[0002] With the continuous growth of global demand for clean energy, wind power generation, as a sustainable energy solution, has achieved rapid development in the past few decades. In order to solve the noise problem of wind power generation institutions, some noise reduction technologies have been adopted, such as installing sound-absorbing materials in the cabin and using sound insulation covers. Although sound insulation covers can effectively reduce the overall noise, they have problems such as heavy weight, difficult installation and maintenance, and affecting ventilation and heat dissipation. As mentioned above, the sound insulation cover may have problems such as aging of sound insulation materials, damage to seals, deformation of supporting structures, etc., resulting in a decrease in noise reduction effect.

[0003] During use, the existing device may cause the installation and disassembly steps of the noise reduction device to be too complicated, resulting in too much time being wasted in disassembling the noise reduction device when the wind turbine needs to be repaired, thereby affecting the efficiency of normal operation. In addition, the existing device may cause the noise reduction device to be unstable due to the vibration generated by the wind turbine, and may be damaged due to long-term wear. Summary of the invention

[0004] The object of the present invention is to provide a noise reduction device for a wind power generation mechanism, which can be quickly disassembled to save time during maintenance, and can more stably fix the noise reduction device without sealing the generator to affect heat dissipation.

[0006] Moreover, a first connecting block is symmetrically fixedly connected to the shell, and a second connecting block is fixedly connected to the first connecting block.

[0007] Moreover, a third connecting block is fixedly connected to the second connecting block.

[0015] 2. The present invention adopts a support frame, and a support frame is arranged inside the shell to more stably support the shell and enhance the stability of the shell.
