Description
Technical field
The present invention relates to a kind of boat propulsion engine, it has the device for creating lifting power that is used to produce lift, so that at hull (boats and ships) stern is risen.
Background technology
In the boats and ships that move on the water by the propulsive force of boat propulsion engine, stern is at boats and ships and descends when static and be submerged under water.When the hull setting in motion, stern further descends and the fore rise.Thus, both sides on the bow form conical surface wave.Hull is orientated to above wave and travels, and promptly its orientation places and overcomes bow wave.Therefore, hull tilts when the boats and ships setting in motion.Because water is very big when the boats and ships setting in motion to the resistance (resistance of motion) of hull, very difficult realization reaches enough ship's speed (hull speed).
In order to increase ship's speed, must be by the orientation that stern risen to a certain degree make hull near level.Yet if do not take special measure, hull need reach near horizontal alignment for a long time.Boat propulsion engine leaves some room for improvement and allows hull to quicken fast and reposefully.Given this, in tradition is implemented, open among communique No.57-60995 (JP-A-57-60995) and the 59-130799 (JP-A-59-130799) the Japanese Patent spy and to disclose device for creating lifting power, described device for creating lifting power makes stern and boat propulsion engine rise when the boats and ships setting in motion.

Yet the wing plate of disclosed boat propulsion engine is set to length basically in the front end from anti-cavitation extends to the scope of rear end in U.S. Patent No. 4738644.Therefore, because the wing plate is difficult to produce enough lift, when the boat propulsion engine setting in motion, fast and to rise the effect of the stern that floods reposefully very little.The orientation movement of hull is become near level, thereby be difficult to realize quickening more stably.And when hull was advanced by boat propulsion engine, strengthening part and bracing frame produced the resistance to water.
In the disclosed boat propulsion engine, anti-cavitation is set in place around the shell of screw propeller top in U.S. Patent No. 5645009, and horizontal adapter plate is attached on the end face of anti-cavitation, and in the rear end of adapter plate upper support deflecting plate is arranged.Deflecting plate is supported for can be from level attitude to lower swing.Deflecting plate is by swinging the downward-sloping backward lift that produces.
Yet, the deflecting plate of disclosed boat propulsion engine conversion between level attitude and obliquity in the U.S. Patent No. 5646009, and by remaining on obliquity from boat propulsion engine or from the bar that stern extends.Therefore, be used to produce device (the comprising deflecting plate) complex structure of lift, and need to switch the operation of this device.In addition, no matter whether complex structure, and it is enough that deflecting plate self can not be considered as with respect to the rigidity of lift.
Consider these, need a kind of device for creating lifting power, it can produce lift so that promote stern fast and reposefully.Also need to improve the rigidity of device for creating lifting power, so that bear sizable lift.

The front edge of plate body 21 has along the arc-shaped depression portion 21r of the rear surface 4a of extensional shell 4, as shown in Figures 2 and 3.Therefore, recess 21r centers on rear surface 4a and is integrally formed on the 4a of rear surface.
The front end 21a of plate body 21 is positioned at the longitudinal middle part of extensional shell 4.The rear end 21d of plate body 21 is positioned at the back upper place of the rear end 11a of anti-cavitation 11, promptly in the back upper place of screw propeller 8.
The whole shape of plate body 21 from above can be regarded as essentially rectangular when seeing.
Four following qualifications of line P1-P4 shown in Fig. 2.The first line P1 is the horizon of the end face 11b of extend through anti-cavitation 11.The second line P2 is the bottom surface 21g (downwards alignment surfaces 21g) of extend through plate body 21, promptly along the horizon of the bottom surface 21g of forebody 21b and pars intermedia 21c.The second line P2 is parallel to the first line P1.Three-way P3 is the perpendicular line of the rear end 11a of extend through anti-cavitation 11.Nature, the three-way P3 and the first line P1 and the second line P2 meet at right angles.The 4th line P4 is the bottom surface 21h bevelled straight line of the 21e of rear-inclined portion in the plate body 21.
Border between bottom surface 21g (alignment surfaces 21g downwards) and the bottom surface 21h (inclined surface 21h) is represented by curve 21i.Curve 21i is positioned at the back upper place of the rear end 11a of anti-cavitation 11.In other words, curve 21i is arranged in the rear of the three-way P3 of Fig. 2.Therefore, the bottom surface 21h of the 21e of rear-inclined portion is positioned at the back upper place of the rear end 11a of anti-cavitation 11, promptly in the back upper place of screw propeller 8.
In Fig. 2, the tiltangle 1 of the 21e of rear-inclined portion, promptly (line P4 is with respect to the angle θ 1 of line P2 with respect to bottom surface 21g bevelled angle θ 1 for inclined surface 21h; Acute angle), preferably be set in the scope of 1≤45 ° of 0 °≤θ.In addition, particularly preferably be, tiltangle 1 is set at about 30 °.Tiltangle 1 also can be described as the angle of attack.
More particularly, the second distance of separation a2 is substantially equal to (a1 ≈ a2) or greater than (the first distance of separation a1 of a1＜a2).Yet (under the situation of a1＞a2), preferably the second distance of separation a2 is greater than 90% of the first distance of separation a1 less than the first distance of separation a1 at the second distance of separation a2.The second distance of separation a2 also can be the shortest distance from the rear end 11a of anti-cavitation 11 to the bottom surface 21h of plate body 21.
As shown in Figure 4, when when boat propulsion engine 1 is seen at the rear, the width W 1 of plate body 21, the i.e. width W 1 of device for creating lifting power 20, be preferably set to the maximum width W2 (W1 ≈ W2) that approximates boat propulsion engine 1 greatly, or be slightly less than maximum width W2 (W1＜W2).Further preferably the width W 1 of plate body 21 is set at much larger than the external diameter of screw propeller 8.Its reason is as follows.
For example, in some cases, according to size and other features of hull Si shown in Figure 1, a plurality of boat propulsion engines 1 are installed on the stern St side by side.By being set, a plurality of boat propulsion engines 1 can increase the power that advances hull Si.All boat propulsion engines 1 are swung to the left and right when hull Si turns to.
If the width W 1 of device for creating lifting power 20 is greater than the maximum width W2 of boat propulsion engine 1, then when turning to, hull has such possibility, that is: a plurality of device for creating lifting power 20 interfere each other, or device for creating lifting power 20 interferes with adjacent boat propulsion engine 1.Preferably the width W 1 to plate body 21 limits to avoid such interference.
And when as shown in Figure 4 when boat propulsion engine 1 is seen at the rear, a plurality of support components 24 are disposed in the scope of width W 3 of extensional shell 4.More preferably, these a plurality of support components 24 are arranged to not to stretch out profile above extensional shell 4 to the side.Therefore, when hull Si travels forward, can reduce to form resistance, during motion of ship, can reduce and splash, and can realize that pulsation-free promotes action by the wave that support component 24 causes.
Above-mentioned device for creating lifting power 20 is summarized as follows.
As shown in Figures 2 and 3, device for creating lifting power 20 has and is positioned at extensional shell 4 (main body 4) rear at least and with respect to the surface (bottom surface 21g and bottom surface 21h) of extensional shell 4 lateral widenings.In addition, device for creating lifting power 20 comprises the 21b of first, 21c and second portion 21e, the 21b of first, 21c constitute the first substantially parallel bottom surface 21g, and second portion 21e constitutes the curve 21i extension and the sweptback second bottom surface 21h continuously downwards backward from the first bottom surface 21g.
The operation of device for creating lifting power 20 then, is described with reference to Fig. 1 and Fig. 2.
When the propulsive force of hull Si by boat propulsion engine 1 travels forward, in the upper and lower surface of the downward sweptback rear-inclined 21e of portion, produce pressure reduction.Thus, in plate body 21 (device for creating lifting power 20), produce hoisting force or so-called lift.
When boats and ships stopped, because the buoyancy of hull Si and the balance between the center of gravity, hull Si kept certain rise orientation on the bow.When boats and ships stopped, fore kept rising, and the fore-and-aft tilt angle of hull Si is for example about 5 °.Under this state, the bottom surface 21g of plate body 21 with respect to the horizontal plane becomes low-angle, perhaps is called as recess angle (recessed angle) (for example about 5 °).
Then, when advancing beginning, act on a power so that boat propulsion engine 1 side of hull is sunk.Being in fore-and-aft tilt angle when static is under the about 5 ° situation, stern St sinks from this position owing to quicken, and the fore-and-aft tilt angle reaches maximum 15 °, so 21h angle with respect to the horizontal plane in bottom surface increases 15 ° from 30 ° of previous angles, making this angle is 45 °.Because this angle is 45 °, vertical force component (lift) is no more than horizontal component of force.Therefore, can improve acceleration capability in this case, because upwards resistance is no more than resistance backward.
This lift makes hoisting force act on from bottom to top on the plate body 21.Because the 21e of rear-inclined portion recedes downwards, this hoisting force acts on the continuous curve as repeated boad by rake and acts on all peripheral part.
In order to handle this repeated boad, a plurality of support components 24 (support component 24) are arranged to extend up to forward from the end face 21f of the pars intermedia 21c of plate body 21 the rear surface 4a of extensional shell 4.Support component 24 has realized being used for the effect of supporter of the repeated boad of supporting role on plate body 21,, is used to strengthen the effect of the doubler of plate body 21 that is.
Particularly, support component 24 is made of three quite thick upright plates.All upright plates are separated from each other to the left and right and are parallel with erectility.The bottom 24a of support component 24 is set on the end face 21f integratedly, the boundary vicinity between pars intermedia 21c and the 21e of rear-inclined portion.
The front end 24b of support component 24 is wholely set on the top of the rear surface 4a of the periphery wall of extensional shell 4 (main body 4 of boat propulsion engine 1).By this way, support component 24 makes the end face 21f of plate body 21 be connected integratedly with the rear surface 4a of extensional shell 4.Particularly, the front end 24b of support component 24 is set on perisporium vertical latter half of of extensional shell 4.
Because the front end 24b of support component 24 is set on the rear surface 4a of extensional shell 4, the distance between the end of support component 24 can shorten, thereby can reduce the size of support component 24.In addition, can reduce to form resistance from propelling resistance that is installed in the support component 24 on the device for creating lifting power 20 and wave.Also can when hull Si moves, reduce and splash, and can realize that pulsation-free promotes action.Term " wave formation resistance " is meant the formed resistance of wave that is travelled forward and produced by hull Si.
As shown in Figure 4, when when vertically seeing extensional shell 4, support component 24 is arranged in the maximum width W3 of extensional shell 4.Particularly, when along the perisporium of the main body of boat propulsion engine 1 vertically especially when the place ahead is seen, support component 24 is arranged on (in the width of the submerged condition of boat propulsion engine 1) in the maximum width scope.Therefore, the wave in the time of can reducing boat propulsion engine 1 and advance boats and ships forms resistance, also can reduce to have the propelling resistance of the boat propulsion engine 1 of device for creating lifting power 20.
As mentioned above, when boat propulsion engine 1 operation, hull Si setting in motion, at this moment the lower part that comprises device for creating lifting power 20 of boat propulsion engine 1 is submerged (as shown in Figure 1), and stern St reduces under the center of gravity of the weight of boat propulsion engine 1 and hull Si and the equilibrium activity between the buoyancy.
When the boats and ships setting in motion, comprise that the stern St of boat propulsion engine 1 rises by the lifting action of device for creating lifting power 20.The propulsive force of boat propulsion engine 1 allows to produce fast and reposefully lift.This lift is by receding downwards and being positioned at screw propeller 8 tops and the effect of the inclined surface 21h that extends back is upwards risen plate body 21.
Load on the device for creating lifting power 20 is supported by support component 24.
As mentioned above, the pass of the first distance of separation a1 and the second distance of separation a2 is " a1 ≈ a2 ", " a1＜a2 " or " (0.9 * a1)＜a2 ".The water that flows backward along the end face 11b of anti-cavitation 11 is along the tilted deflecting of the bottom surface 21h of the 21e of rear-inclined portion, and is discharged to the rear portion reposefully and can not hindered near the 21d of rear end.
Therefore, when the boats and ships setting in motion, boat propulsion engine 1 and stern St can rise fast and reposefully, and the orientation of the hull Si in the motion can become near level in the short time at the utmost point.Therefore, being attached with the hull Si of boat propulsion engine 1 can be fast and become reposefully at a high speed.
