Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a rainwater hopper with self-cleaning ability, mainly used in roof rainwater drainage systems. Background Technology

[0002] In existing rainwater systems, a complete rainwater system consists of rainwater hoppers, drainage pipes, and supporting structures. Among these, the rainwater hopper is a crucial component. It is usually installed at the inlet where rainwater enters the rainwater pipes from the roof gutters. Its main design purpose is to quickly drain rainwater and snowmelt from the roof, while preventing the formation of excessive eddies, stabilizing the water level, and reducing air entrainment.

[0003] In practical applications, especially for siphon systems, rainwater hoppers require regular maintenance and inspection, primarily because roof rainwater hoppers can become clogged with foreign objects. Once foreign objects enter the rainwater system, causing blockages, rainwater discharge may be delayed or reduced in efficiency, leading to rainwater overflow and affecting the indoor environment.

[0004] Based on practical application analysis, common debris clogging rainwater drains includes, but is not limited to, plastic bags, fallen leaves, and silt. Small particles are flushed away by rainwater and discharged through the drainage system, but larger particles or viscous substances cannot be removed promptly, posing a risk of clogging the drain pipes. Therefore, a rainwater drain with self-cleaning capabilities is needed to solve this problem. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a rainwater hopper with self-cleaning capabilities, solving the technical problem that rainwater hoppers are prone to clogging drainage pipes due to foreign objects during use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rainwater hopper with self-cleaning capability includes a rainwater hopper body and a self-cleaning component. The rainwater hopper body includes a top rainwater hopper cap, a middle hopper base, and a lower drain pipe. The self-cleaning component includes an arc-shaped support rib, a rotating hub, a transmission rod, and a self-driven rotating fan. The arc-shaped support rib and the rotating hub are located on the top of the self-cleaning component. One end of the arc-shaped support rib is connected to the rotating hub, and the other end is fixedly connected to the upper end face of the hopper base. A bearing assembly is installed inside the rotating hub. The upper end of the transmission rod is connected to the inner ring of the bearing assembly, and the lower end of the transmission rod is equipped with a self-driven rotating fan. The blades of the self-driven rotating fan are set with an inclined arc.

[0008] In a further technical solution, the rotating hub is located above the top of the rainwater hopper cap, and a through hole is provided at the corresponding position of the rainwater hopper cap. The transmission rod passes through the through hole, and both ends of the transmission rod are connected to the bearing assembly and the self-driven rotating fan, respectively.

[0009] In a further technical solution, the rainwater hopper cap is connected and installed on the upper end face of the hopper body base, and the lower drain pipe is connected and installed on the lower end face of the hopper body base.

[0010] In a further technical solution, the rainwater hopper cap has rectifier grilles arranged at predetermined intervals along the circumference.

[0011] In a further technical solution, the bucket base has an internal cavity, and the self-driven rotating fan is disposed within the cavity.

[0012] In a further technical solution, the blades of the self-driven rotating fan are positioned close to the inner wall of the cavity of the bucket base.

[0013] The present invention adds a self-cleaning component to the existing rainwater hopper. The rapidly rotating blades remove or crush foreign objects, increase flowability, facilitate the discharge of foreign objects, and thus reduce the risk of drainage pipe blockage.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-5 As shown, the present invention provides a rainwater hopper with self-cleaning capability, comprising a rainwater hopper body and a self-cleaning component. The rainwater hopper body includes a top rainwater hopper cap 1, a middle hopper body base 2, and a lower drain pipe 3. The rainwater hopper cap 1 is connected to the upper end face of the hopper body base 2, and the lower drain pipe 3 is connected to the lower end face of the hopper body base 2.

[0022] The self-cleaning component includes an arc-shaped support rib 4, a rotating hub 5, a transmission rod 6, and a self-driven rotating fan 7. The arc-shaped support rib 4 and the rotating hub 5 are located on the top of the self-cleaning component. One end of the arc-shaped support rib 4 is connected to the rotating hub 5, and the other end is fixedly connected to the upper end face of the bucket base 2. A bearing assembly is installed inside the rotating hub 5. The upper end of the transmission rod 6 is connected to the inner ring of the bearing assembly. The lower end of the transmission rod 6 is equipped with a self-driven rotating fan 7, which is a self-driven foreign object destroyer. The blades of the self-driven rotating fan 7 are set with an inclined arc. During operation, the rotation action destroys foreign objects.

[0023] During installation, the rotating hub 5 is set above the top of the rainwater hopper cap 1, and the rainwater hopper cap 1 is provided with a through hole 11 at the corresponding position. The transmission rod 6 is set through the through hole 11, and the two ends of the transmission rod 6 are respectively connected to the bearing assembly and the self-driven rotating fan 7.

[0024] The rainwater hopper cap 1 has rectifier grille bars 12 arranged at predetermined intervals along the circumference. The hopper base 2 has a cavity inside, and the self-driven rotating fan 7 is disposed in the cavity.

[0025] The blades of the self-driven rotary fan 7 are positioned close to the inner wall of the cavity of the bucket base 2. The blade tips are positioned as close as possible to the inner wall of the cavity without affecting blade rotation.

[0026] This invention adds a self-cleaning component (self-driven foreign object destroyer) to the existing rainwater hopper. The self-driven foreign object destroyer has an arc-shaped fan blade. Because the fan blade has a certain curvature, when rainwater enters, the force of the rainwater can drive the blade to rotate. As the rainwater is driven by gravity, it will accelerate its fall. The upper part of the rainwater system will be sucked in or a certain negative pressure will be formed, which will drive the blade to rotate faster. When foreign objects enter the rainwater system, the rapidly rotating blades will remove or break up the foreign objects, increase the flow, facilitate the discharge of foreign objects, and thus reduce the risk of drainage pipe blockage.

[0027] It should be noted that the rainwater hopper body involved in this utility model can be a conventional rainwater hopper, including the Type 87 rainwater hopper, siphon rainwater hopper, gravity rainwater hopper, etc. The rainwater hopper with self-cleaning ability of this utility model is particularly suitable for situations with relatively heavy rainfall. In such cases, foreign objects such as plastic bags, fallen leaves, and mud can easily enter the rainwater hopper system, and the high-speed rotation of the blades achieves the self-cleaning function, increasing the flow.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
