Electric water-spraying propeller

Abstract

The invention discloses an electric water-spraying propeller, and belongs to the technical field of the propeller. The propeller comprises a motor and a propulsion mechanism connected with the motor;a motor shell and a rotating shaft penetrating through the motor shell are arranged on the motor; a propeller shell connected with the motor shell, a propeller shaft penetrating through the propellershell, a propeller sprayer fixedly connected with the propeller shell and a screw propeller sleeved on the propeller shaft are arranged on the propulsion mechanism; one end, sleeved with the screw propeller, of the propeller shaft is located in the propeller sprayer, and the other end is connected with the rotating shaft through an internal spline coupling. By integrally arranging the motor and the propeller and independently arranging the control in the motor, the redundant connecting cable is reduced, and the power transmission is optimized, the structure is compact, the propeller can be completely arranged underwater without independently designing a water-cooling loop; the radiating effect is good, and an aim of improving the working efficiency is improved.

Description

technical field [0001] The invention relates to a propeller, in particular to an electric water jet propeller, and belongs to the technical field of propellers. Background technique [0002] A water jet propeller refers to a propeller that uses the reaction force generated by the jet water to drive the ship forward by immersing the jet part of the propulsion mechanism in water. It is composed of water pumps, pipes, suction ports and spouts, etc., and can change the jet direction of the water flow through the spouts to realize the manipulation of the ship. The basic principle of water jet propulsion: it has a certain speed by jetting in the opposite direction of its movement on ships and other aircraft. According to the action force and reaction force, the hull will be subjected to the reaction force of the water flow, and this force is the thrust. [0003] Traditional water jet propulsion is mostly powered by a fuel engine, so the power mechanism must be outside the water, ...

AI Technical Summary

Problems solved by technology

[0003] Traditional water jet propulsion is mostly powered by a fuel engine, so the power mechanism must be outside the water, which limits the installation conditions and is extremely inconvenient. Moreover, the volume is large, the motor and the propeller are separated, and the wiring is complicated, resulting in limited installation. , so there is a need for an integrated mechanism of motor and propeller, which can be completely installed underwater, with faster heat dissipation, while reducing lines and optimizing power transmission
