Description
The present invention relates to a kind of vertical hydraulic injecting propulsion unit, the structure of this invention can reduce rotates the needed rotational force of housing.
Vertical hydraulic injecting propulsion unit is provided with a water inlet and a discharge port concordant with hull bottom.The device of outstanding hull bottom can not be conveniently used in the special vessel of shallow water operations, and for example a unsteady crane ship can not guarantee that enough propeller are immersed in the water because its draft is more shallow, can not adorn with common tunnel type propelling unit.Japanese unexamined publication application number is 6-278692,6-286693 7-52882, and files such as 8-58689 have disclosed the prior art of this vertical hydraulic injecting propulsion unit.This vertical hydraulic injecting propulsion unit allows housing main body to comprise a water outlet that can rotate in any direction in 360 ° of scopes, therefore, can produce propulsive force on selected arbitrarily direction, thereby improve the road-holding property of ship.
Fig. 6 is the section-drawing that above-mentioned Japanese unexamined publication application number is the disclosed vertical hydraulic injecting propulsion unit of file of 7-52882.Fig. 7 is the planar view of a bit looking from diffuser.
As shown in the figure,, flow to the upstream of propelling unit 51, converge mutually with the rotary water current that rotation by propelling unit 51 produces from the discharge current that the water inlet 53 of the core of the bottom 52a of housing 52 sucks.The diffuser 54 in propelling unit 51 downstreams changes the direction of rotary water current by blade 55, and passes through the direction of the effect change rotary water current of blade 55, radially flows out with the exit at blade.Because the existence of rotary water current, if drain water flows to the pressure chamber on the housing 52, rotating energy makes the loss due to friction between the surface of drain water stream and housing 52, and the result causes lot of energy loss.As for the effect of diffuser 54, because the cross section that it is designed to water-flowing path progressively increases, make the kinetic energy of current be transformed into the pressure energy gradually, thereby thrust is increased.The diffuser 54 that is provided with blade 55 is the requisite component parts of vertical hydraulic injecting propulsion unit.
According to above-mentioned traditional vertical hydraulic injecting propulsion unit, diffuser 54 and housing one or by integral installation on housing 52.Just because of this, the structure of this device is designed to housing 52 and diffuser 54 boths and drives and rotate by handling electrical motor 56.
As shown in Figure 7, the blade 55 of diffuser 54 is because the antagonistic force F of current produces rotational force (moment of rotation) Y along the direction of arrow.This rotational force be greatly to can making housing 52 rotate 360 ° in any direction, and has influence on the definite of the capacity of handling electrical motor significantly.That is to say, if housing 52 rotates by handling electrical motor 56, and the rotation direction of diffuser 54 is the direction of its suffered rotational force (torque) Y, this direction is shown in the arrow among Fig. 7, so housing 52 rotations, handle 56 of electrical motors and rotate (it need stop operating it by handling electrical motor conversely speaking) with less power.On the other hand, if diffuser 54 along the rotation of opposite direction, desired power is wanted to overcome following two power sums, the one, friction drag and by the moment that whole force of inertia produced of housing; The 2nd, by the rotating torque that current produce, it is much larger than preceding two power.The capacity of handling electrical motor is determined by power.Consumption of power is a very important factor, especially concerning by the barge of low generating capacity.Consider that from initial outlay and operation cost consumption of power is low more good more.Handle electrical motor and need be installed in the limited space, so the capacity of motor also requires to be reduced to smaller value, the size of motor is also as far as possible little.In the prior art of mentioning in front, housing 52 is equipped with a propeller shaft envelope 57, as shown in Figure 6.If the direction of rotation of the hand of rotation of housing 52 and propelling unit 51, the relative circumferential velocity that part is touched in the axle sealing-in equals its velocity of rotation and propelling unit velocity of rotation sum.Just because of this, the requirement that axle is sealed becomes very harsh, and also corresponding shortening the in service life of axle envelope.
File according to the open No.7-52882 of above-mentioned Japanese unexamined patent application has three discharge port in the bottom of housing 52, be and concentric circular-arc of water inlet near the end face of the middle discharge port of water inlet one side.The pilot blade that the application will describe is not installed in the inside of each discharge port.Do not consider drain water stream effective flowing in the horizontal direction in the clearly above-mentioned prior art.As a result, a part of current flow away under housing 52 bottoms significantly.Simultaneously, the moment of torsion that the roll-shell assembly needs comprises the turning effort that overcomes the kinetic energy of discharging current, and this kinetic energy is that the force of inertia by housing assembly etc. causes.If flow and direction overbalance from the side discharge port that places middle discharge port both sides flows out cause turning effort that moment of torsion is produced tremendous influence, the size of this power becomes the deciding factor that influences driving torque.For avoiding taking place such rotating torque, document 7-52882 points out to limit the size and the position of discharge port.In fact, balance must be determined, thereby produce undesirable rotating torque probably on specific direction.Because the increase of rotating torque, the capacity of handling electrical motor has also improved.In these cases, the bigger bigger in other words consumption of power of hydraulic pressure will be produced.
Therefore, the purpose of this invention is to provide a kind of vertical hydraulic injecting propulsion unit, the structure of this invention can reduce rotates the needed rotational force of housing.

As a result, realize from the current of discharge port ejection be not under but along continuous straight runs as far as possible, thereby can improve the efficient that thrust produces.
In the case, the draining pilot blade can be arranged to an angle, and the current of discharge port ejection are discharged with the direction opposite with water inlet.So just can avoid being inhaled into water inlet soon, thereby improve the efficient that produces thrust from the current of discharge port ejection.In addition, on water inlet the water inlet pilot blade can be set, this water inlet pilot blade is with an angle tilt, makes the direction of current of suction opposite with the direction of the current that spray from discharge port.Like this, can avoid the current of suction drain mouth ejection, thereby improve the efficient that thrust produces.
In addition, discharge port can be provided with in this wise, that is, a side discharge port that is symmetrical in the central row mouth of a river of the diameter line by the water inlet center and/or is arranged on these diameter line both sides symmetrically, and be arranged to the end face of water inlet one side of middle discharge port vertical with the direction of diameter line.Like this, the angle of inclination of side draining pilot blade just can change and regulate.So, can so that about the varying in size of propulsive force, produce a moment and compensate the rotating torque that the rotary water current that produced by angle of rake rotation causes.As a result, the manipulation power of electric motor of roll-shell needs just can reduce.
Have, if the angle of inclination of the pilot blade of middle discharge port can change and regulate, angle of rake load also just can have been regulated again.That is to say that if the area of discharge port strengthens, its load will reduce.If area reduces, load will increase.Method by accurate adjusting angle of inclination can be mated the adjustment primary mover easily with the rotating speed constant with respect to propelling unit.
