Description

[0002] A wind turbine is an electric device that converts wind energy into mechanical energy, mechanical energy into electrical energy, and finally outputs current energy. It has the characteristics of being clean and environmentally friendly. In a broad sense, wind energy is a type of solar energy, so a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium. The types of wind turbines on the market can be roughly divided into two categories: horizontal axis wind turbines, whose wind rotor's rotation axis is in line with the wind direction; vertical axis wind turbines, whose wind rotor's rotation axis is perpendicular to the ground or the airflow direction. A wind turbine generally includes components such as a wind rotor, a wind rotor shaft, a generator, a rectifier, a tower, a speed limit safety mechanism, and an energy storage device. The wind rotor of a wind turbine rotates under the action of wind force. Through the rotation of the wind rotor, the kinetic energy of the wind is converted into the mechanical energy of the wind rotor. The mechanical energy of the wind rotor drives the wind rotor shaft to rotate, thereby converting the mechanical energy of the wind rotor into the electrical energy of the generator. In the prior art, the windward blades of a horizontal axis wind turbine have poor resistance to strong winds and are easily damaged; the windmill tower column is insufficient to resist strong winds.

[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0047] Reference below Figure 1-Figure 20 The invention describes an umbrella-type tension annular fixed force frame wind impeller reverse thrust magnetic levitation wind turbine generator according to an embodiment of the present invention.

[0048] like Figure 1-Figure 20 As shown, the umbrella-type tension annular fixed force frame wind impeller reverse thrust magnetic levitation wind turbine includes a nacelle 100, a rotor wind impeller 500 rotatably connected to the nacelle 100, and a tower column 600 connected to the nacelle 100. The nacelle 100 includes a rotatably connected rotating shaft 200, and a low-speed tooth 310 is fixedly connected to the shaft of the rotating shaft 200. A generator 320 is arranged in the nacelle 100, and the generator 320 is connected to a gearbox 330. The low-speed tooth 310 is connected to the gearbox 330, and the low-speed tooth 310 rotates synchronously with the rotating shaft 200, thereby driving the generator 320 through the gearbox 330.

[0049] The rotor impeller 500 is rotationally connected to one side of the rotating shaft 200. When the rotor impeller 500 faces the wind, the rotor impeller 500 rotates under the drive of wind energy to generate mechanical energy, which is then converted into electrical energy through the generator 320 to achieve energy conversion. The rotor impeller 500 includes a plurality of groups of blades 510. In the present embodiment, the number of blades 510 is four groups. Each group of blades 510 includes an inner blade 511 and an outer blade 512. The inner blade 511 and the outer blade 512 are connected together by a connecting rod 513. One end of the connecting rod 513 is connected to the rotating shaft 200. The connecting rod 513 extends outward perpendicular to the rotating shaft 200. The inner blade 511 and the outer blade 512 are arranged in sequence along the extension direction of the connecting rod 513. By arranging the blades 510 into a segmented design, it is avoided The rotation of the wind blade rod in the bearing connected by the tension rod annular fixing ring is hindered. In order to further improve the wind resistance of the rotor wind impeller 500, a tension rod 520 is connected to the rotor wind impeller 500 and the rotating shaft 200. One end of the tension rod 520 is connected to the rotor wind impeller 500, and the other end is rotatably connected to the rotating shaft 200. The number of tension rods 520 corresponds to the number of wind blades 510 on the rotor wind impeller 500, that is, each wind blade 510 on the rotor wind impeller 500 is provided with a tension rod 520, and the tension rod 520 is arranged in an umbrella shape around the rotating shaft.

[0050] The nacelle 100 is cylindrical, and a group of anti-thrust magnetic suspension disks 400 are arranged at the bottom of the nacelle 100. A group of anti-thrust magnetic suspension disks 400 are also arranged at one end of the rotating shaft 200 close to the nacelle 100. The two anti-thrust magnetic suspension disks 400 repel each other through magnetic force, and the rotating shaft 200 can slide back and forth in the nacelle 100. When blown by strong wind from the front, the rotating shaft 200 moves toward the inside of the nacelle 100 under the push of the rotor impeller 500. Since the two groups of anti-thrust magnetic suspension disks 400 repel each other, the rotating shaft 200 will never contact the inner wall of the nacelle 100, and the backward thrust pressure on the bearing of the rotating shaft 200 is offset by non-contact in the air, thereby reducing the loss of the rotating working friction of the bearing of the rotating shaft 200 and improving the power generation efficiency.

[0051] The tower column 600 includes a main tower and a sub-tower column 630. The main tower column 610 is rotatably connected to the sub-tower column 630, and the sub-tower column 630 is connected to the nacelle 100 through a universal cross bearing 640. The main tower column 610 is fixedly arranged on the installation foundation surface. A circular track 700 is also arranged around the main tower column 610. A plurality of support tower columns 650 are slidably connected to the circular track 700. Specifically, one end of the support tower column 650 is rotatably connected to the side wall of the sub-tower column 630, and the other end is slidably connected to the circular track 700. The support tower column 650 slides around the circular track 700 and drives the sub-tower column 630 to rotate, that is, the support tower column 650 and the sub-tower column 630 rotate synchronously with the sub-tower column 630 as the center of the circle. In this embodiment, the number of the support tower columns 650 is three, and a stable triangle is formed between the support tower column 650 and the sub-tower column 630, so that the wind resistance of the tower column 600 is higher and can resist stronger winds.

[0052] It should be understood that the number of rotor wind impellers 500, the number of tension rods 520 and the number of support towers 650 are not the only implementation methods. In this embodiment, they are only used as a reference for quantity. In other embodiments, according to actual production requirements, the rotor wind impellers 500 and the tension rods 520 can be five groups, six groups, seven groups, etc., and the support towers 650 can be provided with four, five or even more. As the number of support towers 650 increases, the wind resistance of the towers 600 becomes stronger and stronger. The present invention does not elaborate on the number of rotor wind impeller blades 500, the number of tension rods 520 and the number of support towers 650. It should be understood that without departing from the basic concept of the present invention, the number of rotor wind impeller blades 500, the number of tension rods 520 and the number of support towers 650 can be flexibly changed, which should be regarded as within the protection scope defined by the present invention.

[0053] In some embodiments of the present invention, Figure 1 As shown, specifically, the tail of the nacelle 100 can be detachably connected to a tail rudder 130. For a large wind turbine 320, there is no need to install the tail rudder 130. For a small wind turbine 320, installing the tail rudder 130 can achieve the steering of the wind turbine blade.

[0054] The present invention is divided into Figure 2-Figure 9 The drive unit, Figure 10-Figure 16 The cabin 100 and Figure 17-Figure 20 The tower column 600 is described in three parts.

[0055] In some embodiments of the present invention, Figure 2-Figure 9As shown, specifically, the rotor impeller 500 further includes an annular fixing ring 530, which is sleeved with the connecting rod 513 through a first bearing 531. Specifically, the annular fixing ring 530 is provided with a plurality of first bearings 531, and the number of the first bearings 531 corresponds to the number of the connecting rods 513. The connecting rods 513 pass through the first bearings 531, so that the annular fixing ring 530 is sleeved on the connecting rods 513. The annular fixing ring 530 is located on the connecting rod 513 between the inner blades 511 and the outer blades 512. Figure 4-Figure 6 As shown, the annular fixing ring 530 is also provided with a plurality of second bearings 532, which are arranged above the first bearing 531. The second bearing 532 is used to connect with the tension rod 520, so the end surface of the first bearing 531 and the end surface of the second bearing 532 are perpendicular to each other. One end of the tension rod 520 is hinged to the second bearing 532, and the other end is connected to the rotating shaft 200. The annular fixing ring 530 evenly distributes the force on each tension rod 520, avoiding the situation where the tension of a single tension rod 520 is insufficient and causes the connecting rod 513 to break. Figure 5-Figure 7 As shown, after the annular fixing ring 530 is sleeved on the connecting rod 513, a limiting fixing spring ring 533 is used to fix the position of the annular fixing ring 530 on the connecting rod 513. In this embodiment, each tension rod 520 is correspondingly provided with a tension adjuster 521, and the tension adjuster 521 includes two sleeved nuts, and the two nuts are connected by internal and external threads. By rotating any nut, the distance between the two nuts can be adjusted, thereby changing the length of the tension adjuster 521. The aperture of one end of the two nuts connected to the tension rod 520 is equal to the diameter of the tension rod 520. Specifically, the tension rod 520 is designed to be divided into two sections. A protruding ball is provided at one end of the tension rod 520 connected to the tension adjuster 521. The diameter of the ball is larger than the diameter of the tension rod 520. Two nuts are respectively sleeved in the two tension rods 520, and then the two nuts are threadedly connected to connect the two sections of the tension rod 520 together. Since the diameter of the ball is larger than the diameter of the tension rod 520, that is, the diameter of the ball is larger than the hole diameter of the nut, the tension rod 520 can slide in the tension adjuster 521. By matching and twisting the threads of the two nuts of the tension adjuster 521, the length extension distance of the tension rod 520 is realized, and the tightness is adjusted.

[0056] like Figure 2 , Figure 8 and Fig. 9As shown, one end of the rotating shaft 200 away from the cabin 100 is sleeved with a bearing sleeve 210, and the bearing sleeve 210 is rotatably connected to the rotating shaft 200, and a plurality of third bearings 211 are arranged on the periphery of the bearing sleeve 210, and the number of the third bearings 211 corresponds to the number of the tension rods 520. The two ends of the tension rods 520 are respectively hinged to the third bearings 211 and the second bearings 532, and the tension rods 520, the annular fixing ring 530 and the connecting rod 513 rotate synchronously, and a connecting sleeve 220 is rotatably connected to the rotating shaft 200, and the connecting rod 513 is connected to the rotating shaft 200 through the connecting sleeve 220, and the connecting sleeve 220 is specifically a planetary gear system, and the rotating shaft 200 and the connecting sleeve 220 are connected through a central cylinder 250, and the rotating shaft 200, the central cylinder 250 and the connecting sleeve 220 rotate synchronously, and the rotor impeller 500 rotates and drives the rotating shaft 200 to rotate through the connecting sleeve 220, thereby driving the generator 320 to generate electricity. In this embodiment, the central cylinder 250 extends all the way to the bearing sleeve 210, and can fix the distance between the bearing sleeve 210 and the connecting sleeve 220. When the rotor impeller 500 is working, it plays a role in fixing and maintaining the distance, preventing the bearing sleeve 210 from sliding toward the connecting sleeve 220 and making the tension rod 520 lose its function.

[0057] like Figure 8 and Fig. 9As shown, the connecting sleeve 220 includes a fourth bearing 221 and several fifth bearings 224. The inner ring of the fourth bearing 221 is connected to the outer ring of the central cylinder 250, and the inner ring of the central cylinder 250 is connected to the rotating shaft 200. The outer ring of the fourth bearing 221 is sleeved with a cylindrical body 260. Specifically, the inner ring of the fourth bearing 221 is connected to the outer ring of the central cylinder 250, and the outer ring of the fourth bearing 221 is connected to the inner ring of the cylindrical body 260. The bottom of the inner ring of the cylindrical body 260 is also connected to several transmission teeth 223 driven by a reduction motor. The inner wall of the connecting sleeve 220 is provided with tooth grooves (not shown in the drawings), and the transmission teeth 223 are meshed with the tooth grooves. The reduction motor drives the transmission teeth 223 to rotate along the tooth grooves, thereby driving the outer ring of the fourth bearing 221 and the cylindrical body 260 to rotate synchronously. The fifth bearing 224 is arranged on the periphery of the connecting sleeve 220, and the fifth bearing 224 is used to connect with one end of the connecting rod 513 to fix the position of the connecting rod 513. The end of the connecting rod 513 is provided with a first conical tooth 514, and the first conical tooth 514 faces the inside of the connecting sleeve 220, and the fourth bearing 221 is provided with a second conical tooth 222 on the side close to the first conical tooth 514, and the second conical tooth 222 is arranged on the cylindrical body 260, and the first conical tooth 514 is meshed and connected with the second conical tooth 222. The cylinder 260 is driven by the transmission teeth 223, thereby driving the second conical teeth 222, which can drive the first conical teeth 514 to rotate, thereby driving the connecting rod 513 to rotate a certain angle. The connecting rod 513 is fixedly connected to the fan blade 510. When the connecting rod 513 rotates a certain angle, the fan blade 510 rotates the same angle with the connecting rod 513, realizing the adjustable pitch function of the fan blade 510, and can adjust the fan blade 510 to face the wind according to the direction of the wind, thereby improving the power generation efficiency. The second conical teeth 222 are rotated by the transmission teeth 223 driving the outer ring of the fourth bearing 221 to rotate, and the function of adjusting the blade pitch of the fan blade 510 can be adjusted independently of the rotating shaft 200, because the inner ring of the fourth bearing 221 is sleeved on the outer ring of the center cylinder 220, and the inner ring of the center cylinder 220 is connected to the rotating shaft 200. When the transmission teeth 223 drive the outer ring of the fourth bearing 221 to rotate, the rotating shaft 200 will not rotate. The rotating shaft 200 is driven to rotate by the connecting rod 513 through the connecting sleeve 220. During the rotation of the rotating shaft 200, the first conical teeth 514 are driven by the second conical teeth 222 to adjust the angle of the fan blade 510, so that the rotation efficiency of the rotating shaft 200 is higher, thereby improving the power generation efficiency.

[0058] In some embodiments of the present invention, Figure 10-Figure 16As shown, specifically, the cabin 100 includes an inner cabin 110, and the inner cabin 110 is provided with a plurality of sixth bearings 120. In this embodiment, there are two groups of sixth bearings 120, which are arranged on the rotating shaft 200. The outer ring of the sixth bearing 120 is connected to the inner ring of the universal bearing seat 121, the outer ring of the universal bearing seat 121 is connected to the inner cabin 110, and the rotating shaft 200 is connected to the inner ring of the sixth bearing 120. In order to ensure the concentricity of the rotating shaft 200 during rotation, the sixth bearing 120 adopts a self-aligning ball bearing, which can ensure that the rotating shaft always rotates around the axis during the rotation process to avoid unnecessary shaking. Fig.12 As shown, the inner ring of the sixth bearing 120 is polygonal. In the present embodiment, the inner ring of the sixth bearing 120 is octagonal. The shape of the rotating shaft 200 matches the inner ring of the sixth bearing 120, and the inner ring diameter of the sixth bearing 120 is larger than the diameter of the rotating shaft 200, so that the rotating shaft 200 can drive the inner ring of the sixth bearing 120 to rotate while also moving forward and backward in the horizontal direction. When the rotor impeller blades 500 are subjected to excessive wind force, the force exerted on the rotating shaft 200 will be transmitted to the tower column 600, and the installation point of the tower column 600 is on the ground, forming a long lever arm, so that the wind force exerted on the tower column 600 is increased several times. Under the joint support of several tower columns 650, the tower column 600 increases stability and enhances safety; and the rotating shaft 200 moves back and forth on the inner ring of the sixth bearing 120. When the rotating shaft 200 moves backward, the reverse thrust magnetic suspension disc 400 on the rotating shaft 200 will repel each other with the reverse thrust magnetic suspension disc 400 at the bottom of the cabin 100, and the magnetic force will offset the backward thrust of the rotating shaft 200, so as to reduce the bearing rotation friction caused by the backward thrust, thereby increasing the rotation speed of the rotor impeller 500. The inner cabin 110 is provided with a slot 111 at the position of the low-speed tooth 310. The generator 320 is arranged in the cabin 100 and is located outside the inner cabin 110. The gearbox 330 is arranged at the slot 111. The low-speed tooth 310 is meshed with the high-speed tooth of the gearbox 330. The gearbox 330 is connected to the generator 320, and the gearbox 330 drives the internal high-speed rotation of the generator 320. Specifically, the tooth width of the low-speed tooth 310 is greater than the tooth width of the high-speed tooth, ensuring that the low-speed tooth 310 and the high-speed tooth can always remain meshed during the forward and backward movement of the rotating shaft 200.

[0059] It should be understood that the inner ring of the sixth bearing 120 and the rotating shaft 200 adopting an octagon is not the only embodiment. In some other embodiments, the inner ring of the sixth bearing 120 and the rotating shaft 200 can also adopt a pentagon, hexagon, heptagon, etc. shape according to actual production requirements to ensure that the rotating shaft 200 can still move forward and backward while keeping the rotating shaft 200 rotating after being inserted into the inner ring of the sixth bearing 120. The present invention does not elaborate on the shapes of the inner ring of the sixth bearing 120 and the rotating shaft 200 one by one. It should be understood that, without departing from the basic concept of the present invention, the shapes of the inner ring of the sixth bearing 120 and the rotating shaft 200 can be flexibly changed, which should be regarded as within the protection scope defined by the present invention.

[0060] like Fig.10 , Fig.11 and Fig.13 As shown, in order to prevent the rotating shaft 200 from shifting forward too far and causing the rotating shaft 200 to be separated from the cabin 100, an anti-collision device 230 is also sleeved on the rotating shaft 200 in the cabin 100. The anti-collision device 230 includes an anti-collision bearing 231 and an anti-collision bearing seat 232 arranged in a mirror image. The outer ring of the anti-collision bearing 231 is connected to the anti-collision bearing seat 232, and the inner ring is connected to the rotating shaft 200; the anti-collision bearing seat 232 is connected to the rotating shaft 200 and moves synchronously with the rotating shaft 200. There is a A limit sleeve 233 is provided, which is used to limit the forward and backward movement distance of the two anti-collision bearing seats 232, thereby limiting the forward and backward movement distance of the rotating shaft 200. The distance between the anti-collision bearing seat 232 and the limit sleeve 233 is smaller than the distance between the two anti-thrust magnetic suspension discs 400, so as to avoid excessive wind force, which causes the anti-thrust magnetic suspension disc 400 of the moving rotating shaft 200 to collide too closely with the anti-thrust magnetic suspension disc 400 at the bottom of the cabin 100, and to avoid the two anti-thrust magnetic suspension discs 400 from being worn. Fig.14 As shown, a braking mechanism 240 is also provided on the rotating shaft 200. The braking mechanism 240 is sleeved on the rotating shaft 200 and is used to lock the rotation of the rotating shaft 200. When the wind speed is too high and exceeds the tolerance range of the equipment, the braking mechanism 240 is used to lock the rotor impeller 500 to avoid damage to the equipment, or the braking mechanism 240 is used to lock the equipment when repairing the equipment, so as to perform daily maintenance.

[0061] like Fig.10 As shown, the bottom of the inner cabin 110 is a non-sealed design, and the bottom of the inner cabin 110 is hollowed out to prevent the rotating shaft 200 from touching the bottom of the inner cabin 110 when moving backward; the reverse thrust magnetic suspension disc 400 is arranged at the end of the rotating shaft 200 at the inner cabin 110, and the end of the rotating shaft 200 is located inside the bottom end surface of the inner cabin 110, and another reverse thrust magnetic suspension disc 400 is arranged at the bottom of the cabin 100, and the two reverse thrust magnetic suspension discs 400 repel each other. Fig.16As shown, the reverse thrust magnetic suspension disc 400 includes a plurality of N-pole magnetic rings 410 and a plurality of S-pole magnetic rings 420 arranged at intervals. Specifically, the arrangement order of the N-pole magnetic rings 410 and the S-pole magnetic rings 420 on each set of reverse thrust magnetic suspension discs 400 can be arranged at intervals starting from the S-pole magnetic rings 420 of the inner circle, or can be arranged at intervals starting from the N poles of the inner circle. The arrangement order of the two sets of reverse thrust magnetic suspension discs 400 must be consistent, that is, the magnetic poles at corresponding positions are of the same sex. The principle of like poles repel each other is used to generate a repulsive force between the two sets of reverse thrust magnetic suspension discs 400 to reduce and offset the friction of the rotating bearing caused by the backward thrust pressure of the rotating shaft 200 when working. Fig.15 As shown, the reverse thrust magnetic suspension disc 400 is connected to the bottom of the nacelle 100 via an adjusting screw 430 , and the adjusting screw 430 is used to adjust the safety distance between the two reverse thrust magnetic suspension discs 400 .

[0062] In some embodiments of the present invention, Figure 17-Figure 20 As shown, specifically, the main tower column 610 includes an upper tower column 611 and a lower tower column 612, the upper tower column 611 is connected to the auxiliary tower column 630 through a universal cross bearing 640, and the upper tower column 611 and the lower tower column 612 are connected through the seventh bearing 620, and the lower tower column 612 is fixedly connected to the installation foundation surface, and the upper tower column 611 realizes 360° rotation through the seventh bearing 620, thereby driving the auxiliary tower column 630 and the nacelle 100 to perform synchronous rotation in a large angle range, and the nacelle 100 can realize left and right tilt angle adjustment and front and rear tilt angle adjustment through the universal cross bearing 640 of the auxiliary tower column 630, so that the rotor wind impeller 500 can realize omnidirectional adjustment and face the wind direction in different directions. In order to enhance the wind resistance of the auxiliary tower column 630, the support tower column 650 is hinged with the auxiliary tower column 630 and slides along the circular track 700, thereby assisting the auxiliary tower column 630 in turning.

[0063] like Fig.17 and Fig.19As shown, a buffer device 651 is provided at the bottom of the support tower 650, the top of the buffer device 651 is connected to the support tower 650, and the bottom of the buffer device 651 is rotatably connected to a track shifting mechanism 660. The track shifting mechanism 660 can assist the support tower 650 in sliding on the circular track 700, and the buffer device 651 can buffer the vibration of the auxiliary tower 630 caused by the wind. A spring is provided in the buffer device 651. When the auxiliary tower 630 is subjected to force toward the support tower 650 on the corresponding side, the spring of the buffer device 651 is compressed and the wind force on the corresponding side is offset by elastic potential energy. The limiting mechanisms 661 are mirror-imaged on both sides of the track shifting mechanism 660. The limiting mechanisms 661 are rotatably connected to the track shifting mechanism 660 through an eighth bearing 662.

A groove 701 is provided at the bottom of the circular track 700, and the clamping piece 666 is engaged with the groove 701. When the support tower column 650 moves along the circular track 700, the clamping piece 666 at the bottom of the connecting plate 664 moves along the groove 701, which plays a role in assisting the movement and also prevents the support tower column 650 from deviating from the circular track 700. Fig. 20 As shown, a buffer structure similar to the buffer device 651 is provided at the connection between the connecting plate 664 and the tenth bearing 665 .

[0064] like Fig.19 As shown, in order to enable the supporting tower column 650 to actively slide along the circular track 700, thereby driving the cabin 100 to rotate, a reduction motor 710 is also provided at the bottom of the track shifting mechanism 660, and the circular track 700 is provided with an annular tooth groove (not shown in the accompanying drawings). The output teeth 711 of the reduction motor 710 are meshed and connected with the annular tooth groove. The reduction motor 710 is used to assist the tower column 600 in turning, and can also be used to assist the tower column 600 in fixing its position. When the wind is too strong and blows the cabin 100 in the swinging direction, the reduction motor 710 is used to fix the position of the supporting tower column 650 on the circular track 700.

[0065] It should be understood that the use of spring buffering in the buffer device 651 is not the only embodiment. In some other embodiments, a hydraulic buffering structure can be used to replace the spring buffering according to actual production requirements. The present invention does not elaborate on the structure of the buffer device 651 one by one. It should be understood that the flexible change of the structure of the buffer device 651 without departing from the basic concept of the present invention should be regarded as within the protection scope defined by the present invention.
