Advantage and disadvantage of the present invention, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the embodiment of the present invention one;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the structural representation of the embodiment of the present invention two;
Fig. 4 is the right elevation of Fig. 3.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 to 4, the present invention includes 3 pieces of wave suppression plates, 1,3 pipe links 2 and wave suppression plate control apparatus 3, wave suppression plate 1 middle inside is vertical with pipe link 2 outer end to be connected, and 3 pipe link 2 the inners are vertical with axle sleeve 4 radial direction to be respectively fixedly connected with.Wave suppression plate 1 is the fabricate block of one end arc other end flat board, arc angle α=30 of wave suppression plate 1 one end ° ~ 60 °.Can effectively control multi-angle oblique wave, increase wave suppression plate 1 and the area of contact of wave, increase the unrestrained angle of pressure, improve the unrestrained effect of pressure.
Wave suppression plate control apparatus 3 is arranged in stern transom plate 10, comprise stepping motor 31, horizontal drive shaft 32 and two bearing seats 33, horizontal drive shaft 32 the inner is fixedly connected with stepper motor output shaft 311 by coupler 34, horizontal drive shaft 32 outer end is fixedly connected with axle sleeve 4 after passing stern transom plate 10, sealed by seal ring 35 between horizontal drive shaft 32 and stern transom plate 10, can prevent current from leaking in cabin from stern transom plate 10.Stepping motor 31 is supported on inner support seat 36 by motor base 312, inner support seat 36 left end vertical welding is fixed on stern transom plate 10 medial surface, outer support seat 37 right-hand member vertical welding is fixed on stern transom plate 10 lateral surface, and horizontal drive shaft 32 two ends are supported on outer support seat 37 and inner support seat 36 respectively by bearing seat 33.Outer support seat 37 is equipped with the case 38 covering bearing seat 33, protection bearing seat 33 avoids it to lose efficacy because of corrosion.
Stepping motor 31 carries out Angle ambiguity by electric machine controller regulating impulse signal, the continuity that stepping motor 31 of the present invention is different from conventional motor rotates, but when navigating by water according to high-speed boat after its stern spray size carry out interval type and turn an angle, adjust the pressure wave position of different wave suppression plate 1.
The length of head rod 21, second pipe link 22 and the 3rd pipe link 23 is than L1:L2:L3=1:1.4 ~ 1.6:1.8 ~ 2.2.Accelerate at high-speed boat, speed stabilizing and difference navigation stage of sliding, stepping motor 31 rotates respective angles, the pressure wave degree of depth that the pipe link 2 of 3 different lengths can be corresponding different, thus meets wave pressed at various speeds by high-speed boat demand to wave suppression plate 1.
The horizontal projection of wave suppression plate 1 is rectangle, the circular arc radius R of wave suppression plate end face one end and ratio R:A=0.4 ~ 0.8 of the long limit A of rectangle; The long limit A length of rectangle is captain's 1/10 ~ 1/8, and the minor face B length of rectangle is captain's 1/12 ~ 1/10; Arc angle α=30 of wave suppression plate one end ° ~ 60 °, can effectively control multi-angle oblique wave, increase wave suppression plate and the area of contact of wave, improve and press unrestrained effect.
Embodiment one
As shown in Figure 1, the head rod 21 of the present embodiment is fixedly connected with into yi word pattern with the second pipe link 22 by axle sleeve 4, and the head rod 21 of the 3rd pipe link 23 and yi word pattern and the second pipe link 22 intersect vertically and be fixedly connected with.Stepping motor 31 carries out Angle ambiguity by electric machine controller regulating impulse signal.When quick of high-speed boat startup is sliding, drive wave suppression plate 1 half-twist to find correct position to suppress the spray by electric machine controller transmitter pulse signal by stepping motor 31, what hull generation was added upwards lifts stern lift, reduction running resistance.When high-speed boat high speed operation, slide and turn time, for ensureing high-speed boat stable sea and avoid afterbody to occur whipping phenomenon, wave suppression plate also will rotate respective angles, and head rod 21 is all adjusted to vertical down position.Stepping motor 31 is hybrid two-phase stepper motor, and basic step angle is 1.8 °/step.
Embodiment two
As shown in Figure 3, head rod 21, second pipe link 22 and the 3rd pipe link 23 of the present embodiment are fixedly connected into uniform trident by axle sleeve 4, and 120 ° of angles each other between adjacent pipe link, all the other structures are identical with embodiment one.When fast rising sliding after high-speed boat starts, driving wave suppression plate 1 rotational angle to suppress the spray by electric machine controller transmitter pulse signal Driving Stepping Motor 31, hull being produced and additional upwards lifts stern lift, reducing resistance.When high-speed boat high speed operation or when sliding, now high-speed boat is in plateau substantially, regulates wave suppression plate 1 to rotate counterclockwise 60 ° or 180 ° from position shown in Fig. 1, avoids wave suppression plate 1 at vertical down position, do not affect the normal/cruise of high-speed boat.When high-speed boat needs to turn, in order to avoid whipping phenomenon appears in afterbody, wave suppression plate gets back to initial position shown in Fig. 1, thus avoids wave suppression plate 1 obstruction to turn to.The present embodiment compensate for the limitation that embodiment one wave suppression plate rotates 90 ° of uncontrollable oblique side sprays at every turn, can meet the requirement of multi-faceted pressure wave.Stepping motor 31 is hybrid three-phase stepper motor, and basic step angle is 1.2 °/step.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
