One embodiment of the invention is as follows:
In the normal drainage stage, rainwater enters the sedimentation tank 3 after passing through the structures such as the first tank plate and the like, and enters the flushing tank 2 after sedimentation through the filtering holes 5. The traction ropes 62 are in a relaxed state at this time, the cover plate 7 closes the inlet of the drain pipe 8.
The self-flushing stage comprises the steps that when the liquid level rises, buoyancy force borne by the floating body 61 is increased and moves upwards along the sliding rail 63, the floating body 61 pulls the cover plate 7 through the traction rope 62 to enable the cover plate 7 to turn upwards and open the inlet of the drain pipe 8, at the moment, sludge and sundries in the drain pipe 8 are flushed by utilizing potential energy of water flow, the lower limiter 65 moves towards the sliding rail 63 along the track 68 under the impact of the water flow to exert a limiting function, when the liquid level drops, the floating body 61 moves downwards along the sliding rail 63 under the action of the lower limiter 65, the floating body 61 stops moving downwards, traction on the cover plate 7 is kept, the lower limiter 65 retracts along the track 68 under the action of the spring 66 after water discharge is finished, the limiting function is lost, the floating body 61 continues to move downwards, the traction rope 62 loses traction of the floating body 61, and the inlet of the drain pipe 8 is gradually closed under the action of self gravity of the cover plate 7.
As shown in fig. 3, in the intelligent monitoring and early warning stage, the liquid level sensor 11, the water quality sensor 12 and the pressure sensor 10 monitor the data of the tank body 1 in real time, and the data acquisition and transmission module transmits the data to the remote control end 13. The data analysis and early warning module of the remote control end 13 analyzes the received data, keeps monitoring when the received data is normal, sends out early warning signals when the received data is abnormal, and can timely carry out alarm processing by operation and maintenance personnel through the remote monitoring module.
Wherein, specifically:
In the liquid level rising stage, when the liquid level in the flushing tank 2 rises, the buoyancy force exerted on the floating body 61 increases and moves upward along the slide rail 63. The floating body 61 pulls the cover plate 7 through the traction rope to enable the cover plate to turn upwards, and the inlet of the drain pipe 8 is opened.
The upper limit locking mechanism is that an upper limit stopper 64 is arranged on the top of the sliding rail 63, and the upper limit stopper 64 limits the upward movement of the floating body 61 when the floating body reaches the top, so as to keep the opening state of the cover plate 7.
Lower limit locking mechanism, the lower limiter 65 is connected with a spring 66 arranged on the partition wall 4, and an arc-shaped plate 67 is arranged on the lower limiter 65. The lower stopper 65 does not go over the slide rail 63 when not draining water, and has no positioning function. When the water is discharged, the arc-shaped plate 67 is subjected to the impact force of the water to counteract the tensile force of the spring 66, the lower limiter 65 is driven to move along the rail 68 towards the sliding rail 63, the limiting function is achieved, when the impact force of the water is eliminated after the water is discharged, the spring 66 is retracted to drive the limiter 65 to move towards the partition wall 4, and the lower limiting function is lost.
The liquid level lowering stage is that when the liquid level in the flushing tank 2 is lowered, the buoyancy force applied to the floating body 61 is reduced and the floating body moves downward along the slide rail 63. Due to the obstruction of the lower limit 65, the floating body 61 cannot move downwards continuously, and the traction on the cover plate 7 is maintained, so that the cover plate 7 cannot be closed, and the accumulated water is ensured to be discharged. When the drainage is finished, the lower limiter 65 loses the limiting function, the floating body 61 moves downwards continuously, the traction rope 62 becomes loose along with the descending of the floating body 61, and the cover plate 7 closes the inlet of the drainage pipe 8 under the action of self gravity.
Wherein the floating body 61 may be designed in a cylindrical shape or a spherical shape to ensure stable floating in water, and a material having a density less than that of water, such as polyethylene or polypropylene, may be selected to provide sufficient buoyancy. The sliding rail 63 may be designed to be vertical or inclined, or may be provided with a plurality of positioning points as required for controlling the movement position of the floating body 61.
Another embodiment of the invention is as follows, with locking means and release means being provided as required:
Locking means the locking means may be designed as a click mechanical lock or electromagnetic lock mounted on top of the slide rail 63. When the floating body 61 reaches the top, the locking means automatically locks the traction rope 62, keeping the cover plate 7 in an opened state.
The release means may be designed as a spring or electromagnetic release mechanism which automatically releases the pull cord 62 when the liquid level drops. The release means may be controlled by a level sensor 11, which level sensor 11 sends out a signal triggering the release means when the liquid level drops to a preset level.

(1) Initial state
The floating body 61 is positioned at the bottom of the sliding rail 63, the traction rope 62 is loosened, and the cover plate 7 closes the inlet of the drain pipe 8 under the action of self gravity.
(2) Liquid level rising stage
The liquid level sensor 11 monitors the change of the liquid level in the flushing tank 2 in real time. As the liquid level rises, the buoyancy experienced by the float 61 increases and moves up the slide 63.

When the floating body 61 reaches the upper stopper 64, the floating body 61 is stationary, and the cover 7 is kept in an opened state.
(3) Flushing process
The rainwater in the flushing tank 2 rapidly flows into the drain pipe 8 under the action of gravity, and the potential energy of water flow is utilized to flush sludge and sundries in the drain pipe 8. The liquid level sensor 11 continues to monitor the liquid level change, ensuring the smooth progress of the flushing process.
(4) Liquid level lowering stage
The liquid level sensor 11 detects a drop in the liquid level. When the liquid level drops to a preset level, the release device automatically releases the pull cord 62. The floating body 61 moves downwards along the sliding rail 63, the traction rope 62 is loosened, traction on the cover plate 7 is lost, and the cover plate 7 closes the inlet of the drain pipe 8 under the action of self gravity.
