Ventilation and noise reduction device for shelter
The invention discloses a ventilation and noise reduction device for a shelter. The ventilation and noise reduction device is characterized in that an air inlet and outlet are formed in a shelter body of the shelter, and the ventilation and noise reduction device comprises a wind shielding piece and a noise reduction assembly; the wind shielding piece is fixed at the air inlet and outlet; the noise reduction assembly is connected with the wind shielding piece, the wind shielding piece forms a ventilation channel so that the noise reduction assembly can be communicated with the air inlet and outlet, the noise reduction assembly comprises one or more noise reduction pipes, a plurality of first noise reduction holes are formed in the surfaces of the noise reduction pipes, and cover plates are arranged at one end or two ends of each noise reduction pipe. According to the ventilation and noise reduction device for the shelter, the noise reduction assembly is communicated with the air inlet and the air outlet through the wind shielding piece, wind shielding, dust prevention and rain prevention are facilitated, the first noise reduction holes are formed in the first ventilation pipe, the overall region of the first noise reduction holes is increased, the sound absorption coefficient is increased, noise is remarkably reduced, and interference and harm to workers are reduced.
本发明公开了一种用于方舱的通风降噪装置，方舱的舱体上设有进排风口，通风降噪装置包括挡风件和降噪组件；挡风件固定在进排风口处；降噪组件与挡风件连接，挡风件形成通风通道使得降噪组件和进排风口连通，降噪组件包括一个或多个降噪管，降噪管表面设有多个第一降噪孔，降噪管的一端或两端设有盖板。本发明提供的用于方舱的通风降噪装置通过挡风件连通降噪组件和进排风口，有利于挡风、防尘和防雨，通过在第一通风管上设置第一降噪孔增大了第一降噪孔整体的面积，有利于提高吸声系数，进而显著降低噪声，减少对工作人员的干扰和伤害。
