Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to a wind power generator with adjustable blade angles. Background Art

[0002] Wind energy is a renewable and clean energy source. Wind power generation is a technology that uses wind energy to generate electricity. Due to the advantages of wind power generation such as cleanness, environmental protection, strong renewability and low operating costs, it is widely used around the world and plays an important role in achieving global energy transformation and responding to climate change.

[0003] Wind turbines can be installed on land or at sea. They are devices that can convert wind energy in the natural environment into electrical energy. The working principle of a wind turbine is to use wind to drive the wind wheel to rotate, thereby converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy through a generator. The blades on existing wind turbines are mostly fixed and cannot be adjusted. However, the wind direction and wind speed are variable in the natural environment. Fixed blades cannot fully utilize wind energy resources, and wind turbines cannot always maintain an efficient and stable working state. Moreover, when the wind speed in the natural environment is fast, driving the wind wheel to rotate too fast will also cause blade damage, and even wind turbine failure and shutdown. Summary of the invention

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0043] According to an embodiment of the present invention, on the one hand, a wind turbine with adjustable blade angle is provided, and the wind turbine includes: a mounting assembly, a plurality of blade assemblies 2 and an angle adjustment assembly. The mounting assembly includes: a base 11, a sleeve 12 and a rotating drum 13, wherein the sleeve 12 is arranged on the base 11, and the rotating drum 13 is rotatably arranged at the top of the sleeve 12; the plurality of blade assemblies 2 are arranged at intervals along the circumference of the rotating drum 13, and one end of the blade assemblies 2 extends into the rotating drum 13; the angle adjustment assembly includes: a wind speed detection device 31, a driving mechanism and an angle adjustment mechanism 33, wherein the wind speed detection device 31 is arranged on the outer wall of the rotating drum 13, the driving mechanism is arranged in the mounting assembly, and the wind speed detection device 31 is communicatively connected with the driving mechanism, and the angle adjustment mechanism 33 is arranged in the mounting assembly, wherein the power input end thereof is connected with the driving mechanism, and the power output end thereof is connected with one end of the blade assembly 2 extending into the rotating drum 13.

[0044] The base 11 is in the shape of a rectangular parallelepiped and can be set on the ground. The base 11 has a cavity inside. The sleeve 12 is hollow, and the bottom end is fixedly set on the base 11, and the inside of the sleeve 12 is connected with the inside of the base 11. The rotating drum 13 is similar in structure to the sleeve 12 and is also hollow, and is connected with the inside of the sleeve 12. The diameter of the rotating drum 13 is larger than that of the sleeve 12, but the height of the rotating drum 13 is much smaller than that of the sleeve 12. Multiple groups of blade assemblies 2 are arranged around the rotating drum 13. In this embodiment, a total of four groups of blade assemblies 2 are arranged, and the angle between two adjacent groups of blade assemblies 2 is 90°. When the wind hits the surface of the blade assembly 2, it can drive the blade assembly 2 and the rotating drum 13 to rotate together, thereby utilizing wind energy to convert into electrical energy.

[0045] Furthermore, in this embodiment, the wind speed detection device 31 is arranged at the center position of the top surface of the rotating drum 13 to detect parameters such as wind direction and wind speed in the natural environment, and convert the relevant parameters into electrical signals, which are transmitted to the driving mechanism. After receiving the relevant electrical signals, the driving mechanism drives the angle adjustment mechanism 33 to perform corresponding actions, thereby driving the blade assembly 2 to rotate and change its angle.

[0046] The wind speed detection device 31 can monitor the wind direction and wind speed of the natural wind, and control the driving mechanism according to the monitoring data, and then control the angle adjustment mechanism 33 by controlling the driving mechanism, and finally adjust the angle of the blade assembly 2 through the angle adjustment mechanism 33. That is to say, when the wind direction changes, the angle of the blade assembly 2 can be adjusted according to the wind direction, so that the blade assembly 2 is consistent with the wind direction, so that the wind turbine can make full use of wind energy, reduce wind impact, and the wind turbine can continue to work in an efficient and stable working state. When the wind speed is too high, the angle of the blade assembly 2 can be adjusted to increase the wind resistance and reduce the rotation speed of the blade assembly 2, thereby avoiding the blade assembly 2 from rotating too fast and being damaged.

[0047] In one embodiment, the angle adjustment mechanism 33 includes: a transmission rod 331, a first bevel gear 332 and a second bevel gear 333. One end of the transmission rod 331 is located at the base 11 and is connected to the driving mechanism, and the other end extends from the sleeve 12 into the rotating drum 13. The first bevel gear 332 is arranged on the transmission rod 331, and the end of each blade assembly 2 extending into the rotating drum 13 is provided with a second bevel gear 333, and the second bevel gear 333 is meshed with the first bevel gear 332.

[0048] The transmission rod 331 is a rod with a hollow interior, and the rod body extends from the base 11 to the drum 13, that is, one end of the transmission rod 331 is located in the base 11 so as to be connected with the driving mechanism. In addition, a mounting plate is provided on the rod body of the transmission rod 331 located inside the base 11, and the mounting plate is fixedly provided on the transmission rod 331 and can rotate with the transmission rod 331, and the diameter of the mounting plate is larger than the diameter of the rod body of the transmission rod 331. The other end of the transmission rod 331 is located in the drum 13, and a first bevel gear 332 is provided at its end. The first bevel gear 332 is located at the lower side of the second bevel gear 333, and the first bevel gear 332 can mesh with the second bevel gear 333 provided on one end of each blade assembly 2 extending into the drum 13. In this embodiment, four groups of blade assemblies 2 are provided, that is, the first bevel gear 332 meshes with four second bevel gears 333 at the same time. In this way, when the first bevel gear 332 rotates, the second bevel gear 333 can be driven to rotate, and the blade assembly 2 is also driven to rotate synchronously, so that the angle of the blade assembly 2 can be adjusted.

[0049] In one embodiment, the driving mechanism includes: a lifting driving component and a rotation driving component. The lifting driving component is used to drive the transmission rod 331 to rise and fall along the height direction of the sleeve 12, and the rotation driving component is used to drive the transmission rod 331 to rotate around the axial direction of the sleeve 12.

[0050] The lifting drive member is used to change the meshing state of the first bevel gear 332 and the second bevel gear 333, that is, when the angle of the blade assembly 2 needs to be adjusted, the lifting drive member drives the transmission rod 331 to rise, so that the first bevel gear 332 is meshed with the second bevel gear 333, and then the transmission rod 331 and the first bevel gear 332 are driven to rotate by the rotating drive member, thereby driving the second bevel gear 333 and the blade assembly 2 to rotate synchronously to achieve angle adjustment. When the angle of the blade assembly 2 does not need to be adjusted, the blade assembly 2 and the rotating drum 13 need to rotate to generate electricity using wind energy. At this time, in order to prevent the first bevel gear 332 from interfering with the second bevel gear 333, the lifting drive member needs to drive the transmission rod 331 to move up and down, so that the first bevel gear 332 is separated from the second bevel gear 333.

[0051] In one embodiment, the lifting drive component includes: a lifting rod 3211, the lifting rod 3211 is arranged in the base 11, the part of the transmission rod 331 located at the base 11 is provided with a mounting plate, and the driving end of the lifting rod 3211 is connected to the mounting plate.

[0052] The lifting direction of the lifting rod 3211 is along the height direction of the sleeve 12. The mounting end of the lifting rod 3211 is set on the bottom surface of the base 11, and its driving end is connected to the bottom surface of the mounting plate on the transmission rod 331, so that when the lifting rod 3211 is extended or retracted, it can drive the transmission rod 331 to rise and fall as a whole. One lifting rod 3211 can be set, or multiple lifting rods 3211 can be set around the transmission rod 331. When multiple lifting rods 3211 are set, the force on the mounting plate is more uniform, and the lifting process of the transmission rod 331 is more stable. The lifting rod 3211 can adopt various linear drive devices such as electric telescopic rods and pneumatic telescopic rods.

[0053] In one embodiment, a slider 3212 is provided between the driving end of the lifting rod 3211 and the mounting plate.

[0054] Since the transmission rod 331 rotates under the driving of the rotating driving member, the mounting plate also rotates synchronously, so that the mounting plate rubs against the lifting rod 3211, and the two will wear each other, and when the friction is large, it will also affect the rotation of the rotating rod. By setting the slider 3212, the friction between the mounting plate and the lifting rod can be greatly reduced, and the rotation of the rotating rod will not be affected.

[0055] In one embodiment, the rotating driving component includes: a driving motor 3221, a first transmission wheel 3222 and a second transmission wheel 3223. The driving motor 3221 is arranged in the base 11, and its output shaft is connected to the first transmission wheel 3222. One end of the transmission rod 331 located in the base 11 is connected to the second transmission wheel 3223. A transmission belt 3224 is wound around the first transmission wheel 3222 and the second transmission wheel 3223.

[0056] The driving motor 3221 is disposed on the top surface of the base 11, and the driving motor 3221 can drive the first transmission wheel 3222 to rotate, and then drive the second transmission wheel 3223 and the transmission rod 331 to rotate through the transmission belt 3224. The second transmission wheel 3223 is longer than the first transmission wheel 3222, because the second transmission wheel 3223 will rise and fall with the transmission rod 331, so as to ensure that the second transmission wheel 3223 can still be connected with the transmission belt 3224 when it rises and falls.

[0057] In one embodiment, the wind turbine further includes a wind turbine starting assembly, and the wind turbine starting assembly is used to drive the blade assembly 2 to rotate.

[0058] When the wind turbine is ready to start working, the fan starter assembly can first drive the blade assembly 2 to rotate, and then the wind can be used to drive the blade assembly 2 to rotate, which can reduce the resistance and difficulty of the wind directly driving the blade assembly 2 to rotate.

[0059] In one embodiment, the fan starting assembly includes: a starting motor 41, a rotating shaft 42 and an inner cover shell 43. The starting motor 41 is arranged in the transmission rod 331, one end of the rotating shaft 42 is connected to the driving end of the starting motor 41, and the other end of the rotating shaft 42 is connected to the inner cover shell 43. The inner cover shell 43 is located on the inner side of the rotating drum 13 and is fixedly connected to the rotating drum 13.

[0060] The inner cover shell 43 is located inside the rotating drum 13, and covers the outside of the first bevel gear 332 and the second bevel gear 333. The inner cover shell 43 is coaxially arranged with the rotating drum 13 and is fixedly connected with the rotating drum 13. The interior of the transmission rod 331 is hollow, which can be used to set the starting motor 41 and the rotating shaft 42. The starting motor 41 is located at the bottom of the sleeve 12, and it is connected to one end of the rotating shaft 42, and the other end of the rotating shaft 42 extends upward until it is connected to the inner cover shell 43. When the starting motor 41 is working, it can drive the rotating shaft 42 to rotate, and then drive the inner cover shell 43, the rotating drum 13 and the blade assembly 2 to rotate through the rotating shaft 42.

[0061] In one embodiment, a clamping block 44 is disposed on the top surface of the inner cover shell 43 , and the clamping block 44 is connected to the rotating drum 13 .

[0062] The inner housing 43 includes a housing 431 and a top cover 432. The housing 431 is cylindrical and covers the outside of the first bevel gear 332 and the second bevel gear 333. The top cover 432 is arranged at the top of the housing 431. A plurality of blocks 44 are arranged on the top cover 432. The blocks 44 are in a square shape and are welded and fixed to the rotating drum 13.

[0063] In one embodiment, the blade assembly 2 includes: a fan blade 21 and a connecting rod 22 , wherein the fan blade 21 is disposed at one end of the connecting rod 22 , and the other end of the connecting rod 22 extends into the rotating drum 13 .

[0064] The fan blade 21 is located outside the rotating drum 13 and has a flat overall shape. The connecting rod 22 is a round rod, one end of which is connected to the fan blade 21, and the other end passes through the rotating drum 13 and the inner housing 43, extends out of the inner housing 43, and is provided with a second bevel gear 333. The fan blade 21 and the connecting rod 22 can rotate synchronously with the second bevel gear 333.

[0065] In other embodiments, the fan blade 21 may be in other shapes such as a willow leaf shape.

[0066] The working process of the wind turbine provided by this embodiment is described as follows:

[0067] The starting motor 41 is started first, and the starting motor 41 drives the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it drives the inner cover 43 and the rotating drum 13 connected thereto to rotate. The connecting rod 22 in the blade assembly 2 passes through the inner cover 43 and the rotating drum 13, so when the inner cover 43 and the rotating drum 13 rotate, the connecting rod 22 and the fan blades 21 can be driven to rotate synchronously, thereby realizing the rotation of multiple groups of blade assemblies 2. During the rotation of the blade assembly 2, the wind will also act on the blade assembly 2, further driving the blade assembly 2 to rotate and accelerating the rotation speed of the blade assembly 2, so that the blade assembly 2 can use wind energy to generate electricity.

[0068] The wind speed detection device 31 detects the wind direction and wind speed in the natural environment in real time. When the blade assembly 2 needs to be adjusted, a control signal will be transmitted to the driving mechanism. At this time, the lifting rod 3211 will first lift upward to make the transmission rod 331 rise, so that the first bevel gear 332 on the transmission rod 331 and the second bevel gear 333 on the connecting rod 22 in the blade assembly 2 are engaged. Then the driving motor 3221 is started, driving the transmission rod 331 to rotate a certain angle, and the first bevel gear 332 on the synchronous transmission rod 331 will also rotate a corresponding angle, thereby driving the second bevel gear 333 to rotate a certain angle to adjust the angle of the blade assembly 2. In the normal power generation process, the angle of the blade assembly 2 is generally adjusted to keep it consistent with the wind direction, thereby reducing wind resistance, making full use of wind energy, speeding up the rotation speed of the blade assembly 2, and improving power generation efficiency. However, when the wind speed in the natural environment is too fast, if the rotation speed of the blade assembly 2 will also become faster and faster, this may cause damage to the blade assembly 2 and malfunction of the wind turbine. Therefore, when the wind speed is fast, it is necessary to adjust the angle of the blade assembly 2 to increase the wind resistance, so as to reduce the rotation speed of the blade assembly 2 and ensure the safe operation of the wind turbine.

[0069] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
