[0029] Meanwhile, its impeller has a floating effect, which reduces the pressure on the bottom bearing when it rotates horizontally, thereby improving the durability of the bottom bearing, reducing friction, and increasing its rotational speed. Attached Figure Description

[0052] An annular rotating plate 36 is fixed to the outer side of the bottom of the impeller 30. Multiple active permanent magnet pieces 37 are fixed on the outer wall of the annular rotating plate 36. All active permanent magnet pieces 37 are evenly distributed on the outer wall of the annular rotating plate 36 with the central axis of the annular rotating plate 36 as the center.

[0062] Furthermore, the bottom end of the central sleeve 31 is fixedly connected to the bottom block 32 by bolts, and the top end of the central sleeve 31 is fixedly connected to the top block 33 by bolts. The bottom bearing 34 and the top bearing 35 are both tapered roller bearings. The bottom surface of the bottom block 32 is formed with an upwardly extending lower stepped through hole. The bottom end of the lower stepped through hole is a large-diameter hole segment, and the top end is a small-diameter hole segment. An annular protrusion is formed on the lower outer side wall of the central column 10. The inner ring of the bottom bearing 34 is stuck on the lower outer side wall of the central column 10, and the bottom surface of the inner ring presses against the top surface of the annular protrusion. The outer ring of the bottom bearing 34 is stuck on the inner side wall of the large-diameter hole end of the lower stepped through hole of the bottom block 32, and the top surface of the outer ring presses against the top surface of the large-diameter hole segment of the lower stepped through hole.

The bottom surface of the lower top nut 65 presses against the top surface of the middle block of the top horizontal frame 12.
[0064] The wear-resistant sleeve 61 is a copper sleeve or other wear-resistant sleeve.
[0065] In the above structure, when the impeller 30 is rotated by the wind, the bottom surface of the upper permanent magnet ring 2 and the top surface of the lower permanent magnet ring 1 correspond vertically. Since they are both of the same magnetic pole, they repel each other, thus giving the impeller 30 an upward lifting force and achieving a floating state. This causes the bottom block 32 to be subjected to an upward force, which reduces the pressure of the outer ring of the bottom bearing 34 fixed on it on the corresponding tapered roller, reducing wear difference and thus improving the service life of the bottom bearing 34 and the rotation effect of the impeller 30. Meanwhile, the downward elastic pressure of the buffer spring 62 at the top exerts a downward pressure on the top bearing 35, which can prevent the bottom block 32 from being pushed off the tapered roller of the bottom bearing 34 due to excessive thrust, ensuring stable installation and thus achieving a floating rotation state for the impeller 30.
[0066] Furthermore, multiple horizontal beams extending outward are welded and fixed to the outer side walls of the bottom block 32 and the top block 33. All horizontal beams are evenly distributed on the outer side walls of the bottom block 32 or the top block 33 with the central axis of the bottom block 32 or the top block 33 as the center.

[0080] The generator 50 in this embodiment is a wireless excitation generator, which includes a generator main housing 510. Multiple connecting parts are formed on the upper outer side wall of the generator main housing 510, which are fixedly connected to the bottom surface of the annular plate 111 by bolts.
[0081] A bottom cover 513 is fixed to the bottom of the generator main housing 510. An annular protrusion is formed on the inner side of the top surface of the side plate of the bottom cover 513, and an inner annular groove is formed on the inner side wall of the bottom end of the side plate of the generator main housing 510. The annular protrusion is inserted into the inner annular groove and the two cooperate.

The extensions and the corresponding outer extensions are vertically aligned and fixedly connected by bolts.
[0082] A stator assembly 511 (including a stator and coil windings wound on the stator) is fixed in the middle of the inner wall of the generator main housing 510. A rotating shaft 512 is inserted into the generator main housing 510. The upper part of the rotating shaft 512 is movably connected to the top plate of the generator main housing 510 through a bearing. Its top end extends out of the top end of the middle through hole of the top plate of the generator main housing 510. The bottom end of the rotating shaft 512 is movably connected to the bottom cover 513 through a bearing. A rotor assembly 515 (including a rotor core of multiple stacked silicon steel sheets and coil windings wound on it) is fixed on the outer side of the middle part of the rotating shaft 512. The rotor assembly 515 is inserted into the middle through hole of the stator assembly 511. There is a gap between the outer side of the rotor assembly 515 and the inner side of the middle through hole of the stator assembly 511, and the two cooperate with each other.
[0083] The top of the rotating shaft 512 is fixed with a rotating wheel 516, which is an aluminum alloy wheel. A connecting seat 517 (which is a pure iron seat) is inserted on the outer side wall of the rotating wheel 516. Multiple axially extending magnet pieces 518 (which are permanent magnet pieces) are fixed on the outer side wall of the connecting seat 517. Multiple heat dissipation and weight reduction grooves are formed on the bottom end face of the rotating wheel 516.
[0084] The top surface of the rotating shaft 512 has an extension formed in the middle. The rotating wheel 516 is inserted into the extension, and the bottom surface of the rotating wheel 516 presses against the top surface of the rotating shaft 512. The rotating wheel 516 is connected to the extension by a key. A locking nut is screwed to the top of the extension, and the bottom surface of the locking nut presses against the top surface of the middle part of the rotating wheel 516. An annular groove is formed on the upper outer wall of the rotating wheel 516, and a connecting seat 517 is inserted into the annular groove. The connecting seat 517 is an annular body, and multiple vertical slots are formed on its inner sidewall. Correspondingly, multiple inner vertical slots are formed on the inner sidewall of the annular groove. The top of the inner vertical slots extends out of the top surface of the rotating wheel 516. Each locking strip is inserted into the corresponding vertical slot and inner vertical slot to fix the connecting seat 517 and the rotating wheel 516. Multiple vertically extending mounting grooves are formed on the outer wall of the connecting seat 517. The inner width of the mounting groove is greater than the outer width. The magnet pieces 518 are inserted into the corresponding mounting grooves and fixed by adhesive. All magnet pieces 518 are evenly distributed on the connecting seat 517 with the central axis of the connecting seat 517 as the center. In every two adjacent magnet pieces 518, the outer side of one magnet piece 518 is the south pole and the inner side is the north pole, and the inner side of the other magnet piece 518 is the south pole and the outer side is the north pole. All magnet pieces 518 are arranged in this manner.
[0085] Furthermore, a heat dissipation impeller 519 is fixed on the upper part of the rotating shaft 512, and the heat dissipation impeller 519 is located between the bottom surface of the top plate of the generator main housing 510 and the top surface of the rotor assembly 515.
[0086] The top plate of the generator main housing 510 has multiple upper ventilation holes formed on its edge, and the bottom plate of the bottom cover 513 has multiple lower ventilation holes formed on its edge.
[0087] Furthermore, a lower wireless charging circuit board 104 is fixed in the middle of the top surface of the bottom plate of the bottom cover 513, and a lower wireless induction coil 105 is fixed on the lower wireless charging circuit board 104. The lower wireless induction coil 105 is electrically connected to the lower wireless charging circuit board 104, and the lower part of the rotating shaft 512 is inserted into the middle through hole of the lower wireless charging circuit board 104 and the lower wireless induction coil 105.
[0088] An upper wireless charging circuit board 106 is fixed on the outer wall of the lower part of the rotating shaft 512. An upper wireless induction coil 107 is fixed on the upper wireless charging circuit board 106. The upper wireless induction coil 107 is located directly above the lower wireless induction coil 105 and the two are close to each other. The upper wireless charging circuit board 106 is electrically connected to the coil winding of the rotor assembly 515.
[0089] A controller 108 is fixed on the outer side of the generator main housing 510. The coil windings of the lower wireless charging circuit board 104 and the stator assembly 511 are electrically connected to the control motherboard inside the controller 108. One end of the input wire and the output wire are electrically connected to the control motherboard, and the other end extends out of the controller 108.
[0090] The input and output wires of the controller 108 extend out of one end of the controller 108 and are electrically connected to the control circuit board inside the control box 70. The electric cylinder 17 is electrically connected to the control circuit board inside the control box 70 through an electrical connection wire. The control circuit board of the control box 70 is electrically connected to the main output wire, which extends downward along the bottom horizontal grid frame 11 and the lower support column 20 and extends into the factory building below the lower support column 20 (the lower support column 20 is fixed on the factory roof), and is electrically connected to the control host inside. The control host is a conventional structure and will not be described in detail here.
[0091] In this embodiment, when in use, the push rods of all electric cylinders 17 can be used to push the annular sliding sleeve 16 to slide along the annular guide rail 113, thereby causing all push rods 162 to swing, thus opening all damper plates 15 at the same angle and opening the same flow channel. It can adjust the damper plates 15 to any certain angle to control the air intake.
[0092] After the air enters the interior, it will drive the impeller 30 to rotate. Since the opening tilt direction of its damper plate 15 is only one direction, the air it brings in can only rotate the impeller 30 in one direction, such as clockwise or counterclockwise. In this embodiment, according to the attached figure, it rotates counterclockwise. When rotating, the swing rod 322 moves counterclockwise along the inclined wall of the tooth of the annular tooth 38, producing a clicking sound when it collides with the tooth. In this structure, when the impeller 30 rotates in the opposite direction, its swing rod 322 will hit the vertical wall at the high end of one of the teeth, thereby preventing the impeller 30 from rotating in the opposite direction and achieving a locking effect.
[0093] After the impeller 30 rotates, the annular rotating plate 36 rotates, causing all the active permanent magnet pieces 37 to rotate. The magnet pieces 518 of all the generators 50 approach and cooperate with the active permanent magnet pieces 37 of the annular rotating plate 36. Their like poles repel each other and their unlike poles attract each other, which drives the connecting seat 517 to rotate, causing the rotating shaft 512 to rotate, and causing the rotor assembly 515 to rotate.
[0094] At this time, it would not generate electricity.
[0095] A sensing element is fixed to the bottom surface of one of the lower transverse beams of the impeller 30, and a proximity switch is fixed to the top surface of the corresponding bottom horizontal grid frame 11. The sensing end of the proximity switch corresponds to the sensing element (the proximity switch is electrically connected to the control circuit board of the control box 70 via an electrical connection wire). By sensing the sensing element through the proximity switch, the number of revolutions of the impeller 30 per unit time can be obtained, thereby understanding its operation and conveying. When the speed of the impeller 30 reaches a certain level, such as when the outer diameter of the impeller 30 reaches 5 meters, it only needs to reach a speed of 10 revolutions per minute. At this time, the controller electrically connected to the control circuit board of the control box 70 operates, causing the corresponding storage battery 80 to supply power to the lower wireless charging circuit board 104 of the corresponding generator 50 (the lower wireless charging circuit is powered by the input wire of the controller 108). Power is supplied to board 104. The current is sent to controller 108, where it is adjusted by a rectifier (in this embodiment, the rectifier is an adjustable current rectifier, such as a silicon controlled rectifier) connected to the control board. The current can be adjusted according to the speed of impeller 30 to ensure the best power generation under the wind conditions. The current is then sent to the lower wireless induction coil 105 on the lower wireless charging board 104, so that the lower wireless induction coil 105 generates an induced magnetic field, which cuts the upper wireless induction coil 107, causing the upper wireless induction coil 107 to generate an induced electromotive force and current. This current is alternating current. After being rectified by the rectifier circuit on the upper wireless charging board 106, it becomes direct current and is sent to the coil winding of rotor assembly 15 to generate an induced magnetic field.
[0096] As the shaft 512 rotates, the induced magnetic field of the coil winding of the rotor assembly 15 cuts the stator assembly 11, thereby generating an induced current in the coil winding of the stator assembly 11. The induced current is transmitted to the control main board of the controller 108 and output to the control circuit board of the electrical control box 70 through the output wire. The AC power is converted into DC power by the three-phase bridge rectifier or other type of rectifier on the control circuit board. Part of the DC power enters the storage battery 80 to charge it, and most of the remaining current enters the storage battery in the factory for storage.
[0097] When all damper plates 15 are closed, there is a flow gap 19 between each two adjacent damper plates 15, which can ensure that a small amount of air can still enter the interior. This structure allows some air to enter even when all damper plates 15 are closed in strong winds, ensuring airflow and preventing the embodiment from being blown over or damaged by the wind due to excessive wind resistance.
[0098] The current is supplied to the controller 108, where it is adjusted by a rectifier (in this embodiment, the rectifier is an adjustable current rectifier, such as a silicon controlled rectifier) connected to the control motherboard. The current is then supplied to the lower wireless induction coil 105 on the lower wireless charging circuit board 104, thereby causing the lower wireless induction coil 105 to generate an induced magnetic field. When the airflow is low and the impeller 30 does not need to rotate, the rectifier in the control motherboard can be adjusted to increase the induced magnetic field generated by the lower wireless induction coil 105. At this time, the shaft 512 requires more force to rotate. When the airflow is low, the impeller 30 rotates slowly, and the force required to rotate it is small. Therefore, the shaft 512 is not easy to rotate. When the shaft 512 does not rotate, the magnet 518 of the generator 50 does not rotate, which in turn restricts the active permanent magnet 37 from rotating, thus preventing the annular rotating plate 36 from rotating. In other words, the impeller 30 cannot rotate, achieving a locking and stopping of rotation.
[0099] The proximity switch senses that the impeller 30 is rotating too fast. If the outer diameter of the impeller 30 reaches 5 meters, it only needs to rotate more than 100 times per minute to control the push rods of all electric cylinders 17 to retract, so that the annular sliding sleeve 16 slides along the annular guide rail 113, thereby closing all damper plates 15 and preventing the impeller 30 from rotating too fast, thus providing a protective effect.
[0100] Since all components in this embodiment are outdoors, their surfaces can be coated with waterproof and rust-proof paint or other rust-proof measures. The electric cylinder 17 can be selected with a waterproof rating of IP66 or higher (including IP66), and the generator 50 can also be selected with a waterproof rating of IP66 or higher (including IP66).
[0101] Meanwhile, the stator assembly 511 has a socket formed on the bottom surface of the stator. The sensing end of the temperature sensor 9 is inserted into the socket and fixed (it can be fixed by adhesive or other means, which will not be described in detail here). Its outer side wall is close to the inner side wall of the socket. The electrical connection line of the temperature sensor 9 extends out of the generator main housing 510. The temperature sensor 9 is electrically connected to the control board of the controller 108 through the electrical connection line. It can transmit the sensed temperature signal to the control board. The control board can monitor the temperature and reduce the current entering the lower wireless induction coil 105 on the lower wireless charging circuit board 104 when the temperature is too high, thereby reducing the excitation voltage and lowering the temperature inside the generator main housing 510, but it can still maintain the power generation state to ensure continuous power generation.
[0102] In this embodiment, the generator 50 can also be a brushless generator. Among the multiple electrical output connection lines on the bottom control board, at least one is an input wire, which is electrically connected to the corresponding storage battery 80 to deliver current to the bottom control board. The current is adjusted by a rectifier (in this embodiment, the rectifier is an adjustable current rectifier, such as a silicon controlled rectifier) electrically connected to the bottom control board, and the current is delivered to the excitation winding of the brushless generator to generate an induced magnetic field, thereby realizing power generation. Since the brushless generator can adopt existing conventional structures, it will not be described in detail here.
[0103] At the same time, such as Figure 17 As shown, a side connecting edge 500 is formed or welded to one side wall of the middle block of the bottom horizontal grid frame 11. A through hole is formed on the side connecting edge 500. An extension edge 600 is formed on the outer side wall of the bottom block 32 of the impeller 30. The screw part of the positioning bolt 601 is inserted into the through hole and screwed into the corresponding screwed through hole of the extension edge 600. With this structure, the impeller 30 is fixed to the bottom horizontal grid frame 11 during maintenance, so that the impeller 30 cannot rotate, thus facilitating maintenance.
[0104] And such Figure 18 , 19 As shown, a perovskite solar thin-film battery 700 (which is a commercially available product and will not be described in detail here) is fixed on the outer wall of the damper plate 15. Its electrical connector extends out of the inner wall of the damper plate 15 and is electrically connected to the electrical control box 70 via an electrical connection cable or directly connected to the corresponding control box in the factory. The control box then transmits electrical energy to the battery for storage.
[0105] Finally, the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
