Description
Technical field
The utility model belongs to aviation fire-fighting fire extinguishing equipment technology field, and in particular to a kind of to use suction type Absorb Water side
The fire-fighting well-bucket of formula.
Background technique
When traditional helicopter is fetched water using fire-fighting well-bucket, generally fetched water using immersion water intaking and pump sump mode.
Using immersion water intaking sunk naturally using the gravity of staving itself, lifted after in staving whole immersion water, it is complete
At fire-fighting well-bucket water intaking process, this water-supply method water intaking needs to fetch water the requirement of the region depth of water not less than 2m；Pump sump mode
Water intaking is filled the water in bucket using staving bottom high speed axial-flow pump, is lifted after all filling water in bucket, and fire-fighting well-bucket is completed
Water intaking process, pump water absorption type water-supply method require water intaking depth requirements to be not less than 0.5m.
Dewatering outlet is closed up and is opened using multiple hawser ropes when existing fire-fighting well-bucket discharges water, and this mode can only
It is disposable to open, it turns off after water discharges, can not be again turned on after closing, flow discharges and the rhythm that discharges water are unable to control, no
Conducive to the reasonable utilization at precious water source, it is unfavorable for putting out a fire in time, affects fire-fighting efficiency.
In conclusion current fire-fighting well-bucket is limited by water intaking depth when fetching water, optional water intaking range is reduced；When discharging water
Dewatering outlet can only disposably open and close, and cannot rationally utilize water source, and therefore, there is water intaking ranges for fire-fighting well-bucket at present
It is small, the disadvantages such as water source service efficiency is low.
