As a result, the functional unit in the protector 7 is protected from inadvertent behavior by a third party, so that an unexpected situation can be prevented beforehand and safety in gas supply can be achieved.

Further, as shown in FIG. 2, the gas supply unit 3 comprises a gas take-out valve 4, a supply device such as a regulator, and a gas meter 5 connected in series by a piping system 6. At this time, the piping system 6 is brought close to the gas extraction valve 4 so that the primary pressure gauge 8
The two-stage pressure-reducing integrated type regulator 9 and the screw gas stopper 10 with the inspection hole are sequentially arranged, and the piping between the gas stopper 10 and the gas meter 5 is connected to the side wall 71 of the protector 7. It is installed along the inner surface of the.
On the supply side of the gas supply unit 3, a pipe 13 leading out of the side wall 71 of the protector 7 is connected to the gas meter 5 and attached along the inner side surface of the side wall 71.

In FIGS. 1 and 2, reference numeral 14 denotes a detection unit of the gas alarm device, and reference numeral 15 denotes one end connected to the gas meter 5 and the detection unit 14 and the other end led out of the side wall 71. It is a resin flexible tube that houses signal lines.

As described above, the container main body 2 in which the gas supply unit 3 is disposed at the upper portion can be commonly used between an above-ground type and an underground type as shown in FIG.

That is, as shown in FIG. 3 (a), it can be installed on a foundation 20 placed on the ground as shown in FIG. 3 (a).
The upper part of the container body 2 is protruded above the ground as shown in (b), and is installed on a foundation 20 placed on the bottom of the hole 30 (semi-underground type), or as shown in FIG. The foundation 20 is placed at the bottom of the excavated hole, and is buried and installed so that the upper part of the protector 7 projects above the ground (underground type). In the case of a buried underground type (FIG. 3C), a storage box 31 for housing a terminal portion of a cathodic protection wiring (not shown) is protruded above the ground.

The container body 2 commonly used in this way is
A liquid inlet valve 16 and a liquid level gauge 17 are provided on the body 21 (FIG. 1).
) Or provided on the upper head plate 22 in the protector 7 (two-dot chain line in FIG. 2), and can be easily configured as an intermediate filling type or an upper filling type, respectively. In this case, the intermediate filling type bulk supply device 1 is dedicated as a ground type, and for example, the filling pipe of a tank truck can be easily connected to the liquid filling valve 16 depending on the installation position of the liquid filling valve 16. Workability can be improved. In addition, the top-filled bulk supply device 1 is used not only as an underground type but also as an above-ground type. That is, when used as an underground type, the liquid inlet valve 1
For example, the connection position of the filling pipe of the tank truck can be easily connected to the liquid inlet valve 16 depending on the installation position of the tank truck. When the ratio of L ₁ / height L ₂ is designed to be large and the position of the protector 7 is designed to be relatively low, the filling pipe is inserted from above the protector 7 and connected to the liquid inlet valve 16. Conversely, the capacity of the container main body 2 is increased, or the ratio of the diameter L ₁ / height L ₂ of the container main body 2 is designed to be small so that the position of the protector 7 is relatively high. When designed, the filling pipe can be inserted from the side of the protector 7 and connected to the liquid inlet valve 16.

As described above, the top filling type bulk supply device 1

The bulk supply device 1 configured as described above
Is designed so that the container body 2 can be shared between the above-ground type and the underground type, and the projected area is minimized because the body 21 of the container body 2 is formed in a vertical cylindrical shape. As a result, space can be saved by downsizing and installation space.

In addition, in this bulk supply device 1,
Since the gas extraction valve 4 is provided on the upper end plate 22, the gas extraction valve 4 can be provided vertically in a vertical direction avoiding a bent portion where reliquefied propane easily accumulates, whereby a stable supply of gas can be achieved. .

FIG. 4 shows a modification of the bulk supply device 1. This modified example is an example of application to a ground type, and the outer periphery of the cover 72 of the protector 7 is extended outward to form a
a and the cover 4 near the liquid inlet valve 16.
0 is provided with an earth plate 32. Note that reference numeral 33 in FIG. 4 is a ground wire.

In this modified example, the direct sunlight can be prevented from directly hitting the container body 2 by the cell part 72a, whereby the temperature rise of the container body 2 can be suppressed, and the re-liquefaction of the gas and the apparatus can be prevented. The safety of the whole can be achieved, and grounding from the tank truck during filling operation can be easily performed by the ground plate 32 provided near the liquid inlet valve 16.

FIGS. 5 and 6 show a modification of the protector 7. Both of the protectors 7 have split lid pieces 72b, 72c (72d, 7d) whose upper openings are independently opened and closed.

b and 72c are lightweight and have a small opening and closing radius, and can be easily operated. In particular, in the case of an underground type, the lid 72 is often made of a sturdy heavy material, and workability can be improved by configuring the lid 72 with the divided lid pieces 72b and 72c.

The lid 72 shown in FIG. 6 has a flat upper surface as a whole (see FIG. 6B), and the lid pieces 72d and 72e divided into two parts at the center are divided. The parts are connected by hinges 35. A handle portion 36 and a handle receiving portion 37 are provided on each of the cover pieces 72d and 72e, and the cover pieces 72d and 72e are centered on the hinge 35 by gripping and operating the handle 36. , And can be opened and closed independently of each other. In FIG. 6B, each lid piece 72d,
The opening direction of 72e is indicated by an arrow.

The handle portion 36 and the handle receiving portion 37 are shown in FIG.
As shown in (a), when one lid piece 72d (72e) rotates and overlaps with the other lid piece 72e (72d), the handle of one lid piece 72d (72e). 36 is provided while maintaining a positional relationship so as to overlap the handle receiving portion 37 of the other cover piece portion 72e (72d).

At this time, the handle portion 36 and the handle receiving portion 37
Are formed, for example, as shown in FIG. That is, the handle portion 36 is formed by bending a wire material into a substantially U-shape, and the handle receiving portion 37 holds two plate-like bodies 37b having a recessed portion 37a at the upper edge on the lid piece 72d (72e). Are formed so as to protrude in parallel.

The lid 72 in this modification is such that one lid 72d (72e) is opened and the other lid 72 is opened.
e (72d), the grip portion 36a of the handle portion 36 when overlapped
Is in contact with the recess 37a of the handle receiving portion 37 (FIG. 7).
(See (a)). In this state, the two plate-like members 37
b, 37b and the other lid piece 72e (7
Since the gap 41 is formed between the gap portion 2d and the holding portion 36a, the grip portion 36a can be easily gripped by using the gap 41 during the closing operation, and the opening and closing work of the lid portion 72 can be facilitated.

Further, as shown in FIG. 7 (b), the handle 36 is formed by recessing the center of the grip 36a.
May be formed to have the protruding portions 36b on both sides thereof.
The handle portion 36 thus formed does not require the handle receiving portion 37 in the above-described embodiment, and the above-described gap 41 can be formed by the handle portion 36 itself. Can be played.
