Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device in which refueling equipment is housed on an island and a case is eliminated.

As is well known, there is a stand-type gas station (an island is set up on the premises of the gas station), where people come in and out for refueling.
It plays the role of C to make the running of the car smooth and to aim for zero stopping position PJ refueling error. The island is necessary for Te 41 itself as a gas station (
However, if there are too many people, the refueling T rear becomes narrow.
If it is too small, it will be difficult to target because it will cause trouble when driving.

For this reason, a refueling H1iff is known in which a case containing refueling equipment is installed on an island, and the island is kept at an appropriate size. In this way, we installed a case to store the refueling equipment in the eyeliner tote.
A car was driving over the island.
In the event of a collision with a vehicle, the refueling system will tilt and the refueling pipe inside the case will be damaged.
There is that. In conventional oil supply systems, even if the oil supply piping is damaged, the oil supply pump etc. are activated to continue refueling (°j), so oil may flow out from the damaged area and cause fire or other problems. There is a fear of causing trouble.)
Ta.

The present invention has been made in view of the above-mentioned drawbacks of the conventional oil supply device, and in case t9 of the oil supply device, if the oil supply exceeds a certain level, the oil supply will be stopped and the oil leakage can be prevented.
Nru refueling device 11? The purpose is to serve the public.

In accordance with the present invention, a refueling device equipped with a case housing refueling equipment on an island is equipped with a tilt detector, and when the detector detects a tilt of a certain level or higher, refueling is stopped. It is equipped with a control circuit.

Therefore, if the case tilts by more than a certain value due to an earthquake, etc., the tilt detector detects the tilt of Therefore, it is possible to completely prevent oil from flowing out from the damaged part of the oil supply pipe.

When implementing the present invention, τ, the angle of the tilt detector (= J location,
It is desirable to have the upper part of the case where the displacement due to inclination is greatest.

The tilt detector is installed on the platform where the nonos is tilted more than a certain level A]
Both the type that is in the state ff1t and the type that is turned on only when it is tilted can be used.

In the case where it is installed on island 1, the display section can be installed relatively far from the oil supply piping.
The first embodiment of the present invention will be described with reference to FIG. 1 and FIG. Ru.

To give an overview of the refueling system embodying the present invention, as shown in Figure 1, an island I is installed at a suitable location within the grounds of a refueling station, and the area around island I is a refueling area C.

It can be located in a so-called non-hazardous area, and therefore the electrical equipment stored therein need not be explosion-proof. First and second oil quantity indicators 114a and 4b are housed in the first case 1, and the electric wire 5 extending from these oil quantity indicators 4a14b passes through an airtight valve 120 of the case, and is connected to the airtight valve 112 of the case. The current is connected to the pulse generator. Each of these oil supply m display δ14a, 4b has 1151 built-in circuits. On the surface of the first case 1, an appropriate number of information boards 6 are further added to the information display section 7.
An oil type display section 9 is provided with a display board 8 for displaying the oil type.
It is equipped with A fluorescent light 10 is installed inside the first case 1 to make the display on these display sections 7 and 9 clear.

A is equipped with a tilt detector 20, the details of which are shown in FIG. The tilt detector 20 is attached to a mounting piece 2b on the upper part 2a of the case.
The entire explosion-proof case 21° (corrupted) is provided with a seat 21a that protrudes in a norange shape inside the explosion-proof case 21. , a container-shaped electrode 22 connected to a conducting wire 23 is seated.A lid body 24 insulated from the electrode 22 is attached to the F section of the container-shaped electrode 22. l'!+
14 rod-shaped electrodes 26 connected to l 25 pass through the lid 24. , 1-1 in FIG. 2 is a conductive liquid such as mercury, and the tip of the rod-shaped electrode 26 is immersed in the container-shaped electrode 22 (Pi!). It is being taken into account. Incidentally, m of the conductive liquid 1 is determined by the n volume inclination angle of the case 2.

Under normal conditions, that is, when the case 2 is not tilted, the electrically conductive liquid 11 is in contact with the tip of the rod-shaped mold 1M26, so that the wire 23, the container-shaped electrode 22, and the electrically conductive liquid 1-1 ,
The rod-shaped electrode 26 and the wire 25) constitute an open circuit (71
state). On the other hand, when tilting, that is, case 2 is constant (1)
If the slope is 7, the conductivity is 1! [The liquid 1-1 will be in contact with one side of the container-shaped electrode 22, so the liquid 11 will not come into contact with the rod-shaped electrode 26. 1, electrically conductive liquid) 1 is electrically disconnected from the rod-shaped pi 26, and an open circuit is created between IWA 23 and 25 (:4 state). FIG. 3 shows the circuit ll'W used in the first embodiment of the present invention.

The tilt detection p, +t 2 o, the nozzle switch 1G,
The excitation coil 30 is connected in series, and the excitation coil 30 constitutes a relay switch together with a contact point 32 between the drive pump 1M and a power source (not shown).

When the case 2 is not tilted (normally), the tilt detector 20 constitutes an open circuit and is in the OFF state. After that, remove the nozzle 1/I from the nozzle hook 1 no. 15 and turn the nozzle switch. If 16 is closed and conductive (on), the excitation I-il 30
When energized, the relay switch is in the on state and contact 3
2 is closed, current is supplied to the drive motor M, the oil supply pump P is driven, and the oil supply is ready. If the case tilts due to an earthquake or car collision, etc.)

In this 11, J is excited: When the current to the coil 30 is cut off, the C1 relay switch is turned off, the contact 32 is opened, and the drive motor Mb is stopped. As a result, the refueling pump]
) stops driving and oil supply stops, so even if the oil supply pipe is damaged due to the inclination of case 2, oil will not flow out.

In the embodiment described above, 113 circuits are normally configured and are in the off state, and when the case 2 is tilted around 1, the circuit is opened and the circuit is in the off state. However, the opposite form, that is, usually the A state'
C″ slope 1F, a slope that is ON only for Ir.

It is also possible to use a detector.

FIG. 4 shows a tilt detector that is turned on only when the vehicle is tilted.

The embodiment shown in FIG. 4 also has the same structure as that shown in FIG. 2, but the bell-shaped electrode 26 has a container shape.

A hole 1 is provided inside the container-shaped electrode 22 in a manner similar to that shown in FIG. .

Therefore, under normal conditions, the bell-shaped electrode 26 and the container-shaped electrode 22 are electrically disconnected, forming an open circuit (state (A)).

The electrode 2 is tilted 1°, and the 3N electrolytic liquid H is connected to the container-shaped electrode 2.

fQ25 is in electrical communication and forms a closed circuit (off state).

The circuit that includes the tilt detector used in Kihatsuro has an alarm! It is also possible to incorporate A buying. Referring to Figure 5,
-(The circuit incorporating the texting device will be explained next.)

20 in Figure 5 is usually +1. The above-mentioned tilt detector is in the A) state when the case is tilted, and is in the OFF state when the case is tilted, and is connected to the relay 42 via the normally closed return switch 40. /I/1146 is relay 4
This is the second point of contact. The C alarm device 48 is connected to the contact point /16 1), and the tilt detector 20 is connected to the relay 4 as shown in Fig. 3.
Replace it with a normally closed contact that opens and closes at zero.

In normal times, the tilt detector 20 is in an off state.

Therefore, the relay 42 is not energized, and therefore, when the nozzle 14 is removed from the nozzle hook 15 and the nozzle switch 1G is closed, refueling is performed and the alarm device I! l does not work. J for earthquakes or car collisions.

When the recovery case is tilted beyond a certain level, the tilt detector 20 is turned on, so the tilt detector 20 and the return switch 4 are turned on.
A current flows through the relay 42 through 0, and the relay 42 is excited. When this occurs, the contact /14.46 is turned off, the alarm device /I8 is activated by energization, the circuit of the motor M for driving the pump is opened, and the drive of the motor M is stopped. Even if the case 2 returns to its previous tilt position and the tilt detector 20 is turned off again, the relay 42 is self-held by the contact 44, the fuel supply is kept stopped, and the alarm device 48 is activated. Continue operation. After confirming safety and operating the recovery switch/IO to turn it off, the relay 42 is deenergized and the contact/IO is turned off.
Since I6 is turned off again, the alarm device 48 is stopped and refueling is possible again. If the case is tilted more than a certain meter like this, check the safety and turn the RL start switch 4.
Unless 2 is operated, refueling will be stopped and the alarm will be activated, ensuring greater safety. .

As described above, by the oil supply device according to the present invention,
If the case is tilted, the oil supply will stop (in fact, the oil supply pipe will be ruptured due to the tilt of the case), but oil will not leak out. This will ensure the safety of the J3 U'b gas station in the event of a collision.
