Rotation; the rotation of the well cover 2 will drive the third gear 42 meshed with it to rotate; the rotation of the third gear 42 will drive the fourth gear 45 to rotate; the rotation of the tenth gear will make the warning rod 39 move upwards, and finally move out of the upper side of the well cover 2; The function of the support spring 28 in the present invention is to support the hemispherical water filtering structure 5 by the support spring 28 in the initial state; The filter water holes 21 on the upper end surface are staggered, and its function is to filter the water flowing into the inner side of the well cover 2 through the first square water outlet 19 on the upper end surface of the well cover 2 and the filter water hole 21 on the upper end surface of the filter disc 13 ; Among the present invention, the end that cooperates with the square limit hole 52 on the third support rod 22, the limit port 16 on the well cover 2 and the limit hole 18 on the well cover installation shell 1 on the rack 8 has a 45-degree slope; The effect is that when the sundries on the well cover 2 are cleaned and put back to the original position, the rack 8 has a 45-degree slope to make the rack 8 return to the original position more easily; in the present invention, the hemispherical water filtering structure When the weight of the water stored in 5 is less than the weight of the water stored in the annular water filtering structure 6, the annular water filtering structure 6 will move downward; the downward movement of the annular water filtering structure 6 will drive the three first support rods 7 Move down; Three first support rods 7 move down and will make three telescopic rods 36 swing; Three telescopic rods 36 swings and will make three second gears 35 rotate; Three second gears 35 rotate and drive three Three first gears 33 rotate; three first gears 33 rotate to drive three racks 8 to move toward the central axis side away from well cover 2; that is, the extrusion between three racks 8 and three limit holes 18 Force increases; That is to say, three tooth bars 8 are more difficult to break away from the square limit hole 52 on the third support bar 22, the limit hole 16 on the well cover 2 and the limit hole 18 on the well cover installation shell 1; The spacing of the third support rod 22, the well cover 2 and the well cover installation shell 1 is more stable by the rack 8.

Specific embodiments: when people use the drainage equipment designed by the present invention, during normal use, if there is water accumulation around the well cover 2 in a rainy day, the water around the well cover 2 will pass through the first side of the well cover 2 Shaped water inlet 19 flows into the filter disc 13; then flows into the hemispherical water filter structure 5 and the annular water filter structure 6 through the filter water hole 21 on the filter disc 13; The manhole cover 2 on the upper side of the water filter structure 6 and the first square water outlet 19 and the filter water hole 21 on the filter disc 13 are not blocked; The amount of water on the water structure 5 is large; that is, the gravity of the water on the annular water filtering structure 6 is greater than the gravity of the water on the hemispherical water filtering structure 5; that is, the annular water filtering structure 6 will move downward at this time; the annular water filtering structure 6 Moving down will drive the three first support rods 7 to move downward; the downward movement of the three first support rods 7 will make the three telescopic rods 36 swing; the swing of the three telescopic rods 36 will make the three second gears 35 rotates; three second gears 35 rotate to drive three first gears 33 to rotate; three first gears 33 rotate to drive three racks 8 to move toward the central axis side away from well cover 2; that is, three racks 8 The squeeze force between the three limit holes 18 is increased; that is, the three racks 8 are more difficult to break away from the square limit hole 52 on the third support rod 22, the limit port 16 on the well cover 2 and the well cover The limit hole 18 on the installation shell 1 makes the three racks 8 more stable in limiting the third support rod 22 , the well cover 2 and the well cover installation shell 1 . The water flowing into the hemispherical water filtering structure 5 and the annular water filtering structure 6 will move to the lower side of the well cover 2 through the second water filtering hole 31 and the first water filtering hole 27; the water flowing into the lower side of the well cover 2 then passes through the well cover 2 The water outlet hole 20 on the outer surface and the water outlet 15 on the well cover installation shell 1 flow into the sewer 4 opened on the civil construction 3; When waiting for debris, these branches and leaves will be impacted by water to the vicinity of the well cover 2 after long-term use; The amount of water on the structure 6 is less than the amount of water flowing into the hemispherical water filtering structure 5; at this time, the hemispherical water filtering structure 5 will move downward, and the downward movement of the hemispherical water filtering structure 5 will drive the second support rod 9 Move down; the second support rod 9 moves downwards to drive the drive disc 10 to move downward; the drive disc 10 moves downward to drive the three second connecting lugs 37 to move downward; the three second connecting lugs 37 to move downward; Moving down drives three connecting telescopic rods 38 to move downwards; Because the second pin shaft 34 cooperates with the pin hole connecting one end of the telescopic rod 38 on the second pin shaft 34 and the telescopic rod 38; 38 and the second connecting lug 37 have formed a lever; due to the principle of leverage, so when the three connecting telescopic rods 38 move down, the three connecting telescopic rods 38 will make the three telescopic rods 36 connected thereto swing; The downward movement of a connecting telescopic rod 38 will make the three telescopic rods 36 connected to it move upwards with the end connected to the first connecting lug 26; It will make the corresponding three first support rods 7 move upwards; when the three telescopic rods 36 swing, the three telescopic rods 36 will drive the rotation of the three second gears 35; the rotation of the three second gears 35 will drive the three The first gear 33 rotates; the rotation of the three first gears 33 drives the three racks 8 to move towards the central axis side of the well cover 2; 1. When the limit port 16 on the well cover 2 and the limit hole 18 on the well cover installation shell 1 are separated; under the action of the compression spring 11, the well cover 2 will move upward; Tree branches and leaves and other sundries move to the upper side together; three guide blocks 51 will move upwards relative to the well cover 2 under the action of three tension springs 50 simultaneously; three guide blocks 51 move upwards to drive The three third support rods 22 move upward; the three third support rods 22 move upward to drive the filter disc 13 to move upward; the filter disc 13 moves upward to drive the clamp rod 49 installed on the filter disc 13 to move upward, and finally out of the upper surface of the well cover 2; moving to the clamping rod 49 on the upper side of the well cover 2 will block the branches and leaves and other sundries on the upper side of the well cover 2, preventing the branches and leaves from sliding down to the lower side of the well cover 2. The lower side is blocked; it affects the removal of water; since the well cover 2 is installed on the inside of the well cover installation shell 1 through threaded fit, the When the well cover 2 moves upward, the well cover 2 will rotate around its central axis; the rotation of the well cover 2 will drive the third gear 42 meshed with it to rotate; the rotation of the third gear 42 will drive the fourth gear 45 to rotate; the rotation of the tenth gear will Make warning bar 39 move upwards, move out of well cover 2 upper side at last; Because warning bar 39 upper side has warning fluorescent strip; Warning fluorescent bar on warning bar 39 will emit flashing to remind the traveler around well cover 2 at night; Prevent accidents. When the staff found that the well cover 2 moved out of the ground, the staff cleaned up the branches and leaves and other sundries on the well cover 2 upper side, and then the well cover 2 was pressed into the well cover installation shell 1 by auxiliary tools for reuse.
