On energy dissipating roller 2 form an energy dissipating roller assembly, several energy dissipating roller assemblys from top to bottom, are equidistantly arranged in
Inside vertical shaft, two adjacent energy dissipating roller assemblys are interspersed in cross.
The energy dissipating roller 2 is first connected with stainless steel branch pipe 3, is fixed on stainless steel branch pipe 3, it is ensured that its good rotation
Turn performance；Then energy dissipating roller assembly is installed to the vertical shaft energy dissipating section for presetting detent again, the form of installation is from upper
And it is lower it is equidistant, cross, be horizontally mounted.
Further, the energy dissipating roller 2 is made of compound polyurethane material, and main cause is that the material has resistance to life
Object aging, the series of advantages such as wear-resisting property is good, mechanical strength is big, good weatherability, oil resistivity are good, and it is moderate, so more
Add durable, is hardly damaged.Energy dissipating roller 2 and have good verticity, the energy in water flow is converted into rotation to reach
The purpose of kinetic energy dissipation.
Further, placement of the flow direction entered from top water inlet 1 perpendicular to the top energy dissipating roller assembly
Direction can carry out the energy dissipating of first time to the greatest extent in this way.
Further, the inner wall at the vertical shaft energy dissipating section both ends is equipped with corresponding with to 3 pipe diameter size of stainless steel branch pipe
Detent, the both ends of stainless steel branch pipe 3 are fastened in detent, simple in construction, easy to disassemble and assemble.
Further, the lower part water outlet 4 is arranged on the side wall of vertical shaft lower part, and apart from one spacing of silo bottom
From.Water outlet 4 flow direction in lower part is generally from vertical shaft side to outflow, and outlet port is generally higher than one spacing of silo bottom
From, make the energy dissipating again that sluices in this way, it is steady to flow out.
Further, the shape of the lower part water outlet 4 is gateway opening shape, constructs quick and convenient, can cope with complexity
Regimen.
It further, further include pedestal, vertical shaft is integrally built on pedestal.
Specifically, in the present embodiment: the top water inlet 1 is that radius is 0.5m circle water inlet, gradually by one section
