Furthermore, the upper part of the overflow filter head is a straight pipe section, the peripheral side walls of the overflow filter head are provided with longitudinal rectangular water filtering holes, the width of each hole is 3-5mm, the top of each hole is sealed by a cover plate, the lower part of each hole is a reducer section and is connected with the overflow vertical pipe, and the diameter of the straight pipe section of the filter head is 1.5 times that of the overflow vertical pipe.
Furthermore, the connection mode between the overflow filter head and the overflow vertical pipe adopts threads, hot melting or socket joint.
Further, a drain pipe at the bottom of the gully is connected to the storm water manhole.
The bottom rainwater sedimentation zone can be used for settling and collecting particles and suspended matters in rainwater. The sedimentation zone can be modified according to the requirements, and the sedimentation effect can be increased if the sedimentation zone is set to be V-shaped.
In the invention, rainwater is subjected to primary filtration by the rainwater grate and secondary filtration by the grid basket dirt-intercepting groove and then is subjected to tertiary filtration in the rainwater settling area, sand and stone particles are settled in the rainwater settling area and then pass through the overflow filtration area, and clear water is collected by the overflow filtration head, passes through the overflow vertical pipe and then is discharged to the rainwater inspection well through the discharge pipeline. The environment-friendly gutter inlet with three-stage filtration has the following advantages: the rainwater inlet overflow filtering device has the advantages of being simple in structural design, easy to manufacture and maintain, low in cost, easy to popularize and apply and the like.

Detailed Description
In order to make the objects, technical solutions and technical features of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments, and it should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
As shown in fig. 1, the three-stage filtration environmental-friendly gutter inlet of the embodiment of the present invention is a three-dimensional schematic view, and the environmental-friendly gutter inlet can be applied to the municipal drainage field to realize the functions of rainwater collection, drainage and purification, and the three-stage filtration environmental-friendly gutter inlet of the embodiment comprises a sand rainwater grate 1, a grid basket dirt intercepting groove 2, a rainwater settling zone 3, an overflow filtration zone 4, and a discharge pipeline 5, and is characterized in that: the rainwater grate 1 is a primary filtering system and is positioned at the inlet of the top of the rainwater port and is flush with the road surface; the grid basket sewage intercepting groove 2 is used for secondary filtration and is positioned right below the rainwater grate, the size of the upper part of the grid basket sewage intercepting groove is the same as that of the rainwater grate, the length and width of the lower part of the grid basket sewage intercepting groove are 0.5-0.8 times of the length and width of the upper part of the grid basket sewage intercepting groove, longitudinal strip-shaped water filtering holes are arranged on the bottom and the peripheral side walls of the grid basket sewage intercepting groove, the width of each hole is 5-10mm, and the direction of each hole is perpendicular; the rainwater sedimentation zone 3 is the bottom area of the rainwater port, and sand and stone particles are sedimentated at the bottom area; the overflow filtering area 4 is a three-stage filtering area, and is composed of an overflow filtering head 41 and an overflow vertical pipe 42, and is positioned at the center of the bottom, the bottom of the overflow filtering area 4 is provided with an embedded waterproof casing 43, the overflow vertical pipe 42 penetrates through the bottom of the gully through the embedded waterproof casing 43, and a sealing material can be arranged between the overflow vertical pipe 42 and the embedded waterproof casing 43; the drainage pipe 5 is a gutter inlet connecting pipe 52 connected with a rainwater inspection well and is connected with the overflow vertical pipe 42 through an elbow 51.
