A blocking platform 14 is horizontally arranged at a position above the diversion pipeline 5 in the well body 1, and the shape of the blocking platform 14 is matched with that of the well body 1. The vertical side walls of the retaining platforms 14 are fixedly connected with the well body 1. A flow hole 141 vertically penetrating the baffle table 14 is formed in the middle of the baffle table 14. A guide column 7 is vertically arranged between the circulation hole 141 and the bottom surface of the well body 1. The bottom end of the guide post 7 is fixedly connected with the well body 1, and the top end is exposed out of the through hole 141. The guide post 7 is sleeved with a spherical buoyancy block 71 at a position below the flow hole 141. The buoyancy block 71 is connected with the guide post 7 in a sliding mode. The cross-sectional area of the buoyancy block 71 is larger than the cross-sectional area of the flow hole 141 so that the buoyancy block 71 cannot pass through the flow hole 141 to reach the upper portion of the abutment 14.

A horizontal drainage pipeline 4 is arranged on the side wall of the well body 1 opposite to the side wall provided with the diversion pipeline 5, and the drainage pipeline 4 is communicated with the inside of the well body 1. The communication opening of the drainage pipeline 4 and the well body 1 is positioned between the top end of the well body 1 and the baffle platform 14.

Referring to fig. 2 and 3, the top end of the well body 1 is opened, the opening is provided with a square hollow well lid 2, and the well lid 2 is fixed on the top end of the well body 1 by a first fixing bolt 21.

When raining, rainwater enters from the well lid 2 and then reaches the bottom end of the well body 1 through the flow hole 141, and then flows into the reservoir 51 through the diversion pipeline 5. When the water in the reservoir 51 is gradually increased, the rainwater does not flow to the reservoir 51, but gradually gathers at the bottom of the well body 1, and the water level gradually rises. The buoyancy block 71 sleeved on the guide post 7 rises under the action of buoyancy, and finally the flow hole 141 is blocked by the buoyancy block 71, and the rainwater on the flow hole is gathered above the blocking platform 14. When the water surface of the rainwater reaches the drainage pipeline 4, the rainwater is discharged from the drainage pipeline 4.

Referring to fig. 3 and 4, the flow holes 141 are truncated cone-shaped with a small top and a large bottom, so that the buoyancy block 71 has higher blocking strength for the flow holes 141.

The side wall of the top of the well body 1 is provided with a limiting part 13 extending towards the inside of the well body 1, and the middle part of the limiting part 13 is provided with a through hole communicating the lower part and the upper part of the well body 1. A water baffle 6 which is horizontally arranged is arranged below the limiting part 13, and one end of the water baffle 6 is hinged with the well body 1 through a rotating shaft 61. The top surface of the water baffle 6 is tightly attached to the bottom surface of the limiting part 13. A plurality of floating blocks 62 at intervals are fixedly arranged on the bottom surface of the water baffle 6.

The lateral wall of the top of the well body 1 is horizontally provided with grooves which are arranged at intervals up and down and are arranged around the well body 1, the bottom of the groove at the upper part forms an installation platform 11, and the bottom of the groove at the lower part forms a suspension platform 12. The shape of well lid 2 matches with the shape of mount table 11, and well lid 1 is placed in mount table 11. The hanging table 12 is provided with a hanging basket 3 which is hollow and shaped like an inverted quadrangular prism, and the hanging basket 3 is provided with a plurality of through holes and is open at the top end. The side wall at the top end of the hanging basket 3 is provided with a folded edge which extends outwards and is abutted against the hanging table 12. The cradle 3 is fixed to the hanging table 12 by the second fixing bolt 31, and the cradle 3 is stabilized. The hanging basket 3 can prevent sundries in the rainwater from falling into the well body 1 and has a falling prevention function.

Referring to fig. 5, the bottom surface of the slider 62 on the bottom surface of the splash guard 6 is disposed obliquely, and the distance between the bottom surface of the slider 62 and the bottom surface of the splash guard 6 gradually increases as the distance of the slider 62 from the rotation shaft 61 increases.

The implementation principle of the embodiment is as follows: at the initial stage of precipitation or when the precipitation amount is small, rainwater entering the well body 1 from a well head firstly passes through the flow hole 141 to reach the well bottom under the action of gravity and enters the reservoir 51 through the diversion pipeline 5; as the water quantity in the reservoir 51 increases, water gradually gathers at the bottom of the well and rises, and the flow hole 141 is blocked by the buoyancy block 71. Rainwater cannot flow downwards any more, and is collected on the retaining platform 14 and flows out through the diversion drainage pipeline 4; when the drainage pipeline 4 flows backward, the water baffle 6 is jacked up to seal the well mouth, so that water cannot flow to the road surface through the well mouth, and the backflow preventing effect is achieved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
