Technical Field
The invention relates to the technical field of motors, in particular to a positive and negative rotation double-rotor energy collector.
Background
Generally, a generator is composed of a stator, a rotor, an end cover, a base, a bearing and the like. The stator and the rotor of the generator are connected and assembled through the bearing, the base and the end cover, so that the rotor can rotate in the stator, a certain exciting current is introduced through the slip ring, the rotor becomes a rotating magnetic field, the stator coil performs the motion of cutting magnetic lines of force, an induced potential is generated, the induced potential is led out through the wiring terminal and is connected in a loop, and then current is generated.
Specifically, the amount of electric power generated by cutting the magnetic field lines is proportional to the relative rotational speed formed between the rotor and the stator, and the larger the relative rotational speed is, the larger the generated electric power amount is. However, in the field of low-speed power generation, although it is possible to increase the relative rotational speed of the stator and the rotor by rotating both of them in the opposite directions, at least one of the following problems occurs in the related art: only the rotor and the stator rotate in the same speed and opposite directions, and the power generation efficiency of the generator in the low-speed power generation field is not further improved, so that the collection efficiency of generated energy in the power generation process is reduced.
Disclosure of Invention
The invention solves the problem that the rotor and the stator only rotate in the same speed and opposite directions, and the power generation efficiency of the generator in the low-speed power generation field is not further improved, so that the collection efficiency of generated energy in the power generation process is reduced.
In order to solve the above problems, the present invention provides a positive and negative rotation dual-rotor energy harvester, comprising: the first rotor is internally provided with a first accommodating space; the second rotor is arranged coaxially with the first rotor, and the second rotor is internally arranged in the first accommodating space; the multi-stage transmission assembly is in transmission connection with the first rotor and the second rotor; and when the first rotor rotates in a first direction at a first rotational speed, the second rotor is caused to rotate in a second direction opposite to the first direction at a second rotational speed by the multi-stage transmission assembly; the first speed is n1, the second speed is n2, n2 is k × n1, k is a speed coefficient, and k is greater than 1 or 0 is less than 1.
Compared with the prior art, the technical scheme has the following technical effects: on the basis of the related technical scheme, the technical scheme replaces single-stage transmission of bevel gears by the multi-stage transmission assembly, so that the rotating speed of the first rotor is not equal to that of the second rotor by means of the action of the multi-stage transmission assembly, namely the relative rotating speed of the first rotor and the second rotor is greater than 2 times of the minimum rotating speed of the first rotor or the second rotor. Specifically, in a specific embodiment, k may be 2, and n2 is 2n1, that is, the rotation speed of the second rotor is 2 times the rotation speed of the first rotor, and since the first rotor and the second rotor rotate in opposite directions, the relative rotation speed of the first rotor and the second rotor is 3n1, that is, the relative rotation speed of the first rotor is 3 times the rotation speed of the first rotor. Therefore, on the premise of ensuring that the rotating speed of the first rotor is unchanged, the speed of the forward and reverse rotation dual-rotor energy collector for cutting the magnetic field is increased by two times, and even compared with a generator with a stator and a rotor rotating in equal and opposite directions, the speed of the cutting magnetic field is improved, the power generation efficiency is further improved in the field of low-speed power generation, and the energy collecting efficiency is improved.
In one example of the present invention, the first rotor includes: a first mounting housing; the second mounting shell is arranged in the axis position of the first mounting shell, and a magnetic field mounting position is formed between the first mounting shell and the second mounting shell; the magnetic assembly is arranged at the magnetic field installation position; the second rotor is clamped between the first mounting shell and the second mounting shell, and cuts magnetic field lines formed by the magnetic assembly when the first rotor and the second rotor move.
Compared with the prior art, the technical scheme has the following technical effects: because the magnetic assembly is arranged on the first rotor, along with the rotation of the first rotor, in the process that the second rotor and the first rotor relatively rotate, the magnetic field lines of the electromagnetic field formed by the magnetic assembly are cut by the second rotor, so that induced current is more stable. Specifically speaking, avoided locating magnetic field respectively on first rotor and second rotor, and lead to when the relative motion between first rotor and the second rotor is unstable, easily make magnetic field be in unstable state, and then reduced the efficiency that the cutting magnetic field line generated the induced electricity. For example, when one of the first rotor and the second rotor is in a stop state, the cutting magnetic induction line motion can be performed only when the first rotor and the second rotor are in a state that the magnetic assemblies are paired to form a magnetic field. And in this technical scheme, can make first installation casing and second installation casing be integrated into one piece to can make behind the installation magnetic component, ensure the stability that magnetic component formed the electromagnetic field. Therefore, whether only the first rotor rotates or only the second rotor rotates, the magnetic field lines can be cut without interruption, electric quantity can be generated without interruption, and power generation efficiency is greatly improved.
In one example of the invention, the magnetic assembly comprises a first magnetic assembly and a second magnetic piece, wherein the first magnetic assembly is arranged on one side of the first mounting shell close to the second mounting shell; the second magnetic part is arranged on one side, close to the first mounting shell, of the second mounting shell, and the first magnetic assembly and the second magnetic part are opposite in attraction; the second rotor is provided with a conductive coil clamped between the first magnetic assembly and the second magnetic member.
Compared with the prior art, the technical scheme has the following technical effects: the magnetic field formed by the combination of the first magnetic component and the second magnetic part is simple in structure, and the magnetic component can be taken as the detachable installation to the first rotor by combining specific practical conditions, so that the replacement of the magnetic component is facilitated.
In one example of the invention, one side of the first mounting shell, which is close to the second mounting shell, is provided with m1 first mounting positions, the m1 first mounting positions are arranged around the axis at equal intervals, and the first mounting positions are arranged in a matching way with the first magnetic assembly; one side of the second mounting shell, which is close to the first mounting shell, is provided with m2 second mounting positions, the m2 second mounting positions are arranged around the axis at equal intervals, and the second mounting positions are arranged in a matching manner with the second magnetic piece; wherein m1 and m2 are both constants greater than 0.
Compared with the prior art, the technical scheme has the following technical effects: in a specific example, m1 may be 8, for example, so that the number of the first mounting positions is 8, and since m1 first mounting positions are equally spaced from each other, the first magnetic components mounted in cooperation therewith are also equally spaced from each other. In contrast, m2 is 4, for example, so that the number of the second magnetic members connected with the second mounting position is 4. It will be appreciated that the diameter of the first mounting housing is greater than the diameter of the second mounting housing such that the circumferential diameter enclosed by m2 second mounting locations is less than the circumferential diameter enclosed by m1 first mounting locations. Therefore, in order to ensure that the first rotor and the second rotor are in a state of cutting magnetic field lines at all times to generate induced current in the process of mutual movement, the number of the first mounting positions is more than that of the second mounting positions, so that the magnetic lines diverged by the second magnetic part can be received by the first magnetic assembly as much as possible, and the situation that the generation of current discontinuously is avoided to reduce the overall power generation efficiency in the limited first accommodating space is ensured; in addition, through the equidistant setting respectively with first installation position and second installation position, can make first rotor be in stable state at rotatory in-process, avoid making and adorn a plurality of first magnetic component and second magnetic part after, lead to first rotor to appear rocking because eccentric settings makes rotatory in-process be unfavorable for the positive and negative rotation birotor energy collector of steady operation to generate electricity, easily cause the risk of toppling.
In one example of the present invention, the first magnetic component includes: the third magnetic part is arranged opposite to the corresponding second magnetic part, and the third magnetic part and the corresponding second magnetic part are mutually parallel and attract each other in opposite directions; at least one fourth magnetic piece, which is arranged adjacent to the third magnetic piece, is obliquely arranged relative to the second magnetic piece, and is opposite to the second magnetic piece in attraction; and the included angle formed by the side surfaces of the at least one fourth magnetic part and the second magnetic part, which are close to each other, is alpha.
Compared with the prior art, the technical scheme has the following technical effects: a may be 45 ° in order to make the effective magnetic field formed between the first magnetic assembly and the corresponding second magnetic member as large as possible, so as to achieve effective continuity with the adjacent magnetic field, i.e., so that the magnetic field formed inside the first rotor is continuously arranged around the rotation axis, thereby ensuring the overall power generation efficiency of the motor.
In one example of the present invention, the number of the second magnetic members is plural, and at least one side of the second magnetic member near the axis is an N pole, and at least one side of the second magnetic member adjacent to the N pole near the axis is an S pole.
Compared with the prior art, the technical scheme has the following technical effects: the second magnetic parts which are adjacently arranged are arranged for the same magnetism, so that the magnetism of the second magnetic parts is mutually offset, the overall magnetic field intensity of the motor is weakened, and the power generation efficiency is reduced.
In one example of the present invention, the surface of the second rotor is provided with a plurality of mounting grooves for mounting the conductive coil, and the mounting grooves are arranged at equal intervals.
Compared with the prior art, the technical scheme has the following technical effects: it is possible to ensure stable rotation of the second rotor and stable and uniform delivery of the current generated by cutting the magnetic field lines.
In one example of the invention, the number of the conductive coils is multiple, and the conductive coils are arranged in one-to-one correspondence with the mounting grooves; the conductive coils are connected in series and/or in parallel.
Compared with the prior art, the technical scheme has the following technical effects: the conductive coils can be arranged in series with each other, so that a larger voltage is output; accordingly, the conductive coils can be arranged in parallel with each other, so that a larger current is output. Thus, to meet different practical requirements.
In one example of the present invention, the multistage transmission assembly includes: the bracket assembly is arranged close to the first end of the second rotor; the first input shaft assembly is arranged on the bracket assembly and is rotationally connected with the second rotor; a first gear assembly connected to the first input shaft assembly; the at least two second output shaft assemblies are arranged on the bracket assembly; and the second gear assembly is connected to the second output shaft assembly, is meshed with the first gear assembly and is in transmission connection with the first rotor.
Compared with the prior art, the technical scheme has the following technical effects: the multi-stage transmission assembly is simple in structure and convenient to replace.
In an example of the invention, the bracket assembly is provided with a first supporting seat and a second supporting seat which are oppositely arranged, one end of the first input shaft assembly is rotationally connected with the first supporting seat far away from the second rotor, and the other end of the first input shaft assembly is rotationally connected with the second rotor; the second support seat is provided with a mounting hole for the first input shaft assembly to pass through; the second gear assembly includes: the first second transmission gear is arranged on any one of the at least two second output shaft assemblies and meshed with the first transmission gear of the first gear assembly; the second transmission gear assembly III is in transmission connection with the first rotor through a connecting piece arranged in the mounting hole; and the second transmission gear assembly II is arranged on the other one of the at least two second output shaft assemblies, and is meshed with the second transmission gear assembly III.
Compared with the prior art, the technical scheme has the following technical effects: the multistage transmission assembly is simple in structure and convenient to replace, and under the condition that the overall size of the forward and reverse rotation dual-rotor energy collector is ensured, the mounting space formed by the support assembly is fully utilized, and the power generation efficiency is effectively increased.
After the technical scheme of the invention is adopted, the following technical effects can be achieved:
(1) when k is 2, n2 is 2n1, that is, the rotation speed of the second rotor is 2 times the rotation speed of the first rotor, and since the first rotor and the second rotor rotate in opposite directions, the relative rotation speed of the first rotor and the second rotor is 3n1, that is, the relative rotation speed of the first rotor is 3 times the rotation speed of the first rotor. Therefore, on the premise of ensuring that the rotating speed of the first rotor is not changed, the speed of the forward and reverse rotating dual-rotor energy collector for cutting the magnetic field is increased by two times, even compared with a generator with a stator and a rotor rotating in the same reverse direction, the speed of cutting the magnetic field is increased, and the generating efficiency is further improved in the field of low-speed power generation;
(2) the magnetic field is prevented from being respectively arranged on the first rotor and the second rotor, so that the magnetic field is easily in an unstable state when the relative motion between the first rotor and the second rotor is unstable, and the efficiency of cutting the magnetic field lines to generate induced electricity is reduced. For example, when one of the first rotor and the second rotor is in a stop state, the cutting magnetic induction line motion can be performed only when the first rotor and the second rotor are in a state that the magnetic assemblies are paired to form a magnetic field. And in this technical scheme, can make first installation casing and second installation casing be integrated into one piece to can make behind the installation magnetic component, ensure the stability that magnetic component formed the electromagnetic field. Therefore, whether only the first rotor rotates or only the second rotor rotates, the magnetic field lines can be cut without interruption, uninterrupted power generation is realized, and the power generation efficiency is greatly improved;
(3) the number of the first mounting positions is larger than that of the second mounting positions, so that the magnetic wires diverged by the second magnetic elements can be received by the first magnetic assemblies as much as possible, and the situation that current is generated discontinuously to reduce the overall power generation efficiency in a limited first accommodating space is avoided; in addition, through the equidistant setting respectively with first installation position and second installation position, can make first rotor be in stable state at rotatory in-process, avoid making and adorn a plurality of first magnetic component and second magnetic part after, lead to first rotor to appear rocking because eccentric settings makes rotatory in-process be unfavorable for the positive and negative rotation birotor energy collector of steady operation to generate electricity, easily cause the risk of toppling.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The first embodiment is as follows:
referring to fig. 1, a schematic structural diagram of a forward/reverse rotation dual-rotor energy harvester 100 according to an embodiment of the present invention is shown. Referring to fig. 2-5, a counter-rotating dual rotor energy harvester 100, for example, includes a first rotor 10, a second rotor 20, and a multi-stage drive assembly 30. A first accommodating space 11 is arranged in the first rotor 10; the second rotor 20 is arranged coaxially with the first rotor 10, and the first accommodating space 11 is arranged in the second rotor 20; the multi-stage transmission assembly 30 is in transmission connection with the first rotor 10 and the second rotor 20, and when the first rotor 10 rotates in a first direction at a first rotation speed, the second rotor 20 rotates in a second direction opposite to the first direction at a second rotation speed through the multi-stage transmission assembly 30; the first speed is n1, the second speed is n2, n2 is k × n1, k is a speed coefficient, and k is greater than 1 or 0 is less than 1.
For example, a common generator is designed by a transmission of a bevel gear assembly to rotate a stator of the generator, specifically, the stator is rotated in a direction opposite to that of a rotor, so that the relative rotation speed of the stator and the rotor is increased, and the rate of cutting magnetic field lines is increased, so that the generated electric quantity is increased. However, it is difficult to further increase the power generation amount of the generator, that is, to realize a relative rotational speed of the stator and the rotor of more than 2 times.
Therefore, on the basis of the related art, the present technical solution replaces the single-stage transmission of the bevel gear by the multi-stage transmission assembly 30, so that the rotational speed of the first rotor 10 is not equal to the rotational speed of the second rotor 20 by the multi-stage transmission assembly 30, that is, the relative rotational speed of the first rotor 10 and the second rotor 20 is greater than 2 times the minimum rotational speed of the first rotor 10 or the second rotor 20. Specifically, in a specific embodiment, k may be 2, and n2 is 2n1, that is, the rotation speed of the second rotor 20 is 2 times the rotation speed of the first rotor 10, and since the first rotor 10 and the second rotor 20 rotate in opposite directions, the relative rotation speed of the first rotor 10 and the second rotor 20 is 3n1, that is, the relative rotation speed of the first rotor 10 is 3 times the rotation speed of the second rotor 10. Therefore, on the premise of ensuring that the rotating speed of the first rotor 10 is not changed, the speed of the forward and reverse rotation dual-rotor energy collector 100 for cutting the magnetic field is increased by two times, even compared with a generator with a stator and a rotor rotating in the same reverse direction, the speed of the cutting magnetic field is increased, and the generating efficiency is further improved in the field of low-speed power generation.
Preferably, the first rotor 10 includes, for example, a first mounting case 12, a second mounting case 13, and a magnetic assembly 14. The second mounting shell 13 is internally arranged at the axial position of the first mounting shell 12, and a magnetic field mounting position is formed between the first mounting shell 12 and the second mounting shell 13; the magnetic component 14 is arranged at the magnetic field installation position; the second rotor 20 is interposed between the first mounting case 12 and the second mounting case 13, and cuts magnetic field lines formed by the magnetic assembly 14 when the first rotor 10 and the second rotor 20 move.
Specifically, since the magnetic assembly 14 is disposed on the first rotor 10, the magnetic field lines of the electromagnetic field formed by the magnetic assembly 14 are cut by the second rotor 20 during the relative rotation between the second rotor 20 and the first rotor 10 with the rotation of the first rotor 10, so that the induced current is more stable. Specifically, the situation that the magnetic fields are respectively arranged on the first rotor 10 and the second rotor 20, and when the relative motion between the first rotor 10 and the second rotor 20 is unstable, the magnetic fields are easily in an unstable state, and the efficiency of cutting the magnetic field lines to generate induced electricity is reduced is avoided. For example, when one of the first rotor 10 and the second rotor 20 is in a stop state, the magnetic induction line cutting motion can be performed only when the first rotor 10 and the second rotor 20 are in a state that the magnetic assemblies 14 are paired to form a magnetic field. In the present technical solution, the first mounting housing 12 and the second mounting housing 13 can be integrally formed, so that after the magnetic component 14 is mounted, the stability of the magnetic component 14 forming the electromagnetic field can be ensured. Therefore, the magnetic field lines can be cut without interruption no matter whether only the first rotor 10 rotates or only the second rotor 20 rotates, so that the electric power can be generated without interruption, and the power generation efficiency is greatly improved.
Preferably, the magnetic assembly 14 includes, for example, a first magnetic assembly 141 and a second magnetic member 142, the first magnetic assembly 141 is disposed on a side of the first mounting housing 12 close to the second mounting housing 13; the second magnetic member 142 is disposed on one side of the second mounting housing 13 close to the first mounting housing 12, and the first magnetic assembly 141 and the second magnetic member 142 are opposite in attraction; the second rotor 20 is provided with a conductive coil 22 sandwiched between the first magnetic assembly 141 and the second magnetic member 142.
For example, when the first rotor 10 and the second rotor 20 rotate relatively, the second rotation cuts the magnetic induction lines of the magnetic field formed by the magnetic assembly 14, so as to generate an induced current, and then the induced current is transmitted through the conductive coil 22.
Of course, the magnetic assembly 14 may be, for example, a magnet or an energized electromagnet.
Preferably, m1 first mounting positions are arranged on one side of the first mounting shell 12 close to the second mounting shell 13, m1 first mounting positions are arranged around the axis of the first mounting shell 12 at equal intervals, and the first mounting positions are arranged in a matching way with the first magnetic assembly 141; one side of the second installation shell 13 close to the first installation shell 12 is provided with m2 second installation positions, m2 second installation positions are arranged around the axis of the first installation shell 12 at equal intervals, and the second installation positions are arranged in a matching way with the second magnetic piece 142; wherein m1 and m2 are both constants greater than 0.
In a specific example, m1 may be 8, for example, so that the number of the first mounting positions is 8, and since m1 first mounting positions are equally spaced from each other, the first magnetic assemblies 141 mounted in cooperation therewith are also equally spaced from each other. In contrast, m2 is 4, for example, so that the number of the second magnetic members 142 connected to the second mounting locations is 4. It will be appreciated that the diameter of the first mounting housing 12 is greater than the diameter of the second mounting housing 13, such that the circumferential diameter enclosed by the m2 second mounting locations is less than the circumferential diameter enclosed by the m1 first mounting locations. Accordingly, in order to ensure that the first rotor 10 and the second rotor 20 are all at the time to cut the magnetic field lines to generate induced current during the mutual movement, the first mounting positions are arranged more than the second mounting positions, so as to ensure that the magnetic lines diverged by the second magnetic member 142 can be received by the first magnetic assembly 141 as much as possible, thereby ensuring that the generation of current intermittently in the limited first accommodating space 11 is avoided to reduce the overall power generation efficiency; in addition, through the equidistant setting respectively with first installation position and second installation position, can make first rotor 10 be in stable state at rotatory in-process, avoid making and adorn a plurality of first magnetic component 141 and second magnetic part 142 after, lead to first rotor 10 to appear rocking because eccentric settings and be unfavorable for the positive and negative rotation birotor energy harvester 100 of steady operation to generate electricity, easily cause the risk of toppling.
Preferably, the first magnetic assembly 141 comprises, for example, a third magnetic element and at least one fourth magnetic element. The third magnetic member is opposite to the corresponding second magnetic member 142, and the third magnetic member and the corresponding second magnetic member are parallel to each other and attract each other in opposite directions; at least one fourth magnetic piece is arranged adjacent to the third magnetic piece, the fourth magnetic piece is obliquely arranged relative to the second magnetic piece 142, and the fourth magnetic piece and the second magnetic piece 142 are opposite in attraction; an included angle α is formed between the side surfaces of the at least one fourth magnetic member and the second magnetic member 142, which are close to each other.
On the basis of the above specific example, it can be understood that the value of α is related to the arrangement positions between the plurality of fourth magnetic members and the second magnetic member 142, and when the shapes and the sizes of the fourth magnetic members and the second magnetic member 142 are the same, when the number of the fourth magnetic members is larger, the value range of α formed between the plurality of fourth magnetic members and the same second magnetic member 142 is larger, for example, the angle is changed from 45 ° < α < 90 ° to 20 ° < α < 90 °, and meanwhile, it can be understood that, as α is reduced, the distance between the plurality of adjacent fourth magnetic members is reduced, that is, the magnetic field lines formed by the magnetic assemblies 14 are arranged more uniformly, so that the induced current generated by cutting the magnetic field lines is increased, so that the collected energy is more, and the energy collection efficiency is improved.
