Description

The present invention relates to a liquid storage device and a liquid storage method.

In recent years, it is fresh in my memory that unexpected large-scale disasters such as the Great East Japan Earthquake and the heavy rain disaster in Mabi Town, Hiroshima Prefecture have occurred. For this reason, various disaster prevention goods called disaster prevention goods have been devised and sold. For example, even the equipment necessary for stockpiling drinking water, which is essential for life support, is prepared for unpredictable natural disasters. It cannot be said that it has spread widely to the home.
For this reason, in the event of a water outage due to a disaster, the victims who hold a conventional heavy polyethylene resin tank in their hands and line up in a long line on the water truck will not disappear. is there.
Generally, in the event of an emergency such as a natural disaster, the amount of drinking water required by a person is at least 3 liters per person per day, and this required amount should be stockpiled for a total of 9 liters for 3 days. Is recommended. Therefore, in the case of a family of four, it is necessary to stockpile 36 liters of drinking water. In relation to this method of transporting drinking water, various proposals have been made to reduce the load during transportation.

For example, Patent Document 1 describes a water tank in which a transport container and a small rotary wheel are combined. Further, Patent Document 2 describes a method of carrying a water supply tank in which a transport container and a small rotary wheel are combined on the back and carrying the transport container itself to a higher floor using a belt. Further, Patent Documents 3 and 4 describe a device for reducing the load at the time of towing by adding a rolling wheel to the tank. Furthermore, overseas, mainly in Africa and Southeast Asia, where the water supply infrastructure is underdeveloped, the polyethylene tank itself is molded into a barrel shape, and the tank is passed through a handle or rope through the bearings and through holes provided in the center of both ends of the barrel. There is a tank designed to rotate itself.

However, with the related technology described above, there is a concern that small rotating wheels will be buried in the rubble and it will be difficult to drive at a disaster site where rubble is scattered due to an earthquake or heavy rain. Problem is expected. On the other hand, the barrel-shaped polyethylene tank devised overseas is intended for use on flat terrain with few obstacles such as grasslands, so when used in disaster areas, the side surface of the barrel-shaped polyethylene tank is directly on the ground. There is a concern that the side surface may be damaged by rubble or the like. In addition, because of the barrel shape, the polyethylene tank itself will tip over if there is no width to some extent, and the volume of the polyethylene tank itself will increase. In addition, if the rolling wheels and tank are integrated, even if it is difficult to transport, in a multi-story apartment building, if the elevator cannot be used due to a power outage, use the stairs. The only way to carry it to the upper floors is to lift a large polyethylene tank, which has the problem of causing great physical and mental fatigue of the carrier.

An object of the present invention is to provide a liquid storage device that is easy to carry.

In order to solve the above problems, the present invention proposes the following means.
The liquid storage device according to the first aspect of the present invention includes a plurality of rotary support members arranged in the axial direction at intervals in the axial direction, having a shape of a rotating body or a polygonal shape similar thereto. It is arranged between these rotation support members, is detachably connected to the rotation support member, and has a storage portion having a liquid storage space inside.

The liquid storage method according to the second aspect of the present invention includes a step of connecting a hollow storage portion between a plurality of rotary support members forming a rotating body, and a step of supplying liquid to the storage portion.

According to the present invention, the liquid can be stored in a mode that is easy to transport.

(Embodiment)
The liquid storage (transportation) device according to the embodiment of the present invention will be described with reference to FIGS. 3 to 7.
FIG. 3 shows the overall configuration of the liquid carrier, and FIG. 4 is an external view showing the entire tank, the upper surface of the tank, and the bottom surface of the tank. In the configuration of one embodiment, four tanks are used, but since they all have the same structure, one representative tank will be described.
FIG. 3 is an external view showing an example of mounting one tank for simplification of description.
With reference to FIG. 3, the basic configuration of the entire apparatus will be described together with an outline of the assembly procedure.
Reference numeral 1 is a tank for containing drinking water. A supply port for replenishing drinking water in the center of the tank 1 (indicated by reference numeral 14 in FIG. 4A) and a supply port for providing drinking water in the bottom surface (indicated by reference numeral 13c in FIGS. 4A and 4C). Is provided. A screw cap (a plug having a female screw screwed into a male screw formed on the tank 1 side) and a screw cap with a nozzle (formed on the tank 1 side) are widely distributed in the supply port 14 and the supply port 13c, respectively. A tube with a valve having a male thread that is screwed into a female thread) is used. Further, both ends of the tank 1 and the body are provided with an uneven structure during tank molding for the purpose of maintaining strength.

Ribs 2A (2B) protruding outward in the radial direction and male screw-shaped thread grooves 3A (3B) are provided on the outer peripheral portions of both ends of the tank 1 during tank molding. Here, in the case of tank molding, when molding a tank by injection molding or the like using a mold, a cavity corresponding to a rib 2A (2B) and a thread groove 3A (3B) is formed in the mold to correspond to the case. It means molding into a shape.
Side rings 4A (4B) as rotation support members are arranged on the left and right sides of the tank 1, and a center hole 5 for passing a rope or the like during transportation is provided in the center of each side ring 4A (4B). There are four insertion ports 6a to 6d for passing the tank 1 in the cross direction (at positions outward in the radial direction and at intervals of 90 degrees in the circumferential direction) from the center hole 5. .. Insert rubbers 7a to 7d having a C-shaped cross section, which are deformed by a gap with the tank 1, are mounted on the outer periphery of each of the insertion ports 6a to 6d. The insertion ports 6a to 6d are formed to have an inner diameter smaller than the outer diameter of the rib 2A (2B).

The fastener 8A (8B) screwed into the thread groove 3A (3B) of the tank 1 has the same shape as the hexagon nut, and the side ring 4A (4B) is sandwiched between the rib 2A (2B). It has a role of fixing the tank 1 to the side wheels 4A and 4B. The inner circumference of the fastener 8A (8B) is engraved with an inward female thread groove so that the fastener 8A (8B) can be tightened by being screwed into the male screw 3A (3B) when rotated.
That is, when one tank 1 is inserted into one insertion port 6a from the inside of the side ring 4A (4B), the ribs 2A (2B) provided on the outer periphery of the tank 1 and the ribs 2A (2B) and the screw groove 3A ( Since a space corresponding to the thickness of the side ring 4A (4B) is provided in advance between the 3B), the screw groove 3A of the tank 1 protrudes to the outside of the side ring 4A.
In this way, the fastener 8A (8B) is attached to the thread groove 3A (3B) protruding outward from the side ring 4A (4B), and when the fastener 8A (8B) is tightened, the tank 1 has the rib 2A (2B) and the fastener 8A ( It is fixed with the side ring 4A (4B) sandwiched between it and 8B).
Similarly, another tank 1 is attached to the remaining insertion ports 6b to 6d. By such a step, the attachment of the tank 1 to the side ring 4A on one side is completed.

Next, in order to attach the tank 1 to the side wheel 4B on the other side, the tank 1 is attached in the same manner.
The screw grooves 3A (3B) at both ends of the tank 1 are outward-facing screw grooves, and in this embodiment, the directions of the screws are opposite to each other, so that the fasteners 8A and 8B are tightened from both the left and right directions. By raising it, a loosening prevention effect can be obtained.
By the above assembly work, a wheel-shaped rotating body in which four tanks 1 are mounted between the two side wheels 4A and 4B is completed.

The configuration of the tank 1 will be described in detail with reference to FIG.
The upper surface 12 and the bottom surface 13 of the tank 1 are provided with protrusions 12a, 12b, 13a, 13b that project convexly from the surface of the tank 1 during tank molding for the purpose of maintaining strength. Further, around the cylinder-shaped body of the tank 1, uneven structures of uneven portions 11a, 11b, and 11c are provided for the same purpose.
A replenishment port 14 opened and closed by a screw cap with rubber packing is attached to an opening provided in the center of the body of the tank 1. Further, a handle 12c is attached to the upper surface 12 of the tank 1 so that the tank itself can be easily transported. A supply port 13c with a nozzle cock with rubber packing is attached to an opening provided on the outer periphery of the bottom surface 13.
Ribs 2A and 2B are provided on the outer peripheral portion of the tank 1 on the inner side in the direction of the axis C (inside 12 cm in one embodiment) from both ends of the tank 1 in order to fix and bring the tank 1 and the side rings 4A (4B) into close contact with each other. Male thread-shaped thread grooves 3A and 3B facing each other are formed during tank molding.

The screw grooves 3A and 3B are screw grooves 3A that are clockwise outward and 3B are counterclockwise outward so that they can be tightened from both the left and right directions during assembly.
Further, at the time of assembly, a mark is attached to the upper surface of the tank and a mark 13d is attached to the bottom surface of the tank in advance at the time of forming the tank so that the combination with the fastener described later can be easily understood.
Ribs 2A, 2B and threaded grooves 3A, 3B so that the threaded grooves 3A and 3B are not hidden by the side rings 4A (4B) when the side rings 4A (4B) are attached between the ribs 2A and 2B and the threaded grooves 3A and 3B. Spaces 15a and 15b corresponding to the thicknesses of the side rings 4A and 4B are provided between them in the axis C direction.

FIG. 5 is an external view showing the side ring 4A on one side. In the configuration of one embodiment, two side wheels 4A and 4B are used, but since they all have the same structure, one side ring 4A will be described.
At the center of the side ring 4A, a center hole 5 through which a rope or the like used at the time of towing passes is formed. The inner circumference of the center hole 5 is chamfered to prevent the rope and the like from being worn and cut by frictional force during towing.
Insertions 6a, 6b, 6c, and 6d are opened at 90 degree intervals in the circumferential direction at positions outside the center hole 5 in the radial direction in order to attach the tank 1. An annular insert rubber 7a, 7b, 7c, 7d having a C-shaped cross section is attached to the outer circumference of each insertion port in order to prevent the fastener from loosening. Further, since it is necessary to attach the supply port 13c on the bottom surface 13 of the tank 1 so that it faces the outer peripheral direction of the side ring 4A when the tank 1 is inserted, the triangular marks 9a, 9b, 9c, and 9d are the side rings. It is preformed at the time of molding into 4A (4B).

6 (a), (b), (c) and (d) are external views showing the fasteners 8A (8B).
The appearance of the fastener 8A (8B) is similar to that of a commercially available hexagon nut, and is manufactured by, for example, molding the same plastic as tank 1. A chamfered portion 8a is formed on the upper surface of the fastener 8A (8B) so as not to cause injury during handling such as assembly.
Four fasteners 8A with clockwise inward threaded grooves on the inner circumference and counterclockwise inward threaded grooves on the inner circumference so that the fasteners 8A (8B) can be rotated and tightened from both directions. There are four fasteners 8B, and in one embodiment, a total of eight are used.
The fastener 8A having a counterclockwise inward groove is provided with a mark 8b at the time of molding so that the direction of rotation can be easily distinguished at the time of assembly.
Similarly, the fastener 8B with a clockwise inward groove is marked with a mark 8c.

Since one embodiment is characterized in that the tank itself is used as an axle, the details of the process of assembling the tank 1 as an axle will be described.
FIG. 7 is a view when the tank 1 is fitted to the side wheels 4A (and 4B), and the fasteners 8A and 8B are attached and tightened. Arrows A and B in the figure indicate the direction of rotation of the fastener. In one embodiment, four tanks 1 are mounted, but in the description of the operation, mounting of one tank 1 will be described as an example for clarification.
First, the handle 12c side of the tank 1 is set up for temporary assembly. Next, pick up one side ring 4A (upper side in FIG. 7), finely adjust the position of the tank 1 so that it fits into one of the insertion ports 6a to 6d, and fit it into the side ring 4A.
Since the tank 1 has a rib 2A having an outer diameter larger than the inner diameter of one side ring 4A, the side ring 4A can be inserted to a position in contact with the upper portion of the rib 2A.
Since a space corresponding to the thickness of the side ring 4A is provided in advance between the rib 2A and the screw groove 3A, when one side ring 4A is attached, the screw groove 3A appears in a state of protruding above the side ring 4A. ..
A clockwise outward groove is formed in advance in the thread groove 3A of the tank 1. A clockwise and inward groove is also formed on the inner circumference of the fastener 8A. Further, since the upper surface of the tank 1 and the fastener 8A have a mark 12d indicating the right side, pay attention to the combination and attach the fastener 8A.
Then, when the fastener 8A is rotated clockwise in the direction of arrow A in FIG. 7, the tank 1 is fixed to the side ring 4A. However, at this point, the final tightening of tightening the fastener 8A and completely fixing the side ring 4A between the fastener 8A and the rib 2A is not performed. That is, the side ring 4A is temporarily fixed to such an extent that it can be slightly rattled.

Next, in order to attach the other side ring 4B (lower side of FIG. 7), the one side ring 4A for which the temporary fixing of the tank 1 has been completed is tilted to the right or left, and the side ring 4B is combined with the one side ring 4A. It is fitted into the insertion openings 6a (6b, 6c, 6d) at the same position from the lateral direction. The other side ring 4B also comes into contact with the rib 2B and stops at the lateral position of the rib 2B.
The thread groove 3B appears on the outer side surface of the side ring 4B due to the space corresponding to the thickness of the side ring 4B provided between the side ring 4B and the thread groove 3B.
A counterclockwise outward groove is formed in advance in the thread groove 3B of the tank 1. A counterclockwise inward groove is also formed on the inner circumference of the fastener 8B. Further, since the bottom surface of the tank 1 and the fastener 8B are marked for the left side, pay attention to the combination and attach the fastener 8B.
When the fastener 8B is attached and rotated counterclockwise in the direction of arrow B, the fastener 8B is fixed to the side ring 4B.
Finally, when the fasteners 8A and 8B are rotated again in the respective rotation directions to perform final tightening, the C-shaped insertion rubber 7a (6b, 6c, 6d) attached to the outer periphery of the insertion port 6a (6b, 6c, 6d) ( 7b to 7d) are compressed, and a repulsive force due to the elasticity of the rubber is generated to further enhance the adhesion to the side wheels 4A and 4B.

When the liquid storage device assembled in this way is assembled and used (transported), it is towed to the water supply station through a rope in the center hole 5, or a string created by breaking the bedding sheets or the like instead of the rope. Can be replenished with drinking water.
Further, when the tank 1 is used without being separated, the drinking water supply port 13c is installed at the lower part of the bottom surface of each tank 1, so that the tow is passed through the center hole 5 after adjusting the position of the supply port 13c. It is desirable to use it after ensuring safety so that it will not move against the will of the user by being trapped on a pillar or the like with a rope. When one tank 1 becomes empty and the next tank 1 is used, the rope is loosened and the supply port 13c of the next tank 1 is used so as to come to an appropriate position.

Further, when the elevator is stopped due to a power failure or the like in a condominium or the like, the tank 1 can be removed from the side wheels 4A and 4B, and the handle 12c can be gripped and carried up in a divided state. Considering the case where a single tank 1 is carried by hand in this way, it is desirable that the capacity of one tank 1 is about 18 liters or less.
The tank 1 of one embodiment uses a plastic resin, and among them, it is desirable to use high-density polyethylene in consideration of impact resistance as in the case of plastic tanks widely distributed in the market.

As described above, in one embodiment, the effects described below can be expected.
It is assumed that four tanks 1 will be mounted on the side wheels 4A and 4B, but since the side wheels 4A and 4B are disk-shaped, it is easy to balance the position of the insertion port, and the capacity and number of tanks to be mounted. It is possible to flexibly respond to redesign according to the situation.
It can be manufactured in large quantities using the resin materials and molding technology that are on the market without using special materials, and low cost can be expected.
Since the tank 1 and the side wheels 4A and 4B have a simple shape, standardization is easy and a large amount can be prepared and stockpiled.

Individuals and local governments stockpile emergency drinking water in preparation for a major earthquake that may occur in the future, but there are many manufacturers and the shapes of the stockpiled PET bottles and tanks are currently inconsistent. Is. For this reason, by adopting the shape of a tubular plastic tank as in one embodiment for the container and storing emergency drinking water, side rings, and fasteners, the waiting time of the water truck and the tank can be reached when water outage occurs. It is possible to quickly distribute to the victims with only a short installation time without waiting for the water supply time. In addition, since it is possible to transport multiple emergency drinking waters, the amount of distribution per person is limited, but it is possible to distribute to multiple victims, which leads to a reduction in the physical and mental burden on the victims.

The shape and capacity of the tank are not limited to the above-described embodiment, and the outer shape may be changed or the number of ribs may be increased or decreased depending on the wall thickness and capacity.
The number of insertion openings in the side ring is not limited to one embodiment. Further, by arranging the arrangements at equal intervals in the circumferential direction or symmetrically with respect to one diameter, it is possible to reduce the load during transportation by smooth rotation or to secure stability at the time of stopping. ..
The shape of the side ring is not limited to a disk, and may be a regular polygonal shape that approximates a circle. The regular polygonal side ring is inferior in circular diameter in smooth rotation, but has an advantage that it can be stopped stably.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like within a range not deviating from the gist of the present invention are also included.

The present invention can be used for storing and transporting liquids.
