[0034] The following Figures 1-5 describes the drone fire truck of the present utility model.
[0035] As Figure 1 and Figure 2 shown, in one embodiment, a drone fire truck includes a chassis 100, an attached girder 200, a foam fire extinguishing member 300, a tethered drone 400, and a drone flight control unit 500.
[0036] The chassis has a cab.
[0037] Preferably, the chassis 100 adopts German MAN chassis technology, or a Sinotruk chassis can also be used.
[0038] The attached girder 200 is installed on the chassis 100 and is used to connect the chassis 100 with the upper-mounted equipment.
[0039] Specifically, the upper-mounted equipment is various fire extinguishing and rescue tools and equipment equipped on the fire truck, such as steel ladders, water guns, water tanks, water pumps, first aid tools, and lighting equipment, etc.
[0040] The attached main beam 200 is installed between the chassis 100 and the upper equipment, and an elastic support and torque-free connection is adopted between the chassis 100 and the upper equipment, which greatly reduces the damage to the upper equipment when the chassis 100 is stressed and distorted, and improves the service life of the upper equipment.
[0041] The foam fire extinguishing component 300 has a CAFS system 310 and is installed on the attached main beam 200 for providing fire extinguishing foam.
[0042] Specifically, the CAFS system 310 is an RL-CAFS-GS500CD type micro-structured foam CAFS fire extinguishing system, which is driven by an independent engine, is suitable for extinguishing fires with 1%-6% A / B class foam liquid, and can be used in cooperation with the tethered unmanned aerial vehicle 400.
[0043] The tethered unmanned aerial vehicle 400 is installed at the output end of the foam fire extinguishing component 300 for spraying foam from high altitude.
[0044] Specifically, the tethered unmanned aerial vehicle 400 is connected to the outlet end of the foam fire extinguishing component 300 through a DN40 water hose, so that the foam can flow along the DN40 water hose to a higher area, thereby performing high-altitude fire extinguishing operations.
[0045] The unmanned aerial vehicle flight control unit 500 is installed on the attached main beam 200 and is connected to the tethered unmanned aerial vehicle 400 through a cable for controlling the tethered unmanned aerial vehicle 400 and providing electrical energy for the tethered unmanned aerial vehicle 400.
[0046] Specifically, when it is necessary to extinguish a fire in a high-altitude area, the tethered unmanned aerial vehicle 400 is connected to the foam fire extinguishing component 300. After the tethered unmanned aerial vehicle 400 reaches the specified height through the control of the unmanned aerial vehicle flight control unit 300, the CAFS system 310 is started to supply foam and water to the tethered unmanned aerial vehicle 400, so as to achieve the effect of spraying foam from high altitude for fire extinguishing.
[0047] The unmanned aerial vehicle fire truck in this embodiment is equipped with a CAFS system 310. By quickly generating a large amount of foam and generating foams with different mixing ratios, it can flexibly adjust the ratio of foam to water according to different fire conditions. This flexibility helps to reduce the usage amount of foam liquid, reduce the consumption of fire extinguishing agents during the fire extinguishing process, and cooperate the CAFS system 310 with the tethered unmanned aerial vehicle 400 to extinguish the fire in the fire area in time while reducing the close-range fire extinguishing of firefighters, effectively improving the safety and efficiency of the operation. Through the cable connection between the tethered unmanned aerial vehicle 400 and the unmanned aerial vehicle flight control unit 500, the effective flight time of the tethered unmanned aerial vehicle 400 in the air is extended, so as to achieve fire extinguishing in high-altitude areas.
[0048] Such as Figure 3 And Figure 4As shown, in one embodiment, the foam fire extinguishing component 300 includes a liquid storage tank 320 and a pump house 330. The pump house 330 is installed at one end of the attached girder 200 away from the cab, and the liquid storage tank 320 is installed between the pump house 330 and the cab.
[0049] Optionally, the top of the liquid storage tank 320 is configured with 4 × 150W LED lifting lighting lamps.
[0050] As Figure 5 shown, in one embodiment, the liquid storage tank 320 includes a water tank 322 and a foam tank 324, and the water tank 322 and the foam tank 324 are connected.
[0051] Preferably, the loading capacity of the water tank 322 is 8000L, and the loading capacity of the foam tank 324 is 500L. It can be used as an 8-ton foam fire truck in fire situations where high-altitude fire extinguishing is not required.
[0052] In this embodiment, the CAFS system includes a fire pump, a foam pump, an air compressor, a mixer unit, and an electrical control system. The electrical control system is connected to the fire pump, the foam pump, the air compressor, and the mixer unit through cables. The mixer unit is connected to the air compressor and the foam pump through pipelines respectively. The foam pump is connected to the foam tank 322 through a pipeline, and the fire pump is connected to the water tank 324 through a pipeline.
[0053] Specifically, the electrical control system 313 is used to control the operation and stop of devices such as the fire pump, the foam pump, and the air compressor. The mixer unit is connected to the air compressor to receive compressed air. The mixer unit is connected to the foam tank to transport the generated foam liquid into the foam tank 324 for storage. The foam pump is connected to the foam tank 324 through a pipeline to send the foam liquid to the tethered drone 400 or the nozzle. The fire pump is connected to the water tank 322 through a pipeline to supply water source to the foam system, so as to provide sufficient pressure to transport the water source into the foam system and mix it with the foam liquid, facilitating the control and adjustment of the foam liquid concentration in specific fire scenarios.
[0054] Preferably, the CAFS system 310 supports the injection of Class A and Class B foam liquids.
[0055] In this embodiment, the foam fire extinguishing component 300 further includes a fire cannon 340 (see Figure 4 ), and the fire cannon 340 is installed on the top of the pump house 330 and is connected to the pipeline outlet.
[0056] Preferably, the foam fire extinguishing component 300 further includes a fire hose, and the fire hose is detachably installed at the pipeline outlet end.
[0057] See Figure 5, the working principle of the CAFS system 310 is as follows: After the liquid storage tank 322 is filled with water and the foam tank 324 is filled with foam, start the CAFS system, open the pipeline valve of the fire fighting cannon 340, and perform the operation of spraying water or foam with the cannon.
[0058] For small fires only, close the pipeline valve of the fire fighting cannon 340, connect the fire fighting gun to the outlet end of the pipeline, and perform the fire extinguishing operation.
[0059] For high-rise building fires, close the pipeline valve of the fire fighting cannon 340, connect the input end of the tethered drone 400 to the outlet end of the pipeline, and perform the high-altitude fire extinguishing operation. During this process, if the foam liquid is insufficient, supplement the foam operation by connecting the external suction foam pipe to the inlet end of the pipeline.
[0060] When all the valves at the two groups of pipeline inlets are opened or only the pipeline valve of the fire fighting cannon 340 is opened, the system flow rate can reach 8 L / s.
[0061] In this embodiment, the drone flight control unit 500 includes a flight control room 510 and a drone cabin 520 (see Figure 4 ). The flight control room 510 is located at one end of the attached girder 200 adjacent to the cab, and the drone cabin 520 is located at one end of the attached girder 200 adjacent to the flight control room 510.
[0062] Optionally, the top and all around of the flight control room 510 are made of large-area bulletproof glass, providing a wide field of view for easy observation. Under the premise of ensuring safety, it enables the drone operator to closely control the drone for high-intelligent and simple operation, and has an interlock function to ensure operation safety, effectively preventing potential accidental injuries to the drone operator caused by falling debris in the air at the fire scene.
[0063] Preferably, a flight control operation platform is arranged in the flight control room 510. The flight control operation platform is provided with a mobile communication command system, which can collect and transmit video images of the fire scene through the network, and has the function of adjusting the heating and cooling air conditioners in the cab, as well as the remote control function for the fire fighting cannon 340 and the CAFS system 310.
[0064] In this embodiment, there is a drone landing platform 522 in the drone cabin 520 (see Figure 4 ). The drone landing platform 522 has an automatic lifting function and is used to park the tethered drone 400.
[0065] Among them, in the initial state, the drone landing platform 522 is located in the middle of the drone cabin 520.
[0066] It should be noted that the automatic lifting function of the drone landing platform 522 is a prior art, and the implementation principle thereof will not be elaborated here.
[0067] In this embodiment, the UAV flight control unit 500 further includes a tether box 530, a power distribution cabinet 540, and a generator 550 (see Figure 1 and Figure 2 ). The tether box 530 is installed below the UAV landing platform 522 and is connected to the tethered UAV 400 and the power distribution cabinet 540 through cables. The power distribution cabinet 540 is connected to the generator 550 through a cable. The power distribution cabinet 540 and the generator 550 are installed at the bottom of the UAV cabin 520.
[0068] Specifically, the model of the tethered UAV 400 is WK1900PRO, which is powered by the tether box 530 and can perform aerial fire extinguishing operations for a long time. The generator 550 is a 160KW double-bearing generator, which can output AC380V and AC220V alternating current through the power distribution cabinet 540. By equipping a 160KW double-bearing generator, the problem of multiple electrical appliances operating simultaneously can be solved.
[0069] Optionally, the tethered UAV 400 is equipped with a backup battery, which can achieve automatic return in case of power failure and automatic return in case of interruption of flight control signals, and has a safety protection function for leakage of the tether cable.
[0070] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0071] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
