Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to residential buildings, mechanical rooms of buildings, unmanned substations and other electrical rooms, test rooms with precision equipment, ship hatches, etc. due to flooding or accidents. This relates to automatic flood protection equipment that prevents major flood damage.

[Prior art] Many technologies have been quantified to attach flexible bags that are inflated by fluid to riverbeds to dam running water or adjust the water level. Examples of special improvements in the case of using a water stop weir include a "water stop weir" (Japanese Utility Model Publication No. 55-88431) and a "rubber weir" (Utility Model Publication No. 56-8621).

Among these, the "water stop weir" is a combination of a flexible airtight bag 3' and a rigid plate-like body, as shown in the cross-sectional view of Figure 8, and is attached to the river bed, depending on the degree of expansion of the bag. damming up running water or allowing it to overflow.

This invention states that because it has such a structure and function, it was able to move upstream, which had previously been considered a problem with this type of 7iiJ river weir.

In addition, "rubber weir" has at least one partition plate integrally formed within the expansion bag body, and even if at least one part is damaged, the weir height can be secured by filling the other air chamber with fluid. states that it can be done.

[Problem that the invention seeks to solve]

The above-mentioned prior art, which further improves the idea of applying a flexible bag to a river base, has a special purpose when used in rivers. The purpose of the invention is to improve the damage and wear of the bag due to contaminants in flowing water at point J.

The idea of applying a flexible bag as a flood protection device to prevent damage caused by floods and accidents to houses, mechanical rooms, electrical rooms, etc. is itself a new attempt, but it is difficult to turn this new idea into reality. When implementing 6D, 1. It is difficult to solve separate and distinct problems.

Damage caused by floods and accidents can lead to irreparable damage once water is allowed to flood into buildings such as houses, building mechanical rooms, computer rooms, unmanned substations, and resource rooms. Therefore, the expansion of the bag body must be ensured and the operation L5 must be performed quickly, and the possibility of water intrusion must be detected with certainty. Because the buildings in question are often uninhabited despite having valuable internal components, automatic activation means must be provided.

The present invention utilizes a flexible bag as a waterproof bag for buildings, etc. for the first time, solves the technical problems associated with this use, and provides a new automatic waterproofing device that can guarantee reliable waterproofing effects. This is the object of the invention.

[Means for solving problems]

The automatic flood protection device according to the present invention includes a storage box with a lid that is buried under the road surface over almost the entire width of a flood channel passage, a bag body made of a flexible membrane stored in the storage box, and this bag body. The above-mentioned problems have been solved by providing a filling means for expanding and stopping water on the road surface within a short time, and a water intrusion detection means for commanding the operation of the filling means.

Further, to explain this configuration based on an embodiment of the present invention, in FIG. 1, 1 is a storage box, and 2 is a fluid in this storage box, which usually serves as a step board. 3 is a flexible bag which is housed in the storage box 1 and can be inflated when filled with air.

Reference numeral 4 denotes a filling means for inflating the bag 3 within a short period of time, and in this example, a cylinder is shown. Reference numeral 5 denotes a means for detecting the fact of flooding when commanding the operation of the filling means, and in this example, an electrode sensor is shown.

[Effect]

Since the present invention has the above-described configuration, the bag 3 is normally stored in the storage box 1 in a folded state, and the box is buried in the entrance passage of a building with the lid 2 on top. In this case, the storage box 1 spans almost the entire width of the passageway, but since it is buried under the road surface, it does not pose any problem for the passage of traffic or the transportation of handcarts, etc. (Figures 2 and 3) .

Once water approaches the passage due to a natural disaster such as a flood,
The detection means detects water intrusion and issues a signal, and in response to this, the filling means operates to inflate the bag body 3 within a short time. This action causes the lid 2 to spring up, protecting the bag from damage caused by obstacles such as driftwood (FIGS. 1 and 4).

〔Example〕

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 7.

The storage box I has a welded steel plate structure, and the lid 2 needs to have sufficient load resistance because people, cars, etc. will pass through it. In this example, a polycoated plate was used, but of course a metal plate may also be used. At the location where the storage box 1 is buried in the entrance/exit passage of the building,
Two strip-like skin plates 6 are attached to protrude from both sides of the storage box (FIGS. 2 and 3). After the storage box 1 is buried under the surface of a desired passageway, this skin plate 6 is water-sealed by filling the portion in contact with the wall of the building with mortar. In this example, the skin plate 6 is made of stainless steel strip with a smooth surface and is attached to the wall surface up to the water stop height.

Installation of the storage box 1 of the lid body 2 (J is a bag made of a fabric material that is easy to open and close, and made of a polymeric material, such as non-breathable cloth treated with rubber, and connected to the air supply lower and exhaust gas. Mouth 8
and a safety valve 9.

In this example, the rubberized cloth that is the material is F'J' plain weave nylon cloth using 84r) denier yarn with 27mm each in the vertical and horizontal directions.
The fins were topped with chloroprene rubber so that the X-shape was 0.8 fins. As shown in Fig. 5, the bag made of this material has a partition wall 10 installed inside and has three air chambers (
3A, 3B, 3C), and the air supply lower is attached to the central air chamber 3B, and the air chambers 3A and 3C on both sides are provided with vents 11.11 in the partition walls 10.10 inside the bag.
The central air chamber 3B was once started to expand, and then the air chambers 3A and 3C on both sides were expanded. Furthermore, the exhaust port 8 is also attached to the central air chamber 3B. The safety valve 9 is installed to prevent danger in case the internal pressure rises more than necessary. The pressure resistance of the bag is theoretically -1, 0 for a water depth of 1 ril, and 1. kg/Cl11, but in practice it is desirable to plan the strength of the bag material to be between 1.5 and 3 times that amount.

When the bag body 3 is inflated, there is a reliable water source with the passage side wall.
This is an important problem when applying a flexible bag for purposes such as the present invention. This is because the purpose of the invention is different from the prior art, which simply shuts off water at a rough level to adjust the water level of a river.

In Fig. 1, as mentioned above, a skin plate 6 is erected on the side of the storage box 1 at the place where it contacts the entrance/exit passage, and the wall surface is covered with mortar. In order to achieve close contact with the bag body 3, a flat belt-shaped backing 14 is attached to the outer surface of the bag body 3 at the maximum bulging diameter portion. The material is chloroprene rubber, which has a JIS A hardness of 40 to 50 degrees and is soft enough to meet the water sealing purpose. In general, materials that are soft, have excellent aging resistance, and swell when exposed to water are highly recommended.

Next, when the bag body 3 is inflated, the outer shape becomes rounded and the water-stopping power of a part of the bottom corner of the bag tends to be incomplete, so a structure is required to reinforce the water-stopping power of this part. 6 and 7 are drawings showing an example of a water seal according to the present invention. FIG. 6 is a front sectional view, and FIG. 7 is a side sectional view showing the water seal state of the bottom of the bag body. In both figures, a fixing tape 13 and a backing 14 are attached to the surface in contact with the bottom of the storage box 1, and a metal plate [5] is attached to the opposite side of the storage box, and the side wall of the storage box 1 is secured with bolts using a pad 15'. Attach the fixing tape 13 and the backing 14 to the side that contacts the storage box, and attach the skin plate 6 to the opposite side of the storage box.
Therefore, it is fastened with bolts.

Three belts 16 shown in FIG. 4 are attached to prevent the bag 3 from separating from the storage box 1 when it is inflated. The material of the fixing belt is commercially available plain-woven polyester cloth, the middle part is joined to the bag body 3, the lower end is joined to the storage box,
The upper end is joined to the inner surface of the lid body 2. In order to join the fixing tape 16 to the bag body 3, simultaneous vulcanization and adhesion was performed at the time of molding the bag body, but it may also be bonded or sewn after molding. In this example, a gas cylinder 4 is used as a pressure medium as a filling means,
An electromagnetic valve opener 17 is connected as a member for introducing this atmospheric pressure into the bag body 3. High-pressure cylinders for gases such as nitrogen and carbon dioxide are stored in a storage box 1 side by side with a bag 3 as shown in FIG. Of course, it is possible to arrange it independently outside the storage box 1, and there are no restrictions on the type of gas inside the cylinder. The gas pressure in the cylinder is determined by JIS according to the type of gas, and is 100 to 1.
A commercial standard of 50 kg/cJ is available. Also, a commercially available electromagnetic valve opener that opens the valve by inputting a signal can be used.

In this embodiment, an electrode type sensor 5 is used as the detection means. In other words, this sensor 5 consists of a cylindrical outer case and a stainless steel electric scraper attached to the inside. When the installed location is flooded and the electrode comes into contact with liquid, the electrode and the outer case become electrically connected. The signal is input to the control panel 18. The control panel 18 has a built-in management function that controls the system of 4B-C of the present invention, and upon receiving the input signal, immediately commands the cardiomagnetic valve opener 1-I' to open the valve. Operation is 1':.

Therefore, the gas inside the gas cylinder 14 is depressurized through the air supply lower of the flexible bag 3 and is inflated by being ejected and filled within a very short time.

The control panel 18 is provided with a switch for an alarm buzzer, an automatic/manual changeover switch for the electromagnetic valve interrupter 17, and a circuit for reporting to a remote location. This is because it is necessary to periodically inspect the device and to notify the central control room when the automatic flood protection device of the present invention is installed in an unmanned room such as a basement. Furthermore, since it is expected that troubles such as power outages will often occur during floods, an emergency backup power supply device is installed and incorporated into the control panel 18, and wiring is made so that the power source can be automatically switched to this power source in the event of a power outage.

〔Effect of the invention〕

Since the present invention produces the above-mentioned effects, it is possible to completely prevent water from flooding into buildings, which is the original purpose, and protect valuable built-in items from water damage. Therefore, in the past, it was difficult to store valuables in basements due to the risk of flooding, but with the equipment of the present invention, is this concern resolved? T! I'm Renoko.

Since the flexible bag of the present invention is made of a deformable material, it is highly reliable and waterproof.

In addition, when the bag is stored and closed, a passageway 1■7. It does not interfere at all.

As an effect specific to the embodiment, the bag body 3 has three air chambers (3A, 3B).
, 3C), and connect the air supply lower and exhaust port 8 to the central air chamber 3.
By attaching it to B and connecting the three air chambers through the vent 11, the device operation starts from 3B and extends to both chambers, but when exhausting air, it starts from the center 3B and starts to contract first, then both sides. After using it once, it can be easily stored again in a narrow storage box.
