Abstract
After one common water energy utilizing machine, screw propeller or water turbine, one or more stages of screw propeller or water turbine are connected serially while one set of synchronous change gears is mounted for synchronizing the output rotation speed and transmitting the kinetic energy to the main output shaft. The present invention has best utilization of water energy.
Description
Affiliated technical field
The present invention relates to a kind of method of utilizing the water energy.
Background technique
At present, known water can utilized device be by propeller cavitation or water turbine the mechanical energy that the kinetic energy of water is converted into propeller cavitation or water turbine rotation to be used again.In order to guarantee higher output speed, just need the final velocity after the water work done can not be too little, so just make water still bigger to the speed after propeller cavitation or the water turbine work done, this explanation has still been contained sizable mechanical energy and has not been utilized in tail water, cause the waste of hydraulic power potentials.
Summary of the invention
In order to overcome the deficiency that existing water energy utilized device can't make full use of the water energy, the invention provides a kind of way that more makes full use of the water energy.
The technological scheme that the present invention solves its technical problem is: can utilize after machinery is propeller cavitation or water turbine at common water, above secondary spiral oar or the water turbine of series connection one-level, thus the working principle of secondary spiral oar or water turbine is to make its output speed with the output speed of higher level's propeller cavitation or water turbine is consistent kinetic energy be passed to main output shaft by one group of synchromesh change gear.Make secondary spiral oar or water turbine can the total output of utilized device make contributions to water.With same principle connect thereafter more secondary spiral oar or water turbine, level off to the downstream flow velocity until final tail water speed, thereby reach more make full use of water can purpose.
The invention has the beneficial effects as follows to have higher water energy utilization ratio by utilized device than existing water, reduce the waste of hydraulic power potentials.
