Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module manufacturing, in particular to a waterproof assembly of a photovoltaic module. BACKGROUND

[0002] With the rapid development of renewable energy, the application range of photovoltaic modules is increasingly wide, not only being installed in traditional ground power stations, but also being increasingly integrated into diversified construction scenes such as carports, sunlight rooms, and photovoltaic building integrated roofs. In the installation process of photovoltaic modules, waterproofing has always been a technical problem in the industry. At present, the industry mainly adopts the following waterproof measures to deal with the water leakage problem between photovoltaic modules:

[0003] Firstly, a common method is to insert waterproof T-shaped adhesive strips between the gaps between photovoltaic modules. However, at the intersection of longitudinal and transverse adhesive strips, the transverse adhesive strip needs to be disconnected, which leads to the easy occurrence of gaps at the intersection, thereby reducing the waterproof effect. In addition, due to the installation error of photovoltaic supports and modules, the gap width between modules is often inconsistent, while the width of the waterproof adhesive strip is fixed, so at large gaps, the adhesive strip cannot be tightly packed, which easily causes water leakage problems.

[0004] Secondly, another common practice is to punch waterproof glue between the gaps between photovoltaic modules. Although this method can solve the water leakage problem to some extent, the durability of the waterproof glue is poor, and aging, falling off, etc. will occur within a few years, leading to waterproof failure. At the same time, the amount of waterproof glue used is large, and the price is not cheap, making the overall cost high.

[0005] In addition, there is also a waterproof system using longitudinal and transverse water guide channels. This method forms two waterproof barriers by laying a water guide channel under the gap between photovoltaic modules and laying a cover plate above the water guide channel. However, this method not only has a large amount of steel and high cost, but also the increased weight of the water guide channel further increases the amount of steel used in the photovoltaic support, leading to a further increase in the overall cost. In addition, the water guide channel is easily blocked by leaves, debris and other debris, affecting the drainage effect and causing water leakage problems.

[0006] Finally, there is also a method of customizing the module frame. By processing the module frame into a specific cross-sectional form in the factory, the modules can be tightly connected between them to achieve waterproof effect. However, this method requires the modules to be transported to the factory for processing, resulting in a long production cycle and affecting the construction progress of the photovoltaic project. At the same time, the cost of customizing the frame is high, resulting in a substantial increase in the cost of project construction.

[0007] In summary, the existing waterproof technology between photovoltaic modules has problems such as poor waterproof effect, high cost, complex production and installation, and poor durability. CONTENT OF THE INVENTION

[0033] Referring to Figure 1 , Figure 1 A structural diagram of a waterproof assembly of a photovoltaic module 5 in an embodiment of the present application is shown. The waterproof assembly of a photovoltaic module 5 provided in an embodiment of the present application comprises a support part 1, a filling part 2, a sealing part 3 and a protection part 4.

[0034] Specifically, the support part 1 comprises a mounting end 10 and two fixing ends 11 arranged on both sides of the mounting end 10. The mounting end 10 supports two adjacent photovoltaic modules 5 arranged at intervals, and a gap 6 is formed between the mounting end 10 and the two adjacent photovoltaic modules 5. The fixing ends 11 are used to tightly clamp one side of the photovoltaic module 5. The filling part 2 is filled at the bottom of the gap 6. The sealing part 3 is arranged above the filling part 2 in the gap 6. The protection part 4 covers the sealing part 3 and the two adjacent photovoltaic modules 5.

[0035] In the specific implementation process, the waterproof assembly forms a triple waterproof system through the combination of the support part 1, the filling part 2, the sealing part 3 and the protection part 4. First, the filling part 2 fills the bottom of the gap 6 to form a preliminary waterproof layer. Second, the sealing part 3 is tightly attached to the top of the filling part 2 to form a second waterproof barrier. Finally, the protection part 4 covers the entire waterproof structure to provide additional protection. This triple waterproof design ensures the waterproof performance of the gap 6 of the photovoltaic module 5 under extreme weather conditions.

[0036] Further, since each component is made of conventional and finished materials, secondary processing is not required, thereby reducing installation costs. In addition, local repair or replacement of the waterproof assembly is also very convenient. It only needs to remove the damaged part and replace it with a new assembly, without affecting the overall waterproof performance. Moreover, due to its excellent waterproof performance and easy maintenance characteristics, it ensures that the photovoltaic module 5 does not leak for a long time, reduces maintenance costs, and improves economic efficiency and reliability.

[0037] In one embodiment, the support part 1 comprises a mounting end 10 and two fixing ends 11 arranged on both sides of the mounting end 10. The mounting end 10 is designed with a flat surface for directly placing the photovoltaic module 5, ensuring that the photovoltaic module 5 is stable and horizontal. The fixing ends 11 can be designed in the form of buckles or other connection forms for tightly clamping one side of the adjacent photovoltaic module 5 to prevent displacement.

[0038] In one embodiment, the filling part 2 can be tightly filled at the bottom of the gap 6 between the adjacent photovoltaic modules 5, ensuring good sealing effect even when the photovoltaic modules 5 are slightly displaced due to thermal expansion and contraction.

[0039] In one embodiment, the sealing part 3 is arranged above the filling part 2, and the width of the sealing part 3 is slightly larger than the width of the gap 6, so as to ensure that an effective waterproof barrier can be formed after installation. At the same time, the material of the sealing part 3 needs to be selected considering the anti-aging performance, so as to ensure the durability of the waterproof effect.

[0040] In one embodiment, the protection part 4 covers the sealing part 3 and the two photovoltaic modules 5 on both sides, which mainly prevents external objects such as leaves and debris from damaging the sealing part 3, protects the sealing part 3, delays the aging of the sealing part 3, and improves the sealing effect.

[0041] In combination Figure 1 As shown in the figure, the figure is a structural schematic diagram of a waterproof assembly of a photovoltaic module 5 provided in an embodiment of the present application. In some embodiments, the mounting end 10 is a plate structure, and the plate structure and the two side walls of the two photovoltaic modules 5 form the gap 6.

[0042] Specifically, the mounting end 10 is arranged as a plate structure, and the mounting end 10 can be arranged as a supporting plate, and the material thereof can be selected from high-strength, corrosion-resistant aluminum alloy or stainless steel. The plate structure has sufficient flatness for directly supporting the photovoltaic module 5, so as to ensure that the photovoltaic module 5 remains in a horizontal state after installation. The plate structure and the two side walls of the two adjacent photovoltaic modules 5 naturally form the gap 6, which is the area that needs to be waterproofed.

[0043] In one embodiment, the filling part 2 is arranged at the bottom of the gap 6 and contacts the surfaces of the two side walls of the two adjacent photovoltaic modules 5 and the surface of the plate structure close to the photovoltaic module 5.

[0044] Specifically, the filling part 2 is arranged as a solid pearl wool strip. The solid pearl wool strip has excellent elasticity, weather resistance and waterproof performance, can be tightly attached to the bottom of the gap 6, contacts the surfaces of the two side walls of the two adjacent photovoltaic modules 5 and the surface of the plate structure close to the photovoltaic module 5, and forms an effective waterproof barrier. At the same time, the solid pearl wool strip also has good sound insulation and heat insulation effects, which helps to improve the overall performance of the photovoltaic module 5.

[0045] In one embodiment, the gap 6 is arranged in a longitudinal direction, and the filling part 2 is arranged in the longitudinal direction of the gap 6, so as to achieve comprehensive waterproof coverage.

[0046] In one of the embodiments, the gap 6 has an extended width, if the extended width of the gap 6 is d mm, the width D of the filling part 2 satisfies the relationship: D = d + 5 mm. This design ensures that the filling part 2 has a certain compression amount when filling the gap 6, which can tightly fit to each surface of the gap 6, and improve the waterproof effect. At the same time, the extra width of 5 mm also takes into account the possible small errors of the photovoltaic module 5 and the plate structure during installation, ensuring the applicability of the filling part 2.

[0047] In this embodiment, according to actual needs, other soft materials such as rubber strips and other materials with good durability of the same specification can also be used as substitutes.

[0048] As described above, by providing the filling part 2, the gap 6 between the photovoltaic module 5 and the mounting end 10 is effectively filled, achieving excellent waterproof effect. At the same time, the waterproof assembly also has the advantages of simple installation, easy maintenance, low cost, etc.

[0049] In combination Figure 1 As shown in the figure, it is a structure schematic diagram of the waterproof assembly of the photovoltaic module 5 provided in an embodiment of the present application. In some embodiments, the sealing part 3 is filled in the gap above the filling part 2, between the filling part 2 and the two side wall surfaces of the two adjacent photovoltaic modules 5, and between the filling part 2 and the surface of the plate structure close to the photovoltaic module 5.

[0050] Specifically, the sealing part 3 is filled with waterproof silicone sealant. The waterproof silicone sealant has excellent weather resistance, water resistance and chemical corrosion resistance, and can maintain stable waterproof performance for a long time. In this embodiment, the sealing part 3 is filled in the gap above the filling part 2 and between the filling part 2 and the two side wall surfaces of the two adjacent photovoltaic modules 5 and the surface of the plate structure close to the photovoltaic module 5, ensuring the integrity and continuity of the sealing, and improving the reliability of the sealing.

[0051] In this embodiment, the sealing part 3 is filled by pouring tool or manual method, and is poured along the gap above the filling part 2 and between the filling part 2 and the photovoltaic module 5 and the plate structure. During pouring, it is necessary to ensure that the sealant is uniformly distributed without bubbles and voids to form a continuous waterproof layer.

[0052] In this embodiment, in order to ensure the waterproof effect of the sealing part 3, the pouring thickness is not less than 10 mm, which ensures that the sealant can form a sufficient waterproof barrier after curing, effectively blocking the penetration of water and moisture. At the same time, the thick sealing layer can also provide a certain elasticity to adapt to the small displacement of the photovoltaic module 5 due to thermal expansion and contraction.

[0053] In combination Figure 1 As shown in the figure, Figure 1A structural schematic diagram of the waterproof assembly of the photovoltaic module 5 provided in an embodiment of the present application is shown. In some embodiments, the protection part 4 covers the sealing part 3 and the surface of the two adjacent photovoltaic modules 5 away from the mounting end 10, respectively.

[0054] Specifically, the protection part 4 is covered with modified asphalt waterproof coating on the sealing part 3 and the surface of the two adjacent photovoltaic modules 5 away from the mounting end 10, respectively. Modified asphalt coating is a high-performance waterproof material with excellent waterproof effect, durability and anti-aging performance, which can effectively protect the underlying silicone sealant from environmental factors such as ultraviolet light, rain, humidity, etc., thereby delaying the aging process of the sealant. Moreover, modified asphalt coating has good workability and can be quickly constructed by brushing, spraying and other methods, greatly shortening the construction period. At the same time, compared with other waterproof materials, modified asphalt coating has a lower price, reducing the cost of waterproofing.

[0055] In this embodiment, in order to protect the sealing part 3 from the edge effect and ensure the overall coverage of the surface of the photovoltaic module 5, the coverage width between the protection part 4 and the surface of the photovoltaic module 5 away from the mounting end 10 is not less than 10 mm, ensuring the sufficient extension of the protection part 4 on the surface of the photovoltaic module 5, forming a continuous waterproof layer.

[0056] In this embodiment, in order to ensure the waterproof effect of the protection part 4 and the sufficient protection of the underlying sealing part 3, the thickness of the protection part 4 is not less than 4 mm. A thicker protection layer can provide a stronger waterproof barrier to effectively block the penetration of moisture.

[0057] In combination with Figure 2 as shown, Figure 2 A structural schematic diagram of the support part 1 provided in an embodiment of the present application is shown. In some embodiments, the fixed end 11 includes a first section 110 and a second section 111.

[0058] Specifically, the fixed end 11 is composed of the first section 110 and the second section 111, forming a U-shaped buckle structure. One end of the first section 110 is longitudinally arranged on both sides of the mounting end 10. The other end of the first section 110 is connected with the second section 111 arranged transversely, together forming a U-shaped buckle structure that can be tightly clamped on one side of the photovoltaic module 5, effectively fixing the photovoltaic module 5 and improving the installation stability and safety of the photovoltaic module 5, with a simple structure and easy installation.

[0059] In this embodiment, the second section 111 serves as the transverse part of the buckle, having sufficient extension length and strength to ensure that the photovoltaic module 5 can be firmly clamped to prevent it from falling off or shaking.

[0060] In the embodiment, the length of the buckle is not less than 50 mm, and the wall thickness is not less than 2 mm. The cross-sectional shape of the buckle can be adjusted according to actual needs to meet different installation requirements.

[0061] In the embodiment, at least three support parts 1 are respectively arranged at the lower edges of the frames of two adjacent photovoltaic modules 5, and need to be arranged uniformly and equidistantly to ensure that the photovoltaic modules 5 can be kept in a horizontal state during installation, and reduce deformation or damage caused by uneven stress.

[0062] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0063] The above embodiments only express several implementation manners of the application, the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, several modifications and improvements can be made, which belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
