A structure device for direct-drive speed-up narrow-tube wind-gathering power generation

Abstract

The invention relates to a framework device for wind collection power generation of a direct-drive accelerated type narrow tube. The framework device comprises a hub type component. One end of the hub type component is fixedly connected with the inner ring of a swing bearing. The other end of the hub type component is fixedly connected with one end of a tubular support. A tubular supporting hoop is arranged on the periphery of the tubular support in a matched manner. One end of the tubular supporting hoop is fixedly connected with a reinforced composite bridge through a gasket and a fastener. One end of a double-rail structure frame is fixedly connected with the tail portion of the reinforced composite bridge, and the other end of the double-rail structure frame is connected with the hub type component in a clamping manner. The end, connected with the hub type component, of the tubular support penetrates the reinforced composite bridge. According to the framework device, damage possibly caused by turbulent flow and gust vibration in the whole machine operation process is avoided, the key function is achieved on decomposing and eliminating of gravity loads, and the framework device is as firm as a rock even in severe wind conditions; and the framework device effectively adapts to application and popularization of large-power wind generation type wind power generators in the future.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a direct-drive speed-increasing narrow-tube wind-collecting frame device for power generation. Background technique [0002] At present, as far as traditional wind power generation is concerned, its technology is not mature enough and has many shortcomings, especially in the construction of power stations, low wind speed start-up and distributed applications. Invest a large amount of money in the construction of long-distance transmission lines, such as the recently launched "four AC and four direct" UHV project construction, with an investment of 173.7 billion yuan. [0003] In order to overcome the above-mentioned problems of traditional wind power generation, a new type of wind power generation technology such as narrow tube wind power generation is derived. Compared with vertical axis wind turbines, it has the advantages of gathering wind energy, increasing pre...

Problems solved by technology

[0004] It takes the front structure of the generator (in the wind guide cone) as the main body, and the rear type is also self-contained with the hub-type circumferential support as an option. This layout method is indeed compact in structure, takes up little space, and has little influence on fluid movement. and strong adjustability, etc., but it fails to overcome the damage caused by turbulence and gust vibration during the operation of the whole machine, and cannot be applied to severe wind conditions. Therefore, from the perspectives of comprehensive technology, safety and easy industrial production Considering that it is necessary to innovate again for the high-power application of narrow-tube wind-gathering wind power generation, and fully complete the technical accumulation of core equipment
