Description

  In the present invention, regardless of whether it is a detached house or a high-rise apartment building, if each house is equipped with a facility that can always store about 100 liters of water per household, a water truck that is dispatched in the event of a disaster (an average of 2,000 liters per vehicle) ) Has been drastically reduced, and elderly people, people with disabilities, and those with weak physical strength who are being treated for illness do not need to line up for a long time with a plastic container in a water truck that is dispatched at the time of water outage. For various people other than normal and healthy people, the water pressure has decreased as usual, but it can be used from an indoor faucet (such as a sink), ensuring tap water, etc. This reduces the burden on both the victims and the rescuers.

  Conventionally, there are some facilities where a water tank is installed outside or indoor in a detached house, and this is pressurized with water, or an elevated water tank is installed, and water is supplied by gravity, but the construction and running costs were considered. Sometimes it is not possible for the general public, and most detached residents use water pipes drawn directly from water pipes laid on the roads of local governments.

  On the other hand, in collective housing (including high-rise buildings), the amount of water stored varies depending on the building (number of households), but a water tank that can secure the amount of water equivalent to about one day is installed, and this is pumped (during power failure) Is not used) and is supplied to each house under pressure.

  In recent years, the method of water supply in high-rise apartments in urban areas is to supply water directly without connecting a water supply pipe to a water supply main, installing a pressurizing device, and installing a water storage tank. It is changing to a method.

  Even if a water tank is installed, if a water outage continues even after 1 to 2 days at the time of a disaster, it becomes impossible to secure water, and a situation of immediate water outage occurs in a detached house.

At present, there is no small water tank in each house (household) that uses tap water that is safe from natural taps (gravity type) for emergency disasters.

  Since the present invention uses a natural drop (gravity type), it is necessary to install a water storage tank at a position higher than the faucet normally used.

  The present invention requires a container that can cope with the water supply pressure during normal times (when not in a water shut-off state).

  The present invention requires safety measures for water leakage (water leakage, etc.) in the water storage tank and peripheral devices.

The present invention requires dew prevention and heat retention measures including treatment of water droplets due to condensation (a phenomenon due to temperature difference).

  In the present invention, it is necessary to automatically allow air to enter the small water tank when it is in a water-stopped state, and when water supply is started after completion of the restoration work, the water is vented (exhausted) to the water supply. Water needs to flow smoothly.

The present invention requires measures to prevent back flow from the small water storage tank to the water supply pipe (supply side) when the water supply pipe is in a water cutoff state.

In the present invention, when the pipe from the small water tank to the faucet is damaged due to a disaster or the like, it is necessary to take measures to take out the tap water from the small water tank from a place other than the faucet.

The water supply from the water storage tank uses a natural drop (gravity type), so the water storage tank is installed at a position higher than the faucet normally used (the upper part of the system kitchen, the upper part of the washing machine, etc.).

  Containers that can handle the water supply pressure in normal conditions (when water is not shut off) are made of metal (stainless steel, etc.) capable of corrosion resistance, antifouling, acid resistance, etc. A container that withstands this pressure is used at a pressure that exceeds the working supply pressure.

  To prevent water leaks in water storage tanks and peripheral equipment, a metal (stainless steel, etc.) container is enclosed with a plastic container, and if even a small amount of tap water leaked from the container is stored in the plastic container, the leak is detected. A shut-off valve is attached to the route coming from the water supply to shut off the water supply and issue an abnormal lamp display, buzzer alarm and alarm output.

  Concerning dew prevention and heat retention measures, including water droplet treatment due to condensation (a phenomenon due to temperature difference), metal (stainless steel, etc.) containers are made of metal and plastic because dew condensation is assumed due to differences in water supply temperature and room temperature. A gap is provided between the containers, and a heat insulating material is put into the gap to prevent dew and heat.

  When water is shut down and used, air is automatically put into a small water tank so that tap water with a low water pressure flows smoothly, and when water supply is started after completion of restoration work, An air vent valve is installed so that water can be discharged smoothly.

Regarding measures to prevent back flow from the small water tank to the water pipe when the water pipe is shut off, the water pressure disappears when the water pipe flowing into the small water tank is shut off, and the pressure of the small water tank is higher Therefore, a countermeasure is taken to prevent backflow by installing a check valve against the backflow to the water supply side.

In addition, a shut-off valve is installed between the water supply side and the water storage tank, and measures are taken so that the shut-off valve is automatically shut off and does not flow backward when the pressure inside the storage tank is detected and the pressure drops.

If the pipe from the small water tank to the faucet is damaged due to a disaster, etc., a manual valve is installed in the pipe to the faucet to prevent the tap water from the small water tank from being taken out of the faucet. Is to be installed.

  Conventionally, in the event of a disaster such as an earthquake or storm and flood, when a water outage situation that prevents water supply occurs due to damage to the water supply pipe, which is one of the lifelines, an indoor small water tank is installed to secure emergency drinking water for home use. By simply storing the tap water, when there is a temporary water outage (no water supply), each house has one household, about 12 liters a day (4 people X3L / day), a minimum of 5-7 days The amount can be secured and tap water can be supplied even in the event of a water outage or power outage.

  Even if normal tap water is stored for about a week (about 7 days), there is no problem, and since water is normally supplied via a small water tank, it is not necessary to change the water in the water tank. It is.

  To describe the present invention, a metal container is put in a plastic container, and tap water is supplied from a water supply pipe to a double container in which a heat insulating material is put in a gap between the metal container and the plastic container. The tap water stored in the water tank is taken out from one side and connected to a normal faucet, and the tap water is supplied to the faucet via the water tank at normal times.

  In the event of a water outage in the event of an earthquake or storm and flood disaster, the check valve installed at the place where the water supply pipe is connected to the water tank works, the tap water is stored in the water tank, and the water tank is connected to the faucet. Therefore, tap water comes out from a normal faucet.

When the pipe from the small water tank to the faucet is damaged due to a disaster, tap water stored in the water tank can be taken out from a manual outlet other than the faucet.

  It detects water leakage in the water tank and the remaining water amount of the water tank, and issues an abnormal lamp display, buzzer alarm and alarm output even if there is no commercial electricity from the monitoring panel.

  The present invention is a water storage tank having a structure in which a metal container 2 is placed in a plastic container 1 and a heat insulating material 3 is placed in the gap.

A water tank inlet 4 for supplying tap water from the water pipe to the water tank, a check valve 10 and a shut-off valve 11 installed in front of the water tank, and a water tank outlet connected to the normal water tap from the water tank ( A pipe for supplying water) 5 is installed.

An air vent valve 12 for automatically venting the water in the water tank is installed at the upper part of the water tank.

A manual valve 13, a manual valve 14, and a manual outlet 15 are installed in the pipe to the faucet so that tap water in the small water tank can be taken out from places other than the faucet.

A water leakage detection sensor 6, a water tank remaining amount detection sensor (water tank lower level) 7, a water tank remaining amount detection sensor (water tank upper level) 8, and a water tank pressure switch 9 are installed in the water tank. This is input to the monitoring panel 16, and the control of the shutoff valve 11, the abnormal lamp display, the buzzer alarm and the alarm output 17 are issued.

  In the present invention, regardless of whether it is a detached house or a high-rise apartment building, if each house is equipped with a facility that can always store about 100 liters of water per household, a water truck that is dispatched in the event of a disaster (an average of 2,000 liters per vehicle) ) Has been drastically reduced, and elderly people, people with disabilities, and those with weak physical illness need not be lined up for a long time by holding a plastic container in a water truck that is dispatched at the time of water outage. For various people other than those who are healthy or healthy, the water pressure is reduced as usual, but it can be used from an indoor faucet (such as a sink), ensuring tap water, etc. This will reduce the burden on both the victim and the rescuer.

It is the top view which showed the indoor ceiling suspension type gravity-type small domestic water tank for emergency disaster response.
