Incomplete transparent bottom plate shrinking type energy dissipater and energy dissipating method
An energy-dissipating and incomplete technology, applied in water conservancy projects, marine engineering, coastline protection, etc., can solve problems such as uneven distribution along the longitudinal and lateral directions, enhanced turbulence and air aeration, and aggravated flood discharge and atomization. Flood discharge atomization intensity and influence range, eliminating water fin phenomenon, reducing impact pressure effect

Embodiment 1
[0023] A non-completely air-permeable base plate retractable energy dissipator, such as image 3 As shown, it is arranged on the dam body 4 of the dam. The energy dissipator includes a bottom plate 1 and side walls 2 arranged on two opposite sides on the bottom plate 1. The two side walls 2 on the side of the discharge hole of the energy dissipator are symmetrically narrowed and The contraction section 3 is formed, and the energy dissipator also includes a support plate 5 arranged at the bottom of the drain hole and integrated with the bottom plate 1. The support plate 5 forms a broken-line non-permeable hollow shape to eliminate the lower edge of the drain tongue. water fins.
[0024] In the actual application process of the present invention, in the direction close to the lower side of the base plate, when the angle between the support plate and the base plate is 6-9° / the support plate is 1 / 6-1 / 5 of the total length of the contraction section , the supporting plate 5 consti...
Embodiment 2
[0030] A non-completely air-permeable base plate retractable energy dissipator, such as Figure 4 As shown, it is arranged on the dam body 4 of the dam. The energy dissipator includes a bottom plate 1 and side walls 2 arranged on two opposite sides on the bottom plate 1. The two side walls 2 on the side of the discharge hole of the energy dissipator are symmetrically narrowed and The contraction section 3 is formed, and the energy dissipator also includes a support plate 5 arranged at the bottom of the drain hole and integrated with the bottom plate 1. The support plate 5 forms a broken-line non-permeable hollow shape to eliminate the lower edge of the drain tongue. water fins.
[0031] In the actual application process of the present invention, in the direction close to the lower side of the base plate, when the angle between the support plate and the base plate is 6-9° / the support plate is 1 / 6-1 / 5 of the total length of the contraction section , the supporting plate 5 const...
