In this embodiment, the position of the floating member is lower than the first liquid level a, that is, in the normal use process of the floor drain, the floating member is always immersed in the stored water rather than floating on the liquid level, the connecting member passes through the second liquid level B and the radial sealing plate 3, the driving member is located below the second liquid level and also located below the radial sealing plate 3, the radial sealing plate 3 traverses the bottom of the vertical extension cavity and the U-shaped cavity 1.1, the edge of the radial sealing plate is attached to the cavity wall of the vertical extension cavity or the U-shaped cavity 1.1, the power input end of the transmission assembly 5 is driven by the driving member, and the power output end drives the radial sealing plate 3.

In the floor drain with the water seal combined automatic mechanical seal provided by this embodiment, the movement direction of the float assembly 4 is a vertical direction, that is, along the axis direction of the vertical section, the movement direction of the radial sealing plate 3 is also a vertical direction, but the directions of the two specific movements are opposite, that is, when the float assembly 4 moves downwards, the radial sealing plate 3 moves upwards, and when the float assembly 4 moves upwards, the radial sealing plate 3 moves downwards, the movement power of the float assembly 4 comes from the buoyancy of the water in the U-shaped cavity 1.1 to the float member, the power of the radial sealing plate 3 comes from the driving of the float assembly 4 through the transmission assembly 5, in this embodiment, the transmission assembly 5 is a reverse transmission mechanism, that is, the forward movement of the float assembly 4 can drive the radial sealing plate 3 to move reversely through the transmission assembly 5, which is the simplest and most effective, as shown in fig. 5-6, the gear transmission structure is characterized in that a first rack is arranged on the floater component 4, a second rack is connected to the radial sealing plate 3, the first rack and the second rack are respectively meshed with two opposite sides of a gear, so that the movement of the first rack can bring the reverse movement of the second rack, and the transmission ratio can be controlled by adjusting the number of the gears, so that the control of the ratio of the movement strokes of the floater component 4 and the radial sealing plate 3 is realized.

When the U-shaped cavity 1.1 is not used for a long time, the water stored in the U-shaped cavity 1.1 begins to evaporate and descend, in the process that the stored water is lowered from the first liquid level A to the second liquid level B, the floating ball 4.1 integrally moves down under the action of gravity because of losing buoyancy, the downward movement drives the transmission component 5 to drive the radial sealing plate 3 to move upward, before the transmission of the transmission component 5, such as a gear, is configured to reach the second liquid level B, the radial sealing plate 3 moves upward to the position of the second liquid level B, that is, abuts against the low point of the pipe body 1 at the concave part of the U-shaped cavity 1.1 and the top cavity wall at the bent part of the U-shaped cavity 1.1, at this time, the radial sealing plate 3 blocks the two vertical cavities of the U-shaped cavity 1.1, when the stored water continues to descend to the second liquid level B, due to the blockage of the radial sealing plate 3, the evaporation rate of subsequent water storage is greatly reduced, and the drying rate is greatly reduced. Moreover, even if the water stored in the U-shaped cavity 1.1 and the vertically extending cavity 2 is completely dried after a long time, such as several months and a year, the back-filling amount of the odor in the sewer can be reduced due to the blockage of the radial sealing plate 3, and simultaneously, the rat and insect in the sewer can be prevented from entering the building through the sewer pipe. When the radial sealing cavity reaches the second liquid level B and is sealed, someone uses the drainage system again, new flowing water is flushed into the U-shaped cavity, the radial sealing cavity can be pressed down under the dual actions of the pressure of the flowing water and the buoyancy of the floater component 4 to return to the initial position, the U-shaped cavity can be normally used, and the ascending and descending circulation of the radial sealing cavity is completed.
