[0046] Reference below Figure 1-Figure 18 A windmill generator with a rear umbrella-type structure, a spring variable pitch impeller, a coil rotor, and a magnetic steel stator according to an embodiment of the present invention is described, hereinafter referred to as a windmill generator.

[0047] like Figure 1-Figure 18 As shown, the rear umbrella-type spring variable pitch wind impeller coil rotor magnetic steel stator windmill generator includes a combined windmill tower 100, which is fixedly connected to the installation surface, and the top of the combined windmill tower 100 is connected to a generator cabin, and a transmission shaft 230 is rotatably connected in the generator cabin. A coil rotor 330 magnetic steel stator 350 power generation mechanism is also provided in the generator cabin. The coil rotor 330 magnetic steel stator 350 power generation mechanism is connected to the transmission shaft 230 and driven by the transmission shaft 230. The transmission shaft 230 acts as a rotor. A reverse thrust magnetic suspension ring disk mechanism is also provided at the bottom of the generator cabin. The reverse thrust magnetic suspension ring disk mechanism is connected to one end of the transmission shaft 230 to prevent the transmission shaft 230 from rubbing against the bottom of the generator cabin when the transmission shaft 230 is blown by strong wind, thereby affecting the power generation efficiency of the wind turbine generator. The reverse thrust magnetic suspension ring disk mechanism can always maintain a certain distance between the transmission shaft 230 and the generator cabin, thereby eliminating the backward thrust pressure caused by the backward movement of the wind impeller during working rotation, reducing the kinetic energy loss of the bearing rotation friction of the transmission shaft 230, and improving the power generation efficiency.

[0048] The front end of the transmission shaft 230 is also connected to an annular wind impeller mechanism. The annular wind impeller mechanism rotates under the influence of wind, thereby driving the transmission shaft 230 to rotate, and then generates electricity through the coil rotor 330 and the magnetic steel stator 350 generator mechanism. The annular wind impeller mechanism includes a plurality of adaptive windward blades 610. In this embodiment, there are four adaptive windward blades 610. The adaptive windward blades 610 are distributed in a circular ring on the outer ring of the annular wind impeller mechanism, and the inner ring of the annular wind impeller mechanism is hollow. When strong wind blows through the annular wind impeller mechanism, the adaptive windward blades 610 rotate, and part of the wind passes through the inner ring of the annular wind impeller mechanism and blows to a split tail rudder 150 at the tail of the generator cabin to maintain the stability of the engine cabin in strong winds. The split tail rudder 150 is fixedly connected to the tail of the generator cabin to ensure maximum utilization of wind energy and improve the wind resistance of the windmill generator. The diameter of the split tail rudder 150 is equal to the inner diameter of the annular wind impeller mechanism, which can make the wind passing through the inner circle of the annular wind impeller mechanism completely blow onto the split tail rudder 150, so that the split tail rudder 150 can keep the engine compartment stable during the windward process. The split tail rudder 150 adopts a fishtail-like structure, which can increase the stability of the engine compartment itself during wind flow, thereby improving the wind resistance of the wind turbine generator.

[0049] In some embodiments of the present invention, Figure 1 to Figure 4-b As shown, specifically, in order to make the wind turbine generator easier to install, the combined wind turbine tower column 100 includes a main tower 110, the bottom of the main tower 110 is fixedly connected to the installation surface by screws, and the top of the main tower 110 is detachably connected to a sub-tower 120, the main tower 110 and the sub-tower 120 are fixedly connected by screws, and the top of the sub-tower 120 is connected to the generator cabin by a horizontal steering bearing 130, and the generator cabin can achieve horizontal angle adjustment through the horizontal steering bearing 130, and cooperate with the split tail rudder 150, so that the engine cabin can keep facing the wind direction, cope with winds from various directions, and enhance the wind resistance of the wind turbine generator, while the engine cabin and the annular wind impeller mechanism are always facing the windward side, which can keep the annular wind impeller mechanism in the best working state under the current wind force, thereby improving the power generation efficiency of the wind turbine.

[0050] It should be understood that the number of the main tower 110 and the auxiliary tower 120 of the combined windmill tower column 100 is not the only implementation method. In some other embodiments, the installation height of the windmill generator can be increased by connecting multiple auxiliary towers 120 or main towers 110 together according to actual height requirements. The present invention does not elaborate on the number of the main tower 110 and the auxiliary tower 120. It should be understood that the number of the main tower 110 and the auxiliary tower 120 can be flexibly changed without departing from the basic concept of the present invention, and it should be regarded as within the protection scope defined by the present invention.

[0051] like Figure 2 to Figure 4-bAs shown, in order to maintain the wind resistance of the tower column, a support frame is also arranged around the combined wind turbine tower column 100, and the support frame includes a plurality of bottom support bars 141 and a plurality of oblique support bars 142. In this embodiment, the number of the bottom support bars 141 and the oblique support bars 142 are both four, and the four bottom support bars 141 form a square around the periphery of the main tower 110. The support bars are fixedly connected to each other by screws and fixedly connected to the mounting surface; one end of the oblique support bar 142 is fixedly connected to the bottom support bar 141, and the other end is fixedly connected to the connection between the main tower 110 and the auxiliary tower 120, so that the bottom of the combined wind turbine tower column 100 is a stable cone, and the strength of the tower body is enhanced. In order to ensure that the annular wind impeller mechanism on the engine compartment does not touch the oblique support bar 142 when rotating, the length of the auxiliary tower 120 column is greater than the rotation radius of the annular wind impeller mechanism. Through the above arrangement, the annular wind impeller mechanism will not interfere with the oblique support bar 142 during rotation, resulting in damage to the annular wind impeller mechanism. In order to ensure the stability of the support frame, a plurality of bottom connecting bars 143 are connected between the bottom of the main tower 110 and the bottom supporting bar 141 , one end of the bottom connecting bar 143 is connected to the bottom of the main tower 110 , and the other end is connected to the connection between the two bottom supporting bars 141 .

[0052] It should be understood that the bottom support bars 141 are not the only embodiment, and in some other embodiments, triangles or polygons can also be used. The present invention does not elaborate on the shapes formed by the bottom support bars 141. It should be understood that the shapes formed by the bottom support bars 141 can be flexibly changed without departing from the basic concept of the present invention, and should be considered within the protection scope defined by the present invention.

[0053] like Figure 1 , Figure 5 and Figure 6 As shown, the split tail rudder 150 includes a plurality of rudder blades 151, two rudder blades 151 extend horizontally and downwardly on both sides of the split tail rudder 150, and a rudder blade 151 extends upwardly from the top of the split tail rudder 150. Through the rudder blades 151 distributed in a triangular manner, the split tail rudder 150 is entirely covered within the inner circle of the annular wind impeller mechanism, so that the split tail rudder 150 can adjust the windward optimal angle of the wind impeller of the engine through the wind passing through the inner circle. In order to make the connection between the three groups of rudder blades 151 more stable, a consolidation rod 152 is respectively connected between the top rudder blade 151 and the rudder blades 151 on both sides of the bottom to form a stable and consolidated triangular state.

[0054] In some embodiments of the present invention, Figure 1 , Figure 7-Figure 12As shown, specifically, the annular wind impeller mechanism includes a connecting sleeve 630, the inner ring of the connecting sleeve 630 is sleeved with the transmission shaft 230, a connecting sleeve 640 is sleeved with one end of the connecting sleeve 630, the outer ring of the connecting sleeve 630 is connected to the connecting sleeve 640, and the connecting sleeve 640 is connected to a plurality of connecting rods 740. In the present embodiment, the number of the connecting rods 740 corresponds to the number of the adaptive windward blades 610, one end of the connecting rod 740 is connected to the connecting sleeve 640, and the other end extends outward. An annular fixing ring 720 is sleeved with a plurality of connecting rods 740. The connecting rod 740 is centered on a connecting sleeve 640 and is arranged in a ring shape. A plurality of rotating bearings 721 are arranged around the annular fixing ring 720. The number of the rotating bearings 721 corresponds to the number of the connecting rods 740. The rotating bearings 721 are located on one side of the connecting rods 740. The rotating bearings 721 are extended from the ring body of the annular fixing ring 720. After the annular fixing ring 720 is sleeved with the connecting rods 740, the annular fixing ring 720 extends the rotating bearings 721 downward at the sleeved position.

[0055] like Figure 7 As shown, a plurality of support rods 730 are rotatably connected to the rotating bearing 721, a fixed seat 710 is sleeved on one end of the connecting sleeve 630 close to the generator compartment, and a plurality of first bearings 711 are arranged on the periphery of the fixed seat 710. In the present embodiment, the number of the first bearings 711 and the number of the support rods 730 are both four, one end of the support rod 730 is rotatably connected to the first bearing 711, and the other end of the support rod 730 is connected to the rotating bearing 721, so that the support rod 730, the connecting rod 740 and the annular fixing ring 720 are umbrella-shaped.

[0056] like Figure 7As shown, in order to enable the connecting rod 740 to rotate a certain angle, thereby driving the adaptive windward blade 610 to change the angle in the default state, the connecting sleeve 640 includes a plurality of second bearings 641 and an adjusting bearing 642. The second bearings 641 are arranged along the periphery of the connecting sleeve 640, and the connecting rod 740 is connected to the second bearings 641. The number of the second bearings 641 corresponds one-to-one to the connecting rod 740. The inner ring of the adjusting bearing 642 is connected to the outer ring of the connecting sleeve 630, the outer ring of the adjusting bearing 642 is sleeved with a cylindrical body 650, the bottom of the cylindrical body 650 is connected to a first plane volute spring 651, one end of the first plane volute spring 651 is connected to the outer ring of the connecting sleeve 630, and the other end of the first plane volute spring 651 is connected to the inner ring of the cylindrical body 650. When the cylindrical body 650 rotates, the first plane volute spring 651 can be curled, and the first plane volute spring 651 accumulates elastic potential energy. When the external force of the cylindrical body 650 is removed, the elastic potential energy of the first plane volute spring 651 is released, driving the cylindrical body 650 to rotate and reset. A plurality of first bevel teeth 741 are provided at the end of the connecting rod 740 connected to the second bearing 641, and a plurality of second bevel teeth 652 are provided at the top of the cylinder 650, that is, the side close to the connecting rod 740. The first bevel teeth 741 and the second bevel teeth 652 are meshed and connected. By rotating the cylinder 650, the second bevel teeth 652 can drive the first bevel teeth 741 to rotate, thereby rotating the connecting rod 740. The cylinder 650 adjusts the rotation angle of the connecting rod 740 through the second bevel teeth 652.

When the adaptive windward blade 610 is at a default angle, the second plane scroll spring 622 is in a non-compressed state. When the strong wind blows the adaptive windward blade 610, the adaptive windward blade 610 rotates a certain angle, and the second plane scroll spring 622 is in a compressed state at this time; after the strong wind passes, the elastic potential energy of the second plane scroll spring 622 is released, so that the adaptive windward blade 610 is reset. According to the change of wind strength, the adaptive windward blade 610 can rotate to different angles to cope with winds of different strengths and improve the wind resistance of the annular wind impeller mechanism. In order to enable the adaptive windward blade 610 to rotate stably on the connecting rod 740, auxiliary bearings 621 are arranged at the upper and lower edges where the adaptive windward blade 610 is connected to the connecting rod 740. Specifically, an auxiliary bearing 621 is arranged at each of the head and tail ends where the adaptive windward blade 610 is connected to the connecting rod 740. The auxiliary bearing 621 is rotatably connected to the connecting rod 740, so that the adaptive windward blade 610 is connected to three bearings on the connecting rod 740, thereby improving the stability of the adaptive windward blade 610.

[0058] In order to facilitate the adaptive windward blade 610 to adjust the angle of the adaptive windward blade 610 at the annular fixing ring 720, a limiting groove 612 is provided on the adaptive windward blade 610, and the position of the limiting groove 612 coincides with the position of the annular fixing ring 720. The body of the annular fixing ring 720 passes through the limiting groove 612, so that the adaptive windward blade 610 can rotate around the third bearing 620 as the rotation center and around the connecting rod 740 to a certain angle without being blocked by the body of the annular fixing ring 720. The length of the limiting groove 612 can limit the minimum rotation angle of the adaptive windward blade 610. The adaptive windward blade 610 rotates backward under strong wind. The maximum rotation angle is to touch the support rod 730. After being blocked by the support rod 730, it cannot continue to rotate, so as to prevent the adaptive windward blade 610 from being broken by strong wind. The maximum rotation angle is less than 90°. The position of the support rod 730 limits the maximum rotation angle of the adaptive windward blade 610.

[0059] like Fig. 9 , Fig.11 and Fig.12As shown, in order to enable the adaptive windward blade 610 to guide the wind to blow onto the blade surface, one end of the windward surface of the adaptive windward blade 610 is arranged in an arc shape, and the arc is bent toward one side of the windward surface. When the wind blows from the windward surface to the adaptive windward blade 610, the wind can flow along the arc to the blade surface, thereby converting wind energy into mechanical energy and improving the power generation efficiency of the annular wind impeller mechanism. A plurality of reinforcing ribs 611 are arranged on the leeward surface of the adaptive windward blade 610, and the reinforcing ribs 611 are arranged transversely on the leeward surface of the adaptive windward blade 610. The strength and toughness of the adaptive windward blade 610 are improved by the reinforcing ribs 611, and the wind resistance of the adaptive windward blade 610 is improved. In order to facilitate the braking of the annular wind impeller mechanism, a drum brake device (not shown in the drawings) is also arranged on the transmission shaft 230, and the drum brake device can brake the annular wind impeller mechanism to stop working, so as to prevent the annular wind impeller mechanism from being damaged due to excessive wind force.

The magnetic steel stator 350 is fixedly arranged on the inner wall periphery of the generator stator housing 310. The transmission shaft 230 rotates under the drive of the annular wind impeller mechanism, thereby driving the coil rotor 330 and the coil 340 to rotate, cutting the magnetic flux lines and generating current. Since the annular wind impeller mechanism is driven by the wind, it will drive the transmission shaft 230 to move back and forth in the generator cabin. In order to ensure the power generation efficiency of the wind turbine generator, Fig.13 and Fig.14 As shown, the inner wall of the generator compartment is slidably connected to a stator sliding kit 360, the outer periphery of the generator stator housing 310 is arranged in a concave circle, and the stator sliding kit 360 is arranged with a circle of semicircular guide blocks 380 corresponding to the concave circle of the outer part of the generator stator housing 310. The semicircular guide blocks 380 and the concave circle of the outer part of the generator stator housing 310 are mutually engaged, and the stator sliding kit 360 drives the generator stator housing 310 to slide back and forth in the generator compartment.

[0061] like Figure 7 and Fig.13As shown, in order to prevent the stator sliding kit 360 from driving the generator stator housing 310 to slide too far in the generator compartment and exceeding the effective working range of the reverse thrust magnetic suspension ring disk mechanism, a limit sleeve 240 is provided on the inner wall of the generator compartment. The limit sleeve 240 is slidably connected to the stator sliding kit 360. The limit sleeve 240 is used to limit the sliding distance of the stator sliding kit 360 in the generator compartment. The stator sliding kit 360 moves back and forth within the range of the limit sleeve 240, so that the coil rotor 330 magnetic steel stator 350 power generation mechanism maintains a high power generation efficiency.

[0062] like Fig.14 As shown, in order to connect the stator sliding sleeve 360 ​​with the coil rotor 330 and the magnetic steel stator 350 generator mechanism, the stator sliding sleeve 360 ​​includes an upper sliding sleeve 361 and a lower sliding sleeve 362 which are symmetrically arranged. The upper sliding sleeve 361 and the lower sliding sleeve 362 are mutually engaged through buckles to form the housing of the stator sliding sleeve 360, and the semicircular guide blocks 380 are evenly arranged on the inner walls of the upper sliding sleeve 361 and the lower sliding sleeve 362, and the semicircle of the generator stator housing 310 is mutually engaged with the semicircular guide blocks 380.

[0063] In some embodiments of the present invention, Figure 1 , Figure 7 , Figure 15-18 As shown, specifically, the reverse thrust magnetic suspension ring disk mechanism includes a first reverse thrust magnetic suspension ring 410 and a second reverse thrust magnetic suspension ring 420, and the first reverse thrust magnetic suspension ring 410 is fixedly arranged at the bottom of the generator cabin.

[0064] like Fig.18 As shown, in order to facilitate the placement of various components in the generator cabin and provide convenience for subsequent maintenance of the wind turbine, the generator cabin includes a cabin rear cover 220 and a cabin front cover 210, the cabin rear cover 220 is engaged with the cabin front cover 210, a ring frame 221 is provided on the cabin rear cover 220, the first reverse thrust magnetic suspension ring 410 is provided in the ring frame 221, and the coil rotor 330, the magnetic steel stator 350, the power generation mechanism, the stator sliding kit 360 and the generator stator housing 310 are all installed in the cabin front cover 210. The second reverse thrust magnetic suspension ring 420 is rotatably connected to the transmission shaft 230, the first reverse thrust magnetic suspension ring 410 and the second reverse thrust magnetic suspension ring 420 repel each other, and the transmission shaft 230 is spaced a certain distance from the bottom of the generator cabin by the repulsive force.

[0065] The first reverse thrust magnetic suspension ring 410 and the second reverse thrust magnetic suspension ring 420 have the same structure, and both include a plurality of N-pole magnetic rings and a plurality of S-pole magnetic rings arranged at intervals. Specifically, the arrangement order of the N-pole magnetic rings 4 and the S-pole magnetic rings on each group of reverse thrust magnetic suspension rings can be arranged at intervals starting from the S-pole magnetic rings of the inner circle, or can be arranged at intervals starting from the N-pole of the inner circle. The arrangement order of the two groups of reverse thrust magnetic suspension rings must be consistent, that is, the magnetic poles at corresponding positions are of the same sex. The principle of like repels like sex is used to generate a repulsive force between the two groups of reverse thrust magnetic suspension rings to reduce and offset the kinetic energy consumed by the bearing rotation friction caused by the backward thrust pressure of the bearing transmission shaft 230 when working.

[0066] like Figure 15-17 As shown, in order to transport the current generated by the coil rotor 330 magnetic steel stator 350 power generation mechanism to the outside, the reverse thrust magnetic suspension ring disk mechanism also includes a rotating ring telescopic track conductor 500, the rotating ring telescopic track conductor 500 includes a mother conductive track 510 hinged to the generator cabin and a sub conductive track 530 hinged to the end of the transmission shaft 230, and the mother conductive track 510 and the sub conductive track 530 are slidably connected through a conductive rod 570;

[0067] The mother conductive track 510 is hinged to the bottom of the generator cabin through the fifth bearing 520, and the sub-conductive track 530 is hinged to the end of the transmission shaft 230 through the sixth bearing 560. The end faces of the fifth bearing 520 and the sixth bearing 560 are perpendicular to each other. The sixth bearing 560 and the fifth bearing 520 form a universal bearing structure that can swing a certain angle with the transmission shaft 230. When the annular wind impeller mechanism swings due to wind force, the rotating ring telescopic track conductor 500 can work normally.

[0068] like Fig.16 and Fig.17As shown, a plurality of conductive rod grooves 511 are arranged at the inner periphery of the mother conductive track 510, and the conductive rod grooves 511 are arranged in a ring around the conductive rod 570 to prevent the conductive rod 570 from falling out of the mother conductive track 510. A seventh bearing 540 is arranged in the sub-conductive track 530, and the inner ring of the seventh bearing 540 is connected to the conductive rod 570, and the outer ring of the seventh bearing 540 is connected to the inner wall of the sub-conductive track 530. A plurality of groups of conductive discs 550 are also arranged on one side of the seventh bearing 540, and the conductive discs 550 are fixedly connected to the conductive rod 570. The transmission shaft 230 drives the outer shell of the sub-conductive track 530 to rotate, and the current flows through the outer shell through the conductive discs 550 and is transmitted to the conductive rod 570, and then transported to the outside through the mother conductive track 510. In this embodiment, the number of the conductive discs 550 is four groups, and each group of conductive discs 550 is sleeved with the conductive rod 570. A plurality of rotating conductive rings 531 are fixedly arranged inside the inner ring wall of the sub-conductive track 530, and every two rotating conductive rings 531 form a group. The conductive disc 550 is arranged between the two rotating conductive rings 531, and the current is transmitted to the conductive disc 550 through the rotating conductive rings 531. Specifically, the two rotating conductive rings 531 clamp the conductive disc 550, and the two rotating conductive rings 531 rotate and slide in contact with the conductive disc 550 during the rotation of the transmission shaft 230. The rotating conductive rings 531 and the conductive disc 550 always maintain contact, so that the current can flow from the outer shell of the sub-conductive track 530 through the rotating conductive rings 531 into the conductive disc 550, and then be transmitted to the conductive rod 570, thereby completing the current transmission.

[0069] It should be understood that the number of the conductive discs 550 is not the only implementation method, and in some other embodiments, two groups, three groups, five groups, etc. can also be used. The present invention does not elaborate on the number of the conductive discs 550 one by one, and it should be understood that the number of the conductive discs 550 can be flexibly changed without departing from the basic concept of the present invention, and it should be regarded as within the protection scope defined by the present invention.

[0070] The present invention designs the structure of the generator into an oblate shape. Through the above design, the center of the transmission shaft 230 moves a short distance when it rotates one circle, but the outer movement distance of the coil rotor 330 is long, which is more conducive to the movement of the coil rotor 330 and cutting more magnetic field lines, generating more current. The conductive streamlines of the coil rotor 330 pass through the inner ring of the fourth bearing 320 and the transmission shaft 230 near the bottom of the generator compartment, and the current is led to the outside through the rotating ring telescopic track conductor 500. The reverse thrust magnetic suspension ring disk mechanism can generate mutually repelling magnetic suspension forces, reducing the kinetic energy consumed by the uranium bearing rotation friction when the bearing transmission shaft 230 moves.

[0071] The present invention can offset the back-thrust pressure generated by the annular wind impeller mechanism when it is working without contact, and the back-thrust pressure becomes zero, and the rotational friction of the bearing supporting the transmission shaft 230 becomes smaller, thereby realizing movement in an ultra-low friction resistance environment, and finally achieving the purpose of reducing the rotational friction of the bearing supporting the transmission shaft 230, improving work efficiency, and improving the power generation efficiency of the windmill; and according to the size of the windmill power, multiple reverse thrust magnetic levitation rings can be superimposed to meet the magnetic levitation reverse thrust required by the back thrust generated by the operation of the annular wind impeller mechanism.
