Description

The present invention relates to a device measure for preventing water from infiltrating an existing house due to heavy rain or the like.

In recent years, due to abnormal weather, heavy rains and rivers have been flooded one after another. Due to the large amount of precipitation and the flooding of the river due to the large amount of precipitation, the water volume increases and the mud on the embankment mixes with the flooding of the sewer and septic tank river to form sewage, and the gap between the basic air supply port and the hinged door and the door frame. Sewage infiltrates from underfloor, polluting the floor surface, interior walls, household goods, furniture, etc., and suffering great damage.

However, in recent years, a water stop device that raises and lowers manually or automatically has been developed in buildings that do not have a basic air supply port and in the opening of an underpass, and an invention has been made that can stop water when the water level rises. There was an air opening, and there was a drawback that it was not possible to prevent the ingress of water from the basic air supply port and it was not possible to prevent the ingress of water in ordinary houses.

To solve this drawback, there is an option to block the basic air supply port, but it is not suitable for existing houses because it has the role of drying the humidity under the floor and is used for humidity control inside the house.

As a remedy for this, sandbags were usually piled up around the dwelling to deal with flood damage caused by underfloor flooding, but sandbags are limited to the area around the entrance and cannot deal with the ventilation openings of the housing foundation. The present invention provides a ventilation port inundation prevention device that can block the underfloor ventilation port. There is a door body 4 in the device, and the pressure of the water flowing into the device and the buoyancy material 8 lift up and close the ventilation port. The closed door body 4 is said to have two structures of a close contact seal 2 and a close contact seal 5 by water pressure, a close contact seal 2 by water pressure, a close contact seal 5, an expansion seal 6 by water pressure, and a seal pipe 3 to completely stop the inflow of water. However, in this method, the size of the ventilation opening such as a mouse and the fence that prevents the invasion of the mouse and the like are harmful, and further, the sandbags are piled up at the entrance and the like, which imposes a burden on the resident and becomes complicated.

The problem to be solved is that the size of the ventilation port, the so-called basic air supply port, is different, and it is necessary to build it according to the size of the basic air supply port in order to install it, and the opening such as the entrance. Has the problem that it requires the labor of manually stacking sandbags.

The most important feature of the present invention is to block the ingress of water such as sewage into the basic air supply port and the opening such as the entrance door without being forced by human power.

The inundation prevention device of the present invention is a floating body of a floating air compressor switch insertion device provided below the basic air supply port by a high-pressure air compressor having a Pa of 2 k or more, a floating air compressor switch insertion device, and a silicon rubber bag. When the water rises, the tip of the floating body pushes the metal ball for sealing the air compressor with the switch of the printed circuit board for operating the air compressor provided on the upper part of the floating air compressor switch insertion device. Switch on and operate. Similar to the silicone rubber bag provided in the basic air supply port and the basic air supply port provided in the door frame, air is pumped from the air compressor to the silicone rubber bag at once, and the silicone rubber bag expands to drain water such as sewage. It has the effect of preventing intrusion into the house.

Since the high-pressure air compressor 25 of 2 kPa or more and the floating body 2 of the floating switch insertion device that operates the compressor are installed in the lower part outside the basic air supply port, the floating switch insertion device is always subject to external temperature, dust, small insects, etc. Since the relay 6 and its switch 8 may cause corrosion due to salt damage or the like, a sealing metal ball 5 is sealed under the switch 8 provided on the relay 6 for operating the air compressor 25 at the upper part. Has been done. Before the water level tries to enter the basic air supply port frame 19, the upper tip 4 of the floating body 2 rises at the water level, pushes in the sealing metal ball, and the switch 5 for operating the air compressor 25 is turned on and the air compressor 25 is turned on at once. More air is pumped and the silicone rubber bag provided at the basic air supply port and the silicone rubber bag provided at the door frame are expanded to prevent water such as sewage from entering the room.

FIG. 1 is a transmission cross-sectional view of the floating switch insertion device of the device of the present invention, in which the housing 1 of the device, the floating body 2, the partition plate 3 for stably raising the floating body 2, and the upper portion of the partition plate 3 are shown. Is a metal ball 5 for sealing, and a switch 5 on the upper part of the relay 6 and the switch 5, the relay 6 and the wiring 14 are a resin cutting block 7 and the block that prevent insects such as salt damage, dust, and ants from invading. A sealing metal ball 5 is built in and protected in the tapered shape provided inside.
FIG. 2 is the same from 1 to 14, but when the water volume such as sewage rises due to heavy rain or river flooding, and when the water level of the floating body 2 rises, the sealing metal ball 5 is attached to the upper end portion 4 of the floating body 2. Conducts to the relay 6 from the switch 5 built in the push-in cutting block to operate the air compressor 25.

3 and 4 show the silicon rubber bag 17 provided on the door frames 15 and 15a of the entrance door through the door frame 15. The floating body 2 is pushed up by water such as sewage that has risen, the upper end 4 of the floating body pushes up the metal ball 5 for sealing, and the air compressor 25 is provided in the door frame of the opening of the entrance door by the switch 5 of the relay 6. It is connected to the body 2 with a pressure resistant hose.
When water enters the room during flooding, the floating body 2 of the inundation prevention device rises, the upper end 4 of the floating body rises, the metal ball 5 for sealing is pushed in, and the switch 5 of the relay 6 is pushed to press the air compressor 25. It is operated to inflate the silicon rubber bag body 17, and the silicon rubber bag body 17b expands to prevent the ingress of water such as sewage.

According to FIG. 5, when the water level rises, the floating body 2 rises due to the buoyancy of the water to operate the air compressor 25, and the silicon rubber bag body 21 provided on the basic air supply port frame 20 attached to the air supply port 19 of the foundation 24 has an upper end. As mentioned above, the air compressor 25 is operated at once, the air is pumped, the silicone rubber bag body 21c expands, and the sewage that is about to enter the house is blocked, and the underfloor, floor surface, household goods, furniture, etc. of the house are removed. It provides an inundation prevention device that facilitates protection from inundated sewage. The pressure resistant hose 22 is connected to the air compressor 25.

In order to install and use the present invention, maintenance such as the silicon rubber bag body 3 provided on the basic air supply port frame, the silicon rubber bag body 2 provided on the door frame, and the air compressor 4 is required on a regular basis.

In addition, as the structure of an existing house, there is a gap between the foundation and the periphery of the building, and the gap must be waterproofed with a viscous epoxy resin or the like at the same time.

However, some modern houses have no gap between the foundation and the building, so in this case, it is not necessary to apply waterproof treatment with viscous epoxy resin or the like at the same time.

Further, the door frame needs to be replaced with the door frame of the present invention.

When sewage is inundated due to flooding of sewage due to flooding of rivers due to heavy rain in ordinary houses The present invention prevents the ingress of sewage, but is used for structures such as the opening of a convenience store, the entrance of an apartment house, and a carport. Can also be applied to.
