Embodiment two
The embodiment of the present invention is the leak stop with ultrasonic wave, and the protector structure is identical as above-described embodiment one.
Unlike the embodiments above, the reflecting plate 12 of the present embodiment is cut to integrated arc sheetmetal using multistage,
So that supersonic detector can obtain more comprehensive and accurate flow value when detecting.
It please refers to shown in Fig. 5, is the structural schematic diagram of reflecting plate side described in the present embodiment, the reflecting plate 12 includes
Ab sections, bc sections and three sections of cd section, wherein ab sections of selection arc convex, bc sections of selection arc-shaped recess, cd sections of selection straight lines, to
By ultrasonic wave be divided into three sections respectively reflect and receive, in pipeline specific flow and water do not detect.
The present embodiment has used identical structure compared with above-described embodiment at any time, but due to using on reflecting plate 12
Metal plate of different shapes makes ultrasonic wave reflex to another supersonic detector in three kinds of different forms and receives, makes to detect
Panel comprehensively detects pipeline by the comparison and analysis to a variety of ultrasonic waves, completion, improves the leakage with ultrasonic wave
The detection accuracy of water gauge.
Further, the reflecting plate is equipped with the sheet metal of at least three sections and integrally connected, each segment length on sheet metal
It is different with angle, in this way, the ultrasonic wave of diverging can be built up and it is quasi- when reflecting plate reflects ultrasonic wave
It really reflexes on another reflecting plate, so as to improve the detection accuracy of supersonic detector.
In particular, the shape of the described reflecting plate ab sections approximate circular arcs using protrusion, in such manner, it is possible to keep it steady with protection shell
Affixed touching will not be occurred shake by water currents and lead to deviation occur when measurement；Simultaneously as ab sections are located at ultrasonic scatterer
The position dispersed the most can effectively be excluded by ultrasonic reflections and by extra sound wave by using the circular arc of protrusion.
In particular, it is described reflecting plate bc sections using recess approximate circular arc shape, due to bc section positioned at ultrasonic scatterer compared with
It therefore can be effectively by the ultrasonic reflections of accumulation to same direction, so as to improve inspection using recess circular arc for the position of concentration
Survey precision.
In particular, described reflecting plate cd sections use rectilinear form, since cd section positioned at the more dispersed positions of ultrasonic scatterer,
Therefore, it is more directly reflexed to using the metal plate of rectilinear form on the sheet metal of another reflecting plate；Meanwhile cd sections can also be with
Ab sections and bc sections compare, by comparing and analyzing to multiple data measured, to obtain more accurate real-time flow data.
In particular, due to being equipped with multistage shape in the reflecting plate, in this way, when detecting water flow, moreover it is possible to pass through ultrasonic wave
The different principle of transmission speed and the flow value of each section of detection examine the specific water level in pipeline under different medium
Survey, and further judge pipeline whether leak.
Further, the length of each section of arc and the determination method of angle are as follows in the reflecting plate 12:
Step 1: it is determined by cross section curve shape of the formula (1) to ab sections of sheet metals:
Wherein L1For the arc length of ab sections of sheet metals, r is the internal diameter of protective conduit, θ1For ab sections of sheet metals and water (flow) direction
Angle, and:
Wherein, ρ is the actual density of water in pipeline, can be measured by supersonic detector, ρ0For the standard density of water, θ0
For the default angle and θ of reflecting plate0=45 °；
The shape of the ab sections of approximate circular arcs using protrusion can be effectively right while sheet metal is stabilized in reflecting plate
The ultrasonic wave of dispersion is reflected, and is reflexed to assigned direction.
Step 2: it is determined by cross section curve shape of the formula (3) to bc sections of sheet metals:
Wherein, L2For the arc length of bc sections of sheet metals, length of the D between two reflecting plate, θ2For bc sections of sheet metals and water
The angle in direction is flowed, and:
Wherein, ρ is the actual density of water in pipeline, ρ0For the standard density of water；
The shape of the bc sections of spun gold circular arcs using recess, is reflected the ultrasonic wave of aggregation and is made its dispersion, make to reflect
Ultrasonic wave afterwards can parallel launch to another reflecting plate.
Step 3: it is determined by cross section curve shape of the formula (5) to cd sections of sheet metals:
Wherein, L3For the arc length of cd sections of sheet metals, θ3For the angle of cd sections of sheet metals and water (flow) direction, and:
Cd sections of selection rectilinear forms, can will be in relatively stable ultrasonic reflections to another reflecting plate, while it is anti-
The data that data when penetrating ultrasonic wave can be used for when reflecting ultrasonic wave with ab sections and bc sections compare, with this in pipeline whether
More accurate judgement is made in leak.
Each section of shape of sheet metal in reflecting plate 12 is determined by using above-mentioned formula, reflecting plate 12 can be made with most
High efficiency in pipeline water flow and water level detect.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
