Description

Technical Field

[0001] The utility model relates to the technical field of power generation, in particular to a magnetic energy power generation device. Background Art

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that are mutually electromagnetically inductive, so as to generate electromagnetic power and achieve the purpose of energy conversion.

[0003] Generators are usually composed of components such as stators, rotors, end covers and bearings. The stator consists of a stator core, a coil winding, a base and other structural parts that fix these parts. The rotor consists of a shaft, a rotor core (or a pole, a yoke) winding, a guard ring, a center ring, a slip ring, a fan and a shaft. Wind turbines include horizontal-axis wind turbines and vertical-axis wind turbines, among which the rotors of vertical-axis wind turbines are arranged in a vertical or nearly vertical direction, and the cross-section of the blades is crank-shaped or geometrically deformed. Compared with horizontal-axis wind turbines, the rotation direction of vertical-axis wind turbines is not affected by changes in wind direction, has better adaptability and stability, and does not require a direction tracking device. The advantages of vertical-axis wind turbines also include miniaturization, lightness, and high reliability, but the efficiency is slightly lower than that of horizontal-axis wind turbines when the torque output is fully communicated.

[0004] Mechanical wear is one of the most common types of wear in wind turbines, mainly due to the friction between mechanical parts. Mechanical wear in wind turbines mainly includes bearing wear, gear wear, and connector wear. In order to prevent further mechanical wear, it is necessary to regularly replace wear parts, strengthen lubrication, and pay attention to mechanical matching accuracy to ensure that the friction between mechanical parts is small. The rotor bearings are basically in non-stop load operation, which causes the bearings to wear faster. Therefore, there is an urgent need for a power generation device that can slow down the wear of the rotor bearings. Utility Model Content

[0005] The utility model aims to provide a magnetic energy power generation device to improve the problem of rapid wear of the bearing of the rotor in the generator.

[0006] The utility model is realized by the following technical solutions:

[0007] A magnetic energy power generation device comprises a stator and a rotor, and also comprises a vertically arranged cylinder, wherein the stator is mounted on the inner wall of the cylinder, a bottom plate is arranged at the bottom of the cylinder, a bottom plane bearing is arranged at the middle of the upper surface of the bottom plate, a loose ring of the bottom plane bearing is arranged on the bottom plate, and a tight ring of the bottom plane bearing is located above the loose ring, the rotor is located at the inner ring of the stator, the bottom end of the rotor shaft passes through the tight ring of the bottom plane bearing and is tightly matched with the tight ring, a first magnet is arranged on the upper surface of the bottom plate, a second magnet is arranged at the lower end of the rotor shaft, the second magnet is located directly above the first magnet and repels the first magnet, a top plate is arranged above the cylinder, a notch is opened on the top plate, a top plane bearing is arranged at the notch of the top plate, the loose ring of the top plane bearing is arranged on the top plate, the tight ring of the top plane bearing is located below the loose ring, the top end of the rotor shaft passes through the tight ring of the top plane bearing and is tightly matched with the tight ring, the top end of the rotor shaft passes through the top plane bearing and the notch and extends to the top of the cylinder; the tight ring of the bottom plane bearing can be offset in the vertical direction.

[0008] Furthermore, a plurality of first magnets with the same magnetic pole direction are arranged on the upper surface of the base plate along the circumference of the bottom plane bearing, and a plurality of second magnets with the same magnetic pole direction are arranged on the lower end of the rotor shaft along the circumference of the shaft, and the plurality of second magnets are located directly above the plurality of first magnets and repel the plurality of first magnets.

[0009] Furthermore, a mounting tube is provided at the notch of the outer top wall of the top plate, the top end of the rotating shaft of the rotor extends to the top of the mounting tube through the inner ring of the mounting tube, and the interior of the mounting tube is filled with a dustproof layer.

[0010] Furthermore, the interior of the installation tube is filled with a hygroscopic layer, and the hygroscopic layer is located below the dustproof layer.

[0011] Furthermore, a sealing plate is arranged above the mounting cylinder, and a through hole is opened on the sealing plate for the rotating shaft of the rotor to pass through.

[0012] Furthermore, a protective cover is provided at one end of the rotating shaft of the rotor passing through the sealing plate, and the protective cover is used to cover the mounting cylinder.

[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0014] In the utility model, the rotor is vertically arranged in the cylinder, the bottom of the rotor shaft is connected to the bottom plate through a plane bearing, and a hood and other structures are arranged at one end of the rotor located outside the cylinder. The rotation of the hood drives the rotor to rotate in the cylinder, and the rotor drives the magnet thereon to rotate relative to the coil of the stator, so that the coil of the stator cuts the magnetic flux lines, and the wire led out of the coil is used to transmit electric energy. Since the first magnet on the bottom plate and the second magnet on the rotor shaft repel each other, that is, the first magnet exerts an upward repulsive force on the second magnet, and the first magnet is not in contact with the second magnet, this can weaken a part of the pressure exerted by the rotor on the bottom plane bearing, thereby reducing the load exerted by the rotor on the bottom plane bearing during rotation. The bottom plane bearing and the top plane bearing can reduce the wear of the bottom plane bearing to a certain extent while ensuring that the rotor can rotate normally in the cylinder, which is beneficial to extending the service life of the bottom plane bearing.

[0023] Example 1

[0024] A magnetic energy generating device, referring to Figure 1 , Figure 2 , including a stator 1 and a rotor 2, and also including a vertically arranged cylinder 3, the stator 1 is installed on the inner wall of the cylinder 3, a bottom plate 4 is arranged at the bottom of the cylinder 3, a bottom plane bearing 5 is arranged in the middle of the upper surface of the bottom plate 4, a loose ring of the bottom plane bearing 5 is arranged on the bottom plate 4, a tight ring of the bottom plane bearing 5 is located above the loose ring, the rotor 2 is located at the inner ring of the stator 1, the bottom end of the rotating shaft of the rotor 2 passes through the tight ring of the bottom plane bearing 5 and is tightly matched with the tight ring, a first magnet 6 is arranged on the upper surface of the bottom plate 4, a second magnet 7 is arranged at the lower end of the rotating shaft of the rotor 2, the second magnet 7 is located directly above the first magnet 6 and repels the first magnet 6, combined with Figure 3 , a top plate 8 is arranged above the cylinder 3, a notch 9 is provided on the top plate 8, a top plane bearing 10 is arranged at the notch 9 of the top plate 8, a loose ring of the top plane bearing 10 is arranged on the top plate 8, a tight ring of the top plane bearing 10 is located below the loose ring, the top end of the rotating shaft of the rotor 2 passes through the tight ring of the top plane bearing 10 and is tightly matched with the tight ring, and the top end of the rotating shaft of the rotor 2 passes through the top plane bearing 10 and the notch 9 and extends to the top of the cylinder 3; the tight ring of the bottom plane bearing 5 can be offset in the vertical direction, and the offset here means that the rotating shaft of the rotor 2 has a small amount of margin for movement in the vertical direction, and when the rotor 2 moves up and down, both plane bearings can operate normally, that is, rolling friction can occur between the tight ring and the loose ring of the plane bearing through the ball. The bottom plane bearing 5 and the top plane bearing 10 are preferably ball-type plane bearings, and the plane bearing includes a loose ring, a tight ring, and a ball located between the loose ring and the tight ring; the loose ring refers to a ring that is not in direct contact with the rotating shaft, and the tight ring refers to a ring that is directly tightly matched with the rotating shaft.

[0025] The rotor 2 is vertically arranged in the cylinder 3, and the bottom of the rotating shaft of the rotor 2 is connected to the bottom plate 4 through a plane bearing. A hood and other structures are arranged at one end of the rotor 2 located outside the cylinder 3. The rotation of the hood drives the rotor 2 to rotate in the cylinder 3, and the rotor 2 drives the magnet thereon to rotate relative to the coil of the stator 1, so that the coil on the stator 1 cuts the magnetic flux lines, and the wires led out of the coils are used to transmit electric energy. Since the first magnet 6 on the bottom plate 4 and the second magnet 7 on the rotating shaft of the rotor 2 repel each other, that is, the first magnet 6 applies an upward repulsive force to the second magnet 7, and the first magnet 6 does not contact the second magnet 7, this can weaken a part of the pressure applied by the rotor 2 to the bottom plane bearing 5, thereby reducing the load applied by the rotor 2 to the bottom plane bearing 5 during rotation. The bottom plane bearing 5 and the top plane bearing 10 can reduce the wear of the bottom plane bearing 5 to a certain extent while ensuring that the rotor 2 can rotate normally in the cylinder 3, which is beneficial to extending the service life of the bottom plane bearing 5. The top plane bearing 10 cooperates with the bottom plane bearing 5 to make the rotor 2 rotate in the cylinder 3, and on the other hand, the top plane bearing 10 can limit the rotor 2 on the cylinder 3. The bottom plane bearing 5 bears the main gravity of the rotor 2, while the top plane bearing 10 bears almost no gravity of the rotor 2, but bears a little lateral pressure applied when the rotor 2 has a tendency to tilt and deviate.

The use of a plurality of first magnets 6 and a plurality of second magnets 7 can, on the one hand, increase the upward repulsive force on the rotor 2, thereby reducing the pressure exerted by the rotor 2 on the bottom plane bearing 5, and on the other hand, can make the repulsive force on the rotor 2 in all directions the same, and can reduce the tendency of the rotor 2 to tilt and deviate.

[0027] As a preferred embodiment, refer to Figure 1 , Figure 3 A mounting tube 11 is provided at the notch 9 of the outer top wall of the top plate 8, and the top end of the rotating shaft of the rotor 2 extends to the top of the mounting tube 11 through the inner ring of the mounting tube 11, and the inside of the mounting tube 11 is filled with a dustproof layer 12. The dustproof layer 12 can be made of dustproof cotton and other materials to reduce the situation where dust enters the cylinder body 3.

[0028] As a preferred embodiment, refer to Figure 1 , Figure 3The interior of the mounting tube 11 is filled with a hygroscopic layer 13 , which is located below the dustproof layer 12 . The hygroscopic layer 13 may be made of a hygroscopic polymer material, etc., which may improve the watertightness of the tube body 3 .

[0029] As a preferred embodiment, refer to Figure 1 , Figure 3 A sealing plate 14 is arranged above the mounting tube 11 , and a through hole 15 is opened on the sealing plate 14 for the rotating shaft of the rotor 2 to pass through.
