The filter assembly 400 includes a support plate 410 disposed in the inner cavity of the well body 100 and a first filter body 420 and a second filter body 430 detachably connected above the support plate 410, the first filter body 420 and the second filter body 430 are both provided with a filter tank 421 . The notch of the filter tank 421 faces the drainage hole 230 , and the filter tank 421 also has a mesh filter surface 424 communicating with the inside of the well body 100 . After the well body 100 is installed, the drain holes 230 are distributed on the road surface. When draining water, water enters the inside of the well body 100 from the drain holes 230, and the branches, leaves and plastic bags on the street are collected in the first filter body 420 and the second filter body. The filtered water is collected in the filter tank 421 in the body 430 , and then the filtered water is discharged from the mesh filter surface 424 to the drain pipe 110 . Collect the sundries carried by the rainwater discharge to prevent all kinds of garbage from entering the sewer and produce peculiar smell. The garbage can be collected and treated in a unified way, and the rainwater can be preliminarily filtered to reduce pollution.

The bottom surface of the well main body 100 is provided with a drain port communicating with the drain pipe 110, and a plurality of horizontal bars (not shown) arranged at equal intervals are arranged along the length direction of the drain port. There are multiple layers of soft filter pads 500 on the rod. The soft filter mat 500 is made of activated carbon material or PP cotton, which can absorb the sediment and impurities in the water, forming another filter design after the garbage is filtered by the filter tank 421, improving the rainwater recovery rate and reducing urban sewage treatment. pressure.

The well cover assembly 200 includes a first cover 210 and a second cover 220 that are movably connected to the well body 100 through a rotating shaft, and a plurality of Circular drain holes 230, a plurality of drain holes 230 are arranged at equal intervals. In the past, most of the drainage holes 230 provided on the drainage manhole cover are long holes. However, for such drainage holes, because the area of garbage or leaves is larger than that of the drainage holes, it is easy to cause the accumulation of sundries at the drainage holes when the rainfall is large. If it cannot be drained in time, it may cause adverse effects such as waterlogging. However, the advantage that the drain hole 230 is preferably designed as a circle is that the leaves or garbage can be driven by the vortex of the water flow, and enter the inside of the well main body 100 more easily from the drain hole 230, so that foreign matter is no longer easily accumulated on the surface of the drain hole 230. , to solve the problem that the manhole cover is easily blocked by sundries and waterlogging occurs. The drainage hole 230 can not only be designed as a circle, but also can be designed as any desired shape such as a square or a rhombus according to actual conditions.

After the inner wall is closely fitted, the possibility of the internally filtered sundries flowing to the soft filter pad 500 from the side seam can be reduced.

The support plate 410 is arranged along the length direction of the well body 100, the two inner side walls of the well body 100 in the width direction of the inner cavity are fixed with vertical rods, and the support plate 410 is arranged between the two vertical rods. The first filter body 420 and the second filter body 430 are engaged with the support plate 410 to form a support structure on the bottom surface of the filter tank 421 .

The filter tank 421 is a structure whose cross-sectional area gradually decreases from the notch end to the other opposite end, and the mesh filter surface 424 is an inclined surface. Such a design has the effect of guiding the water flow, so that the water flow can flow to the drain pipe 110 more quickly. And the structure of the first filter body 420 and the second filter body 430 is equivalent to the state that the mesh filter surface 424 is from the notch to the other opposite end and the distance from the inner cavity of the well main body 100 is larger and larger, so that even foreign matter Or the garbage is collected in the filter tank 421, but the mesh filter surface 424 for drainage is not close to the well body 100, and there is still enough space for drainage, which is beneficial to the flow of water.

As shown in FIG. 3 , at least two horizontal supports 422 arranged at intervals are fixedly connected between the mesh filtering surface 424 and the opposite end surface, and the horizontal supports 422 are arranged close to the opening of the filter tank 421 . The cross support 422 has two functions. On the one hand, it is distributed at the notch of the filter tank 421 and can be used to strengthen its own strength when collecting sundries. On the other hand, after a large amount of rubbish or sundries are collected in the filter tank 421, when it is necessary to remove the first filter body 420 or the second filter body 430, it is easier to disassemble the cross support 422 by hand, and it is more convenient to remove the sundries. Items are lifted for processing.

The mesh filtering surface 424 is also fixed with at least three vertical struts 423 arranged at equal intervals and located below the horizontal support 422 . The vertical struts 423 are helpful to prevent large-area debris from completely covering and blocking the mesh filter surface 424, so that the water filtration can continue and reduce the impact on the drainage work of the mesh filter surface 424.

In this drainage well, first, two symmetrically arranged first filter bodies 420 and second filter bodies 430 are arranged in the well main body 100, and the filter tank 421 provided by the two filter bodies is used to collect sundries or garbage in rainwater , after filtering sundries, the water is discharged to the drainpipe 110 through the mesh filter surface 424, and the garbage can be recycled in a unified manner to prevent branches, leaves and plastic bags from entering the sewer and causing peculiar smell. Second, the drain hole 230 is preferentially designed to be circular. When a large amount of water is drained, it can enhance the ability to take away the garbage and discharge it into the main body 100 of the well, so as to avoid the accumulation of garbage or debris on the surface of the drain hole 230 and cause blockage, thus causing the disadvantage of urban waterlogging. influences.
