Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a micro-wind power generation device with a multi-blade array layout. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. At present, wind power is used to drive the blades to rotate, thereby driving the generator to work, so as to achieve wind power generation. However, some wind turbines have high requirements for wind power, and the kinetic energy of low-speed breeze is not enough to drive the wind turbine. In order to improve the energy utilization of wind power, a breeze power generation device with a multi-blade array layout is proposed.

[0003] In the prior art, most breeze power generation devices use more blades to increase the windward area of ​​the blades so that the breeze can also drive the generator to rotate through the blades. In this type of wind turbine, the blades are mostly V-shaped. Although blades of this shape can provide greater power when facing the wind, in headwind, the wind will still act on the blades, causing the rotating force and rotation speed of the rotating shaft components to decrease, resulting in increased wind energy loss, which in turn leads to the existing breeze power generation still having a high degree of requirements for wind power.

[0050] Combine the following Figures 1 to 6 As shown, an embodiment of the present invention provides a micro-wind power generation device with a multi-blade array layout, comprising:

[0051] A power generation component, a rotating shaft 4 is arranged on the top of the power generation component;

[0052] Multiple blade mechanisms, wherein the multiple blade structures are fixed on the side wall of the rotating shaft 4 at equal distances;

[0053] An adjusting component, the adjusting component is arranged on the top of the rotating shaft 4;

[0054] The blade mechanism includes:

[0055] A first fixing plate 11 and a second fixing plate 12, both of which are fixed on the side wall of the rotating shaft 4, and the first fixing plate 11 and the second fixing plate 12 are distributed up and down;

[0056] Two support plates 13, the two support plates 13 are fixed between the first fixing plate 11 and the second fixing plate 12;

[0057] A plurality of blade assemblies, each of which is rotatably disposed between two support plates 13;

[0058] The transmission assembly is arranged on the top of the first fixing plate 11, and is used to cooperate with the adjustment assembly to change the state of the blade assembly.

[0059] By cooperating with the transmission assembly and the adjustment assembly, the state of the blade assembly is adjusted to increase or decrease the force of the wind on the blade assembly, thereby achieving that when the blade assembly rotates, when the blade assembly rotates along the wind direction, the wind force acts on the blade assembly to push the rotating shaft 4 to rotate through the blade assembly, and when the blade assembly rotates against the wind direction, the wind force acting on the blade assembly is limited, thereby avoiding the loss of kinetic energy of the wind, so as to improve the effect of breeze power generation.

[0060] Furthermore, the power generation component includes:

[0061] A base 1 is provided, a chassis 2 is provided on the top of the base 1, a generator is provided in the chassis 2, and a rotating shaft 4 is fixed to a power input shaft of the generator;

[0062] The supporting sleeve 3 is fixed on the top of the chassis 2 , and the rotating shaft 4 passes through the supporting sleeve 3 .

[0063] When wind acts on the blade assembly, it drives the shaft 4 to rotate. The support of the support sleeve 3 ensures the stability of the shaft 4 during rotation. At the same time, the coaxiality of the shaft 4 and the generator power input is ensured to avoid energy loss and improve the stability of the device.

[0064] Further, the adjustment component includes:

[0065] A connecting seat 5, the connecting seat 5 is rotatably arranged on the top of the rotating shaft 4;

[0066] A plurality of connecting frames 6, wherein the plurality of connecting frames 6 are all fixed to the connecting seat 5;

[0067] The annular plate 7 is fixed to the plurality of connecting frames 6. A plurality of first strong magnets 10 are arranged at equal distances in a semicircle on one side of the bottom of the annular plate 7, and the N poles of the first strong magnets 10 are located at the bottom. A plurality of third strong magnets 23 are arranged at equal distances in a semicircle on the other side of the bottom of the annular plate 7, and the N poles of the third strong magnets 23 are located at the top.

[0068] A fixing rod 8 is fixed on the top of the connecting seat 5 , and a weather vane 9 is fixed on the top of the fixing rod 8 .

[0069] When a breeze blows, the weather vane 9 with a larger area is pushed to rotate, and then the connecting seat 5 is driven to rotate through the fixing rod 8. During the rotation of the connecting seat 5, the annular plate 7 is driven to rotate through the connecting frame 6, and then the positions of the first strong magnet 10 and the third strong magnet 23 at the bottom of the annular plate 7 are adjusted. With the action of the transmission component, when the blade assembly rotates in the direction of wind, the blade assembly is below the multiple third strong magnets 23, that is, the blade 17 is in an unfolded state, increasing the force of wind acting on the blade 17. Conversely, when the rotation direction of the blade assembly is opposite to the wind direction, the blade assembly is below the multiple first strong magnets 10, that is, the blade is in a flipped state. At this time, the wind force and the effective area of ​​the blade 17 are only the thickness of the blade 17, that is, the loss of wind kinetic energy is reduced, ensuring the effect of breeze power generation.

[0070] Further, the blade assembly includes:

[0071] A shaft body 16, the shaft body 16 is rotatably disposed between the two support plates 13;

[0072] The blade 17 is fixed to the shaft 16 and has an arc-shaped structure.

[0073] Furthermore, it also includes:

[0074] The gear 15 is rotatably disposed on the side wall of one of the support plates 13 , and the gear 15 and the shaft 16 are fixed.

[0075] Furthermore, the transmission assembly includes:

[0076] Two support frames 18, both of which are fixed on the top of the first fixed plate 11, and a support shaft is fixed between the two support frames 18;

[0077] A transmission rod 19, a through hole 20 is formed on a side wall of the transmission rod 19, and the through hole 20 is close to one end of the transmission rod 19, and the support shaft passes through the through hole 20;

[0078] A connecting hole is provided at the top of the first fixing plate 11 near the supporting frame 18, a square rod 22 is slidably arranged in the connecting hole, and the square rod 22 is rotatably connected to the transmission rod 19;

[0079] The rack 14 is slidably disposed on the side wall of one of the support plates 13 , and the rack 14 is meshed with a plurality of gears 15 , and the rack 14 is fixed to the square rod 22 .

[0080] Furthermore, a second strong magnet 21 is fixed to one end of the transmission rod 19 away from the support frame 18 .

[0081] The second strong magnet 21 below the first strong magnet 10 is subjected to the repulsive force, and the second strong magnet 21 descends, so that the transmission rod 19 rotates around the support shaft, that is, the end of the transmission rod 19 away from the second strong magnet 21 rises. Since the through hole 20 is located at one end of the transmission rod 19, under the action of the lever, the transmission rod 19 can drive the rack 14 to rise through the square rod 22, and then drive each gear 15 to rotate, and each shaft body 16 is rotated through the gear 15, so that the blade 17 on the shaft body 16 is turned over by ninety degrees, that is, the blade surface of the blade 17 faces downward. At this time, the contact area between the blade 17 and the airflow is the thickness of the blade 17. Therefore, when the blade 17 rotates in this state, the overall rotation speed of the device will not be reduced due to wind resistance;

[0082] On the contrary, the second strong magnet 21 below the third strong magnet 23 is acted upon by suction, the second strong magnet 21 rises, the end of the transmission rod 19 away from the second strong magnet 21 descends, and through the corresponding square rod 22, rack 14 and gear 15, the corresponding blade 17 faces the wind direction, so that the breeze can act on the surface of the blade 17, thereby dragging the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the generator is driven to work, thereby realizing power generation.

[0083] The specific working method is: when in use, fix the base 1 on a suitable ground, and then build the device;

[0084] During power generation, when a breeze blows, the wind vane 9 with a larger area is pushed to rotate, and then the connecting seat 5 is driven to rotate through the fixing rod 8. During the rotation of the connecting seat 5, the annular plate 7 is driven to rotate through the connecting frame 6;

[0085] After the annular plate 7 stops rotating, the second strong magnet 21 below the first strong magnet 10 is subjected to the repulsive force, and the second strong magnet 21 descends, causing the transmission rod 19 to rotate around the supporting shaft, that is, the end of the transmission rod 19 away from the second strong magnet 21 rises. Since the through hole 20 is located at one end of the transmission rod 19, under the action of the lever, the transmission rod 19 can drive the rack 14 to rise through the square rod 22, thereby driving each gear 15 to rotate, and each shaft body 16 is rotated through the gear 15, so that the blade 17 on the shaft body 16 is turned over by ninety degrees, that is, the blade surface of the blade 17 faces downward. At this time, the contact area between the blade 17 and the airflow is the thickness of the blade 17. Therefore, when the blade 17 rotates in this state, the overall rotation speed of the device will not be reduced due to wind resistance;

[0086] On the contrary, the second strong magnet 21 below the third strong magnet 23 is acted upon by suction, the second strong magnet 21 rises, the end of the transmission rod 19 away from the second strong magnet 21 descends, and through the corresponding square rod 22, rack 14 and gear 15, the corresponding blade 17 faces the wind direction, so that the breeze can act on the surface of the blade 17, thereby dragging the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the generator is driven to work, thereby realizing power generation.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
