Problems solved by technology

The ship's main engine, main shaft, and transmission device are all huge, and the manufacturing and processing costs are high, the cost of use is also high, and the maintenance cost is also high. The main engine occupies a large space in the ship's cabin; the main axis to the blade tip The greater the distance, the greater the power required; when the blade is rotating, the water will form a vortex in the front and back of the blade, which will consume the driving force; since the propeller is only at the stern, the wave-making resistance at the bow is very large. The maneuverability of the ship is poor, and the stability of the ship decreases as the speed of the ship increases

Abstract

The invention relates to a propeller without a power shaft electromagnetic roller. The propeller comprises a propelling unit, a shell, an electric rudder and a mounting device. The propelling unit isinstalled in the shell and provided with a waterproof power plug. The shell is provided with an internal waterproof power socket and an external power plug. The shell is provided with the electric rudder and the mounting device. The mounting device is provided with an external power socket. The propeller can be widely used for all types of ships and can be assembled required positions of the two sides of sterns and prows and ship sides, the ship stability and flexibility can be improved after the propeller is used, the navigational speed is increased, and the manufacturing cost and use cost are reduced. In addition, the propeller has the advantages of being easy to maintain, assemble and disassemble, capable of saving energy and the like.

Description

technical field [0001] The invention relates to the field of ships, in particular to a non-powered shaft electromagnetic drum propeller propeller. Background technique [0002] The current paddle propeller propeller is driven by the power of the main engine in the ship, and the main shaft extends out of the hull to drive the propeller to rotate and propel the ship to sail. The ship's main engine, main shaft, and transmission device are all huge, and the manufacturing and processing costs are high, the cost of use is also high, and the maintenance cost is also high. The main engine occupies a large space in the ship's cabin; the main axis to the blade tip The greater the distance, the greater the power required; when the blade is rotating, the water will form a vortex in the front and back of the blade, which will consume the driving force; since the propeller is only at the stern, the wave-making resistance at the bow is very large. The maneuverability of the ship is poor, ...
