Description

Technical Field

[0001] This application relates to the field of photovoltaic energy-saving technology, and in particular to an ecological photovoltaic self-cleaning water storage carport. Background Technology

[0002] Against the backdrop of global energy structure transformation and increased environmental awareness, solar energy, as a clean and renewable energy source, is finding increasingly widespread applications. Photovoltaic carports, a product of green innovation, are gradually moving from concept to reality, becoming an important force driving sustainable development.

[0003] A photovoltaic (PV) carport is a parking facility that integrates a solar photovoltaic power generation system. It possesses the sunshade and rain protection functions of a traditional carport, while also converting solar energy into electricity through solar photovoltaic modules, achieving energy self-sufficiency. The core of a PV carport lies in photovoltaic power generation technology. The photovoltaic modules absorb sunlight to generate direct current (DC), which is then converted into alternating current (AC) by an inverter to power lighting, monitoring systems, charging stations, and other equipment within the carport.

[0004] However, in practical applications, the photovoltaic panels on the roof of the photovoltaic carport tend to accumulate dust, which can affect the photoelectric conversion efficiency of the photovoltaic panels, indicating room for improvement. Utility Model Content

[0005] To address the issue of dust accumulation on the photovoltaic panels at the top of a photovoltaic carport affecting photoelectric conversion efficiency, this application provides an eco-friendly photovoltaic self-cleaning water storage carport.

[0006] The ecological photovoltaic self-cleaning water storage carport provided in this application adopts the following technical solution:

[0007] An eco-friendly photovoltaic self-cleaning water-storing carport includes a carport roof panel, carport columns, and solar photovoltaic panels. The carport roof panel is V-shaped, with higher sides and a lower middle section. The carport roof panel is equipped with:

[0008] A drainage ditch is provided at both ends of the roof panel of the carport, and its upper end surface is not higher than the solar photovoltaic panel.

[0009] A drainage trough is provided at the lowest point of the upper surface of the roof panel of the carport; and

[0010] The rainwater inlet is connected to both the drainage ditch and the drainage channel on the same side;

[0011] The carport pillars are equipped with:

[0012] A concealed rainwater pipe is installed inside the carport pillar and connected to the rainwater inlet;

[0013] The above-ground water tank is connected to the concealed rainwater pipe; and

[0014] A rinsing mechanism for pumping water from the above-ground water tank to the roof of the carport and rinsing the solar photovoltaic panels.

[0015] Furthermore, the rinsing mechanism includes:

[0016] High-pressure nozzles are provided, with multiple nozzles arranged at the highest points on both sides of the roof panel of the carport, and their spray direction is directed towards the solar photovoltaic panel;

[0017] The water supply pipe has one end connected to multiple high-pressure nozzles and the other end connected to the above-ground water tank; and

[0018] A water pump, installed on the water supply pipe, is used to transport water stored in the ground water tank to the high-pressure nozzle.

[0019] Furthermore, multiple high-pressure nozzles on the same side are spaced apart along the length of the drainage channel.

[0020] Furthermore, the solar photovoltaic panel is electrically connected to a battery, the battery is electrically connected to multiple charging sockets, and the water pump is electrically connected to the battery.

[0021] Furthermore, the ground water tank is positioned between two adjacent carport pillars, and multiple charging sockets are arranged on both sides of the ground water tank.

[0022] Furthermore, the above-ground water tank is also connected to an underground water tank.

[0023] Furthermore, the concealed rainwater pipe is equipped with a detachable rainwater filter device, which is located inside the carport pillar.

[0024] Furthermore, an inspection hole is provided on the outer wall of the carport column, and a filter box is embedded in the inspection hole. The filter box is connected to the concealed rainwater pipe at the top and bottom. Multiple filter boxes with open tops are sealed and inserted in the filter box, and the filtration effect of the multiple filter boxes gradually increases from top to bottom.

[0025] Furthermore, the filter box is inclined, and the end of the filter box near the outer side of the carport column is higher than the end near the inner side of the carport column;

[0026] When the filter box is fully embedded in the filter chamber, the outer peripheral wall of the filter box extending into the filter chamber fits against the corresponding inner peripheral wall of the filter chamber.

[0027] Furthermore, the carport pillars are detachably equipped with sealing plates for closing the inspection holes.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The garage utilizes solar photovoltaic panels on the roof and drainage ditches and channels on the garage pillars, along with concealed rainwater pipes, to recycle rainwater. The solar photovoltaic panels on the roof generate electricity, which is stored in batteries for use in the garage's nighttime lighting and for charging electric vehicles, achieving energy self-sufficiency.

[0030] 2. Rainwater is collected through the top drainage channel, filtered by a detachable rainwater filter, and stored in above-ground and underground water tanks. The water in the tanks can be used for irrigation, and when the solar photovoltaic panels need cleaning, the water in the above-ground tanks can be pumped to the high-pressure nozzles at the top. The water from the high-pressure nozzles cleans the solar photovoltaic panels on the roof of the carport, achieving a self-cleaning effect and ensuring the conversion efficiency of the solar photovoltaic panels.

[0031] 3. By combining three main functions—a photovoltaic carport, water storage within the carport, and self-cleaning of the solar photovoltaic panels—the system utilizes electricity generated by the solar photovoltaic panels to power a water pump that pumps water collected in a tank. This water is then used to clean the photovoltaic panels via high-pressure spray nozzles. The entire system achieves complete self-cleaning, improving the conversion efficiency of the solar photovoltaic panels. It requires minimal manual intervention and fulfills multiple functions within a single carport, maximizing resource utilization. Furthermore, its battery and the removable rainwater filtration system feature detachable filter boxes, facilitating future installation and maintenance. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0045] Reference Figure 1 and Figure 2 This application discloses an ecological photovoltaic self-cleaning water storage carport, which includes a carport roof 11, carport columns 12 and solar photovoltaic panels 21. The carport roof 11 is in the shape of a "V" with high sides and low middle. At least two carport columns 12 are provided and fixed to the lower end face of the lowest part of the carport roof 11 and are spaced apart along the length of the carport roof 11. The solar photovoltaic panels 21 are laid flat on the upper surface of the carport roof 11.

[0046] The roof panel 11 of the carport is equipped with:

[0047] Drainage ditch 31 is located at both ends of the carport roof 11 and is set along the width of one side of the carport roof 11, and its upper end surface is not higher than the solar photovoltaic panel 21.

[0048] Drainage channel 32 is located at the lowest point of the upper surface of the carport roof panel 11 and is provided along the length of the carport roof panel 11; and

[0049] The rainwater inlet 33 is connected to both the drainage ditch 31 and the drainage channel 32 on the same side.

[0050] The following are provided on the carport pillar 12:

[0051] The concealed rainwater pipe 4 is installed inside the carport column 12 and connected to the rainwater inlet 33;

[0052] Above-ground water tank 51 is connected to concealed rainwater pipe 4; and

[0053] A rinsing mechanism for pumping water stored in the ground water tank 51 to the roof panel 11 of the carport and rinsing the solar photovoltaic panels 21.

[0054] Specifically, the rinsing mechanism includes:

[0055] High-pressure nozzles 61 are provided in multiple locations at the highest points on both sides of the train canopy roof 11, and their spray direction is directed toward the solar photovoltaic panel 21.

[0056] Water supply pipe 62, one end of which is connected to multiple high-pressure nozzles 61, and the other end of which is connected to a ground water tank 51; and

[0057] A water pump 63 is installed on the water supply pipe 62 and is used to transport the water stored in the ground water tank 51 to the high-pressure nozzle 61.

[0058] Thus, the solar photovoltaic panels 21 placed on the roof of the carport 11 can convert solar energy into electrical energy. Simultaneously, they can guide rainwater into drainage ditches 31 and troughs 32, and collect it through rainwater inlets 33, flowing from the concealed rainwater pipes 4 into the ground-level water tank 51, thus achieving rainwater collection. When the solar photovoltaic panels 21 need cleaning, water stored in the ground-level water tank 51 can be pumped by the water pump 63 to the water supply pipe 62, and then sprayed onto the solar photovoltaic panels 21 through multiple high-pressure nozzles 61, effectively cleaning the solar photovoltaic panels 21 and ensuring their conversion efficiency.

[0059] And in the specific configuration, refer to Figure 1 and Figure 2 Multiple high-pressure nozzles 61 on the same side are spaced apart along the length of the drainage ditch 32. A solar photovoltaic panel 21 is electrically connected to a battery 22, which in turn is electrically connected to multiple charging sockets 23. A water pump 63 is electrically connected to the battery 22. An above-ground water tank 51 is located between two adjacent carport pillars 12. Multiple charging sockets 23 are arranged on both sides of the above-ground water tank 51. The above-ground water tank 51 is also connected to a buried water tank 52.

[0060] In this way, the solar photovoltaic panels 21 on the roof of the carport 11 convert solar energy into electrical energy, which is then stored in the battery 22. This energy can be used for nighttime lighting in the garage and charging of electric vehicles, achieving energy self-sufficiency. Simultaneously, it can also supply power to the water pump 63 to pump water stored in the above-ground water tank 51 to the high-pressure sprinkler head 61 at the top. Furthermore, the underground water tank 52 further increases the water storage capacity, allowing the water stored in both the above-ground and underground tanks to be used not only for washing the solar photovoltaic panels 21 but also for irrigation, greatly improving water resource utilization.

[0061] In addition, to improve the cleanliness of the water entering the above-ground water tank 51, refer to Figure 2 and Figure 3 A detachable rainwater filter device is installed on the concealed rainwater pipe 4, and the detachable rainwater filter device is located inside the carport column 12; an inspection hole 121 is opened on the outer wall of the carport column 12, and a filter box 71 is embedded in the inspection hole 121. A sealing plate 122 for sealing the inspection hole 121 is detachably installed on the carport column 12.

[0062] The filter box 71 is connected to the concealed rainwater pipe 4 at the top and bottom. Multiple filter boxes 72 with openings at the top are sealed and inserted in the filter box 71. The filtration effect of the multiple filter boxes 72 gradually increases from top to bottom. Specifically, multiple insertion ports are opened through the side wall of the filter box 71 near the inspection hole 121. The filter boxes 72 are sealed and inserted into the insertion ports by rubber sealing rings. The filter boxes 72 are equipped with filter screens, filter cloths, filter cotton, activated carbon and other filter elements. By setting different filter elements, the filtration effect of the multiple filter boxes 72 is differentiated.

[0063] In order to extend the maintenance interval of the detachable rainwater filter, the filter box 72 is set at an angle, and the end of the filter box 72 near the outside of the carport column 12 is higher than the end near the inside of the carport column 12; when the filter box 72 is fully embedded in the filter box 71, the outer peripheral wall of the filter box 72 extending into the filter box 71 is in contact with the corresponding inner peripheral wall of the filter box 71.

[0064] In this way, when the rainwater collected by the rainwater inlet 33 flows through the concealed rainwater pipe 4, it needs to pass through the filter box 71 before entering the ground water tank 51. When the rainwater passes through the filter box 71, it passes through multiple filter boxes 72 arranged from top to bottom in sequence. Different filter elements in the multiple filter boxes 72 filter the rainwater to different degrees in sequence. For example, the filter screen first filters out larger impurities, the filter cloth filters out smaller impurities such as dust, and then the filter cotton or activated carbon adsorbs harmful substances in the rainwater. This can ensure the cleanliness of the rainwater entering the ground water tank 51.

[0065] After a period of operation, the sealing plate 122 can be removed first, and then the corresponding filter box 72 can be pulled out of the filter housing 71. The filter elements in the filter box 72 can then be cleaned or replaced to maintain its effectiveness in filtering rainwater. The tilted design of the filter box 72 helps impurities in the rainwater accumulate at the lower end, ensuring that the higher end of the filter box 72 maintains a certain filtration capacity and rainwater passage capacity. This extends the effective filtration time of the filter box 72, reducing the need for frequent maintenance.

[0066] The implementation principle of the ecological photovoltaic self-cleaning water storage carport in this application embodiment is as follows:

[0067] The solar photovoltaic panels 21, mounted on the roof of the carport 11, convert solar energy into electrical energy. They also guide rainwater into drainage ditches 31 and troughs 32, where it is collected by rainwater inlets 33 and flows through concealed rainwater pipes 4 into a ground-level water tank 51, thus collecting rainwater. When the solar photovoltaic panels 21 need cleaning, a water pump 63 draws water from the ground-level water tank 51 into a water supply pipe 62, which is then sprayed onto the solar photovoltaic panels 21 through multiple high-pressure nozzles 61, effectively cleaning the panels and ensuring their conversion efficiency.

[0068] Furthermore, the solar photovoltaic panels 21 on the roof of the carport 11 convert solar energy into electrical energy, which is then stored in the battery 22. This energy can be used for nighttime lighting in the garage and charging of electric vehicles, achieving energy self-sufficiency. Simultaneously, it can also supply power to the water pump 63 to pump water stored in the above-ground water tank 51 to the high-pressure sprinkler head 61 at the top. The underground water tank 52 further increases the water storage capacity, allowing the water stored in both the above-ground and underground tanks to be used not only for washing the solar photovoltaic panels 21 but also for irrigation, greatly improving water resource utilization.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
