Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cover for a body case of an oil level gauge for an underground tank installed in a gasoline filling station or the like.

[Conventional technology]

For example, at a filling station that supplies fuel such as gasoline to cars, an oil storage tank is buried underground, and the oil is pumped up from the tank to a gasoline refueling machine installed above ground. An oil level gauge is installed in the manhole above the oil storage tank so that the amount of oil remaining in the tank can be seen at a glance from the ground, and leak checks and inventory management are performed.

An example of such an oil level gauge is one in which a tape that moves in conjunction with the vertical movement of a float installed in an oil storage tank is housed in the main body case and exposed through a viewing window, and the tape is provided with a scale to display the amount of remaining oil. The amount of oil remaining in the underground tank can be determined by reading the scale on the tape through the viewing window from above ground.

[Problem to be solved by the invention]

The main case is housed in a box called a manhole, whose top surface is flush with the ground surface, and since this manhole is located on the premises of a gas station, it is free from rainwater, car wash water, other particles, and dust. etc. often enter the manhole and cover the viewing window on the top of the main body case, making it difficult to read the scale clearly.

Therefore, as shown in FIG. 4, the top surface of the main body case 1 is covered with a lid 20 to protect the viewing window 9 from water, mud, and the like. This lid 20 is attached so as to cover the main body case 1, and has a structure in which it is completely removed from the main body case 1 when the lid is opened. Then, open the lid 20 and use the tape 4.
To prevent the lid 20 from being lost when checking the remaining oil level by reading the scale 3 of the
connected to.

Therefore, when the lid is opened, the lid 20 attached to the tip of the chain 21 hangs down inside the manhole together with the chain 21, and when the muddy water is turbid, it gets into the muddy water and becomes dirty, resulting in poor workability.

The purpose of the present invention is to eliminate the disadvantages of the conventional example, and to cover the upper surface of the main body case of an oil level gauge for an underground tank with a cover.
We provide a cover for the body case of an oil level gauge that not only prevents the lid from being lost when the lid is opened, but also allows for easy opening and closing of the lid, and can be applied to existing wavefront meters and body cases with slightly different diameters. It's about doing.

[Means to solve the problem]

In order to achieve the above object, the present invention is characterized in that an opening/closing lid is attached to a detachable band on the outer periphery of the main body case via a hinge part.

[Effect]

According to the present invention, when the band is wrapped around the upper part of the outer circumference of the main body case, the opening/closing lid attached to the upper part of the band via the hinge part is located on the upper surface of the main body case, and this opening/closing lid is visible on the upper surface of the main body case. cover windows. When checking the amount of remaining oil, the lid opens via the hinge. Therefore, when the lid is open, the lid is connected to the main body case via the hinge portion and the band, so the lid does not come off from the main body case and fall into the manhole, thereby preventing it from becoming dirty or being lost.

Further, since the position of the hinge can be changed by turning the hand horizontally on the outer peripheral surface of the main body case, the opening/closing direction of the lid can be set as appropriate, and the lid can be opened/closed in a direction that is easy to handle.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the cover for the body case of the oil level gauge of the present invention, and Fig. 2 is an explanatory view of the oil level gauge with the cover of the present invention attached. To explain the overall structure of the oil level gauge to which the oil level gauge is attached, the body case 1 of the oil level gauge is attached to the riser pipe 22 of the oil storage tank 10 exposed in a manhole 2 provided on the premises of a gas station or the like. This main body case 1 is formed into a cylindrical shape, and a tape 4 with a scale 3 indicating the amount of remaining oil is wound around the inside.
is arranged on one reel 5b, and the reel 5 is disposed on one reel 5b.
A reel 8 around which a cable 7 having a float 6 attached to its tip is wound is provided coaxially with the cable 8b.

A viewing window 9 is formed on the top surface of the main body case 1,
The tape 4 bearing the scale 3 is exposed through the viewing window 9, and the float 6 is suspended into the underground oil storage tank 10 and floated on the oil surface. Reference numeral 24 in the figure is an oil type display plate.

The cover of the present invention is attached to the main body case 1 of such an oil level gauge, and in the figure, 11 indicates a band made of elastic synthetic resin, and the band 11 has approximately the same diameter as the outer diameter of the main body case 1. Taber was also formed in a C-shape in almost the same way.

Anti-slip rubber 25 is placed on the side of this band 11 at appropriate locations.
A hinge member 12 is provided at an intermediate position, and the opening/closing 11 is attached above the band 11 via this hinge member 12.
3 will be provided. The opening/closing lid 13 has an inner diameter approximately equal to the outer diameter of the main body case l, is made of colored resin, and has an oil type indicator 23 written on its upper surface.

To attach the cover configured as described above to the main body case 1, simply insert the band 11 into the upper outer circumferential surface of the main body case 1, and by wrapping it around it, it will be relatively firmly fixed by the non-slip rubber 25. . In this state, the opening/closing lid 13 attached to the upper part of the band 11 covers the upper surface of the main body case 1 and covers the viewing window 9.

At this time, even if the outer diameter of the main body case 1 is somewhat larger than the diameter of the band 11, it is possible to attach it to the main body case 1 of such size by stretching the band 11 using its elasticity.

Furthermore, by turning the band 11 horizontally on the outer peripheral surface of the main body case 1, the relative position of the hinge member 12 with respect to the main body case 1 can be freely changed.
3. Set the opening/closing direction of No. 3 appropriately to a direction that is easy to handle.

Next, the usage and effect will be explained.

Open and close! 13 is closed, the opening/closing lid 13 covers the top surface of the main body case 1, and water and mud that have entered the manhole 2 adhere to the viewing window 9, making it difficult to read the scale 3 on the tape 4. prevent that.

To know the amount of oil remaining in the tank 10, open the cover of the manhole 2, open the opening/closing lid 13 of the cover by rotating it upward via the hinge member 12 (position shown by the chain line in Figure 2), and open the viewing window. 9 and read the scale 3 on the tape 4 from there. At this time, since the opening/closing lid 13 is connected to the main body case 1 via the hinge member 12 and the band 11, there is no fear that the opening/closing lid 13 will fall into the manhole or be lost during the remaining oil amount checking operation.

After checking the amount of remaining oil, the hinge member 12
The opening/closing lid 13 is rotated and closed via the opening/closing lid 13, and the viewing window 9 is covered again with the opening/closing lid 13.

Note that if piping or the like is installed inside the manhole 2 and it is difficult to open or close the opening/closing IE 13 because the piping or the like is an obstacle, pull out the band 11 upward from the main body case 1 and remove the band 1.
1 and the opening/closing lid 13 can also be removed from the main body case 1. In this case, since the band 11 is made of an elastic material, it can be easily attached and detached.

In the above-described embodiment, the opening/closing lid 13 is a colored opaque body, but it is not limited to this and may be made of a transparent body. In this case, the opening/closing lid 13 does not become dirty and maintains its transparent state. It is also possible to read the scale 3 by passing through the cover 13 without opening the cover 13.

Further, in order to clean the cover, the band-eye 1 can be easily removed from the main body case 1 by simply pulling it out from the main body case 1, so that the work efficiency is good.

〔Effect of the invention〕

As described above, the cover for the body case of the oil level gauge of the present invention allows the lid to be placed in a direction that is easy to open and close, making it easy to open and close, and preventing the lid from falling or being lost when the lid is opened.

In addition, it can be applied to existing oil level gauges and body cases with slightly different diameters, and even if there is no space to open and close the lid depending on the installation condition of the oil level gauge, the entire cover can be easily attached and removed, allowing a wide range of uses. It is.
