DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the drawings.

[0014] Embodiment: A multifunctional photovoltaic carport system, as Figure 1 - Figure 2 shown, includes a column 1 and a purlin 2. The rear end of the purlin 2 is fixedly connected to the top of the column 1. A hook-shaped water spray pipe 3 is provided at the front end of the purlin 2. The water outlet end of the hook-shaped water spray pipe 3 extends to the upper end of the purlin 2 and the outlet is arranged backward. A water receiving trough 4 is provided at the rear end of the purlin 2. A water storage tank 5 is provided on each of the left and right sides of the column 1. A connecting pipe 6 is connected between the lower ends of the front sides of the two water storage tanks 5. A water connection pipe 7 is connected between the water receiving trough 4 and the left water storage tank 5. One end of the overflow pipe 12 is connected to the top of the water storage tank 5 and the other end extends to the bottom of the column 1. A water pump 8 is provided at the top of the front side of the column 1. A liquid extraction pipe 9 is provided at the water inlet end of the water pump 8. The other end of the liquid extraction pipe 9 extends into the bottom of the right water storage tank 5. A liquid outlet pipe 10 is connected to the liquid outlet of the water pump 8. The other end of the liquid outlet pipe 10 is connected to the hook-shaped water spray pipe 3.

[0015] Two connecting plates 11 are provided at the middle position of the water receiving trough 4. The water receiving trough 4 is connected to the rear end of the purlin 2 through the two connecting plates; the purlin 2 has a structure that is smaller at the front and larger at the rear; an overflow pipe 12 is provided at the upper end of the rear side of the left water storage tank 5.

[0016] Principle of the utility model: During use, multiple groups of columns 1 are arranged in parallel. The photovoltaic panels are installed on purlins 2. The spacing between the columns 1 is set according to the length of the water receiving trough 4. Rainwater on the photovoltaic panels flows into the water receiving trough 4 on rainy days, and then flows into the left water storage tank 5 through the water connecting pipe 7 and into the right water storage tank 5 through the communicating pipe 6. The rainwater in the water storage tank 5 is sprayed out from the hook-shaped water spray pipe 3 by the water pump 8, thus realizing the cleaning of the photovoltaic panels;

[0017] By setting the overflow pipe 12, when the rainwater in both water storage tanks 5 reaches the height of the overflow pipe 12, the excess rainwater will flow out from the overflow pipe 12.
