Description

  The present invention relates to a tsunami countermeasure device.

  The following tsunami evacuation devices have been proposed prior to the recent tsunami attack of the Great East Japan Earthquake.

  JP2008-14112

According to the tsunami evacuation device disclosed in Patent Document 1, neighboring residents can escape from the tsunami by going up the stairs and evacuating to the evacuation stage. However, as seen in the previous earthquake disaster, The reality is that in some cases, they were swept away without being able to evacuate. These aircraft are very expensive, the amount of damage is significant, and it takes a lot of time to restart. In particular, helicopters and Cessna aircraft are necessary for emergency rescue and information gathering in the event of a disaster, so it is necessary to protect them reliably from tsunamis and floods.
Therefore, the present inventor has previously created and proposed a tsunami countermeasure device having means for receiving an aircraft waiting on a specific part of an airfield from below and means for lifting and holding the receiving means.
Specifically, an elevating frame (equipped with a drive means with a parallel crank type lifter that folds an X-shaped link into a pit formed in a part of the base and guides the upper and lower ends, and attached to the upper end ( The means for receiving is hermetically sealed at the upper end opening of the pit so as to be flush with the base. While helicopters and other aircraft are kept on standby during normal times, if an evacuation warning for a tsunami strike is issued after an earthquake, the aircraft is assumed to be tsunami by extending the X-shaped link and lifting the lifting frame It can be evacuated (evacuated) to a safe place higher than the height. As a driving method, a ball nut / screw shaft type cylinder or the like is disclosed.
According to such a lifting type tsunami countermeasure device, the aircraft can be evacuated highly, so the aircraft can be safely protected from the tsunami, but in reality, these aircraft are stably waiting on the lifting frame. Rather than being supported on the lifting frame via three or more wheels provided at the bottom of the aircraft, it is very unstable, and if a large earthquake occurs, its vibration Acts on the aircraft and assists in the bounce action of the air-filled wheels, causing rollover and rollover, and even when lifted on a lifter to cope with the tsunami attack, the impact load caused by the tsunami drifting material is lifted There was a risk that the aircraft above would fall or fall off.

  The present invention is intended to solve such a problem, and provides a tsunami countermeasure device that stably and reliably protects an object such as an ascended evacuated aircraft so as to maintain a regular evacuation state against an tsunami attack. For the purpose.

  In order to achieve the above object, the invention according to claim 1 is characterized in that means for receiving an object having wheels, such as an aircraft or a related vehicle, waiting at a specific part of an airfield from below, and raising the means for receiving the object are raised. A tsunami countermeasure device having a holding means for holding the normal posture of an object such as an aircraft at a normal position.

  As described above, the present invention is a tsunami countermeasure device having means for receiving an object having wheels, such as an aircraft or a related vehicle, waiting on a specific part of an airfield from below, and means for lifting and holding the receiving means. Since it is equipped with posture holding means to keep its normal posture in the normal position with respect to objects such as aircraft, it keeps the normal evacuation state against the tsunami attack of the aircraft evacuated ascending It is possible to provide a tsunami countermeasure device capable of protecting as stably as possible.

  10 to 14 show another embodiment. This embodiment has the same purpose as described above, and pipe piles 43 are embedded and fixed at appropriate locations (three locations corresponding to the wheels 42 of the aircraft 41) on the base 40 that is a part of the airfield including the hangar, A hydraulic drive cylinder (drive means) 44 is provided in which the rod extends vertically upward through the inside. The pipe piles 43 are connected to each other by an underground connecting beam 45, and a fixed seat 46 is fixed to a surface portion of the base 40 corresponding to the periphery of the drive cylinder 44.

  On the other hand, a conical frame receiving seat 48 that fits into the fixed receiving seat 46 when lowered is attached to the upper end of the drive cylinder 44, and the hollow frame main body 49... Is attached. The drive cylinder 44 and the like constitute means for lifting and holding, while the plurality of frame main bodies 49 are connected together by connecting beams 50 as shown in FIG. 10 to form one lifting frame (means for receiving the aircraft from below) 51. Is configured. The drive cylinder 44 and the lifting frame 51 constitute a lifter 52. In addition, you may form the raising / lowering frame 51 by one saucer type | mold flame | frame as mentioned above.

  The lifter 52 is easily lowered when the drive cylinder 44... Is moved up synchronously at the time of warning of the tsunami strike and the lift frame 51 is raised higher than the tsunami expected height and hydraulically locked. In this case, the frame main body 49 of the elevating frame 51 is equipped with posture holding means 54 to hold the wheel 42 from the front and rear as shown in FIG. By doing so, the aircraft 41 is prevented from being blinded or tilted by an external load between the earthquake and the tsunami.

This posture holding means 54 is provided with a pair of openings opened in front of and behind each wheel 42 via a hinge 55, which can be freely tilted and tilted, and when there is an earthquake alarm. Alternatively, when the subsequent tsunami strike alarm is issued, the raising and lowering drive units 57 and 57 are started so that the front and rear wheel sandwiching plates 56 and 56 stand up and sandwich the wheel 42 as shown in FIG. It is. The wheel holding plate 56 includes a crank c and is connected to a rod of the raising / lowering drive unit 57.

If a pre-capturing device 64 such as a wire rope / link chain is provided, the lifter 63 is protected from drifting objects when a tsunami X strikes, and the aircraft 66 held by the posture holding means 65 is more reliably and stably held. Will be able to.
The preliminary capturing device 64 may be a net-like device as shown in FIGS.

  18 and 19 show another embodiment. In this embodiment, a pit 72 is formed in a hangar 71 that stores an aircraft 70 such as a fighter aircraft in standby, and an X-shaped link 73, a drive cylinder 74, and a lift frame 75 are provided so as to be able to be lifted and lowered. The lift frame 75 is installed as a lifter that can be moved up and down by a drive cylinder that can be driven vertically, and the lifter 76 can lift and evacuate the aircraft 70. In particular, the width direction of the aircraft 70 in the hangar 71 A pair of elevating guide rails 78 is fixed to the opposing surfaces corresponding to each other in the vertical direction, and rollers 79 are provided along these elevating guide rails 78 to move up and down synchronously by an electric motor and an interlocking shaft. A catching hand that is a net such as a coarse net that extends in a plane with these rollers 79 as four-point support. 80 so as to extend upward region over a wide range including both aircraft 70, 70 on the lifter 76 and stretched.

  The lifter 76 stands by in a reduced state in the pit 72 as shown by the phantom line in FIG. 18 during normal times. However, the lifter 76 starts and expands greatly based on an emergency earthquake warning or a subsequent tsunami strike warning, and passes through the lifting frame 75. The aircraft 70 is lifted beyond the tsunami estimated height. After the lifter 76 is fully lifted, the roller 70 is lowered along the raising / lowering guide rails 78 so that the net as the capturing means 80 is passed over the aircraft 70 to slightly pull it up and down. Since the holding state is attracted to the side, even if an impact load caused by a tsunami acts later, there is no risk of blinding or tilting.

  After that, the aircraft 70 can be returned safely by raising the capturing means 80, lowering the lifter 76, or moving both of them apart. 81 is an auxiliary staircase, which may be attached to the lifter 76 or may be self-propelled. By using this auxiliary staircase 81, many of the people in the airfield can evacuate. Therefore, a person who evacuates onto the lifter 76 using the auxiliary staircase 81 can be equipped with a control panel on the lifter 76 so that the control operation can be performed on the lifter 76. It can also be lifted and lowered by a portable remote controller. This auxiliary staircase 81 can be applied to other embodiments. The link type lifter 76 may be configured in place of a hydraulic or electric cylinder type lifter as shown in FIG.

  FIG. 20 shows another embodiment. In the embodiment, the lift 73 by the link 73, the drive cylinder, and the lift frame 75 is folded in the pit 72 and the aircraft 70 is driven to rise in an emergency. The lift frame 75 includes a pressurized air supply source. 84, and an air bag 85 that receives the pressurized air from the supply source 84 and expands and supports the wings of the aircraft 70 from both sides of the lifting frame 75 in a retractable manner within the frame. Stability against tsunami loads during and after ascent will be ensured. The link type lifter 76 may be configured in place of a hydraulic or electric cylinder type lifter as shown in FIG. The pressurized air supply source 84 may be an accumulator type or a reactive gas expansion type.

  FIG. 21 shows another embodiment. For example, in the embodiment shown in FIGS. 1 to 3, the lifter 7 stands by in the pit 3 in a contracted form, expands upward in an emergency and lifts the lifting frame 18 to evacuate the aircraft 2. However, the lifter 7 is a link type, and the raised link 10 leaves the lower part in the pit 3 and the pit 3 is left open. After the tsunami and so on, they solidify and cause a situation where the lifter 7 stops moving. When the lifter 7 stops moving, the aircraft 2 above it cannot be used, and rubble processing in the pit 3 is indispensable until it is used.

In the embodiment of FIG. 21, such a rubble into the pit is prevented and the lifter is lowered as soon as possible so that the aircraft can be used.
A pit 89 is formed on a base 88 that is a part of an airfield including the inside of the hangar, and a lower lifter 90 and an upper lifter 100 that are independently driven are arranged in two stages to form one lifter.
The lower lifter 90 includes two sets of left and right lower links 92 that form an X shape via a lower cross shaft 91, a pair of left and right lower guide rails 93, a lower lifting frame (with guide rails) 94, and a lower drive cylinder 95. It becomes. A protruding flange 96 is provided on the upper inner periphery of the pit 89, and an upper sealing material 97 and a lower sealing material 98 are provided on the flange 96. As shown in FIG. 21, the lower elevating frame 94 is shrunk during normal times and is waiting in the pit 89, but expands upward when the lower drive cylinder 95 is started in response to an emergency earthquake warning or a subsequent tsunami attack warning. After being raised, the lower seal material 98 is brought into close contact with the water-tight state.

  The upper lifter 100 is attached to a lower lifting frame 94 of the lower lifter 90 so as to be freely expandable and contractable. The upper lifter 100 includes two sets of left and right upper links 102 that form an X shape via an upper intersecting shaft 101. , A pair of left and right upper guide rails 93, an upper lifting frame (with guide rails) 104, and an upper drive cylinder 105. The upper elevating frame 104 is reduced in normal time as shown in FIG. 21 so that the upper elevating frame 104 is accommodated in the stepped portion of the pit 89 and is in close contact with the upper seal material 97 in a watertight state. When an emergency earthquake warning or a subsequent tsunami attack warning is received, the upper drive cylinder 105 is started to expand upward and lift the aircraft 107.

  The upper drive cylinder 105 and the lower drive cylinder 95 can be set to start simultaneously, or either the upper or lower drive cylinder 105, 95 can be started first. Preliminary capture devices 30 and 30 are installed before and after the evacuation device in the manner shown in FIGS. 8 and 9 to capture large drifting objects such as ships, containers, and houses, small drifting objects, and small debris. And it can comprise so that it may not give an impact to the principal part of a tsunami countermeasure device. Further, a secondary capturing device 108 that is a net such as a plurality of vertically oriented wire ropes or a coarse net is provided in front of and behind the upper lifter 100, or an auxiliary such as a net that is stretched between the left and right of the upper link 102. A capture device 109 can be provided. The preliminary capturing device 30, the secondary capturing device 108, and the auxiliary capturing device 109 can be configured by one or a combination thereof.

  When the tsunami hits like X, the lower lifting frame 94 of the lower lifter 90 holds the upper part of the pit 89 in a sealed state via the lower sealing material 98. On the other hand, debris and debris accompanying the tsunami flow X are first received by the pre-capture device 30, and the tsunami countermeasure device is controlled so that only the tsunami flow and mud flow will flow. On the frame 94, mud is mainly accumulated. On the other hand, since the inside of the pit 89 can be lowered by the above-described sealing, the lower lifter 90 and the upper lifter 100 can be reduced (lowered) simply by removing the deposits on the upper part. 107 can be returned to the base 88. The upper elevating frame 104 is provided with, for example, a tilting posture holding means 54 so as to stabilize the aircraft 107. Other posture holding means may be used.

23 to 26 show an example of a proposal for a tsunami evacuation device.
In the embodiment as shown in FIG. 1 to FIG. 3, the lifting frame 18 is provided in the pit 3 and the lifting frame 18 with the helicopter 2 mounted is lifted by the lifter 7 to evacuate the helicopter 2 from the tsunami when the tsunami strikes. However, if the lifter 7 is provided with the pit 3 and lifted by the lifter 7 inside the pit 3, the lifter 7 in the lifted state collides with a drifting object such as a ship or a house and causes the helicopter 2 to fall down. Furthermore, it takes a lot of time and effort to restore the tsunami flow that accompanies the mud flow into the pit 3 and collect rubble around the lifter 7 and restore them after the tsunami. There is a fear.

On the other hand, the proposed example shown in FIGS. 23 to 26 has no damage to the lifter and there is no risk of the helicopter falling, and the removal / recovery of rubble etc. can be performed quickly and relatively easily. Is.
This proposed example is also intended for an airfield, and helicopters, fighters, passenger planes, etc., or dedicated vehicles such as jeep, heavy equipment, fire trucks, etc. are set as evacuation objects 200 and they are tsunami X (push It is intended to protect against waves) and Y (pulling waves). 23 and 24 and the vertical direction in FIG. 25 are the width direction, and the horizontal direction in FIGS. 25 and 26 is the longitudinal direction.
201 shows a part of the base of the airfield including the hangar, and the upper layer part is made the surface layer part 202 made of RC like the base 201, and a square or a rectangle that forms a 20m square in the vertical direction is placed at an appropriate position downward. Openings 203 having a surface extending in a quadrangular pyramid shape are formed at one or a plurality of locations. For example, the opening 203 may be formed by laying a hollow roadbed on the foundation, instead of being made of integral RC.

  An evacuation pit 205 is formed inside the base 201 with the opening 203. The evacuation pit 205 has a rectangular planar shape having a width W of approximately 24 m and a longitudinal length L of approximately 50 m in one direction, and a depth H of approximately 15 m. The rear space that is is b, and the other front space is a. A drainage pit 206 is formed at the bottom of the space b or a of the evacuation pit 205, and the sewage that will collect in the pit 205 can be removed from the pit 205 at any time according to sensor detection by the drainage pump 207. . On the other hand, the surface layer portion 202 is formed so that the opening 203 is formed at a position corresponding to the upper portion of the space a, and the remaining portion is entirely closed. A sealing member 209 is attached to the inner periphery of the opening 203. The sealing member 209 may be provided on the side of the main lifting frame, which will be described later, or may be provided on both the member 209 and the main lifting frame side.

  A grooved steel guide rail 211 with the rail longitudinal direction oriented in the pit longitudinal direction is fixedly arranged so as to be opposed to the pit width direction at the positions of both upper side walls that are 2 to 3 meters below the pit 205. While the guide rails 211 are opposed to each other, a movable carriage 212 having a flat square shape with a certain thickness and having a certain thickness guides the advancing and retreating rollers 213 into the rails, so that the b space side and the a space side are It is said that it can freely move between. The advance / retreat is performed by driving the advance / retreat roller 213 forward / reversely by a drive device 214 which is a motor with a speed reducer.

  On the movable carriage 212 is mounted a sub-lifting frame (sub-cover) 216 having a square shape with a flat plane and a square pyramid shape with a certain thickness. The sub-lifting frame 216 is adapted to be sealed below the opening 203 through the sealing member 209 by driving up the sub-cylinder (sub-lifter) 217 and guiding the plurality of sub-guides 218. It is supposed to be. The sub elevating frame 216 is returned to the moving carriage 212 by the descending drive of the sub cylinder 217, and the sub elevating frame 216 is returned to the b space side by moving the moving carriage 212 to the b space side by the driving device 214. It is like that.

  On the other hand, 220 is a main elevating frame, which has a square plane shape and a hollow disk shape with a certain thickness like the sub elevating frame 216. During normal times, the main elevating frame 220 has a lifting lock function by a main cylinder (main lifter) 221. The main guide 222 is fitted into the opening 203 through the sealing member 209 with a stabilization function so that the evacuation target 200 is stably received from below, and foreign matter such as rainwater and mudflow does not enter through the opening 203. .

  FIG. 23 shows a normal state (standby state). The main elevating frame 220 is hermetically locked in the opening 203 by the ascending lock of the main cylinder 221, and the evacuation target 200 is on it, and a tsunami warning is always issued. It is in a state where it may be issued. The sub elevating frame 216 in FIG. 23 is in a standby state in the space b at the back of the pit 205 as shown in FIGS.

  Therefore, when a tsunami warning is issued, as shown in FIGS. 24 to 26, the main lifting frame 220 with the evacuation target 200 placed thereon is lowered by the lowering drive of the main cylinder 221 to evacuate to a low height in the pit 205. The object 200 can be evacuated.

  However, as it is, the tsunami flow and the drifting object will be drowned into the pit 205 and the evacuation target 200 will be immersed and damaged, so the driving device 214 is activated here to move the moving carriage 212 to the a space side. After the sub-lifting frame 216 is brought below the opening 203, the sub-cylinder 217 is hermetically sealed by making the sub-lifting frame 216 hermetically sealed by driving the sub-cylinder 217 upward. .

  As a result, the evacuation target 200 is not damaged at all, including tilting or falling, even if a tsunami strikes. Also, even if a large amount of rubble accumulates on the ground including the sub-lifting frame 216 after the tsunami hit, there are no obstacles such as lifters and guides extending upward, so it is early and easy to remove these rubble As a result, the debris is removed and the sub elevating frame 216 is lowered and opened, and then the movable carriage 212 is moved to return to the original space b, and the main cylinder 221 is further driven to move up to the main elevating frame. By returning 220 to the opening 203, the aircraft that is the evacuation target 200 can be quickly returned to a usable state.

  FIG. 27 shows another proposed example, in which the drive device 224 for moving the moving carriage 212 back and forth is a fluid cylinder. An electric cylinder may be used.

  FIG. 28 shows another proposed example, in which a drive device 226 for moving the movable carriage 212 back and forth is configured by a fluid cylinder or an electric cylinder 227 and an extendable drive arm 228.

FIG. 29 is a schematic plan view showing another proposed example. In this example, the driving device 230 for moving the moving carriage 212 forward and backward is connected to the moving carriage 212 side with a cylinder 231 that is a fluid or an electric cylinder. The telescopic link mechanism 232 expands and contracts between the b space side and the a space side in the horizontal plane.
In the proposed examples shown in FIGS. 23 to 29, any one of the posture holding means shown in FIGS. 1 to 7, the posture holding means shown in FIGS. 10 to 17, or the posture holding means shown in FIG. Can be applied.
