Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a sediment-proof gravity drainage rainwater bucket. Background Art

[0002] During the construction process, the rain gutter base needs to be installed and fixed before waterproofing. During the construction of the waterproof protective layer, the civil engineering profession is prone to flow concrete and other liquids mixed with mud and sand to the rain gutter, causing the pipes and rain gutter to be blocked. After the rain gutter is installed, the building roof and other parts are exposed to the sun, and the finished surface of the building is prone to sand return. After the outdoor dust settles and encounters rainfall, the mud and garbage on the roof surface are carried by rainwater to the rain gutter, which is easy to cause the rain gutter to be blocked.

[0003] The traditional anti-clogging method is to install a filter net in the rain gutter, but this solution cannot effectively isolate the mud and sand debris, and the filter net is easily clogged by garbage and debris, resulting in increased maintenance costs. It requires multiple cleanings and the filter net itself is easily corroded and damaged.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] In order to overcome the defects of the prior art, a silt-proof gravity drainage rainwater bucket is provided to solve the problem that the traditional rainwater bucket cannot separate the silt in the rainwater.

[0006] In order to achieve the above purpose, a silt-proof gravity drainage rainwater bucket is provided, comprising:

[0007] A base, wherein a sedimentation tank is formed on the base, wherein a through hole is vertically arranged and connected to the sedimentation tank, wherein a drainage pipe is passed through the through hole, and an upper pipe opening of the drainage pipe extends into the sedimentation tank;

[0008] A filter screen cover, which is detachably mounted on the upper pipe opening;

[0009] An annular protective component is mounted on the base, a gap is formed between the protective component and the upper part of the base, the filter screen is movably arranged in the inner ring hole of the protective component, a plurality of water guide channels are formed on the protective component, the two ends of the water guide channels respectively penetrate the outer ring surface and the inner ring surface of the protective component, and the elevation of the bottom hole wall of the water guide channel gradually decreases from the middle of the water guide channel to the two ends of the water guide channel.

[0010] Furthermore, the through hole is coaxially arranged with the sedimentation tank.

[0011] Furthermore, the wall of the sedimentation tank is arc-shaped.

[0012] Furthermore, the protective component includes a coaxially arranged upper ring plate and a lower ring plate, the lower ring plate is mounted on the base, the height of the upper surface of the lower ring plate gradually decreases from the middle of the lower ring plate toward the inner edge and outer edge of the lower ring plate, a plurality of support plates are connected between the upper ring plate and the lower ring plate, two adjacent support plates and the upper ring plate and the lower ring plate are enclosed to form the water guide channel, and the filter screen cover is movably arranged in the inner ring holes of the upper ring plate and the lower ring plate.

[0013] Furthermore, the outer side of the support plate is turned down to form a support portion extending to the bottom of the lower ring plate, and the base is supported by the support portion.

[0014] Furthermore, the cross section of the lower ring plate is arc-shaped.

[0015] The beneficial effect of the present invention is that, for the anti-silt gravity drainage rain gutter of the present invention, when the rainfall is small, the roof rainwater flows into the sedimentation tank through the 1 cm gap between the base and the protective component, and then the sediment in the sedimentation tank is precipitated, so that the precipitated rainwater is discharged into the drain pipe through the filter mesh cover, and finally discharged through the downpipe.

[0016] The anti-silt gravity drainage rainwater bucket of the present invention, when the rainfall is large, part of the roof rainwater falls into the sedimentation tank through the gap between the base and the protective component, and the rest of the roof rainwater enters the water filter screen through the water guide channel.

[0017] When the rainfall is heavy, rainwater flows through the gap and the water channel at the same time. The rainwater level is lower than the bottom side of the lower ring plate, and the sediment is blocked by the arch of the lower ring plate and enters the sedimentation tank from the gap. The water level is higher than the arch of the lower ring plate and flows into the sedimentation tank through the lower side of the lower ring plate. After the sediment is settled in the sedimentation tank, the separated rainwater is discharged into the downpipe through the filter screen and the drain pipe.

[0018] The anti-silt gravity drainage rainwater bucket of the present invention can collect and settle the silt flowing into the rainwater pipe at different rainfall amounts, thereby reducing the problems of clogging of the rainwater bucket and the pipe due to silt and garbage.

[0029] As a preferred embodiment, the base and the drain pipe are integrally formed. The wall of the sedimentation tank 10 is arc-shaped. The base and the drain pipe form an annular groove.

[0030] The filter screen cover 2 is detachably covered on the upper pipe opening. The filter screen cover is a stainless steel screen cover. The cover opening of the filter screen cover is arranged in a direction.

[0031] In this embodiment, the cover opening of the filter screen cover is connected to the upper pipe opening of the drain pipe through a connecting pipe, and the lower pipe opening of the connecting pipe is plugged or threadedly connected to the upper pipe opening of the drain pipe.

[0032] The protective component is in a circular shape as a whole. The protective component 4 is arranged around the outside of the filter screen. The protective component is mounted on the base 1. A gap 100 is formed between the protective component 4 and the upper part of the base 1. The filter screen 2 is movably arranged in the inner ring hole of the protective component 4. A plurality of water guide channels are formed on the protective component 4. The water guide channels are arranged along the radial direction of the protective component. The two ends of the water guide channel of the protective component pass through the outer ring surface and the inner ring surface of the protective component 4 respectively.

[0033] The elevation of the bottom hole wall of the water guide channel gradually decreases from the middle of the water guide channel to the two ends of the water guide channel.

[0034] As a preferred implementation, the bottom hole wall of the water-conducting channel is arc-shaped.

[0035] See also Figure 4 As shown, the protection assembly 4 includes an upper ring plate 41 and a lower ring plate 42 which are coaxially arranged.

[0036] In this embodiment, the upper ring plate and the lower ring plate are matched in shape and size. The upper ring plate is arranged above the lower ring plate.

[0037] The lower ring plate 42 is mounted on the base 1. The gap is formed between the lower ring plate and the flange of the base. The height of the upper surface of the lower ring plate 42 gradually decreases from the middle of the lower ring plate 42 to the inner edge and outer edge of the lower ring plate 42.

[0038] In this embodiment, the upper ring plate is a flat plate, and the cross section of the lower ring plate 42 is arc-shaped.

[0039] A plurality of support plates 43 are connected between the upper ring plate 41 and the lower ring plate 42. Two adjacent support plates 43, the upper ring plate 41 and the lower ring plate 42 enclose a water channel. The filter screen cover 2 is movably disposed in the inner ring holes of the upper ring plate 41 and the lower ring plate 42.

[0040] The outer side of the support plate 43 is turned down to form a support portion 431 extending to the bottom of the lower ring plate 42. The base 1 is supported by the support portion 431. The protection component is mounted on the flange of the base through the support portion.

[0041] In this embodiment, the protection assembly is coaxially arranged with the sedimentation tank of the base, and the outer diameter of the lower ring plate is adapted to the outer diameter of the sedimentation tank.

[0042] When in use, select a rain gutter of matching size for the drainage pipe according to the pipe specifications of the downpipe. After the construction surface is completed, install the filter screen cover and protective components on the base. After the sediment collected in the sedimentation tank of the base settles to a certain extent, remove the filter screen cover and protective components and clean the sediment in the sedimentation tank.

The height of the support part of the protective component is 1 cm.

[0044] The anti-silt gravity drainage rain gutter of the present invention, when the rainfall is small, the roof rainwater flows into the sedimentation tank through the 1 cm gap between the base and the protective component, and then the sediment is precipitated in the sedimentation tank, so that the precipitated rainwater is discharged into the drainage pipe through the filter screen cover, and finally discharged through the downpipe.

[0045] The anti-silt gravity drainage rainwater bucket of the present invention, when the rainfall is large, part of the roof rainwater falls into the sedimentation tank through the gap between the base and the protective component, and the rest of the roof rainwater enters the water filter screen through the water guide channel.

[0046] When the rainfall is heavy, rainwater flows through the gap and the water channel at the same time. The rainwater level is lower than the sediment on the bottom side of the lower ring plate (such as Figure 2 The hollow arrow at the bottom of the figure indicates that the water flows into the sedimentation tank from the gap through the arch of the lower ring plate. The water flows through the lower ring plate obliquely below the arch of the lower ring plate and flows into the sedimentation tank (as shown in the figure). Figure 2 After the sediment is settled in the sedimentation tank, the separated rainwater is discharged into the downpipe through the filter screen and the drain pipe.

[0047] The anti-silt gravity drainage rainwater bucket of the present invention can collect and settle the silt flowing into the rainwater pipe at different rainfall amounts, thereby reducing the problems of clogging of the rainwater bucket and the pipe due to silt and garbage.
