The first sealing assembly comprises a first sealing strip 2; the second sealing assembly comprises a second sealing strip 3.
As shown in fig. 12 and 13, the second sealing tape 3 includes a vertical first mating surface 31, a second mating surface 32 extending vertically inward along the bottom of the first mating surface 31, and a third mating surface 33 extending vertically downward along the inside of the second mating surface 32. The second mating surface 32 and the third mating surface 33 are sealing mating surfaces of the second sealing strip 3 and the weir crest flow channel.
As shown in fig. 1, 2, 3, 5 and 8, the first sealing strip 2 and the second sealing strip 3 are in end contact, wherein the bottom end surface of the first sealing strip 2 is flush with the downward second matching surface 32 of the second sealing strip 3 and contacts the bottom of the weir crest flow channel downward on the same horizontal plane; the bottom side surface of the first sealing strip 2 is closely abutted with a first vertical matching surface 31 on the second sealing strip 3, so that the first sealing strip 2 and the second sealing strip 3 continuously seal the weir crest flow channel; the sealing surface 21 of the first sealing strip 2, which is positioned outside the side edge of the door panel 1, is flush with the end surface of the second sealing strip 3 and is used for being in contact sealing with the side wall of the weir crest flow channel.
