[0025] In use, when rainwater falls into the rainwater well body 1 through the rainwater opening formed in the moving cover 9, the rainwater impacts the spiral blade 4, so that the spiral blade 4 rotates. Along with the rotation of the spiral blade 4, the moving rod 6 is driven to move along the thread line on the spiral blade 4. Due to the continuous impact of the rainwater, the spiral blade 4 keeps rotating in the same direction, and the moving rod 6 finally moves to the end of the thread line and keeps the position unchanged. The lifting of the moving rod 6 drives the two push rods 7 to move synchronously, since the two push rods 7 are detachably connected to the moving cover 9 through the two bolts 8, the two push rods 7 drive the moving cover 9 to rise synchronously when the two push rods 7 are lifted. Since the moving cover 9 is fixed to the telescopic rod 10, the telescopic rod 10 is connected to the net rack 11, and the moving cover 9 drives the net rack 11 to move synchronously when the moving cover 9 rises, so that the nylon net 12 is opened to form a cylindrical protective net, which blocks the fallen leaves and impurities outside the rainwater well body 1 and effectively prevents the impurities from entering the rainwater well, so as to avoid the impurities from being accumulated in the well and reduce the risk of urban waterlogging caused by the blockage of the drainage pipeline by the impurities.
