The main raw materials used in the production of wind turbine blades are composite materials, including resin materials, carbon fiber materials, glass fiber materials, etc., but currently the most commonly used are resin materials (polyester resin, vinyl ester resin, epoxy resin); Compared with other chemical materials, the above materials are all environmentally friendly materials with low toxicity and low pollution. Moreover, wind energy itself belongs to the category of new green energy; also environmentally friendly materials. There is no serious pollution or dust or noise in the blade production workshop. Generally speaking, the company's working environment is good and not harmful to the body.
1. Because wind energy does much more harm to the environment than economic benefits and is not respecteduer of the environment, she was arrested. 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. Electromagnetic radiation generated by wind power affects human habitation. In wind energy 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 the electromagnetic wave signals reflected from the wind turbine blades. The reflected signal is a delayed signal that has a great impact on AM radio systems. 4. Wind energy 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 a type of cwill inevitably produce or consume another type of energy. Therefore, the energy production process of wind turbines will inevitably consume part of the wind energy in the atmosphere. one of the important factors of climate change, wind energy will inevitably lead to climate change. 5. Wind turbine blades are prone to safety accidents. When wind turbine blades are subjected to strong winds of more than 25 m/s, the bending moment, torque, shear resistance and extrusion resistance that the blade roots can withstand are limited. In severe cases, the entire blade will fly. and causing injury to personnel and damage to buildings on roads. 6. Noise risks linked to wind energy production. For a fan of such magnitude, noise is inevitable as the blades spin with huge party costs. The noise of the fan blades is littlet be roughly divided into three categories: thickness noise, which is caused by the compression of the air and the blades. On windy days, with doors and windows closed, do you often hear high-pitched and harsh sounds, which sound like ghosts and wolves howling, coupled with the dark sky outside, it's a little scary to thinking about it, as the name suggests; suggests, is caused by the heavy load on the blades; impulse noise, that is to say when the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.
