Description

双涵道轴流式风力发电系统 Double-ducted axial flow wind power generation system 技术领域Technical field
本发明涉及风力发电设备技术领域,具体涉及有效提高风能利用率的双涵道轴流式风力发电系统。  The invention relates to the technical field of wind power generation equipment, and particularly relates to a double-ducted axial flow wind power generation system which effectively improves the utilization rate of wind energy.
背景技术Background technique
根据狭管效应而产生的聚风型风力发电机,由于其具有聚集风能、提压增速、提高风能利用率的优点,在风力发电技术领域具有广泛的应用前景。目前的聚风型风力发电装置通常是将进风口设置成一个聚缩狭管,用于提升风速,由于风是因不同位置之间存在压强差而空气流动的结果,风在狭管管道内流动的过程中,流速会受到管道内壁阻力和内部压强的影响,风速的提升实际上非常有限。如中国专利ZL201220394391.6所公开的名称为'一种自启动式狭管聚风风力发电系统'的风力发电装置,由于管内压强随着空气的聚集而逐渐增强,导致管道入口和管道内部之间空气的压强差降低,这会阻碍气流的进一步进入,最终阻碍风速的进一步提升。因此,要有效提高管内的风速,可以从降低管道内壁阻力和增加管道入口与管道内部压强差两个方面进行研究。 其中,管道内壁阻力的降低可以通过改善管道内壁光滑程度来实现,较容易实现;而要使管道入口和管道内部之间的压强差增加,则可以通过增加管道入口的压强或/和降低管道出风口的压强来实现,增加管道入口的压强,可以通过改变聚风口的形状等措施进行改进,而如何降低管道内部的压强则是进一步提升管内风速的研究重点。 The wind-collecting wind turbine generated according to the narrow tube effect has broad application prospects in the field of wind power generation technology because of its advantages of accumulating wind energy, increasing pressure and increasing speed, and improving wind energy utilization. At present, the wind collecting type wind power generating device usually sets the air inlet into a polycondensing narrow tube for raising the wind speed. Since the wind is the result of the air flow due to the pressure difference between the different positions, the wind flows in the narrow tube. During the process, the flow rate is affected by the internal wall resistance and internal pressure, and the increase in wind speed is actually very limited. A wind power generation device named 'a self-starting narrow-tube wind-wind power generation system' disclosed in Chinese Patent No. ZL201220394391.6, as the pressure inside the pipe gradually increases with the accumulation of air, resulting in the relationship between the pipe inlet and the inside of the pipe. The difference in pressure of the air is reduced, which hinders further entry of the airflow and ultimately hinders further increase in wind speed. Therefore, in order to effectively increase the wind speed inside the pipe, it is possible to study the reduction of the inner wall resistance of the pipe and the increase of the pressure difference between the pipe inlet and the pipe. Among them, the reduction of the inner wall resistance of the pipe can be achieved by improving the smoothness of the inner wall of the pipe, which is easier to achieve; and if the pressure difference between the pipe inlet and the inside of the pipe is increased, the pressure of the pipe inlet can be increased or/and the pipe can be lowered. The pressure of the tuyere is realized, and the pressure of the inlet of the pipeline can be improved by changing the shape of the air outlet. How to reduce the pressure inside the pipeline is the research focus of further increasing the wind speed inside the pipeline.

A venting opening is provided on the wall of the tube of the polycondensation tube 11 along the circumference, and the venting opening is provided with a venting door 9 for opening or closing the venting opening.
为了使进入聚缩管一11内的风能尽可能地吹向叶轮4,在叶轮4的前、后两侧分别设有前导风罩7、后导风罩8,且前导风罩7及后导风罩8均为锥形结构,前导风罩7的窄端靠近进风口,后导风罩8的窄端靠近排风口,前导风罩7、后导风罩8分别通过导叶5固定支撑在前管道1的内壁上。 In order to make the wind energy entering the polycondensation tube 11 as far as possible to the impeller 4, the front air hood 7 and the rear air hood 8 are respectively disposed on the front and rear sides of the impeller 4, and the front air hood 7 and the rear guide The windshield 8 has a tapered structure, the narrow end of the front air hood 7 is close to the air inlet, the narrow end of the rear air hood 8 is close to the air outlet, and the front air hood 7 and the rear air hood 8 are fixedly supported by the guide vanes 5 respectively.

本发明中在前管道1内设置的发电机30可以是传统旋转电机、直驱式直线电机、外转子电机等多种形式,图2为本发明的实施例之一,即发电机30采用外转子发电机,所述外转子发电机通过中心轴10和支架20固定支撑在前管道1内, 该实施例的运行方式如下 : In the present invention, the generator 30 disposed in the front duct 1 may be in the form of a conventional rotating electric machine, a direct drive type linear motor, an outer rotor motor, and the like. FIG. 2 is one embodiment of the present invention, that is, the generator 30 is externally used. a rotor generator fixedly supported in the front pipe 1 by the center shaft 10 and the bracket 20, The operation of this embodiment is as follows:
风从聚缩管一11的进风口进入,风速随着聚缩管一11的管道截面积的逐渐缩小而逐渐增强,在前导风罩7的引导下风速进一步增加,并经导叶4调整方向后,冲击叶轮4的叶片,从而将集中的风能转换为叶片的动能,由叶轮4带动外转子发电机内的外转子转动,外转子与内部定子产生相对运动,使发电机30发电,损失大部分能量的风在后导风罩8的导风作用下,经逐渐扩大的尾流管一12排出;聚缩管一11的进风口外侧的风则从聚缩管二21的进风口进入聚缩管二21内,在聚缩管二21的管道内增速之后的气流正好在尾流管一12的出口外围流过,且在尾流管一12的出口外围的气流具有较高的流速,从而进一步降低尾流管一12出口处的压强,在尾流管一12尾部的通孔3周边形成负压,由于在尾流管一12的出口外围的气流流速高于尾流管一12的出口处的风速,因此可带动尾流管一12排风口处的气流加速排出,尾流管一12排出的气流和聚缩管二21尾部的气流汇总后,经逐渐扩大的尾流管二22排出,风的流向如图2中箭头方向所示。 The wind enters from the air inlet of the polycondensation tube-11, and the wind speed gradually increases as the cross-sectional area of the tube of the polycondensation tube 11 gradually decreases. The wind speed is further increased under the guidance of the front air hood 7, and the direction is adjusted by the guide vane 4. Afterwards, the blades of the impeller 4 are impacted, thereby converting the concentrated wind energy into the kinetic energy of the blade, and the outer rotor in the outer rotor generator is driven by the impeller 4 to rotate, and the outer rotor and the inner stator generate relative motion, so that the generator 30 generates electricity and the loss is large. The partial energy of the wind is discharged by the gradually expanding wake tube 12 under the wind guiding action of the rear air hood 8; the wind outside the air inlet of the polycondensation tube 11 enters the air from the air inlet of the polycondensing tube 21 In the shrinkage tube 21, the airflow after the speed increase in the duct of the polycondensation tube 21 flows just outside the outlet of the wake tube 12, and the airflow around the outlet of the wake tube 12 has a higher flow rate. Therefore, the pressure at the outlet of the wake tube 12 is further reduced, and a negative pressure is formed around the through hole 3 of the tail portion of the wake tube 12, since the flow velocity at the periphery of the outlet of the wake tube 12 is higher than that of the wake tube 12 The wind speed at the exit, thus driving the wake The airflow at a 12-row air outlet is accelerated, and the airflow discharged from the wakepipe 12 and the airflow at the end of the polycondensation duct 21 are summed up, and then discharged through the gradually expanding wake tube 22, and the flow of the wind is as shown in the arrow in FIG. The direction is shown.
在聚缩管一11的管壁上沿圆周设有泄风口,且通过设置泄风门9来控制泄风口的开、闭,泄风门9的开、闭可以通过铰链等机械机构来实现,当外部风速过大时,通过控制系统检测并发出信号,控制泄风门9向外翻开从而打开泄风口,通过泄风口的作用,将前管道1、后管道2连通,从而将前管道1内的过大的压强泄至后管道2,从而使前管道1内的风速维持在合理范围内,保护发电机30不过载,确保发电机30的持续稳定发电。 A venting opening is provided on the pipe wall of the polycondensation pipe 11 along the circumference, and the opening and closing of the vent opening is controlled by providing the damper 9, and the opening and closing of the venting door 9 can be realized by a mechanical mechanism such as a hinge, when the external When the wind speed is too large, the control system detects and sends a signal to control the damper door 9 to open outward to open the venting port, and through the action of the venting port, the front pipe 1 and the rear pipe 2 are connected, thereby passing the front pipe 1 The large pressure is released to the rear pipe 2, so that the wind speed in the front pipe 1 is maintained within a reasonable range, and the protection generator 30 is not overloaded, ensuring continuous and stable power generation of the generator 30.
本发明通过前管道1及后管道2的双涵道设计,可以降低叶轮4叶片背面的压强,从而增加叶片正面、背面的压强差,增加叶片的受力,从而提高风能利用率、提高发电机的输出功率,提高发电机效率;本发明配合偏航控制装置作业,根据风向通过偏航控制装置进行控制,使得前管道1的进风口对准风向,以最大限度地捕获风能。 The invention can reduce the pressure on the back surface of the impeller 4 by the double duct design of the front pipe 1 and the rear pipe 2, thereby increasing the pressure difference between the front and the back of the blade, increasing the force of the blade, thereby improving the utilization of wind energy and improving the generator. The output power of the generator improves the efficiency of the generator; the invention cooperates with the yaw control device to control the yaw control device according to the wind direction, so that the air inlet of the front duct 1 is aligned with the wind direction to maximize the wind energy capture.
以上描述是对本发明的解释,不是对发明的限定,本发明所限定的范围参见权利要求,在本发明的保护范围之内,可以作任何形式的修改。 The above description is illustrative of the invention and is not to be construed as limiting the scope of the invention, and the scope of the invention is defined by the appended claims.
