6. A rainwater drainage device for rainwater collection as claimed in claim 1, wherein the piston is further connected with a filter screen.
7. The rainwater drainage device for rainwater collection according to claim 6, wherein the surface of the piston is provided with a jogging groove, the filter screen is jogged in the jogging groove, and the side surface of the filter screen is level with the side surface of the piston.
8. A rainwater drainage device for rainwater collection according to claim 1, 6 or 7, wherein an impact plate is further arranged in the water inlet pipe, and the top of the impact plate is hinged with the inside of the water inlet pipe.
9. A method of using a rainwater drainage device for rainwater collection, characterized in that a rainwater drainage device for rainwater collection as claimed in any one of claims 1 to 8 is used, comprising the steps of:
step one: in the early stage of rainfall, the initial rainwater flows into the water inlet pipe, the flow of the initial rainwater is insufficient to push the piston to move due to the obstruction of the piston, the initial rainwater can only be discharged through the first water outlet, flows into the partition plate, flows to the drainage pipe through the water inlet formed by the partition plate, and is discharged by the drainage pipe;
step two: along with the increase of the rainfall, the rainwater flows into the water inlet pipe, the rainwater impacts the piston, and the flow of the rainwater is enough for the piston to compress the spring and move rightwards and drive the sleeve to move rightwards; when the sleeve moves, the second water outlet moves right along with the sleeve and enters the box body, so that the second water outlet is communicated with the inside of the box body; when the sleeve moves right, the connecting rod is driven to move right, and the connecting rod moves right to drive the baffle to move right and plug the first water outlet; so that the rainwater flows into the water collecting barrel through the second water outlet; along with the continuous increase of water in the water collecting barrel, the water collecting barrel overcomes the resistance of the balancing weight and rotates, the water collecting barrel drives the balancing weight to move upwards in the rotating process, meanwhile, the balancing weight also drives the plugging plate to move rightwards through the second pull rope, the tension spring generates elasticity, and the plugging plate plugs the water through hole; as the water inflow is far greater than the water drainage at the water port, the rainwater in the box body is continuously increased until the rainwater is discharged from the water outlet and is collected.
