Description

Technical Field

[0001] The present application relates to the technical field of flowmeters, and in particular to a flowmeter for measuring continuous flow. Background Art

[0002] A flow meter is a precision instrument used to measure the flow of fluids in pipelines. It is widely used in industrial production, energy management, and environmental monitoring. It can monitor the rate at which fluids pass through a specific cross-section in real time, which is crucial to ensuring the stability of the process and optimizing resource allocation.

[0003] Existing flow measurement technologies mainly rely on physical or electronic principles, such as the pressure difference generated when the fluid passes through a specific cross-section, electromagnetic induction, or the time difference in sound wave propagation. For example, a turbine flowmeter calculates the flow rate by detecting the vortex frequency caused by the fluid flow, while an electromagnetic flowmeter uses Faraday's law of electromagnetic induction to determine the flow rate by measuring the induced electromotive force generated when a conductive fluid flows in a magnetic field. These methods each have their own advantages, but they also have limitations, such as dependence on fluid properties and requirements for the installation environment.

[0004] Although existing flow meters can provide relatively accurate flow data, when measuring different liquids through flow meters in actual applications, the connection method between the flow meter and the pipeline often becomes a key factor limiting its performance. At present, most flow meters usually connect two pipelines to the inlet and outlet of the flow meter through threaded connections. However, the sealing performance of this connection method is relatively general, and in an environment with high pressure or large temperature differences, the pipeline connection is easy to loosen. Therefore, during long-term flow measurement, it may lead to an increase in measurement errors. For this reason, the present application provides a flow meter for measuring continuous flow. Summary of the invention

[0005] The purpose of the present application is to provide a flow meter for measuring continuous flow in order to solve the problem that the traditional connection method has poor sealing and the connection is easy to loosen, resulting in increased measurement errors.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A flowmeter for measuring continuous flow, comprising a main shell, a plurality of fixed plates symmetrically fixedly connected inside the main shell, a rotating shaft rotatably connected inside the plurality of fixed plates, a magnetic coupler fixedly connected to the rotating shaft, a plurality of turbine blades evenly fixedly connected to the magnetic coupler, a Hall sensor fixedly connected through the main shell, a display screen fixedly connected to one end of the Hall sensor, the Hall sensor and the display screen electrically connected, a resistance ring symmetrically fixedly connected inside the main shell, an air bag fixedly connected to one side of the resistance ring, threads are provided at both ends of the inner wall of the main shell, two sealing mechanisms are symmetrically installed on the outer wall of the main shell, and a cleaning component is installed on the rotating shaft.

[0007] By adopting the above technical solution, the two pipes are respectively connected to the two ends of the main shell through threads. At this time, they can be connected to the sealing mechanism through an external air pump to effectively improve the sealing effect between the pipe and the main shell, so as to effectively reduce fluid leakage, thereby ensuring that the flow meter can accurately measure the flow rate and avoid resource waste and excessive consumption. At the same time, with the impact flow of the liquid, it will drive multiple turbine blades to rotate. Through the continuous monitoring of the Hall sensor, the flow information can be displayed on the display screen for the operator to view. In addition, when some fluids with crystalline substances are measured for a long time, part of the crystalline substance will adhere to the Hall sensor. At this time, when the liquid drives the turbine blades to rotate and drives the rotating shaft to rotate together, it will also drive the cleaning component to rotate. Through the continuous rotation of the cleaning component, the Hall sensor will be cleaned cyclically, so as to keep the Hall sensor clean and tidy, which greatly improves the measurement accuracy of the Hall sensor.

[0008] Furthermore, the sealing mechanism includes two fixed blocks symmetrically fixedly connected at both ends of the outer wall of the main shell, one side of the two fixed blocks is penetrated by a connecting pipe, the end of the connecting pipe away from the fixed block is fixedly connected to the airbag, and the interior of the two fixed blocks is slidably connected with a sealing plate, one end of one of the fixed blocks is fixedly connected to an air inlet, and one end of the other fixed block is fixedly connected to an exhaust port, both the air inlet and the exhaust port are provided with a one-way valve, one side of the sealing plate is provided with a fastener, and one side of the sealing plate is provided with a limit piece.

[0009] By adopting the above technical solution, the interior of the fixed block is continuously inflated through the air inlet, thereby driving the airbag to expand, effectively improving the sealing effect between the pipeline and the main shell, thereby effectively reducing fluid leakage, thereby ensuring that the flow meter can accurately measure the flow rate and avoid waste of resources and excessive consumption.

[0011] By adopting the above technical solution, as the sealing plate moves, the moving column will be driven to slide, thereby pushing the clamping plate close to the outer wall of the pipe.

[0014] Furthermore, the limit member includes two support blocks symmetrically fixedly connected to one side of the sealing plate, one side of the two support blocks is provided with a groove, the interior of the groove is fixedly connected with a spring 2, the interior of the groove is slidably connected with a locking block, one end of the spring 2 is fixedly connected to one end of the locking block, the end of the locking block away from the spring 2 is arc-shaped, and the inner wall of the fixed block is symmetrically provided with locking grooves, and the shape and size of the locking grooves are consistent with the arc-shaped end of the locking block.

[0015] By adopting the above technical solution, when the sealing plate pushes the movable column to move, the position of the locking block will be pushed to one side of the locking groove. At this time, according to the mutual snap-fitting cooperation between the locking block and the locking groove, the position of the sealing plate can be limited and locked, so as to fix the position of the clamping plate and the rubber pad.

[0016] Furthermore, the cleaning component comprises a fixed column fixedly connected to the rotating shaft, a sliding block is slidably connected inside the fixed column, a cleaning brush is arranged at one end of the sliding block, and a connecting piece is arranged inside the sliding block.

[0017] By adopting the above technical solution, when the liquid drives the turbine blades to rotate and drives the rotating shaft to rotate, it will also drive the cleaning brush to rotate, so that the Hall sensor will be cleaned cyclically.

[0018] Furthermore, one end of the sliding block away from the cleaning brush is fixedly connected to a magnetic block 1, and the interior of the fixed column is fixedly connected to a magnetic block 2, and the opposite surfaces of the magnetic block 1 and the magnetic block 2 have the same magnetic poles.

[0019] By adopting the above technical solution, since the opposite magnetic poles of magnetic block 1 and magnetic block 2 are the same, magnetic block 1 and magnetic block 2 will repel each other, so that the sliding block can always push the cleaning brush to fit and contact the inner wall of the main shell.

At this time, the clamping connection of the cleaning brush can be released to pull out the cleaning brush for replacement, which greatly improves the replacement efficiency of the cleaning brush.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. The present application is provided with a sealing mechanism and fasteners, and the interior of the fixed block is continuously inflated through the air inlet, thereby driving the airbag to expand, effectively improving the sealing effect between the pipeline and the main shell, thereby effectively reducing fluid leakage, thereby ensuring that the flow meter can accurately measure the flow rate, avoiding waste and excessive consumption of resources, and at the same time avoiding safety accidents and production losses caused by leakage, and with the impact of the gas, the clamping plate will be driven to move together through the sealing plate, so as to clamp and stabilize the outer wall of the pipeline, so that the pipeline can remain stable during the process of conveying liquid, thereby reducing the interference of external vibration or noise on the measurement results of the flow meter, thereby improving the accuracy of the measurement.

[0023] 2. In the present application, a limiting member is provided. When the sealing plate pushes the movable column to move, it also pushes the supporting block to move together, thereby driving the locking block to move to one side of the locking groove. According to the mutual snap-fitting cooperation between the locking block and the locking groove, the position of the sealing plate can be limited and locked, thereby fixing the position of the clamping plate and the rubber pad and improving the clamping stability of the clamping plate.

The end of the connecting pipe 11 away from the fixed block 10 is fixedly connected to the airbag 9. The inside of the two fixed blocks 10 is slidably connected with a sealing plate 12, one end of one of the fixed blocks 10 is fixedly connected to an air inlet 13, and one end of the other fixed block 10 is fixedly connected to an exhaust port 14, and one-way valves are arranged inside the air inlet 13 and the exhaust port 14, one side of the sealing plate 12 is provided with a fastener, and one side of the sealing plate 12 is provided with a limit member.

[0034] When in use, first connect the two pipes to the two ends of the main shell 1 through threads, and ensure that the inlet and outlet directions of the water flow in the pipe are correct. At this time, the external air pump can be connected to the air inlet 13, and then the interior of the fixed block 10 is inflated. At this time, the gas will gradually enter the interior of the airbag 9 through the connecting pipe 11 on one side, so that the airbag 9 is gradually inflated and expanded, and the inflated airbag 9 will gradually fit with one side of the resistance ring 8 and one end of the pipe. The expansion of the airbag 9 will effectively improve the sealing effect between the pipe and the main shell 1, thereby effectively reducing fluid leakage, thereby ensuring that the flow meter can accurately measure the flow rate, avoiding waste and excessive consumption of resources, and avoiding safety accidents and production accidents caused by leakage. Loss, while the gas gradually enters the fixed block 10 to inflate the airbag 9, according to the impact and pressure of the gas, the sealing plate 12 will be pushed to move inside the fixed block 10, so that the movement of the sealing plate 12 will drive the fasteners and limiters on one side to operate. Through the cooperation of the fasteners and limiters, the outer wall of the pipeline can be clamped and stabilized in the process of improving the sealing performance, so that the pipeline can remain stable during the process of transporting liquid, thereby reducing the interference of external vibration or noise on the flow meter measurement results, thereby improving the measurement accuracy, and reducing the potential damage of the pipeline caused by vibration or movement, extending the service life of the flow meter, and reducing maintenance costs and downtime; Secondly, when the pipe connections at both ends are stable, the transmission liquid can be flowed inside the main shell 1. As the liquid flows with impact, multiple turbine blades 5 will be driven to rotate, and as the turbine blades 5 rotate, the magnetic coupler 4 will be displaced. At this time, the Hall sensor 6 can capture the changes of the turbine blades 5 and the magnetic coupler 4 in real time and transmit them to the display screen 7 through electrical signals. At this time, the corresponding flow value will be automatically calculated by the pre-set formula of the system, and the result will be finally displayed on the display screen 7 for the operator to view, thereby realizing the measurement of continuous flow, while being both economical and practical. In addition, when some fluids with crystalline substances are measured for a long time, part of the crystalline substance will adhere to the Hall sensor 6. At this time, when the liquid drives the turbine blades 5 to rotate and drives the rotating shaft 3 to rotate together, it will also drive the cleaning component to rotate. Through the continuously rotating cleaning component, the Hall sensor 6 will be cleaned cyclically, thereby keeping the Hall sensor 6 clean and tidy, greatly improving the measurement accuracy of the Hall sensor 6.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The fastener includes a moving column 15 that passes through and is slidably connected to one end of the fixed block 10, one end of the moving column 15 is fixedly connected to one side of the sealing plate 12, the end of the moving column 15 away from the sealing plate 12 is fixedly connected to a clamping plate 16, the inner wall of the clamping plate 16 is fixedly connected to a rubber pad 17, and a spring 18 is fixedly connected to the side of the sealing plate 12 away from the moving column 15, and the end of the spring 18 away from the sealing plate 12 is fixedly connected to the inner wall of the fixed block 10.

[0036] During use, as the sealing plate 12 moves, the moving column 15 will be driven to slide, thereby pushing the clamping plate 16 to approach the outer wall of the pipe until the rubber pad 17 on one side of the clamping plate 16 is tightly fitted with the outer wall of the pipe. Then, the inflation of the interior of the fixed block 10 can be stopped. At this time, the one-way valves in the air inlet 13 and the exhaust port 14 can be closed to prevent gas leakage. At this time, the outer wall of the pipe can be clamped and stabilized by the tight clamping of the two clamping plates 16 and the rubber pad 17, so that the pipe can remain stable during the process of conveying liquid, thereby reducing the interference of external vibration or noise on the measurement results of the flow meter, thereby improving the measurement accuracy.

[0037] Reference Figure 1 , Figure 3 and Figure 4The limiter includes two support blocks 19 symmetrically fixedly connected to one side of the sealing plate 12, one side of the two support blocks 19 is provided with a groove 20, a spring 21 is fixedly connected inside the groove 20, a locking block 22 is slidably connected inside the groove 20, one end of the spring 21 is fixedly connected to one end of the locking block 22, and the end of the locking block 22 away from the spring 21 is arc-shaped, and the inner wall of the fixed block 10 is symmetrically provided with a locking groove 23, and the shape and size of the locking groove 23 are consistent with the arc-shaped end of the locking block 22.

[0038] When in use, when the sealing plate 12 pushes the moving column 15 to move, it will also push the supporting block 19 to move together. At this time, with the squeezing of the inner wall of the fixing block 10, the locking block 22 will enter the interior of the groove 20 and squeeze the spring 21 to contract. When the clamping plate 16 and the rubber pad 17 are completely fitted and clamped with the inner wall of the pipe, the position of the locking block 22 will move to one side of the locking groove 23. At this time, according to the rebound of the spring 21, the locking block 22 will be pushed into the interior of the locking groove 23. According to the mutual engagement of the locking block 22 and the locking groove 23, the position of the sealing plate 12 can be limited and locked, so as to clamp The positions of the plate 16 and the rubber pad 17 are fixed, and when the flow measurement is completed, the one-way valve in the exhaust port 14 can be opened to discharge the gas inside the airbag 9 and the fixed block 10 to the outside through the exhaust port 14. At this time, the interior of the fixed block 10 will gradually lose air pressure and lose its resistance to the sealing plate 12. Therefore, according to the rebound of the spring 18, the sealing plate 12 will be driven to reset, and according to the guidance of the arc-shaped end of the locking block 22, the locking block 22 is pulled out from the locking groove 23 to release the limit lock, so that the sealing plate 12 can be reset while driving the clamping plate 16 and the rubber pad 17 to reset, waiting for the next use.

[0040] When in use, since the magnetic poles of the opposite surfaces of magnetic block 1 27 and magnetic block 2 28 are the same, magnetic block 1 27 and magnetic block 2 28 will repel each other, so that the sliding block 25 can always push the cleaning brush 26 to fit and contact the inner wall of the main shell 1. When the liquid drives the turbine blades 5 to rotate and drives the rotating shaft 3 to rotate together, it will also drive the cleaning brush 26 to rotate. Through the continuous rotation of the cleaning brush 26, the Hall sensor 6 will be cleaned cyclically, thereby keeping the Hall sensor 6 clean and tidy, and greatly improving the measurement accuracy of the Hall sensor 6.

[0041] Reference Figure 2 and Figure 5 The connecting member includes a slide groove 29 opened at one end of the sliding block 25, a U-shaped block 30 is slidably connected inside the slide groove 29, a spring three 31 is fixedly connected to the inner wall of the slide groove 29, the other end of the spring three 31 is fixedly connected to one side of the U-shaped block 30, a limiting groove 32 is opened on one side of the cleaning brush 26, and one end of the U-shaped block 30 is slidably connected in the limiting groove 32.

[0042] During use, if the cleaning brush 26 needs to be replaced, the U-shaped block 30 can be pressed to move into the slide groove 29 and squeeze the spring three 31 to contract. As the U-shaped block 30 moves, the other end of the U-shaped block 30 also moves inside the limiting groove 32, so that one end of the U-shaped block 30 is separated from the limiting groove 32. At this time, the clamping of the cleaning brush 26 can be released, and the cleaning brush 26 can be pulled out and replaced, which greatly improves the replacement efficiency of the cleaning brush 26.

[0043] The implementation principle of a flow meter for measuring continuous flow in the present embodiment is as follows: when in use, firstly, the two pipes are respectively connected to the two ends of the main shell 1 through threads, and it is ensured that the inlet and outlet directions of the water flow in the pipes are correct. At this time, the air pump can be connected to the air inlet 13 through an external air pump, and then the interior of the fixed block 10 is inflated. At this time, the gas will gradually enter the interior of the airbag 9 through the connecting pipe 11 on one side, so that the airbag 9 is gradually inflated and expanded, and the inflated airbag 9 will gradually fit with one side of the resistance ring 8 and one end of the pipe. The expansion of the airbag 9 will effectively improve the sealing effect between the pipe and the main shell 1, thereby effectively reducing fluid leakage, thereby ensuring that the flowmeter can accurately measure the flow, avoid waste and excessive consumption of resources, and at the same time avoid safety accidents and production losses caused by leakage. When the gas gradually enters the interior of the fixed block 10 to inflate the airbag 9 At the same time, according to the impact and pressure of the gas, the sealing plate 12 will be pushed to move inside the fixed block 10. As the sealing plate 12 moves, the moving column 15 will be driven to slide, thereby pushing the clamping plate 16 to approach the outer wall of the pipe until the rubber pad 17 on one side of the clamping plate 16 is tightly fitted with the outer wall of the pipe. Then, the inflation inside the fixed block 10 can be stopped. At this time, the one-way valves in the air inlet 13 and the exhaust port 14 can be closed to prevent gas leakage. At this time, the outer wall of the pipe can be clamped and stabilized by the tight clamping of the two clamping plates 16 and the rubber pad 17, so that the pipe can remain stable during the process of conveying liquid, thereby reducing the interference of external vibration or noise on the measurement results of the flow meter, thereby improving the measurement accuracy, and reducing the potential damage to the pipe due to vibration or movement, extending the service life of the flow meter, and reducing maintenance costs and downtime; In addition, when the sealing plate 12 pushes the moving column 15 to move, it will also push the supporting block 19 to move together. At this time, with the squeezing of the inner wall of the fixing block 10, the locking block 22 will enter the interior of the groove 20 and squeeze the spring 21 to contract. When the clamping plate 16 and the rubber pad 17 are completely fitted and clamped with the inner wall of the pipe, the position of the locking block 22 will move to one side of the locking groove 23. At this time, according to the rebound of the spring 21, the locking block 22 will be pushed into the interior of the locking groove 23. According to the mutual engagement of the locking block 22 and the locking groove 23, the position of the sealing plate 12 can be limited and locked, so as to fix the clamping plate The positions of the airbag 9 and the rubber pad 17 are fixed, and when the flow measurement is completed, the one-way valve in the exhaust port 14 can be opened to discharge the gas in the airbag 9 and the fixed block 10 to the outside through the exhaust port 14. At this time, the interior of the fixed block 10 will gradually lose air pressure and lose the resistance to the sealing plate 12. Therefore, according to the rebound of the spring 18, the sealing plate 12 will be driven to reset, and according to the guidance of the arc-shaped end of the locking block 22, the locking block 22 will be pulled out from the locking groove 23 to release the limit lock, so that the sealing plate 12 can be reset while driving the clamping plate 16 and the rubber pad 17 to reset, waiting for the next use; Secondly, when the pipe connections at both ends are stable, the transmission liquid can be flowed inside the main shell 1. As the liquid flows with impact, multiple turbine blades 5 will be driven to rotate, and as the turbine blades 5 rotate, the magnetic coupler 4 will be driven to move together. At this time, the Hall sensor 6 can capture the changes of the turbine blades 5 and the magnetic coupler 4 in real time, and transmit them to the display screen 7 through electrical signals. At this time, the corresponding flow value will be automatically calculated by the formula pre-set by the system, and the result will be finally displayed on the display screen 7 for the operator to view, thereby realizing the measurement of continuous flow, while being both economical and practical. In addition, when some fluids with crystalline substances are measured for a long time, part of the crystalline substances will adhere to the Hall sensor 6. At this time, because the opposite magnetic poles of the magnetic block 1 27 and the magnetic block 2 28 are the same, the magnetic block 1 27 and the magnetic block 2 28 will be displaced. 8 repel each other, so that the sliding block 25 can always push the cleaning brush 26 to fit and contact with the inner wall of the main shell 1. When the liquid drives the turbine blades 5 to rotate and drives the rotating shaft 3 to rotate together, it will also drive the cleaning brush 26 to rotate. Through the continuously rotating cleaning brush 26, the Hall sensor 6 will be cleaned cyclically, so as to keep the Hall sensor 6 clean and tidy, which greatly improves the measurement accuracy of the Hall sensor 6. If the cleaning brush 26 needs to be replaced, the U-shaped block 30 can be pressed to move into the slide groove 29, and the spring three 31 can be squeezed to contract. As the U-shaped block 30 moves, the other end of the U-shaped block 30 will also move inside the limiting groove 32, so that one end of the U-shaped block 30 is separated from the limiting groove 32. At this time, the clamping of the cleaning brush 26 can be released to pull out the cleaning brush 26 for replacement, which greatly improves the replacement efficiency of the cleaning brush 26.
