[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 The utility model provides a technical solution: a sponge city surface water filtration module based on active diversion, including an outer shell 1, an inlet pipe 2, an outlet pipe 3, a filter layer 4, a connecting pipe 5, a diversion main pipe 6, a No. 1 diversion branch pipe 7, a diversion side pipe 8, a No. 2 diversion branch pipe 9, a grille 10, a receiving plate 11, a clamping ring 12, a clamping block 13, and a spring 14.

[0029] The outer shell 1 is a hollow structure. An inlet pipe 2 is provided through the upper surface of the outer shell 1, and an outlet pipe 3 is provided through the lower surface of the outer shell 1. A filter layer 4 is provided inside the outer shell 1, and the filter layer 4 is located between the inlet pipe 2 and the outlet pipe 3. A grille 10 is mounted on the upper surface of the outer shell 1, and the surface of the grille 10 is connected to the outer shell 1 by bolts. A receiving tray 11 is fixedly installed on the inner wall of the outer shell 1. The receiving tray 11 is located below the filter layer 4, and the receiving tray 11 has an open upper surface. The lower surface of the receiving tray 11 is connected to the upper surface of the outlet pipe 3;

[0030] like Figure 1 and Figure 3 As shown, the shell 1 is embedded in the ground drainage system so that the upper surface of the shell 1 is flush with the ground. When the ground runoff enters through the water inlet pipe 2 on the surface of the shell 1, the grille 10 on the upper surface of the shell 1 preliminarily intercepts the debris in the water flow. The water flows into the interior of the shell 1 through the water inlet pipe 2, and is filtered by the filter layer 4. The filtered water falls to the upper surface of the receiving tray 11 and enters the collection system along the outlet pipe 3 for storage. The grille 10 on the upper surface of the shell 1 can be disassembled using bolts to facilitate cleaning of the grille 10.

[0031] A primary diversion structure is provided inside the housing 1. The primary diversion structure diverts the surface runoff to avoid a large amount of water impact on a certain area of ​​the filter layer 4. The primary diversion structure includes a connecting pipe 5, which is connected to the lower surface of the water inlet pipe 2. A diversion main pipe 6 is provided on the lower surface of the connecting pipe 5. A first diversion branch pipe 7 is provided on the outer surface of the diversion main pipe 6. A plurality of first diversion branch pipes 7 are arranged in a ring on the lower surface of the connecting pipe 5 with the diversion main pipe 6 as the center of the circle. The ends of the diversion main pipe 6 and the first diversion branch pipe 7 are respectively located above the filter layer 4. A secondary diversion structure is provided on the surface of the connecting pipe 5. The secondary diversion structure avoids the diversion main pipe 6 from being unable to carry excessive water flow by further diverting the runoff.

[0032] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, when water flows into the device through the water inlet pipe 2, the water flows along the water inlet pipe 2 into the connecting pipe 5. The water in the connecting pipe 5 is diverted by the diversion main pipe 6 and the No. 1 diversion branch pipe 7. The surface water entering the device passes through the diversion main pipe 6 and the end of the No. 1 diversion branch pipe 7 and falls evenly on the upper surface of the filter layer 4, avoiding a large amount of runoff water from concentrating in a certain area of ​​the filter layer 4, causing the filter medium of the filter layer 4 to be impacted by excessive water flow, thereby affecting the filtering effect.

[0033] The secondary diversion structure includes a diversion side pipe 8, which is arranged on the side surface of the connecting pipe 5. The outer surface of the diversion side pipe 8 is penetrated by a second diversion branch pipe 9, and multiple second diversion branch pipes 9 are arranged in an annular manner on the outer surface of the diversion side pipe 8. The diversion side pipe 8 and the second diversion branch pipe 9 are arranged in an annular manner on the outer surface of the connecting pipe 5. The ends of the multiple second diversion branch pipes 9 are located on the upper surface of the filter layer 4. The inner wall of the diversion side pipe 8 is provided with a flow blocking structure, which blocks the flow of water. The force of the clamping block 13 automatically opens the shunt side pipe 8. The flow blocking structure includes a clamping ring 12. The clamping ring 12 is annular and fixedly mounted on the inner wall of the shunt side pipe 8. The inner surface of the clamping ring 12 is engaged with the clamping block 13. The cross section of the clamping block 13 is a convex structure, and the clamping block 13 is slidably connected to the inner wall of the shunt side pipe 8 through a bracket. A spring 14 is fixedly mounted on one side of the clamping block 13, and the other end of the spring 14 is fixedly mounted on the inner wall of the shunt side pipe 8 through a hollow bracket.

[0034] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, when the water flow passing through the connecting pipe 5 in a short time is too large, the diversion main pipe 6 and the No. 1 diversion branch pipe 7 cannot bear the load. At this time, the water flows from the diversion side pipe 8 on the side surface of the connecting pipe 5, and the water pushes the block 13 to one side inside the diversion side pipe 8. The block 13 slides on the inner wall of the diversion side pipe 8. The sliding block 13 compresses the spring 14 while separating from the clamping ring 12, so that the water flow can flow through the gap between the clamping ring 12 and the block 13 through the diversion side pipe 8, and fall from the No. 2 diversion branch pipe 9 at the end of the diversion side pipe 8 to the surface of the filter layer 4 for filtration, thereby improving the device's carrying capacity for water flow.

[0035] Working principle: When using the sponge city surface water filtration module based on active diversion, the surface runoff passes through the surface of the shell 1. Under the interception of the grille 10, the debris in the water flow is intercepted, and the water flow continues to move through the water inlet pipe 2 into the connecting pipe 5. At the end of the connecting pipe 5, after being diverted by the diversion main pipe 6 and the No. 1 diversion branch pipe 7, the water falls on the surface of the filter layer 4 for filtration. When the amount of water in the connecting pipe 5 is too large, the water flows through the diversion side pipe 8 on the side surface of the connecting pipe 5 to the No. 2 diversion branch pipe 9, and enters the surface of the filter layer 4 for filtration, thereby increasing the carrying capacity of the shell 1 for surface runoff, and avoiding a large amount of runoff water from concentrating in a certain area of ​​the filter layer 4, so that the filter medium of the filter layer 4 is impacted by excessive water flow, thereby affecting the filtration effect. The filtered water enters the collection system through the outlet pipe 3 for storage and standby, thereby increasing the overall practicality.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
