[0028] The limiting assembly can also comprise at least two limiting rods 12 which are respectively hinged on the side wall of the fixing rod 10 in symmetrical distribution through the connecting plate 14, the fixing plate 7 is provided with a through hole for the fixing rod 10 and the limiting rod 12 to pass through, the inner side wall of the top end of the limiting rod 12 outside the through hole is fixed with a spring 11, and the outer side wall is fixed with a stop block 13 for preventing the limiting rod 12 from falling into the water collecting cylinder 1, and the through hole opening near the stop block 13 side is in a circular arc structure;

[0029] The length of the part of the limiting rod 12 below the connecting plate 14 is less than the length of the part above the connecting plate 14, so that the limiting rod 12 and the fixing plate 7 can be fixed when the sealing plate 5 is downward, avoiding the water flow from pulling the sealing plate 5 upward when the water collecting cylinder 1 sinks into the water.

[0030] The outer side wall of the sealing plate 5 is in an inclined surface with high inside and low outside, and the bottom of the fixing plate 7 is provided with an annular groove which closely matches it, which is convenient for improving the sealing effect, making the sealing plate 5 and the fixing plate 7 more closely and stably matched.

[0031] The inner diameter of the water collecting cylinder 1 gradually decreases from bottom to top, the sealing block 3 is fixed at the bottom of the sealing plate 5, and the sealing block 3 is a hollow hemispherical structure as a whole, the opening end of the sealing block 3 is buckled at the bottom of the sealing plate 5, and when the sealing plate 5 and the fixed plate 7 are tightly attached, the outer side wall of the sealing block 3 is tightly attached to the inner side wall of the water collecting cylinder 1, so that the water flow entering the water collecting cylinder 1 can more quickly and stably lift the sealing plate 5 upward, and when the sealing plate 5 is lifted upward by the water flow and attached to the fixed plate 7, the sealing block 3 is attached to the inner side wall of the water collecting cylinder 1, which further improves the sealing effect;
