[0023] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described.

[0024] Please refer to Figures 1-3 As shown, the present utility model is a split ultrasonic water meter, including a water meter pipeline 1 and an ultrasonic water meter body 6 arranged at the central position of the upper end face of the water meter pipeline 1, and further including:

[0025] A connecting rod 2 is fixed on the upper end face of the water meter pipeline 1. An anti-slip pad 5 is arranged at the upper end of the water meter pipeline 1, and the anti-slip pad 5 is clamped with the lower end face of the ultrasonic water meter body 6. A locking mechanism is arranged on the outer side of the connecting rod 2 for limiting the position of the ultrasonic water meter body 6; Flange plates 3 are symmetrically arranged on the left and right sides of the water meter pipeline 1, and one end of the water meter pipeline 1 is a groove. By arranging the flange plates 3, it is convenient to connect the water meter pipeline 1 subsequently, so as to facilitate subsequent processing. Then, the arranged groove can ensure the connection effect of the water meter pipeline 1, and can prevent the water meter pipeline 1 from shifting and having gaps, which may affect the subsequent connection effect. At the same time, the ultrasonic water meter body 6 can be detachably connected to the connecting rod 2, which is convenient for subsequent disassembly of the ultrasonic water meter body 6;

[0026] Ultrasonic transceivers 4 are arranged on the left and right sides inside the water meter pipeline 1. By arranging two groups of ultrasonic transceivers 4, they can be connected to a power module and an MCU control unit installed inside the ultrasonic water meter body 6. Then, the MCU control unit and the ultrasonic transceivers 4 can be connected in a wireless connection manner for data transmission, so that when the water meter pipeline 1 and the ultrasonic water meter body 6 are separated, there is no restraint of wires; The locking mechanism includes a limit groove 7, a locking plate 8 and a return spring 10. The limit groove 7 is opened on the outer side of the connecting rod 2. The locking plate 8 is slidably clamped inside the limit groove 7, and the cross section of the locking plate 8 is a "Z" - shaped structure. The return spring 10 is arranged inside the limit groove 7, and the other end of the return spring 10 is connected to the locking plate 8. By arranging the limit groove 7, the position of the locking plate 8 can be limited to prevent the locking plate 8 from shifting. Then, the arranged return spring 10 can reset the locking plate 8 for subsequent processing;

[0027] One side of the locking plate 8 is provided with an inclined slope 9. The outer surface of the connecting rod 2 is evenly provided with thread rings 11. The outer surface of the connecting rod 2 is threadedly connected with an adjusting sleeve 12, and the adjusting sleeve 12 is sleeved on the outer surface of the ultrasonic water meter body 6 through the thread rings 11. The upper end inside the adjusting sleeve 12 is provided with a pressing slope 13, and the pressing slope 13 can be closely attached to the inclined slope 9. By setting the adjusting sleeve 12 to be rotatable, the adjusting sleeve 12 can be pushed upward through the thread rings 11. The inner pressing slope 13 of the adjusting sleeve 12 can contact the inclined slope 9, so that the position of the locking plate 8 can be adjusted to facilitate subsequent locking.

[0028] During use, keep the ultrasonic water meter body 6 and the connecting rod 2 horizontal, and embed the anti-slip pad 5 into the ultrasonic water meter body 6. Then, screw the adjusting sleeve 12 upward through the thread rings 11. The pressing slope 13 can contact the inclined slope 9, so that the locking plate 8 can be moved inward, so as to be connected to the card slot at the lower end of the ultrasonic water meter body 6, thereby avoiding the deviation and shaking of the ultrasonic water meter body 6. When the adjusting sleeve 12 is screwed downward, the set return spring 10 can reset the locking plate 8 to facilitate subsequent processing.

[0029] A cover plate body 15 is arranged at the upper end of the ultrasonic water meter body 6. A locking collar 14 is arranged on the upper end surface of the ultrasonic water meter body 6, and the locking collar 14 is connected to the cover plate body 15 for protecting the electronic components in the ultrasonic water meter body 6.
