Driven gear key is connected on hollow shaft, and driving gear key is connected on machine shaft, and driven gear, driving gear engage; Pump into water inlet end and water side that water pipe and water pump outlet pipe lay respectively at water pump, water pump outlet pipe is connected with hollow shaft;
Ball shape nozzle one end is hollow cylinder, for being socketed with hollow shaft, and pumping into for water; Hollow cylinder is provided with screw thread mouth, fixing for installing; The Ball shape nozzle other end, is embedded with spheroid, ball centre axis has dug cylindrical hole, pumping for water; Sealing arrangement is provided with between spheroid and hollow cylinder.
Preferential, described water spray and screw propeller hybrid propulsion device, is characterized in that, the water spraying direction of the spheroid of described Ball shape nozzle can controlled change.
Described water spray and screw propeller hybrid propulsion device mode of operation comprise:
Mode of operation 1: motor rotary actuation driving gear, drive driven gear rotate, thus drive screw propeller on hollow shaft and axle to rotate; Meanwhile, water pump, from pumping into water pipe water suction, among in the hollow shaft that is connected with screw propeller, is discharged from the Ball shape nozzle of end, generation forward thrust.Thus maximum thrust can be provided, for quick sailing.
Mode of operation 2: only motor rotary actuation driving gear, drive driven gear rotate, thus drive screw propeller on hollow shaft and axle to rotate, water pump is as additional thrust mode, the water spraying direction of the Ball shape nozzle of end can be changed when changing course, produce lateral thrust, thus realize turning to.
Mode of operation 3: motor does not work, water pump service intermittent, by step mode of operation, can control aircraft preferably because the adverse effect brought in positional precision of its inertia factor is accurately to locate at local location.
Mode of operation 4: motor does not work, water pump continous way works, and because single waterjet propulsion noise is less, vibrates not serious, thus can avoid being monitored detection by other detectors in water.
The utility model is designed with end hollow shaft, and connects Ball shape nozzle, and when submarine navigation device needs to change course, by regulating the Way out of Ball shape nozzle, the antagonistic force of current can produce steering torque to aircraft.When aircraft needs to change the speed of a ship or plane, by regulating rotating speed or the close/open hydraulic efficiency jet propulsion system of motor, realizing the speed of a ship or plane and regulating.Obtain inspiration from the mode of motion of cuttlefish and carry out Bionic Design, by continous way work and the service intermittent of pump, realize continuous water spray and be interrupted water spray, ensureing that the local of aircraft is accurately located.
In general, the above technical scheme conceived by the utility model compared with prior art, can obtain following beneficial effect: owing to have employed water spray and the two propulsion system of screw propeller, overcome the inefficiency problem that tradition advances.Adopt continuous water spray and be interrupted water spray motor-driven, for flexible under different operational configuration, effectively can improve propulsion coefficient, improve the manoevreability of aircraft simultaneously.The design of waterjet propulsion has also made good road-holding property.Under the pattern of slipping into, use waterjet propulsion, vibration noise is little, good concealment.Negative pressure can be formed in stem, reduce the running resistance of aircraft.
