Abstract
Description
Technical Field
[0001] This utility model relates to the field of water guide channel technology, and in particular to the structure of anti-siltation and anti-clogging gutter water guide channel. Background Technology
[0002] In building drainage systems, gutters are a key component for collecting rainwater from roofs, and their drainage performance directly affects the safety and lifespan of the building. Traditional gutter drainage systems commonly face problems such as frequent clogging and insufficient drainage efficiency during long-term use, causing numerous challenges for building maintenance.
[0003] The existing gutter drainage system has a relatively simple inlet design, mostly using a single-diameter inlet, which makes it difficult to meet the drainage needs under different water levels. When heavy rainfall causes a sudden rise in water level, insufficient water intake capacity can easily lead to rainwater accumulation in the gutter. This can not only cause roof leaks, but also place additional load on the building structure due to the increased weight of the accumulated water, posing a safety hazard. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides an anti-clogging gutter drainage channel structure.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] The anti-clogging gutter drainage channel structure includes: a mounting base and a cylindrical tube fixedly mounted on the mounting base. The mounting base is circular and the mounting base and the cylindrical tube are arranged coaxially. A conical head is fixedly mounted on the upper end of the cylindrical tube.
[0007] Preferably, the cylinder wall has a plurality of first rectangular holes arranged in a ring array.
[0008] Preferably, the cylinder wall is provided with a plurality of second rectangular holes arranged in a ring array, and the plurality of second rectangular holes are all located above the plurality of first rectangular holes.
[0009] Preferably, the top of the conical head has an air inlet.
[0010] Preferably, the conical head has multiple guide holes arranged in a ring array on its inclined surface.
[0011] Preferably, the design of the conical head keeps the air inlet above the water level.
[0012] Preferably, the design of the first rectangular hole and the second rectangular hole increases the water inlet and drainage area.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By designing the upper and lower distribution of the first and second rectangular holes, combined with the guide holes on the inclined surface of the conical head, the water inlet and outlet area is increased, which can meet the drainage needs at low water levels and drain water quickly at high water levels, effectively improving drainage efficiency.
[0015] 2. The first rectangular hole and the guide hole can play a preliminary filtering role for larger volume impurities, reducing the impurities entering the cylinder; at the same time, the air inlet can balance the air pressure, avoid negative pressure affecting the water flow, ensure the stable operation of the entire drainage system, and reduce the probability of clogging.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Reference Figure 1-3 The anti-clogging gutter drainage channel structure includes a mounting base 1 and a cylindrical tube 2 fixedly mounted on the mounting base 1. The mounting base 1 is circular and made of high-strength, corrosion-resistant material, which not only provides stable support for the entire device but also fits tightly against the bottom of the gutter, preventing leakage or displacement due to insecure installation. The mounting base 1 and the cylindrical tube 2 are arranged coaxially. This design ensures that the water flow is evenly stressed when entering the cylindrical tube 2, avoiding localized water flow turbulence caused by eccentricity, thereby reducing the accumulation of impurities in specific locations.
[0024] As the main channel for water flow, the structural design of cylinder 2 is crucial to its drainage effect. Multiple first rectangular holes 3 are arranged in a ring array on the cylinder wall of cylinder 2. The dimensions of these first rectangular holes 3 are precisely calculated to ensure a large water flow rate while also providing preliminary filtration of larger impurities, preventing them from entering the cylinder and causing blockages. Simultaneously, the ring array layout ensures more uniform water intake, avoiding overflow problems caused by excessive localized water intake.
[0025] To further enhance drainage capacity, multiple second rectangular holes 4 are arranged in a ring array on the cylinder wall of the cylinder 2, and all of the second rectangular holes 4 are located above the multiple first rectangular holes 3. This vertically distributed design fully considers the drainage needs under different water levels. When the water level is low, water mainly enters through the first rectangular holes 3; while when the water level is high, the second rectangular holes 4 can participate in water intake in a timely manner, greatly improving drainage efficiency.
[0026] A conical head 5 is fixedly installed at the upper end of the cylinder 2. The design of the conical head 5 has multiple advantages. First, its conical structure can guide the falling rainwater, allowing it to flow more smoothly to the side wall of the cylinder 2, reducing splashing and energy loss caused by rainwater directly impacting the top of the cylinder 2. Second, the top of the conical head 5 has an air inlet 6, which can effectively balance the air pressure inside and outside the cylinder 2, preventing negative pressure from forming due to low internal air pressure during drainage, which would affect the normal flow of water. Moreover, through the ingenious design of the conical head 5, it can be ensured that the air inlet 6 is always above the water level, ensuring smooth air entry even during peak drainage periods, maintaining the air pressure balance of the drainage system.
[0027] Furthermore, multiple guide holes 7 are arranged in a ring array on the inclined surface of the conical head 5. These guide holes 7 can further divert rainwater, allowing some rainwater to directly enter the cylinder 2 through the guide holes 7, thus increasing the water inlet pathway. At the same time, the guide holes 7 can also play a certain filtering role for rainwater, reducing the probability of larger impurities entering the interior of the cylinder 2.
[0028] In summary, the design of the first rectangular hole 3 and the second rectangular hole 4 increases the water inlet and drainage area. Combined with the conical head 5 and its air inlet 6 and guide hole 7, the entire anti-clogging gutter drainage channel structure performs excellently in terms of drainage efficiency, anti-clogging ability and air pressure balance, and can effectively cope with various complex drainage situations.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
