Lying cross-flow horizontal axis roof wind power generation device

Abstract

The invention relates to a lying cross-flow horizontal axis roof wind power generation device which comprises a frame. An impeller and a cross-flow horizontal axis generator are arranged on the frame, the cross-flow horizontal axis generator is coupled with the impeller, and wind collecting guide pipes are arranged at the front end and the rear end of the frame respectively and gradually extend outwards from the frame. The lying cross-flow horizontal axis roof wind power generation device can be simply mounted on various buildings such as a folk house with a pitched roof or a flat roof, a farmhouse, a factory and a warehouse, a wind gathering area is formed by the aid of the area of a wide roof and the wind collecting guide pipes, wind power generation efficiency is improved by multiplied wind speed and wind volume of wind flowing through the impeller, popularization of wind power generation can be promoted, utilization of environment-friendly energy is facilitated, and global carbon emission is decreased.

Description

technical field [0001] The invention relates to a wind power generating device, more specifically, to a lying cross-flow horizontal axis roof wind power generating device. Background technique [0002] According to the placement of the fan shaft, wind power generation devices can generally be divided into two categories: one is horizontal axis wind turbines, and the second is vertical axis wind turbines. Due to the many disadvantages of vertical axis wind turbines in terms of construction cost, daily operation, economic benefits and maintenance, most of the commercial wind turbines are horizontal axis wind turbines. Existing commercial wind power generation devices mostly use multiple large wind turbines to form a power generation system, and the generated electric energy is comprehensively processed and then transmitted to the grid. With the advancement of technology, distributed grid-connected power generation has gradually become a trend, and many small-scale independent...

Problems solved by technology

[0003] Existing wind turbines need to be installed on high towers or poles, and use large-span impellers. The construction cost is high, the power output is not stable, and the efficiency is not high.

Moreover, the wind turbines will generate noise and vibration during operation, which forces the wind turbines to be far away from buildings and many other restrictions, which makes wind power applications rarely used in the household field.
