The arrangement of 1 inlet tube 2 and 3 outlet pipes 3 realizes that a share of intaking divides into 3 shares of water. The incoming water enters the device body 1 through the water inlet pipe 2, is subjected to energy dissipation through the rectifying plate 4, is proportionally split by the splitting weir plate 6, enters each splitting area 5, and then is discharged through the water outlet pipe 3. The weir crest 7 of this example reposition of redundant personnel weir plate 6 adopts the triangle weir crest, and the 7 numbers of weir crest of the reposition of redundant personnel weir plate 6 that each outlet pipe 3 corresponds through the lift control of adjusting plate 12 on adjusting the reposition of redundant personnel weir plate 6, then 7 numbers of weir crest ratios of the reposition of redundant personnel weir plate 6 that each outlet pipe 3 corresponds are 3 flow ratios of each outlet pipe promptly.
