The invention relates to a power cabin and engineering machinery with the same. The power cabin comprises a cabin; the engine is arranged in the cabin and is provided with a cooling liquid flow path through which cooling liquid flows; the radiator is arranged in the cabin and is communicated with a cooling liquid flow path of the engine; the ventilation opening is formed in the cabin and used for introducing air exchanging heat with the radiator or discharging air exchanging heat with the radiator; the noise reduction unit is arranged on the ventilation opening and comprises a first grid, a second grid and a first elastic component, the second grid and the first grid are arranged in a stacked mode in the thickness direction of the wall of the cabin, the distance between the first grid and the second grid is adjustable, and the first elastic component pushes and presses the first grid towards the second grid; the first grille comprises a plurality of first air ports arranged side by side and first solid parts located between every two adjacent first air ports, and the second grille comprises a plurality of second air ports arranged side by side and second solid parts located between every two adjacent second air ports. The projection of the second air opening in the plane perpendicular to the thickness direction is partially or completely overlapped with the projection of the first solid part in the plane, so that the first grating is driven by air discharged from the second air opening in the direction away from the second grating.

    本发明涉及一种动力舱及具有其的工程机械,动力舱包括:舱室;发动机,设置在舱室内,并具有流通冷却液的冷却液流路;散热器,设在舱室内,并与发动机的冷却液流路连通;通风口,设在舱室上且用于引入与散热器换热的空气或排出与散热器换热后的空气;降噪单元,设在通风口上,降噪单元包括第一格栅、与第一格栅沿舱室的壁的厚度方向层叠布置且与第一格栅间距可调的第二格栅以及将第一格栅朝第二格栅推压的第一弹性部件,第一格栅包括并排布置的多个第一风口和位于相邻的两个第一风口之间的第一实体部,第二格栅包括并排布置的多个第二风口和位于相邻的两个第二风口之间的第二实体部,第二风口在垂直于厚度方向的平面内的投影与第一实体部在平面内的投影部分或全部重叠,以使第二风口的出风将第一格栅朝远离第二格栅的方向驱动。
