The telescopic rod 403 does continuous telescopic motion, so that the mounting shaft 4 and the cleaning assembly 5 are driven to move back and forth, the garbage on the rainwater grate can be cleaned in the process of moving back and forth of the cleaning assembly 5, in addition, in the cleaning process, water in the water tank 20 is continuously sprayed onto the rainwater grate through the spray opening 24 of the spray pipe 23, soil and fine impurities on the rainwater grate can be flushed onto the filter screen 11, the filter screen 11 retains smaller garbage on the filter screen 11, and the water flows into the inspection well through the filter screen 11, so that not only can the larger garbage above the rainwater grate be cleaned, but also the sludge and the like on the rainwater grate can be flushed, and the cleaning of the rainwater grate is more efficient; at the in-process of installation axle 4 to thick removal, scraper blade 19 of scraper 502 below contacts with filter screen 11 all the time, can scrape the collection string bag 14 of rear side gradually through the impurity on the filter screen 11 in, filter screen 11 can filter less rubbish from this, prevents in rubbish enters into the inspection shaft, blocks up the inspection shaft to, scraper blade 19 also can in time clear away the rubbish on the filter screen 11, can effectively prevent the jam of filter screen 11.

After the rainwater grate clearance is accomplished, can inwards promote two montants 10 around, make two montants 10 remove to the direction that is close to each other, when the innermost of its displacement of two perpendicular trunk removals, the upper end of montant 10 is located transverse groove 26 in, and when two montants 10 removed to the direction that is close to each other, under the effect of torsional spring torsion, can make filter screen 11 coil, after montant 10 removed transverse groove 26 in, then rotate turning block 25, filter screen 11 that turning block 25 drove the below is rotatory 90, make filter screen 11 the cross axle 17 with water inlet 2 be parallel, at last with filter screen 11 along water inlet 2 take out can.
