When the conversion barrel 5 moves upwards under the buoyancy of the water in the outer barrel 1, the elastic force of the elastic pulling member 73 drives the conversion barrel 5 to rotate automatically, so that the conversion barrel can be opened automatically when the rainwater amount meets the design requirement, and the rainwater can flow out from the two second water outlet pipelines 33 quickly. A positioning block 71 is fixedly provided on the upper surface of the seal cap 51, and the positioning block 71 is located at the edge of the seal cap 51.
