Description

Technical Field

[0001] This application relates to the field of rainwater drainage technology, and in particular to a novel siphon rainwater hopper for sponge cities. Background Technology

[0002] In the construction of sponge cities, efficient rainwater drainage systems are of great significance for reducing urban flooding and protecting the urban ecological environment. Rainwater hoppers are the core components of roof drainage systems, located at the junction of gutters and rainwater pipes, and are responsible for rainwater collection, rectification, filtration and diversion. Their design directly affects drainage efficiency and building safety.

[0003] Existing traditional rainwater hoppers have some problems in the drainage process, such as low drainage efficiency, easy formation of eddies leading to air entrainment, and the need for a relatively deep water depth in front of the hopper to form full pipe flow. These problems limit their application effect in sponge city construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a novel siphon rainwater hopper for sponge cities, which overcomes the deficiencies of existing technologies and aims to solve some problems in the drainage process of existing traditional rainwater hoppers, such as low drainage efficiency, easy formation of eddies leading to air entrainment, and the need for a deep water depth in front of the hopper to form full pipe flow. These problems limit their application effect in sponge city construction.

[0005] To achieve the above objectives, this application provides the following technical solution: a novel siphon rainwater hopper for sponge cities, comprising an annular frame, an inlet grid inside the annular frame, a rainwater hopper body below the annular frame, a siphon pipe at the bottom of the rainwater hopper body, a multi-stage diversion device and an anti-vortex device inside the rainwater hopper body, the multi-stage diversion device being located above the anti-vortex device, the multi-stage diversion device comprising multiple sets of parallel diversion plates, the outer walls of the multiple sets of parallel diversion plates being fixedly connected to the inner wall of the rainwater hopper body, the multiple sets of parallel diversion plates being arranged parallel to each other, the size of the multiple sets of parallel diversion plates matching the inner wall of the rainwater hopper body, and multiple diversion holes being opened inside the multiple sets of parallel diversion plates; the anti-vortex device comprising an anti-vortex net, the size of the anti-vortex net corresponding to the rainwater hopper body.

[0006] By adopting the above technical solution and setting up a ring frame, during use, the water flowing from the roof flows directly into the interior of the rainwater hopper through the ring frame. After passing through a multi-stage diversion device, the rainwater is evenly dispersed into multiple fine streams. Then, as it continues downward through the anti-vortex device, the flow structure of the water is disrupted, preventing air entrainment and ensuring rapid formation of full-pipe flow at extremely low water depths. Then, it is directly discharged into the interior of the drain pipe through a siphon pipe. In this way, full-pipe flow can be achieved at shallower water depths in front of the hopper during use, effectively reducing the water accumulation depth in the roof, gutters, and eaves, reducing the roof load, reducing the risk of leakage, improving the safety and service life of the building, and having strong adaptability: it is suitable for various scenarios in sponge city construction, such as concrete roofs, metal roofs, and wooden roofs.

[0007] As a preferred technical solution of this application, a cleaning pipe is provided below the bend of the siphon pipe, the cleaning pipe is interconnected with the siphon pipe, and a baffle is provided at the bottom of the cleaning pipe.

[0008] By adopting the above technical solution and setting up a cleaning pipe, rainwater deposits can be quickly cleaned during use, preventing fine impurities from accumulating and affecting drainage efficiency, and improving stability during use.

[0010] By adopting the above technical solution and setting up a partition plate, rainwater entering the interior of the annular frame can be further diverted during use. At the same time, it can effectively prevent larger debris from entering the interior of the rainwater hopper body, thus effectively reducing the filtration efficiency of the annular frame.

[0011] As a preferred technical solution of this application, multiple sets of threaded hole plates are provided at the bottom of the annular frame and above the rainwater hopper body, and mounting bolts are provided inside the multiple sets of corresponding threaded hole plates.

[0012] By adopting the above technical solution and setting the threaded perforated plate, a quick connection between the annular frame and the rainwater hopper body can be achieved during use, making disassembly and installation more convenient during subsequent maintenance and improving the practicality of the device.

[0013] As a preferred technical solution of this application, the aperture of the anti-vortex mesh is about 5 to 10 mm, the aperture of the diversion hole is about 5 to 10 mm, and the spacing between the multiple sets of parallel diversion plates is about 10 to 20 mm.

[0014] By adopting the above technical solution, and by limiting the hole spacing of the anti-vortex mesh and the spacing of multiple sets of parallel diverter plates, the uniform dispersion effect of water flow can be further improved, and the performance of the device can be further enhanced.

[0015] As a preferred technical solution of this application, a top plate is provided above each of the multiple sets of partition plates, and the top of the top plate is set as an inclined surface.

[0016] By adopting the above technical solution and setting a top plate, the top of the device can be shielded during use to prevent leaves and other objects from falling directly onto the device.

[0017] As a preferred technical solution of this application, a filter screen is provided at the bottom of the annular frame, and the filter screen is located at the bottom of the water inlet grille.

[0018] By adopting the above technical solution and setting up a filter screen, the filtration effect can be further improved during use, further preventing debris from entering the interior of the rainwater hopper and ensuring stability during use.

[0019] As a preferred technical solution of this application, a protective net is provided on the outer side of each of the multiple sets of partition plates, and the protective net is arranged in a ring.

[0020] By adopting the above technical solution and setting up a protective net, the external shielding of multiple sets of partitions can be achieved during use, further improving the isolation effect and enhancing the stability of the device during use.

[0021] The beneficial effects of this application are: 1. By setting up a ring frame, during use, the water flowing from the roof flows directly into the interior of the rainwater hopper through the ring frame. After passing through a multi-stage diversion device, the rainwater is evenly dispersed into multiple fine streams. Then, as it continues downward through the anti-vortex device, the flow structure of the water is disrupted, preventing air entrainment and ensuring rapid full-pipe flow at extremely low water depths. Then, it is directly discharged into the interior of the drain pipe through a siphon pipe. In this way, full-pipe flow can be achieved at shallower water depths in front of the hopper, effectively reducing the water accumulation depth in the roof, gutters, and eaves, reducing the roof load, reducing the risk of leakage, improving the safety and service life of the building, and having strong adaptability: suitable for various scenarios in sponge city construction, such as concrete roofs, metal roofs, and wooden roofs.

The outer walls of the multiple sets of parallel diversion plates 401 are fixedly connected to the inner wall of the rainwater hopper body 2. The multiple sets of parallel diversion plates 401 are arranged in parallel to each other, and their sizes match the inner walls of the rainwater hopper body 2. The interior of each set of parallel diversion plates 401 has multiple diversion holes 402. The anti-vortex device 5 includes an anti-vortex net 501, the size of which corresponds to the size of the rainwater hopper body 2. Multiple sets of partition plates 7 are arranged above the annular frame 1, and the spacing between the multiple sets of partition plates 7 is the same. A fixing groove 105 is provided above the annular frame 1, and a connecting block 701 is provided at the bottom of the partition plate 7. The connecting block 701 is inserted into the interior of the fixing groove 105.

[0027] By setting up the annular frame 1, during use, the rainwater from the roof flows directly into the interior of the rainwater hopper body 2 through the annular frame 1. After passing through the multi-stage diversion device 4, the rainwater is evenly dispersed into multiple fine streams. Then, when it continues downward through the anti-vortex device 5, the flow structure of the water is disrupted, which can prevent air from being entrained and ensure that a full pipe flow is quickly formed at extremely low water depths. Then, it is directly discharged into the interior of the drain pipe through the siphon pipe 3. In this way, during use, a full pipe flow can be achieved at a shallower water depth in front of the hopper, effectively reducing the water accumulation depth in the roof, gutters, eaves, etc., reducing the roof load, reducing the risk of leakage, improving the safety and service life of the building, and having strong adaptability: it is suitable for various scenarios in sponge city construction, such as concrete roofs, metal roofs, wooden roofs, etc. By setting up the partition plate 7, during use, the rainwater entering the interior of the annular frame 1 can be further diverted, while effectively preventing larger debris from entering the interior of the rainwater hopper body 2, effectively reducing the filtration efficiency of the annular frame 1.

[0028] Reference Figure 1-4 A cleaning pipe 301 is installed below the bend of the siphon pipe 3, and the cleaning pipe 301 is interconnected with the siphon pipe 3. A baffle 302 is installed at the bottom of the cleaning pipe 301. Multiple sets of threaded hole plates 102 are installed at the bottom of the annular frame 1 and above the rainwater hopper body 2. Each set of corresponding threaded hole plates 102 has a mounting bolt 104 installed inside. A top plate 8 is installed above each set of partition plates 7, and the top of the top plate 8 is sloped. By setting up the cleaning pipe 301, rainwater can be quickly cleaned at the sedimentation point during use, preventing fine impurities from forming sediment that affects drainage efficiency and improving stability during use. By setting up the threaded hole plates 102, the annular frame 1 and the rainwater hopper body 2 can be quickly connected during use, making disassembly and installation more convenient during subsequent maintenance and improving the practicality of the device. By setting up the top plate 8, the top of the device can be shielded during use to prevent leaves and other objects from falling directly onto the top of the device.

By limiting the aperture spacing of the anti-vortex mesh 501 and the spacing between the multiple sets of parallel diversion plates 401, the uniform dispersion effect of the water flow can be further improved, and the performance of the device can be further enhanced. A filter screen 103 is provided at the bottom of the annular frame 1, and the filter screen 103 is located at the bottom of the inlet grille 101. By setting the filter screen 103, the filtration effect can be further improved during use, and debris can be further prevented from entering the interior of the rainwater hopper body 2, ensuring stability during use. A protective net 702 is provided on the outer side of each set of partition plates 7, and the protective net 702 is arranged in an annular shape. By setting the protective net 702, the exterior of the multiple sets of partition plates 7 can be blocked during use, further improving the isolation effect and enhancing the stability of the device during use.

[0030] Working principle: By setting up a ring frame 1, during use, the water flow from the roof flows directly into the interior of the rainwater hopper body 2 through the ring frame 1. After passing through the multi-stage diversion device 4, the rainwater is evenly dispersed into multiple fine streams. Then, when it continues to flow downward through the anti-vortex device 5, the flow structure of the water flow is disrupted, which can prevent air from being entrained and ensure that a full pipe flow is quickly formed at extremely low water depths. Then, it is directly discharged into the interior of the drain pipe through the siphon pipe 3. In this way, during use, a full pipe flow can be achieved at a shallower water depth in front of the hopper, effectively reducing the water accumulation depth in the roof, gutters, eaves, etc., reducing the roof load, reducing the water accumulation depth on the roof, reducing the risk of leakage, improving the safety and service life of the building, and having strong adaptability: it is suitable for various scenarios in sponge city construction, such as concrete roofs, metal roofs, wooden roofs, etc. By setting up a cleaning pipe 301, during use, rainwater accumulation points can be quickly cleaned to prevent fine impurities inside from forming a certain amount of sediment that affects drainage efficiency and improves the stability during use. By setting the partition plate 7, rainwater entering the interior of the annular frame 1 can be further diverted during use, while effectively preventing larger debris from entering the interior of the rainwater hopper body 2, thus effectively reducing the filtration efficiency of the annular frame 1. By setting the threaded perforated plate 102, a quick connection between the annular frame 1 and the rainwater hopper body 2 can be achieved during use, making disassembly and installation more convenient during subsequent maintenance and improving the practicality of the device. Meanwhile, by limiting the hole spacing of the anti-vortex net 501 and the spacing of the multiple sets of parallel diverter plates 401, the uniform dispersion effect of the water flow can be further improved, and the performance of the device can be further enhanced. In addition, by setting the top plate 8, the top of the device can be shielded during use to prevent leaves and other objects from falling directly onto the device; by setting the filter screen 103, the filtration effect can be further improved during use, further preventing debris from entering the interior of the rainwater hopper body 2 and ensuring stability during use; by setting the protective net 702, the exterior of the multiple sets of partition plates 7 can be shielded during use, further improving the isolation effect and enhancing the stability of the device during use.
