[0002] The installation of photovoltaic modules usually involves aesthetics and waterproofing. In the past few years, photovoltaic technology has been widely used and developed, so the requirements for aesthetics and waterproofing have become increasingly higher.

[0003] In the existing technology, the gaps between photovoltaic modules often use galvanized aluminum-magnesium materials such as water tanks as drainage components, but because the rigidity and strength of the components are not very stable under external forces, they are prone to deformation, bending and twisting, thereby increasing the probability of roof leaks in heavy rain and flood weather. In addition, drainage components are usually inserted into the gaps after the module construction is completed, causing the components, which are not very rigid, to be easily deformed, reducing their efficiency and increasing operation and maintenance costs.

[0014] Preferably, the main water tank has a longitudinal lower water retaining edge and a longitudinal upper water retaining edge, and the longitudinal lower water retaining edge is higher than the longitudinal upper water retaining edge.

[0015] Preferably, the lower end of the longitudinal beam is connected to a limiting column that cooperates with the main water tank to limit the position.

[0016] The utility model adopts the above technical solution and has the following beneficial effects:

[0017] 1. The flowing water in the horizontal water guide groove is sent into the longitudinal water guide groove, and the water is discharged to the longitudinal lower side by the longitudinal water guide groove. In this way, the convergence speed can be accelerated with the help of the inclination angle of the longitudinal water guide groove itself, which is conducive to accelerating the drainage. In addition, the block assembly fixes the crossbeam, the longitudinal water guide groove and the photovoltaic module together, and the block assembly and the longitudinal water guide groove are separately, or the block assembly and the longitudinal water guide groove are simultaneously provided with a load-bearing part supporting the photovoltaic module, so as to cooperate in supporting the photovoltaic module. Therefore, the longitudinal water guide groove has both drainage and load-bearing functions, and after being fixed as a whole with the crossbeam and the photovoltaic module, it is not easy to bend and twist, which can solve the problems of water leakage caused by bending and twisting of the water tank in the prior art, improve the waterproof performance of the photovoltaic power station, and reduce the frequency and maintenance cost.

[0018] 2. The crossbeam and the longitudinal water channel are fixed together by the cooperation of the lower pressing block and the pressing block connector, and the longitudinal water channel and the photovoltaic module are fixed together by the lower pressing block, the upper pressing block and the pressing block fastener. Therefore, the weight of the photovoltaic module is transferred to the crossbeam through the longitudinal water channel as a medium, that is, the pressing block assembly not only fixes the longitudinal water channel on the crossbeam, but also fixes the photovoltaic module on the longitudinal water channel, which plays a load-bearing role and improves the overall structural strength of the longitudinal water channel. Since the crossbeam, the longitudinal water channel and the pressing block assembly form a layered installation structure, the longitudinal water channel is not easy to deform.

[0019] 3. The upper transverse part and the lower transverse part are fixed to the inner folded edge by fastening bolts, which not only presses and fixes the longitudinal water guide groove on the beam, but also fixes the position of the lower pressure block, thereby enhancing the reliability of fixation and preventing the photovoltaic module from loosening easily.

[0020] 4. Use the lower support part as the load-bearing part to support the photovoltaic module, and transfer the weight of the photovoltaic module to the crossbeam through the longitudinal water guide groove and the pressure block connector; tighten the pressure block bolts, and the lower pressure block supports the bottom of the photovoltaic module while the upper pressure block presses the upper side of the photovoltaic module.

[0021] 5. The lower fixing part is fixed to the crossbeam with self-tapping screws to improve construction efficiency and ensure reliable fixation.

[0022] 6. Since the longitudinal water guide groove also has the function of bearing and supporting the photovoltaic modules, the longitudinal water guide groove and the longitudinal beam are spaced apart in the lateral direction so that the longitudinal water guide groove and the longitudinal beam can provide dispersed support to the photovoltaic modules in the lateral direction and ensure the stability of the photovoltaic modules.

[0023] 7. The eaves can guide the water in the horizontal water channel to flow to the longitudinal water channel to avoid splashing out of the longitudinal water channel. The longitudinal side of the horizontal water channel has a water retaining function and supports the bottom surface of the photovoltaic module frame at the same time, so the horizontal water channel can assist in supporting the photovoltaic module.

[0024] 8. The lower end of the longitudinal water guide groove is connected to the main water guide groove. In this way, the water flows from the transverse water guide groove to the longitudinal water guide groove first, and then from the longitudinal water guide groove to the main water guide groove, forming a clearly defined drainage path, which is conducive to speeding up drainage and avoiding leakage.

[0025] 9. The main water tank has a longitudinal lower water retaining edge and a longitudinal upper water retaining edge, and the design makes the longitudinal lower water retaining edge higher than the longitudinal upper water retaining edge. In this way, on the one hand, because the main water tank is installed obliquely, the longitudinal lower water retaining edge is higher than the longitudinal upper water retaining edge to prevent water from overflowing, and on the other hand, the bottom surface of the lower end of the longitudinal water guide groove is supported on the longitudinal upper water retaining edge. At the same time, the lower end of the longitudinal water guide groove is close to the longitudinal lower water retaining edge, and the water flowing out of the lower end of the longitudinal water guide groove will be blocked by the longitudinal lower water retaining edge to prevent splashing out of the main water tank.

[0026] 10. The lower end of the longitudinal beam is connected with a limit column that cooperates with the main water tank limit, so that the main water tank is fixed to the lower end of the longitudinal beam through the limit of the limit column, without the need for additional fasteners.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0037] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0041] In the photovoltaic sun room in the prior art, several photovoltaic modules are arranged in a rectangular array and installed on a photovoltaic bracket, usually tilted longitudinally and facing the direction of the sun. The photovoltaic bracket includes several longitudinal beams and several cross beams vertically crossed above the longitudinal beams, and the photovoltaic modules are arranged on the cross beams.

[0042] Embodiment 1

[0043] Reference Figures 1 to 6As shown, in this embodiment, a photovoltaic module drainage structure 2 with both drainage and load-bearing functions is provided, and the photovoltaic module drainage structure 2 includes a longitudinal water guide groove 21 and a transverse water guide groove 22. The longitudinal water guide groove 21 is vertically cross-arranged on the crossbeam 12 and is arranged below the adjacent parts of the photovoltaic modules 100 on both sides of the transverse direction, and the transverse water guide groove 22 is vertically cross-arranged on the longitudinal beam 11 and is arranged below the adjacent parts of the photovoltaic modules 100 on both sides of the longitudinal direction. The end of the transverse water guide groove 22 is connected to the longitudinal water guide groove 21, and the flowing water in the transverse water guide groove is sent to the longitudinal water guide groove. The photovoltaic module drainage structure 2 also includes a block assembly, and the block assembly fixes the crossbeam 12, the longitudinal water guide groove 21 and the photovoltaic module 100 together. In addition, the block assembly is provided with a load-bearing part supporting the photovoltaic module, or the longitudinal water guide groove may also be provided with a load-bearing part supporting the photovoltaic module, or the block assembly and the longitudinal water guide groove may be provided with a load-bearing part at the same time.

[0044] It can be understood that in addition to being arranged below the adjacent parts of the photovoltaic components on the two adjacent longitudinal sides, the longitudinal water guide grooves are also arranged below the outer edges of the photovoltaic components on the two lateral sides to receive the water falling from the lateral outer photovoltaic components.

[0045] In the above technical solution, the flowing water in the horizontal water guide groove is sent into the longitudinal water guide groove, and the water is discharged to the longitudinal lower side by the longitudinal water guide groove. With the help of the inclination of the longitudinal water guide groove itself, the convergence speed is accelerated, which is conducive to accelerating the drainage. In addition, the block assembly fixes the crossbeam, the longitudinal water guide groove and the photovoltaic module together, and the block assembly and the longitudinal water guide groove are separately, or the block assembly and the longitudinal water guide groove are simultaneously provided with a load-bearing part supporting the photovoltaic module, so as to cooperate in supporting the photovoltaic module. Therefore, the longitudinal water guide groove has both drainage and load-bearing functions, and after being fixed as a whole with the crossbeam and the photovoltaic module, it is not easy to bend and twist, which can solve the problems of water leakage caused by bending and twisting of the water tank in the prior art, improve the waterproof performance of the photovoltaic power station, and reduce the frequency and maintenance cost.

[0046] Reference Figures 4 to 6As shown, in this embodiment, the pressing block assembly includes a pressing block connector 24, a lower pressing block 25, an upper pressing block 26 and a pressing block fastener 27. The pressing block connector 24 is connected to the cross beam 12, the lower pressing block 25 and the pressing block connector 24 are connected to the longitudinal water guide groove 21, the pressing block fastener 27 connects the lower pressing block 25 and the upper pressing block 26, the lower pressing block 25 is supported under the photovoltaic module, and the upper pressing block 26 presses the upper side of the photovoltaic module. In this way, the crossbeam 12 and the longitudinal water trough 21 are fixed together by the cooperation of the lower pressing block 25 and the pressing block connector 24, and the longitudinal water trough 21 and the photovoltaic module 100 are fixed together by the lower pressing block 25, the upper pressing block 26 and the pressing block fastener 27. Therefore, the weight of the photovoltaic module is transferred to the crossbeam with the longitudinal water trough 21 as the medium. That is, the pressing block assembly not only fixes the longitudinal water trough to the crossbeam, but also fixes the photovoltaic module to the longitudinal water trough, which plays a load-bearing role and improves the overall structural strength of the longitudinal water trough.

[0047] Further, the longitudinal water guide groove 21 has transverse side edges on both sides, and the upper ends of the transverse side edges are provided with inner folding edges 211, the lower pressing block 25 is provided with a lower transverse portion 251, and the pressing block connector 24 is provided with an upper transverse portion 243, and the lower transverse portion 251 and the upper transverse portion 243 are correspondingly arranged on the lower side and the upper side of the inner folding edge 211 and connected with fastening bolts 245. Among them, the inner folding edge is provided with fixing holes corresponding to the fastening bolts. In the above technical scheme, the upper transverse portion and the lower transverse portion are fixed to the inner folding edge by fastening bolts, which not only presses and fixes the longitudinal water guide groove on the crossbeam, but also fixes the position of the lower pressing block, enhances the reliability of the fixation, and the photovoltaic module is not easy to loosen. The pressing block fastener 27 is a pressing block bolt, so that when the pressing block bolt is tightened, the lower pressing block is supported under the photovoltaic module while the upper pressing block presses the upper side of the photovoltaic module. It can be understood that the inner folding edge can also be used as a load-bearing portion to support the bottom surface of the photovoltaic module, and then cooperate with the pressing block assembly to fix the photovoltaic module.

[0048] Specifically, the top of the lower pressing block 25 is provided with a lower supporting portion 254 that matches the bottom surface of the photovoltaic module frame, and the two sides of the lower pressing block 25 are provided with lateral portions 252 connected to the lower transverse portion, and an oblique portion 253 is provided between the lower supporting portion and the lateral portion. That is, the photovoltaic module is supported by the lower supporting portion as a load-bearing portion, and the weight of the photovoltaic module is transferred to the crossbeam through the longitudinal water guide groove and the pressing block connector. The pressing block connector 24 is provided with a vertical portion 242 connected to the upper transverse portion and a lower fixing portion 241 connected to the lower end of the vertical portion, and the lower fixing portion 241 is fixed to the crossbeam 12 by a self-tapping screw 244. Improve construction efficiency and ensure reliable fixation.

[0049] Furthermore, the longitudinal water guide groove 21 and the longitudinal beam 11 are spaced apart in the transverse direction. Since the longitudinal water guide groove also has the function of bearing and supporting the photovoltaic module, the longitudinal water guide groove and the longitudinal beam are spaced apart in the transverse direction so that the longitudinal water guide groove and the longitudinal beam can be combined to disperse the support of the photovoltaic module in the transverse direction. The end of the transverse water guide groove is provided with a water drop eave 222 that extends downwardly into the longitudinal water guide groove. The water in the transverse water guide groove is guided to flow into the longitudinal water guide groove to avoid splashing out of the longitudinal water guide groove. The longitudinal sides of the transverse water guide groove are provided with longitudinal side edges 221, which have a water retaining function and support the bottom surface of the frame of the photovoltaic module at the same time, so that the transverse water guide groove can assist in supporting the photovoltaic module.

[0050] Embodiment 2

[0051] On the basis of the first embodiment, a main water trough 23 is provided at the lower longitudinal direction of the photovoltaic module 100, and the lower end of the longitudinal water guide groove 21 is connected to the main water trough 23. In this way, the water flow first converges from the transverse water guide groove to the longitudinal water guide groove, and then converges from the longitudinal water guide groove to the main water trough, forming a well-defined drainage path, which is conducive to accelerating drainage and avoiding leakage.

[0052] Specifically, the main water trough 23 has a longitudinal lower water retaining edge 231 and a longitudinal upper water retaining edge 232, and the longitudinal lower water retaining edge is designed to be higher than the longitudinal upper water retaining edge. In this way, on the one hand, because the main water trough is installed obliquely, the longitudinal lower water retaining edge is higher than the longitudinal upper water retaining edge to prevent water from overflowing, and on the other hand, the bottom surface of the lower end of the longitudinal water guide trough is supported on the longitudinal upper water retaining edge, and at the same time, the lower end of the longitudinal water guide trough is close to the longitudinal lower water retaining edge, and the water flowing out of the lower end of the longitudinal water guide trough will be blocked by the longitudinal lower water retaining edge to prevent splashing out of the main water trough.

[0053] It is understandable that the lower edge of the photovoltaic assembly on the lower longitudinal side is located above the main water tank and is a certain distance away from the lower longitudinal water retaining edge, so that the water falling directly from the photovoltaic assembly on the lower longitudinal side can flow directly into the main water tank.

[0054] Furthermore, the lower end of the longitudinal beam 11 is connected with a limiting column 13 that is limited with the main water tank 23. The longitudinal beam and the limiting column are both square steel pipes, and the limiting column is welded and fixed to the lower end surface of the longitudinal beam. Through the limiting of the limiting column, the main water tank is fixed to the lower end of the longitudinal beam without the need for additional fasteners.

[0055] It is understandable that drainage pipes can be connected to multiple locations in the middle and both sides of the main water tank to drain the water flowing into the main water tank.

[0056] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
