Example
[0028] Working Principle: When using this invention, rainwater is collected through the rainwater collection tank 2. After entering the rainwater collection tank 2, the rainwater is guided by the guide plate 6 and then filtered through the first filter screen 18. Simultaneously, the control panel 3 controls the first motor 7 to rotate the reciprocating screw 8. The reciprocating screw 8 drives the first threaded block 9 to slide back and forth on the first limit rod 10. When the first threaded block 9 touches the first empty slot 16 on the left, the control panel 3 controls the electromagnet 15 to be de-energized. At this time, the first spring 14 applies a force to the square magnet block 12, causing the square magnet block 12 to slide downwards in the square slot 11. The cleaning plate 13 cleans the first filter screen 18. Meanwhile, the first motor 7 is controlled to rotate. The reciprocating screw 8 drives the first threaded block 9 to move to the right, thereby cleaning the impurities on the first filter screen 18 and then cleaning the impurities into the garbage collection bin 19. When the first threaded block 9 touches the first empty slot 16 on the right, the electromagnet 15 is energized by the rainwater collection bin 2. At this time, the electromagnet 15 attracts the square magnet block 12, thereby causing the square magnet block 12 to slide upward in the square slot 11 and compress the first spring 14. At this time, the cleaning plate 13 moves away from the first filter screen 18, and then the first threaded block 9 is moved to the leftmost position. The cleaning operation is repeated. The rainwater filtered by the first filter screen 18 is filtered by the purification grit 23 in the placement plate 21, and then purified by the purification plate 24 and the filter element 25. After being adsorbed by the activated carbon adsorption layer 26, the odor is finally absorbed and transported into the storage chamber 28 through the guide chamber 27. As the amount of rainwater in the storage chamber 28 increases, the floating objects 29 will float. The floating objects 29 will drive the first gear 31 to rotate through the first rack 32. The first gear 31 will push the first triangular block 35 through the first fixed plate 30 and the top plate 34, thereby causing the first connecting block 36 at the bottom of the first triangular block 35 to slide on the limiting double rod 37. The first triangular block 35 can push the second triangular block 39 to move upward. The second triangular block 39 will drive the two connecting rods 38 to slide upward within the limiting double rod 37. The connecting rods 38 can drive the track plate 40 to push the rain shield 42, so that the rain shield... 42 slides within the limiting groove 41. When the rainwater storage in the storage chamber 28 reaches its maximum value, the rain shield 42 will completely cover the inlet of the rainwater collection box 2 to prevent excessive rainwater. When it is necessary to irrigate the planting layer 5, the control panel 3 controls the water pump 50 to extract the rainwater from the storage chamber 28 and then irrigate it through the nozzle 49. At the same time, the cylinder 44 is controlled to drive the second rack 46. When the second rack 46 moves upward, it will be limited by the telescopic rod 45. Then, the second rack 46 drives the second gear 48. The second gear 48 can drive the nozzle 49 to perform variable angle irrigation. By controlling the output end of the cylinder 44 to reciprocate to drive the second gear 48, the nozzle 49 can perform multi-angle adjustable irrigation.
