At present, irrigation district can measure irrigation canals and ditches flow measuring equipment it is less, and precision is poor, of high cost, Wu Faman Sufficient metering requirements.
Utility model content
The purpose of the utility model is to overcome measurement accuracy existing in the prior art is poor, it is of high cost the defects of, and provide one Kind of high certainty of measurement, construction cost and the relatively low ultrasonic open channel flowmeter of use cost.
Technical solution is used by the utility model solves its technical problem:
A kind of ultrasonic open channel flowmeter, it is characterised in that including:Square frame and the use being fixed on above square frame To measure the ultrasonic probe of height of water level;It is mounted on ultrasonic transducer on four columns of the square frame, and on The ultrasonic transducer of trip and the ultrasonic transducer diagonally opposing corner in downstream are oppositely arranged, two be oppositely arranged ultrasonic transducer Respectively as transmitter and receiver;The ultrasonic open channel flowmeter further includes and the ultrasonic transducer and the ultrasound The control cabinet that ripple probe is electrically connected.
Further, three ultrasonic transducers are installed on the every column.
Further, three ultrasonic transducers in each column be separately mounted to the stem height 1/4, At 1/2 and 3/4.
Further, the column is triangular prism, has transducer mounting surface, and the transducing of the column of two diagonal settings Device mounting surface is parallel to each other.
Further, the control cabinet includes circuit board and wireless transport module, and the circuit board believes the ultrasound of measurement Number and height of water level signal carry out calculating and be converted to data on flows, and be transferred to by wireless transport module in data acquisition The heart.
Further, the control cabinet further includes the display panel for showing data on flows.
Further, the flowmeter uses battery powered.
A kind of beneficial effect of ultrasonic open channel flowmeter of the utility model is:
1st, the flow velocity of current is measured by the multipair ultrasonic transducer for being used for launching and receiving ultrasonic wave, by asking for Average value, obtains more accurate flow speed data, and combines ultrasonic probe measurement height of water level, calculates the stream of current in open channel Amount, the ultrasonic open channel flowmeter measuring accuracy of the utility model are high.
2nd, column design is triangular prism, has transducer mounting surface, and the transducer installation of the column of two diagonal settings Face is parallel to each other, and ensure that ultrasonic transducer is easy for installation, and easy to ensure the transmitting terminal and receiving terminal of ultrasonic transducer Face.
3rd, the flow information of detection can be real-time transmitted to the data acquisition center of distal end by wireless module, realize long-range Monitoring.
4th, flowmeter uses battery powered, and the service life of battery is more than 3 years, without in addition setting up alternating current or arrangement Solar power supply apparatus, reduces construction cost and use cost.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of schematic diagram of ultrasonic open channel flowmeter of the utility model
Wherein:1st, square frame, 11, column, 111, transducer mounting surface, 2, ultrasonic probe, 3, ultrasonic transducer, 4th, control cabinet, 5, open channel.
Embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
A kind of specific embodiment of the ultrasonic open channel flowmeter of the utility model as shown in Figure 1, including:Square frame 1 and the ultrasonic probe 2 for being used for measuring height of water level of the top of square frame 1 is fixed on by a stent;Square frame 1 Ultrasonic transducer 3, and the ultrasonic transducer 3 of upstream and the ultrasonic transducer 3 in downstream are mounted on four columns 11 Diagonally opposing corner is oppositely arranged, and two be oppositely arranged ultrasonic transducer 3 is respectively as transmitter and receiver;Ultrasonic wave open channel 5 Flowmeter further includes the control cabinet 4 being electrically connected with ultrasonic transducer 3 and ultrasonic probe 2.
Square frame 1 is suitable for square open channel 5, and square frame 1 has four columns 11, in order to make to stand positioned at diagonal Ultrasonic transducer 3 on column 11 can relative transmission and reception, column 11 is arranged to three corner posts 11, opposite face is mutual The parallel mounting surface as ultrasonic transducer 3, three corner posts 11 can be made by welding one block of steel plate at the edge of angle-steel.
Multiple ultrasonic transducers 3 can be set in each column 11 as needed, in the present embodiment in each column 11 Three ultrasonic transducers 3 are installed, three ultrasonic transducers 3 are separately mounted to 1/4,1/2 and the 3/4 of 11 height of column Place.Square frame 1 is placed in open channel 5, current upstream and downstream should all ultrasonic transducer 3 transmitting terminal, i.e., it is super The transmitting terminal and receiving terminal of acoustic wave transducer 3 are arranged alternately, and ensure that the ultrasonic wave of multipair transaudient wave transducer is existing along current What direction was propagated, and have what is propagated against water (flow) direction, COMPREHENSIVE CALCULATING draws the speed and flow of current.
