Detailed implementation manners

[0027] The following Figure 1 - Figure 7 in conjunction with the attached

[0028] A voiceprint recognition fault warning device, referring to Figure 1 and Figure 4 , includes a fluid pipeline 1 for fluid to flow through, a group of measurement pipelines 2 for measuring fluid are flange-connected between two groups of fluid pipelines 1, a group of ultrasonic flowmeters 3 are fixedly connected to the top middle end of the measurement pipeline 2, which can measure the fluid in the measurement pipeline 2, and further includes a warning mechanism 4 installed at the outer end of the measurement pipeline 2.

[0029] Specifically, the fluid flows in the two groups of fluid pipelines 1, and when passing through the measurement pipeline 2, the ultrasonic flowmeter 3 measures the fluid.

[0030] Referring to Figures 1-3 , the warning mechanism 4 includes a connecting cylinder 41, a quick-release mechanism 42, an acquisition mechanism 43 and a fixing mechanism 44. The connecting cylinder 41 is installed at the outer middle end of the measurement pipeline 2, quick-release mechanisms 42 are connected to the front and rear ends of the connecting cylinder 41, an acquisition mechanism 43 is arranged at the top middle end of the connecting cylinder 41, and the acquisition mechanism 43 is connected to the fixing mechanism 44 at the rear end.

[0031] The components of the two sets of quick-release mechanisms 42 are all the same. The quick-release mechanism 42 includes side plates 421, limit frames 422, flanges 423, through grooves 424 and limit rods 425. The connecting cylinder 41 is provided in two parts, upper and lower, and a set of side plates 421 are fixedly connected to the front and rear ends of the upper and lower parts. A set of limit frames 422 are hinged to the right ends of the top side plates 421. Notches corresponding to the limit frames 422 are opened at the right ends of the bottom side plates 421, which is beneficial to the rotation of the limit frames 422. At least two sets of flanges 423 are fixedly connected to the upper and lower ends inside the limit frames 422. When the limit frames 422 rotate to the upper and lower ends of the two side plates 421, the two side plates 421 can be squeezed by the flanges 423, improving the tightness and stability of their fit. Through grooves 424 communicating with each other are opened in the middle of the upper and lower sets of side plates 421, and a set of limit rods 425 are slidably connected in the two through grooves 424.

[0032] Among them, the lengths of the limit rods 425 are all longer than the lengths of the through grooves 424, and the ends of the two limit rods 425 away from each other are both formed into arcs. When the upper and lower sets of side plates 421 are fitted together, the two limit rods 425 are squeezed against each other, causing the two limit rods 425 to extend towards the upper and lower ends respectively. When the limit frames 422 rotate to the upper and lower ends of the two side plates 421, they can be caught in the outer arc-shaped grooves, which is beneficial to the limitation of the limit frames 422.

Limit bumps 4212 corresponding to them are fixedly connected to the top surfaces of the lower side plates 421. The limit bumps 4212 can be adsorbed by the magnetic attraction plates and caught in the limit card slots 4211, which can improve the convenience of connecting the two side plates 421.

And not less than two groups of microphone arrays 434 are installed at the inner end of the movable cylinder 433, which can improve the acquisition efficiency of the working noise of the ultrasonic flowmeter 3. A set of identification modules 435 are installed at the bottom end of the right microphone array 434. The identification module 435 can analyze and identify whether there are cavitations or abrasives in the fluid through the differences in the working noise of the ultrasonic flowmeter 3, and can send signals to an external terminal for early warning.

[0036] Among them, an observation window 4331 is provided at the top middle end of the movable cylinder 433, facilitating the observation of the working condition of the ultrasonic flowmeter 3. Sound-absorbing cotton 4332 is adhered to the inner side of the movable cylinder 433. The sound-absorbing cotton 4332 can reduce noises such as echoes, making the sound clearer and improving the acquisition effect of the sound.

[0037] Specifically, the movable cylinder 433 is sleeved outside the ultrasonic flowmeter 3, the working noise is collected through the microphone array 434, and identification and early warning are carried out through the identification module 435 to give early warning to the staff.

The arc plate 443 can drive the sliding plate 444 and the movable cylinder 433 to rotate backward, exposing the ultrasonic flowmeter 3 inside the movable cylinder 433, facilitating the adjustment of the ultrasonic flowmeter 3; And a set of extension seats 445 are fixedly connected to both the left and right sides of the fixing arm 442. A set of connecting rods 446 are rotatably connected to the middle ends of the extension seats 445. The upper ends of the connecting rods 446 extend to the upper ends of the extension seats 445 and are fixedly connected to a set of locking arms 447. Corresponding second card slots are provided at the bottom front ends of the two locking arms 447 for the left and right ends of the top surface of the movable cylinder 433. The two locking arms 447 can be stuck to the left and right ends of the top surface of the movable cylinder 433, facilitating the limit of the movable cylinder 433; The lower ends of the connecting rods 446 all extend to the lower ends of the expansion seats 445 and are fixedly connected with a set of locking members 448.
