The lower end surface of the floating sleeve 31 is in contact with the upper end surface of the rotating sleeve 41, the outer diameter of the floating sleeve 31 is larger than that of the rotating sleeve 41, each spiral deflector 311 is positioned between two rotating side plates 412, and the upper end of the rotating side plate 412 positioned at the counterclockwise direction side of the spiral guide plate 311 is positioned in the groove of the spiral guide plate 311, the lower end of the spiral guide plate 311 is inserted into the water seal groove between the two rotating side plates 412, a gap is arranged between the lower end of the spiral guide plate 311 and the upper surface of the water seal bottom plate 411, a gap is arranged between the lower spiral surface of the spiral guide plate 311 and the overflow plate 413, so that the floating sleeve 31 rises under the action of water and drives the spiral guide plate 311 to rise, the upper end of the rotating side plate 412 is withdrawn from the groove, so that the water flowing along the spiral guide plate 311 impacts the corresponding rotating side plate 412 to rotate the rotating side plate 412, so that the spiral guide plate 311 continues to move upwards at least under the push of the rotating side plate 412.
The arc wedges 414 are fixedly connected to the inner circumferential surface of the rotating sleeve 41 through the sliding blocks 417, the arc wedges 414 are uniformly distributed along the circumferential direction of the rotating sleeve 41, the distance from the arc wedge surface of the arc wedges 414 to the center of the rotating sleeve 41 gradually decreases along the clockwise direction, the arc wedges 414 are positioned inside the downcomer 21, and the sliding blocks 417 are positioned in the guide holes 215, so that the arc wedges 414 are rotatably connected with the downcomer 21.
The inner ends of the turning plates 51 are hinged to the lower end of the sewer pipe 21 and are uniformly distributed along the circumferential direction of the sewer pipe 21, the turning plates 51 are located below the rotating sleeve 41, and the inner ends of the turning plates 51 are provided with extension columns 511 extending to the lower portion of the arc-shaped wedge blocks 414, so that when water flow impacts the turning plates 51, the turning plates 51 are turned over downwards, the inner ends of the extension columns 511 upwards press the lower edges of the arc-shaped wedge surfaces, the arc-shaped wedge blocks 414 are enabled to rotate clockwise, and the rotating sleeve 41 is driven to rotate.
In this embodiment, as shown in fig. 5, 6 and 7, when the floor drain is not in operation or a small water flow passes between the downcomer 21 and the outer floor drain cylinder 6, the water flow flows into the water seal groove through the spiral guide plate 311, and flows into the lower end of the outer floor drain cylinder 6 from the gap between the spiral guide plate 311 and the water seal bottom plate 411, across the upper end of the overflow plate 413, and the gap between the spiral guide plate 311 and the water seal bottom plate 411 forms a water seal to seal the floor drain, so as to isolate odor. At this time, the flap 51 assumes a downward inclined posture under the blockage of the arc-shaped wedge 414. The water in the water seal tank which has the sealing function is not sucked away by the indoor drain pipe due to the siphoning effect because of the functions of the water seal bottom plate 411, the overflow plate 413 and the rotating side plate 412, and the sealing reliability of the overflow structure is improved.
As shown in fig. 8 and 9, when a large amount of water flows between the downcomer 21 and the outer pipe of the floor drain, the overflow plate 413 does not drain water so much that the water flow is gathered between the spiral guide plate 311 and the rotating side plate 412, after the water flow is gathered to a certain degree, the acting force of the water on the lower surface of the floating sleeve 31 is increased, the floating sleeve 31 moves upwards along the downcomer 21 under the action of the water and drives the spiral guide plate 311 to move upwards, so that the upper end of the rotating side plate 412 is separated from the groove of the spiral guide plate 311, and then the floating sleeve 31 can continue to move upwards under the action of the water. Meanwhile, water flows along the spiral guide plate 311 to impact the rotating side plate 412, the rotating side plate 412 rotates along the sewer pipe 21 through the rotating sleeve 41 under the impact action of the water flows, the rotating side plate 412 rotates to further push the spiral guide plate 311 to move upwards, and a sewer opening on the lower side of the spiral guide plate 311 is increased to accelerate the drainage speed.
When the spiral guide plate 311 exits the water seal tank, the water flow flowing down through the spiral guide plate 311 impacts the turning plate 51, the turning plate 51 turns downward under the impact force of the water flow, so that the inner end of the extension column 511 is tilted upward to press the lower edge of the arc wedge surface, and the lower edge of the arc wedge surface is pressed to drive the arc wedge block 414 to rotate clockwise along the sewer pipe 21 through the matching of the slide block 417 and the guide hole 215, so as to drive the rotating sleeve 41 to rotate. The rotating sleeve 41 is rapidly rotated under the impact action of water flow and the pressing action of the turning plate 51 on the arc wedge block 414, so that the spiral guide plate 311 rapidly moves to the upper end limit position, the water outlet is increased to the maximum, and large-flow water flows away rapidly through the water outlet. After the water flow is reduced to a certain degree or the water is drained, the floating sleeve 31 drives the spiral guide plate 311 to descend, the spiral guide plate 311 descends to press the rotary side plate 412, the rotary side plate 412 rotates anticlockwise along the sewer pipe 21 through the rotary sleeve 41 to return to the original position, and meanwhile, the turning plate 51 returns to the original position under the pressing of the arc-shaped wedge blocks 414.
A plurality of water passing ports 212 are uniformly distributed at the lower part of the downcomer 21 along the circumferential direction thereof, the water passing ports 212 are positioned above the guide hole 215, and the water passing ports 212 are communicated with the inner space of the downcomer 21 so that the water passing ports 212 are opened after the floating sleeve 31 rises for a preset distance. After the water passing port 212 is opened, large-flow water flow can be discharged through the water passing port 212, so that the water passing port 212 does not occupy a drainage channel when large-flow water flow exists on the ground, the drainage speed is accelerated, and the situation that the water flow does not submerge the indoor ground in time is avoided.
The extension column 511 is vertically connected to the middle of the inner end face of the flap 51. In two adjacent overflow structures, a communication opening is formed between the overflow plate 413 of one overflow structure and the rotating side plate 412 of the other overflow structure, and each turning plate 51 is positioned at the lower side of one communication opening.

The inner end surface (i.e., the second vertical plane) of the flap 51 is a vertical surface, so that the flap 51 is prevented from interfering with the downcomer 21 when turned downward.
As shown in fig. 10 and 11, in the present embodiment, a large water flow passes through the interior of the downcomer 21, and water reversely flows due to the excessive water flow and is not discharged in time, the reverse-flowing water presses the turning plate 51 upwards, the turning plate 51 turns upwards, and the upper surface of the turning plate 51 contacts with the lower surfaces of the two adjacent water seal bottom plates 411 to seal the communication ports, so as to block the reverse-flowing water from flowing out of the floor drain, thereby playing a role of preventing water from flowing backwards and preventing the indoor space from being flooded. If slow water return occurs in the downcomer 21 or the downcomer 21 overflows upwards, the flap 51 will turn upwards under the buoyancy of water to block the communication opening.
