Vertical shaft involute wind wheel direct drive special-shaped wind turbine

technical field

The utility model relates to a vertical axis wind power generator. the

Background technique

Wind energy is a clean, safe, and renewable green energy. With the enhancement of people's awareness of environmental protection in recent years, it has gradually become a new energy that is vigorously developed and utilized by countries all over the world. In the field of wind energy, the development of international wind power generators, on the one hand, tends to be more and more large-scale, and the capacity of single wind turbines continues to increase; on the other hand, there are also some small wind power generators. the

Existing wind turbines mainly include horizontal-axis wind turbines and vertical-axis wind turbines. The blade design of horizontal-axis wind turbines is generally based on the momentum-blade element theory. The main methods are Glauert method, Wilson method, etc. . However, since the blade element theory ignores the flow interference between blade elements, and the resistance of the airfoil is ignored when applying the blade element theory to design blades, this simplification inevitably leads to inaccurate results. This simplification The impact on the shape design of the blade is small, but it has a greater impact on the wind energy utilization rate of the wind rotor. At the same time, the interference between the blades of the wind wheel is also very strong, and the entire flow is very complicated. It is completely impossible to obtain accurate results if only relying on the blade element theory. The blade design of the vertical axis wind turbine was also designed according to the design method of the horizontal axis in the past, relying on the blade element theory. Because the flow of the vertical axis wind rotor is more complicated than that of the horizontal axis, it is a typical large separation unsteady flow, which is not suitable for analysis and design by blade element theory. the

At present, the wind energy utilization rate of large horizontal axis wind turbines is mostly calculated by the blade design method, which is generally above 40%. As mentioned earlier, due to the defects of the design method itself, the accuracy of the calculated wind energy utilization rate is very doubtful. Of course, the wind power generators in the wind farm will draw wind power curves according to the measured wind speed and output power, but the wind speed at this time is the wind speed measured by the anemometer at the rear of the wind wheel, which is smaller than the incoming wind speed, and the wind power curve High and must be corrected. After the correction method is applied, the utilization rate of wind energy on the horizontal axis will be reduced by 30% to 50%. Regarding the wind energy utilization rate of small horizontal axis wind turbines, the China Aerodynamic Research and Development Center has conducted related wind tunnel experiments, and the actual measured utilization rate is 23% to 29%. It is a consensus that the starting performance of the horizontal axis wind turbine is good, but according to the wind tunnel experiments conducted by the China Aerodynamic Research and Development Center on small horizontal axis wind turbines, the starting wind speed is generally between 4 and 5m/s, and the maximum The actual speed reaches 5.9m/s, such starting performance is obviously unsatisfactory. The poor starting performance of the vertical axis wind rotor is also the current consensus in the industry, especially for the Darrieus type Φ type wind rotor, which has no self-starting ability at all, which is also a reason for limiting the application of vertical axis wind turbines. The study found that as long as the airfoil and installation angle are selected properly, quite good starting performance can be obtained. Through the wind tunnel experiment of the experimental vertical axis wind turbine, the measured starting wind speed only needs 2m/s, which is better than the above level shaft wind turbine. the

The blades of the horizontal axis wind turbine are subjected to the combined action of inertial force and gravity during one revolution. The direction of inertial force changes at any time, while the direction of gravity remains unchanged, so the blades are subjected to an alternating load. , which is very detrimental to the fatigue strength of the blade. In addition, the generators with the horizontal axis are placed at an altitude of tens to hundreds of meters, which brings a lot of inconvenience to the installation, maintenance and overhaul of the generators. The force of the blades of the vertical axis wind rotor during the rotation process is much better than that of the horizontal axis. Since the direction of the inertial force and gravity is always the same, the load is constant, so the fatigue life is longer than that of the horizontal axis wind turbine. Wheel length. At the same time, the vertical axis generator can be placed under the wind rotor or on the ground, which is convenient for installation and maintenance. The installation height of the vertical axis wind rotor is relatively much lower. the

The speed-up transmission of the traditional wind turbine is completed by the gear box. Generally, the gear box weighs more than ten tons to dozens of tons, and the whole engine room is tens to more than one hundred meters above the ground. Once a fault occurs, not only the maintenance is difficult, but also the maintenance cost Also very high. The gearbox is a high-failure part of the wind turbine. With the continuous increase of the power of the wind turbine unit, its high failure rate and limited life have become a major bottleneck in the operation of wind power. the

Although wind power is also known as clean energy and can play a very good role in environmental protection, with the establishment of more and more large-scale wind farms, some environmental problems caused by wind power generators have also become prominent. These problems are mainly reflected in two aspects: one is the noise problem, and the other is the impact on the local ecological environment. The blade tip speed ratio of the horizontal axis wind rotor is generally around 5 to 7. At such a high speed, the cutting airflow of the blade will produce a lot of aerodynamic noise. At the same time, many birds are hard to escape under such a high speed blade. The tip speed ratio of the vertical axis wind rotor is much smaller than that of the horizontal axis, generally between 1.5 and 2. Such a low speed basically does not generate aerodynamic noise, and completely achieves the effect of silence. The benefits of no noise are obvious. The occasions where wind turbines could not be used due to noise problems (such as urban public facilities, residential buildings, etc.) can now be solved by using vertical axis wind turbines. The benefits of low tip speed ratio Not only the advantages of environmental protection, but also very beneficial to the overall performance of the fan. From the perspective of aerodynamics, the faster the object, the greater the impact of the shape on the flow field. When wind turbines operate outdoors, the blades are inevitably polluted, which actually changes the shape of the blades. For the horizontal axis wind rotor, even if the shape change is very small, it will greatly reduce the wind energy utilization rate of the wind rotor, while the vertical axis wind rotor is not sensitive to the shape change because of the low speed. Contamination has essentially no effect on the aerodynamic performance of a vertical axis rotor. the
