[0023] The sponge city water circulation system includes a sponge city infiltration and drainage structure, an emergency water trough 300, a transfer water trough 330 and a bottom water reservoir 400. The emergency water trough 300 is opened inside the ground layer 100 and is located on both sides of the bottom end of the outer wall of the infiltration and drainage water inlet cylinder 200. The transfer water trough 330 is opened below the bottom end of the emergency water trough 300. The bottom water reservoir 400 is opened below the bottom end of the transfer water trough 330. The inner wall of the emergency water trough 300 is separated by a partition with a purification water trough 310. A diverter plate 311 is fixed to the top of the inner wall of the purification water trough 310. The bottom end of the outer wall of the diverter plate 311 is fixedly connected to multiple drain ports. A sand and gravel filter layer 312 for purification is installed on the inner wall of the purification water trough 310 and below the diverter plate 311. The inner wall of the water trough 310 is provided with a microbial filter layer 313 for purification below the sand and gravel filter layer 312. The microbial filter layer 313 is provided above the first short pipe. The purpose of the purification water trough 310 is to purify the infiltrated rainwater under normal use, and the diverter plate 311 can spray the rainwater evenly on the sand and gravel filter layer 312. The sand and gravel filter layer 312 is specifically a filter plate for storing some sand or sand particles. Rainwater can seep downward through the sand and gravel filter layer 312, and the sand and gravel filter layer 312 can filter fine impurities in the rainwater. The sand and gravel filter layer 312 can purify the rainwater by microorganisms and other means. The emergency water trough 300 and the purification water trough 310 The top of the inner wall is connected to a water inlet pipe 320 for water delivery. The water inlet pipe 320 is fixed with a solenoid valve at the water storage end connected to the emergency water trough 300 and the purification water trough 310. The upper end of the water inlet pipe 320 is connected to both sides of the inner wall of the seepage and drainage inlet cylinder 200. The rainwater filtered by the impurity filter frame 250 can enter the emergency water trough 300 and the purification water trough 310 through the water inlet pipe 320. The emergency water trough 300 can be directly opened when the rainfall needs to be accelerated when drainage is large. The bottom ends of the emergency water trough 300 and the purification water trough 310 are connected to the top of the inner wall of the transfer water trough 330 through a first short pipe. The bottom end of the inner wall of the transfer water trough 330 is connected to the top of the inner wall of the bottom water storage tank 400 through a second short pipe. The transfer water tank 330 is for temporarily storing rainwater, and the bottom water storage tank 400 is for storing rainwater again. The water can be directly discharged for use through the drain pipe 410. A group of return water pumps 420 can be provided inside the ground layer 100 and above the bottom water storage tank 400. The bottom suction pipe of the return water pump 420 is connected with the bottom water storage tank 400. The top water delivery pipe of the return water pump 420 can be connected with the opposite side of the top of the inner wall of the two transfer water tanks 330 through the return pipe 421. A drainage pipe 410 for drainage is provided on one side of the bottom end of the inner wall of the bottom water storage tank 400, or the rainwater is transported back to the transfer water tank 330 through the return water pump 420, so that the transfer water tank 330 can discharge the water into the bottom water storage tank 400 again.This ensures that the water is in a circulating state and prevents bacteria from growing in a static state. The return pipe 421 can also be connected to a disinfectant tank through a hose, so that the water can be transported into it for disinfection during the circulation process. The disinfectant tank can be set outside the ground layer 100.
[0024] The use process of the present invention is as follows: First, personnel can assemble and install the device according to the above instructions, and connect the power to the external device. After completion, personnel can control the electric telescopic rod 240 to retract through the controller, so that the electric telescopic rod 240 can pull the outer sealing ring 230 upward through the central block 241 and the connecting rod 242 to leak out the side water inlet 210, and the outside rainwater can enter the seepage and drainage water inlet cylinder 200 through the side water inlet 210. After being filtered by the filter screen and the impurity filter frame 250 in the side water inlet 210, the rainwater will enter the diverter plate 311 through the water inlet pipe 320, and then the diverter plate 311 will spray the rainwater evenly on the sand and gravel filter layer 312, and the sand and gravel filter will filter out the rainwater. The layer 312 and the microbial filtration layer 313 can filter and purify rainwater. After purification, the rainwater will first enter the transfer tank 330 and then be transported to the bottom water reservoir 400 by the transfer tank 330. If the bottom water reservoir 400 does not need to discharge the rainwater, the return water pump 420 can transport the rainwater back to the transfer tank 330, so that the transfer tank 330 can discharge the water into the bottom water reservoir 400, thereby ensuring the water treatment circulation state and avoiding the static breeding of bacteria. The return pipe 421 can also be connected to the disinfectant cylinder through a hose, so that some disinfectant can be transported into it for disinfection during the circulation of water. When necessary, the valve on the drain pipe 410 can be opened to discharge the rainwater.
[0025] When the drainage volume is large, personnel can completely drain the side water inlet 210, and then open the solenoid valve connecting the water inlet pipe 320 and the emergency water channel 300, so that the emergency water channel 300 can also transfer rainwater to the transfer water channel 330, and the transfer water channel 330 can transfer rainwater to the bottom water reservoir 400, and the water is quickly discharged from the bottom water reservoir 400;
[0026] When the device has been used for a long time, personnel can first lift the top cover plate 220, remove the outer sealing ring 230, and then lift the impurity filter frame 250 upward to clean the filtered impurities. At the same time, personnel can also open a groove at the bottom end of the side water inlet 210 on the ground layer 100, so that impurities filtered out of the side water inlet 210 can be stored in and out to prevent them from gathering at the side water inlet 210.
[0027] The above description is merely a preferred embodiment of the present invention. Anyone skilled in the art may utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
