Embodiment 1

[0052] Embodiment 1: A kind of fire extinguishing device of dragging power lead type multi-axis rotor UAV, such as figure 1 , 2 , 5, 6, 7, 8, 9, 10, 11 to 15, including ground equipment, multi-axis rotor type unmanned aerial vehicle 1 and connected with the ground equipment to provide a power supply wire 4 of high voltage, the unmanned aerial vehicle A high-pressure liquid spray device is connected, and the high-pressure spray head of the high-pressure liquid spray device is installed horizontally under the UAV, and the angle between the upper and lower spaces with the horizontal position of the UAV is realized by remote control between 0 and 22.5°. The high-pressure liquid spraying device is connected to the UAV through a high-pressure hose 2. One end of the high-pressure hose 2 is equipped with a high-pressure nozzle, and the end near the high-pressure nozzle is connected to the bottom of the UAV. The other end of the high-pressure hose 2 is connected to the UAV. The outlet...

Embodiment 2

[0066] Embodiment 2, the working principle and steps of this embodiment are the same as embodiment 1, as Figure 4 , the specific difference is: the high-pressure liquid spraying device is installed under the drone, including a portable water tank 12 and a portable high-pressure pump or high-pressure gas cylinder set 13 for pressurizing the flowing liquid, and the high-pressure pipeline is connected to the high-pressure spray head.

Embodiment 3

[0067] Embodiment 3, the working principle and steps of this embodiment are the same as those in Embodiment 1, the specific difference is that a three-way valve is installed on the high-pressure hose 2 of the drone near the nozzle to connect the hose branch An external socket is installed in series on the side of the power lead 4 close to the connection end of the drone, and the other end of the external branch and the hose branch are fixed at the corresponding position of another drone to achieve a relatively high altitude spray liquid.

[0068] Adopt the mode of relay fire extinguishing in this embodiment, refer to image 3 and Figure 5 , During the working process, the two-machine should maintain the proper horizontal safety distance, and the vertical distance should be less than the total length of the hose and wire between the two-machine minus the distance between the two-machine horizontal safety distance. In specific practice, multiple stages can also be stacked in ...

Abstract

The invention relates to a power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus and a fire extinguishing method and aims to solve the problem that an existing multi-shaft unmanned rotorcraft is low in effective load and short in aerial work time. The power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus provided by the invention comprises ground equipment, a multi-shaft unmanned rotorcraft and a power supply wire connected to the ground equipment for providing a high voltage; the unmanned rotorcraft is connected to a high pressure liquid spraying device, a high pressure nozzle of the high pressure liquid spraying device is horizontally mounted below the unmanned rotorcraft, and the upper and lower space included angel between the high pressure nozzle and the horizontal position of the unmanned rotorcraft is 0-22.5 degrees. The power supply wire-dragging type multi-shaft unmanned rotorcraft fire extinguishing apparatus has the beneficial effects that the effective load of the unmanned rotorcraft is improved, a reliable technical solution is provided for long-term aerial work of the unmanned rotorcraft, the self load can be effectively alleviated, and continuous feed is ensured. By way of supplying power and fire extinguishing agents in air in an alley-oop manner, the problem that the effective load of the single unmanned rotorcraft cannot meet the demand as the fire extinguishing height is raised can be effectively solved.

Description

technical field [0001] The invention relates to the field of high-rise building fire extinguishing technology and equipment, and relates to a fire extinguishing device and a fire extinguishing method for a multi-axis rotor unmanned aerial vehicle with a dragging power supply wire to effectively extinguish high-rise buildings outdoors by using a heavy-duty multi-axis rotor unmanned aerial vehicle. Background technique [0002] Since the reform and opening up, my country's high-rise building construction has developed rapidly, and the total number of high-rise buildings, especially the number of new super high-rise buildings each year, ranks first in the world for many years. The fire suppression of high-rise buildings, especially super high-rise buildings, is a worldwide problem. At present, the highest height of the fire truck in the world is the DG113 climbing platform fire truck developed by Zoomlion in May 2013, with a height of 113 meters. Due to the limitation of the s...
