Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to photovoltaic water collection systems. Background Technology

[0002] Centralized photovoltaic (PV) power plants, as an important method of renewable energy generation, have been widely used globally. In my country, most centralized PV power plants are located in arid and semi-arid regions with abundant sunshine. These areas suffer from water scarcity and fragile ecosystems. To ensure the efficient operation of PV power plants while reducing operating and maintenance costs and protecting the ecological environment, how to efficiently utilize limited water resources in PV power plants has become a critical issue that urgently needs to be addressed.

[0003] During operation, photovoltaic (PV) power plants are susceptible to contamination from dust and sand on the surface of their modules, affecting power generation efficiency. Therefore, regular cleaning of the PV panels is essential. However, in arid regions where water resources are scarce, traditional manual cleaning methods require large amounts of water, leading to high operating costs and further exacerbating local water resource pressures. Therefore, developing efficient and water-saving cleaning and water resource management methods is crucial for improving the sustainable development of centralized PV power plants.

[0004] Current photovoltaic (PV) power plant water collection and utilization schemes typically involve installing water collection troughs or pipes along the lower edge of each row of PV modules. These devices collect natural rainfall and transport it to a storage system for reuse during PV module cleaning. This method of water collection and storage achieves water resource reuse, reducing water consumption and alleviating water resource pressure to some extent. However, existing water collection structures are mostly additional components, increasing installation costs and potentially impacting the layout and structure of the PV power plant during installation and maintenance.

[0005] Therefore, optimizing the water collection system design of photovoltaic power plants and improving water resource collection and utilization efficiency without significantly increasing costs has become an important research direction in the current technological field. At the same time, optimizing the water collection system structure, reducing maintenance difficulty, and improving equipment durability will further promote the green and energy-saving development of photovoltaic power plants.

When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0050] In this utility model, the terms "a", "an", "the", "the", and "at least one" are used to indicate the existence of one or more elements / components / etc.; the terms "comprising", "including", and "having" are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0051] According to one aspect of the present invention, a photovoltaic water collection system is provided, with reference to... Figures 1 to 4 As shown, the photovoltaic water collection system includes:

[0052] A photovoltaic module includes a plurality of photovoltaic panels 1 arranged in a continuous manner;

[0053] Support device 2, with its bottom buried underground and its top connected to and supporting the photovoltaic panel 1;

[0054] A water storage device 3 is used to receive water flowing out of the photovoltaic panel 1. The water storage device 3 is located below the photovoltaic panel 1 and is mounted on the support device 2.

[0055] In this invention, the photovoltaic panel 1 can generate electricity using solar energy. The design of the support device 2 not only stably supports the photovoltaic panel 1 but also supports the water storage device 3 located on it, thereby increasing the stability and durability of the system. Furthermore, burying the support device 2 underground enhances its wind and earthquake resistance, especially in relatively arid plateau regions.

[0056] By setting up a water storage device 3, the system can effectively collect and store rainwater or residual water from cleaning photovoltaic panels 1, providing water for agricultural irrigation, cleaning or other purposes, thus achieving the effect of water conservation.

[0057] This invention does not limit the specific structure of the support device 2. In some embodiments, the support device 2 may include various structural forms. For example, the support device 2 may be a fixed bracket, a movable bracket, or an adjustable bracket to adapt to different usage scenarios and needs. In addition, the support device 2 may also include shock-absorbing components, a rotating mechanism, or a height adjustment mechanism to further enhance the stability and flexibility of the equipment. These designs can be selected and combined according to actual application conditions to achieve the best support effect.

[0058] In some exemplary embodiments of this utility model, the support device 2 includes:

[0059] Multiple purlins 21 are evenly spaced;

[0060] Inclined beams 22 are disposed below the purlins 21 and are connected to each of the purlins 21 respectively, for supporting the purlins 21;

[0061] The column 23 is set on the center line of the inclined beam 22, with one end buried in the ground, to provide vertical support for the support device 2;

[0062] The diagonal brace 24 has one end located at the end of the column 23 away from the ground and the other end connected to the inclined beam 22. Its length extension direction intersects the length extension direction of the column 23 and the length extension direction of the inclined beam 22, respectively.

[0063] In this way, with one end of the column 23 buried underground along the entire support direction, it can provide a solid support foundation for the entire support device 2, thereby effectively bearing the weight from the photovoltaic panel 1 and the water storage device 3, and reducing the risk of tilting and instability of the system caused by ground subsidence or soil loosening.

[0064] The design of the diagonal brace 24 enables the support device 2 to have a higher resistance to deformation when subjected to lateral external forces (such as wind and seismic forces). The extension direction of the diagonal brace 24 intersects with the column 23 and the diagonal beam 22, forming a triangular support structure, which optimizes the stress distribution, helps to disperse and offset external stress, and enhances the system's wind and earthquake resistance.

[0065] The evenly spaced purlins 21 are supported by inclined beams 22. With the cooperation of columns 23 and diagonal braces 24, the overall support device 2 forms a stable frame structure with good anti-overturning and anti-seismic effects, and can stably support the photovoltaic panel 1 and the water storage device 3 for a long time.

[0066] To further enhance the stability and resistance to external forces of the photovoltaic water collection system structure, in some exemplary embodiments of this utility model, two diagonal braces 24 may be designed, and the two diagonal braces 24 are arranged symmetrically about the column 23.

[0067] In this way, on the one hand, the two diagonal braces 24 are arranged symmetrically about the column 23, which makes the support device 2 more symmetrical in structure, thus more evenly distributing and bearing the weight from the photovoltaic panel 1 and the water storage device 3. This avoids stress concentration, reduces local structural losses, effectively improves system stability, reduces the risk of tilting or swaying caused by uneven stress, and thus extends the service life of the system. On the other hand, the symmetrical double diagonal brace structure 24 can better disperse and offset the effects of external forces when encountering lateral forces such as lateral wind or earthquakes, reducing structural deformation and displacement caused by external disturbances, and giving the system superior performance in wind and earthquake resistance.

[0068] Furthermore, in this embodiment of the invention, the installation height difference between adjacent purlins 21 can be provided. Since the photovoltaic panel 1 is sheet-like, adjacent photovoltaic panels 1 are connected by purlins 21. Because of the height difference between adjacent purlins 21, the photovoltaic panel 1 will inevitably be placed at an angle, causing water on the photovoltaic panel 1 to flow obliquely into the purlins 21, thus facilitating water collection in the purlins 21.

[0069] Since the photovoltaic panel 1 is installed at an angle, the water flowing out of it may fall directly onto the ground along its slope rather than into the water storage device 3. In some embodiments, a diversion device can be installed between the photovoltaic panel 1 and the water storage device 3 to guide the water from the photovoltaic panel 1 into the water storage device 3. The diversion device can be a diversion pipe, a diversion trough, etc., to facilitate the guidance and collection of water and prevent water loss.

[0070] In some exemplary embodiments of this utility model, based on the aforementioned scheme, each purlin 21 is provided with a first drainage hole 211, the first drainage hole 211 being aligned with the groove of the inclined beam 22, so that water in the purlin 21 can enter the groove of the inclined beam 22 through the first drainage hole 211.

[0071] In this way, the first drainage hole 211 allows rainwater on the purlin 21 to directly enter the groove of the inclined beam 22. This not only effectively reduces water overflow and accumulation in the purlin 21, but also prevents water from accumulating on the purlin 21 for extended periods, thus reducing the pressure requirements on the purlin 21 and extending its service life. Furthermore, this invention fully utilizes the installation position between the purlin 21 and the inclined beam 22 to guide water flow without requiring additional drainage devices, simplifying the structural design and reducing the system's manufacturing and installation costs.

[0072] This invention does not limit the specific structure of the purlin 21. In some embodiments, the purlin 21 can be configured in various structural forms to adapt to different installation and usage requirements. For example, the purlin 21 can adopt a channel-shaped, I-shaped, or square cross-section structure, or be configured with a certain inclination angle to better guide water flow. In addition, the material and size of the purlin 21 can be selected according to actual conditions to meet the requirements of strength, corrosion resistance, and durability, thereby ensuring the stability and service life of the structure.

[0073] Considering both structural stability and water storage function, in some exemplary embodiments of this utility model, reference is made to... Figure 2 As shown, the purlin 21 includes:

[0074] The first connecting part 212 is located on one side of the purlin 21 and is used to connect one side of the photovoltaic panel 1;

[0075] The second connecting part 213 is located on the other side of the purlin 21 and is used to connect one side of the adjacent photovoltaic panel 1;

[0076] The first water storage section 214 is located between the first connecting section 212 and the second connecting section 213, and is used to receive and collect water flowing down from the photovoltaic panel 1.

[0077] The first connecting portion 212 and the second connecting portion 213 are both recessed into the inner side of the purlin 21 to form a groove in the first water storage portion 214; the first drainage hole 211 is located inside the first water storage portion 214.

[0078] Thus, the first connecting part 212 and the second connecting part 213 are located on both sides of the purlin 21, which not only fixes the adjacent photovoltaic panels 1, but also provides reliable support. The recessed design allows the connecting parts to bear a certain water storage function without increasing the thickness of the purlin 21 or affecting its load-bearing capacity, maintaining the stability and durability of the structure. The integration of the connecting parts and water storage parts on the purlin 21 makes the design more compact, saving space and maintaining a neat and beautiful appearance. At the same time, the recessed water storage groove design can hide water flow marks and maintain the overall clean appearance. Moreover, the fact that all connecting parts and water storage parts are designed on the purlin 21 makes installation easier, thereby reducing additional connectors and pipes and lowering installation and material costs. During maintenance, the grooved structure is easy to clean and helps to avoid blockages or dirt accumulation caused by water accumulation.

[0079] This invention does not limit the structure of the inclined beam 22. For example, in some embodiments, considering the drainage function of the inclined beam 22, the inclined beam 22 can be configured to be similar in structure to the purlin 21. Based on this, refer to Figure 2 As shown, the inclined beam 22 includes:

[0080] The third connecting part 222 is located on one side of the inclined beam 22;

[0081] The fourth connecting part 223 is located on the other side of the inclined beam 22 and is connected to the purlin 21 at the same time as the third connecting part 222;

[0082] The second water storage section 224 is located between the third connecting section 222 and the fourth connecting section 223, and is used to receive and collect water flowing down from the first water storage section 214;

[0083] The first drainage hole 211 is positioned to align with the second water storage section 224, so that water in the first water storage section 214 of the purlin 21 can enter the second water storage section 224 of the inclined beam 22.

[0084] By aligning the first drainage hole 211 directly with the second water storage section 224, water in the purlin 21 can be ensured to enter the water storage area (second water storage section 224) of the inclined beam 22, thus preventing water loss during conduction. Furthermore, the first water storage section 214 and the second water storage section 224 form a multi-stage water storage structure, enabling the system to collect and store rainwater efficiently, thus achieving efficient water collection and management. The third connecting section 222 and the fourth connecting section 223 are respectively located on both sides of the inclined beam 22, doubly fixing the inclined beam 22 and the purlin 21, thereby improving the system's wind and earthquake resistance.

[0085] In some exemplary embodiments of this utility model, reference is made to Figure 2 As shown, the diagonal brace 24 can be designed to include:

[0086] The first open end 241 is formed as one end connected to the column 23;

[0087] The second open end 242 is formed as one end connected to the inclined beam 22;

[0088] One end of the inclined beam 22 is positioned near and abuts against the second opening end 242, so that water in the inclined beam 22 can enter the inclined support 24; and a water storage hole 31 is provided on the top of the water storage device 3, with the first opening end 241 aligned with the water storage hole 31, so that water in the inclined support 24 can enter the water storage device 3 through the water storage hole 31.

[0089] The second open end 242 of the diagonal brace 24 is in close contact with the diagonal beam 22, allowing water in the diagonal beam 22 to flow smoothly into the diagonal brace 24, thus realizing a seamless water flow transmission path from the diagonal beam 22 to the diagonal brace 24.

[0090] Of course, in other implementations, refer to Figure 3 As shown, the inclined beam 22 can also be designed with water holes, which are aligned with the second opening end 242 of the inclined brace 24, so that water in the inclined beam 22 can enter the inclined brace 24 through the water holes.

[0091] The design of the water flow holes provides flexible water flow channel options to adapt to the needs of different projects and installation environments. Users can flexibly choose to open or close the water flow holes during installation according to the actual situation, which enhances the adaptability of the system. On the other hand, it makes the water flow path shorter and more concentrated, which facilitates daily inspection and cleaning.

[0092] To facilitate water outflow from the inclined beam 22, in some embodiments, a drainage pipe can be incorporated into both the inclined beam 22 and the water storage device 3. However, to save design space while improving system stability, a second drainage hole is also provided on the inclined beam 22 in some exemplary embodiments of this utility model; the support device 2 further includes a straight brace 25, which comprises:

[0093] The third opening end 251 is connected to the inclined beam 22 and aligned with the second drainage hole, so that water in the inclined beam 22 can enter the straight support 25 through the second drainage hole;

[0094] The fourth opening end 252 is connected to the column 23 and aligned with the water storage hole 31, so that water in the straight support 25 can enter the water storage device 3 through the water storage hole 31.

[0095] By implementing water conduction within the diagonal brace 24, additional external drainage pipes and components can be avoided, saving system space. Simultaneously, the diagonal brace 24 serves as a water flow channel while providing structural support, thereby simplifying the design and reducing material consumption and installation complexity.

[0096] The open end of the diagonal brace 24 is aligned with the drainage hole and the water storage hole 31, making the water flow conduction path clear and closed, thereby effectively reducing the risk of water leakage and seepage, and further improving the waterproof performance of the system, especially in long-term use and rainy environments.

[0097] In addition, the diagonal brace 24 provides support while also serving as a water diversion function, rationally distributing the weight of the water flow and the structural load, thus avoiding overload of a single component and extending the life of the support device 2.

[0098] Since the entire photovoltaic module is composed of multiple continuously arranged photovoltaic panels 1, its overall length and width are relatively large. The spacing of multiple purlins 21 can meet the support requirements of the photovoltaic module in one direction. To ensure continuous and stable support in the other direction, in some exemplary embodiments of this utility model, multiple support devices 2 are used, and these support devices 2 are evenly spaced to better distribute the load.

[0099] The multiple support devices 2 are evenly distributed at intervals, which not only makes the overall load-bearing of the system more uniform, reduces stress concentration in local structures, and reduces the risk of tilting and deformation, thus effectively distributing the weight of photovoltaic modules and water storage devices 3; but also disperses stress under external forces such as wind or earthquakes, thereby effectively resisting horizontal and vertical impacts, and further providing stronger wind and earthquake resistance.

[0100] Most existing photovoltaic panels are installed vertically and lack water collection capabilities. However, with increasing demands for environmental protection and resource utilization, integrating rainwater harvesting into photovoltaic systems is becoming increasingly important. On one hand, a well-designed water collection system can effectively collect natural rainfall for irrigation, cleaning, and other purposes, thus conserving water resources. On the other hand, by changing the installation method of the photovoltaic panels, the stability of the system can be improved, and the collection and discharge paths of rainwater can be optimized.

[0101] In this invention, by arranging the photovoltaic panels 1 horizontally, their surface area can be better utilized to guide rainwater, making it easier for water to flow to the purlins 21 and the water storage device 3, thereby improving the system's water collection efficiency. Moreover, the horizontally arranged photovoltaic panels 1 can not only optimize the angle of sunlight reception to a certain extent and improve the overall power generation efficiency, but also better disperse wind force, making the wind's influence more evenly distributed, reducing the concentrated effect of local wind loads, and helping to improve the system's wind resistance stability.

[0102] This invention is particularly suitable for arid regions with scarce water resources.
