Description

A waterproof ventilation duct for civil air defense projects

Technical Field

The utility model relates to the field of civil air defense engineering, in particular to a waterproof ventilation duct for civil air defense engineering.

Background Art

The ventilation equipment in civil air defense projects uses means such as air exchange dilution or ventilation exclusion to achieve the exchange and circulation of air inside the civil air defense projects with the outside air, thereby meeting the breathing needs of people in the civil air defense projects.

Existing ventilation ducts are usually buried deep underground. Since the air underground is relatively humid, there will usually be water accumulated on the walls of the ducts. When it rains outside, rainwater may seep into the ground and enter the ducts. When it accumulates to a certain level, it will flow in the ducts until it flows into the underground facilities through the vents, causing many inconveniences.

Utility Model Content

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a waterproof ventilation duct for civil air defense projects, which solves the current pain points in this field.

The above technical objectives of the utility model are achieved through the following technical solutions:

A waterproof ventilation duct for civil air defense projects comprises an air duct, a side of the air duct is connected to an air guide pipe, the other end of the air guide pipe is a vent in a basement and the pipe is inclined upward, a water collector is connected to the bottom of the air duct, a guide plate is fixedly installed below the interface between the air guide pipe and the air duct, and the guide plate does not completely cover the top of the water collector.

It is further explained that the bottom end of the water collector is connected to a drain pipe.

It is further explained that a check valve is provided in the water collector.

To sum up, the beneficial effects of the utility model compared with the prior art are as follows: the inclined setting of the air duct can make the water therein flow away from the air outlet, and the water in the ventilation duct can flow into the water collector after being collected and discharged uniformly through the drain pipe, thereby preventing water from flowing out of the ventilation port and affecting the internal environment of the civil air defense facility.
