Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, specifically a wind turbine generator assembly with a dual-effect vertical axis structure. Background Technology

[0002] With the advancement of the global "dual carbon" goal, the development of renewable energy has become the core of the energy transition. Traditional horizontal axis wind turbines are limited in application in complex urban environments and space-constrained areas due to the need for directional wind orientation and their large size. While existing vertical axis wind turbines have advantages such as strong wind adaptability and low starting wind speed, existing products have problems such as low single-unit power, large energy output fluctuations, and low integration with the scenario. Moreover, they lack effective integration solutions and are difficult to meet diverse energy demands.

[0003] In addition, wind power generation is greatly affected by the weather. At the same time, wind power equipment is exposed to the outdoors for a long time, facing problems such as rainwater erosion, which affects the service life and performance of the equipment.

[0004] Therefore, we propose a wind turbine generator assembly with a dual-effect vertical axis structure to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a wind turbine generator assembly with a dual-effect vertical axis structure to solve the problems mentioned in the background art, such as limited application of traditional horizontal axis wind turbine generators, small single-unit power, large energy output fluctuations, low integration with the scene, and lack of effective integration solutions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wind turbine generator assembly with a dual-effect vertical axis structure, comprising a support column, wherein two sets of the support column are vertically arranged;

[0007] A middle support is provided on the inner side of the middle part of the support column. The two ends of the middle support are fixedly connected to the support column by corner plates and bolts. A lower support is provided on the inner side of the bottom of the support column, and an upper support is provided on the inner side of the top of the support column.

[0008] Wind power generation components are evenly spaced between the lower and middle supports and between the upper and lower supports to generate wind power.

[0009] The disassembly and positioning mechanism is located at the connection points between the lower and upper supports and the pillars to achieve height adjustment.

[0010] A flow guide block is fixedly connected to the top of the support column, and hinge seats are symmetrically installed on the bottom sides of the flow guide block. A photovoltaic panel is fixedly connected to the rotating end of the hinge seat.

[0011] An angle adjustment mechanism is symmetrically arranged at the bottom of the photovoltaic panel to achieve angle adjustment of the photovoltaic panel.

[0012] Preferably, the wind power generation component includes connecting slots equally spaced on both sides of the middle support, the top of the lower support, and the bottom of the upper support. Connecting bearings are movably inserted into the connecting slots. Lower rotating rods are fixedly connected to the inner rings of the connecting bearings at the top of the lower and middle supports. Upper rotating rods are fixedly connected to the inner rings of the connecting bearings at the bottom of the upper and middle supports. Permanent magnet synchronous motors are connected between the corresponding upper and lower rotating rods via couplings.

[0013] Preferably, the wind power generation component further includes S-shaped blades installed at equal angles on the outer ring of the lower and upper swivels. Support frames are fixedly fitted on the outer rings of both ends of the lower and upper swivels. H-shaped blades are installed at equal angles on the outer rings of the support frames. The S-shaped and H-shaped blades on the outer ring of the lower swivel rotate clockwise, and the S-shaped and H-shaped blades on the outer ring of the upper swivel rotate counterclockwise.

[0014] The design of the above structure is equipped with S-shaped blades and H-shaped blades on the lower and upper rotors, respectively, forming a dual-effect vertical shaft structure. The S-shaped blades utilize air resistance to start first and provide initial torque, solving the problem of high starting wind speed in traditional vertical shaft generators. The H-shaped blades, through airfoil design and combined with the counter-rotation of the upper and lower impellers, are conducive to meeting the high-efficiency power generation needs in urban low-wind-speed environments, reducing airflow interference and improving wind energy capture efficiency.

[0015] The rotor is connected to the upper rotating rod via a coupling. Under the action of wind, it rotates clockwise, which in turn drives the rotor to rotate. The stator is connected to the lower rotating rod via a coupling. Under the action of wind, it rotates counterclockwise, which in turn drives the stator to rotate.

[0016] Preferably, the disassembly and positioning mechanism includes movable seats fixedly installed at both ends of the lower support and the upper support. The upper and lower ends of the support column are provided with sliding grooves. The lower support is slidably connected to the bottom sliding groove through the movable seats at both ends, and the upper support is slidably connected to the top sliding groove through the movable seats at both ends.

[0017] Preferably, the disassembly and positioning mechanism further includes a lifting screw rotatably installed inside the movable seat. A knob is fixedly installed at the end of the lifting screw away from the movable seat. A positioning seat is threaded onto the outer ring of the lifting screw, and one end of the positioning seat is fixedly connected to the support column.

[0018] With the above-mentioned structural design, the lower support and the upper support are slidably connected to the support column through the sliding groove of the movable seat. With the help of the lifting screw and knob, the height of the lower support and the upper support can be flexibly adjusted, which is conducive to the convenient disassembly, assembly and maintenance of multiple wind power generation components.

[0019] Preferably, the angle adjustment mechanism includes limiting plates symmetrically installed on the bottom surfaces of both ends of the photovoltaic panel, positioning shaft seats symmetrically installed on both sides of the top of the support column, an adjusting screw fixedly connected to the inner ring of the positioning shaft seat, a turntable fixedly installed at the bottom end of the adjusting screw, a support arm sleeved on the outer ring of the adjusting screw, and the top end of the support arm slidably connected to the corresponding limiting plate.

[0020] The above-mentioned structure design uses a turntable to drive the adjusting screw to rotate, which in turn moves the support arm up and down along the screw, thereby adjusting the tilt angle of the photovoltaic panel. This helps to optimize the orientation of the photovoltaic panel according to the sunlight angle in different seasons, improve the solar energy conversion efficiency, and complement wind power generation, thereby increasing the output of electricity when there is sufficient sunlight.

[0021] Photovoltaic panels, in conjunction with deflector blocks, can prevent rainwater from directly washing over wind turbine components, reducing the risk of corrosion to blades, motors, and other parts, and extending the service life of the equipment.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the wind turbine generator assembly with a dual-effect vertical axis structure;

[0023] 1. The dual-effect vertical axis wind power generation module achieves synergy between low wind speed start-up and high wind speed high-efficiency power generation through the combination of S-shaped and H-shaped blades, significantly improving wind energy capture efficiency. The counter-rotating design of the upper and lower S-shaped and H-shaped blades reduces airflow interference. Combined with the direct-drive permanent magnet motor, it can reduce transmission loss and extend the maintenance cycle. The top photovoltaic panel can optimize the orientation according to the light conditions through the angle adjustment mechanism, improve the solar energy conversion efficiency, and form a multi-energy complementarity with wind power generation, enhancing the stability of energy supply.

[0024] 2. The disassembly and positioning mechanism achieves flexible adjustment of the height of the lower and upper supports through components such as sliding grooves and lifting screws, supporting the rapid installation and precise positioning of wind power generation components. This facilitates convenient disassembly and repair of wind power generation components when damage occurs. In addition, the photovoltaic panels are set at the top of the support pillar as a protective layer, which can block and guide rainwater, thereby reducing the risk of equipment being corroded by rainwater and extending the service life of key components.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6This utility model provides a technical solution: a wind turbine generator assembly with a dual-effect vertical axis structure, including a support column 1, two sets of vertically arranged support columns 1, a middle support 2 arranged on the inner side of the middle part of the support column 1, the two ends of the middle support 2 being bolted to the support column 1 through angle plates 3, a lower support 4 arranged on the inner side of the bottom of the support column 1, and an upper support 5 arranged on the inner side of the top of the support column 1. The wind turbine generator assembly is evenly spaced between the lower support 4 and the middle support 2, and between the upper support 5 and the lower support 4 to achieve wind power generation. The wind turbine generator assembly includes connecting grooves 6 evenly spaced on both sides of the middle support 2, the top of the lower support 4, and the bottom of the upper support 5. Connecting bearings 7 are movably inserted into the connecting grooves 6. The lower support 4... The inner ring of the connecting bearing 7 at the top of the middle support 2 is fixedly connected to the lower rotating rod 8, and the inner ring of the connecting bearing 7 at the bottom of the upper support 5 and the middle support 2 is fixedly connected to the upper rotating rod 10. The upper rotating rod 10 and the lower rotating rod 8 are connected by a coupling to a permanent magnet synchronous motor 9. The wind power generation component also includes S-shaped blades 11 installed at equal angles on the outer ring of the middle part of the lower rotating rod 8 and the upper rotating rod 10. Support frames 12 are fixedly sleeved on the outer rings of both ends of the lower rotating rod 8 and the upper rotating rod 10. H-shaped blades 13 are installed at equal angles on the outer ring of the support frame 12. The S-shaped blades 11 and H-shaped blades 13 on the outer ring of the lower rotating rod 8 rotate clockwise, and the S-shaped blades 11 and H-shaped blades 13 on the outer ring of the upper rotating rod 10 rotate counterclockwise.

[0034] The above structure design achieves efficient power generation across the entire wind speed range through the synergistic effect of S-shaped blades 11 and H-shaped blades 13. In the low wind speed stage, the airflow drives the S-shaped blades 11, which in turn drives the lower rotating rod 8 to rotate clockwise and the upper rotating rod 10 to rotate counterclockwise, thereby driving the rotor and stator of the permanent magnet synchronous motor 9 to rotate and generate initial electrical energy. At this time, the H-shaped blades 13 assist in capturing wind energy due to the low wind speed.

[0035] During medium-to-high wind speeds, when airflow passes over the H-shaped blade 13, the rotation of the H-shaped blade 13 becomes the main driving force. The upper and lower H-shaped blades 13 drive the upper rotating rod 10 and the lower rotating rod 8 to rotate in opposite directions, which can reduce airflow interference. The flexible rotation of the connecting bearing 7 in the connecting groove 6 ensures rotational stability and further improves wind energy conversion efficiency. The cooperation between the support column 1, the middle support 2, the lower support 4, and the upper support 5 can provide stable support for the equally spaced wind power generation components and ensure stability.

[0036] The disassembly and positioning mechanism is set at the connection between the lower support 4 and the upper support 5 and the support column 1 to achieve height adjustment. The disassembly and positioning mechanism includes movable seats 14 fixedly installed at both ends of the lower support 4 and the upper support 5. Slide grooves 15 are opened inside the upper and lower ends of the support column 1. The lower support 4 is slidably connected to the bottom slide groove 15 through the movable seats 14 at both ends. The upper support 5 is slidably connected to the top slide groove 15 through the movable seats 14 at both ends. The disassembly and positioning mechanism also includes a lifting screw 16 rotatably installed inside the movable seat 14. A knob 17 is fixedly installed at the end of the lifting screw 16 away from the movable seat 14. A positioning seat 18 is threaded on the outer ring of the lifting screw 16. One end of the positioning seat 18 is fixedly connected to the support column 1.

[0037] The above-described structure allows the rotating knob 17 to drive the lifting screw 16 to rotate inside the positioning seat 18. Since one end of the positioning seat 18 is fixed to the support column 1 and has a threaded hole matching the lifting screw 16 inside, the lifting screw 16 generates axial displacement when rotating, thereby driving the lower support 4 and the upper support 5 to slide vertically along the slide groove 15 of the support column 1. The slide groove 15 limits the sliding stability of the lower support 4 and the upper support 5, preventing lateral displacement. The lifting screw 16 is fixed in position due to the self-locking characteristic of the thread. After adjusting the lower support 4 and the upper support 5, they can be locked onto the support column 1. When the lower support 4 and the upper support 5 are separated from the wind power generation component, it is convenient to disassemble and repair the wind power generation component. When the lower support 4 and the upper support 5 are connected to the wind power generation component, they can provide stable support for the wind power generation component. The middle support 2 is bolted to the support column 1 through the corner plate 3, further enhancing the stability of the frame.

[0038] A guide block 19 is fixedly connected to the top of the support column 1. Hinges 20 are symmetrically installed on the bottom sides of the guide block 19. A photovoltaic panel 21 is fixedly connected to the rotating end of the hinge 20. An angle adjustment mechanism is symmetrically arranged at the bottom of the photovoltaic panel 21 to realize the angle adjustment of the photovoltaic panel 21. The angle adjustment mechanism includes limiting plates 22 symmetrically installed on the bottom surfaces of both ends of the photovoltaic panel 21. Positioning shaft seats 23 are symmetrically installed on both sides of the top of the support column 1. An adjusting screw 24 is fixedly connected to the inner ring of the positioning shaft seat 23. A turntable 25 is fixedly installed at the bottom end of the adjusting screw 24. A support arm 26 is sleeved on the outer ring of the adjusting screw 24. The top end of the support arm 26 is slidably connected to the corresponding limiting plate 22.

[0039] The above structure is designed so that rotating the turntable 25 drives the adjusting screw 24, which is fixedly connected to the turntable 25, to rotate. The outer ring of the adjusting screw 24 is threaded, forming a threaded engagement with the support arm 26 sleeved on it. Since the positioning shaft seat 23 is fixed to the top of the support column 1 and restricts the axial rotation of the adjusting screw 24, when the adjusting screw 24 rotates, the support arm 26 moves up and down along the axis of the adjusting screw 24 due to the threaded transmission. The top of the support arm 26 is slidably connected to the limiting plate 22 on the bottom surface of the photovoltaic panel 21. When the support arm 26 moves up and down, it pushes the limiting plate 22, thereby driving the photovoltaic panel 21 to rotate around the hinge seat 20, thereby changing the tilt angle of the photovoltaic panel 21. The sliding connection between the support arm 26 and the limiting plate 22 provides horizontal support force. Combined with the fulcrum effect of the hinge seat 20, a stable triangular mechanical structure is formed to ensure that the photovoltaic panel 21 remains fixed in position after strong winds or angle adjustment, avoiding angle deviation due to external forces. The guide block 19 works with the photovoltaic panel 21 to block rainwater erosion and reduce the risk of corrosion of wind power generation components.

[0040] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
