Description

Technical Field

[0001] The utility model relates to the field of rainwater discharge, in particular to a siphonic rainwater hopper. Background Technique

[0002] The siphonic rainwater hopper is an important part of the rainwater discharge system to maintain the drain pipe in a siphonic state. The siphonic rainwater hopper has a strong anti-vortex function, which can well prevent air from being brought into the whole system through the water flow at the entrance of the rainwater hopper, and when the water level in front of the hopper rises to a certain extent, a water seal is formed to completely block the entry of air. The main structure of the siphonic rainwater hopper includes a rainwater chassis, a top cover, a fairing and an anti-vortex device. During installation, the chassis contacts the gutter or the roof, and rainwater enters the inside of the rainwater hopper through the fairing. For example, a siphonic rainwater hopper made of anti-ultraviolet plastic disclosed in patent application No. CN202320670561.7, after the installation of the chassis and the gutter is completed, the part above the chassis is exposed to the outside. A lot of debris will be generated in the gutter during long-term accumulation, and the debris is easy to enter the inside of the rainwater hopper through the fairing, causing blockage. Although the fairing plates on the fairing can block larger debris, it is difficult to block small debris. Especially when there is wind, the debris will enter the inside of the rainwater hopper from the fairing following the wind, and long-term accumulation will cause blockage inside the rainwater hopper, which is more troublesome to clean. Patent application No. 202020535333.5 discloses a rainwater discharge system for buildings and a siphonic rainwater hopper, which discloses that a perforation is provided in the middle of the water collecting tray, a cavity communicating with the perforation is provided in the middle of the hopper body, a pipe body is provided in the middle of the lower end of the cavity, an inlet hole is provided in the middle and upper part of the side surface of the pipe body, and a sedimentation space is formed between the pipe body and the cavity. Although this structure can effectively reduce the solids in the rainwater and avoid pipe blockage by arranging a pipe body in the cavity of the hopper body to form a sedimentation space and providing an inlet hole on the pipe body; however, with long-term use, the debris will gradually fill the sedimentation space, thereby blocking the inlet hole and causing rainwater discharge to be blocked. At the same time, this structure for filtering debris inside needs to disassemble the whole structure during cleaning, which is more troublesome to clean. Therefore, this application proposes a siphonic rainwater hopper to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Combined with Figures 1 to 6 To illustrate this embodiment, this embodiment provides a siphon rainwater bucket, which includes a chassis 1, a top plate 2 and a rain pipe joint 3 arranged coaxially. On one surface of the top plate 2 close to the chassis 1, there are several rectifying plates 4 distributed in an annular array. On the other surface of the top plate 2, there are several flow guiding plates 5 distributed in an annular array. The rectifying plates 4 are attached to the upper surface of the chassis 1. A through groove 6 is provided in the middle of the chassis 1. The rain pipe joint 3 is connected to the chassis 1. A flow rate adjusting ring plate 8 is provided between the chassis 1 and the top plate 2. The flow rate adjusting ring plate 8 is elastically connected to the top plate 2 and moves towards the top plate 2 after being subjected to a force. The flow rate adjusting ring plate 8 surrounds the through groove 6 in a circle. On the side of the flow rate adjusting ring plate 8 away from the through groove 6, there is an upwardly inclined force receiving ring 9. A flexible shield 10 is fixedly connected to the bottom of the flow rate adjusting ring plate 8.

[0025] There are several light columns 7 distributed in an annular array between the chassis 1 and the top plate 2. The flow rate adjusting ring plate 8 is slidably connected to the light columns 7. The flow rate adjusting ring plate 8 and the top plate 2 are connected by a spring 16. The spring 16 is sleeved outside the light column 7. A rust-proof layer can be wrapped outside the spring 16. The inclination angle of the force receiving ring 9 is 45 - 60°. When discharging rainwater, the rainwater exerts a pressure on the force receiving ring 9, causing the force receiving ring 9 to drive the flow rate adjusting ring plate 8 to squeeze the spring 16 upward.

[0026] In this example, the number of rectifying plates 4 is twice that of the flow guiding plates 5, and the part where the rectifying plates 4 and the flow guiding plates 5 correspond one by one is an integral structure. And a connecting ring 11 is provided above the top plate 2. The connecting ring 11 is fixedly connected to the rectifying plates 4. The connecting ring 11 is used to connect the rectifying plates 4 together to improve stability.

[0027] One end of the rain pipe joint 3 is provided with a flange 12. The flange 12 is provided with threaded holes. On the side surface of the flange 12 facing away from the chassis 1, there is a fixing ring 13. The chassis 1 and the fixing ring 13 are connected by short bolts 14. The top plate 2 and the fixing ring 13 are connected by long bolts 15 passing through the chassis 1. The short bolts 14 and the long bolts 15 are on the same circumference and are staggeredly distributed. The chassis 1, the top plate 2 and the rain pipe joint 3 are fixedly connected together by the long bolts 15 and the short bolts 14.

[0028] The flexible baffle 10 is a brush surrounding the bottom of the flow regulation ring plate 8. Adopting a brush structure, when there is light rain, the rainwater can directly drain out through the gaps of the brush. As the rainfall increases, the brush is washed and deformed inward. When the rainfall continues to increase, a force is applied to the force-bearing ring 9 to drive the flow regulation ring to move upward.

[0029] In the middle of the top plate 2, there is a pressure plate 17. The pressure plate 17 is slidably connected to the top plate 2. Specifically, a through cavity is provided in the middle of the top plate 2. A ring plate 18 is fixedly connected to the bottom surface of the top plate 2. A limiting ring 19 is fixedly connected to the lower end of the ring plate 18. The ring plate 18 is slidably connected to the through cavity. Exhaust grooves 20 are circumferentially distributed at one end of the side wall of the ring plate 18 close to the pressure plate 17. Buffer pads 21 are provided on the opposite sides of the pressure plate 17 and the ring plate 18. When the rainwater submerges the top plate 2, during the drainage process, the air in the rainwater pipe can push open the pressure plate 17 to discharge the air from the exhaust grooves 20, further improving the exhaust efficiency. And an exhaust passage 22 that connects the bottom surface and the side surface is provided on the pressure plate 17. When the pressure in the rainwater pipe is not sufficient to push open the pressure plate 17, the air can be discharged using the exhaust passage 22.

[0030] As another structure, the part of the long bolt 15 between the top plate 2 and the bottom plate 1 is smooth. The long bolt 15 is used to replace the smooth rod, so that the flow regulation ring plate 8 is slidably connected to the long bolt 15. In this way, the use of the smooth rod is reduced, and the flow regulation ring plate 8 is connected to the top plate 2 through a spring 16, and the rest remains unchanged.

[0031] The working principle of the present utility model is as follows: A flow regulation ring plate 8 is arranged between the bottom plate 1 and the top plate 2. When there is no rainwater discharge, the flow regulation ring plate 8 slides down to fit with the bottom plate 1 and cooperates with the force-bearing ring 9 to seal the lower part of the flow channel between the rectifying plates 4, which can effectively reduce the entry of sundries into the rainwater funnel. When discharging rainwater, the water pressure of the accumulated water acts on the force-bearing ring 9, causing the flow regulation disk to slide upward, opening the flow channel between the rectifying plates 4, and the rainwater enters the rainwater funnel and flows into the rain pipe joint 3 through the through groove 6; it can prevent external sundries from entering the interior when the rainwater funnel is not draining, causing blockage, and at the same time block the sundries outside the rainwater funnel. The cleaning can be achieved without disassembling the rainwater funnel structure, which is convenient, fast, efficient, and reduces the labor intensity of workers.
