Description

Technical Field

[0001] This utility model belongs to the field of building-integrated photovoltaics (BIPV) technology, and particularly relates to a BIPV guide rail type water channel connection structure and water channel assembly. Background Technology

[0002] With the popularization of Building Integrated Photovoltaics (BIPV) technology, rooftop BIPV systems need to integrate multiple functions such as power generation, waterproofing, and structural support. Among these, the drainage channel, as a key component, guides rainwater and secures the photovoltaic panels; the reliability of its connection structure directly affects the overall system performance. Current mainstream drainage channel designs include "U," "W," and "M" shapes, with the "U" shape being widely adopted due to its large water flow capacity and low material cost. However, its connection method still has significant drawbacks. In rooftop BIPV systems, existing drainage channel connection structures suffer from complex installation, insufficient sealing, and poor compatibility with guide rail support modules. Traditional drainage channel splicing mainly relies on bolt fixing or welding, requiring additional sealant to fill the joints. This results in low installation efficiency, cumbersome operation, and a high risk of leakage due to construction errors or sealant aging. Furthermore, existing connectors are mostly designed for ordinary drainage channels and are not adapted to the guide rail structure and support modules of rail-type drainage channels. This leads to poor compatibility between the connection and the support module, potentially interfering with water flow or weakening wind uplift resistance, and also poses a risk of insufficient structural stability in long-term use. Existing technologies use plug-in connectors to connect water channels, simplifying the installation process. However, these designs do not consider the characteristics of guide rails in rail-type water channels, making them prone to leakage due to structural misalignment or loosening during long-term use. Furthermore, these connectors often employ single-layer splicing waterproofing, which poses a risk of leakage in extreme weather or after material aging, failing to meet the high requirements of long-term sealing for BIPV systems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a BIPV guide rail type water channel connection structure and water guiding assembly with good waterproof performance, good wind resistance, and simple installation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A BIPV guide rail type water channel connection structure includes a support groove and a limiting member. The limiting member is located on the inner bottom wall of the support groove and extends longitudinally along the support groove. The cross-section of the limiting member is "T"-shaped and is used to fit into the guide groove on the outer bottom wall of the water channel. The support groove has openings at both ends for inserting the ends of two water channels. The inner wall of the support groove can fit against the outer wall of the water channel. The openings on both sides of the support groove are provided with a first flat edge, and the openings on both sides of the water channel are provided with a second flat edge. The first flat edge can fit against the second flat edge. Locking members are provided on the first flat edge and the second flat edge to limit the relative displacement of the support groove and the water channel in the longitudinal direction.

[0006] In the above-mentioned BIPV guide rail type water channel connection structure, preferably, the locking element is a bolt hole and a bolt, and the bolt holes are spaced apart at corresponding positions on the first flat edge and the second flat edge.

[0007] Preferably, in the above-mentioned BIPV guide rail type water channel connection structure, the contact surface between the support channel and the water channel is covered with waterproof tape or a waterproof coating.

[0008] In the above-mentioned BIPV guide rail type water channel connection structure, preferably, the waterproof tape is butyl rubber waterproof tape or EPDM waterproof tape; the waterproof coating is silicone waterproof coating or silicone sealant waterproof coating.

[0009] Preferably, in the above-mentioned BIPV guide rail type water channel connection structure, the joint between the support channel and the front of the water channel is covered with waterproof aluminum foil or stainless steel tape in the installation state.

[0010] As a general technical concept, this utility model also provides a BIPV guide rail type water guiding assembly, including a water guiding channel, a support frame and a connecting structure. The connecting structure is the BIPV guide rail type water guiding channel connecting structure described above. Two adjacent water guiding channels are connected by one of the connecting structures. Multiple support frames are spaced apart in the water guiding channel for mounting two adjacent frames of two adjacent photovoltaic panels.

[0011] In the aforementioned BIPV guide rail type water guiding assembly, preferably, the bottom wall of the water guiding channel is bent inward, forming a longitudinally extending guide groove on the outer wall of the channel bottom, and a longitudinally extending guide rail on the inner wall of the channel bottom. The guide groove is nested with the limiting member, and the guide rail is nested with the bottom of the support frame.

[0012] Preferably, in the above-mentioned BIPV guide rail type water guide assembly, the support frame includes a vertical plate, a connecting plate, a bottom plate, a top plate, and a groove. The two vertical plates are arranged in parallel, and the connecting plate is perpendicularly connected to the vertical plates and forms an "H"-shaped bracket with the two vertical plates. The two bottom plates are respectively fixed to the bottom of the two vertical plates and are parallel to each other, so that the lower part of the "H"-shaped bracket with the bottom plate is nested with the guide rail. The two top plates are respectively fixed to the top of the two vertical plates and are parallel to each other. The top plates are used to mount the photovoltaic panel frame. The groove is fixed between the two top plates and is used to install the cover plate between the photovoltaic panels.

[0013] In the aforementioned BIPV guide rail type water guide assembly, preferably, the opening end of the groove is higher than the upper surface of the top plate, the edge of the top plate extends out of the outside of the vertical plate, and is used to adapt the photovoltaic panel frame and the top plate to be installed using a pressure block assembly. The end of the top plate connected to the groove extends out of the inner wall of the groove.

[0014] Preferably, in the above-mentioned BIPV guide rail type water guiding assembly, the bottom of the water guiding channel is provided with a plurality of non-drilling type locking parts at intervals along the longitudinal direction of the channel body for locking and fixing the support frame.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) To address the problems of leakage, insufficient wind uplift resistance, and poor installation adaptability caused by structural misalignment in traditional plug-in connectors, and the tendency for leakage and weak wind uplift resistance in complex environments or long-term use of existing single-layer splicing, this invention proposes a BIPV guide rail type water channel connection structure. Through the structural sealing of the support groove and the water channel fitting together, and the synergistic effect of the embedded structure of the guide groove and the "T"-shaped limiting component, the probability of leakage at the water channel connection is significantly reduced, waterproof reliability is improved, and wind uplift resistance is enhanced. Compared with the existing technology that requires manual alignment and cannot flexibly adjust the spacing at the joint of the two water channels, resulting in low installation efficiency, this invention uses guide rail sliding positioning and locking components for quick locking, greatly simplifying the installation process and adapting to diverse water channel splicing needs.

[0017] (2) The BIPV guide rail type water channel connection structure of this utility model achieves automatic alignment of the water channel through the design of the “T” type limiting component in the support channel, and has bidirectional displacement restriction. It adds waterproof tape on the basis of mechanical structure sealing to form a multi-level waterproof system and improves long-term sealing reliability.

[0018] (3) The BIPV guide rail type water guiding assembly of this utility model includes a water guiding channel, a support frame, and a connecting structure. Two adjacent water guiding channels are connected by a connecting structure, and multiple support frames are spaced apart in the water guiding channel to support the adjacent frames of two adjacent photovoltaic panels. This utility model simplifies installation, improves sealing, and ensures compatibility with the water guiding channel by optimizing the design and installation method of the connecting structure, thereby enhancing the reliability of the water guiding assembly and reducing maintenance costs. At the same time, it enhances the long-term waterproofing and structural stability of the water guiding assembly in complex environments, meeting the high requirements of BIPV systems. Meanwhile, the use of support frames independent of the water guiding channel to support the photovoltaic panels not only maintains the advantages of the "U"-shaped water guiding channel structure, such as simplicity, ease of processing, low material consumption, and large water guiding capacity, but also makes the processing of the water guiding channel and support frame simpler and more flexible.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This utility model discloses a BIPV guide rail type water channel connection structure, such as Figure 1 and Figure 2As shown in the figure, it includes a support groove 1 and a limiting member 2. The limiting member 2 is located on the inner bottom wall of the support groove 1 and extends longitudinally along the support groove 1. The cross-section of the limiting member 2 is "T"-shaped and is used to fit with the guiding groove 31 on the outer bottom wall of the water guiding groove 3. Both ends of the support groove 1 are open for inserting the ends of two water guiding grooves 3. The inner wall of the support groove 1 can be fitted with the outer wall of the water guiding groove 3. First flat edges 11 are provided at both open sides of the support groove 1, and second flat edges 32 are provided at both open sides of the water guiding groove 3. The first flat edges 11 can be fitted with the second flat edges 32. Locking members are provided on the first flat edges 11 and the second flat edges 32 for restricting the relative displacement in the longitudinal direction between the support groove 1 and the water guiding groove 3.

[0028] As Figure 3 and Figure 4 shown in the figure, a "T"-shaped limiting member is provided longitudinally in the middle of the support groove 1. More specifically, it is a limiting structure that combines a "Ji" shape and a "T" shape. This limiting member 2 can be closely fitted with the guiding groove 31 on the outer bottom wall of the water guiding groove 3. The cross-section of the guiding groove 31 is also "T"-shaped. When the water guiding grooves 3 are combined with the connection structure, the end parts of two adjacent water guiding grooves 3 are respectively inserted into both ends of the support groove 1 through the guiding groove 31 and the limiting member 2 in a nested manner. Thus, the left-right displacement after the connection of the water guiding grooves 3 can be restricted, avoiding the misalignment of the connection of the two water guiding grooves 3 and reducing the installation error. The horizontal part of the "T"-shaped limiting member is fitted in the "T"-shaped horizontal structure of the guiding groove 31, which can restrict the up-down displacement and enhance the wind uplift resistance performance; the longitudinal part of the "T"-shaped limiting member has a certain width and is embedded in the "T"-shaped longitudinal structure of the guiding groove 31 to further restrict the left-right offset of the water guiding groove 3 and ensure the connection stability.

[0029] When connecting the water guiding groove 3 with the connection structure of this embodiment, multi-level waterproofing can be formed at the splicing gap: the first level is the sealed waterproofing of the fitting structure between the support groove 1 and the water guiding groove 3, and the second level is the embedded waterproofing of the guiding groove 31 at the bottom of the water guiding groove 3 and the longitudinal structure of the "T"-shaped limiting member, effectively preventing rainwater leakage. When the BIPV guide rail type water guiding groove connection structure of this embodiment is used to connect the water guiding groove 3, the limiting member 2 in the support groove 1 can be used as a guide rail to slide and adjust the relative position in the longitudinal direction between the water guiding groove 3 and the support groove 1, and the position is locked by the locking members on both side flat edges, adapting to the requirements of different installation spacings, achieving multi-point fixation of the overall structure, and preventing water leakage caused by the longitudinal displacement of the connection structure.

[0030] In this embodiment, the locking members are bolt holes 12 and bolts. The bolt holes 12 are arranged at corresponding positions on the first flat edge 11 and the second flat edge 32 at intervals. When fixing, only need to adjust the relative position of the water guiding groove 3 in the support groove 1, align the bolt holes 12 on the first flat edge 11 and the second flat edge 32, and fix them with the matching bolts. Of course, in other embodiments, the support groove 1 can also be fixed with the water guiding groove 3 by using groove clamping.

[0031] In this embodiment, when the BIPV guide rail type water channel connection structure is assembled with the water channel 3, waterproof tape is applied between the contact surfaces of the support groove 1 and the water channel 3. An additional layer of waterproof tape, made of butyl rubber or EPDM (ethylene propylene rubber), is added at the joint between the water channel 3 and the support groove 1, and is adhered to the contact surfaces of the support groove 1 and the water channel 3. This waterproof tape serves as a third level of waterproofing, forming a triple protection system together with the original structural sealing (first level) and embedded waterproofing (second level), further preventing rainwater penetration.

[0032] Of course, in other embodiments, a waterproof coating, such as a silicone waterproof coating or a silicone sealant waterproof coating, can be added to the joint between the water guide channel 3 and the support channel 1. Butyl rubber waterproof tape and EPDM waterproof tape are both commercially available. The silicone waterproof coating can be obtained by applying commercially available silicone waterproof coating using conventional methods, and the silicone sealant waterproof coating can be obtained by applying commercially available silicone sealant waterproof coating using conventional methods.

[0033] In this embodiment, when the BIPV guide rail type water channel connection structure is assembled with the water channel 3, waterproof aluminum foil or stainless steel tape is attached to the front joint of the support groove 1 and the water channel 3, which further upgrades the waterproof effect on the basis of the aforementioned three-level waterproofing.

[0034] like Figure 2 As shown, the connecting structure adopts an integrated molding structure, which is long and narrow, and its length is adapted to the standard water guide channel 3. Bolt holes 12 are reserved on the flat edges at both ends for mating with the bolt holes 12 on the flat edges of the water guide channel 3. The opening of the support groove 1 is flared to facilitate the sliding of the water guide channel 3 into the guide rail.

[0035] like Figure 4 As shown, specifically, in this embodiment, when installing the water guide channel 3 connection structure, the water guide channel 3 is nested into both ends of the support groove 1 along the limiting member 2. The water guide channel 3 can slide within the support groove 1 using the limiting member 2 as a guide rail, thereby achieving automatic alignment and positioning of adjacent water guide channels 3. Waterproof tape or waterproof coating is pre-applied to the surface of the limiting member 2. When the water guide channel 3 slides in along the limiting member 2, it automatically presses the tape or coating, requiring no additional operation. The width of the waterproof tape covers both sides of the splicing gap and extends 2cm-10cm to ensure complete sealing. After the sliding water guide channel 3 is adjusted to the target spacing, the position can be locked by adjusting the bolts to adapt to different installation spacing requirements. In addition, after installation and fixing, waterproof aluminum foil or stainless steel tape is applied around the front connection gap to ensure better waterproofing effect. Furthermore, after the connection structure and water guide channel 3 are combined and installed at a certain tilt angle, under the action of gravity, water accumulation and leakage can be avoided, achieving multi-level waterproofing. This solution requires no welding or application of sealant throughout the entire process; only manual snap-fit ​​and bolt tightening are required, making installation and disassembly convenient. The modular design allows for batch pre-assembly, reducing construction difficulty and adapting to the splicing of different specifications of guide rail-type water channels.

[0036] Example 2

[0037] This utility model discloses a BIPV guide rail type water guiding assembly, such as Figure 5 As shown, it includes a water guide channel 3, a support frame 4, and a connecting structure. The connecting structure is the BIPV guide rail type water guide channel connecting structure of Embodiment 1. Two adjacent water guide channels 3 are connected by a connecting structure. Multiple support frames 4 are spaced apart in the water guide channel 3 for mounting two adjacent frames of two adjacent photovoltaic panels.

[0038] The BIPV guide rail water guide assembly of this embodiment adopts the connection structure of embodiment 1 to connect the water guide channel 3, achieving multiple waterproof effects. At the same time, it uses a support frame 4 independent of the water guide channel 3 to support the photovoltaic panel. This not only maintains the advantages of the "U"-shaped water guide channel structure, such as simplicity, ease of processing, low material consumption, and large water guiding capacity, but also makes the processing of the water guide channel 3 and the support frame 4 simpler and more flexible.

[0039] In this embodiment, the bottom wall of the water guide channel 3 is bent inward, forming a longitudinally extending guide channel 31 on the outer wall of the channel bottom and a longitudinally extending guide rail on the inner wall of the channel bottom. The guide channel 31 is nested with the limiting member 2, and the guide rail is nested with the bottom of the support frame 4. The cross-sections of both the guide rail and the guide channel 31 are "T" shaped. The water guide channel 3 with the bent structure has better mechanical strength than the bottom horizontal water guide channel. Furthermore, the nested cooperation between the guide rail and the support frame 4, and the nested cooperation between the guide channel 31 and the limiting member 2 in the connecting structure, saves space while fully utilizing the connecting function.

[0040] In this embodiment, the support frame 4 includes a vertical plate 41, a connecting plate 42, a bottom plate 43, a top plate 44, and a groove 45. The two vertical plates 41 are arranged in parallel, and the connecting plate 42 is vertically connected to the vertical plates 41 and forms an "H"-shaped bracket with the two vertical plates 41. The two bottom plates 43 are respectively fixed to the bottom of the two vertical plates 41 and are parallel to each other, so that the lower part of the "H"-shaped bracket with the bottom plate 43 is nested with the guide rail. The two top plates 44 are respectively fixed to the top of the two vertical plates 41 and are parallel to each other. The top plates 44 are used to mount the photovoltaic panel frame. The groove 45 is fixed between the two top plates 44 and is used to install the cover plate between the photovoltaic panels.

[0041] In this embodiment, the lower part of the "H"-shaped bracket and the base plate 43 are nested with the guide rail. When installing the support frame 4, simply nest the support frame 4 into the water channel 3 from one end of the guide rail. It can slide and adjust to any position along the guide rail, making installation and disassembly very convenient. Since the base plate 43 is embedded into the waist side of the "T"-shaped guide rail from both sides, the guide rail holds the support frame 4 in the vertical direction, making the connection between the two very strong in the vertical direction. Therefore, using this guide rail with the support frame 4 to install photovoltaic panel modules has strong wind resistance. The "H"-shaped bracket structure formed by the vertical plate 41 and the connecting plate 42 is relatively stable, and the two base plates 43 at the bottom further improve the stability of the support frame 4. The groove 45 and the top plate 44 fixed to the top of the "H"-shaped bracket can further enhance the overall mechanical strength and structural stability of the support frame 4. The groove 45 at the top of the support frame 4 is used to install the cover plate between the photovoltaic panel frames to reduce water entering the water channel 3 between the photovoltaic panels, reduce the water drainage pressure, and is more conducive to waterproofing.

[0042] In this embodiment, the opening end of the groove 45 is higher than the upper surface of the top plate 44, which is used to position and limit the relative position of the photovoltaic panel frame and the top plate 44 in the horizontal plane, and can quickly and accurately reserve the installation position of the cover plate; the edge of the top plate 44 extends out of the outside of the vertical plate 41, which is used to adapt the photovoltaic panel frame and the top plate 44 to be installed by the pressure block assembly, so as to diversify the installation method; the end of the top plate 44 connected to the groove 45 extends out of the inner wall of the groove 45, which is used to support the cover plate from the vertical direction.

[0043] In this embodiment, the bottom of the water guide channel 3 is provided with multiple non-drilling type locking components, such as adhesive locking components, at intervals along the longitudinal direction of the channel body. These components are used to lock and fix the support frame 4, and will not introduce the risk of water leakage due to drilling.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
