Description

Technical Field

[0001] This invention belongs to the field of hydropower generation, and specifically relates to a lever-effect V-blade semi-circular horizontal water turbine. Background Technology

[0002] Currently, the more traditional power generation methods in society usually include thermal power generation, hydropower generation, wind power generation, photovoltaic power generation, nuclear power, etc. Among them, hydropower generation is widely used due to its advantages such as low cost, large power generation, and no environmental pollution.

[0003] The water turbine is the core equipment in hydroelectric power generation. Traditional water turbines typically include reaction turbines and impulse turbines. Reaction turbines include mixed-flow, axial-flow, oblique-flow, and through-flow types, while impulse turbines include bucket turbine, oblique-impact, and double-impact types. In current technology, both impulse and reaction turbines utilize the energy of water flow to drive the turbine runner, which in turn drives a generator to produce electricity. This method offers advantages such as low cost and environmental friendliness.

[0004] Reaction turbines and impulse turbines are classified as horizontal or vertical depending on the way the main shaft is set. Existing horizontal turbines generally have the problem of low water resource utilization, which can easily lead to unstable power generation during the dry season. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a lever-effect V-blade semi-circular horizontal water turbine that can utilize the lever effect to improve water resource utilization and thereby enhance the power generation efficiency of the water turbine.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] This invention provides a lever-effect V-blade semi-circular horizontal water turbine, comprising:

[0008] A crescent-shaped housing, wherein the crescent-shaped housing has an internal mounting cavity;

[0009] The base tail water trough is connected at its upper end to the lower end of the crescent-shaped shell, and the base tail water trough has a water discharge trough that communicates with the mounting cavity.

[0010] V-shaped lever wheel, the V-shaped lever wheel includes a wheel disk with lever effect and several V-shaped blades. The wheel disk is disposed in the mounting cavity and located above the water discharge tank. The several V-shaped blades are arranged around the outside of the wheel disk, and the "V" shaped openings of each V-shaped blade are in the same direction.

[0011] The spray structure includes a nozzle, and the crescent-shaped housing is provided with a nozzle mounting port that communicates with the mounting cavity. The nozzle is mounted on the nozzle mounting port, and the nozzle orifice faces the V-shaped blade.

[0012] Electric generator;

[0013] A spindle assembly, comprising a spindle, one end of which passes through a crescent-shaped housing and is connected to the center of a rotary disk, and the other end of which is connected to a generator ball.

[0014] In this application, high-pressure water flow can enter the installation cavity from the nozzle and directly impact the V-shaped blades of the turbine runner, thereby driving the turbine runner to rotate faster. The turbine runner drives the generator bulb through the main shaft to generate hydroelectric power.

[0015] Compared to existing horizontal turbines, this application, by setting a crescent-shaped shell that matches the annular runner for mounting nozzles, shortens the distance between the nozzles and the runner, reducing water flow loss at the nozzles. The V-shaped blades catch the water flow from the nozzles, with the "V"-shaped opening facing upwards, rotating downwards to receive the water flow impact. When the turbine rotates at high speed, the V-shaped blades' V-tip points downwards, both catching the water flow through the "V"-shaped opening to improve water utilization and reducing airflow friction resistance generated during high-speed rotation, thus reducing energy loss and improving energy efficiency. When the V-shaped blades are impacted by the water flow, they drive the runner to rotate. When the V-shaped blades reach the bottom of the runner, the water on them is thrown into the discharge trough at the bottom of the runner, discharging the water and reducing the load on the runner. This creates a lever effect, ensuring high-speed rotation of the runner and improving the turbine's power generation efficiency.

[0016] Furthermore, the crescent-shaped housing includes a left crescent-shaped housing, a left circular housing, an H-shaped rear guide groove housing, an H-shaped jet seat front guide groove housing, a right crescent-shaped housing, and a right circular housing. The left crescent-shaped housing and the right crescent-shaped housing are arranged opposite to each other. The top of the base tailwater trough has a slot for communicating with the installation cavity and the unloading trough. The right crescent-shaped housing is located to the right of the slot, and the bottom surface of the right crescent-shaped housing is fixedly installed on the top of the base tailwater trough. The outer surface of the right circular housing is installed on the inner surface of the right crescent-shaped housing. The left crescent-shaped housing is located on the left side of the slot, and the bottom surface of the left crescent-shaped housing is fixedly installed on the top of the tailwater trough of the base. The outer side of the left circular housing is installed on the inner side of the left crescent-shaped housing. The H-shaped rear guide slot housing is fastened to the inner side of the edges of the right crescent-shaped housing and the left crescent-shaped housing. The H-shaped jet seat front guide slot housing is seamlessly connected to the H-shaped rear guide slot housing and fastened to the inner side of the edges of the right crescent-shaped housing and the left crescent-shaped housing. The nozzle mounting port is opened on the H-shaped jet seat front guide slot housing.

[0017] Furthermore, the rotary disk has a central axis that passes vertically through its center point, the nozzle mounting port is disposed on the front guide groove housing of the H-shaped spray seat, and the angle between the line connecting the nozzle mounting port and the center of the rotary disk and the central axis is between 45 degrees and 130 degrees.

[0018] Furthermore, there are two nozzle mounting ports, one of which is vertically positioned at a 45-degree angle to the central axis, and the other is obliquely positioned at a 105-degree angle to the central axis, so that both nozzle mounting ports are tangent to the outer circumference of the rotary disk.

[0019] In this application, the nozzle is connected to the high-pressure input pipeline of the self-circulating integrated hydraulic station, which can deliver high-pressure water flow to the V-shaped blades on the rotary disc. By setting the nozzle mounting port at 45 degrees and 105 degrees on the central axis of the rotary disc, and with both nozzle mounting ports tangent to the outer circumference of the rotary disc, the weight of the water flow can be avoided from causing resistance to the rotation of the rotary disc, thus maximizing the utilization of the water flow's energy.

[0020] Furthermore, the V-shaped blade includes a first blade plate and a second blade plate. One side of the first blade plate and one side of the second blade plate are connected to form a "V" shape, and the opening of the "V" shape is opposite to the rotation direction of the rotary disk. This structure not only allows the opening of the "V" shape to receive the water flow from the nozzle, but also reduces air resistance by utilizing the tip of the "V" shape, thereby improving energy utilization.

[0021] Furthermore, the V-shaped lever wheel also includes a water-blocking ring. The wheel disc is mounted on the inner wall of the water-blocking ring, and several V-shaped blades are arranged around the center line of the arc surface of the outer circumference of the water-blocking ring, with one end of each V-shaped blade connected to the outer wall of the water-blocking ring. When water flows into the V-shaped blades, the water-blocking ring can cooperate with the V-shaped blades to form a water storage groove, thereby preventing water from flowing out of the V-shaped blades and improving the utilization rate of the water flow.

[0022] Furthermore, the spindle assembly also includes a spindle sleeve, a spindle sleeve fixing flange, and a front bearing cover for the spindle sleeve. Bearings and oil seals are provided at both ends of the spindle sleeve. The inner side of the spindle sleeve fixing flange is fitted to the middle of the outer end face of the right circular housing. The outer end face of the spindle sleeve fixing flange is connected to the inner end face of the spindle sleeve. The outer end face of the spindle sleeve is connected to the front bearing cover for the spindle sleeve. One end of the spindle passes sequentially through the front bearing cover for the spindle sleeve, the spindle sleeve, the spindle sleeve fixing flange, and the right circular housing, connecting to the center of the rotary disk. The bearings are located between the spindle and the spindle sleeve, and the oil seals are located between the spindle and the front bearing cover for the spindle sleeve and the spindle sleeve fixing flange. In this application, the left crescent-shaped housing, the H-shaped rear guide groove housing, the H-shaped jet seat front guide groove housing, and the right crescent-shaped housing are assembled together to form a crescent-shaped structure. The main shaft passes through the center of the right circular housing and is assembled to the center of the main shaft sleeve and the front bearing cover of the main shaft sleeve. The crescent-shaped structure is then connected and fixedly assembled with the tailrace tank of the base to form an integral water turbine. The main shaft of the water turbine is connected to the main shaft of the generator ball. The tailrace tank of the base is installed on the support base to form a complete water turbine generator set. The main shaft sleeve can protect the main shaft and improve the stability of the structure.

[0023] Furthermore, the base tailwater trough is also equipped with a lever-effect drainage structure for removing residual water from the V-shaped blades.

[0024] Furthermore, the lever effect drainage structure includes a lever effect drainage plate disposed on the inner wall of the tailwater trough of the base, and the lever effect drainage plate is provided with a U-shaped slot for the V-shaped blade to pass through.

[0025] Furthermore, the lever effect drainage plate is located on the side of the base tailwater trough near the H-shaped rear guide groove housing, and its length from the nearest end of the base tailwater trough is one-quarter of the total length of the base tailwater trough.

[0026] Furthermore, the lever effect drainage plate is inclined, and its inclination angle is 40-60 degrees.

[0027] Furthermore, a drain plate connected to the lever effect drain plate is provided on the inner wall of the base tailwater trough. A drain trough is formed between the lever effect drain plate, the drain plate and the inner wall of the base tailwater trough. A through hole is provided on the side plate of the base tailwater trough. A lever effect drain pipe is installed on the through hole. One end of the lever effect drain pipe extends into the drain trough and the other end extends out of the base tailwater trough. A vacuum drain motor is also provided inside the lever effect drain pipe. Motor blades are connected to the vacuum drain motor.

[0028] Furthermore, the end of the lever effect drain pipe opposite to the lever effect drain plate is also equipped with a drain port flange, and the pumped water is discharged into the underground water tank through the drain port flange connected to the drain pipe.

[0029] In this application, when the turbine disc rotates, 60% of the water on the V-shaped blades will be directly discharged into the unloading tank when it reaches the bottom, and then flow into the underground water tank; the remaining 40% of the water will rotate under the drive of the V-shaped blades and hit the lever effect drainage plate. The lever effect drainage plate will block 30% of the water and enter the underground water tank. The remaining 10% of the water will continue to rotate with the V-shaped blades. When it rotates to the position of the drainage and emptying tank, a vacuum is created by the vacuum discharge motor. The vacuum discharge motor is intelligently controlled and starts synchronously with the water turbine to discharge the remaining 10% of the water through the lever effect discharge pipe, so that a vacuum is formed in the H-shaped rear guide groove casing. This avoids the residual water flow from causing resistance to the rotation of the turbine disc, so that the turbine disc rotates to the H-shaped rear guide groove casing without any resistance, thereby realizing the lever effect and improving the utilization rate of water energy.

[0030] The beneficial effects of this invention are as follows: Compared with the prior art, this application, by setting a crescent-shaped shell that is adapted to the annular rotating disk for mounting nozzles, can shorten the distance between the nozzle and the rotating disk, reducing water flow loss from the nozzle; the V-shaped blades can receive the water flow ejected from the nozzles, with the "V"-shaped opening of the V-shaped blades facing upwards, receiving the impact of the water flow and rotating downwards. When the turbine rotates at high speed, the V-shaped tip of the V-shaped blades faces downwards, which can both receive the water flow ejected from the nozzles through the "V"-shaped opening, improving the utilization rate of the water flow, and reduce the airflow friction resistance generated during high-speed rotation by using the "V"-shaped tip, thereby reducing energy loss and improving energy utilization; when the V-shaped blades receive the impact of the water flow, they can drive the rotating disk to rotate. When the V-shaped blades rotate to the bottom of the rotating disk, the water on the V-shaped blades will be thrown into the water discharge trough at the bottom of the rotating disk, discharging the water and reducing the load on the rotating disk, giving the rotating disk a lever effect, ensuring the high-speed rotation of the rotating disk, and improving the power generation efficiency of the turbine.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] To achieve the above objectives, the technical solution of the present invention is as follows:

[0040] See Figure 1-6 As shown, this embodiment provides a lever-effect V-blade semi-circular horizontal water turbine, comprising:

[0041] A crescent-shaped housing 1, wherein the crescent-shaped housing 1 has an installation cavity 2 inside;

[0042] The base tail water trough 3 has its upper end connected to the lower end of the crescent-shaped shell 1, and the base tail water trough 3 has a water discharge trough 4 that communicates with the mounting cavity 2.

[0043] V-shaped lever wheel 5, the V-shaped lever wheel 5 includes a wheel disk 51 with lever effect and several V-shaped blades 52. The wheel disk 51 is disposed in the mounting cavity 2 and located above the water discharge tank 4. Several V-shaped blades 52 are arranged around the outside of the wheel disk 51, and the "V" shaped openings of each V-shaped blade 52 are in the same direction.

[0044] The spray structure 6 includes a nozzle 61. The crescent-shaped housing 1 is provided with a nozzle mounting port 62 that communicates with the mounting cavity 2. The nozzle 61 is mounted on the nozzle mounting port 62, and the nozzle 61 faces the V-shaped blade 52.

[0045] 7-cell power generator;

[0046] The main spindle assembly 8 includes a main spindle 81, one end of which passes through the crescent-shaped housing 1 and is connected to the center of the rotary disk 51, and the other end is connected to the generator ball 7.

[0047] In this application, high-pressure water can be sprayed from nozzle 61 into the mounting cavity 2 and directly impact the "V"-shaped opening of the V-shaped blade 52 of the turbine disk 51. The V-shaped blade 52 will rotate under the impact of the water flow, thereby driving the turbine disk 51 to rotate faster. The turbine disk 51 drives the generator ball 7 to work through the main shaft 81 to realize hydroelectric power generation.

[0048] Compared to existing horizontal water turbines, this application features a crescent-shaped housing 1 that matches the shape of the annular impeller 51. The crescent-shaped housing 1 is used to mount the nozzle 61, shortening the distance between the nozzle 61 and the impeller 51 and reducing water flow loss from the nozzle 61. The V-shaped blades 52 have upward-facing openings to receive the water flow from the nozzle 61, rotating downwards to drive the impeller 51 at high speed. When the impeller 51 rotates at high speed, the V-shaped tips of the V-shaped blades 52 point downwards, allowing them to receive the water flow from the nozzle 61 through the V-shaped openings. The ejected water flow improves the utilization rate of the water flow and reduces the airflow friction resistance generated during high-speed rotation by using the "V" shaped tip, thereby reducing energy loss and improving energy utilization. When the V-shaped blade 52 is impacted by the water flow, it can drive the rotor disk 51 to rotate. When the V-shaped blade 52 rotates to the bottom of the rotor disk 51, the water on the V-shaped blade 52 will be thrown into the water discharge trough 4 at the bottom of the rotor disk 51 to discharge the water, reduce the weight of the rotor disk 51, and make the rotor disk 51 have a leverage effect, ensuring that the rotor disk 51 rotates at high speed, which can improve the power generation efficiency of the water turbine.

[0049] Further, the crescent-shaped housing 1 includes a left crescent-shaped housing 11, a left circular housing 12, an H-shaped rear guide groove housing 13, an H-shaped jet seat front guide groove housing 14, a right crescent-shaped housing 15, and a right circular housing 16. The left crescent-shaped housing 11 and the right crescent-shaped housing 15 are arranged opposite to each other. The top of the base tailwater trough 3 has a slot 31 for communicating with the installation cavity 2 and the unloading trough 4. The right crescent-shaped housing 15 is located to the right of the slot 31, and the bottom surface of the right crescent-shaped housing 15 is fixedly installed on the top of the base tailwater trough 3. The outer surface of the right circular housing 16 is installed inside the right crescent-shaped housing 15. On the side, the left crescent-shaped housing 11 is located to the left of the slot 31, and the bottom surface of the left crescent-shaped housing 11 is fixedly installed on the top of the tailwater trough 3 of the base. The outer side of the left circular housing 12 is installed on the inner side of the left crescent-shaped housing 11. The H-shaped rear guide groove housing 13 is fastened to the inner side of the edges of the right crescent-shaped housing 15 and the left crescent-shaped housing 11. The H-shaped jet seat front guide groove housing 14 is seamlessly connected to the H-shaped rear guide groove housing 13 and fastened to the inner side of the edges of the right crescent-shaped housing 15 and the left crescent-shaped housing 11. The nozzle mounting port 62 is opened on the H-shaped jet seat front guide groove housing 14. The above structure facilitates the assembly of the crescent-shaped housing 1, thereby facilitating the installation of the rotary disc 51.

[0050] Furthermore, the rotary disk 51 has a central axis that passes vertically through its center point, the nozzle mounting port 62 is disposed on the front guide groove housing 14 of the H-shaped spray seat, and the angle between the line connecting the nozzle mounting port 62 and the rotary disk 51 and the central axis is between 45 degrees and 130 degrees.

[0051] Furthermore, there are two nozzle mounting ports 62, one of which is vertically positioned at a 45-degree angle to the central axis, and the other is obliquely positioned at a 105-degree angle to the central axis, so that both nozzle mounting ports 62 are tangent to the outer circumference of the rotary disk 51.

[0052] In this application, the nozzle 61 is connected to the high-pressure input injection pipe 63 of the self-circulating integrated hydraulic station, which can deliver high-pressure water flow to the V-shaped blades 52 on the rotary disk 51. By setting the nozzle mounting port 62 at 45 degrees and 105 degrees on the central axis of the rotary disk 51, and with both nozzle mounting ports 62 being tangent to the outer circumference of the rotary disk 51, the weight of the water flow can be avoided from generating resistance to the rotation of the rotary disk 51, thus maximizing the utilization of the water flow energy.

[0053] Furthermore, the V-shaped blade 52 includes a first blade plate 521 and a second blade plate 522. One side of the first blade plate 521 and one side of the second blade plate 522 are connected to form a "V" shape, and the opening of the "V" shape is opposite to the rotation direction of the turntable 51. This structure not only allows the opening of the "V" shape to receive the water flow from the nozzle 61, but also reduces air resistance by utilizing the tip of the "V" shape, thereby improving energy utilization.

[0054] Furthermore, the V-shaped lever wheel 5 also includes a water-blocking ring 53. The wheel disc 51 is mounted on the inner wall of the water-blocking ring 53. Several V-shaped blades 52 are arranged around the center line of the arc surface of the outer circumference of the water-blocking ring 53, and one end of each V-shaped blade 52 is connected to the outer wall of the water-blocking ring 53. When water flows into the V-shaped blades 52, the water-blocking ring 53 can cooperate with the V-shaped blades 52 to form a groove for storing water, thereby preventing water from flowing out of the V-shaped blades 52 and improving the utilization rate of water flow.

[0055] Furthermore, the spindle assembly 8 also includes a spindle sleeve 82, a sleeve fixing flange 83, and a front bearing cover 84. Bearings 85 and oil seals 86 are provided at both ends of the spindle sleeve 82. The inner side of the sleeve fixing flange 83 is fitted to the middle of the outer end face of the right circular housing 16, and the outer end face of the sleeve fixing flange 83 is connected to the inner end face of the spindle sleeve 82. The outer end face of the spindle sleeve 82 is connected to the front bearing cover 84. One end of the spindle 81 passes sequentially through the front bearing cover 84, the spindle sleeve 82, the sleeve fixing flange 83, and the right circular housing 16, connecting to the center of the rotary disk 51. The bearing is located between the spindle 81 and the spindle sleeve 82, and the oil seal 86 is located between the spindle 81 and the front bearing cover 84 and the sleeve fixing flange 83. In this application, the left crescent-shaped housing 11, the H-shaped rear guide groove housing 13, the H-shaped jet seat front guide groove housing 14, and the right crescent-shaped housing 15 are assembled together to form a crescent-shaped structure. The main shaft 81 passes through the center of the right circular housing 16 and is assembled to the center of the main shaft sleeve 82 and the main shaft sleeve front bearing cover 84. The crescent-shaped structure is then connected and fixedly assembled with the base tailrace 3 to form an integral water turbine. The water turbine main shaft 81 is connected to the main shaft of the generator ball 7. The base tailrace 3 is installed on the support base to form a complete water turbine generator set. The main shaft sleeve 82 can protect the main shaft 81 and improve the stability of the structure.

[0056] Furthermore, the base tailwater trough 3 is also equipped with a lever effect drainage structure 9 for removing residual water from the V-shaped blades 52.

[0057] Furthermore, the lever effect drainage structure 9 includes a lever effect drainage plate 91 disposed on the inner wall of the tailwater trough 3 of the base, and the lever effect drainage plate 91 is provided with a U-shaped slot for the V-shaped blade 52 to pass through.

[0058] Furthermore, the lever effect drainage plate 91 is disposed on the side of the base tailwater trough 3 near the H-shaped rear guide groove housing 13, and its length from the nearest end of the base tailwater trough 3 is one-quarter of the total length of the base tailwater trough 3.

[0059] Furthermore, the lever effect drainage plate 91 is inclined, and its inclination angle is 40-60 degrees.

[0060] Furthermore, a drain base plate 92 connected to the lever effect drain plate 91 is also provided on the inner wall of the base tailwater trough 3. A drain trough 93 is formed between the lever effect drain plate 91, the drain base plate 92 and the inner wall of the base tailwater trough 3. A through hole is opened on the side plate of the base tailwater trough 3. A lever effect drain pipe 94 is installed on the through hole. One end of the lever effect drain pipe 94 extends into the drain trough 93 and the other end extends out of the base tailwater trough 3. A vacuum drain motor 95 is also provided in the lever effect drain pipe 94. A motor blade 96 is connected to the vacuum drain motor 95.

[0061] Furthermore, the end of the lever effect drain pipe 94 opposite to the lever effect drain plate 91 is also equipped with a drain port flange 97, and the drain pipe 98 is connected to the drain port flange 97 to discharge the pumped water into the underground water tank.

[0062] In this application, when the rotary disk 51 rotates, 60% of the water on the V-shaped blades 52 will be directly discharged into the unloading tank 4 when it reaches the bottom, and then flow into the underground water tank; the remaining 40% of the water will rotate under the drive of the V-shaped blades 52 and hit the lever effect drainage plate 91. The lever effect drainage plate 91 will block 30% of the water and enter the underground water tank. The remaining 10% of the water will continue to rotate with the V-shaped blades 52. When it rotates to the position of the drainage and emptying tank 93, the vacuum discharge motor 95 will draw a vacuum. The vacuum discharge motor 95 is intelligently controlled and starts to run synchronously with the water turbine, and discharges the remaining 10% of the water through the lever effect discharge pipe 94, so that a vacuum is formed in the H-shaped rear guide groove housing 13, avoiding the resistance of the residual water flow to the rotation of the rotary disk 51. As a result, the rotary disk 51 rotates to the H-shaped rear guide groove housing 13 without any resistance, thereby realizing the lever effect and improving the utilization rate of water energy.

[0063] In this embodiment, a design power of 500KW is taken as an example:

[0064] The diameter of the runner of a traditional water turbine

[0065] The turbine runner diameter in this embodiment

[0066] Nr: Design power: 500KW;

[0067] g: Gravitational acceleration: 9.81;

[0068] The water flow rate Q of a conventional water turbine is 0.018 m³ / h. 3 / s;

[0069] In this embodiment, the water flow rate Q of the lever-effect V-bladed semi-circular horizontal turbine is 0.009 m³. 3 / s;

[0070] H: Water head: 300M;

[0071] δ: Leverage coefficient ≈ 1.45, the value of which was obtained through multiple experiments;

[0072] η: Operating efficiency: 0.904;

[0073] Rotation speed: 1000 r / min.

[0074] As can be seen from the above, under the same conditions, compared with traditional water turbines, when using the lever effect V-blade semi-circular horizontal water turbine of this embodiment for hydropower generation, under the premise of the same design power and speed, the diameter of the runner is smaller, the required water flow is only half that of traditional water turbines, the power generation efficiency is higher, and water resources are more conserved. It can achieve the same electrical energy output as traditional water turbines with less water resources.

[0075] From the perspective of water resource utilization, under the premise of equal head pressure, the water flow required by traditional water turbines is twice that of this implementation. This means that in actual operation, traditional water turbines will consume twice as much water resources, which not only increases the waste of water resources, but also poses a challenge to the sustainable use of water resources.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
