Wherein, the grid-shaped guide wall 2 is arranged in the front water pool 1, one side of the grid-shaped guide wall 2 is connected with the inner wall of the front water pool 1, and the grid-shaped guide wall 2 is provided with a plurality of cavities 21 communicated with the front water pool 1; the water inlet of the water pump suction pipe 3 extends into the cavity 21, the water outlet of the water pump suction pipe 3 is communicated with the water pump, and the water pump suction pipe 3 is used for enabling water in the front water pool 1 to flow into the water pump suction pipe 3 and pumping water in the water pump suction pipe 3 to the outside of the front water pool 1 and discharging the water under the suction effect of the water pump. Baffle 4 locates the one side that bars form guide wall 2 kept away from the inner wall of front pool 1 and extends along vertical direction, as shown in fig. 2 promptly, baffle 4 locates the right side of bars form guide wall 2. The one end of pressurized-water plate 5 is connected in the bottom of baffle 4, the other end absorbs water tub 3 slopes towards the water pump, so that form water conservancy diversion passageway 6 between the one side of 1 diapire in pond and the diapire of preceding pond 1 before the orientation of pressurized-water plate 5, thereby carry out the water conservancy diversion to the rivers in pond 1 before making, make rivers in preceding pond 1 through the water inlet of 6 water conservancy diversion passageways water conservancy diversion to water pump absorption pipe 3, and under the water conservancy diversion effect of water conservancy diversion passageway 6, the flow state of the rivers of the water inlet of water pump absorption pipe 3 is good, thereby avoid forming the swirl around water inlet department or baffle 4 of water pump absorption pipe 3, influence the operating efficiency and the life of water pump.
