Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a novel waterproof guide rail. Background Technology

[0002] Currently, photovoltaic panel drainage systems on the market mainly rely on two types of water tank systems: the four-level water tank system and the M-level water tank system. These two systems have been proven to be mature and effective in practical applications, but they also have some obvious limitations, especially in terms of material costs, construction complexity, and waterproof performance.

[0003] The shortcomings of existing technology:

[0004] Level 1 and Level 4 water tanks:

[0005] 1. The specifications of water tanks vary at different levels, resulting in poor versatility and easy confusion in on-site use.

[0006] 2. It occupies the space under the beam, reduces the headroom, and affects the aesthetics;

[0007] 3. Key joints are glued together, and their waterproof performance and durability under sunlight, high temperatures, and rain impacts need to be verified. Over long-term operation, replacement or repair costs will be high.

[0008] 4. Multi-stage drainage increases system complexity, and maintenance costs and leakage risks increase simultaneously.

[0009] II. M-shaped water tank:

[0010] 1. Its application scenarios are very limited, so under the current system it is mostly used as a supplement to the four-level water tank and is mostly used when the components are arranged horizontally;

[0011] 2. The cross-section of the M-shaped water tank is complex, and it is rarely produced in general factories, which increases the difficulty of sourcing and using materials.

[0012] 3. It is divided into two subsystems: M-channel + pressure plate combination + bracket + wedge clamp and M-channel + self-tapping screw + crossbeam + pressure block. Both have the problem of too many installation accessories, which makes the maintenance and replacement of photovoltaic modules more difficult. The pressure plate type cannot adapt to various purlin heights and cannot meet diverse needs. The pressure block type generally presses down on the short side of the photovoltaic module to fix it, but it may be unreliable and not secure under extreme conditions compared to pressing down on the long side of the module. Moreover, the self-tapping screws may also loosen, which poses a safety risk.

[0013] III. High material costs:

[0014] The existing four-level water tank system and M-level water tank system account for as much as 35% to 50% of the total steel consumption in the project, which leads to huge raw material costs. Since these water tanks are mainly used for drainage and do not involve structural safety issues, there is a lot of room for cost reduction while ensuring functionality.

[0015] IV. High construction complexity:

[0016] The installation process of the existing system is relatively complex, requiring precise placement of multiple components to ensure waterproofing, which increases the difficulty of construction and time costs.

[0017] 5. Limited waterproof performance:

[0018] Although existing water tank systems can achieve a certain drainage function, they are still insufficient in preventing leakage. For example, in the face of extreme weather conditions, water may accumulate and fail to drain in time or seep in, affecting the working efficiency and lifespan of photovoltaic modules.

[0019] 6. Lack of natural drainage design:

[0020] The existing system fails to make full use of natural slopes for effective drainage, relying more on artificial construction measures to complete the drainage task. This not only increases the complexity of the system, but also reduces its economic efficiency and environmental friendliness.

[0021] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0022] In view of the problems existing in the prior art, this utility model provides a new type of waterproof guide rail.

[0023] To achieve the above objectives, the specific solution of this utility model is as follows:

[0024] This utility model provides a novel waterproof guide rail, comprising:

[0025] Upper wing plate, lower wing plate, water guide strip, outer support, inner support, left fixed edge, right fixed edge, upper support plate, lower support plate;

[0026] The upper support plate and the lower support plate are arranged horizontally, with the lower support plate located below the upper support plate. The left fixed side and the right fixed side are arranged vertically below the lower support plate, and the outer support and the inner support are arranged vertically between the upper support plate and the lower support plate.

[0027] The left and right fixed sides are used to mount the guide rail onto the purlin;

[0028] The lower wing plate is located on the left side of the lower support plate;

[0029] Water guide strips and upper wing plates are respectively provided on the left and right sides of the upper support plate;

[0030] The upper side of the upper wing plate is used to support the long side of the photovoltaic module located at a relatively high slope.

[0031] The upper side of the lower wing plate is used to support the long side of the photovoltaic module located at a relatively low slope.

[0032] The guide rail is set along the long side of the photovoltaic module to fix the photovoltaic module in a tile-like manner from high to low. Water flows from the upper surface of the photovoltaic module located at the higher slope to the water guide strip, and then from the water guide strip to the upper surface of the photovoltaic module located at the lower slope.

[0033] Furthermore, the water guide strip is provided with a limiting protrusion to restrict the photovoltaic modules at higher positions from sliding down.

[0034] Furthermore, a waterproof sealant is provided between the lower side of the water guide strip and the photovoltaic module;

[0035] Rainwater flows along the top of the guide strip to the upper surface of the photovoltaic module where the slope is relatively low, in a tiered manner.

[0036] Furthermore, the upper surface of the water guide strip is also provided with a fixing angle steel to prevent the photovoltaic module located at a relatively high slope from sliding downwards.

[0037] Furthermore, the lower wing plate and the upper wing plate are both provided with serrated patterns on their lower sides.

[0038] Furthermore, the guide rail also includes a guide rail clamp, which is C-shaped and includes an upper side and a lower side. The upper side of the lower side and the lower side of the upper side are both provided with serrated patterns.

[0039] Guide rail clamps are provided on both the upper and lower wing plates;

[0040] The upper edge of the guide rail clamp is used to press down the long frame of the photovoltaic module, and the lower edge of the guide rail clamp engages with the serrated patterns on the lower side of the upper and lower wing plates through the serrated patterns to form a clamping and fixing.

[0041] The technical solution of this utility model has the following beneficial effects:

[0042] 1. The system is simplified and highly versatile, while ensuring reliable fixing of photovoltaic modules and making maintenance and replacement simpler, which inevitably improves economic efficiency;

[0043] 2. Photovoltaic modules have a smooth glass surface, making them extremely suitable for natural drainage;

[0044] 3. The water-facing side is exposed, and waterproof sealant can be applied in multiple places as a second layer of waterproofing. The operation is simple, the reliability of waterproofing is greatly improved, and leak detection, repair and maintenance are clear at a glance.

[0045] 4. Optimize drainage performance:

[0046] The guide rail is designed with a natural drainage path from high to low, mimicking the way tiles are stacked, so that rainwater can flow smoothly from the photovoltaic modules located on a relatively high slope to the low slope and eventually be discharged. This design not only improves drainage efficiency, but also reduces the risk of water accumulation and leakage, thereby enhancing the waterproof performance of the system.

[0047] 5. Enhances fixation stability:

[0048] The water guide strip is equipped with limit protrusions or fixing angle steel. These structures effectively prevent the photovoltaic modules at high positions from sliding due to gravity or external forces, ensuring the stability and safety of the photovoltaic modules under various environmental conditions.

[0049] 6. Improve waterproof reliability:

[0050] Waterproof sealant was applied between the water guide strip and the photovoltaic module, further strengthening the waterproof barrier, preventing rainwater from seeping through gaps, improving the overall waterproof performance of the system, protecting the photovoltaic module from moisture damage, and extending its service life.

[0051] 7. Simplified installation process:

[0052] The serrated design of the upper and lower wing plates, along with the C-shaped guide rail clamps used in conjunction, makes the installation of photovoltaic modules simple and quick. The upper and lower edges of the guide rail clamps press against the long frame of the photovoltaic module and engage with the wing plates to form a tight fixation, ensuring both the convenience of installation and the firmness of the fixation.

[0053] 8. Reduce material costs:

[0054] The design of the new waterproof guide rail takes into account the economy of materials, reducing unnecessary material usage and lowering production costs through a reasonable structural layout. At the same time, its ease of installation indirectly reduces construction time and labor costs, thereby improving the project's economic benefits. Attached Figure Description

[0082] The principle of this utility model is as follows:

[0083] Guide rail structure and installation

[0084] This new type of waterproof guide rail consists of several key components, including an upper wing plate 1, a lower wing plate 2, a water guide strip 3, an outer support 4, an inner support 5, a left fixed edge 6, a right fixed edge 7, an upper support plate 8, and a lower support plate 9. These components, through a specific layout, achieve effective support, fixation, and natural drainage for the photovoltaic modules.

[0085] Installation position: The left fixed side 6 and the right fixed side 7 are vertically arranged on the lower support plate 9 and are used to install the entire guide rail system on the purlin 10.

[0086] Support structure: The outer support 4 and the inner support 5 are vertically arranged between the upper support plate 8 and the lower support plate 9 to provide support and ensure structural stability.

[0087] Fixed photovoltaic modules

[0088] High-mounted photovoltaic modules: The upper wing plate 1 is located on the right side of the upper support plate 8, and its upper side is used to support the long side of the photovoltaic module located at a relatively high slope. The upper side 13 of the guide rail clamp 12 (C-shaped) presses down on the long frame of the photovoltaic module, while the serrated pattern of the lower side 14 of the guide rail clamp 12 engages with the serrated pattern on the lower side of the upper wing plate 1 to form a tight fixation.

[0089] Low-lying photovoltaic modules: The lower wing plate 2 is located on the left side of the lower support plate 9, and its upper side is used to support the long side of the photovoltaic module located at the relatively low slope. Similarly, the upper and lower edges 14 of the guide rail clamp 12 are used in conjunction with the lower wing plate 2 to achieve a firm fixation of the photovoltaic module.

[0090] Drainage mechanism

[0091] Water flow path: Rainwater first falls on the surface of the photovoltaic module located on a relatively high slope, and then flows along the surface into the water guide strip 3. The water guide strip 3 is arranged along the long side of the photovoltaic module. Rainwater flows along the water guide strip 3 to the upper surface of the photovoltaic module on a relatively low slope, and so on, until the rainwater is discharged from the eaves, forming a natural drainage path.

[0092] Waterproofing measures: To prevent rainwater leakage, a waterproof sealant is installed between the lower side of the water guide strip 3 and the photovoltaic module, ensuring that water will not penetrate to the bottom of the module. In addition, the limiting protrusion of the water guide strip 3 and the fixing angle steel 11 prevent the photovoltaic module from sliding down due to its own weight or external force, further ensuring the stability of the system.

[0093] Anti-slip design

[0094] Limiting protrusions: The limiting protrusions on the water guide strip 3 can effectively limit the downward movement of photovoltaic modules at high positions, increasing the safety of the system.

[0095] Fixed angle steel 11: The upper surface of the water guide strip 3 is also provided with fixed angle steel 11 as an additional safety barrier to prevent the photovoltaic modules at high positions from sliding down.

[0096] Ease of installation

[0097] Serrated design: The lower sides of both the upper wing plate 1 and the lower wing plate 2 are provided with serrated patterns. Combined with the serrated patterns of the guide rail clamp 12, the installation process is simpler and faster, while ensuring the stable fixation of the photovoltaic modules.

[0098] In summary, the novel waterproof guide rail proposed in this utility model achieves efficient photovoltaic module fixing and natural drainage functions through reasonable structural design. It not only improves the waterproof performance and stability of the system, but also simplifies the installation process, reduces material costs, and is suitable for various types of photovoltaic module installation scenarios.
