Description

Technical Field

[0001] The present invention relates to the technical field of driving water wheel devices, and particularly to an energy-saving water turbine-driven impeller device. Background Art

[0002] A water turbine is an important energy conversion device that converts the energy of water flow into mechanical energy, and it is also an important core unit for hydropower generation in the utilization of new energy. Existing water turbines mainly include a spiral case, a draft tube, a runner, and a generator. Flowing water enters from the water inlet of the spiral case, forms high-pressure water flow after swirling and accelerating, impacts the runner, and finally is discharged through the draft tube. During this process, the runner is driven to rotate, and then the generator is driven to rotate and generate electricity through a transmission shaft;

[0003] In the prior art, after water enters the water wheel device, due to the influence of the water flow rate, there may be a phenomenon that the water wheel rotates too slowly or too fast; if the water wheel rotates too slowly, the power generation efficiency of the generator is low; if the water wheel rotates too fast, it may cause the generator to be overloaded and malfunction. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving water turbine-driven impeller device to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] An energy-saving water turbine-driven impeller device, comprising: a spiral case, an inlet is provided on the side wall of the spiral case, and an outlet is provided at the bottom of the spiral case; a water wheel device is arranged inside the spiral case, and the water wheel device is used to convert the kinetic energy of water into mechanical energy; a driving device is arranged on the top of the spiral case, and the driving device is used to transmit the mechanical energy generated by the water wheel device; a gearbox is connected to the side of the driving device away from the spiral case, and a generator is connected to the top of the gearbox;

[0007] Water enters the spiral case through the inlet. Subsequently, during the process of water flow, when it encounters the water wheel device, after the water is blocked by the water wheel device, the water pushes the water wheel device to rotate. During the rotation of the water wheel device, the water wheel device converts the kinetic energy of water flow into mechanical energy, and the water wheel device outputs the mechanical energy to the driving device. Under the action of the water wheel device, the driving device rotates. During the rotation of the driving device, the gears in the gearbox are driven to rotate. After the gears are driven step by step, the transmission shaft in the generator is driven to rotate, thereby generating electricity; after the water pushes the water wheel device to rotate, the water wheel device drives the water to flow towards the side close to the outlet, and then the water is discharged out through the outlet.

[0008] Preferably, the water wheel device includes: an outer ring, which is slidably connected to the inner wall of the volute; the outer ring is composed of an upper ring and a lower ring, and blades are arranged between the upper ring and the lower ring. The blades are rotatably connected to the upper ring and the lower ring through rotating rods; an output shaft is arranged at the top of the upper ring, and the output shaft passes through the top of the volute to connect to a driving device; a water channel is opened at the bottom of the lower ring, and the water channel is communicated with the water outlet, and a support frame is arranged in the water channel.

[0009] Water flows into the interior of the volute from the water inlet. During the flowing process of the water, the water encounters the obstruction of the outer ring, and then the water exerts kinetic energy on the surface of the blades. Then, the blades move under the action of the water, and the blades rotate and move around the axis of the outer ring. During the movement of the blades, the upper ring and the lower ring are driven to rotate. During the rotation of the upper ring, the output shaft in the outer ring is driven to rotate, and the output shaft drives the driving device to rotate, realizing the conversion of the kinetic energy of the water into mechanical energy; during the process of the water pushing the blades to move, the water flows from the outside of the outer ring to the inside of the outer ring, and then enters the water channel, flows through the water channel to the water outlet, and finally discharges outward.

[0010] Preferably, the water wheel device further includes: a rotating shaft, which is arranged inside the outer ring. A plurality of fan blades are arranged on the shaft wall of the rotating shaft. One end of the rotating shaft is rotatably connected to the support frame, and the other end of the rotating shaft passes through the top of the upper ring, and the rotating shaft is rotatably connected to the output shaft in the upper ring.

[0011] Preferably, an electromagnet is arranged on one side of the fan blade close to the outer ring; the blade is composed of a magnetic conductor and a non-magnetic body.

[0012] Preferably, the driving device includes: a push cylinder, which is arranged on one side of the gearbox close to the volute. A coupling is arranged on the push rod in the push cylinder, the coupling connects the rotating shaft, a snap ring is arranged on the rotating shaft, and a clamping groove is arranged on the output shaft in the outer ring.

[0013] Preferably, a main gear is arranged on the outer wall of the output shaft in the outer ring, the main gear meshes and drives a driving gear, the driving gear is connected to the gearbox through a push rod transmission shaft, a sub-gear is arranged on one side of the snap ring close to the coupling, and two transmission shafts extend from the bottom of the gearbox. A first driven gear is arranged on the left transmission shaft, and a second driven gear is arranged on the right transmission shaft.

[0014] Preferably, the first driven gear and the second driven gear are in different horizontal planes; the first driven gear is used to drive the rotating shaft to rotate counterclockwise; the second driven gear is used to drive the rotating shaft to rotate clockwise.

[0015] When the flowmeter detects that the water flow is in a steady state, the snap ring and the card slot are in a separated state at this time, and the secondary gear is not engaged with the first driven gear and the second driven gear; when water flows into the volute, the water can only drive the outer ring to rotate, while the fan blades are in a stopped state; when the water flows, it only pushes the outer ring to rotate. During the rotation of the outer ring, the output shaft in the outer ring drives the main gear to rotate. The main gear meshes with and drives the drive gear, and the drive gear drives the transmission shaft in the gearbox to rotate. The transmission shaft drives the gear set in the gearbox to mesh and drive, and the gear set drives the generator to generate electricity;

[0016] When the flowmeter detects that the water flow is small, the controller controls the push cylinder to start. The push cylinder pushes the push rod to move towards the side close to the volute. During the pushing process of the push rod, the push rod drives the coupling to move, the coupling drives the rotating shaft to move, and the rotating shaft drives the snap ring to move. When the snap ring extends into the card slot, the secondary gear on the rotating shaft meshes with the second driven gear at this time. When the water pushes the outer ring to rotate, the outer ring drives the rotating shaft to rotate, and the rotating shaft drives the fan blades to rotate. The rotation direction of the fan blades is the same as that of the blades. During the rotation of the rotating shaft, it drives the secondary gear to rotate. The secondary gear meshes with and drives the second driven gear, and the second driven gear drives the transmission shaft to rotate. The transmission shaft and the transmission shaft together drive the gear set in the gearbox to mesh and drive; this avoids the inability to generate electricity effectively due to small water flow, ensures the stable operation of the generator, and improves the stability of the generator's power generation;

[0017] When the flowmeter detects that the water flow is large, the controller controls the push cylinder to start. The push cylinder drives the push rod to move towards the side away from the card slot, causing the snap ring to disengage from the card slot. Subsequently, the push rod drives the rotating shaft to move, and the rotating shaft drives the secondary gear to move. The secondary gear moves towards the side close to the first driven gear, causing the secondary gear to mesh with and drive the first driven gear. When the water drives the outer ring to rotate and the outer ring rotates clockwise, the rotating shaft rotates in the opposite direction through the gearbox, causing the rotating shaft to rotate counterclockwise. The rotating shaft drives the fan blades to rotate counterclockwise, causing the fan blades to stir the water during rotation, thereby generating a counter - thrust on the outer ring in the counter - clockwise direction inside the outer ring, which slows down the rotation speed of the outer ring, avoids damage to the outer ring in a high - speed rotation state, and at the same time, avoids damage to the gearbox and the generator caused by the high - speed mechanical energy generated by the outer ring, thus ensuring the stable operation of the impeller device and improving the operating stability of the impeller device;

[0018] When the flowmeter detects that the water flow is unstable, the controller controls the electromagnet in the fan blade to be energized. After the electromagnet is energized, it generates a magnetic force. The magnetic force attracts the magnetizable body in the blade, and the magnetizable body generates an offset under the action of the magnetic force, causing the angle of the blade to change. The controller changes the magnitude of the current of the electromagnet through the flow signal detected by the flowmeter, thereby controlling the magnitude of the magnetic force of the electromagnet, and further affecting the rotation angle of the blade; when the flow is large, the angle between the blade and the upper ring and the lower ring decreases; when the flow is small, the angle between the blade and the upper ring and the lower ring increases; thus ensuring the stable rotation of the outer ring.

[0019] Preferably, a flowmeter is arranged in the water inlet, and the flowmeter is used to detect the magnitude of the water flow entering the impeller device;

[0020] Water enters the impeller device through the water inlet. During the process of water entry, the controller controls the flowmeter in the water inlet to start. The flowmeter detects the water flow, and the flowmeter converts the flow signal into an electrical signal and transmits it to the controller. The controller controls the driving device to adjust the rotating shaft to ensure the stable operation of the generator, so that the generator can output electricity stably.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0022] 1. When the flowmeter detects that the water flow is small, when the water drives the outer ring to rotate, the outer ring drives the rotating shaft to rotate, the rotating shaft drives the fan blade to rotate, so that the rotation direction of the fan blade is the same as the rotation direction of the blade. During the rotation of the rotating shaft, the driven gear is driven to rotate, the driven gear meshes with and drives the second driven gear, and the second driven gear drives the transmission shaft to rotate, and the transmission shaft drives the gear set in the gearbox to mesh and drive; it avoids the inability to generate electricity effectively due to small water flow, ensures the stable operation of the generator, and improves the stability of the generator's power generation.

[0023] 2. When the flowmeter detects that the water flow is large, when the water drives the outer ring to rotate and the outer ring rotates clockwise, the rotating shaft rotates in the opposite direction through the gearbox, so that the rotating shaft rotates counterclockwise. The rotating shaft drives the fan blade to rotate counterclockwise, so that during the rotation of the fan blade, the water is stirred, thereby generating a counterclockwise counterthrust on the outer ring inside the outer ring, thereby slowing down the rotation speed of the outer ring, avoiding damage to the outer ring in the state of high-speed rotation, and at the same time, avoiding damage to the gearbox and the generator caused by the high-speed mechanical energy generated by the outer ring, thus ensuring the stable operation of the impeller device and improving the operation stability of the impeller device.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0036] An energy-saving water turbine driving impeller device, comprising: a spiral case 1, a water inlet 11 is arranged on the side wall of the spiral case 1, and a water outlet 12 is arranged at the bottom of the spiral case 1; a water wheel device 2 is arranged inside the spiral case 1, and the water wheel device 2 is used to convert the kinetic energy of water into mechanical energy; a driving device 3 is arranged on the top of the spiral case 1, and the driving device 3 is used to transmit the mechanical energy generated by the water wheel device 2; a gear box 13 is connected to the side of the driving device 3 away from the spiral case 1, and a generator is connected to the top of the gear box 13;

[0037] Water enters the volute 1 through the water inlet 11. Subsequently, during the process of water flow, it encounters the water wheel device 2. After the water is blocked by the water wheel device 2, the water pushes the water wheel device 2 to rotate. During the rotation of the water wheel device 2, the water wheel device 2 converts the kinetic energy of the water flow into mechanical energy. The water wheel device 2 outputs the mechanical energy to the driving device 3. Under the action of the water wheel device 2, the driving device 3 starts to rotate. During the rotation of the driving device 3, it drives the gear transmission in the gearbox 13. After the gears are transmitted step by step, it drives the transmission shaft in the generator to rotate, thereby generating electricity. After the water pushes the water wheel device 2 to rotate, the water wheel device 2 drives the water to flow towards the side close to the water outlet 12, and then the water is discharged outwards through the water outlet 12.

[0038] As a specific embodiment of the present invention, the water wheel device 2 includes: an outer ring 21, and the outer ring 21 is slidably connected to the inner wall of the volute 1; the outer ring 21 is composed of an upper ring 22 and a lower ring 23. Between the upper ring 22 and the lower ring 23, there are blades 24, and the blades 24 are rotatably connected to the upper ring 22 and the lower ring 23 through rotating rods; at the top of the upper ring 22, there is an output shaft, and the output shaft passes through the top of the volute 1 to connect to the driving device 3; at the bottom of the lower ring 23, there is a water channel 231, and the water channel 231 is communicated with the water outlet 12, and a support frame is arranged in the water channel 231.

[0039] Water flows into the interior of the volute 1 from the water inlet 11. During the process of water flow, the water encounters the obstruction of the outer ring 21. Subsequently, the water exerts kinetic energy on the surface of the blade 24. Then, the blade 24 moves under the action of the water. The blade 24 rotates and moves around the axis of the outer ring 21. During the movement of the blade 24, it drives the upper ring 22 and the lower ring 23 to rotate. During the rotation of the upper ring 22, it drives the output shaft in the outer ring 21 to rotate, and the output shaft drives the driving device 3 to rotate, realizing the conversion of the kinetic energy of the water into mechanical energy. During the process of the water pushing the blade 24 to move, the water flows from the outside of the outer ring 21 to the inside of the outer ring 21, then enters the water channel 231, flows through the water channel 231 to the water outlet 12, and is finally discharged outwards.

[0040] As a specific embodiment of the present invention, the water wheel device 2 further includes: a rotating shaft 25, and the rotating shaft 25 is arranged inside the outer ring 21. On the shaft wall of the rotating shaft 25, there are several fan blades 26. One end of the rotating shaft 25 is rotatably connected to the support frame, and the other end of the rotating shaft 25 passes through the top of the upper ring 22 and is rotatably connected to the output shaft in the upper ring 22.

[0041] As a specific embodiment of the present invention, an electromagnet is arranged on the side of the fan blade 26 close to the outer ring 21; the blade 24 is composed of a magnetic conductor and a non-magnetic body.

[0042] As a specific embodiment of the present invention, the driving device 3 includes: a push cylinder 31, which is arranged on one side of the gearbox 13 close to the volute 1. A coupling 32 is arranged on the push rod in the push cylinder 31. The coupling 32 is connected to a rotating shaft 25. A snap ring 33 is arranged on the rotating shaft 25, and a clamping groove 34 is arranged on the output shaft in the outer ring 21.

[0043] As a specific embodiment of the present invention, a main gear 35 is arranged on the outer wall of the output shaft in the outer ring 21. The main gear 35 meshes and drives a driving gear 36. The driving gear 36 is connected to the gearbox 13 through a push rod transmission shaft. A secondary gear 37 is arranged on one side of the snap ring 33 close to the coupling 32. Two transmission shafts extend from the bottom of the gearbox 13. A first driven gear 38 is arranged on the left transmission shaft, and a second driven gear 39 is arranged on the right transmission shaft.

[0044] As a specific embodiment of the present invention, the first driven gear 38 and the second driven gear 39 are in different horizontal planes; the first driven gear 38 is used to drive the rotating shaft 25 to rotate counterclockwise; the second driven gear 39 is used to drive the rotating shaft 25 to rotate clockwise.

[0045] When the flowmeter detects that the water flow is in a stable state, at this time, the snap ring 33 and the clamping groove 34 are in a separated state, and the secondary gear 37 is not meshed with the first driven gear 38 and the second driven gear 39; when water flows into the volute 1, the water can only drive the outer ring 21 to rotate, while the fan blade 26 is in a stopped state; when the water flows, it only pushes the outer ring 21 to rotate. During the rotation of the outer ring 21, the output shaft in the outer ring 21 drives the main gear 35 to rotate. The main gear 35 meshes and drives the driving gear 36. The driving gear 36 drives the transmission shaft in the gearbox 13 to rotate. The transmission shaft drives the gear set in the gearbox 13 to mesh and drive, and the gear set drives the generator to generate electricity;

[0046] When the flowmeter detects that the water flow is small, the controller controls the push cylinder 31 to start. The push cylinder 31 pushes the push rod to move towards the side close to the volute 1. During the pushing process of the push rod, the push rod drives the coupling 32 to move. The coupling 32 drives the rotating shaft 25 to move. The rotating shaft 25 drives the snap ring 33 to move. When the snap ring 33 extends into the clamping groove 34, at this time, the secondary gear 37 on the rotating shaft 25 meshes with the second driven gear 39. When the water pushes the outer ring 21 to rotate, the outer ring 21 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the fan blade 26 to rotate, so that the rotation direction of the fan blade 26 is the same as that of the blade 24. During the rotation of the rotating shaft 25, it drives the secondary gear 37 to rotate. The secondary gear 37 meshes and drives the second driven gear 39. The second driven gear 39 drives the transmission shaft to rotate. The transmission shaft also drives the gear set in the gearbox 13 to mesh and drive; to avoid ineffective power generation due to small water flow;

[0047] When the flowmeter detects that the water flow rate is large, the controller controls the push cylinder 31 to start. The push cylinder 31 drives the push rod to move to the side away from the card slot 34, causing the snap ring 33 to disengage from the card slot 34. Subsequently, the push rod drives the rotating shaft 25 to move, and the rotating shaft 25 drives the secondary gear 37 to move. The secondary gear 37 moves towards the side close to the first driven gear 38, causing the secondary gear 37 to mesh and drive with the first driven gear 38. When the water drives the outer ring 21 to rotate and the outer ring 21 rotates clockwise, the rotating shaft 25 rotates in the opposite direction through the gearbox 13, causing the rotating shaft 25 to rotate counterclockwise. The rotating shaft 25 drives the fan blade 26 to rotate counterclockwise. When the fan blade 26 rotates, it drives the water to stir, thereby generating a counterclockwise counterthrust on the outer ring 21 inside the outer ring 21, which slows down the rotation speed of the outer ring 21, avoids damage to the outer ring 21 in the state of high-speed rotation, and at the same time, avoids damage to the gearbox 13 and the generator caused by the high-speed mechanical energy generated by the outer ring 21;

[0048] When the flowmeter detects that the water flow rate is unstable, the controller controls the electromagnet in the fan blade 26 to be energized. After the electromagnet is energized, it generates a magnetic force. The magnetic force attracts the magnetically permeable body in the blade 24, and the magnetically permeable body generates an offset under the action of the magnetic force, causing the angle of the blade 24 to change. The controller changes the magnitude of the current of the electromagnet through the flow signal detected by the flowmeter, thereby controlling the magnitude of the magnetic force of the electromagnet, and further affecting the rotation angle of the blade 24; when the flow rate is large, the angle between the blade 24 and the upper ring 22 and the lower ring 23 decreases; when the flow rate is small, the angle between the blade 24 and the upper ring 22 and the lower ring 23 increases; thus ensuring the stable rotation of the outer ring 21.

[0049] As a specific embodiment of the present invention, a flowmeter is provided in the water inlet 11, and the flowmeter is used to detect the magnitude of the water flow rate entering the impeller device;

[0050] Water enters the impeller device through the water inlet 11. During the process of water entry, the controller controls the flowmeter in the water inlet 11 to start. The flowmeter detects the water flow rate, and the flowmeter converts the flow signal into an electrical signal and transmits it to the controller. The controller controls the driving device 3 to adjust the rotating shaft 25 to ensure the stable operation of the generator, so that the generator can output electricity stably.

[0051] The working principle of the present invention:

[0052] Water enters the impeller device through the water inlet 11. During the process of water entry, the controller controls the flowmeter in the water inlet 11 to start. The flowmeter detects the water flow rate, and the flowmeter converts the flow signal into an electrical signal and transmits it to the controller. The controller controls the driving device 3 to adjust the rotating shaft 25;

[0053] When the flowmeter detects that the water flow is in a stable state, the snap ring 33 and the slot 34 are in a separated state at this time, and the secondary gear 37 is not engaged with the first driven gear 38 and the second driven gear 39; when water flows into the volute 1, the water can only drive the outer ring 21 to rotate, while the fan blade 26 is in a stopped state; when the water flows, it only pushes the outer ring 21 to rotate. During the rotation of the outer ring 21, the output shaft in the outer ring 21 drives the main gear 35 to rotate. The main gear 35 meshes with and drives the drive gear 36. The drive gear 36 drives the transmission shaft in the gearbox 13 to rotate. The transmission shaft drives the gear set in the gearbox 13 to mesh and drive, and the gear set drives the generator to generate electricity;

[0054] When the flowmeter detects that the water flow is small, the controller controls the push cylinder 31 to start. The push cylinder 31 pushes the push rod to move towards the side close to the volute 1. During the pushing process of the push rod, the push rod drives the coupling 32 to move. The coupling 32 drives the rotating shaft 25 to move. The rotating shaft 25 drives the snap ring 33 to move. When the snap ring 33 extends into the slot 34, at this time, the secondary gear 37 on the rotating shaft 25 meshes with the second driven gear 39. When the water drives the outer ring 21 to rotate, the outer ring 21 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the fan blade 26 to rotate, so that the rotation direction of the fan blade 26 is the same as that of the blade 24. During the rotation of the rotating shaft 25, it drives the secondary gear 37 to rotate. The secondary gear 37 meshes with and drives the second driven gear 39. The second driven gear 39 drives the transmission shaft to rotate. The transmission shaft also drives the gear set in the gearbox 13 to mesh and drive; to avoid ineffective power generation due to small water flow;

[0055] When the flowmeter detects that the water flow is large, the controller controls the push cylinder 31 to start. The push cylinder 31 drives the push rod to move towards the side away from the slot 34, so that the snap ring 33 disengages from the slot 34. Subsequently, the push rod drives the rotating shaft 25 to move. The rotating shaft 25 drives the secondary gear 37 to move. The secondary gear 37 moves towards the side close to the first driven gear 38, so that the secondary gear 37 meshes with and drives the first driven gear 38. When the water drives the outer ring 21 to rotate and the outer ring 21 rotates clockwise, the rotating shaft 25 rotates in the opposite direction through the gearbox 13, so that the rotating shaft 25 rotates counterclockwise. The rotating shaft 25 drives the fan blade 26 to rotate counterclockwise, so that during the rotation of the fan blade 26, it drives the water to stir, thereby generating a counter-thrust force on the outer ring 21 inside the outer ring 21 in the counterclockwise direction, thereby slowing down the rotation speed of the outer ring 21, avoiding damage to the outer ring 21 in the state of high-speed rotation, and at the same time, avoiding damage to the gearbox 13 and the generator caused by the high-speed mechanical energy generated by the outer ring 21;

[0056] When the flowmeter detects that the water flow is unstable, the controller controls the electromagnet in the fan blade 26 to be energized. After the electromagnet is energized, a magnetic force is generated. The magnetic force attracts the magnetizable body in the blade 24, and the magnetizable body generates an offset under the action of the magnetic force, causing the angle of the blade 24 to change. The controller changes the magnitude of the current of the electromagnet through the flow signal detected by the flowmeter, thereby controlling the magnitude of the magnetic force of the electromagnet, and further affecting the rotation angle of the blade 24. When the flow is large, the included angle between the blade 24 and the upper ring 22 and the lower ring 23 decreases; when the flow is small, the included angle between the blade 24 and the upper ring 22 and the lower ring 23 increases.

[0057] After the waterwheel device 2 is rotated by the water, the waterwheel device 2 drives the water to flow toward the side close to the water outlet 12, and then the water is discharged outward through the water outlet 12.
