Wind-proof and snow-proof large-size roof ventilator
A windproof and snow-proof large-size roof ventilator comprises a plurality of ventilator frameworks, rain baffles and symmetrically-arranged outer protection plates. A cross beam is arranged between the lower ends of the two stand columns of each ventilator framework, M-shaped supports are arranged on the cross beams, two flow guide plates are symmetrically arranged in the middles of the M-shaped supports of the ventilator frameworks, two valve plates are symmetrically arranged on the two sides of each M-shaped support respectively, one side of each valve plate is hinged to the upper end of the outer side of the corresponding flow guide plate, and the other side of each valve plate is hinged to the lower end of the corresponding flow guide plate. Opening and closing devices are symmetrically arranged between the valve plates and the ventilator framework and are rigidly connected with the valve plates; flashing plates are symmetrically arranged among the plurality of ventilator frameworks, and the valve plates are pressed on the flashing plates when being closed; and the valve plate extends upwards along the inclination of the guide plate after being opened. The ventilator can reduce the boundary dimension of the valve plate, is additionally provided with a maintenance safety channel, is convenient to manufacture, transport, install and maintain, is prevented from being damaged by wind power, and reduces accumulated snow leakage of the valve plate; the ventilator can be used as a newly-built ventilator and can also be used as an improvement of an existing ventilator.
一种防风、防雪大规格屋顶通风器，包括多个通风器构架、挡雨板和对称布置的外护板；在每个通风器构架的二根立柱下端之间分别设有横梁，在横梁上设有M型支架，在多个通风器构架的M型支架中部对称设有二个导流板，在M型支架两侧分别对称设有二个阀板，阀板一侧铰接在导流板的外侧上端，在阀板与通风器构架之间对称设有启闭装置，启闭装置与多个阀板刚性连接；在多个通风器构架之间对称设有泛水板，阀板关闭时压在泛水板上；阀板开启后沿导流板斜度向上延伸。该通风器能够减小阀板外形尺寸并增加了检修安全通道，便于制作、运输、安装和检修，防止受风力破坏，减小阀板积雪渗漏；可作为新建通风器应用也可作为现有的通风器改造。
