Description

[Detailed Description of the Invention] What is uninvented about tank trucks, especially their fart oil prevention equipment? Regarding '7.

Generally, the tank mounted on a tank lorry is divided into multiple tank rooms by partition walls, and several types of oil are poured into each tank room separately at an oil depot, transported to a nearby oil filling station, and then filled with each type of oil. It can be adapted to suit the storage tank.

In this way, in a tank truck, a plurality of oils are loaded in one 16m tank, while the storage tanks at the oil refinery also have +M units corresponding to the mantissa oil, so there is more oil than the onboard tank. When refueling the tank, there were cases where the bottom valve of the installed tank opened due to a misoperation of the bottom valve of the tank, which had a different type of oil than the one in the storage tank, resulting in an oil mixing accident.

The present invention has been made in view of the above points, and its main purpose is to provide a tank truck that has a simple structure and can reliably prevent oil mixing accidents by focusing on the sexual cost of perfume oil. shall be.

The oil loaded in tanker trucks is mainly gasoline, diesel oil, and kerosene, and the specific gravity (15
, /4°0) is 0.71 to 0.75 for gasoline, 0.78 to 0.86 for diesel oil, and 0.81 to 0.84 for kerosene (the specific gravity of diesel oil and kerosene may be the same). Kerosene (white kerosene) is colorless, and diesel oil is pale yellow or pale brown.

In other words, gasoline and xm@light music can be distinguished by their specific gravity,
Furthermore, light oil and kerosene oil can be distinguished by color, so if we focus on this point, we can see that IJ is capable of distinguishing between tm fii oil and other oils.

Hereinafter, the configuration of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a tank truck, and a tank 2 having a plurality of tank ports (four in this example) is installed at the rear of the tank truck. It is installed.

The installed tank 2 is connected to a manhole/I/6 which is an oil filling port, a bottom valve 4 which is a discharge valve, a wiping valve (not shown) and a nozzle valve 4 for the valley tank chamber. A handle 40 is self-installed.

Each tank room of the onboard tank 2 is equipped with a sensor (i5), the detector 5 is connected to a control box 6, and the control box O- has an oil type display a.
7 is connected (the oil type indicator 7 is installed at an appropriate location such as the driver's seat, the tower, or on the side or above the tank 2).

75. In addition, transparent tube 50
Position sensors 56 and 54 made by former dragon officials and the like are placed above and below (3) to detect the position 1u of the float 51 and transmit it to the control box 6. Reference numeral 55 is an optical sensor that transmits the amount of light that is a hot spot to a control box 6 via a potentiometer and a meter 56, and the control box 6 stores in advance the amount of light transmitted by light oil and kerosene. I'll keep it. It is recommended that each device be explosion-proof.

To explain the oil type indicator 7, the oil type (gasoline, kerosene, diesel oil) is displayed on the display board 70 according to each tank chamber, and the control box 6 is displayed according to the detection result of the detector 5.
The oil press part indicated by will light up.

Another embodiment of the oil 81 indicator 7 may be a combination of a rotary disk displaying each type of oil and a display window.Next, the operation of the present invention will be explained. When oil is loaded in the tank chamber and the control box 6 is operated to activate the detector 5, the oil type is determined as follows according to the oil type.

(1) In the case of gasoline...specific gravity (15/4 °0)
is in the range of 0.71 to 0.75, and the specific gravity of Danjo oil is 0.
．． 74 or less, the float 51 is in a submerged state below the transparent tube 50, and the position sensor 56 is ON, and the position sensor 54 is OFF.If the specific gravity is 0.75, the float 51 is in a floating state and the position sensor 55 is .54 are both ON, and when the specific gravity exceeds 0.75, the 70-t 51 floats up to the upper end of the transparent bone 50, the position sensor 56 is OFF, and the position sensor 54 is ON.

+sl, the float 51 floats up and the position sensor 56 becomes O.
It can be determined that when IF Fs times b4 is ON, the 41 oil is not gasoline, and at other times it is gasoline.

(2) In the case of kerosene/light oil... When the float 51 floats up in the above (1), the oil being carried is kerosene or light oil, and in this case, the optical sensor 55 determines.

That is, since kerosene is transparent in color, a large amount of light passes through it, and the potentiometer and meter 56 operate greatly and transmit the light to the control box 6. Furthermore, light oil is light yellow or light brown in color and has a smaller light transmission cover than kerosene, so the potentiometer 56 operates less.

On the other hand, the m4 determined as above for each tank room is sent through the control box? It is displayed on the 1I11 type display 7.

Note that the detector 5 operates not only when loading, but also at the filling station 6. It may be activated for the first time when desired, such as during refueling.

Add some oil seeds! It is also possible to combine a control device that allows only the tank chamber loaded with i to be opened.

As described above, according to the present invention, since the detection means for detecting the type of oil in the tank mounted on the vehicle and the display means for displaying the detection result are provided, the type of oil heavily loaded is always displayed in the tank. This matches the internal oil level, preventing operator errors and improving reliability during refueling.
