Abstract

The invention relates to a decompression accelerator comprising an outer box, a driving wheel, a paddle fixing wheel and spiral paddles. One push-and-pull groove is reserved on the inner side wall of each spiral paddle, a power arm is mounted in each push-and-pull groove in a guide-and-slide mode, and one arc baffle is arranged on the outer side wall of each spiral paddle. One arc paddle groove is formed between each arc baffle and the outer side wall of each spiral paddle. The decompression accelerator is mounted at the front end of an underwater vehicle. Through rotation of the spiral paddles, resisting force of frontal water flow generated during sailing is changed in direction, leaves a nose and spreads out around the nose; and a transverse-moving water curtain vertical to the heading is formed in front of the nose to prevent the nose from being hindered by the resisting force of the frontal water flow, so that frontal resisting force caused by route speed is reduced to the utmost, speed of the underwater vehicle is accelerated, voyage is extended, sailing duration is prolonged, energy is saved, and a higher maneuvering level of ships is achieved.

Principle of work of the present invention is:

When the dynamical axis forward, the power post moves in the lifting groove of drive wheel inwall, makes the extrapolated interior endvertex that walks to the lifting groove of drive wheel, becomes the power resources of drive wheel, makes power wheel and axle drive shaft synchronous rotary; The push-and-pull head is released helical blade along push/pull slot, and power arm is crouched into push/pull slot, so that helical blade is fixed on power arm firmly, makes helical blade that firm power resources be arranged, and makes the helical blade rotary work; During the drive wheel longitudinal travel, its outer rim is pushed up the bottom surface that is pressed in the power-assisted eaves, and the extrados of helical blade pushes up and is pressed on the power-assisted eaves, therefore can guarantee helix closing lid and blade synchronous rotary.

During the helical blade rotation, the blade groove can make the water at its place ahead and rear all penetrate rapidly along the hand of rotation of blade, forms mobile water curtain, and it is deflection that the running resistance in aircraft the place ahead is let out, thereby make blade groove rear formation zone of negative pressure, farthest reduce the resistance of navigation.

When axle drive shaft is done contrarotation, the power post is done contrarotation, rotate outer endvertex to the lifting groove along the lifting groove again, make drive wheel retract original position, the push-and-pull head is along with drive wheel is inwardly regained, the push-and-pull head hauls the push/pull slot of blade, and helical blade is regained, and closes in closing lid to stash.

When using two structure embodiment illustrated in fig. 9, when the dynamical axis forward, separation type pressure release accelerator is when work, the whole release with the naval vessel of pressure release accelerator maintained a certain distance, make water curtain form and produce a zone of negative pressure in the front of naval vessel lower apron, avoid as far as possible being attached to prematurely on hull, reach better acceleration effect.Also can according to circumstances determine whether to need to pull out cavity; Submarine avoids pulling out cavity.
