Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a sand-proof gravity drainage rainwater hopper. BACKGROUND

[0002] In the process of building construction, the rainwater hopper base needs to be installed and fixed before waterproof construction. During the construction process of the waterproof protection layer, the civil engineering professional is easy to flow the mixed mud and sand liquid such as concrete to the rainwater hopper part, causing the pipe and rainwater hopper to be blocked. After the installation of the rainwater hopper is completed, the building roof and other parts are easy to cause the sand to return after being exposed to the sun, and the mud and sand garbage on the surface of the roof is easy to flow to the rainwater hopper by rainwater, which is easy to cause the rainwater hopper to be blocked.

[0003] The traditional anti-blocking method is to install a filter screen at the rainwater hopper part, but this scheme cannot effectively isolate the mud and sand from the rainwater hopper, and the filter screen is easy to be blocked by garbage, resulting in increased maintenance cost, the need for multiple cleaning, and the filter screen itself is easy to rust and break.

[0004] The information disclosed in this BACKGROUND section is only for the purpose of increasing the understanding of the background of the present application and should not be regarded as an acknowledgment or any form of suggestion that this information forms prior art that is publicly known. SUMMARY

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

[0006] In order to achieve the above-mentioned purpose, a sand-proof gravity drainage rainwater hopper is provided, which comprises:

[0007] A base is formed with a sediment tank, the base is formed with a vertical through hole communicating with the sediment tank, a drainage pipe is arranged in the through hole, and the upper pipe opening of the drainage pipe extends into the sediment tank;

[0008] A filter screen cover is detachably arranged on the upper pipe opening;

[0009] A protective assembly in the form of a ring is arranged on the base, a gap is formed between the protective assembly and the upper part of the base, the filter screen cover is movably arranged in the inner ring hole of the protective assembly, a plurality of water guide holes are formed on the protective assembly, the two ends of the water guide hole respectively penetrate the outer ring surface and the inner ring surface of the protective assembly, and the bottom hole wall of the water guide hole gradually decreases from the middle part of the water guide hole to the two ends of the water guide hole.

[0010] Further, the through hole and the sediment tank are coaxially arranged.

[0011] Further, the tank wall of the sediment tank is arc-shaped.

[0012] Further, the protection assembly comprises an upper ring plate and a lower ring plate arranged coaxially, the lower ring plate is arranged on the base, the height of the upper surface of the lower ring plate gradually decreases from the middle part of the lower ring plate to the inner edge and the 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 form the water guide hole, and the filter screen cover is movably arranged in the inner ring hole of the upper ring plate and the lower ring plate.

[0013] Further, the outer side of the support plate is downwardly turned to form a support part extending to the lower side of the lower ring plate, and the base is supported on the support part.

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

[0015] The beneficial effects of the present application are that, when the rainfall is small, the roof rainwater flows into the sediment tank through the 1cm gap between the base and the protection assembly, and then the sediment is precipitated in the sediment tank, so that the precipitated rainwater is discharged into the drain pipe through the filter screen cover, and finally is discharged through the downpipe.

[0016] When the rainfall is large, part of the roof rainwater falls into the sediment tank through the gap between the base and the protection assembly, and the remaining part of the roof rainwater enters the filter screen cover through the water guide hole.

[0017] When the rainfall is large, the rainwater flows through the gap and the water guide hole at the same time. The part of the rainwater whose liquid surface is lower than the lower side of the lower ring plate is blocked by the vaulted part of the lower ring plate and enters the sediment tank from the gap. The part of the rainwater whose liquid surface is higher than the vaulted part of the lower ring plate flows into the sediment tank through the lower side of the lower ring plate, and the sediment is precipitated in the sediment tank. The separated rainwater is discharged into the downpipe through the filter screen cover and the drain pipe.

[0018] The anti-sediment gravity drainage rainwater bucket of the present application can collect and precipitate the sediment flowing into the rainwater pipe under different rainfall conditions, reduce the problems of rainwater bucket blockage and pipe blockage caused by sediment and garbage.

A gap 100 is formed between the protection assembly 4 and the upper part of the base 1. The filter cover 2 is movably arranged in the inner ring hole of the protection assembly 4. A plurality of water guide holes are formed on the protection assembly 4. The water guide holes are arranged along the radial direction of the protection assembly. The two ends of the water guide holes of the protection assembly respectively penetrate the outer ring surface and the inner ring surface of the protection assembly 4.

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

[0034] As a preferred embodiment, the bottom hole wall of the water guide hole is in the shape of an arc.

[0035] Referring to Figure 4 As shown in the figure, the protection assembly 4 includes an upper ring plate 41 and a lower ring plate 42 arranged coaxially.

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

[0037] The lower ring plate 42 is arranged 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 part of the lower ring plate 42 to the inner edge and the 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 in the shape of an arc.

[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 and the upper ring plate 41 and the lower ring plate 42 form a water guide hole. The filter cover 2 is movably arranged in the inner ring hole of the upper ring plate 41 and the lower ring plate 42.
