Abstract

PURPOSE:To attenuate wind pressure and noise, by depositing a thermoplastic net- form material from the round side to the porous frame material of the outside to prevent vibration of the net-form material and extend the interval to the power generation unit. CONSTITUTION:Wind screen 3 surrounds power generation unit 2 and is formed with the frame consisting of rough gauze and net 5 caused to adhere to the inside. Gauze 4 is solid because metallic wires interscets one another orthogonally. Net 5 of the inside consists of, for example, thermoplastic low-melting point fibrous materials and is fused by heating at 100 deg.C approximately and is caused to adhere closely to gauze 4. Therefore, vibration dependent upon wind pressure is reduced, and noise is difficult to generate. Net 5 has a low resonance sharpness because of thermoplastic materials and adsorbs effectively vibration of air passing through meshes, and resonance sharpness of gauze 4 can be lowered.
