Fireproof unmanned aerial vehicle system for fire site surveying

Abstract

The invention relates to the field of flight equipment and discloses a fireproof unmanned aerial vehicle system for fire site surveying. The fireproof unmanned aerial vehicle system comprises an unmanned aerial vehicle and a fine controller controlling the unmanned aerial vehicle in a wireless communication mode. Electronic speed regulators are installed on corresponding arms respectively, and semiconductor chilling plates are arranged between the electronic speed regulators and the arms. The fireproof unmanned aerial vehicle system further comprises two or more signal bridging devices arranged independently and used for carrying out mutual bridging and realizing wireless bridging between the unmanned aerial vehicle and the fine controller. According to the fireproof unmanned aerial vehicle system, the whole is made of fireproof material resistant to high temperature, and therefore the unmanned aerial vehicle can be operated normally and carry out surveying after entering a high-temperature fire site; the semiconductor chilling plates are arranged for dissipating heat of the electronic speed regulators, and therefore the temperature of the electronic speed regulators does not exceed the highest limit temperature even in the fire site; the multiple signal bridging devices are arranged and are used for bridging controlling signals and data signals, and therefore the unmanned aerial vehicle and the fine controller can realize continuous communication.

Description

technical field [0001] The invention relates to the field of flight equipment, in particular to an unmanned aerial vehicle, in particular to a fire prevention unmanned aerial vehicle system used for fire scene survey. Background technique [0002] At present, when a fire breaks out, fire trucks are dispatched to fight the fire, but the limitations of fire trucks are very large. For example, if a fire breaks out in a high-rise building, the height of the ladder and fire water cannon spraying water is limited, and there will be situations where it is impossible to rescue and cause major property damage. Loss and casualties, if the firefighters enter the building to rescue people or put out the fire, it will endanger the life safety of the firefighters, and the rescue speed is slow in addition. Another example is the old urban areas of some cities, where the lanes are narrow and the traffic is jammed. When a fire breaks out, fire trucks often cannot get in and cannot arrive at ...

Problems solved by technology

[0004] The above-mentioned high-rise police fire-fighting drone also has the following defects: 1) The drone is only used for high-rise fire-fighting, and the drone with this structure cannot enter the fire scene at all, but simply rises to the outside of the corresponding floor, and then After aiming at the fire scene and then launching the fire extinguishing bomb, it cannot enter the fire scene for survey, nor can it transmit any real-time parameters. It has no effect on the survey of the fire scene. In the end, firefighters still need to enter the building to rescue people or fire ;2) The UAV is not equipped with any fire-proof structure, so it cannot enter the fire scene, and it is not equipped with any structure that can effectively cool down the electronic governor. During the fire-fighting process, the temperature of the UAV will increase sharply, and The heat inside the UAV will slowly accumulate and cannot dissipate any heat to the outside. When the temperature of the electronic governor of the UAV reaches the maximum rated temperature, the UAV cannot continue to fly. 3) The UAV can only go up to the outside of the corresponding floor to extinguish the fire. When it enters the floor, the UAV will be affected by barriers such as walls and cannot transmit control signals normally. , causing the drone to lose control

However, in a real fire scene, the UAVs involved in fire fighting are rarely made into a structure with an engine, and they all use a rotor lift structure. The UAV with an engine structure is suitable for a relatively wide environment, and its volume is large , in the fire scene, the internal space is extremely narrow, and, assuming that the UAV with the rotor lift structure is also cooled by the cooling channel, this cooling method is impossible to achieve the cooling effect in the fire scene, because the fire scene The temperature in the fire scene is extremely high, and the scene is full of high-temperature hot air. The air flow through this air cooling method is hot air. The hot air does not have any cooling effect on the drone in the fire scene. At the same time, the air flow in the fire scene is unstable. , seriously affecting the normal operation of the UAV

[0006] The domestic invention patent with the patent publication number "CN103017391A" discloses a volumetric compressor onboard evaporative circulation system under large overload conditions. effect, to achieve the purpose of cooling, this cooling method can achieve a good cooling effect, and the cooling process is continuous, ensuring that the drone can continue to operate, however, the overall volume of this cooling structure is large, and it needs to be equipped with a complete A set of refrigeration systems, including compressors, coolers, heat exchangers, evaporators, gas-liquid separators, etc. At the same time, the refrigeration system needs to consume a lot of electricity when it is working, wasting more energy; Unable to deal with larger drones, especially when the internal environment of the fire scene is not clear, it will affect its flight operation. In addition, the refrigeration system will consume a lot of power, especially in the high temperature fire scene, the power consumption will be even greater , the power supply of the UAV also needs to supply power to various cameras and other electronic equipment. Therefore, although the UAV equipped with this refrigeration system has a good cooling effect, it cannot guarantee the continuous cruising time, and it cannot achieve the purpose of surveying at all.
