Description

Gutter inlet cut-off device and gutter inlet drainage facility applying same

Technical Field

The utility model relates to a gutter inlet cut-off equipment still relates to this gutter inlet cut-off equipment's application.

Background

The rainwater drainage of urban roads is of great importance and is directly related to the treatment level of cities, and the rainwater inlet is a rainwater collection structure in an urban road rainwater drainage system and is an important way for ensuring that the urban roads quickly and effectively collect and discharge ground rainwater. Generally, the rainwater collection and purification device is arranged at a certain distance from a crossroad and a roadside and at a low-lying position provided with a flat kerbstone and a vertical kerbstone so as to prevent rainwater from overflowing a road or causing water accumulation on the road and the low-lying position to hinder traffic. Therefore, the current urban rainwater drainage system is not very suitable for the construction of sponge cities, particularly, in the sponge city construction process, the collection of the road surface rainwater in the built section area is difficult, the road surface rainwater directly enters a municipal rainwater pipe network through a rainwater port, and the road surface pollutants are directly drained into a river channel through the municipal rainwater pipe network to indirectly pollute the water quality of the river channel, so that the purification of the road surface rainwater is particularly important, and the application of the rainwater port sewage intercepting hanging basket intercepting facility is particularly important.

In order to solve the problem, the existing gutter inlet structure is like a Chinese utility model patent with the patent number ZL202121572788.5 (the publication number is CN 215563194U) which discloses a gutter outlet with initial rainwater purification function, the lower end of the gutter outlet is connected with a transverse drainage pipeline, the circumference of the gutter outlet is provided with a circle of initial rainwater interception processing area, the initial rainwater interception processing area is internally provided with a filtering material and is arranged with the soil all around for water permeability. This inlet for stom water structure makes the rainwater from flowing into rain comb back all around, holds back earlier and gets into the interval region then soaks down again and filters, avoids initial stage rainwater to soak direct inflow outlet not in time, guarantees the filtration treatment effect to initial stage rainwater, but when the rainfall was too big, still has the rainwater directly to discharge to horizontal drainage pipe from the outlet of vertical setting directly, and does not pass through the restriction of intercepting dirty, need do further improvement for this reason.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the first technical problem that provides a can improve rainwater and cut dirty treatment effect and easily the gutter inlet cut-off equipment of pipe is supported in later stage to above-mentioned prior art current situation.

The utility model aims to solve the second technical problem that provide an use inlet for stom water drainage facility that has above-mentioned inlet for stom water cut-off equipment to above-mentioned prior art current situation.

The utility model provides a technical scheme that first technical problem adopted does: this gutter inlet cut-off equipment includes the open basket body of hanging in top, its characterized in that: the hanging basket is characterized in that an overflow chamber which is relatively isolated and communicated with a municipal rainwater pipe is arranged in the hanging basket body, overflow holes which are in fluid communication with the hanging basket body are formed in at least one side wall of the overflow chamber, a sewage interception part is arranged on the top wall of the overflow chamber, a water outlet part communicated with sponge facilities outside a sidewalk is formed in the bottom of the hanging basket body, and the water outlet part is lower than the overflow holes, so that an accumulation space for accumulating sewage is formed between the part of the overflow chamber below the overflow holes and the peripheral wall of the hanging basket body.

In order to realize that the rainwater can be further filtered after the initial stage of the rainwater passing through the sewage intercepting part of the overflow chamber is filtered, preferably, the upstream of the hanging basket body corresponding to the water outlet part is provided with a sewage intercepting device. This cut dirty device can select to have the dirty board of cutting of different aperture sizes among the prior art to can distinguish with the aperture size of cutting dirty portion, the aperture is less than the aperture of cutting dirty portion promptly, forms thick, thin two-stage and holds back, cuts dirty effect better.

From the perspective of simple structure, preferably, the dirt blocking device is a dirt blocking hole directly formed on the side wall of the hanging basket body corresponding to the water outlet portion.

Also in order to achieve interception of the dirt entering the overflow chamber, it is preferred that the dirt interception of the top wall of the overflow chamber consists of a set of parallel bars. The aperture formed between the parallel grid bars is larger, the rainwater drainage capability can be better, and the garbage interception can be realized.

The utility model provides a technical scheme that second technical problem adopted does: the gutter inlet drainage facility comprises a water collecting well communicated with a municipal rainwater pipe and a flat grate and/or a vertical grate which are arranged at the wellhead of the water collecting well and used for drainage, wherein the hanging basket body is placed at the wellhead of the water collecting well, the flat grate and/or the vertical grate are arranged at the upper opening of the hanging basket body, a water outlet channel communicated with the water outlet is communicated with a sponge facility outside a sidewalk of a sponge city, and an overflow chamber is communicated with the water collecting well.

In order to enable the hanging basket body to be firmly placed on a water collecting well mouth of the rainwater port, preferably, a mounting plate capable of being placed on the water collecting well extends along the horizontal direction on the periphery of the top of the hanging basket body.

Compared with the prior art, the utility model has the advantages of: due to the sewage interception part arranged on the top wall of the overflow chamber, when rainwater enters the hanging basket body, sewage is firstly intercepted, so that an initial filtering effect is achieved, when rainfall is small, rainwater cannot flow into the overflow hole, rainwater on the road surface flowing into the rainwater inlet through surface runoff can be precipitated, intercepted and drained to the sponge facility on the outer side of the sidewalk on the outer side of the road to be purified and accumulated, and therefore the problem of initial rainwater source pollution is solved, when the rainfall is large, rainwater stored in the sponge facility on the outer side of the sidewalk can flow through the overflow hole, enters the overflow chamber from the overflow hole and flows into the municipal rainwater pipe network, the water passing section and the drainage capacity of the original municipal rainwater are guaranteed, so that water safety is guaranteed, in addition, due to the sewage interception part arranged on the top wall of the overflow chamber, rainwater entering the municipal rainwater pipe can be always filtered initially, so that the rainwater purification procedure in the municipal rainwater pipe network is relieved, blockage is avoided, and smooth drainage work can be fully guaranteed; finally, the dirt accumulated in the accumulation space, such as settled sand, leaves and other large garbage, can be regularly cleaned.
