[0024] Advantages of the present invention:

[0025] 1. When the present invention works, it can realize the self-cleaning, self-protection of the BIPV photovoltaic panel body and the two-way self-adjustment of the layout angle. When self-cleaning of the BIPV photovoltaic panel body is required, in the first cleaning stage, the front side of the BIPV photovoltaic panel body faces upward, and the top surface of the BIPV photovoltaic panel body protrudes from the reciprocating frame. The first motor outputs a rotational speed at a set power. After the first motor outputs the rotational speed, through the settings of the torsion spring, the second gear, and the semi-face gear a, the tooth shaft a and the driving wheel can reciprocally rotate within a set period. After the driving wheel reciprocally rotates within a set period, it drives the annular carrier belt to reciprocally move left and right within a set stroke. By setting the specifications of the semi-face gear a and the second gear, the one-way displacement stroke of the annular carrier belt is 1.3 times the length of the BIPV photovoltaic panel body. Through the above displacement stroke setting, the all-round cleaning of the BIPV photovoltaic panel body is realized. And when the first motor works, the realization of the reciprocating displacement effect of the annular carrier belt can realize the repeated cleaning of the surface of the BIPV photovoltaic panel body, thereby improving the cleaning effect of the BIPV photovoltaic panel body. In the second cleaning stage, the carrier plate rotates at a set speed. When the BIPV photovoltaic panel body rotates, the air cleaning spray holes eject high-pressure air, thereby realizing the centrifugal self-throwing and air cleaning removal of impurities and dust on the BIPV photovoltaic panel body, and then improving the surface cleanliness and power generation efficiency of the BIPV photovoltaic panel body. And after the first motor works, through the settings of the limit spring and the driven tooth plate, after the semi-face gear b outputs the rotational speed, the reciprocating frame can drive the BIPV photovoltaic panel body to reciprocally move left and right within a set stroke. After the reciprocating frame reciprocally moves left and right, in the cleaning mode, the impurities and dust on the BIPV photovoltaic panel body can be self-shaken off. Through the realization of the above vibration self-dusting effect, the cleaning effect and cleaning intensity during the cleaning of the BIPV photovoltaic panel body can be effectively improved.

[0026] 2. In the present invention, when severe hail or sandstorm weather occurs, the steel guard plate faces upward and the BIPV photovoltaic panel body faces downward, thereby realizing the self-protection of the BIPV photovoltaic panel body and effectively reducing the damage probability of the BIPV photovoltaic panel body in bad weather.

[0027] 3. When the present invention works, the single-chip microcomputer adjusts the pitch angle of the mounting bracket and the rotation angle of the BIPV photovoltaic panel body in real time through the data feedback of the light intensity sensor and the light angle sensor, so as to continuously maintain the high luminous efficiency of the BIPV photovoltaic panel body.

[0055] A set of limit springs 6 are fixedly mounted on both sides of the reciprocating frame 5, and the limit springs 6 are connected to the mounting frame 1. The reciprocating frame 5 is driven by two linkage components and moves back and forth left and right within a set stroke;

[0056] A group of photovoltaic modules distributed in a linear array is installed on the reciprocating frame 5;

[0057] A second motor is mounted on the reciprocating frame 5, the output shaft end of the second motor is drivingly connected to the first chain belt, and each photovoltaic module is drivingly connected to the first chain belt;

[0058] The two linkage components both include a half-face gear a15 fixed on the transmission shaft 2, a gear shaft a16 and a gear shaft b17 rotatably connected to the mounting frame 1, and a driven gear plate 18 fixed to the bottom surface of the reciprocating frame 5;

[0059] A driving wheel 19 and a second gear 20 are fixedly mounted on the gear shaft a16, respectively. The second gear 20 is in transmission connection with the half-face gear a15. A torsion spring 21 is fixedly mounted at the rotation connection between the gear shaft a16 and the mounting frame 1.

[0060] Four driven wheels 22 are rotatably connected to the side of the mounting frame 1, and the driving wheel 19 and the four driven wheels 22 are all connected to an annular carrier belt 3 at the corresponding position.

[0061] By setting the torsion spring 21, the second gear 20 and the half-face gear a15, the gear shaft a16 and the driving wheel 19 can reciprocate within a set period;

[0062] The radius of the half-face gear a15 is 10 times the radius of the second gear 20;

[0063] After the driving wheel 19 reciprocates within a set period, the endless carrier belt 3 is driven to reciprocate left and right within a set stroke;

[0064] By setting the specifications of the half-face gear a15 and the second gear 20, the one-way displacement stroke of the annular carrier 3 is 1.3 times the length of the BIPV photovoltaic panel body 28. By setting the displacement stroke, the BIPV photovoltaic panel body 28 can be cleaned in all directions. When the first motor is working, the annular carrier 3 can move back and forth to achieve repeated cleaning of the surface of the BIPV photovoltaic panel body 28, thereby improving the cleaning effect of the BIPV photovoltaic panel body 28.

[0065] In the non-cleaning mode, the photovoltaic cleaning module and the BIPV photovoltaic panel body 28 are staggered, thereby effectively reducing the impact of the photovoltaic cleaning module on the power generation efficiency of the BIPV photovoltaic panel body 28;

[0066] The gear shaft b17 is connected to the transmission shaft 2 through the second chain belt, and a half-face gear b23 is fixedly mounted on the gear shaft b17, and the half-face gear b23 is connected to the driven gear plate 18;

[0067] When the gear shaft a16 rotates, the gear shaft b17 rotates synchronously. After the gear shaft b17 rotates, it drives the half-face gear b23 to rotate. After the half-face gear b23 rotates, the limit spring 6 and the driven gear plate 18 are set so that the half-face gear b23 outputs the rotation 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, the impurities and dust on the BIPV photovoltaic panel body 28 can be self-shaken in the cleaning mode. The above-mentioned vibration self-shaking dust effect is achieved to effectively improve the cleaning effect and cleaning intensity of the BIPV photovoltaic panel body 28 when cleaning;

[0068] The photovoltaic cleaning module includes a cleaning frame 10, which is fixedly connected to two annular carriers 3, and two brush shafts 11 are rotatably connected to the cleaning frame 10, and positive spiral bristles 12 and reverse spiral bristles 13 are respectively fixedly installed on the two brush shafts 11, and the spiral directions of the positive spiral bristles 12 and the reverse spiral bristles 13 are opposite, and two first gears 14 are fixedly installed on the brush shaft 11, and the two first gears 14 are respectively connected to the two fixed gear plates 4 in a transmission manner;

[0069] When the annular carrier tape 3 reciprocates within the set stroke, through the transmission connection structure between the fixed tooth plate 4 and the first gear 14, the brush shaft 11 can rotate. After the two brush shafts 11 rotate, they drive the positive spiral bristles 12 and the reverse spiral bristles 13 to rotate. After the positive spiral bristles 12 and the reverse spiral bristles 13 rotate, they clean the surface of the BIPV photovoltaic panel body 28 bidirectionally. Through the realization of the bidirectional cleaning effect of the BIPV photovoltaic panel body 28, the cleaning intensity of the BIPV photovoltaic panel body 28 can be effectively improved;

[0070] Through the spiral structure of the positive spiral bristles 12 and the reverse spiral bristles 13, when the BIPV photovoltaic panel body 28 is being cleaned, the impurities cleaned out can be automatically discharged outward;

[0071] By setting the spiral directions of the positive spiral bristles 12 and the reverse spiral bristles 13 to be opposite, bidirectional cleaning during the cleaning of the BIPV photovoltaic panel body 28 is achieved;

[0072] The photovoltaic module includes a carrier cavity 24 opened on the reciprocating frame 5. A carrier plate 25 is arranged inside the carrier cavity 24. Rotating shafts 26 are installed on both side surfaces of the carrier plate 25. Both rotating shafts 26 are rotatably connected to the reciprocating frame 5. One rotating shaft 26 is in transmission connection with the first chain belt. A steel guard plate 27 is fixedly installed on the back surface of the carrier plate 25, and a BIPV photovoltaic panel body 28 is installed on the front surface of the carrier plate 25;

[0073] A set of positioning and installation holes for installing and positioning the BIPV photovoltaic panel body 28 are opened on the front surface of the carrier plate 25;

[0074] The rotation axis direction of the rotating shaft 26 is parallel to the reciprocating displacement direction of the reciprocating frame 5, and the axis of the air cleaning spray hole 32 is perpendicular to the axis of the rotating shaft 26;

[0075] When the BIPV photovoltaic panel body 28 is working normally, the BIPV photovoltaic panel body 28 faces upward, and the BIPV photovoltaic panel body 28 is at a set angle under the action of the single-chip microcomputer. By maintaining the angle of the BIPV photovoltaic panel body 28, the power generation efficiency of the BIPV photovoltaic panel body 28 is maintained;

[0076] When the BIPV photovoltaic panel body 28 needs to be cleaned, the carrier plate 25 rotates at a set speed during the set cleaning stage. When the BIPV photovoltaic panel rotates, the air cleaning spray hole 32 emits high-pressure air, so as to realize the centrifugal self-throwing and air cleaning of impurities and dust on the BIPV photovoltaic panel body 28, and then improve the surface cleanliness and power generation efficiency of the BIPV photovoltaic panel body 28;

[0077] When severe hail or sandstorm weather occurs, the steel guard plate 27 faces upward and the BIPV photovoltaic panel body 28 faces downward, thereby realizing self - protection of the BIPV photovoltaic panel body 28 and effectively reducing the damage probability of the BIPV photovoltaic panel body 28 in bad weather;

[0078] The high - pressure air cleaning mechanism includes an air - blowing cylinder 29 fixed to the bottom surface of the mounting frame 1. A group of air - blowing blades 30 distributed in a circumferential array are installed on the transmission shaft 2 corresponding to the inner side of the air - blowing cylinder 29.

An air - guiding cavity communicating with the air - outlet hose 31 is fixedly opened inside the reciprocating frame 5, and two groups of symmetrically arranged air - cleaning spray holes 32 communicating with the air - guiding cavity are opened inside each loading cavity 24;

[0079] During the cleaning mode, the air - blowing cylinder 29 blows high - pressure air, and the air - cleaning spray holes 32 emit high - pressure air. After the air - cleaning spray holes 32 emit high - pressure air, high - pressure air cleaning of the BIPV photovoltaic panel body 28 is realized;

[0080] The electric control module is installed on the reciprocating frame 5 and electrically controls and adjusts the working states of the photovoltaic module and the mounting frame 1.

[0081] The electric control module includes a central control box 33 fixed to the reciprocating frame 5. A single - chip microcomputer is fixedly installed inside the central control box 33. A light intensity sensor 34, a light angle sensor 35, a dust sensor 36 and a remote data transmission module 37 are respectively installed on the central control box 33. 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.

[0082] During operation, the single - chip microcomputer adjusts the pitching angle of the mounting frame 1 and the rotation angle of the BIPV photovoltaic panel body 28 in real time through the data feedback of the light intensity sensor 34 and the light angle sensor 35, and then continuously maintains the high luminous efficiency of the BIPV photovoltaic panel body 28;

[0083] Through the setting of the remote data transmission module 37, on the one hand, the single - chip microcomputer can receive real - time control from the central remote terminal, and on the other hand, the relevant data of this bracket can be remotely transmitted to the external remote control terminal;

[0084] Through the setting of the dust sensor 36, the external remote terminal can monitor the dust - covering degree of the BIPV photovoltaic panel body 28;

[0085] The light intensity sensor 34, the light angle sensor 35, the dust sensor 36, the remote data transmission module 37 and the single - chip microcomputer can all be customized or selected according to actual needs.

[0086] The working principle of the present invention is that both the remote data transmission module 37 and the single-chip microcomputer are electrically connected.

[0087] During operation, the single-chip microcomputer adjusts the pitching angle of the mounting frame 1 and the rotation angle of the BIPV photovoltaic panel body 28 in real time through the data feedback of the light intensity sensor 34 and the light angle sensor 35, so as to continuously maintain the high luminous efficiency of the BIPV photovoltaic panel body 28. In the working state, the photovoltaic cleaning module is arranged out of alignment with the BIPV photovoltaic panel body 28, thereby effectively reducing the influence of the photovoltaic cleaning module on the power generation efficiency of the BIPV photovoltaic panel body 28;

[0088] When severe hail or sandstorm weather occurs, the front side of the steel guard plate 27 faces upward and the BIPV photovoltaic panel body 28 faces downward, thereby realizing the self-protection of the BIPV photovoltaic panel body 28 and effectively reducing the damage probability of the BIPV photovoltaic panel body 28 in bad weather;

[0089] When self-cleaning of the BIPV photovoltaic panel body 28 is required, in the first cleaning stage, the front side of the BIPV photovoltaic panel body 28 faces upward, and the top surface of the BIPV photovoltaic panel body 28 protrudes from the reciprocating frame 5. The first motor outputs a rotational speed at a set power. After the first motor outputs the rotational speed, through the settings of the torsion spring 21, the second gear 20 and the semi-face gear a15, the tooth shaft a16 and the driving wheel 19 can reciprocally rotate within a set period. After the driving wheel 19 reciprocally rotates within a set period, the annular carrier belt 3 is driven to reciprocally move left and right within a set stroke. By setting the specifications of the semi-face gear a15 and the second gear 20, the one-way displacement stroke of the annular carrier belt 3 is 1.3 times the length of the BIPV photovoltaic panel body 28. Through the above displacement stroke setting, the all-round cleaning of the BIPV photovoltaic panel body 28 is realized. Moreover, when the first motor works, the reciprocating displacement effect of the annular carrier belt 3 can realize the repeated cleaning of the surface of the BIPV photovoltaic panel body 28, thereby improving the cleaning effect 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 spray holes 32 eject high-pressure air, thereby realizing the centrifugal self-throwing and air cleaning removal of impurities and dust on the BIPV photovoltaic panel body 28, and then improving the surface cleanliness and power generation efficiency of the BIPV photovoltaic panel body 28. After the first motor works, through the settings of the limit spring 6 and the driven tooth plate 18, after the semi-face gear b23 outputs the rotational speed, the reciprocating frame 5 can drive the BIPV photovoltaic panel body 28 to reciprocally move left and right within a set stroke. After the reciprocating frame 5 reciprocally moves left and right, in the cleaning mode, the impurities and dust on the BIPV photovoltaic panel body 28 can be self-shaken off. Through the realization of the above vibration self-dusting effect, the cleaning effect and cleaning intensity during the cleaning of the BIPV photovoltaic panel body 28 are effectively improved.
