Embodiment Construction

[0009] Such as figure 1 , figure 2 As shown, the present invention has a three-cavity structure and a one-way valve system that automatically controls the water flow in and out according to the movement of the cavities. There is a closed cavity between the water inlet 2 and the water outlet 13 of the shuttle-shaped housing 1, which is installed in the shuttle-shaped The rubber plate I 3 and the rubber plate II 5 on the shell 1 divide the cavity into three cavities: cavity I 14, cavity II 15 and cavity III 16, and a water inlet valve is installed at 2 water inlets of cavity I14 I 7, water outlet valve I 10 is installed at water outlet 13; water inlet valve II 8 is installed at the water inlet of cavity II 15, and water outlet valve II 11 is installed at the water outlet; water inlet valve III9 is ​​installed at the water inlet of cavity 1II16, and water outlet Install the water outlet valve III12. Electromagnet I 4 is installed on the rubber plate I 3, and electromagnet II 6...

Abstract

The invention discloses an ultra-silence underwater propeller. Mechanical noise generated by an engine and mechanical transmission cannot be generated. The ultra-silence underwater propeller comprisesa spindle-shaped shell, wherein a closed cavity is formed between a water inlet and a water outlet of the shell; the cavity is divided into three cavity bodies by two rubber plates installed on the shell; one-way valves are installed at water inlets and water outlets of the cavity bodies; and electromagnets are installed on the rubber plates.

Description

technical field [0001] The invention relates to a military underwater ship propulsion system, in particular to an ultra-quiet underwater propeller. Background technique [0002] In the traditional propeller propeller system, the engine will generate insurmountable mechanical noise due to high-speed rotation and mechanical transmission system, which is not conducive to the lurking, detection and attack of military underwater ships. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an ultra-quiet underwater propeller, which does not generate mechanical noise generated by the engine and mechanical transmission. [0004] The basic idea of ​​the technical solution adopted by the present invention is: comprising a shuttle-shaped housing, a closed cavity is formed between the water inlet and the water outlet of the housing, and the two rubber plates installed on the housing sep...
