At the same time, the foam liquid in the foam liquid delivery pipeline flows downward based on its own gravitational potential energy, so that negative pressure is generated in the foam infusion pipeline, the flow rate of the foam liquid in the foam infusion pipeline is increased, and the unit volume output efficiency of the foam generator is improved. In addition, the lifting structure can be connected to the external structure to realize the lifting of the fire extinguishing device.

[0033] Example:

[0034] An airborne hovering static pressure potential energy foam fire extinguishing device, such as Figure 1 As shown, it comprises: a foam liquid storage device 1, a foam liquid releaser, a foam liquid delivery pipeline 4 and a foam generator 5; a cavity for storing foam liquid is provided inside the foam liquid storage device 1; the foam liquid storage device 1, the foam liquid releaser, the foam liquid delivery pipeline 4 and the foam generator 5 are connected in sequence from top to bottom; a hoisting structure is provided at the upper end of the foam liquid storage device 1. When the foam liquid is filled in the foam liquid storage device 1, the foam liquid releaser and the foam liquid delivery pipeline 4, the gas pressure in the foam liquid delivery pipeline 4 is less than the atmospheric pressure.

[0035] The foam liquid storage device 1 includes a foam liquid storage tank body; the foam liquid storage tank body is a columnar hollow structure, and an inlet is provided at the upper end thereof, and an outlet is provided at the lower end thereof; the outlet of the foam liquid storage tank body is connected to the foam liquid releaser. In this embodiment, the hoisting structure at the upper end of the foam liquid storage tank body can be selected as a connecting seat connected to an external structure. In this embodiment, a connecting seat for connecting with a rope is selected, and a plurality of protrusions are provided on the connecting seat, and a through hole is provided on the protrusion. The rope provided on the external structure is tied in the through hole of the protrusion to hoist the fire extinguishing device.

[0036] The foam liquid releaser includes a gas-driven bottle 2 and a pneumatic pump 3; the upper end of the pneumatic pump 3 is provided with a first inlet and a second inlet, and the lower end is provided with an outlet; the first inlet of the pneumatic pump 3 is connected to the foam liquid storage device 1; the second inlet of the pneumatic pump 3 is connected to the gas-driven bottle 2; the outlet of the pneumatic pump 3 is connected to the foam liquid delivery pipeline 4. In this embodiment, the first inlet is arranged at the middle of the upper end of the pneumatic pump 3, so as to be conveniently connected to the foam liquid storage tank; the second inlet is opened at the upper end of the side wall of the pneumatic pump 3, and the outlet of the gas-driven bottle 2 is connected to the second inlet.

[0037] Both ends of the foam liquid delivery pipeline 4 are provided with flanges; both ends of the foam liquid delivery pipeline 4 are respectively fixedly connected to the foam liquid releaser and the foam generator 5 through the flanges. In this embodiment, the flanges at both ends of the foam liquid delivery pipeline 4 are fixedly connected to the outlet of the pneumatic pump 3 and the foam generator 5 through bolts. In order to increase the sealing performance, sealing gaskets are provided between the foam liquid delivery pipeline 4 and the foam liquid releaser, and between the foam liquid delivery pipeline 4 and the foam generator 5.

[0038] In this embodiment, the foam liquid delivery pipeline 4 is a flexible pipe. In this embodiment, the length of the foam liquid delivery pipeline 4 is 10 meters to 50 meters.

[0039] The device further includes a foam outlet 6 of an annular structure; an inlet is provided at the upper end of the foam generator 5 and is connected to the foam liquid delivery pipeline 4; an outlet is provided at the lower end of the foam generator 5, and the foam outlet 6 is fixedly installed at the outlet of the foam generator 5.

The pneumatic pump 3 generates mechanical energy to output the foam-like foaming liquid. The height difference between the pneumatic pump 3 and the foam generator 5 is used to increase the gravitational potential energy of the foam-like foaming liquid, and the downward impact pressure in the foam liquid delivery pipeline 4 hits the inside of the foam generator 5.

[0042] like Figure 2As shown, first, the airborne hovering static pressure potential energy foam fire extinguishing device is connected to the lower end of the aircraft through a lifting structure, so that the aircraft lifts the airborne hovering static pressure potential energy foam fire extinguishing device; secondly, it flies to the sky above the fire scene, with the fire extinguishing device located about 70 meters above the fire scene, and flies at a uniform speed parallel to the unburned fire line; then, before flying to the release point, after turning on the pneumatic pump 3, the foam liquid delivery pipeline 4 freely falls downward and unfolds 40 meters, and the valve of the gas drive bottle 2 is automatically opened at the same time; finally, the foam liquid in the foam liquid storage tank will hit the inside of the foam generator 5 with the pressure of the downward impact of the free fall motion in the foam liquid delivery pipeline 4, thereby driving the foam generator 5 to quickly output a large amount of fine foam for isolation and fire extinguishing.
