Description

Technical Field

[0001] This utility model relates to the field of exterior wall greening technology, specifically to a non-powered modular rainwater self-cleaning planting box for building facade greening. Background Technology

[0002] Increasing the greening rate is one of the key ways to improve the urban ecological environment and beautify the urban landscape. However, with urban renewal projects mostly concentrated in core areas or old urban areas, the public space available for ground greening is severely limited due to high development intensity and large plot ratio, often requiring the use of "vertical greening" as an alternative. But the implementation of vertical greening currently faces many challenges: the supporting irrigation and power facilities are difficult to upgrade and prone to failure; there is a lack of a systematic rainwater collection and utilization system, making it difficult to achieve long-term low-cost maintenance; the installation and replacement of vertical greening components are inconvenient, some devices have complex structures and messy appearances, failing to effectively integrate with the building facade, and may even affect the original waterproofing and thermal insulation performance of the wall due to improper installation.

[0003] Currently, existing vertical greening technologies mainly focus on modular structure design and rapid installation. Although they have made some progress in improving construction efficiency, shortening construction period, and reducing on-site pollution, they generally fail to integrate rainwater collection, self-cleaning function, circulating irrigation system, and the decorative aspect of the facility itself into the modular unit, resulting in insufficient overall integrity and aesthetics.

[0004] In terms of rainwater harvesting and self-purification technology, although existing systems can store and reuse rainwater, the core problem lies in their heavy reliance on electricity. High energy consumption not only increases operating costs but also contradicts the goals of green and low-carbon development. Utility Model Content

[0005] The purpose of this utility model is to provide a non-powered modular rainwater self-cleaning planting box for greening building facades. It can efficiently and automatically collect and store rainwater for plant irrigation. At the same time, through its modular design, it achieves self-cleaning and high integration of rainwater storage, planting and decorative components, enabling rapid installation and simple maintenance. It fundamentally solves the problems of high energy consumption, difficult maintenance, easy damage, poor decorative effect and complicated installation that are common in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-powered modular rainwater self-cleaning planting box for greening building facades, including a roof and an exterior wall, wherein a building exterior wall decorative aluminum panel is fixedly installed on the exterior wall, and a fixing slot box is fixedly installed on the outer wall of the building exterior wall decorative aluminum panel, and a rainwater storage box is embedded in the top port of the fixing slot box.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a non-powered modular rainwater self-cleaning planting box for greening building facades includes a roof and an exterior wall. A building exterior wall decorative aluminum panel 15 is fixedly installed on the exterior wall, and a fixed slot box 5 is fixedly installed on the outer wall of the building exterior wall decorative aluminum panel 15. A rainwater storage box 6 is embedded in the top port of the fixed slot box 5. A planting box 7 is inserted into the port of the rainwater storage box 6, and the two are kept at a predetermined distance to form a sandwich. An S-shaped tube 51 is fixedly provided inside the fixed slot box 5. One end of the S-shaped tube 51 is fixedly connected to a vertical pipe 52 extending to the outside of the bottom of the fixed slot box 5. The side wall of the S-shaped tube 51 is fixedly connected to the interlayer.

[0022] Specifically, the planting box 7 is sequentially filled with a gravel cushion layer, a coarse sand layer, planting soil, and a surface covering layer. The surface covering layer can be expanded clay, gravel, or pebbles. Furthermore, the planting soil is coconut fiber soil or regular soil. The S-shaped tube 51 is fixedly connected to the interlayer at a location near the interface between the coarse sand layer and the gravel cushion layer in the gravel cushion layer.

[0023] Furthermore, the aforementioned fixed trough box 5 can be a polyethylene plastic box, a foam box, a wooden box, or an aluminum alloy box.

[0024] In the above technology, the residual water in the interlayer will maintain a predetermined liquid level. When it is higher than the interlayer connection of the S-shaped tube 51, the residual water in the interlayer will be discharged along the S-shaped tube 51, thereby ensuring that the liquid level in the interlayer is in a reasonable state to avoid root rot caused by prolonged soaking.

[0025] As a further embodiment of this utility model, combined with Figure 1 As shown, a rainwater inlet 1 is pre-installed on the roof, and the rainwater inlet 1 is fixedly connected to the other end of the S-shaped pipe 51. More specifically, the rainwater inlet 1 is connected to the S-shaped pipe 51 through a horizontally arranged straight discharge pipe 10. That is to say, the S-shaped pipe 51 here is responsible not only for the discharge of sewage from the interlayer, but also for the discharge of rainwater. Finally, a vertical discharge pipe 52 fixedly installed at one end of the S-shaped pipe 51 is connected to the drainage pipe on the exterior wall.

[0026] It should be noted that an air backflow preventer valve 53 is fixedly installed at one end of the vertical pipe 52 located outside the fixed trough box 5 to prevent airflow from entering the interior of the S-shaped pipe body 51 through the vertical pipe 52 and then entering the interlayer.

[0027] Secondly, the vertical pipe 52 maintains a certain distance from the building's exterior decorative aluminum panel 15.

[0028] As another embodiment further provided by this utility model, combined with Figure 3 and Figure 4 As shown, a placement frame 54 is embedded in the port of the fixed trough box 5, and both are on the same horizontal plane, while the port of the planting box 7 is in contact with the side wall of the placement frame 54. This means the placement frame 54 uses negative pressure from the covering layer, which also provides a certain water storage effect. Because when rainfall is heavy, rainwater cannot be drained in time and will overflow from the placement frame 54, the added placement frame 54 is used to prevent the covering layer from overflowing.

[0029] As another embodiment further provided by this utility model, combined with Figure 1As shown, the bottom of the planting box 7 has multiple water inlet holes 71 arranged in a matrix, and the water inlet holes 71 are fixedly connected to the interlayer. The designed water inlet holes 71 facilitate the drainage of liquid from the planting box 7 into the interlayer.

[0030] As another embodiment further provided by this utility model, combined with Figure 1 As shown, the outer side and bottom of the fixed slot box 5 are covered with decorative aluminum plates 14.

[0031] Specifically, the decorative aluminum panel 14 can be assembled with the building exterior wall decorative aluminum panel 15 by expansion screws or assembly methods to increase the towing capacity, that is, the ability to rely on the fixed slot box 5.

[0032] As another embodiment further provided by this utility model, combined with Figure 2 and Figure 4 As shown, it also includes aluminum plate fixing groove brackets 8 that are fixed to the exterior wall by expansion screws and are equidistantly distributed on the same horizontal plane; The aluminum plate fixing groove frame 8 has a U-shaped structure, and fixing bracket hanging grooves 81 are symmetrically arranged on its two side walls along the vertical direction. The side wall of the fixed slot box 5 is symmetrically provided with supporting ribs 9, and the supporting ribs 9 are symmetrically provided with hanging ears 91 along the vertical direction. The hanging ears 91 are fixed to the hanging slot 81 of the fixed bracket.

[0033] Specifically, in addition to the decorative aluminum plate 14 for support, aluminum plate fixing groove brackets 8 are added to both sides of the fixing slot box 5, and the hanging ears 91 are fixed to the fixing bracket hanging grooves 81 as follows. Figure 2 The arrangement shown increases the stability and robustness of the external mounting box 5.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
