[0052] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0053] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0054] As described in the background section, existing photovoltaic charging carports still pose certain safety hazards in practical applications. In particular, during the charging process, if an overload, malfunction, or other unexpected situation occurs and a fire breaks out, once a fire starts in one parking space, the fire will spread to other parking spaces, causing damage to all the vehicles in the carport and potentially leading to a larger safety accident, resulting in loss of life and property.

[0055] Example 1

[0056] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a photovoltaic charging carport, such as... Figure 1 As shown, the carport includes a carport frame 10 and a photovoltaic roof 40. The photovoltaic roof is installed on top of the carport frame, and a charging pile 30 is installed inside the carport frame. Figure 3 , 4 As shown, the carport frame includes:

[0057] Beam 13;

[0058] Purlin 12, the purlin is set between two adjacent beams in each group of beams, at least one purlin is set between two adjacent beams, at least one purlin is arranged along the length direction of the beam, the upper surface of the purlin is flush with the upper surface of the beam, and the photovoltaic canopy is fixed to the upper surface of the beam and the purlin.

[0059] Support column 11 is erected on the ground and fixedly connected to the beam.

[0060] This embodiment reduces the space between the photovoltaic canopy roof and the purlins and beams by placing the purlins between two adjacent beams and making the upper surface of the purlins flush with the upper surface of the beams. This reduces the risk of flames from a vehicle burning under the canopy being transmitted to adjacent parking spaces.

[0061] In this embodiment, as Figure 1 As shown, the carport may also include a smoke curtain 50, which is installed on the upper part of the carport frame and is equidistantly arranged along the length of the carport frame.

[0062] By designing smoke curtains between parking spaces, it is possible to effectively isolate the chain fire caused by an accidental fire during the charging of electric vehicles. In daily life, it can also be used as an advertising board.

[0063] In this embodiment, the carport also includes a fire extinguishing structure, which is installed inside the carport.

[0064] In this embodiment, the carport also includes a cooling system installed on top of the carport frame. The cooling system includes a heat exchange device to cool the charging pile.

The fire hydrant is connected to a fire water source. A fire hydrant pipe box can also be installed inside the carport, and the fire hydrant pipe is equipped with a fire hydrant pipe inside.

[0066] In addition, the fire extinguishing structure can also be configured by installing multiple boxes containing fire extinguishers inside the carport. By opening the boxes, fire extinguishers can be taken out and manually operated to extinguish the fire.

[0067] In addition to the methods described above, the fire extinguishing structure may also employ other devices capable of achieving fire extinguishing functions.

[0068] Example 2:

[0069] This embodiment provides one of the fire extinguishing structures described in Embodiment 1, such as... Figure 3 As shown, the fire extinguishing structure in this embodiment is a sprinkler system 70, which is fixedly installed on the top of the carport frame;

[0072] The nozzle 72 is connected to the spray pipe 71, and at least one nozzle is provided between adjacent smoke curtains.

[0073] When a fire breaks out, the power supply to the charging station is cut off, and the sprinkler pipes are connected to the water source. Water is sprayed through the nozzles to extinguish the fire, thereby preventing the fire from spreading.

[0074] In this embodiment, the carport may also include a water collection system, which is entirely buried underground and is used to collect liquids discharged from the sprinkler system and the cooling system.

[0075] like Figure 5 As shown, the water collection system includes:

[0076] A drainage ditch 100 is installed underground. A second cover plate 90 is provided on the top of the drainage ditch.
