Background technology
Stilling pool slab is also referred to as energy dissipating well, is the facility for reducing water flow dynamic energy.China's water resource is relatively poor and spatial and temporal distributions
It is unbalanced, so regional water transfer and distruting water transregionally just become one of the important channel for solving current distribution of water resources unevenness.
So far, 2 kinds of use of water base of remote conveying mode, channel hydraulic pipeline and pipeline water delivery.Pipeline water delivery has compared to channel hydraulic pipeline
The advantages that economizing the land resource, reducing investment, water quality is kept not to be damaged, therefore pipeline water delivery becomes development trend.But by
In reasons such as landform, landforms, for pipeline during water delivery, local pressure may exceed the range that pipeline can bear, in order to
Ensure that the safety of pipeline, the extra energy in this part must just be eliminated.And stilling pool slab is as a kind of economical and effective energy dissipating side
Formula is often used in Long-distance Pipeline for Water Conveyance engineering.
Invention content

The big pipeline of difference is easy to happen cavitation corrosion and cavitation erosion, the vibration and noise that flow unstability easy tos produce.And there are energy dissipating and
Flow smoothes out conflicting problem.Riverbank can be also protected simultaneously, reduces the expense of bank strengthening.
The technical solution of the utility model is：A kind of novel rolling stilling pool slab device, including water inlet line 1, stilling pool slab
2, steel pipe 3, EVA and compound polyurethane material roller 4, outlet conduit 5；
The stilling pool slab 2 is located at the underface of water inlet line 1, and several steel pipes 3 are lateral and are vertically spaced substantially equidistant shape
It is connected to the both ends of stilling pool slab 2 at the both ends of array-like, and every steel pipe 3, it is equidistant through there is several on every steel pipe 3
EVA and compound polyurethane material roller 4, steel pipe 3, EVA and compound polyurethane material roller 4 are respectively positioned on inside stilling pool slab 2, water outlet
Pipeline 5 is connected to water inlet line 1, stilling pool slab 2, and 5 elevation of outlet conduit is higher than 2 elevation of stilling pool slab.
Preferably, a diameter of 0.3m-0.5m of the EVA and compound polyurethane material roller 4.
Preferably, equidistant through having 3 EVA and compound polyurethane material roller 4 on described every steel pipe 3.
The utility model has the beneficial effects that：It is simple in structure, it is easily operated, it is suitable in the case of high water head, larger flow.
It solves the big pipeline of water drop and is easy to happen cavitation corrosion and cavitation erosion, the vibration and noise that flow unstability easy tos produce.With
And existing energy dissipating and flow smooth out conflicting problem.Riverbank can be also protected simultaneously, reduces the expense of bank strengthening.

Specific implementation mode
With reference to the accompanying drawings and detailed description, the utility model is further described.
Embodiment 1：As shown in Figs. 1-3, a kind of novel rolling stilling pool slab device, including water inlet line 1, stilling pool slab 2, steel
Pipe 3, EVA and compound polyurethane material roller 4, outlet conduit 5；
The stilling pool slab 2 is located at the underface of water inlet line 1, and several steel pipes 3 are lateral and are vertically spaced substantially equidistant shape
It is connected to the both ends of stilling pool slab 2 at the both ends of array-like, and every steel pipe 3, it is equidistant through there is several on every steel pipe 3
EVA and compound polyurethane material roller 4, steel pipe 3, EVA and compound polyurethane material roller 4 are respectively positioned on inside stilling pool slab 2, water outlet
Pipeline 5 is connected to water inlet line 1, stilling pool slab 2, and 5 elevation of outlet conduit is higher than 2 elevation of stilling pool slab.
Anti-scour wall is collectively formed in several steel pipes 3 and several EVA and compound polyurethane material roller 4, when penetrating for ejection
After stream enters stilling pool slab 2, anti-scour wall is first impacted, then contact 2 bottom of stilling pool slab, then spread around.EVA and polyurethane are compound
Material roller 4 makes flow, and mutually blending, mutually collision, rolling rise to consume a large amount of energy in stilling pool slab 2.Disappear simultaneously
In addition to cavitation corrosion and cavitation erosion easily occur for the big pipeline of water drop, eliminate to pipeline and building detrimental effect, protection
Riverbank, reduces the expense of bank strengthening.
Further, the EVA and compound polyurethane material roller 4 can be big according to 2 size of stilling pool slab, injection flow
Small, reasonable Arrangement cylinder sizes and quantity, depending on concrete foundation project scale, the EVA and polyurethane described in the present embodiment are multiple
A diameter of 0.3m-0.5m of condensation material roller 4.
Further, equidistant through having 3 EVA and compound polyurethane material roller 4 on described every steel pipe 3.
It is this high intensity material that EVA and compound polyurethane material roller 4, which use EVA and compound polyurethane material main cause,
Expect inherently high resilience and anticollision is wear-resisting, can be damaged under high speed water jet impact to avoid roller.With resistance to biological aging,
The series of advantages such as mechanical strength is big, good weatherability, oil resistivity are good, and it is moderate.
The operation principle of the utility model is：After the jet stream of ejection enters stilling pool slab 2, anti-scour wall is first impacted, then contact
2 bottom of stilling pool slab, then spreads around.The EVA and compound polyurethane material roller 4 added keeps flow mutual in stilling pool slab
Blending mutually collides, rolling rising.The turbulent fluctuation kinetic energy and turbulent fluctuation dissipative shock wave for making flow increase to consume most of energy.Together
When can effectively reduce stilling pond Gu Bi is washed away, ensure the connection of water flow stationary and downstream line.Weaken pipeline hair significantly
The case where raw cavitation corrosion and cavitation erosion, and to there is a problem of that energy dissipating and flow smooth out conflicting.
The specific embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the utility model is not
It is limited to the above embodiment, within the knowledge of a person skilled in the art, this practicality can also be not being departed from
Various changes can be made under the premise of novel objective.
