By adopting the technical scheme, the drainage cover is circumferentially rotated by the groove limiting cross rod, so that the drainage cover is required to be lifted earlier before rotation to cancel the matching of the cross rod and the groove, the possibility that the drainage cover moves downwards to the inside of the drainage well due to other factors when flood does not occur is reduced, and the possibility that the drainage cover moves downwards to influence the life of people due to the fact that the drainage cover rotates unexpectedly is reduced. The third chute is convenient for the installation and the disassembly of the drainage cover.

Optionally, the end part side wall of the end part of the drainage well far away from one end of the drainage cover is provided with a through hole.

Through adopting above-mentioned technical scheme, the rainwater that gets into in the drain well can be followed through-hole department and discharged, can not influence the normal inflow of drain well, and the rivers that flow through from the through-hole are to next structure.

Optionally, one end of the through hole, which is far away from the drainage well, is communicated with a rainwater well, and a filter screen is arranged below the through hole in the rainwater well.

Through adopting above-mentioned technical scheme, the rainwater from through-hole flow direction rainwater well filters debris such as middle stone, leaf and earth through the filter screen.

Optionally, catch basin bottom is equipped with filters well seat, filter well seat including rubble layer, gravel layer and the filter cloth that from top to bottom sets gradually.

By adopting the technical scheme, water flowing into the rainwater well from the through hole passes through the filter screen in the rainwater well, and then the gravel layer, the gravel layer and the filter cloth further filter the rainwater to obtain relatively clean water.

Optionally, the lateral wall of the rainwater well that the filter cloth is relative has seted up the apopore, apopore intercommunication filter equipment, filter equipment intercommunication cistern.

Through adopting above-mentioned technical scheme, water after through filtering the well seat flows to filter equipment from the apopore, carries out complete filtration to water and purifies to the clean rivers that obtain flow to the cistern, save in the cistern.

In summary, the present application includes at least one of the following beneficial technical effects:

1. when the rainfall is large and the displacement of the drainage well needs to be increased, the drainage cover can be moved downwards into the drainage well by rotating the drainage cover, so that the displacement of the drainage well is increased;

2. the arrangement of the annular guide surface enables rainwater on the ground to move towards the drainage cover;

3. the recess makes the horizontal pole can not remove on first spout because of other factors to the spacing of horizontal pole, and then can not make the drainage lid when not taking place the flood condition, moves down inside the drainage well.
