Description
Technical field
This utility model is related to a kind of supersonic Doppler current meter.
Background technology
Twentieth century nineties, China introduces and tries out acoustic Doppler class fluid velocity profile instrument and carries out entrance of Changjiang River tidal current
Measurement is tested, and has started the beginning that domestic application acoustic Doppler quasi-instrument carries out discharge of river test.Survey due to this quasi-instrument
The more conventional instrument of stream method is compared, and has easy to operate, and test lasts short, and the scope that tests the speed is big, can obtain test number in real time
According to the features such as realize online flow measurement, having obtained testting the consistent accreditation of worker.Doppler's flow velocity flow instrument is in China
Range progressively expands, and the species of use has Doppler's point current meter, fixed Doppler's flow velocity section plotter, boating type many
General Le fluid velocity profile instrument etc..With a large amount of introductions applications of acoustic Doppler quasi-instrument water conservancy and marine systems at home, have by
Gradually become China's river discharge test and the trend of water consumption measurement main flow instrument.China is vast in territory, and river conditions thousand differ from ten thousand
Not, measurement non-stationary flow and the flow by tidal effect are the technical barriers of hydrologic survey, when changeable fluidised form is also to flow measurement
Between, flow measurement means, flow measurement mode and survey crew propose higher technical requirements.But, current acoustic Doppler's quasi-instrument
Use condition still have certain limitation, the bed load in river, sediment charge, floating thing etc. all can be made to flow measurement
Become certain impact.At present, China not yet makes the vertification regulation of acoustic Doppler quasi-instrument, and this quasi-instrument is as metering
Instrument, in Experiment in Introduction with during promoting the use of, the measurement verification also not over domestic any quality inspection organization all the time,
This does not meet China《Metric method》The requirement that gauge check utensil is used, due to there is no legal effective calibrating of quality inspection organization,
The accuracy of instrument and reliability cannot be verified, so cause the data accuracy that instrument is measured just to lack legal effective
Technical support and science tracing basis.Existing supersonic Doppler current meter display interface complexity, complex operation, output
Mode is single, and wiring is loaded down with trivial details, power supply inconvenience.
In view of above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of supersonic Doppler stream
Fast instrument is so as to more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of supersonic Doppler current meter.
Supersonic Doppler current meter of the present utility model, including upper shell, connects housing and lower house, described upper shell
Pass through hydropneumatic O shape rubber seal rings for seal with described connection housing, be provided with cable in the middle part of upper shell, described cable
Line seals through in the middle part of cable seal external member and upper shell, is provided with mainboard in the inside connecting housing, described mainboard is through cross slotted disk
Head screw is fixedly connected with circuit board mounting base, is provided with pressure transducer, at the end of described lower house in described lower casing body
Portion is provided with ultrasonic sensor.
Further, described hydropneumatic is set to fluorubber with O shape rubber seal.
Further, described hydropneumatic is 58*1.8 centimetre of φ with the size of O shape rubber seal.
By such scheme, this utility model at least has advantages below：The ultrasound wave of supersonic Doppler current meter passes
Sensor has two transducers, an emission sensor, a reception sensor, and the frequency that reception sensor receives can be higher than to send out
The frequency penetrated is adverse current, and receiving the frequency that receives of sensor can be following current less than the frequency of transmitting, specifically pass through hardware and
Computed in software goes out flow rate of water flow and water (flow) direction, and supersonic Doppler current meter has two kinds of master systems, and one is GPRS number
According to transmission, wireless upload has broken away from lengthy and jumbled cable puzzlement, and the broad covered area being wirelessly transferred, is cell-phone number, only mobile phone
Transmission of wireless signals can be realized in the place having signal, simply telecommunications, UNICOM, cell phone number, and client only needs to buy one
Individual common Mobile phone card just can be realized being wirelessly transferred, and then pass through background system, the monitor in real time of achievable data, have oneself
Data base, achievable data last inquiry.Another kind of master system is the locally displayed of data, and data display is more straight
See, host service function friendly interface, setting aspect, flow velocity, numerical digit, temperature can be realized according to live actual channel come arrange parameter
The monitoring of degree, after setting channel type and parameter, can also calculate outflow, and realizes on the digital quantity of instantaneous delivery
Pass, realize locally displayed and remote transmission.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can be practiced according to the content of description, after being described in detail such as with preferred embodiment of the present utility model below.
