Description

  The present invention blocks the entry of water from the normal entrance / exit of underground parking lots / entrances / underground road entrances / openings at the time of flood damage such as underfloor / floor inundation / road inundation, etc. The present invention relates to an inundation prevention device for preventing the destruction of electrical facilities and computer facilities that have been used and for ensuring the survival of human lives.

  Conventionally, most of the flood damages that are positioned as natural disasters are manually piled up to prevent water from entering when they occur. In some areas where the sea level is zero, hydraulic sluice gates may be installed using steel plates. In addition, since the cost is expensive, the current situation is that only shutter facilities for preventing intruders in crime prevention are usually installed. However, sandbags and shutters cannot completely prevent the ingress of water currents.

  Therefore, as shown in Patent Document 1, simply installing a simple device at a normal entrance / exit of an underground parking lot entrance / exit opening / subway entrance / exit opening of an area where flooding can be predicted, In order to completely block the entry, each opening is embedded with a bellows-type water tank made of “pressure-resistant waterproof fiber” commonly used for fire fighting hoses, etc. The thing which was made to intercept is considered.

According to this, by supplying a high-pressure water flow such as a fire-fighting faucet and a fire-fighting faucet to the bellows-type water tank, the water tank expands and extends upward, so that an arbitrary height can be secured. Since the water tank is formed of a flexible pressure-resistant waterproof fiber, the opening can be sealed with water pressure.

  However, this is only a bellows shape so that the whole forms one water tank and can be expanded and contracted from a compactly folded state, and the inner space is a large space. For this reason, when a high-pressure water flow is introduced, the water tank easily expands not only in the upper direction but also in the lateral direction, and not only the upward extension rate is bad, but also the shape tends to collapse and the strength against water immersion remains insufficient.

  An object of the present invention is to provide a new inundation prevention device that improves on these points.

In order to achieve the above-mentioned object, the present invention faces a bellows type water tank in which a plurality of water packs are connected in series to an opening of a structure that needs to prevent water infiltration before introducing hydraulic fluid into each water pack. Store in the part retracted from the reference surface set for the part, open the opening, expand when hydraulic fluid is introduced into each water pack, let it protrude from the reference surface, make a wall shape and seal the opening The water pack is configured so that both ends of each water pack are movably inserted into a rail groove of a guide member having an inwardly opened box formed at a portion facing the side edge of the opening. And the inner surface of the rail groove when inflated to seal the opening, and a partition is provided between the water packs adjacent to each other above the lowermost water pack, and the partition Lower water Characterized in that the click is constructed as equally in hydraulic fluid in the upper side of the water pack is provided hydraulic fluid flow port as fed.

  In this way, instead of making one large tank inside the bellows into a bellows shape, a plurality of small water packs inside the sky are arranged in a bellows shape to form a bellows type water tank, so that the expansion is made in units of water packs. An appropriate expanded state can be realized for each individual water pack. Therefore, it is possible to form a suitable wall with strength by securely inflating in the protruding direction and suppressing deformation in the lateral direction as compared with the conventional one in which the entire inner space forms a large space. .

In order to perform the expansion operation and the sealing operation more appropriately, both ends of each water pack are movably inserted into the rail groove formed in the part facing the side edge of the opening, and when expanded, the inner surface of the rail groove is expanded. The openings are configured to be in close contact with each other.

As a specific embodiment , a partition is provided between each water pack sequentially adjacent above the water pack positioned at the lowermost stage, and these partition walls are sequentially and evenly distributed from the lower water pack to the upper water pack. A hydraulic fluid circulation port is provided so that the hydraulic fluid is fed.

To more accurately prevent the deformation of the lateral, bellows-type water tank, intermittently in a direction in which the bellows type water tank is pushed out, causes incidental the reinforcing wire member extending in a direction perpendicular to the same direction, the reinforcing wire It is preferable that both ends of the guide member are accommodated inside the side wall of the guide member except for the lowermost reinforcing wire .

  In order to perform the expansion operation more appropriately, a lid member is disposed further on the distal end side of the water pack located at the distal end, and both ends of the lid member are engaged with the rail groove via the follower. It is done.

  Since the present invention is configured as described above, it is possible to provide a novel and useful inundation prevention device that more effectively exhibits the inundation prevention effect.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the inundation preventing device of this embodiment has a structure in which a bellows-type water tank 2 formed by connecting a plurality of water packs 1 in series is required to prevent inundation before introducing hydraulic fluid into each water pack 1. Stored in a part retracted from a reference surface 32 such as a floor surface or a ground surface set at a part facing the opening 31 (see FIG. 2) of the object 3, the opening 31 was opened, and the working fluid was introduced into each water pack 1. In this case, as shown in FIG. 3, it is inflated so as to protrude from the reference surface 32, and is configured to form a wall surface and seal the opening 31.

  The structure 3 is, for example, a building, an underground parking lot, an underground road, a subway, or the like, and forms a storage space 33 as shown in FIG. 4 by digging down the reference plane 32 facing the opening 31 located at the entrance. The storage space 33 includes a main storage portion 33a for installing the main body frame 4 for storing the bellows-type water tank 2, and an auxiliary storage portion 33b for securing a water supply / drainage channel and facilitating maintenance of the bellows-type water tank. It is composed of

  The main body frame 4 has a long rectangular parallelepiped shape having an inner space for storing the bellows-type water tank 2 in a contracted state substantially completely. Is provided. And this collar 41 is latched to the step part 33c (refer FIG. 5, FIG. 6) formed in the corresponding | compatible part of the upper edge of the main storage part 33a and the auxiliary storage part 33b. The auxiliary storage portion 33b is provided in a state where the side surface 4a and the bottom surface 4b of the main body frame 4 are released in a portion continuous with the main storage portion 32a, and the lid 34 shown in FIG. I try to install it as possible.

  And the guide member 5 which makes the box shape open | released inward is attached to the site | part which faces the side edge 31a of the opening 31 shown in FIG. 2, ie, the inner surface 4c of the both ends of the longitudinal direction of the said body frame 4 in the standing state. Rail grooves 51 are formed.

  Each water pack 1 is made of an appropriate material having flexibility and pressure-proof / waterproof function, such as “pressure-resistant / waterproof fiber” commonly used for fire hoses, etc., and rubber generally used for rubber boats, etc. Thus, as shown in FIG. 1 and the like, it is sewn into a substantially rectangular parallelepiped shape. The bottom end of the water pack 1L positioned at the bottom end, that is, the lowermost stage, is provided with a supply / discharge port 11 that functions as a hydraulic fluid injection port, and a partition wall 1M positioned between the adjacent water packs 1 and 1 sequentially above it. Is provided with a working fluid circulation port 12 for communicating the inner space of both water packs 1, 1, and the working fluid injected from the working fluid supply / discharge port 11 is passed through these working fluid circulation ports 12 to the upper water pack 1. Are sent evenly in order. In the illustrated example, the hydraulic fluid circulation ports 12 are provided in a zigzag shape upward in the central portion of the water pack 1, and are provided in a straight line upward in the portion where both ends 1a of the water pack 1 are bulged. It is. However, it may be provided in any manner as long as the hydraulic fluid is fed sequentially and evenly from the lower water pack 1 to the upper water pack 1. The water packs 1 and 1 share the partition wall 1M or are connected by appropriate means in the partition wall 1M.

  Each water pack 1 has both ends 1a movably inserted into the rail groove 51 as shown in FIGS. 2 to 4 and the like, and moves while being guided in the vertical direction along the rail groove 51 during expansion and contraction. When water pressure is received from the outside, the opening 31 is sealed in close contact with the inner surface of the rail groove 51.

  The bellows-type water tank 2 comprises the water pack 1 and a lid member 21 provided on the distal end side of the water pack 1H located at the distal end, and both ends 21a of the lid member 21 are connected via a follower 6. The rail groove 51 is engaged with the side edge (that is, the side wall of the guide member 5). Of course, the follower 6 may be provided in the rail groove 51 (inside the side wall of the guide member 5) or outside the rail groove 51 (outside of the side wall of the guide member 5). The bellows type water tank 2 is embedded in the auxiliary storage space 33b together with the water supply / drainage system 13 (see FIG. 5) connected to the hydraulic fluid supply / discharge port 11. The hydraulic fluid supply / discharge port 11 and the water supply / drainage system 13 do not impede not only the mode of being provided on the lower surface side of the lowermost water pack 1L as in the illustrated example, but also the mode of being provided on the side surface. The bellows-type water tank 2 is accompanied by a reinforcing wire (aggregate) 22 extending in the direction (lateral direction) perpendicular to the direction in which the whole protrudes (upward direction), that is, in the longitudinal direction. The reinforcing wire 22 is accommodated in a bag body 22a as shown in FIGS. 6 and 7, etc., and the bag body 22a is connected to the partition wall 1M via a flange 22b, and both ends thereof are the lowermost reinforcing wire material 22. Except in the rail groove 51 (that is, inside the side wall of the guide member 5).

  The inundation prevention apparatus of this embodiment configured as described above has a high-pressure water flow such as a fire faucet, firefighting faucet, indoor water supply pipe, tap water, etc. to each water pack 1 through the hydraulic fluid supply / discharge port 11 when a flood occurs. Each water pack 1 expands as shown in FIG. 3 and FIG. 6 from the contracted state shown in FIG. 2 and FIG. 5 by accelerating the water from the contracted state shown in FIG. 2 and FIG. Arbitrary height can be ensured by extending the entire formula water tank 2 and controlling the amount of water supply. Since the water pack 1 is formed of a flexible pressure-resistant waterproof fiber, the water pressure antagonizes the surrounding water W (see FIG. 6) due to water immersion and is pressed against one inner surface of the rail groove 51 by the pressure of the water W. As a result, the sealing effect is exhibited. Further, when stored, the hydraulic fluid supply / discharge port 11 functions as a hydraulic fluid drainage port, and the hydraulic fluid that has moved to the lowermost water pack through the hydraulic fluid circulation port 12 is drained from the hydraulic fluid supply / exhaust port 11 to be bellows. The water tank 2 contracts. Drainage can be performed by using an artificial operation force or a pump. The hydraulic fluid supply / exhaust ports 11 are provided in pairs. In addition to a mode in which hydraulic fluid is introduced from both hydraulic fluid supply / discharge ports 11 during supply and drained from both hydraulic fluid supply ports 11 during drainage, one operation is performed during supply. The present invention can also be implemented by a mode in which hydraulic fluid is introduced from the liquid supply / discharge port 11 and drained from the other hydraulic fluid supply port 11 during drainage.

  Normally, the inundation prevention device is stored inside the reference surface 32, and the lid member 21 is substantially flush with the reference surface 32 as shown in FIGS. . Since the guide member 5 is also embedded and attached to the wall surface facing the opening 31, the opening 31 is not narrowed and does not hinder traffic. In operation, the accordion-type water tank 1 extends as shown in FIGS. 3 and 6 by sealing water from one or both of the hydraulic fluid supply and discharge ports 11 using fire hydrant water and the like, and closes the opening 31. It is possible to completely block water from the outside to the inside. When unattended at night, etc., when danger can be predicted, unmanned water supply by a remote controller or a microcomputer can be performed using a valve actuator or the like. As a result, it is possible to completely protect, for example, machinery, electricity, computer equipment, vehicles, etc. installed underground from flood damage.

  And this embodiment did not make one large water tank of the inner space bellows-like, but constituted the bellows-type water tank 3 by arranging a plurality of small water packs 1 having a small inner space in the shape of bellows. It is made for each water pack 1 and an appropriate inflated state can be realized for each individual water pack 1. Therefore, it can be surely expanded in the protruding direction compared to the conventional one in which the entire inner space forms a large space, and at the same time, it prevents the lateral deformation of the shape and forms an appropriate water wall with strength. It becomes possible.

  In particular, both ends 1a of each water pack 1 are movably inserted into a rail groove 51 formed at a portion facing the side edge 31a of the opening 31, and are in close contact with the inner surface of the rail groove 51 when expanded. Therefore, the expansion operation and the sealing operation can be appropriately performed.

  Specifically, since the hydraulic fluid supply / exhaust port 11 is provided in the water pack 1L located at the base end, and the hydraulic fluid circulation port 12 that communicates the inner space between the adjacent water packs 1 and 1 is provided, The working fluid can be suitably fed into each water pack 1 without impairing the liquid tightness of the entire bellows type water tank 2.

  In particular, the bellows-type water tank 2 is supplemented with a reinforcing wire 22 extending in the horizontal direction perpendicular to the upper direction where it protrudes. Further, it is possible to more effectively ensure the upward extension operation and the appropriate wall strength.

  In particular, since the lid member 21 is disposed further on the distal end side of the water pack 1H located at the distal end, and both ends 21a of the lid member 21 are engaged with the rail groove 51 via the follower 6, along the rail groove 51. Thus, the expansion operation of the entire bellows-type water tank 1 can be performed more appropriately.

  The specific configuration of each unit is not limited to the above-described embodiment. For example, at the time of operation, a lightweight H-shaped reinforcing guide made of aluminum or the like designed in advance at an arbitrary interval may be erected so as to be in contact with both side surfaces of the bellows type water tank 2. It is desirable that the aluminum H-shaped reinforcing guide has a weight that can be manually installed and is stored in the rail groove 51 in a normal state. Moreover, you may install the hydraulic-fluid supply / discharge port 11 in the upper surface of the ground.

  Other configurations can be variously modified without departing from the spirit of the present invention.
