VERTICAL AXIS WIND TURBINE

摘要

Each wind tower integrated in a set is a metallic structure constituted by four vertical columns, connected by modulated elements (Z) which centralise several wind turbines of vertical axis; the said turbines have got a common rotation shaft (X), which drives a hydrostatic pump (HP), Figure 1. The turbines preferably have four shovels, each shovel is constituted by two metallic window frames which support a plug (V), symmetrically connected to a shaft (Y), Figure 4, whose rotation is synchronised with the rotation of the said common rotation shaft (X). A safety system, applied in each shovel, and including the devices (P1), (M1) and (P2), (M2), regulates the turbines rotation speed, performing the progressive coiling of the plugs according to the increase in the wind speed and its pressure on the plugs, Figures 3, 4, 5 and 6. A system of strength transmission is obtained by a hydrostatic circuit (HL), which connects the said hydrostatic pumps (HP) to a hydrostatic engine (MP), which drives an electrical generator (G), Figure 2.
