[0045] Referring to Figures 1 to 10 , an embodiment of the present utility model provides a ridge connector 300 for a photovoltaic system. The photovoltaic system includes a first photovoltaic module 100 and a second photovoltaic module 200 arranged at an angle. The ridge connector 300 includes a cover plate 310, a support plate 320 and a bottom plate 330. The cover plate 310 covers the gap between the first photovoltaic module 100 and the second photovoltaic module 200, and both ends of the cover plate 310 along the first direction X shield the opposite ends of the first photovoltaic module 100 and the second photovoltaic module 200; two support plates 320 are arranged at intervals along the first direction X, and one end of the support plate 320 is fixedly connected to the cover plate 310; two bottom plates 330 are respectively connected to the ends of the two support plates 320 facing away from the cover plate 310; wherein, the cover plate 310, the support plate 320 and the bottom plate 330 enclose and define two installation grooves 360, and the two installation grooves 360 are respectively used for being clamped with the first photovoltaic module 100 and the second photovoltaic module 200; the two installation grooves 360 are arranged at an angle so that the angle between the first photovoltaic module 100 and the second photovoltaic module 200 meets a preset angle.

[0046] The present technical solution provides a ridge connector 300 for connecting a first photovoltaic module 100 and a second photovoltaic module 200 arranged at an angle. A cover plate 310 is covered on the gap between the first photovoltaic module 100 and the second photovoltaic module 200, and both ends of the cover plate 310 along the first direction X block the opposite ends of the first photovoltaic module 100 and the second photovoltaic module 200, so as to block rainwater through the cover plate 310, thereby preventing rainwater from flowing on the roof through the gap between the first photovoltaic module 100 and the second photovoltaic module 200. Two installation grooves 360 are defined by enclosing between the cover plate 310, the support plate 320 and the bottom plate 330, and the first photovoltaic module 100 and the second photovoltaic module 200 are respectively clamped with the installation grooves 360 to realize the mutual connection between the first photovoltaic module 100 and the second photovoltaic module 200. The two installation grooves 360 are arranged at an angle, and the angle between the two installation grooves 360 is adapted to the preset angle between the first photovoltaic module 100 and the second photovoltaic module 200, so that after the first photovoltaic module 100 and the second photovoltaic module 200 are clamped with the installation grooves 360, the included angle between the first photovoltaic module 100 and the second photovoltaic module 200 reaches the preset angle. Through the above structure, while improving the waterproof performance at the ridge 800, the connection between the first photovoltaic module 100 and the second photovoltaic module 200 can be realized.

[0047] It should be noted that in the present application, the first direction X is the direction in which the first roof surface and the second roof surface are arranged; the second direction Y is the extending direction of the ridge, wherein the first direction X and the second direction Y are perpendicular to each other.

[0048] As Figure 6 shown, specifically, the cover plate 310 includes a first side plate 311 and a second side plate 312 connected to each other. The first side plate 311 and the second side plate 312 are arranged at an angle. The two support plates 320 are respectively connected to the first side plate 311 and the second side plate 312. The first side plate 311, the support plate 320 and the bottom plate 330 enclose and define an installation groove 360, and the second side plate 312, the support plate 320 and the bottom plate 330 enclose and define another installation groove 360. As a preferred embodiment, the support plate 320 is perpendicular to the first side plate 311 or the second side plate 312; the bottom plate 330 is perpendicular to the support plate 320 connected thereto.

[0049] With the above structural form, the two oppositely arranged mounting grooves 360 are arranged at an angle, so that a preset angle is formed between the first photovoltaic module 100 and the second photovoltaic module 200 after being clamped with the mounting grooves 360. It can be understood that the included angle formed between the first side plate 311 and the second side plate 312 is consistent with the preset included angle to be formed between the first photovoltaic module 100 and the second photovoltaic module 200. The support plate 320 is perpendicular to the first side plate 311 or the second side plate 312, and the bottom plate 330 is perpendicular to the connected support plate 320, so that the two bottom plates 330 are respectively parallel to the first side plate 311 and the second side plate 312, so that the bottom plate 330, the first side plate 311 and the second side plate 312 can clamp the first photovoltaic module 100 and the second photovoltaic module 200, so as to improve the connection reliability of the first photovoltaic module 100 and the second photovoltaic module 200.

[0050] Refer to Figure 7 and Figure 8 It should be understood that in one embodiment, the ridge connector 300 further includes a water baffle 340. The water baffle 340 is arranged at one end of the bottom plate 330 facing away from the support plate 320. The water baffle 340, the bottom plate 330 and the support plate 320 jointly define a water guide groove 370, and the water guide groove 370 is used to communicate with the main water groove 400 on the photovoltaic system.

[0051] By arranging the water baffle 340 at one end of the bottom plate 330 facing away from the support plate 320, the water guide groove 370 is jointly enclosed and defined by the water baffle 340, the bottom plate 330 and the support plate 320, and the water guide groove 370 is communicated with the main water groove 400, so that even if the rainwater flowing down from the ridge 800 flows down through the gap between the photovoltaic module and the support plate 320, it can flow into the main water groove 400 through the water guide groove 370 and be discharged. Through the above structural form, the waterproof performance of the ridge connector 300 can be further improved, thereby improving the waterproof performance of the photovoltaic system.

[0052] In one embodiment, the bottom plate is provided with hydrophobic holes, and the hydrophobic holes are arranged above the notch of the main water groove. By arranging the hydrophobic holes on the bottom plate and arranging the hydrophobic holes above the notch of the main water groove, the communication between the water guide groove and the main water groove is realized, so that the water in the water guide groove can flow into the main water groove through the hydrophobic holes and then be discharged through the main water groove.

[0053] Continue to refer to Figure 7 and Figure 8It is understood that in one embodiment, the ridge connector 300 further includes an overflow plate 350. The overflow plate 350 is connected to the end of the water baffle 340 facing away from the bottom plate 330, and the overflow plate 350 corresponds to the notch of the water guide groove 370. By providing the overflow plate 350 at the notch of the water guide groove 370, rainwater is prevented from overflowing from the edge of the water baffle 340, thereby further improving the waterproof performance of the ridge connector 300.

[0054] In one embodiment, the ridge connector 300 is formed by hot extrusion. Forming by hot extrusion has the advantages of simple process, easy processing, and near-net shaping. Specifically, the ridge connector 300 can be made of aluminum alloy material.

[0055] In one embodiment, along the second direction Y, two adjacent ridge connectors 300 are buckled with each other. Refer to Figure 9 and Figure 10 It is understood that specifically, the two ends of the ridge connector 300 along the second direction Y are respectively provided with a first clamping groove and a second clamping groove. The notch of the first clamping groove faces away from the side of the cover plate 310, and the notch direction of the second clamping groove is opposite to the notch direction of the first clamping groove; wherein, the height of the side wall of the first clamping groove and the second clamping groove away from each other is lower than the height of the other side wall, and the side wall of the first clamping groove of one ridge connector 300 is clamped with the second clamping groove of another ridge connector 300.

[0056] It should be noted that the second direction Y is a direction perpendicular to the first direction X, and more specifically, it is a direction along the extension direction of the ridge 800 of the house. During installation, the connection of two adjacent ridge connectors 300 is realized by buckling the two adjacent ridge connectors 300. Specifically, by providing the first clamping groove and the second clamping groove at both ends of the ridge connector 300 and setting the opening directions of the two clamping grooves to be opposite, the side wall of the clamping groove at one end of one ridge connector 300 can be correspondingly clamped into the clamping groove of another ridge connector 300. In addition, by setting the height of the side wall of the end of the two clamping grooves away from each other to be the height of the side wall of the other side, after the two ridge connectors 300 are clamped with each other, the cover plates 310 of the two ridge connectors 300 are in the same plane. This is not only beneficial to waterproofing but also more beautiful.

[0057] Such as Figures 1 to 3As shown in the figure, an embodiment of the present utility model further provides a photovoltaic system. The photovoltaic system includes the ridge connector 300 as described above. The photovoltaic system further includes a first roof surface 600 and a second roof surface 700 arranged at an angle. A plurality of first photovoltaic modules 100 arranged in an array are provided on the first roof surface 600, and a plurality of second photovoltaic modules 200 arranged in an array are provided on the second roof surface 700. The ridge connector 300 is covered at the ridge 800 formed by the intersection of the first roof surface 600 and the second roof surface 700. The frames 130 of the first photovoltaic module 100 and the second photovoltaic module 200 are respectively clamped with the two installation grooves 360.

[0058] In this technical solution, by providing the first photovoltaic modules 100 arranged in an array on the first roof surface 600 and the second photovoltaic modules 200 arranged in an array on the second roof surface, the photovoltaic system can convert solar energy into electrical energy and has a power generation function. The ridge connector 300 is covered at the ridge 800 formed by the intersection of the first roof surface 600 and the second roof surface 700 to prevent rainwater from flowing into the roof surface from the ridge 800. By clamping the frames 130 of the first photovoltaic module 100 and the second photovoltaic module 200 with the two installation grooves 360 of the ridge connector 300, the first photovoltaic module 100 and the second photovoltaic module 200 on both sides of the ridge 800 are connected through the ridge connector 300, thereby ensuring the reliability of the operation of the photovoltaic system.

[0059] As Figures 1 to 3 shown, in one embodiment, a plurality of main water troughs 400 arranged at intervals along the second direction Y and a plurality of drain troughs 500 arranged at intervals along the first direction X are provided on both the first roof surface 600 and the second roof surface 700. The main water troughs 400 are arranged between the photovoltaic modules and the first roof surface 600 or the second roof surface 700 and correspond to the first gap 110 between two adjacent photovoltaic modules. Both the first gap 110 and the main water troughs 400 extend along the first direction X. The drain troughs 500 are arranged between the photovoltaic modules and the first roof surface 600 or the second roof surface 700 and correspond to the second gap 120 between two adjacent photovoltaic modules. Both the second gap 120 and the drain troughs 500 extend along the second direction Y. Among them, both ends of the drain troughs 500 are respectively communicated with two adjacent main water troughs 400, and the rainwater at the ridge 800 flows into the main water troughs 400 from the gap between the two photovoltaic modules and is discharged.

[0060] By arranging main water troughs 400 which are spaced along the second direction Y on the first roof 600 and the second roof 700, making the first gap 110 between the main water troughs 400 correspond to the photovoltaic modules, so that when rainwater flows downward along the inclination angle of the first photovoltaic module 100 or the second photovoltaic module 200, it flows into the main water trough 400 through the first gap 110 and then is discharged through the main water trough 400. By arranging drain troughs 500 which are spaced along the first direction X on the first roof 600 and the second roof 700, connecting both ends of the drain troughs 500 with two adjacent main water troughs 400, making the second gap 120 between two adjacent photovoltaic modules correspond to the drain troughs 500, so that when rainwater flows downward along the inclined surface of the first photovoltaic module 100 or the second photovoltaic module 200, it flows into the drain trough 500 through the second gap 120 and then flows into the main water trough 400 through the drain trough 500 and is discharged. Through the above structural form, the waterproof performance at the ridge 800 is improved, and the structure is simple and the cost is low.

[0061] The technical features of the above-described embodiments can be combined arbitrarily.
