Description

Technical Field

[0001] This invention relates to the field of micro-wind power generation technology, specifically a high-efficiency micro-wind cluster power generation device. Background Technology

[0002] As wind energy utilization technology expands to distributed, low-wind-speed areas, the efficient and reliable operation of small wind power generation devices in low-wind environments has become an urgent problem to be solved.

[0003] Currently, most traditional small wind power generation devices adopt a single-rotor structure, which has a relatively high starting wind speed and is difficult to generate electricity continuously and effectively in areas with low average annual wind speeds. To improve wind energy capture capabilities under light wind conditions, existing technologies often employ structures such as wind collectors, guide tubes, and speed-increasing gearboxes. However, in actual use, these structures often only perform simple contraction and acceleration of the incoming flow, failing to adequately utilize the energy in the lateral and wake regions of the impeller. Consequently, the pressure difference across the impeller is limited. In some devices, due to the multiple transmission structures, the starting wind speed is too high. During unstable wind speeds or the power generation start-up phase, the impeller shaft system is prone to axial movement and impact, affecting the bearings, rotor, and overall operational reliability of the unit. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency micro-wind cluster power generation device to solve the problems mentioned in the background art, such as insufficient energy utilization of micro-wind and easy generation of axial impact, which in turn damages the bearings.

Both the base and the reverse auxiliary wheel are provided with annular grooves that communicate with the inclined air channels. One end of the guide pipe is connected to the annular groove, and the other end is connected to the end face of the outer cylinder.

[0010] The buffer assembly includes a fixed cylinder, which is fixedly connected to the outer cylinder. Inside the fixed cylinder are a bearing and a first permanent magnet connected to the rotating shaft. A second permanent magnet is fixedly connected inside the fixed cylinder, with the first permanent magnet and the second permanent magnet having the same pole facing each other.

[0011] As a further embodiment of the present invention: the guide cone is frustum-shaped, with a through air inlet channel in the middle, and a lateral tangential air duct in the inclined surface of the guide cone. One end of the lateral tangential air duct is perpendicular to the inclined surface, and the other end obliquely penetrates the guide cone and communicates with the air inlet channel.

[0012] As a further embodiment of the present invention: the dual-rotor generator is fixedly connected inside the outer cylinder, the lower end of the outer cylinder is fixedly connected to the base, the reverse auxiliary wheel is rotatably connected to the lower end of the base, and the contact surfaces of the base and the reverse auxiliary wheel are both provided with annular grooves; a number of inclined air channels are evenly provided on the surface of the reverse auxiliary wheel, the inclined air channels are inclined in the same direction as the lateral tangential air channels, and the end of the inclined air channel near the dual-rotor generator is connected to the annular groove.

[0013] As a further embodiment of the present invention: an odd number of guide plates are provided, the guide plates are inclined, one end of the guide plate is fixedly connected to the guide cone, the other end of the guide plate is fixedly connected to the inclined surface of the outer cylinder, and the outer cylinder does not contact the guide cone.

[0014] As a further aspect of the present invention: a plurality of power blades are fixedly connected inside the impeller, the cross-section of the power blades is trapezoidal, a rotating shaft is fixedly connected in the middle of the impeller, the lower end of the rotating shaft passes through the end face of the outer cylinder and the fixed cylinder in sequence, and is slidably connected to one end of the magnetic coupling.

[0015] As a further embodiment of the present invention: the end of the magnetic coupling one that is away from the fixed cylinder is fixedly connected to one end of the dual rotor generator, the other end of the dual rotor generator is fixedly connected to one end of the magnetic coupling two, the other end of the magnetic coupling two passes through the base and is fixedly connected to the reverse auxiliary wheel, and the surfaces of the magnetic coupling one and the magnetic coupling two are fixedly connected to the outer cylinder.

[0016] As a further embodiment of the present invention: the inner wall of the bearing is fixedly connected to the rotating shaft, the outer side of the bearing is slidably connected to the inner wall of the fixed cylinder, the end of the bearing near the magnetic coupling is fixedly connected to the permanent magnet, and the permanent magnet is fixedly connected to the fixed cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The airflow is concentrated and accelerated through the air inlet channel of the guide cone, and a portion of the cone surface diverted airflow is converted into tangential airflow in conjunction with the side tangential air duct, thereby impacting the drive groove on the side of the impeller and providing additional tangential driving force for the impeller, thereby reducing the starting wind speed and facilitating starting and continuous operation under light wind conditions.

[0019] 2. The airflow passing through the gap is rectified into a directional swirling flow by the inclined guide plate. After being discharged through the guide groove with gradually increasing width on the outer cylinder side wall, the swirling airflow forms a central low-pressure zone in the area behind the impeller under centrifugal force, thereby increasing the air pressure difference before and after the impeller, increasing the wind speed passing through the impeller, and thus improving the utilization of wind energy under light wind conditions.

[0020] 3. Through the guide pipe, annular groove, reverse auxiliary wheel, and buffer assembly, part of the exhaust flow discharged from the impeller is guided to the reverse auxiliary wheel. The reaction force of the exhaust flow drives the reverse auxiliary wheel to rotate, which in turn drives the two ends of the dual rotor generator to rotate in opposite directions. The superposition of relative speeds helps to improve power generation efficiency. At the same time, the buffer assembly, together with the inclined pipe, forms a double buffer of magnetic force and air pressure, which can effectively reduce the axial impact of the impeller during unstable wind speed or startup, avoid impeller collision, and improve the reliability of the whole machine operation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 This invention provides a technical solution: a high-efficiency micro-wind cluster power generation device, comprising a main body 1, which is composed of an outer cylinder 2, a guide cone 3, and a base 12. The base 12 is fixedly connected to the lower end of the outer cylinder 2. Several evenly arranged guide pipes 83 and inclined pipes 84 are fixedly arranged inside the outer cylinder 2. A buffer assembly 6 is also provided inside the outer cylinder 2, which can effectively prevent the impeller 5 from colliding when the wind is unstable. Multiple guide grooves 21 are opened on the side wall of the outer cylinder 2, and a lateral tangential air duct 31 is opened on the surface of the guide cone 3. An impeller 5 is coaxially assembled inside the outer cylinder 2. A reverse auxiliary wheel 8 is rotatably connected to the lower end of the base 12 of the dual rotor generator 9. The reverse auxiliary wheel 8 can improve the power generation efficiency. A drive groove 51 is circumferentially opened on the side of the impeller 5. The air outlet direction of the lateral tangential air duct 31 is directly opposite to the drive groove 51, so that tangential airflow can be output to assist in driving the impeller 5 to rotate. The two rotor ends of the dual rotor generator 9 are respectively equipped with a magnetic coupling 10 and a magnetic coupling 2 11. The magnetic coupling 10 is driven by the impeller 5, and the magnetic coupling 2 11 is driven by the reverse auxiliary wheel 8. At this time, the two rotors rotate in opposite directions to generate electricity.

[0033] The buffer assembly 6 mainly includes a fixed cylinder 63, which is fixedly connected to the inner wall of the outer cylinder 2 near the guide cone 3. The fixed cylinder 63 is equipped with a bearing 64 connected to the impeller 5 and a permanent magnet 61. A permanent magnet 62 is fixedly connected to the inner wall of the fixed cylinder 63. The permanent magnet 61 and the permanent magnet 62 are arranged opposite each other with the same pole, so that they can form axial buffer support by relying on the repulsive force of the same pole.

[0034] Both the guide cone 3 and the outer cylinder 2 are frustum-shaped. The guide cone 3 is coaxially arranged at the end of the outer cylinder 2 away from the base 12. An axially penetrating air inlet channel 4 is opened in the middle of the guide cone 3 to form the main air inlet passage. Several sets of lateral tangential air ducts 31 are opened on the inclined surface of the guide cone 3. The air inlet end of the lateral tangential air duct 31 is opened perpendicular to the cone surface, and its air outlet end is obliquely downward through the side wall of the guide cone 3 and connected to the air inlet channel 4. In this way, the airflow diverted by the cone surface can be rectified and converted into tangential high-speed airflow, which then impacts the drive groove 51 on the side of the impeller 5, providing additional tangential driving force for the impeller 5, while reducing the starting wind speed.

[0035] The air inlet end of the outer cylinder 2 is connected and fixed to the guide cone 3 via several guide plates 7. An odd number of guide plates 7 are used to reduce the risk of resonance. The guide plates 7 are evenly arranged in an inclined shape. One end of each guide plate 7 is fixedly connected to the bottom surface of the guide cone 3, and the side of each guide plate 7 is fixedly connected to the inner wall of the inclined surface of the air inlet end of the outer cylinder 2. Through the guide plates 7 and the inclined surface of the outer cylinder 2, the width of the guide groove 21 gradually increases along the air outlet direction. The outer cylinder 2 and the guide cone 3 do not contact each other, and an annular gap is formed between them. The annular gap and the guide... The narrow end of the channel 21 is connected. Through the odd number of inclined guide plates 7 and the guide channel 21, the airflow flowing through the annular gap can be rectified into a directional swirling flow. The guide channel 21 on the side wall of the outer cylinder 2 is arranged circumferentially, and the width of the channel gradually increases along the air outlet direction. When the swirling airflow is discharged from the guide channel 21, the airflow is thrown to the outer wall of the guide channel 21. Under the action of centrifugal force, a low-pressure vortex core area can be formed in the area behind the impeller 5, thereby increasing the air pressure difference before and after the impeller 5, further increasing the wind speed flowing through the impeller 5, and enhancing the efficiency of wind energy utilization in light breezes.

[0036] Several power blades 52 are fixedly connected to the inner wall of the impeller 5. The cross-section of the power blades 52 is trapezoidal, which can improve the wind energy capture capacity under low wind speed. A rotating shaft 53 is fixedly connected to the center of the impeller 5. The lower end of the rotating shaft 53 passes through the inner end face of the outer cylinder 2 and the fixed cylinder 63 of the buffer assembly 6. The end of the rotating shaft 53 is axially slidably connected to one end of the magnetic coupling 10 through a spline. The other end of the magnetic coupling 10 is fixedly connected to the rotor end of the upper end of the dual rotor generator 9. The rotor end of the lower end of the dual rotor generator 9 is fixedly connected to one end of the magnetic coupling 11. The other end of the magnetic coupling 11 passes downward through the base 12 and is fixedly connected to the center of the reverse auxiliary wheel 8. The housings of the magnetic coupling 10 and the magnetic coupling 11 are both fixedly connected to the internal structure of the outer cylinder 2. Non-contact magnetic transmission is adopted, thus eliminating the need for a moving sealing structure and effectively reducing transmission wear and maintenance costs. The dual rotor generator 9 is fixedly installed in the center position inside the outer cylinder 2.

[0037] The reverse auxiliary wheel 8 is rotatably mounted on the lower end face of the base 12. Coaxial annular grooves 81 are provided on the contact surfaces of the base 12 and the reverse auxiliary wheel 8. When the reverse auxiliary wheel 8 rotates, the annular grooves 81 remain connected, forming an annular airflow distribution cavity to maintain the continuous rotation of the reverse auxiliary wheel 8. Several inclined air ducts 82 are evenly provided on the surface of the reverse auxiliary wheel 8. The inclined air ducts 82 are inclined in the same direction as the lateral tangential air ducts 31. At this time, the impeller 5 and the reverse auxiliary wheel 8 rotate in opposite directions. The upper end of the inclined air duct 82 is connected to the annular groove 81, and the lower end is inclined outward to discharge. The airflow introduced by the guide pipe 83 is distributed through the annular groove 81 and enters each inclined air duct 82. The reaction force when discharged drives the reverse auxiliary wheel 8 to rotate in the opposite direction, thereby driving the lower rotor of the generator to rotate in the opposite direction to the upper rotor, superimposing the relative speed and improving the power generation efficiency.

[0038] The upper end of the guide pipe 83 passes through the inner end face of the outer cylinder 2, with its opening facing the air outlet side of the impeller 5. The lower end of the guide pipe 83 is fixedly connected to the base 12, and the inner cavity of the guide pipe 83 communicates with the annular groove 81 of the base 12. The annular groove 81 communicates with the inclined air duct 82 on the reverse auxiliary wheel 8. An inclined pipe 84 is fixedly connected to the side wall of each guide pipe 83. The end of the inclined pipe 84 away from the guide pipe 83 communicates with the inner cavity of the fixed cylinder 63, so that the inner cavity of the fixed cylinder 63 is connected to the internal air passage of the guide pipe 83. This allows the high-speed airflow in the guide pipe 83 to be drawn into the fixed cylinder 63 through the inclined pipe 84 using the Venturi effect, thereby forming a low-pressure auxiliary buffer force. The fixed cylinder 63 is the same as... The bushing is located on the outside of the rotating shaft 53. The inner wall of the bearing 64 is fixedly connected to the rotating shaft 53. The outer ring of the bearing 64 is slidably fitted with the inner wall of the fixed cylinder 63. The bearing 64 can effectively reduce the friction of the impeller 5 rotation. The end of the bearing 64 near the magnetic coupling 10 is fixedly connected to the permanent magnet 61. The permanent magnet 62 is fixedly installed on the inner wall of the fixed cylinder 63 near the magnetic coupling 10. The permanent magnet 61 and the permanent magnet 62 have the same pole facing each other. The magnetic force of the like poles repulsing each other forms the first axial buffer. The rotating shaft 53 can slide slightly axially with the impeller 5, thereby cooperating with the double buffering effect of permanent magnet repulsion and air pressure suction to offset the axial impact caused by wind pressure fluctuation.

[0039] In actual use, the main body 1 is horizontally positioned at a high location. When a light breeze passes directly over the main body 1, the wind comes into contact with the guide cone 3. At this time, the main airflow enters the air inlet channel 4 in the middle of the guide cone 3 and comes into contact with the impeller 5. The wind also comes into contact with the power blade 52, thereby driving the impeller 5 to rotate. Simultaneously, some airflow enters the lateral tangential air duct 31 on the inclined surface of the guide cone 3 and is ejected obliquely at the end, coming into contact with the drive groove 51 on the side of the impeller 5, thereby further increasing the speed of the impeller 5. Subsequently, the wind passes through the impeller 5 and comes into contact with the end face of the outer cylinder 2. At this time, the main airflow flows out from the side of the outer cylinder 2, during which it comes into contact with the guide plate 7. Under the action of the guide plate 7, the airflow is rectified and ejected from the guide groove 21 in a swirling manner. As the width of the guide groove 21 gradually increases, the airflow rotates and generates centrifugal force, which in turn significantly reduces the static pressure in the area between the impeller 5 at the beginning of the guide groove 21 and the end face of the outer cylinder 2, forming a central low-pressure zone. This low pressure further increases the wind speed, thereby increasing the rotational speed of the impeller 5. Meanwhile, the remaining airflow directly enters the guide pipe 83 in the outer cylinder 2, passes through the guide pipe 83 and enters the annular groove 81 of the base 12, and is then ejected along the inclined air duct 82 of the reverse auxiliary wheel 8. At this time, the reverse auxiliary wheel 8 begins to rotate.

[0040] When the wind initially contacts the impeller 5, the impeller 5 will be pushed towards the base 12 under the action of wind pressure. At this time, the shaft 53 will slide accordingly, which will cause the permanent magnet 61 to gradually approach the permanent magnet 62 and generate a repulsive force. When the wind passes through the guide pipe 83, its flow velocity is higher than that of the air in the inclined pipe 84, which will reduce the air pressure in the fixed cylinder 63 connected to the inclined pipe 84 and act on the back of the permanent magnet 61. At this time, the permanent magnet 61 can be effectively buffered under the action of repulsive force and low pressure, thereby avoiding collisions when the wind speed is unstable and in the initial stage of power generation.

[0041] When the impeller 5 rotates, the shaft 53 rotates synchronously, and then drives one rotor end of the dual rotor generator 9 to rotate through the first magnetic coupling. When the reverse auxiliary wheel 8 rotates, it can drive the other rotor end of the dual rotor generator 9 to rotate through the second magnetic coupling. The two rotate in opposite directions, thus generating electricity.
