The vertical louvers 4 are placed on the outside of the curtain wall 10 through the support frame 1 fixed on the upper and lower parts of the curtain wall 10, and the surface of the vertical louvers 4 is attached with a solar photoelectric film 3, and the solar photoelectric film 3 is connected to the battery 8 through the controller 7; The current generated by the film 3 is input to the controller 7 through the wire, and after being transformed by the controller, it is output to the battery 8 to charge the battery 8; the tubular motor 2 installed in the vertical louver rotating shaft is electrically connected to the battery 8 through the wire; The tubular motor 2 is also connected with the signal of the calculator 9; when the vertical louver 4 needs to rotate, the battery 8 supplies the tubular motor 2 with electric power to drive the vertical louver 4 to rotate. The solar radiation probe 5 and the temperature probe 6 are respectively installed on the top of the vertical sun visor 4, and the solar radiation probe 5 and the temperature probe 6 are respectively connected to the calculator 9 for signals, and the outdoor real-time solar radiation and air temperature data sensed respectively are transmitted to the calculator 9. Calculator 9 analyzes the data of solar radiation and air temperature, and then compares it with the upper limit of outdoor solar radiation and outdoor air temperature set by the user. If it is greater than the value set by the user, it is judged that shading is needed; otherwise, the Shade is not required. The user sets the outdoor solar radiation and the upper limit of the outdoor temperature based on the indoor temperature. For example, if the indoor air conditioner temperature is 26°C, when the outdoor air temperature exceeds 26°C, it should be judged that sunshade is needed. If sunshade is needed, calculate the solar azimuth at the current moment by calculator 9, and control the tubular motor 2 in the vertical louver 4 to rotate at the azimuth through the data line, and then control the rotation of the vertical louver 4 to make the vertical louver 4 The surface on which the photoelectric film 3 is attached is always facing the incident direction of the sun, which can realize sunshade and collect solar energy at the same time. The calculator repeats the above process of detection, judgment and control every 10 to 60 minutes to ensure that the sun visor is always at the best shading angle, and at the same time convert solar energy into electrical energy for use by the system itself and other electrical equipment.

As shown in Figure 2, Figure 5a, 5b, and 5c, the vertical louver 4 includes an "M" shaped vertical louver skeleton 11, an inverted "V" shaped gusset 12, a rotating shaft 13, an arc connector 14 and an arc Aluminum plate 15; the vertical louver frame 11 is connected through the connecting piece 14, the rotating shaft 13 runs through the connecting piece 14 from top to bottom, and the buckle plate 12 is fastened to the frame 11 from both sides to play the effect of decorating the louver plate. 15 is fixed on the sun visor frame 11, and the solar photovoltaic film 3 is pasted on the outside of the arc-shaped aluminum plate to form an integrated structure of solar cells and sun louvers.

As shown in Figure 4, the support frame includes a first connection plate 4-1 and a second connection plate 4-3 perpendicular to each other; the first connection plate 4-1 is provided with a plurality of bolt holes 4-2, and the support frame 1 is connected by bolts. It is fixed on the curtain wall 10; the second connecting plate 4-3 is provided with a through hole 4-4, and is connected with the vertical louver 4 by bolts. The curtain wall 10 needs to reserve a slot for fixing the first connecting plate 4-1 during production, and insert the first connecting plate 4-1 of the support frame 1 into the reserved slot while installing the curtain wall 10, and use The bolts are fixed, and the second connecting plate 4-3 is used for installing the vertical louver 4, and the vertical louver 4 is fixed on the support frame 1 by bolts.

As shown in Figure 3, the solar radiation probe 5 and the air temperature probe 6 collect outdoor solar radiation and air temperature data every 10 minutes (also can be 60 minutes, or any time of 10-60 minutes), and send them to the calculator 9. The calculator 9 compares the received solar radiation and air temperature data with the upper limit of outdoor solar radiation and outdoor air temperature set by the user. If it is greater than the value set by the user, it is judged that sunshade is needed; otherwise, the Shade is not required. If sunshade is not needed, go back to the previous step to continue data collection; if sunshade is needed, calculate the angle at which the louvers should rotate based on the local latitude and longitude and the year, month, and day. The vertical louver 4 rotates so that the surface of the vertical louver 4 attached to the photoelectric film 3 is always facing the incident direction of the sun, which can realize sunshade and collect solar energy at the same time.

This product is a flexible thin film amorphous silicon solar cell, which can be bent, with ethylene propylene copolymer adhesive and microbial inhibitor on the back, and can be pasted on the metal louver superior. The controller 10 can choose the Phocos CXN solar charge and discharge controller from Phocos, the tubular motor 3 can choose the BM series tubular motor produced by Shenzhen Grand Precision Motor Co., Ltd., the solar radiation probe 8 can choose the LI200X silicon radiation meter, and the temperature A copper-constantan thermocouple can be used for the probe, and a programmable single-chip microcomputer can be used for the calculator, which is used to collect solar radiation and temperature data, judge whether sunshade is needed, and control the rotation angle of the tubular motor.

At present, most of the commonly used external sunshade products are fixed sunshade structures. This structure can achieve the effect of sunshade in summer, but at the same time, it affects the quality of indoor lighting. In addition, fixed sunshade will also affect the needs of users for sunlight in winter, reducing the comfort of the indoor occupants. The movable sunshade structure is an effective way to solve this problem, but the current movable sunshade needs to consume extra power, and does not have intelligent control capabilities, which reduces the energy-saving rate of the sunshade. The solar-driven vertical louver sunshade device of the present invention can intelligently adjust the deflection angle of the sunshade louvers according to the outdoor meteorological parameters, block solar radiation in hot summer, reduce the power consumption of air conditioners, and can pass sunlight in cold winter, improving the safety of personnel indoors. Comfort, in addition, the present invention does not need to consume additional power, and the power for the louvers to rotate comes from the photoelectric film attached to the surface of the sun visor, which can further improve the energy-saving potential of the sun-shading structure, and the energy-saving rate can reach about 18%, while the ordinary external sun-shading structure saves energy The rate is around 6%.
