摘要:
The invention relates to an apparatus that is aimed at generation of electrical energy by means of assembly of two, three, or four shaped wings, which turn on a vertical shaft coupled to an alternator or magnet. More specifically, the invention is constituted by a shaft having different heights according to the desired power, the aforesaid shaft preferably being made of aluminium alloy or steel, to which two, three, or four volutes are welded, developing on the basis of annuli that satisfy a precise mathematical formula that enables "winding" thereof along the shaft through a given number of degrees. Furthermore, the invention comprises two, three, or four wings with monocentric inner profile and polycentric outer profile arranged from the base attachment to the top.

A gear pump unit for hydroelectric power generation comprises a generator (138) and a control module operatively connected to a gear pump (131). The gear pump (131) comprises a case (131B) with a fluid inlet (132) and an outlet (135). A first rotor (133) comprises a first plurality of radially spaced teeth (133A, 133B, 133C) that wrap around the first rotor helically in a clockwise direction. A second rotor (134) comprises a second plurality of radially spaced teeth (134A, 134B, 134C) that wrap around the second rotor helically in a counter-clockwise direction. The first plurality of teeth mesh with the second plurality of teeth. The gear pump unit operates in a pump, turbine, or siphon mode via the control module 150 selectively rotating the first and second rotors. Electricity is generated by coupling the rotational energy of the first and second rotors to the generator (138).

The present invention relates to a wind power generation system. Said system is an array of a number of wind power generation units on the supporting tower, each wind power generation unit is formed by one vertical axis wind rotor and one or more power generation unit(s), in which the rotation shaft of the wind rotor is coupled with the rotor shaft of the single generator set through a connector, or the rotation shaft of the wind rotor is connected with the rotor shafts of multiple generator sets through the transmission mechanism. The present invention proposes a helical vertical axis wind rotor and a lineal vertical axis wind rotor constructed by the drag type blade and the lift type blade, and proposes a helical wind rotor with pure drag type blade as well as the disassembling and splicing design of the above wind rotor. The present invention is similar to a "building block" power generation unit whose design could be optimized according to the wind field to reach megawatts scale power output. Furthermore, by adjusting the number of the generator sets connected with the single wind rotor in the power generation unit, the starting load of the wind rotor can be lowered on the one hand, on the other hand this can load proper number of generator sets with small power by disengaging and engaging at real time according to the varying conditions of the wind speed. The manufacture, transportation, installation and maintenance of said power generation unit are relatively easier and it can resist larger wind disaster, thus being of higher safety.
