TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a multi-purpose multi-function water tank having a basic function as a water tank for storing domestic water, fire protection or fire-extinguishing water, and particularly having a function that can be used as an emergency boat.
[0002]
[Prior art]
Conventionally, a disaster countermeasure facility shown in FIG. 8 has been known. This disaster countermeasure facility includes a heat-resistant metal main body 1 having a hollow portion 1a for cooling water storage in the periphery thereof, and an airtight and watertight water-tight door 2 which can be opened and closed from outside and indoors on one side of the heat-resistant metal main body 1. A ventilation opening 11 is provided at the upper part of the heat-resistant metal body 1 for ventilation inside and outside so that it can be opened and closed from inside the room. Cooling water to the hollow portion 1 a of the heat-resistant metal body 1 is supplied to the heat-resistant metal body 1. It is configured such that it can be supplied from a water tank 20 provided inside (for example, see Patent Document 1).
[0003]
According to this kind of disaster countermeasure facility, the door 2 can be opened and closed by operating the handle 7 for closing outside, so that objects can be taken in and out, and people can go in and out. That is, when using as a storage, articles are appropriately loaded and arranged with the ventilation opening 11 opened. When used as an evacuation room for people, the door 2 is closed by operating the inner closing handle 8 after entering the room, and lighting means such as an electric light 25 is turned on.
[0004]
On the other hand, when an external harmful gas enters through the ventilation port 11 due to a fire or the like, the ventilation port 11 is closed, the oxygen cylinder 18 is opened, and oxygen is supplied to the facility to compensate for the oxygen deficiency. By setting the pressure in the facility to be higher than the outside by about 0.01 to 0.2 atm, it is possible to prevent harmful gas from entering from outside during air replacement (air discharge). .
[0005]
On the other hand, when there is no harmful gas in the outside air, the ventilation port 11 is opened without using the oxygen cylinder 18, the room is kept at atmospheric pressure, and water enters from the ventilation port 11 due to a tsunami or the like. If the ventilation port 11 is blocked by an avalanche, a landslide, or the like, the ventilation port 11 is closed and the oxygen cylinder 18 is used as described above.
[0006]
Further, in the heat-resistant metal main body 1, water in the water tank 20 can be taken out from the faucet 22 and used for drinking or the like. The water in the water tank 20 enters the hollow portion 1a of the main body 1 through the water passage pipe 23, and also enters the hollow portion of the door 2 through the flexible tube 3 (having the same water level as the water tank 20). In the event of a fire or the like, the interior of the room is prevented from being heated due to the action of the heat insulating material 5.
[0007]
When the outside temperature rises due to a fire or the like, evaporation of water in the hollow portion 1a is promoted, and water vapor is stored in the upper portion of the hollow portion 1a. The water vapor exits the main body 1 through the water vapor outlet 15. At this time, if there is the steam cooling umbrella 14, it is cooled by hitting the umbrella 14, drops as water droplets, and acts to cool the outside of the main body 1.
[0008]
When the oxygen pressure in the heat-resistant metal main body 1 rises excessively, the indoor pressure valve 12 is automatically opened by the oxygen pressure, and the gas pressure is controlled by releasing excess oxygen. When the drinking water in the facility runs out, the preliminary outlet 28 is used.
[0009]
In addition, in order to prepare for a fire or the like, the indoor temperature rise is suppressed by various means. That is, in the outermost ventilation space 1b, the temperature rise is prevented by convection of the air, and water cooling is performed in the hollow portion 1a inside the space, and the water vapor evaporated there hits the water vapor cooling umbrella 14 of the water vapor outlet 15. The outer surface of the main body 1 is cooled by dropping as water droplets. Further, a heat insulating material 5 is provided inside the hollow portion 1a.

In these figures, a multipurpose multifunctional water tank 30 is removably mounted on a roof 32 of a structure 31. The structure 31 is desirably formed of, for example, a container as illustrated. Of course, a roof such as a general building or a veranda may be used as the structure 31. However, when a general building is used as the structure 31, it may be necessary to secure the strength so that the water tank 30 can be detachably mounted by appropriately reinforcing the building.
[0026]
The multi-purpose multi-function aquarium 30 is made of fiber reinforced plastic (FRP), and has a substantially rectangular planar shape depending on the planar shape of the roof 32, and the bottom surface thereof is placed on the roof 32. It is mounted detachably. Of course, it is recommended to fix the roof 32 appropriately in order to prevent misalignment due to vibration or strong wind.
[0027]
As shown in FIGS. 5, 6, and 7, the versatile multifunctional water tank 30 includes a first water reservoir 51 having a bottom and an open upper surface, and a second water reservoir 52 having a closed cross-sectional structure. The second water storage section 52 has a composite structure surrounding the first water storage section 51, and is partitioned into a lower water injection chamber 52A and an upper buoyancy generation chamber 52B in which only air exists. ing. Further, the inside of the water injection chamber 52A is partitioned by a plurality of partition walls 33 so as to allow water to flow therethrough so as to suppress swinging of water in the water injection chamber 52A.
[0028]
On the other hand, a first drainage system 34 is provided in the first water storage unit 51, and a second drainage system 35 is provided in the water injection chamber 52 </ b> A of the second water storage unit 52. The first drainage system 34 includes a drainage pipe 36 for communicating the first water storage part 51 with the outside, and a drainage valve 37 interposed in the drainage pipe 36. The second drainage systems 35, 35 are connected to the water injection chamber 52A. A drain pipe 38 communicating with the outside and a drain valve 39 interposed in the drain pipe 38 are provided. The water supply chamber 52A is provided with a water supply system 42 having a water supply pipe 40 and a water supply valve 41 interposed in the water supply pipe 40.
[0029]
In the configuration described above, the multi-purpose multi-function water tank 30 normally closes the drain valve 37 of the first drain system 34 and the drain valve 39 of the second drain system 35 and opens the water supply valve 41 of the water supply system 42. Then, rainwater or tap water is stored in the first water storage section 51, and tap water is injected into the water injection chamber 52 </ b> A of the second water storage section 52 to be stored outdoors. That is, it is installed outdoors in a state where it is detachably mounted on the roof 32 of the structure (for example, a container) 31.
[0030]
Rain water or tap water stored in the first water storage unit 51 is discharged from the first drainage system 34 by potential energy obtained by, for example, detachably mounting the multi-purpose multi-function water tank 30 on the roof 32 of the container 31. The tap water which is taken in through the drainage pipe 36 and stored in the water injection chamber 52A of the second water storage section 52 is taken out through the drainage pipe 38 of the second drainage system 35 to be used as living water according to the purpose. Can be used for selection. That is, rainwater or tap water stored in the first water storage unit 51 is used for showers, toilets, and the like, and tap water stored in the water injection chamber 52A of the second water storage unit 52 is used as drinking water or water for cooking. And so on. Further, the multipurpose water tank 30 removably mounted on the roof 32 forms an external heat insulating layer on the upper surface of the roof 32, thereby preventing the roof 32 from being exposed to direct sunlight. For this reason, even in the summer, the temperature inside the container 31 can be prevented from rising excessively, and a comfortable living space can be secured, and even if a cooling system is separately provided for adjusting the room temperature. However, energy saving can be achieved and cooling costs can be reduced.

That is, drainage of, for example, rainwater stored in the first water storage unit 51 is drained by the first drainage system 34 so as to reduce the ratio of the volume of the water storage to the entire volume of the multi-purpose multi-function water tank 30. A large buoyancy can be generated by reducing the ratio of the volume of the stored water originally by the buoyancy generation chamber 52B of 51. Thereby, in a state where drinking water is stored in the water injection chamber 52A of the second water storage section 52, that is, in a state where the water injection chamber 52A is full, the multipurpose multifunctional water tank 30 is detached from the roof 32 of the container 31 and floated on the water surface. Buoyancy that does not sink even when 4 to 5 people enter the first water storage section 51 can be obtained. Therefore, the multi-purpose multi-function aquarium 30 can be used as an emergency boat when a flood such as a tsunami occurs. Naturally, it is possible to drink the water stored in the water injection chamber 52 </ b> A in the second water storage section 52 in a state of use as an emergency boat in which 4 to 5 people have boarded the first water storage section 51.
