[0048] See also Figures 1 to 14An embodiment of the utility model provides a ridge rainproof member for use in a photovoltaic system, wherein the photovoltaic system includes a first roof 600, a second roof 700, a photovoltaic module 100, a main water tank 200 and a ridge rainproof member, wherein the second roof 700 is arranged at an angle to the first roof 600; a plurality of photovoltaic modules 100 arranged in an array are arranged on the first roof 600 and the second roof 700; a plurality of main water tanks 200 spaced apart along a first direction X are arranged on the first roof 600 and the second roof 700; the main water tank 200 is arranged between the photovoltaic module 100 and the first roof 600 or the second roof 700, and corresponds to a first gap 110 between two adjacent photovoltaic modules 100, and the first gap 110 and the main water tank 200 both extend along the first direction X; the ridge rainproof member is covered at the ridge 400 formed by the intersection of the first roof 600 and the second roof 700.
[0049] like Figures 1 to 3 As shown, the utility model provides a ridge rainproof member, the first roof 600 and the second roof 700 are arranged at an angle, and the intersection of the two roofs forms a ridge 400. By arranging a plurality of photovoltaic modules 100 distributed in an array on the first roof 600 and the second roof 700, the roof can convert solar energy into electrical energy to achieve power generation. By arranging a main water tank 200 on the first roof 600 and the second roof 700, and arranging the main water tank 200 between the photovoltaic module 100 and the first roof 600 or the second roof 700, and arranging the main water tank 200 in the gap between the two photovoltaic modules 100, and the main water tank 200 extends along the first direction X, rainwater flows into the main water tank 200 from the first gap 110 between the two photovoltaic modules 100, and is discharged through the main water tank 200.
[0050] like Figure 4 As shown, it can be understood that the first roof 600 and the second roof 700 intersect to form a gable roof, and a raised ridge 400 is provided at the intersection of the first roof 600 and the second roof 700, and the ridge 400 extends along the second direction Y. The first roof 600 and the second roof 700 are arranged on both sides of the ridge 400 along the first direction X. A plurality of photovoltaic modules 100 distributed in an array are arranged on the first roof 600 and the second roof 700, and a first gap 110 and a second gap 120 are formed between adjacent photovoltaic modules 100, and the first gap 110 extends along the first direction X, and the second gap 120 extends along the second direction Y. The first direction X and the second direction Y are perpendicular to each other.
[0051] It should be noted that, in the present application, the first direction is the arrangement direction of the first roof and the second roof, and the second direction is the extension direction of the ridge.
[0052] It should be understood that the first roof 600 and the second roof 700 are arranged at an inclination, wherein the ends of the first roof 600 and the second roof 700 away from the ridge 400 are inclined downward. The main water tank 200 is arranged below the first gap 110, and the end of the main water tank 200 away from the ridge 400 is also arranged at an inclination downward, so that when rainwater flows from the ridge 400 into the water guide 360, and flows from the water guide 360 into the main water tank 200, or flows into the main water tank 200 through the first gap 110, the rainwater is discharged by the inclination of the main water tank 200, thereby improving the drainage performance of the ridge 400.
[0053] like Figures 5 to 8 As shown, in one embodiment, the ridge rainproof member 300 includes a cover plate 310, a supporting wall plate 320, a first bottom plate 330 and a water retaining plate 340, and the cover plate 310 is covered on the ridge 400; the cover plate 310 is respectively connected to the supporting wall plate 320 at both ends along the first direction X, and the supporting wall plate 320 and the cover plate 310 are arranged at an angle; the bottom plate 330 is connected to the end of the supporting wall plate 320 away from the cover plate 310; the water retaining plate 340 is connected to the end of the bottom plate 330 away from the supporting wall plate 320; wherein the supporting wall plate 320, the bottom plate 330 and the water retaining plate 340 enclose and construct a water guide channel 360.
[0054] In this embodiment, the support wall panels 320 are connected at both ends of the cover plate 310 in the width direction, so that the cover plate 310 and the two support wall panels 320 surround a U-shaped groove, and the structure formed by the cover plate 310 and the two support wall panels 320 is buckled on the ridge 400. The inclination angle of the bottom plate 330 is consistent with the slope of the first roof or the second roof, so that after the frame of the photovoltaic module is supported on the bottom plate 330, the inclination angle of the photovoltaic module is consistent with the first roof or the second roof. By setting the bottom plate 330 and the water retaining plate 340, a water guide trough 360 is formed on both sides of the support wall panel 320 to discharge rainwater on the cover plate 310.
[0055] It is understandable that, since the cover plate 310 is provided on the roof ridge 400, the cover plate 310 is used to prevent rainwater from leaking into the roof ridge 400. By connecting the water channel 360 and the main water channel 200, rainwater flows downward from the cover plate 310 along the supporting wall plate 320 into the water channel 360, and then is discharged from the main water channel 200. The length of the cover plate 310 and the supporting wall plate 320 along the second direction Y should not be less than the length of the photovoltaic module 100 after splicing along the second direction Y.
[0056] like Figure 3 , Figures 8 to 11As shown, in one embodiment, a rain gutter 331 is provided on the bottom plate 330, and the rain gutter 331 is correspondingly arranged above the main water tank 200, so that the water guide groove 360 is connected to the main water tank 200. By providing the rain gutter 331 on the bottom plate 330 and correspondingly arranging the rain gutter 331 above the main water tank 200, the water in the water guide groove 360 is drained through the rain gutter 331.
[0057] There is no limitation on the specific structure of the rain gutter 331. In some embodiments, Figure 8 and Fig. 9 As shown, a plurality of spaced bottom plates 330 are provided in the extension direction of the supporting wall plate 320, and the gap between two adjacent bottom plates 330 is the above-mentioned rain gutter 331. Accordingly, the water retaining plate 340 forms a notch identical to the rain gutter 331 at a position corresponding to the rain gutter 331. It is worth noting that the gap between two adjacent bottom plates 330 should be provided at the first gap 110 between two photovoltaic modules 100 and located above the main water tank 200. In other embodiments, such as Fig.10 and Fig.11 As shown, a waist-shaped hole or a plurality of through holes arranged at intervals may be provided above the main water tank 200 on the bottom plate 330. These through holes may be circular holes, square holes, diamond holes, etc. It should be understood that the size of the rain drain 331 is not limited, as long as it can effectively dredge the rainwater in the water guide trough 360 and ensure that the rainwater can flow into the main water tank 200.
[0058] like Figure 7 As shown, in one embodiment, the ridge rainproof member 300 further includes an anti-overflow plate 350, one end of which is fixedly connected to the water retaining plate 340, and the anti-overflow plate 350 covers a portion of the notch of the water guide groove 360. By arranging the anti-overflow plate 350 on the water retaining plate 340, on the one hand, it is helpful to prevent rainwater in the water guide groove 360 from overflowing from the upper edge of the water retaining plate, and on the other hand, the anti-overflow plate 350 also has the advantage of strengthening the structural strength of the entire ridge rainproof member 300.
[0059] In one embodiment, the cover plate 310, the supporting wall plate 320, the bottom plate 330, the water retaining plate 340 and the anti-overflow plate 350 are an integrated structure or an integrated molded structure. Specifically, the ridge rainproof member 300 can be formed by a bending molding process or a hot extrusion process, which has the advantages of simple process and high strength.
[0060] Specifically, the cover plate 310 is configured to be V-shaped or curved. The cover plate 310 is configured to be V-shaped or curved so that rainwater can be guided through the V-shaped or curved surface, thereby facilitating rainwater to flow into the water guide groove 360 .
[0061] In this embodiment, the height of the water retaining plate 340 can be pre-judged in combination with the height of the photovoltaic module 100 and the size of the gap between the supporting wall plate 320 and the side of the photovoltaic module 100 to set a reasonable height. For example, if the photovoltaic module 100 and the supporting wall plate 320 are in close contact, the water retaining plate 340 only needs to be slightly higher to form the water channel 360.
[0062] like Fig.12 As shown, in one embodiment, the ends of the cover plate at both ends along the first direction X cover the ends of the photovoltaic modules on both sides of the ridge. This arrangement allows rainwater at the ridge to flow into the main water tank only along the first gap between the photovoltaic modules, and then be discharged through the main water tank.
[0063] As for the connection between the photovoltaic module 100 and the ridge rainproof member 300, the photovoltaic module 100 on the first roof 600 is installed first. During installation, the side frame 130 of the photovoltaic module 100 is first placed in the water channel 360. After all the photovoltaic modules 100 are placed in place, the side and bottom of the photovoltaic module 100 located at the edge are immediately locked with the roof tile using a locking assembly, so that the photovoltaic module 100 is relatively fixed to the roof, thereby preventing the module from sliding downward, resulting in a large gap between the photovoltaic module 100 and the supporting wall plate 320, thereby causing excessive rainwater to flow into the water channel 360. After the photovoltaic module 100 is locked, the surface where the frame 130 of the photovoltaic module 100 contacts the bottom plate 330 will press the bottom plate 330. After installing the photovoltaic module 100 on one roof, install the photovoltaic module 100 on another roof. During installation, the photovoltaic module 100 is pressed against the supporting wall plate 320 by external force, and the photovoltaic module 100 and the supporting wall plate 320 are tightly pressed against each other to generate friction, thereby achieving the effect of locking the ridge rainproof member 300. Specifically, the C surface of the frame of the photovoltaic module, that is, the surface supported on the bottom plate, is pressed into the water guide groove to achieve compression, and the B surface of the photovoltaic module, that is, the surface opposite to the supporting wall plate 320, is pressed against the supporting wall plate 320 to lock the ridge rainproof member. Such a setting avoids the use of external tools such as screws for anchoring, which generates additional costs, simplifies the construction procedures, and reduces the construction process.
[0064] The angle of the V-shaped surface of the cover plate 310 can be different, and the appropriate angle is selected in combination with the actual situation. When the height of the water retaining plate 340 is sufficient for drainage requirements, the overflow plate 350 can also be removed. A leakage hole for diverting water to the main water tank 200 is provided at the intersection of the ridge rainproof member 300 and the main water tank 200, so that the water in the water guide groove 360 flows to the main water tank 200. The diversion hole can be a diversion gap, or it can be elliptical or circular. In order to prevent rainwater from flowing back and flowing back to the roof along the bottom of the water guide groove 360, diversion measures can also be provided at the leaking groove 331, such as bending or setting a guide plate. For example, a guide plate arranged to be inclined downward is designed at the leaking groove 331 to facilitate diversion.
[0065] In this embodiment, the frame 130 of the photovoltaic component 100 is placed in the water guide groove 360, the outer wall of the photovoltaic component 100 is in contact with the inner surface of the water guide groove 360, and the width of the surface where the frame 130 of the photovoltaic component 100 contacts the bottom plate 330 is no greater than the width of the water guide groove 360, so that the frame 130 of the photovoltaic component 100 can be easily placed in the water guide groove 360.
[0066] Along the second direction, two adjacent ridge rainproof pieces are buckled with each other. The two adjacent ridge rainproof pieces are buckled up and down. The buckled parts at both ends of the ridge rainproof piece can not only make the cover plate form a tight effect; even if the rain is too heavy and causes water seepage at the ridge 400, the buckled part can store water because the buckled part is at the gap of the photovoltaic module 100.
[0067] like Fig.13 and Fig.14 As shown, specifically, the ridge flashing piece 300 is provided with a first snap-in groove 370 and a second snap-in groove 380 at both ends along the second direction, respectively. The slot of the first snap-in groove 370 faces the side away from the cover plate, and the slot direction of the second snap-in groove 380 is opposite to the slot direction of the first snap-in groove 370; wherein, the height of the slot side walls of the first snap-in groove 370 and the second snap-in groove 380 that are away from each other is lower than the height of the slot side walls on the other side, and the side slot wall of the first snap-in groove 370 of one ridge flashing piece 300 is snap-fitted with the second snap-in groove 380 of another ridge flashing piece 300.
[0068] By setting the first clamping groove 370 and the second clamping groove 380 at both ends of the ridge flashing piece, and setting the opening directions of the two clamping grooves in opposite forms, the side wall of the clamping groove at one end of one ridge flashing piece 300 can be correspondingly clamped into the clamping groove of the other ridge flashing piece 300. In addition, by setting the side walls of the ends of the two clamping grooves away from each other to the height of the groove side walls on the other side, after the two ridge flashing pieces 300 are clamped together, the cover plates of the two ridge flashing pieces 300 are in the same plane. This is not only conducive to waterproofing, but also more beautiful.
[0069] like Figure 3 As shown, in one embodiment, the photovoltaic roof also includes a plurality of drainage grooves 500, the drainage grooves 500 are arranged at intervals along the first direction X, the drainage grooves 500 extend along the second direction Y, the drainage grooves 500 are arranged below the second gap 120 extending along the second direction Y between two adjacent photovoltaic components 100, and the two ends of the drainage grooves 500 are respectively connected to the two adjacent main water tanks 200.
[0070] By arranging the drainage groove 500 below the second gap 120 between adjacent photovoltaic modules 100, and connecting the drainage groove 500 with the main water tank 200, rainwater can flow into the drainage groove 500 from the second gap, and then flow into the main water tank 200 from the drainage groove 500 and be discharged. In this embodiment, the water guide groove 360, the drainage groove 500 and the main water tank 200 form a drainage system of the photovoltaic system, or the drainage groove 500 and the main water tank 200 form a drainage system of the photovoltaic system.
[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0072] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
