Abstract
The invention relates to a breaststroke underwater propulsion system which provides advancing power for an underwater apparatus in a frog simulating underwater motion way, drives a pull rod by a piston so as to drive an upper end framework and a lower end framework, enables the upper end framework, the lower end framework and the pull rod to interact by a lever principle so as to drive frog feet to move and provide advancing power for the underwater apparatus. The breaststroke underwater propulsion system has simpler structure, low underwater noise level, no wake flow, high concealment performance and lower manufacturing and using cost and is a potential underwater propulsion system.
Description
Technical field
The invention belongs to propulsion system field, naval vessel, relate to a kind of breast-stroke underwater propulsion system.
Background technology
The employed propulsion system in current naval vessel is to be advanced by screw propeller mostly, or obtains the power that advances by water spray, comparatively speaking, complex structure, to the technical requirements height, relative expense is also than higher, and, the noise of these propulsion modes is big, and wake flow is also big, and disguise is not high.
Summary of the invention
The present invention can provide a kind of relatively simple for structure for the equipment under water of cheapness, do not have wake flow, and noise level is relatively low, disguised higher, manufacturing cost and use cost is all very low, easy operating and maintenance, the imitation batrachia is the propulsion system of mode of motion under water.
Scheme of the present invention is, the upper middle of frog foot portions a bit is connected with the lower end of lower end skeleton, the lower end of frog foot portions top and bottom pull bar is connected, the upper end of bottom end pulling bar a bit is connected with the lower middle of upper end skeleton, skeleton upper middle, lower end a bit is connected with the lower end of upper end skeleton, the upper end of lower end skeleton is connected with the lower end of main tie, the upper end of upper end skeleton is connected with underbelly, and the upper end of main tie penetrates fuselage and is connected with pull bar on the fuselage inner carrier.
The invention has the beneficial effects as follows, can provide underwater propulsion system a kind of simple in structure, easy to use for the submerged organ material, it comes to provide the power that advances for equipment under water by the sub aqua sport mode of imitation frog.Its advantage is that noise is little, no wake flow, good concealment, easy operating.Because the parts that do not expose, so sealing better.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is when being in the bottom on the bent axle top, and frog foot is in the constitution diagram of recovery;
Fig. 2 is when bent axle top end and top, and frog foot is in the constitution diagram of downward draining.
Among the figure: 1. fuselage, 2. electrical motor 3. connects the transmission gear of electrical motor, 4. connects the transmission gear of bent axle, 5. bent axle, 6. connecting rod, 7. piston, 8. left side main tie, 9. right side main tie, 10. upper end, left side skeleton, 11. upper end, right side skeleton, lower end, 12. left side skeleton, 13. right side bottom end pulling bars, 14. lower end, right side skeleton, 15. left side bottom end pulling bars, 16. right side frog foots, 17. left side frog foot, 18. left sides connect piston pulling, and 19. right sides connect piston pulling.
The specific embodiment
Among the figure, with the left side is example, the lower end of the top and bottom pull bar 15 of some frog foot 17 that is connected with the lower end of lower end skeleton 12 of the upper middle of frog foot 17 is connected, the upper end of bottom end pulling bar 15 a bit is connected with upper end skeleton 10 lower middles, skeleton 12 upper middles in lower end a bit are connected with the lower end of upper end skeleton 10, the upper end of lower end skeleton 12 is connected with the lower end of main tie 8, the upper end of upper end skeleton 10 is connected with the bottom of fuselage 1, the upper end of main tie 8 in fuselage 1 be connected piston 7 on the lower end of pitch brace 18 be connected.So, when electrical motor 2 rotates, drive transmission gear 3, drive play gear 4 then, drive bent axle 5, and then drive piston 7 and move up and down, when piston 7 was in the bottom, frog foot 17 was to be in retracted state, when piston 7 moves to top, pitch brace 18 upwards spurs main tie 8, and at this moment the contact point of main tie 8 and fuselage 1 will become the fulcrum of lever, makes main tie 8 do lever motion, the bottom of main tie 8 will be received inwards, and push end skeleton 12 downwards, owing to skeleton 12 upper middles in lower end a bit link to each other with the lower end of lower end skeleton 10, like this, when main tie 8 time receiving inwards, upper end skeleton 10 is received simultaneously inwards, and lower end skeleton 12 will be that fulcrum is done lever motion a bit with what link to each other with upper end skeleton 10, and upper end skeleton 10 time receiving inwards, then promote coupled bottom end pulling bar 15 downwards, bottom end pulling bar 15 promotes frog foot 17 downwards, and frog foot 17 will a bit be done lever motion as fulcrum with what link to each other with lower end skeleton 12.Like this, when piston 7 was done the motion of one-period, total system will having moved as the back leg of frog.
