Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic buildings, in particular to a BIPV waterproof guide rail connector. Background Art

[0002] The BIPV (Building Integrated Photovoltaic) waterproof rail market is experiencing steady growth and holds promising prospects. This technology utilizes an innovative longitudinal W-shaped waterproof rail, longitudinal cover plate, and transverse U-shaped gutter design to effectively direct rainwater into the drainage system, eliminating the need for secondary roof waterproofing and achieving a perfect combination of aesthetics and functionality. BIPV waterproof rails offer flexible installation and a wide range of applications. Driven by global renewable energy policies and technological advancements, the market is expected to continue to grow.

[0003] The mainstream waterproof rails on the market currently use a non-porous design with a concave groove at the bottom. This design is highly durable and can effectively isolate the water-facing surface, preventing water leakage. However, due to factors such as construction technology and design flaws, BIPV waterproof rails still have leakage issues. Analysis of leakage in completed BIPV waterproof rails found that seamless splicing is difficult to achieve in practice, and gaps are easily left. On rainy days, rainwater will seep through these gaps. Although existing connectors can prevent lateral water seepage, under the impact of heavy rain, leakage in the vertical gaps remains a prominent problem. The infiltrating rainwater will flow into the concave groove, and because the concave groove is connected to the interior, it may cause leakage.

[0004] Based on this, in order to further improve the waterproof performance of the guide rail connection, we propose a BIPV waterproof guide rail connector. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 This is an embodiment of the present invention, which discloses a BIPV waterproof guide rail connector. The connector is connected between the bottoms of the two guide rail members 1 at the junction, and is used to solve the problem of water leakage at the junction of the existing waterproof guide rails. Of course, the structure of the guide rail member 1 is a prior art and will not be described in detail here. Specifically, the connector includes a shell 2; the shell 2 and the two guide rail members 1 are fixed by a locking structure 3, wherein a positioning structure 4 is further provided on the inner side of the shell 2, and the positioning structure 4 is movably connected to the guide rail members 1 on both sides to keep the axes of the two guide rail members 1 connected to each other;

[0023] The housing 2 is formed with bending portions 21 on both sides thereof to fit the two sides of the guide rail member 1 . By designing two bending portions 21 , maximum fit to the outer shape of the guide rail member 1 can be achieved to optimize the waterproof effect.

[0024] In some embodiments, the locking structure 3 of the present invention includes a slider 31 sliding in the concave groove 11 at the bottom of the guide rail member 1, and a through hole 22 is opened on the end face of the shell 2. A fastener connecting the slider 31 is provided in the through hole 22, and the fastener at least partially covers the through hole 22.

[0025] Specifically, the slider 31 in this embodiment is a rectangular nut, and the concave groove 11 is a T-slot. Specifically, in this embodiment, the upper end width of the concave groove 11 is greater than the width of the opening side to form a T-slot structure. Of course, those skilled in the art know that the width of the slider 31 is greater than the width of the opening of the concave groove 11, so that the slider 31 can slide stably inside the concave groove 11.

[0026] In addition, the fasteners in this embodiment include bolts and gaskets. The bolts pass through the gaskets and are threadedly connected to the slider 31. The gaskets cover the outside of the through holes 22. In further embodiments, the gaskets may include stainless steel gaskets and rubber gaskets arranged on both sides of the stainless steel gaskets. The diameter of the stainless steel gaskets should be larger than the through holes 22 to ensure that they are stably stressed. The rubber gaskets are designed to ensure a waterproof effect.

[0027] In some embodiments, the positioning structure 4 in this embodiment is a T-shaped block formed in the middle of the upper end of the shell 2, and the two ends of the T-shaped block are respectively inserted into the concave grooves 11 of the two guide rail parts 1, and the T-shaped block is tightly matched with the inner wall of the concave groove to improve the waterproof ability. During assembly, the concave grooves 11 at both ends of the guide rail part 1 are aligned with the T-shaped block and inserted. After the positioning is completed, the fastener locking slider 31 can be used to complete the connection and fixation of the guide rail part 1 and the shell 2.

[0028] In order to further improve the waterproof effect, in this embodiment, the connection points of the two guide rail members 1 are separated by a predetermined distance to form a glue area 5, and a waterproof glue layer is provided at the junction between the end of the guide rail member 1 and the upper surface of the shell 2. The waterproof glue layer is formed by solidifying the coated waterproof glue. That is to say, in this embodiment, a certain gap is separated between the ends of the two guide rail members 1 for brushing glue between the guide rail member 1 and the shell 2. This can further optimize the connection sealing of the guide rail member 1, thereby improving the waterproof effect.

[0029] In summary, the present invention designs a connector for the W-shaped waterproof guide rail with a non-porous design, so as to improve the waterproof ability of the connection between the two guide rail parts 1. Specifically, the slider 31 is passed through the concave groove 11 at the bottom of the guide rail part 1, and the shell 2 is provided with two through holes 22, which are used to be locked by fasteners, so that the shell 2 and the two guide rail parts 1 can be connected and fixed to ensure a firm fixation, and the positioning structure 4 is plugged and pressed with the concave groove 11 at the bottom of the guide rail part 1 to achieve a seamless connection, which can simultaneously meet the non-porous design of the guide rail part 1 and the firm installation with the connector, so as to better prevent the leakage of water in the guide rail part 1.
