Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic systems, in particular to a photovoltaic component full-roof waterproof system. Background Art
[0002] At present, most of the waterproof brackets for photovoltaic modules on sloping roofs in the market use M-type gutters. M-type gutters are usually set under two adjacent photovoltaic modules in the horizontal direction and extend diagonally downward from the ridge in the longitudinal direction. However, they are exposed at the ridge and cannot be completely waterproof. However, rainwater will flow from the ridge to the roof. If no gutters are installed and only glue is used to seal the edges, the glue will easily crack and age with exposure to sunlight and corrosion by rain, resulting in the risk of leakage at the ridge, which will cause the photovoltaic modules to not be completely waterproof during their service life. In addition, the cost of the M-type gutters is relatively high, and the construction and installation methods are relatively complicated. Utility Model Content
[0003] The purpose to be achieved by the utility model is to provide a photovoltaic module full roof waterproof system to solve the problem of photovoltaic module roof leakage.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a photovoltaic module full roof waterproofing system, the whole roof includes two sloping roofs and the tops of the two sloping roofs are connected to form a ridge, photovoltaic modules are installed on the two sloping roofs, the photovoltaic module full roof waterproofing system includes a ridge water guide groove, a transverse water guide groove, a longitudinal water guide groove and a main water guide groove, the ridge water guide groove is arranged above the ridge, the transverse water guide groove is arranged below the adjacent parts of the photovoltaic modules on the two sides adjacent to each other in the longitudinal direction, the longitudinal water guide groove is arranged below the adjacent parts of the photovoltaic modules on the two sides adjacent to each other in the transverse direction, and the main water guide groove is arranged obliquely below the photovoltaic modules on the sloping roofs on both sides; the transverse water guide groove and the ridge water guide groove are connected to the longitudinal water guide groove, and the water in the transverse water guide groove and the ridge water guide groove flows into the longitudinal water guide groove; the oblique downward end of the longitudinal water guide groove is connected to the main water guide groove, and the water in the longitudinal water guide groove flows into the main water guide groove.
[0005] After adopting the above technical scheme, the utility model has the following advantages: the combined design of the ridge water guide groove, the horizontal water guide groove, the longitudinal water guide groove and the main water guide groove can achieve all-round waterproof coverage of the entire photovoltaic module roof. The ridge is the part where the sloping roofs on both sides are connected, and it is also the high point of the rainwater flow. The ridge water guide groove is located above the ridge and plays a role in guiding the flow of rainwater. The ridge water guide groove receives rainwater from the sloping roofs on both sides and guides the rainwater to flow downward, thereby effectively avoiding the accumulation of rainwater at the ridge and preventing leakage caused by water accumulation. Problems occur; the ridge gutter connects the longitudinal gutter and the transverse gutter, the longitudinal gutter is connected to the main gutter, and the troughs cooperate with each other to effectively guide rainwater flowing from all directions to flow smoothly to the main gutter, reducing water accumulation and leakage on the roof, thereby effectively extending the service life of photovoltaic modules. This structure can not only protect the photovoltaic modules themselves, but also extend the service life of the building, avoid problems such as wood rot and metal rust caused by water infiltration into the house, and the manufacturing cost and maintenance cost are relatively low.
[0006] Furthermore, several photovoltaic modules on the sloping roof are arranged in a rectangular array, or the length directions of several photovoltaic modules on the sloping roof are consistent with the longitudinal direction, so that the overall arrangement and combination is a vertically mounted module; or the length directions of several photovoltaic modules on the upper side of the sloping roof are consistent with the transverse direction, so that the arrangement and combination is an upper horizontally mounted module, and the length directions of several photovoltaic modules on the lower side of the sloping roof are consistent with the longitudinal direction, so that the arrangement and combination is a lower vertically mounted module.
[0007] By adopting the above-mentioned technical solution, the photovoltaic modules are neatly arranged on the sloping roof to form vertically mounted modules or upper horizontally mounted modules, so that the overall structure of the photovoltaic modules is more unified and compact, thereby better controlling the arrangement of the gutters on the roof, improving the waterproof performance of the roof and the aesthetics of the roof.
[0008] Furthermore, a transverse water guide groove is provided below the connecting position of the upper horizontally mounted component and the lower vertically mounted component, and a small water guide groove of the horizontally mounted component is provided below the adjacent parts of the photovoltaic components on both sides of the upper horizontally mounted component, and the flowing water in the small water guide groove of the horizontally mounted component flows into the transverse water guide groove; and / or, a longitudinal water guide groove is provided below the adjacent parts of the photovoltaic components on both sides of the lower vertically mounted component, passes upwardly under the upper horizontally mounted component and the upper end is connected to the ridge water guide groove.
[0009] By adopting the above-mentioned technical solution, a complete water flow guiding system is formed by combining the upper horizontal mounting components with the lower vertical mounting components, as well as the design of the horizontal water guide groove and the longitudinal water guide groove. Such a water flow guiding system can cover all directions of the roof, preventing rainwater from being retained or accumulated anywhere, thereby ensuring the waterproof performance of the entire roof while reducing the risk of leakage.
[0010] Furthermore, a drainage hole is provided at the intersection of the transverse water channel, the ridge water channel and the longitudinal water channel; and / or, the upper end of the small water channel of the horizontally mounted component is fixed to the ridge water channel by self-tapping screws, and the lower end is fixed to the transverse water channel by self-tapping screws.
[0011] By adopting the above-mentioned technical solution, drainage holes are set at the intersection of the horizontal water gutter and the ridge water gutter with the longitudinal water gutter, so as to effectively drain water and avoid problems such as water accumulation or leakage. Self-tapping screws are used to fix the upper end of the small water gutter of the horizontally mounted component to the ridge water gutter and the lower end to the horizontal water gutter, so as to ensure that the water gutter is firmly fixed to increase the stability of the system. The self-tapping screws have a self-tapping function and can directly penetrate and anchor in the substrate without pre-drilling, so the installation process is simpler and faster.
[0012] Furthermore, the photovoltaic assembly is installed on a photovoltaic bracket, and the photovoltaic bracket includes a plurality of longitudinal beams and a plurality of cross beams vertically and crosswise arranged above the plurality of longitudinal beams, and the photovoltaic assembly is fixed on the cross beams.
[0013] Using the aforementioned technical solution, photovoltaic modules are installed on photovoltaic brackets. By setting longitudinal beams and transverse beams, a stable supporting structure is formed, which helps to maintain the stability and integrity of the overall structure of the photovoltaic modules. The photovoltaic brackets suspend the photovoltaic modules on the roof. The photovoltaic modules are not in direct contact with the sloping roof. This separation design reduces the contact friction between the photovoltaic modules and the sloping roof, thereby reducing the wear and damage to the sloping roof.
[0014] Furthermore, the ridge gutter includes an inverted V-portion and an L-shaped second water retaining portion connected to the lower ends of both sides of the inverted V-portion. The both sides of the inverted V-portion are arranged on the longitudinal beam and fixed to the longitudinal beam by self-tapping screws.
[0015] By adopting the above-mentioned technical solution, the design of the ridge gutter can avoid water leakage at the ridge, so that the water flow can be smoothly collected and guided to the designated position, effectively avoiding the problem of water retention and accumulation on the roof, and improving the drainage efficiency of the roof. The inverted V part is usually located at the ridge, and its design is intended to collect rainwater on the roof and guide it into the longitudinal gutter. When rainwater flows through the roof, the V-shaped design of the inverted V part will cause the water to flow along the V-shaped part to the longitudinal gutter, ensuring that the water flow is effectively collected and guided; the L-shaped second water retaining part is located below the photovoltaic module, and is usually an extended part, and its edge is designed to block rainwater from flowing into the area below the photovoltaic module. By designing the L-shaped water retaining part to extend and be located below the photovoltaic module, such a design ensures that rainwater is effectively guided to the inverted V part and the longitudinal gutter, while also preventing water from entering the space below the photovoltaic module.
[0016] Furthermore, the longitudinal water guide groove includes a first U-shaped portion and wing portions arranged on both sides of the mouth of the first U-shaped portion, the wing portions are connected with first fastening bolts, and the first fastening bolts are connected to the cross beam, thereby fixing the longitudinal water guide groove and the cross beam.
[0017] By adopting the above-mentioned technical solution, the design of the first U-shaped part makes the longitudinal water guide groove have a larger capacity, which can collect and store a large amount of water flow and ensure the effectiveness of drainage. The side wing parts are located on both sides of the mouth of the first U-shaped part, and the two sides are connected with the first fastening bolts. The first fastening bolts are connected to the cross beam, and the longitudinal water guide groove is fixed on the cross beam of the photovoltaic bracket, thereby ensuring the stable installation and firm fixation of the longitudinal water guide groove.
[0018] Furthermore, the transverse water guide groove includes a second U-shaped portion and a first water retaining portion provided at the longitudinal lower side of the mouth of the second U-shaped portion and extending longitudinally upward, and the bottom wall of the second U-shaped portion is fixed to the longitudinal beam by self-tapping screws.
[0019] By adopting the above-mentioned technical solution, the transverse water guide groove includes a second U-shaped portion and a first water retaining portion arranged on the longitudinal lower side of the mouth of the second U-shaped portion and extending to the longitudinal upper side. Such a design enables the transverse water guide groove to have the advantages of guiding water flow, preventing overflow, improving engineering efficiency, enhancing structural stability and wide applicability. In addition, the bottom wall of the second U-shaped portion is fixed to the longitudinal beam by using self-tapping screws, thereby enhancing the overall stability of the transverse water guide groove.
[0020] Furthermore, the main water tank has a longitudinal lower water retaining edge and a longitudinal upper water retaining edge, and the longitudinal lower water retaining edge is higher than the longitudinal upper water retaining edge.
[0021] By adopting the above-mentioned technical solution, the main gutter is used to collect water flowing out of the ridge gutter, the transverse gutter, and the longitudinal gutter and guide the water to the designated location, so as to avoid water retention or accumulation on the roof, thereby improving the drainage efficiency of the roof. The height of the longitudinal lower water retaining edge is better than that of the longitudinal upper water retaining edge, which helps to effectively guide the water flow into the main gutter, reduces the possibility of water overflow, and enhances the ability to concentrate and guide the water flow.
[0022] Furthermore, the main water sink is fixed to a water sink bracket, and the water sink bracket is provided with a supporting groove for supporting the main water sink and a fixed edge connected to the longitudinal upper side wall of the supporting groove, the longitudinal upper side wall of the supporting groove abuts against the lower end surface of the longitudinal beam and the fixed edge fits the upper surface of the lower end portion of the longitudinal beam, and the fixed edge is fixed to the lower end portion of the longitudinal beam by a second fastening bolt.
[0023] By adopting the above-mentioned technical solution, the sink bracket provides a stable supporting structure through the design of supporting grooves and fixed edges, ensuring that the main sink can be firmly fixed on the lower side of the sloping roof and is not easy to loosen or shift. The stable support of the sink bracket ensures the accurate position of the main sink, prevents leakage caused by looseness or instability of the sink, and improves the waterproof performance of the entire system. The sink bracket is fixed to the longitudinal beam by a second fastening bolt, which ensures the stability of the sink under severe weather conditions such as wind and rain, and enhances the durability and reliability of the system.

[0044] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0045] like Figures 1 to 16 As shown, the utility model provides a photovoltaic component full roof waterproofing system, the full roof includes two side sloping roofs 1 and the tops of the two side sloping roofs 1 are connected to form a ridge, photovoltaic components 6 are installed on the two side sloping roofs 1, and the photovoltaic component 6 full roof waterproofing system includes a ridge water guide 21, a transverse water guide 22, a longitudinal water guide 23 and a main water guide 24, the ridge water guide 21 is arranged above the ridge, the transverse water guide 22 is arranged below the adjacent parts of the photovoltaic components 6 on the two sides adjacent to each other in the longitudinal direction, the longitudinal water guide 23 is arranged below the adjacent parts of the photovoltaic components 6 on the two sides adjacent to each other in the transverse direction, and the main water guide 24 is arranged obliquely below the photovoltaic components 6 on the two side sloping roofs 1; the transverse water guide 22 and the ridge water guide 21 are connected to the longitudinal water guide 23, and the water in the transverse water guide 22 and the ridge water guide 21 flows into the longitudinal water guide 23; the oblique downward end of the longitudinal water guide 23 is connected to the main water guide 24, and the water in the longitudinal water guide 23 flows into the main water guide 24. Through the combined design of the ridge gutter 21, the transverse gutter 22, the longitudinal gutter 23 and the main gutter 24, the entire photovoltaic module 6 roof can be fully waterproofed. The ridge is the part where the two sloping roofs 1 meet and is also the high point of the rainwater flow. The ridge gutter 21 is located above the ridge and plays a role in guiding the flow of rainwater. The ridge gutter 21 receives rainwater from the two sloping roofs 1 and guides the rainwater to flow downward, thereby effectively avoiding the accumulation of rainwater at the ridge and preventing leakage caused by water accumulation. The groove 21 connects the longitudinal water guide groove 23 and the transverse water guide groove 22. The longitudinal water guide groove 23 is connected to the main water groove 24. The grooves cooperate with each other to effectively guide rainwater flowing from all directions to flow smoothly to the main water groove 24, reduce water accumulation and leakage on the roof, thereby effectively extending the service life of the photovoltaic module 6. This structure can not only protect the photovoltaic module 6 itself, but also extend the service life of the building, avoid problems such as wood rot and metal rust caused by water infiltration into the house, and the manufacturing cost and maintenance cost are relatively low.
[0046] In this embodiment, the photovoltaic module 6 is installed on the photovoltaic bracket 7, and the photovoltaic bracket 7 includes a plurality of longitudinal beams and a plurality of cross beams vertically cross-arranged above the plurality of longitudinal beams, and the photovoltaic module 6 is fixed on the cross beams. The photovoltaic module 6 is installed on the photovoltaic bracket 7, and a stable support structure is formed by the arrangement of the longitudinal beams and the cross beams, which helps to maintain the stability and integrity of the overall structure of the photovoltaic module 6. The photovoltaic bracket 7 hangs the photovoltaic module 6 on the roof, and the photovoltaic module 6 is not in direct contact with the sloping roof. This separation design reduces the contact friction between the photovoltaic module 6 and the sloping roof 1, thereby reducing the wear and damage to the sloping roof 1.
[0047] Usually, a single photovoltaic module 6 is a rectangular structure, so a plurality of photovoltaic modules 6 are arranged in a rectangular array on the sloping roof 1 .
[0048] like Figure 1 and Figure 2 As shown, the length directions of several photovoltaic modules 6 on the sloping roof 1 are consistent with the longitudinal direction, so that the overall arrangement and combination is a vertically mounted module.
[0049] like Figure 3 and Figure 4 As shown, if the length directions of several photovoltaic modules 6 on the upper side of the sloping roof 1 are consistent with the horizontal direction, they are arranged and combined into upper horizontal modules, and the length directions of several photovoltaic modules 6 on the lower side of the sloping roof 1 are consistent with the longitudinal direction, they are arranged and combined into lower vertical modules. By arranging the photovoltaic modules 6 neatly on the sloping roof 1, the overall structure of the photovoltaic modules 6 is more unified and compact, so that the arrangement of the gutters on the roof can be better controlled, thereby improving the waterproof performance of the roof and the aesthetics of the roof.
[0050] Specifically, a transverse water guide trough 22 is provided below the joint position of the upper horizontal assembly and the lower vertical assembly, and a small water guide trough 9 of the horizontal assembly is provided below the adjacent parts of the photovoltaic assemblies 6 on both sides of the upper horizontal assembly. The water in the small water guide trough 9 of the horizontal assembly flows into the transverse water guide trough 22, and in the lower vertical assembly, the longitudinal water guide 8 provided below the adjacent parts of the photovoltaic assemblies 6 on both sides of the horizontal assembly passes upward under the upper horizontal assembly and the upper end is connected to the ridge water guide trough 21. Through the combination of the upper horizontal assembly and the lower vertical assembly, as well as the design of the transverse water guide trough 22 and the longitudinal water guide trough 23, a complete water flow guiding system is formed. Such a water flow guiding system can cover all directions of the roof, prevent rainwater from being retained or accumulated anywhere, ensure the waterproof performance of the entire roof while reducing the risk of water leakage.
[0051] In this embodiment, a drainage hole 222 is provided at the intersection of the transverse water channel 22 and the ridge water channel 21 and the longitudinal water channel 23. By providing the drainage hole 222 at the intersection of the transverse water channel 22 and the ridge water channel 21 and the longitudinal water channel 23, water can be effectively drained to avoid water accumulation and leakage problems.
[0052] In the fully vertical structure, the photovoltaic components 6 are arranged along the vertical direction of the sloping roof 1, which means that the long side of the photovoltaic components 6 is parallel to the slope direction of the sloping roof 1. This arrangement is usually used in scenes with a larger slope or special requirements for the arrangement of the photovoltaic components 6. In the overall vertical structure, the photovoltaic components 6 are arranged along the vertical direction of the sloping roof 1. Therefore, the setting of the gutter is usually carried out along the vertical arrangement of the photovoltaic components 6. The ridge gutter 21 is located at the top of the ridge, which is used to collect rainwater flowing down from the top and then guide it into the main gutter 24. The longitudinal gutter 23 is set below the vertical arrangement of the photovoltaic components 6, which is used to collect rainwater flowing down from the photovoltaic components 6 and guide it into the main gutter 24.
[0053] It is understandable that in another embodiment, a horizontal and vertical mixed structure is adopted, in which the photovoltaic components 6 are arranged in both a horizontal and vertical manner to maximize the use of the available installation space and optimize the performance of the photovoltaic system. This layout is usually used in complex or limited site environments to achieve higher energy output and better system efficiency. In the horizontal and vertical mixed structure, the photovoltaic modules 6 are arranged both horizontally and vertically, which means that on the same sloping roof 1, a part of the photovoltaic modules 6 are arranged along the horizontal direction of the slope, while the other part is arranged along the vertical direction. This mixed layout is usually used to make full use of the available space and optimize the performance of the photovoltaic system, and is usually used in complex or limited site environments. The ridge gutter 21 is located at the top of the ridge, for collecting rainwater flowing down from the top and then guiding it into the main gutter 24. The transverse gutter 22 is arranged below the transversely arranged photovoltaic modules 6 to collect rainwater flowing down from these modules and guide it into the main gutter 24. The longitudinal gutter 23 is arranged below the longitudinally arranged photovoltaic modules 6 to collect rainwater flowing down from these modules and guide it into the main gutter 24.
[0054] However, no matter it is an integral vertical structure or a horizontal and vertical mixed structure, the layout of the gutter should be able to effectively collect rainwater and guide it into the main gutter 24 to ensure the drainage effect and waterproof performance of the roof.
[0055] In order to improve the overall stability of the equipment, the upper end of the small water tank 9 of the horizontally mounted component is fixed to the ridge water tank 21 with self-tapping screws 4, and the lower end is fixed to the transverse water tank 22 with self-tapping screws 4. The upper end of the small water tank 9 of the horizontally mounted component is fixed to the ridge water tank 21, and the lower end is fixed to the transverse water tank 22 with self-tapping screws 4, which ensures the firm fixation of the water tank and increases the stability of the system. The self-tapping screws 4 have a self-tapping function and can directly penetrate and anchor in the substrate without pre-drilling, so the installation process is simpler and faster.
[0056] In this embodiment, if Figure 5 and Figure 6 As shown, the longitudinal water guide groove 23 includes a first U-shaped portion 231 and side wings 232 arranged on both sides of the mouth of the first U-shaped portion 231, and the side wings 232 are connected with first fastening bolts 51, and the first fastening bolts 51 are connected with the cross beam, so as to fix the longitudinal water guide groove 23 with the cross beam. The design of the first U-shaped portion 231 enables the longitudinal water guide groove 23 to have a large capacity, which can collect and store a large amount of water flow and ensure the effectiveness of drainage. The side wings 232 are located on both sides of the mouth of the first U-shaped portion 231, and the two sides are connected with first fastening bolts 51, and the first fastening bolts 51 are connected with the cross beam. The longitudinal water guide groove 23 is fixed on the cross beam of the photovoltaic bracket 7, so as to ensure the stable installation and firm fixation of the longitudinal water guide groove 23.
[0057] In this embodiment, Figures 7 to 9 As shown, the transverse water guide groove 22 includes a second U-shaped portion 223 and a first water retaining portion 221 arranged at the longitudinal lower side of the mouth of the second U-shaped portion 223 and extending to the longitudinal upper side. The bottom wall of the second U-shaped portion 223 is fixed to the longitudinal beam by self-tapping screws 4. The transverse water guide groove 22 includes a second U-shaped portion 223 and a first water retaining portion 221 arranged at the longitudinal lower side of the mouth of the second U-shaped portion 223 and extending to the longitudinal upper side. It has the advantages of guiding water flow, preventing overflow, improving engineering efficiency, enhancing structural stability and wide applicability. Moreover, by using self-tapping screws 4 to fix the bottom wall of the second U-shaped portion 223 to the longitudinal beam, the overall stability of the transverse water guide groove 22 can be enhanced.
[0058] In this embodiment, if Figures 10 to 12 As shown, the ridge gutter 21 includes an inverted V-portion 212 and an L-shaped second water retaining portion 211 connected to the lower ends of the two side edges of the inverted V-portion 212. The two side edges of the inverted V-portion 212 are arranged on the longitudinal beam and fixed to the longitudinal beam with self-tapping screws 4. The design of the ridge gutter 21 can avoid water leakage on the ridge, so that the water flow can be smoothly collected and guided to the designated position, effectively avoiding the problem of water flow retention and accumulation on the roof, and improving the drainage efficiency of the roof. The inverted V-portion 212 is usually located at the ridge, and its design is intended to collect rainwater on the roof and guide it into the longitudinal gutter 8. When rainwater flows through the roof, the V-shaped design of the inverted V-portion 212 will cause the water to flow along the V-shaped portion to the longitudinal gutter 8, ensuring that the water flow is effectively collected and guided; the L-shaped second water retaining portion 211 is located below the photovoltaic component 6 and is usually an extended portion, whose edge is designed to block rainwater from flowing into the area below the photovoltaic component 6. By designing the L-shaped water retaining portion to extend and be located below the photovoltaic component 6, it ensures that rainwater is effectively guided to the inverted V-portion 212 and the longitudinal gutter 8, while preventing water from flowing into the space below.
[0059] In this embodiment, the main water trough 24 has a longitudinal lower water retaining edge 241 and a longitudinal upper water retaining edge 242, and the longitudinal lower water retaining edge 241 is higher than the longitudinal upper water retaining edge 242. The main water trough 24 is used to collect water flowing out of the ridge water guide trough 21, the transverse water guide trough 22, and the longitudinal water guide trough 23 and guide it to a designated position, so as to avoid water flow being retained and accumulated on the roof, thereby improving the drainage efficiency of the roof. The height of the longitudinal lower water retaining edge 241 is higher than that of the longitudinal upper water retaining edge 242, which helps to effectively guide the water flow to the inside of the main water trough 24, reduces the possibility of water flow overflow, and enhances the concentration and guiding ability of water flow.
[0060] Specifically, the main water tank 24 is fixed to the water tank bracket 3. The water tank bracket 3 is provided with a supporting groove 31 for supporting the main water tank 24 and a fixed edge 32 connected to the longitudinal upper side wall of the supporting groove 31. The longitudinal upper side wall of the supporting groove 31 abuts against the lower end surface of the longitudinal beam and the fixed edge 32 fits the upper surface of the lower end of the longitudinal beam. The fixed edge 32 is fixed to the lower end of the longitudinal beam by a second fastening bolt 52. The water tank bracket 3 provides a stable support structure through the design of the supporting groove 31 and the fixed edge 32, ensuring that the main water tank 24 can be firmly fixed on the lower side of the sloping roof 1. The stable support of the water tank bracket 3 ensures that the main water tank 24 is accurately positioned, preventing the water tank from leaking due to looseness or instability, and improving the waterproof performance of the entire system. The water tank bracket 3 is fixed to the longitudinal beam by the second fastening bolt 52, ensuring the stability of the water tank under severe weather conditions such as wind and rain, and enhancing the durability and reliability of the system.
[0061] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes.
