In rainy days, the water level in the sewer rises, the rising water pushes the floating plate 606 to move towards the direction close to the mounting plate 1, so that the floating plate 606 pushes the convex plate 605 and the upper device to move towards the direction close to the mounting plate 1, the convex plate 605 pushes the movable rod 602 and the wedge-shaped plate 603 which are positioned below to move towards the direction close to the second movable clamping seat 404, the first compression spring 604 in a normal state is stretched, the wedge-shaped plate 603 pushes the second movable clamping seat 404 to move towards the direction away from the mounting plate 1, the second return spring 405 in a normal state is compressed, the second movable clamping seat 404 does not block the opening 3 of the U-shaped plate any more, the water outlet is increased, and the water displacement is increased along with the water displacement. When the water level in the sewer continues to rise, the rising water level continues to push the floating plate 606 to move towards the direction close to the mounting plate 1, so that the floating plate 606 pushes the convex plate 605 and the upper device to move towards the direction close to the mounting plate 1, the convex plate 605 pushes the movable rod 602 and the upper device located above the convex plate to move towards the direction close to the first movable clamping seat 402, the first compression spring 604 in the normal state is stretched, the wedge plate 603 pushes the first movable clamping seat 402 to move towards the direction away from the mounting plate 1, the first return spring 403 in the normal state is stretched, the first movable clamping seat 402 does not block the opening 3 of the U-shaped plate any more, the water outlet is increased to the maximum, and the water discharge is also increased to the maximum. The purpose of controlling the water discharge by adjusting the size of the water outlet in a stepped manner is realized by matching the first movable clamping seat 402 with the second movable clamping seat 404. When convex plate 605 promotes the movable rod 602 that is located supporting seat 601 top and the last device towards being close to first activity cassette 402 direction motion, set-square 704 on wedge 603 promotes guide arm 701 and isolation frame 702 towards being close to the motion of mounting panel 1 direction, and second compression spring 703 is stretched, and isolation frame 702 protrusion ground will keep apart the external silt of frame 702 and keep apart, prevents that rivers from driving in silt gets into the sewer, leads to the sewer to block up, causes later stage clearance inconvenient.
When the water level rises and sinks over the floating ball 804, the floating ball 804 pushes the slotted swing plate 803 to swing, by the action of the first and second limiting plates 805 and 806, the slotted oscillating plate 803 is oscillated upward toward the fixed rod 5, the slotted oscillating plate 803 pushes the sliding rod 807 and the upper device thereof to move toward the fixed rod 5, the fourth compression spring 8011 is compressed, when the convex panel 605 drives the slotted plate 607 to move upward to a suitable height, the clamping plate 8010 is just clamped into the clamping groove of the slotted plate 607, so that when the water level is lowered at the later stage, through the cooperation of the clamping plate 8010 and the devices thereon, the floating plate 606 and the devices thereon cannot fall away from the mounting plate 1 immediately, the first movable clamping seat 402 and the second movable clamping seat 404 continue to maintain the current situation and cannot immediately block the two thirds of the position of the opening 3 of the return plate, the water outlet is still at the maximum position, and water flow can still be quickly discharged into a sewer. When the water level in the tunnel continuously drops below the floating ball 804, after the floating ball 804 loses buoyancy, the grooved swinging plate 803 is driven to reset under the action of gravity, the compressed fourth compression spring 8011 resets to drive the sliding rod 807 and the device thereon to move in the direction away from the grooved plate 607, the clamping plate 8010 no longer clamps the grooved plate 607, the grooved plate 607 and the device thereon move in the direction away from the mounting plate 1 under the influence of gravity, the stretched first compression spring 604 drives the movable rod 602 and the wedge-shaped plate 603 to reset in the direction close to the fixing rod 5, and the first reset spring 403 and the compressed second reset spring 405 reset to drive the first movable clamping seat 402 and the second movable clamping seat 404 to reset in the direction close to the mounting plate 1, and the first movable clamping seat 402 and the second movable clamping seat 404 block two thirds of the opening of the return plate 3. Meanwhile, the wedge plate 603 drives the triangle plate 704 to move towards the direction close to the fixing rod 5, so that the guide rod 701 loses thrust, the isolation frame 702 is driven to reset through the reset of the stretched second compression spring 703, the isolation frame 702 does not protrude out of the ground any more, and sanitation workers clean up residual silt on the ground after rainwater moves away.
