Description

Technical Field

[0001] This utility model relates to the field of flow meter testing technology, and in particular to an industrial flow meter testing platform. Background Technology

[0002] A flow meter is an instrument used to measure the flow rate of fluids. It obtains instantaneous flow rate or cumulative data by monitoring the volume or mass of fluid passing through a pipe per unit time. Common types include mechanical, electromagnetic, and ultrasonic flow meters. They are widely used in industrial control, energy metering, environmental monitoring, and other fields. Their measurement parameters include flow rate, pressure, and temperature, which are crucial for process optimization and resource management.

[0003] Traditional flow meter testing platforms have relatively simple flow meter testing components, making test results prone to errors. They rely on manual calibration, which is inefficient and complex to operate. Furthermore, traditional flow meter testing equipment is fixed and cannot be used for continuous testing. It also cannot detect defects on the inner wall of the flow tube, resulting in limited testing capabilities, large errors, and impacting yield rates and production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial flow meter testing platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial flow meter testing platform includes a base and a first motor fixedly mounted on the base. Multiple first rotating shafts are rotatably connected to the upper side of the base, and the multiple first rotating shafts are jointly connected to a conveyor belt. The output end of the first motor is fixedly connected to one of the first rotating shafts. A fixed seat is placed on the upper side of the conveyor belt, and a flow meter is placed on the upper side of the fixed seat. Multiple sets of testing components are fixedly connected to the upper side of the base. Each set of testing components includes two water tanks fixedly connected to the upper side of the base. The two water tanks are symmetrically mounted on both sides of the conveyor belt. A pressure pump is fixedly connected to the upper end of each water tank. A pipe is fixedly connected to one side of each water tank. A sliding tube is slidably connected inside the pipe. A moving plate is fixedly connected to one side of the sliding tube. A rack is fixedly connected to one side of the moving plate. A second motor and a sliding groove are fixedly mounted on the upper side of the base. A gear is fixedly connected to the output end of the second motor. A slider is fixedly connected to the lower side of the rack. The slider and the sliding groove are slidably connected, and the gear and the rack mesh.

[0007] Preferably, a plurality of positioning rods are fixedly connected to one side of the movable plate, a second rotating shaft is rotatably connected to one side of the movable plate, a plurality of rotating blades are fixedly connected to one end of the second rotating shaft, and a limit rod is fixedly connected to one side of the movable plate.

[0008] Preferably, the flow meter includes two fixed plates and a flow tube fixedly connected between the two fixed plates. The fixed plates have multiple fixing holes, and a flow meter is fixedly connected to the upper side of the flow tube.

[0009] Preferably, a numerical table is fixedly connected to one side of the water storage tank.

[0010] Preferably, multiple flow calibration knobs are fixedly installed on both sides of the flow meter, and flow calibration valves are fixedly connected to both sides of the flow tube.

[0011] Preferably, an aerogel pad is fixedly connected to one side of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the flow meter needs to be tested, the second motor is started. Through the transmission of gears and racks, the sliding plate and sliding tube slide to automatically clamp and fix the flow meter before subsequent testing. The operation is highly automated, simple to operate, and reduces labor costs.

[0014] 2. Furthermore, this utility model, through the setting of multiple sets of flow meter testing components, utilizes the cooperation of conveyor belt, limit rod and positioning rod. Under the sliding of the moving plate, the limit rod restricts the movement of the fixed seat and flow meter, so that the flow meter and pipeline are relatively stationary, completing the test without stopping the machine, improving the testing efficiency. During the test, the water flow drives the rotating blade to rotate, and while measuring the flow velocity, it detects the defects on the inner wall of the flow pipe. Attached Figure Description

[0020] Reference Figures 1-4 An industrial flow meter testing platform includes a base 1 and a first motor 3 fixedly installed on the base 1. Multiple first rotating shafts 4 are rotatably connected to the upper side of the base 1. The multiple first rotating shafts 4 are connected to a conveyor belt 5 through a common transmission. The output end of the first motor 3 is fixedly connected to one of the first rotating shafts 4. A fixed seat 6 is placed on the upper side of the conveyor belt 5, and a flow meter 2 is placed on the upper side of the fixed seat 6.

[0021] Multiple test components are fixedly connected to the upper side of the base 1, and these test components are arranged sequentially along the conveyor belt 5. Each test component includes two water tanks 10 fixedly connected to the upper side of the base 1. The two water tanks 10 in each test component have the same capacity, but the capacity of the water tanks 10 in different test components is different. A numerical meter 12 is fixedly connected to one side of each water tank 10. The numerical meter 12 displays the amount of water inside the water tank 10 and the time required for all the water inside the water tank 10 to flow out or flow in. First, a float is slidably installed inside the water tank 10. A buoy floats on the water surface inside the water tank 10. A displacement sensor measures the distance between the buoy and the bottom or top of the tank 10, thus determining the water level. Multiplying this water level by the internal bottom area of ​​the tank 10 gives the water volume. This is a real-world method of measuring water level with a buoy. A timer is installed on the outside of the tank 10 and is electrically connected to the controller of the pressure pump 11. The timer starts simultaneously when the pressure pump 11 is activated. When the water level in the tank 10 reaches zero... A displacement sensor installed inside the water storage tank 10 can emit a corresponding electrical signal, which is then transmitted to the controller. The controller automatically shuts down the pressure pump 11 and the timer. At this time, the data on the timer is read, which represents the time required for all water to flow out or flow into the water storage tank 10. All of the above is existing technology. Two water storage tanks 10 are symmetrically installed on both sides of the conveyor belt 5, with one tank full of water and the other empty. A pressure pump 11 is fixedly connected to the upper end of each water storage tank 10. When the pressure pump 11 is working, it can pump water from the storage tank 10... All the water inside the storage tank 10 is drained. A pipe 9 is fixedly connected to one side of the storage tank 10. A sliding tube 8 is slidably connected inside the pipe 9. A moving plate 7 is fixedly connected to one side of the sliding tube 8. A rack 17 is fixedly connected to one side of the moving plate 7. A second motor 21 and a slide 19 are fixedly installed on the upper side of the base 1. The second motor 21 and the slide 19 are directly opposite each other at the lower end of the conveyor belt 5. A gear 20 is fixedly connected to the output end of the second motor 21. A slider 18 is fixedly connected to the lower side of the rack 17. The slider 18 and the slide 19 are slidably connected. The gear 20 and the rack 17 mesh with each other.

[0022] Multiple positioning rods 13 are fixedly connected to one side of the movable plate 7. The positioning rods 13 and the fixing holes 23 are arranged opposite each other, that is, the number and position of the positioning rods 13 and the fixing holes 23 are the same. A second rotating shaft 14 is rotatably connected to one side of the movable plate 7. Multiple rotating blades 15 are fixedly connected to one end of the second rotating shaft 14. During the test, the water flow drives the rotating blades 15 to rotate. The direction of the rotating blades 15 and the direction of the water flow are neither perpendicular nor parallel. Therefore, the flowing water will cause the rotating blades 15 to rotate. The water flow rate of each rotation of the rotating blades 15 is consistent and can be calculated definitely using fluid dynamics. During the process, the water flow rate is determined by the number of rotations of the blade 15. This flow rate is then compared with the water volume on the numerical table 12. If the water flow rate and the water volume on the numerical table 12 are the same under normal circumstances, there is no problem. If the water flow rate and the water volume on the numerical table 12 are different under normal circumstances, it indicates that the rotation of the blade 15 is affected. Since one end of the blade 15 is in close contact with the inner wall of the flow tube 24, the affected rotation of the blade 15 indicates that there is a protrusion on the inner wall of the flow tube 24, that is, there is a defect on the inner wall of the flow tube 24. Thus, the inner wall of the flow tube 24 can be inspected.

[0023] A limiting rod 16 is fixedly connected to one side of the movable plate 7. The sliding of the movable plate 7 drives the limiting rod 16 to move. The limiting rod 16 abuts against the side wall of the flow meter 2, and the limiting rod 16 restricts the movement of the fixed seat 6 and the flow meter 2, so that the flow meter 2 and the pipeline 9 are relatively stationary, ultimately achieving non-stop testing and improving testing efficiency. The flow meter 2 includes two fixed plates 22 and a flow pipe 24 fixedly connected between the two fixed plates 22. Multiple fixing holes 23 are opened on the fixed plates 22. A flow meter 25 is fixedly connected to the upper side of the flow pipe 24, and the flow meter 25 displays the flow rate. The liquid flow rate through the flow tube 24 is calibrated by multiple flow calibration knobs fixedly installed on both sides of the flow meter 25. These knobs can be adjusted after the flow meter 2 is tested to calibrate flow meter test problems caused by some non-structural issues, thereby saving costs and improving the yield rate. Flow calibration valves 26 are fixedly connected to both sides of the flow tube 24, which can also be used for calibration to calibrate flow meter test problems caused by some non-structural issues, thereby saving costs and improving the yield rate. An aerogel gasket is fixedly connected to one side of the moving plate 7 to ensure good sealing when the moving plate 7 and the fixed plate 22 are connected.

[0024] In this invention, when the flow meter needs to be tested, the first motor 3 is started to drive the conveyor belt 5, and the fixed seat 6 containing the flow meter 2 is placed on the conveyor belt 5. Before the second motor 21 is started, that is, in the initial state, the distance between the limit rods 16 is slightly larger than the width of the fixed seat 6. After the second motor 21 is started, the second motor 21 drives the gear 20 to rotate, and the gear 20 drives the rack 17 and the slider 18 to slide along the slide groove 19. The slider 18 drives the moving plate 7 to clamp the flow meter 2. During this process, the moving plate... Driven by the movement of the conveyor belt 5, the lower limit rods 16 move closer to each other, shortening the distance between them until it is less than the length of the fixed seat 6. As the fixed seat 6 moves with the conveyor belt 5, when it comes into contact with the lower limit rods 16, the lower limit rods 16 obstruct its movement, causing the flow meter 2 placed on the fixed seat 6 to stop moving. This results in the flow meter 2 and the pipe 9 remaining relatively stationary, achieving a non-stop test. Meanwhile, the moving plate 7 continues to move. The flow meter 2 is fixed until the positioning rod 13 enters the fixing hole 23. After the clamping and fixing are completed, the pressure pump 11 on the full water tank 10 is started to pump the water in the full water tank 10 into the other water tank 10 through the pipe 9, sliding pipe 8 and flow pipe 24. The amount of water in the full water tank 10 and the time required for all the water in the full water tank 10 to flow out or in are obtained by using the data displayed on the numerical table 12. The flow rate is calculated by dividing the water volume by the time. The calculated flow rate is compared with the data on the flow meter 25. By comparison, if the value is greater than the error value, multiple flow calibration knobs are fixedly installed on both sides of the adjustable flow meter 25 and flow calibration valves 26 are fixedly connected to both sides of the flow tube 24. After calibration, the above operation is repeated. If the obtained data does not change or changes very little (the data here refers to the data on the flow meter 25), it indicates that the flow meter 2 has a structural problem and is a defective product. If the obtained data changes, but is within the allowable error range, and the obtained data is similar to the data on the value table 12, it is a genuine product.
