DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 The figure shows a photovoltaic roof gutter with photovoltaic panels 2 mounted above the roof 1. The panels are mounted on galvanized steel brackets and BIPV waterproof brackets. This design of adding photovoltaic panels 2 to the roof 1 not only provides power to the equipment inside the house, but also improves the waterproofing of the roof 1.

[0026] A first gutter 3 is fixedly provided on the side of the roof 1. The first gutter 3 is U-shaped and includes a first gutter wall 31, a first gutter bottom 32, and a first drainage pipe 33. The first gutter wall 31 is fixedly provided on both sides of the first gutter bottom 32. A first drainage pipe 33 is fixedly provided at the bottom of the first gutter bottom 32.

[0027] The drainage gutter also includes a second gutter 4, which is fixed to the inner surface of the first gutter 33. A second drain port 41 is formed at the location corresponding to the first drain pipe 33. Water entering the second gutter 4 is collected and discharged through the second drain port 42. The double-layer gutter design enhances the overall drainage and waterproofing effects of the drainage gutter. Preferably, the second gutter 4 is made of stainless steel or aluminum alloy.

[0028] The shape of the second groove 4 is adapted to that of the first groove 3, and includes a second groove wall 43, a second groove wall 44 and a second groove bottom 47. The second groove wall 43 and the second groove wall 44 are respectively fixed at both ends of the second groove bottom 47, and the second groove wall 43 and the second groove wall 44 are respectively arranged close to the first groove wall 31 on the corresponding side.

[0029] The second drain opening 41 is formed at the bottom of the second ditch bottom 47. A second drain pipe 42 is fixedly installed below the second drain opening 41. The second drain pipe 42 is sleeved inside the first drain pipe 33. The position and number of the second drain openings 41 are consistent with the position and number of the first drain pipes 33.

[0030] There is a gap between the second ditch bottom 47 and the first ditch bottom 32, and a gap between the second drain pipe 42 and the first drain pipe 33. This gap is used to drain small amounts of rainwater that seeps between the first and second ditch gutters 3 and 4. The second drain pipe 42 is placed as close to the first drain pipe 33 as possible. Preferably, the gap between the second ditch bottom 47 and the first ditch bottom 32 is 10-20 cm. The second ditch is primarily secured by the second side panel 1 45 being crimped to the roof 1 and the second side panel 46 being crimped to the first ditch wall 31.

[0031] The upper end of the second groove wall 43 is fixedly connected to the second side plate 45, which extends above the roof 1 and is disposed close to the roof 1. Preferably, the second groove wall 43 and the second side plate 45 are integrally formed or welded.

[0032] Second side panel 1 (45) extends below photovoltaic panel 2. Rainwater falling on photovoltaic panel 2 flows along the surface of photovoltaic panel 2 through second side panel 1 (45) and into secondary gutter 4. Preferably, the length of second side panel 1 (45) extending below photovoltaic panel 2 is 0.5-1.0 meters, with a preferred length of 0.7 meters.

[0033] A second side plate 46 is fixedly connected to the upper end of the second groove wall 44. The second side plate 46 covers the gap between the second groove wall 44 and the corresponding first groove wall 31. The second side plate 46 is disposed close to the first groove wall 31. The second groove wall 44 and the second side plate 46 are integrally formed or welded together, and simultaneously cover the gap between the second groove wall 44 and the corresponding first groove wall 31 to prevent rainwater from entering the first groove 3.

[0034] When the second side plate 46 is a flat plate, it forms a "7"-shaped structure with the second groove wall 44.

[0035] When the second side plate 46 and the second ditch wall 44 form a "J"-shaped structure, they can wrap the upper end of the first ditch wall 31 on the corresponding side to prevent rainwater from entering the gap between the first ditch 3 and the second ditch 4.

[0036] The second side plate 46 is provided with a fixing connector 48 for fixing the second second gutter 4. The fixing connector 48 can be a bolt or other connector that can fix the second gutter 4 to the first gutter 3.
