Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic flowmeters, and more specifically, particularly relates to a wireless intelligent liquid flowmeter. Background Art

[0002] Ultrasonic flowmeter is an instrument that uses ultrasonic technology to measure fluid flow. Its working principle is to calculate the flow rate of the fluid by measuring the speed difference when ultrasonic waves propagate downstream and upstream in the fluid, and then determine the flow rate based on parameters such as the pipe cross-sectional area. It does not directly contact the fluid, does not interfere with the fluid, and also avoids corrosion and wear caused by contact with the fluid. It can be installed and maintained without interrupting fluid transportation, and is widely used in the field of liquid measurement.

[0003] Ultrasonic flow meters can automatically detect their own working status, such as whether the sensor is normal, whether the circuit is faulty, etc., and issue alarms or prompts in time. According to different fluid characteristics, environmental conditions, etc., they can automatically adjust measurement parameters or algorithms to improve measurement accuracy and reliability. They can interact and share data with other smart devices or systems to facilitate remote monitoring and management. Through wireless communication technologies such as Bluetooth, Wi-Fi, and ZigBee, flow data can be transmitted to remote terminals or monitoring systems in real time without wiring, which is convenient for data collection and monitoring. The above functions of ultrasonic flow meters (intelligence, wireless connection) are mature existing technologies.

[0004] An ultrasonic flow meter generally includes a flow meter body and two ultrasonic generators connected to it. Common ultrasonic flow meters and generators are fixed to the pipeline through clamps. The following problems are found during use:

[0005] 1. When other pipes are installed above, below or on both sides of the pipe that needs to monitor flow, if the two pipes are adjacent, it is impossible to install the clamp. At the same time, if the space around the pipe in a certain direction is limited, it is not convenient to install the flow meter and the clamp;

[0006] 2. The flow meter and ultrasonic generator fixed by the clamp are easy to loosen, and the flow meter and generator can be easily disassembled by random personnel, which has low safety.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, when the position relationship between the pipeline where the flow meter is installed and the adjacent pipeline is as follows: Figure 1 When the pipe is mounted on the pipe, the first and second mounting bases are spliced ​​together by the inserts and the slots, and the two pairs of connecting frames spliced ​​together are pulled to drive the pipe hook to move upward, so that the pipe can be inserted between the pipe hook and the mounting base to complete pre-fixation. The spliced ​​mounting bases one and two are hung on the pipe through the two pipe hooks. The elastic force of the second spring cooperates with the rubber anti-slip layer on the pipe hook to fix the entire device on the pipe so that it is not easy to shift. Then the limiting screw ring is rotated to make it against the limiting frame, so that the sliding piece connected to the limiting frame can no longer shift upward.

[0021] In the present invention, when the position relationship between the pipeline where the flow meter is installed and the adjacent pipeline is as follows: Figure 8When installing, first use the pipe hook to pre-install the mounting base 1 and the mounting base 2 on the pipe, the mounting base 1 and the mounting base 2 are spliced ​​together through four staggered staggered blocks, and then the extension rod is rotated to separate it from the deflection rod, and the extension rod is inserted into the circular groove 3, and the positioning pin is inserted into the slot 3 to complete the positioning of the extension rod, and the rectangular bar at the end of the extension rod is inserted into the slot 1 to ensure the verticality of the deflection plate, so that the two ultrasonic generators can be kept in contact with the surface of the pipe, further improving the applicability, and the appropriate installation method can be selected according to the different spatial conditions of the pipe where the flow meter is installed and the adjacent pipes.

[0022] In the present invention, when the mounting base one and the mounting base two are spliced ​​front and back through the insert plate and the card slot, the extension rod is inserted into the through slot, and the right end of the extension rod is located in the bottom slot. At this time, the elastic force of the spring one is used to keep the positioning pin in the slot two, thereby fixing the position of the extension rod, so that the splicing of the mounting base one and the mounting base two remains stable, and the mounting base one and the mounting base two are not easy to separate from the outside. Similarly, the mounting base one and the mounting base two can only be separated by operating the short frame after moving the moving plate, which further improves the safety and prevents the device from being disassembled.

[0023] In the present invention, the two convex grooves on the second mounting base are engaged with the two convex slides, and the end of the anti-loss rod passes through the rod groove and is sleeved on the positioning pin. The positioning pin simultaneously limits the anti-loss rod and the extension rod.

Using the positioning pin 18 to limit the anti-lost rod 48 is equivalent to limiting the position of the ultrasonic flowmeter body 3, thereby preventing the ultrasonic flowmeter body 3 from being moved, further improving safety, and ensuring the stability of monitoring;

[0042] The tops of the two fixed sleeves 8 are movably sleeved with a slide bar 30, and the two slide bars 30 are sleeved with a second spring 31, and the bottoms of the two slide bars 30 are fixedly connected with a slide plate 32, which is located in the fixed sleeve 8, and the second spring 31 is in a compressed state.

Similarly, the mounting base 1 and the mounting base 2 can only be separated by moving the moving sheet 14 and then operating the short frame 19, which further improves the safety and prevents the device from being disassembled;

[0047] The two convex grooves 5 on the mounting base 2 are engaged with the two convex slide seats 51, and the end of the anti-lost rod 48 passes through the rod groove 13 and is sleeved on the positioning pin 18. The positioning pin 18 simultaneously limits the anti-lost rod 48 and the extension rod 43. The use of the positioning pin 18 to limit the anti-lost rod 48 is equivalent to limiting the position of the ultrasonic flow meter body 3, thereby preventing the ultrasonic flow meter body 3 from being moved, further improving safety, and ensuring the stability of monitoring;

The ultrasonic generator 50 on the left is restricted by the extrusion screw 39 on the deflection plate 40 and is attached to the surface of the pipeline to achieve a stable monitoring effect. The ultrasonic generator 50 on the right is squeezed by the elastic pad 47 on the back of the ultrasonic flowmeter body 3 and is also attached to the surface of the pipeline, so that the two ultrasonic generators 50 can be kept on the surface of the pipeline to ensure the stability of monitoring.
