Description
Technical field
What the present invention relates to is a kind of marine installation, specifically boats and ships electricity generating device.
Background technique
Hydraulic jet propulsion water pump rotates, and when propelling fluid moves backward, fluid has been produced and rotatablely moves.It is that propulsion device generation thrust is necessary that propelling fluid moves backward, and rotatablely moving of wake flow is a kind of energy dissipation completely.
Patent " a kind of propeller for vessels power generating by remain energy system " (application number: 201210002310.8) realize by wake energy after installing electricity generation impeller additional at oar rear and reclaiming propeller cavitation the object that energy reclaims, this invention exists significantly not enough, first after oar, huge current are mainly axial flow backward, this axial flow is that boats and ships generation power is necessary, the energy that reclaims this axial flow of take can only weaken the required thrust of boats and ships as target, thereby affects the navigation performance of boats and ships.Secondly, after generator impeller fixed support and driving mechanism are placed in ship, current can increase additional friction.
For propeller wash rotating energy, reclaiming comparatively desirable device is Grim impeller, and Grim impeller blade divides turbine section and propeller cavitation section, diameter is generally 1.15～1.3 times of bow oar diameter, diameter is very large, but blade is narrow and thin, the strength of materials is required to too harshness, with regard to current material technology level, be also difficult to produce desirable Grim impeller.
Hydraulic jet propulsion is eliminated water pump generation conventionally tailspin by install stator additional at water pump rear flows, but effect is not remarkable especially.Vigorously advocating now under the large background of energy-saving and emission-reduction, exploitation becomes the Main Topics of ship energy saving for reclaiming the device of hydraulic jet propulsion water pump wake flow rotating energy.
Summary of the invention
The object of the present invention is to provide and realize the wheel rim generating hydraulic jet propulsion that wake flow rotating energy is converted into electric energy.
The object of the present invention is achieved like this:
Wheel rim generating hydraulic jet propulsion of the present invention, it is characterized in that: comprise influent stream pipeline, generator, impeller, water pump, water pump is arranged in influent stream pipeline, generator is arranged on influent stream conduit enclosure, the impeller being connected with generator is arranged in influent stream pipeline, each impeller inner end all connects impeller center hub, and in influent stream direction, impeller and impeller center hub are arranged on water pump rear.
The present invention can also comprise:
