Description

Technical Field

[0002] In the existing system, the mainstream Building Integrated Photovoltaic (BIPV) approach is to use M-shaped gutters as drainage and load-bearing components for photovoltaic modules.

[0003] However, in the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0004] First, since the M-type gutter needs to directly bear the load of the photovoltaic module, it is necessary to select an M-type gutter of relatively large specifications and thickness, which makes the cost of the M-type gutter too high; second, it is necessary to lock the bolts of the pressure block from the side of the gutter to fix the photovoltaic module. The installation space is too small and it is not suitable for workers to use power tools to fix it, resulting in inconvenience in operation; third, it is necessary to use self-tapping screws to fix the M-type gutter on the purlin. Because many M-type gutter are currently made of high-strength steel, it takes a lot of time to drill holes, and it is also more troublesome to disassemble it during later operation and maintenance.

[0005] Therefore, it is necessary for those skilled in the art to provide a photovoltaic module waterproof device in a timely manner that has good waterproof effect, is easy to install and disassemble, and can reduce production costs. Utility Model Content

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0052] See also Figure 1 , Figure 2 and Figure 3 The photovoltaic module waterproof device provided in the embodiment of the present application includes a plurality of purlins 1 arranged along the transverse direction and a plurality of photovoltaic modules 2 arranged on the plurality of purlins 1. Transverse gaps 3 and longitudinal gaps 4 are arranged between the plurality of photovoltaic modules 2. The function of the transverse gaps 3 and longitudinal gaps 4 is to facilitate the discharge of rainwater.

[0053] Furthermore, the waterproof device of the photovoltaic module 2 also includes a transverse water-conducting structure 5, a longitudinal water-conducting structure 6, a converging water-discharging component 7 and a longitudinal drainage structure 8.

[0054] Of course, please refer to Figure 4 and Figure 5 The longitudinal drainage structure 8 may be a drainage groove structure, and the drainage groove structure may be a polygonal groove structure. Please refer to Figure 6 The transverse water guiding structure 5 and the longitudinal water guiding structure 6 have the same structure and can both be water guiding groove structures, and the water guiding groove structure can be a U-shaped groove structure.

[0055] Among them, the transverse water guiding structure 5 is arranged below the transverse gap 3, and the transverse water guiding structure 5 is used to guide the rainwater flowing down from the transverse gap 3 in the transverse direction. The longitudinal water guiding structure 6 is arranged below the longitudinal gap 4, and the longitudinal water guiding structure 6 is used to guide the rainwater flowing down from the longitudinal gap 4 in the longitudinal direction. The confluence water component 7 is arranged at the intersection of the transverse water guiding structure 5 and the longitudinal water guiding structure 6. The confluence water component 7 is used to fix the transverse water guiding structure 5 and the longitudinal water guiding structure 6 on the frame 21 of the corresponding photovoltaic component 2, and the confluence water component 7 is also used to collect the rainwater guided by the transverse water guiding structure 5 and the longitudinal water guiding structure 6. The longitudinal drainage structure 8 is arranged below the confluence water component 7 in the longitudinal direction, and the longitudinal drainage structure 8 is used to discharge the rainwater flowing down from the confluence water component 7.

[0056] It should be noted that the so-called horizontal and vertical directions are defined with reference to the plane where the photovoltaic module 2 is located, wherein the horizontal direction can be as follows: Figure 1 The X-axis direction is shown, and the longitudinal direction can be as follows Figure 1 The Y-axis direction is shown.

[0057] The rainwater on the entire photovoltaic assembly 2 is discharged in two parts, one part flows out along the slope of the photovoltaic assembly 2, and the other part is discharged through the waterproof combined structure of the transverse water guide structure 5, the longitudinal water guide structure 6, the converging water assembly 7 and the longitudinal drainage structure 8.

[0058] In this way, except for the rainwater flowing out along the slope of the photovoltaic module 2, the rest of the rainwater can be discharged through the waterproof combination structure of the transverse water guide structure 5, the longitudinal water guide structure 6, the converging water guide assembly 7 and the longitudinal drainage structure 8. Specifically, the rainwater flows into the transverse water guide structure 5 and the longitudinal water guide structure 6 through the transverse gap 3 and the longitudinal gap 4 between the photovoltaic modules 2, and the transverse water guide structure 5 and the longitudinal water guide structure 6 guide the rainwater to the converging water guide assembly 7 in the transverse and longitudinal directions respectively. Under the gathering effect of the converging water guide assembly 7, the rainwater enters the longitudinal drainage structure 8 and is finally discharged by the longitudinal drainage structure 8.

[0059] It can be understood that, compared with the traditional settings, the photovoltaic module waterproof device provided in the embodiment of the present application, on the one hand, adopts a waterproof combination structure of a horizontal water guide structure 5, a longitudinal water guide structure 6, a converging water assembly 7 and a longitudinal drainage structure 8, which not only has a good waterproof effect and ensures that there is no water leakage, but also is easy to disassemble and assemble, effectively improving the construction effect; on the other hand, the main body of the above-mentioned waterproof combination structure is fixed on the frame 21 of the photovoltaic module 2, and the photovoltaic module 2 is supported by the purlin 1, that is, the traditional problem of load-bearing by the water tank is transformed into load-bearing by the purlin 1, which can reduce the production requirements for the waterproof combination structure, thereby greatly reducing the production cost.

[0060] In addition, the above arrangement method optimizes the load-bearing structure based on the original photovoltaic modules 2 and purlins 1 without changing the original main structure of the sun room, which can also achieve the purpose of reducing costs and increasing efficiency to a certain extent.

[0061] In some embodiments, the confluence and drainage assembly 7 can be an assembly including a confluence and drainage structure 71 and a pressure block assembly 72, wherein the confluence and drainage structure 71 is connected to the transverse water guiding structure 5 and the longitudinal water guiding structure 6, and the pressure block assembly 72 is connected to the confluence and drainage structure 71 and the frame 21 of the corresponding photovoltaic assembly 2, and the pressure block assembly 72 is used to fix the confluence and drainage structure 71 and the transverse water guiding structure 5 or the longitudinal water guiding structure 6 to the frame 21 of the corresponding photovoltaic assembly 2.

[0062] That is, the pressing block assembly 72 is connected to the confluence and drainage structure 71 and the frame 21 of the corresponding photovoltaic assembly 2 to fix the confluence and drainage structure 71 and the transverse water guiding structure 5 or the longitudinal water guiding structure 6 to the frame 21 of the corresponding photovoltaic assembly 2 .

[0063] It is understandable that the block assembly 72 is provided in at least one direction in both the horizontal and vertical directions. For example, the block assembly 72 can be provided in the longitudinal direction, and the block assembly 72 can fix the confluence water structure 71 and the longitudinal water guide structure 6 to the frame 21 of the corresponding photovoltaic module 2. At the same time, the transverse water guide structure 5 is also pressed against the frame 21 of the corresponding photovoltaic module 2. In other words, as long as the block assembly 72 is provided in one of the horizontal and longitudinal directions, the water guide structure in the other direction is also pressed accordingly.

[0064] Of course, the pressing block assembly 72 may also be provided in both the transverse direction and the longitudinal direction.

[0065] Please also read Figure 7 , Figure 8 and Fig. 9 The pressing block assembly 72 includes two pressing blocks 721 , and the two pressing blocks 721 are respectively buckled and connected to the two sides of the transverse gap 3 or the longitudinal gap 4 .

[0066] Specifically, the converging and draining assembly 7 may include a converging and draining structure 71 and four pressing blocks 721. The four pressing blocks 721 are oppositely buckled and connected to the converging and draining structure 71 at two sides in the horizontal or vertical direction.

[0067] More specifically, for a confluence water-conducting structure 71 located at the intersection of two longitudinal water-conducting structures 6 and two transverse water-conducting structures 5, the two transverse water-conducting structures 5 are respectively embedded in the two ends of the confluence water-conducting structure 71 along the transverse direction, and the two longitudinal water-conducting structures 6 are respectively embedded in the two ends of the confluence water-conducting structure 71 along the longitudinal direction, wherein two pressing blocks 721 are snap-fitted and connected to one end of the confluence water-conducting structure 71 along the longitudinal direction, and the other two pressing blocks 721 are snap-fitted and connected to the other end of the confluence water-conducting structure 71 along the longitudinal direction, so that the two longitudinal water-conducting structures 6, the two transverse water-conducting structures 5 and the confluence water-conducting structure 71 can be fixed on the frame 21 of the corresponding photovoltaic module 2.

[0068] In order to facilitate the snap-fit ​​connection between the pressing block 721 and the confluence and drainage structure 71, any pressing block 721 is provided with a snap-fit ​​hole 7211, and the confluence and drainage structure 71 is provided with a snap-fit ​​protrusion 711, and the snap-fit ​​protrusion 711 is snap-fitted with the snap-fit ​​hole 7211 to connect the confluence and drainage structure 71 and the pressing block 721.

[0069] In this embodiment, the outer wall of the converging drainage structure 71 may be provided with a plurality of triangular snap-fitting protrusions 711 , and correspondingly, the pressing block 721 is provided with a plurality of snap-fitting holes 7211 , and the snap-fitting holes 7211 and the snap-fitting protrusions 711 are snap-fitted and connected one by one.

[0070] It should be emphasized that the present embodiment adopts the method of buckling the pressing block 721 on the converging drainage structure 71 to avoid installation by gluing or fastening screws, which can not only effectively improve the construction efficiency but also effectively ensure no water leakage.

[0071] In order to facilitate the pressing of the pressing block 721 and the frame 21 of the photovoltaic assembly 2 , any pressing block 721 is further provided with a limiting protrusion 7212 , and the limiting protrusion 7212 abuts against the frame 21 of the corresponding photovoltaic assembly 2 .

[0072] In this way, one end of the pressure block 721 is snap-connected with the outer wall of the confluence and drainage structure 71, and the other end of the pressure block 721 is abutted against the frame 21 of the photovoltaic component 2, wherein the frame 21 of the photovoltaic component 2 is accommodated in the U-shaped groove of the water-guiding structure, and the water-guiding structure is embedded in the confluence and drainage structure 71, so that the confluence and drainage structure 71 and the water-guiding structure can be fixed to the frame 21 of the corresponding photovoltaic component 2.

[0073] In order to facilitate the connection between the water guiding structure and the confluence water structure 71, the confluence water structure 71 includes a transverse limiting opening 712 extending in the transverse direction and a longitudinal limiting opening 713 extending in the longitudinal direction. One end of the transverse water guiding structure 5 is embedded in the transverse limiting opening 712, and one end of the longitudinal water guiding structure 6 is embedded in the longitudinal limiting opening 713.

[0074] In this embodiment, both ends of the converging water discharge structure 71 are provided with transverse limiting openings 712 in the transverse direction, so that the two transverse water-guiding structures 5 can be respectively embedded in the two transverse limiting openings 712, and both ends of the converging water discharge structure 71 are provided with longitudinal limiting openings 713 in the longitudinal direction, so that the two longitudinal water-guiding structures 6 can be respectively embedded in the two longitudinal limiting openings 713.

[0075] In addition, the converging drainage structure 71 further includes a drainage port 714 , two transverse limiting ports 712 and two longitudinal limiting ports 713 may be evenly arranged on the periphery of the drainage port 714 , and the drainage port 714 is arranged toward the longitudinal drainage structure 8 .

[0076] In this way, the rainwater guided by the transverse water guiding structure 5 and the longitudinal water guiding structure 6 can be collected at the drain port 714 of the converging drain structure 71 , and flow from the drain port 714 to the longitudinal drainage structure 8 .

[0077] In some embodiments, the converging and draining structure 71 is provided with a slot 715, please refer to Fig.10 The longitudinal drainage structure 8 is provided with a folded edge 81 folded inwardly, and the folded edge 81 is engaged with the card slot 715 to connect the longitudinal drainage structure 8 and the converging drainage structure 71 .

[0078] In this way, one end of the longitudinal drainage structure 8 can be slidably inserted into the groove 715 of the converging drainage structure 71 through the folded edge 81 .

[0079] Furthermore, the waterproof device of the photovoltaic module 2 also includes a detachable connecting component 9, through which the longitudinal drainage structure 8 and the lowest purlin 1 are connected, so that the longitudinal drainage structure 8 can be detachably fixed to the lowest purlin 1.

[0080] That is to say, in order to facilitate the fixing of the longitudinal drainage structure 8, one end of the longitudinal drainage structure 8 is clamped and fixed to the converging drainage structure 71, and the longitudinal drainage structure 8 is fixed to the purlin 1 at the lowest position through the detachable connecting component 9.

[0081] Please also read Figure 4 , Figure 5 and Fig.11 The detachable connection component 9 can be a clamp component. Specifically, the clamp 91 component includes a clamp 91 and a self-tapping screw 92. The clamp 91 embraces the outside of the longitudinal drainage structure 8. The self-tapping screw 92 connects the clamp 91 and the purlin 1 at the lowest position, so that the longitudinal drainage structure 8 can be fixed under the purlin 1 at the lowest position.
