Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, and in particular to a fire extinguishing helicopter bucket water spraying control device. Background Technology

[0002] Using helicopter buckets to extinguish forest fires involves spraying water onto forest combustibles, isolating them from the air and causing oxygen deficiency, or lowering the temperature of the combustibles below their ignition point, thus stopping the flames and extinguishing the forest fire. The liquid is discharged from the bottom of the bucket.

[0003] However, current sprinkler systems often experience blockages after use because the water collected from the bucket contains garbage or debris. Furthermore, most sprinklers use a free-fall method, which cannot accurately target the fire source, reducing firefighting efficiency. Therefore, it is necessary to design a firefighting helicopter bucket sprinkler control device. Utility Model Content

The lifting rope 24 connects the first connecting block 20 and the second connecting block 23, facilitating the lifting of the bucket body 1. During water intake, if the water contains garbage or other substances, the first filter plate 7 can filter out these substances, preventing contamination. If the spraying mechanism 4 becomes clogged, affecting fire extinguishing, the water can be filtered a second time through the second filter plate 9. Starting the motor 10 drives the spiral conveyor blades 11 to rotate, thus ensuring even water delivery. When watering is needed, the water pump 14 is started to draw water from the bucket body 1, which is then transported via the water pipe 15.
