Combined wind guide device for wind power generation with narrow tube

Abstract

The invention relates to a combined type air guiding device for narrow pipe air-gathering wind power generation. The combined type air guiding device for narrow air-gathering wind power generation is arranged in a narrow pipe; an impeller is arranged in the center of the narrow pipe; the narrow pipe comprises a front narrow pipe and a rear narrow pipe; the air guiding device comprises a front air guiding cone, a rear air guiding cone and a tail end fairing cone; the front air guiding cone is arranged in the center of the front narrow pipe; the rear air guiding cone and the tail end fairing cone are arranged in the center of the rear narrow pipe; the rear air guiding cone is positioned between the front air guiding cone and the tail end fairing cone; a plurality of first air guiding plates are symmetrically arranged between the outer wall of the front air guiding cone and the inner wall of the front narrow pipe; air guiding racks are respectively arranged between the outer wall of the rear air guiding cone and the outer wall of the tail end fairing cone and between the outer wall of the rear air guiding cone and the inner wall of the rear narrow pipe; the structure of the front air guiding cone is consistent to that of the rear air guiding cone; each of the front air guiding cone and the tail end fairing cone consists of a framework and a shell on the framework; and each shell consists of a plurality of plates which are combined together. The combined type air guiding device for narrow pipe air-gathering wind power generation has the advantages of light weight, high strength, high air guiding efficiency and high effect.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a wind gathering wind power generation system, in particular to a narrow tube wind gathering wind power generation system. Background technique [0002] Narrow-tube wind-gathering wind power generation system has attracted more and more attention because of its unique wind-gathering structure, pressure boosting and speed-up function, and high-efficiency power output performance. The applicant retrieved a large number of existing patents on narrow tube wind power generation, such as: patent number: ZL201420079694.8, a straight-through narrow tube wind power generation system; patent number: ZL205879644.X, a double-duct axial flow The above-mentioned patents mostly disclose the basic structure and principles required for narrow-tube wind-gathering power generation systems. From the contents disclosed in the above patents, it can be known that the wind guide...

AI Technical Summary

Problems solved by technology

From the contents disclosed in the above patents, it can be seen that the wind guide structure is mainly plate type and integrated type. This structural feature is easy to manufacture and is suitable for small narrow tubes and low-power generator sets. However, when it is applied to large narrow tubes and high-power generator sets , there will be problems such as high requirements for integral molding, large volume, heavy weight, and difficulty in transportation and installation.
