The device comprises a hot air balloon body and a ground control assembly, wherein the ground control assembly comprises traction control mechanisms, power supply equipment, water supply equipment, monitoring equipment and a main controller; the hot air balloon body is connected with the traction control mechanisms by traction ropes; an aerial directional water spraying assembly is arranged on the hot air balloon body and is connected with and controlled by the ground control assembly. The device has the advantages of simple and compact structure, low cost, wide application range, good controllability, good fire extinguishment efficiency and the like.

Description

technical field [0001] The invention mainly relates to the field of water spraying equipment, in particular to a high-altitude fixed-point water spraying device mainly suitable for fire protection and other fields. Background technique [0002] At present, common high-altitude fire fighting and rescue methods mainly include the following: [0003] 1. Manual fire extinguishing and rescue: Although this rescue method has high accuracy, it requires rescuers to go deep into the fire scene, and the risk factor is high, causing a large number of casualties. Especially for fire scenes located at high or super high positions. [0004] 2. Rescue with high-altitude lifting device: There are two specific implementation methods for this method: (1) Use a ladder fire truck to extinguish the fire; due to the limitation of the length of the high-altitude crank arm, the height of fire extinguishing is greatly restricted; for example, the crank arm If it is too long, the slight shaking of ...

Problems solved by technology

(2) Use a climbing platform to extinguish the fire; the climbing platform is similar to the ladder fire truck, but the working platform is slightly different, and it cannot meet the needs of high-floor fire fighting

Moreover, the higher the fire protection height, the higher the requirements for the vehicle chassis, which puts forward greater requirements for the main body design of the fire truck, and it is difficult to realize. At present, no suitable solution has been proposed at home and abroad.

[0005] In short, if the pump truck using the high-altitude lifting device has the following series of disadvantages: insufficient height, complex system, limited lifting height of the lifting device (self-weight, strength and elasticity of the material itself), large and heavy system, and the lifting The device is too complicated and too heavy, so the ground vehicle is also very heavy, sacrificing the water load capacity, and the deployment time is longer, and the maneuverability is weak

[0006] 3. Ground sprinkler rescue: the general method mainly relies on water pressure to reach the fire extinguishing height due to the water spraying on the ground, the rescue height is greatly limited, and the water has been dispersed when it reaches high altitude, the water is not concentrated, and the strength is insufficient. Low fire extinguishing efficiency due to people being unclear about the fire point

The most advanced method at present is to use the latest super fire trucks to achieve higher water supply, but it takes a long time to erect fire standpipes, vertically lay fire hoses and rely on fixed fire facilities in the building to deliver water, generally for a floor of 100m It takes 2-3 hours to lay fire-fighting pipelines, which cannot meet the promptness and timeliness of fire-fighting

Moreover, the fire-fighting facilities in buildings in our country are not complete, and it is difficult to achieve this technical requirement.

[0007] 4. Helicopter rescue: Although helicopter fire extinguishing has good maneuverability and a wide range of applications, it is expensive and has limited load capacity. It cannot achieve continuous water supply. The water supply cycle is long and the use cost is high.

It mainly uses large-area indiscriminate spraying, the efficiency is not high, the impact on the surrounding area is greater, and the practicability for fire extinguishing inside the floors of high-rise buildings is not strong.
