[0042] The automatic linkage system 6 comprises a first linkage 28, the top end of the first linkage 28 is provided with a warning block 27, the bottom is hingedly connected with one end of a second linkage 29 and one end of a fourth linkage 31 through a first rotating knob 35, a fifth linkage 34 is connected in a long hole at the other end of the second linkage 29 through the first rotating knob 35, the fifth linkage 34 can slide in the long hole of the second linkage 29, a first fixed linkage 32 is rotatably connected on the fourth linkage 31, the long hole at the other end of the fourth linkage 31 is connected with one end of a third linkage 30 through the first rotating knob 35, and the third linkage 30 can slide along the long hole on the fourth linkage 31, a second fixed linkage 33 which is the same as the first fixed linkage 32 in direction is rotatably connected on the third linkage 30, the end of the first fixed linkage 32 and the second fixed linkage 33 are both welded on the inner side wall of the well wall 5, and a stainless steel floating ball 36 is installed at the other end of the third linkage 30 through the first rotating knob 35. The automatic linkage system is made of aluminum alloy material and is subjected to oxidation treatment, which improves the corrosion resistance of the linkage and prevents the linkage from working difficultly due to serious corrosion in water. The stainless steel floating ball 36 can effectively float up and down by using the common stainless steel floating ball valve in the market. When the water level of the one-layer water containing device 4 rises due to too much garbage in the well, the stainless steel floating ball 36 pulls the linkage, the warning block 27 is floated up by the linkage and warns the sanitation worker to immediately deal with the garbage in the well.

[0043] The rotating water leakage outlet 7 comprises a rotating base plate 39 with a through hole in the center, a plurality of fixed bases 43 with a U-shaped cross section are installed on the through hole of the rotating base plate 39 in the circumferential direction, the fixed bases 43 are clamped on the rotating base plate 39 and surround the circular through hole, the upper surface and the lower surface of the fixed base 43 are welded with fixed rotating knobs 44, the rotating water leakage outlet 7 is fixed at the bottom of the water storage tank 22 through the fixed rotating knobs 44 at the lower part of the fixed base 43, which is used to block or open the water leakage outlet, the rotating base plate 39 is connected with one end of the rotating pull rod 41 through the second rotating knob 38, the upper surface of the rotating base plate 39 is provided with a limiting column 40 corresponding to each rotating pull rod 41, the other end of the rotating pull rod 41 is connected with the outer convex end of the petal-shaped rotating mouth 37 through the movable rotating knob 42, one end of the inner concave side of the petal-shaped rotating mouth 37 is rotatably installed on the fixed rotating knob 44 at the upper part of the fixed base 43, and the petal-shaped rotating mouth 37 can rotate around the fixed rotating knob 44. The rotating base plate 39 is inserted and fixed with the fifth connecting rod 34 of the automatic connecting rod system 6 through the through hole on the outer elongated rod. The rotating water leakage outlet 7 is made of aluminum alloy material and is subjected to oxidation treatment, so it has strong corrosion resistance and can prevent rust from causing the mechanism to fail to work.

[0044] When the stainless steel floating ball 36 moves up and down, the automatic connecting rod system is driven to work. When the stainless steel floating ball 36 moves upward under the action of the water buoyancy, one end of the third connecting rod 30 connected with the fourth connecting rod 31 moves downward, drives the fourth connecting rod 31 to rotate clockwise, and in turn drives the first connecting rod 28 to move upward, at the same time, the one end of the second connecting rod 29 connected with the first connecting rod 28 is pulled upward, thereby driving the fifth connecting rod 34 to move toward the first connecting rod 28, the movement of the fifth connecting rod 34 drives the rotating base plate 39 to rotate clockwise, the rotating base plate 39 drives the rotating pull rod 41 to rotate, and in turn drives the petal-shaped rotating mouth 37 to rotate around the fixed rotating knob 44 through the movable rotating knob 42 on one side of the petal-shaped rotating mouth 37. Under the action, the petal-shaped rotating mouth 37 is pulled to rotate around the fixed rotating knob 44 to open, and is stopped from rotating through the limiting column 40, so that the sewage in the water storage device 4 flows into the well wall 5 through the opened water outlet, avoiding the sewage overflow problem caused by the failure of the sanitation worker to timely treat the garbage in the well, and playing a buffering role of secondary drainage. At this time, the water level of the water storage device 4 drops to a certain position, the stainless steel floating ball 36 drives the connecting rod to move downward under the action of gravity, at this time, the rotating water leakage outlet 7 is rotated to close in the original way. When the water level in the well rises again, the above process is repeated, the warning block 27 repeatedly warns the sanitation worker to timely treat the garbage, effectively avoiding the sewage overflow problem.

[0045] The working principle of the floating force automatic drainage well device with multiple warning functions is as follows:

[0046] As Figure 11 and Figure 12When the water level in the first layer water container 4 continues to rise due to excessive garbage or clogged drainage, the stainless steel floating ball 36 pulls the third connecting rod 30 upwards to rotate the third connecting rod 30 counterclockwise, and the third connecting rod 30 drives the fourth connecting rod 31 to rotate clockwise, thereby pushing the first connecting rod 28 upwards. When the floating reaches a certain position, the warning block 27 is lifted to the horizontal position of the first layer filter device 1 through the action of the first connecting rod 28. The warning block 27 is designed in red to attract attention. When the sanitation worker sees the warning block 27 floating out, he needs to clean the garbage in the well. The sanitation worker removes the second layer filter device 3 with garbage through the lifting ring 19 and replaces the new second layer filter device 3, achieving the effect of efficient garbage disposal. If the sanitation worker does not timely discover and handle the garbage in the well, the water level in the first layer water container 4 will continue to rise, the stainless steel floating ball 36 pulls the third connecting rod 30 to continue floating, the third connecting rod 30 continues to rotate counterclockwise, the third connecting rod 30 drives the fourth connecting rod 31 to continue to rotate clockwise, and the first connecting rod 28 and the second connecting rod 29 are pulled upwards. At this time, the second connecting rod 29 and the fifth connecting rod 34 are pulled to move closer to the first connecting rod 28 under the action of the first connecting rod 28, the movement of the fifth connecting rod 34 drives the rotating water outlet 7 to rotate and open to the position of the limiting column 40, and the water in the first layer water container 4 flows into the box of the well wall 5 through the rotating water outlet 7. The water flows into the well wall 5 and is discharged through the lower drainage pipe 26, and the water level in the first layer water container 4 gradually decreases. The stainless steel floating ball 36 sinks to a certain position under the action of gravity, pulls the automatic connecting rod system to make the fifth connecting rod 34 return to the original position, and closes the rotating water outlet 7. Then when the water level in the first layer water container 4 rises again, the above process is repeated, which plays a role in warning the sanitation worker to timely handle the garbage in the well. This process repeatedly warns the sanitation worker through automatic design and two-layer water system to avoid the problem of sewage overflow due to the sanitation worker's failure to timely handle the garbage in the well. The well wall 5 device acts as a second layer water container and plays a buffering role, effectively preventing sewage overflow, achieving the effect of automatic design, improving garbage disposal efficiency, improving the working environment, effectively preventing well drainage blockage, and providing support for urban drainage system construction.
