Water gun buffering mechanism for fire-fighting unmanned aerial vehicle

Abstract

The invention provides a water gun buffering mechanism for a fire-fighting unmanned aerial vehicle. The water gun buffering mechanism comprises a hanging bracket which is arranged below the unmanned aerial vehicle, the hanging bracket comprises a first guide rod, hanging rods are fixedly arranged at the two ends of the first guide rod respectively, the first guide rod is sleeved with a first guide sleeve, a buffering spring is arranged between the first guide sleeve and one of the hanging rods, and the buffering spring sleeves the first guide rod; the water gun buffering mechanism further comprises a water gun body, the first guide sleeve is fixedly connected with the water gun body, and the axis of the water gun body is parallel to the axis of the first guide sleeve; the water gun buffering mechanism further comprises a water pipe, one end of the water pipe is connected with the body of the unmanned aerial vehicle, the other end of the water pipe communicates with the end of the water gun, the water pipe comprises a U-shaped section, and an abutting wheel is arranged below the unmanned aerial vehicle, can move in the length direction of the first guide rod and abuts against the U-shaped section of the water pipe. Reacting force generated when water flow is jetted is absorbed through deformation of the buffering spring, so that posture changes of the unmanned aerial vehicle are reduced, meanwhile, the water pipe is supported through the abutting wheel, and the situation that the gravity center of the unmanned aerial vehicle is affected due to droop and shaking of the water pipe in the flying process of the unmanned aerial vehicle is prevented.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a water gun buffer mechanism for a fire-fighting unmanned aerial vehicle. Background technique [0002] With the development of drone technology, when danger occurs, in order to protect the lives of people and rescuers, drones have been used in many rescue work. In the field of fire protection, when the fire source is in a high-rise building , the fire brigade will use fire-fighting drones to extinguish fires. Fire-fighting drones usually carry water tanks and use their own water guns to spray water towards the fire point. Provide the initial velocity to ensure that the water is sprayed to the target. When the water leaves the water gun, it will cause a reaction force to the water gun, causing the drone's fuselage to tilt backward and shake. It is necessary for the drone to control the fire through its own algorithm or the ground. The machine adjusts...

[0002] With the development of drone technology, when danger occurs, in order to protect the lives of people and rescuers, drones have been used in many rescue work. In the field of fire protection, when the fire source is in a high-rise building , the fire brigade will use fire-fighting drones to extinguish fires. Fire-fighting drones usually carry water tanks and use their own water guns to spray water towards the fire point. Provide the initial velocity to ensure that the water is sprayed to the target. When the water leaves the water gun, it will cause a reaction force to the water gun, causing the drone's fuselage to tilt backward and shake. It is necessary for the drone to control the fire through its own algorithm or the ground. The machine adjusts its posture, but in this way, some of the water cannot be shot to the target, which causes a waste of water resources and prolongs the fire extinguishing time; moreover, the water gun and the water tank need to be connected by water pipes. Among them, the shaking of the water pipe is also easy to cause the center of gravity of the UAV to be unstable and reduce the flight performance of the UAV.
