Specific embodiment
Further details of elaboration is done to technical solution of the present invention in the following with reference to the drawings and specific embodiments.
Embodiment: as depicted in figs. 1 and 2, a kind of installation method of helicopter fire plant is first in helicopter (figure
In be not shown) bottom part down be arranged one have water tank 1 hanger 2, then on hanger 2 be arranged connecting rod 3 so that the one of connecting rod 3
End is connect across water tank 1 with hanger 2, and the other end of connecting rod 3 is connected to and is gone straight up on motor spindle；Then in the side of hanger 2
Increase a bracket 1, water injector 5 is installed on bracket 1.The present embodiment by helicopter underhung hanger,
Remaining equipment is connected with hanger, and water injector is made to be integrated into an entirety, will by using the external applied load structure type of outer hanger
All devices and attachment are integrated in one, and increase helicopter external applied load work capacity and make full use of helicopter external applied load in this way
Ability, helicopter itself do not do any repacking, greatly reduce installation difficulty, and the safety eliminated in helicopter fire-fighting operation is hidden
Suffer from, meets the demand of high building fire extinguishing.
Herein, air suspension damping is also provided in the other end of the connecting rod (not show in figure
Out), the other end of the connecting rod is connect by air suspension damping with motor spindle is gone straight up to.It can eliminate so in-flight
The high frequency momentum that water tank vibration generates, ensure that flight safety.The air suspension damping includes cylinder, by by cylinder
Cylinder body and connecting rod other end connect, the piston rod of cylinder is connect with motor spindle is gone straight up to, so that other the one of connecting rod
End is connect by air suspension damping with motor spindle is gone straight up to.
One bracket 26 is set again in the other side of hanger 2, fire extinguishing bullet launching device 7 is installed on bracket 26.
Effect when can further increase fire-fighting fire extinguishing by adding fire extinguishing bullet launching device.
Extinguishing fluid fast interface 8 and the water inlet pipe 10 with self priming pump 9 are additionally provided on the water tank 1；
When fire occurs, fire helicopter can reach rapidly scene of fire, be in light condition, due to fire in water tank at this time
Field condition is complicated, and fire-fighting vehicle can not necessarily reach rapidly scene of fire, when fire-fighting vehicle has arrived at or close to fire
When phenomenon, the extinguishing fluid in fire-fighting vehicle can be transported to water tank by 8 extinguishing fluid fast interface 8 of extinguishing fluid fast interface at this time
Water spray fire fighting is carried out by water injector 5 in 1；It, at this time can be by with certainly when fire-fighting vehicle reaches scene of fire not yet
The water inlet pipe 10 of sucking pump 9 is having water place (such as pond, rivers etc.) that water is pumped into water tank 1, is sprayed water by water injector 5
Fire fighting.Therefore, the present embodiment can according to the actual situation, to select different modes to load extinguishing fluid into water tank rapidly, quickly
Efficiently enter scene of fire and carries out fire-fighting fire extinguishing operation, it is practical.
As shown in figure 3, the water injector 5 includes the high-pressure pump 111 being arranged on bracket 1 and is connected to high-pressure pump 11
Hydraulic giant 12, also set up battery (not shown) on helicopter, high-pressure pump 11 (is not gone out by conducting wire with controller in figure
It is electrically connected out), the controller is placed in helicopter cabin, and battery provides startup power supply for high-pressure pump；When progress fire-fighting
When, controller is manipulated in helicopter cabin by operator, to open or close high-pressure pump, utilizes hydraulic giant shower
Carry out fire-fighting fire extinguishing.Some is installed at the electricity that the power supply that the water injector on helicopter uses carries for helicopter in the prior art
Source, but the power supply that helicopter carries also needs to power for other electrical equipments on helicopter, this mode can be to helicopter flight
When safety threaten, in addition the present embodiment is additionally arranged a battery, without making to guarantee the flight safety of helicopter
With the power supply of helicopter itself, safety when helicopter flight is ensured that in this way.In addition, the controller in the present embodiment is logical
It crosses conducting wire to be placed in helicopter cabin, such operator can directly manipulate in helicopter cabin, without arriving
It is operated outside helicopter, ensure that the personal safety of operator.It is additionally provided on bracket 1 and provides energy for high-pressure pump
The fuel tank 13 in source.
As depicted in figs. 1 and 2, a kind of helicopter fire plant is also disclosed in the present embodiment comprising setting is in helicopter (figure
In be not shown) hanger 2 of bottom part down, hanger 2 going straight up to motor spindle by the setting of connecting rod 3, water tank 1 is provided on hanger 2；
One end of connecting rod 3 passes through water tank 2 and connect with hanger 2, and the other end of connecting rod 3 and the bottom of helicopter connect；The one of hanger 2
It is provided with bracket 1 on side, water injector 5 is provided on bracket 1.
As shown in Figure 3 and Figure 4, the water injector, the high-pressure pump including helicopter (not shown) bottom is arranged in
11 and the hydraulic giant 2 that is connected to high-pressure pump 11, the hydraulic giant 2 include gun barrel 14 and nozzle 15, gun barrel 14 and nozzle 15 are welded into one
One end of body structure, gun barrel 14 is connected to high-pressure pump 11, and nozzle 15 is arranged in the other end of gun barrel 14；The gun barrel 14 is
Multi-stage reducing diversion pipe, i.e., it is axial along gun barrel 14, from one end of gun barrel 14 toward 15 direction of nozzle, the inner tube of multi-stage reducing diversion pipe
Diameter gradually becomes smaller.The effect of high hydraulic pressure, Far Range is not achieved in the water column ejected in existing helicopter fire-fighting, and is going straight up to
When machine fire-fighting operation, the environmental factors such as rotor wind caused by the ontology of helicopter and aerial sidespin wind complexity can be to ejecting
Water column have an adverse effect so that the state of scattering can be presented in the water column ejected, the requirement of water column concentration is not achieved, thus
Can not high building fire extinguishing demand, and the present embodiment using stage variable pressure design, to eject by multi-stage reducing diversion pipe
Water column increase by 3 times of effects, and make water column concentrate 1 times of effect so that the water column ejected in the present embodiment can reach
To 30 meters of concentration water column range, water column is set to realize high pressure, the shooting of long flow, to meet the demand of high building fire extinguishing.
The gun barrel 14 includes level-one diversion pipe 141, second level diversion pipe 142 and three-level diversion pipe 143, level-one diversion pipe
141 interior diameter is greater than the interior diameter of second level diversion pipe 142, and the interior diameter of second level diversion pipe 142 is greater than three-level diversion pipe 143
Interior diameter.Water column is realized so that water column passes through three-level transformation before ejecting using three-level variable diameter guide flow pipe in the present embodiment
Range increases, the effect that water column is concentrated.
As shown in Figures 4 to 6, one end of the level-one diversion pipe 141 is connected to (not shown), level-one with high-pressure hydraulic pump
The other end of diversion pipe 141 is connected to by circular cone shape conduit 1 with one end of second level diversion pipe 142, second level diversion pipe
142 other end is connected to by circular cone shape conduit 2 17 with one end of three-level diversion pipe 143, and the setting of nozzle 15 is led in three-level
In the other end of flow tube 143；The stub end of circular cone shape conduit 1 and circular cone shape conduit 2 17 is respectively positioned on close to high pressure
