Referring to fig. 1 and 2, a wind power generation apparatus 100 includes a wind turbine structure 10, a first rotating shaft 20a, a first bevel gear 30a, a first permanent magnet suspension bearing 40a, a second rotating shaft 20b, a second bevel gear 30b, a second permanent magnet suspension bearing 40b, and a generator 50. The wind wheel structure 10 includes a blade 101 and an air box 102, the blade 101 is accommodated in the air box 102, the blade 101 is disposed on the first rotating shaft 20a, a direction in which an axis of the first rotating shaft 20a is located is a first direction D1, the blade 101 is used for supplying wind force to enable the first rotating shaft 20a to rotate around the first direction D1, the first bevel gear 30a is disposed on the first rotating shaft 20a, the first rotating shaft 20a is inserted into the first permanent magnet suspension bearing 40a, a direction of a force acting on the first rotating shaft 20a by the first permanent magnet suspension bearing 40a is opposite to a direction of a force acting on the first rotating shaft 20a by the first bevel gear 30a, the second rotating shaft 20b is disposed perpendicular to the first rotating shaft 20a, the second bevel gear 30b is disposed on the second rotating shaft 20b, the second 30b is meshed with the first rotating shaft 30a, the second rotating shaft 20b is disposed on the second permanent magnet suspension bearing 40b, and a direction of a force acting on the second bevel gear bearing 40b is opposite to a direction of a force acting on the second rotating shaft 20b, and the second rotating shaft 20b is opposite to a direction of a force acting on the second rotating shaft 20 b. Through the wind power generation device 100, wind force acts on the blades 101, the first rotating shaft 20a rotates around the first direction D1, and because the first bevel gear 30a is meshed with the second bevel gear 30b, the second rotating shaft 20b rotates around the second direction D2 along with the rotation of the first rotating shaft 20a, and the second direction D2 is the direction in which the axis of the second rotating shaft 20b is located, so that the second rotating shaft 20b drives the input end of the generator 50 to rotate, thereby realizing the generation of electric energy by the generator 50 and the conversion of wind energy into electric energy.
In addition, according to the wind power generation apparatus 100, the first permanent magnet suspension bearing 40a and the second permanent magnet suspension bearing 40b can be used to reduce the resistance at the time of starting the wind power generation apparatus 100, so that the energy region of low wind speed can be used, and wind energy can be fully utilized. Specifically, the first permanent magnet suspension bearing 40a supports the rotation of the first shaft 20a by using the magnetic force generated by the permanent magnet without a conventional mechanical contact bearing, thereby avoiding resistance due to contact friction with the first shaft 20 a. Similarly, the second permanent magnet suspension bearing 40b supports the rotation of the second rotating shaft 20b using the magnetic force generated by the permanent magnet, without a conventional mechanical contact bearing, thereby avoiding resistance due to contact friction with the second rotating shaft 20 b. When the wind power generation device 100 is started, the first rotating shaft 20a and the second rotating shaft 20b can stably suspend and rotate in a non-contact state, and the non-contact design greatly reduces friction resistance caused by mechanical contact, so that the overall resistance of the wind power generation device 100 at the time of starting is reduced.
It should be noted that, in some embodiments, for example, the rotation direction of the first helical gear 30a is left-handed, the first helical gear 30a has a rightward force component on the first rotating shaft 20a, then the first permanent magnetic suspension bearing 40a is a left-handed permanent magnetic suspension bearing, the first permanent magnetic suspension bearing 40a has a leftward force on the first rotating shaft 20a, so that the force of the first permanent magnetic suspension bearing 40a on the first rotating shaft 20a is opposite to the force of the first helical gear 30a on the first rotating shaft 20a, and thus the force of the first permanent magnetic suspension bearing 40a on the first rotating shaft 20a can be restrained by using the spatial stress of the first helical gear 30a, so as to prevent the potential energy of the first permanent magnetic suspension bearing 40a from being reduced, and improve the suspension stability of the wind power generation apparatus 100 in the first direction D1.
It will be appreciated that in some embodiments, for example, the rotation direction of the first helical gear 30a is right-handed, the first helical gear 30a has a leftward force component on the first shaft 20a, then the first permanent magnetic suspension bearing 40a is a right-handed permanent magnetic suspension bearing, the first permanent magnetic suspension bearing 40a has a rightward force on the first shaft 20a, so that the force of the first permanent magnetic suspension bearing 40a on the first shaft 20a is opposite to the force of the first helical gear 30a on the first shaft 20a, and thus the force of the first permanent magnetic suspension bearing 40a on the first shaft 20a can be restrained by using the spatial force of the first helical gear 30a, so as to prevent the potential energy of the first permanent magnetic suspension bearing 40a from being reduced, and improve the suspension stability of the wind power generation apparatus 100 in the direction in which the first shaft 20a is located (i.e., the first direction D1).
It should be noted that, in some embodiments, when the rotation direction of the first helical gear 30a is left-handed, the second helical gear 30b meshed with the first helical gear 30a is left-handed, the second helical gear 30b has a force component facing away from the second permanent magnetic suspension bearing 40b, for example, an upward force component, on the second rotating shaft 20b, and the second permanent magnetic suspension bearing 40b pushes down the permanent magnetic suspension bearing, and the second permanent magnetic suspension bearing 40b has a downward force on the second rotating shaft 20b, so that the force of the second permanent magnetic suspension bearing 40b on the second rotating shaft 20b is opposite to the force of the second helical gear 30b on the second rotating shaft 20b, so that the space of the second helical gear 30b can be used to force the second permanent magnetic suspension bearing 40b, thereby preventing the potential energy of the second permanent magnetic suspension bearing 40b from being reduced, and improving the stability of the wind power generation device 100 in the second direction D2 in which the axis of the second permanent magnetic suspension bearing 20b is located. That is, the arrangement of the first bevel gear 30a and the second bevel gear 30b improves the suspension stability of the entire wind turbine generator 100.
It will be appreciated that in some embodiments, when the rotation direction of the first helical gear 30a is right-handed, the second helical gear 30b meshed with the first helical gear 30a is right-handed, the second helical gear 30b has a force component facing away from the second permanent magnet suspension bearing 40b, for example, an upward force component, on the second rotating shaft 20b, and the second permanent magnet suspension bearing 40b pushes down the permanent magnet suspension bearing, and the second permanent magnet suspension bearing 40b has a downward force on the second rotating shaft 20b, so that the force of the second permanent magnet suspension bearing 40b on the second rotating shaft 20b is opposite to the force of the second helical gear 30b on the second rotating shaft 20b, so that the force of the second permanent magnet suspension bearing 40b on the second rotating shaft 20b can be restrained by using a spatial force of the second helical gear 30b, thereby preventing the potential energy of the second permanent magnet suspension bearing 40b from being lowered, and improving the suspension stability of the wind power generation apparatus 100 in the direction D2 in which the axis of the second rotating shaft 20b is located. That is, the arrangement of the first bevel gear 30a and the second bevel gear 30b improves the suspension stability of the entire wind turbine generator 100.
It should be noted that, in some embodiments, the number of the blades 101 is plural, and the plurality of the blades 101 are uniformly distributed along the circumferential direction of the first rotation shaft 20 a. By arranging the plurality of blades 101, when wind force acts on the plurality of blades 101, each blade 101 can generate moment, and the moment generated by the plurality of blades 101 can be overlapped, so that the utilization of the wind force is improved, and the power generation efficiency of the generator 50 is improved. Meanwhile, the blades 101 are uniformly distributed along the circumferential direction of the first rotating shaft 20a, so that the uniform action of wind force in all directions can be ensured, the condition that the rotation of the first rotating shaft 20a is unstable due to uneven distribution of the blades 101 is avoided, and the risk of unstable operation of the generator 50 is further reduced. This design not only improves the rotational stability and reliability of the first shaft 20a, but also optimizes the overall performance of the wind power plant 100 so that it can better adapt to complex and varied wind environments.
For the wind wheel structure 10 and the first permanent magnet suspension bearings 40a, in some embodiments, the number of the wind wheel structures 10 is two, the two wind wheel structures 10 are symmetrically disposed at two ends of the first rotating shaft 20a, the number of the first permanent magnet suspension bearings 40a is two, which are used in cooperation with the two wind wheel structures 10, one end of the first rotating shaft 20a is inserted into one of the first permanent magnet suspension bearings 40a, and the other end of the first rotating shaft 20a is inserted into the other one of the first permanent magnet suspension bearings 40a. By symmetrically arranging two wind wheel structures 10, on one hand, the weight distribution of the whole wind power generation device 100 is balanced, the risk of inclination or damage of the wind power generation device 100 caused by gravity center deviation is reduced, and the running stability of the wind power generation device 100 is improved. In addition, the two wind wheel structures 10 can capture wind force at the same time, convert the wind energy into mechanical energy, and transmit the mechanical energy to the generator 50, thereby improving the power generation efficiency. It is also important that the two first permanent magnet suspension bearings 40a support the two ends of the first rotating shaft 20a respectively, so that vibration and noise of the first rotating shaft 20a during high-speed rotation are effectively reduced, and reliability and service life of the wind power generation device 100 as a whole are improved.
It should be noted that, in some embodiments, referring to fig. 3, the wind power generation device 100 further includes a limiting member 3, the limiting member 3 is disposed on the first rotating shaft 20a, and the limiting member 3 is configured to bear the acting forces of the two first permanent magnetic suspension bearings 40a on the first rotating shaft 20 a. For example, the rotation direction of the first bevel gear 30a is left-handed, the first permanent magnetic suspension bearing 40a is a left-handed permanent magnetic suspension bearing, the limiting member 3 is located at one end of the first rotating shaft 20a away from the first permanent magnetic suspension bearing 40a, the limiting member 3 may be a thimble or a locating pin, so that the first bevel gear 30a has a rightward force component on the first rotating shaft 20a, the two first permanent magnetic suspension bearings 40a have leftward forces on the first rotating shaft 20a, and the limiting member 3 carries the forces of the two first permanent magnetic suspension bearings 40a on the first rotating shaft 20 a.
It should be noted that, in some embodiments, referring to fig. 1 and 2, the first permanent magnetic suspension bearing 40a is disposed on a side of the bellows 102 away from the first bevel gear 30a, and the first rotating shaft 20a is inserted into the first permanent magnetic suspension bearing 40a after penetrating through the bellows 102.

In order to facilitate the reader's understanding of the design concept of the wind power generation device 100 provided by the embodiments of the present application, the advantages of the wind power generation device 100 will now be illustrated. Referring to fig. 3, the wind power generation apparatus 100 includes two wind wheel structures (not shown in fig. 3), a first rotating shaft 20a, a first bevel gear 30a, two first permanent magnet suspension bearings 40a, two third permanent magnet suspension bearings 40c, a second rotating shaft 20b, a second bevel gear 30b, two second permanent magnet suspension bearings 40b, a tapered roller bearing 40d, a stopper 3, and a generator (not shown in fig. 3).
The rotation direction of the first helical gear 30a is left-handed, and the rotation direction of the second helical gear 30b is left-handed. The two first permanent magnetic suspension bearings 40a and the two third permanent magnetic suspension bearings 40c are left-push permanent magnetic suspension bearings, and the second permanent magnetic suspension bearing 40b is a push-down permanent magnetic suspension bearing.

Wherein the magnetization directions of the outer rings 40c1 of the two third permanent magnetic suspension bearings 40c are all directed to the left, and the magnetization directions of the inner rings 40c of the two third permanent magnetic suspension bearings 40c are all directed to the right. Along the direction (i.e., the second direction D2/the vertical direction) along which the axis of the second rotating shaft 20b is located, the magnetization directions of the outer rings 40b1 of the two second permanent magnetic suspension bearings 40b are all downward, and the magnetization directions of the inner rings 40b2 of the two second permanent magnetic suspension bearings 40b are all upward.
F l1 in FIG. 3 is the levitation force applied by the first rotating shaft 20a at one of the first permanent magnet levitation bearings 40a, G 1 in FIG. 3 is the gravity applied by the first rotating shaft 20a, F d1 in FIG. 3 is the force applied by the first helical gear 30a applied by the first rotating shaft 20a, the direction of F d1 is right due to the left-hand rotation of the first helical gear 30a, F p1 in FIG. 3 is the force applied by one of the first permanent magnet levitation bearings 40a applied by the first rotating shaft 20a, and the direction of F p1 is left due to the opposite direction of the force applied by the first permanent magnet levitation bearing 40a to the first rotating shaft 20a from the force applied by the first helical gear 30a to the first rotating shaft 20 a. F l2 in FIG. 3 is the levitation force exerted by the first rotating shaft 20a at one of the third permanent magnet levitation bearings 40c, F p2 in FIG. 3 is the force exerted by one of the third permanent magnet levitation bearings 40c exerted by the first rotating shaft 20a, and F p2 is left because the direction of the force exerted by the third permanent magnet levitation bearing 40c on the first rotating shaft 20a is opposite to the direction of the force exerted by the first bevel gear 30a on the first rotating shaft 20 a. F l3 in FIG. 3 is the levitation force exerted by the first rotating shaft 20a at the other one of the third permanent magnet levitation bearings 40c, F p3 in FIG. 3 is the force exerted by the other one of the first permanent magnet levitation bearings 40a exerted by the first rotating shaft 20a, and F p3 is left-hand because the direction of the force exerted by the first permanent magnet levitation bearing 40a on the first rotating shaft 20a is opposite to the direction of the force exerted by the first bevel gear 30a on the first rotating shaft 20 a. F l4 in FIG. 3 is the levitation force exerted by the first rotating shaft 20a at the other one of the first permanent magnet levitation bearings 40a, F p4 in FIG. 3 is the force exerted by the other one of the first permanent magnet levitation bearings 40a exerted by the first rotating shaft 20a, and F p4 is left-hand because the direction of the force exerted by the first permanent magnet levitation bearing 40a on the first rotating shaft 20a is opposite to the direction of the force exerted by the first bevel gear 30a on the first rotating shaft 20 a.
According to the enshao theorem, there are both maxima and minima of potential energy. According to the first rotation axis 20a shown in fig. 3, it is decomposed in the cartesian coordinate system, assuming that the second direction D2 facing upward is the y direction, assuming that the first direction D1 facing rightward is the z direction, and assuming that the direction perpendicular to the paper surface and facing outward from the paper surface is the x direction, there is a potential energy minimum value in the x direction, there is no potential energy maximum and minimum value in the z direction, and there is a potential energy maximum value in the z direction, namely:
thus, if the structure is made stable, it is necessary to add mechanical constraints in the z-direction, namely:
Referring to fig. 4, the horizontal axis in fig. 4 is the z direction, and U M in the vertical axis represents potential energy. When mechanical constraint is added in the z direction, for example, the first helical gear 30a provided by the embodiment of the application is stressed in space, the acting force of the first permanent magnet suspension bearing 40a and the third permanent magnet suspension bearing 40c on the first rotating shaft 20a can be constrained, so that the potential energy of the first permanent magnet suspension bearing 40a and the third permanent magnet suspension bearing 40c is prevented from being reduced, and the suspension stability of the wind power generation device 100 in the first direction D1 is improved.
In fig. 3, G 2 is the gravity applied to the second rotating shaft 20b, F d2 in fig. 3 is the force applied to the second bevel gear 30b applied to the second rotating shaft 20b, because the rotation direction of the second bevel gear 30b is left-handed, the direction of F d2 is upward, and F p5 in fig. 3 is the force applied to one of the second permanent magnet suspension bearings 40b applied to the second rotating shaft 20b, because the force applied to the second rotating shaft 20b by the second permanent magnet suspension bearing 40b is opposite to the force applied to the second rotating shaft 20b by the second bevel gear 30b, the direction of F p5 is downward. In fig. 3, F p6 is the force applied by one of the second permanent magnetic suspension bearings 40b to which the second rotating shaft 20b is subjected, and since the direction of the force applied by the second permanent magnetic suspension bearing 40b to the second rotating shaft 20b is opposite to the direction of the force applied by the second bevel gear 30b to the second rotating shaft 20b, the direction of F p6 is downward when the second permanent magnetic suspension bearing 40b pushes down the permanent magnetic suspension bearing.
According to the second shaft 20b shown in fig. 3, when it is decomposed in a cartesian coordinate system, there is a potential energy minimum in the x-direction, the z-direction, the displacement and the rotation, and there is no potential energy maximum and minimum in the y-direction, but there is a potential energy maximum in the y-direction, namely:
thus, if the structure is made stable, mechanical constraints need to be added in the y-direction. When a mechanical constraint is added in the y direction, for example, the second helical gear 30b provided in the embodiment of the present application is spatially stressed, the acting force of the second permanent magnetic suspension bearing 40b on the second rotating shaft 20b may be constrained, so as to prevent the potential energy of the second permanent magnetic suspension bearing 40b from being reduced, and improve the suspension stability of the wind power generation device 100 in the second direction D2. That is, the arrangement of the first bevel gear 30a and the second bevel gear 30b improves the suspension stability of the entire wind turbine generator 100.
It should be noted that the point contact of the bevel gears is a key to ensure the decoupling of the two formulas, i.e. the rotational potential energy component of the first shaft 20a in the x direction will not form a countermeasure against the rotational potential energy component of the second shaft 20b in the x direction, thereby causing instability.
