Description

Technical Field

[0001] The present invention belongs to the technical field of fire protection, and in particular, relates to a super high-rise building fire extinguishing system and method based on an unmanned aerial vehicle. Background Art

[0002] Buildings are generally equipped with indoor fire protection systems in accordance with fire protection design requirements. A normally working fire protection system can generally extinguish fires within the design specifications. For fires that exceed the design fire extinguishing capacity, external force is required to extinguish the fire. Currently, fire trucks are mainly used for fire fighting. However, for fires in super-high-rise buildings, current fire trucks are powerless and can only rely on the building's indoor fire protection system.

[0003] With the continuous development and maturity of drone technology and its own advantages, drones are widely used, low cost, high efficiency-cost ratio, strong survivability and no risk of casualties, good maneuverability, and easy to use. Drones are used in more and more fields, such as firefighting, monitoring, security, and reconnaissance. Therefore, it is a very effective firefighting measure to use firefighting drones to arrange fire cables in super high-rise buildings. One end of the firefighting cable is fixed on one side of the super high-rise building, and the other end is stretched across the roof of the super high-rise building and fixed on the other side of the super high-rise building. After that, the rope climbing machine is used to climb up along the firefighting cable with a fire hose to reach the fire floor to extinguish the fire at close range. At present, there are mainly two ways to arrange firefighting cables: one is that firefighters climb to the top of the building under the premise of ensuring safety and throw down the two ends of the firefighting cable; the other is to use a rope throwing gun to throw the firefighting cable to the top of the building or cross the top of the building and fix the two ends of the firefighting cable on the ground. However, the above two methods are time-consuming and laborious. Using firefighting drones to carry firefighting cables to the top of the building for the arrangement of firefighting cables has become a better way to arrange firefighting cables.

[0004] A search of CN110525656A disclosed a super high-rise building fire extinguishing system and method based on drones, which is used to solve the problem of fire fighting in super high-rise buildings. An electric ducted drone is arranged in the fire truck to provide power and water respectively. After the electric ducted drone is controlled by the ground control station to take off and reach the predetermined fire extinguishing height, the high-pressure fire water pump assembly works to transport water to the water faucet through the high-pressure fire hose to carry out fire extinguishing operations.

[0005] However, the inventors have discovered through exploration that the technical solution still has at least the following defects: in the above-mentioned method of extinguishing fires in super-high-rise buildings by using fire-fighting drones, the water spray assembly is directly installed on the fire-fighting drone. When extinguishing a fire, the fire-fighting drone needs to be close to the fire point. If the flames at the fire scene are large, it is easy to cause damage to the fire-fighting drone. If the fire-fighting drone is not close to the fire source, it cannot extinguish the fire source in time.

[0006] In view of this, the present invention is proposed. Summary of the invention

The fire-fighting drone carries a winding assembly and a pulley guide assembly to fly to the roof of a high-rise building. After the fire-fighting cable passes over the roof of the high-rise building, the ground control unit controls the release assembly to release the fire-fighting cable, so that the fire-fighting cable falls to the ground. When the fire-fighting cable falls to the ground, the fire-fighting cable is fixed to complete the wiring of the fire-fighting cable. At this time, the winding assembly and the pulley guide assembly provided can guide the fire-fighting cable to prevent the fire-fighting cable from interfering with the propeller of the fire-fighting drone during its descent. After the wiring of the fire-fighting cable is completed, the water spray assembly is fixed on the load crawling device, and the load crawling device moves along the taut The fire-fighting cable crawls upward, and the water spraying assembly follows the load crawling device to crawl on the fire-fighting cable. The high-pressure fire hose follows the crawling of the water spraying assembly to be released.
