Description

[Detailed Description of the Invention] This invention relates to a water tank for loading and transporting, for example, on the loading platform of an automobile.

In order to water fields, orchards, etc., it is sometimes desirable to put water in a tank and transport it on a small truck, etc., but conventional car water tanks are made of FRP instead of iron plates, and the tank is heavy. Therefore, loading and unloading onto trucks is not easy.
It is unsuitable for use as a vehicle-mounted water tank for agricultural work, etc.

In addition, when this type of water tank has a small amount of water stored, a space is created inside the tank, and when the vehicle starts or stops, water moves within the tank, and when the brakes are applied, for example, water hammer shock is generated when the vehicle faces forward. In addition, it also has disadvantages such as accelerating the vehicle and impeding safe driving.

This idea was made in order to provide a water tank that eliminates the various drawbacks mentioned above. By constructing the water tank with a flexible watertight sheet, the weight is reduced and it is easy to load and unload into a vehicle. The purpose is to prevent water hammer shock caused by soil removal when starting and stopping the vehicle, and to lower the center of gravity and improve stability, leading to safe driving.

That is, the feature of the present invention is that a cylindrical sealed seat bag made of a flexible watertight sheet has an opening at the top inside the seat bag, penetrates from the inside of the seat bag to the outside, and extends to the outside. An exhaust passage that opens a small exhaust hole is provided, and a closing means is provided in the exhaust passage system to open the passage when water is injected and close it when water is drained. A water supply and drainage passage is provided that vertically penetrates the outside, and an opening that opens in the horizontal direction is provided in at least a part of the tip of the water supply and drainage passage that projects inside the seat bag, so that water is supplied and drained through the water supply and drainage passage. That's the point.

Embodiments of this invention will be described in detail below based on the drawings.

In each of the figures, reference numeral 1 denotes a seat bag made of a rubber sheet or other suitable deformable honeycomb sheet, and the seat bag 1 has a cylindrical shape and is sealed by closing both ends with stop plates 2 and 3.

Reference numeral 4 denotes a communication plug that penetrates the upper surface of the seat bag 1 and is attached to the upper surface, and this communication plug 4 connects a large diameter water supply and drainage passage 5 and a small diameter drainage passage 6, as shown in FIG. The lower ends of each of the water supply and drainage passage 5 and the exhaust passage 6 form an open lower part 8 above the inside of the seat bag 1, while the upper end of the water supply and drainage passage 5 has two T-shaped openings. 9,1
The exhaust passage 6 opens at 0, and is configured so that water can be supplied and drained through the passage via a communication member as appropriate, and a small exhaust hole 11 is also opened at the upper end of the exhaust passage 6.

Note that the opening 8 of the exhaust passage 6 is located above the open lower part of the water supply and drainage passage 5.

One unit of the water tank of this invention is constructed as described above, and when a plurality of water tanks are placed side by side, each water tank should be placed with the side on which the connecting plug 4 is attached facing upward as shown in FIG. Seat bags 1 are installed side by side on the loading platform and placed next to each other.
For example, a communication means consisting of a communication plug 4 and a communication pipe 13 is used, and the two directions of the communication plug 4 are interconnected by the flexible communication pipe 13.

Further, the small exhaust holes 11 of the communication plugs 4 of each seat bag 1 communicate with each other through a pipe 14 as shown in FIG. 16 to the atmosphere.

Therefore, when water is not stored in each of the seat bags 1 arranged side by side (or when the amount of water is small), the third
As shown by the two-dot chain line in the figure, the seat bag 1 has been reduced to a flat shape.

Therefore, when water is supplied from the communication tap 4 using a water pump 17 or the like, each seat bag is filled with water, and the seat bag 1 is filled with water.
expands into a cylindrical shape.

At this time, the air inside the seat bag 1 passes through the exhaust passage 6,
Furthermore, it passes through a valve 15 and a check valve 16 and is released into the atmosphere.

When the above-described operation is performed, water passes through the two ports of the communication tap 4 and is supplied to each seat bag 1 via the pipe 13, so that each seat bag 1 is filled with an appropriate amount of water.

In this state, each seat bag 1 is transported to a farmland, orchard, etc. by vehicle 12 and pumped out by a pump (not shown).
The water is discharged through the water supply and drainage passage 5 of the communication tap 4, and watering is performed.

In this case, since a check valve 16 is provided in the exhaust passage system, atmospheric air does not flow into the seat bag 1.
Therefore, as the exhaust progresses and the amount of water in the seat bag 1 decreases, the seat bag 1 shrinks into a flat shape as shown by the two-dot chain line in FIG.

In this case, if the opening lower of the water supply and drainage passage opens only downward, it may stick to the seat bag and make it impossible to drain water.Since the opening lower also opens horizontally, this adsorption effect during drainage can be prevented.

Of course, even if a separate communication stopper for water supply is provided, the opening of the communication stopper for drainage needs to open in the horizontal direction.

As the seat bag 1 shrinks as described above, the vehicle 12
Even when the vehicle is started or stopped, water does not move inside the seat bag and therefore does not cause water hammer shock to the vehicle.

In addition, in the above-mentioned embodiment, the communication plug is provided on the top surface of the seat bag, and this communication plug also serves as the water supply and drainage port to the seat bag, but the communication plug and the water supply and drainage port may be provided separately, or the communication Instead of a plug, the ρ side surface near the bottom surface of the seat bag 1 may be connected to each other by a joint 18 having a communication hole in the center as a water supply and drainage passage, as shown in FIG.

In this case, the top surface of each seat bag 1 is connected to an appropriate connecting plate 1.
9, and the water supply/drainage port 20 only needs to be provided in the outermost seat bag.

The water supply/drainage port 20 may have the same structure as the communication plug shown in FIG. 4, and may be constructed so that one of the two ports is closed with a plug 21 and water is supplied and drained from the other.

Note that 22 is an exhaust plug equipped with a small exhaust hole.

FIG. 8 shows another embodiment of the sheet bag, in which two flexible watertight flat sheets having a heat-fusible synthetic resin layer are used, and the sheet is formed into parallel strips with an appropriate pitch by high-frequency heating means. By welding them together 23 and further applying high-frequency heat welding 23 to the four peripheral edges, an integral seat bag having a plurality of chambers connected to each other is formed.

As a communication means for each chamber, heat welding is omitted only at an appropriate position in the middle of the parallel strips, and this unwelded portion is used as a communication path.

As described in detail above, since the water tank of the present invention is constructed from a flexible watertight seat bag, the weight of the water tank itself is reduced, making it easy to load and unload onto a vehicle, making it suitable for use on ordinary trucks and small-sized vehicles. By placing the water tank of this invention on the bed of a truck, it can easily be used as a water sprinkler truck, and when not being used as a water truck, the tank can be taken down to transport regular cargo, making the vehicle versatile. can be used.

In addition, the water tank of the present invention has an exhaust passage, which opens at the top inside the seat bag, and penetrates from the inside to the outside to reach the small exhaust hole. The air is expelled, making it possible and easy to supply water in a sealed state, and the lower end of the water supply and drainage passage has a horizontal opening in part, so when draining water,
Drainage can be carried out smoothly without the flexible sheet bag being adsorbed and obstructing the drainage action.

Moreover, since multiple seat bags can be arranged in parallel using appropriate communication means, handling becomes easier if the seat bags are divided into multiple parts, and by increasing or decreasing the number of seat bags, the capacity of water that can be transported can be increased or decreased as appropriate. Since the seat bag is flexible, it can be bent as shown in FIG. 5 according to the size of the vehicle's cargo bed, and has the advantage that it can be used regardless of the size of the vehicle's cargo bed.

Furthermore, since water hammer shock does not occur when the vehicle starts or stops, as described above, it is possible to drive safely.

Furthermore, the present invention has various advantages, such as being easy to manufacture, inexpensive, and lightweight, as well as having a lower center of gravity than the tank type, which improves the stability of the vehicle.

Note that the water tank of the present invention is particularly suitable for use in agricultural work.
