[0033] See also Figures 1 to 6 The utility model provides a portable temporary sewage interceptor for a municipal rainwater well, comprising an upper filter element 1 and a lower filter element 2 which can be detachably arranged. The upper filter element 1 is arranged on the wellhead of the rainwater well and its horizontal projection area is larger than the inner diameter of the wellhead of the rainwater well. The lower filter element 2 is arranged in the wellhead of the rainwater well and its outer diameter is smaller than the inner diameter of the rainwater well.

[0034] The upper filter element 1 and the lower filter element 2 are detachably connected via a connecting rod 3 , and a warning sign 4 is detachably provided on the upper end of the connecting rod 3 .

[0035] First, the upper filter element 1 and the lower filter element 2 are connected by the connecting rod 3, and then the lower filter element 2 is placed in the wellhead of the rainwater well. Because its outer diameter is smaller than the inner diameter of the rainwater well, the device can be fixed on the rainwater well more firmly and is not easily washed away by water; the upper filter element 1 is placed on the wellhead of the rainwater well, and because its horizontal projection area is larger than the inner diameter of the wellhead of the rainwater well, it covers the wellhead; finally, a warning sign 4 is detachably provided at the upper end of the connecting rod 3 to alert pedestrians or vehicles.

[0036] The upper filter element 1 and the lower filter element 2 are both basket-like structures formed by weaving metal strips.

The two ends of the lower warning piece 13 on the crossbar 11 are respectively hinged to the upper warning piece 14. When in use, the two upper warning pieces 14 are unfolded so that their movable ends are mutually engaged to form a larger warning area. The foldable design of the warning sign 4 is convenient for storage and carrying when not in use, saving space. At the same time, it can also be directly placed between the upper filter element 1 and the lower filter element 2 without being folded, which is convenient and fast. This design increases the flexibility of use. Whether in storage or in the actual installation process, it can be selected according to specific circumstances. Moreover, when it is directly placed between the upper filter element 1 and the lower filter element 2, it can also avoid the loss of the warning sign 4, and can quickly play a warning role when needed, thereby improving work efficiency and safety.

[0051] Reflectors are provided on both the upper warning sheet 14 and the lower warning sheet 13. The reflectors can reflect light in a dark environment or at night, thereby enhancing the visibility of the warning and further improving safety.

[0052] When the utility model is used, the upper filter element 1 and the lower filter element 2 are first connected by the connecting rod 3, and then the lower filter element 2 is placed in the wellhead of the rainwater well. Because its outer diameter is smaller than the inner diameter of the rainwater well, the device can be fixed on the rainwater well more firmly and is not easily washed away by water; the upper filter element 1 is placed on the wellhead of the rainwater well, and because its horizontal projection area is larger than the inner diameter of the wellhead of the rainwater well, it covers the wellhead; finally, according to actual needs, the heights of the middle rod 8 and the inner rod 9 are adjusted, and the warning sign 4 can be lifted to a certain height to remind pedestrians or vehicles to pay attention and reduce the occurrence of accidents.
