The first through hole 52 is suitable for making way for the screw 42, and the inner wall of the first through hole 52 is abutted against the outer peripheral wall of the screw 42, which is beneficial to improving the installation stability of the insulating structure 5.

[0055] In some embodiments, in combination Figures 1 to 5 As shown, a through hole 51 is formed at a position of the insulating structure 5 corresponding to the drain hole 131 .

[0056] Preferably, the diameter of the through hole 51 is matched with the diameter of the downhole 131 to make way for rainwater in the gutter 1 to enter the drainage pipe 2 , and the rainwater in the gutter 1 is suitable to enter the drainage pipe 2 through the through hole 51 and the downhole 131 .

[0057] In some embodiments, in combination Figures 1 to 5 As shown, the gutter drainage pipe assembly also includes an anti-debris structure 3, which is arranged on the side of the fixing plate 41 away from the bottom plate 13 and covers the top of the water drop hole 131.

[0058] The gutter drainage pipe assembly provided in this embodiment is provided with an anti-debris structure 3 on the side of the fixing plate 41 away from the bottom plate 13 to prevent debris from entering the downspout 131, thereby ensuring that rainwater in the gutter 1 can smoothly enter the downspout through the downspout 131.

[0059] In some embodiments, in combination Figures 1 to 5 As shown, the anti-debris structure 3 includes a plurality of guide plates 31 fixedly connected to the side of the fixed plate 41 away from the bottom plate 13, and the plurality of guide plates 31 are radially distributed around the axis of the water drop hole 131 to form a plurality of gaps; the anti-debris structure 3 also includes a connecting plate 32, which is located at one end of the guide plate 31 away from the fixed plate 41 and is fixedly connected to the plurality of guide plates 31 at the same time.

[0060] The gutter drainage pipe assembly provided in this embodiment guides the flow direction of rainwater through the guide plate 31, which is beneficial to improving the stability of rainwater discharge from the gutter 1 at the downspout 131, and is fixedly connected with a connecting plate 32 at one end of the guide plate 31 away from the fixed plate 41, so as to be suitable for intercepting debris lifted up as the water level rises.

[0061] Specifically, the fixed connection between the guide plate 31 and the fixing plate 41 includes welding and bolt connection. Preferably, the spacing between two adjacent guide plates 31 is the same, and the plane where the guide plate 31 is located is perpendicular to the plane where the fixing plate 41 is located. There is a gap between two adjacent guide plates 31, so that the rainwater in the gutter 1 can enter the water hole 131 through the gap and intercept the debris coming with the water flow, thereby preventing the debris from clogging the water hole 131; the guide plate 31 can also play a role in guiding rainwater, which is conducive to the rainwater in the gutter 1 to flow efficiently into the drainage pipe 2. The connecting plate 32 is fixedly connected to the end of the guide plate 31 away from the fixing plate 41, and covers the water outlet, so as to be suitable for blocking the debris lifted up with the water level rising and the debris falling from the top of the gutter, and is fixedly connected to multiple guide plates 31 at the same time through the connecting plate 32, so as to improve the overall stability of the anti-debris structure.

[0062] In some embodiments, in combination Figures 1 to 5 As shown, the second side panel 12 includes a first straight portion 121 arranged vertically, and a second straight portion 122 located at one end of the first straight portion 121 away from the bottom plate 13 and arranged at an angle to the first straight portion 121, and the angle between the second straight portion 122 and the direction of gravity is adapted to the angle between the sloping roof and the direction of gravity.

[0063] The gutter drainage pipe assembly provided in this embodiment makes the inclination direction of the second straight portion 122 match the inclination direction of the sloping roof, so as to improve the connection stability between the second straight portion 122 and the sloping roof when the second straight portion 122 is fixedly connected to the sloping roof.

[0064] Specifically, the inclination direction of the second straight portion 122 matches the inclination direction of the sloping roof, so as to be fixedly connected to the sloping roof, and the fixed connection forms include welding and bolting. The gutter 1 is suitable for forming a fixed connection with the sloping roof through the second straight portion 122.

[0065] In some embodiments, in combination Figures 1 to 5 As shown, along the horizontal direction and perpendicular to the extension direction of the gutter 1 , the projection of the first side plate 11 covers the projection of the first straight portion 121 .

[0066] The gutter drainage pipe assembly provided in this embodiment makes the height of the first side plate 11 in the gravity direction equal to or greater than the height of the first straight portion 121, so that the gutter 1 can accommodate more rainwater and reduce splashing of rainwater.

[0067] Specifically, the first side plate 11 and the bottom plate 13 are arranged at an angle, and along the gravity direction, the top elevation of the first straight portion 121 is defined as the first height. When the top elevation of the first side plate 11 is lower than the first height, the highest liquid level of rainwater that the gutter 1 can accommodate is the same as the top elevation of the first side plate 11. At this time, the amount of rainwater that the gutter 1 can accommodate is limited by the height of the first side plate 11. Figure 3 and Figure 4 As shown, along the horizontal direction and perpendicular to the extension direction of the gutter 1, the projection of the first side panel 11 covers the projection of the first straight portion 121. At this time, the top elevation of the first side panel 11 is equal to or greater than the first height. Compared with when its top elevation is less than the first height, it can accommodate more rainwater, which can reduce the splashing of rainwater on the sloping roof in the process of flowing to the gutter 1, and when the rainwater flow rate is large, it can also prevent rainwater from rushing out of the gutter 1 along the sloping roof.
