High-protection-level mushroom-shaped ventilation head with fairing

Abstract

The invention discloses a high-protection-level mushroom-shaped ventilation head with a fairing. The high-protection-level mushroom-shaped ventilation head comprises a mushroom-shaped head and a ventilation barrel. A fixing seat is installed at the outer side end of the ventilation barrel. The mushroom-shaped head is connected with the fixing seat. Supporting frames are installed at the two ends of the inner portion of the mushroom-shaped head. Each supporting frame is internally provided with multiple support rods connected in a crossed manner. The outer side end of each supporting frame is provided with a sliding connecting rod. A transmission shaft rod is arranged in the center of the mushroom-shaped head. The fairing is installed at one end of the transmission shaft rod. Sliding block strips are arranged at the two ends of the fairing and connected with the sliding connecting rods in a sliding manner. A hand wheel body is installed at the other end of the transmission shaft rod and guided out to the outer side of the mushroom-shaped head. A filter screen is further arranged in the ventilation barrel. A water storage cavity is further formed in the inner side wall of the ventilation barrel. By means of the above manner, the high-protection-level mushroom-shaped ventilation head can be suitable for entrances and exits of various ship cabins, the structure is firm and stable, rain and water are resistant, and flow-through air is filtered to a certain extent.

Description

technical field [0001] The invention relates to the field of mushroom-shaped ventilation heads, in particular to a high-protection-level mushroom-shaped ventilation head with a deflector cover. Background technique [0002] The fungus-shaped vent head is a special ventilation device for ships. The fungus-shaped vent head is generally used for ballast water tanks and fuel oil tank washing sewage, while some other cabins use gooseneck vent heads. However, the structure of the traditional fungus-shaped ventilation head lacks protection, and it is easy to cause damage to the internal parts under pressure. Moreover, the traditional fungus-shaped ventilation head lacks filtration of the air flowing through it, and it cannot completely overcome the rainwater brought in from the cabin. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a fungus-shaped ventilation head with a high protection level with a deflector, which ca...
