Description

Sewage intercepting device and drainage pipeline system

Technical Field

The utility model relates to the field of municipal pipelines, in particular to a sewage interception device and a drainage pipeline system.

Background

Municipal pipelines are important components of municipal public facilities, are used for urban drainage, and undertake important roles in beautifying the appearance and appearance of a city and guaranteeing the trip of citizens. In rainy seasons, waterlogging often occurs in many cities, and one of the main reasons for waterlogging is that the design of drainage pipelines is not reasonable enough and the drainage capacity is not enough.

Municipal drainage systems typically include sewer pipes and storm water pipes, where the storm water pipes are used to collect storm water and deliver it to rivers. Rainwater pipeline all sets up a plurality of outlet, and the outlet distributes in each corner in city, and during rainy, the rainwater gets into rainwater pipeline through the outlet.

From the analysis of the waterlogging of various cities, the blockage of the water outlet is one of the important causes of the waterlogging. The outlet sets up the filter screen usually for the interception various impurity, nevertheless because the filtration pore size of filter screen is less, piles up behind the filter screen when great impurity such as leaf, can cause the filter screen to block up, influences the rainwater throughput in outlet, causes ponding. However, if the filtering holes are enlarged or the filtering net is directly cancelled, rainwater impurities are increased to influence the water quality, and even the rainwater pipeline is blocked in a large area and cannot be compensated.

Disclosure of Invention

The utility model aims to provide a sewage interception device and a drainage pipeline system, which adopt a layered filtration mode to reduce the risk of blockage of a drainage outlet and improve the drainage capacity.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a sewage interception device comprises a hanging basket and a filter screen, wherein the hanging basket and the filter screen are arranged in a split manner; the hanging basket comprises a bottom plate and at least three side plates, and the lower ends of the side plates are fixedly connected with the bottom plate; the side plates are sequentially connected end to end in an annular mode, the bottom plates jointly enclose a sewage intercepting space, and an opening is formed in the upper end of the sewage intercepting space; the bottom plate and the side plate are respectively provided with a lower filtering hole, the filter screen is provided with an upper filtering hole, and the upper filtering hole is larger than the lower filtering hole.

The hanging basket and the filter screen are arranged in a split mode, when the hanging basket is used, the hanging basket is arranged below the filter screen, rainwater enters the hanging basket after being filtered by the filter screen, and the rainwater is filtered for the second time by the hanging basket. Because the upper filtering holes are larger than the lower filtering holes, the filter screen and the hanging basket can filter impurities with different sizes or types in a step-by-step filtering mode, the risk of blockage of a water outlet is reduced, and the water drainage capacity is improved.

Preferably, at least one side plate is provided with a lifting unit for taking out the hanging basket from the water outlet, so that the hanging basket can be conveniently mounted and filtered impurities can be poured.

Preferably, the upper end of the side plate is provided with a flange extending outwards, and after the side plate is installed, the flange is in contact with the water outlet and is used for supporting the whole hanging basket.

Preferably, the cross-sectional area of the sewage intercepting space is gradually increased from bottom to top.

Preferably, the upper filtering hole and the lower filtering hole are both in a long strip shape, and the length and/or the width of the upper filtering hole are larger than those of the lower filtering hole.

Preferably, the extension direction of the lower filtering holes and the extension direction of the upper filtering holes are inclined or perpendicular to each other, so that the impurity intercepting and filtering capability is improved.

Preferably, the bottom plate is obliquely arranged, impurities intercepted by the hanging basket are accumulated to the lower side of the bottom plate along the oblique direction of the bottom plate, and the integral drainage capacity of the hanging basket is guaranteed.

The utility model provides a drainage pipe system, includes pipeline and outlet, the outlet be equipped with as above cut dirty device, wherein hang the basket setting at the filter screen inboard.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Examples

As shown in figure 1, the drainage pipeline system comprises a pipeline and a drainage outlet 1, wherein the drainage outlet 1 is provided with a sewage interception device, the sewage interception device comprises a hanging basket 2 and a filter screen 3, the hanging basket 2 and the filter screen 3 are arranged in a split mode, and the hanging basket 2 is arranged on the inner side of the filter screen 3.

As shown in fig. 2-4, the hanging basket 2 comprises a bottom plate 24 and at least three side plates 25, wherein the lower ends of the side plates 25 are fixedly connected with the bottom plate 24. The side plates 25 are sequentially connected end to end in an annular mode, the bottom plates 24 jointly enclose a sewage intercepting space, and an opening is formed in the upper end of the sewage intercepting space.
