[0025] When it is necessary to dissipate energy of the torrent at the outlet of the spillway of the silt dam, the debris in the torrent is filtered through the coarse filter 4, and the filtered torrent enters the outer shell 1 through the flood discharge pipe 2, and the torrent pushes the S-shaped guide plate 7 so that the S-shaped guide plate 7 drives the rotating rod 6 to rotate, and the torrent is buffered by the rotation of the S-shaped guide plate 7, and then the torrent enters the drainage box 9 after being filtered by the fine filter 8, and part of the torrent pushes the second guide plate 13 so that the second guide plate 13 drives the rotating shaft 12 to rotate, and the second guide plate 13 rotates to buffer the torrent and then discharges it through the drainage trough 11, and the other part of the torrent enters the U-shaped pipe 10, and part of the torrent is buffered by the U-shaped pipe 10, and finally discharged through the drainage trough 11, thereby realizing that the energy dissipation device at the outlet of the spillway of the silt dam can efficiently dissipate energy of the torrent.
[0026] Reference Figure 1-3 The filter assembly includes an installation groove 3, a coarse filter screen 4 and a handle 5. The installation groove 3 is evenly arranged in the flood discharge pipe 2. The coarse filter screen 4 is slidably connected to the inner side of the installation groove 3. The handle 5 is fixedly connected to the upper part of the coarse filter screen 4. The filter holes of the coarse filter screen 4 are staggered to buffer the flood flow while filtering.
[0027] When the coarse filter screen 4 needs to be replaced, the handle 5 is pulled so that the handle 5 drives the coarse filter screen 4 to slide out of the installation groove 3, thereby realizing that the energy dissipation device at the outlet of the silt dam spillway is convenient for replacing the coarse filter screen 4 and improving the service life of the energy dissipation device at the outlet of the silt dam spillway.
[0028] Working principle: When it is necessary to dissipate the energy of the flood at the outlet of the silt dam spillway, the debris in the flood is filtered through the coarse filter 4, and the filtered flood enters the outer shell 1 through the flood discharge pipe 2. The flood pushes the S-shaped guide plate 7 so that the S-shaped guide plate 7 drives the rotating rod 6 to rotate, and the flood is buffered by the rotation of the S-shaped guide plate 7. After being filtered by the fine filter 8, the flood enters the drainage box 9, and part of the flood pushes the second guide plate 13 so that the second guide plate 13 drives the rotating shaft 12 to rotate, and the second guide plate 13 rotates to buffer the flood. After buffering, it is discharged through the drainage trough 11, and the other part of the flood enters the U-shaped pipe 10, and part of the flood is buffered by the U-shaped pipe 10, and finally discharged through the drainage trough 11, thereby realizing that the energy dissipation device at the outlet of the silt dam spillway can efficiently dissipate energy of the flood, and when the coarse filter screen 4 needs to be replaced, the handle 5 is pulled so that the handle 5 drives the coarse filter screen 4 to slide out of the installation groove 3, thereby realizing that the energy dissipation device at the outlet of the silt dam spillway is convenient for replacing the coarse filter screen 4, thereby improving the service life of the energy dissipation device at the outlet of the silt dam spillway.
