[0036] Please refer to Figures 1 to 6 A sponge city rainwater utilization device provided in an embodiment of the present application includes an interception box 1, a buffer box 2 and a filter box 3 which are connected in sequence through a circulation pipe 9; an interception net 4 is provided in the interception box 1, and the interception net 4 is located below the water inlet of the interception box 1, and is used to preliminarily intercept foreign matter entering the interception box 1 with rainwater; a plurality of partitions 21 are provided in the buffer box 2, and the partitions 21 are used to reduce the water flow velocity in the buffer box 2 so that the silt is gradually settled in the buffer box 2; a filter assembly is provided in the filter box 3 for filtering the settled rainwater, and the water outlet of the filter box 3 is connected to a reservoir (not shown in the figure).

[0037] Rainwater enters the interception box 1 through the drainage ditch. The water inlet of the interception box 1 is located above the interception net 4. After the rainwater enters, it can pass through the interception net 4 to intercept the leaves, plastic bags and large particles of mud and sand (i.e., large-sized foreign objects) it carries. Then the rainwater enters the buffer box 2. Under the action of multiple partitions 21, the water flow rate gradually decreases, and the carried fine mud and sand gradually settles in the buffer box 2. Then the rainwater enters the filter box 3. The water inlet of the filter box 3 is located above the filter assembly. After filtration, the rainwater can enter the reservoir from the water outlet of the filter box 3 for storage so that the rainwater can be used later.

[0038] According to some embodiments of the present application, the interception net 4 includes a mounting ring 41 adapted to the inner wall of the interception box 1, and a mesh bag 42 connected to the lower side of the mounting ring 41, and the inner wall of the interception box 1 is provided with a plurality of protrusions 11 for supporting the mounting ring 41. Specifically, the mounting ring 41 is a rectangular ring structure adapted to the inner wall of the interception box 1, and a plurality of protrusions 11 are evenly distributed on the four inner side walls of the interception box 1, and the lower side of the mounting ring 41 is supported on the plurality of protrusions 11. The water inlet of the interception box 1 is located above the mounting ring 41 to ensure that large-sized foreign objects carried by the incoming rainwater can be intercepted. The open end of the mesh bag 42 is connected to the lower side of the mounting ring 41, and the mesh bag 42 can be a wire mesh bag or a nylon mesh bag. The connection method of the mesh bag 42 and the mounting ring 41 can be: a plurality of hooks are evenly arranged on the lower side of the mounting ring 41, and a plurality of hanging rings are evenly arranged at the open end of the mesh bag 42, and the connection between the two can be achieved by hanging the hanging rings on the hooks.

[0039] According to some embodiments of the present application, a plurality of handles 411 are provided on the upper side of the mounting ring 41, and the handles 411 are used to lift the interception net 4 as a whole out of the interception box 1. Specifically, two handles 411 can be evenly distributed on the upper side of the mounting ring 41, so that the interception net 4 can be lifted by hand conveniently, thereby cleaning the foreign matter intercepted in the interception net 4.

[0040] According to some embodiments of the present application, a plurality of the baffles 21 are arranged at intervals along the water flow direction, and adjacent baffles 21 are alternately distributed on two opposite inner side walls of the buffer box 2 that are perpendicular to the water flow direction, and a gap is left between the baffles 21 and the opposite inner side walls. With such an arrangement, the flow path of the water flow in the buffer box is roughly S-shaped, which not only has a good deceleration effect and is conducive to sedimentation, but also the sediment will settle to the bottom of the box after colliding with the baffles and decelerating, so less sediment moves to the water outlet of the buffer box, thereby reducing the impurities entering the filter box.

[0041] According to some embodiments of the present application, the lower side of the partition 21 is connected to the bottom of the buffer box 2, and a gap is left between the upper side of the partition 21 and the top of the buffer box 2. The water inlet of the buffer box 2 is set at a position lower than the upper side of the partition 21, and the water outlet is set at a position higher than the upper side of the partition 21, which can further reduce the sediment at the water outlet.

[0042] According to some embodiments of the present application, the water inlet and the water outlet of the buffer box 2 are far away from the bottom of the buffer box 2. Since the sediment settles at the bottom of the buffer box, such a setting can reduce the disturbance of the sediment at the bottom of the box.

[0043] According to some embodiments of the present application, the filter assembly includes a support plate 5 and a filter plate 6. The support plate 5 divides the interior of the filter box 3 into two upper and lower chambers. The support plate 5 includes an inclined section 51 and a horizontal section 52 connected to the lower end of the inclined section 51, wherein the inclined section 51 is a mesh plate, and the horizontal section 52 is a non-mesh plate. The filter plate 6 covers the inclined section 51. The water inlet of the filter box 3 is connected to the chamber above the filter plate 6, and the water inlet is located at the high end of the inclined section 51. In this design, water flows into the filter plate after flowing into the water inlet. Since the inclined section is provided, the water will flow along the inclined filter plate, which can wash away the fine sediment on the filter plate, so that the sediment continuously moves toward the horizontal section, which is convenient for cleaning the sediment.

[0044] According to some embodiments of the present application, a collection box 7 is provided on the horizontal section 52, the top of the collection box 7 is lower than the lower edge of the filter plate 6, and a drain port 31 is provided on the side where the filter box 3 and the horizontal section 52 meet, and the drain port 31 is blocked by a plug 311. By providing a collection box, the silt moving to a lower position can be settled into the collection box, which is convenient for removal and cleaning. Specifically, before cleaning, the plug 311 can be opened first to drain the residual water in the upper chamber of the filter box 3, and then the collection box 7 can be taken out for cleaning.

[0045] According to some embodiments of the present application, the water outlet of the buffer box 2 is provided with a filter cover 22, and the filter cover 22 is provided on the inner wall of the buffer box 2 to pre-filter the water outlet of the buffer box 2. Specifically, the filter cover 22 includes a cover seat 221 and a cover body 222, and the cover seat 221 is fixedly installed on the inner wall of the buffer box 2 by bolts, and a positioning ring 2211 is provided on the cover seat 221. The cover body 222 is cylindrical, and the opening of the cover body 222 is snap-fitted to the positioning ring 2211, thereby realizing the snap-fitting of the two, and conveniently removing the cover body for cleaning or replacement.

[0046] According to some embodiments of the present application, a sewage cleaning pipeline 8 connected between the interception box 1 and the buffer box 2 is also included, and the sewage cleaning pipeline 8 is provided with a sewage pump 81 for cleaning sewage from the interception box 1 and the buffer box 2. The bottom of the interception box 1 is provided with an inclined bottom plate 12, and the water outlet of the interception box 1 is located at the high end of the bottom plate 12. In this way, larger silt particles will be deposited at the low end of the bottom plate 12. The interception box 1 is provided with a sewage outlet 13 (usually blocked), and the sewage outlet 13 is located at the low end of the bottom plate 12, which is also convenient for sewage cleaning. Since there is rainwater in the buffer box 2 before sewage cleaning, the sludge deposited at the bottom of the buffer box 2 is shoveled by a shovel to form a suspension with water. At the same time, the sludge deposited at the bottom of the interception box 1 is shoveled by a shovel, and then the sewage in the buffer box 2 is pumped into the interception box 1 by the sewage pump 81, and the sludge in the interception box 1 is washed with sewage and discharged from the sewage outlet 13. In this way, the sewage cleaning operation of the interception box 1 and the buffer box 2 can be realized.

[0047] It should be noted that the interception box 1, buffer box 2 and filter box 3 can be designed as a structure with a box cover that can be opened, so as to facilitate cleaning. The solid arrows in the figure indicate the flow direction of rainwater, as well as the positions of the water inlet and outlet of the interception box 1, buffer box 2 and filter box 3; the dotted arrows indicate the flow direction of sewage during cleaning. Some valves can be set on the circulation pipe 9 and the sewage cleaning pipeline 8 as needed, so that the flow path can be conveniently controlled according to operational needs, which will not be repeated here.
