Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to a sponge city landscape-style rainwater collection and purification device. Background Technology

[0002] Sponge city, a new generation of urban stormwater management concept, refers to a city's ability to adapt to environmental changes and cope with natural disasters caused by rainwater, much like a sponge. It can also be called a "water-resilient city." A sponge city includes not only water systems such as rivers, lakes, and ponds, but also urban infrastructure such as green spaces, gardens, and permeable pavements. Rainwater is absorbed, stored, purified, and reused through these "sponges," with the remaining runoff discharged through pipe networks and pumping stations. This effectively improves the standards of the urban drainage system and alleviates the pressure of urban flooding. The new "sponge" is required to integrate with the urban landscape and possess functionality to create a relaxing, comfortable, and ecological living environment. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a sponge city landscape-style rainwater harvesting and purification device, specifically employing the following technical solution:

[0004] The sponge city landscape rainwater harvesting and purification device of this utility model includes a rest pavilion and a landscape ecological pool located at its center. The landscape ecological pool includes glass sidewalls, and glass covers are spaced apart on the top of the glass sidewalls. The inner cavity of the landscape ecological pool is divided into an upper purification zone and a lower ecological zone. The purification zone is provided with a support perforated plate, a filter cotton layer, a volcanic rock layer, and a ceramic ring layer from bottom to top. The bottom of the ecological zone is provided with a layer of expanded clay sand for planting aquatic plants. The ecological zone is provided with a bottom drainage pipe connected to the municipal rainwater pipe network and an internal circulation pipe extending upward to the purification zone. The inner circulation riser is equipped with a circulation pump, and an overflow pipe connected to the bottom drain pipe is installed at the top of the purification area.

Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 yes Figure 1 Main view (filler and aquatic plants in the purification and ecological zones are omitted). Detailed Implementation

[0014] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0015] The sponge city landscape rainwater collection and purification device of this utility model includes a rest pavilion and a landscape ecological pond set in the center of it.

[0016] like Figure 1 , 2 As shown, the landscape ecological pond includes glass sidewalls 1, with glass roofs 2 spaced apart on top of the glass sidewalls 1. Specifically, the glass sidewalls 1 and the glass roofs 2 are connected by struts. The glass sidewalls 1 are made of ultra-clear tempered glass with a thickness of 5-10mm, and the glass roofs 2 are made of tempered glass with a thickness of 5mm. In this embodiment, the landscape ecological pond is a square pond, and the glass sidewalls 1 are formed by sealing and splicing four pieces of ultra-clear tempered glass. Furthermore, reinforcing ribs are installed between adjacent ultra-clear tempered glass pieces.

[0017] The volume of the landscape ecological pond is determined based on the local rainfall and the amount of rainwater collected by the facilities. Its interior is divided into an upper purification zone and a lower ecological zone. The purification zone, from bottom to top, consists of a support perforated plate 31, a filter cotton layer 32, a volcanic rock layer 33, and a ceramic ring layer 34. The bottom of the ecological zone contains a layer of expanded clay aggregate 42 for planting aquatic plants 41. The volume ratio of the purification zone to the ecological zone is 1:5. Under normal circumstances (the purification zone is 0.5m high), the support perforated plate 31 is a 2mm thick hot-dip galvanized perforated plate with a 3mm pore diameter; the filter cotton layer 32 is composed of 10cm thick polyurethane sponge; the volcanic rock layer 33 is composed of 20cm thick volcanic rock with large pores, 10cm particle size, and 3mm pore diameter; the ceramic ring layer 34 is composed of ceramic rings with a diameter of 3cm laid at a thickness of 20cm; the expanded clay sand layer 42 is composed of expanded clay sand with a particle size of 2cm laid at a minimum thickness of 30cm; and the aquatic plants 41 include one or more of centipede grass, Antarctic pine, Vallisneria natans, and goldfish algae. Ornamental fish can also be raised in the ecological zone.

[0018] To ensure water quality and oxygen requirements for fish in the landscape ecological pond, an internal circulation lift pipe 51 extending upwards from the ecological zone to the purification zone is installed. A circulation pump 52 is installed on the internal circulation lift pipe 51. Activating the circulation pump 52 continuously lifts water from the ecological zone to the purification zone, where it is purified through various filtration layers before returning to the ecological zone. Maintaining adequate water quality not only promotes the survival and growth of the landscape organisms but also keeps the glass sidewalls 1 clean, thus ensuring a better viewing experience. Furthermore, a bottom drain pipe 53 connected to the municipal stormwater network (or urban green space) is installed at the bottom of the ecological zone, and an overflow pipe 54 connected to the bottom drain pipe 53 is installed at the top of the purification zone. When the water volume in the landscape ecological pond is excessive, it can be discharged into the municipal stormwater network (or urban green space) through the overflow pipe 54 and the bottom drain pipe 53. In this embodiment, two sets of the internal circulation lift pipe 51, circulation pump 53, overflow pipe 54, and bottom drain pipe 53 are installed, arranged diagonally along the landscape ecological pond. Normally, a control valve 55 is installed on the bottom drain pipe 53.

[0019] The rest pavilion comprises a base slab 61, columns 62, and a canopy 63 surrounding the landscaped ecological pond. The base slab 61 is a regular quadrilateral structure raised above ground level (the bottom drainage pipe 53 is typically buried below the base slab 61). The columns 62 are located at the four corners of the base slab 61, and walking steps 64 are provided along the four sides of the base slab 61. Benches 65, connected to the columns 62, are located on both sides of the walking steps 64. The benches 65 are 45cm high and constructed from 10cm thick anti-corrosion wood. The columns 62 are made of 3mm thick Q235B galvanized square steel, with a centrally mounted lighting fixture 66. The lighting fixture 66 uses a 30W LED light and is equipped with sensors and timers to automatically switch on and off based on visitor numbers and time.

[0020] A modular solar panel 67 is installed on the pavilion cover 63. The solar panel 67 has an inward slope between the column 62 and the glass sidewall 1, and the rain-falling end of the solar panel 67 is connected to the glass sidewall 1, so that rainwater falling on the solar panel 67 can be collected in the landscape ecological pond as much as possible. A battery, controller and inverter connected to the solar panel 67 are also installed on the lower surface of the pavilion cover 63. The battery is used to power the circulation pump 52 and the lighting 66.
