The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1 and Figure 2, thruster drag reduction denoising device comprises the thruster 3 that is located under hull 1 deck 2, thruster 3 comprises cylindrical channel 4, actuating device 5, the screw propeller 6 that runs through hull, and cylindrical channel 4 two ends are respectively equipped with fence gate 7, and cylindrical channel 4 two ends are provided with flame diversion trough 8.
Fence gate 7 is driven by the hydraulic efficiency gear 9 that bigger propulsive effort can be provided, driving fence gate 7 by rotating shaft 10 rotates, fence gate 7 preferably is set as the semi-round blade of two fan synchronized operations, two blades were middle involutory just when fence gate 7 was closed, chimeric with cylindrical channel 4 all around, and have sealing arrangement, have good leakproofness when guaranteeing fence gate 7 closures, reduce the generation of bubble.Rotating shaft 10 is located at respectively on every fan leaf, rotating shaft is supported and is located on the cylindrical channel 4, comprise shaft seat 11 and lower rotary shaft seat 12, rotating shaft 10 is supported by last shaft seat 11 and lower rotary shaft seat 12 and is axially rotated, preferable scheme is to be provided with poted assemblies 13 in last shaft seat 11, and anti-sealing penetrates into the cabin by rotating shaft place.Preferable scheme is rotating shaft 10 to be located at run through fence gate length of blade direction and the center of gravity by fence gate, and each fence gate is parallel to each other, and it is less that fence gate 7 opens and closes required space, do not influence the work of thruster 3.
