By securing the watertightness of the order door securely, it is related to the order of the underground ventilation hole to protect the underground structure by completely blocking the rain to penetrate into the underground structure through the ventilation opening during heavy rains, such as the rainy season.

In general, various underground structures such as subway stations, underground co-orches or basement floors are provided with ventilation holes communicating with the ground for ventilation, and the entrances of the ventilation holes are located not too high from the ground surface.

These vents are installed as air passages for the indoor air purification of the underground structures, but sometimes they become intrusion passages such as sewage, which causes great damage to the underground structures.

In particular, when heavy rains such as rainy season do not drain the road smoothly, rainwater overflows frequently into the vents, which act as a channel connecting the ground and underground structures, causing serious damage to underground structures. I was letting go.

Therefore, there is an urgent need for a ventilating order device capable of efficiently closing the vent when the level of the road surface increases due to a lot of rain while keeping the vent open.

Accordingly, as a recent draft, a link door for a ventilation system such as Korean Utility Model Publication No. 1999-7945 has been disclosed.

As shown in Fig. 1, the order door for the ventilation opening is driven by the order door 1 being hinged to the inside of the ventilation opening, and the driven shaft 3a of the reduction gear 3 provided on the side wall 2 of the ventilation opening rotates. The arm 4 pinned in (3b) is rotated so that the order door 1 connected by the link 5 can be opened and closed.

That is, when the rotary shaft 3a of the reducer 3 is rotated in one direction by the manpower using the rotating tool H, the arm 4 pinned to the driven shaft 3b is rotated clockwise to thereby link 5 By pulling upwards, the order door 1 is opened. On the contrary, when the main shaft 3a is rotated, the arm 4 pushes the link 5 downward so that the order door is closed.

However, such a link-type ventilation door for the door has a problem that can not be opened 100% because the door is not completely off the wall side in opening the vent.

In addition, mechanical loads on the mechanical components are excessively difficult to use because it takes a lot of power and time to perform the opening and closing work, and there is a problem that the durability is remarkably decreased, such as frequent mechanical failures.

In addition, since the drainage means for discharging the accumulated water to the outside after the situation is not provided at the top of the vent door, it is very cumbersome and additionally incurs the additional cost of pumping. there was.

On the other hand, due to the installation of the order door is inevitable to remove the auxiliary ladder installed on the upper wall surface of the ventilation opening, there is another problem that is very inconvenient for the ground worker to climb up and down to the existing rotating stairs installed inside the ventilation opening.

Therefore, the above-described conventional link-type ventilation doors do not meet the requirements for efficiently operating the ventilation doors of the ventilation openings, and are merely technologies that cannot be applied to the actual site.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and it is possible to open the ventilation holes as a whole by a mechanical drive type using wires and worm gears, and to quickly and easily open and close the door. By ensuring the watertightness of the order door securely, the rainwater in order to protect the underground structure is provided by completely blocking the rainwater to penetrate into the underground structure through the ventilation opening during heavy rains. There is a purpose.
