Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sponge city technology, and in particular relates to a sponge balcony. Background Technology
[0002] A sponge city refers to a city that, like a sponge, has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and when needed, it releases and utilizes the stored water. As a major means of urban flood control, sponge cities play a very important role in reducing urban rainwater at its source.
[0003] In the construction of sponge cities, the increased development investment means that the effects are not immediately visible. Furthermore, sponge cities are a systematic and planned concept, and the results cannot be seen instantly from a single facility or piece of equipment. Therefore, construction faces significant obstacles, especially in the renovation of old residential areas. Integrating it with other existing facilities would save investment and promote mutual improvement, representing a current development direction. Secondly, regarding green building construction, many existing building renovation projects cannot be made green due to objective reasons, leaving a gap in green building practices within existing building renovation projects. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a sponge balcony, which aims to solve the problems mentioned in the background art.
[0005] This utility model embodiment is implemented as follows: a sponge balcony, including a rainwater flower box, and further comprising:
[0006] A planting module, which is located in the upper middle part of the rainwater flower box, is used for planting plants;
[0007] A rainwater harvesting module includes a water inlet pipe and a float. The water inlet pipe is located on the lower side wall of the rainwater garden box and connected to the rainwater pipe. A water inlet baffle is hinged to the side of the water inlet pipe near the rainwater pipe, and the water inlet baffle is in a horizontal state when no external force is applied. The float is located inside the rainwater garden box. The rainwater garden box is connected to a rope, and the end of the rope away from the float is connected to the water inlet baffle.
[0008] In a further technical solution, the rainwater collection module also includes an overflow pipe located in the upper middle part of the side wall of the rainwater flower box.
[0009] In a further technical solution, the planting module includes a grid plate, which is positioned above the overflow pipe. A pebble layer is provided on the grid plate, a geotextile is provided on the pebble layer, and planting soil is provided on the geotextile.
[0010] In a further technical solution, the grating is made of steel and has a thickness of 40mm.
[0011] In a further technical solution, the thickness of the pebble layer is 50mm, and pebbles with a diameter of 30-50mm are selected.
[0012] This utility model provides a sponge balcony. During the initial stages of rainfall or when rainfall is light, rainwater from the roof is discharged through rainwater pipes. Some rainwater is intercepted by water-receiving baffles on each floor as it flows through the pipes, and then transported to rainwater collection boxes. When rainfall is prolonged or heavy, and the collection box's capacity exceeds its limit, a float rises due to buoyancy, pulling on the rope connected to the float. The rope then lifts the water-receiving baffles, blocking the water-receiving pipes and preventing further rainwater from entering the collection box. Through integrated design, rainwater is intercepted at each floor, achieving the source reduction effect of a sponge city. The rainwater collection boxes installed on each floor and in each household beautify the environment and comply with the requirements of sponge cities and green buildings.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] like Figures 1-4As shown, a sponge balcony according to one embodiment of the present invention includes a rainwater flower box 2, and further includes:
[0021] A planting module is located in the upper middle part of the rainwater flower box 2 and is used for planting plants.
[0022] The rainwater collection module includes a water inlet pipe 3 and a float 5. The water inlet pipe 3 is located on the lower side wall of the rainwater collection box 2 and is connected to the rainwater pipe 1. A water inlet baffle 4 is hinged to the side of the water inlet pipe 3 near the rainwater pipe 1. When no external force is applied, the water inlet baffle 4 is in a horizontal (or slightly tilted upward) state. The float 5 is located inside the rainwater collection box 2. The rainwater collection box 2 is connected to a rope 6, and the end of the rope 6 away from the float 5 is connected to the water inlet baffle 4.
[0023] In this embodiment of the invention, during use, the rainwater flower box 2 is first installed near the rainwater pipe 1 on each floor and in each household, similar to the installation of an air conditioner, forming a sponge balcony. Then, the rainwater pipe 1 is modified by disconnecting and connecting it to the water inlet pipe 3. At the beginning of rain (or when the rainfall is light), rainwater from the roof is discharged through the rainwater pipe 1. Some of the rainwater is intercepted by the water inlet baffles 4 on each floor as it flows through the rainwater pipe 1, and then transported to the rainwater flower box 2 through the water inlet pipe 3. When the rain lasts for a long time or the rainfall is heavy, and the water storage capacity of the rainwater flower box 2 exceeds its capacity, the float 5 rises due to buoyancy, pulling the rope 6 connected to the float 5. The rope 6 pulls up the water inlet baffle 4, thereby blocking the water inlet pipe 3, and rainwater can no longer enter the rainwater flower box 2.
[0024] The above integration achieves rainwater interception at each floor, realizing the role of source reduction in sponge city construction. The rainwater flower boxes installed in each floor and household not only beautify the environment but also realize sponge city and green building concepts.
[0025] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the rainwater collection module further includes an overflow pipe 7 disposed in the upper middle part of the side wall of the rainwater flower box 2, for draining excess water.
[0026] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the planting module includes a grid plate 8, which is disposed above the overflow pipe 7. A pebble layer 9 is disposed on the grid plate 8, a geotextile 10 is disposed on the pebble layer 9, and planting soil 11 is disposed on the geotextile 10.
[0027] In this embodiment of the utility model, the grating plate 8 is made of steel and has a thickness of 40mm; the pebble layer 9 has a thickness of 50mm and uses pebbles with a diameter of 30-50mm.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
