Description
Technical field
The present invention relates to screw propeller field, more particularly to a kind of axial-flow pump formula screw propeller.
Background technology
Traditional auger type propeller, general existing screw propeller, must be produced whenever rotating a part from
Mental and physical efforts.A part of water centrifugation is lost, makes the power of water change of the part to back pressure radially, produces noise, reduce thrust.
If it is intended to increase thrust, there is following measure：
1st, rotating speed is increased, but it is big to consume energy, noise is big, and centrifugation loss can be big；
2nd, increase propeller and push away water area, but be intended to area increased diameter to increase, enlarged diameter resistance arm will add
Greatly, resistance arm resistance just corresponding increase, power consumption increase.
In addition, in military field, noise caused by propeller is easily found, and is sunk by enemy.
Therefore, designing a kind of axial-flow pump formula screw propeller, solves problem above.
The content of the invention
The present invention is overcomes the above insufficient, there is provided a kind of axial-flow pump formula screw propeller, including main shaft, the main shaft from
Front to back is sequentially provided with motor, to wheel, clutch shaft bearing, propeller and second bearing；The clutch shaft bearing and propeller it
Between the main shaft be provided with sealing function the first seal closure, with cover the motor, to wheel and clutch shaft bearing；
The propeller is multiple along being axially arranged with for the main shaft, and the outside of multiple propellers is covered with the propeller water conservancy diversion of tubular
Cover, the edge of the propeller kuppe is provided with silencing means；Set on the main shaft between the second bearing and propeller
There is the second seal closure, to cover the second bearing.
Preferably, the motor is permanent magnet motor.
Further, the silencing means is Noise reduction tile.
The beneficial effects of the invention are as follows：
A kind of axial-flow pump formula screw propeller of the present invention, easy to use, several times of less energy consumption；Thrust is big；Noise
It is small several times；Mobility strong.
Brief description of the drawings
Fig. 1 is a kind of structural representation of axial-flow pump formula screw propeller of the present invention；
Wherein：The seal closures of 1- first；2- clutch shaft bearings；3- is to wheel；4- propellers；5- second bearings；The seal closures of 6- second；
7- propeller kuppes；8- silencing means；9- main shafts；10- motors.
Embodiment
It is described in detail referring to the drawings below with reference to embodiments of the invention.
A kind of axial-flow pump formula screw propeller, including main shaft 9, the main shaft 9 are sequentially provided with motor from front to back
10th, to wheel 3, clutch shaft bearing 2, propeller 4 and second bearing 5；On the main shaft 9 between the clutch shaft bearing 2 and propeller 4
Provided with the first seal closure 1 with sealing function, to cover the motor 10, to wheel 3 and clutch shaft bearing 2；The spiral
Slurry 4 is multiple along being axially arranged with for the main shaft 9, and the outside of multiple propellers 4 is covered with the propeller kuppe 7 of tubular, institute
The edge for stating propeller kuppe 7 is provided with silencing means 8；Set on the main shaft 9 between the second bearing 5 and propeller 4
There is the second seal closure 6, to cover the second bearing 5.
Preferably, the motor 10 is permanent magnet motor.
Further, the silencing means 8 is Noise reduction tile.
Principle：
Axial-flow pump formula propeller is to increase several propellers 4 on coaxial, and propeller kuppe 7 is set up in periphery, is filled
Driven in the both sides of ship, and with motor 10, under water line at 1m-1.5m, increase with displacement tonnage and deepen.
1st, the increase of the water surface is pushed away, thrust adds several times；
2nd, too many, corresponding less energy intensive is not increased because resistance arm does not increase corresponding resistance；
3rd, because there is the application of propeller kuppe 7, the current of centrifugation are made to become axial thrust, less centrifugation is lost, accordingly
Be exactly to increase thrust；
4th, because propeller kuppe 7 is tubular, other positions are all closed in addition to front and rear mouth, are disappeared if increased on barrel
Sound equipment, then noise is reduced, and water conservancy diversion acoustical panel is set up in front and rear mouth, its noise then reduces several times, enemy can not be used sonar
Detect, use on submarine more preferably；
5th, the axial-flow pump formula propeller is located at hull both sides, and is driven with motor 10, makes hull flexibility increase,
Hull can the rotation of 360 ° of original place.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
