saving spraying.
In further embodiments, the temperature sensor 30 continuously measures the temperature near the wheel 12. The intelligent monitoring system 20 sends out an alarm signal when the temperature signal of the temperature sensor 30 reaches a preset dangerous value or more, and simultaneously controls the corresponding electric ball valve 70 to start, and opens the water outlet valve, so that the self-protection nozzle 60 works. If the temperature continues to rise at this time, the amount of water sprayed is increased by the electric ball valve 70. If the temperature does not rise and is still greater than the dangerous value, the current amount of water sprayed may continue to be maintained.
When the temperature signal sensed by the temperature sensor 30 is lower than the preset dangerous value, the intelligent monitoring system 20 controls the corresponding electric ball valve 70 to close, the self-protection nozzle 60 stops working, and the alarm signal stops.
The driver and the operator can acquire the ambient temperature information of the fire fighting truck 10 through the intelligent monitoring system 20 and the temperature sensor 30.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
