Detailed Description

Given by fig. 1-2, the utility model discloses a river course model body 2, river course model body 2's left end is equipped with initial waters 20, the side fixed mounting of initial waters 20 has water stabilizing hole board 21, water stabilizing hole board 21's surface is equipped with a plurality of through-hole, river course model body 2's middle part is equipped with and blocks water weir 22, river course model body 2's right-hand member is equipped with cistern 23, the inside fixed mounting of cistern 23 has the drinking-water pipe, the fixed intercommunication of one end of drinking-water pipe has immersible pump 24, the fixed intercommunication of output of immersible pump 24 has the outlet pipe, outlet pipe fixed mounting is in the inside of initial waters 20, initial waters 20's inner chamber bottom is equipped with absorption threshold 25, absorption threshold 25's cross section is upstream face upright trapezoidal, 2 inner chamber's in river course model body both sides all are equipped with curve river course 26, river course model body 2's the slope is 1 2000.

The curved river channel 26 is wavy, and the wavy concave parts at the two sides of the curved river channel 26 are opposite to the wavy convex parts.

The water blocking weir 22 is fixedly arranged on the wave surface of the curved river channel 26, a water discharge opening 27 is arranged between the water blocking weir 22 and the curved river channel 26 on the other side, and a plurality of water blocking weirs 22 are arranged.

The width of the drain opening 27 is one eighth of the width between the inner walls of the river channel model body 2, and is the width of a vertical seam type fishway.
