Because after filtering the rainwater, impurity can pile up on rubber pad 13, start first motor 172 this moment, drive adjusting disk 171 rotates, drive swinging arms 174 swing, and then drive first montant 161 and go up and down, along with the lift of a plurality of first montants 161, the middle part that can promote rubber pad 13 through first roof 162 goes up and down, because the both ends of rubber pad 13 are equipped with wave soft board 15, along with the middle part lift of rubber pad 13, can drive the vibrations of rubber pad 13, so that will pile up in the impurity on rubber pad 13 surface and shake off to the collection sediment fill 124 in, the collection to impurity has been realized.

When the middle part of rubber pad 13 goes up and down, because the bottom of second montant 18 passes through the spring 21 to be fixed in the groove bottom wall of recess 20, and then can provide the vibration power for the middle part of rubber pad 13 through second roof 19, strengthened the vibrations effect of rubber pad 13 to shake off impurity fast in to slag collection fill 124.

When rainwater enters the treatment box 7, impurities in the rainwater can be filtered for the second time by utilizing the support box 221 and the hollow fiber reverse osmosis membrane 222, the filtering effect is good, after the hollow fiber reverse osmosis membrane 222 is used for a long time, a large amount of impurities are accumulated on the upper surface of the hollow fiber reverse osmosis membrane 222, the second motor in one cavity 224 is started to drive the upper roll shaft 231 and the two upper driving wheels 233 to rotate, the lower roll shaft 232 and the two lower driving wheels 234 are driven to synchronously rotate through the transmission belt, the hollow fiber reverse osmosis membrane 222 with impurities can then be rolled into one of the cavities 224, and simultaneously activates a second motor in another cavity 224, drives a conveyor belt 235 through an upper roller shaft 231, an upper driving wheel 233, a lower roller shaft 232 and a lower driving wheel 234, and then the clean hollow fiber reverse osmosis membrane 222 can be unreeled into the supporting box 221 so as to filter rainwater subsequently.

When in rolling hollow fiber reverse osmosis membrane 222 with impurity to cavity 224, utilize scraper blade 241 and sponge can strike off the impurity of adhesion on hollow fiber reverse osmosis membrane 222 to the space of gathering materials in, pile up too much back when the impurity in the space of gathering materials, impurity can get into holding tank 244 inside, strikes off through the impurity with hollow fiber reverse osmosis membrane 222 upper surface to reuse hollow fiber reverse osmosis membrane 222, practiced thrift the resource.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
