Example 2
A rainwater circulation method using the rainwater collection circulation system in embodiment 1, comprising the steps of:
step 1, collecting rainwater and filtering garbage; rainwater is collected by the rainwater well 3 during raining, garbage is filtered through the grating of the rainwater well 3 and the primary filter screen 4, when the liquid level sensor 6 in the rainwater well 3 senses that the liquid level reaches a set value, the electric telescopic rod 10 stretches and pushes the garbage pushing plate 9 to move into the crushing box 5, and the garbage filtered on the primary filter screen 4 is pushed into the crushing box 5. When the garbage pushing plate 9 pushes the garbage baffle 7, the garbage baffle 7 rotates into the crushing box 5, and the tension spring 8 stretches; when the electric telescopic rod 10 is lengthened to a set value, the electric telescopic rod is shortened, the garbage pushing plate 9 is driven to reset, the tension spring 8 drives the garbage baffle 7 to reset, and rainwater is prevented from entering. When the garbage baffle 7 pushes garbage into the crushing box 5, the garbage falls between the two crushing cutters 12 through the guide plate 11, the crushing motor 13 drives the crushing cutters 12 to crush the garbage, the crushed garbage falls on the conveying belt 14, and rainwater in the crushing box 5 flows into the rainwater well 3 through the sewer 17; the filtered rainwater flows to the secondary filtering mechanism 1.
Step 2, filtering dust by rainwater and storing; the rainwater after the primary filtration continues to flow into the fixed cylinder 29 of the secondary filtration mechanism 1 and flows into the clean water tank 43 through the clean water filter screen 36; when the rainwater flow exceeds a set threshold, the rainwater in the water filtering tank presses down the water purifying filter screen 36, the water purifying filter screen 36 descends and rotates along the spiral track 30, the telescopic rod is driven to extend when the water purifying filter screen 36 descends, and meanwhile the water purifying filter screen 36 drives the diversion baffle 37 to rotate together with the water purifying filter screen; the diversion port 34 and the sand washing port 39 are opened together, rainwater flows into the buffer pipeline 35 and the buffer box 44 through the diversion port 34 and the sand washing port 39, and sediment on the water purification filter screen 36 is washed down when the rainwater flows through the sand washing port 39, so that the water flow of the water purification filter screen 36 is increased. If the rainwater in the fixed cylinder 29 is reduced, the water purifying filter screen 36 rises and resets under the action of the spring 32, and the shunt opening 34 and the sand flushing opening 39 become smaller until being closed; if the rainwater flow rate continues to increase, the rainwater in the fixed cylinder 29 increases again, the water purifying filter screen 36 continues to descend, the rotation angle of the diversion baffle 37 increases, and the area of the diversion opening 34 is increased until the diversion opening 34 and the sand outlet are completely opened. When the rainwater level in the buffer tank 44 is higher than that in the clean water tank 43, the partition plate 42 moves towards the clean water tank 43 along the fixed slide bar 50 under the action of water pressure, and meanwhile, the partition plate 42 drives the soft rope 66 to be released from the reel 64 through the pulley 63, and the soft rope 66 drives the reel 64 to rotate; when the rainwater in the fresh water tank 43 is higher than the buffer tank 44, the diaphragm 42 moves toward the buffer tank 44 under the action of the water pressure, and the volumes of the buffer tank 44 and the fresh water tank 43 are automatically adjusted. When the flow rate of the rainwater is 0 as sensed by the flowmeter when the rainwater only flows to the clean water tank 43, the rainwater does not flow to the buffer tank 44 any more, the reel motor 65 drives the reel 64 to retract the soft rope 66, the soft rope 66 drives the partition plate 42 to move towards the reel 64 through the pulley 63, and the rainwater in the buffer tank 44 flows into the clean water tank 43 through the buffer filter screen 46 and the one-way valve 47. When the partition plate 42 moves, the waterproof cloth is driven to move, the connecting rod 54 rotates and drives the movable slide rod 51 to slide on the water storage tank 41, the distance between the movable slide rod 51 and the fixed slide rod 50 changes, and meanwhile, the movable slide rod 51 drives the longitudinal and transverse distances between the movable ring 53 and the fixed ring 52 to change, so that the side surface of the waterproof cloth is regularly stretched or folded, and further the whole waterproof cloth is regularly stretched or folded.
Step 3, utilizing rainwater; the water in the clean water tank 43 is supplied to the urban public greening area and the district greening area for irrigating plants.
Step 4, conveying the filtered garbage; after rain, a worker opens the movable cover plate 21, pulls the top of the lifting pipe 22 and the discharging pipe 28 out of the placing groove 20 upwards, the movable conveying opening 23 is communicated with the fixed conveying opening 19 after the lifting pipe 22 ascends, and the lifting section 24 is driven to ascend together with the lifting section when the lifting pipe 22 ascends, so that the conveying shaft stretches; starting a conveying belt 14 and a conveying motor 27, conveying broken garbage to the spiral blade 25 by the conveying belt 14, conveying the garbage upwards by the spiral blade 25 driven by the conveying motor 27, outputting the garbage from a discharging pipe 28, and collecting the garbage by staff; after the garbage is completely discharged, a worker presses the top of the lifting pipe 22 and the discharging pipe 28 down into the placing groove 20, and closes the movable cover plate 21.
