Problems solved by technology

[0002] Most of the propulsion systems currently used by ships are propelled by propellers or powered by water jets. Relatively speaking, the structure is complex, the technical requirements are high, and the relative cost is relatively high. Moreover, the propulsion methods of these Loud noise, big wake, low concealment

Embodiment Construction

[0010] In the figure, taking the left side as an example, the upper part of the middle of the frog foot 17 is connected to the lower end of the lower end frame 12. The upper end of the frog foot 17 is connected to the lower end of the lower end rod 15 and the upper end of the lower end rod 15 is offset from the middle of the upper end frame 10. The upper end of the lower end frame 12 is connected to the lower end of the upper end frame 10, the upper end of the lower end frame 12 is connected to the lower end of the main tie rod 8, and the upper end of the upper end frame 10 is connected to the lower part of the fuselage 1. The upper end of the tie rod 8 is connected to the lower end of the piston tie rod 18 connected to the piston 7 in the body 1. In this way, when the motor 2 rotates, it drives the transmission gear 3, then drives the shift gear 4, drives the crankshaft 5, and then drives the piston 7 to move up and down. When the piston 7 is at the bottom, the frog foot 17 is in...

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 [0001] The invention belongs to the field of ship propulsion systems, and relates to a frog type underwater propulsion system. Background technique [0002] The propulsion systems currently used by ships are mostly driven by propellers or water jets to obtain forward power. Relatively speaking, they have complex structures, high technical requirements, and relatively high costs. Moreover, these propulsion methods are The noise is large, the wake is also large, and the concealment is not high. Summary of the invention [0003] The invention can provide cheap underwater equipment with a simple structure, no wake, relatively low noise level, high concealment, low manufacturing and use costs, easy operation and maintenance, and imitating frogs. Propulsion system for underwater movement. [0004] The scheme adopted in the present invention is that the upper middle point of the frog foot part is connected to the lower end of the lower end frame, the upper end of the fr...
