Description

Technical Field

[0001] The present invention relates to the technical field of UAV fire extinguishing, and particularly to a rapid water intake device for a special UAV for fire rescue. Background Art

[0002] As a new industrial technology, UAV fire fighting has been widely used in various fields. In China, many fire departments have successfully used UAVs for fire scene investigation and monitoring, throwing rescue supplies, etc. The effect is very obvious. During the rescue of the Tianjin explosion accident, various departments also used UAVs to conduct high-altitude investigations on the accident site, providing some reference basis for rescue decisions. With accurate, intuitive, and comprehensive fire scene analysis data, the application of fire extinguishing UAVs can directly carry water by the UAV and directly conduct accurate fire extinguishing on the fire points.

[0003] The existing fire fighting UAVs have the following problems during water intake and the subsequent fire extinguishing process: When taking water, a large amount of air remains in the water intake tank. Relying on its own gravity to take water, the process of filling water by itself is very slow and cannot achieve rapid water filling. And when extinguishing a fire, the water outlet structure at the bottom is single and cannot adjust the fire extinguishing range according to the size of the fire point. The existing technology is not easy to solve such problems. Therefore, there is an urgent need for a rapid water intake device for a special UAV for fire rescue to solve the above problems. Summary of the Invention

In the initial state, the steering gear controls the two spray water tanks 4 at the bottom to close. When taking water, the steering gear controls the two spray water tanks 4 to open to both sides. The driving motor 14 at the top drives the two driven bevel gears 12 to rotate through the driving bevel gear 13. The two traction rope rollers 10 rotate to release the traction ropes 7.

The floating ball abutment block 28 pushes up the floating ball 18. The water inside the water intake tank 8 can flow into the drainage swing blocks 30 at the bottom. The two driving pumps 19 can increase the drainage power. When draining water to extinguish a fire, the lifting lead screw 36 controls the lifting of the lifting ring 32 to realize the angle adjustment of the nine drainage swing blocks 30, and the angle of the water discharged from the top during fire extinguishing can be adjusted, and the fire extinguishing area can be adjusted according to the size of the fire.
