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.

Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the training for sediment structure with suspended sediment collecting function of the present embodiment, including it is installed on water conservancy projects
The training for sediment main body of water inlet 1, the upper surface of training for sediment main body carry the first water conservancy diversion plane 2 set gradually, domatic on the first water conservancy diversion
3rd, the first water conservancy diversion Caused by Sloping Surfaces 4, the second water conservancy diversion plane 5, the domatic 6, second water conservancy diversion Caused by Sloping Surfaces 7 and export mouth plane 8 on the second water conservancy diversion,
The height of first water conservancy diversion plane 2, the second water conservancy diversion plane 5 and export mouth plane 8 reduces successively;Interval is provided with more in training for sediment main body
Block training for sediment plate 10, training for sediment plate 10 are vertically arranged with respect to the upper surface of training for sediment main body, and collection is provided between adjacent training for sediment plate 10
Net cage 9, the top that net cage 9 is located at the first water conservancy diversion Caused by Sloping Surfaces 4 and the second water conservancy diversion Caused by Sloping Surfaces 7 is collected, collect the inclined bottom surface of net cage 9
Set, its incline direction is identical with the first water conservancy diversion Caused by Sloping Surfaces 4 and the second water conservancy diversion Caused by Sloping Surfaces 7.
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.
