The operation principle of the utility model：
The utility model is installed below helicopter ventral, and carrying fire-fighting well-bucket 1 by helicopter reaches water source overhead, will hang
Bucket 1 into the water, starts control power supply, and discharging valve 10 is opened, while pulsating pump 4 is started to work, and water is evacuated in staving, is completed
Well-bucket 1 is fetched water.
Control device 9 is used for that well-bucket 1 is controlled to fetch water with discharging water, and well-bucket 1 is water storage unit, is furnished with self-priming in its staving bottom
Water-bound is made of discharging valve 10, pulsating pump 4, filter screen 5 and buffing pad 7, can be realized to fetch water in shallow water area and be put out a fire.It is logical
After electricity, valve body 2 is moved upwards along spool 13, and discharging valve 10 is opened, and pulsating pump 4 is started to work, by water from bottom in staving
Portion conveys, and filter screen 5 can prevent the impurity in water from damaging pulsating pump 4, and bearing 6 is used for supporting pulsating pump 4 and filter screen 5, pass through
Bolt in circumferential direction is connected firmly with staving bottom, and buffing pad 7 can play cushioning effect, avoids landing on slave after 1 completion task of well-bucket
When hit 4 grade spare parts of pulsating pump.
In the present embodiment, valve body 2 moves up and down along spool 13, when being moved downwardly to 6 snap of bearing, discharges water
Valve 10 is closed, and carrying well-bucket 1 by helicopter after installation is complete for fire-fighting well-bucket 1 reaches water source overhead, by well-bucket 1 into the water,
Startup power supply and control device 9, discharging valve 10 are opened, and pulsating pump 4 is started to work, and are stopped water intaking after well-bucket 1 fills water, are discharged water
Valve 10 is closed, and is then carried well-bucket 1 and is flown to fire overhead, and starting discharging valve 10 by control device 9 carries out the fire extinguishing that discharges water.
The utility model can repeat to open and close to discharge water, when motor drives the rope 12 that discharges water to tighten and overcomes spring force with moving valve 2
When leaving bearing 6 with the pressure of water, discharging valve 10 is opened at this time, and water is from the opening outflow on bearing 6, when motor drives the rope that discharges water
During 12 release, under the action of the pressure of spring force and water, bottom is adjacent on bearing 6 valve body 2 completely, and discharging valve 10 closes at this time
It closes；In the utility model, motor release discharges water rope 12 when making the natural compressing support 6 of valve body 2, and hardly energy consumption, tension is put
When water rope 12 makes the rising of valve body 2, valve body 2 only need to be drawn high to very short distance, you can it discharges water, the top and bottom of valve body 2
Opening, not only ensure that valve body 2 while sealed with spool 13 can freedom and flexibility moved along guide rod 3, also reduce drawing
The obstruction area of water when dynamic, therefore motor need to be smaller with electric current；In the utility model, after valve body 2 is separated with bearing 6, water is straight
The surrounding connect from valve body 2 pours in the opening discharge of bearing 6, and waterdrainage amount is big；The utility model is simple in structure, at low cost, installation side
Just.
Above is only the preferred embodiment of the utility model, cannot limit the power of the utility model with this certainly
Sharp scope, therefore the equivalence changes made according to present utility model application the scope of the claims, still belong to the scope of protection of the utility model.
