Detailed Description

In order to further understand and appreciate the structural features and advantages of the present invention, preferred embodiments and the accompanying drawings are described in detail as follows:

as shown in fig. 4, the gully device for solving the non-point source pollution of the rainwater comprises a coarse filter layer 1, a fine filter layer 2, a grating well cover 3, a well body 4 and a filter bag 5.

As the improvement of the utility model, the coarse filtration layer 1 has square hole and the overflow mouth baffle 12 of permeating water by PP material integrated into one piece bottom surface, and the inflow is hour, and the baffle can block that the rainwater directly flows into lower floor's overflow mouth, and there is carry handle hole 11 both sides for the carry of coarse filtration layer 1 draws the transport.

The fine filter layer 2 is made of PP materials, the bottom surface of the fine filter layer is provided with a circular water permeable hole and an overflow port 22, the two sides of the fine filter layer are provided with lifting holes 21, and the bottom of the overflow port is provided with an insect prevention switch 23.

The filter bag 5 is composed of a filter bag and a filter material, the filter bag is made of permeable coarse cloth, the sealing is controlled by a zipper, the shape of the filter bag is consistent with that of the bottom surface of the fine filter layer, and the filter material is formed by mixing gravel and activated carbon.

When the gutter inlet device is installed, a garden type or municipal type gutter inlet is selected according to the installation position. According to the engineering construction drawing, the positions of holes are selected at the reserved joints 43 of the pipelines on the four sides of the bottom of the well body 4, then the fine filter layer 2 is placed on the supporting bulges 42 inside the well body 4, the filter bag 5 is placed in the fine filter layer 2 after the fine filter layer is placed flat, then the coarse filter layer 1 is horizontally placed at the top of the fine filter layer 2, and finally the grid well cover 3 is installed on the cast iron edge 41 on the top of the well body 4, so that the installation of the whole rainwater inlet device is completed.
