The guide rod moves through the limit block.

[0011] Optionally, the position adjusting block and the lead screw are connected by a thread, and the rotation of the lead screw causes the position adjusting block to move.

[0012] Optionally, the top of the mounting base is triangular, and the mounting base is vertically fixedly installed on the end of the building roof near the movable plate. The drive shaft moves through the top of the mounting base and is fixedly connected to the second bevel gear. A handwheel is fixedly connected to the end of the second bevel gear away from the mounting base.

[0013] In summary, this application includes the following beneficial technical effects: This invention achieves dust prevention by setting up a movable plate in conjunction with a drive component, thus covering the collection tank on sunny days, preventing rainwater from being contaminated by leaves and dust, and ensuring that the recycled water quality is not polluted.

[0014] This utility model achieves efficient water collection by opening a collection trough on a fixed plate with a trapezoidal bottom end, and the fixed plate is connected to a drain pipe on one side.

[0015] This invention employs a transmission combination of a lead screw and bevel gear, along with a guide rod for limiting, to ensure precise positioning of the moving plate under complex weather conditions (such as strong winds and heavy rain).

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses a rainwater harvesting and storage structure for green building roofs. For example... Figure 1 As shown, the building includes a main body 10 and a roof 11. The roof 11 is installed on the top of the main body 10. Both ends of the roof 11 are equipped with rainwater interception components 12, which can be deployed on rainy days to intercept and collect rainwater. The rainwater interception component 12 includes a movable plate 16 and a fixed plate 17. A drain pipe 13 is connected through the side of the fixed plate 17 away from the movable plate 16 for transporting rainwater. A collection tank 14 is installed below the main body 10. The collection tank 14 is connected to the drain pipe 13. Rainwater is collected in the collection tank 14 through the drain pipe 13 and stored for later use, achieving green environmental protection.

[0020] Please see Figure 3 The fixed plate 17 is fixedly connected to the building roof 11 to ensure the stability of the device. The top of the movable plate 16 is on the same slope as the building roof 11. A collection trough 18 is provided at the top of the fixed plate 17. When rainwater passes through the fixed plate 17, it falls directly into the collection trough 18. The bottom of the collection trough 18 is trapezoidal to facilitate the collection of rainwater and its flow into the drain pipe 13.

[0021] Please see Figure 4 A drive assembly 15 for position adjustment is provided between the movable plate 16 and the fixed plate 17. The drive assembly 15 includes a position adjustment block 22, a connecting block 19 and a drive unit. The movable plate 16 can be moved by setting the drive unit. When it is not raining, the movable plate 16 can cover the fixed plate 17 to prevent dust, impurities or leaves from falling into the collection tank 18 and contaminating the rainwater collected in the collection tank 14.

[0022] Please see Figure 4 and Figure 5Two sets of first fixed piles 20 and second fixed piles 23 are fixedly installed at the bottom of the fixed plate 17. A screw 21 is movably installed between one set of first fixed piles 20 and second fixed piles 23. One end of the connecting block 19 is fixedly connected to the moving plate 16. The position adjusting block 22 is movably inserted through the screw 21, and the screw 21 is fixedly inserted through the first bevel gear 24. Thus, the rotation of the first bevel gear 24 drives the screw 21 to rotate. There are two sets of connecting blocks 19. Both sets of connecting blocks 19 are fixedly connected to the bottom of the corresponding moving plate 16. The rotation of the screw 21 causes the position adjusting block 22, the connecting block 19 and the moving plate 16 to move as a whole. A guide rod is fixedly installed between the other set of first fixed piles 20 and second fixed piles 23. The other set of connecting blocks 19 is fixedly connected to a limit block. The guide rod movably inserts through the limit block, thus limiting and guiding the movement of the moving plate 16 and improving the stability of the moving plate 16 during the movement process.

[0023] Please see Figure 5 The drive unit includes a second bevel gear 28, a drive shaft 26, and a mounting base 25. The second bevel gear 28 meshes with the first bevel gear 24, and the two gears are in a transmission relationship. The position adjustment block 22 is threadedly connected to the lead screw 21, and the rotation of the lead screw 21 causes the position adjustment block 22 to move. When the second bevel gear 28 rotates, it drives the lead screw 21 to rotate through the first bevel gear 24. The lead screw 21 causes the position adjustment block 22, the connecting block 19, and the moving plate 16 to move as a whole. The top of the mounting base 25 is triangular, and the mounting base 25 is vertically fixed to one end of the building roof 11 near the moving plate 16. The drive shaft 26 passes through the top of the mounting base 25 and is fixedly connected to the second bevel gear 28. A handwheel 27 is fixedly connected to the end of the second bevel gear 28 away from the mounting base 25. The user rotates the handwheel 27 to drive the drive shaft 26 to rotate, and the rotation of the drive shaft 26 synchronously drives the second bevel gear 28.

[0024] The implementation principle of the rainwater harvesting and storage structure for a green building roof in this application embodiment is as follows: In use, the fixing plate 17 is fixedly installed on both sides of the building roof 11. The fixing plate 17 is connected to the corresponding drainage pipe 13, and the drainage pipe 13 is connected to the corresponding collection tank 14. When it rains, the rainwater first washes away the dust on the surface of the building roof 11. Then, the handwheel 27 is rotated by hand to drive the drive shaft 26 to rotate. The top of the drive shaft 26 is fixedly connected to the second bevel gear 28. The second bevel gear 28 is engaged with the first bevel gear 24. The position adjustment block 22 moves through the lead screw 21, and the lead screw 21 is fixedly connected through the first bevel gear 24. Thus, the rotation of the lead screw 21 drives the position adjustment block 22, the connecting block 19, and the moving plate 16 to move as a whole, exposing the collection trough 18 on one side of the fixing plate 17. Rainwater flows along the building roof 11, through the collection trough 18, and is collected in the collection tank 14 through the drainage pipe 13.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
