Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that can be used for fire extinguishing as a disaster prevention device when water is stored by using waste products.

[0002]

In recent years, great disasters such as the Great Hanshin Earthquake have attracted attention, and there has been a remarkable improvement in awareness of disaster prevention in ordinary households. Since water is important as an emergency preparedness, an increasing number of households store drinking water in large used containers. PET bottles for soft drinks and alcoholic beverages (containers made of polyethylene terephthalate, with a standard capacity of 1.5 liters, but more than this) are also one of the containers used for storing water. .

The water thus stored can basically be used for extinguishing a fire in the event of an earthquake. However, at a time when the flame is small, the water in the PET bottle can fall down, but when the flame becomes large and the radiant heat becomes strong, it is difficult to approach the flame. In that case, a means for discharging water from a distant position such as a pump is required.

In view of the above points, the present invention is a reservoir for preparing for a disaster, and an object thereof is to be able to discharge water as a fire extinguishing means.

DISCLOSURE OF THE INVENTION The present invention comprises a connecting portion to which an opening of a waste container such as a PET bottle is mounted and a rubber covering a small hole connected to the container when pressurized air is introduced. A pressure accumulator that has a capillary that can be connected to the inflator of a domestic bicycle that opens to pressurize the inside of the container, and a valve that is slid by a handle that constantly seals the valve body. It is characterized by having a part and a main body.

Since a PET bottle used for commercially available soft drinks and the like is used as a container, it is possible to use a waste product and it is reasonable. The shape of the opening of this PET bottle is a standard size of 1.5 liters. If there is, there is no difference between manufacturers and it is uniform.

[0007] Further, since it can be pressurized by using an inflator of a home-use bicycle through the accumulator, it is convenient, and it does not need to be inadvertently made high in pressure and does not use CFCs or petroleum-based gas. Accumulation of pressure can be performed safely without risk of leakage or environmental damage.

Further, another invention is that a container into which water is injected, a pressure accumulating unit having a capillary connected to the container to pressurize the inside of the container when pressurized air is introduced, and a container when inserted into the container. A pipe having an air reservoir therein, and a pressurization target shown on the pipe to be compared with a water level based on a change in the volume of the air reservoir changing with the pressure in the container. .

By comparing the water level inside the pipe with the target of pressurization, it is possible to know whether or not pressurization is sufficient, which is simple, and it is not necessary to measure with a pressure gauge, and it is easy for an layperson.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. FIG. 1 shows an accumulator water storage device equipped with a PET bottle as an embodiment utilizing the present invention.

In FIG. 1, the pressure-accumulation water storage device is almost formed by resin molding, and a flow path 13 is formed from a valve seat 12 formed in a connection port 11 of the main body 1, and the flow path 13 is bent substantially vertically. A nozzle 14 is formed at the other end of the.

A flange 16 with which the PET bottle 2 is brought into contact with the outer periphery of the opening of the connection port 11 via a rubber packing 15.
The pressing portion 3 having the bag portion 31 that is in contact with the flange 16 is screwed into the opening portion 21 of the PET bottle 2 to mount and fix the PET bottle 2 having the water 22.

Inside the connection port 11, a valve seat 12 that projects in a tubular shape and is connected to the flow path 13 is formed, and a valve body 41 that seals the valve seat 12 is arranged. It is connected to the locking portion 43 through. Also, the cylindrical valve seat 1
The outer periphery of the PET bottle 2 is adhered and fixed to the inside of the pipe 44, and the pipe 44 is connected to the flow path 13 of the main body 1 in the PET bottle 2
The flow path is from the bottom of the.

A locking portion 43, which slides by being connected to the valve body 41 via a shaft 42, is a pin 45 which is constantly hooked on the main body 1.
The valve body 41 is pressed against the valve seat 12 at the same time. This pin 45 is removed at the time of use, and the locking portion 43
Can be pressed by a handle 46 provided on the upper side of the opposed main body 1.

Further, the connection port 11 of the main body 1 is provided with a pressurizing portion 5 to which an inflator of a domestic bicycle (not shown) can be connected. As shown in FIG. 2, the pressurizing unit 5 includes an injection pipe 51 and a rubber pipe 52, and a screw pipe 53, a lock nut 54, a cured rubber 55 and an injection pipe retainer 56 are provided to fix them. There is.

The injection pipe 51 is in the form of a test tube whose one end is sealed, and the rubber pipe 52 is covered from the tapered portion to be sealed. In the tapered portion of this injection pipe 51,
Several small holes 57 are provided and are normally enclosed by a rubber tube 52. Then, when pressurized air is inserted, for example, by inserting the tip of an inflator of a bicycle (not shown) into the injection pipe 51, the pressure causes the rubber pipe 5 to pass through the small hole 57.
2 swells and the pressurized air in the injection tube 51 enters the main body 1 (as indicated by the arrow in FIG. 2). Also,
When the inside of the main body 1 is pressurized, the rubber tube 52 is pressed against the small hole 57 by the internal pressure and is sealed.

The injection pipe 51 is fixed by fixing a screw pipe 53 screwed to the main body 1 with a lock nut 54, and
3, the injection pipe retainer 56 is screwed into the screw pipe 53, and the tapered inclined portion of the injection pipe 51 is pressed against the opening portion at the tip of the screw pipe 53 via the rubber pipe 52. Let A hardened rubber 55 is disposed inside the main body 1 of the screw tube 53 to seal the space between the main body 1 and the screw tube 53 with internal pressure.

Further, the connection port 11 of the main body 1 is provided with a safety valve 7. As shown in FIG. 4, the safety valve 7 is made up of a ball 71 and a spring 72, and a tubular body 74 is adhesively fixed to fix them in the hole 17 of the main body 1 via a packing 73. A protective net 76 is provided in the hole 75 of the cylindrical body 74.

The ball 71 is constantly pressed by the spring 72 so as to close the hole 17 of the main body 1, and when the pressure in the main body 1 rises abnormally due to an unexpected temperature change or the like,
The ball 71 is pressed by the internal pressure to make a gap, and the main body 1
The pressure inside is released to the outside. Therefore, even if the pressure in the PET bottle 2 is abnormally increased during pressurization or storage, the pressure can be released through the safety valve 7 and unexpected accidental explosion can be prevented.

If the setting of the safety valve 7 is set within a safe pressure range and the pressure until the pressure is released from the safety valve 7 is set as the pressurization target, it is not necessary to display the degree of pressurization by the pipe 44 described later.

A method for preparing the above-mentioned accumulator water storage device will be described below.

First, a predetermined amount of water 22 such as tap water is injected into a PET bottle 2 which may be a waste product after drinking commercially available soft drink, etc., and the PET bottle 2 is connected to the connection port 11 of the main body 1. The main body 1 and the PET bottle 2 are fixed to each other by screwing the pressing portion 3 into the opening 21 of the PET bottle 2.

At this time, the PET bottle 2 has the opening 21
May have a specified shape and a specified capacity, but it is preferable to use a PET bottle for carbonated drinks. In addition, commercially available natural water may be used as it is by adjusting the water level.

Next, an inflator (which may be for business use) of a domestic bicycle is prepared, and the tip of the inflator (not shown) is inserted into the injection pipe 51 of the pressurizing section 5 of the main body 1 and compressed air is put into the PET bottle 2. Send in 6. At this time, as an index indicating the degree of pressurization, the compressed air 6 is fed within a safe range by adjusting the water level of the air pool 61 in the pipe 44 visible in the transparent PET bottle 2 to a predetermined position. You can

Then, the PET bottle-based accumulator water storage device is stored as emergency drinking water and a simple fire extinguisher together with an emergency tool for disaster. At this time, it is preferable to prepare a plurality of pieces, but it is sufficient to match the space.

In the unlikely event that the flame rises due to the mistreatment of cigarettes, the PET bottle-based accumulator water storage device is taken out from the storage location, and the pin 45 is first removed. Then, the handle 46 is grasped with the nozzle 14 of the main body 1 directed toward the fire source. Then, the valve body 41 that slides together with the locking portion 43 via the shaft 42 separates from the valve seat 12, and the water 22 in the PET bottle 2 is pushed out by the compressed air 6 through the pipe 44 and the flow path 13 of the main body 1. Be done.

Here, when this PET bottle-based accumulator water storage device is used only for a simple fire extinguisher, the water 22 may be a solution of a strengthening liquid or a wetting agent, and in the case of a strengthening liquid, it is also used for a tempura fire. When the wetting agent is used, it can penetrate and extinguish deep fires such as bound newspapers and duvets. However, since the filling amount is limited in any case, it is optimal to prepare a plurality of each by distinguishing only water from the one containing the drug when preparing a plurality.

Furthermore, even after using this PET bottle-based pressure storage water storage device, it can be used many times by injecting water 22 again and pressurizing it.

A method of confirming the degree of pressurization by the water level during pressurization in the PET bottle 2 will be described with reference to the PET bottle 2 and the pipe 44 shown in FIG. In the pipe 44, an initial zone SB, a pressure zone PB, and a danger zone DB are shown as transparent colored portions to be compared with the water level of the air pool 61.

First, a predetermined amount (for example, 1 liter) of water 22 is poured into the PET bottle 2 (for example, 1.5 liter). Then, the pipe 44 is inserted at the time of fixing to the main body 1 and the water level changes slightly. At this time, it is confirmed whether the water levels of the initial zone PB and the water 22 on the outer periphery are within the range of the initial zone PB. This initial water level is the water level shown by the dotted line in FIG. 3, and the water level in the pipe 44 is located at the lower end of the pipe 44. Here, let's check a simple caution about the water level.The water level is curved near the wall surface due to the surface tension of the water, but the lower end part where the water surface normally forms a horizontal surface is the water level (common water level If you do not take a look at, it is necessary to note the explanation of the water level).

When pressure is applied from the pressurizing section 5, the compressed air 6 pressurizes the water 22 (see the arrow in FIG. 3) and the air pool 61 in the pipe 44 is similarly pressurized (see FIG. 3). (See arrow), the water level in the pipe 44 rises. And
When the water level in the pipe 44 becomes the pressure band PB, PET
Since it can be seen that the inside of the bottle 2 has been pressurized to a substantially predetermined pressure (for example, 2.5 kg), the pressurization is terminated. Where P
Even if there is a difference in the capacity of the ET bottle 2 depending on the manufacturer, if the capacity of the pipe 44 is constant, the relationship between the volume of gas and the pressure will appear in the volume of the air reservoir 61 as it is (2.5 (In the case of kilo, it is compressed to 2/5), and when it is halved, the pressure doubles. Further, since the volume of gas is naturally influenced by temperature, the pressure band PB is set to a safe range in consideration of the influence of ambient temperature.

In such a PET bottle-based accumulator water storage device, the pressure in the PET bottle 2 is slightly released during normal storage, but it is considered that the pressure rises due to seasonal changes and storage locations. To be In such a case, P
Since the pressure increase in the ET bottle 2 appears in the water level of the air reservoir 61 as described above, it is located above the pressure band PB.
Then, in a range where the PET bottle 2 does not explode (for example, 3.5 km), a dangerous zone DB indicating a danger is shown, and when the water level reaches or exceeds the dangerous zone DB, it is dangerous to have a high pressure. Can be recognized. In the case of this embodiment, a safety valve 7 is provided and the spring 7
By choosing a strength of 2, it can be no higher than that pressure. By showing the pressurizing band PB, it is preferable to loosen the pressing portion 3 to release the pressure from the compressed air 6 even when the safety valve 7 is absent or disabled when a dangerous state occurs. Actually the main body 1
It is preferable to reattach and re-pressurize.

Although the above water level comparison is shown as the transparent colored portion shown on the pipe 44, each may be shown as a target line. In this way, by comparing the water level inside the pipe with the target of pressurization, it is possible to know whether or not pressurization is sufficient, which is simple, and there is no need to measure with a pressure gauge, and it is also easy for an amateur.

In the above embodiment, the PET bottle 2
Can specify one target display of pressurization of the pipe 44 by specifying the volume, but there are multiple types of PET bottles 2 of commercially available soft drinks, and the distance to the bottom is also different, The pipe 44 may be made flexible so as to provide a pressure target according to various sizes. Also, the pipe 44
May be prepared for various PET bottles.

As described above, the connection part by the connection port 11 in which the opening 21 of the PET bottle 2 is mounted as a waste container and the small hole 57 connected to the PET bottle 2 when the pressurized air is introduced are covered. A rubber accumulator formed by a pressurizing unit 5 having an injecting pipe 51 as a capillary to which an inflator of a domestic bicycle for opening and pressurizing rubber of a rubber pipe 52 can be connected, and a valve body 41 slid by a handle 46. Since the main body 1 has a water discharge part having a nozzle 14 at the tip of the flow path 13 that is constantly sealed, and the PET bottle 2 used for commercially available soft drinks etc. is used as a container, waste products can be used. It is reasonably priced, and the shape of the opening 21 of the PET bottle 2 is uniform.

Further, since it can be pressurized by using an inflator of a domestic bicycle through the pressure accumulator, it is convenient, and it does not need to be inadvertently made high in pressure and does not use freon gas or petroleum-based gas. Accumulation of pressure can be performed safely without risk of leakage or environmental damage.

Further, another invention is a PET bottle 2 as a container into which water is injected, a pressure accumulating section for pressurizing the inside of the PET bottle 2 when pressurized air is introduced, and a PET bottle. Pressurization shown in the pipe 44 which has an air pocket 61 inside when inserted in 2 and the water level based on the change in volume of the air pocket 61 which changes with the pressure in the PET bottle 2. Since it has a target of pressurization by the band PB, by comparing the water level inside the pipe 44 with the pressurization band PB, it is easy to know whether or not the pressurization is sufficient, which is simple and does not require measurement with a pressure gauge. , Easy for an amateur.
