Abstract

The invention discloses a marine propeller stirring energy conversion device and an application method thereof, and belongs to the technical field of marine equipment. The device comprises a main board body and defoaming fins; the main board body is provided with a limiting support rod end; a limiting sleeve is arranged at the end of the limiting supporting rod; the defoaming fins correspond to apropeller and are fixedly connected with a lead screw transmission structure; the lead screw transmission structure rotates relative to the limiting sleeve; the lead screw transmission structure is intransmission connection with a second transmission structure through the first transmission structure; and the second transmission structure is in transmission fit with an alternating-current generator. The device can receive spiral stirring energy generated by the propeller through the defoaming fins and rotate to eliminate bubbles; the lead screw transmission structure is synchronously driven to operate under the rotating action of the defoaming fins; the lead screw transmission structure drives the alternating-current generator to work via sequential transmission through the first transmission structure and the second transmission structure, so that spiral stirring energy generated by the propeller is effectively converted and utilized; and meanwhile, wake flow bubbles generated by operation of the propeller can be reduced, the cavitation effect is reduced, and the overall efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of marine equipment, in particular to a marine propeller turning energy conversion device and an application method thereof. Background technique

[0002] Propeller is one of the main propulsion methods of existing ships. At present, the propeller relies on two or more blades rotating in the water to drain backwards. During the process of draining backwards, they will be synchronously subjected to the reaction force from the water, thereby generating thrust to drive the ship forward. In the wake field generated by the propeller, while generating the average thrust, it will also generate short-distance screw driving energy. Most of these screw driving energy will be dissipated into the surrounding water as the ship advances. be effectively and fully utilized.

[0003] Moreover, when the ship moves forward, the wake bubbles generated by the propeller are very easy to form a cavitation effect, which will have...
