Embodiment 1

[0032] see Figure 1-3, an energy-saving fire-fighting UAV controlled by water energy, including a multi-rotor lift 1, a three-axis pan-tilt 2 and a water spray gun 3, the multi-rotor lift 1 can use a common four-rotor lifting mechanism, and the three-axis pan-tilt 2 is a common multi-angle rotation control device. The water spray gun 3 is installed at the bottom of the three-axis head 2, and the water spray position and angle of the water spray gun 3 can be controlled by remotely controlling the three-axis head 2; wherein the water spray gun 3 Including water spray pipe 31 and wind force device 32, water spray pipe 31 is used for spraying water flow outwards, the effect of wind force device 32 is to generate air flow, and the reaction force produced by wind force device 32 due to air flow is used to offset or partially offset water spray pipe 31 spray. The reaction force produced by water; the specific connection method is as follows: the water spray pipe 31 includes an outer...

Embodiment 2

[0034] see Figure 5 with Image 6 , The difference with Embodiment 1 is that the water spray gun 3 also includes a piston disc 33 and a spring 34, the piston disc 33 and the spring 34 are located in the outer tube 311 and on one side of the inner tube 312, the inner wall of the piston disc 33 and the outer tube 311 Sliding and sealing fit, the spring 34 is located on one side of the piston disc 33 and is in contact with the end of the outer tube 311 close to the wind power device 32, the side of the piston disc 33 away from the connecting plate 3121 is fixedly connected with the drive shaft 331, and the drive shaft 331 One end runs through one end of the outer tube 311 and extends to the outside. The wind power device 32 is rotatably connected with an intermediate transmission mechanism 322. The blade plate 3212 on the wind impeller 321 is a swing structure. The plane where the swing track is coincident with the axis of the wheel shaft 3211 is located at the 321 The upper bl...

Embodiment 3

[0036] see Figure 4 , a further description relative to Embodiment 1 is that the two side walls in the axial direction of the inner pipe 312 in the water inlet hole 4 are fixedly connected with a rectangular plate 41, and the axis of the water inlet pipe 3111 is eccentrically distributed relative to the axis of the outer pipe 311. Since the inner pipe 312 and the outer pipe 311 rotate and cooperate, when the water body enters the outer pipe 311 through the water inlet pipe 3111, it is to generate a thrust on the part of the rectangular plate 41 at the upper edge of the inner pipe 312, so as to facilitate the control of the rotation of the inner pipe 312. The structure in which the spiral blade 3123 controls the rotation of the inner tube 312 improves the adjustment sensitivity of the wind power device 32 .

[0037] Working principle: When in use, connect the fire water pipe to the bottom of the transition connecting pipe 2211, or install a solenoid valve at the bottom of the ...

Abstract

The invention discloses an energy-saving fire-fighting unmanned aerial vehicle controlled by water energy, which comprises a multi-helix elevator, a three-axis platform and a water spray gun, and the water spray gun includes a water spray pipe and a wind device. In the present invention, the water spray gun includes a water spray pipe and a wind force device, wherein the wind impeller is arranged at the far end of the wind force device, the water spray pipe is rotated and connected to the inner pipe, the inner pipe is provided with a spiral blade near the outlet end, and the other end of the inner pipe is provided with a transmission shaft , the transmission shaft is connected to the wheel shaft of the wind impeller. When the water flows in the inner pipe and sprays water outward, the inner pipe rotates at a high speed under the action of the water flow, and then drives the wind impeller to rotate through the transmission shaft. The blades on the wind impeller interact with the air A reaction force is generated, the direction of which is opposite to that of the water spray reaction force of the inner pipe, and the magnitude is the same or approximately the same, thereby greatly improving the stability and energy-saving effect of unattended sprinkler fire extinguishing.

Description

technical field [0001] The invention relates to the technical field of fire-fighting drones, in particular to an energy-saving fire-fighting drone controlled by water energy. Background technique [0002] UAV fire extinguishing technology is gradually applied to high-rise building fires. The common structures of UAVs for fire extinguishing include multi-helical wing lifts, three-axis pan-tilts and fire-fighting launching devices. The fire-fighting launching devices pass through three-axis The bottom is connected, and the fire-fighting launching device is divided into a fire-extinguishing bomb launching device and a water spray gun. The water spray gun is more practical, effective and easy to operate than the fire-extinguishing bomb. [0003] However, the water spray gun will produce a water spray reaction force when spraying water, and the water spray reaction force varies according to the spray distance. Therefore, it is necessary to adjust the multi-rotor lift frame to a l...
