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.

5. helix closing lid:

(1). coaxial installation one helix closing lid 14 on dynamical axis, this helix closing lid is shaped with the gap matched with helical blade shape and quantity, the madial wall of helix closing lid is shaped with power-assisted eaves 19, when helical blade rotates, its extrados 35 top is pressed on power-assisted eaves, and drive helix closing lid to rotate together with blade, work better to help helical blade.Its effect is, when blade start or at the end of, can because of the resistance of water, blade be contacted with closing lid or be separated.Meanwhile, Decompression accelerator operationally, can make between Decompression accelerator and bow, produces pressure release current, the pressure relief capability of Decompression accelerator is increased.

The radian that helix closing lid heads on, identical with the radian that helical blade and aircraft head on, supply the space left by helical blade, inlay close with helical blade normal incidence, time closed and aircraft surface quite.An axis hole is established at helix closing lid center, and be sleeved on helix closing lid axle, rotate freely, there are check screw restrictions on top.At the outer eaves of helix closing lid, there is the clamping ring of a ring shape, with the edge of reinforced closed lid.Closing lid is when surfacing, completely closed with hull, plays secret effect, is not easily found.

Principle of work of the present invention is:

When dynamical axis rotates forward, power post moves in the lifting groove of drive wheel inwall, makes the extrapolated interior endvertex walking to lifting groove of drive wheel, becomes the power resources of drive wheel, make power wheel and axle drive shaft synchronous rotary; Helical blade is released along push/pull slot by push-and-pull head, makes power arm crouch into push/pull slot, so that helical blade is fixed on power arm firmly, makes helical blade have firm power resources, makes helical blade rotary work; During drive wheel longitudinal travel, its outer rim top is pressed in the bottom surface of power-assisted eaves, and the extrados top of helical blade is pressed on power-assisted eaves, therefore can ensure helix closing lid and blade synchronous rotary.

When helical blade rotates, blade groove can make the water at its front and rear all penetrate rapidly along the hand of rotation of blade, forms mobile water curtain, makes the running resistance in aircraft front let out as deflection, thus make formation zone of negative pressure, blade groove rear, farthest reduce the resistance of navigation.

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

When using two structure embodiment illustrated in fig. 9, when dynamical axis rotates forward, separation type Decompression accelerator operationally, Decompression accelerator entirety is released and maintains a certain distance with naval vessel, water curtain is formed before naval ship water lower part and produces a zone of negative pressure, avoid as far as possible being attached to prematurely on hull, reach better acceleration effect.Also can according to circumstances determine the need of pull-out cavity; Submarine is then avoided pulling out cavity.
