[0002] In recent years, with the continuous development of sponge city technology, many cities have actively infiltrated sponge technology into the construction of municipal projects. One of the contents is to install overflow wells in green belts. Specifically, the overflow well is raised to 5 to 10 cm above the top surface of the green belt. After the green belt is fully saturated with water, the excess rainwater flows into the overflow well and then into the drainage system or water storage system. At present, most overflow wells are based on practicality. The structure is similar to the lid-shaped rainwater grate. The overflow wells in the green belt have no odor-proof function, and odors overflow from time to time. Floating objects such as fallen leaves can easily block the overflow port along the water flow, affecting the drainage effect. Utility Model Content

[0021] See Figure 1 、 Figure 2 As shown, in a preferred embodiment, the automatic opening and closing anti-odor and anti-clogging overflow device of the present utility model includes a device body located in the green belt and symmetrically arranged on both sides of the green belt centerline 1. The device body includes an overflow well 2, the wellhead of which is higher than the top surface 3 of the green planting soil. The top of the overflow well 2 is provided with a manhole cover 4 with an automatic opening and closing opening. The overflow well 2 is surrounded by a blocking fence, the height of which is higher than the height of the manhole cover 4.

[0022] Continuing to refer to the figure, the manhole cover 4 is a raised hemispherical shape, and is provided with fan-shaped rotating blades 5 and fixed blades 6. The rotating blades 5 and the fixed blades 6 are arranged at intervals, and the total number of blades can be set to eight blades, ten blades, etc. according to actual needs.

[0023] A water level sensor 7 is provided on the outer edge of the wellhead of the overflow well 2. Figure 3As shown, the water level sensor 7 has a high water level trigger point 8 and a low water level trigger point 9. The manhole cover 4 is equipped with a solar cell 10 and a solar motor 11. The solar cell 10, solar motor 11, and rotating blades 5 are connected in sequence, and the water level sensor 7 is connected to the solar motor 11. When the water level reaches the high water level trigger point 8, the water level sensor 7 sends a signal, and the solar motor 11 drives the rotating blades 5 to rotate, the manhole cover 4 is opened, and water flows into the overflow well 2. As the water level drops to the low water level trigger point 9, the solar motor 11 drives the rotating blades 5 to rotate again, and the manhole cover 4 is closed, preventing odors from the well from escaping.

[0024] The blocking fence is formed into a hexagon by an end fence 12 and a node fence 13 enclosed by a wire fence 14, and the end fence 12 is located on the center line 1 of the green belt.

[0025] The water-facing surface of the transverse cross-section of the end fence 12 is arc-shaped and tangent to the wire fence 14, which plays a water diversion role and prevents floating objects such as fallen leaves from clogging the wire fence 14 with the water flow. The end angle α of the blocking fence is set according to the radius of the manhole cover 4 and the width of the green belt, preferably 60° to 90°.

[0026] In addition, the spherical surface of the manhole cover 4 can be decorated with paint or the like into an object that is in harmony with the green belt landscape. For example, it can be decorated with color pigments into watermelons, cacti, succulents, and other objects that match the landscape effect of the dividing zone to create a landscape effect.

[0027] This device automatically opens and closes. When open, it quickly drains accumulated rainwater runoff from the green belt. When closed, it blends seamlessly into the landscape, simultaneously blocking the spread of odors in drainage pipes. A barrier barrier around the perimeter prevents floating debris like fallen leaves from clogging drainage facilities. This device is simple to construct and requires minimal maintenance. Its strong drainage capacity significantly reduces rainwater runoff, prevents the spread of odors and clogging pipes, and contributes to disaster prevention and mitigation, improving urban quality, and possesses excellent promotional value.

[0028] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
