Under let out ecological flow situation, can in the future work and policy-making scheme accurate foundation is provided, be guarantee region in ecology
Flow provides strong foundation, while the monitoring of flow also provides foundation to the gate switching action in power station.Existing ecological flow
Amount monitoring is usually to be collected to data on flows using flow sensor, using wireless transmission method by collected live number
According to monitoring center is transferred to, monitoring center on time, summarizes collected data according to quantity, and passes through data analysis and guidance lock
Door opening and closing operations.
Flow sensor, is usually installed on riverbed, in order to prevent water impact by existing ecological flow monitoring system
The installation site for changing sensor, is usually provided with a pedestal in sensor base, if having mud, rubbish etc. heavy in river
Product object is then mounted on sensor on the side of deposit, or in sensor with doing an erecting bed between river, for raising
Installation site.
However existing ecological flow monitoring system, it is that directly flow sensor is directly mounted on riverbed, due to river
Flow under interior different depth is not the same, and flow sensor, which is directly directly mounted at the mode on riverbed, will cause installation
Position is limited, and there are bigger difficulty for the traffic monitoring under different depth.In addition, the impurity that water flow is carried secretly in river, sludge, rubbish
Rubbish etc. is gradually accumulated, and be will lead to the mud to be formed and is flooded flow sensor, and flow sensor incudes less than water flow, causes to flow
Quantity sensor failure；Further, since sensor is covered by mud, it is be easy to cause sensor degradation, reduces sensor life-time.
Utility model content
