Abstract

The invention relates to the technical field of filtering devices, in particular to a ventilated and waterproof filtering device. The ventilated and waterproof filtering device comprises a mounting frame, ventilating windows, water fenders and a filter screen component, wherein the filter screen component is mounted inside the mounting frame in an inserting manner, and then fixed through bolts, the water fenders are welded on the mounting frame at the front end of the filtering screen component at equal intervals from the top down, one water fender is welded on each ventilating window, the air ports of the ventilating windows are designed to be downward, a filtering screen is arranged inside the filtering component, the filtering screen is designed to be multi-layered, and comprises two layers at least, and a pull handle is arranged on the filter screen component. The device provided by the invention can prevent rainwater from entering into an engine while ensuring ventilation, the filtering screen is designed to be multi-layered, so that dust can be effectively filtered, and the filter screen component is provided with the handle, so that the demounting and the washing are convenient.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a ventilating and waterproof filtering device. Background technique [0002] As people pay more attention to the environment, it has become a common technology to install filter devices on locomotives to prevent sand and dust from entering the interior of the locomotive, thereby avoiding accidents and shortening the use of electrical appliances and motors in the car due to dust collection. life. However, while installing the filter device, a problem of waterproofing was ignored. The original filter device is usually installed on the side wall of the locomotive, and there is no secondary protection on the outside of the filter, which will cause rainwater to enter the locomotive from the installation interface and the filter screen, thereby affecting the performance of internal electrical appliances and motors, leading to accidents . Contents of the invention [0003...
