[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figures 1 to 5 This utility model discloses a single-channel gas ultrasonic detection device, including an ultrasonic detection unit 5, which includes a detection channel, ultrasonic transducers on both sides of the detection channel, and symmetrically arranged ultrasonic probes 6 inside the ultrasonic detection unit 5.

[0020] In this embodiment, the ultrasonic detection unit 5 extends into the chimney 7 to be tested. Considering the ease of installation of the ultrasonic gas flow meter, a single-end insertion installation is adopted for the sampling hole 8 of the chimney 7. It should be noted that the sampling hole 8 and the sampling position comply with the relevant provisions in GB / T 16157, requiring no drilling or tilting angle, and is applicable to various sampling hole 8 specifications, preferably any one of DN80, DN100, and DN125, thus solving the problem of drilling holes for installation on the chimney 7.

[0021] It should be noted that: The ultrasonic probe 6 converts electrical energy into mechanical energy, i.e., ultrasonic waves, through the inverse piezoelectric effect. When the ultrasonic waves encounter an object, some of them are reflected back. These reflected waves act on the piezoelectric crystal of the probe, causing it to generate an alternating electric field under alternating tension and pressure. The electrical signals received by the probe are transmitted to the ultrasonic host for processing and are finally displayed on the screen as images or data for diagnosis or measurement.

[0022] The connecting assembly includes a flange 3, which is connected to the outer surface of the insert rod 1.

[0023] See Figure 4 and Figure 5 A sampling hole 8 is provided on the side wall of the chimney 7. An insertion rod 1 passes through the sampling hole 8 and extends into the chimney 7. The insertion depth of the insertion rod 1 is determined as needed, acting on the detection position. After the position is determined, it is fixed to the outer wall of the chimney 7 using a flange 3. The insertion rod 1 is a hollow structure, and a cable 2 is installed inside the insertion rod 1. The cable 2 runs through the insertion rod 1 and connects the ultrasonic testing unit 5 and the control box 4.

[0024] In this embodiment, a hollow insert rod 1 is provided to extend the ultrasonic detection unit 5 into the chimney 7. The cable 2 is passed through the insert rod 1, with one end connected to the ultrasonic detection unit 5 and the other end connected to the control box 4, so that the data collected by the ultrasonic detection unit 5 can be successfully transmitted to the control box 4.

[0025] It should be noted that plug 1 is both a support component and a protective sleeve for the signal output cable.

[0026] The control box 4 contains a power supply, and the power supply is electrically connected to an integrator, a microcontroller, and a signal acquisition module.

[0027] In this embodiment, a control box 4 is set up and operates outside the chimney 7. Data is transmitted to the control box 4 via a cable. The control box 4 integrates a signal processing unit and an integrator. The signal processing unit consists of a power supply, a microcontroller, and a signal acquisition module. It transmits basic data to the integrator. The integrator has the functions of processing the acquired signals, displaying, outputting, and recording the measurement results. It calculates the flow rate or velocity of the flue gas passing through the cross section of the entire chimney 7 and communicates the feedback to the CEMS system.

[0028] The flange 3 has a clamp on one side and an annular groove on one side, and a sealing ring is installed in the annular groove.

[0029] In this embodiment, a clamp is provided on one side of the flange 3 to enhance the stability of the connection between the flange 3 and the chimney 7. At the same time, a sealing ring is provided inside the flange 3 to reduce the friction of the installation mating surface and improve the installation stability of the plug rod 1.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
