Description

Technical Field

[0001] The present invention relates to the technical field of flow meters, and more particularly to an intelligent flow meter. Background Art

[0002] Measurement is the eye of industrial production. Flow measurement is one of the components of measurement science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, the status and role of flow meters in the national economy are more obvious.

[0003] The patent with patent application publication number CN201820542318 discloses a vortex flowmeter, which can be connected to the measured pipeline by screws passing through the mounting flange. The measured medium in the pipeline enters the measuring pipeline through the mounting flange, shock-absorbing bellows, and mounting plate and is measured by the flowmeter body. The flow rate of the medium can be measured according to the Karman vortex principle.

[0004] However, the above technical solution still has many shortcomings when it is actually used. For example, it only performs measurement work intelligently and cannot adjust when the flow is abnormal, requiring staff to monitor for a long time. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an intelligent flow meter, which is provided with a top seat and a flow control plate. The liquid enters the main body through the connecting seat and passes through two rotating seats in sequence. When the liquid flow rate is too fast and exceeds the warning value, the PLC controller inside the control shell controls the electric push rod to push the flow control plate downward. The liquid in the main body needs to pass through the rotating seat, the flow control plate and the rotating seat before leaving the main body. After passing the rotating seat, the liquid passes through the flow control hole inside the flow control plate or flows from the outside of the flow control plate, which greatly reduces the flow space of the liquid and effectively reduces the flow rate of the liquid.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent flow meter, comprising a main body, connecting seats are provided on both sides of the main body, fixed seats are provided on the top and bottom of the inner wall of the main body, a rotating seat is provided between the two fixed seats, a protruding strip is provided around the surface of the rotating seat, the top of the main body is connected with a top seat, a flow control plate is provided inside the top seat, an external seat is fixedly provided on the top of the top seat, and a control shell is provided on the top of the external seat.

[0007] In a preferred embodiment, a pressure-resistant pad is arranged around the inner wall surface of the main body, and the fixing seat is arranged on the surface of the pressure-resistant pad.

[0010] In a preferred embodiment, electric push rods are evenly arranged between the flow control plate and the top of the inner wall of the top seat, and infrared sensors are arranged on the outer sides of the electric push rods.

[0011] In a preferred embodiment, the flow control plate is shaped as a cylinder, flow control holes are evenly arranged inside the flow control plate, pressure sensors are arranged around the outside of the flow control holes, and the pressure sensors are arranged inside the flow control plate.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The present invention is provided with a top seat and a flow control plate. The liquid enters the main body through the connecting seat and passes through two rotating seats in sequence. When the liquid flow rate is too fast and exceeds the warning value, the PLC controller inside the control shell controls the electric push rod to push the flow control plate downward. The liquid in the main body needs to pass through the rotating seat, the flow control plate and the rotating seat before leaving the main body. After passing through the rotating seat, the liquid passes through the flow control hole inside the flow control plate or flows from the outside of the flow control plate, which greatly reduces the flow space of the liquid and effectively reduces the flow rate of the liquid.

[0015] 2. The present invention is provided with a top seat and a protruding strip. The liquid enters the interior of the main body through the connecting seat and passes through two rotating seats in sequence. After the triangular diamond-shaped protruding strips evenly arranged on the surface of the rotating seat come into contact with the liquid, the rotating seat receives the impact force of the liquid and rotates. During the rotation process, the liquid is pushed out from the outside of the rotating seat and passes through another rotating seat. The liquid continuously passes through the two rotating seats to reduce the flow speed of the liquid. At the same time, the rotation rate of the rotating seat can be measured according to the torque sensor inside the rotating seat;

[0016] 3. By providing a control shell and an alarm, the torque sensor inside the rotating seat detects the rotation rate of the rotating seat, and the laser sensor on the top of the inner wall of the top seat detects the rotation rate of the rotating seat. According to the different speeds of the two rotating seats, it can be calculated whether the flow rate of the liquid exceeds the warning value. When the flow control plate is used, the pressure sensor inside the flow control plate detects the water pressure intensity passing through the flow control hole to ensure the stable transmission of the liquid pressure. When it exceeds the warning value, the PLC controller controls the alarm 82 to sound to remind the staff to check the equipment, thereby achieving the effect of intelligent work.

[0025] A pressure-resistant pad 11 is disposed around the inner wall surface of the main body 1 , and the fixing seat 3 is disposed on the surface of the pressure-resistant pad 11 .

[0026] A connecting column 21 is provided inside the connecting seat 2 , and the connecting column 21 matches the main body 1 . Mounting holes 22 are evenly provided on the surface of the connecting seat 2 .

[0027] A rotating shaft 31 is provided between the two fixing seats 3, the rotating shaft 31 is fixedly connected to the fixing seats 3, the rotating seat 4 matches the rotating shaft 31 and is slidably connected to the rotating shaft 31, a torque sensor is provided inside the rotating seat 4, and the protruding strip 41 is shaped as a triangular column.

[0028] The specific implementation method is as follows: the liquid enters the main body 1 through the connecting seat 2 and passes through the two rotating seats 4 in sequence. After the triangular rhombus protrusions 41 evenly arranged on the surface of the rotating seat 4 come into contact with the liquid, the rotating seat 4 receives the impact force of the liquid and rotates. During the rotation, the liquid is pushed out from the outside of the rotating seat 4 through the other rotating seat 4. The liquid continuously passes through the two rotating seats 4 to reduce the flow speed of the liquid, and at the same time, the rotation rate of the rotating seat 4 can be measured according to the torque sensor inside the rotating seat 4.

[0029] according to Figure 1 and Figure 4 In the intelligent flow meter shown in the figure, electric push rods 51 are evenly arranged between the flow control plate 6 and the top of the inner wall of the top seat 5, and infrared sensors 52 are arranged on the outer side of the electric push rods 51, and the model of the infrared sensor is SE470.

[0030] The shape of the flow control plate 6 is set to be cylindrical, and the flow control holes 61 are evenly arranged inside the flow control plate 6. A pressure sensor is arranged around the outside of the flow control holes 61. The pressure sensor is arranged inside the flow control plate 6, and the model of the pressure sensor is PTG500.

[0031] The control housing 8 is provided with a data transmission module, a data processing module and a PLC controller inside, the control housing 8 is provided with a control panel 81 on the surface, an alarm 82 is provided on the top of the control housing 8, and a display light 83 is provided on one side of the alarm 82.

[0032] The specific implementation method is as follows: the liquid enters the main body 1 through the connecting seat 2 and passes through the two rotating seats 4 in turn. When the liquid flow rate is too fast and exceeds the warning value, the PLC controller inside the control shell 8 controls the electric push rod 51 to push the flow control plate 6 to move downward. The liquid in the main body 1 needs to pass through the rotating seat, the flow control plate 6 and the rotating seat 4 before leaving the main body 1. After passing through the rotating seat 4, the liquid passes through the flow control hole 61 inside the flow control plate 6 or flows from the outside of the flow control plate 6, which greatly reduces the flow space of the liquid and effectively reduces the flow rate of the liquid.

[0033] Working principle of the present invention:

[0034] Refer to the instruction manual Figure 1-3 : The liquid enters the main body 1 through the connecting seat 2 and passes through the two rotating seats 4 in sequence. After the triangular diamond-shaped protruding strips 41 evenly arranged on the surface of the rotating seat 4 come into contact with the liquid, the rotating seat 4 receives the impact force of the liquid and rotates. During the rotation process, the liquid is pushed out from the outside of the rotating seat 4 and passes through the other rotating seat 4. The liquid continuously passes through the two rotating seats 4 to reduce the flow speed of the liquid. At the same time, the rotation rate of the rotating seat 4 can be measured according to the torque sensor inside the rotating seat 4;

[0035] Refer to the instruction manual Figure 1 , Figure 2 and Figure 4 : The liquid enters the main body 1 through the connecting seat 2 and passes through the two rotating seats 4 in turn. When the liquid flow rate is too fast and exceeds the warning value, the PLC controller inside the control housing 8 controls the electric push rod 51 to work and push the flow control plate 6 to move downward. The liquid in the main body 1 needs to pass through the rotating seat, the flow control plate 6 and the rotating seat 4 before leaving the main body 1. After passing through the rotating seat 4, the liquid passes through the control flow hole 61 inside the flow control plate 6 or flows from the outside of the flow control plate 6, which greatly reduces the flow space of the liquid and effectively reduces the flow rate of the liquid;

[0036] Refer to the instruction manual Figure 1-5 : The torque sensor inside the rotating seat 4 detects the rotation rate of the rotating seat 4, and the laser sensor 52 on the top of the inner wall of the top seat 5 detects the rotation rate of the rotating seat 4. According to the different rates of the two rotating seats 4, it can be calculated whether the flow rate of the liquid exceeds the warning value. When the flow control plate 6 is used, the pressure sensor inside the flow control plate 6 detects the water pressure intensity passing through the flow control hole 61 to ensure the stable transmission of the liquid pressure. When it exceeds the warning value, the PLC controller controls the alarm 82 to sound to remind the staff to check the equipment, thereby achieving the effect of intelligent work.
