Fire extinguishing unmanned aerial vehicle capable of adjusting water spraying angle

Abstract

The utility model discloses a fire-extinguishing unmanned aerial vehicle capable of adjusting a water spraying angle, which comprises a rod body, belongs to the technical field of fire-extinguishing unmanned aerial vehicles, and aims to solve the technical problems that in the prior art, when an unmanned aerial vehicle fires a fire on a fire site, when the water spraying angle needs to be adjusted, firefighters need to control the whole unmanned aerial vehicle to adjust the direction, and the fire extinguishing effect is poor. The water injection nozzle cannot be automatically adjusted, the adjustment time is prolonged by adjusting the whole machine body, the fire fighting efficiency is reduced, and meanwhile the adjustment difficulty is also increased. The technical effects are as follows: the motor can be started to control the screw rod to rotate, so that the sliding block is controlled to slide along the surface of the camera probe, the transmission rod moves along with the sliding block and drives the sliding rod to slide in the sliding groove, and during sliding, the hose is driven by the adjusting plate to swing left and right around the conveying pipe, so that the conveying pipe is driven to rotate. Therefore, the spraying head swings left and right, and the water spraying angle is adjusted.

Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting drones, and in particular to a fire-fighting drone with an adjustable water spraying angle. Background Art

[0002] In recent years, the number of high-rise buildings in cities has gradually increased, but due to site limitations and lagging fire-fighting equipment in high-rise buildings, some high-rise fires lack effective means of extinguishing; some forest fires are difficult for large fire trucks to reach due to the fire scene conditions. At the same time, due to the complexity of mountain sites, especially cliff fires, personnel cannot reach the fire site to extinguish it directly, resulting in small fire spots not being cleared in time, causing the fire to spread further and worsen. When encountering such scenarios, the fire brigade generally uses fire-fighting drones to replace firefighters to extinguish the fire.

[0003] After searching, the applicant discovered a Chinese patent disclosure for "a fire-fighting drone," with publication number "CN214808005U." The patent includes a drone frame, an onboard power supply, an onboard water tank, a pump, a water supply pipe, a water gun, and a mounting assembly. The onboard power supply, water tank, and pump are all mounted on the drone frame. The onboard power supply is connected to the pump, the onboard water tank is connected to the water inlet of the pump, the water outlet of the pump is connected to the water gun via the water supply pipe, and the water gun is detachably connected to the drone frame via a mounting assembly. The fire-fighting drone provided by this utility model has the advantages of a wide fire-fighting range and convenient adjustment.

[0004] However, when the drone is performing firefighting work and needs to adjust the water spray angle, firefighters need to control the drone to adjust the direction as a whole, and the water nozzle cannot be automatically adjusted. Adjusting the entire fuselage increases the adjustment time, reduces the firefighting efficiency, and also increases the difficulty of adjustment. Utility Model Content

[0005] To this end, the present invention provides a fire-fighting drone with an adjustable water spray angle to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above purpose, this utility provides the following technical solutions:

[0012] Furthermore, the slide groove is designed to be linear, the slide rod and the transmission rod are arranged perpendicular to each other, and the transmission rod drives the hose to form a swinging structure.

[0013] Furthermore, a first groove is provided inside the connecting plate, a second groove is provided inside the connecting plate, the bottom of the frame is rotatably connected with forward and reverse screw rods, and the surfaces of the forward and reverse screw rods are threadedly connected with two groups of fixed blocks that are slidably connected to the bottom of the frame and embedded in the second groove.

[0014] Furthermore, the sizes of the first groove and the second groove are adapted to the fixing block, and the connecting plate forms a fixed structure inside the connecting plate through the fixing block.

[0015] The utility model has the following advantages: when it is necessary to adjust the water spraying angle of the sprinkler head, the motor control screw can be turned on to rotate, thereby controlling the slider to slide along the surface of the camera probe, and the transmission rod will also move accordingly, and drive the slide rod to slide inside the slide groove, and when sliding, it will drive the hose to swing left and right around the delivery pipe through the adjustment plate, so as to realize the left and right swing of the sprinkler head and adjust the water spraying angle. When it is necessary to disassemble and replace the fire extinguisher tank, the forward and reverse screw rods can be twisted to control the two sets of fixed blocks to slide along the bottom of the frame and move away from each other, and gradually slide out of the second groove. At this time, the connecting plate loses the clamping force of the fixed block and can be taken out from the inside of the connecting plate, thereby achieving the purpose of disassembling the fire extinguisher tank.
