Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to photovoltaic equipment technical field, concretely relates to a waterproof cover plate and fastener. BACKGROUND
[0002] In photovoltaic systems, ensuring the waterproof performance between modules is crucial; traditional photovoltaic installation structures often rely on relatively simple sealing methods when dealing with the seams between modules, which can increase the risk of rainwater leakage, especially in long-term exposure to natural environments; traditional solutions may include using sealants such as silicone to close the gaps, but this method has the problems of poor durability, easy aging and cracking, thereby affecting the reliability and life of the photovoltaic system.
[0003] Limitations of existing technology:
[0004] 1. Limited sealing effect: Traditional sealing methods such as silicone sealing may have problems such as aging and cracking after long-term use, leading to sealing failure, allowing rainwater to penetrate through the seams between photovoltaic modules.
[0005] 2. High construction complexity: In order to achieve good sealing effect, additional manual operation and time are required for the application or installation of sealing materials, increasing construction cost and difficulty.
[0006] 3. Inconvenient maintenance: Once the sealing material has problems, it usually needs to be removed to repair or replace, increasing the cost and complexity of later maintenance.
[0007] 4. Poor economic efficiency: Due to the above problems, not only the initial installation cost is increased, but also additional costs may be incurred due to subsequent maintenance needs, reducing the economic efficiency of the entire system.
[0008] Therefore, the existing technology has limitations and needs further improvement. Utility model content
[0009] In view of the problems existing in the prior art, the utility model provides a waterproof cover plate and fastener.
[0010] To achieve the above purpose, the specific scheme of the utility model is as follows:
[0011] The utility model provides a waterproof cover plate and fastener, which comprises:
[0012] Waterproof cover plate, backing plate, bolt;
[0013] One end of the bolt is installed on the lower side of the waterproof cover plate;
[0014] The other end of the bolt passes through the backing plate and is fixed by a nut;
[0015] The waterproof cover plate is arranged above the joint between two photovoltaic modules, and the two sides of the waterproof cover plate are respectively overlapped on the upper surfaces of the left and right photovoltaic modules.
[0016] The supporting plate is arranged below the joint between two photovoltaic modules, and the two sides of the supporting plate are respectively overlapped on the lower surfaces of the left and right photovoltaic modules.
[0017] The waterproof cover plate and the supporting plate are respectively arranged above and below the photovoltaic module, the bolt passes through the joint between the two adjacent photovoltaic modules, and is used for fixing the waterproof cover plate and the supporting plate on the upper side and the lower side of the photovoltaic module, and the waterproof cover plate is used for preventing rainwater from leaking from the joint (gap) between the two adjacent photovoltaic modules.
[0018] Further, the waterproof cover plate is arc-shaped, and the middle part is higher than the two sides.
[0019] Further, the lower side of the waterproof cover plate is provided with L-shaped left and right clamping plates.
[0020] The left and right clamping plates are oppositely arranged.
[0021] The head of the bolt is detachably clamped between the left and right clamping plates.
[0022] Further, the cross section of the supporting plate is a concave type structure.
[0023] Further, the width of the supporting plate is greater than the span of the waterproof cover plate.
[0024] Further, the lower end of the screw rod of the bolt is provided with a thread matched with the nut.
[0025] The technical scheme of the utility model has the following beneficial effects:
[0026] 1. Enhance waterproof performance:
[0027] By adopting the arc-shaped waterproof cover plate, the middle part is higher than the two sides, which can effectively guide the rainwater to quickly drain along the arc surface, avoiding the possibility of water accumulation at the joint. This design not only improves the waterproof efficiency, but also reduces the potential corrosion and damage risk caused by water accumulation.
[0028] 2. Simplify installation and maintenance:
[0029] The L-shaped left and right clamping plates are introduced in the design, so that the bolt head can be conveniently clamped therebetween, realizing detachable fixation. This greatly simplifies the installation process, and also facilitates disassembly for inspection or replacement when needed, reducing maintenance cost and technical requirements.
[0030] 3. Improve structural stability:
[0031] The concave-like cross-sectional design of the support plate and its width greater than the span of the waterproof cover plate provide more stable support for the entire device; the support plate is located below the photovoltaic module, enhancing the rigidity and durability of the overall structure and ensuring long-term reliability.
[0032] 4. Optimize sealing effect:
[0033] The waterproof cover plate and the support plate are respectively lapped on the upper surface and the lower surface of the photovoltaic module, forming a double-sealing barrier, effectively preventing water from seeping from the joints; at the same time, since the material directly contacts the photovoltaic module, there is no need to add auxiliary materials such as sealant, reducing the risk of aging and cracking.
[0034] 5. Improve economic efficiency:
[0035] Compared with traditional sealing methods (such as using silicone), this design reduces the complexity of construction, shortens the installation time, and thus reduces the initial installation cost. In addition, due to its good durability and easy maintenance characteristics, it also reduces the later maintenance cost, improving the overall economic efficiency of the system.

[0048] One end of bolt 17 is installed on the lower side of waterproof cover 15;
[0049] The other end of bolt 17 passes through the supporting plate 16 and is fixed by nut;
[0050] The waterproof cover 15 is arranged above the joint between the two photovoltaic modules, and the two sides of the waterproof cover 15 are respectively overlapped on the upper surfaces of the photovoltaic modules on the left and right sides;
[0051] The supporting plate 16 is arranged below the joint between the two photovoltaic modules, and the two sides of the waterproof cover 15 are respectively overlapped on the lower surfaces of the photovoltaic modules on the left and right sides;
[0052] The waterproof cover plate 15 and the supporting plate 16 are respectively located above and below the photovoltaic module, the bolt 17 passes through the joint gap between the adjacent two photovoltaic modules, and is used for fixing the waterproof cover plate 15 and the supporting plate 16 on the upper side and the lower side of the photovoltaic module, and the waterproof cover plate 15 is used for preventing rainwater from leaking from the joint gap (gap) between the adjacent two photovoltaic modules.
[0053] The waterproof cover plate 15 is arc-shaped and higher in the middle than at both sides.
[0054] The lower side of the waterproof cover plate 15 is provided with L-shaped left clamping plates 18 and right clamping plates 19;

[0056] The head 20 of the bolt 17 is detachably clamped between the left clamping plates 18 and the right clamping plates 19.
[0057] The cross section of the supporting plate 16 is a concave type structure.
[0058] The width of the supporting plate 16 is greater than the span of the waterproof cover plate 15.
[0059] The lower end of the screw rod 21 of the bolt 17 is provided with a thread 22 matched with a nut.
[0060] The principle of the utility model is as follows:
[0061] The installation position and structure are as follows:
[0062] The waterproof cover plate 15 is arranged above the joint gap between the two adjacent photovoltaic modules, and the two sides are respectively overlapped on the upper surfaces of the left and right photovoltaic modules. The waterproof cover plate 15 is arc-shaped and higher in the middle than at both sides, which helps rainwater to flow outward along the arc surface and be discharged, and prevents water accumulation.
[0063] The supporting plate 16 is located below the joint gap between the two photovoltaic modules, and the two sides are respectively overlapped on the lower surfaces of the left and right photovoltaic modules. The cross section of the supporting plate 16 is a concave type structure, and the width is greater than the span of the waterproof cover plate 15, so as to provide additional support and stability.
[0064] The fixing mode is as follows:
[0065] The bolt 17 is connected in that one end of the bolt 17 is installed on the lower side of the waterproof cover plate 15, the other end passes through the supporting plate 16 and is fixed through a nut. The head 20 of the bolt 17 is clamped through the L-shaped left clamping plates 18 and the right clamping plates 19, so as to ensure the stability and detachability of the bolt 17. The lower end of the screw rod 21 of the bolt 17 is provided with a thread 22 matched with a nut for firm fixing.
[0066] The working process is as follows:
[0067] When it rains, the rainwater first falls on the surface of the photovoltaic module. Due to the design of the waterproof cover plate 15, the rainwater will be guided to both sides of the cover plate and naturally slide down along the arc surface to the outside, avoiding accumulation or leakage at the joint.
[0068] For a small amount of moisture that may enter the inside of the joint, the presence of the supporting plate 16 can further block the downward penetration of these moisture, while the concave-like structure of the supporting plate 16 can accommodate a small amount of moisture until they evaporate or are drained away.
[0069] Under the action of wind or other external forces, the photovoltaic module may be subjected to certain pressure or vibration, but because the waterproof cover plate 15 and the supporting plate 16 are tightly connected by the bolts 17, the entire system can effectively transmit this load to the photovoltaic module, maintaining the stability and safety of the system.
[0070] Maintenance convenience:
[0071] If it is necessary to inspect or replace the waterproof cover plate 15, the waterproof cover plate 15 can be easily removed without affecting the photovoltaic module itself by loosening the nuts, removing the bolts 17. Similarly, it is very convenient to install new parts, just reverse the above steps.
[0072] In summary, the utility model realizes efficient waterproof performance, stable structural support and convenient maintenance characteristics through ingenious design, and is particularly suitable for photovoltaic systems in outdoor long-term exposed environments, ensuring reliable operation and long-term durability of the system.
[0073] The above only describes the preferred embodiments of the utility model, and does not limit the utility model range of the utility model, any equivalent structural transformation made under the utility model concept of the utility model, or direct / indirect application in other related technical fields is included in the protection range of the utility model.
