Traditional gas flow monitoring devices have some common problems in practical applications. For example, the monitoring end is easily affected by impurities. Whether it is an ultrasonic transceiver module, a temperature sensor or a turbine, impurities will cause the gas flow meter to decrease in accuracy. Moreover, some devices currently lack an effective impurity filtering and cleaning mechanism, and cannot guarantee long-term stable filtering effects. Frequent manual intervention is required to clean impurities, which not only increases labor costs, but may also affect the accuracy of monitoring and the normal operation of the device due to untimely cleaning.

The term "more than two" includes two or more than two situations.

[0034] See also Figures 1 to 11 As shown, the present application provides a gas flow monitoring device based on the Internet of Things, including: a shell 10, a gas flow meter 20, a steering mechanism 30 and a power mechanism 40. The shell 10 is provided with an air inlet port 11 and an exhaust port 12, which are respectively used to connect with an external air supply pipeline. The shell 10 is also provided with an impurity discharge port 13, and the function of the impurity discharge port 13 is to discharge impurities to the outside of the equipment; the gas flow meter 20 is fixedly mounted on the shell 10, and the gas flow meter 20 can adopt an ultrasonic flow meter, a thermal gas flow meter 20 and a turbine gas flow meter 20, and the present technical solution does not limit this. The gas flow meter 20 includes a monitoring end 22. When the gas flow meter 20 is an ultrasonic gas flow meter When the gas flow meter 20 is a thermal gas flow meter 20, the monitoring end 22 is an ultrasonic transmitting and receiving module. When the gas flow meter 20 is a thermal gas flow meter 20, the monitoring end 22 can be a group of temperature sensors. When the gas flow meter 20 is a turbine gas flow meter 20, the monitoring end 22 can be a mechanically rotating turbine. The monitoring end 22 is located in the middle of the inner cavity of the shell 10 and is mounted on any of the aforementioned gas flow meters 20. The gas flow meter 20 has a built-in Internet of Things module to provide a remote information transmission function; the steering mechanism 30 is rotatably arranged in the inner cavity of the shell 10, and the steering mechanism 30 is clamped in the shell 10; the power mechanism 40 is arranged at the bottom end of the shell 10 and is connected to the steering mechanism 30 to provide rotational kinetic energy for the power mechanism 40.

[0035] Among them, the ultrasonic transceiver module, temperature sensor and turbine arranged in the monitoring end 22 are easily affected by impurities, causing the accuracy of the gas flow meter 20 to decrease. In this regard, the steering mechanism 30 also includes an air inlet 32 ​​and an exhaust hole 33. A filter component 34 is also arranged in the air inlet 32. In the first state, the filtering performance of the filter component 34 is in a good state, and the position of the filter component 34 corresponds to the position of the air inlet port 11. In the second state, the filtering performance of the filter component 34 is insufficient, and the filter component 34 turns to the exhaust port 13 and then stays at the position where it was in the first state.

[0036] Specifically, in the present gas flow monitoring device based on the Internet of Things, the housing 10 serves as the overall supporting structure, and its inlet port 11 and exhaust port 12 are used to connect to an external gas pipeline to ensure the inlet and outlet of gas, and the impurity discharge port 13 is used to discharge impurities. The gas flow meter 20 is fixed on the housing 10, and its monitoring end 22 is located in the middle of the inner cavity of the housing 10 to accurately monitor the gas flow, and the built-in Internet of Things module facilitates data transmission.

[0037] Among them, the steering mechanism 30 is rotatably arranged in the inner cavity of the shell 10 and is clamped in the shell 10. Its air inlet 32 ​​and the exhaust hole 33 are used for the circulation of gas, so that the gas can enter the interior of the steering mechanism 30, thereby contacting the monitoring end 22 of the gas flow meter 20 to achieve measurement. The filter component 34 in the air inlet 32 ​​corresponds to the air inlet port 11 in the first state, that is, in the working state, and can effectively filter the impurities in the gas entering. As the working time of the filter component 34 increases, too many impurities are accumulated on its surface, which will seriously affect the flow of the airflow and the monitoring effect of the flow rate. Therefore, when excessive impurities are accumulated on the surface of the filter component 34, the filter component 34 is regarded as the second state. When the filtering performance of the filter component 34 is insufficient and enters the second state, the airflow is not smooth, and pressure is applied to the filter component 34. The filter component 34 contacts the restriction of the shell 10 on it. The overall filter component 34 and the steering mechanism 30 rotate under the action of the power mechanism 40, and turn to the impurity discharge port 13 to discharge the impurities and then return to the position in the first state to ensure the continuity of the filtering effect. The power mechanism 40 is disposed at the bottom end of the housing 10 and connected to the steering mechanism 30 to provide power for the rotation of the steering mechanism 30 .

[0038] During operation, gas enters from the air inlet port 11, is filtered by the filter component 34 in good condition in the air inlet hole 32 of the steering mechanism 30, and then enters the inner cavity of the shell 10. The gas flowmeter 20 monitors the flow rate, and then the gas is discharged through the exhaust hole 33 of the steering mechanism 30 and the exhaust port 12. When the filter component 34 needs to be cleaned of impurities, the power mechanism 40 drives the steering mechanism 30 to rotate to the impurity discharge port 13 to complete the impurity discharge and then reset. The device can accurately monitor the gas flow, effectively filter impurities, and automatically clean the filter component 34, thereby ensuring stable operation of the device.

[0039] like Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, in some examples, further, the steering mechanism 30 also includes an assembly cavity 31, which is opened in the middle of the steering mechanism 30; it is used to assemble the gas flow meter 20, and the air inlet hole 32 and the exhaust hole 33 are respectively connected to the assembly cavity 31, and the air inlet hole 32 and the exhaust hole 33 are not in the same straight line.

[0040] In this example, the assembly cavity 31 in the middle of the steering mechanism 30 is used to assemble the gas flow meter 20 to provide a stable installation position for it; the air inlet 32 ​​and the exhaust hole 33 are respectively connected to the assembly cavity 31, so that the gas can enter the surrounding area of ​​the assembly cavity 31 through the air inlet 32, and then flow out through the exhaust hole 33; the air inlet 32 ​​and the exhaust hole 33 are not arranged in the same straight line, so that the air inlet 32 ​​and the exhaust hole 33 can form the exhaust hole 33 to connect to the air inlet port 11 during the rotation process, and at the same time ensure that the air inlet 32 ​​is in an exposed state. When working, the airflow can enter the steering mechanism 30 through the exhaust hole 33, and then be discharged to the outside from the exposed air inlet 32. In this process, the airflow acts in reverse on the filter component 34, thereby realizing an automated and efficient reverse cleaning mechanism, utilizing the flow path of the gas in the device to achieve an efficient self-cleaning effect, and always ensuring that the airflow in contact with the monitoring end 22 of the gas flow meter 20 is a clean airflow to avoid the occurrence of impurities attached to affect the monitoring accuracy.

[0041] like Figures 6 to 11 As shown, in some examples, further, the filter component 34 includes: an active chamber 341, a frame 342, a filter screen 343, a torque portion 344 and a limiting plug rod 345, the active chamber 341 is opened in the air inlet 32, and the active chamber 341 is arranged in a fan shape; one end of the frame 342 is rotatably arranged in the active chamber 341, and the frame 342 rotates close to or away from the center direction of the shell 10; the filter screen 343 is fixedly arranged in the frame 342 and corresponds to the position of the air inlet port 11; the torque portion 344 is fixedly arranged, and the torque portion 344 is also connected to the rotating shaft of the frame 342 to provide the filter screen 343 with a torque that always turns to the air inlet direction; the limiting plug rod 345 is fixedly arranged on the other end of the frame 342 away from its own rotating end, and the other end of the limiting plug rod 345 extends to the outside of the steering mechanism 30 and is clamped in the shell 10.

[0042] In this example, the fan-shaped active cavity 341 provides space for the rotation of the frame 342, and is opened in the air inlet 32 ​​so that the entire filtering process can be completed in the air intake link; one end of the frame 342 is rotatably arranged in the active cavity 341, and when the filtering performance of the filter 343 deteriorates, that is, the air permeability is not high, the frame 342 is driven to rotate in a direction close to or away from the center of the shell 10; the filter 343 is a component for filtering impurities and directly filters the incoming gas; the torque part 344 is fixedly arranged and connected to the rotating shaft of the frame 342, and its function is to continuously provide the filter 343 with a torque to turn in the air intake direction, to ensure that the filter 343 is always in a position to filter the intake air in the first state; the limit rod 345 is fixed to the frame 342 away from the rotation The end portion of the end extends to the outside of the steering mechanism 30 and is clamped in the shell 10, which is used to limit the rotation of the frame 342 and the overall steering mechanism 30. That is to say, only when the air permeability of the filter 343 deteriorates, the frame 342 and the limiting plug 345 are rotated under the action of air pressure, thereby releasing the position restriction of the limiting plug 345 by the shell 10, and driving the filter 343 and the frame 342 to continue rotating for one circle under the action of the power mechanism 40; the torque portion 344 makes the filter 343 return to the normal filtering position, and then the overall power mechanism 40 including the filter 343 and the limiting plug 345 returns to the working position of the first state again, thereby ensuring the long-term effectiveness and stability of the filtering function, thereby improving the performance of the entire device.

[0043] like Fig. 9 As shown in the figure, in some examples, further, the shell 10 is also provided with: a limit groove 15, a vibration groove 16 and a steering groove 17. The limit groove 15 is opened on the inner wall of the shell 10, the limit groove 15 is arc-shaped, and is concentric with the rotation axis of the frame 342, and the limit plug 345 can be movably inserted in the limit groove 15; the vibration groove 16 is connected to the limit groove 15, and is located on the side of the limit groove 15 away from the exhaust port 12, and the limit plug 345 can be movably inserted in the limit groove 15; the steering groove 17 is arc-shaped, and the two ends of the steering groove 17 are respectively connected to the limit groove 15 and the other end of the vibration groove 16, the middle part of the steering groove 17 is concentric with the steering mechanism 30, and the limit plug 345 can be movably inserted in the limit groove 15.

[0044] In this example, the limit groove 15 on the shell 10 is arc-shaped and concentric with the rotation axis of the frame 342, so that the limit rod 345 can move in the limit groove 15 on the shell 10 while following the rotation of the frame 342. The opening direction of the limit groove 15 can prevent the limit rod 345 and the overall steering mechanism 30 from rotating, ensuring that the filter component 34 can only rotate when it is in the second state; the vibration groove 16 is connected to the limit groove 15 and is located on the side away from the exhaust port 12. When the filter component 34 is in the second state, the limit rod 345 first breaks away from the restriction of the limit groove 15 and then enters the vibration groove 16. The vibration groove 16 can guide the limit rod 345 to move, causing the frame 342 to vibrate, thereby assisting the impurities to fall off in advance; then the limit rod 345 enters the steering In the groove 17, the turning groove 17 is an arc-shaped two ends respectively connected to the limit groove 15 and the other end of the vibration groove 16 to form a closed through groove. The middle part of the turning groove 17 is concentric with the steering mechanism 30. Therefore, the limit rod 345 and the overall filter 343 can have a faster speed during the rotation process and generate centrifugal force, so that the impurities that have fallen off are thrown out of the outside of the shell 10, and then enter the limit groove 15 through the turning groove 17 to perform another air filtering operation. Therefore, the overall closed slot forms a complete path for the limit rod 345 from the limit groove 15 to the vibration groove 16 and then returns through the turning groove 17, ensuring the rotation continuity of the frame 342 during the entire impurity removal process; achieving effective impurity removal, improving the device's ability to handle impurities, and ensuring the long-term stable operation of the gas flow monitoring device.

[0045] like Figure 2 , Figure 6 and Figure 8 As shown, in some examples, further, the impurity removal port 13 is strip-shaped, and an impurity removal area 14 is further provided in the impurity removal port 13 , and the angle between the impurity removal area 14 and the air inlet port 11 is equal to the angle between the air inlet hole 32 and the air exhaust hole 33 .

[0046] In this example, it should be noted that the impurity discharge port 13 is strip-shaped, forming a large impurity discharge area to ensure that the filter screen 343 has sufficient impurity discharge space during the rotation process; the impact impurity discharge area 14 plays an important role, because the angle between it and the air inlet port 11 is equal to the angle between the air inlet hole 32 and the exhaust hole 33. When the impurities in the filter component 34 are saturated and turned to the impurity discharge port 13 with the overall steering mechanism 30, the gas entering from the air inlet direction can impact the impact impurity discharge area 14 through the channel direction formed by the exhaust hole 33, the assembly cavity 31 and the air inlet hole 32. 4. During the rotation of the steering mechanism 30, one of the stages is to close the air inlet port 11, then the pressure in the external air intake pipe will increase, and then the exhaust hole 33 will be connected to the air inlet port 11. The pressurized airflow can produce a strong impact force on the impurities, and the impurities attached to the filter component 34 will be more effectively peeled off and discharged through the impurity discharge port 13; therefore, the setting of this example can enhance the impurity removal effect, reduce impurity residues, and ensure the filtering performance of the filter component 34, thereby maintaining the stable operation of the entire gas flow monitoring device and improving the reliability and service life of the device.

[0047] like Fig. 9 and Fig.11 As shown, in some examples, further, the entire or a portion of the vibration groove 16 is located on the inner wall of the housing 10 between the impingement and impurity removal area 14 and the air intake port 11 .

[0048] It can be understood that a part of the vibration groove 16 or the entire vibration groove 16 is located on the inner wall of the shell 10 between the impact impurity removal area 14 and the air inlet port 11; when the filter assembly 34 is in the impurity removal process, the limiting plug 345 moves in the vibration groove 16, driving the frame 342 and the filter screen 343 to vibrate, and then the airflow entering from the air inlet port 11 is used to forcefully blow the impurities out of the impact impurity removal area 14. Therefore, the limiting plug 345 passing through the vibration groove 16 drives the frame 342 to produce stronger vibrations; this vibration helps to loosen the impurities on the filter screen 343 and the filter assembly 34, and under the further action of the airflow in the impact impurity removal area 14, the impurities are more easily peeled off and discharged.

[0049] like Figure 3 , Figure 4 and Fig.10As shown, in some examples, further, the power mechanism 40 includes: a positioning base plate 41, a ratchet ring 42, a center column 43, a torsion spring 44, a pawl 45 and a rotating shell 46, the positioning base plate 41 is fixedly arranged at the bottom end of the shell 10; the ratchet ring 42 is fixedly arranged on the inner wall of the positioning base plate 41; the center column 43 is fixedly connected to the middle of the bottom end of the steering mechanism 30 and is located in the positioning base plate 41; the rotating shell 46 is rotatably mounted on the outside of the center column 43; the torsion spring 44 is arranged in the inner cavity of the rotating shell 46, the inner end is fixedly connected to the center column 43, and the outer end is fixedly connected to the rotating shell 46; the pawl 45 is elastically rotatably arranged on the outer wall of the rotating shell 46, and cooperates with the ratchet ring 42.

[0050] In the power mechanism 40 provided in this example, the positioning base plate 41 serves as the fixed foundation of the entire power mechanism 40; the ratchet ring 42 is fixed to the inner wall of the positioning base plate 41, and cooperates with the pawl 45 to limit the rotation direction; the center column 43 is fixed to the middle of the bottom end of the steering mechanism 30 and is located in the positioning base plate 41, and plays the role of connecting the steering mechanism 30 and the ratchet ring 42; the rotating shell 46 is rotatably sleeved on the outside of the center column 43, and is a key component for power transmission. The staff can directly apply manual force to drive the rotating shell 46 to rotate; the torsion spring 44 is arranged in the inner cavity of the rotating shell 46, and its function is to store and release energy, and to provide power for the steering mechanism 30 and The rotation of the filter 343 provides torque; the pawl 45 is elastically rotatably arranged on the outer wall of the rotating shell 46 and cooperates with the ratchet ring 42. When the steering mechanism 30 needs to be rotated, the rotating shell 46 is manually driven to rotate. The pawl 45 overcomes the elastic force and the action of the ratchet ring 42 under the action of the rotating force of the rotating shell 46, so that the overall rotating shell 46 can only rotate in one direction. After rotation, the torsion spring 44 twists and deforms to accumulate force. During the process of accumulating force again, it can provide torque to cause the steering mechanism 30 to rotate multiple times, thereby realizing automatic steering and other actions when the filter component 34 is in an impurity saturated state, ensuring that the filter component 34 can quickly rotate and discharge impurities when impurities need to be discharged.

[0051] In some examples, further, a torsion sensor (not shown) is provided between the central column 43 and the torsion spring 44, and the torsion sensor is also connected to the Internet of Things module.

[0052] In this example, the torque sensor is arranged between the center column 43 and the torsion spring 44 and connected to the Internet of Things module. The function of the torque sensor is to detect the torque borne by the torsion spring 44 to notify the staff to come to wind up the spring when necessary, so that the power mechanism 40 always stores kinetic energy to rotate the steering mechanism 30. Through the Internet of Things module, it is also possible to know whether the rotation resistance of the rotating shell 46 is abnormal, etc., which helps to discover potential faults in advance, ensure the normal operation of the steering mechanism 30 in the entire gas flow monitoring device, and improve the maintenance efficiency and operation stability of the equipment.

[0053] In some examples, further, the power mechanism 40 also includes a motor (not shown), and the output end of the motor is transmission-connected to the rotating shell 46 to realize automatic rotation of the rotating shell 46.

[0054] In this example, a motor is further provided as a newly added component of the power mechanism 40, and its output end is transmission-connected to the rotating shell 46; the convenience of using the device can be further improved. For example, when the device is installed in a remote location, there is no need for manual maintenance equipment to perform winding and power storage operations, and the rotating shell 46 can be driven to rotate by starting the motor; the automation level and efficiency of the entire device operation are improved, and the need for manual intervention is reduced.

[0055] like Figure 1 , Figure 2 and Figure 5 As shown, in some examples, further, a top plate 21 is fixedly provided on the outer wall of the gas flow meter 20 , and the top plate 21 is detachably buckled on the top of the shell 10 .

[0056] It can be understood that the top plate 21 is fixed on the outer wall of the gas flow meter 20 and is detachably fastened to the top of the shell 10; the main function of the top plate 21 is to provide dual functions of protection and fixation for the gas flow meter 20; on the one hand, it can prevent external objects from directly contacting the monitoring end 22 components of the gas flow meter 20 to avoid physical damage thereto; on the other hand, by being fastened to the top of the shell 10 and not rotating synchronously with the steering mechanism 30, the position of the gas flow meter 20 in the shell 10 is further stabilized to prevent displacement, which is also more conducive to the replacement and maintenance of the flow meter.

[0057] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
