Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and in particular relates to a three-layer vertical axis dual-channel wind turbine. Background Art

[0002] The vertical axis wind turbines currently on the market use either resistance-type blades or lift-type blades. Resistance-type blades have a fast starting speed, but are limited by wind speed and have low torque, making it difficult to reach a higher speed. Lift-type blades have a higher wind speed but start slower, resulting in low overall wind energy utilization, low power generation, and high starting resistance in vertical axis wind turbines. This is also the reason why vertical axes are difficult to promote and use on a large scale. Summary of the Invention

[0003] In response to the above problems, the present invention provides a three-layer vertical axis dual-channel wind turbine to solve the problems of vertical axis wind turbines currently on the market, such as low wind energy utilization, low power generation, large starting resistance, and difficulty in large-scale promotion.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A three-layer vertical axis dual-channel wind turbine, comprising a main power generation assembly and a secondary power generation assembly; the main power generation assembly comprises an inner coil frame, a magnet frame, and an outer coil frame coaxially arranged on a main shaft and capable of relative rotation; the inner coil frame is sleeved within the magnet frame; the magnet frame is sleeved within the outer coil frame; the outer coil frame is driven to rotate by main wind blades on the outer wall; the outer coil frame drives the magnet frame to rotate via a first magnetic gear transmission assembly;

[0006] The auxiliary power generation assembly is arranged at both ends of the main power generation assembly; the auxiliary power generation assembly includes a rotating frame rotatably arranged on the main shaft; the rotating frame is driven to rotate by the auxiliary fan blades on the outer wall; the rotating frame drives the outer coil frame to rotate through the second magnetic gear transmission assembly.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. The channel is added so that there are coil windings on both sides of the permanent magnet poles of the magnet frame, making full use of the permanent magnet resources. Compared with the original single winding, the winding length is nearly doubled, which significantly improves the power generation efficiency of the vertical axis wind turbine.

[0009] 2. The outer coil accelerates the middle permanent magnet layer through the magnetic gear, forming a differential speed. For example, when the outer layer rotates at 100 rpm and the magnetic gear transmission ratio is 1:3, the speed of the middle permanent magnet is 300 rpm. The actual speed at which the outer coil cuts the magnetic lines of force is 400 rpm. The inner coil is stationary, so the speed at which it cuts the magnetic lines of force is 300 rpm, which is the speed of the middle permanent magnet. Therefore, the relative rotation significantly increases the speed at which the magnetic lines of force are cut, thereby improving the power generation efficiency.

[0010] 3. Assisted startup and continuously maintain the speed of the main fan blades. Generally, the lift-type blades have a high tip speed ratio but are difficult to start. There are also lift-type blades and resistance-type blades that are directly connected on the market. This only solves the startup problem, but after the blade speed increases, it will seriously hinder the further increase of the main blade speed, thereby affecting the efficiency of the entire machine. This design drives the lift-type main blades through magnetic gears with the resistance-type blades. Generally, the tip speed ratio of the resistance-type blades is less than 0.9, and the tip speed ratio of the lift-type blades can be around 4. In this way, the transmission ratio is set to around 1:4. In addition to starting, the resistance-type blades can also provide continuous power to the main blades during operation (considering wind resistance and stable operation, a ratio of around 1:2 is more appropriate).

[0011] 4. The brake block speed-limiting brake device moves outward when the speed exceeds a certain value, contacting the brake disc and slowing the blades. This prevents excessive current from damaging the generator. When the speed decreases, the centrifugal force decreases, causing the brake block to move inward, resuming normal operation. This device features a simple structure, requires no power, operates automatically, and is safe and reliable.

[0012] 5. The use of magnetic gear acceleration increases the relative movement speed of the coil and greatly improves the power generation.

[0013] 6. Compared with traditional mechanical gears, magnetic gears have the following advantages: no wear, smooth operation without noise, no maintenance, and low equipment investment cost.

[0014] 7. Except for the bearings and the guide brushes (except the brake speed limiter), the entire set of equipment has no direct contact parts, which avoids wear and lubrication, requires almost no maintenance, and greatly reduces investment and operation and maintenance costs.

[0015] As a further improvement of the above scheme, the first magnetic gear transmission assembly includes an active magnet disk arranged at the end of the outer coil frame; a driven magnet disk arranged at the end of the magnet frame; a magnetizing disk arranged between the active magnet disk and the driven magnet disk; the driven magnet disk is driven to rotate by the active magnet disk.

[0016] The technical effect of the above improvement is that when the outer coil frame rotates, the magnetic force is transmitted to the driven magnet disk through the magnetizer disk, thereby driving the driven magnet disk to rotate.

[0017] As a further improvement of the above solution, the active magnetic disk, the driven magnetic disk and the magnetizer disk are all disc-shaped; magnet blocks are distributed in an annular shape on the active magnetic disk and the driven magnetic disk; and magnetic conductors are distributed in an annular shape on the magnetizer disk.

[0018] The technical effect of the above improvement is: to concretize the structure of the first magnetic gear transmission assembly, wherein the magnetic conductor is generally a magnetic silicon steel body.

[0019] As a further improvement of the above scheme, the second magnetic gear transmission assembly includes a driven magnet frame arranged at the end of the outer coil frame, a magnetizing frame arranged on the main shaft, which covers the driven magnet frame, and a rotating frame which covers the magnetizing frame; the driven magnet frame is driven to rotate by the rotating frame.

[0020] The technical effect of the above improvement is: the rotating frame is driven to rotate by the auxiliary fan blades, and the rotating frame transmits magnetic force to the driven magnet frame through the magnetizer frame, thereby driving the driven magnet frame to rotate, thereby driving the outer coil frame to rotate.

[0021] As a further improvement of the above solution, the rotating frame, the magnetizing frame and the driven magnet frame are all cylindrical, and magnets are evenly distributed on the side walls of the rotating frame and the driven magnet frame; and magnetic conductors are evenly distributed on the side walls of the magnetizing frame.

[0022] The technical effect of the above improvement is: to concretize the structure of the second magnetic gear transmission assembly, wherein the magnetic conductor is generally a magnetic silicon steel body.

[0023] As a further improvement of the above solution, a brake disc is provided on the main shaft; a slide rod is radially provided on the rotating frame; a slidable centrifugal frame is provided on the slide rod; a brake block for braking the brake disc is provided on the centrifugal frame; and a spring for preventing the centrifugal frame from moving toward the brake disc is provided on the slide rod.

[0024] The technical effect of this improvement is that when the rotational speed exceeds a certain value, the brake block moves outward and contacts the brake disc, thereby slowing the blades and preventing damage to the generator caused by excessive current due to excessive speed. When the speed decreases, the centrifugal force decreases, causing the brake block to move inward, and normal operation resumes. This device has a simple structure, requires no power, operates automatically, and is safe and reliable.

[0025] As a further improvement of the above solution, an outer coil is distributed on the side wall of the outer coil frame; an inner coil is distributed on the side wall of the inner coil frame; and a permanent magnet is distributed on the side wall of the magnet frame.

[0026] The technical effect of the above improvement is: there are coil windings on both sides of the middle layer permanent magnet poles, which fully utilizes the permanent magnet resources. Compared with the original single winding, the winding length is nearly doubled, which significantly improves the power generation efficiency of the vertical axis wind turbine.

[0027] As a further improvement of the above solution, the outer wall of the outer coil frame is covered with a protective tube.

[0028] The technical effect of the above improvement is that the components inside the outer coil frame, including the outer coil, are protected by the protective tube.

[0029] As a further improvement of the above solution, the main fan blade is a Darrieus fan blade.

[0030] The technical effect of the above improvement is that the Darrieus wind blade is a lift-type blade, and the high tip speed ratio can improve the utilization rate of wind energy.

[0031] As a further improvement of the above solution, the auxiliary fan blade is a resistance-type fan blade.

[0032] The technical effect of the above improvement is: this design drives the lift-type main blades through the resistance-type blades through magnetic gears. Generally, the tip speed ratio of the resistance-type blades is less than 0.9, and the tip speed ratio of the lift-type blades can be about 4. In this way, the transmission ratio is set to about 1:4. In addition to starting, the resistance-type blades can also provide continuous power to the main blades during operation (considering wind resistance and operational stability, a ratio of about 1:2 is more appropriate).

[0033] As a further improvement of the above solution, the outer coil frame includes two ring bodies at the ends, and active magnetic disks are arranged inside the ring bodies; the ring bodies are connected to each other by connecting rods; a through hole is opened in the center of the active magnetic disk for the main shaft to pass through.

[0034] The technical effect of the above improvement is: the active magnet disk is fixedly installed through the ring body, the outer coil is installed between the ring bodies, and the connecting rod is used to connect the two ring bodies.

[0035] As a further improvement of the above solution, a photoelectric sensor for sensing speed is provided on the edge of one of the through holes.

[0036] The technical effect of the above improvement is: the rotation speed of the outer coil frame is sensed by the photoelectric sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See also Figures 1 to 12 In a specific embodiment, a three-layer vertical axis dual-channel wind turbine includes a main power generation assembly and an auxiliary power generation assembly; the main power generation assembly includes an inner coil frame 10, a magnet frame 6, and an outer coil frame 5 coaxially arranged on the main shaft and capable of relative rotation; the inner coil frame 10 is sleeved within the magnet frame 6; the magnet frame 6 is sleeved within the outer coil frame 5; the outer coil frame 5 is driven to rotate by main wind blades 9 on the outer wall; the outer coil frame 5 drives the magnet frame 6 to rotate via a first magnetic gear transmission assembly;

[0055] Specifically, the auxiliary power generation assembly is used to assist in driving the main power generation assembly to rotate. The wind drives the auxiliary blades 4 to rotate, thereby driving the rotating frame 3 to rotate. When the rotating frame 3 rotates forward, the outer coil frame 5 rotates in the reverse direction.

[0056] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the first magnetic gear transmission assembly includes an active magnetic disk 51 arranged at the end of the outer coil frame 5; a driven magnetic disk 13 arranged at the end of the magnet frame 6; a magnetizing disk 12 arranged between the active magnetic disk 51 and the driven magnetic disk 13; and the driven magnetic disk 13 is driven to rotate by the active magnetic disk 51.

[0057] Specifically, active magnetic disks 51 are installed at both ends of the outer coil frame 5, and driven magnetic disks 13 are installed at both ends of the magnet frame 6; there is a magnetizing disk 12 between the corresponding active magnetic disks 51 and the driven magnetic disks 13; when the driven magnetic disk 13 rotates forward, the active magnetic disk 51 rotates in the reverse direction.

[0058] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the active magnetic disk 51, the driven magnetic disk 13, and the magnetizing disk 12 are all disc-shaped; the active magnetic disk 51 and the driven magnetic disk 13 are provided with radially extended magnet blocks distributed in a ring shape; the magnetizing disk 12 is provided with radially extended magnetic conductors distributed in a ring shape.

[0059] Specifically, the active magnetic disk 51 has a through hole at the center of both the active and passive magnetic disks 13. The magnet strips on the active and passive magnetic disks 51 and 13 are radially distributed in a circular pattern. The magnetizer on the magnetizer disk 12 is typically made of magnetic silicon steel. The magnet blocks on the active and passive magnetic disks 51 and 13 are evenly distributed in a circular pattern. The number and size of the magnet blocks on the active and passive magnetic disks 51 and 13 can differ, thereby achieving a differential effect.

[0060] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the second magnetic gear transmission assembly includes a driven magnet frame 17 arranged at the end of the outer coil frame 5, a magnetizer frame 16 arranged on the main shaft 1, which is covered with the driven magnet frame 17, and a rotating frame 3 which is covered with the magnetizer frame 16; the driven magnet frame 17 is driven to rotate by the rotating frame 3.

[0061] Specifically, the driven magnet frame 17 is fixedly connected to the outer coil frame 5 , and when the rotating frame 3 rotates forward, the driven magnet frame 17 rotates backward.

[0062] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the rotating frame 3, the magnetizing frame 16, and the driven magnet frame 17 are all cylindrical, and vertical strip-shaped magnets are evenly distributed on the side walls of the rotating frame 3 and the driven magnet frame 17; vertical strip-shaped magnetic conductors are evenly distributed on the side walls of the magnetizing frame 16.

[0063] The magnet blocks on the rotating frame 3 and the driven magnet frame 17 are evenly distributed in a ring shape. The number or size of the magnet blocks on the rotating frame 3 and the driven magnet frame 17 can be different, thereby achieving a differential transmission effect.

[0064] Specifically, the magnetic conductor is a magnetic metal material, which may be a ferromagnetic material or a silicon steel body.

[0065] like Figure 1-4 As shown, as a preferred embodiment of the above embodiment, a brake disc 2 is provided on the main shaft 1; a slide rod is radially provided on the rotating frame 3; a slidable centrifugal frame 18 is provided on the slide rod; a brake block 19 for braking the brake disc 2 is provided on the centrifugal frame 18; and a spring for preventing the centrifugal frame 18 from moving toward the brake disc 2 is provided on the slide rod.

[0066] Specifically, the brake disc 2 is annular and fixed on the main shaft 1. A slide rod is installed radially inside the rotating frame 3, and a slidable centrifugal frame 18 is installed on the slide rod. A brake block 19 is installed on the upper end of the centrifugal frame 18. The brake block 19 is moved away from the brake disc 2 under the action of the spring. When the rotating frame 3 rotates too fast and the centrifugal force exceeds the spring force, the brake block 19 moves closer to the brake disc 2 as the centrifugal frame 18 moves, and finally reduces the speed of the rotating frame 3.

[0067] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, outer coils 7 are distributed on the side walls of the outer coil frame 5; inner coils 11 are distributed on the side walls of the inner coil frame 10; and permanent magnets 8 are distributed on the side walls of the magnet frame 6.

[0069] Specifically, the protective tube 21 is cylindrical and is sleeved on the outer coil frame 5 to play an isolation and protection role. The protective tube 21 can be fixed on the outer coil frame 5 by bolts.

[0070] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the auxiliary fan blade 4 is a resistance type fan blade.

[0071] Specifically, the auxiliary fan blade 4 has a V-shaped structure.

[0072] like Figure 1-12 As shown, as a preferred embodiment of the above embodiment, the outer coil frame 5 includes two ring bodies at the ends, and an active magnetic disk 51 is provided in the ring body; the ring bodies are connected to each other by connecting rods; a through hole is provided in the center of the active magnetic disk 51 for the main shaft 1 to pass through.

[0073] Specifically, there are three connecting rods, and the outer coil 7 is installed between the connecting rods; the support structure of the magnet frame 6 is the same as the support structure of the inner coil frame 10.

[0074] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a photoelectric sensor 52 for sensing speed is provided at the edge of one of the through holes.

[0075] Specifically, three photoelectric sensors 52 are conveniently installed in the center hole at the bottom of the outer coil frame 5 , and are used to cooperate with the light shielding sheet on the main shaft 1 to sense the rotation speed of the outer coil frame 5 .

[0076] The specific working principle of the present invention is:

[0077] The main wind blades 9 drive the outer coil frame 5 to rotate, and the active magnetic disk 51 at the end of the outer coil frame 5 drives the driven magnetic disk 13 to rotate, thereby driving the magnet frame 6 to rotate; the outer coil frame 5, the magnet frame 6 and the inner coil frame 10 constitute a power generation component, the magnet frame 6 constitutes the middle layer permanent magnet 8, and the outer coil frame 5 and the inner coil frame 10 constitute the coil windings on both sides of the magnetic pole, making full use of the permanent magnet 8 resources. Compared with the original single winding, the winding length is increased by nearly one-fold, which significantly improves the power generation efficiency of the vertical axis wind turbine.

[0078] The outer coil 7 accelerates the middle permanent magnet 8 through the magnetic gear to form a differential speed. For example, when the speed of the outer coil 7 is 100 rpm and the magnetic gear transmission ratio is 1:3, the speed of the middle permanent magnet 8 is 300 rpm. The actual speed of the outer coil 7 cutting the magnetic lines of force is 400 rpm. The inner coil 11 is stationary, so the speed of cutting the magnetic lines of force is 300 rpm, which is the speed of the middle permanent magnet 8. Therefore, the relative rotation significantly increases the speed of cutting the magnetic lines of force, thereby improving the power generation efficiency.

[0079] The auxiliary fan blades 4 drive the rotating frame 3 to rotate, and the rotating frame 3 drives the driven magnet frame 17 to rotate through the second magnetic gear assembly, and the driven magnet frame 17 in turn drives the outer coil frame 5 to rotate; it constitutes auxiliary starting, auxiliary starting, and continuously maintains the rotation speed of the main fan blades 9. Generally, the tip speed ratio of lift-type blades is high but difficult to start. There are also lift-type blades and resistance-type blades directly connected on the market, which only solves the problem of starting. However, after the blade speed increases, it will seriously hinder the further increase of the main blade speed, thereby affecting the efficiency of the whole machine. This design drives the lift-type main blades through magnetic gears with the resistance-type blades. Generally, the tip speed ratio of the resistance-type blades is less than 0.9, and the tip speed ratio of the lift-type blades can be about 4. In this way, the transmission ratio is set to about 1:4. In addition to starting, the resistance-type blades can also provide continuous power to the main blades during operation (actually considering wind resistance and stable operation, a ratio of about 1:2 is more appropriate).

[0080] Brake block 19 is a speed-limiting brake device. When the rotational speed of rotating frame 3 exceeds a certain value, brake block 19 moves outward and contacts brake disc 2, thereby slowing the blades and preventing damage to the generator caused by excessive current. When the speed decreases, the centrifugal force decreases, causing brake block 19 to move inward, and normal operation resumes. This device has a simple structure, requires no power, operates automatically, and is safe and reliable.

[0081] The entire set of equipment has no direct contact parts except for the bearings and lead-in brushes (except the brake speed limiter), which avoids wear and lubrication, requires almost no maintenance, and greatly reduces investment and operation and maintenance costs.

[0082] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device. This article uses specific examples to illustrate the principles and implementation methods of the technical solution of this patent. The above examples are only used to help understand the method of this patent and its core ideas. The above are only preferred implementation methods of this patent. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this patent, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the patent's concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this patent.
