Description

一种空气压缩式垂直型风力发电机组Air compression type vertical wind power generating set 技术领域Technical field
本发明实施例涉及风电技术领域，具体涉及一种空气压缩式垂直型风力发电机组。The embodiment of the present invention relates to the technical field of wind power, in particular to an air compression vertical wind power generating set.
背景技术Background technique
风能是一种清洁的可再生能源，储量巨大，风力发电因其环保的特性日益受到世界各国的重视。Wind energy is a clean and renewable energy with huge reserves. Wind power is increasingly being valued by countries all over the world due to its environmental protection characteristics.
目前风力发电设备世界上利用最多的就是水平式风力发电机，主要由风轮、齿轮箱、发电机、尾舵和塔架组成。风轮在风力的作用下旋转，将风的动能转变为风轮轴的机械能，再通过齿轮箱提速后促使发电机发电。为保持风轮始终对准风向以获得最大的功率，还需安装一个类似风向标的尾舵，并且每台风力发电设备需建立配套的输电塔。At present, the most widely used wind power generation equipment in the world is the horizontal wind turbine, which is mainly composed of a wind wheel, a gear box, a generator, a tail rudder and a tower. The wind wheel rotates under the action of the wind, transforms the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and then promotes the generator to generate electricity after speeding up through the gear box. In order to keep the wind wheel always aligned with the wind direction to obtain the maximum power, a rudder similar to the wind vane must be installed, and a matching transmission tower must be built for each wind power generation equipment.
这种结构的风力发电机，风轮的转速随风速的大小和风向发生变化，当风力小于5m/s时风轮不旋转，无法发电，当风力大于25m/s时，因受到强力风压风轮的转速过快，使发电机超负荷运作，会因过热导致设备损坏甚至引起火灾。风速的不穏导致发电量不稳定，出现脉动现象。风轮的叶片在改变风力时其耐久性是有限的，因此寿命周期短。由于风车叶片、齿轮箱和发电机均设置在塔架的顶端，当发生故障时，不但维修困难而且维修成本过高。而尾舵和塔架的设计也增加了成本和结构的复杂性。With this structure of wind turbine, the rotation speed of the wind wheel changes with the size and direction of the wind. When the wind is less than 5m/s, the wind wheel does not rotate and cannot generate electricity. When the wind is greater than 25m/s, it is subject to strong wind pressure. If the speed of the wind wheel is too fast, the generator will be overloaded and the equipment will be damaged due to overheating and even cause a fire. The poor wind speed results in unstable power generation and pulsation. The durability of the blades of the wind wheel is limited when the wind is changed, so the life cycle is short. Since windmill blades, gearboxes and generators are all arranged on the top of the tower, when a failure occurs, it is not only difficult to repair but also expensive to repair. The design of the rudder and tower also increases the cost and complexity of the structure.
目前垂直型风力发电设备也有研发和报道，但现有的设备因叶片在同一圈里运行，不产生力矩，总体效率低，叶片耐久性不高，过速时的速度控制困难，因此容易损坏，且难以自动启动。At present, vertical wind power generation equipment has also been developed and reported. However, the existing equipment does not generate torque due to the blades running in the same circle, the overall efficiency is low, the blade durability is not high, and the speed control at overspeed is difficult, so it is easy to damage. And it is difficult to start automatically.
发明内容Summary of the invention
本发明提供了一种空气压缩式垂直型风力发电机组，以解决现有风电技术中因风速和风向变化导致发电产生脉动、强风导致设备损害、维修困难等问题，同时简化结构，降低设备生产和维修成本，增加叶片耐久性和速度可控性，延长设备寿命，便于自动启动。The present invention provides an air-compressed vertical wind power generator set to solve the problems of pulsation in power generation due to changes in wind speed and wind direction, equipment damage caused by strong winds, and maintenance difficulties in the existing wind power technology, while simplifying the structure and reducing equipment production and Maintenance costs, increase blade durability and speed controllability, extend equipment life, and facilitate automatic startup.
本发明技术方案所述的空气压缩式垂直型风力发电机组包括支撑架、主轴、叶片、上叶片柱、下叶片柱、上盖、变速器、空气压缩机、储气罐、发电部件和进出门。The air compression vertical wind power generator set according to the technical scheme of the present invention includes a support frame, a main shaft, blades, an upper blade column, a lower blade column, an upper cover, a transmission, an air compressor, an air storage tank, a power generation component and an access door.

本发明具有如下显著的优点：The present invention has the following remarkable advantages:
本发明的主轴和叶片均垂直于水平面，且叶片固定在主轴上，发电部件设置在支撑架的下部或外部，所以方便维护和维修，同时降低维修成本。The main shaft and the blades of the present invention are both perpendicular to the horizontal plane, and the blades are fixed on the main shaft, and the power generation components are arranged at the lower part or outside of the support frame, so it is convenient to maintain and repair and reduce the maintenance cost.
利用叶片收集风能以推动主轴转动，经变速器变速后驱动空气压缩机运转将空气压缩后存储于储气罐中，当风力较大时，叶片收集的风能较多，一部分用来发电，剩余则进行压缩储存，在风力较小时利用压缩空气进行发电，因此发电机转速穏定，可减少发电出现的脉动现象，同时灵活调整发电量和时间。当出现台风和飓风以及无风和微风时，即风力大于25m/s和风力小于5m/s时依然能发电。The blades are used to collect wind energy to drive the main shaft to rotate. After the transmission is shifted, the air compressor is driven to compress the air and stored in the air storage tank. When the wind is strong, the blades collect more wind energy, part of which is used to generate electricity, and the rest is used Compressed storage uses compressed air to generate electricity when the wind is small, so the generator speed is stable, which can reduce the pulsation of power generation, and flexibly adjust the amount and time of power generation. When there are typhoons and hurricanes, as well as no wind and light wind, that is, when the wind is greater than 25m/s and the wind is less than 5m/s, it can still generate electricity.
在本发明中，采用垂直型叶片可增加叶片与风速的接触面，耐久性稳定，而且制造容易，制造成本低。In the present invention, the vertical blade can increase the contact surface between the blade and the wind speed, the durability is stable, and the manufacturing is easy and the manufacturing cost is low.
在本发明中，主轴垂直于水平面，在支撑架上能够为安装多台空气压缩机、储气罐和发电机留有足够的内部空间。In the present invention, the main shaft is perpendicular to the horizontal plane, and enough internal space can be left on the support frame for installing multiple air compressors, air storage tanks and generators.
在本发明中，在上支撑架和下支撑架安装了轨道，叶片在轨道上旋转，以将叶片的荷重向上支撑架和下支撑架分散，既保证叶片在微风中能够旋转，又能使叶片在强风中稳定高速地旋转。In the present invention, rails are installed on the upper support frame and the lower support frame, and the blades rotate on the track to disperse the load of the blades on the upper support frame and the lower support frame, which not only ensures that the blade can rotate in the breeze, but also enables the blade It rotates steadily and at high speed in strong winds.
在本发明中，与水平式风力发电机叶片不同，叶片的上部和下部通过上支撑架和下支撑架进行固定，因此不仅更加牢固，而且大面积叶片面的厚度也更薄，使叶片进一步轻量化。In the present invention, unlike horizontal wind turbine blades, the upper and lower parts of the blade are fixed by the upper support frame and the lower support frame, so that it is not only stronger, but the thickness of the large-area blade surface is also thinner, making the blade lighter. Quantify.
