[0033] [First embodiment]

[0034] like Figure 1-10 The overflow well with an opening and closing function provided by the first embodiment of the utility model includes a well body 1, and the outer wall of the well body 1 is respectively provided with a first water inlet 11, a second water inlet 12 and an overflow port 13. The first water inlet 11 is located at the top of the well body 1 and multiple water inlets 11 are evenly provided along the outer circumference of the well body 1. During rainfall, rainwater can pass through the surface soil and enter the well body through the first water inlet 11 to achieve overflow drainage during rainfall. Preferably, a filter grate 2 is installed at the position of the first water inlet 11 to prevent large particles of impurities such as dead branches, fallen leaves and gravel from entering the well body 1. The second water inlet 12 is located on one side of the bottom of the well body 1. Water in the surrounding installation environment can pass through the deep soil layer and enter the well body 1 through the second water inlet 12 to achieve daily drainage. The overflow port 13 is located on the other side of the bottom of the well body 1 to achieve overflow drainage.

[0035] A manhole cover assembly 3 and a float assembly 4 are provided inside the well body 1. The float assembly 4 is fixedly connected to the bottom of the manhole cover assembly 3, and the float assembly 4 can follow the rise and fall of the liquid level inside the well body 1 to drive the manhole cover assembly 3 to rise and fall synchronously, thereby achieving: during daily drainage, the float assembly 4 is located at a low position inside the well body 1, the manhole cover assembly 3 is closed, and the water body passes through the deep soil layer through the second water inlet 12 into the well body 1 and is then discharged through the overflow port 13 to achieve daily drainage; during rainfall drainage, rainwater passes through the surface soil through the first water inlet 11 into the well body, and the float assembly 4 rises synchronously with the liquid level height inside the well body 1 until it reaches a high position, the manhole cover assembly 3 is opened, and a large flow of rainwater directly enters the well body 1 through the first water inlet 11 and is then discharged through the overflow port 13 to achieve overflow drainage during rainfall.

[0036] like Figure 1 As shown, in this embodiment, a bracket 14 is provided in the middle of the shell 1, and the manhole cover assembly 3 is located on the top of the bracket 14. When the liquid level height inside the well body 1 is not high enough to float the float assembly 4, the top manhole cover assembly 3 is supported by the bracket 14.

[0037] In this embodiment, the manhole cover assembly 3 includes a planting space 31 and a manhole cover body 32 located at the bottom of the planting space 31. The bottom of the planting space 31 and the top of the manhole cover body 32 are fixedly connected. The planting space 31 can be filled with a planting soil layer and green plants, and the green plants are planted inside the planting space 31 through the planting soil layer; and the outer wall of the manhole cover body 32 is evenly provided with a plurality of water holes 321. In the open state, the manhole cover body 32 is located at the height of the first water inlet 11, and a large flow of rainfall and rainwater can pass through the plurality of water holes 321 into the well body 1. Preferably, the planting space 31 and the manhole cover body 32 in this embodiment can be set to a symmetrical structure up and down, which is convenient for manufacturing and has a beautiful appearance, and can ensure the overall quality balance. For example, the planting space 31 can be set to an open slot shape with a large top and a small bottom, and the manhole cover body 32 can be set to an open slot shape with a small top and a large bottom.

[0038] The float assembly 4 includes a float 42 and a connecting rod 41. The float 42 is located at the bottom of the bracket 14. The top of the float 42 is fixedly connected to one end of the connecting rod 41, and the other end of the connecting rod 41 is fixedly connected to the manhole cover assembly 3. Therefore, when the liquid level inside the well body 1 rises and falls, the top manhole cover assembly 3 is driven to open and close through the float assembly 4.

[0039] During daily drainage, the float assembly 4 is located at a low position inside the well body 1, the well cover assembly 3 is closed, and the water passes through the deep soil layer and enters the well body 1 through the second water inlet 12 and then is discharged through the overflow port 13 to achieve daily drainage. Figure 6 As shown;

[0040] At the beginning of rainfall, rainwater passes through the surface soil and enters the well body through the first water inlet 11. The float assembly 4 rises synchronously with the liquid level in the well body 1. Figure 7 As shown;

[0041] When the float assembly 4 rises synchronously with the liquid level in the well body 1 and reaches the high level, it drives the well cover assembly 3 to open, and a large amount of rainwater directly enters the well body 1 through the first water inlet 11 and is discharged through the overflow port 13 to achieve overflow drainage during rainfall. Figure 8 shown.

[0042] like Figure 9-10 The figure shows the application structure diagram of the overflow well provided by this embodiment in the actual installation environment. During daily drainage, the well cover assembly 3 is closed, and the water passes through the deep soil layer through the second water inlet 12 into the well body 1 and then is discharged through the overflow port 13 to achieve daily drainage. Fig. 9 As shown; when it rains, rainwater passes through the surface soil and enters the well body through the first water inlet 11. The float assembly 4 rises synchronously with the liquid level height inside the well body 1 until it reaches a high level, driving the well cover assembly 3 to open. A large amount of rainwater directly enters the well body 1 through the first water inlet 11 and is then discharged through the overflow port 13 to achieve overflow drainage during rainfall, as shown in 10.
