Description

Technical Field

[0001] This utility model relates to the field of sponge city drainage technology, specifically a sponge city drainage design structure. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept. It refers to a city's ability to function like a sponge, exhibiting good resilience in adapting to environmental changes and responding to natural disasters caused by rainwater. When it rains, it absorbs, stores, infiltrates, and purifies water; when needed, it releases and utilizes the stored water, allowing rainwater to migrate freely within the city. Sponge city construction should adhere to principles such as ecological priority, combining natural methods with artificial measures to maximize the accumulation, infiltration, and purification of rainwater in urban areas while ensuring urban drainage and flood control safety, thus promoting rainwater resource utilization and ecological environmental protection. However, existing urban drainage wells require the manhole covers to be fully opened when rapidly draining water from roads, which can easily lead to safety hazards.

[0003] Based on this, a sponge city drainage design structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] 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.

[0024] In one embodiment, such as Figures 1-5 As shown, a sponge city drainage design structure includes a manhole cover 1 and a drainage well 4. The manhole cover 1 has a drainage hole 2. The bottom of the drainage well 4 is connected to a sewer pipe 14. The top of the manhole cover 1 has a rotating groove 8. A rotating wheel 3 is rotatably connected in the rotating groove 8. The bottom of the rotating wheel 3 is connected to an adjustment mechanism.

[0025] In this embodiment, by setting the adjustment mechanism, when the city needs to drain a large amount of water, the operator can rotate the wheel 3 to control the adjustment mechanism to raise the manhole cover 1 to increase the drainage volume, without having to fully open the manhole cover 1, thus reducing safety hazards.

[0026] In one embodiment, such as Figure 4 As shown, the adjustment mechanism includes a threaded sleeve 9, a limiting sleeve 10, a fixing plate 13, a threaded rod 11, and a limiting rod 12. The threaded sleeve 9 is rotatably connected to the rotating wheel 3 at the center of the rotating groove 8. The top end of the limiting sleeve 10 is fixedly connected to the manhole cover 1. The inner wall of the drainage well 4 is fixedly connected to the fixing plate 13. The threaded rod 11 is fixedly connected to the center of the fixing plate 13. The threaded rod 11 and the threaded sleeve 9 are threadedly connected. A pair of limiting rods 12 are fixedly connected to the top of the fixing plate 13. The limiting rods 12 are slidably connected to the limiting sleeve 10. Rotating the rotating wheel 3 causes the threaded sleeve 9 to rotate, which in turn lifts the manhole cover 1. The limiting rods 12 can restrict the manhole cover 1 from rotating with it.

[0027] In one embodiment, such as Figure 4 As shown, the top of the fixing plate 13 is provided with a slope 23, which can prevent residue to a certain extent;

[0028] In one embodiment, such as Figure 4 As shown, a rotating component 7 is provided on one inner wall of the rotating wheel 3, and a handle 6 is connected to the rotating component 7. The handle 6 is designed to facilitate the operator to rotate the wheel. When the rotating wheel 3 is not in use, the handle 6 can be folded and stored inside the rotating wheel 3.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom of the manhole cover 1 is provided with a filter groove 5. When the manhole cover 1 is opened, the filter groove 5 can block large debris from the outside and prevent blockage in the pipe.

[0030] In one embodiment, such as Figure 3 As shown, the bottom side of the drain pipe 14 is connected to the main drain 15, and one side of the drain pipe 14 is connected to the emergency drain 16. When too much water accumulates in the drain pipe 14, it can be discharged through the emergency drain 16 to prevent untimely drainage.

[0031] In one embodiment, such as Figure 3 As shown, a sealing mechanism is provided at the connection between the emergency drainage channel 16 and the sewer pipe 14. Under normal drainage conditions, the emergency drainage channel 16 remains closed.

[0032] In one embodiment, such as Figure 5 As shown, the sealing mechanism includes a pair of limiting slide grooves 17, which are fixedly connected to the drain pipe 14. A limiting bottom plate 21 is fixedly connected between the bottom of the two limiting slide grooves 17, and a limiting top plate 22 is fixedly connected between the two limiting slide grooves 17. A sealing plate 18 is slidably connected to the inner wall of the limiting slide groove 17. A float plate 20 is fixedly connected to the outer side of the sealing plate 18, and a float cylinder 19 is fixedly connected to the outer side of the float plate 20. When the main drainage channel 15 cannot meet the drainage requirements, the water accumulates in the drain pipe 14 to a certain height, which will generate buoyancy and push the sealing plate 18 through the float cylinder 19, automatically opening the emergency drainage channel 16, realizing flexible adjustment of drainage volume and preventing road water accumulation due to untimely drainage.

[0033] The above embodiment discloses a sponge city drainage design structure, wherein the drainage hole 2 is used for daily drainage. When the city needs to drain a large amount of water, the operator rotates the rotating wheel 3 to rotate the threaded sleeve 9 and drive the manhole cover 1 to rise. The limiting rod 12 can limit the manhole cover 1 from rotating, thereby adjusting the drainage volume without having to fully open the manhole cover 1. The handle 6 is designed to facilitate the operator to rotate the rotating wheel 3. When the rotating wheel 3 is not needed, the handle 6 can be folded and stored inside the rotating wheel 3. When the manhole cover 1 is open, the filter groove 5 can block large debris and prevent blockage in the pipe. When the main drainage channel 15 cannot meet the drainage requirements, the water accumulates in the sewer pipe 14 to a certain extent, and the closed sealing plate 18 will be automatically opened by the float 19 to open the emergency drainage channel 16. Under normal drainage conditions, the emergency drainage channel 16 remains closed, realizing flexible adjustment of the drainage volume and preventing road water accumulation due to untimely drainage.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
