Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-5 This utility model discloses a composite material ultrasonic water meter pipe section, comprising: a pipe body 1, integrally cast from composite material; one end of the pipe body 1 having an inlet screw 3, and the other end having an outlet screw 5; a reinforcing ring 7 longitudinally fixedly connected to the surface of the pipe body 1 to increase its pressure and impact resistance, and to facilitate the installation of the ultrasonic water meter; a support beam 8 transversely fixedly connected to the surface of the pipe body 1 to protect the pipe body 1 and improve its overall strength; a first acoustic transducer mounting hole 15 and a second acoustic transducer mounting hole 16 on the upper surface of the support beam 8; a trapezoidal cable tray 9 fixedly connected to the upper surface of the support beam 8; a cover plate 12 detachably connected to the upper right side of the trapezoidal cable tray 9 for easy cable routing and subsequent maintenance; and a cover plate 2 detachably connected to the upper left side of the trapezoidal cable tray 9 for easy cable routing and subsequent maintenance.

[0023] The outer surface of the reinforcing ring 7 is provided with ultrasonic water meter docking screw holes 17, and the outer surface of the reinforcing ring 7 is provided with acoustic wave reflector mounting screw holes 18. A sealing ring is provided between the acoustic wave reflector mounting screw holes 18 and the acoustic wave reflector 11. The acoustic wave reflector 11 is detachably connected inside the acoustic wave reflector mounting screw holes 18. The surface of the tube body 1 is horizontally fixedly connected with reinforcing ribs 6, and the outer surface of the tube body 1 is fixedly connected with hexagonal nuts 1-2 and 2-4.

[0024] Hexagonal nut 12 is located on the side of the screw hole 3 at the water inlet end, and the side of hexagonal nut 12 is fixedly connected to one end of the supporting beam 8. Hexagonal nut 24 is located on the side of the screw hole 5 at the water outlet end, and the side of hexagonal nut 24 is fixedly connected to the other end of the supporting beam 8.

[0025] The trapezoidal cable guide 9 has a hollow interior. Its left end is fixedly connected to the side surface of the hexagonal nut 12, and its right end is fixedly connected to the side surface of the hexagonal nut 24. The outer surface of the trapezoidal cable guide 9 has an ultrasonic water meter mounting hole 13 and a water flow direction indicator 10.

[0026] Both the acoustic transducer mounting hole 15 and the acoustic transducer mounting hole 16 have a 45° tilt angle, and are located on both sides of the ultrasonic water meter docking screw hole 17 and are distributed in a mirror image. The acoustic transducer mounting hole 15 passes through the outer wall of the pipe body 1, and the acoustic transducer mounting hole 16 passes through the outer wall of the pipe body 1.

[0027] Working Principle: When the ultrasonic water meter is working, water flows through pipe body 1, enters through the inlet screw port 3, and exits through the outlet screw port 5. Ultrasonic transducers installed in mounting holes 15 and 16 emit ultrasonic signals into the water flow at a certain frequency. Due to the special angle and position design of mounting holes 15 and 16, the ultrasonic waves can effectively propagate in the water flow and are reflected when they encounter the acoustic reflector plate 11. The reflected ultrasonic signal is received by another acoustic transducer. Based on parameters such as the time difference or frequency difference of the ultrasonic waves propagating upstream and downstream in the water flow, combined with known physical parameters such as the pipe inner diameter and the length of the sound channel, a specific algorithm is used to calculate the water velocity. Then, by multiplying the velocity by the cross-sectional area of ​​the pipe, the water flow rate is obtained, achieving accurate measurement of the water flow.

[0028] Meanwhile, the reinforcing ring 7 and the reinforcing rib 6 structural components ensure that the pipe body 1 remains stable under the impact and pressure of water flow, without affecting the propagation of ultrasonic signals and measurement accuracy, thus providing a solid physical basis for the stable operation of the ultrasonic water meter.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
