Example two

The embodiment of the utility model provides a for take leading filterable protection device that leaks, this protection device structure is the same with above-mentioned embodiment one.

Different from the above embodiments, the reflecting plate 52 of the present embodiment uses a plurality of arc-shaped metal plates cut into a whole, so that the ultrasonic detector can obtain a more comprehensive and accurate flow value during detection.

Referring to fig. 7, which is a schematic structural diagram of a side surface of the reflecting plate according to the embodiment, the reflecting plate 52 includes three sections, namely, an upper section, a middle section and a lower section, wherein the upper section is an arc-shaped protrusion, the middle section is an arc-shaped recess, and the lower section is a straight line, so as to divide the ultrasonic waves 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 embodiment, the present embodiment uses the same structure at any time, but uses metal plates with different shapes on the reflection plate 52, so that the ultrasonic waves are reflected to another ultrasonic detector and received in three different forms, the detection panel completes the overall detection of the pipeline by comparing and analyzing a plurality of ultrasonic waves, and the detection precision of the water leakage detector with the ultrasonic waves is improved.

Further, the upper section of the reflecting plate 52 is a convex arc, so that the reflecting plate can be stably contacted with the protective shell 11, and the measuring deviation caused by shaking due to the influence of water flow can be avoided.

In particular, the concave arc is adopted in the middle section of the reflecting plate 52, so that when the reflecting plate reflects ultrasonic waves, the scattered ultrasonic waves can be collected and reflected to the same direction, and the detection precision is improved.

In particular, the lower section of the reflecting plate 52 has a linear shape for comparing with the upper and middle sections, and by comparing and analyzing a plurality of measured data, a more accurate real-time flow value can be obtained.

Particularly, since the reflecting plate 52 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 further judged.

Further, the method for determining the length and angle of each arc in the reflector 52 is as follows:

step 1: the length of the first segment of the reflector is determined by the formula (1):

wherein L is₁Is the arc length of the first segment of reflector plate, r is the inner diameter of the protective pipeline, theta₁Is the included angle of the first section of reflector plate and the water flow direction, and:

wherein rho is the actual density of water in the pipeline, rho₀Is the standard density of water, theta₀Presetting an included angle for the reflecting plate;

step 2: the length of the second segment reflector is determined by equation (3):

wherein L is₂Is the arc length of the second segment of reflector plate, D is the length between the two reflector plates, theta₂Is the included angle between the second section of reflector plate and the water flow direction, and:

wherein rho is the actual density of water in the pipeline, rho₀Is the standard density of water;

and step 3: the length of the third segment reflector is determined by equation (5):

wherein L is₃Is the arc length of the third segment reflector, theta₃Is an included angle between the third section of reflector plate and the water flow direction, and is as follows:

by determining the shape of each segment of the reflector in the reflector 52 using the above formula, the reflector 12 can detect the water flow rate and the water level in the pipeline with the highest efficiency.
