Example two
The embodiment of the utility model provides an ultrasonic water meter, this water gauge structure is the same with above-mentioned embodiment one.
Different from the above embodiments, the reflector plate 31 of the present embodiment uses a multi-segment and integrated arc-shaped metal plate as the reflector plate, so that the ultrasonic detector can obtain a more comprehensive and accurate flow value during detection.
Please refer to fig. 3, which is a schematic structural diagram of a side surface of the reflection sheet according to the present embodiment, the reflection sheet includes three sections, namely, an ab section, a bc section and a cd section, wherein the ab section is an arc-shaped protrusion, the bc section is an arc-shaped recess, and the cd section is a straight line, so as to divide the ultrasonic wave into three sections for respectively reflecting and receiving, so as to detect the specific flow rate and water in the pipeline.
Compared with the above embodiments, the present embodiment uses the same structure at any time, but because the metal plates with different shapes are used on the reflection sheet in the reflection plate 31, the ultrasonic waves are reflected to the ultrasonic receiving probe 22 and received in three different forms, so that the ultrasonic flow detector records the transmission time of the ultrasonic waves, the comprehensive detection of the pipeline is completed, and the detection precision of the ultrasonic water meter is improved.
Furthermore, the reflecting plate is provided with at least three sections of metal sheets which are integrally connected, and the length and the angle of each section of metal sheet are different, so that when the reflecting plate reflects the ultrasonic wave, the diffused ultrasonic wave can be accumulated and accurately reflected to the other reflecting plate, and the detection precision of the ultrasonic detector is improved.
Particularly, the ab section of the reflector plate is in a convex approximate arc shape, so that the reflector plate can be stably contacted with the protective shell, and the measurement deviation caused by shaking due to the influence of water flow can be avoided; meanwhile, since the ab-section is located at a position where ultrasonic scattering is most dispersed, ultrasonic waves can be effectively reflected and unnecessary sound waves can be removed by using the convex arc.
Particularly, the reflector plate bc section is in a shape of a concave approximate arc, and the bc section is located at a position where ultrasonic scattering is concentrated, so that the accumulated ultrasonic can be effectively reflected to the same direction by adopting the concave arc, and the detection precision is improved.
Particularly, the cd section of the reflector plate is linear, and because the cd section is located at a position where ultrasonic scattering is relatively dispersed, the metal plate adopting the linear shape is more directly reflected onto the metal plate of the other reflector plate 31; meanwhile, the cd section can be compared with the ab section and the bc section, and a more accurate real-time flow value can be obtained by comparing and analyzing a plurality of measured data.
Particularly, since the reflecting plate 31 has a multi-stage shape, when detecting water flow, the specific water level in the pipeline can be detected according to the principle that the transmission speed of ultrasonic waves is different under different media and the flow value detected by each stage, and whether the pipeline leaks water can be judged.
Further, the method for determining the length and angle of each arc in the reflective plate 31 is as follows:
step 1: the section curve shape of the ab-section metal sheet is determined by the formula (1):
wherein L is1Is the arc length of the ab-segment metal sheet, r is the inner diameter of the pipe, theta1Is the contained angle of ab section sheetmetal and rivers direction, just:
wherein rho is the actual density of water in the pipeline and can be measured by an ultrasonic detector, and rho0Is the standard density of water, theta0Is a predetermined angle theta of the reflecting plate0＝45°；
The ab section adopts the shape of convex approximate circular arc, when stabilizing the sheetmetal at the reflecting plate, can effectively reflect dispersed ultrasonic wave to with its reflection to the specified direction.
Step 2: the shape of the cross-sectional curve of the bc-segment metal sheet is determined by equation (3):
wherein L is2Is the arc length of the bc-segment metal sheet, D is the length between the two reflecting plates 31, theta2Is the included angle between the bc section metal sheet and the water flow direction, and:
wherein rho is water in the pipelineActual density of (p)0Is the standard density of water;
the bc section adopts a shape of a concave gold wire arc, reflects the collected ultrasonic waves and disperses the ultrasonic waves, so that the reflected ultrasonic waves can be emitted to the other reflecting plate in parallel.
And step 3: the sectional curve shape of the cd segment metal sheet is determined by equation (5):
wherein L is3Arc length of cd segment metal piece, theta3Is an included angle between the cd section metal sheet and the water flow direction, and is as follows:
the cd section chooses the straight line shape for use, can reflect the ultrasonic wave steady relatively to another reflecting plate on, its data when the reflection ultrasonic wave can be used for contrasting with the data when ab section and bc section reflection ultrasonic wave simultaneously to this whether leaks in the pipeline and makes more accurate judgement.
