Description

Sewage intercepting rainwater outlet for sponge city

technical field

The utility model relates to an urban facility, in particular to a sponge city facility, in particular to a sewage intercepting rainwater outlet for the sponge city.

Background technique

As we all know, sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and dealing with natural disasters caused by rainwater, and can also be called "water elastic city". . The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed.

Sponge city is based on the theory and technology of comprehensive utilization of rainwater. It aims to restore the urban ecological water cycle system through artificial means, in order to solve the problem of abnormal drought and flood caused by the shortage of urban water resources. It can also achieve the effect of beautifying the city and improving the living environment of citizens. In a sponge city, rainwater can replenish groundwater, cities, lakes, etc. through permeable ground infiltration and green space stagnation. In addition, a large amount of rainwater is recovered through rainwater harvesting devices, waste flow devices, filtration devices, transmission channels and storage devices. Wherein the most critical thing is how to filter rainwater and send it into urban pipelines for utilization. For this reason, people have designed various sewage interception outlets. Such as Chinese patent 202122831431.0, an automatic opening and closing sewage intercepting rainwater outlet, which includes a sewage intercepting basket, sewage intercepting rainwater plate and opening and closing device, and a boom is connected between the sewage intercepting rainwater plate and the sewage intercepting basket to intercept sewage rainwater An opening and closing device is provided under the plate to control the opening and closing of the sewage intercepting rainwater plate. A pressure sensor and a controller are installed on the sewage intercepting rainwater plate, and the controller is wirelessly connected to the opening and closing device; The problem of clogging the rainwater outlet caused by accumulation can also prevent garbage from entering the urban drainage system, but this type of rainwater outlet has a complex structure, high manufacturing cost, and is easily damaged, so it must be improved.

Utility model content

The purpose of the utility model is to design a sewage intercepting stormwater outlet for the sponge city with a simple structure and low cost in view of a series of problems such as complex structure, high cost and easy damage of the existing sponge city stormwater outlet.

The technical scheme of the utility model is:

A sewage intercepting rainwater outlet for a sponge city, characterized in that it consists of a winged opening box 1 and a hanging basket 2, the front and rear sides of the box 1 are provided with longitudinal grid holes 3 for water outlet, A filter brick wall 4 is installed at the position opposite to the longitudinal grid hole 3; the surrounding and bottom of the hanging basket 2 are provided with a filtering structure 5 that can not only allow water to pass through but also retain large impurities in the water. 2. The water falling into the box body 1 is filtered by the filter brick wall and then discharged into the rainwater collection pipe from the longitudinal grid hole 3.

The filter structure 5 is densely arranged strip grid holes or densely distributed holes.

The hanging basket 2 is a truncated square cone with a large top and a small bottom.

On the front and rear sides of the box body 1, on the upper part of the longitudinal grid hole 3, there are weight reducing holes 6.

Both sides of the hanging basket 2 are provided with openings 7 for easy lifting.

A spoiler 8 is erected on the filter brick wall 4 .

The beneficial effects of the utility model:

The utility model has the advantages of simple structure, low manufacturing cost and uneasy damage. The shape is beautiful and generous.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1-4.

A sewage intercepting rainwater outlet for a sponge city, which is composed of a winged opening box 1 and a hanging basket 2, the hanging basket 2 is placed in the box 1, and there is a hanging basket shelf board for positioning the hanging basket 2 in the box 9. The size of the box body 1 is usually 500×300×300 (length, width and height, unit: mm), made of stainless steel, and the hanging basket 2 is also made of stainless steel, with a depth between 120-140 mm. The shape is a square cone structure with a large top and a small bottom. The front and rear sides of the box body 1 are all provided with longitudinal grid holes 3 for water outlet, as shown in Fig. 1 , and a weight-reducing hole 6 can also be set on the top of the longitudinal grid holes 3 if necessary. A filter brick wall 4 for filtering rainwater is installed at the position opposite to the longitudinal grid hole 3 inside the box body 1. The filter brick wall 4 can be made of permeable concrete mixed materials, and a spoiler 8 is erected on the filter brick wall 4. , as shown in Figure 2, the spoiler 8 adopts a porous plate (aperture 5mm, as shown in Figure 4) for the purpose of buffering the rainwater after it enters, and preventing excessive rainwater from bringing up the existing bottom sediment to cause secondary pollution. The four sides and the bottom of the hanging basket 2 are provided with a filter structure 5 that can not only allow water to pass through but also retain large impurities in the water (such as leaves, weeds, etc.), as shown in Figures 1 and 2, the filter structure 5 is a densely arranged elongated grid hole or densely distributed holes (circular, triangular or square), the figure is an elongated grid hole; the two sides of the hanging basket 2 are provided with openings 7 for easy lifting, as shown in picture 2.

During specific use, the upper part of the hanging basket 2 should also have a cover plate with holes. The rainwater passes through the cover plate from the road and then enters the hanging basket 2. The larger impurities in the rainwater are blocked by the hanging basket and then fall into the hanging basket. In the box body 1, the water in the box body 1 is discharged into the rainwater collection pipe from the vertical grid hole 3 after being filtered by the filter brick wall. When it is not raining, the hanging basket can be taken out regularly to remove impurities such as leaves therein.

The technical index of the utility model is:

1) Drainage capacity ≥ 25L/s.

2) Porosity>80%.

3) SS removal rate ≥ 90%.

4) Ammonia nitrogen removal rate ≥ 95%.

5) Total nitrogen removal rate ≥ 95%, total phosphorus removal rate ≥ 85%.

6) COD removal rate ≥ 80%.

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
