Abstract

The invention relates to a marine propeller, which belongs to the technical field of propellers, and comprises a diesel engine drive, a vertical rod, an operating rod, a package, a propeller, a water seal, a main shaft positioned in the vertical rod, and a propeller shaft positioned in the package and connected with the propeller, wherein blades are arranged right in front of the propeller, and the blades are in the vertical surface of the axis of the propeller; a rudder blade drive connected with the vertical rod is arranged above the propeller and drives the rudder blade to swing left and right, a lower fixing plate connected with the package is arranged below the propeller, the lower fixing plate is connected with the lower end of the rudder blade, a protruding shaft is arranged at the position, perpendicularly below the main shaft, of the propeller shaft, and a forward rotation mechanism and a reverse rotation mechanism are arranged on the two sides of the protruding shaft respectively. The forward rotation mechanism or the reverse rotation mechanism is connected with the convex shaft; according to the propeller, coaxial forward rotation or reverse rotation can be achieved, turbulent flow generated by rotation in different directions can wash away dirt on propeller blades, dirt attachment is effectively reduced, and the maintenance period of the propeller is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of propellers, and in particular relates to a marine propeller. Background technique [0002] Marine propeller refers to the propulsion engine installed on the hull. Because of its high integration and simple installation and purchase, it is widely used in fish farming, commercial operations, and government law enforcement. Marine propellers are mainly divided into fuel marine propellers and electric marine propellers according to their energy sources. When the marine propeller is used, the marine propeller is usually suspended and installed on the transom, and the control device installed on the marine propeller is manually operated. The fan blades of the propellers of marine propellers will have fouling and solid waste attached, which is difficult to remove, and there is no protective measure outside the propellers, making the propellers vulnerable to impact damage. Therefore, a kind of marine propeller ...
