Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a wind-driven power generating device. [Prior Art] Today, with the scarcity of available resources on the earth and the increasing awareness of environmental protection, the use of renewable energy and low greenhouse gas emissions make the use and development of renewable energy increasingly valued by countries. Solar power and wind power are the most valued. Referring to Fig. 1, a conventional wind power generator includes a support frame u fixed at one end to the ground, a fan 12 fixed to the other end of the support 帛u, and a generator set 13 electrically connected to the fan 12. The fan 12 has a body i2i fixed to the support frame u, and a fan wheel provided on the main body 121 and having three spiral fans 123. The blades 123 are rotated by the wind. The generator set 13 converts the kinetic energy of the rotation of the fan t 123 into electric energy to achieve the effect of generating electricity by wind power. Although the conventional wind power generation device can achieve the effect of generating electricity by wind power, the conventional disadvantages of the wind power generation device i are improved by the following limitations: Large volume: the body 121 of the fan 12 of the conventional wind power generation device The center is about 70 meters away from the ground, and the length of each blade 123 is about 35 meters. It can be seen that the conventional wind power generator is too bulky and can only be installed in a relatively empty space. 1352776 in the city of 'know wind power installations! It is inconvenient to install and use. 2. The power generation efficiency is unstable: the body (2) of the fan of the conventional wind power generation device is solid (4) to increase the structural stability of the support frame u, however, the wind direction is variable and fixed on the support frame. The body 121 of the fan 12 on the u cannot change direction with the wind field, and can only receive power by blowing in a fixed wind direction, so that the blades 123 cannot be blown by the wind (4), resulting in unstable power generation efficiency. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a power generating device capable of collecting wind with a wind direction with a small volume and stable power generation efficiency. In the present invention, the wind power generating device of the present invention comprises a base, a power generating unit disposed in the base, a rotating group, and a set of the rotating group connected to the power generating unit. Projecting on the base, the rotating group has a rotating shaft that can be driven by the wind to drive the power generating unit, and a plurality of blades extending outward from the rotating shaft. The windshield is a rod that is disposed on the base and covers the rotating shaft of the rotating group and the special fan blade and is rotatable relative to the base. The wind collecting cover has a cover, at least—opened in the cover An air inlet, and at least an air outlet opening on the cover body corresponding to the air inlet, wherein the air inlet has a diameter larger than a diameter of the air outlet and when the wind is introduced by the air inlet Each of the blades driving the rotating group rotates in a fixed direction in the _ fixed direction. The effect of the invention is that the windshield is pivoted on the base when the 6 1352776
