After the buoyancy seat 2 floats to a certain height, the first magnetic attraction piece 231 and the second magnetic attraction piece 42 start to generate magnetic attraction force, so that the buoyancy seat 2 can be driven to float actively, and finally the buoyancy seat 2 and the cover plate 4 are magnetically attracted and positioned.
After the buoyancy seat 2 is magnetically attracted and positioned, the water level of the water inlet cavity 11 continues to rise, so that rainwater can flow into the gravity cavity 24 constructed by the buoyancy seat 2 and the floating cavity 12 from the water inlet cavity 11 through the upper through hole 16, the downward acting force borne by the buoyancy seat 2 is increased to a certain degree, and the sum of the downward acting force borne by the buoyancy seat 2 is smaller than the sum of the upward acting force borne by the buoyancy seat 2 at the moment, so that the mark column 3 is kept extending out on the road.
After the rain stops, water in the water inlet cavity 11 and the floating cavity 12 is discharged outside through the water discharging hole 19 assembly, and the water levels in the water inlet cavity 11 and the floating cavity 12 are gradually reduced; because the water level of the floating cavity 12 is lowered, the upward supporting force of water on the buoyancy seat 2 is reduced until the sum of the downward acting force applied to the buoyancy seat 2 is greater than the sum of the upward acting force applied to the buoyancy seat 2, at the moment, the magnetic attraction state between the buoyancy seat 2 and the cover plate 4 is released, and the buoyancy seat 2 falls downwards onto the water surface of the floating cavity 12; thereafter, the buoyancy seat 2 moves downwards to drive the identification column 3 to retract downwards continuously.
The position of the buoyancy seat 2 is continuously lowered along with the water level descending until the position is descended to the communication between the gravity cavity 24 and the water outlet 18 on the wall of the floating cavity 12, the rainwater accumulated in the gravity cavity 24 is discharged from the water outlet 18, the downward action on the buoyancy seat 2 is reduced, and the buoyancy seat 2 can float upwards again when raining next time.
