Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof door which is installed at an entrance of a building, an underground parking lot or the like, and has a mechanism for standing up by detecting the intrusion of water due to heavy rain.

[0002]

2. Description of the Related Art Conventionally, waterproof doors installed in facilities such as buildings and underground parking lots have a mechanism for opening and closing the waterproof doors on both sides at right and left sides through vertical axes at entrances and exits, or a horizontal arrangement on a floor surface. There is a mechanism in which a preventive door is vertically rotated through a shaft and rises from the floor surface.

[0003] The opening and closing of these waterproof doors is performed by a building manager manually or by a hydraulic device when the road overflows due to heavy rain or the like and there is a risk of flooding due to rising water levels. That is the current situation.

[0004]

However, the waterproof door of each of the above-mentioned mechanisms requires manual operation and requires a 24-hour monitoring system, resulting in a very high management cost. There is.

[0005] In addition, a sudden change due to inundation due to the collapse of a river cannot be sufficiently handled by manual operation.
It is impossible to deploy a resident clerk, and most buildings and other underground parking lots do not have waterproof doors. Furthermore, in the event of a disaster, there are many accidents such as power outages,
Therefore, it is often difficult to operate the waterproof equipment by electric power as desired.

Accordingly, an object of the present invention is to provide a waterproof door which automatically opens and closes by using water that enters without being manually operated.

[0007]

The above object of the present invention can be achieved by a waterproof door having the following structure. That is, the point is that a pit for water storage is provided under the floor of the entrance of the facility such as an underground parking lot, a water inlet communicating with the pit is opened on the entrance side of the water of the entrance, and the pit is along the entrance. A waterproof door provided with an opening groove communicating with the inside and a gate that rises above the opening groove and shuts off the entrance due to the level of water flowing into the pit due to buoyancy in the pit. It is.

[0008] Further, by providing a drainage mechanism in the pit, a danger is sensed by inflow water exceeding a normal drainage amount,
The mechanism is such that the gate is raised and the water in the pit is discharged by natural drainage when there is no danger of flooding.

Further, a partition plate for preventing the gate from being raised by the inflowing water pressure and a protection plate for protecting the gate and passing the vehicle (to a certain height of the gate) are provided in the pit. Configuration.

[0010]

Embodiments of the present invention will be described below.
This will be described in detail with reference to the drawings showing the embodiment. Example 1 As shown in FIG. 1, a pit 1 is provided below a floor of an entrance B of a facility A such as an underground parking lot toward the front of the entrance B (water entry side).

In the pit 1, a gate 3 to which a float 2 is attached is accommodated below the pit 1. The gate 3 is formed by an opening groove 4 which is opened between the entrance B and the inside of the pit 1 so as to communicate with the inside of the pit 1 and upper and lower sliding grooves 5 and 5 engraved along the vertical direction of both wall surfaces of the entrance B. When water enters the pit 1, the buoyancy of the float 2 raises the gate 3 above the floor between the entrances B.

In view of this, a water inlet 6 is provided on or near the pit 1 on the vehicle entrance side or in the vicinity thereof so as to communicate with the inside of the pit 1. Between the water inlet 6 and the gate 3, there is provided a partition plate 7 having a gap formed between its lower end and the bottom of the pit 1. Therefore, this partition plate 7
Thus, the gate 3 can open and close the entrance B without any trouble without being affected by the water pressure flowing from the water introduction port 6 or the like.

Embodiment 2 FIG. 2 shows a structure in which a drain groove 8 is provided in the pit 1. The drain groove 8 communicates with the sewer, and is connected to the pit 1 through the water inlet 6 by general rainfall. For the ingress of water into the pit 1, water is drained without collecting water in the pit 1, and for the intrusion of a large amount of water such as torrential rain, the water in the pit 1 The configuration is such that the accumulation gate 3 is raised.

Next, as shown in FIG. 3, a protection plate 9 is provided along the opening groove 4 opened on the floor surface C. The protection plate 9 is a mechanism in which two plates are connected by a pivot 10. The pivot 10 is placed along the opening groove 4.

Therefore, as shown in FIG. 4, when the gate 3 rises above the opening groove 4, the protective plate 9 is pushed up to form a mountain with the pivot 10 as a center. At this time, it is possible to pass through the gate 3 without damaging the gate 3 when the vehicle enters.

Further, as shown in FIG. 5, when the gate 3 is raised, the protection plate 9 is pushed upward, so that the vehicle cannot pass. As described above, the protective plate 9 has a mechanism for covering the opening groove 4 and preventing the gate 3 from being damaged due to vehicle entry.

The float 2 is formed by covering styrofoam with a synthetic resin material, or, as shown in FIG. 6, by covering the styrofoam plate 11 with a reinforced resin material 12 in order to make the gate 3 itself a buoyant body. It can also be. Further, in addition to the above-mentioned styrene foam, air or gas may be injected into the gate to make the gate itself a buoyant body, and a mechanism most suitable for the situation is adopted. . Further, it is desirable that a filter be attached to the water inlet 6 to prevent the inflow of dust.

In the present invention having the above structure, as shown in FIG. 7, the water level of the water overflowing on the road due to the concentrated torrential rain and the like rises, and the water level of the water a flowing into the pit 1 from the water inlet 6 rises. Accordingly, the gate 3 is raised.

Further, as shown in FIG. 8, after filling the pit 1, the water a 'rising from the floor C and flowing into the facility is blocked by the gate 3 between the entrances B. Will be.

Next, as shown in FIG. 9, when the water overflowing on the road is drawn and there is no risk of water intrusion, the water in the pit 1 is extracted by a pump or the like, and the gate 3 is lowered to enter the entrance. Release B.

As shown in FIG. 10, in the pit 1 provided with the drainage structure 8, if the amount of water a flowing into the pit 1 from the water inlet 6 is larger than the amount of water b drained, And the pit 1 is filled with water and the gate 3 is raised as the water level rises.

Further, as shown in FIG. 11, after the inside of the pit 1 is full, the water a 'rising from the floor C and flowing into the facility is blocked by the gate 3 between the entrances B. Will be.

Next, as shown in FIG. 12, when the water overflowing on the road is drawn and there is no danger of the water entering, the drain 8
The water in the pit 1 is naturally discharged, and the gate 3 is lowered to release the entrance B.

[0024]

As described above, according to the present invention, there is provided a mechanism for closing a doorway by raising the gate by using the buoyancy of the inflowing water to prevent the inundation of the water caused by the torrential rain or the collapse of the river. By doing so, it is possible to prevent water from entering the facility without requiring any manual operation or mechanical operation. In addition, there is no danger of flooding in a pit with a drainage function, and when the water level drops, the water in the pit is naturally drained, and the gate can be stored in the pit, requiring absolute manual operation. And not.
