Description

Technical Field

[0001] The utility model relates to the technical field of sponge city sunken green space drainage, in particular to a sunken green space drainage structure for sponge city construction. Background Art

[0002] In the construction of sponge cities, sunken green spaces refer to green spaces that are less than 200mm below the surrounding paved ground or roads. The depth of the sunken green space should be determined based on the flood resistance of the plants and the soil permeability. An overflow drainage structure should generally be set up in the sunken green space to ensure the overflow discharge of runoff during heavy rains. The top elevation of the overflow drainage structure should generally be a certain distance higher than the green space. The function of the overflow drainage structure is to drain excess rainwater when the rainfall is greater than the depth of the sunken cavity.

[0003] The utility model with the existing authorization announcement number CN217128444U discloses a sunken green space drainage structure for sponge city construction, including an underground drainage pipe and an overflow pipe vertically fixed and connected to the upper end of the underground drainage pipe. A shell is provided at the upper end of the overflow pipe, and the upper end of the overflow pipe is fixedly connected to the middle part of the lower end of the shell. The bottom of the shell is located on the left and right sides of the overflow pipe and is set as an inclined surface.

[0004] By adopting the above technical scheme, the drainage can be automatically performed when needed, with a long service life and a reliable structure. It is easy to clear the debris blocked between the trash racks, which saves time, labor and efficiency. However, in the above technical scheme, when the sponge city sunken green space drainage structure is in use, there is a certain distance between the overflow port of the drainage structure and the green space. When heavy rain occurs, the water absorption rate of the green space reaches saturation, and a large amount of rainwater is easily accumulated in the gap between the overflow port of the drainage structure and the green space, which cannot be discharged in time, causing a large number of green plants with shorter plants to die due to blisters, reducing the vegetation diversity of the sponge city sunken green space, and also greatly affecting the drainage effect of the sponge city sunken green space drainage structure.

[0024] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the sunken green space drainage structure for sponge city construction of the utility model in conjunction with the accompanying drawings.

[0025] See also Figure 1-4 The utility model is a sunken green space drainage structure for sponge city construction, comprising a green space main body 1, a sewer pipe 2 and a drainage pipe 3. The drainage pipe 3 and the sewer pipe 2 are both located inside the green space main body 1. The bottom end of the drainage pipe 3 penetrates the sewer pipe 2 and extends to the inside of the sewer pipe 2. The outer surface of the drainage pipe 3 is provided with overflow ports 4 arranged at equal distances. A microporous filter plate 5 is arranged inside the drainage pipe 3. A conical frame 6 is fixedly connected to the outer surface of the drainage pipe 3. The conical frame 6 is clamped inside the green space main body 1. The outer surface of the drainage pipe 3 is fixedly provided with drainage ports 7 arranged at equal distances. Each drainage port 7 is fixedly provided with a conical frame 6. The water inlets 7 are all located inside the conical frame 6, and an electric push rod 8 is provided inside the drain pipe 3. The telescopic end of the electric push rod 8 is fixedly connected to a mobile frame 9, and eight connecting plates 10 are fixedly connected to the outer surface of the mobile frame 9. Each connecting plate 10 is slidably connected to the inside of the drain pipe 3, and a side of each connecting plate 10 away from the mobile frame 9 is fixedly connected to a hollow tube 11, and each hollow tube 11 is located inside the conical frame 6. The outer surface of each hollow tube 11 is provided with drainage holes 12 arranged at equal distances, and the top of each hollow tube 11 penetrates the conical frame 6 and extends to the inside of the conical frame 6.

[0026] The inner wall of the drain pipe 3 is fixedly connected with a limiting ring 13, and the upper surface of the limiting ring 13 contacts the bottom surface of the microporous filter plate 5. The limiting ring 13 can limit the position of the microporous filter plate 5 inside the drain pipe 3, so that the microporous filter plate 5 can maintain a suitable height inside the drain pipe 3, thereby improving the reliability of the use of the microporous filter plate 5.

[0027] Two connecting columns 14 are fixedly connected to the upper surface of the microporous filter plate 5, and a pull ring 15 is fixedly connected to the top of each connecting column 14. The pull ring 15 cooperates with the connecting column 14 to facilitate the staff to manually pull the microporous filter plate 5 out of the drain pipe 3, thereby facilitating the staff to clean and replace the microporous filter plate 5, thereby increasing the convenience of maintenance of the microporous filter plate 5.

[0028] A reinforcement ring 16 is fixedly connected to the upper surface of the conical frame 6, and the inner wall of the reinforcement ring 16 is fixedly connected to the outer surface of the drain pipe 3. The reinforcement ring 16 can increase the connection firmness between the conical frame 6 and the drain pipe 3, making it difficult for the conical frame 6 to loosen from the drain pipe 3, thereby increasing the reliability of the use of the conical frame 6.

[0029] A protective cover 17 is fixedly connected to the upper surface of the conical frame 6, and the inner wall of the protective cover 17 is fixedly connected to the outer surface of the drain pipe 3. The outer surface of the protective cover 17 is provided with water inlet grooves 18 arranged at equal distances. The protective cover 17 cooperates with the water inlet grooves 18 to allow rainwater to flow smoothly into the protective cover 17 while effectively isolating external garbage such as branches and leaves, thereby preventing the conical frame 6 from accumulating too many impurities and affecting the smooth progress of subsequent drainage work.

[0030] The bottom end of the electric push rod 8 is fixedly connected to a support frame 19, and the outer surface of the support frame 19 is fixedly connected to the inner wall of the drain pipe 3. The support frame 19 can support and fix the position of the electric push rod 8, so that the electric push rod 8 can smoothly drive the moving frame 9 to move up and down, ensuring the normal operation of the electric push rod 8.

[0031] The bottom surface of each connecting plate 10 is fixedly connected with a reinforcing rib 20, and the side surface of each reinforcing rib 20 close to the movable frame 9 is fixedly connected to the outer surface of the movable frame 9. The reinforcing rib 20 can increase the connection tightness between the connecting plate 10 and the movable frame 9, make the connection between the connecting plate 10 and the movable frame 9 less prone to bending and deformation, and increase the pressure bearing capacity of the connecting plate 10.

[0032] The top of each hollow tube 11 is fixedly connected with a rubber plug 21, and the bottom surface of each rubber plug 21 is in contact with the upper surface of the conical frame 6. The rubber plug 21 can close the gap between the hollow tube 11 and the conical frame 6 when the hollow tube 11 is used for drainage, thereby ensuring that the sunken green space can smoothly absorb and store water when it rains lightly.

[0033] The working principle of the utility model is as follows: firstly, the electric push rod 8 is connected to the power supply. In the case of heavy rain, the accumulated water on the green space main body 1 accumulates rapidly and the water level exceeds the overflow port 4. The accumulated water can smoothly pass through the overflow port 4 and the drain pipe 3 into the sewer pipe 2. Under the limit of the limit ring 13, the microporous filter plate 5 can filter the rainwater entering the drain pipe 3 to prevent impurities from clogging the drain pipe 3 and the sewer pipe 2. When the height difference between the overflow port 4 and the green space main body 1 after the heavy rain reaches saturation due to the water absorption of the green space main body 1 and the accumulated rainwater needs to be drained, the power provided by the electric push rod 8 cooperates with the support frame 19 to push the moving frame 9 up and down, and then push the connecting plate 10 to move up and down inside the drain pipe 3. At this time, the connecting plate 10 can push the hollow tube 11 to move upward until the drainage hole 12 exposes the conical frame 6. The main body 1 of the ground is parallel, and the accumulated water between the overflow port 4 and the main body of the green space 1 will be filtered by the protective cover 17 and the water inlet trough 18, and then enter the conical frame 6 through the drainage hole 12 and the hollow tube 11, and then be discharged from the sewer pipe 2 through the drainage port 7 and the drainage pipe 3, so that the sponge city sunken green space drainage structure can discharge the accumulated water in the gap between the overflow port 4 and the green space in time, and prevent the large-scale death of shorter green space plants due to blisters, thereby ensuring the diversity of sponge city sunken green space vegetation and the overall drainage effect of the sponge city sunken green space drainage structure. Finally, by using the contraction of the electric push rod 8, the hollow tube 11 can be driven to retract into the conical frame 6 in cooperation with the movable frame 9 and the connecting plate 10, and at the same time, the rubber plug 21 closes the gap between the hollow tube 11 and the conical frame 6, so that when it rains lightly, the sunken green space can be guaranteed to smoothly absorb and store water.
