[0020] The equipment is composed of three sets of components: a water tank assembly, a water pump kit, and a spray pipe assembly.
[0021] The water tank body is welded by 304 stainless steel plate, and the assembly is installed under the belly of the BELL 407 helicopter through four clamping seats and four telescopic pull rods.
[0022] The water tank assembly can load 800KG of liquid. The inside contains five levels of high-strength buffer partitions with flow-stopping devices that can effectively block the impact force of the liquid in the tank body, keeping the aircraft stable, while the partitions have flow holes to avoid leaving residual liquid in the tank. The rear of the water tank assembly has two filling ports, one for the left firefighting equipment and the other for the right civilian equipment. The left quick-connect knob filling port can be directly connected to the fire hose, and the filling port has a pressure relief device. After the liquid passes through the pressure relief device, the water flow will be effectively slowed down to avoid damaging the equipment due to excessive pressure in the fire hose. The right filling port can be connected to ordinary water pipes or water carts and other equipment.
[0023] The water tank assembly is equipped with a throwing mechanism below, which can be used for emergency throwing and high-flow fire extinguishing. The water tank bottom has 10 throwing port valves. The mechanism consists of multiple connecting rods and a bottom ring, which can ensure simultaneous opening without delay. The mechanism contains two independent control devices. One set takes power from the aircraft and controls the electromagnetic valve through the water tank front-end control box to actuate the connecting rod, achieving valve opening. The other control system directly controls the throwing handle steel cable to make the throwing port valve mechanically linked, achieving throwing.
[0024] The jet power source of the entire system is a water pump installed on the right front landing gear skid, which is mainly controlled by the water pump start-stop control box in the cockpit. The water pressure jet is driven by a fuel-driven pump that can achieve three-stage pressure increase for the jet liquid. The water pump start-stop control box has a power supply that can control the start and stop of the water pump and adjust the water pump throttle in the cockpit. The water pump assembly is equipped with a throttle servo that can adjust the throttle at the water pump equipment end, achieving water quantity adjustment and equipment start and stop. The liquid in the water tank is sprayed through the 4.6-meter long carbon fiber jet hard pipe installed at the right landing gear pedal position, with a range of up to 30 meters. The pedal position has a lifting motor that can adjust the jet angle.
[0025] The jet hard pipe is a 3K carbon fiber pipe made of four 900mm pipes and one 830mm carbon fiber pipe bonded together using ergo 9966 glue. The bonding length of each two pipes is not less than 10cm. The carbon fiber strength is 1000 megapascals (MPA), and the modulus is about 100GPa.
[0026] The spray hard pipe is made of four 900mm pipes and one 830mm carbon fiber pipe, and is bonded by using ergo 9966 glue, and the bonding length of each two pipes is not less than 10cm, the carbon fiber strength is 1000MPa (MPA), and the modulus is about 100GPa. The spray hard pipe is sunk by about 10cm in the full water condition, compared with other spray pipes, the deformation degree is smaller, the compression resistance is strong, and the structural strength is good.
[0027] The lifting platform structure is a shearing type lifting structure, has stability, and controls the lifting motor in the cabin, the motor has a reset mechanism, avoids touching the ground, and can adjust the spray angle of the gun barrel in real time.
[0028] The throwing mechanism controls 10 throwing port valves at the bottom of the water tank. The mechanism includes two independent control devices, one of which takes power from the aircraft battery, actuates the throwing port valve through the water tank front end control box electric control electromagnetic valve, and the other is a standby control circuit which directly actuates through the "throwing handle-steel cable-throwing port valve" mechanical linkage.
[0029] The tank adjustment partition can effectively control the flow rate of the fluid in the tank, and slow down the impact on the aircraft.
[0030] The new type of filling interface can slow down the impact of water flow on the equipment during filling.
[0031] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to this, and various changes can be made within the knowledge range of the technical personnel in the technical field without departing from the purpose of the utility model.
