U-shaped circulating convection wing plate propelling device

Abstract

The invention relates to a U-shaped circulating convection wing plate propelling device which comprises a circulating pipeline with an integrated hollow structure, and openings in the two ends of thecirculating pipeline are oppositely formed at intervals. A wing plate is mounted in a gap between openings in the two ends of the circulating pipeline, an adjusting seat is mounted at the end of the wing plate, and the swing axis direction of the wing plate along with the adjusting seat is perpendicular to the connecting line of the openings in the two ends of the circulating pipeline; wherein oneor more groups of axial flow pumps are arranged in the circulating pipeline along the axial direction, openings at two ends of the circulating pipeline are respectively an inlet end and an outlet end, under the action of the axial flow pumps, fluid flows out from the outlet end after entering from the inlet end of the circulating pipeline and then enters from the inlet end through the wing platesto form circulation, and the circulating fluid generates a thrust force to the wing plates. Therefore, when most of fluid circularly flows in the pipeline to generate thrust, the wake characteristicof an existing propeller is effectively restrained, and the low-noise and quiet operation of the propelling device is greatly assisted.

Description

technical field [0001] The invention relates to the technical field of underwater navigation propellers, in particular to a U-shaped circulation convection vane propulsion device. Background technique [0002] In the prior art, a ship or an underwater vehicle mainly converts mechanical energy into kinetic energy for the ship to advance through a rotating part—the propeller. force. [0003] The propeller propeller has the advantage of high propulsion efficiency, but it has inherent deficiencies in the control of vibration, noise, and cavitation. In water, it is easy to cause vibration, noise and cavitation problems; in addition, during the rotation of the propeller, a part of the energy will inevitably be brought into the wake. The strength of the trailing target is not conducive to its target concealment. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a U-shaped circulation conv...

[0003] The propeller propeller has the advantage of high propulsion efficiency, but it has inherent deficiencies in the control of vibration, noise, and cavitation. In water, it is easy to cause vibration, noise and cavitation problems; in addition, during the rotation of the propeller, a part of the energy will inevitably be brought into the wake, such as cavitation on the surface of the blade, which is easy to transmit the air bubbles to the far rear, increasing the The strength of the trailing target is not conducive to its target concealment
