The utility model supports and installs multiple groups of combined power generation mechanisms through a multi-layer tower frame, improves the overall stability of the power generation device, and through the cooperation of different combined power generation mechanisms, increases the wind cut surface, improves the power generation efficiency, and realizes multi-directional power generation; however, this utility model patent still has the following defects:

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figures 1 - 9As shown in the figure, a assembled bidirectional rotating wind power tower includes a support tower base 1 and a multi-layer tower frame 2. The multi-layer tower frame 2 is composed of an odd number (at least 3) of tower sub-units spliced up and down. Starting from the support tower base 1 upwards, every two adjacent tower sub-units form a tower frame unit group. A first power generation mechanism 3 is arranged in the tower frame unit group. A second power generation mechanism 4 is arranged on the tower sub-unit at the top of the multi-layer tower frame 2. The first power generation mechanism 3 includes an upper main shaft 301 and a lower main shaft 302 respectively arranged in the upper and lower adjacent tower sub-units in the same tower frame unit group, a first upper combined blade 303 fixed on the upper main shaft 301, a first lower combined blade 304 fixed on the lower main shaft 302, and a bidirectional rotating generator set. The rotating directions of the first upper combined blade 303 and the first lower combined blade 304 are opposite under the blowing of wind. Among them, starting from the support tower base 1 upwards, every two adjacent tower sub-units forming a tower frame unit group means that taking the number of tower sub-units as 7 as an example, starting from the support tower base 1 upwards, there are a first tower sub-unit, a second tower sub-unit, a third tower sub-unit, a fourth tower sub-unit, a fifth tower sub-unit, a sixth tower sub-unit, and a seventh tower sub-unit respectively. Starting from the support tower base 1 upwards in sequence, the first tower sub-unit and the second tower sub-unit form the first tower frame unit group, the third tower sub-unit and the fourth tower sub-unit form the second tower frame unit group, the fifth tower sub-unit and the sixth tower sub-unit form the second tower frame unit group, and the second power generation mechanism is arranged on the seventh tower sub-unit.

[0049] The bidirectional rotating generator set includes a first driving gear 305 fixed on the upper main shaft 301, a second driving gear 307 fixed on the lower main shaft 302, and at least one vertical axis bidirectional rotating generator 306 fixed on the multi-layer tower frame 2. A first driven gear 3063 and a second driven gear 3064 respectively meshing with the first driving gear 305 and the second driving gear 307 are fixed on the inner rotor central axis 3061 and the outer rotor lower end cover axis 3062 of the vertical axis bidirectional rotating generator 306 respectively. Under the action of wind, during the opposite-direction rotation process of the first upper combined blade 303 and the first lower combined blade 304, the first driving gear 305 and the second driving gear 307 are driven to perform coaxial opposite-direction synchronous rotation, and then the first driven gear 3063 and the second driven gear 3064 are respectively driven to perform opposite-direction rotation, and then the inner rotor central axis 3061 and the outer rotor lower end cover axis 3062 are driven to perform coaxial opposite-direction rotation, and then the inner rotor and the outer rotor are driven to perform coaxial opposite-direction rotation, effectively improving the power generation efficiency of the bidirectional rotating generator set.

[0050] At the upper ends of the upper main shaft 301 and the lower main shaft 302, there are upper fixing seats 5 of the main shaft fixed on the multi-layer tower 2. The upper ends of the upper main shaft 301 and the lower main shaft 302 are rotatably installed in the upper fixing seats 5 of the main shaft through first ball bearings 6. The first ball bearings 6 can reduce the frictional force between the upper main shaft 301 and the lower main shaft 302 and the corresponding upper fixing seats 5 of the main shaft, and can ensure the smooth rotation of the upper main shaft 301 and the lower main shaft 302 under the action of wind force.

[0051] At the upper ends of the upper main shaft 301 and the lower main shaft 302, there are brake assemblies 11 located below the upper fixing seats 5 of the main shaft. By setting the brake assemblies, the upper main shaft 301 and the lower main shaft 302 can be braked. When the power generation of the bidirectional rotation generator set meets the requirements, the upper main shaft 301 and the lower main shaft 302 can be braked through the brake assemblies 11 to stop the rotation of the upper main shaft 301 and the lower main shaft 302. Also, according to the wind volume situation, the upper main shaft 301 and the lower main shaft 302 can be braked through the brake assemblies to decelerate the operation of the upper main shaft 301 and the lower main shaft 302.

[0052] At the lower ends of the upper main shaft 301 and the lower main shaft 302, there are lower fixing seats 7 of the main shaft fixed on the multi-layer tower 2. The lower ends of the upper main shaft 301 and the lower main shaft 302 are rotatably installed in the lower fixing seats 7 of the main shaft through second ball bearings 8. Below the second ball bearings 8, there are first thrust bearings 9. Between the inner ring of the second ball bearings 8 and the upper ring of the first thrust bearings 9, there are first washers 21. The second ball bearings 8 can reduce the frictional force between the lower ends of the upper main shaft 301 and the lower main shaft 302 and the corresponding lower fixing seats 7 of the main shaft, thereby ensuring the smooth rotation of the upper main shaft 301 and the lower main shaft 302 under the action of wind force. The setting of the first thrust bearings 9 can provide good longitudinal support for the upper main shaft 301 and the lower main shaft 302, and avoid the influence of the frictional force between the upper main shaft 301 and the lower main shaft 302 and the bottom walls of the corresponding lower fixing seats 7 of the main shaft on the rotation of the upper main shaft 301 and the lower main shaft 302.

[0053] At the lower ends of the upper main shaft 301 and the lower main shaft 302, there are magnetic levitation assemblies 10 located above the lower fixing seats 7 of the main shaft. The magnetic levitation assemblies 10 are connected to the lower fixing seats 7 of the main shaft through support cylinders 20. By setting the magnetic levitation assemblies, the gravity of the upper main shaft 301 and the lower main shaft 302 and their respective first upper combined blades 303 and first lower combined blades 304 can be dispersed to the multi-layer tower 2, effectively reducing the force on the lower ends of the upper main shaft 301 and the lower main shaft 302.

The upper part of the top main shaft 401 is fixed on the inner rotor of the second two-way rotating generator 404. The second lower combined blade 403 is fixed on the top main shaft 401. The top main shaft 401 is rotatably installed on the topmost tower sub-unit. The second upper combined blade 402 and the second lower combined blade 403 rotate in opposite directions under the action of wind force, thereby driving the inner and outer rotors of the second two-way rotating generator 404 to rotate in opposite directions.

[0055] Specifically, as Figures 6 - 8 shown, the second two-way rotating generator 404 is installed on the composite slewing bearing 12. The lower end of the composite slewing bearing 12 is fixed on the multi-layer tower 2. The upper end of the top main shaft 401 is fixed on the composite slewing bearing 12 to be fixedly connected with the inner rotor of the second two-way rotating generator 404 through the composite slewing bearing 12.

[0056] The composite slewing bearing 12 includes an outer cylinder seat 1201 and an inner cylinder seat 1202 fixed on the multi-layer tower 2.

A cylindrical shell is provided at the outer edge of the motor upper cover 4042 and the motor lower cover 4043, and the motor upper cover 4042 and the motor lower cover 4043 are respectively fixed to the upper and lower ends of the cylindrical shell by bolts.

[0059] The upper motor cover 4042 and the lower motor cover 4043 are respectively rotatably connected to the inner motor housing 4041 through the third ball bearings 13, and after the upper motor cover 4042 and the lower motor cover 4043 are fixedly connected, they form the outer rotor of the second power generation mechanism 4 together with the inner magnets on their inner side surfaces. The inner motor housing 4041 and the windings thereon form the inner rotor of the second power generation mechanism 4; a jacket ring 14 is fixedly provided on the lower side surface of the lower motor cover 4043. Specifically, the jacket ring 14 is integrally formed on the lower side surface of the lower motor cover 4043; the inner side wall of the jacket ring 14 is rotatably connected to the outer cylinder base 1201 through the fourth ball bearing 15, and the outer cylinder base 1201 is rotatably connected to the inner cylinder base 1202 through the fifth ball bearing 16, so as to ensure the smooth rotation of the inner cylinder base 1202 and the jacket ring 14 relative to the outer cylinder base 1201 through the fourth ball bearing 15 and the fifth ball bearing 16; an outer support base 17 is provided on the outer periphery of the outer cylinder base 1201, a second thrust bearing 18 is provided on the outer support base 17, and a second washer 19 is provided between the outer ring of the fourth ball bearing 15 and the upper ring of the second thrust bearing 18. The second thrust bearing 18 can bear the gravity of the second two-way rotary generator 404 and ensure the smooth rotation of the outer rotor of the second two-way rotary generator 404.

[0060] As Figure 7 shown, a spindle upper fixing seat 5 fixed on the multi-layer tower 2 is provided at the upper end of the top spindle 401, and the top spindle 401 is rotatably installed in the spindle upper fixing seat 5 through the first ball bearing 6;

[0064] As Figure 4 and Figure 7As shown, the brake assembly 11 includes a brake support frame 1101, a brake caliper 1102, and a brake disc 1103.

The magnetic pole polarities of the upper magnetic steel 1003 and the lower magnetic steel 1004 are the same. According to the principle of like poles repelling each other, the upper support disc 1001 and the lower support disc 1002 are always kept at a stable specific distance, thereby providing radial support for the upper main shaft 301, the lower main shaft 302, or the top main shaft 401. During operation, the gravity of the upper main shaft 301, the lower main shaft 302, or the top main shaft 401 and the combined blades on them is first dispersed to the upper support disc 1001, and then through the cooperation of the upper magnetic steel 1003 and the lower magnetic steel 1004, the gravity is dispersed to the lower support disc 1002, and the lower support disc 1002 then disperses it to the multi-layer tower 2 through the support cylinder 20.

[0066] As Figure 5 and Figure 9 shown, the vertical axis two-way rotation generator 306 includes a housing 30611, an outer rotor assembly and an inner rotor assembly arranged in the housing 30611. The housing 30611 is fixed on the multi-layer tower 2. The inner rotor assembly includes an inner rotor central shaft 3061. The outer rotor assembly includes an outer rotor lower end cover shaft 3062. The inner rotor central shaft 3061 and the outer rotor lower end cover shaft 3062 drive the inner rotor assembly and the outer rotor assembly to rotate in opposite directions respectively under the drive of the first upper combined blade 303 and the first lower combined blade 304.

[0067] The inner rotor assembly further includes a central magnet 30612 fixed on the central axis 3061 of the inner rotor and a winding sleeve 3065 fixed on the upper end of the lower end cover shaft 3062 of the outer rotor. A winding is fixed on the inner side wall of the winding sleeve 3065. The upper end of the winding sleeve 3065 is fixed with an upper end cover 3066 of the outer rotor. The upper and lower ends of the housing 30611 are respectively fixed with an upper end cover 3067 and a lower end cover 3068 of the housing. The central axis 3061 of the inner rotor is rotatably connected to the upper end cover 3067 of the housing, the upper end cover 3066 of the outer rotor and the lower end cover shaft 3062 of the outer rotor through a sixth ball bearing 3069. The lower end cover shaft 3062 of the outer rotor is rotatably connected to the lower end cover 3068 of the housing through a seventh ball bearing 30610;

[0068] During the process of the central axis 3061 of the inner rotor and the lower end cover shaft 3062 of the outer rotor rotating in opposite directions, they respectively drive the central magnet 30612 and the winding sleeve 3065 to rotate in opposite directions with the same axis, thereby achieving double power generation efficiency.

[0069] As Figure 1 、 Figure 2 and Figure 6 shown, both the first upper combined blade 303 and the first lower combined blade 304 include a first wind-tunnel type wind blade 3031 and a vertical wind blade 3032. The vertical wind blade 3032 is of a vertical plate type or an arc-shaped structure. The second upper combined blade 402 includes a lantern-shaped fan blade fixed on the outer rotor of the second bidirectional rotary generator 404. The second lower combined blade 403 includes a second wind-tunnel type wind blade 4031 and an outer wind blade 4032. The outer wind blade 4032 has a cross-section of a vertical plate type or an arc-shaped structure. The first upper combined blade 303 and the first lower combined blade 304 also both include a horizontal wind blade 3033;

[0070] That is, the first upper combined blade 303 is in the form of a combination of a first air duct type wind blade 3031 and a vertical blade 3032 of a vertical plate type, or in the form of a combination of a first air duct type wind blade 3031 and a vertical blade 3032 with an arc-shaped structure; the first lower combined blade 304 is in the form of a combination of a first air duct type wind blade 3031 and a vertical blade 3032 of a vertical plate type, or in the form of a combination of a first air duct type wind blade 3031 and a vertical blade 3032 with an arc-shaped structure; it is also possible to add a cross wind blade 3033 on the basis of the forms of the foregoing first upper combined blade 303 and first lower combined blade 304, so as to improve the wind blocking ability of the first upper combined blade 303 and the first lower combined blade 304 and effectively utilize wind energy; the second lower combined blade 403 is in the form of a combination of a second air duct type wind blade 4031 and an outer wind blade 4032 with an arc-shaped cross section, or in the form of a combination of a second air duct type wind blade 4031 and an outer wind blade 4032 of a vertical plate type; thus, in specific implementation, the combination forms of the first upper combined blade 303, the first lower combined blade 304, and the second lower combined blade 403 can be flexibly adjusted according to needs.

[0071] As Figure 1 and Figure 6 shown, a lightning rod 22 is provided at the top of the second upper combined blade 402, and a lightning arrester 23 is provided on the lightning rod 22; the setting of the lightning arrester 23 plays a good lightning protection role for the assembled two-way rotating wind power tower.

[0072] When the assembled bidirectional rotating wind power tower provided by the present utility model is specifically implemented, the support tower base 1 is fixed on the concrete foundation made at the installation position through bolts. According to the requirement of power generation capacity, the required number of tower sub-units (an odd number of tower sub-units) is successively fixed and erected on the support tower base 1. A corresponding first power generation mechanism 3 is arranged in each tower sub-unit, and a second power generation mechanism 4 is fixed at the top of the topmost tower sub-unit. Then, the carbon brush assembly in the slip ring assembly connected to the first power generation mechanism 3 and the second power generation mechanism 4 is connected to the electric energy storage device through a wire (all the carbon brush assemblies can be connected to the same electric energy storage device through a wire, or each carbon brush assembly can be connected to a corresponding electric energy storage device through a wire, or each electric energy storage device is connected to multiple carbon brush assemblies); in the daily working state, under the action of wind, the first upper combined blade 303 and the first lower combined blade 304 of the first power generation mechanism 3 drive the upper main shaft 301 and the lower main shaft 302 to drive the first driving gear 305 and the second driving gear 307 to rotate in opposite directions respectively. The first driving gear 305 and the second driving gear 307 respectively drive a plurality of first driven gears 3063 and second driven gears 3064 meshed with them to rotate in opposite directions, thereby driving the outer rotor and the inner rotor of the vertical axis bidirectional rotating generator 306 to rotate in opposite directions. The slip ring assembly corresponding to the vertical axis bidirectional rotating generator 306 collects the electric energy generated by the vertical axis bidirectional rotating generator 306; the second upper combined blade 402 and the second lower combined blade 403 of the second power generation mechanism 4 drive the outer rotor and the inner rotor of the second power generation mechanism 4 to rotate in opposite directions. The slip ring assembly corresponding to the second power generation mechanism 4 collects the electric energy generated by the second power generation mechanism 4; finally, all the generated electric energy is transmitted to the electric energy storage device for storage; since the inner and outer rotors of the first power generation mechanism 3 and the second power generation mechanism 4 in the present utility model rotate in opposite directions, compared with the traditional generator in which only one of the stator and the rotor rotates, the output power is increased by more than twice; and due to the setting of the first thrust bearing 9 and the second thrust bearing 18, and the magnetic levitation assembly 10 can effectively disperse the gravity of the first power generation mechanism 3 and the second power generation mechanism 4, effectively ensuring the stability of the operation of the first power generation mechanism 3 and the second power generation mechanism 4, thereby further increasing the output power of the first power generation mechanism 3 and the second power generation mechanism 4. Compared with the traditional generator in which only one of the stator and the rotor rotates, the output power can be increased by more than three times.

[0073] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
