Shaftless screw gear power generation device

Abstract

Disclosed is a shaftless screw gear generating device which can convert motive power into electrical energy. Moreover, the conversion efficiency is much increased relative to a traditional steam engine set, a steam-electric generating set, a water turbine set and a turbine set, and meanwhile, the defect in the prior art, such as turbine surge and shaft wear, is compensated. The shaftless screw gear generating device improves the point of action of the motive power, the action route of force and the transmission mode and improves the composition of a generating structure and a control system, namely that the spiral principle of rotating force for rotating a radial rotor (2) by axial thrust is used and the rotor is embedded into the centre of a hollow axial sensing unit of a shell (6). In this way, the volume of the entire generating space is reduced, the material use is reduced, the maintenance workload is reduced and automatic control can react quickly. Meanwhile, the shaftless screw gear generating device has the characteristics of no coupling, no leakage, automatic brake, extendible performance, no maintenance and long service life. The motive power here is not limited to water energy, wind energy, ocean energy, burning thermal energy and thermal energy of nuclear reactions.

Description

Technical field [0001] The patent of the present invention relates to a shaftless screw wheel power generation device, which can convert the driving force into electric energy, and the conversion efficiency is much higher than that of the traditional steam unit, steam turbine unit, water turbine unit, and turbine unit, and at the same time makes up for other problems in the existing power generation technology. Defects such as shaft wear, turbine surge. It is realized by improving the action point of the motive force, the action route of the force, the transmission mode of the force and the improvement of the power generation structure and the composition of the control system, that is, the helical principle of using the axial pressure of the motive force to drive the rotation of the helical wheel rotor (screw wheel for short), and Embedding the rotor in the center of the hollow axial induction unit also reduces the size of the entire power generation space, reduces material c...
