Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device for use in gasoline refueling stations for automobiles and the like.

In such a suspension hose type refueling device, in which the refueling hose is suspended from a canopy, a refueling pump for sending oil to each refueling hose, a refueling motor, and a flow meter for the flow meter are installed in a place called a pump room. They are usually set up in groups.

By the way, a total counter with a return button that displays the total amount of refueling for the day and returns to zero at every daily check, a so-called daily counter, and a total counter that displays the total amount of refueling, and a total counter without a return button has the above-mentioned flow rate. These pumps are directly connected mechanically to the pump room, and you must go to the pump room to view them for record-keeping purposes when opening or closing the store.

However, the pump room is often located in a corner of an inconvenient location such as the back of a building, and is small and dark, making it troublesome to look at each of the counters.

The purpose of the present invention is to solve the disadvantages of the conventional example,
To provide a lubricating device that installs a daily counter and a total counter in the control panel to improve the efficiency of counter reading work, and that can be installed at low cost because existing devices or parts can be used. be.

However, according to the present invention, the purpose of the lever is to provide a hose elevating device for a refueling hose having a nozzle valve at the tip in the canopy, raise a pipe communicating with an underground tank, and connect it to the refueling hose within the hose elevating device. , a pump and a flow meter are installed in the middle of this piping, a flow rate pulse transmitter is installed on the flow meter, and this flow rate pulse transmitter is connected to a refueling amount display meter via a control device such as an electronic circuit in a control panel. In the type refueling system, this is achieved by providing a total counter for the amount of refueling in the control panel, connecting this total counter to the control device, and forming a viewing window for viewing the total counter in the lid of the control panel. be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which an embodiment of the present invention is implemented in a hanging hose type oil supply device will be described in detail below with reference to the drawings.

Fig. 1 is a longitudinal side view showing a hanging hose type oil supply device, Fig. 2 is an enlarged front view of main parts showing an embodiment of the present invention, in the figure 1 is a canopy, 2 is an office connected to the canopy, 3 indicates the wall, and 4 indicates the pump room.

A fuel supply pipe 5 communicating with an underground tank (not shown) is connected to a fuel pump 6 and a flow meter 7 in the pump room 4.
It is installed outdoors via the A refueling motor 8 is connected to the refueling pump 6.

Similarly, in the pump chamber 4, a flow rate pulse transmitter 9, a total counter 10, and a daily counter 11 (a counter for counting the daily amount of oil supplied) are mechanically connected to the flow meter 7. In the figure, 11a is a return button of the daily counter 11.

The refueling pipe 5 extends over the wall 3 and the canopy 2, enters a hose processing device 12 suspended from the canopy 2, and connects to a refueling hose 14 wound around a hose reel 13, which is a hose lifting device.
The refueling hose 14 hangs from the hose reel 13, and is provided with a nozzle valve 15 at its tip, and a lowering switch 16 and an ascending switch 17 for the refueling hose 14 are attached near the nozzle valve 15.

In the hose processing device 12, a motor 18 and a cam switch 19 for detecting the position of the nozzle valve 15 from the winding state of the refueling hose 14 are connected to the hose reel 13.

Terminals of these switches 16, 17, motor 18, cam switch 19, refueling motor 8, and pulse transmitter 9 in the pump room 4 are connected to a control panel 20 installed in the office 2, and an electric A terminal for an oil supply amount indicator 32 is also arranged on the control panel 20.

The details of the control panel 20 are shown in FIG. 2. The control panel 20 is constructed by attaching an opening/closing lid 20c to the front opening of a metal box 20a with a hinge 20b.

In the figure, 21 is the wiring to the commercial AC power supply, 22 is the wiring to the refueling motor 8 and pulse transmitter 9, and 23 is the wiring to the refueling amount indicator 32, the motor 18 in the hose processing device 12, the cam switch 19, etc. Wiring 2
1 is connected to a relay circuit etc. 25 via switches 24, 24', 24'' which serve as main power switches in the control panel 20, and this relay circuit etc. 25 is connected to an electronic circuit etc. 26.
It is connected to wirings 22 and 23 via.

The electronic circuit 26 includes a total counter 27 and a daily counter 2 provided in the control panel.
Counter sets 29, 29', 29'', . . . for each oil supply device consisting of 8 combinations are connected.

A flow rate signal from the pulse transmitter 9 is introduced into the electronic circuit 26, and conventionally, the signal is processed and transmitted to the display meter 32 to display the amount of oil supplied. In the present invention, a flow rate signal is transmitted to each counter 27,28. The total amount of refueling is displayed.

Furthermore, a viewing window 30 fitted with a transparent plate 30a is provided on the lid 20c of the control panel 20 so that each counter 29, 29', 29''... can be seen from the outside, and a lock 31 is installed on the box body 20a and the lid 20c. The lid 20c was prevented from being opened by anyone other than those involved.

In this way, the flow rate signal from the flow rate pulse transmitter 9 provided in the flow meter 7 of each refueling device drives the total counter 27 and daily counter 28 via the electronic circuit etc. Just look at it.

As described above, the oil supply system of the present invention has a daily counter and a total counter for the amount of oil supplied in the control panel, which eliminates the need to go to inconvenient locations such as the pump room, and the control panel can be opened and closed. Since the main power switch is always touched when opening and closing the store, you only need to look at each counter at that time.Furthermore, the counters can be observed through the viewing window installed in the control panel lid, so there is no need to touch the main power switch to open or close the lid. It is something you only need to look at soon, and it prevents you from forgetting to look at the counter.

Furthermore, there are signal lines and electronic circuits inside the control panel that transmit the flow rate signal from the flow meter to the refueling amount display meter, so if you use this, you can simply set up a counter and connect it to the electronic circuit, and you will not need to do any other special work. It does not require any wiring or equipment and can be manufactured at low cost.
