Description

A reflector for ultrasonic water meter pipe sections Technical Field

[0001] This utility model relates to the field of ultrasonic water meters, and in particular to a reflective sheet for ultrasonic water meter pipe sections. Background Technology

[0002] An ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water, analyzes and processes the data to determine the water flow rate, and then calculates the water flow rate.

[0003] In existing technologies, the design of ultrasonic water meter pipe sections primarily focuses on measurement accuracy and stability. The reflector, as a crucial component of the ultrasonic water meter pipe section, is vitally important for ensuring accurate ultrasonic wave reflection and precise measurement results. However, traditional reflector designs are typically complex. As shown in Figure 1, the reflector is mounted on a rectangular support, resulting in a large structure. This not only increases material costs but may also obstruct water flow, affecting the water meter's measurement performance. Therefore, simplifying the reflector structure, reducing material costs, minimizing impact on water flow, and improving measurement accuracy have become pressing issues in the design of ultrasonic water meter pipe sections. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a reflective sheet for ultrasonic water meter pipe sections.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] An ultrasonic water meter pipe section reflector is formed by cutting and bending a stainless steel sheet. After cutting, the stainless steel sheet includes a base, a connecting part, and a reflector, wherein the connecting part connects the base and the reflector.

[0007] When the stainless steel sheet is bent, it is bent along the connecting part, and the reflective part is bent towards the base. After bending, the reflective part is inclined relative to the base. In use, the reflective part is aligned with the mounting holes of the ultrasonic transmitter and ultrasonic receiver of the ultrasonic water meter pipe section.

[0008] The base is square in shape.

[0009] The connecting part is in the shape of a thin strip.

[0010] The reflective part is elliptical in shape.

[0011] When in use, the reflector of the ultrasonic water meter pipe section is adapted to the slide rails on both sides inside the ultrasonic water meter pipe section, and slides through the base and slide rails to the position below the mounting holes of the ultrasonic transmitter and ultrasonic receiver in the ultrasonic water meter pipe section.

[0012] The beneficial effects of this utility model are as follows: The reflector is formed by cutting and bending a stainless steel sheet, and consists of only three parts: a base, a connecting part, and a reflective part. Compared with the complex structure of traditional reflectors mounted on similar rectangular brackets, this greatly simplifies the design of the reflector, reduces the amount of material used, and thus effectively reduces material costs. Traditional reflectors are relatively large and easily obstruct water flow. In contrast, the reflector of this utility model has a compact structure: the base is square, the connecting part is thin, and the reflective part is elliptical. The overall size is small, occupying little space within the water meter pipe section, which significantly reduces the obstruction to water flow, ensuring smooth water flow and thus improving the measurement accuracy and stability of the ultrasonic water meter. The reflector base is compatible with the sliding tracks on both sides inside the ultrasonic water meter pipe section, and can be easily installed below the mounting holes of the ultrasonic transmitter and receiver by sliding. The installation process is simple and convenient, ensuring that the reflective part is accurately aligned with the mounting holes of the ultrasonic transmitter and receiver, ensuring effective reflection of the ultrasonic signal, and further improving the accuracy of the measurement results.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0018] An ultrasonic water meter pipe section reflector is formed by cutting and bending a stainless steel sheet 1. After cutting, the stainless steel sheet includes a base 2, a connecting part 3 and a reflector 4, wherein the connecting part 3 is connected between the base 2 and the reflector 4.

[0019] When the stainless steel sheet 1 is bent, it is bent along the connecting part 3, and the reflective part 4 is bent towards the base 2. After bending, the reflective part 4 is inclined relative to the base 2. In use, the reflective part 3 is aligned with the mounting holes 5 of the ultrasonic transmitter and ultrasonic receiver of the ultrasonic water meter pipe section.

[0020] The base 2 is square in shape.

[0021] The connecting part 3 is in the shape of a thin strip.

[0022] The reflective part 4 is elliptical in shape.

[0023] When the reflector sheet for the ultrasonic water meter pipe section is in use, its base 2 is adapted to the slide rails 6 on both sides inside the ultrasonic water meter pipe section, and slides through the base 2 and slide rails 6 to the position below the mounting holes 5 of the ultrasonic transmitter and ultrasonic receiver in the ultrasonic water meter pipe section.

[0024] The implementation principle of this utility model: The reflector sheet 1 for the ultrasonic water meter pipe section of this utility model is integrally formed from a stainless steel sheet through a cutting and bending process. The cut stainless steel sheet 1 includes three parts: a base 2, a connecting part 3, and a reflector 4. The connecting part 3 is located between the base 2 and the reflector 4, serving as a bridge connecting the two. During the bending operation, the reflector 4 is bent towards the base 2 along the bending line using the connecting part 3 as the bending line. After bending, the reflector 4 is inclined relative to the base 2. This inclined structural layout provides structural support for the efficient reflection of subsequent ultrasonic signals. In this utility model, the base 2 of the reflector sheet is square, perfectly matching the internal structure of the ultrasonic water meter pipe section; the connecting part 3 is a slender strip, which becomes arc-shaped after bending, greatly reducing space occupation; the reflector 4 is a smooth ellipse, increasing the reflection area for ultrasonic signal reflection and ensuring efficient signal reflection. This compact and rational structural design significantly reduces the overall size of the reflector, drastically reducing the space it occupies within the water meter pipe section. This effectively minimizes obstruction to water flow, ensuring unimpeded and smooth passage without compromising the reflector's efficient reflection of ultrasonic signals. During installation, the reflector offers convenient and precise installation. The base 2 matches the specifications of the slide rails 6 on both sides of the ultrasonic water meter pipe section. Installers simply slide the reflector to a position directly below the ultrasonic transmitter and receiver mounting holes 5. This sliding installation method is simple to operate, requiring no complex tools or cumbersome steps, and accurately ensures the alignment of the reflector 4 with the ultrasonic transmitter and receiver mounting holes 5. When the ultrasonic signal is emitted to the reflector 4, it is efficiently reflected back, significantly improving the accuracy of the measurement results and ensuring the reliability and stability of the ultrasonic water meter's measurement performance.
