Abstract

The invention discloses a low-loss marine propeller, which comprises a first mounting base and a second mounting base. The middle parts of the first mounting base and the second mounting base are both provided with a paddle shaft mounting hole for mounting the paddle shaft. The first mounting base Both sides of the bottom surface of the seat are provided with a quarter-circular locking groove, and the upper surface of the first installation seat is equidistantly surrounded by first screw holes. The low-loss marine propeller adopts guide vanes to guide the flow at the edges of the first blade and the second blade, which can control the flow field to reduce energy loss, and due to the rotatable setting of the guide vanes, the The guide vanes can change directions along with the water flow to sort out the water flow, greatly reducing the influence of turbulent flow. The invention can not only eliminate turbulent flow and cavitation to reduce energy consumption and improve the service life of the propeller, but also facilitate In order to replace the damaged first paddle blade or the second paddle blade, the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of marine propellers, in particular to a low-loss marine propeller. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A marine propeller. As the most widely used propulsion equipment for surface or underwater vehicles, marine propellers have played an irreplaceable role since its inception, whether it is surface vehicles, such as ships, torpedoes, etc., or underwater vehicles, such as submarines, Submarines, etc., their propulsion is inseparable from the propeller. The propulsion efficiency of the propeller is related to the flow field around it. The turbulence of the flow field will reduce the propulsion efficiency of the propeller. Most of the current...
