Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

An automatic drainage device for preventing waterlogging and ponding comprises a well cover 1 and a cylindrical shaft sleeve 2 which is vertically arranged, wherein four openings 21 which are vertically and uniformly arranged are respectively arranged on the upper end circumference and the lower end circumference of the shaft sleeve 2, two X-shaped movable supports 3 which are vertically arranged are arranged in the shaft sleeve 2, the movable supports 3 are vertically arranged, and the movable supports 3 comprise two movable support rods 31 which are crossly arranged; a connecting spring 32 is arranged between the upper movable supporting rods 31 of the upper movable bracket 3, and a connecting spring 32 is also arranged between the lower movable supporting rods 31 of the lower movable bracket 3; the crossing points of the movable support rods 3 are hinged and fixed in the shaft sleeve 2 through long bolts 33; the water bucket also comprises two connecting ropes 4 which are arranged at the bottom of the movable support 3 and connected with the movable support rods 31 in the same group, wherein hooks 41 are arranged at the cross points of the connecting ropes 4, and the hooks 41 are connected with a water bucket 5 with water leakage holes 51; well lid 1 includes that the lid sets up in the bellied lantern ring 11 of lid lower surface lantern ring 11 lower surface is equipped with four square poles 12 that are the cross and arrange all be equipped with T shape spout 13 on four square poles 12, square pole 12 pass through slider 14 and T shape spout 13 with movable branch 31's upper end slidable connection.

During actual installation, the shaft sleeve 2 needs to be fixed inside the drainage well, and the tight fixed connection between the outside of the shaft sleeve 2 and the inner wall of the drainage well is ensured. When the water bucket 5 is empty, the connecting spring 32 is in a slightly compressed state under the action of the X-shaped movable support 3 and the self weight of the water bucket, the angle between the movable support rods 31 is larger, and the movable support rods 31 penetrate through the shaft sleeve 2 through the opening 21 arranged on the shaft sleeve 2 and are connected with the slide block 14 on the square rod 12; when rainfall begins, under the condition that the initial rainfall is small, rainwater falls into the bucket 5 at the bottom through the drain holes 15 vertically penetrating the well cover 1 and is drained out of the water leakage holes 51 in the bucket 5, at the moment, the drainage speed of the bucket 51 is far greater than the water inlet speed, so that the self weight of the bucket 5 cannot be changed greatly; when the precipitation is too large, rainwater falls into the bucket 5 through the vertically through drain holes 15 on the well lid 1, part of the rainwater is drained from the drain holes 51 in the bucket 5, and at the moment, the drainage speed of the bucket 51 is far less than the water inlet speed, so that the self weight of the bucket 5 is increased, the lower ends of the movable support rods 31 in the same group of movable supports 3 are driven to be folded, and the top ends of the movable support rods 31 are driven to be folded through the sliding blocks 14 and the T-shaped sliding grooves 13; because the movable support 3 is fixed in the shaft sleeve 2 by the long bolt 33, and the shaft sleeve 2 is fixedly connected with the side wall of the drainage well, when the top of the movable support rod 31 is folded, the slide block 14 slides towards the circle center in the T-shaped slide groove 13, so that the well cover 1 is jacked up, the drainage of rainwater from the drainage hole 15 is changed into drainage from a gap between the well cover 1 and the ground, the drainage quantity is increased, and meanwhile, the rainwater continuously falls into the water bucket 5 to keep the water bucket 5 in a full state; after the precipitation is reduced, because the water leakage hole 51 arranged in the bucket 5 continuously leaks water, the drainage speed of the bucket 51 is changed to be smaller than the water inlet speed again, at the moment, the self weight of the bucket 5 is reduced, the upper end and the lower end of the movable support 3 are separated under the action of the connecting spring 32, the movable support rod 31 falls into the corresponding opening 21 again, the bucket 5 is driven to ascend, the well cover 1 is slowly lowered and falls into the mounting hole of the well cover 1 again, and the whole working cycle is completed.

As a preferred embodiment, the projections of the long bolts 33 of the two movable brackets 3 on the horizontal plane are perpendicular to each other; because the whole movable support 3 is fixed in the shaft sleeve 2 only by the action of the long bolt 33, the acting force applied to the inside of the shaft sleeve 2 can be better balanced in a vertical state, and the side turning is prevented.

As a preferred embodiment, the manhole cover 1 is further provided with a plurality of drainage holes 15 which vertically penetrate through the manhole cover.

As a preferred embodiment, the upper surface of the well cover 1 is also provided with anti-skid patterns.

As a preferred embodiment, the connecting spring 32 is a compression spring; since the connecting spring 32 is in a compressed state throughout the working cycle, the connecting spring 32 is set as a compression spring, and a compression spring having a large elastic limit is selected, and its elastic coefficient is also required to be relatively large.
