[0030] Please refer to Figures 1 to 7 , and now the photovoltaic carport provided by the present invention will be described. A photovoltaic carport includes a mounting frame 1, a cooling module 2 and a fire extinguishing module 3; the mounting frame 1 is used for mounting a photovoltaic module 5, a charging device 4 is arranged on the mounting frame 1 and is located below the photovoltaic module 5; the cooling module 2 includes a cooling plate member 21 and a circulation plate member 22; the cooling plate member 21 is arranged on the mounting frame 1 and is laid below the photovoltaic module 5; the cooling plate member 21 is provided with a cooling cavity 211, and the cooling cavity 211 is connected to a water storage tank; the circulation plate member 22 is arranged above the photovoltaic module 5, the circulation plate member 22 is provided with a circulation cavity 221, and both ends of the circulation cavity 221 are respectively communicated with both ends of the cooling cavity 211, and the circulation cavity 221 and the cooling cavity 211 form a cooling flow channel 222 for circulating cooling water; a plurality of water spray holes 23 communicating with the cooling cavity 211 are provided on the lower end surface of the cooling plate member 21; a plurality of nozzles 31 and detectors 32 are arranged on the fire extinguishing module 3, the plurality of nozzles 31 are respectively installed in the plurality of water spray holes 23, and the spraying direction of the nozzles 31 is set towards the charging device 4; the detector 32 is arranged on the mounting frame 1 and is electrically connected to the nozzle 31, and is used for detecting whether a fire occurs in the charging device 4 and controlling the nozzle 31 to spray cooling water.
[0031] Compared with the prior art, for the photovoltaic shed provided in this embodiment, when in use, since the cooling plate member 21 provided on the mounting frame 1 is laid under the photovoltaic module 5, and the cooling plate member 21 is provided with a cooling cavity 211, and at the same time, the circulation plate member 22 provided above the photovoltaic module 5 is provided with a circulation cavity 221, and both ends of the circulation cavity 221 are respectively communicated with both ends of the cooling cavity 211, and the circulation cavity 221 and the cooling cavity 211 form a cooling flow channel 222 for circulating cooling water. Therefore, after connecting the cooling cavity 211 with the water storage tank, the cooling water sequentially passes through the cooling flow channel 222 formed by the cooling cavity 211 and the circulation cavity 221, so that the cooling plate member 21 laid under the photovoltaic module 5 dissipates heat from the photovoltaic module 5; since a plurality of water spraying holes 23 communicating with the cooling cavity 211 are provided on the lower end surface of the cooling plate member 21, and a plurality of nozzles 31 are respectively installed in the plurality of water spraying holes 23, and at the same time, the spraying direction of the nozzles 31 is set towards the charging device 4, and the detector 32 provided on the mounting frame 1 is electrically connected to the nozzles 31. Therefore, when the detector 32 detects a fire in the charging device 4, the detector 32 controls the nozzles 31 to spray the cooling water in the cooling flow channel 222 towards the charging device 4, thereby extinguishing the fire in time; in this way, by means of the cooling flow channel 222 formed by the cooling plate member 21 and the circulation plate member 22 on the cooling module 2, the cooling water flows in the cooling flow channel 222, thereby cooling the photovoltaic module 5; at the same time, the detector 32 on the fire extinguishing module 3 is used to detect the charging device 4 at any time, and after a fire occurs in the charging device 4, the detector 32 timely controls the nozzles 31 to spray the cooling water towards the charging device 4, so as to extinguish the fire as soon as possible.
[0032] Please refer to Figure 1 and Figure 3 As a specific implementation manner of the photovoltaic shed provided by the present invention, a communication port 24 communicating with the cooling flow channel 222 is provided on the cooling plate member 21, a partition plate 25 is provided in the communication port 24, and the partition plate 25 divides the communication port 24 into a water inlet 241 and a water outlet 242 arranged up and down; both the water inlet 241 and the water outlet 242 are communicated with the water storage tank; since the partition plate 25 divides the communication port 24 into a water inlet 241 and a water outlet 242 arranged up and down, and both the water inlet 241 and the water outlet 242 are communicated with the water storage tank, in order to make the cooling water circulate in the cooling flow channel 222, the cooling water is pumped from the water inlet 241 into the cooling flow channel 222 through a water pump, the cooling water flows in the cooling flow channel 222 and flows out through the water outlet 242, and finally flows back into the water storage tank; in this way, by means of the water inlet 241 and the water outlet 242, the cooling water circulates in the cooling flow channel 222, thereby cooling the photovoltaic module 5.
[0033] Please refer to Figure 1 and Figure 3As a specific embodiment of the photovoltaic carport provided by the present invention, the partition 25 has the freedom to rotate along the inner wall of the connecting port 24 to block or open the water inlet 241 and the water outlet 242; a driver 26 is provided on the cooling plate 21, and the driver 26 is rotatably connected to the partition 25 to drive the partition 25 to rotate; when there is no sun at night, the photovoltaic module 5 usually does not work, and naturally there is no need for the cooling module 2 to cool it; after the water pump is turned off, in order to ensure that the water in the cooling channel 222 does not flow back into the water tank, resulting in no cooling water or insufficient cooling water in the cooling channel 222 when a fire occurs, the partition 25 is rotatably connected to the inner wall of the connecting port 24, and at night, the driver 26 is used to drive the partition 25 to rotate to close the connecting port 24, and then the water inlet 241 and the water outlet 242 are closed, thereby preventing the cooling water from flowing back into the water tank; the driver 26 is a motor, and the output shaft of the motor is transmission-connected to the partition 25.
[0034] The fire extinguishing module 3 is also provided with a signal processor, which is electrically connected to multiple nozzles 31 and a detector 32. The detector 32 is a flame sensor.

When a fire occurs in the charging device 4, the detector 32 converts the brightness of the flame into a level signal and sends the signal to the signal processor. The signal processor identifies the signal and opens the nozzle 31 to allow cooling water to enter the nozzle 31, thereby causing the nozzle 31 to spray cooling water toward the charging device 4.
[0035] See also Figure 7 As a specific embodiment of the photovoltaic carport provided by the present invention, the width of the circulation plate 22 is smaller than the width of the photovoltaic module 5; the width of the circulation plate 22 is set to be smaller than the width of the photovoltaic module 5, so as to expose the photovoltaic module 5 and allow the photovoltaic module 5 to be irradiated by sunlight, thereby storing energy.
[0036] See also Figure 1 As a specific embodiment of the photovoltaic carport provided by the present invention, a plurality of accommodating grooves 212 are further provided on the cooling plate 22 for accommodating a plurality of photovoltaic modules 5; the photovoltaic modules 5 are installed with the help of the accommodating grooves 212, which not only makes the fixing effect of the photovoltaic modules 5 more reliable, but also reduces the distance between the photovoltaic modules 5 and the cooling water in the cooling channel 222, thereby increasing the cooling effect of the cooling water on the photovoltaic modules 5, so that the cooling module 2 can cool down the photovoltaic modules 5 more quickly.
[0037] See also Figure 1 , Figure 4 and Figure 6, as a specific implementation of the photovoltaic shed provided by the present invention, a photovoltaic shed further includes a cleaning component 6. The cleaning component 6 is arranged on the circulating plate member 22 and is located between the circulating plate member 22 and the photovoltaic module 5 for cleaning the photovoltaic module 5. Since the upper end surface of the photovoltaic module 5 is exposed for a long time, the photovoltaic module 5 is very likely to be contaminated with dust. Therefore, the cleaning component 6 is arranged between the circulating plate member 22 and the photovoltaic module 5, and the cleaning component 6 is used to clean the photovoltaic module 5.
[0038] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , as a specific implementation of the photovoltaic shed provided by the present invention, a water injection port 27 communicating with the circulation cavity 221 is formed on the circulating plate member 22. The cleaning component 6 includes a water injection pipe 61, a cleaning brush 62 and a driving member 63. A plurality of water leakage holes 611 are provided on the water injection pipe 61. One end of the water injection pipe 61 is open and the other end is closed, and the open end of the water injection pipe 61 corresponds to the water injection port 27. The cleaning brush 62 is sleeved on the water injection pipe 61. The driving member 63 is arranged on the mounting frame 1, and the free end of the driving member 63 is in transmission connection with the water injection pipe 61 for driving the water injection pipe 61 to move so that the cleaning brush 62 cleans the photovoltaic module 5. Since a water injection port 27 communicating with the circulation cavity 221 is formed on the circulating plate member 22, and the open end of the water injection pipe 61 corresponds to the water injection port 27, and at the same time, a plurality of water leakage holes 611 are provided on the water injection pipe 61, and the cleaning brush 62 is sleeved on the water injection pipe 61, when the cleaning component 6 is used to clean the photovoltaic module 5, the cooling water in the circulation cavity 221 enters the water injection pipe 61 through the water injection port 27, and then the cleaning brush 62 is wetted through the plurality of water leakage holes 611 on the water injection pipe 61. Since the driving member 63 is arranged on the mounting frame 1 and the free end of the driving member 63 is in transmission connection with the water injection pipe 61, the water injection pipe 61 is controlled to move along the arrangement direction of the photovoltaic modules 5 by means of the driving member 63, so that the cleaning brush 62 wetted by the cooling water cleans the upper end surface of the photovoltaic module 5, thereby cleaning the photovoltaic module 5 clean. The driving member 63 is a cylinder, and the free end of the cylinder is in transmission connection with the water injection pipe 61.
[0039] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, as a specific implementation of the photovoltaic shed provided by the present invention, the cleaning assembly 6 is further provided with a connecting member 66. The connecting member 66 is arranged at the open end of the water injection pipe 61 to facilitate the rapid entry of cooling water into the water injection pipe 61. The water injection port 27 is of a conical structure, and the larger opening end of the water injection port 27 is arranged close to the water injection pipe 61. The connecting member 66 includes two limiting plates 661, a connecting pipe 662 and an elastic member 663. The two limiting plates 661 are arranged in parallel and at intervals inside the water injection pipe 61. The limiting plate 661 close to the water injection port 27 is slidably connected to the inner wall of the water injection pipe 61, and the limiting plate 661 far from the water injection port 27 is fixedly connected to the inner wall of the water injection pipe 61. The connecting pipe 662 passes through the two limiting plates 661 and is arranged inside the water injection pipe 61. One end of the connecting pipe 662 extends into the water injection port 27. The connecting pipe 662 is fixedly connected to the limiting plate 661 close to the water injection port 27 and is slidably connected to the limiting plate 661 far from the water injection port 27. The elastic member 663 is sleeved on the connecting pipe 662, and both ends of the elastic member 663 are fixedly connected to the two limiting plates 661 respectively. When the driving member 63 controls the water injection pipe 61 to move forward, the connecting pipe 662 moves forward with the water injection pipe 61. Since the water injection port 27 is of a conical structure and the larger opening end of the water injection port 27 is arranged close to the water injection pipe 61, after the connecting pipe 662 contacts the inner wall of the water injection port 27, as the connecting pipe 662 moves, the connecting pipe 662 is forced to retract into the water injection pipe 61. At the same time, the connecting pipe 662 drives the limiting plate 661 to move, thereby compressing the elastic member 663. When the driving member 63 drives the water injection pipe 61 to retract, the connecting pipe 662 retracts with the water injection pipe 61. When the connecting pipe 662 moves to the position of the water injection port 27, the elastic member 663 returns to its original position by means of its elastic force, thereby pushing the limiting plate 661 and the connecting pipe 662 to return to their original positions, so that one end of the connecting pipe 662 quickly extends into the water injection port 27, so that the cooling water quickly enters the water injection pipe 61 through the connecting pipe 662. The elastic member 663 is a spring.
