A suction type wind energy collection and power generation system and its use method

Abstract

The invention discloses a suction type wind energy collection and power generation system and its application method. The system includes a wind energy collection device, a wind power generation device and connecting pipelines. The wind energy collection device includes a base, a support column and a wind energy collection shell. The wind energy collection The shell is provided with two oppositely arranged first openings and second openings. The longitudinal cross-sectional area of ​​the wind energy collection shell first gradually decreases and then gradually increases from the first opening to the second opening. The inner surface of the wind energy collection shell is circumferentially upward There are multiple air extraction through holes, and there is a gap between two adjacent air extraction through holes. The connecting pipeline includes an inner pipeline and an outer pipeline. Multiple air extraction through holes are arranged along the extension direction of the inner pipeline, and the inner pipeline passes through Pipeline and wind power plant connections. The wind energy collection device and the wind power generator of the present invention are relatively independent, are easy to install, have high reliability, improve adaptability to complex weather, have good expansibility, and are effectively suitable for installation in small spaces or complicated areas.

Description

Technical field [0001] The present invention belongs to the technical field of wind power generation, in particular to a suction type wind energy collection and power generation system and the method of use thereof. Background [0002] Distributed wind power generation system is mainly used in rural areas, pastoral areas, mountainous areas, developing large, medium and small cities or commercial areas near the construction, to solve the local user electricity demand, when these application scenarios appear low average wind speed, complex environment, limited space and other restrictions, the traditional wind power generation technology and equipment can not be used, the need for small wind power generation technology to achieve. But there are still some problems with the current power generation system: [0003] First, the wind energy gathering device and the power generation device in the power generation system are integrated as a whole, the structure is relatively complex, and...

AI Technical Summary

Problems solved by technology

[0003] First, the wind energy gathering device and the power generation device in the power generation system are integrated as a whole, the structure is relatively complicated, and the overall cost is relatively high;

[0004] Second, the wind energy collection device and the power generation system are interrelated, and the size between the two is not a simple scaling relationship, which is not conducive to the distributed arrangement of multi-unit modules in areas with small spaces or complex environments;

[0005] Third, the wind energy harvesting device contains rotating blade structures, which are exposed high-speed rotating parts, which will cause problems such as shaft strength, lubrication and maintenance. In addition, if they are arranged in occupied areas such as buildings, there is a risk of injury
