The triangular top block pushes the triangular block 308 to move outward, and the triangular block 308 pushes the inner ends of the two support plates 309 hinged thereto to move outward. The outer ends of the two support plates 309 push the arc plates 310 to expand outward, so that the outer end surfaces of the two arc plates 310 completely fit the inner wall of the water-permeable pipe, further enhancing the supporting effect on the water-permeable pipe. When further adjusting the support position of the four curved plates 310, the electric cylinder I 301 works, the curved plate 310 drives the vertical plate 302 to move, the vertical plate 302 drives the large gear 303 to move, the motor III 313 drives the crossbar 304 to move, and the crossbar 304 drives the four curved plates 310 to move, thereby adjusting the support position of the curved plates 310; When grinding the water pipe, the electric grinder on the horizontal block 208 can grind the end and outer wall of the water pipe. When the position of the electric grinders on the four horizontal blocks 208 needs to be adjusted according to the thickness of the water pipe, the screw slider group 211 is started, driving the limit ring 210 to move, and the limit ring 210 simultaneously drives the four inclined rods 209 to move. The four inclined rods 209 drive the four horizontal blocks 208 to move outward at the same time, so that the electric grinders on the four horizontal blocks 208 move to the position matching the thickness of the water pipe to be ground. At this time, the four electric grinders are started to grind the water pipe. At the same time, the motor II 203 is started to drive the gear I2 04 and the wide gear II 205 rotate simultaneously, the gear I 204 drives the support block 206 to rotate, the support block 206 drives the four L-shaped frames 207 to rotate, the four L-shaped frames 207 drive the four cross blocks 208 to rotate, and the four cross blocks 208 respectively drive the four electric grinders thereon to rotate while working, thereby achieving the grinding of the water permeable pipe; at the same time, the wide gear II 205 drives the large gear 303 to rotate, the large gear 303 drives the cross bar 304 to rotate, and the cross bar 304 drives the four curved plates 310 to rotate, ensuring that when the water permeable pipe is ground, the four curved plates 310 always support the inner wall of the grinding position of the water permeable pipe, thereby ensuring the grinding effect while saving manpower; When the water pipe is being polished, the seven nozzles on the inner wall of the second annular frame 402 spray water on the water pipe in all directions, effectively reducing the temperature of the water pipe during polishing and preventing deformation of the water pipe. The sprayed water flows into the storage box 401 for collection, preventing waste of resources. When the water permeable pipe needs to be moved inward, the electric wheel 106 is started to drive the water permeable pipe to move inward. Due to the assistance of the driven wheel on the top rod Ⅰ103, the water permeable pipe is easier to move, so that the grinding distance of the end of the water permeable pipe can be freely adjusted; when the water permeable pipe is polished, it needs to be moved out of the equipment. The water permeable pipe is manually grasped. At this time, the electric wheel 106 works in the opposite direction, driving the water permeable pipe to exit the first annular frame 102, waiting for the next water permeable pipe to be clamped and polished.
