Specifically, the outer side surface of the buoyancy seat 2 is attached to the inner wall of the floating cavity 12 so as to transversely separate the floating cavity 12; and the upper end surface of the buoyancy seat 2 and the inner wall of the floating cavity 12 form a gravity cavity 24 which can accumulate rainwater; the upper end of the floating cavity 12 is communicated with the water inlet cavity 11 through the upper through hole 16, the highest position of the buoyancy seat 2 is located below the lower through hole 17, and rainwater enters the gravity cavity 24 from the water inlet cavity 11 through the upper through hole 16. In one embodiment, the outer side surface of the floating plate 21 is attached to the inner wall of the floating cavity 12, the floating plate 21 transversely partitions the floating cavity 12, and the floating plate 21 is positioned above the lower through hole 17; the upper end of the floating cavity 12 is communicated with the water inlet cavity 11 through an upper through hole 16; the upper through hole 16 is positioned above the highest position of the floating plate 21 in the floating cavity 12, and a certain distance is reserved between the connecting plate 23 and the upper through hole 16, so that the inner wall of the floating cavity 12, the floating plate 21 and the connecting plate 23 form a gravity cavity 24 capable of accumulating rainwater, and the downward acting force of the buoyancy seat 2 is increased; the problem that the self weights of the buoyancy seat 2 and the identification column 3 are not enough to enable the identification column 3 to reset downwards when impurities are clamped between the identification column 3 and the telescopic opening 43 is solved.
For the description of the force when the identification column 3 moves up and down, the buoyancy value of the buoyancy cavity to the buoyancy seat 2 is a first value, the gravity value corresponding to the maximum rainwater capable of being accumulated in the gravity cavity 24 is a second value, the gravity values corresponding to the buoyancy seat 2 and the identification column 3 are third values, and the resistance value of the upward overturning deformation of the separation blade 32 relative to the expansion port 43 is a fourth value; and the sum of the second numerical value and the third numerical value is greater than the fourth numerical value, and the sum of the first numerical value and the fourth numerical value is greater than the sum of the second numerical value and the third numerical value.

After buoyancy seat 2 and 4 magnetism of apron are inhaled and are connected, the position of buoyancy seat 2 is stable, avoids buoyancy seat 2 to rock along with the fluctuation of water level to avoid sign post 3 to rock. In addition, because buoyancy seat 2 adopts light material, structural strength is limited, can set up second jump ring 121 on the upper portion of unsteady chamber 12 to the position of the highest position of restriction buoyancy seat 2, make the water level when undulant, upwards oppress second jump ring 121 in order to offset the thrust of water by buoyancy seat 2's kickboard 21, avoid buoyancy seat 2's connecting portion to strike apron 4, damage kickboard 21 and the junction of connecting portion.
The working principle is as follows:
when raining, the rainwater flows into the water inlet cavity 11 along the water inlet 41 on the cover plate 4 through the water inlet hole 15; water in the water inlet cavity 11 enters the floating cavity 12 through the lower through hole 17; along with the accumulation of rainwater at intake antrum 11 and unsteady chamber 12, the water level in intake antrum 11 and the unsteady chamber 12 risees gradually, and buoyancy seat 2 floats along with the water level in unsteady chamber 12 to drive sign post 3 upwards to stretch out for apron 4, play the effect of sign road lane.
After the buoyancy seat 2 floats to a certain height, the baffle 32 on the identification column 3 begins to be turned downwards and deformed due to the expansion port 43, so that the lower part of the identification column 3 can pass through the expansion port 43.
After the flap 32 passes through the throat 43 by being deformed, the flap 32 is deformed upward to be restored, and the flap 32 is made to act on the upper end surface of the lid plate 4 to cover the throat 43 from above downward with the flap 32.
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 applied to the buoyancy seat 2 is increased to a certain degree, the identification column 3 can retract downwards to a certain extent, and the separation blade 32 and the upper end face of the cover plate 4 are further attached. And after the baffle plate 32 is further attached to the cover plate 4, the resistance to deformation of the baffle plate 32 is gradually increased until the sum of the deformation resistance and the buoyancy is equal to the gravity generated by the gravity cavity 24, so as to ensure the state that the baffle plate 32 is attached to the cover plate 4.
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; the upward supporting force of the water on the buoyancy seat 2 is reduced due to the water level of the floating cavity 12 falling, and the acting force of the gravity cavity 24 on the buoyancy seat 2 is unchanged at the moment, so that the baffle plate 32 is enabled to be overturned upwards and deformed; when the water level is lowered to a position which is not in contact with the buoyancy seat 2 completely, the baffle plates 32 can complete the action of turning upwards and deforming, so that the resistance of the baffle plates 32 clamped at the cover plate 4 is lost for the identification column 3, and the identification column 3 falls down to the water surface of the floating cavity 12 along with the buoyancy seat 2; 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.
The technical effects are as follows:
