Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic waterproof structures, in particular to a U-shaped drainage trough. Background Art

[0002] In the existing drainage system, M-type drainage trough is a common drainage structure, such as Figure 1 and Figure 2 As shown, the drainage surface is relatively small. In extreme weather conditions such as heavy rain, this M-shaped gutter's drainage capacity is suboptimal and cannot quickly remove large amounts of accumulated water. This can not only lead to flooding but also damage the surrounding environment and facilities. Furthermore, the relatively high manufacturing cost of the M-shaped gutter has limited its widespread application. Utility Model Content

[0003] The purpose of the utility model is to provide a U-shaped drainage trough with a larger drainage cross-section, which can increase the drainage volume, and each plate surface is distributed with reinforcing ribs, which can effectively improve the structural strength.

[0004] To achieve the above-mentioned purpose, the solution of the present invention is: a U-shaped drainage trough, including a bottom plate, the left and right sides of the bottom plate are bent upward to form a left plate and a right side plate, the bottom plate and the left and right sides form a U-shaped main body, and the angle α between the bottom plate and each side plate is ≤95°; the side wall of each side plate bulges outward to form a wavy reinforcement rib extending along the length direction of the side plate.

[0005] Furthermore, the top of the left side plate is folded away from the right side plate to form a mounting portion; and the top of the right side plate is folded away from the left side plate to form a mounting portion.

[0006] Furthermore, the middle portion of the mounting portion protrudes downward to form a convex rib.

[0007] Furthermore, the wavy reinforcement ribs are of a constant-amplitude wavy structure.

[0008] Furthermore, the wavy reinforcement ribs are composed of a plurality of inclined reinforcement ribs connected end to end, and the angle δ between two adjacent inclined reinforcement ribs is 90°.

[0009] Furthermore, the side wall of each side plate protrudes outward to form a horizontal reinforcing rib extending along its length direction.

[0010] Furthermore, there are two horizontal reinforcing ribs on the side wall of each side panel, namely an upper horizontal reinforcing rib and a lower horizontal reinforcing rib. The upper horizontal reinforcing rib is connected to the crest of the wavy reinforcing rib, and the lower horizontal reinforcing rib is connected to the trough of the wavy reinforcing rib.

[0011] Furthermore, the bottom of the bottom plate is raised upward to form a ridge, and the top of the ridge is parallel to the bottom of the bottom plate.

[0012] After adopting the above solution, the beneficial effects of the utility model are:

[0013] The U-shaped gutter of this utility model optimizes its structural design by designing the angle α between the bottom plate and each side plate to be less than or equal to 95°. This maximizes the drainage cross-section of the U-shaped body and increases the drainage capacity of the gutter. This allows the gutter to more effectively drain accumulated water in actual use, with drainage capacity increased by approximately 57% compared to traditional M-shaped guttering. This is of great significance for responding to extreme weather conditions such as heavy rain, and can significantly reduce the impact of accumulated water on the surrounding environment and facilities.

[0014] Furthermore, the U-shaped drainage trough of the present invention is designed with wavy reinforcement ribs on the side walls of the side panels. These reinforcement ribs enhance the structural strength of the drainage trough, so that the material thickness can be reduced to a certain extent without affecting its structural strength during use, thereby ensuring its stability and durability in actual use.

[0015] Compared with the existing drainage trough structure, the U-shaped drainage trough of the utility model can save about 13% of material usage due to the reduction in material thickness, thereby reducing overall material costs and saving manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The utility model provides a U-shaped drainage trough, such as Figures 3 to 8 The structure comprises a base plate 1, the left and right sides of which are bent upward to form a left side plate 21 and a right side plate 22. The base plate 1, the left side plate 21, and the right side plate 22 form a U-shaped body, and the U-shaped body is used for drainage. When the size of the top opening of the drainage trough is fixed to match the size of the photovoltaic module 5, the angle α between the base plate 1 and each side plate 2 is designed to be less than or equal to 95°. This can maximize the drainage cross-section of the U-shaped body, increase the drainage capacity of the drainage trough, and enable the drainage trough to more effectively drain accumulated water in actual use.

[0031] The top of the left side plate 21 is folded away from the right side plate 22 to form a horizontal mounting portion 3; similarly, the top of the right side plate 22 is folded away from the left side plate 21 to form a horizontal mounting portion 3. Figure 8 As shown, a photovoltaic module 5 is mounted on a U-shaped gutter, and then a locking member is used to lock the mounting portion of the photovoltaic module 5 to the mounting portion 3 of the U-shaped gutter, achieving a secure connection between the two. In addition, the outer end of the mounting portion 3 is further bent downward to form a bent portion 4. When the U-shaped gutter is mounted on a supporting structure, this bent portion 4 can act as a limiter to prevent the gutter from unnecessary displacement or slipping during use, thereby ensuring a stable and safe installation.

[0032] The U-shaped drainage trough of this utility model is designed with a reinforcing rib structure on each plate surface. The details are as follows:

[0033] Regarding the structural reinforcement of the side panel 2, as Figures 4 to 7 As shown, the side wall of each side plate 2 bulges outward to form a wave-shaped reinforcement rib 23 extending along the length direction of the side plate 2. These reinforcement ribs enhance the structural strength of the gutter, so that even when the wall thickness is reduced, the gutter can still maintain excellent stability and durability.

[0034] In this embodiment, the wave-shaped reinforcement ribs 23 are of a uniform wave structure. This design makes the distribution of the reinforcement ribs more uniform and the force more reasonable. Figure 5 The wavy reinforcement ribs 23 are composed of several inclined reinforcement ribs 231 smoothly connected end to end. The angle δ between two adjacent inclined reinforcement ribs 231 is 90°, which further enhances the overall rigidity of the drainage trough. This angle not only ensures the reinforcement effect of the reinforcement ribs, but also avoids the stress concentration problem caused by excessive angles.

[0035] In this solution, the width W2 of the wavy reinforcement rib 23 can be adaptively selected according to product specifications, customer needs, etc. While ensuring the reinforcement effect of the reinforcement rib, the width W2 of the wavy reinforcement rib 23 can be reduced as much as possible, thereby reducing material costs. Figure 5 , this case is not limited.

[0036] In order to further enhance the structural strength of the side panel 2, this solution also adds horizontal reinforcement ribs 24 on the side panel 2. Figures 3 to 7 As shown, the side wall of each side panel 2 protrudes outward, forming horizontal reinforcing ribs 24 extending along its length. The number of these horizontal reinforcing ribs 24 can be flexibly set according to actual needs. At least one is set on each side panel 2. Of course, it can also be increased to multiple as needed, which is not limited in this case. In the preferred embodiment of this embodiment, the number of horizontal reinforcing ribs 24 on the side wall of each side panel 2 is two, as shown in the figure, namely the upper horizontal reinforcing rib 241 and the lower horizontal reinforcing rib 242. The upper horizontal reinforcing rib 241 is connected to the crest of the wavy reinforcing rib 23, and the lower horizontal reinforcing rib 242 is connected to the trough of the wavy reinforcing rib 23. Through the mutual support of the horizontal and wavy reinforcing ribs 23, a more stable three-dimensional reinforcement network is formed, which greatly improves the deformation resistance and service life of the U-shaped drainage trough.

[0037] Regarding the structural enhancement of the mounting portion 3, as shown in FIG. Figure 7 As shown, the middle portion of the mounting portion 3 is convex downward to form a rib 31. The rib 31 can enhance the overall strength and rigidity of the mounting portion 3, and also help to disperse stress, thereby improving its durability under heavy loads or complex stress environments.

[0038] Regarding the structural reinforcement of the bottom plate 1, as shown in 3 to Figure 7 As shown, the bottom of base plate 1 protrudes upward to form a ridge 11, with the top of ridge 11 parallel to the bottom of base plate 1. The design of ridge 11 not only increases the bending strength of base plate 1 but also effectively improves its ability to withstand impact forces and pressure distribution, ensuring the stability and safety of the structure. This structural design allows base plate 1 to better adapt to various application environments and extend its service life.

[0039] Due to the arrangement of the reinforcing rib structures on each panel, the thickness W1 of the panel can be reduced to a certain extent, reducing the material consumption without affecting its structural strength during use, thus ensuring its stability and durability in actual use. Furthermore, the reduction in material consumption can reduce material costs and save manufacturing costs.
