Description

Technical Field

[0001] The present invention belongs to the technical field of water turbines, and more specifically, particularly relates to an adjustable vane water turbine. Background Art

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbomachinery in fluid machinery. In a hydropower station, the water in the upstream reservoir is led to the water turbine through a water inlet pipe, which drives the rotation of the water turbine runner and drives the generator to generate electricity. The water that has done work is then discharged downstream through the tail water pipe. The higher the water head and the larger the water flow, the greater the output power of the water turbine. In use, it has the following deficiencies.

[0003] 1. One end of the water turbine guides the water flow into the interior of the water turbine through a pipeline. The water flow introduced into the interior of the water turbine in each time period is not uniform. In addition, the internal blades of the water turbine mainly rely on the flow of the water source to drive rotation. If the change in water volume is large in a short period of time, it is easy to cause large fluctuations in the rotation speed of the blades, which is not convenient for driving the rotating shaft to generate electricity.

[0004] 2. Especially in the time period with a small water flow, when the water flow is guided into the interior of the water turbine, the impact force of the water flow on the blades is greatly reduced. The number of internal blades of the water turbine is fixed and the spacing is large, and the water flow will directly flow through between the blades and cannot impact the blades to drive the rotating shaft.

[0005] 3. Most of the internal blades of the water turbine are of a single-layer design. The water flow impacts the blades to drive the rotation of the rotating shaft to generate electricity. However, after the water flow impacts the blades and flows downward, part of the water flow directly flows downward through the spacing between the blades and still has a certain amount of kinetic energy. The single-layer blades cannot make full use of the kinetic energy of the water flow. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides an adjustable vane water turbine to solve the above problems.

[0007] The adjustable vane water turbine includes a runner chamber. A sealing seat ring is fixedly installed at the top end of the runner chamber. A fixing frame is fixedly installed inside the sealing seat ring. At least two support plates are fixedly installed on the outer side of the fixing frame. A top plate is fixedly installed at the top end of the sealing seat ring. A main shaft is rotatably installed inside the top plate. A first runner body is fixedly installed at the bottom end of the main shaft. At least two blade bodies are fixedly installed on the surface of the first runner body. A second runner body is movably installed at the bottom end of the first runner body. At least two guide vanes are rotatably installed inside the sealing seat ring. A fixing shaft is fixedly installed at the bottom end of each guide vane;

[0008] Among them, each of the flow guiding plates is inclinedly installed inside the sealing seat ring, and the spacing between each flow guiding plate is the same. At the same time, the surface of the second runner body is also provided with blade bodies, and the top end of the second runner body fits with the bottom end of the first runner body.

[0009] Preferably, a docking cylinder is rotatably installed at the top end of the second runner body, two limiting blocks are slidably installed at the top end of the docking cylinder, and a reset rod is fixedly installed at the bottom end of each limiting block;

[0010] Among them, the top end of the limiting block is fixedly connected to the bottom end of the first runner body. The first runner body itself is trapezoidally designed. At least two transmission rods are rotatably installed on the outside of the fixing frame, at least two driving boxes are fixedly installed on the inside of each fixing frame, and a gear set is installed at the side end of each driving box;

[0011] Among them, a driving motor is installed inside the driving box and is connected to one side of the gear set through a rotating shaft. A connecting sleeve is arranged on the outside of the main shaft, and a second fixing ring is rotatably installed at the bottom end of the connecting sleeve.

[0012] Preferably, at least two telescopic rods are fixedly installed at the bottom end of the second fixing ring;

[0013] A gear ring is fixedly installed at the top end of the connecting sleeve;

[0014] Among them, the surface of the gear ring is aligned with a plurality of driving boxes, and at the same time, the top end of the gear ring is snap-fitted with the gear set. A first fixing ring is fixedly installed at the bottom end of the connecting sleeve, and at least two fixing legs are fixedly installed at the bottom end of the first fixing ring.

[0015] Preferably, a groove is formed on the inner side wall of the sealing seat ring;

[0016] A first fixing sleeve is fixedly installed at the top end of each flow guiding plate, a driving rod is rotatably installed at the side end of each first fixing sleeve, and a second fixing sleeve is arranged at the end of each driving rod;

[0017] Among them, the end of the second fixing sleeve is fixedly connected to the inner side wall of the groove, and the end of the second fixing sleeve is simultaneously rotatably connected to the corresponding transmission rod. A water inlet pipe is fixedly installed on the outside of the sealing seat ring, and a chamber is formed at the side end of the water inlet pipe;

[0018] Among them, the chamber extends to one side and is connected to the inside of the sealing seat ring in a penetrating manner.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, by driving the connecting sleeve to rotate, the connecting sleeve drives the first fixed ring at the end to rotate, so that the first fixed ring drives the fixed support leg to deflect slightly. Since the end of the fixed support leg is fixedly connected to the second rotor body, the second rotor body is allowed to move and deflect at the bottom end of the first rotor body. The second rotor body and the docking tube rotate relative to each other, and the position of the blades on the surface of the second rotor body is adjusted, so that the first rotor body and the second rotor body form a mutual cross design. After the water flow hits the blade body, it can naturally impact the blade body on the surface of the second rotor body downward. By increasing the spacing between the blades and adding a multi-layer design, a step-by-step impact is formed. When the water flow is small, the main shaft is also kept at a higher speed.

[0021] In the present invention, the flow rate of the water source inside the chamber changes, and the change is fed back to the control end through the sensor installed inside the water pipe. The control end drives the telescopic rod to extend and retract at the top of the first rotor body by analyzing the water volume. The top of the telescopic rod drives the second fixed ring to move downward. At the same time, the top of the second fixed ring drives the first fixed ring to move downward, allowing the first fixed ring to pull the end of the connecting sleeve. The connecting sleeve itself is a segmented telescopic structure, allowing the second fixed ring to drive the first fixed ring to move downward synchronously. The first fixed ring drives the fixed support leg to slide through the interior of the first rotor body. The end of the fixed support leg applies a certain force to the top of the second rotor body, allowing the second rotor body to slide apart at the bottom end of the first rotor body. At this time, the first rotor body and the second rotor body are divided into two from an integral structure, increasing the number of first rotor bodies and increasing the speed of the transmission main shaft under the same flow rate.

[0022] In the present invention, by driving the telescopic rod to extend and retract at the top of the first rotor body, the top of the telescopic rod drives the second fixed ring to move downward, and at the same time, the top of the second fixed ring drives the first fixed ring to move downward, allowing the first fixed ring to pull the end of the connecting sleeve. The connecting sleeve itself is a segmented telescopic structure, allowing the second fixed ring to drive the first fixed ring to move downward synchronously, and the first fixed ring drives the fixed support leg to slide through the interior of the first rotor body. The end of the fixed support leg applies a certain force to the top of the second rotor body, allowing the second rotor body to slide apart at the bottom end of the first rotor body. At this time, the first rotor body and the second rotor body are divided into two from the integral structure and are staggered with each other, thereby expanding the contact surface of the blades inside the turbine and fully utilizing the kinetic energy of the water flow.

[0023] In the present invention, through the fitting and clamping of gears, the driving rod is driven to rotate. The end of the driving rod is simultaneously connected to the second fixed sleeve. The rotating force of the rotating shaft inside the second fixed sleeve is transmitted to the driving rod, causing the driving rod to deflect at the side end of the second fixed sleeve. The top end of the second fixed sleeve rotates at the side end of the first fixed sleeve, applying a force to the deflector plate and causing the deflector plate to rotate around the fixed shaft. Multiple deflector plates deflect simultaneously. When the water flow rate inside the water inlet pipe is small, multiple deflector plates are controlled to deflect, reducing the distance between the deflector plates, increasing the water flow velocity, and causing the water flow to impact the surface of the blade body downward. The flow velocity can be controlled according to the water flow rate.

[0024] In the present invention, the motor drives the gear set to rotate. The surface of the gear set fits with the gear ring, and the gear set pushes the gear ring to rotate in the opposite direction on the surface of the main shaft, causing the gear ring to drive the connecting sleeve to rotate synchronously. Since the telescopic rod previously drove the second fixed ring to move, separating the first runner body and the second runner body from each other, the limiting block at the top end of the second runner body and the docking cylinder expand and contract with each other. By driving the connecting sleeve to rotate, the connecting sleeve drives the first fixed ring at its end to rotate, causing the first fixed ring to drive the fixed leg to deflect slightly. Since the end of the fixed leg is fixedly connected to the second runner body, the second runner body moves and deflects at the bottom end of the first runner body. The second runner body and the docking cylinder rotate with each other to adjust the position of the blades on the surface of the second runner body. The entire device is automatically controlled by the control terminal at the background.

[0025] In the present invention, by allowing the limiting block and the docking cylinder to slide relative to each other, and at the same time, the limiting block slides inside the docking cylinder, squeezing the top end of the reset rod. When the reset rod expands and contracts, it restricts the movement of the limiting block. When the second runner body follows the first runner body to rotate, the second runner body itself can also align and fit with the bottom end of the first runner body by rotating and lifting, causing the first runner body and the second runner body to overlap and form an integrated state. According to the change in water flow rate, the corresponding number of blades is adjusted to increase the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0036] Embodiment 1:

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present invention provides a technical solution, including a runner chamber 1, a sealing seat ring 11 is fixedly installed at the top end of the runner chamber 1, a fixing frame 16 is fixedly installed inside the sealing seat ring 11, at least two support plates 17 are fixedly installed outside the fixing frame 16, a top plate 14 is fixedly installed at the top end of the sealing seat ring 11, a main shaft 15 is rotatably installed inside the top plate 14, a first runner body 22 is fixedly installed at the bottom end of the main shaft 15, at least two blade bodies 23 are fixedly installed on the surface of the first runner body 22, a second runner body 28 is movably installed at the bottom end of the first runner body 22, at least two guide vanes 21 are rotatably installed inside the sealing seat ring 11, and a fixing shaft 41 is fixedly installed at the bottom end of each guide vane 21;

[0038] Each flow deflector 21 is inclined and installed inside the sealing seat ring 11, and the spacing between each flow deflector 21 is the same. At the same time, the blade body 23 is also installed on the surface of the second runner body 28. The top end of the second runner body 28 fits with the bottom end of the first runner body 22. A docking cylinder 34 is rotatably installed at the top end of the second runner body 28. Two limit blocks 32 are slidably installed at the top end of the docking cylinder 34. A reset rod 33 is fixedly installed at the bottom end of each limit block 32. The second runner body 28 drives the docking cylinder 34 to move, enabling the limit block 32 to slide relative to the docking cylinder 34. At the same time, the limit block 32 slides inside the docking cylinder 34, squeezing the top end of the reset rod 33. When the reset rod 33 expands and contracts, it restricts the movement of the limit block 32. When the second runner body 28 rotates following the first runner body 22, the second runner body 28 can also align and fit with the bottom end of the first runner body 22 through rotation and lifting, causing the first runner body 22 and the second runner body 28 to overlap and form an integrated state;

[0039] The top end of the limit block 32 is fixedly connected to the bottom end of the first runner body 22. The first runner body 22 itself is trapezoidally designed. At least two transmission rods 18 are rotatably installed on the outside of the fixing frame 16. At least two drive boxes 19 are fixedly installed on the inside of each fixing frame 16. A gear set 35 is installed at the side end of each drive box 19. A drive motor is installed inside the drive box 19 and is connected to one side of the gear set 35 through a rotating shaft. A connecting sleeve 24 is arranged on the outside of the main shaft 15. A second fixing ring 29 is rotatably installed at the bottom end of the connecting sleeve 24.

[0040] Working principle: When in use, the top end of the water inlet pipe 12 is connected to a water source through a pipeline. The water source flows through the chamber 13, and the water flow enters the inside of the sealing seat ring 11 under the guidance of the water inlet pipe 12. Since the water inlet pipe 12 itself is bent at an angle, during the flow of the water source, it is subjected to a force and will flow along the inner side of the sealing seat ring 11. Through a plurality of inclined guide plates 21, the water source is concentrated and guided to the top end of the first runner body 22. The flowing water impacts the surface of the blade body 23 downward. Coupled with the curved design of the blade body 23, a force will be exerted on the blade body 23, causing the blade body 23 to drive the first runner body 22 to rotate. At this time, the top end of the first runner body 22 drives the main shaft 15 to rotate. When the flow rate of the water source inside the chamber 13 changes, it is fed back to the control end through a sensor installed inside the water inlet pipe 12. The control end analyzes the water volume and drives the telescopic rod 31 to expand and contract at the top end of the first runner body 22. The top end of the telescopic rod 31 drives the second fixing ring 29 to move downward. At the same time, the top end of the second fixing ring 29 drives the first fixing ring 25 to move downward, causing the first fixing ring 25 to pull the end of the connecting sleeve 24. The connecting sleeve 24 itself is a segmented telescopic structure, enabling the second fixing ring 29 to drive the first fixing ring 25 to move downward synchronously. The first fixing ring 25 drives the fixed leg 27 to slide through the inside of the first runner body 22. The end of the fixed leg 27 exerts a certain force on the top end of the second runner body 28, causing the second runner body 28 to slide and separate at the bottom end of the first runner body 22. At this time, the first runner body 22 and the second runner body 28 are separated from an integral structure into two parts, increasing the number of the first runner bodies 22. At the same flow rate, the speed of the transmission main shaft 15 is increased. At the same time, the top end of the second runner body 28 drives the docking cylinder 34 to move downward, causing the limiting block 32 to slide inside the docking cylinder 34. At the same time, both the docking cylinder 34 and the limiting block 32 stretch both ends of the reset rod 33, increasing the acting force on the docking cylinder 34.

[0041] During use, the blade body 23 continuously applies a force to the first runner body 22, causing the first runner body 22 to drive the main shaft 15 to rotate continuously. The main shaft 15 rotates continuously inside the top plate 14. A fixing frame 16 is installed at the bottom end of the top plate 14 and is fixedly connected to the sealing seat ring 11. The motor drives the gear set 35 to rotate. The surface of the gear set 35 engages with the gear ring 26. The gear set 35 pushes the gear ring 26 to rotate in the opposite direction on the surface of the main shaft 15, causing the gear ring 26 to drive the connecting sleeve 24 to rotate synchronously. Since the telescopic rod 31 previously drove the second fixing ring 29 to move, separating the first runner body 22 and the second runner body 28 from each other, the limiting block 32 at the top of the second runner body 28 expands and contracts with the docking cylinder 34. By driving the connecting sleeve 24 to rotate, the connecting sleeve 24 drives the first fixing ring 25 at the end to rotate, causing the first fixing ring 25 to drive the fixed leg 27 to deflect slightly. Since the end of the fixed leg 27 is fixedly connected to the second runner body 28, the second runner body 28 moves and deflects at the bottom of the first runner body 22. The second runner body 28 rotates with the docking cylinder 34 to adjust the position of the blades on the surface of the second runner body 28, forming an intersecting design between the first runner body 22 and the second runner body 28. After the water flow impacts the blade body 23, it can naturally impact the blade body 23 on the surface of the second runner body 28 downward. By increasing the spacing between the blades and with a multi-layer design, a step-by-step impact is formed. Even when the water flow is small, the main shaft 15 can still rotate at a relatively high speed.

[0042] Embodiment 2:

[0043] Please refer to Figure 6 、 Figure 7 、 Figure 8, on the basis of the first embodiment, the present invention provides a technical solution. At least two telescopic rods 31 are fixedly installed at the bottom end of the second fixing ring 29. A gear ring 26 is fixedly installed at the top end of the connecting sleeve 24. The surface of the gear ring 26 is aligned with a plurality of driving boxes 19. At the same time, the top end of the gear ring 26 is snap-fitted with a gear set 35. A first fixing ring 25 is fixedly installed at the bottom end of the connecting sleeve 24. At least two fixing legs 27 are fixedly installed at the bottom end of the first fixing ring 25. By driving the connecting sleeve 24 to rotate, the connecting sleeve 24 drives the first fixing ring 25 at the end to rotate, so that the first fixing ring 25 drives the fixing legs 27 to deflect slightly. Since the end of the fixing leg 27 is fixedly connected to the second runner body 28, the second runner body 28 moves and deflects at the bottom end of the first runner body 22. The second runner body 28 rotates with the docking cylinder 34 to adjust the position of the blades on the surface of the second runner body 28, so that the first runner body 22 and the second runner body 28 form an intersecting design. After the water flow impacts the blade body 23, it can naturally impact the blade body 23 on the surface of the second runner body 28 downward. By increasing the distance between the blades and adding a multi-layer design, a step-by-step impact is formed;

[0044] A groove 39 is provided on the inner side wall of the sealing seat ring 11. A first fixing sleeve 36 is fixedly installed at the top end of each guide vane 21. A driving rod 37 is rotatably installed at the side end of each first fixing sleeve 36. A second fixing sleeve 38 is provided at the end of each driving rod 37. The end of the second fixing sleeve 38 is fixedly connected to the inner side wall of the groove 39. The end of the second fixing sleeve 38 is also rotatably connected to the corresponding transmission rod 18. A water inlet pipe 12 is fixedly installed on the outside of the sealing seat ring 11. A chamber 13 is provided at the side end of the water inlet pipe 12. The chamber 13 extends to one side and is connected to the inside of the sealing seat ring 11.

[0045] Working principle: The side end of the driving box 19 is rotatably connected to the transmission rod 18. Tapered gears are installed at both ends of the driving box 19. Through the engagement of the gears, the transmission rod 18 is driven to rotate. The end of the transmission rod 18 is also connected to the second fixing sleeve 38. The rotating force of the rotating shaft inside the second fixing sleeve 38 is transmitted to the driving rod 37, so that the driving rod 37 deflects at the side end of the second fixing sleeve 38. The top end of the second fixing sleeve 38 rotates at the side end of the first fixing sleeve 36 to apply a force to the guide vane 21, so that the guide vane 21 rotates around the fixed shaft 41. A plurality of guide vanes 21 deflect simultaneously. When the water flow rate inside the water inlet pipe 12 is small, the plurality of guide vanes 21 are controlled to deflect, so that the distance between the guide vanes 21 is reduced, the water flow velocity is increased, and the water flow impacts the surface of the blade body 23 downward. The flow velocity can be controlled according to the water flow rate, so that the main shaft 15 continuously maintains a high rotation speed.

[0046] When driving the gear ring 26 to rotate through the gear set 35, the gear ring 26 drives the connecting sleeve 24 at the bottom end to rotate synchronously, so that the first runner body 22 rotates. During this process, the connecting sleeve 24 rotates around the outside of the main shaft 15, causing the connecting sleeve 24 to drive a plurality of fixed legs 27 to rotate. The end of the fixed leg 27 is fixedly connected to the top end of the second runner body 28. At the same time, the fixed leg 27 drives the second runner body 28 to rotate at the bottom end of the first runner body 22, aligning the bottom end of the second runner body 28 with the bottom end of the first runner body 22. By driving the telescopic rod 31 to expand and contract, the telescopic rod 31 exerts an upward thrust on the second fixing ring 29, causing the second fixing ring 29 to move upward at the top of the first runner body 22. The first fixing ring 25 pushes the connecting sleeve 24, causing the connecting sleeve 24 to slide and expand and contract around the outside of the main shaft 15. The top end of the second fixing ring 29 pushes the first fixing ring 25 upward. During the deflection process, the first fixing ring 25 synchronously drives the fixed leg 27 to move upward. The second runner body 28 is subjected to the force of the fixed leg 27 and moves upward. The second runner body 28 drives the docking cylinder 34 to move, causing the limiting block 32 and the docking cylinder 34 to slide relative to each other. At the same time, the limiting block 32 slides inside the docking cylinder 34, squeezing the top end of the reset rod 33. When the reset rod 33 expands and contracts, it restricts the movement of the limiting block 32. When the second runner body 28 rotates following the first runner body 22, the second runner body 28 can also align and fit with the bottom end of the first runner body 22 by rotating and lifting, causing the first runner body 22 and the second runner body 28 to overlap and form an integrated state. According to the change in water flow, the corresponding number of blades is adjusted to increase the flexibility of use.
