Description

Description: TECHNICAL FIELD The present invention relates to an oil type discriminating device for discriminating the type of oil to be replenished in an oil storage tank of a gasoline filling station for automobiles and the like.

[Conventional technology]

Such a gas station sells many kinds of oils such as regular gasoline, high octane gasoline, light oil, and kerosene, and these oils are put in an underground oil storage tank for each oil type.

By the way, the oil is replenished from the tank truck to the oil storage tank at any time, but if oils of different oil types are injected (mixed oil), the mixed oil cannot be used and the oil mixed from the underground tank is used. Must be removed. Furthermore, if oil is sold without knowing the mixed oil, there is a risk of engine failure and abnormal stove combustion, and mixed oil must be prevented. Therefore, it is considered and is being implemented to provide an oil type discriminating device at the oil filling port of each oil storage tank.

[Problems to be Solved by the Invention]

The oil type discriminator operates a sensor using electric power, but since the conventional oil type discriminator obtains power from an office or the like on the premises of the gas station, the concrete on the premises is picked up and the wiring is performed. Required large-scale wiring work, and the construction cost increased,
Moreover, although the discriminator operates sufficiently with a small amount of electric power, it is connected to a large electric power of 100 V for commercial use, and there is a drawback in that there is a great danger such as a risk of a fire due to an electric leakage.

The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, to reduce the construction cost by significantly reducing the wiring portion, and to be independent with a small power supply circuit, so that there is little danger, and the solar cell can be adapted according to the installation situation. It is an object of the present invention to provide an energy-saving type oil type discriminator that can efficiently generate electric power and save power resources by solar power generation.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a main body of an oil type discriminating machine using a sensor in the vicinity of an oil filling port at the tip of an injection pipe rising from an oil storage tank buried underground, and the body of the oil type discriminating machine is rotated. A solar cell with a flexible joint and a storage battery and an alarm is integrally mounted on the body of the oil type discriminator by this joint, and the solar cell is used as a drive power source for the oil type discriminator via the storage battery. The gist of the invention is to connect this oil type discriminating machine to the main body.

[Action]

According to the present invention, since the oil type discriminator and the solar cell are integrated through the supporting rod, the wiring cost can be extremely reduced, the construction cost can be reduced, and the power source circuit can be independent. There is little danger, and since solar cells are used as the drive power source, power resources can be saved.

In addition, since the solar cell is rotatably supported via the joint, the solar cell is also rotated via the joint when the irradiation direction of the light beam changes depending on the installation situation, and the energy generated by the solar power generation is changed. Accumulation can be done effectively.

Furthermore, since the solar cell is used as the drive power source for the oil type discriminator, the power energy is consumed only when refueling the fuel, and other sunshine hours are stored in the storage battery that is integrated with the solar cell. .

As described above, since the oil type discriminator operates only during refueling, it does not consume much electric power energy, and thus the solar cell may be small in size. At this time, since the solar cell and the storage battery are integral with each other, it is not necessary to separately provide wiring, the probability of leakage is reduced, and safety is improved.

Then, the oil type discriminating device discriminates the difference in the oil type, and the alarming device warns by sound or light.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a reference diagram showing the entire inside of a gas filling station to which the oil type discriminating device of the present invention is attached. In the drawing, 1, 1 ′, 1 ″, ... A tank is shown, and an injection pipe 2 from the oil storage tank 1, 1 ′, 1 ″ ...
2 ′, 2 ″ ... is erected on the ground, for example, near the fire wall 7 of the gas station, and the lubrication ports 3, 2 ′, 2 ″ ...
3 ', 3 "... Are closed by a lid or an automatic opening / closing valve.

The oil type discriminating machine 4 of the present invention is one in which the equipment part of the main body 5 is attached to the lubrication ports 3, 3 ', 3 "..., As means for discriminating the oil type, specific gravity, light transmittance, color , Or utilizing various sensors having different natural frequencies and using various sensors to detect them.

As a power source for driving the oil type discriminator 4, as shown in FIG. 2, the solar cell 6 is located in the vicinity of the main body 5, and the main body of each discriminator is used to reduce wiring between the main body 5 and the solar cell 6 as much as possible. The solar cell 6, the storage battery 8 and the alarm 9 may be integrally provided for each 5.

In this case, the supporting rod 12a protruding from the discriminator main body 5 and the supporting rod 12b protruding from the lower surface of the solar cell 6 are connected by a rotatable joint 13 so that the storage battery 8 is adjacent to the solar cell 6. And the alarm 9 is integrally provided.

Therefore, if the solar cell 6 is installed obliquely so that the energy collecting surface always always faces the direction of the sun manually or automatically, as the irradiation direction of the solar rays changes, the solar cell 6
Also rotates through the joint 13 to effectively store energy.

The storage battery 8 is the solar battery 6 due to the fluctuation of the solar radiation amount.
It stabilizes the fluctuation for power generation and can be used even when it is not exposed to sunlight such as a cloudy day or night.

Further, a notification device 9 for notifying different oils by light or sound when injected is provided integrally with the solar cell 8.

In the figure, 10 is a tank truck, and 11 is an oil supply hose of the tank truck 10.

Next, the usage and operation will be described. To add oil from the tank truck 10 to the oil storage tank 1,
The oil supply hose 11 is connected to the oil supply port 3 of the oil storage tank 1 to supply oil from the lorry 10 into the oil storage tank 1.

The oil injected from the lorry 10 into the oil storage tank 1 is passed through the lubrication port 3 to the lorry 10 at the oil type discriminating machine body 5.
It is determined whether the oil injected from the tank is of the same oil type as that in the tank 1. At this time, the discriminator body 5 drives the solar cell 6 as an energy source.

The refueling hose 11 of the lorry 10 is mistakenly used for another oil storage tank 1 '.
If the oil type is different, connect to the oil filling port of
Detects this, and the notification device 9 notifies by sound or light.

Therefore, the worker who knows that the oil supply hose 11 is connected to the different oil tank 1'can stop the oil supply immediately and prevent the mixed oil.

〔The invention's effect〕

As described above, since the oil type discriminator of the present invention uses the solar battery as a drive source, it is not necessary to obtain power from a commercial power source such as a power line, and large-scale wiring work is not required, so that the construction cost can be reduced. You can

Also, since it does not require the use of a large power source, it is possible to secure safety such as prevention of fires due to leakage of electricity, and moreover, the solar cells can be efficiently generated according to the installation conditions, and solar power generation can save power resources.
