Abstract

The present invention relates to a water spraying type thruster. Mainly, an inner pipe is arranged in the outer pipe. A fluid cavity with a narrow conical clamping channel is arranged between the inner pipe and the outer pipe. The narrow conical clamping channel of the fluid cavity and a main axis form an alpha spraying angle. A spraying pipe and a water inlet pipe which are communicated with the fluid cavity are connected to the outer pipe. The outer pipe is connected with a water pump which uses a motor as a power source through the water inlet pipe. The water pump works under the action of the motor. The water of the water pump is expedited and sprayed from the narrow conical clamping channel of the fluid cavity; meanwhile, the water coming from a center pipe of the inner pipe is sucked. Two sections of water are together sprayed from the spraying pipe at a high speed to generate great thrust force, and the thrust force can be used as the power of a ship, a naval vessel or a submarine to push the ship, the naval vessel or the submarine to fast advance. The present invention not only generates low noise, but also can effectively enhance the speed of the ship, the naval vessel or the submarine, and the present invention can prevent the ship, the naval vessel or the submarine from being disturbed by foreign matters in water. The present invention is favorable for the navigation of the ship, the naval vessel or the submarine.

Description

Water spraying propelling device

Technical field

The present invention relates to a kind of marine propulsion, particularly water spraying propelling device, it is applicable to steamer, naval vessels and submarine in the defense Industry.

Background technology

At present, the ship that navigates by water in water, warship mostly adopt propeller to promote to advance as power.Owing to be as power with propeller, the noise that makes ship, warship produce is big, is difficult to improve their route speed again, and because of propeller be to place under water, be easy to be tied, make troubles for the navigation of ship, warship by the foreign material of under water pasture and water or shabby fishnet and so on.

Summary of the invention

The object of the present invention is to provide a kind of water spraying propelling device, it can overcome the deficiency of prior art, not only can avoid being tied by foreign material under water, but also noise is little, can improve ship, warship route speed effectively.

Its solution is: interior pipe is housed in the outer tube, between inner and outer pipe, form fluid cavity, one end of fluid cavity is narrow taper passageway, and become the α angle of spray between narrow taper passageway and the spindle axis, fluid can spray along the α angle from the narrow taper passageway of cavity, is connected with the jet pipe and the coolant inlet pipe that are connected with fluid cavity on outer tube.And the angle of spray α=35-45 between narrow taper passageway and the spindle axis °.When the accelerating jetting of the narrow taper passageway of the fluid cavity of the water of coming between inner and outer pipe by coolant inlet pipe, aspirate simultaneously the water of coming in again from interior tube hub pipe, two strands of water at high speed together sprays from jet pipe, can produce huge thrust.

Interior pipe is equipped with in the present invention in the outer tube, between inner and outer pipe, form the fluid cavity that has narrow taper passageway, become the α angle of spray between the narrow taper passageway of this fluid cavity and the spindle axis, on outer tube, be connected with the jet pipe and the coolant inlet pipe that are connected with fluid cavity.This thruster is connected with the water pump that with the motor is propulsion source by coolant inlet pipe, water pump is worked under the effect of motor, during the narrow taper passageway accelerating jetting of the fluid cavity of the water of water pump between inner and outer pipe, the water that the tube hub pipe is come in aspirating again simultaneously, two strands of water at high speed together sprays from jet pipe, produce huge thrust, the size of this thrust depend on the size of the power of motor that adopts and pump capacity.This thruster is used for steamer, naval vessels or submarine, the thrust that it produced can be used as the power of steamer, naval vessels or submarine, steamer, naval vessels or submarine can produce forward acceleration under the promotion of this power, their route speed will be more and more faster along with putting off of time so, and the resistance that produces until their speed equates with thrust.As long as regulate the flow of water pump according to the navigation needs of reality, i.e. rotating speed of motor, the route speed of adjusting control steamer, naval vessels or submarine at random just can improve the moving velocity of steamer, naval vessels or submarine effectively.Simultaneously,,, can not be subjected to the interference of being tied again, more help the navigation of steamer, naval vessels or submarine by foreign material in the water so the noise that produces is little because the thrust that produces with water spraying propelling device is the onward impulse of steamer, naval vessels or submarine.

The specific embodiment

Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing

Among Fig. 1, outer tube 5 is by straight tube and the big cone pipe 7 of one end bonded assembly, and other end bonded assembly shrinks Taper Pipe 2 and constitutes.Pipe 3 in being equipped with in the outer tube 5, interior pipe 3 is connected with the outer tube 11 of fine taper pipe 9 by an end, be set with base pipe 12 in the outer tube 11, one end of base pipe 12 is connected with fine taper pipe 9 on the outer tube 11, and captives joint with the internal chamber wall of outer tube 11 other ends by three uniform front end panels 4 and to constitute.And the other end of base pipe 12 is connected with the contraction Taper Pipe 2 of outer tube 5 one ends, and outer tube 11 is captiveed joint with the internal chamber wall of outer tube 5 one ends by three uniform rear bearing sheets 6 again.Forming fluid cavity 10 between inner and outer pipe 3,5, is narrow taper passageway in an end of fluid cavity 10, and the water in this narrow taper passageway of flowing through sprays with acceleration/accel.On the big cone pipe 7 of outer tube 5, be connected with the jet pipe 8 that is connected with fluid cavity 10, be connected with the coolant inlet pipe 1 that is connected with fluid cavity 10 on the side.And coolant inlet pipe 1 is the 45 bend pipe, and its line of centers and spindle axis are 45 ° of angles.

Among Fig. 2, water spraying propelling device 13 places water, and by coupled and place the water pump 14 of water, is connected with motor 15 on being installed in steamer or naval vessels.If the power of the motor 15 that is adopted is 1100KW, the flow of water pump 14 is 400m ³/ h.Water pump 14 is worked under the effect of motor 15, the narrow taper passageway accelerating jetting of the fluid cavity 10 of the water of water pump between inner and outer pipe, meanwhile aspirate the water of coming in from base pipe 12, two strands of water at high speed together sprays from jet pipe 8, produce huge thrust, obtain the thrust of 1422kg according to water speed and flow rate calculation.Steamer or naval vessels produce forward acceleration under the effect of this thrust, it is advanced fast.

Among Fig. 3, be installed in water spraying propelling device 13 as the wheel or the cabin of naval vessels in, and by being connected with water spraying propelling device 13 and also being installed in water pump 14 in steamer or the naval vessels cabin, be connected with motor 15 in being installed in steamer or naval vessels cabin.Described water pump 14 preferably adopts the axial flow pump of big flow.Water pump 14 is worked under the effect of motor 15, can produce foregoing huge thrust, thereby promotion steamer or naval vessels double ring ahead are travelled.
