Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a sealed rainproof structure for a rooftop photovoltaic power station. [Background technology]

[0002] The existing waterproofing methods for photovoltaic power stations include adding water guide grooves or filling silicone weatherproof sealant in the gaps between components. The method of adding water guide grooves will increase the cost of the power station and add several construction processes, which will extend the completion time of the power station. In addition, improper installation of the water guide groove will cause the risk of rain leakage, and dust collection over time will also affect the waterproofing effect. The method of filling silicone weatherproof sealant cannot be constructed on the components and can only be completed under the truss. The construction is difficult and the sealing effect will be reduced over time. There is also the risk of rain leakage, which cannot fundamentally solve the problem.

[0003] Currently, there is a solution of installing a waterproof cover plate at the gap between components, but the waterproof cover plate has the defects of unreliable sealing and easy to leak rain. [Contents of the utility model]

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A sealed rainproof structure for a rooftop photovoltaic power station that is easy to install, comprising a photovoltaic module and a mounting beam, wherein at least two photovoltaic modules are mounted side by side on the mounting beam, the photovoltaic module has a frame, the mounting beam is connected to a pressure plate assembly, the pressure plate assembly cooperates with the frame to fix the photovoltaic module to the mounting beam, the sealed rainproof structure comprises a waterproof slider and an inner slideway integrally arranged on the A surface of the frame of two adjacent photovoltaic modules, the waterproof slider is slidably cooperated with the inner slideway for installation, and the waterproof slider blocks the gap between the two adjacent photovoltaic modules after being installed in place.

[0007] Preferably, the waterproof slider includes a shielding portion that shields the gap between two adjacent photovoltaic modules and a sliding portion that extends downward from both sides of the shielding portion, and the sliding portion is slidably matched with the inner slideway.

[0008] Preferably, the inner slide includes an inner vertical portion protruding from the A surface of the photovoltaic component frame and an inner lateral portion protruding outward from the upper end of the inner vertical portion, and an inner slide groove is formed between the inner vertical portion and the inner lateral portion; the sliding portion includes an outer vertical portion and an outer lateral portion protruding inward from the lower end of the outer vertical portion, and an outer slide groove is formed between the outer vertical portion and the outer lateral portion, the inner lateral portion is slidably engaged with the outer slide groove, and the outer lateral portion is slidably engaged with the inner slide groove.

[0009] Preferably, the inner lateral portion, the inner slide groove, the outer lateral portion and the outer slide groove are all right-angled trapezoidal structures.

[0010] Preferably, the bottom surface of the waterproof slider is provided with a convex edge that cooperates with the A surface of the photovoltaic module.

[0011] Preferably, the waterproof slider is an integrally formed profile.

[0012] Preferably, the pressing plate assembly includes a pressing plate pressed onto the C surface of the photovoltaic assembly frame and a fastener connecting the pressing plate to the mounting beam.

[0013] Preferably, the fastener is a U-bolt, which is engaged with the mounting beam and connected to the pressure plate.

[0014] Preferably, the U-shaped bolt includes a U-shaped screw rod that is engaged with the mounting beam, and the pressure plate assembly also includes a clamping plate that is pressed onto the bottom surface of the mounting beam, and fixing holes are provided on the pressure plate and the clamping plate, and the mouth of the U-shaped screw rod faces downward and the screw rod head passes through the fixing holes on the pressure plate and the clamping plate in sequence and is connected with a nut.

[0015] Preferably, the C-surface of the photovoltaic assembly frame is provided with a fixed plane, the pressing plate is provided with a pressing portion pressed on the fixed plane, and the pressing plate is provided with an upwardly protruding shaped portion on a side away from the pressing portion.

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

[0017] 1. The sealed rainproof structure includes a waterproof slider and an inner slideway which is integrally arranged on the A surface of the frame of two adjacent photovoltaic modules. Since the waterproof slider and the inner slideway are installed by sliding, when installing on site, after the photovoltaic modules are installed in place, the waterproof slider is pushed to slide along the inner slideway. After the waterproof slider is slid and installed in place, the gap between the two adjacent photovoltaic modules is blocked. Thus, the waterproof slider and the inner slideway work together to form a sealed rainproof structure, so that the gap between the two photovoltaic modules is waterproof, and the waterproof effect will not weaken with the completion time. During the construction process, there is no need to install additional water guide grooves or additional glue. The waterproof slider does not need to be additionally fixed, less materials are used, the construction is convenient, and the waterproof effect is ahead of the traditional method of adding water guide grooves or filling silicone weather-resistant sealants in the gaps between modules, which reduces costs, improves the installation efficiency of photovoltaic systems, and thus speeds up the construction of power stations. It also avoids the impact on modules in the construction of waterproof structures in the prior art, reduces the probability of module damage, reduces the difficulty of construction, and effectively reduces the risks of construction personnel.

[0018] 2. The shielding part blocks the gap between two adjacent photovoltaic modules to prevent rainwater from directly entering the gap between two adjacent photovoltaic modules. The sliding part slides with the inner slide to realize the sliding installation of the waterproof slider. Since the sliding part extends downward from both sides of the width of the shielding part, on the one hand, it blocks the inner slide to prevent rainwater from entering; on the other hand, rainwater flows down from the shielding part and flows along the outer side of the sliding part to the frame of the photovoltaic module.

[0019] 3. The inner side portion is slidably engaged with the outer slide groove, wherein the outer side portion is slidably engaged with the inner slide groove to form an interlocking multiple waterproof structure, and the inner side portion, the inner slide groove, the outer side portion and the outer slide groove are all right-angled trapezoidal structures, which can further improve the waterproof effect.

[0020] 4. Because the waterproof slider does not need additional fixing, the installation of the waterproof slider can be completed after the waterproof slider is slid into place, without additional steps, which facilitates the installation of the waterproof slider. Therefore, the bottom surface of the waterproof slider is provided with a convex edge that matches the A surface of the photovoltaic module to increase the force between the waterproof slider and the A surface of the photovoltaic module to prevent the waterproof slider from loosening and falling off.

[0021] 5. The waterproof slider is an integrated profile, so it is easy to shape, which not only reduces the cost but also improves the installation efficiency of the photovoltaic system.

[0022] 6. Use U-bolts as fasteners. Only one bolt is needed. The mouth of the U-bolt faces downward and the screw head passes through the fixing holes on the pressure plate and the clamping plate in turn and is connected with a nut. Due to the limited space between the mounting beam and the bottom surface of the photovoltaic module, the operation of tightening the nut is performed under the mounting beam, which is convenient for tightening compared to the operation above.

[0023] 7. A fixed plane is provided on the C surface of the photovoltaic module frame, and a pressing plate is provided with a pressing portion pressed on the fixed plane. The pressing portion and the fixed plane have a large contact area. Under the tightening action of the fastener, the pressing portion presses the fixed plane to prevent loosening.

[0024] 8. Since the pressing plate is provided with an upwardly protruding U-shaped portion on the side away from the pressing part, it is ensured that the pressing plate can be effectively supported on the mounting beam on the side away from the pressing part, and it is beneficial for the pressing part to press and fix the plane.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0038] Embodiment 1

[0039] Reference Figures 1 to 3 As shown, a sealed rainproof structure of a rooftop photovoltaic power station that is easy to install includes a photovoltaic module 3 and a mounting beam 5. At least two photovoltaic modules 3 are installed side by side on the mounting beam 5. The mounting beam is usually a horizontal beam, and of course, it can also be a longitudinal beam. The photovoltaic module has a frame 2, and the frame has an A surface 21, a B surface 22, and a C surface 23. The mounting beam 5 is connected to a pressure plate assembly, and the pressure plate assembly cooperates with the frame to fix the photovoltaic module 3 to the mounting beam 5.

[0040] The sealed rainproof structure in this embodiment includes a waterproof slider 1 and an inner slide 24 integrally arranged on the A surface 21 of the frame of two adjacent photovoltaic components. The waterproof slider 1 is installed by sliding cooperation with the inner slide 24, and the waterproof slider 1 blocks the gap between the two adjacent photovoltaic components after being installed in place.

[0041] Since the waterproof slider and the inner slide are installed by sliding together, during on-site installation, after the photovoltaic module is installed in place, the waterproof slider is pushed to slide along the inner slide. After the waterproof slider is slid and installed in place, the gap between two adjacent photovoltaic modules is blocked, so that the waterproof slider and the inner slide work together to form a sealed rainproof structure, so that the gap between the two photovoltaic modules is waterproof, and the waterproof effect will not weaken with the completion time. During the construction process, there is no need to install additional water guide grooves or additional glue, and the waterproof slider does not need additional fixing. Less materials are used, the construction is convenient, and the waterproof effect is ahead of the traditional method of adding water guide grooves or filling silicone weather-resistant sealants in the gaps between modules, which reduces costs, improves the installation efficiency of photovoltaic systems, and thus speeds up the construction of power stations. It also avoids the impact on modules in the construction of waterproof structures in the existing technology, reduces the probability of module damage, reduces the difficulty of construction, and effectively reduces the risks of construction personnel.

[0042] Specifically, the waterproof slider 1 includes a shielding portion 11 that shields the gap between two adjacent photovoltaic modules and a sliding portion 12 that extends downward from both sides of the shielding portion, and the sliding portion 12 is slidably matched with the inner slide 24. The shielding portion shields the gap between two adjacent photovoltaic modules to prevent rainwater from directly entering the gap between the two adjacent photovoltaic modules, and the sliding portion is slidably matched with the inner slide to achieve the sliding installation of the waterproof slider. Since the sliding portion extends downward from both sides of the shielding portion, on the one hand, it is shielded in the inner slide to prevent rainwater from entering; on the other hand, after the rainwater flows down from the shielding portion, it flows along the outer side of the sliding portion to the frame of the photovoltaic module.

[0043] like Figure 2 and Figure 3 As shown, the inner slide 24 includes an inner vertical portion 241 protruding from the A surface of the photovoltaic module frame and an inner lateral portion 242 protruding from the upper end of the inner vertical portion to the outside, and an inner slide groove 243 is formed between the inner vertical portion and the inner lateral portion. The sliding portion 12 includes an outer vertical portion 121 and an outer lateral portion 122 protruding from the lower end of the outer vertical portion to the inside, and an outer slide groove 123 is formed between the outer vertical portion and the outer lateral portion. Among them, the inner lateral portion 242 is slidably engaged with the outer slide groove 123, and the outer lateral portion 122 is slidably engaged with the inner slide groove 243. And the inner lateral portion, inner slide groove, outer lateral portion and outer slide groove are all right-angled trapezoidal structures. A chimeric multi-waterproof structure is formed between the sliding portion and the inner slide, and the inner lateral portion, inner slide groove, outer lateral portion and outer slide groove are all right-angled trapezoidal structures, which can further improve the waterproof effect.

[0044] Furthermore, the bottom surface of the waterproof slider 1 is provided with a convex edge 14 that matches with the A surface 21 of the photovoltaic module. Because the waterproof slider does not need to be additionally fixed, the installation of the waterproof slider can be completed after the waterproof slider is slid into place without additional steps, thereby facilitating the installation of the waterproof slider. Therefore, the bottom surface of the waterproof slider is provided with a convex edge that matches with the A surface of the photovoltaic module to increase the force between the waterproof slider and the A surface of the photovoltaic module to prevent the waterproof slider from loosening and falling off.

[0045] In this embodiment, the waterproof slider 1 is an integrally formed profile, so it is convenient to form, which not only reduces the cost but also improves the installation efficiency of the photovoltaic system.

[0046] Specifically, the pressing plate assembly includes a pressing plate 4 pressed onto the C-surface 23 of the photovoltaic assembly frame and a fastener connecting the pressing plate to the mounting beam.

[0047] In this embodiment, the fastener is a U-bolt 6, which is engaged with the mounting beam 5 and connected to the pressure plate 4. The pressure plate 4 is provided with a fixing hole, and the U-bolt 6 includes a U-shaped screw that is engaged with the mounting beam 5. The pressure plate assembly also includes a clamping plate 62 pressed on the bottom surface of the mounting beam, and the clamping plate is also provided with a fixing hole. The mouth of the U-shaped screw faces downward, and the screw head passes through the fixing holes on the pressure plate and the clamping plate in turn and is connected with a nut. Since the space between the mounting beam and the bottom surface of the photovoltaic module is limited, the operation of tightening the nut is performed below the mounting beam, which is convenient for tightening relative to the operation above.

[0048] As a variation, the clamping plate is not provided, the mouth of the U-shaped screw faces upward, and the screw head passes through the fixing hole and is connected with a nut. Furthermore, a pad is provided between the nut and the pressing plate 4. The pad can increase the effective area of ​​the fastener pressing plate, avoid loosening, and increase the reliability of fastening.

[0049] The C surface 23 of the photovoltaic module frame is provided with a fixed plane, and the pressing plate 4 is provided with a pressing portion pressed on the fixed plane. The pressing portion is as wide as the pressing plate, but has a larger extension length, so that the pressing portion and the fixed plane have a larger contact area. Under the tightening action of the fastener, the pressing portion presses the fixed plane to prevent loosening.

[0050] like Figure 1 As shown, in this embodiment, the pressing plate 4 is provided with an upwardly protruding U-shaped portion 42 on the side away from the pressing portion to ensure that the pressing plate can be effectively supported on the mounting beam on the side away from the pressing portion and facilitate the pressing portion to press the fixing plane.

[0051] For the truss scheme for building across houses, the mounting beam 5 is installed on the truss, and the truss and the mounting beam are connected by welding or bolts. The truss is installed above the roof, that is, it completely spans the roof. Therefore, a photovoltaic power station can be built across houses to avoid being restricted by house quality and installation area. Of course, it can also be applied to other installation scenarios.

[0052] As an embodiment, the pressing plate 4 is a stainless steel profile, and the mounting beam 5 is a square steel or a U-shaped steel or a C-shaped steel. Compared with aluminum alloy materials, the cost is lower. It is understandable that other conventional materials and structures can also be used.

[0053] Embodiment 2

[0054] like Figure 4 As shown, on the basis of the first embodiment, a pressing and limiting structure is provided between the pressing plate 4 and the C surface 23 of the photovoltaic module frame.

[0055] Specifically, the pressing and limiting structure includes a limiting groove 26 provided on the C surface of the photovoltaic module frame, and a limiting pressing edge 44 provided on the pressing plate 4 and cooperating with the limiting groove. Among them, a limiting edge 25 is provided on the edge of the C surface of the photovoltaic module frame, so that a limiting groove 26 is formed between the limiting edge 25 and the B surface 22 of the photovoltaic module frame.

[0056] During installation, after the photovoltaic module is placed in place on the mounting beam, the pressure plate is placed so that the limiting pressure edge cooperates with the limiting groove, and then the pressure plate is fixed by fasteners so that the limiting pressure edge is pressed into the limiting groove. In addition, the pressing and limiting structure can not only press the photovoltaic module, but also play a limiting role to prevent the photovoltaic module from moving horizontally.

[0057] Embodiment 3

[0058] like Figure 5 As shown, the difference from the first embodiment is that in this embodiment, the pressing plate 4 is provided with a support portion 43 supported on the mounting beam on the side away from the pressing portion, and the U-shaped portion 42 is located between the pressing portion 41 and the support portion 43. The support portion is as wide as the pressing plate, but has a larger extension length, so that the support portion 43 has a larger contact area with the mounting beam. Under the tightening action of the fastener, the pressing portion 41 and the support portion 43 cooperate, which is conducive to the pressing portion 41 pressing the fixed plane of the C surface of the photovoltaic module frame.

[0059] 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.
