Abstract
The invention discloses a waterproof device for an automobile exhaust pipe. The waterproof device comprises an elbow pipe, wherein the upper end of the elbow pipe is hermetically connected with an opening of the exhaust pipe; a plurality of thin pipes for exhaust are arranged in the elbow pipe side by side and are fixed in the elbow pipe by a plurality of locating plates; a water stopping valve is mounted at the lower end of the elbow pipe; both the lower end of the elbow pipe and the water stopping valve are inclined relative to the horizontal plane; the water stopping valve comprises a cover body fully covered with meshes and rubber balls with the same amount as the thin pipes; the rubber balls are arranged below the openings of the thin pipes respectively and clearances are reserved between the rubber balls and the openings of the thin pipes; and the diameter of each rubber ball is greater than those of the thin pipes and the meshes. Under a normal condition, the rubber balls do no block the openings of the thin pipes under the action of airflow, and tail gas is discharged through the exhaust pipe, the thin pipes and the meshes of the cover body. When an automobile wades, the rubber balls can block the openings of the thin pipes to prevent water from entering under the action of buoyancy, while the tail gas can still be discharged from the openings of the thin pipes in a higher position.
