Description

Technical Field

[0001] This utility model belongs to the field of building drainage technology, and in particular relates to a structure for a building roof gutter and an anti-clogging drain outlet. Background Technology

[0002] Gutters are an important part of a building's roof drainage system. They are mainly used to collect and channel rainwater from the roof. Gutters are installed at the edge or lower part of the roof. By utilizing the slope of the roof, rainwater can flow naturally into the gutter. The gutter, through its own slope, guides the collected rainwater to the drain outlet, and then through the drain pipe connected to the drain outlet to the ground or underground drainage system.

[0003] During roof drainage, drain outlets are easily clogged by leaves, debris, and other contaminants carried by rainwater. A single-outlet design can lead to overflow after clogging. During periods of heavy rainfall, the drainage speed of the drain outlets cannot keep up with the rainwater accumulation, resulting in increased water depth in the gutters. This can cause rainwater to backflow onto the roof and even into the interior, damaging the building and interior items. Therefore, a roof gutter and anti-clogging drain outlet structure is needed, employing a two-stage filtration and one-stage interception system to block foreign objects in the accumulated water. It also features a high-level drainage hole for secondary drainage in extreme weather or when the low-level drainage hole is clogged, effectively preventing water overflow. Utility Model Content

[0004] The purpose of this utility model is to provide a roof gutter and anti-clogging drain structure for buildings.

[0022] In the following description, embodiments of the building roof gutter and anti-clogging drain structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a roof gutter and anti-clogging drain structure according to an embodiment of the present invention, including a gutter 1 installed on the roof of a building. A pre-embedded drain pipe 2 is fixedly installed at the bottom of the gutter 1. An mounting plate 3 is provided at the bottom of the inner cavity of the gutter 1, and a sealing ring 7 is engaged at the bottom of the mounting plate 3. A waterproof gasket 8 is glued to the bottom of the inner cavity of the gutter 1. The sealing ring 7 is tightly pressed against the surface of the waterproof gasket 8. Through the cooperation of the sealing ring 7 and the waterproof gasket 8, a seal is formed between the mounting plate 3 and the gutter 1, thereby preventing water seepage at the connection point and ensuring that accumulated water is discharged from a designated location. Expansion bolts 9 are threaded to the four corners of the top of the mounting plate 3. The bottom ends of the expansion bolts 9 penetrate to the bottom of the mounting plate 3 and are threaded to the gutter 1. A drain pipe 4 is fixedly connected to the bottom of the mounting plate 3. Tapping threads 10 are provided on both sides of the drain pipe 4. The opposite ends of the two taps 10 penetrate to the inner cavity of the drain pipe 4 and are threaded to the outer connecting pipe 63. 4. The drain pipe 4 is inserted into the inner cavity of the pre-embedded drain pipe 2. The surface of the drain pipe 4 is provided with a plurality of first drain holes 5 in a ring. The inner cavity of the first drain hole 5 is provided with an anti-clogging component 6. The anti-clogging component 6 includes an inner liner 61 fixedly connected to the inner cavity of the drain pipe 4. The inner wall of the inner liner 61 is provided with a plurality of second drain holes 62 in a ring that communicate with the first drain holes 5. The top of the drain pipe 4 is fitted with an outer pipe 63. The top of the surface of the outer pipe 63 is fixedly connected with an interceptor plate 64. The surface of the interceptor plate 64 is provided with a plurality of overflow holes in a ring. The top of the outer pipe 63 is fixedly connected with a protective cover 65. The top of the protective cover 65 is conical. By setting the interceptor plate 64, foreign objects floating on the surface of the water are intercepted, thereby preventing foreign objects from entering the inner cavity of the drain pipe 4 and causing blockage. At the same time, with the cooperation of the protective cover 65, the top of the outer pipe 63 is shielded to prevent fallen leaves or other foreign objects from falling into the inner cavity of the outer pipe 63 and causing blockage.

[0024] Working principle: When using this utility model, the user glues the waterproof gasket 8 to the opening in the inner cavity of the gutter 1, and installs the mounting plate 3 along with the sealing ring 7 on the surface of the waterproof gasket 8. The mounting plate 3 is then installed and fixed using expansion bolts 9. At the same time, the outer connecting pipe 63 is fixedly installed on the top of the drain pipe 4 using tapping 10. During use, a small amount of water accumulated in the inner cavity of the gutter 1 enters the inner cavity of the drain pipe 4 through the first drain hole 5 for drainage. The first drain hole 5 allows for the initial filtration of foreign matter in the accumulated water before it enters the inner cavity of the drain pipe 4. When the accumulated water reaches between the inner liner pipe 61 and the drain pipe 4, the foreign objects in the water are filtered a second time through the second drain hole 62. The foreign objects are simultaneously trapped in the interlayer between the inner liner pipe 61 and the drain pipe 4. When the first drain hole 5 and the second drain hole 62 are blocked or the drainage efficiency is insufficient to generate water in the inner cavity of the gutter 1, the water level rises and reaches the level of the top of the drain pipe 4. At this time, the interceptor plate 64 intercepts the foreign objects floating on the surface of the water, and the water enters the inner cavity of the drain pipe 4 directly from the top, thereby enhancing the drainage capacity.

[0025] In summary, the roof gutter and anti-clogging drain structure of this building, through the setting of gutter 1, collects rainwater flowing down from the roof. With the cooperation of the pre-embedded drain pipe 2, drain pipe 4 and first drain hole 5, the rainwater is filtered and discharged for the first time. At the same time, with the cooperation of the anti-clogging component 6, the water can be discharged a second time according to the water depth in the inner cavity of gutter 1, thus achieving the purpose of effectively filtering drainage impurities and preventing drainage blockage.
