Abstract
The utility model provides a fast driving device for a submarine, which is characterized in that two mutually parallel front semi-circular water inlet cylinders are arranged at the two sides of the head of the submarine, and an inwards oblique semi-circular water inlet is arranged at the front end of each semi-circular water inlet cylinder; and an outwards oblique fan-shaped water outlet is arranged at the back end of the semi-circular water inlet cylinder and is connected with the side of the submarine to form an arc, and a propeller is arranged on a propeller shaft arranged on a shaft fixing carrier inside the semi-circular water inlet cylinder. The device can form the sea water low-pressure vortex flow in the front of the submarine and the sea water high-pressure vortex flow at the side of the submarine, so that the sea water resistance is lost, and the thrust is increased, thereby greatly improving the driving speed of the submarine.
Description
Affiliated technical field
The utility model belongs to the technical field of submarine moving velocity, has been specifically related to a kind of submarine mobile devices quickly.
Background technology
All navy submarines all adopt the rear-mounted propeller propulsion mode at present, and when submarine travelled, the seawater resistance of head, fuselage was very big, even strengthen power, the speed of submarine does not have big lifting yet.
Summary of the invention
When travelling in the existing navy submarine water, be subjected to the seawater drag effects, the deficiency that moving velocity is slow in order to overcome, the utility model provides a kind of submarine mobile devices quickly, this device can form the preposition seawater low pressure of submarine eddy current, makes seawater resistance forfeiture, makes that submarine is smooth and easy to move ahead; Simultaneously can form submarine sidepiece seawater high pressure eddy current, produce thrust forward, the route speed of submarine is obviously improved.
The solution of the utility model technical matters takes following scheme to realize: specifically by preposition semi-circular interior tiltedly flooding tube structure, fan-shaped outer tiltedly water outlet structure and screw propeller push structure interconnect composition.Its structure and annexation are to be equipped with two preposition semi-circular flooding tubes that are parallel to each other in submarine head both sides, semi-circular flooding tube front end is semi-circular interior tiltedly water inlet, the fan-shaped outer tiltedly water outlet of rear end becomes circular arc to link to each other with the other position of submarine side, is equipped with screw propeller on the screw shaft that the solid pedestal of semi-circular flooding tube in-to-in is provided with.
Principle of work of the present utility model is as follows: under the effect of power, make the screw propeller high speed revolution on the screw shaft, by oblique water inlet in semi-circular, submarine head fwd seawater is sucked semi-circular flooding tube, form meiobar, make submarine head seawater on every side flow to interior tiltedly water inlet, produce the low pressure eddy current, seawater resistance forfeiture in submarine front makes that submarine is smooth and easy to move ahead.Suck the seawater of semi-circular flooding tube simultaneously, tiltedly water outlet ejection outside fan-shaped after screw propeller rotation pressurization is on the one hand because antagonistic force moves ahead submarine; Make submarine sidepiece seawater on every side form the high pressure eddy current on the other hand, produce thrust forward, thereby submarine is moved forward fast.
The utlity model has following advantage and good effect: the one, the seawater resistance in head the place ahead forfeiture when submarine is advanced, power makes full use of.The 2nd, when submarine was advanced, the pressure of both sides strengthened behind the submarine, produced thrust forward, and under prime power unmodified situation, moving velocity increases.The 3rd, simple in structure, existing submarine all can be equipped use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the whole submarine scheme drawing under the utility model structure.
Fig. 2 is the utility model birds-eye view.
Fig. 3 is the utility model fundamental diagram.
1. semi-circular flooding tubes among the figure, 2. semi-circular in oblique water inlet, 3. screw shaft, 4. screw propeller, 5. fan-shaped outer tiltedly water outlet, 6. solid pedestal, 7. submarine head, 8. submarine sidepiece.
The specific embodiment
By the mobile devices quickly of the submarine shown in Fig. 1-3, be intrinsic two preposition semi-circular flooding tubes (1) that are parallel to each other in the both sides of submarine head (7), semi-circular flooding tube (1) front end is semi-circular interior tiltedly water inlet (2), the fan-shaped outer tiltedly water outlet (5) of rear end becomes circular arc to link to each other with submarine sidepiece (8), is equipped with screw propeller (4) on the screw shaft (3) on the solid pedestal (6) of semi-circular flooding tube (1) in-to-in.
During work, screw propeller (4) high speed revolution on screw shaft (3), through the suction of semi-circular flooding tube (1) front end, ejection rapidly backward moves ahead thereby promote submarine then.
Claims (1)
- A submarine quickly mobile devices be by oblique flooding tube structure in semi-circular, fan-shaped outer tiltedly water outlet structure and screw propeller push structure interconnect composition, it is characterized in that: be equipped with two preposition semi-circular flooding tubes (1) that are parallel to each other in the both sides of submarine head (7), the front end of semi-circular flooding tube (1) is semi-circular interior tiltedly water inlet (2), the rear end is fan-shaped outer tiltedly water outlet (5), fan-shaped outer tiltedly water outlet (5) becomes circular arc to link to each other with submarine sidepiece (8), the solid pedestal (6) of semi-circular flooding tube (1) in-to-in links to each other with screw shaft (3), is equipped with screw propeller (4) on the screw shaft (3).
