As shown in fig. 1 to 2, a diversion canal with sand blocking function comprises a canal 1, an inlet baffle 2, an outlet baffle 3, a floating baffle 4, a floating device 5 and an outlet grid 6, wherein the inlet baffle 2 and the outlet baffle 3 are respectively and fixedly installed at a water inlet and a water outlet of the canal 1, the inlet baffle 2 and the outlet baffle 3 are both located below a horizontal plane, the floating baffle 4 is installed at the water inlet in a vertically sliding manner, the floating baffle 4 is tightly attached to the side surface of the inlet baffle 2, when the floating baffle 4 slides to the top, the bottom of the floating baffle 4 is overlapped with the upper part of the inlet baffle 2, the floating baffle 4 is connected with the floating device 5, the floating baffle 4 is located above the inlet baffle 2, the floating baffle 4 is located below a water surface, the floating baffle 4 can move up and down along with the water level under the action of the floating device 5, the floating device 5 floats on the water surface, the outlet grid 6 is fixedly installed right above the outlet baffle 3, and the outlet 6 is higher than the grid.

The working principle is as follows: the floating baffle is arranged below the water surface, and water in the river channel can flow into the channel from the upper part of the floating baffle. When a ship passes through the floating baffle, the floating pontoon can ascend or descend by the generated water flow surge, so that the floating baffle is driven to ascend and descend together. Because the silt density is greater than the water, the bottom of the flow will have far more silt than the top. And the floating baffle can lift along with the water level to can block the silt that is located the rivers bottom, make it can not get into in the channel, thereby can reduce the silt volume in the channel. An outlet baffle is also arranged at the water outlet of the channel, so that the sediment deposition in the channel is facilitated. And set up the export grid above the baffle of going out water, locate export grid department with the water inlet of water pump to make the water that contains less sand volume get into the water pump, reduced the silt that gets into in the water pump. When a certain amount of silt is accumulated in the channel, the channel needs to be cleaned in time to prevent the thickness of the silt layer from exceeding the height of the outlet baffle. This inlet channel with keep off husky function can reduce the silt particle volume that gets into in the channel, has not only reduced the work load of carrying out the desilting to the channel, can reduce the inspiratory silt particle volume of water pump moreover, has improved the life of water pump.
