Description

Technical Field

[0001] This utility model relates to the field of solar greenhouse technology, and in particular to photovoltaic solar greenhouses. Background Technology

[0002] Existing distributed photovoltaic (PV) businesses primarily focus on PV canopies and building-integrated photovoltaics (BIPV) applications. Waterproofing is a crucial and challenging aspect of PV module installation. Current PV canopies typically employ a four-tiered waterproofing structure to form a drainage system, based on drainage from the connected PV modules and waterproofing along the roof edges. The fourth tier involves installing water channel brackets welded to the north and south slope beams to create installation positions for the water channels. This installation method not only increases the types of materials and construction procedures but also affects the overall appearance, thus limiting its application scenarios. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a photovoltaic solar greenhouse, comprising:

[0005] The ceiling structure includes multiple horizontal beams and multiple vertical beams, which are spliced ​​together such that the upper surfaces of at least some of the horizontal beams and at least some of the vertical beams are flush to form at least one supporting plane, which is inclined in the vertical direction.

[0006] A photovoltaic structure includes a plurality of photovoltaic panels laid on the supporting plane, with the sidewalls of two adjacent photovoltaic panels abutting; and,

[0007] A drainage structure includes at least one trough located on the side of the ceiling structure. One edge of the trough is fixed to the crossbeam or the longitudinal beam. The trough has an upwardly open drainage channel that connects to the lower end of the supporting plane.

[0008] In one embodiment, there are two supporting planes, which are gradually inclined downwards in a direction away from each other. The two supporting planes are connected on one side, and the groove is provided on the other side facing away from each other.

[0009] In one embodiment, the tank includes:

[0010] The body has an upward-facing drainage channel that extends through it along its length; and

[0011] A connecting part is provided on one side of the main body and connected to the upper edge of the main body. The connecting part overlaps and is fixed to the end of the corresponding crossbeam or longitudinal beam.

[0012] In one embodiment, the width of the drainage channel gradually increases from bottom to top.

[0013] In one embodiment, the sidewall of the drainage channel away from the connection portion is stepped in the vertical direction.

[0014] In one embodiment, the sidewall of the drainage channel away from the connection portion is formed with a plurality of steps arranged sequentially in the vertical direction, each step being arc-shaped and / or two adjacent steps having an arc transition.

[0015] In one embodiment, the sidewall of the drainage channel away from the connection is bent upward and toward the center of the drainage channel to form a bend.

[0016] In one embodiment, the connecting part is fixed to the corresponding crossbeam or longitudinal beam by a plurality of fasteners, and the gap between the connecting part and the corresponding crossbeam or longitudinal beam is filled with sealant.

[0017] In one embodiment, the drainage structure further includes two end caps, which are adapted to the cross-sectional profile of the trough and are installed on opposite sides of the main body to seal the drainage trough.

[0018] In one embodiment, multiple troughs are provided, the multiple troughs are spliced ​​together and the multiple drainage troughs are interconnected, and the multiple troughs are used to surround the periphery of the ceiling structure.

[0019] In one embodiment, two adjacent grooves are connected by an adapter, the adapter having an upward-opening adapter groove having two groove segments arranged at an angle;

[0020] The ends of the two corresponding troughs extend into the two trough segments to connect the drainage channels of the two corresponding troughs through the transition groove.

[0021] In one embodiment, the length of the overlapping portion of the groove body and the corresponding groove segment ranges from 250 mm to 300 mm.

[0022] In one embodiment, multiple adapters are provided, including a first adapter, wherein the two slots of the first adapter are arranged at an angle in the horizontal plane.

[0023] In one embodiment, multiple adapters are provided, including a second adapter, wherein the ends of the two slots of the second adapter that are away from each other are inclined downwards.

[0024] In one embodiment, the upper side of the overlapping portion of the connecting part and the adapter is fixed together by a plurality of fasteners, and the overlapping portion of the connecting part and the adapter is filled with sealant.

[0048] Please refer to Figures 1 to 3In existing photovoltaic (PV) canopy structures, the roof structure 1' has two opposing first sides and two opposing second sides. The longitudinal beam 12' serves as the foundation of the roof structure 1', and the transverse beam 11' (purlin) overlaps above the longitudinal beam 12' (diagonal beam), creating a height difference between them. The lower end face of the transverse beam 11' is flush with the upper end face of the longitudinal beam 12', serving as support for the photovoltaic structure 2'. The photovoltaic structure 2' is laid on a plane composed of multiple transverse beams 11'. Due to this structural form, there is a seam between adjacent photovoltaic panels, and this seam is suspended, making it difficult to seal. Given that the seam leaks during rain, when setting up the drainage structure 3', a drainage system is first installed below the seam of the photovoltaic panels on the first side. A first-stage water trough 31' overlaps with the crossbeam 11'. Considering that the first-stage water trough 31' is spliced ​​from multiple substrates, and the gap between the two substrates also presents a suspension problem, a second-stage water trough 32' is set below the joint of the first-stage water trough 31'. The second-stage water trough 32' overlaps with the longitudinal beam 12' and is flush with the crossbeam 11'. Similarly, a third-stage water trough 33' is set below the longitudinal beam 12'. A fourth-stage water trough 34' is set at the inclined end of the entire ceiling structure 1', ensuring that the water in the first-stage water trough 31' and the third-stage water trough 33' can be diverted into the fourth-stage water trough 34', thus forming a four-stage drainage system.

[0049] Please refer to Figure 2 The fourth-stage water tank 34' is supported and installed via an L-shaped water tank bracket 35'. Please refer to... Figure 3 Some users raised aesthetic requirements, so it is necessary to seal the two second sides of the ceiling structure 1'. Considering that in the overall structure, the water trough bracket 35' on the first side is fixedly installed based on the longitudinal beam 12', and the water trough bracket 35' on the second side can only be fixedly installed based on the transverse beam 11' if it is to be installed, there is a height difference between the transverse beam 11' and the longitudinal beam 12'. Therefore, if water troughs are installed on both the first and second sides, there will be a height difference between the water troughs on the two sides, which will cause difficulties in the connection. Therefore, the existing sealing structure 36' is only for decoration and does not have a drainage function.

[0050] In view of this, the present invention provides a photovoltaic sunshade that abandons the existing four-stage drainage system and only requires a single-stage drainage system to meet the drainage function, thereby reducing construction costs and expanding the scope of application scenarios.

[0051] Please refer to Figures 4 to 5The photovoltaic solar greenhouse 100 includes a roof structure 1, a photovoltaic structure, and a drainage structure 3. The roof structure 1 includes multiple horizontal beams 11 and multiple vertical beams 12. The multiple horizontal beams 11 and multiple vertical beams 12 are spliced ​​together so that the upper surfaces of at least some of the horizontal beams 11 and at least some of the vertical beams 12 are flush to form at least one supporting plane 1a. The supporting plane 1a is inclined in the vertical direction. The photovoltaic structure includes multiple photovoltaic panels laid on the supporting plane 1a, and the side walls of two adjacent photovoltaic panels are attached together. The drainage structure 3 includes at least one trough 31. The trough 31 is located on the side of the roof structure 1. One edge of the trough 31 is fixed to the horizontal beam 11 or the vertical beam 12. The trough 31 has an upward-opening drainage channel, which is connected to the lower end of the supporting plane 1a.

[0052] In this invention, the upper surfaces of the horizontal beams 11 and the longitudinal beams 12 are aligned, ensuring that the spliced ​​roof has at least one supporting plane 1a. During photovoltaic panel installation, adjacent photovoltaic panels can be supported by both the horizontal beams 11 and the longitudinal beams 12, with the joints falling on either the horizontal beams 11 or the longitudinal beams 12, achieving a seamless fit. This results in a complete flat photovoltaic structure, with only the lower side of the roof structure 1 connected to the channel 31, thus meeting the drainage requirements of the entire photovoltaic structure. Compared to the traditional four-stage drainage system of photovoltaic sunshades, this invention eliminates the multi-stage overlapping structure of the drainage channels, simplifying the drainage system, reducing the types of materials used, and lowering costs.

[0053] It should be noted that the overlapping method of the crossbeams 11 and longitudinal beams 12 is not limited. For example, multiple longitudinal beams 12 can be laid flat, each longitudinal beam 12 can be inclined, and each crossbeam 11 can be formed by multiple base material segments. Each base material segment is embedded between two adjacent longitudinal beams 12, thereby achieving that the upper surfaces of the crossbeams 11 and longitudinal beams 12 are flush. Alternatively, by appropriately selecting the material of the crossbeams 11, local deformation of the crossbeams 11 can be made to form a recess, allowing them to snap onto the outside of the longitudinal beams 12, making the remaining part of the crossbeams 11 flush with the longitudinal beams 12. The overlapping part is a thin layer superimposed on the surface of the longitudinal beams 12, thus minimizing the impact on the splicing of the photovoltaic panels. Another example is that the crossbeams 11 and longitudinal beams 12 can be cross-interlocked, ultimately achieving that the upper surfaces of the crossbeams 11 and longitudinal beams 12 are flush.

[0054] It should be understood that, based on the flush arrangement of the crossbeams 11 and 12, when multiple photovoltaic panels are laid, the crossbeams 11 and 12 simultaneously serve to support the photovoltaic panels. By placing the joints of adjacent photovoltaic panels on the crossbeams 11 or 12, seamless bonding can be achieved by filling with adhesive.

[0055] The spacing between multiple crossbeams 11 can be the same or different, and the distance between multiple longitudinal beams 12 can be the same or different. This utility model does not impose any restrictions on this.

[0056] The canopy structure 1 can be a single supporting plane 1a, in which case the canopy is shaped like a "\". Water flow is guided along the inclined direction of the supporting plane 1a, so a trough 31 can be provided only at the tail end of the supporting plane 1a. In some embodiments, please refer to... Figure 5 There are two supporting planes 1a. The two supporting planes 1a are connected on one side and gradually slope downwards on the other side away from each other. At this time, the ceiling is in the shape of "︿". Considering the drainage situation, a trough 31 is provided on the other side of the two supporting planes 1a facing away from each other.

[0057] It should be noted that the drainage channel of the trough 31 can be continuous or blocked at both ends.

[0058] In one embodiment, please refer to Figures 6 to 8 The trough 31 includes a body 311 and a connecting part 312. The body 311 forms a drainage trough with its opening facing upward and extending through its length. The connecting part 312 is located on one side of the body 311 and connected to the upper edge of the body 311. The connecting part 312 overlaps and is fixed to the end of the corresponding horizontal beam 11 or vertical beam 12. In this structure, the drainage trough is a structure with both ends extending through it, allowing water to flow out from both ends of the drainage trough after being collected. Because the horizontal beam 11 and the vertical beam 12 are flush, the installation of the trough 31 is no longer limited by the requirements of multi-stage drainage collection and installation height. According to the horizontal and vertical orientation of the connecting part 312, the connecting part 312 can be directly fixed to the horizontal beam 11 or the vertical beam 12. Compared with the traditional solution, there is no need to weld a water tank bracket, reducing the types of materials and construction procedures, and realizing photovoltaic building integration to a greater extent.

[0059] The connecting part 312 is integrally formed with the body 311, that is, a flange can be processed on the corresponding side of the body 311 to form the connecting part 312. The length of the connecting part 312 can be the same as the length of the body 311, and the connecting part 312 can also be composed of multiple narrow flanges arranged at intervals.

[0060] Regarding the connection between the groove 31 and the roof structure 1, in this embodiment, the connecting part 312 is fixed to the corresponding crossbeam 11 or longitudinal beam 12 as a whole by multiple fasteners, and the gap between the connecting part 312 and the corresponding crossbeam 11 or longitudinal beam 12 is filled with sealant. That is, the combination of fasteners and sealant achieves a double-fastening purpose. Considering the tightness of the connection, self-tapping screws of ST5.5X25 or larger can be selected as fasteners, and weather-resistant sealant can be used.

[0061] However, it should be understood that at least three fasteners should be provided at each connection point. For example, when the groove 31 is fitted with the longitudinal beam 12, the corresponding part of the groove 31 is locked to one of the longitudinal beams 12 by three fasteners.

[0062] Furthermore, the width of the drainage channel gradually increases from bottom to top. That is, the opening size of the drainage channel is varied, which can better catch the water flowing down from the surface of the photovoltaic structure.

[0063] This utility model does not limit the form of changing the size of the drainage trough, and the two opposite side walls of the drainage trough can be set to be inclined in a direction away from each other. Considering that the trough 31 is directly connected to the crossbeam 11 or the longitudinal beam 12, the side of the trough 31 may abut against the end of the crossbeam 11 or the longitudinal beam 12. Therefore, only the side wall of the drainage trough away from the connecting part 312 can be set to be inclined in the vertical direction.

[0064] Please refer to Figure 8 The sidewall of the drainage channel away from the connection part 312 is stepped in the vertical direction. Please refer to... Figure 6 The sidewall of the drainage channel away from the connecting part 312 has multiple steps arranged sequentially in the vertical direction, each step is arc-shaped and / or two adjacent steps have an arc transition. At this time, the wall surface corresponding to the drainage channel is generally wavy, which makes the transition smoother and easier to process.

[0065] Furthermore, the sidewall of the drainage channel away from the connecting part 312 bends upward and towards the center of the drainage channel to form a bend 313. The bend 313 protrudes upward from the drainage channel, and during water collection, the bend 313 can play a certain role in blocking water. Specifically, when water flows down rapidly, it may cause splashing, and the presence of the bend 313 can effectively block these splashing water droplets. This design not only improves drainage efficiency but also reduces the impact of water splashes on the surrounding environment. As for the structural form of the bend 313, there are no strict restrictions. It can be flexibly designed as an inverted L-shape or an inverted U-shape. This design diversity allows the bend 313 to better adapt to different usage scenarios and needs, while also improving the overall structural strength of the channel body 31.

[0066] Please refer to Figure 7 and Figure 9The drainage structure 3 also includes two end caps 32, which are adapted to the cross-sectional profile of the trough 31. The two end caps 32 are installed on opposite sides of the main body 311 to seal the drainage trough. The end caps 32, through their shape adaptation, can be fastened to the ends of the main body 311 to seal the drainage trough. Water in the drainage trough is then discharged through the added downpipe 34. The end caps 32 not only significantly improve the overall aesthetics but also effectively prevent water from splashing out from the entrance side of the sunroom, thereby enhancing safety and comfort during use.

[0067] Depending on the user's different needs, it may be necessary to seal the perimeter of the ceiling structure 1. In this embodiment, multiple channels 31 can be provided, which are spliced ​​together and interconnected. These channels 31 are used to surround the perimeter of the ceiling structure 1. The drainage channels can be configured as through channels to facilitate interconnection. Please refer to... Figure 1 In this embodiment, multiple channels 31 are spliced ​​together to form an annular channel structure surrounding the perimeter of the ceiling structure 1. Specifically, the channels 31 on both sides in the lateral direction are connected and fixed to the ends of the crossbeams 11, and the channels 31 on both sides in the longitudinal direction are connected and fixed to the ends of the longitudinal beams 12. Because the crossbeams 11 and the longitudinal beams 12 are flush, there is no height difference at the joints of the channels 31 on different sides after installation, thus enabling the drainage structure 3 to drain water from the perimeter of the ceiling structure 1.

[0068] To achieve splicing between adjacent tanks 31, in some embodiments, two adjacent tanks 31 are connected by an adapter 33. The adapter 33 has an upward-facing adapter groove 331 with two groove segments arranged at an angle. The ends of the two corresponding tanks 31 extend into the two groove segments to connect the drainage channels of the two corresponding tanks 31 through the adapter groove 331. The angle between the two groove segments can adapt to the orientation of the two adjacent tanks 31, and the adapter groove 331 compensates for the distance between the two adjacent tanks 31, thereby achieving a connection.

[0069] It should be understood that, depending on the number of tanks 31, multiple adapter slots 331 should be provided.

[0070] In some implementations, please refer to Figures 10 to 11 The adapter 33 at the corner of the ceiling structure 1 is the first adapter 33a. The adapter groove 331 in the first adapter 33a includes two first groove segments arranged at an angle in the horizontal plane and an arc-shaped transition groove segment connecting the two first groove segments, thereby realizing the flow-guiding fit of the two groove bodies 31 connected in the horizontal and vertical directions. At this time, the first groove segment and the second groove segment correspond to the two groove segments for the groove body 31 to be inserted and fitted.

[0071] In some embodiments, please refer to Figures 12 to 13When the ceiling structure 1 includes two supporting planes 1a arranged at an angle, the adapter 33 corresponding to the junction of the two supporting planes 1a is a second adapter 33b. The second adapter 33b includes two second groove segments, with the ends of the two second groove segments facing downwards to accommodate the inclination of each supporting plane 1a. At this time, the two second groove segments serve as two groove segments for the insertion and fitting of the groove body 31. When drainage is installed on this side of the ceiling structure 1, each groove body 31 is placed at an inclination to correspond to the supporting plane 1a. By adapting the second adapter 33b to the two groove bodies 31 with different inclination directions, the drainage at the ridge is completed.

[0072] Based on the above embodiments, the design of the bend 313, when multiple grooves 31 are connected by the adapter, this inward-turning structure helps to enhance the overlap strength. It should be understood that, in terms of shape, the adapter 33 should at least be consistent with the body 311 and the connecting part 312. The adapter 33 may be bent corresponding to the bend 313, or it may not be bent.

[0073] To prevent leakage after the tank 31 is connected via the adapter 33, in this embodiment, the upper side of the contact area between the connecting part 312 and the adapter 33 is fixed together by multiple fasteners, and the gap between the overlapping parts of the connecting part 312 and the adapter 33 is filled with sealant. This combination of fastener securing and sealant filling ensures sealing and connection strength. During structural assembly, it is recommended to use ST5.5X25 or higher specification self-tapping screws as threaded connections to ensure a strong connection and structural stability. These self-tapping screws, due to their excellent self-drilling ability, can effectively penetrate materials and form threads, thus achieving a reliable connection. Simultaneously, to ensure the durability and moisture resistance of the connection points, it is recommended to use a weather-resistant sealant for sealing. Weather-resistant sealants have excellent UV resistance and temperature change resistance, enabling them to adapt to various harsh external environments and effectively extend the service life of the structure.

[0074] It should be noted that the fasteners should correspond to the side wall of the drainage channel and be located on the upper side of the mating area. This is because if the fasteners are installed too low, gaps may be created due to screw installation, thereby increasing the risk of leakage.

[0075] Furthermore, the overlapping length of the corresponding groove segment connected to the groove body 31 ranges from 250mm to 300mm, meaning the groove body 31 extends into the corresponding groove segment by 250mm to 300mm, thus ensuring connection strength and waterproof performance. This overlapping design within this length range ensures a stable connection between the adapter 33 and the groove body 31 while effectively preventing water penetration. Through precise calculations and experimental verification, we found that an overlap length of 250mm to 300mm ensures structural strength while minimizing material usage and reducing costs. In addition, this design also considers ease of installation, enabling construction workers to quickly complete assembly and improve work efficiency. Therefore, this overlap length setting is the optimal solution derived after considering multiple factors.

[0076] To drain water from the drainage trough to the ground, the drainage structure 3 also includes multiple downpipes 34 extending vertically. The upper ends of the downpipes 34 are used to connect to the drainage trough or the transition trough 331. Specifically, a downpipe 34 should be installed at each transition trough 331 to prevent water accumulation. Multiple downpipes 34 can be reasonably arranged horizontally or vertically according to the size of the ceiling structure 1 and the size of the drainage trough. The multiple downpipes 34 are arranged at intervals to correspond to different drainage troughs.

[0077] When discussing the structural design of the downpipe 34, it should be noted that in order to ensure the smooth guidance and discharge of water, the downpipe 34 needs to be designed with an inclined shape. This inclined design helps the water flow naturally along the inner wall of the downpipe 34, thereby effectively preventing water accumulation and blockage. Through this design, the downpipe 34 can better perform its guiding function, ensuring that rainwater or other liquids can be quickly guided from a high place to a low place, thus achieving the purpose of drainage.

[0078] In addition, the materials of the tank body 31 and the adapter 33 can be AL6063-T5 or higher grade aluminum alloy, or S350GD-ZM275 galvanized aluminum-magnesium alloy, thereby saving costs while ensuring strength requirements.

[0079] Based on the two roof structures 1 arranged at an angle on the supporting plane 1a, the following describes several different arrangements of the drainage structure 3 through several embodiments.

[0080] Example 1

[0081] Two troughs 31 are provided only on the two supporting planes 1a away from each other. The connecting parts 312 of each trough 31 are overlapped and fixed to the ends of multiple longitudinal beams 12. Each longitudinal beam 12 is fixed with ST5.5x25 dovetail self-tapping screws. At the same time, sealant is applied at the connecting parts 312 to further improve the sealing and waterproof performance. The drainage channels of each trough 31 are connected through each other, and each trough 31 is connected to multiple downpipes 34.

[0082] Example 2

[0083] Compared with Embodiment 1, end caps 32 are provided at opposite ends of each tank 31 to block the drainage tank.

[0084] Example 3

[0085] The photovoltaic solar greenhouse adopts a four-sided sealing design, that is, multiple grooves 31 are set on the perimeter of the roof structure 1. At the ridge, two grooves 31 with different inclination directions are connected by a second adapter 33b. At the corners, two grooves 31 with different orientations are connected by a first adapter 33a. The adapter groove 331 of each first adapter 33a is connected to a downpipe 34, that is, a total of 4 downpipes 34 are set.

[0086] In this invention, the trough 31 is directly fixed to the solar canopy without the need for additional welded brackets, reducing the types of materials and construction procedures, and maximizing the integration of photovoltaics into buildings. The horizontal beam 11 and vertical beam 12 on the same side are flush, allowing for a perimeter drainage trough sealing around the roof structure 1. The trough 31 is also designed to accommodate larger drainage volumes, tolerate a certain degree of water splashing, and maintain aesthetic appeal, resulting in a more harmonious and unified appearance after installation, meeting the needs of more customers and expanding its application scenarios. The entire structure only requires a single level of waterproofing to achieve drainage for the entire photovoltaic system. Compared to the traditional four-level drainage system of photovoltaic solar canopies, this eliminates the need for a longitudinal first-level water trough, a transverse second-level water trough, and a longitudinal third-level water trough, simplifying the drainage system, reducing the types of materials, and lowering costs.

[0087] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
