Description

Technical Field

[0001] The present invention belongs to the technical field of flowmeters, and more specifically, particularly relates to a multi-parameter low-power consumption flowmeter. Background Art

[0002] A flow meter is an instrument used to measure the flow of fluid in a pipeline or open channel. Its function is to accurately determine the volume or mass of fluid passing through the pipeline or channel per unit time, thereby helping to achieve production process monitoring, energy management, cost accounting and process control. Before installation, ensure that the inside of the pipeline is clean and free of debris and dirt. For environments susceptible to corrosion or pollution, appropriate protective measures should be taken.

[0003] 1. When the fluid passes through the turbine, it drives the turbine blades to rotate. The speed of the turbine is proportional to the flow rate of the fluid. The flow rate is determined by measuring the speed of the turbine. However, it also flows inside the pipeline and is easily affected by the temperature outside the pipeline. However, the flow meter can only count the flow inside the pipeline, and the data that can be monitored is limited.

[0004] 2. During the internal flow of the liquid pipeline, the liquid may not be able to fill the entire pipeline, resulting in the liquid only being able to flow in half of the space in the pipeline. The impact force of the liquid on the blade is relatively small and cannot generate sufficient power. The rotation speed of the blade is not proportional to the flow rate, which will cause data errors in the actual measurement process.

[0005] 3. When the flow rate of the fluid in the pipeline is high, or the fluid flow at the inlet is uneven or the flow direction changes suddenly, turbulence is likely to occur. In the turbulent state, the fluid flows in an irregular and chaotic manner, which will continuously and repeatedly impact the blades, easily causing structural damage to the blades. Summary of the invention

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the present invention, the flow rate is determined by measuring the rotation speed of the gear ring, and the flow rate is displayed in real time by an indicator. At the same time, the second measuring blade drives the temperature sensor to rotate together, and the temperature sensor detects the temperature of the liquid inside the shell. At the same time, two liquid level sensors are installed on the side end of the installation frame, and the two liquid level sensors are respectively located at the top and bottom of the installation frame. When the liquid level can only submerge one liquid level sensor, the telescopic rod is controlled by the control box, and the control box drives the telescopic rod to extend and retract, which not only detects the temperature inside the shell, but also measures the liquid height inside the shell and adjusts the switch of the paddle.

[0012] In the present invention, by pushing the two first measuring blades to rotate, one end of the first measuring blade is rotatably connected to the first rotating rod, and through the connection of the bevel gear, the first rotating rod is pushed to rotate inside the installation frame, and the first ferrule is engaged with the second ferrule.

The guide plates guide the liquid, and the conical cylinder buffers and blocks the liquid. At the same time, the liquid continues to flow to the interior of the shell through the opening at the side end of the first fixed plate.

A nozzle is fixedly installed on the side end of the lubrication box. The nozzle regularly introduces the lubricating oil into the end of the second measuring blade to lubricate the connection between the second measuring blade and the transmission rod, thereby reducing friction loss.

[0015] In the present invention, the slider is allowed to slide inside the installation frame, the slider drives the positioning ring to move toward the inner wall of the installation frame, the slider pulls one end of the second buffer rod to allow the second buffer rod to retract, and at the same time, a plurality of plug rods are installed on the side end of the positioning ring, the plug rods penetrate the side end of the installation frame, fit with the transmission rod, fix and restrict the transmission rod, and at the same time limit the rotation of the second measuring blade, while adjusting the switch between the first measuring blade and the second measuring blade, preventing the vortex generated by the rotation of the second measuring blade from affecting the first measuring blade.

[0016] In the present invention, a battery assembly and a control circuit board are installed inside the control box. The battery assembly is responsible for providing power to the system. Through the control circuit board, the timing switch can power the control box and the indicator to ensure that they can work normally when needed.

[0030] Working principle:

[0031] In the first step, a battery assembly, a control circuit board, and a signal converter are installed inside the control box 15. The battery assembly is responsible for providing power to the system. In addition, the system also includes a sophisticated timer switch, which is responsible for accurately controlling the power supply time. Through the control circuit board, the timer switch can power the control box 15 and the indicator 17 to ensure that they can work normally when needed. The timer switch can also monitor the flow rate according to the preset time period. The control box 15 reduces the power consumption of the equipment. At the same time, the two ends of the shell 11 are respectively connected to the pipeline, and the liquid enters the interior of the shell 11 from one side of the conical cylinder 12. When the pipeline transports the liquid to the interior of the conical cylinder 12, the conical cylinder 12 itself has a conical design, and a plurality of guide plates 13 are installed on the inner wall of the conical cylinder 12. The guide plates 13 guide the liquid, and the conical cylinder 12 buffers and blocks the liquid. At the same time, the liquid continues to flow into the interior of the shell 11 through the opening at the side end of the first fixed plate 14. The liquid impacts the surface of the baffle body 24, and the baffle body 24 is forced to move to one side, pulling the first buffer rod 25 to retract and contract, playing a buffering role, intercepting the turbulence generated in the pipeline, and preventing the turbulence from impacting the first measuring blade 21 and the second measuring blade 22, causing damage.

[0032] The liquid flows inside the housing 11, impacting the surface of the second measuring blade 22, causing the second measuring blade 22 to rotate at the side end of the mounting frame 31. One end of the second measuring blade 22 is connected to the transmission rod 26 through a bevel gear. At the same time, the transmission rod 26 rotates inside the mounting frame 31, causing the transmission rod 26 to drive the gear ring 27 to rotate inside the control box 15. The gear ring 27 is connected to the counting gear inside the control box 15. The rotation speed of the second measuring blade 22 is proportional to the flow rate of the liquid. The flow rate is determined by measuring the rotation speed of the gear ring 27. The flow rate is displayed in real time by the indicator 17. At the same time, the second measuring blade 22 drives the temperature sensor 23 to rotate together. The temperature sensor 23 detects the liquid temperature inside the housing 11. At the same time, two liquid level sensors 19 are installed at the side end of the mounting frame 31. The two liquid level sensors 19 are respectively located at the top and bottom of the mounting frame 31. When the liquid level can only submerge one liquid level sensor 19, the telescopic rod 41 is controlled by the control box 15, and the control box 15 drives the telescopic rod 41 is extended and retracted, and the telescopic rod 41 is extended and retracted downward to generate a thrust on the second rotating rod 34, so that the second rotating rod 34 slides at the bottom end of the rotating card seat 33. The rotating card seat 33 itself is a retractable structure. It can be stretched while rotating. By pushing the second rotating rod 34 to move downward, the second rotating rod 34 drives the first clamping sleeve 35 to move toward the second clamping sleeve 36. The top of the second clamping sleeve 36 is provided with a plurality of grooves, and the bottom of the first clamping sleeve 35 is installed with a plurality of protrusions. The first clamping sleeve 35 and the second clamping sleeve 36 are clamped and fit with each other. At the same time, a lubrication box 38 is fixedly installed on the inner side of the installation frame 31, and a connecting pipe 47 is installed on the top of the lubrication box 38. The connecting pipe 47 passes through the interior of the control box 15 and is connected to the storage box 16. Lubricating oil is stored in the storage box 16, and the lubricating oil is introduced into the interior of the lubrication box 38 through the connecting pipe 47. A nozzle 43 is fixedly installed on the side end of the lubrication box 38. The nozzle 43 regularly introduces the lubricating oil into the end of the second measuring blade 22 to lubricate the connection between the second measuring blade 22 and the transmission rod 26 to reduce friction loss.

[0033] In the second step, a downward thrust is applied to the second rotating rod 34 through the telescopic rod 41, so that the second rotating rod 34 drives the collar 42 to move downward. At the same time, the collar 42 pushes the top of the push rod 46. The end of the push rod 46 is installed at the top of the slider 44. The slider 44 is applied with a horizontal force through the inclined push rod 46 to slide the slider 44 inside the installation frame 31. The slider 44 drives the positioning ring 39 to move toward the inner side wall of the installation frame 31. The slider 44 pulls one end of the second buffer rod 45 to allow the second buffer rod 45 to be extended and retracted. At the same time, a plurality of plug rods are installed on the side end of the positioning ring 39. The plug rods penetrate the side end of the installation frame 31 and fit with the transmission rod 26 to push the transmission rod 26. The second measuring blade 22 is fixedly restricted and the rotation of the second measuring blade 22 is restricted. When the flow inside the pipeline decreases, the two first measuring blades 21 are pushed to rotate. One end of the first measuring blade 21 is rotatably connected to the first rotating rod 32. The first rotating rod 32 is pushed to rotate inside the mounting frame 31 through the connection of the bevel gear. At the same time, the first ferrule 35 is engaged with the second ferrule 36. The second rotating rod 34 and the rotating holder 33 are driven to rotate at the bottom end of the control box 15. The flow inside the housing 11 is tested by the rotation speed of the first measuring blade 21. At the same time, the first measuring blade 21 and the second measuring blade 22 cooperate with each other, and the measurement position can be adjusted according to the flow inside the housing 11.

[0034] When the flow rate inside the housing 11 is large, the liquid flowing to one side impacts the first measuring blade 21, which may easily cause the first measuring blade 21 to rotate in the opposite direction, affecting the accuracy of the detection. At this time, the liquid surface submerges the two liquid level sensors 19, and the liquid level sensor 19 transmits a signal to the control box 15. The control circuit board inside the control box 15 responds, drives the telescopic rod 41 to extend and retract upward, and generates an upward force on the second rotating rod 34, so that the second rotating rod 34 slides upward at the bottom end of the rotating card seat 33. At the same time, the second rotating rod 34 drives the first card sleeve 35 to move upward, so that the first card sleeve 35 is disconnected from the second card sleeve 36. At the same time, the second rotating rod 34 moves upward, so that the second rotating rod 34 moves upward. The rod 34 pulls the push rod 46 upward, and the push rod 46 is deflected upward by the force. The push rod 46 generates an oblique pulling force on the slider 44, allowing the slider 44 to slide horizontally inside the mounting frame 31. At the same time, the slider 44 squeezes the second buffer rod 45 at the side end, forcing the second buffer rod 45 to be compressed. At the same time, the slider 44 drives the positioning ring 39 to move, allowing the positioning ring 39 to leave the inner wall of the mounting frame 31, allowing the positioning ring 39 to drive the insertion rod on one side to leave the inside of the transmission rod 26, thereby releasing the fixation of the transmission rod 26. Under the flow of liquid, the surface of the second measuring blade 22 is impacted, and the second measuring blade 22 is driven to rotate at the side end of the mounting frame 31 again to measure the flow rate of the liquid.
