One water conservancy diversion Caused by Sloping Surfaces and the second water conservancy diversion Caused by Sloping Surfaces are identical.
Further improvement as above-mentioned technical proposal：
The training for sediment plate carries more bending structures, including alternate straight training for sediment face and deviation training for sediment face, straight training for sediment face
It is consistent with the water (flow) direction of water inlet, deviation training for sediment towards straight training for sediment face side deviation, positioned at the first water conservancy diversion Caused by Sloping Surfaces
The deviation in deviation training for sediment face and the deviation training for sediment face on the second water conservancy diversion Caused by Sloping Surfaces is in opposite direction.
Middle deviation positioned at from the end of outermost training for sediment plate to the training for sediment main body.
The collection net cage is connected by support bar and the training for sediment main body.
The technical effects of the invention are that：
The present invention uses height ladder and more slope structures, realizes effective deposition to silt, prevents silt with current stream
It is dynamic, height hierarchic structure, the hydrocone type of silt is absorbed beneficial to the later stage；Training for sediment harden structure is set, is easy to training for sediment；The inclination of setting
Net cage is collected, is advantageous to the filtering of suspended sediment, prevents from impacting generator, and suspended sediment can be received
Collection.
