Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic carports, and particularly relates to a photovoltaic carport structure with a waterproof function. Background Technique

[0002] Through the photovoltaic building integration technology, the solar photovoltaic panels are integrated into the building. Different from the form of attaching to the building, the photovoltaic carport is both a building component of the carport and has the function of using solar energy to generate electricity.

[0003] The structure of the photovoltaic carport mainly consists of photovoltaic panels, columns, crossbeams, and purlins. The crossbeams are fixed on the columns, the purlins are fixed on the crossbeams, and the photovoltaic panels are installed on the crossbeams through the purlins. As the top structure of the photovoltaic carport, due to the installation characteristics requirements of the photovoltaic array components, there is a certain spacing between the photovoltaic panels. When the photovoltaic carport is in use, in rainy weather, the rainwater accumulated on the surface of the photovoltaic panels will drip down from the gap between two adjacent photovoltaic panels. As a rainproof device for the parking lot, the carport needs to have a waterproof function, that is, the inside of the carport cannot leak. Traditionally, sealing materials are usually used to fill the gaps between the photovoltaic panels on the photovoltaic carport. For example, sealing materials are used for caulking, such as filling sealant and stuffing rubber sealing strips, so as to achieve the waterproof purpose. The existing waterproof methods of the photovoltaic carport have the following deficiencies:

[0004] 1) Since the rubber sealing strip will accelerate aging when heated for a long time, eventually resulting in poor sealing, and water dripping inside the carport on rainy days, affecting the original function of the carport to protect from wind and rain, and at the same time inducing the risk of charging equipment getting water.

[0005] 2) The sealant has an aging problem. After being exposed to wind, sun, and rain for a long time, the sealant is damaged and needs to be repaired repeatedly. The carport is generally relatively high, and working at heights often poses a safety risk. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1-7As shown in the figure, Embodiment 1 of the present utility model provides a photovoltaic carport structure with a waterproof function. The photovoltaic carport structure includes a photovoltaic module 1, a steel structure support 2, and a supporting steel purlin 3. The supporting steel purlin 3 is fixed below the photovoltaic module 1, and the supporting steel purlin 3 is installed above the steel structure support 2.

The photovoltaic module 1 includes a number of photovoltaic panels 11. The number of photovoltaic panels 11 are spliced and fixed at intervals. There is a gap formed between two adjacent photovoltaic panels 11. A number of main water diversion troughs 4 are provided between the number of photovoltaic panels 11 and the supporting steel purlin 3. The number of main water diversion troughs 4 are fixed at the upper end of the supporting steel purlin 3 at intervals and are located below the gap between two adjacent photovoltaic panels 11. A secondary water diversion trough 5 is provided between two adjacent main water diversion troughs 4. The secondary water diversion trough 5 is fixed below the lateral edge of each photovoltaic panel 11. The number of photovoltaic panels 11 are fixed obliquely above the steel structure support 2. A high position part is formed on one side of each photovoltaic panel 11, and a low position part is formed on the other side of each photovoltaic panel 11. An anti-overflow fold 51 is fixed at one end of the secondary water diversion trough 5. The anti-overflow fold 51 of the secondary water diversion trough 5 is located at the low position part of the photovoltaic panel 11. The photovoltaic carport of the present utility model installs the main water diversion trough 4 and the secondary water diversion trough 5 through the supporting steel purlin 3. After the rainwater flowing down from the gap of the photovoltaic panel 11 is collected by the main water diversion trough 4 through the secondary water diversion trough 5 in the transverse direction of the photovoltaic panel 11 and converged into the longitudinal main water diversion trough 4, the rainwater is then discharged centrally to ensure the waterproof effect of the photovoltaic carport structure. The main water diversion trough 4 of the present utility model can be installed in a concealed manner below the photovoltaic module 1 and is supported and fixed by the original support structure of the photovoltaic module 1, that is, the supporting steel purlin 3, without the need to install an independent support, which is convenient for support. The photovoltaic module 1 is installed obliquely on the steel structure support 2. The secondary water diversion trough 5 is provided to collect the rainwater flowing down from the gap of the photovoltaic panel 11. The anti-overflow fold 51 of the secondary water diversion trough 5 is installed on the low position side of the adjacent photovoltaic panel 11 to prevent the impact overflow caused by excessive rainwater.
