Abstract
The utility model provides an integrated multi-channel ultrasonic sensor measuring device. The integrated multi-channel ultrasonic sensor measuring device comprises a positioning device, measuring rod bodies and ultrasonic sensors, wherein one ultrasonic sensor or a plurality of ultrasonic sensors are/is longitudinally embedded in each measuring rod body, the measuring rod bodies are inserted in the positioning device and are fixed through screws, and the number of the measuring rod bodies is two. The integrated multi-channel ultrasonic sensor measuring device is particularly suitable for multi-channel ultrasonic measurement of open channels, covered channels and culverts, and brings convenience to installation, debugging, repairing and maintenance with water.
Description
Technical field
The utility model belongs to ultrasound wave time difference method and phase difference method and Doppler method flow rate detection technique field, particularly a kind of integrated many group sound channel ultrasonic sensor measuring apparatus.
Background technology
Usually traditional ultrasonic flow-velocity flow measuring sensor all divides into groups to carry out, measure when particularly needing to be with water to carry out Installation and Debugging carrying out multichannel, sound channel is more, and Installation and Debugging work is more complicated even to finishing at last, work difficulty is very high, extremely affects work efficiency.In addition, more and more to the requirement of water conservancy environmental protection canal survey along with the demand of urban construction and development, existing supersonic flow speed flow sensor design is can not satisfy open channel, closed conduit, the hyperacoustic measurement demand of the multichannels such as culvert.
The utility model content
The purpose of this utility model is effectively to have overcome an above-mentioned difficult problem, solve the hyperacoustic flow rate of multichannel and measure problem, practicality, accuracy, the stability of its measurement are improved a lot than traditional metering system, a kind of integrated many group sound channel ultrasonic sensor measuring apparatus are provided.
The technical solution of the utility model is as follows: a kind of integrated multichannel ultrasonic sensor measuring apparatus, comprise locating device, measure the body of rod, ultrasonic sensing device, vertically embed one or more excusing from death wave sensors on the described measurement body of rod, the described measurement body of rod inserts in the locating device and by screw and fixes, and the described measurement body of rod is two.
Further, the described measurement body of rod is anticorrosion material, and the described measurement body of rod is circular or streamlined.
Further, described ultrasonic sensing device and the measurement body of rod adopt mechanical fasteners and chemical adhesion sealing.
The beneficial effects of the utility model are: efficiently solve when carrying out the multichannel ultrasonic measurement, the grouping installation of sensors is inconvenient, inaccurate, is difficult for the large problem of debugging maintenance error, has installation quick and precisely, the characteristics that the ratio of performance to price is high, debugging is easy to use; This device is particularly suitable for open channel, closed conduit, and the multichannel ultrasonic measurement of culvert can be with water to install, debugging, maintenance maintenance easily.

Wherein: 1, measure the body of rod, 2, the ultrasonic sensing device.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made brief description.
As shown in Figure 1, a kind of integrated multichannel ultrasonic sensor measuring apparatus, comprise locating device, measure the body of rod 1, ultrasonic sensing device 2, measure and vertically embed one or more excusing from death wave sensors 2 on the body of rod 1, measure in the body of rod 1 insertion locating device and by screw and fix, measuring the body of rod 1 is two.Measuring the body of rod 1 is anticorrosion material, and the described measurement body of rod 1 is circular or streamlined, is conducive to water flow stationary and twines by preventing impurity.。Ultrasonic sensor 2 and the measurement body of rod 1 adopt mechanical fasteners and chemical adhesion sealing.
The direction of ultrasonic sensor 2 can be adjusted as required, and the distance of a plurality of ultrasonic sensors 2 can be adjusted arbitrarily as required, and the frequency diameter of ultrasonic sensor 2 can be adjusted as required.
Determine according to the actual requirements type diameter and the quantity of ultrasonic sensor, determine to measure the body of rod 1 diameter length, organize ultrasonic sensor 2 rigging error on the measurement body of rod 1 more and can guarantee measuring accuracy less than 0.5mm.When integrated multichannel ultrasonic sensor was installed, locating device got final product than measuring the large 1mm of the body of rod 1 diameter, and the error of perpendicularity is less than 2% of the sounding rod body length.
Adopt as shown in Figure 2 ultrasound wave time difference method Z method to measure.
Adopt as shown in Figure 3 ultrasound wave time difference method V method to measure.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
