The invention discloses a ventilator cover with waterproof and breathable functions and a switch machine. The ventilator cover comprises a machine cover plate and a ventilation cover plate, the lower end of the left side of the machine cover plate is provided with two folding lugs which are distributed front and back at an interval; a horizontally and transversely distributed pressing plate is arranged in the middle of the lower end of the right side of the machine cover plate; a manual module and a ventilation module are arranged at an opening in the front side of the cover plate of the machine cover; the manual module is used for enabling a crank connector of a crank to be in butt joint with a hand shaft on an original motor speed reducer of the switch machine after the crank connector of the crank is inserted in a penetrating mode; a hand-cranking shaft on an original motor speed reducer of the switch machine is located in a hollow machine cover plate. And the ventilation module is used for playing waterproof and breathable roles and enabling air to flow into the cover plate of the machine cover. According to the invention, on the premise that the sealing protection performance is not reduced, the ventilation capability of the switch machine is improved, so that the purpose that only air flows inside and outside the switch machine and water vapor does not flow is achieved, and condensation in the switch machine is effectively avoided.
本发明公开了一种具有防水透气功能的通风机盖及转辙机,通风机盖包括:机盖盖板;机盖盖板的左侧下端,设置有前后间隔分布的两个折页耳;机盖盖板的右侧下端中部,设置有水平横向分布的压板;机盖盖板的前侧,开口设置有手动模块和通风模块;手动模块,用于让手摇把的摇把接头贯穿插入后,与转辙机原有的电机减速器上的手摇轴相对接;转辙机原有的电机减速器上的手摇轴,位于中空的机盖盖板里面;通风模块,用于发挥防水透气的作用,能够让空气流入机盖盖板内部。本发明能够在不降低密封防护性能的前提下,提高转辙机的通风透气能力,以达到转辙机机内和机外只流通空气而不流通水汽的目的,有效避免转辙机机内产生凝露。
