The light intensity sensor 34, the light angle sensor 35, the dust sensor 36 and the remote data transmission module 37 are all electrically connected to the single-chip microcomputer.

[0083] When working, the single chip microcomputer uses the data feedback of the light intensity sensor 34 and the light angle sensor 35 to adjust the pitch angle of the mounting frame 1 and the rotation angle of the BIPV photovoltaic panel body 28 in real time, and then continuously maintains the high luminous efficiency of the BIPV photovoltaic panel body 28;

[0084] Through the setting of the remote data transmission module 37, on the one hand, the single chip microcomputer can accept the real-time control of the central remote terminal, and on the other hand, the relevant data of the bracket can be remotely transmitted to the external remote control terminal;

When in working state, the photovoltaic cleaning module and the BIPV photovoltaic panel body 28 are staggered, thereby effectively reducing the influence of the photovoltaic cleaning module on the power generation efficiency of the BIPV photovoltaic panel body 28;

[0089] When severe hail or sandstorm weather occurs, the front of the steel guard plate 27 faces upward and the BIPV photovoltaic panel body 28 faces downward, thereby achieving self-protection of the BIPV photovoltaic panel body 28, so as to effectively reduce the probability of damage to the BIPV photovoltaic panel body 28 in severe weather;

[0090] When it is necessary to self-clean the BIPV photovoltaic panel body 28, in the first cleaning stage, the BIPV photovoltaic panel body 28 faces upward, the top surface of the BIPV photovoltaic panel body 28 protrudes from the reciprocating frame 5, and the first motor outputs the speed at a set power. After the first motor outputs the speed, the torsion spring 21, the second gear 20 and the half-face gear a15 are set, so that the gear shaft a16 and the driving wheel 19 can reciprocate within the set period. After the driving wheel 19 reciprocates within the set period, it drives the annular carrier 3 to move back and forth left and right within the set stroke. By setting the specifications of the half-face gear a15 and the second gear 20, the unidirectional displacement stroke of the annular carrier 3 is 1.3 times the length of the BIPV photovoltaic panel body 28.

In the second cleaning stage, the carrier plate 25 rotates at a set speed. When the BIPV photovoltaic panel rotates, the air cleaning nozzle 32 discharges high-pressure air, thereby realizing the centrifugal self-removal and air-cleaning removal of impurities and dust on the BIPV photovoltaic panel body 28, thereby improving the surface cleanliness and power generation efficiency of the BIPV photovoltaic panel body 28. After the first motor works, through the setting of the limit spring 6 and the driven gear plate 18, the half-face gear b23 outputs the speed, and the reciprocating frame 5 can drive the BIPV photovoltaic panel body 28 to move back and forth within the set stroke. After the reciprocating frame 5 moves back and forth left and right, the impurities and dust on the BIPV photovoltaic panel body 28 can be self-shaken off in the cleaning mode.
