Description

Technical Field

[0001] This invention relates to the field of gas transport and fluid mixing control technology, specifically to a hydrogen-rich mixed gas transport pipeline system with active flow disturbance function, and more particularly to a multi-stage flow field regulation pipeline structure system that can achieve coordinated switching between pneumatic drive and active drive, and has both mixing enhancement and steady flow transport functions. Background Technology

[0002] Hydrogen-rich gas mixtures have significant applications in industrial combustion, energy supply, and gas reaction systems. However, due to the low density and rapid diffusion of hydrogen, which easily leads to stratification and localized enrichment, problems such as uneven component distribution, low mixing efficiency, and unstable flow fields can easily occur during transportation and mixing, thus affecting combustion stability and energy utilization efficiency in subsequent use. Therefore, during the transportation of hydrogen-rich gas mixtures, it is usually necessary to thoroughly mix different gases and maintain a stable transportation state.

[0003] In existing technologies, simple mixing chambers or single turbulence structures are typically used to mix gases. However, such structures generally suffer from problems such as reliance on a single flow driver for the mixing process, unadjustable turbulence intensity, and weak flow field control capabilities. This leads to localized uneven mixing or turbulent flow even under high flow rates or complex operating conditions. Furthermore, some devices rely solely on external power sources to drive the mixing mechanism, resulting in high energy consumption, complex structures, and insufficient adaptability to various operating conditions.

[0004] In addition, existing conveying systems often lack effective flow transition and shaping structures between the mixing and conveying stages. This makes it easy for sudden changes in flow velocity or local eddies to occur when the gas enters the conveying pipeline directly after mixing, thereby reducing conveying stability and increasing the uncertainty and energy loss of system operation.

[0005] Therefore, how to achieve efficient mixing, controllable turbulence, and stable flow delivery of hydrogen-rich gas mixtures during transportation while reducing external energy consumption, and how to improve the system's adaptability to different operating conditions, have become urgent technical problems to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hydrogen-rich mixed gas transportation pipeline system with active flow disturbance function.

[0007] The objective of this invention is achieved as follows: A hydrogen-rich mixed gas delivery pipeline system with active flow turbulence function includes a mixing cylinder, a conical cylinder on the right side of the mixing cylinder, and a flow stabilizing cylinder on the right side of the conical cylinder. The mixing cylinder mixes the gas, and the flow stabilizing cylinder stabilizes the gas flow. Multiple inlet pipes (first and second) are evenly distributed at the left end of the mixing cylinder, spaced apart. A rotating rod is rotatably mounted inside the mixing cylinder, and a flow turbulence fan is mounted on the rotating rod. A transmission module is mounted inside the flow stabilizing cylinder, and a connecting rod is mounted on the transmission module. The airflow drives the transmission module to rotate, and the transmission module drives the rotating rod to rotate via the connecting rod. A flow stabilizing module is mounted inside the flow stabilizing cylinder, located to the right of the transmission module. A valve (first) is mounted on inlet pipe one, and a valve (second) is mounted on inlet pipe two.

[0008] The transmission module includes multiple evenly distributed transmission blades, which are connected to a connecting rod. The transmission module also includes a rotating drum, which is rotatably connected to the inside of a flow stabilizer. The transmission blades are connected to the inner side of the rotating drum. A rotating shaft is fixedly mounted inside the transmission blades and is rotatably connected to the connecting rod. A torsion spring is fitted onto the rotating shaft, with its two ends connected to the connecting rod and the transmission blades, respectively.

[0009] A locking pin is fixedly installed on the outer side of the rotating shaft, and a locking groove is opened inside the connecting rod, with the locking pin rotatably located within the locking groove. A movable groove is fixedly opened on the inner side of the rotating cylinder at the outer end of the drive fan blade, and a movable block is installed in the movable groove, which can move left and right. A limit rod is installed on the movable block. A strip-shaped groove is opened at the outer end of the drive fan blade, and the limit rod is movable within the strip-shaped groove. A spring is installed in the strip-shaped groove, with its two ends connected to the left end of the strip-shaped groove and the limit rod, respectively. Chamfers are opened on both the front and rear sides of the left side of the drive fan blade.

[0010] A transmission rod is rotatably mounted inside the rotating rod, allowing it to move left and right. A connecting rod, also rotatably mounted on its left end, is located inside the rotating rod. A slide rod is fixedly mounted on the right end of the transmission rod, and a connector is fixedly mounted on the right end of the slide rod. A connecting groove is formed on the left end of the connecting rod, and the slide rod and connector are rotatably mounted within this groove. Multiple fixing blocks (2) are evenly fixed to the inner side of the connecting groove, and multiple magnets (1) are evenly embedded therein, with the number of magnets equal to the number of fixing blocks (2). The outer side of the connector has the same number of magnets (2) as magnets (1), and the outer side of the connector has the same number of sliding grooves (3) as fixing blocks (2), allowing them to move left and right within these grooves. Multiple sliding grooves (1) are formed on the right side of the outer side of the transmission rod, and sliding grooves (2) are formed on the left side of the outer side of the connecting rod, corresponding to the number of sliding grooves (1). Multiple fixing blocks (1) are fixedly mounted on the inner side of the rotating rod, and these fixing blocks (1) are rotatably mounted within sliding grooves (1) and (2).

[0011] The left end of the transmission rod is movable left and right and rotatable, passing through the left end of the mixing cylinder. The transmission rod and the mixing cylinder are sealed together. A connecting block is fixedly installed at the left end of the mixing cylinder, through which the transmission rod passes. A lifting mechanism is installed on the side of the connecting block, and a connecting plate is installed at the output end of the lifting mechanism. The connecting plate is rotatably connected to the transmission rod, and the lifting mechanism drives the transmission rod to move up and down through the connecting plate. A limit groove is opened on the outer side of the transmission rod, and a driven gear is installed on the outer side of the transmission rod. A limit block is fixedly installed on the inner side of the driven gear. The limit block is movable and located in the limit groove, and the driven gear is rotatable and located at the upper end of the connecting block. A drive mechanism is installed on the connecting block, and a driving gear is fixedly installed at the upper end of the drive mechanism. The driving gear and the driven gear mesh with each other.

[0012] Beneficial effects: The present invention has the following technical effects when used:

[0013] 1. By setting up staggered air inlet pipes 1 and 2 at the left end of the mixing cylinder, different gases enter the mixing space in a spatially discrete and multi-channel coupling manner, breaking the single axial jet structure from the source, and promoting the formation of multi-scale convergence and mixing conditions of gases in the initial stage, thereby significantly reducing the subsequent mixing load and improving the overall mixing efficiency and uniformity.

[0014] 2. By setting a rotating rod and turbulence fan blades inside the mixing cylinder, and combining them with the transmission module inside the flow stabilizing cylinder to form a pneumatic energy recovery drive structure, the kinetic energy of the conveying airflow itself can be converted into turbulence power. This allows for continuous secondary disturbance compensation of the mixed gas without the need for additional energy input, thereby achieving a dynamic mixing mechanism of "flow disturbance - continuous homogenization".

[0015] 3. Through the staged flow channel structure design of conical cylinder and flow stabilizer, the gas undergoes diffusion mixing, contraction acceleration and flow shaping processes in sequence during the flow process. This achieves the step-by-step reconstruction of the flow field structure without increasing additional energy consumption, so that the outlet airflow has higher flow stability and directional consistency while maintaining the delivery efficiency.

[0016] 4. By introducing a dual-mode switching mechanism of active drive and passive pneumatic drive, and combining it with the coordinated control of lifting mechanism, gear transmission and magnetic positioning, the turbulence system can adaptively switch between "energy self-driven turbulence" and "externally enhanced turbulence" according to the working conditions. This breaks through the limitations of the traditional single drive mode on the adaptability of working conditions and improves the system's adaptability under different pressure, flow and ratio conditions.

[0017] 5. By setting a decoupled transmission structure, the transmission rod and connecting rod can switch between power transmission and functional isolation in different working modes, thereby avoiding mutual interference between different drive sources, ensuring the continuity and stability of the switching process between active and passive turbulence modes, and improving the reliability of system operation.

[0018] 6. Through the synergistic effect of the turbulent fan blade attitude adjustment structure and the elastic reset component, the fluid force can drive the fan blade to adaptively adjust within a preset angle range, thereby achieving dynamic optimization of the local flow field under different flow velocity conditions, taking into account the balance between mixing enhancement and steady flow output.

[0019] 7. By introducing a progressive flow field control path of "turbulence enhancement - energy utilization - flow shaping" into the overall structure, the hydrogen-rich gas mixture can simultaneously achieve improved mixing uniformity, optimized energy utilization efficiency, and stabilized output flow field during transportation, thereby improving transportation safety, process stability, and engineering applicability at the system level.

[0034] Example 1, such as Figure 1-12 As shown, the objective of this invention is achieved as follows: a hydrogen-rich mixed gas conveying pipeline system with active flow disturbance function, comprising a mixing cylinder 3, a conical cylinder 2 disposed on the right side of the mixing cylinder 3, and a flow stabilizing cylinder 1 disposed on the right side of the conical cylinder 2. The mixing cylinder 3 is used to mix multiple input gases, and the flow stabilizing cylinder 1 is used to perform flow shaping and conveying stabilization treatment on the mixed gas. Preferably, the mixing cylinder 3, the conical cylinder 2, and the flow stabilizing cylinder 1 are integrated or detachable sealed connection structures, and the connection method can be flange connection, welding connection, or other equivalent sealed flow guiding connection forms to ensure the continuity and sealing of gas conveying.

[0035] Multiple inlet pipes 4 and 5 are evenly distributed on the left end of the mixing cylinder 3, with the inlet pipes 4 and 5 spaced apart to create a multi-point dispersed input structure when different gases enter the mixing cylinder 3. A rotating rod 20 is rotatably mounted inside the mixing cylinder 3, and a turbulence-inducing fan blade 21 is mounted on the rotating rod 20. A transmission module is installed inside the flow stabilizing cylinder 1, and a connecting rod 19 is mounted on the transmission module. The airflow drives the transmission module to rotate, and the transmission module drives the rotating rod 20 to rotate via the connecting rod 19. A flow stabilizing module 17 is installed inside the flow stabilizing cylinder 1, located to the right of the transmission module. A valve 6 is mounted on the inlet pipe 4, and a valve 7 is mounted on the inlet pipe 5. The valves 6 and 7 are used to adjust the flow rate, velocity, and ratio of different gases to meet different hydrogen-rich mixing ratio requirements. Preferably, the structure of each pipeline component and the flow stabilizing module 17 can be adapted and adjusted according to the delivery pressure level.

[0036] By using a multi-channel staggered air intake and a segmented mixing and conveying structure, the gas is spatially dispersed and mixed in the initial stage. Combined with the subsequent flow stabilization structure, this achieves a synergistic improvement in mixing uniformity and conveying stability.

[0037] The transmission module includes multiple evenly distributed transmission blades 23, which are connected to the connecting rod 19. The transmission module also includes a rotating drum 18, which is rotatably connected to the inner side of the flow stabilizer 1. The transmission blades 23 are connected to the inner side of the rotating drum 18. Preferably, the rotating drum 18 is rotatably engaged with the inner wall of the flow stabilizer 1 via a bearing structure or a low-friction support structure to reduce rotational resistance and improve energy transfer efficiency.

[0038] By setting up a multi-bladed uniformly distributed transmission structure, the airflow can continuously act on multiple force points when flowing through the flow stabilizer 1, thereby improving the aerodynamic energy utilization rate and enhancing the driving stability of the rear-end turbulence mechanism.

[0039] A rotating shaft 25 is fixedly installed on the inner side of the transmission fan blade 23. The rotating shaft 25 is rotatably connected to the connecting rod 19. A torsion spring 27 is fitted on the rotating shaft 25, and both ends of the torsion spring 27 are connected to the connecting rod 19 and the transmission fan blade 23, respectively. Preferably, the torsion spring 27 is used to provide the restoring torque of the transmission fan blade 23, so that the transmission fan blade 23 can automatically return to a preset angle range when the airflow changes. The rotating shaft 25 and the connecting rod 19 are rotatably connected, and its specific form can be a bushing structure or a bearing structure.

[0040] Through the synergistic effect of the torsion spring 27 and the rotating shaft 25, the transmission fan blade 23 has the ability to adjust its angle adaptively, thereby maintaining a stable force posture under different airflow intensities and improving transmission continuity and anti-fluctuation ability.

[0041] A locking pin 24 is fixedly provided on the outer side of the rotating shaft 25, and a locking groove 26 is provided in the connecting rod 19. The locking pin 24 is rotatably located in the locking groove 26. Preferably, a limiting and guiding structure is formed between the locking pin 24 and the locking groove 26 to limit the displacement range of the rotating shaft 25 relative to the connecting rod 19, while allowing a certain angle of relative rotation to ensure transmission flexibility.

[0042] By using the limiting cooperation between the locking pin 24 and the locking slot 26, the transmission stability is ensured while avoiding excessive structural offset, thereby improving the overall transmission reliability and reducing the risk of structural mismatch.

[0043] A movable groove 22 is fixedly formed on the inner side of the rotating cylinder 18 at the outer end of the transmission fan blade 23. A movable block 38 is movably arranged in the movable groove 22, and a limit rod 37 is provided on the movable block 38. A strip-shaped groove is formed at the outer end of the transmission fan blade 23, and the limit rod 37 is movably located in the strip-shaped groove. A spring 39 is provided in the strip-shaped groove, and the two ends of the spring 39 are respectively connected to the left end of the strip-shaped groove and the limit rod 37. Chamfers are formed on the front and rear sides of the left side of the transmission fan blade 23. Preferably, the cooperation between the movable groove 22 and the strip-shaped groove is used to realize the attitude linkage adjustment of the transmission fan blade 23 during axial displacement.

[0044] The buffering effect of spring 39 and the guiding effect of limit rod 37 enable the transmission fan blade 23 to achieve a smooth angle transition during axial movement, thereby reducing airflow impact fluctuations and improving the flow stabilization effect. At the same time, the chamfered structure further reduces fluid separation and local resistance.

[0045] A transmission rod 9 is rotatably and can move left and right within the rotating rod 20. The left end of the connecting rod 19 is rotatably and can move left and right within the rotating rod 20. A slide rod 30 is fixedly installed at the right end of the transmission rod 9. A connector 34 is fixedly installed at the right end of the slide rod 30. A connecting groove is opened at the left end of the connecting rod 19. The slide rod 30 and the connector 34 are rotatably connected to the left end of the connecting rod 19. Multiple fixing blocks 32 are evenly fixedly installed on the inner side of the connecting groove. Multiple magnets 31 are evenly embedded on the inner side of the connecting groove. The number of magnets 31 is equal to the number of fixing blocks 32. The number of magnets 35 is evenly installed on the outer side of the connector 34. The number of sliding grooves 36 is equal to the number of fixing blocks 32. The fixing blocks 32 are rotatably and can move left and right within the sliding grooves 36. Preferably, the magnetic attraction structure is used to assist in alignment and switching positioning, so that the connector 34 and the connecting groove form an automatic guiding connection relationship.

[0046] By combining magnetic positioning with a sliding guide structure, the system can quickly switch between active and passive drive, and ensure stable connection of the transmission chain during the switching process, thereby improving system reliability and continuity of operation.

[0047] The transmission rod 9 has multiple sliding grooves 29 on its outer right side, and the connecting rod 19 has sliding grooves 33 on its outer left side, corresponding to the number of sliding grooves 29. Multiple fixing blocks 28 are fixedly installed on the inner side of the rotating rod 20, and these fixing blocks 28 are movable left and right within the sliding grooves 29 and 33. Preferably, the sliding grooves 29 and 33 are used to switch the transmission path under different working conditions.

[0048] By cooperating with the sliding groove assembly and the fixed block, the transmission rod 9 and the rotating rod 20 can achieve synchronous or decoupled transmission under different working conditions, thereby realizing multi-state switching of the turbulence mode and improving the system adaptability.

[0049] The left end of the transmission rod 9 is movable left and right and rotatable, passing through the left end of the mixing cylinder 3. The transmission rod 9 and the mixing cylinder 3 are sealed together. A connecting block 10 is fixedly installed at the left end of the mixing cylinder 3. The transmission rod 9 passes through the connecting block 10. A lifting mechanism 13 is provided on the side of the connecting block 10. A connecting plate 8 is provided at the output end of the lifting mechanism 13. The connecting plate 8 is rotatably connected to the transmission rod 9. The lifting mechanism 13 drives the transmission rod 9 to move up and down through the connecting plate 8. A limit groove 16 is opened on the outer side of the transmission rod 9. A driven gear 11 is provided on the outer side of the transmission rod 9. A limit block 15 is fixedly installed on the inner side of the driven gear 11. The limit block 15 is movable and located in the limit groove 16. The driven gear 11 is rotatably located at the upper end of the connecting block 10. A drive mechanism 14 is provided on the connecting block 10. A drive gear 12 is fixedly installed at the upper end of the drive mechanism 14. The drive gear 12 and the driven gear 11 mesh with each other. Preferably, the lifting mechanism 13 can be an electric push rod, a cylinder or other linear drive structure, and the drive mechanism 14 can be a motor drive structure. The specific form can be adjusted according to the application environment.

[0050] By combining lifting drive with gear transmission, the transmission rod 9 has both axial displacement and rotational drive capabilities, thereby achieving independent drive of active turbulence mode and enhancing overall power transmission efficiency and switching reliability.

[0051] In use, the raw gas is input through inlet pipe 2 5, and hydrogen is input through inlet pipe 1 4. Valves 1 6 and 2 7, respectively installed on inlet pipe 1 4 and inlet pipe 2 5, are used to regulate the flow rate and control the velocity of the different gases entering the mixing cylinder 3, so as to adjust the mixing ratio and conveying state according to actual usage requirements. Preferably, valves 1 6 and 2 7 can be electrically controlled valves, manual valves, or other valve body structures with the same regulating function, and their specific forms are not limited. Since inlet pipe 1 4 and inlet pipe 2 5 are evenly distributed circumferentially at the left end of the mixing cylinder 3, different gases can form a multi-point staggered input state when entering the mixing cylinder 3, so that the gas has a good mixing foundation in the initial stage. At the same time, the internal space of the mixing cylinder 3 is relatively large, and the flow velocity of the gas will decrease after entering, and a local turbulent flow field will be formed under the action of the turbulence fan blade 21, which is beneficial to improving the mixing uniformity. It should be noted that the "turbulent flow field" here is not limited to a completely turbulent flow in a strict sense, but refers to a local turbulent mixing state formed on the basis of overall axial conveying.

[0052] After being mixed, the gas enters the conical cylinder 2. Under the guiding transition of the conical cylinder 2, the gas flow cross-section gradually contracts, causing the airflow velocity to gradually increase and tend to concentrate, before entering the stabilizing cylinder 1. As the gas flows within the stabilizing cylinder 1, it drives the transmission module to rotate. The transmission module transmits rotational power to the rotating rod 20 via the connecting rod 19, thereby driving the turbulence-inducing fan blades 21 on the rotating rod 20 to rotate, achieving passive turbulent mixing of the gas within the mixing cylinder 3. It should be noted that the connection between the transmission module and the connecting rod 19, and between the connecting rod 19 and the rotating rod 20, are both power transmission connections. Specifically, the structure described in this application can be used, or an equivalent structure capable of achieving the same transmission function can be used to ensure the flexibility and replaceability of the structural implementation.

[0053] Specifically, the gas flow drives the transmission fan blade 23 to rotate, which in turn drives the connecting rod 19 to rotate. Through the transmission structure between the left side of the connecting rod 19 and the rotating rod 20, the rotating rod 20 rotates synchronously, thereby driving the turbulence fan blade 21 to rotate continuously within the mixing cylinder 3, thus enhancing the uniformity and dispersion of the mixed gas. During this transmission process, the transmission relationship between the transmission fan blade 23 and the connecting rod 19 can be switched according to the working state to meet different turbulence requirements.

[0054] When active turbulent mixing of the gas in the mixing cylinder 3 is required, the lifting mechanism 13 is activated by the controller. The lifting mechanism 13 drives the transmission rod 9 to move to the right via the connecting plate 8, and the transmission rod 9 then pushes the connecting rod 19 to move to the right in sync. During this process, as the connecting rod 19 moves to the right, the fixed block 28 gradually disengages from the slide groove 33 and enters the slide groove 29, thus achieving a smooth transition of the fixed block 28. At the same time, when the slide groove 36 on the connector 34 disengages from the fixed block 32, the left end of the fixed block 28 has usually entered the slide groove 29, thereby ensuring a smooth transition during the switching process. As the transmission rod 9 continues to move to the right, the fixed block 28 completely enters the slide groove 29 and disengages from the slide groove 33, and the connector 34 is located at the right end of the connecting groove. At this time, the transmission rod 9 and the connecting rod 19 are in a state where relative rotation is allowed. Subsequently, the controller controls the operation of the drive mechanism 14, which drives the drive gear 12 to rotate. After the drive gear 12 meshes with the driven gear 11, it drives the transmission rod 9 to rotate, thereby realizing the active rotation drive of the rotating rod 20, which in turn drives the turbulence fan blade 21 on the rotating rod 20 to actively rotate and turbulent the airflow. Since relative rotation is allowed between the transmission rod 9 and the connecting rod 19 at this time, the active rotation of the turbulence fan blade 21 is not limited by the state of the transmission fan blade 23, which is beneficial to improving the active turbulence effect and working stability.

[0055] As the transmission rod 9 moves to the right, it simultaneously drives the connecting rod 19 to move to the right, which in turn drives the transmission fan blade 23 to move to the right via the rotating shaft 25, causing the limiting rod 37 at the outer end of the transmission fan blade 23 to move along the direction of the moving groove 22. When the moving block 38 moves to the rightmost end of the moving groove 22, the connecting rod 19 continues to move to the right, causing the transmission fan blade 23 to continue to move and compressing the spring 39. The limiting rod 37 moves relative to the strip groove. Since the moving groove 22 is axially aligned with the connecting shaft, and with the rotation of the rotating shaft 25, the transmission fan blade 23 gradually adjusts its posture to be basically aligned with the axial direction of the flow stabilizer 1. At this time, the torsion spring 27 is in a tensioned or pre-tightened state. After the transmission fan blade 23 is aligned with the axial direction of the flow stabilizer 1, it can effectively reduce the obstruction to the gas flow and play a certain guiding and stabilizing role for the gas. It should be noted that the above-mentioned "flow stabilization" refers to making the overall gas flow direction more stable and the axial flow more concentrated, and does not require the gas to reach an absolutely ideal laminar flow state.

[0056] When passive turbulence needs to be restored, the controller controls the lifting mechanism 13 to reset and simultaneously controls the drive mechanism 14 to stop working. The lifting mechanism 13 drives the transmission rod 9 to move to the left, which in turn drives the connector 34 to move to the left. During the leftward movement of the connector 34, the magnet 35 and magnet 31 on the connector 34 attract each other under magnetic attraction, and under the attraction and guidance, drive the transmission rod 9 or the connecting rod 19 to rotate relative to each other, so that the slide groove 36 gradually aligns with the fixed block 32. After the two are attracted, the connector 34 continues to move to the left, so that the fixed block 32 is located in the slide groove 36. At this time, the slide groove 29 and the slide groove 33 are in the same straight line position and are connected to each other. Continuing to move to the left will allow the fixed block 28 to directly enter the slide groove 33, thereby re-establishing the transmission relationship between the connecting rod 19 and the rotating rod 20, and thus causing the transmission module to drive the turbulence fan blade 21 to rotate passively.

[0057] As the connecting rod 19 moves to the left, the transmission fan blade 23 moves synchronously to the left. The spring 39 gradually resets, and the transmission fan blade 23 rotates again under the reset force of the torsion spring 27, gradually returning to a state with a certain angle relative to the axial direction of the flow stabilizer 1. At this time, the airflow in the flow stabilizer 1 exerts a force on the transmission fan blade 23, pushing it to rotate further, which in turn drives the connecting rod 19 and the turbulence fan blade 21 to rotate, achieving passive turbulence. By setting the locking pin 24 and the locking groove 26, the maximum rotation angle of the transmission fan blade 23 can be limited under the action of the torsion spring 27, preventing it from excessively deflecting under the continuous action of the airflow, thereby improving structural stability and operational reliability. Preferably, the rotation direction of the transmission fan blade 23 is set to follow the direction of airflow propulsion to reduce flow resistance and ensure smooth transmission switching. It should be noted that the connection method, cooperation relationship and action sequence of the above-mentioned components can be equivalently replaced or partially adjusted without departing from the technical concept of this application. Any structural form that can achieve the same function or similar effect should be considered a reasonable modification of this application.

[0058] To further improve the structural adaptability and operational stability of this application during the switching process of different working modes, and to avoid unnecessary constraints, damping or reverse torque interference of the drive mechanism on the transmission rod in passive turbulence state or pneumatic drive state, this application preferably sets up a cooperative structural system with dynamic decoupling and non-rigid isolation characteristics between the drive mechanism 14 and the transmission rod 9.

[0059] Specifically, when the drive mechanism 14 is in the closed state or non-output state, the driving gear 12 no longer continuously applies driving torque to the driven gear 11. At this time, the driven gear 11 is in a "free state" in terms of structure. It only relies on the mechanical contact cooperation with the transmission rod 9 to achieve synchronous or semi-synchronous rotation, without forming a forced meshing drive relationship, thereby avoiding the drive mechanism 14 from forming a rigid lock or continuous load on the rotational freedom of the transmission rod 9.

[0060] Furthermore, an axial floating compensation structure or a micro-gap buffer structure is preferably provided between the driven gear 11 and the connecting block 10, so that the driven gear 11 can generate radial or axial compensation displacement within a preset small range when not driven, thereby absorbing the instantaneous impact force caused by airflow disturbance or inertial rotation, and avoiding jamming, jamming or reverse damping in the transmission chain.

[0061] Meanwhile, when the drive mechanism 14 is not activated, the driving gear 12 and the driven gear 11 are preferably kept in a weak meshing or clearance meshing state, that is, there is only a minimum meshing depth between them to maintain structural alignment, and no continuous torque transmission path is formed, so that the transmission rod 9 can still maintain a relatively independent rotational degree of freedom under the action of external airflow or the driving action of the transmission module.

[0062] In a preferred embodiment, a one-way buffer structure or friction release structure can be provided inside the driven gear 11 to significantly reduce the resistance generated by the drive mechanism 14 on the transmission rod 9 when it is not in operation, thereby achieving a "low-resistance follow-up and efficient decoupling" operating state.

[0063] It should be noted that the cooperation relationship between the drive mechanism 14 and the transmission rod 9 is not limited to gear meshing. In other equivalent embodiments, magnetic coupling transmission, clutch transmission, flexible coupling structure or intermittent meshing structure can also be used instead. As long as selective power transmission between active drive and passive follow-up can be achieved, they should be regarded as equivalent technical solutions of this application.

[0064] Through the above structural design, the drive mechanism 14 no longer forms a rigid constraint or continuous reverse torque input to the transmission rod 9 when it is not in operation. This achieves dynamic decoupling and functional isolation between the active drive system and the passive aerodynamic disturbance system from a structural perspective, thereby effectively avoiding mutual interference between different disturbance modes and improving the stability, reliability and response flexibility of the system under multiple operating conditions.

[0065] It should be noted that the specific structural forms, connection methods, and installation positions of the various components of the "hydrogen-rich mixed gas transportation pipeline system with active flow disturbance function" described in this application, such as the mixing cylinder, conical cylinder, flow stabilizing cylinder, transmission module, connecting rod, rotating rod, and flow stabilizing module, are not limited to the embodiments listed in the specification. The connection relationship between related components can also adopt welding, flange connection, threaded connection, snap-fit, or other equivalent connection methods that can achieve sealed transportation and stable transmission according to actual engineering needs.

[0066] Furthermore, the sliding fit, rotational fit, magnetic fit, and gear meshing structural relationships involved in this application are merely preferred implementations for switching between active and passive turbulence and for power transmission. Their specific structural parameters, fit clearances, and arrangement can all be equivalently replaced or partially adjusted without departing from the technical concept of this application. The component combination relationships between different implementation methods can also be adaptively configured according to gas flow rate, pressure level, and mixing ratio requirements.

[0067] Furthermore, the functional expressions such as "mixing," "turbulence," and "stabilization" mentioned in this application are all relative descriptions of the gas flow state. "Mixing" refers to the tendency of multiple gases to be evenly distributed in space, "turbulence" refers to the superposition of local disturbances on the basis of overall axial flow to enhance the mixing effect, and "stabilization" refers to reducing lateral disordered flow and making the overall airflow tend to be a stable transport state. They are not limited to an idealized physical state or an absolute flow state.

[0068] Meanwhile, the power transmission paths and switching mechanisms between the various structures in this application (including but not limited to pneumatic drive, mechanical transmission and magnetic assisted positioning) can be combined or replaced according to the actual application scenario. Under the premise that the same functional effect can be achieved, they should all be regarded as equivalent implementations within the scope of protection of this application.

[0069] As can be understood from the above description, the overall technical solution of this application belongs to a multi-structure collaborative gas delivery and turbulence control system. Its core lies in realizing switchable turbulence control between pneumatic drive and active drive, rather than being limited to a specific structural form, thereby improving structural adaptability and engineering application flexibility while ensuring functional realization.
