[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1-3 As shown, this utility model provides a technical solution:

[0021] An easily expandable rainwater harvesting module includes a housing 1. Side grooves 11 are symmetrically formed on both sides of the housing 1, and a top groove 12 is formed on the top of the housing 1. A rainwater tank 4 is placed inside the housing 1 below the top groove 12. A drainage branch pipe 42 is fixedly installed on one side of the rainwater tank 4, and a valve 5 is fitted onto the drainage branch pipe 42. A filter frame 7 is held in place on the upper part of the rainwater tank 4. Slots 43 are symmetrically formed on the top of the rainwater tank 4. Handles 71 are symmetrically arranged on both sides of the upper part of the filter frame 7 and are engaged in the slots 43. Handles 41 are symmetrically fixed on both sides of the rainwater tank 4. A rainwater collection hopper 2 is fixedly installed on the top of the housing 1, and the rainwater collection hopper 2 extends through its outer wall. The support column 21 is fixed to the top of the box 1. A through groove 22 is opened in the middle of the rainwater collection hopper 2, and the through groove 22 is connected to the top groove 12. Rain guide grooves 23 are symmetrically and obliquely opened on both sides of the upper part of the rainwater collection hopper 2, and the rain guide grooves 23 are connected to the through groove 22. An extension plate 3 is slidably installed in the rain guide groove 23, and the extension plate 3 is locked and fixed in the rain guide groove 23 by bolts 6. A buckle groove 31 is opened at the bottom of the upper end of the extension plate 3. By sliding the extension plate 3 upward along the rain guide groove 23 and screwing the upper end of the bolt 6 into the threaded hole opened at the bottom of the lower end of the extension plate 3, the extension plate 3 is locked and fixed in the rain guide groove 23, and rainwater can be collected through the extension plate 3. The rainwater collection hopper 2 expands its rainwater receiving area, making operation convenient and improving rainwater collection efficiency. By removing the rainwater tank 4 from the tank 1, the filter frame 7 can be removed from the rainwater tank 4, facilitating cleaning of the inside of the filter frame 7. In use, rainwater can be collected through the rainwater collection hopper 2 during rainy days. Rainwater falling on the rainwater collection hopper 2 can fall into the filter frame 7 through the through groove 22 and the top groove 12, and after being filtered by the filter frame 7, it enters the rainwater tank 4 for collection. When it is necessary to expand the rainwater receiving area of ​​the rainwater collection hopper 2, the expansion plate 3 can be pulled outward along the rain guide groove 23 by manually fastening the fastening groove 31 and tightening one end of the bolt 6. Screw the extension plate 3 into the threaded hole at the bottom to fix the extension plate 3. The rainwater collection area of ​​the rainwater collection hopper 2 can be expanded by the extension plate 3, so that the rainwater falling on the extension plate 3 can enter the rain guide channel 23 along the extension plate 3 and then enter the through channel 22. The rainwater filtered by the filter frame 7 can settle inside the rainwater tank 4, making the rainwater cleaner. When the rainwater in the rainwater tank 4 needs to be used, the rainwater can be discharged through the drain branch pipe 42 by manually opening the valve 5. After a period of time, the rainwater tank 4 can be slid out from the side of the tank body 1 and the filter frame 7 can be removed from the rainwater tank 4 for cleaning.

[0022] A drain window 44 is provided on the other side of the rainwater tank 4. The bottom of the drain window 44 is flush with the bottom of the inner side of the rainwater tank 4. The drain window 44 is sealed by a U-shaped sealing plate 8. Guide grooves 45 are symmetrically provided on the front and rear sides of the rainwater tank 4. The two ends of the U-shaped sealing plate 8 slide along the guide grooves 45. A nut seat 81 is fixedly provided at the center of the top of the U-shaped sealing plate 8. A screw 9 is threaded through the nut seat 81. One end of the screw 9 is rotatably connected to the rainwater tank 4 through a bearing, and a hand crank 91 is fixedly provided at the other end of the screw 9. A sealing gasket 10 is fixed on the inner wall of the U-shaped sealing plate 8 to seal. The pad 10 abuts against the outer wall of the rainwater tank 4. By rotating the screw 9 counterclockwise, the U-shaped sealing plate 8 is moved away from the drain window 44, which opens the drain window 44, making it easier for personnel to clean the sediment at the bottom of the rainwater tank 4 and improving the working effect. After removing the filter frame 7 from the rainwater tank 4, the screw 9 can be rotated counterclockwise by rotating the hand crank 91. The rotation of the screw 9 will move the U-shaped sealing plate 8 away from the drain window 44, opening the drain window 44. At this time, personnel can clean the sediment at the bottom of the inside of the rainwater tank 4 from the drain window 44.

[0023] Working principle: During use, rainwater can be collected through the rainwater collection hopper 2 in rainy weather. Rainwater falling on the rainwater collection hopper 2 can fall into the filter frame 7 through the through groove 22 and the top groove 12, and after being filtered by the filter frame 7, it enters the rainwater tank 4 for collection. When it is necessary to expand the rainwater collection area of ​​the rainwater collection hopper 2, the extension plate 3 can be manually fastened by the latch groove 31 and pulled outward along the rain guide groove 23. One end of the bolt 6 is screwed into the threaded hole at the bottom of the extension plate 3 to fix the extension plate 3. The rainwater collection area of ​​the rainwater collection hopper 2 can be expanded through the extension plate 3, so that the rainwater falling on the extension plate 3 can enter the rain guide groove 23 along the extension plate 3 and then enter the through groove 22. In section 2, rainwater filtered by filter frame 7 can settle inside rainwater tank 4, making the rainwater cleaner. When rainwater in rainwater tank 4 needs to be used, valve 5 can be manually opened to allow rainwater to be discharged through drain branch pipe 42. After a period of time, rainwater tank 4 can be slid out from the side of tank body 1 and filter frame 7 can be removed from rainwater tank 4 for cleaning. After removing filter frame 7 from rainwater tank 4, the screw 9 can be rotated counterclockwise by turning hand crank 91. Rotation of screw 9 can move U-shaped sealing plate 8 to the side away from drain window 44, opening drain window 44. At this time, personnel can clean the sediment at the bottom of the inside of rainwater tank 4 from drain window 44.
