Referring to fig. 1, a plurality of permeation tubes 4 penetrate through the bottom of a reservoir 3, the permeation tubes 4 are distributed on the side wall and the bottom wall of the bottom of the reservoir 3, capillary holes 41 are uniformly formed in the tube wall of each permeation tube 4, the capillary holes 41 are communicated with the inside of each permeation tube 4, so that collected rainwater can uniformly permeate into soil at the bottom of a city through the capillary holes 41, the water storage capacity of the city is improved, and the rainwater can be converted into underground water after being purified by the soil, so that the water resource can be reused.

Referring to fig. 1, a filtering screen 31 is fixed to the middle of the water reservoir 3 by bolts, and support frames are provided around and in the middle of the filtering screen 31 to divide the filtering screen 31 into a plurality of filtering units and to secure the strength of the filtering screen 31. The filtering gauze 31 is arranged at an angle of 30 degrees downwards relative to the horizontal plane, and the mesh number of the filtering gauze 31 is 10 meshes, so that the rainwater is pre-filtered.

Referring to fig. 1, the top of the filtering gauze 31 is filled with a fine sand layer 311, the fine sand layer 311 is yellow sand with a particle size of more than 2mm, and the fine sand layer 311 is uniformly laid on the top of the filtering gauze 31; the gravel layer 312 is uniformly laid on the top of the fine sand layer 311, and the gravel layer 312 is composed of gravel with the particle size larger than that of yellow sand, so that rainwater is filtered in advance, and the filtering effect of the filtering gauze 31 is prevented from being influenced by massive garbage or impurities.

Referring to fig. 1, an overflow pipe 32 is arranged at the top of the reservoir 3 in a communicating manner, the overflow pipe 32 is embedded in the ground, one end of the overflow pipe 32 far away from the reservoir 3 is communicated with a storage river 33, and the storage river 33 surrounds the city for a circle and therefore has enough water storage capacity, so that rainwater which is not filtered in time can be collected into the storage river 33 when the rainfall is large.

Referring to fig. 1 and 2, one end of the overflow pipe 32 close to the water storage river 33 is connected with a filter screen 321 through rotation of a rotating shaft, the top of the filter screen 321 is connected to the top of the overflow pipe 32 in a rotating manner, the filter screen 321 is in clearance fit with the overflow pipe 32, and the inner side wall of the overflow pipe 32 is integrally formed with a limiting flange which can be abutted to the filter screen 321, so that rainwater overflowing into the water storage river 33 is filtered.

Referring to fig. 2, the overflow pipe 32 is far away from the one end interference fit ground that is connected with the rotation of filter screen 321 and is inserted and be equipped with the locking pole 322, and the locking pole 322 has three along the even array of overflow pipe 32 circumference, and the locking pole 322 is inserted and is established the one side that is kept away from the spacing flange of filter screen 321, and filter screen 321 offsets with locking pole 322 to filter screen 321 fixes.

Referring to fig. 3, the top of the inspection well 2 is covered with an inspection well cover 21, the inspection well 2 is integrally formed with a stepped groove 22 at the bottom of the inspection well cover 21, an anti-falling net 221 is placed in the stepped groove 22, the anti-falling net 221 is formed by welding mutually perpendicular iron bars, and the anti-falling net 221 abuts against the bottom wall of the stepped groove 22, so that people are prevented from falling into the inspection well 2.

Referring to fig. 3, the side wall of the stepped groove 22 is located at the top of the anti-falling net 221 and is connected with two abutting rods 222 in a sliding manner, and the two abutting rods 222 are evenly arranged around the stepped groove 22. The top of the abutting rod 222 is integrally formed with an inclined guide surface 2221. A return spring 2222 for ejecting the abutting rod 222 is fixedly bonded to one end of the abutting rod 222 away from the falling prevention net 221, and an anti-falling member 2223 for preventing falling off is integrally formed at one end of the abutting rod 222 close to the return spring 2222, so that the falling prevention net 221 can be fixed to the bottom wall of the stepped groove 22.

The working principle is as follows:

in the process of urban rainfall, rainwater is collected into the water storage tank 3 through the inspection well 2, and the anti-falling net 221 of the inspection well 2 can filter the rainwater in advance and then fall into the water storage tank 3. The gravel layer 312 on the filtering gauze 31 in the middle of the water reservoir 3 filters large impurities again, the fine sand layer 311 can filter small impurities, and the filtering gauze 31 is used for final filtering after the filtering is finished. Filtered rainwater falls to the bottom of the reservoir 3, permeates into deep soil at the bottom of the city through capillary holes 41 on the permeation tube 4, and is purified by the soil to become a part of urban groundwater, so that the water storage capacity of the city is improved, the effect of a sponge city is achieved, and water resources are saved.

When the rainfall was too big, the rainwater that falls on rubble layer 312 did not have time to filter and can store from overflow pipe 32 overflow to retaining river 33, because retaining river 33 encircles city a week, the rainwater that its can save is more, can play the effect of adjusting the weather on the one hand, and on the other hand can save the rainwater to take when the water resource is deficient.

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.
