Description

Technical Field

[0001] This utility model relates to the technical field of sponge city regulation devices, specifically to a prefabricated time-delay regulation device with drainage function for use in sponge cities. Background Technology

[0002] Sponge city is a new concept in urban stormwater management, aiming to make cities resilient like sponges, adapting to environmental changes and responding to natural disasters caused by rainwater. Sponge cities can absorb, store, infiltrate, and purify rainwater during rainfall, and release and utilize the stored water when needed, thereby achieving the goal of protecting and improving the urban ecological environment.

[0003] Existing sponge cities often require the installation of delayed sewage discharge devices to achieve the effect of delayed sewage discharge. However, existing delayed sewage discharge devices often use underground installations and lack measures to deal with urban flooding caused by rainwater backflow during heavy rainfall. At the same time, due to different application environments, existing delayed sewage discharge devices often need to be designed with different sizes to meet sewage discharge requirements, which is time-consuming, costly, and has a narrow range of applications.

[0004] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention

[0005] In order to address the defects and shortcomings of existing technologies, this utility model provides a prefabricated time-delay adjustment device with drainage function for use in sponge cities.

[0006] The specific solution provided by this utility model is as follows:

[0007] A prefabricated time-delay adjustment device with drainage function for use in sponge cities includes a box body, characterized in that: a front side plate and a rear side plate are fixed to the front and rear sides of the box body respectively, and a water storage space is formed between the box body, the front side plate and the rear side plate; a cover plate and a seepage plate are fixed to the top of the box body from top to bottom respectively; a rainwater drainage pipe is laid between the cover plate and the seepage plate, and rainwater can pass through the cover plate and the seepage plate into the interior of the water storage space; a slow-release device connected to the rainwater pipe and a sewage discharge device connected to the sewage pipe are respectively installed inside the water storage space.

[0029] [First Embodiment]

[0030] like Figure 1-6 The image shows a prefabricated time-delay adjustment device with drainage function for use in sponge cities, as provided in the first embodiment of this utility model. Figure 2 As shown, the device includes a box body 1, with a front side panel 2 and a rear side panel 3 fixed to the front and rear sides of the box body 1, respectively. The box body 1, the front side panel 2, and the rear side panel 3 form a water storage space.

[0031] The top of the box 1 has a first groove 11 and a second groove 12 for installing the cover plate 4. The cover plate 4 and the leakage plate 5 are fixed from top to bottom on the top of the box 1 through the first groove 11 and the second groove 12. A drain pipe 8 is laid between the cover plate 4 and the leakage plate 5. Correspondingly, a front mounting hole 21 for passing through one end of the drain pipe 8 is opened on the front side plate 2, and a rear mounting hole 31 for passing through the other end of the drain pipe 8 is opened on the rear side plate 3. The drain pipe 8 passes through the front mounting hole 21 and the rear mounting hole 31 and is set between the cover plate 4 and the leakage plate 5.

[0032] The cover plate 4 has a plurality of uniformly distributed through holes 41, which are oblong in shape. Similarly, the permeable plate 5 has a plurality of uniformly distributed permeable plates 51, which are circular in shape. This allows rainwater to pass through the cover plate 4 and the permeable plate 5 into the water storage space. In this embodiment, the diameter of the permeable plates 51 is smaller than that of the through holes 41. This design allows large particles entering through the through holes 41 to be blocked by the smaller-diameter permeable plates 51 and remain between the cover plate 4 and the permeable plate 5. These particles can then be drained through the rainwater drain pipe 8 and flushed to the subsequent filtration device. Alternatively, filtration devices can be added to both ends of the rainwater drain pipe 8 to allow large particles to remain between the cover plate 4 and the permeable plate 5 and be removed through subsequent periodic treatment. This prevents large particles from entering the water storage space and causing unintended damage to the slow-release device 6 and the sewage discharge device 7.

[0033] Inside the water storage space, there are a slow-release device 6 connected to the rainwater pipe 61 and a sewage discharge device 7 connected to the sewage pipe 71. Correspondingly, the bottom of the box body 1 is provided with a rainwater installation hole 13 for passing through the rainwater pipe 61 and a sewage installation hole 14 for passing through the sewage pipe 71. In this embodiment, the diameter of the sewage installation hole 14 is larger than the diameter of the rainwater installation hole 13 to meet the requirements of preventing large particulate impurities from getting dirty.

[0034] Preferably, the sustained-release device 6 in this embodiment is a non-powered sustained-release device, such as the one mentioned in our patent application with publication number CN210737732U. The sewage discharge device 7 is a non-powered sewage discharge device, such as the one mentioned in our patent application with publication number CN110306641B.

[0035] The specific working process of this embodiment is as follows:

[0036] During normal rainfall, such as Figure 3 As shown, rainwater flows in through the cover plate 4 and then through the infiltration plate 5 into the water storage space to form a water level. As the water level inside the water storage space continues to rise, the slow-release device 6 starts to work, and the water after slow-release treatment flows into the rainwater pipe 61.

[0037] If rainfall intensifies and heavy rainfall occurs, such as Figure 4 As shown, when the water level inside the water storage space continues to rise until it exceeds the position of the infiltration plate 5 at the top of the water storage space, the rainwater flowing in from the cover plate 4 will be directly discharged into the rainwater well through the rainwater drain pipe 8.

[0038] When the rainfall ends, the continued operation of the slow-release device 6 will cause the water level inside the storage space to drop continuously, such as... Figure 5 As shown; when the water level inside the water storage space drops to the designated position, the sewage discharge device 7 starts working to discharge the remaining water inside the water storage space through the sewage pipe 71. At this time, as... Figure 6 As shown.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
