Embodiment two

The embodiment of the present invention is the reflection bracket based on ultrasonic wave leak water detdction, the reflection supporting structure and above-described embodiment One is identical.

Arc unlike the embodiments above, that reflector plate uses multistage and is integrated in the reflecting plate 1 of the present embodiment Metal plate, so that ultrasound examination machine can obtain more comprehensive and accurate flow value when detecting.

It please refers to shown in Fig. 2, is the structural schematic diagram of reflector plate side described in the present embodiment, the reflector plate includes ab Section, 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 incite somebody to action Ultrasonic wave be divided into three sections respectively reflect and receive, in pipeline specific flow and water do not detect.

The present embodiment is compared with above-described embodiment, though identical structure is used, due in reflecting plate 1 on reflector plate Metal plate of different shapes has been used, ultrasonic wave is made to reflex to ultrasonic probe in three kinds of different forms and has been received, ultrasound is made Wave detection machine records the transmission time of ultrasonic wave, and completion comprehensively detects pipeline, improves the ultrasonic water Manage the detection accuracy of micro- leakage monitoring device.

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 ultrasound examination machine.

In particular, the shape of the described reflector 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 wave dispersion The position dispersed the most is penetrated, can effectively be excluded by ultrasonic reflections and by extra sound wave by using the circular arc of protrusion.

In particular, it is described reflector 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 reflector 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 1；Meanwhile cd sections may be used also It compares with ab sections and bc sections, by being compared and analyzed to multiple data measured, to obtain more accurate real-time traffic Value.

In particular, due to being equipped with multistage shape in the reflecting plate 1, 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 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 1:

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 pipeline, θ₁For the angle of ab sections of sheet metals and water (flow) direction, And:

Wherein, ρ is the actual density of water in pipeline, can be measured by ultrasound examination machine, ρ₀For the standard density of water, θ₀For 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 1, θ₂For bc sections of sheet metals with The angle of water (flow) direction, 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 1 is determined by using above-mentioned formula, reflecting plate 1 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 the technical solution of the utility model, still, this Field technical staff is it is easily understood that the protection scope of the utility model is expressly not limited to these specific embodiments.In Under the premise of the principles of the present invention, those skilled in the art can make equivalent change to the relevant technologies feature Or replacement, the technical solution after these changes or replacement are fallen within the protection scope of the utility model.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model；For this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
