Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a submersible waterproof shutter device for an underground facility, especially in an underground public facility, an underground parking lot, an underground shopping street, an underground restaurant, etc. Provided is a safe underground flood control waterproof shutter device which detects the warning water level with a warning sensor for rainwater infiltration and activates the waterproof shutter to completely shut off the water whether the facility is manned or unattended.

2. Description of the Related Art Until now, in the event of heavy rain or heavy rainfall, as a measure to prevent rainwater from entering underground facilities, the work before the old state was continued by surrounding the entrance with vinyl sheets and stacking a large amount of sandbags. ing. In addition, such protective measures took too much time to cope with the sudden increase in rainwater. When working in a special space in an underground facility, a panic occurs due to the intrusion of a large amount of rainwater while spending time without knowing what is on the ground. In addition, it was too late to take measures against inundation, and in the past many victims of damage to goods and human lives have appeared.
Therefore, there is an urgent need to take measures to protect the inundation of underground facilities that can immediately respond to heavy rain.

[0003]

[Problems to be Solved by the Invention] As a measure for flooding rainwater such as heavy rain or heavy rain to underground facilities, flooding was prevented by stacking a large amount of sandbags, but it is not possible to quickly prepare sandbags in urban areas. Moreover, this old method is still problematic. People working in restaurants, shopping streets, parking lots, public facilities, etc. in the special space of the underground facility cannot predict the danger of heavy rain on the ground and increase the water level, and inform them of the danger. Not even doing that. Panic does not occur until the underground flood. In addition, due to the delay in flood protection measures, many accidents have been fatal in the past. Therefore, as a safety measure, it was an urgent task to install waterproof shutters etc.

Buildings are lined up, and asphalt roads are fully equipped with drainage and other sewer systems. In the city, the entire city is made of concrete, so even if it rains a little, there is no penetration of water into the ground. Therefore, in heavy rain or heavy rain, puddle will start to form on roads, sidewalks, etc., and water will flow back from drains, causing rainwater to gain momentum and flow into underground facilities such as low places, causing various types of damage. ing. Therefore, an attempt is made to provide a safe waterproof shutter device for infiltrating underground facilities, which promptly deals with prevention of accidents caused by rainwater.

[0005]

In order to achieve the above-mentioned object, a submersible waterproof shutter device for an underground facility installed in an underground entrance / exit of a building or the like according to the present invention is equipped with a method of detecting rainwater and operating the rainwater inundation alert. A sensor is installed near the entrance. The operation of the waterproof shutter is notified to the general public by voice or a rotating light signal. Detecting the intrusion of rainwater quickly, the waterproof shutter closes with a structure that rises above the road surface, completely protecting the intrusion of rainwater.

[0006]

[Embodiment] The submersible waterproof shutter device for an underground facility formed as described above is buried under the road surface at the entrance / exit. In the buried waterproof storage case, a folding waterproof shutter enters,
In addition, rails for waterproof shutters will be fixed on both sides of the entrance wall. On both sides of the waterproof shutter, tooth patterns similar to the chain mechanism are provided, and the drive wheels mesh with them. If there is a high possibility that the underground water facility will be flooded due to heavy rain or concentrated heavy rain, etc., the rainwater inundation warning detection sensor installed near the entrance will turn on the power motor, the waterproof shutter will rise and the entrance will be closed. Shut off the flood. In addition, both sides are sandwiched by waterproof rollers on the ground slide part of the waterproof shutter to prevent water from entering the waterproof storage case, but when water accumulates in the waterproof storage case, the drainage pump operates and drains out.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The rails shown in Fig. 1 are fixedly installed on both side walls of the entrance and exit of the underground facility. Clothes are applied to the inside of the rail with waterproof rubber. Ten waterproof shutters will be buried under the underground entrance road surface. 2 waterproof shutters are stored in the waterproof storage case, and the waterproof shutters fix the foldable end of 2 to the base of 7. Further, tooth patterns similar to those of the chain mechanism of 3 are provided on both side surfaces of the waterproof shutter of 2 of FIG. 2, and the drive wheels of 4 are engaged therewith. 5 is a power motor. It is a waterproof mechanism that attaches the waterproof shutter between the waterproof rollers 6 and 6'on the ascending / descending portion of the road surface of the waterproof shutter. If rainwater enters the storage case, it will be drained to the U-shaped pit by the drainage pump 8 and the drainage pipe 9. A device to prevent flooding into the underground facility by detecting the rainwater inundation warning sensor near the underground entrance / exit and detecting the warning water level such as heavy rain or heavy rain, closing the entrance by opening the waterproof shutter from the bottom to the top. Is. It shows 13 road surfaces and 14 underground.

[0008]

Since the present invention is constructed as described abnormally, it has the following effects. Even if it is a sudden heavy rain, a heavy rain, etc. To announce. The objective is to provide a safe and reliable waterproof shutter system for flooding underground facilities that can immediately and promptly deal with rainwater intrusion protection measures day and night.

Claims (2)

[Claims] 1. A waterproof shutter device mainly made of iron and rubber is provided at a lower portion of an entrance / exit passage of an underground facility to block vertical opening / closing. A rainwater intrusion warning sensor is installed near the outside of the entrance and exit, and is linked to the waterproof shutter by an electric signal. Incidentally, a tooth mold similar to a chain mechanism is provided on both side surfaces of the waterproof shutter that slides along the rail, and the drive wheels mesh with the tooth mold. 2. An end of a waterproof shutter, which is built in a folding manner in a waterproof storage case that is buried under the road surface at the entrance and exit, is fixed to a pedestal. The other one goes up and down to open and close the underground entrance. It is a device to prevent water from entering the waterproof storage case by sandwiching it with a waterproof roller between the ascending / descending part of the waterproof shutter below the road surface.
