Description

[0002] In recent years, with the rapid development of the new energy industry, the cost of photovoltaic power generation has been continuously decreasing, accelerating the pace of China's energy transformation. At the same time, building-integrated photovoltaics is a research hotspot in the energy industry, and establishing photovoltaic sheds has become an important development direction for urban outdoor parking lots.

[0003] The existing photovoltaic sheds have relatively single functions and lack management. In addition, being in the harsh outdoor environment for a long time, the hot spot effect caused by the dust accumulated on the surface will lead to a decrease in the power generation efficiency of the entire photovoltaic shed, and even cause local overheating of the photovoltaic components, posing a fire hazard. For this reason, related technologies use power devices such as water pumps to continuously divert water to the photovoltaic components to achieve the cleaning of the photovoltaic components, but the water pumps cause additional energy consumption and are not conducive to energy conservation and emission reduction.

[0028] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] As Figure 1 shown, an embodiment of the present application provides a water-collecting self-cleaning carport, which includes a photovoltaic module, a siphon module, and a collection module.

[0030] Among them, the photovoltaic module is used for photovoltaic power generation. However, during long-term use, the photovoltaic module is prone to dust accumulation, and the hot spot effect caused by dust will lead to a decrease in the power generation efficiency of the photovoltaic module. Therefore, it is necessary to clean the photovoltaic module regularly. The water-collecting self-cleaning carport of the present application uses rainwater to clean the photovoltaic module. The collection module is used to collect rainwater and transport the rainwater to the siphon module. The siphon module continuously transports the rainwater to the photovoltaic module under the siphon action, thereby cleaning the photovoltaic module. At the same time, the water that has cleaned the photovoltaic module also flows into the collection module and cleans the photovoltaic module again in the above manner, so as to achieve the function of cyclic cleaning.

[0031] It can be understood that during the cyclic cleaning process of water, the driving force for water flow is completely provided by the siphon action of the siphon module, and there is no need to additionally set up power devices such as water pumps, thereby reducing energy consumption and being beneficial to energy conservation and emission reduction.

[0032] In some examples, the photovoltaic assembly is used as the roof of the water-collecting self-cleaning carport, including a plurality of photovoltaic panels 101. The photovoltaic panels 101 are arranged in parallel, and mutual shielding between adjacent photovoltaic panels 101 is avoided to ensure that the power generation capacity of each photovoltaic panel 101 is fully utilized. Among them, the number of photovoltaic panels 101 is set according to actual needs, and each photovoltaic panel 101 is arranged in a rectangular array.

[0033] Furthermore, the siphon assembly includes a water storage component 201 and a water storage component 202. The water storage component 201 includes a water storage tank, which is a relatively closed hollow structure. The water storage component 202 includes a water storage tank, which is an open structure with an opening on the top.

[0034] Specifically, the water storage component 201 is connected to the water storage component 202, and the collection component transfers the collected rainwater to the water storage component 202. Water is pre-stored in the water storage component 201. When the photovoltaic module needs to be cleaned, the water storage component 201 transfers the water inside to the photovoltaic module for cleaning. Since the internal space of the water storage component 201 is limited, as the amount of water in the water storage component 201 decreases, the pressure in the water storage component 201 decreases. Under the action of atmospheric pressure, the water in the water storage component 202 will be pressed into the water storage component 201 and used as subsequent cleaning water, that is, the water in the water storage component 202 is transferred to the water storage component 201 by siphon action, without the need to set up an additional power source.

[0035] In some examples, the water storage component 201 is connected to a water spray pipe 203, and the water spray pipe 203 extends from the water storage component 201 to the location of the photovoltaic module. At the same time, the water spray pipe 203 is provided with a plurality of nozzles 204. When the water in the water storage component 201 flows to the location of the nozzles 204, the water will pass through the nozzles 204 and spray onto the surface of the photovoltaic module, thereby completing the cleaning of the photovoltaic module.

[0036] Furthermore, the height of the water storage part 201 is greater than the height of the photovoltaic module, and the water spray pipe 203 extends from the high water storage part 201 to the low photovoltaic module. When the photovoltaic module needs to be cleaned, as long as the water spray pipe 203 is connected, water can flow to the photovoltaic module along the water spray pipe 203 according to its own gravity. It can be understood that when the water flows in the water spray pipe 203, the gravitational potential energy is converted into kinetic energy, ensuring that the water can be sprayed out from the nozzle 204 at a certain speed, thereby improving the cleaning effect of the photovoltaic module.

[0037] In some examples, the water storage component 201 and the water storage component 202 are connected through the water inlet pipe 205, one end of the water inlet pipe 205 is connected to the water storage component 201, and the other end is inserted below the liquid level of the water storage component 202, thereby ensuring that the water in the water storage component 202 can be transported to the water storage component 201 under the siphon effect.

[0038] Among them, the water inlet pipe 205 is connected to the top of the water storage component 201 to prevent the water in the water storage component 201 from flowing back along the water inlet pipe 205 under its own gravity to the water storage component 202. At the same time, the water spray pipe 203 is connected to a position below the liquid level of the water storage component 201, so that the water in the water storage component 201 can only flow out of the water storage component 201 along the water spray pipe 203, thereby determining the direction of water flow and ensuring that all the water can be used for cyclic cleaning.

[0039] In some examples, the water spray pipe 203 is provided with a first valve 301, and the first valve 301 is used to cut off or conduct the water spray pipe 203; the water inlet pipe 205 is provided with a second valve 302, and the second valve 302 is used to inject water into the water storage component 201. During use, first close the first valve 301, open the second valve 302, after injecting water into the water storage component 201 through the second valve 302, close the second valve 302 to ensure that the water inlet pipe 205 is closed. When it is necessary to clean the photovoltaic module, open the first valve 301 to make the water in the water storage component 201 flow into the water spray pipe 203, and the water in the water storage component 202 enters the water storage component 201 under the action of siphonage.

[0040] In some examples, the water storage component 201 and the water storage component 202 are distributed vertically, and the water storage component 201 is located at the top of the water storage component 202. Specifically, a bracket 206 with a certain height is provided at the top of the water storage component 202, and the water storage component 201 is arranged on the bracket 206. Then, there is a certain height difference between the two ends of the water inlet pipe 205 connecting the water storage component 201 and the water storage component 202, and the water in the water storage component 202 needs to overcome its own gravity to be transported to the water storage component 201.

[0041] In some examples, the collection component is used to collect water and introduce the water into the water storage component 202. Among them, the collection component includes a water collection tank 207. To ensure that rainwater can smoothly enter the water collection tank 207, the top of the water collection tank 207 is open.

[0042] Furthermore, the water collection tank 207 is arranged at the edge of the photovoltaic module. It can be understood that the water collection tank 207 is formed in a long strip shape. A bending part is provided at the end of the water collection tank 207, and the bending part extends into the range of the water storage component 202, so as to divert the water to the water storage component 202.

[0043] As Figure 2 shown, in some examples, the water collection and self-cleaning carport further includes a shed frame 401. The shed frame 401 has a certain height to ensure that vehicles can be parked inside the shed frame 401 to realize the basic function of the carport.

[0044] Among them, the photovoltaic module is installed on the top of the shed frame 401. On the one hand, it is used to realize photovoltaic power generation, and on the other hand, it is used to shield the vehicles inside the shed frame 401.

[0045] Furthermore, the top of the shed frame 401 is inclined, so that the photovoltaic modules at the top of the shed frame 401 are also in an inclined state. Due to the inclination of the top of the shed frame 401, there is a side with a larger height and a side with a smaller height at the top of the shed frame 401. The side with a larger height is the cleaning side 402, and the side with a smaller height is the collection side 403. The water spray pipe 203 extends to the cleaning side 402, while the water collection tank 207 is located at the collection side 403.

[0046] It can be understood that during the cleaning process of the photovoltaic modules, the water spray pipe 203 sprays water from a position with a larger height onto the photovoltaic modules, and the water will gradually flow down along the slope of the photovoltaic modules, covering the entire photovoltaic modules to ensure the effectiveness of cleaning. At the same time, when the water flows to the collection side 403, it will automatically enter the water collection tank 207 and be re-transported to the water storage component 202 along the water collection tank 207, making full use of water resources to achieve cyclic cleaning.

[0047] As Figure 3 shown, in some examples, to ensure the stable position of the water spray pipe 203, the photovoltaic module is provided with an installation groove 404. The installation groove 404 extends outward from the photovoltaic module. The top of the installation groove 404 is open, and the water spray pipe 203 is embedded in the installation groove 404. Specifically, the installation groove 404 is a galvanized steel trapezoidal groove.

[0048] Wherein, if the working surface of the photovoltaic module is the top surface, then the top surface of the photovoltaic module needs to be cleaned. For this reason, the diameter of the water spray pipe 203 is larger than the thickness of the photovoltaic panel 101. When the water spray pipe 203 is placed in the installation groove 404, the height of the spray nozzle 204 on the side wall of the water spray pipe 203 is greater than the height of the photovoltaic module, ensuring that the water sprayed along the spray nozzle 204 can accurately reach the top surface of the photovoltaic module.

[0049] In some examples, a number of cross beams 405 are provided at the top of the shed frame 401. Each cross beam 405 is used to support each photovoltaic panel 101, and each photovoltaic panel 101 is installed on the top of each cross beam 405.

[0050] In some examples, the water collection tank 207 is connected to the edge of the photovoltaic module. To further ensure the stable position of the water collection tank 207, the cross beam 405 close to the collection side 403 is connected with a support component 406. The support component 406 extends outward from the shed frame 401, and the support component 406 supports the water collection tank 207 at the bottom of the water collection tank 207. Specifically, the support component 406 is a galvanized steel U-shaped groove to match the shape of the water collection tank 207.

[0051] In the actual implementation process, first, close the first valve 301 and open the second valve 302. Under the initial state, the second valve 302 is used to inject water into the water storage component 201. After the water injection, close the second valve 302. When it is necessary to clean the photovoltaic module, open the first valve 301. The water in the water storage component 201 flows into the spray pipe 203 and is sprayed onto the photovoltaic module along the spray nozzle 204. The water flows down along the slope of the photovoltaic module, thereby cleaning the photovoltaic module. The water flowing to the collection side 403 is collected by the water collection tank 207 and flows back to the water storage component 202, forming a circulation process of the cleaning water. At the same time, the water in the water storage component 202 is replenished into the water storage component 201 under the action of siphonage, continuously providing cleaning water for the photovoltaic module.
