Description

Technical Field

[0001] This invention belongs to the field of guide wheel blade technology, specifically an adaptive angle adjustment mechanism for guide wheel blades. Background Technology

[0002] Guide vane blades are key components in fluid machinery used to guide and regulate fluid flow. They typically employ a streamlined airfoil design and can be fixedly installed or dynamically adjusted in angle via mechanical, hydraulic, or electric devices. Their core function is to optimize fluid direction, velocity, and pressure distribution, reduce energy loss and eddy current generation, and adapt to different operating conditions. Applications are wide-ranging, covering hydropower (turbine guide vanes control water flow energy conversion), aerospace (turbocharger guide vanes recover exhaust energy, aero-engine compressors compress gas in stages), marine engineering (adjustable propeller guide vanes match speed and load), industrial equipment (centrifugal compressor guide vanes increase gas pressure), and new energy (wind turbine pitch guide vanes adjust wind energy capture efficiency). They are core components for improving equipment efficiency, stability, and adaptability.

[0003] Existing guide vane blades cannot adaptively adjust their angle in real time. When faced with changes in operating conditions such as flow rate and pressure, they cannot dynamically adjust their angle, which can easily lead to fluid mismatch, resulting in decreased efficiency and energy waste. Furthermore, overload or cavitation may exacerbate wear, shorten equipment life, and increase maintenance costs. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an adaptive angle adjustment mechanism for guide vanes, which effectively solves the problem that the existing guide vanes cannot perform real-time adaptive angle adjustment and cannot dynamically adjust the angle when facing changes in operating conditions such as flow rate and pressure, which easily leads to fluid matching imbalance, resulting in decreased efficiency and energy waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive angle adjustment mechanism for guide wheel blades, comprising a device housing, an inlet fixedly installed on one side of the circumferential surface of the device housing, an outlet fixedly installed on the top of the circumferential surface of the device housing, a protective cover fixedly installed on one side of the device housing, a first sealed bearing fixedly installed on the other side of the device housing, a drive shaft rotatably installed in the middle of the first sealed bearing, one end of the drive shaft extending into the interior of the device housing and a second sealed bearing rotatably installed on its end surface, a baffle fixedly installed between the surface of the second sealed bearing and the inner wall of the device housing, a transmission gear fixedly installed on one side of the baffle and on the surface of the drive shaft, an electronic power take-off fixedly installed on the upper part of one side of the baffle, the input end of the electronic power take-off meshing with the transmission gear, and a plurality of blade bodies arranged circumferentially at equal intervals on the surface of the device housing, the ends of the plurality of blade bodies near the drive shaft being rotatably connected to the drive shaft through a bearing seat;

[0006] A movable ring is fitted in the middle of the drive shaft surface. Several mounting blocks are fixedly installed at equal intervals around the surface of the movable ring. A strip groove is opened on one side of the mounting block, and a pin is inserted into the inside of each strip groove. One end of each pin is fixedly installed at the end of the corresponding blade body. A transmission component is provided at the output end of the electronic power take-off. The transmission component is connected to the movable ring. The electronic power take-off outputs the power of the output shaft to the movable ring through the transmission component, so that the movable ring moves.

[0007] Preferably, one end of the drive shaft is fixedly connected to the output end of an external servo motor, and a pressure sensor and a flow sensor are fixedly installed inside the housing of the device. The external servo motor, pressure sensor, flow sensor, and electronic power take-off are all connected to an external PLC logic controller via a wireless transmission module.

[0008] Preferably, the transmission assembly includes a shaft, which is fixedly installed at the output end of the electronic power take-off. One end of the shaft extends into the interior of the protective cover and is fixedly installed with an upper sprocket. The surface of the shaft is rotatably connected to the device housing through a first bushing. A lower sprocket is provided below the upper sprocket, and a chain is meshed between the lower sprocket and the upper sprocket.

[0009] Preferably, a positioning frame is rotatably mounted between one side of the lower sprocket and the upper sprocket, and the lower end of the positioning frame is fixedly connected to the outer casing of the device.

[0010] Preferably, a rotating shaft is fixedly installed on the side of the lower sprocket away from the positioning frame, and a sleeve is fixedly installed inside the protective cover and in the middle of the device housing via a fixing sleeve. One end of the rotating shaft extends into the inside of the sleeve and is fixedly installed with a threaded rod, and the surface of the rotating shaft is rotatably connected to one end of the sleeve via a second bushing.

[0011] Preferably, the threaded rod extends into the interior of the drive shaft and is threadedly connected to a threaded sleeve on its surface. A fixing ring is fixedly installed on the surface of the threaded sleeve. Support arms are fixedly installed on the upper and lower parts of one side of the fixing ring. A slider is fixedly installed at one end of each support arm. Two sliding grooves are symmetrically opened on the inner wall of the sleeve, and two sliders are slidably installed inside the two sliding grooves.

[0012] Preferably, a fixing rod is rotatably mounted on one end of the threaded sleeve, and both ends of the fixing rod are fixedly connected to the inner wall of the movable sleeve.

[0013] Preferably, one end of the threaded sleeve is rotatably connected to the middle of one side of the fixed rod via a rotating seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) When in use, the operator starts the external servo motor through the external PLC logic controller to drive the drive shaft to rotate inside the first and second sealed bearings. When the drive shaft rotates, it will drive the transmission gear to rotate. At the same time, the drive shaft will also drive several blade bodies to rotate, so that the water inlet will suck in the water and the water outlet will discharge the water, thereby realizing the water pumping function. During the water pumping process, the pressure sensor and flow sensor will monitor the pressure and flow data inside the device housing in real time, and transmit the data to the external PLC logic controller in real time through the wireless transmission module. The PLC logic controller will automatically control the operation of the electronic power take-off. The electronic power take-off will output the power of the transmission gear to the shaft, so that the shaft rotates inside the first bushing and drives the upper sprocket to rotate.

[0016] (2) When the upper sprocket rotates, it drives the lower sprocket to rotate via the chain. When the lower sprocket rotates, it drives the rotating shaft to rotate inside the second bushing. When the rotating shaft rotates, it drives the threaded sleeve to move via the threaded rod. When the threaded sleeve moves, it drives the slider to slide inside the groove via the fixed ring and two support arms, which increases the stability of the threaded sleeve when it moves. When the threaded sleeve moves, it drives the moving ring to move via the rotating seat and the fixed rod. When the moving ring moves, it drives several mounting blocks to move. When several mounting blocks move, they push several pins through the cooperation of several slots, so that several pins drive several blade bodies to rotate along the shaft seat to adjust the angle, so that several blade bodies can maintain the best performance according to the changes in flow and pressure. Since the threaded sleeve is rotatably connected to the fixed rod via the rotating seat, the normal movement of the threaded sleeve will not be affected when the drive shaft rotates, so that the power of the electronic power take-off can be effectively transmitted to the moving ring.

[0017] (3) This allows the guide vane blades to adaptively adjust the angle according to changes in flow rate and pressure, avoiding problems such as decreased efficiency and energy waste caused by fluid mismatch. It can also avoid increased wear caused by overload or cavitation, improve equipment life and reduce maintenance costs. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1 to 7The present invention includes a device housing 1, an inlet 2 fixedly installed on one side of the circumferential surface of the device housing 1, an outlet 3 fixedly installed on the top of the circumferential surface of the device housing 1, a protective cover 4 fixedly installed on one side of the device housing 1, a first sealed bearing 6 fixedly installed on the other side of the device housing 1, a drive shaft 5 rotatably installed in the middle of the first sealed bearing 6, one end of the drive shaft 5 extending into the interior of the device housing 1 and a second sealed bearing 10 rotatably installed on its end surface, a baffle 8 fixedly installed between the surface of the second sealed bearing 10 and the inner wall of the device housing 1, a transmission gear 34 fixedly installed on one side of the baffle 8 and on the surface of the drive shaft 5, an electronic power take-off 9 fixedly installed on the upper part of one side of the baffle 8, the input end of the electronic power take-off 9 meshing with the transmission gear 34, and a plurality of blade bodies 7 are arranged circumferentially at equal intervals on the surface of the device housing 1, and the ends of the plurality of blade bodies 7 near the drive shaft 5 are rotatably connected to the drive shaft 5 through a bearing seat 15.

[0030] A movable ring 11 is fitted in the middle of the surface of the drive shaft 5. Several mounting blocks 12 are fixedly installed in a ring at equal intervals on the surface of the movable ring 11. A strip groove 13 is opened on one side of the mounting block 12. Pins 14 are inserted into the inside of each strip groove 13. One end of each pin 14 is fixedly installed at the end of the corresponding blade body 7. A transmission assembly is provided at the output end of the electronic power take-off 9. The transmission assembly is connected to the movable ring 11. The electronic power take-off 9 outputs the power of the output shaft 5 to the movable ring 11 through the transmission assembly, so that the movable ring 11 moves.

[0031] One end of the drive shaft 5 is fixedly connected to the output end of the external servo motor. A pressure sensor and a flow sensor are fixedly installed inside the housing 1 of the device. The external servo motor, pressure sensor, flow sensor and electronic power take-off 9 are all connected to the external PLC logic controller through a wireless transmission module.

[0032] In use, the operator starts the external servo motor through the external PLC logic controller to drive the drive shaft 5 to rotate inside the first sealed bearing 6 and the second sealed bearing 10. When the drive shaft 5 rotates, it will drive the transmission gear 34 to rotate. At the same time, the drive shaft 5 will also drive several blade bodies 7 to rotate, so that the inlet 2 draws in water and the outlet 3 discharges water, thereby realizing the water pumping function. During the water pumping process, the pressure sensor and the flow sensor will monitor the pressure and flow data inside the device housing 1 in real time, and transmit the data to the external PLC logic controller in real time through the wireless transmission module. The PLC logic controller automatically controls the operation of the electronic power take-off 9, and the electronic power take-off 9 will output the power of the transmission gear 34 to the transmission components.

[0033] When the transmission component is running, it will drive the moving ring 11 to move. When the moving ring 11 moves, it will drive several mounting blocks 12 to move. When the mounting blocks 12 move, they will push several pins 14 through the cooperation of several strip grooves 13. This will cause several pins 14 to drive several blade bodies 7 to rotate along the shaft seat 15 to adjust the angle, so that several blade bodies 7 can maintain optimal performance according to changes in flow rate and pressure.

[0034] In Embodiment 2, based on Embodiment 1, the transmission assembly includes a shaft 16, which is fixedly installed at the output end of the electronic power take-off 9. One end of the shaft 16 extends into the interior of the protective cover 4 and is fixedly mounted with an upper sprocket 20. The surface of the shaft 16 is rotatably connected to the device housing 1 through a first bushing 17. A lower sprocket 21 is provided below the upper sprocket 20, and a chain 23 is meshed between the lower sprocket 21 and the upper sprocket 20. A positioning frame 22 is rotatably mounted between one side of the lower sprocket 21 and the upper sprocket 20, and the lower end of the positioning frame 22 is fixedly connected to the device housing 1.

[0035] The electronic power take-off 9 outputs power from the transmission gear 34 to the shaft 16, causing the shaft 16 to rotate inside the first bushing 17 and drive the upper sprocket 20 to rotate. When the upper sprocket 20 rotates, it drives the lower sprocket 21 to rotate through the chain 23.

[0036] A rotating shaft 24 is fixedly installed on the side of the lower sprocket 21 away from the positioning frame 22. A sleeve 19 is fixedly installed inside the protective cover 4 and in the middle of one side of the device housing 1 through a fixing sleeve 18. One end of the rotating shaft 24 extends into the inside of the sleeve 19 and is fixedly installed with a threaded rod 26. The surface of the rotating shaft 24 is rotatably connected to one end of the sleeve 19 through a second bushing 25.

[0037] The threaded rod 26 extends into the interior of the drive shaft 5 and is threadedly connected to the surface of the threaded sleeve 27. A fixing ring 31 is fixedly installed on the surface of the threaded sleeve 27. A support arm 28 is fixedly installed on the upper and lower parts of one side of the fixing ring 31. A slider 29 is fixedly installed on one end of each support arm 28. Two sliding grooves 30 are symmetrically opened on the inner wall of the sleeve 19. The two sliders 29 are slidably installed inside the two sliding grooves 30.

[0038] When the lower sprocket 21 rotates, it drives the shaft 24 to rotate inside the second bushing 25. When the shaft 24 rotates, it drives the threaded sleeve 27 to move through the threaded rod 26. When the threaded sleeve 27 moves, it drives the slider 29 to slide inside the groove 30 through the fixed ring 31 and the two support arms 28, which increases the stability of the threaded sleeve 27 when it moves.

[0039] A fixed rod 33 is rotatably mounted on one end of the threaded sleeve 27, and both ends of the fixed rod 33 are fixedly connected to the inner wall of the movable sleeve 11; one end of the threaded sleeve 27 is rotatably connected to the middle part of one side of the fixed rod 33 through the rotating seat 32.

[0040] When the threaded sleeve 27 moves, it drives the moving ring 11 to move through the rotating seat 32 and the fixed rod 33.

[0041] Since the threaded sleeve 27 is rotatably connected to the fixed rod 33 via the rotating seat 32, the normal movement of the threaded sleeve 27 will not be affected when the drive shaft 5 rotates, so that the power of the electronic power take-off 9 can be effectively transmitted to the moving ring 11.
