Description

磁悬浮自调桨距垂直轴风力发电机 Maglev self-adjusting vertical axis wind turbine pitch

技术领域 FIELD

本实用新型涉及一种风力发电机,尤其涉及一种磁悬浮自调桨距垂直轴风力发电机。 The present invention relates to a wind power generator, more particularly to a self-adjusting pitch maglev vertical axis wind turbine. 背景技术 Background technique

风力发电机按旋转轴的方向来分,可分为水平轴和垂直轴两种。 Wind turbine according to the direction of the rotation shaft can be divided into two kinds of horizontal and vertical axes. 水平轴风力发电机是在飞机螺旋桨理论上发展成熟起来的,目前被广泛应用。 The horizontal axis wind turbine propeller airplane is in theory the development of mature, is currently widely used. 但是水平轴风力发电机的设计制造都很复杂,具有:l.叶轮占据空间和占地面积大;2.对风塔要求较高;3.叶轮受风不均匀等缺 However, the design and manufacture of a horizontal axis wind turbine is very complex, having:... L occupies a large space and wheel covers; two pairs demanding wind tower; 3 unevenness by wind impeller missing

点,特别是悬空安装的叶片,还要承受风的巨大正压力,因而其造价很高,单机功率越大, 其成本越大,这是至今风电价格高于市电的主要因素之一,相比之下垂直轴风力发电机具有更多的优点。 Point, in particular the installation of floating leaves, but also to withstand tremendous positive pressure of the wind, and therefore its high cost, the greater the stand-alone power, the greater the cost, which is one of the main factors of wind power electricity price is higher than the city so far, with ratio of vertical axis wind turbine under more advantageous.

传统的垂直轴风力发电机都设有一个叶片调整机构,使机构复杂化,造价提高,也大大消耗了风的能量。 Conventional vertical axis wind turbine has a blade adjustment, the agency complicated, the cost increase, but also a significant drain on the wind energy. 而且这种风力发电机不能自起动,附加的起动机构又加重了制造成本,从而导致风能利用系数大打折扣,垂直轴风力发电机的优越性也就荡然无存。 And this is not self-starting wind turbine, an additional starting means has increased the manufacturing cost, resulting in greatly reduced power coefficient, the advantages of a vertical axis wind turbine also gone.

为了有效利用风能,传统垂直轴风力发电机做成变桨距的叶片,但其缺陷是调整叶片攻角的推杆结构,既过多消耗了能量,又造成了风力机不能自行起动。 For efficient use of wind energy, a conventional vertical axis wind turbine blade pitch is made, but the defect is to adjust the angle of attack of the blade putter structure, both excessive consumption of energy, but also resulted in not self-starting wind turbine. 近年来有人发现铰链的叶片在旋转中是可以摆动的,于是就出现了限制钉来把叶片摆动限制在合理攻角中。 In recent years, it was found that leaf hinge in rotation is oscillating, so it was a nail restrictions to limit the blade swings in the corner in a reasonable attack. 但有限制钉就有撞击,在长期、周期及强力撞击下叶片很容易损坏。 But there Nail limited impact, in the long run, cycle and strong impact lower leaves are easily damaged.

目前,采用平行连接杆类型垂直轴风力发电机最多的是日本(2002年开始研究),还有英国、加拿大等国目前也在研制中,这些国家的大部分产品在叶轮设计当中采用平行连接杆, 这种方式对发电机输出轴要求较高,并且结构相对复杂,现场安装程序也偏多。 Currently, the most used parallel connecting rod type vertical axis wind turbines in Japan (study began in 2002), there are currently also developing Britain, Canada and other countries, most of the products of these countries in the use of parallel connecting rods impeller designs this way the output shaft of the generator require a higher, and the structure is relatively complex, the high side field installer. 另外,从力学方面分析,H型垂直轴风力发电机功率越大、叶片越长、平行杆的中心点与发发电机轴的中心点距离越长,抗风能力就越差。 In addition, the mechanics analysis, the greater the H-type vertical axis wind turbine power, the longer the blade, the longer the distance from the center point and the center point of the generator shaft made of parallel rods, wind resistance worse. 同时传统的垂直轴风力发电机要克服传动机构的自重和摩擦力,同时还要克服由于发电机转子自重和机械轴承摩擦带来的阻力,使得传动驱动系统的驱动力增大,降低了发电机效率。 While the driving force of the conventional vertical axis wind turbine to overcome its own weight and friction force transmission mechanism, but also to overcome the resistance due to the weight of the generator rotor and the friction caused by mechanical bearings, such that the drive transmission system is increased, the generator is reduced effectiveness.

因此,为了提高风力发电机的整体性能,达到提高效率、节能、降耗、环保和易普及的目的,必须对传统的垂直轴风力发电机系统进行改造。 Accordingly, in order to improve the overall performance of the wind turbine, to improve efficiency, energy saving, environmental protection and easy popular object, must be modified to a conventional vertical axis wind turbine system. 实用新型内容 SUMMARY

本实用新型的目的就是为了解决上述问题,提供一种具有结构简单,使用方便,能够有效提高风力发电机的整体性能,提高效率、节能、降耗、环保和易普及等优点的磁悬浮自调桨距垂直轴风力发电机。 The purpose of the present invention is to solve the above problems, to provide a simple structure, easy to use, can improve the overall performance of the wind turbine, increase efficiency, and energy conservation and environmental advantages of ease of universal self-adjusting propeller levitation from the vertical axis wind turbine.

为实现上述目的,本实用新型采用如下技术方案: To achieve the above object, the present invention adopts the following technical solution:

一种磁悬浮自调桨距垂直轴风力发电机,它包括磁悬浮风力发电机,磁悬浮风力发电机的发电机轴与叶轮的叶轮轴一体制成,发电机轴穿入电机壳体内,在发电机轴上安装发电机转子,与之对应的电机壳体上设有发电机定子,同时在发电机轴上和电机壳体内还安装轴向 Magnetic Levitation adaptive pitch vertical axis wind turbine, which wind turbine comprises a magnetic levitation, magnetic levitation of the impeller shaft generator wind turbine is integrally formed impeller shaft, the generator shaft penetrating inside the motor housing, the generator mounting a rotor shaft of the generator, the generator stator is provided on the motor housing corresponding thereto, while the shaft of the generator and the motor housing is also mounted axially

磁悬浮装置和径向磁悬浮装置,进行磁悬浮定位;叶轮轴固定安装在轮穀内,叶轮的若干个叶片通过垂直轴自调桨距装置与轮毂相连。 Magnetic suspension means and the radial magnetic levitation apparatus for positioning magnetic levitation; impeller shaft is fixedly mounted on the wheel valleys, a plurality of impeller blades from the vertical axis through the pitch adjusting means is connected with the hub.

所述轴向磁悬浮装置包括设置在电机壳体内部顶端的固定盘,固定盘与发电机轴固联, 在固定盘上设有至少一个环形的轴向上磁体,与之对应的电机壳体上设有相应的轴向下磁铁。 The axial magnetic levitation means comprises a motor disposed inside the top of the housing fixing plate, the fixing plate is fixedly connected with the generator shaft, provided with at least one annular magnet axially, corresponding to the motor housing on the fixed plate provided at respective axial magnet body.

所述径向磁悬浮装置包括设置在发电机轴上的至少一个径向内磁铁,与之对应的电机壳体上设有相应的径向外磁体。 Said radial magnetic levitation means comprises at least one radially inner magnet is disposed on the generator shaft, provided with a corresponding radially outer magnet on the motor housing corresponding thereto.

所述垂直轴自调桨距装置包括一对连接杆,它们与轮毂固联,连接杆另一端与垂直的立杆连接,三者成三角形结构,叶片则通过铰链与立杆铰接,实现自调桨距。 The self-adjusting vertical shaft means comprises a pair pitch connecting rods are fixedly connected with the hub, the connecting rod and the other end connected to the vertical uprights, three triangular configuration, the blade is hinged by a hinge pole, to achieve self-adjusting pitch.

本实用新型在发电机的发电机轴与电机壳体之间去掉了传统的机械轴承而采用了磁悬浮装置,这种结构一方面在垂直轴风力发电机的动力传送方面起到了大大减小摩擦传动的目的, In the present invention, the motor housing between the generator and the generator shaft is removed using conventional mechanical bearing and magnetic levitation apparatus, this configuration functions on the one hand in terms of vertical axis wind turbine transmission power greatly reduced friction transmission purposes,

另一方面也基本克服了由于风力机重量和发电机自身转子的自重所带来的驱动力消耗,由于是全悬浮的,摩擦力小,该机停机后实现了自行起动,垂直轴风力机的优越性全面充分地展现了出来。 On the other hand substantially overcome by the weight of its own weight of the wind turbine rotor and the generator driving force caused by consumption, since the suspension is whole, low friction, stop the machine to achieve a self-starter, a vertical axis wind turbine fully demonstrated the superiority of the full out.

叶轮轴与发发电机轴做成一体,被磁悬浮定位,风力发电机的轴向由永磁磁悬浮推力平衡轴承支撑,轴向上磁铁为一环形磁铁,固定在一固定盘上,并通过固定盘固定在发电机轴上,随发电机轴一起转动,轴向下磁铁固定在电机壳体上,上下磁铁通过斥力相互作用,基本克服了由于风力机重量和发电机自身转子的自重所带来的驱动力消耗。 Leaves hair shaft and generator shaft integrally formed, is positioned magnetic levitation, the wind turbine axial thrust balance by the permanent magnetic levitation bearings, axial magnet is a ring magnet, fixed to a fixed plate, and by a fixing plate fixed to the generator shaft, rotates together with the generator shaft, magnets are fixed on the motor housing, the upper and lower magnet by repulsive interaction, substantially overcomes the axial direction by its own weight and the weight of the wind turbine generator itself brings the rotor the driving force of consumption.

风力发电机径向由磁悬浮定位装置做圆周定位,径向内磁铁为环形,固定在发电机轴上, 径向外磁铁也为一环形,固定在电机壳体上,通过斥力与径向内磁铁相互作用。 Radial magnetic levitation wind turbine made by positioning means circumferentially positioning an annular radially inner magnet, fixed to the generator shaft, a radially outer annular magnet is also fixed to the motor housing, and the repulsive force by radial magnetic interactions. 这样风力发电机的回转部分与定位部分之间摩擦系数几乎为零,与同类传统风力发电机相比传动效率有明显提高。 Between the rotary portion and the positioning portion of such a wind turbine is almost zero coefficient of friction, as compared to similar conventional wind turbines significantly improved transmission efficiency. 同时叶轮不仅能传递较大扭矩给发电机,而且还能够消除机械振动,降低嗓音, 能够不用润滑而长期可靠地工作。 While the impeller can not only deliver greater torque to the generator, but also to eliminate mechanical vibration, lower voice, can no lubrication and long-term reliable operation. 不需要润滑,可以简化风机结构,免除日常的维护保养, 可以长期稳定可靠地工作,同时由于磁轴承的运转阻力为零,因此这也是一种高效节能风机。 Does not require lubrication, it is possible to simplify the structure of the fan, eliminating routine maintenance, long-term stable and reliable work, and because running resistance of the magnetic bearing zero, so this is an energy efficient fan.

为了有效利用风能,传统垂直轴风力发电机做成变桨距的叶片,但其缺陷是调整叶片攻角的推杆结构,既过多消耗了能量,又造成了风力机不能自行起动。 For efficient use of wind energy, a conventional vertical axis wind turbine blade pitch is made, but the defect is to adjust the angle of attack of the blade putter structure, both excessive consumption of energy, but also resulted in not self-starting wind turbine. 本实用新型的垂直轴风力发电机在叶轮设计当中大都采用平行连接杆结构,这种方式对发电机输出轴要求较高,并且结构相对复杂,现场安装程序也偏多。 The present invention most vertical axis wind turbine impeller designs employed in parallel connection rod structure, higher output of the generator shaft in this way requires, and the structure is relatively complex, the high side field installer. 另外,从力学方面分析,H型垂直轴风力发电机功率越大、叶片越长、平行杆的中心点与发发电机轴的中心点距离越长,抗风能力就越差。 In addition, the mechanics analysis, the greater the H-type vertical axis wind turbine power, the longer the blade, the longer the distance from the center point and the center point of the generator shaft made of parallel rods, wind resistance worse.

通常的垂直轴风力发电机,无法保障叶片与气流间保持最佳接触角,且桨距控制系统存在结构复杂,造价高,风能消耗大,无法向大型化发展等缺陷。 Conventional vertical axis wind turbine, the blade can not be ensured between the gas stream and maintain optimum contact angle, pitch control system and the presence of complex structure, high cost, wind energy consumption, not defects such as large-scale development.

本实用新型的叶片通过铰链与立杆相连,叶片可以绕立杆自由转动,每个立杆通过两根连接杆固定在轮毂上,轮毂与叶轮轴固定在一起,叶轮轴直接驱动发电机发电。 The present invention with pole blades are connected by a hinge, the blade may be freely rotated about the pole, each pole by two connecting rods fixed to the hub, the hub and the impeller shaft are fixed together, the impeller shaft directly driven generators. 立杆和两根连接杆构成三角形。 Uprights and two connecting rods form a triangle.

由于采用了特殊空气动力学原理、三角形向量法的连接方式以及直驱式结构的原理,使得叶轮的受力主要集中于轮毂上,因此抗风能力较强,采用三角形向量法的斜撑可以大大减少叶片悬空尺寸。 The use of special aerodynamics Vector delta connection and structure principle of direct drive, so that the force is focused on the impeller hub, so strong wind resistance, the triangular strut vector method can be greatly reducing the size of the floating vane.

与水平轴风力发电机和传统的垂直轴风力发电机相比较,本实用新型的磁悬浮垂直轴风力发电机的叶片与轮臂一端铰连接,实现叶片在叶轮转动中自动调整桨距安装角,不需要复杂的调节机构就能达到最佳迎风角的设计要求,且结构简单、效率高、成本低。 Compared with a conventional horizontal axis wind turbine and the vertical axis wind turbine, the present invention maglev vertical axis wind turbine blade and the hinged end of the arm connected to the wheel, to achieve automatic adjustment of the blade pitch angle in the rotation of the impeller is mounted, no It requires a complicated adjusting mechanism can meet the design requirements of the optimum wind angle, simple structure, high efficiency, and low cost. 叶片始终保持最佳迎风角,产生最大推力,提高发电效率。 The blades always maintain the best wind angle, maximum thrust, improve power generation efficiency. 当风向相对稳定时,叶轮旋转一周,叶片作周期性变化,当叶片处于正顺风向或逆风向两点时,迎风角为零,其他任何位置都有迎风角产生,因而都有推力产生。 When the wind is relatively stable, the impeller rotation, for periodically changing the blade, when the blade is in the positive direction when the upwind or downwind two, zero wind angle, the wind angle in any other location are generated, and thus has a thrust.

当风吹向静止的风力发电机时, 一边叶片与风向相顺, 一边叶片与风向垂直,这样就形成了一架阻力差式风力机,在风力作用下立即起动起来,完成自行启动。 When the wind blows the wind generator to the stationary phase along with the wind direction blade side, the side of the blade and perpendicular to the wind direction, thus forming a differential resistance to wind turbine, in the start-up immediately under the action of the wind, to complete startup. 在启动的瞬时,风力机叶片自动调整为最佳攻角,进入升力型机器正常运转。 In instant start, the wind turbine blade is automatically adjusted to the optimum angle of attack, lift-type machine enters normal operation. 这一过程是完全自动的,而无任何附加装置和外加动力。 This process is entirely automatic, without any additional devices and external power.

本实用新型的叶片每使用一段时间,可以将叶片拆卸下来给予维修,或者直接换上备用的叶片,叶片可以成套的做成尺寸不同的备用配件,根据风力资源情况的不同,使用不同尺寸的叶片,这一点是其它任何风力机不具备的独特之处。 Each blade of the present invention is used for a period of time, the blade may be detached give maintenance, the spare blade or directly, the different sets of blades may be made the size of spare parts, depending on the wind resources using blades of different sizes it is not provided with any other wind turbine is unique. 本实用新型的有益效果是:采用特定的磁路结构,提供一种利用磁悬浮技术减小风力发发电机轴向力和径向力引起的摩擦力。 The beneficial effects of the present invention are: the use of specific magnetic structure, providing a frictional force utilizing magnetic levitation technique reduces wind-power generators axial and radial forces caused. 能有效降低风力发电机的起动阻力矩、起动风速、切入风速,同时能较大幅度提高输出功率。 Can effectively reduce the starting resistance torque of the wind turbine, starting wind speed, cut-in speed, while the output power can be increased substantially. 附图说明 BRIEF DESCRIPTION
