The invention belongs to a waterproof ventilation method for a maintenance-free sealing detector and a point switch. The waterproof ventilation method is characterized in that a ventilation cover (2-1), a sealing gasket (2-2), a steel wire mesh (2-3), a sponge cushion (2-4), a sponge cover (2-5) and a fastener group (2-6) are included; and the bottom face of the ventilation cover (2-1) and the sealing gasket (2-2) are fixed to form a first whole, the steel wire mesh (2-3) and the sponge cushion (2-4) are fixed to the bottom of the sponge cover (2-5) to form a second whole, connecting holes are formed in the centers of the first whole and the second whole, and the fastener group (2-6) is fastened through the connecting holes in the centers of the first whole and the second whole. The waterproof ventilation method of the maintenance-free sealing detector and the switch machine can be applied to the conditions that the humidity in the machine is high, the ventilation requirement is met, the waterproof performance grade is high, installation is convenient, applicability is high, the humidity in the machine is automatically reduced under the condition that a cover is not opened, and ventilation is achieved.

    本发明属于一种免维护的密检器和转辙机的防水透气方法,其特征是:包括透气盖(2‑1)、密封垫(2‑2)、钢丝网(2‑3)、海绵垫(2‑4)、海绵盖(2‑5)、紧固件组(2‑6);透气盖(2‑1)底面和密封垫(2‑2)固定为第一整体,钢丝网(2‑3)和海绵垫(2‑4)固定在海绵盖(2‑5)的底部形成第二整体,第一整体和第二整体中心有连接孔,紧固件组(2‑6)通过第一整体和第二整体中心连接孔进行紧固。这种免维护的密检器和转辙机的防水透气方法可应用于有较高机内湿度、有透气要求、防水性能等级高,具有安装方便,适用性强,在不开盖的情况下自行降低机内湿度、通风换气。
