[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1-6According to an embodiment of the present invention, an energy-saving building rainwater harvesting, storage, and reuse system includes a building body 1. An annular water trough 2 is installed at the top edge of the building body 1. A drain pipe 3 is connected to the bottom of the annular water trough 2. The bottom end of the drain pipe 3 is connected to an upper anti-clogging pretreatment mechanism 5 via a connecting sleeve 4. Rainwater from the roof of the building body 1 is collected through the annular water trough 2 and discharged into the upper anti-clogging pretreatment mechanism 5 through the drain pipe 3. The connecting sleeve 4 facilitates the connection between the drain pipe 3 and the upper anti-clogging pretreatment mechanism 5. After entering the upper anti-clogging pretreatment mechanism 5, the rainwater undergoes preliminary filtration, removing debris such as fallen leaves, thus preventing problems during later filtration. The filtration mechanism is prone to clogging. Mounting plates 6 are fixedly connected to both sides of the upper anti-clogging pretreatment mechanism 5. The upper anti-clogging pretreatment mechanism 5 is fixedly installed on the building body 1 via the mounting plates 6 and mounting nails 7. A connecting pipe 8 is connected to the bottom of the upper anti-clogging pretreatment mechanism 5. An overflow-proof treatment box 9 is connected to the bottom of the connecting pipe 8. After preliminary filtration, the rainwater enters the overflow-proof treatment box 9 through the connecting pipe 8. During subsequent treatment, it prevents rainwater from overflowing when there is excessive rainwater. The device of this application has a simple structure and is easy to use. It can filter debris such as leaves in the rainwater during collection to avoid clogging problems. At the same time, it can prevent rainwater from overflowing when the rainfall is heavy.

[0029] In one embodiment, please refer to the appendix to the specification. Figure 2As shown, the upper anti-clogging pretreatment mechanism 5 includes an outer housing 10. Bearings 11 are provided on both sides of the inner wall of the outer housing 10. A rotating shaft 12 connects the inner rings of the bearings 11. A drive blade 13 is fixedly sleeved at the center of the rotating shaft 12, and the drive blade 13 is located directly below the connecting sleeve 4. A large-pore filter screen 16 is provided inside the outer housing 10 below the drive blade 13. Both ends of the large-pore filter screen 16 are connected to the inner wall of the outer housing 10 through a movable mechanism 15. A drive shaft 17 is movably installed below the large-pore filter screen 16, and two eccentric wheels 48 are mounted on the drive shaft 17. One end of the rotating shaft 12 movably passes through the outer housing 10 and is provided with a bevel gear 14. One end of the drive shaft 17 movably passes through the outer housing 10 and is provided with a bevel gear 18. Both the bevel gear 14 and the bevel gear 18 are meshed with bevel gears 19. A connecting shaft 20 connects the bevel gears 19. A bearing 21 is fixedly sleeved on the connecting shaft 20. The outer ring of the bearing 21 is provided with a bracket fixedly connected to the outer wall of the outer housing 10. The outer wall of the outer housing 10 is provided with an outer protective shell 22 that covers the bevel gear 14, the bevel gear 18 and the bevel gear 19. When rainwater flows into the outer casing 10 from the connecting sleeve 4, it directly impacts the drive blade 13, causing the drive blade 13 to rotate. Simultaneously, the drive shaft 12 rotates, causing the bevel gear 14 to rotate. The bevel gear 14 then drives the bevel gear 3 19 meshing with it to rotate. In conjunction with the connecting shaft 20 and bearing 21, the other bevel gear 3 19 drives the bevel gear 2 18 meshing with it to rotate. The bevel gear 2 18 drives the drive shaft 17 to rotate, causing the two eccentric wheels 48 to rotate and strike the bottom of the large-pore filter screen 16. This, combined with the moving mechanism 15, generates up-and-down vibrations to prevent clogging.

[0030] In one embodiment, please refer to the appendix to the specification. Figure 3 As shown, the movable mechanism 15 includes a strip mounting plate 23 fixed to the inner wall of the outer casing 10. A sliding groove 24 is provided on the strip mounting plate 23, and a sliding block 25 is movably mounted within the sliding groove 24. Both ends of the sliding block 25 are equipped with return springs 26 connected to the top and bottom of the sliding groove 24, respectively. The large-pore filter screen 16 is connected to the sliding block 25 via a connecting block 27. The return springs 26 at both ends of the sliding block 25 increase the frequency of the large-pore filter screen 16's up-and-down vibration and provide support for the large-pore filter screen 16.

[0031] In one embodiment, please refer to the appendix to the specification. Figure 4 and 5As shown, the overflow-proof treatment box 9 is provided with a first partition 28 and a second partition 30. A rainwater filtration structure 29 is provided on one side of the first partition 28. The rainwater filtration structure 29 includes a connecting plate 36 that can be detachably embedded in the overflow-proof treatment box 9. A baffle 40 is provided on the outside of the connecting plate 36. A perforated filter screen 37 is provided on the inside of the connecting plate 36. An activated carbon filter element 38 is provided below the perforated filter screen 37. A bottom sterilization layer 39 is provided below the activated carbon filter element 38. The second partition 30 divides the overflow-proof treatment box 9 into a water storage chamber 31 and an overflow chamber 32. An opening 33 is provided at the bottom of the first partition 28. An opening 34 is provided at the top of the second partition 30. A floating drainage mechanism 35 is provided in the water storage chamber 31. The rainwater is filtered through the rainwater filtration structure 29, which uses a small-pore filter 37 for primary filtration, and then through an activated carbon filter 38 for secondary filtration to remove odors. The bottom sterilization layer 39 is used to sterilize the rainwater, ensuring its purity.

[0032] In one embodiment, please refer to the appendix to the specification. Figure 4 and 6 As shown, the floating drainage mechanism 35 includes a sealing plate 41 located inside the water storage tank 31. A float plate 45 is provided at the bottom of the sealing plate 41. Guide holes 42 are provided on both sides of the sealing plate 41. A guide post 43 is movably inserted through the guide holes 42. The top of the guide post 43 is connected to the top inner wall of the overflow prevention treatment box 9. A limiting block 44 is provided at the bottom of the guide post 43. When rainwater enters the water storage tank 31 through opening 1 33, the rainwater flows in from the bottom, causing the float plate 45 and the sealing plate 41 to float upwards. With the cooperation of the guide post 43 and the guide holes 42, the rainwater can be discharged from opening 2 34 into the overflow tank 32 for storage when the sealing plate 41 rises above opening 2 34. When there is less rainwater, the sealing plate 41 is lower than opening 2 34, adhering to the water surface, reducing the contact area between the rainwater and the air.

[0033] In one embodiment, please refer to the appendix to the specification. Figure 1 As shown, several fixing sleeves 46 are detachably fitted onto the connecting pipe 8. The fixing sleeves 46 are installed on the building body 1 via mounting crossbars 47. The fixing sleeves 46, in conjunction with the mounting crossbars 47, facilitate the installation and fixation of the connecting pipe 8.

[0034] In practical applications, rainwater from the roof of the building 1 is collected by the annular water trough 2 and discharged into the upper anti-clogging pretreatment mechanism 5 through the lower drain pipe 3. The connecting sleeve 4 facilitates the connection between the lower drain pipe 3 and the upper anti-clogging pretreatment mechanism 5. After entering the upper anti-clogging pretreatment mechanism 5, the rainwater is used as a power source to filter out debris such as leaves in the rainwater while avoiding the problem of clogging of the large-pore filter screen 16 itself. After preliminary filtration, the rainwater enters the overflow prevention lower treatment box 9 through the connecting pipe 8. During subsequent treatment, it prevents rainwater from overflowing when there is excessive rainwater. The device of this application has a simple structure and is easy to use. It can filter out debris such as leaves in the rainwater during rainwater collection to avoid clogging problems. At the same time, it can prevent rainwater from overflowing when the rainfall is heavy.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
