[0031] Please refer to Figures 1 to 8 As shown, the present invention discloses a self-cleaning photovoltaic carport, comprising a carport bracket 1, two photovoltaic modules 2 fixed to the carport bracket 1, a cleaning module 3 and a driving module 4 fixed to the carport bracket 1, a receiving space 20 for accommodating the cleaning module 3 is provided between the two photovoltaic modules 2, the cleaning module 3 is connected to the driving module 4, and the driving module 4 is used to control the movement of the cleaning module 3 to clean foreign matter on the surface of the photovoltaic module 2, thereby realizing automatic cleaning of the photovoltaic module.

[0032] In this embodiment, see Figure 1 The driving assembly 4 is used to control the movement of the cleaning assembly 3 along the length direction L of the carport support 1. The two photovoltaic modules 2 are spaced apart along the length direction L of the carport support 1. The space between the two photovoltaic modules 2 forms an accommodation space 20. After the cleaning assembly 3 completes cleaning, the cleaning assembly 3 is parked in the accommodation space 20. Since there is no photovoltaic module 2 in the accommodation space 20, the cleaning assembly 3 does not block the photovoltaic module 2.

[0033] See also Figure 3 The carport bracket 1 includes a roof 11, two support bars 12 arranged on the ceiling 11, a support rod 13 and a base 14. The two photovoltaic modules 2 are fixed to the ceiling 11. The two support bars 12 are correspondingly arranged on the outside of the two photovoltaic modules 2. One end of the support rod 13 is connected to the ceiling 11, and the other end of the support rod 13 is connected to the base 14. The base 14 is used to park new energy vehicles.

[0034] The support bar 12 is indirectly or directly connected to the ceiling 11. The support bar 12 is arranged parallel to the cleaning assembly 3, and the length of the support bar 12 is less than the length of the cleaning assembly 3. In this way, during the cleaning process of the cleaning assembly 3, the support bar 12 is less likely to block dust, allowing dust to fall from the outside of the two photovoltaic modules 2.

[0035] Continue to see Figure 3 The support rod 13 includes a support rod body 131 and a reinforcement rod 132. One end of the support rod body 131 is connected to the ceiling 11, and the other end of the support rod body 131 is connected to the base 14. One end of the reinforcement rod 132 is connected to the ceiling 11, and the other end of the reinforcement rod 132 is connected to the support rod body 131. By providing the reinforcement rod 132, the support strength of the support rod 13 is improved. The support rod body 131 and the reinforcement rod 132 are both configured as curved rods to improve the bending resistance of the support rod 13.

One end of the screw rod 42 is connected to the output shaft, and the other end of the screw rod 42 is rotatably connected to the other support bar 12. In this embodiment, the screw rod 42 is opposite to one edge 211 of the frame 21, and the screw rod 42 does not block the photovoltaic panel 22. Optionally, the drive member 41 is a motor.

[0039] See also Figures 3 to 5 The cleaning assembly 3 includes a cleaning brush 31 and a support frame 32. The cleaning brush 31 is connected to the support frame 32, and a screw rod 42 is inserted into a screw hole 320 of the support frame 32. During the cleaning process, the driving member 41 controls the screw rod 42 to rotate, and the screw rod 42 drives the support frame 32 and the cleaning brush 31 to move, and the cleaning brush 31 cleans the photovoltaic panel 22.

[0040] In this embodiment, see Figure 5 The support frame 32 includes a first support block 321, a second support block 322, and a connecting plate 323 connecting the first and second support blocks 321 and 322. The first support block 321 is provided with a screw hole 320. The ends of the cleaning brush 31 are respectively connected to the first and second support blocks 321 and 322 in a floating manner. This reduces damage to the photovoltaic panel 22 caused by the cleaning brush 31 during the cleaning process, thereby protecting the photovoltaic panel 22.

[0041] Further, see Figures 6 to 8The first support block 321 is provided with a first groove 301 and a second groove 302 connected to the first groove 301. The second support block 322 is provided with a third groove 303 and a fourth groove 304 connected to the third groove 303. The cleaning brush 31 includes a cleaning brush body 311 and two end portions 312 connected to the cleaning brush body 311.
