Description

[0001] APPARATUS FOR INTERCEPTING WATER IN UNDERGROUND VENTILATOR [0002]

[0001] The present invention relates to a shutter type underground ventilating apparatus, and more particularly, to a shutter type underground ventilating apparatus having a shutter for blocking inflow of rainwater into an upper portion of an underground ventilating hole, And more particularly, to a shutter type under-ventilating apparatus.

In general, underground facilities, underground power stations, underground facilities, and other underground facilities are provided with ventilation openings communicating with the ground at appropriate positions in order to maintain a pleasant environment. Since such ventilation openings are usually located on the sidewalk of the road, the entrance is located not so high from the road surface so as not to interfere with the passage of the pedestrian.

On the other hand, although the underground ventilator is installed as an air passage for purifying the air inside the underground facilities, it occasionally functions as an intrusion passage for foreign substances such as sewage or soil, which frequently causes great damage to the underground facilities or the users thereof .

For example, when heavy rainfall or local heavy rainfall occurs in the rainy season, the rainfall exceeds the drainage limit of the road and the roads frequently flood. In this case, the rainwater overflows into the underground ventilator having a height similar to the road surface, By acting as drainage, it causes severe flooding damage to underground facilities.

Especially, when the underground facilities are connected to the substation, there is a risk of submerging the substation, and the lighting, various switchboards and control cables in the power center are flooded, and it takes a lot of time and money for restoration. It will bring about a situation.

Therefore, it is desirable that the ventilation hole is appropriately closed when the underground ventilation hole is maintained in the open state and the rainfall in the rainy season or the like is much lowered and flooding of the road is feared. As a technology for this, Korean Utility Model Publication No. 1999-7945 .

In the Utility Model No. 1999-7945, when the driving shaft of the speed reducer is manually or reversely rotated using a separate tool, the arm installed on the driven shaft is rotated, and the link is pulled or pushed so that the hinge thereby opening and closing the hinged car door.

However, in such a link-type vehicle ventilating opening, the opening of the ventilating hole is poor due to the fact that the car water gate is not completely turned toward the wall when the ventilating hole is opened, and an excessive load is applied to each component in the structure, There was a problem.

In addition, a separate opening and closing tool is required. Especially, since it is manually operated, it takes considerable time for the local dispatch to shut down in case of local heavy rains. Therefore, it is inevitable to undergo some immersion of underground facilities.

SUMMARY OF THE INVENTION The present invention has been accomplished in order to solve the problems of the prior art, and it is a primary object of the present invention to provide an underground ventilator having a shutter for opening and closing an underground ventilator, The present invention provides a shutter type underground ventilating apparatus.

It is still another object of the present invention to provide a shutter type underground ventilating apparatus capable of minimizing loads due to rain by blocking rain from the upper part of the underground ventilator and simplifying the structure of the water intake system. have.

In order to achieve the above-mentioned object, the shutter type underground ventilator receiving apparatus of the present invention comprises: a first grating; A second grating; shutter; And first driving means.

At this time, the second driving means; And a cam.

The first driving means may include a driving motor; And a winding means.

Further, the driving motor is further provided with an operation handle.

The shutter may further comprise a wire; Closing member; And at least one guide roller.

Further, the shutter is further provided with a weight.
