Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to an oil type discriminator for determining the type of oil to be refilled into an oil storage tank at a gasoline refueling station for automobiles and the like.

[Prior art and its problems]

Such gas stations sell many types of oil, such as regular gasoline, high-octane gasoline, diesel oil, and 1 oil, and these oils are stored in underground oil storage tanks for each /111 type.

Incidentally, oil is replenished from tank 1 to the oil storage tank at any time, but if different types of oil are injected (mixed oil), the mixed oil cannot be used, and oil is supplied from the underground tank. The mixed oil must be removed. Further mixed 1111
If you sell oil without knowing this, there is a risk of engine failure or abnormal combustion in your stove, so you must avoid mixing oil. To this end, it has been considered and is being implemented to install an oil type discriminator at the oil filler port of each oil storage tank.

The oil type discriminator uses a sensor that uses electricity to operate, but conventional oil type discriminators were powered from offices, etc. on the premises of the filling station, so It required extensive wiring work (-) and the cost was high, and even though the discriminator operated sufficiently with a small amount of electricity, it was connected to a large commercial 100 V electric pig iron.
The drawback was that it was associated with great danger, such as the risk of fire due to electrical leakage.

[L1 aspect of the invention] The object of the present invention is 11. I. Eliminates the disadvantages of the conventional example, extremely reduces the number of wiring parts, saves on land transportation, and makes it possible to make small power supplies independent by 1/8. Every time we provide an oil type discriminator that is less dangerous and can save power resources.

[Key points of the invention]

However, according to the present invention, this objective is achieved by connecting a solar cell for a drive power source to an oil type discriminator provided at an oil filling port of an oil storage tank at a gas station.

[Embodiments of the invention]

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

FIG. 1 is a partial perspective view of a filling station equipped with an oil type discriminator according to the present invention. 1", 1", . . . indicate an oil storage tank buried underground, for example, in a corner of the gas station premises, and injection pipes 2, 2',
2"... on the ground near the fire wall 7 of a gas station, for example, and connect the oil filler ports 3, 3 at the tips of the main pipes 2, 2', 2"...
°, 3''... are closed with a lid or automatic opening/closing valve.

The oil type discriminator 4 of the present invention has a device part of the main body 5 located at the oil filler port 3.3°, 3''.Means for determining the oil type include specific gravity, light transmittance, light transmittance, etc. There are devices that utilize different colors or natural frequencies and use various sensors to detect these.

As a power source for driving the oil type discriminator 4, a solar cell 6 is attached near the main body 5, for example, on the fire wall 7, etc., and the solar cell 6 is connected to the main body 5 by a wiring 14 via a storage battery 8.

Note that this storage battery 8 is used for solar cells 6 due to fluctuations in the amount of solar radiation.
It stabilizes fluctuations in electricity generation, such as on cloudy days and at night.
It can be used even when no light is irradiated.

Furthermore, an alarm device 9 is provided which is integrated with the solar cell 6 to notify the user of the injected oil by light or sound.

In the figure, 10 indicates a tank lorry, and 111 indicates the tank lorry.
10 refueling bowl is not shown.

Next, to explain the usage and operation, in order to supply oil from the tank lorry IO to the oil storage tank 1, the lorry
10 oil supply hose 11 to oil storage tank 1 IZI 3
Connect to and supply oil from the lorry 10 to the oil storage tank l.

When the oil injected from the lorry IO into the oil storage tank 1 passes through the oil filler port 3, the oil type 1' is detected by the oil type 1' and the oil injected from the lorry 10 into the tank 1. It is determined whether the oil is of the same type or not. At this time, the discriminator main body 5 is driven by the solar cell 6 as an energy source.

If the oil supply hose 11 of the lorry 10 is mistakenly connected to the oil filler port 3' of another oil storage tank 1' and the oil type is different, the discriminator 5 detects this, and the alarm 9 and tuning fork notify the user with light. do.

Therefore, when the worker learns that the oil supply hose 2 has been connected to the tank 11 containing different types of oil, he can immediately stop the oil supply to prevent oil mixture.

The above is the main body 5 of the discriminator installed at each oil filler port 3, 3', 3''.
One solar cell 6, storage battery 8, alarm 9 as a driving source
In the second embodiment, as shown in FIG. 2, in order to further reduce the wiring between each main body 5 and the solar cell 6, the solar cell 6,
What is necessary is just to provide the storage battery 8 and the alarm 9.

In this case, in the illustrated example, a support 11128 protruding from the discriminator main body 5 and a support rod 12 protruding from the lower surface of the solar cell 6 are used.
b are rotatably connected with a joint 13, and a storage battery 8 and an alarm 9 are provided adjacent to the solar battery (i).

If the solar cell G is installed obliquely so that the energy harvesting surface always rotates or automatically faces toward the sun, as the direction of sunlight irradiation changes, the solar cell 6 will also change direction through the contacts 1 and 13. It can be rotated and energy can be stored effectively.

[Effects of the Invention J As mentioned above, the oil type discriminator of the present invention uses a solar battery as its drive source, so there is no need to obtain power from a commercial power source such as a power line, so large-scale wiring work is not required. It is no longer necessary and construction costs can be reduced.

In addition, it is useful for saving energy sources, and since there is no need to use a large power source, it is possible to maintain safety by preventing fires from occurring due to electrical leakage.
