Technical Field

The invention relates to the technical field of sponge cities, in particular to a drainage system for a sponge city roof garden.

Background

The sponge city is a new generation of city rainfall flood management concept, and refers to a city which can be like a sponge and has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and the city can also be called as a water elasticity city.

The roof garden can play a good role in water storage and a good rainwater utilization effect, and is widely applied to construction of sponge cities, but the existing roof garden is easy to cause water outlet blockage due to accumulation of sundries such as fallen leaves and the like, so that a large amount of accumulated water is generated in the continuous rainfall process, and the roof garden is damaged due to excessive accumulated water.

Disclosure of Invention

The invention aims to solve the problem that a roof garden in the prior art is difficult to drain, and provides a drainage system for the roof garden of a sponge city.

In order to achieve the purpose, the invention adopts the following technical scheme: a drainage system for sponge city roof gardens comprises a water leakage box, wherein a plurality of water leakage grooves are formed in the bottom of the water leakage box, a partition plate is fixed to the inner bottom of the water leakage box, a power cavity is formed in the partition plate, the upper end of the power cavity is connected with a rotating shaft in a penetrating and rotating mode, a scraper is welded at the upper end of the rotating shaft, a filter plate is fixed to the side wall of the upper end of the water leakage box, rotating blades are fixed to the circumferential side wall of the rotating shaft and abut against the upper end of the partition plate, a power device for removing deposits is arranged in the power cavity, an inflation cavity is formed in the partition plate, an inflation hole communicated with the power cavity is formed in the side wall of the inflation cavity, an air inlet hole is formed in one side, away from the inflation cavity, of the power cavity, one-way valves are arranged on the inner walls of the inflation hole and the air inlet hole, an exhaust hole communicated with, the baffle is kept away from one side in power chamber and is seted up the spout with aerifing the chamber intercommunication, the inside of spout is equipped with the device that bears that is used for cleaing away the deposit, the outer wall of box that leaks is fixed with the receiver, the inside workbin of getting that is equipped with of receiver, the row's silo that communicates with the receiver is seted up to the lateral wall of box that leaks.

In the drainage system for the sponge city roof garden, the power device comprises a support rod fixed at the bottom in the power cavity, the upper end of the support rod is rotatably connected with a lead screw, the upper end of the lead screw is welded with the lower end of a rotating shaft, the circumferential side wall of the lead screw is rotatably connected with a slide block, the side wall of the support rod is sleeved with a propelling block, and the slide block and the propelling block are jointly connected with a connecting rod.

In foretell drainage system for sponge city roof garden, bear the device including the reset spring of welding at the spout bottom, reset spring's upper end welding has the push pedal with the inside sliding connection of spout, the push pedal is kept away from one side of baffle and is connected with the loading board through the torsional spring rotation, the lateral wall of loading board has seted up the turn trough, the inner wall of turn trough is connected with the rotor plate through the torsional spring rotation, the upper end of rotor plate support have with the box inner wall welded dog that leaks, the one end veneer that aerifys the chamber and communicate with the spout has the elasticity bag.

Compared with the prior art, the invention has the advantages that:

1. in the invention, the sundries are blocked by the filter plate, so that the water leakage box cannot be directly blocked by the sundries, the continuous and effective fluidity of the water leakage box is maintained, the drainage of the roof garden can be ensured to be normally carried out, the roof water flow retention caused by the blockage of the water leakage box is effectively avoided, and the roof garden can be effectively used in the rainfall process;

2. according to the invention, the rotating blade is driven to rotate by the impact of water flow, and the rotating shaft and the scraper are driven to rotate by the rotation of the rotating blade, so that sundries blocked by the filter plate are pushed by the scraper, further the sundries are not accumulated above the filter plate to cause the blockage of the filter plate, and further the water flow at the position of the filter plate can continuously circulate;

3. in the invention, the sundries are pushed to the other side of the partition plate by the scraper plate, so that the sundries are collected in a centralized manner and cannot fall above the water leakage box, the whole roof garden is cleaner and tidier, the sundries cannot fall randomly, meanwhile, the centralized collection of the sundries can facilitate subsequent centralized treatment, and the cleaning difficulty is reduced;

4. according to the invention, the screw rod rotates along with the rotation of the rotating shaft, so that the propelling block moves in a reciprocating manner, the continuous inflation of the inflation cavity is further completed, the elastic bag is expanded under stress to push the push plate to move, the bearing plate moves downwards to increase the overall storage space, and more sundries can be effectively stored in one-time rainfall process;

5. in the invention, the bearing plate deflects under the blocking action of the stop block in the process of moving upwards after rainfall stops, so that sundries accumulated on the bearing plate slide into the material taking box, the sundries can be conveniently and centrally treated subsequently, the upper part of the water leakage box is shielded by the bearing plate, and the situation that objects which fall carelessly directly enter the material taking box to cause difficulty in picking up and even damage is avoided.
