Description

  The present invention relates to an ascending evacuation facility that serves as a disaster prevention shelter that floats on the water in the event of a tsunami or flood to protect the safety of the victim.

  Conventional floating evacuation facilities include floating structures in which guide guides are deeply embedded in the foundation. However, the facilities are often large and require a large amount of land, and are expensive to construct and maintain. In many cases, it cannot be easily moved or installed. (For example, refer to Patent Document 1.)

  In addition, the capsule type was swept away at the time of rising, and at the same time, it was tossed by strong winds that could occur at the same time, making it difficult to live, and it was impossible to return to the original place when the water level was low. Investment efficiency is low because it is exclusively for evacuation. (For example, refer to Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5.)

  Therefore, the facilities that are currently required are not provided. This is because there is no time to list examples of evacuation methods for disaster prevention on TV and publications. This suggests a high potential demand for floating evacuation facilities in tsunamis and floods.

  Noto 3110611   JP 2004-305737 A   Japanese Patent No. 3541197   JP-A-10-159388   JP 09-140817 A

  Since the conventional floating building as described above has a large financial burden, it is difficult to install it in a disaster prevention designated area. In addition, the provision of a capsule type in a private house has a problem that it is treated as a buzz during normal times.

  The present invention provides a facility that can be used easily over a wide age group and that can be evacuated reliably with simple operations that are performed daily during tsunamis and floods. Another object is to reduce the economic burden by allowing some kind of use not only in an emergency but also in normal times and enable individual installation.

  The floating evacuation facility according to the present invention is provided with a link that anchors the floating portion to the base so as not to be washed away by running water when ascending.

  In order to improve the stability of the floating part and to return to the original place when the water level is reduced, the tethered link opens and closes while maintaining the attitude and orientation of the floating part.

  In order to prevent a momentary jump due to a gusty wind such as a typhoon when a normal floating part is closed and closed, the link fulcrum located above when deployed is positioned lower than the link fulcrum located below when deployed and closed.

  The levitation evacuation facility of the present invention does not require any activation operation so that even a child or an elderly person can evacuate easily. When water is pulled, it automatically returns to its original position. In addition, the floating base and the link base that supports it work reliably, and daily use is not necessary for pet breeding and garages, and it is not necessary for capsule-type equipment invented so far. It expands the range of use to difficult everyday life and realizes refuge facilities while having fun. Because this equipment can reduce the space required for installation, it is more space-saving than conventional large floating structures, can be provided at low cost, and can be installed by individuals. , Evacuation time from home can be shortened.

BEST MODE FOR CARRYING OUT THE INVENTION

A first embodiment will be described with reference to FIGS. 1 and 3 are a side view and a front view of the ascending and evacuation facility when ascending. FIG. 2 is a side view of the ascending evacuation facility shown in FIG. In the figure, GL indicates the ground, and WL indicates a water level at the time of an assumed flood.
In FIG. 1, reference numeral 1 denotes a floating part, and the inside is a space, which is used for breeding daily pets. When a tsunami or flood occurs, a human escapes and rises when the surrounding area is filled with water. Reference numeral 2 denotes a base, which is fixed to the ground.

  Reference numeral 3 denotes a link, the upper end of which is connected to the floating support 4 via a link fulcrum with the floating connection member 7, and is connected to the base 2 via a link fulcrum with the base connection member 6. Yes. Reference numeral 4 denotes a floating base, which forms the bottom of the floating part 1. Reference numeral 5 denotes an entrance door, which is located above the water line (not shown) of the floating portion 1 and is watertight.

    5 and 6 are perspective views showing only the link and the upper and lower connecting portions. A parallel link is formed by the upper beam 41 that forms the periphery of the floating base, the link arms 31 and 33, and the lower beam 21 that forms the periphery of the base. Since the posture and direction of the upper beam 41 are restrained by the link mechanism, it rises without tilting or turning during a flood, and the front and rear positions only slightly change.

  In order to obtain the rigidity of the link mechanism, the upper beam members 42 and 44, the link arms 32 and 34, and the lower beam member 22 are arranged. The reinforcement by these bars can suppress the swaying due to water flow and wind waves during the ascent.

  The levitation evacuation facility constructed as described above will be described with reference to FIG. A human enters the inside of the floating part 1 through the entrance / exit 5 and closes the entrance / exit 5. The entrance / exit 5 is water-tight and the inside of the floating part 1 is sealed. When the water is filled, the floating part 1 rises and evacuates due to flood.

  Explain tethering during ascent. First, the link 3 plays a role to prevent the floating portion 1 from flowing into the flowing water when the floating portion 1 is lifted. In addition, the rolling and pitching caused by the strong wind that can occur at the same time when the floating part 1 ascends is eased, the stability inside the floating part 1 is improved and the comfort is improved. . In the case of a tsunami, the water that flows into the land from the sea returns to the sea as a rapid tide. Because there are many disasters drawn at that time, safety can be improved by automatically returning to the original place.

  We will explain how to prevent momentary jumps caused by typhoons such as typhoons when the floating part is closed without water. As shown in FIGS. 1 and 2, the connecting members 6 and 7 that are at both ends of the link arm 3 and are connected to the base and the floating portion have a required length. Due to the length of this connecting material, the fulcrum on the floating portion side becomes lower than the fulcrum on the base side in the closed posture shown in FIGS. In this state, the wind pressure in the direction B shown in FIG. 2 acts in a direction to push the floating part downward. Further, the wind pressure in the A direction has a component force in the direction of pushing up the floating part upward, but this component force disappears when the heights of both fulcrums are equal, so there is no possibility that the wind in the A direction will float.

  FIG. 4 differs from the present embodiment in that the fulcrum at both ends of the link arm is provided directly on the upper and lower beams without using a connecting material. As is apparent from the figure, the wind pressure in the A direction works to push down the floating part, but the wind pressure in the B direction works to push up. Since the vertical component force of the own weight against the pushing force decreases with the link unfolding, once it starts to lift, there is a risk of unfolding and breaking the link.

  The levitation and evacuation facility of the present invention configured as described above evacuates due to water damage by moving upward in the B direction and generating an upward force due to buoyancy in the floating portion 1 only when water is filled. Known safety measures can be applied to safer water levels than expected. For example, a link disconnection unit is provided so that it can be operated from inside the floating room. Alternatively, the inside of the link can be expanded and contracted by a slide structure having a multiple structure, and the depth of water resistance can be further increased.

  FIG. 7 is a perspective view showing a closed state of the present embodiment. The link mechanism is stored under the floor, and the floating part has the appearance of an ark. FIG. 8 shows the internal arrangement. 11 is a pet orientation inside the floating part 1. Reference numeral 12 denotes an emergency nap place inside the floating part 1. Reference numeral 13 denotes an upper entrance in the floating part 1. 14 is a buoyancy material inside the floating part 1, and the outer wall is damaged by drifting material, and buoyancy can be obtained even if it is submerged. Reference numeral 15 denotes an emergency article storage place inside the floating part 1.

FIG. 9 is a conceptual diagram when the link is of a two-stage type. Although the structure of the link is complicated, there is an advantage that the plane position of the floating part does not move with opening and closing. This is advantageous when there is no room for installation.

    FIG. 10 is an external view when used in a daily garage. If the car door has a watertight structure and the buoyancy of the floating part is sufficient, it can be lifted and evacuated with the car. Of course, you may evacuate without entering the car.

  FIG. 11 is an external view of a form used as a fixed roof for a daily garage. The base 2 in Example 1 is supported by a pillar, and the lower part is used as a garage. It can be transferred from the veranda on the second floor of your home and evacuated. Moreover, since it is located above the garage, the depth of water resistance is increased by the height of the garage. Conversely, when the water depth is assumed in advance, the length of the link can be shortened. Currently, garages are becoming a necessity in every home, and it is an effective way to utilize space especially in densely populated areas.

  FIG. 12 is a view in which the upper floor of a known elevating type two-stage parking apparatus is a product of the present invention, and is an external view in which vehicles enter and exit the upper floor. FIG. 13 shows a state in which valuable articles and vehicles that are not frequently used are stored on the upper floor. Under the levitation evacuation facility, it will be used for parking lots for regular vehicles. FIG. 14 is an external view in which a floating evacuation facility achieves its purpose while a two-story house that is filled with water during a tsunami or flood is submerged. In order to maintain multiple vehicles in a densely populated area, a multi-story parking lot is an effective method for space utilization.
