The ceiling comprises a locomotive mechanism, a shutter mechanism and a limiting mechanism, the locomotive mechanism comprises a shed and a ceiling body arranged on the top of the shed, and a ventilation opening is formed in the bottom of the ceiling body; the shutter mechanism comprises two vertical plates which are arranged on the top of the ceiling and located above the ventilation opening, a plurality of blades are sequentially and rotationally connected between the two vertical plates, and the tail portions of the blades are rotationally connected between the two vertical plates. The limiting mechanism comprises closing limiting pins which are arranged on the two vertical plates and located below the head portions of the blades, and opening limiting pins are arranged on the two vertical plates and located below the tail portions of the blades. And after the ventilator on the electric cabinet is closed, the blades abut against the closed limiting pins under the action of the gravity of the blades, the blades are closed, automatic opening and closing of the blades are achieved, and energy conservation and environmental protection are achieved.
本发明公开了一种带活动百叶窗的顶棚,包括机车机构、百叶窗机构以及限位机构,机车机构包括车棚以及设于车棚顶部的顶棚,顶棚底部设有通风口;百叶窗机构包括设于顶棚顶部的位于通风口上方的两个立板,两个立板之间依次转动连接有多个叶片,叶片尾部转动连接于两个立板之间;限位机构包括设于两个立板上的位于叶片头部下方的闭合限位销,两个立板上位于叶片尾部的下方设有开启限位销,本发明的有益效果是:当电柜上的通风机通风后,通风口内涌入大量气流,气流顶开叶片,叶片抵接于开启限位销上,将气流排除车外,当电柜上的通风机关闭后,叶片在自身的重力作用下,叶片抵接于闭合限位销上,叶片关闭,实现了叶片的自动启闭,节能环保。
