There are Taihang wind turbines, but there are no Dahang wind turbines. A person's weight is not enough to have a significant impact on the rotating wind turbine, because the momentum of the rotation of the blades and the unit is very large. No matter what wind speed the generator is blown by, it is basically impossible for a person to hold it. Just stop.
Why did the wind power stop when the wind was so strong?
It should be that there were some problems during the installation of the wind turbine, causing the first and second stages to There are some flaws in the connection between stages, possibly because a certain screw is not tightened, and then under the influence of other natural environments, this shortcoming is infinitely magnified. But as the saying goes, a slight difference can make a difference a thousand miles. It is this little problem that has led to such disastrous consequences. What happened was undoubtedly a huge economic loss. We have to be warned that we must check repeatedly and carefully during the next construction and installation. Don't let a similar situation happen again. The price paid for such an attempt is still very huge, and there is no room for any mistakes.
In other words, one day in Gaoyou City, Yangzhou, the temperature may have been affected, causing strong winds to blow in the city. There is nothing strange about the strong wind, but what happened next is surprising. The wind, which cannot even blow down a person, blew down a huge wind turbine hundreds of meters high.
When the wind blows, this wind turbine seems a little unstable, swaying left and right in the wind, and looks precarious. As expected, it didn't take long for this behemoth to collapse. . If such a big thing falls from a high altitude, it will naturally cause a very loud noise. Naturally, it also attracted people's attention. With the collapse of the wind turbine, the Jiujiang Highway was broken in half, causing great obstruction to local traffic. At the same time, it also knocked down several wires. After all, the wind turbine itself generates electricity, and there must be surrounding areas. There are wires connected to it to facilitate the transportation of electricity. Fortunately, there were no casualties, just some material losses.
But it is still a pity. After all, this wind turbine has not been installed for a long time, only more than half a year. You must know that when wind turbines were designed, their purpose was to bring more convenience to people’s lives and they could work for many years without being damaged.Wind turbines are expensive to build, but they bring The income is very large, but now it is good, the income has not started yet, and the money has not even been paid back. However, the accident occurred because of the temporary negligence of the construction team.
1. Because wind energy does far more harm to the environment than economic benefits and is not environmentally friendly, it was stopped. The dangers are: 2. Wind power generation will harm the local ecological environment, destroy vegetation, change the terrain, and cause soil erosion and desertification. 3. Wind power generationElectromagnetic radiation affects human habitation. In wind power systems, generators, substations and transmission lines are the main sources of electromagnetic radiation. Additional receivers in wind power plants, when receiving signals, will pick up electromagnetic wave signals reflected by the wind turbine blades. The reflected signal is a lagging signal that has a great impact on AM radio systems. 4. Wind power affects the local climate. Wind power is the use of wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of heat will inevitably produce or consume another type of energy. Therefore, the power generation process of wind turbines will inevitably consume part of the wind energy in the atmosphere. As one of the important factors of climate change, wind energy will inevitably Will bring about climate change. 5. Wind energy blades are prone to safety accidents. When the wind turbine blades of a wind turbine are subjected to strong winds of more than 25m/s, the bending moment, torque, shear strength and extrusion strength that the blade roots can withstand are limited. In severe cases, the entire blade will fly out and cause personnel damage. Casualties and damage to buildings on roads. 6. Noise hazards from wind power generation. For such a large-scale fan, the noise is inevitable when the blades rotate with huge party fees. The noise of the fan blades can be roughly divided into three categories: thickness noise, which is caused by the compression of air and blades. In windy weather, with doors and windows closed, do you often hear sharp and harsh sounds, which feel like howling ghosts and wolves, coupled with the gloomy sky outside, it is a bit scary to think about it; load noise, as the name suggests, is caused by the large load on the blades. ; impulse noise, that is, when the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.
