Description
Technical field
It the utility model is related to a kind of hydraulic structure flow detection voltage stabilizing pressure-measuring pipe.
Background technology
In recent years, the fast-developing of social economy requires more and more higher to flood control and disaster reduction, the management requirement to flood control works
Also more and more higher.In general current pressure instrumentataion is only applicable to the detection under hydrostatic condition, for the water source of flowing, due to by
The impact of dynamic current influences, larger to pressure instrumentataion interference, and the data measured are not accurate enough.
At present, water conservancy administration department is difficult to monitor waterwork logistics capacity in real time, and used monitoring device is still
Preferable monitoring effect can not be played so that flood control items control measure can not effectively be implemented.Therefore, it is necessary in prior art basis
On, a kind of stable performance is developed, the facility for being easy to use flow to monitor in real time again.
The content of the invention
In order to solve defect present in above-mentioned prior art, the utility model provides a kind of waterwork logistics capacity inspection
Voltage stabilizing pressure-measuring pipe is used in survey, and the pressure-measuring pipe stability is good, and data are accurate, easy to operate.
The technical solution adopted in the utility model：A kind of hydraulic structure flow detection voltage stabilizing pressure-measuring pipe, including outside
Sleeve pipe and the inner sleeve being fixed on outer sleeve inwall；It is provided with outer sleeve and the inner sleeve periphery uniform
Permeable hole；Pressure sensor is fixed with the inner sleeve.
Preferably, the outer sleeve and inner sleeve are coating steel pipes.
Preferably, outer sleeve and the inner sleeve diameter parallel.
Preferably, a diameter of 50mm of the inner sleeve；A diameter of 100cm~150cm of the outer sleeve.
Preferably, the diameter of the permeable hole is 8mm, and longitudinal hole is away from being 100mm.
Preferably, the diametric(al) face current center line direction arrangement of the outer sleeve, inner sleeve are built close to water conservancy project
Build thing side；The pressure sensor is fixed on the bottom of inner sleeve.
The utility model beneficial effect：1. using waterpower principle, pressure-measuring pipe position is current stationary point, is easy to measure to dynamic
Head pressure, calculated accurately using empirical equation than tradition.
2. two sleeve pipes inside and outside pressure-measuring pipe, current are seeped into inner tube through outer tube, reduce ripples influence, pressure head
It is highly stable.
3. apparatus structure is simple, installation or replacing part are convenient and swift, will not silting.
4. engineering operation is not influenceed, and construction cost is cheap.
