vertical shaft wind group and combined group that includes wind power plant

摘要

It is described a vertical axis wind group (1) that comprises a first vertical axis turbine (2) with a first rotation axis (XI) and at least one second vertical axis turbine (3) with a second rotation axis (X2) functionally associated in series to the first turbine (2). A protection carter (4) associated with the first (2) and second turbine (3) conformed to keep free and exposed to the wind a first portion (50) of each turbine, and to coat and to insulate by the wind a second portion (60), opposite to the first portion (50) is provided. The protection carter (4) comprises at least one conveying duct (5, 6) obtained in the second portion (60) that fluidically connects the first (2) and second turbine (3) such that when a primary wind flow (7, 7') hits the first portion (50) generates an active rotation of the blades of the turbine, and a conveyed wind flow (7a", 7b") that crosses the second portion (60) and is conveyed by the conveying duct (5, 6) between the second turbine (3) towards the first turbine (2), in order to generate an additional thrust the primary wind flow (7, 7' ), increasing the efficiency of the wind group (1) ·
