Therefore, the overhead sun-proof layer is equivalently arranged on the building roof, the space between the photovoltaic solar panel 2 and the building roof is utilized to play the roles of heat preservation, heat insulation and sun protection, and particularly, the indoor temperature of the top floor can be effectively reduced in summer.

As shown in the left side of fig. 3, the worm and gear device includes a full worm gear 221 fixedly installed on the rotating shaft 22 and coaxially disposed, a first worm 222 engaged with the full worm gear 221, and a first motor 223 in transmission connection with the first worm 222, wherein the full worm gear 221 is a worm gear with 360 degrees of circumference surface for engagement.

During the use, two sets of worm gear device synchronous operation can drive photovoltaic solar panel 2 and do 360 degrees rotations. Of course, a limiting mechanism may be provided as required to limit the maximum deflection angle of the photovoltaic solar panel 2.

Another worm gear arrangement is shown on the right side of fig. 3. The worm and gear device comprises an incomplete worm wheel 211 fixedly connected to the back of the bottom plate 21, a second worm 212 meshed with the incomplete worm wheel 211 and a second motor 213 in transmission connection with the second worm 212, wherein the incomplete worm wheel 211 is of a semicircular ring structure with meshing teeth on the outer ring surface. The incomplete worm wheel 211 of each semicircular ring structure has two support points on the back of the bottom plate 21, so that the weight of the photovoltaic solar panel 2 can be better supported. Although the deflection angle is less than plus or minus 45 degrees, it is also fully sufficient for photovoltaic solar panels 2 that do not require too large a deflection angle. When the device is used, the two ends of the photovoltaic solar panel 2 are respectively provided with one group of worm gear device, the worm gear device synchronously operates, and the forward deflection or the reverse deflection of the photovoltaic solar panel 2 is controlled through the forward rotation or the reverse rotation of the motor II 213. Two ends of the second worm 212 are arranged on the shaft seats through bearings, and the shaft seats are fixed on the inner side wall of the roof wind-break wall 3 below the second worm 212. One end of the second worm 212 is connected with a second motor 213 through a coupler, and the second motor 213 is also fixedly installed on the inner side wall of the roof wind-break wall 3. The photovoltaic solar panel 2 above the second worm 212 can prevent rainwater erosion, and the service life is prolonged. Of course, in order to better protect the second worm 212 and the second motor 213, a container such as a cover can be covered on the worm.

In actual use, the deflection direction and angle of the photovoltaic solar panel 2 are adjusted according to the weather conditions. As shown in fig. 4, in the daytime of summer, strong sunlight is directly irradiated to the ground as shown by double-line arrows in the drawing, at the moment, the photovoltaic power generation and sun shading functions are mainly used, the deflection mechanism adjusts the photovoltaic solar panel 2 to be in a horizontal state, the large-area photovoltaic solar panel 2 almost shields the whole roof, and a gap between the photovoltaic solar panel 2 and a floor slab becomes a good ventilation and heat insulation layer, so that the temperature in the top-floor room can be effectively reduced. In this case, only photovoltaic power generation is sufficient regardless of wind, and therefore, the wind direction and the wind power do not need to be considered. Of course, the power of the two clean energy sources can be combined if there is sufficient wind power to generate, as indicated by the single-line arrows in the figure.

Wind-powered electricity generation photovoltaic sunshade integration building structure has two kinds of new forms of energy acquisition means of wind power generation and photovoltaic power generation to can reach the purpose that improves new forms of energy utilization ratio, extension new forms of energy live time, improvement new forms of energy input-output ratio through the different mode of gesture conversion that changes photovoltaic solar panel 2 according to the transform of weather and illumination condition.

Wind power and photovoltaic power generation are complementary, so that the utilization rate of new energy can be improved by about one time, meanwhile, the effect of balancing a power generation power curve can be achieved, particularly, the compensation of wind power generation can achieve a good balancing effect at the power consumption peak at night, and the dependence on power utilization of a power grid is reduced. As shown in fig. 9, the horizontal axis represents the time of day and the vertical axis represents the power output change. The thin solid line in the figure represents the output power P1 of the photovoltaic solar panel 2, and the photovoltaic solar panel 2 only has power output in the time period between 6 o ' clock and 18 o ' clock and reaches the output peak value around 12 o ' clock in 24 hours a day; the dotted line in the figure represents the output power P2 of the wind driven generator 1, and the wind has power output in 24 hours all day long; the power of the two is superposed, the total active output time is prolonged, and the power curve P3 is relatively flat, so that the power generation quality is effectively improved.

As shown in fig. 5 and 6, in the case of night in summer or cloudy day, the photovoltaic solar panel 2 does not output power because of insufficient illumination. At this time, the inclination direction of the photovoltaic solar panel 2 needs to be adjusted according to the wind direction. As shown in fig. 5, when a wind blows in the south, as shown by the arrow of the single line in the figure, the airflow direction is from right to left, the photovoltaic solar panel 2 should be adjusted to have a high right end and a low left end, and the inclined photovoltaic solar panel 2 and the roof wind-blocking walls 3 on both sides form a horn mouth facing the wind, so that the airflow velocity below the photovoltaic solar panel 2 can be increased, and the power generation efficiency of the wind driven generator 1 can be improved. Similarly, as shown in fig. 6, when a north wind is blown, the airflow direction is from left to right, and at this time, the photovoltaic solar panel 2 can be adjusted to have a high left end and a low right end, so that the wind driven generator 1 can still obtain a good power generation efficiency. The deflection angle of the photovoltaic solar panel 2 in the above-mentioned service condition can be adjusted at any time according to the principle that the optimal power generation efficiency is obtained according to the size of wind power. The two modes are flexibly used, electric energy can be output all day long under an ideal state, and the defect of a single power generation mode is overcome.

As shown in fig. 7, photovoltaic power generation is still dominant during the winter day, but the light incidence angle is small in this season, as shown by the double-line arrow in the figure. At this time, the photovoltaic solar panel 2 should be adjusted to make the front surface with the photovoltaic panel 23 face the south, and the inclination angle is determined by the sunshine angle. At this time, the change of the wind direction and the wind power does not affect the posture of the photovoltaic solar panel 2.

As shown in fig. 8, in the case of nights in winter or cloudy days, wind power generation is mainly used. At this moment, the photovoltaic solar panel 2 loses the power generation capacity, and the posture of the photovoltaic solar panel 2 is adjusted according to the change of the wind direction. The principle is the same as that of fig. 5 and 6.

The control circuits and the working principles of the first motor 223 and the second motor 213, and the working principles of the wind power generation circuit, the photovoltaic power generation circuit and the inverter circuit thereof are all the prior art, and are not described again.
