Description

Technical Field

[0001] This invention relates to the field of turbine technology, and in particular to a vibration-damping turbine based on an adjustable-angle blade assembly. Background Technology

[0002] As a core piece of equipment in the field of energy conversion, turbines are widely used in many critical scenarios such as power generation, aerospace, and industrial power transmission. Their operational stability and energy conversion efficiency directly affect the performance of the entire system. During the operation of a turbine, the flow state of the airflow after entering the equipment is crucial to the stress balance and energy absorption efficiency of the stator blades, and the precise adjustment of the stator blade angle is a key means to adapt to different airflow conditions and optimize the airflow trajectory.

[0003] In existing turbine stator blade angle adjustment technologies, there is a common problem of insufficient adaptability between the adjustment mechanism and the airflow conditions: some adjustment schemes rely on external drive components to achieve angle adjustment, which cannot adaptively respond according to the airflow magnitude, resulting in adjustment lag when the airflow fluctuates, affecting the real-time optimization of energy conversion; other adjustment structures use airflow-driven mechanisms, but lack effective angle limit and linkage disconnection mechanisms. When the airflow continues to increase, the stator blade angle may exceed the reasonable working range, which not only fails to further improve adaptability, but also causes equipment vibration due to the direct impact of the airflow on the adjustment components, aggravating component wear. Summary of the Invention

[0004] This invention provides a vibration-damping turbine based on an adjustable-angle blade assembly to address the problems mentioned in the background art, such as insufficient adaptability of the stator blade angle adjustment in existing turbines, lag in response of external drive schemes, lack of limit and linkage disconnection mechanisms in airflow drive schemes, and easy over-range operation leading to vibration and wear.

[0005] To solve the above-mentioned technical problems, the present invention provides a shock-absorbing turbine based on an adjustable angle blade assembly, comprising a main body, bearings disposed near both ends inside the main body, an inner shell disposed between the bearings inside the main body, a rotating shaft rotatably connected inside the bearings and passing through the inner shell, a stationary blade assembly disposed inside the inner shell, a moving blade rotatably connected to the inner shell near the stationary blade assembly outside the rotating shaft, the stationary blade assembly comprising a main body fixedly connected to the inner wall of the inner shell, blades disposed inside the main body, a movable cavity formed on the outer circumferential wall of the main body, a drive ring rotatably connected inside the movable cavity, and a docking bolt disposed near the top of one side of the drive ring; An outer tube is provided at the top of the main body near the stationary blade assembly. An inner tube assembly is provided inside the outer tube. The inner tube assembly includes a tube body fixedly installed inside the outer tube. A slide rod is provided inside the tube body. A baffle is hinged to the bottom end of the slide rod. A sliding plate is slidably connected to the outside of the tube body. A docking rod is provided at the bottom of the sliding plate near the docking bolt.

[0006] The present invention is further configured such that a first mating interface is provided on the outer wall of the main body at the position corresponding to the mating bolt, a pressure port is provided at the lower end of the mating rod near the mating bolt, and one end of the mating bolt extends through the first mating interface into the pressure port.

[0007] The present invention is further configured such that a docking plate is provided on one side of the drive ring near the docking bolt, one end of the docking plate extends through the docking interface to the outside of the movable cavity, and an elastic element is provided on the side of the docking plate located outside the movable cavity, one end of which is connected to the inner shell.

[0008] The invention is further configured such that the top and bottom of the blade are provided with docking shafts that are rotatably connected to the main body, one end of the docking shaft located at the top position extends into the interior of the movable cavity, and a driving block is fixedly connected to the top of the end of the docking shaft located inside the movable cavity. A driving groove is provided through the outer wall of the driving ring corresponding to the position of the driving block, and the top end of the driving block extends into the interior of the driving groove and is slidably connected.

[0009] The invention is further configured such that a sliding groove is provided inside the tube body, a limiting plate is provided inside the sliding groove near the middle position, the sliding rod is slidably connected to the inner wall of the sliding groove and the limiting plate, and a connecting plate is fixedly installed at the top of the sliding rod corresponding to the position of the limiting plate.

[0010] The invention is further configured such that a second interface is provided through the chute near the bottom, one side of the slide rod is fixedly connected to the slide plate through the second interface, and a top block is provided at the bottom of the baffle to be slidably connected to the inner wall of the chute.

[0011] The present invention is further configured such that an elastic element two is provided inside the slide rod above the baffle, one end of the elastic element two is connected to the baffle, and an elastic element three is provided at the top of the slide plate and the top end is connected to the outer tube.

[0012] The beneficial effects of this invention on a vibration-damping turbine based on an adjustable-angle blade assembly are as follows: 1. When high-pressure airflow enters through the pipe body, the airflow impacts the baffle, causing the sliding rod to fall along the sliding groove of the pipe body. The sliding rod, through the second interface, synchronously drives the sliding plate to move downwards. The sliding plate drives the docking rod to move downwards. The docking rod, through the pressure port, squeezes the docking bolt of the drive ring, causing the drive ring to rotate within the movable cavity of the stator blade assembly body. When the drive ring rotates, the drive groove on its outer wall pulls the drive block on the blade docking shaft, causing the blade to rotate around the docking shaft. The rotation angle of the blade can be precisely controlled by the degree of descent of the airflow impacting the baffle, achieving real-time adaptation to the airflow conditions and ensuring real-time optimization of energy conversion. 2. When the airflow is too strong, the connecting plate at the top of the slide rod aligns with the limiting plate inside the tube, restricting the slide rod from moving further downward and thus limiting the blade flip angle to the maximum reasonable range. Simultaneously, the top block at the bottom of the baffle disengages from the slide groove. Freed from the slide groove's constraint, the baffle flips downward with the impact of the airflow, and the top block simultaneously locks onto the bottom of the tube. This forcibly fixes the baffle's position, preventing it from swaying or shifting downward under strong airflow, and also disconnects the linkage between the baffle and the slide rod, preventing the slide plate and connecting rod from moving with the airflow fluctuations and causing the drive ring to move. This ensures the maximum blade angle remains stable and prevents abnormal angle changes from affecting equipment operation. Attached Figure Description

[0019] Please see Figure 1 - Figure 8 A shock-absorbing turbine based on an adjustable angle blade assembly includes a body 1. Bearings 11 are arranged near both ends inside the body 1. An inner shell 13 is arranged between the bearings 11 inside the body 1. A rotating shaft 12 is rotatably connected inside the bearings 11 and passes through the inner shell 13. A stationary blade assembly 14 is arranged inside the inner shell 13. A moving blade 15 is arranged near the stationary blade assembly 14 outside the rotating shaft 12 and rotatably connected to the inner shell 13. The stationary blade assembly 14 includes a main body 141 fixedly connected to the inner wall of the inner shell 13. Blades 142 are arranged inside the main body 141. A movable cavity 1411 is opened on the outer circumference of the main body 141. A drive ring 143 is rotatably connected inside the movable cavity 1411. A docking bolt 1432 is arranged on one side of the drive ring 143 near the top. An outer tube 16 is provided at the top of the main body 1 near the stationary blade assembly 14. An inner tube assembly 17 is provided inside the outer tube 16. The inner tube assembly 17 includes a tube body 171 fixedly installed inside the outer tube 16. A slide rod 172 is provided inside the tube body 171. A baffle 173 is hinged to the bottom end of the slide rod 172. A sliding plate 176 is slidably connected to the outside of the tube body 171. A docking rod 178 is provided at the bottom of the sliding plate 176 near the docking bolt 1432.

[0020] By adopting the above technical solution, the rotating shaft 12 rotates stably through the inner shell 13 via the bearings 11 at both ends. The bearings 11 bear the radial load and allow free rotation. The main body 141 is fixed to the inner wall of the inner shell 13, and the movable cavity 1411 accommodates the drive ring 143. The drive ring 143 is linked to the docking rod 178 via the docking bolt 1432, which converts the displacement of the baffle 173 into the angle adjustment of the blade 142. The slide rod 172 inside the tube 171 is hinged to the baffle 173. The baffle 173 moves downward under the impact of airflow, and the slide rod 172 drives the slide plate 176 to slide along the outer wall of the tube 171. The docking rod 178 at the bottom of the slide plate 176 engages with the docking bolt 1432, converting its displacement into the rotation of the drive ring 143. The moving blade 15 is mounted on the rotating shaft 12 and rotatably connected to the inner shell 13, forming a complete energy conversion channel near the stationary blade assembly 14.

[0021] A mating interface 1412 is provided on the outer wall of the main body 141 at the position corresponding to the mating bolt 1432. A pressure port 1781 is provided at the lower end of the mating rod 178 near the mating bolt 1432. One end of the mating bolt 1432 extends through the mating interface 1412 into the pressure port 1781. A mating plate 1433 is provided on one side of the drive ring 143 near the mating bolt 1432. One end of the mating plate 1433 extends through the mating interface 1412 into the outside of the movable cavity 1411. An elastic element 1434 is provided on the side of the mating plate 1433 located outside the movable cavity 1411, with one end connected to the inner shell 13.

[0022] By adopting the above technical solution, the docking bolt 1432 passes through the docking interface 1412 of the main body 141 and extends into the pressure port 1781, thereby connecting the drive ring 143 with the docking rod 178. When the docking rod 178 moves downward, the pressure port 1781 squeezes the docking bolt 1432, converting the linear motion into rotation of the drive ring 143. The docking plate 1433 is connected to the elastic element 1434, which drives the drive ring 143 to rotate in the opposite direction when the airflow decreases, causing the blade 142 to return to its original position. The docking interface 1412 limits the docking bolt 1432 to prevent the blade 142 from exceeding its angle limit, and the inclined surface of the pressure port 1781 optimizes the force transmission efficiency.

[0023] The blade 142 is provided with docking shafts 1421 at the top and bottom, which are rotatably connected to the main body 141. One end of the docking shaft 1421 located at the top extends into the interior of the movable cavity 1411. A drive block 1422 is fixedly connected to the top of the end of the docking shaft 1421 located inside the movable cavity 1411. A drive groove 1431 is provided on the outer wall of the drive ring 143 corresponding to the position of the drive block 1422. The top end of the drive block 1422 extends into the interior of the drive groove 1431 and is slidably connected.

[0024] By adopting the above technical solution, the blade 142 is rotatably connected to the main body 141 via the top and bottom docking shafts 1421, forming a rotation fulcrum. The top docking shaft 1421 extends into the movable cavity 1411, and the top drive block 1422 extends into the drive groove 1431 of the drive ring 143. When the drive ring 143 rotates, the arc-shaped trajectory of the drive groove 1431 converts the rotational motion into the linear displacement of the drive block 1422, which adjusts the angle of the blade 142 via the docking shaft 1421. The movable cavity 1411 provides and limits the movement of the drive ring 143 and the drive block 1422, preventing interference and detachment of the components.

[0025] The tube body 171 has a sliding groove 1711 inside, and a limiting plate 1713 is set near the middle position inside the sliding groove 1711. The sliding rod 172 is slidably connected to the inner wall of the sliding groove 1711 and the limiting plate 1713. A connecting plate 175 is fixedly installed at the top of the sliding rod 172 corresponding to the position of the limiting plate 1713. A connecting interface 1712 is opened through the sliding groove 1711 near the bottom. One side of the sliding rod 172 is fixedly connected to the slide plate 176 through the connecting interface 1712. A top block 1731 is set at the bottom of the baffle 173, which is slidably connected to the inner wall of the sliding groove 1711. An elastic element 174 is set inside the sliding rod 172 above the baffle 173. One end of the elastic element 174 is connected to the baffle 173. An elastic element 177 is set at the top of the slide plate 176, which is connected to the outer tube 16.

[0026] By adopting the above technical solution, the slide groove 1711 provides vertical guidance for the slide rod 172, and the middle limiting plate 1713 contacts the connecting plate 175 to limit the maximum stroke of the slide rod 172 and prevent excessive downward movement. The slide rod 172 is rigidly connected to the slide plate 176 via the second interface 1712 to ensure accurate transmission of the baffle 173 displacement. The bottom top block 1731 of the baffle 173 slides within the slide groove 1711, supporting and limiting the initial position. When it moves to the limit, it disengages from the slide groove 1711 to achieve flipping and unlocking. The second elastic element 174 connects the slide rod 172 and the baffle 173, absorbing vibration and preventing rigid damage; the third elastic element 177 connects the slide plate 176 and the outer tube 16, and when the airflow decreases, it drives the slide plate 176, slide rod 172, and baffle 173 to reset. The second interface 1712 keeps the movement of the two synchronized and maintains the structural integrity of the tube body 171.

[0027] Working principle and usage process of this invention: The bottom of the baffle 173 is provided with a top block 1731 for support, so the baffle 173 will not flip when it does not exceed a certain limit. The connecting plate 175 on the top of the slide rod 172 cooperates with the limiting plate 1713 for limiting. When the slide plate 176 is pressed down by the airflow impact, the elastic element 177 on the top of the slide plate 176 absorbs the impact force through its own extension and contraction, avoiding rigid collision between the slide plate 176 and other components such as the docking rod 178 and the docking bolt 1432, thus reducing equipment vibration. When the airflow decreases or disappears, the elastic rebound force of the elastic element 177 can pull the slide plate 176 upward to reset, thereby driving the slide rod 172 and the baffle 173 to return to their initial positions. At the same time, the drive ring 143 is linked through the docking rod 178 to restore the angle of the blade 142 to a state that is adapted to the small airflow conditions.

[0028] During use, high-pressure airflow enters the body 1 through pipe 171. As the airflow passes through the inside of pipe 171, it impacts the internal baffle 173. When impacted by the airflow, the baffle 173 falls along pipe 171. Simultaneously, the falling baffle 173 drives the sliding rod 172 down along the slide groove 1711. As the sliding rod 172 falls, it also drives the sliding plate 176 down through the second docking port 1712. As the sliding plate 176 falls, it drives the docking rod 178 down. The downward movement of the docking rod 178 compresses the docking bolt 1432 through the pressure port 1781. By squeezing, the docking bolt 1432 drives the drive ring 143 to rotate. The rotation of the drive ring 143 pulls the drive block 1422 through the drive groove 1431. By pulling the drive block 1422, the blade 142 flips around the docking shaft 1421. The flipping angle of the blade 142 is controlled by the degree of fall of the airflow impact baffle 173. When the airflow decreases, the elastic element 3 177 drives the docking rod 178 to move upward. Simultaneously, the elastic element 1 1434 also drives the drive ring 143 to reset by pulling the docking plate 1433.

[0029] When the high-pressure airflow entering through the pipe 171 is too strong, the impact baffle 173 will continue to fall until it reaches the connection plate 175 and the limiting plate 1713. At this time, the blade 142 will flip to its maximum angle, and the top block 1731 at the bottom of the baffle 173 will disengage from the slide groove 1711. With the baffle 173 no longer restricted by the slide groove 1711, it will flip downwards as the airflow impacts it. After flipping, the baffle 173 will not protrude inside the pipe 171, reducing obstruction of the high-pressure airflow, lowering flow resistance, and ensuring that the airflow enters the turbine in a more stable state, avoiding airflow turbulence and equipment vibration caused by the wobbling of the baffle 173. Simultaneously, the flipping of the baffle 173 will cause the top block 1731 to engage with the bottom of the pipe 171. This engagement of the top block 1731 with the bottom of the pipe 171 forcibly fixes the position of the baffle 173, preventing it from further shifting or wobbling under continuous strong airflow impact. After the baffle 173 is locked, its linkage with the slide bar 172 is mechanically locked, and it no longer drives the slide plate 176 and the docking rod 178 to move with the airflow fluctuations, thereby completely disconnecting the transmission connection with the drive ring 143, ensuring that the maximum angle state of the blade 142 is stable, and avoiding abnormal angle changes caused by continuous airflow impact.

[0030] In summary, compared with the prior art, the embodiments of the present invention have the following advantages: Advantage 1: Achieves adaptive airflow adjustment of the stationary blade angle without the need for external drive components, solving the problem of lag in response of existing external drive solutions. High-pressure airflow impacts the baffle 173 and falls along the pipe body 171, causing the slide rod 172 to move down along the slide groove 1711. The slide rod 172 drives the slide plate 176 to move down through the second interface 1712. The slide plate 176 drives the docking rod 178 to move down. The docking rod 178 squeezes the docking bolt 1432 through the pressure port 1781, causing the drive ring 143 to rotate in the movable cavity 1411. The drive ring 143 pulls the drive block 1422 through the drive groove 1431, causing the blade 142 to rotate around the docking shaft 1421. The adjustment angle of the blade 142 is precisely controlled by the degree of descent of the airflow impacting the baffle 173, achieving real-time adaptation to the airflow conditions.

[0031] Advantage 2: It has a reliable angle limiting and linkage disconnection mechanism, which solves the problems of lack of limiting and easy over-range in the existing airflow drive scheme. When the airflow is too large, the connecting plate 175 at the top of the slide rod 172 docks with the limiting plate 1713 in the tube body 171, which limits the slide rod 172 from moving further down, thereby limiting the blade 142 to flip to the maximum angle. At the same time, the top block 1731 at the bottom of the baffle 173 disengages from the slide groove 1711. After the baffle 173 flips, the top block 1731 is stuck at the bottom of the tube body 171, fixing the position of the baffle 173 and disconnecting its linkage with the slide rod 172. This prevents the slide rod 172, slide plate 176, and docking rod 178 from driving the drive ring 143 to continue moving, ensuring the stability of the maximum angle of the blade 142.

[0032] Thirdly, it effectively reduces vibration and optimizes airflow, solving the problem of vibration caused by airflow impact in existing solutions. The elastic element 177 at the top of the slide plate 176 absorbs the impact force when the slide plate 176 moves downward, avoiding rigid collisions between the slide plate 176 and the connecting rod 178, and between the connecting rod 178 and the connecting bolt 1432. The elastic element 1434 connected to the connecting plate 1433 on one side of the drive ring 143 assists the drive ring 143 in resetting, reducing vibration. Furthermore, the baffle 173 does not protrude from the pipe body 171 after flipping, reducing flow resistance, avoiding airflow turbulence, and further reducing equipment vibration and component wear.

[0033] Fourthly, the reset is stable and reliable, ensuring that the blade 142 accurately returns to the angle suitable for the small airflow. When the airflow decreases, the elastic element 177 pulls the slide plate 176 upward, causing the slide rod 172 and the baffle 173 to reset. The elastic element 1434 pulls the docking plate 1433, causing the drive ring 143 to rotate in the opposite direction. Through the drive groove 1431, it pushes the drive block 1422 to reset the blade 142, ensuring that the blade 142 returns to the angle suitable for the small airflow and avoiding reset deviation from affecting efficiency.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
