The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

FIGS. 1-5 show: a community waterlogging prevention rapid coping system based on a tough city comprises a community building 1, a water tank 2, a water inlet control structure 4 and a filtering structure 5.

1 top setting of community's building is used for the water tank 2 of storing, sets up the multiunit on the water tank 2 and is used for controlling the inflow control structure 4 that the rainwater got into, sets up the filtration 5 that is used for filtering and water in the water tank 2.

The water tank 2 comprises a tank body 21, an upper partition plate 22, a lower partition plate 23 and water inlet holes 24, wherein the upper partition plate 22 and the lower partition plate 23 are sequentially arranged in the tank body 21 from top to bottom, an inner cavity of the tank body 21 is sequentially divided into an upper cavity, a middle cavity and a lower cavity from top to bottom, the water inlet holes 24 are uniformly formed in the upper partition plate 22, and a water inlet control structure 4 and a filtering structure 5 are correspondingly arranged in each water inlet hole 24.

The lowest part of the upper cavity is provided with a downcomer 10, the downcomer 10 is communicated with the lower cavity through a diversion pipe 9, a control valve 11 is arranged on the downcomer 10 below the diversion pipe 9, and the lowest part of the middle cavity supplies domestic water to residents on each layer through a water supply pipe 8.

When taking place flood disasters and raining, the rainwater that falls on last baffle 22 flows to community ground through downcomer 10, when the rainwater needs to be stored, close control valve 11, the rainwater is saved in downcomer 10, the rainwater of saving in downcomer 10 gets into the cavity down through honeycomb duct 9, control structure 4 triggers intaking under the effect of rainwater buoyancy, intake opening 24 is opened when control structure 4 is lifted, later the rainwater in the epicoele passes through intake opening 24 and flows into filtration 5 at first, the purification back through filtration 5 then stores in the cavity, the rainwater of storing in the cavity supplies water to each layer resident on high-rise through delivery pipe 8. And during initial rainfall, the rainwater of first 2-5 mm generally pollutes seriously, causes filtration 5 easily to filter the difficulty, consequently leads the rainwater of anterior segment to the intracavity down through honeycomb duct 9, realizes abandoning class of initial rainwater, improves the quality of the rainwater of collecting.

The highest point of lumen is provided with wet return 6, through wet return 6 and the 7 intercommunications of recovery tank on community ground, consequently under the prerequisite of guaranteeing resident domestic water, in passing through wet return 6 and storing into recovery tank 7 with unnecessary water, neither makes the waste of water, can also avoid the lumen internal water volume too much, leads to water tank 2 to load too greatly.

When water supply to the middle cavity is not needed, the control valve 11 is opened, rainwater in the upper cavity flows down through the lower water pipe 10, and rainwater in the lower cavity firstly flows into the lower water pipe 10 through the flow guide pipe 9 and finally flows down through the lower water pipe 10.

The water inlet control structure 4 comprises a link rod 41, a floating ball 42 and a baffle 43, wherein the lower end of the link rod 41 successively penetrates through the upper partition plate 22 and the lower partition plate 23 to extend into the lower cavity and is provided with the floating ball 42, the upper end of the link rod is provided with the baffle 43, and the baffle 43 covers the water inlet hole 24.

After rainwater enters the lower cavity through the flow guide pipe 9, the floating ball 42 is subjected to the buoyancy of the rainwater, and the baffle 43 covering the water inlet hole 24 is jacked up through the connecting rod 41, so that the rainwater can flow into the lower cavity from the water inlet hole 24.

Example 2

The present embodiment is different from embodiment 1 in that: the box 21 is internally provided with a bearing structure 3 for supporting the upper partition 22 and the lower partition 23, and the bearing structure 3 comprises a column 31, an upper bearing net 32, a lower bearing net 33 and a backing plate 34.

The upright column 31 is vertically arranged at the top of the community building 1, the upper bearing net 32 and the lower bearing net 33 are sequentially fixed on the upright column 31 from top to bottom, the upper partition plate 22 and the lower partition plate 23 are respectively arranged on the upper bearing net 32 and the lower bearing net 33, a base plate 34 is arranged between the bottom end of the upright column 31 and the community building 1 and used for dispersing pressure, and the pressure of the upright column 31 on the roof of the community building 1 is reduced. The upper bearing net 32 and the lower bearing net 33 are net structures made of staggered structural steel through welding.

The rainwater pressure in the upper chamber and the middle chamber is respectively loaded on the upper clapboard 22 and the lower clapboard 23, when the rainwater amount is too large, the pressure caused by the corresponding upper clapboard 22 and the lower clapboard 23 is also large, and the upper clapboard 22 and the lower clapboard 23 are easy to be disconnected from the connection part of the box body 21. And the upper and lower partitions 22 and 23 are also easily broken due to the large span of the upper and lower partitions 22 and 23. Therefore, the upper bearing net 32 and the lower bearing net 33 are respectively arranged on the lower surfaces of the upper partition 22 and the lower partition 23 to support and share pressure, the upper bearing net 32 and the lower bearing net 33 are supported by the upright columns 31, and the pressure of the upper bearing net 31 and the lower bearing net 33 on the roof of the community building 1 is shared by the upright columns 31.
