[0002] Flow meters, as devices capable of real-time monitoring of liquid flow, are widely used in industrial automation, agricultural irrigation, and laboratory systems. However, some existing flow meters or flow monitoring devices often require drilling or welding into existing pipelines during installation. This is not only cumbersome but, more importantly, can cause permanent damage to the pipeline. For example, Chinese patent CN201711214191.1 discloses an online calibration device for large-diameter liquid flow meters. While this solves the calibration problem in specific scenarios, its installation process remains complex and may involve temporary or permanent modifications to the pipeline structure. These installation methods are not only cumbersome and time-consuming, but more importantly, they can cause irreversible damage to the pipeline system, increasing potential leakage risks and subsequent maintenance costs.

Limiting mechanisms are respectively disposed on both sides of the housing 1 for clamping and fixing the liquid pipes from the outside. The mechanism includes mounting seats 6 fixedly installed on both sides of the housing 1, a bidirectional screw 7 rotatably connected to the mounting seats 6 via bearings and passing through the mounting seats 6, threaded sleeves 8 screwed onto the two reverse threads of the bidirectional screw 7, a movable seat 9 fixedly connected to the threaded sleeves 8, a first limiting ring 10 fixedly connected to the side of the movable seat 9, a synchronous disc 11 slidably installed inside the movable seat 9, a T-shaped rod 12 sleeved on the outside of the synchronous disc 11, and a second limiting ring 13 fixedly connected to the T-shaped rod 12; and a locking structure, which is located above the mounting seats 6 and is used to lock the rotational position of the bidirectional screw 7.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the box body 1 is fitted with a cover using countersunk screws. One side of the box body 1 has a water outlet corresponding to the water outlet glass tube 3, and includes a reset interface 20 and a power cord interface 21. The other side of the box body 1 has a water inlet corresponding to the water inlet glass tube 2, and includes a water inlet vent 22 and an expansion interface 23 for connecting external sensors or indicator lights to meet the needs of power supply, reset, ventilation, and external device expansion. Sealing rings 24 are bonded to the inner walls of both the water inlet glass tube 2 and the water outlet glass tube 3 to ensure a tight seal at the connection. A slider is fixedly mounted on the side of the screw sleeve 8, and the inner wall of the mounting base 6 has a groove that fits the slider. The slider is embedded in the groove and can slide along it.

[0020] like Figure 1 , Figure 4 and Figure 6As shown, both the movable seat 9 and the fixed seat 16 have accommodating cavities inside. A first anti-slip pad is adhered to the inner side of the first limiting ring 10, and a second anti-slip pad is adhered to the inner side of the second limiting ring 13. The synchronous disc 11 includes a central column and end discs fixedly connected. The end of the T-shaped rod 12 is slidably installed inside the movable seat 9. The end of the T-shaped rod 12 has a through hole adapted to the central column, through which the central column passes. The two end discs are located on both sides of the end of the T-shaped rod 12. A first bolt is fixedly connected to the side of the upper synchronous disc 11 and screwed to the upper movable seat 9. The bottom of the upper movable seat 9 has a first sliding opening for the upper T-shaped rod 12 to slide. A second bolt is fixedly connected to the side of the lower synchronous disc 11 and screwed to the lower movable seat 9. The top of the lower movable seat 9 has a second sliding opening for the lower T-shaped rod 12 to slide. By rotating the first bolt and the second bolt, the synchronous disc 11 can be driven to slide within the movable seat 9.

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, the locking structure includes a rotating disk 14 slidably sleeved on the outside of the bidirectional screw 7, a locking pin 15 and a fixing seat 16 fixedly installed above the mounting base 6, a fixing rod 17 fixedly installed inside the fixing seat 16, a pressure rod 18 slidably sleeved on the outside of the fixing rod 17, and a spring 19 sleeved on the outside of the fixing rod 17. A guide key is fixedly installed on the outside of the bidirectional screw 7. The rotating disk 14 has a keyway adapted to the guide key. The side of the rotating disk 14 has locking holes arranged in a circular array. The locking pin 15 can selectively extend into any of the locking holes. The spring 19 is located between the pressure rod 18 and the fixing seat 16. The pressure rod 18 abuts against the side of the rotating disk 14. The side of the fixing seat 16 has a third sliding opening for the pressure rod 18 to slide.

[0022] Working process: First, insert the two liquid pipes of the system to be monitored into the inlet glass tube 2 and the outlet glass tube 3, respectively. The built-in sealing ring 24 will form a tight contact with the outer wall of the liquid pipe to ensure the sealing of the connection. Then, pull the rotating disk 14 of the locking structure upward to overcome the elastic force of the spring 19. The locking pin 15 will disengage from the locking hole of the rotating disk 14. At the same time, rotating the rotating disk 14 can drive the bidirectional screw 7 of the limiting mechanism to rotate. The bidirectional screw 7 can drive the screw sleeves 8 on both sides, the movable seat 9 and the first limiting ring 10. The components move towards each other until the first anti-slip pad on the first limit ring 10 is tightly pressed against the upper and lower parts of the outer wall of the liquid pipe, completing the initial clamping of the liquid pipe in the vertical direction. Then, the rotating disk 14 is released, the spring 19 returns to its original position, and the pressure rod 18 pushes the rotating disk 14 downward. The locking pin 15 extends into the locking hole at the corresponding position to prevent the bidirectional screw 7 from reversing. Subsequently, rotating the first bolt and the second bolt can drive the synchronous disk 11 to move horizontally within the movable seat 9. Since the end of the T-shaped rod 12 is sleeved on the central column of the synchronous disk 11 through the through hole, The movement of the synchronous disc 11 will drive the T-shaped rod 12 and the second limiting ring 13 fixed thereto to move horizontally until the second anti-slip pad on the second limiting ring 13 is in close contact with the left and right sides of the outer wall of the liquid pipe. At this point, the liquid pipe is firmly clamped from four directions by the first limiting ring 10 and the second limiting ring 13. No holes or welding are required on the pipe, which realizes completely non-destructive and rapid installation and disassembly, protects the integrity of the pipe, greatly facilitates on-site construction and maintenance, and ensures the stability of the connection during monitoring. Then, the power is turned on at the power cord interface 21. The liquid flows through the inlet glass tube 2, the drip sensor 4 and the outlet glass tube 3. The drip sensor 4 transmits the detected flow signal to the four-input two-output programmable control board 5 in real time. The control board 5 processes the signal according to the preset program (such as flow threshold, time control and other logic) and can control the action of external actuators (such as solenoid valves, water pumps, etc.) through its output interface to realize automated management. The system can be reset through the reset interface 20 and connected to the front sensor or status indicator through the expansion interface 23.
