Due to the influence of factors such as weather and sanitation cleaning methods, there are usually garbage such as leaves, plastic bags, and sediment inside the rainwater outlets, which can easily cause the rainwater outlets to be blocked. At the same time, the water flow formed by rainwater will bring some sediment, silt and solid garbage into the rainwater connecting pipe of the rainwater outlet facilities, gradually forming siltation of sediment and garbage in the pipe. In severe cases, it will even completely block the rainwater drainage pipe, thereby paralyzing the local rainwater drainage system and almost losing the drainage function, causing waterlogging in urban blocks and rainwater backflow in residential areas, which will have an adverse impact on the transportation system of the town and the daily life of urban residents and property losses.

[0032] As a preferred embodiment, the lily leaf seal 20 is connected to the main frame 10 through a connecting assembly 30, and the connecting assembly 30 includes a first connecting mechanism 310, a second connecting mechanism 320 and a third connecting mechanism 330, wherein the first connecting mechanism 310 is connected to the bottom of the lily leaf seal 20, the second connecting mechanism 320 is connected to the bottom of the main frame 10, and the third connecting mechanism 330 is connected between the first connecting mechanism 310 and the second connecting mechanism 320.

[0033] As a preferred embodiment, Figure 5 As shown, the first connecting mechanism 310 includes a middle arch section 311 with an upward opening and two side horizontal sections 312 respectively connected to the two ends of the middle arch section 311, each of the side horizontal sections 312 is provided with a first vertical bolt hole (not shown) for the first bolt 313 to pass through, and the main frame 10 is provided with a second vertical bolt hole (not shown) arranged corresponding to the first vertical bolt hole, and the side horizontal section 312 is connected to the main frame 10 by the first bolt 313 passing through the first vertical bolt hole and the second vertical bolt hole, and the middle arch section 311 is connected to the third connecting mechanism 330.

[0034] As a preferred embodiment, Figure 3-4As shown, the third connection mechanism 330 is an L-shaped rib 331, and the L-shaped rib 331 includes a fixed end 3311 and a movable end 3312. The fixed end 3311 is connected to the second connection mechanism 320, and the movable end 3312 is hinged to the middle arch section 311. As a preferred example, the fixed end 3311 and the second connection mechanism 320 can be integrally formed, such as Figure 5 As shown, the movable end 3312 and the middle arch section 311 are hinged by setting a movable end bite arm 3111 on the middle arch section 311, and a bite structure 3313 is correspondingly set on the movable end 3312 of the L-shaped rib 331. The movable connection between the L-shaped rib 331 and the middle arch section 311 is realized by the cooperation of the bite structure 3313 and the movable end bite arm 3111. The movable connection method can facilitate the installation and disassembly of the lily leaf seal 20, for example, it can realize local adjustment operations.

[0035] Furthermore, if Figure 1 As shown, the second connection mechanism 320 is a connection spoke 321, the connection spoke 321 is connected to the main frame 10, and the fixed end 3311 is connected to the connection spoke 321.

[0039] Further, the number of the lily leaf seals 20 is multiple, and the multiple lily leaf seals 20 are evenly spaced and arranged along the width direction of the main frame 10. Specifically, the number of the lily leaf seals 20 can be set by those skilled in the art according to actual needs. In a specific example, the number of the lily leaf seals 20 is set to 5, and the 5 lily leaf seals 20 are evenly spaced and arranged along the width direction of the main frame 10.

[0040] Furthermore, if Figure 1 As shown, the number of the connecting spokes 321 is two, each of which extends along the width direction of the main frame 10, and the two connecting spokes 321 are oppositely arranged on both sides of the lily leaf seal 20. Under this structure, both ends of each lily leaf seal 20 are connected to the corresponding connecting spokes 321 through the connecting assembly 30, so that the installation reliability of the lily leaf seal 20 can be ensured.
