Description

Technical Field

[0001] The utility model belongs to the field of rainwater infiltration collection, and particularly relates to a rainwater infiltration collection and filtering device for a sponge city. Background Art

[0002] The concept of sponge city aims to manage rainwater in a natural way to reduce urban waterlogging and water waste. Rainwater collection and filtration structures are one of the important devices to realize the "sponge" nature of the city.

[0003] Existing rainwater infiltration collection and filtration devices are mainly divided into two types: above-ground drainage systems and underground recovery and filtration systems. When using the existing underground rainwater infiltration and filtration structure, due to its large size, it is often difficult for workers to perform subsequent maintenance or replacement after it is buried and installed, resulting in high maintenance costs. In addition, the general rainwater infiltration and filtration structure lacks an external protective structure and is easily damaged by external foreign objects during the burial process or use, thereby affecting its service life.

[0004] Therefore, in order to address the problems of high maintenance cost and short service life of the above-mentioned existing buried rainwater infiltration and filtration devices after installation, a sponge city rainwater infiltration collection and filtration device has been developed. By adding an underground protective shell, a limiting bearing structure and a water inlet filtration structure to the existing rainwater infiltration and collection device, the service life of the buried rainwater infiltration and collection device can be improved, and its effect on filtering and collecting rainwater can be improved. In addition, its subsequent maintenance cost can be reduced. Utility Model Content

The four corner edges of the lower end of the underground box body 1 are fixedly connected with an extension frame 10, the upper end of the extension frame 10 is fixedly connected with a protrusion 9, the upper end of the underground box body 1 is fixedly connected with a mounting buckle 8 symmetrically distributed on the left and right, the upper end of the ground cover 2 is fixedly connected with a water inlet 12, and an activated carbon filter layer 13 is installed at the center of the inner wall of the water inlet 12. The upper and lower ends of the ground cover 2 are penetrated with left and right opposite holes. The buckle grooves 11 are distributed, and the upper end of the water inlet cover 3 is provided with a first trough body 15. The lower end of the first trough body 15 is penetrated by a filter grid 16 with equal intervals. The four corner edges of the lower end of the water outlet end 7 are provided with grooves 14. The underground box body 1 can protect the high-efficiency filtration structure composed of the water inlet end 5, the filter cartridge 6, and the water outlet end 7, and the installation buckles 8 and the protrusions 9 can be used to quickly disassemble and assemble the high-efficiency filtration structure composed of the water inlet end 5, the filter cartridge 6, and the water outlet end 7 and the ground cover 2, so that workers can replace or maintain the high-efficiency filtration structure buried underground.

[0027] See also Figure 3-Figure 5The filter element 6 is provided on the inner wall of the filter element 6, and the storage box 4 is provided on the inner wall of the lower end of the water outlet 7. When in use, the filtered and purified rainwater can be collected by the storage box 4, and the collected purified rainwater can be transported outwards in conjunction with the pipeline for subsequent use. The upper end of the extension frame 10 is fitted with the four corner edges of the lower end of the water outlet 7, and the protrusion 9 is adapted to the groove 14. When in use, the high-efficiency filtering structure composed of the water inlet 5, the filter element 6 and the water outlet 7 can be limited and carried by the extension frame 10, so that workers can take it out of the underground box 1 for maintenance.

[0028] See also Figure 3-Figure 7 In this embodiment, the ground cover 2 is installed at the upper end of the water inlet end 5, and the installation buckle 8 is adapted to the buckle groove 11. When in use, the rainwater entering the ground can be guided through the ground cover 2, and the small particles of impurities therein can be filtered in conjunction with the activated carbon filter layer 13. The water inlet cover 3 is installed on the water inlet 12, and the water inlet 12 is connected to the ground cover 2. When in use, the rainwater infiltrating from the surface can be preliminarily filtered through the water inlet cover 3 to filter out the impurities therein.

Then, backfill the soil and lay permeable bricks on the surface of the water inlet cover 3.

[0030] When in use, rainwater flows into the water inlet cover 3 through the seepage bricks, and the filter grid 16 performs preliminary filtration on the infiltrating rainwater, and the activated carbon filter layer 13 then filters and adsorbs the fine particles in it;

[0031] The rainwater that has been initially filtered and adsorbed flows into the water inlet 5 and then flows into the multiple filter cartridges 6 for secondary filtration and purification. The filtered and purified rainwater then flows into the storage tank 4 from the water outlet 7 for storage.

[0032] When rainwater is needed, the filtered rainwater in the storage tank 4 can be transported outward for use through pipes and water pumps.

[0033] Through the above steps, the high-efficiency filtering structure composed of the water inlet end 5, the filter cartridge 6, and the water outlet end 7 can be protected by the underground box 1, and the high-efficiency filtering structure composed of the water inlet end 5, the filter cartridge 6, and the water outlet end 7 and the ground cover 2 can be quickly disassembled and assembled in conjunction with the mounting buckle 8 and the protrusion 9, so that workers can replace or maintain the high-efficiency filtering structure buried underground, thereby solving the problems of high maintenance cost and short service life of the existing buried rainwater infiltration filtering device after installation.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
