Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic water meters, in particular to a pipe section for an ultrasonic water meter. Background Art

[0002] An ultrasonic water meter is a new type of water meter that analyzes and processes the time difference generated by the change in the speed of ultrasonic waves when propagating in the water in the forward and reverse directions to obtain the water flow velocity and further calculate the water flow rate. It mainly consists of a metering pipe connected and communicated with a fluid conveying pipe and ultrasonic transducers thereon. Two ultrasonic transducers installed symmetrically at the upstream and downstream of the pipe alternately transmit and receive ultrasonic signals. At one moment, the upstream ultrasonic transducer emits an ultrasonic signal, and the downstream ultrasonic transducer receives the ultrasonic signal; at another moment, the downstream ultrasonic transducer emits an ultrasonic signal, and the upstream ultrasonic transducer receives the ultrasonic signal. The flow velocity of the fluid is indirectly measured by measuring the time difference of the ultrasonic wave propagating in the forward or reverse direction in the medium, and the flow rate is indirectly measured by combining the cross-sectional parameters of the pipe.

[0003] For example, Chinese Patent No. CN115493668A discloses a pipe section for an ultrasonic water meter, which includes a measuring pipe made of a metal round pipe, and the reducing diameter method of the measuring pipe is to form the pipe section by extrusion; transducer mounting seat mounting holes are arranged at intervals on the side wall of the measuring pipe, and a transducer mounting seat for installing an ultrasonic transducer is arranged on the transducer mounting seat mounting holes. The transducer mounting seat and the transducer mounting seat mounting holes are laser welded on the measuring pipe. It introduces the signal wire of the transducer from the transducer mounting seat mounting hole to the meter head mounting seat through a wire passing column. Although it can protect the signal wire of the transducer, setting the wire passing column not only increases the complexity of the overall structure of the pipe section, improves the production difficulty, but also has poor aesthetics. Summary of the Utility Model

[0008] As a further improvement of the present utility model, an installation cover is provided at the end of the transducer mounting seat away from the metering pipe section. The installation cover is used to cover the assembly hole, the wire threading hole and the lead wire groove, and the installation cover is detachably connected to the transducer mounting seat.

[0009] As a further improvement of the present utility model, the transducer mounting seat and the installation cover are detachably connected by fasteners.

[0023] The orientation terms such as up, down, left, right, front, back, front side, back side, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

At the same time, a wire passing hole 22 is provided on the transducer mounting seat 2, and a wire passing cavity 23 communicating the wire passing hole 22 with the inside of the meter head mounting structure is formed inside the transducer mounting seat 2. Thus, the signal wire of the transducer can be inserted into the wire passing hole 22, pass through the wire passing cavity 23 inside the transducer mounting seat 2, and then pass out to the inside of the meter head mounting structure. On the one hand, it can avoid the interference of external factors on the signal wire, thereby protecting the signal wire from damage and improving the service life of the transducer.

[0025] At the same time, in order to facilitate the introduction of the signal wire into the inside of the meter head mounting structure, both the assembly hole 21 and the wire passing hole 22 are formed on the end face of the transducer mounting seat 2 away from the metering pipe section 1. And an inwardly concave lead groove 24 is formed between them on the end face of the transducer mounting seat 2 away from the metering pipe section 1. The two ends of the lead groove 24 are respectively connected to the assembly hole 21 and the wire passing hole 22. That is, the signal wire can be introduced into the wire passing hole 22 through the lead groove 24, making the threading of the signal wire more simple and fast, and reducing the threading difficulty.

[0026] In this embodiment, in order to further avoid damage to the signal wire and the transducer, an installation cover 4 is provided at the end of the transducer mounting seat 2 away from the metering pipe section 1. The installation cover 4 is used to cover the assembly hole 21, the wire passing hole 22, and the lead groove 24. And the installation cover 4 is detachably connected to the transducer mounting seat 2. Specifically, the transducer mounting seat 2 and the installation cover are detachably connected through a fastener 5.

Part of the transducer mounting base 2 is fixedly connected to the side wall of the outer surface of the connecting cylinder 31. A connecting hole 32 is provided on the connecting cylinder 31. The position of the connecting hole 32 corresponds to the wire passing cavity 23. The connecting hole 32 communicates the wire passing cavity 23 with the inside of the connecting cylinder 31, and the signal wire can enter the inside of the connecting cylinder 31 through the connecting hole 32. At the same time, in order to facilitate tube observation and the aesthetics of the ultrasonic water meter, the connecting cylinder 31 is arranged directly above the main pipe section 11.

[0028] In this embodiment, four transducer mounting bases 2 are provided. Two transducer mounting bases 2 are respectively provided on both side walls of the main pipe section 11. The transducer mounting bases 2 are arranged obliquely relative to the main pipe section 11, and the assembly holes 21 in the two transducer mounting bases 2 forming a diagonal are symmetrically arranged to ensure the stability and effectiveness of the ultrasonic signal propagation.

[0029] In this embodiment, the transducer mounting base 2 can be fixed to the metering pipe section 1 and the header mounting structure by laser welding, improving the reliability of the fixation between the transducer mounting base 2 and the metering pipe section 1 and the header mounting structure.
