[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an outdoor sign light device, and more particularly to a structure having an excellent maintenance property that can be applied to, for example, a lid of an existing fire hydrant provided on a road and can be easily replaced even if the sign light is damaged.

[0002]

[Prior art]

 Recently, when fires occur, fire hydrants are increasingly required for fire fighting water sources. For such fire hydrants, it is common to lay a fire extinguishing water facility below the road and cover the upper side with a lid.

[0003] Usually, a fire hydrant lid is made of a casting and has a three-dimensionally formed fire hydrant character on its surface, or a lid colored yellow or the like. If there is no fire hydrant, it will be difficult to find the hydrant, and if it is covered with earth and sand, it will be particularly difficult to find it.

[0006] Therefore, various marker lamp devices have been proposed in which a light emitting body such as a solar cell and a light emitting diode and an energizing circuit are built in a lid of a fire hydrant (for example, Japanese Utility Model Laid-Open Publication No. 03-65770, and JP-A-03-116500, JP-A-05-79066, JP-A-06-39052, JP-A-11-30965, and the like.

[0005]

[Problems to be solved by the invention]

 However, despite the fact that the number of fire hydrants reaches almost 1.3 million when viewed nationwide, there are few fire hydrants equipped with beacon lights.

[0006] The present inventors have conducted various studies on the sign light device, and as a result, the sign light device described in the conventional publication does not have a structure that can be retrofitted on an existing lid, but any of the conventional devices has a cover equipped with the sign light device. It was necessary to manufacture them, and they came to realize that this was a factor that hindered the spread of fire hydrant marker lights.

[0007] In view of the above, the present invention provides an outdoor sign light device that is excellent in maintainability such that it can be used for a lid of an existing fire hydrant and can be easily replaced even when the sign light is damaged. As an issue.

[0008]

[Problem to be solved]

 Therefore, the outdoor sign light device according to the present invention is a sign light device that is retrofitted to an existing lid installed outdoors, and is formed by perforating a lid made of a weldable material. And a circular mounting hole formed in a size that does not reduce the strength of the lid, and made of a weldable material, inserted into the mounting hole, and the upper end of the upper end is almost flush with the lid. A cylindrical mounting case with a bottom fixed between the edge and the periphery of the mounting hole by welding; a resin sealing body inserted into the mounting case so as to be substantially flush with the lid; A marker light circuit sealed by a stationary body and including at least a solar cell and a luminous body that emits light by the solar cell.

One of the features of the present invention is that a mounting hole is drilled in a lid, a mounting case is fixed to the mounting hole by welding, and a resin sealing body containing a marker lamp circuit is inserted into the mounting case. It is in the point which was made.

[0010] This makes it possible to equip the lid of the existing fire hydrant with the indicator light device by the simple operations of drilling and welding. In addition, when the device is deteriorated such as when the luminous body is damaged, the mounting case can be removed by cutting the welded part with a grinder or the like, so that the marker lamp circuit can be replaced every time the resin sealing is performed, and maintenance is easy. As a result, it is expected that beacon lighting devices can be spread without increasing costs.

[0011] The mounting hole may be formed in a square shape, but cracks are formed in the square corners, and there is a concern that the strength of the lid itself may be reduced. On the other hand, in the present invention, since the mounting hole is formed in a circular shape, there is no possibility that a crack is formed in the periphery of the mounting hole, and the strength of the lid can be guaranteed.

Since the upper edge of the mounting case is welded flush with the lid, there is no danger that the mounting will be dislodged even if the vehicle is stepped on by the wheels of the vehicle. Also, the resin sealing body is inserted flush into the mounting case. As a result, even if the wheels of the vehicle step on the resin sealing body, there is no danger of the sign lamp circuit being seriously damaged, and the reliability of the device can be guaranteed. According to the tests of the present inventors, it was confirmed that durability of about two years can be guaranteed.

[0013] The upper edge of the mounting case and the peripheral edge of the mounting hole may be welded linearly over the entire circumference, or may be welded in a dotted shape if the welding strength can be ensured. The welding method is not particularly limited, but a gas welding method or the like is preferable in view of work on site.

Further, in the present invention, the mounting case is directly welded to the mounting hole of the lid, but a cylindrical, ring-shaped or other mounting base is fixed to the mounting hole side by welding, and the mounting case is fixed thereto. The same operation and effect can be obtained by screwing.

That is, the outdoor sign light device according to the present invention is a sign light device that is retrofitted to an existing lid installed outdoors, and is formed by perforating a lid made of a weldable material. A circular mounting hole sized so as not to reduce the strength of the lid, and made of a weldable material, fixed to the periphery of the mounting hole by welding, and formed at least one female screw portion on the peripheral wall; A mounting base in which mounting screws are screwed into at least one female screw portion, and an upper end thereof is inserted into the mounting base so as to be substantially flush with the lid, and is mounted on the mounting base by the mounting screws. A bottom cylindrical mounting case, a resin sealing body inserted into the mounting case so as to be substantially flush with the lid, sealed with the resin sealing body, and provided with a solar cell and the solar cell. hand And a marker light circuit including at least a luminous body that emits light.

The outdoor sign light device according to the present invention has a great effect when applied to a fire hydrant cover, but the same applies to a fire protection water cover, a gas inspection port cover, and a water and sewage manhole cover laid on a road. To apply.

Although a cylindrical case with a bottom is used as the mounting case, a flange may be formed on the upper edge of the mounting case all around or intermittently, and the flange may be temporarily fixed by being hooked on the circumference of the mounting hole. .

Considering the mechanical characteristics of the lid of a fire hydrant actually installed on a road, it has been confirmed that it is better to drill a hole having an inner diameter of 45 mm to 85 mm.

The temperature of the fire hydrant inside the poorly ventilated fire hydrant rises to around 100 ° C. under hot summer weather, and if this is transmitted to the sign lamp circuit, the circuit may be thermally degraded. Therefore, it is preferable to interpose a sheet-like heat insulating material between the mounting case and the resin sealing body.

If the resin sealing body is manufactured to a size that is almost perfectly adhered to the mounting case (or the sheet-like heat insulating material), the air between the resin sealing body and the mounting case does not escape, so that the insertion and replacement can be performed. It becomes difficult. Therefore, it is preferable to form a small hole for venting air on the bottom surface of the mounting case.

[0021]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on a specific example shown in the drawings. 1 to 4 show a preferred embodiment of the outdoor sign light device according to the present invention. In the figure, a lid 10 is a lid that is pivotally supported on the upper edge of a fire hydrant and a water supply manhole so as to be openable and closable, and is manufactured in a rectangular shape using a casting.

Fire hydrant and water supply letters 11 and 12 are formed three-dimensionally on the surface of the lid 10, and two holes are drilled on the lower side of the lid 10, and the two holes have a U-shaped lifting Both ends of the member 13 are slidably inserted, and a stopper portion is formed at the tip of the member 13 to prevent the member 13 from falling off. By lifting the lifting member 13 upward, the lid 10 can be lifted. I have.

In the vicinity of the lower side of the lid 10, the marker light device 20 of the present embodiment is provided. In the indicator light device 20, the cover 10 has a mounting hole having an inner diameter of 45 mm or more, preferably 50 mm (when the cover 10 is large, it is 85 mm or less, preferably 80 mm). The mounting case 21 is inserted and fixed in the mounting hole.

The mounting case 21 is made of, for example, stainless steel and has a cylindrical shape having an outer diameter and fitted into a mounting hole of the lid 10, and a small hole 25 for venting air is formed in the bottom surface. The mounting case 21 is fitted into the mounting hole of the lid 10, the upper edge thereof is made substantially flush with the peripheral edge of the mounting hole, and the space between the upper edge of the mounting case 21 and the peripheral edge of the mounting hole is linearly welded over the entire circumference. I have. 1 and 2, reference numeral 24 denotes a welded portion.

A resin sealing body 22 is inserted into the mounting case 21 so as to be substantially flush with the lid 10, and a sheet-like heat insulating material 23 is interposed between the resin sealing body 22 and the mounting case 21. Has been established. A silicon resin material can be used for the heat insulating material 24.

For example, the marker lamp circuit shown in FIG. 4 is resin-sealed in the resin sealing body 24. The sign lamp circuit of this example generates a current in response to sunlight and generates an electric current and has a function of an illuminance sensor. It is composed of a day / night switching unit that turns on the display unit at night, an intermittent signal generation unit that blinks the display unit at set time intervals, and a display unit that includes light emitting diodes. Note that the present invention is characterized by the mounting structure of the marker light device, not the marker light circuit. Therefore, the marker light circuit is not limited to the circuit configuration of FIG. 4, and other circuit configurations can be adopted. . K

When installing the marker light device of the present embodiment, the fire hydrant and the existing cover 10 of the waterworks manhole are removed and transported to the factory, where the mounting hole is drilled using a drilling machine and brought back to the site. Next, the mounting case 21 is inserted into the mounting hole of the lid so as to be flush, and the entire periphery between the upper end edge of the mounting case 21 and the peripheral edge of the mounting hole is welded with a welding rod by gas welding or the like. Is welded linearly over The filler rod should be compatible with both castings and stainless steel.

After the mounting of the mounting case 21 is completed, the heat insulating material 23 is set on the inner surface of the mounting case 21 and the resin sealing body 22 is pushed in, and the air in the mounting case 21 escapes from the air vent hole 25 on the bottom surface. Therefore, the resin sealing body 22 can be mounted in the mounting case 21, and thus the indicator lamp device can be easily mounted on the lid 10.

When the marker lamp device is replaced after a predetermined period of time, for example, the welded portion 24 on the upper edge of the mounting case 21 is shaved by a grinder or the like, and a shock is applied using a hammer or the like. Since it is easily removed from the mounting holes 10, the remaining welded portion 24 may be ground with a grinder, and then the mounting case 21 may be welded in the same manner as described above to set the heat insulating material 23 and the resin sealing body 22.

Also, when it is necessary to replace only the resin sealing body 22 for some reason, if the resin sealing body 22 is pushed up by inserting a tool such as a screwdriver through the air vent hole 25, the resin sealing body 22 may be removed from the mounting case 21. Therefore, a new resin sealing body 22 may be set in the mounting case 21.

FIGS. 5 and 6 show the second embodiment, and the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. The marker light device of this example is different from the first embodiment in the following points. That is, the mounting base 26 is fitted into the mounting hole so as to be substantially flush, and the space between the upper end edge of the mounting base 26 and the peripheral edge of the mounting hole is welded and fixed linearly or dotwise over the entire circumference. I have.

The mounting base 26 has a cylindrical shape, and a screw hole (female screw portion) 28 is formed in the peripheral wall at an appropriate angular interval in the circumferential direction, and a mounting screw 27 is screwed into the screw hole 28. ing. Note that an insertion hole and a weld nut may be employed instead of the screw hole.

The mounting case 21 is fitted into the mounting base 26, and the mounting case 21 is mounted on the mounting base 26 by screwing a mounting screw 27 and pressing against the outer peripheral surface of the mounting case 21. .

When the above-described structure is adopted, the replacement of the mounting case 21 can be performed even more easily.
