Background
Wind power generation has certain requirements on wind speed, the wind speed is generally required to be higher than the rated wind speed of 10 meters per second, and the lowest generated wind speed also needs to reach 4 meters per second; breeze with the wind speed lower than 3 meters per second is unavailable power generation wind energy; but the wind energy which can not be utilized on the earth accounts for about 70 percent of the whole wind energy resource; in recent years, some research and experiment projects for generating electricity by using breeze have appeared, for example: the wind gathering cylinder is arranged by utilizing the Venturi principle to gather wind for generating electricity, breeze is introduced into a Venturi tube from a large opening at the upper end of the Venturi wind gathering cylinder, the entering breeze is accelerated by the change of the inner diameter of a cylinder opening of the wind gathering cylinder, and the accelerated breeze is used for driving a wind driven generator to generate electricity; the technical scheme mainly utilizes the principle of converting potential energy into kinetic energy of air, has the defects of unobvious breeze acceleration, non-sustainable wind after acceleration, poor wind gathering effect and the like, and cannot utilize breeze to continuously generate electricity; for another example: the patent number 2021112094298, entitled "breeze energy-gathering wind power generation device", discloses a cylindrical cover body base (induced draft guide chamber), a conical drainage bulge is arranged in the middle of the bottom surface of the induced draft guide chamber, a venturi-shaped draft tube is connected to the top surface of the induced draft guide chamber, an air flow mixing low-speed section, an air flow mixing uniform high-speed section and an air flow discharging deceleration section are sequentially arranged in the draft tube from bottom to top, and a wind driven generator is arranged in the air flow mixing uniform high-speed section; the device is used as a wind source of a breeze power generation device, and has the important two links of effective introduction amount of breeze and airflow and diversion and transmission to a wind pulling barrel; how to introduce breeze in the external environment into the induced draft diversion chamber to the greatest extent (namely, increase the air density), and how to minimize the wind energy loss of the introduced breeze (namely, the breeze introduced into the induced draft tube does not generate vortex, turbulent flow and cross flow as much as possible), and the breeze is redirected upwards to enter the draft tube, is effectively utilized to generate electricity, and is a difficult problem to be further researched and solved; the invention patent with the patent number 2021112094298 discloses a breeze leading-in blade on the excircle facade of an induced draft guide chamber, which consists of an outer blade plate, a middle blade plate and an inner blade plate, wherein the middle blade plate is a flexible soft plate, and the middle blade plate is connected between the outer blade plate and the inner blade plate;
