[0003] The patent "a ship propeller residual energy power generation system" (application number: 201210002310.8) achieves the purpose of energy recovery by installing a power generation impeller behind the propeller to recover the wake energy behind the propeller. This invention has obvious deficiencies. First, the huge The water flow is mainly the backward axial flow, which is necessary for the ship to generate power, and the goal of recovering the energy of the axial flow can only weaken the required thrust of the ship, thereby affecting the navigation performance of the ship
Secondly, placing the generator impeller fixing bracket and transmission mechanism i

Example Embodiment

[0019] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:

[0020] Combine Figure 1~5 In the present invention, a rim generator or a ring generator is used to replace the rear stator of the conventional water jet propeller. The rim generator is fixedly installed with the housing of the water-jet thruster. The tail swirl generated by the rotation of the front water pump drives the blades of the rim generator, thereby driving the generator to generate electricity, which can provide additional power for the normal operation of the ship. The distance between the front water pump and the generator impeller is about 0.15 times the diameter of the front propeller.

[0021] figure 1 The overall arrangement of the system equipment is given. The device is composed of an impeller center hub 1, a rim generator or ring generator 2, an inlet pipe 3, a water pump 4 and an impeller 5, etc. The blades of the impeller 5...

Abstract

The invention aims to provide a flange power-generating water-spraying thruster. The thruster comprises an inflow pipeline, a generator, an impeller and a water pump, wherein the water pump is arranged in the inflow pipeline; the generator is mounted on a shall of the inflow pipeline; the impeller connected with the generator is arranged in the inflow pipeline; the inner end parts of the impeller are all connected with an impeller central hub; the impeller and the impeller central hub are arranged at the rear part of the water pump in the inflow direction. The thruster can provide extra electrical energy for the normal operation of a ship; in addition, the impeller can generate beneficial interference on the preposed water pump to improve the propulsion performance and the efficiency; the power generation system has excellent prospects in practical application in the recent context of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a ship device, specifically a ship power generation device. Background technique [0002] The water jet propulsion pump makes a rotary motion, which makes the fluid generate a rotary motion while pushing the fluid backward. Propelling the fluid backwards is necessary for the propeller to generate thrust, while the rotational motion of the wake is a complete waste of energy. [0003] The patent "a ship propeller residual energy power generation system" (application number: 201210002310.8) achieves the purpose of energy recovery by installing a power generation impeller behind the propeller to recover the wake energy behind the propeller. This invention has obvious deficiencies. First, the huge The water flow is mainly the backward axial flow, which is necessary for the ship to generate power, and the goal of recovering the energy of the axial flow can only weaken the required thrust of the ship, thereby affecting the navigation...
