Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an oil type confirmation device for tank trucks, and is independent of the surrounding environment.
The purpose is to enable safe and accurate transparent confirmation of the type of oil passing through the pipes.

[Conventional technology]

Conventionally, when unloading from the tank of a tank truck to the underground tank of a gas station, extreme care was taken to avoid unloading a different type of oil into the underground tank where the type of oil was specified. Various measures were taken to confirm the type of oil in petroleum products. In this case, one method is to provide a viewing window near the piping outlet of the tank lorry and visually confirm the type of dyed oil. The viewing windows used in this case are equipped with natural light transmission windows and viewing windows at two locations, either on the top or bottom or on the sides, and are used to confirm the type of oil that has been colored in a specific color using external natural light. Ta.

[Problem that the invention attempts to solve]

However, in bad weather, in the shade, or at night, there is a lack of natural light or a light source, and it may be difficult to see through the oil. In some cases, the color may take on a different hue, leading to a risk of erroneous confirmation.

[Means for solving problems]

This idea was created in view of the above-mentioned circumstances, and uses a light transmission system such as an optical fiber cable that transmits the light emitted from the light source body installed in the tank truck body to a light transmitting body formed at the end of the tank truck piping. A reflecting member having a body and reflecting light introduced into the piping through the transparent body, and a viewing window at a portion where the light reflected by the reflecting member reaches the piping are respectively provided in the piping. The present invention proposes an oil type confirmation device for a tank lorry, which is provided to visually confirm the type of specific oil passing through the pipe.

[Effect]

In this invention, a viewing window with a transparent material such as glass is formed at the end of the pipe of the tank truck, and the inner wall surface of the pipe end, which is almost opposite to the viewing window, is designed to make it easier to check the color of the transmitted light. , a reflecting member that reflects transmitted light is disposed, and a light source body located at a position separated from the pipe end is provided at the end of the pipe that substantially faces the reflecting member, and a light source body that transmits the transmitted light emitted by the light source body is provided. Tank truck oil that allows the type of oil passing through the piping to be safely and accurately confirmed at all times using transmitted light that has a relatively long transmission distance from a light source such as a fiber cable. This provides a species confirmation device.

〔Example〕

Embodiments of this invention will be described in detail below based on the accompanying drawings.

Fig. 1 is a schematic side view of a tank lorry equipped with the oil type confirmation device of this invention. A pipe 4 for unloading the liquid in the tank 2 is formed at the bottom of the tank 2 . An oil type confirmation section 5 that constitutes the oil type confirmation device of this invention is formed at the discharge side end of this pipe 4, and a light source section 6 that constitutes the oil type confirmation device together with this oil type confirmation section 5. It is arranged at a position separated from the oil type confirmation part 5 on the chassis 3 constituting the tank truck main body, connected to the battery 7, and arranged in the light source box 8.

As shown in FIG.
A hole 1 is formed diagonally downward in the upper part of the tubular oil type confirmation part 5 that connects to the discharge pipe 9 having a
A transparent body 13 such as glass or acrylic having a presser member 12 is disposed on 1 to form a viewing window 14, and a presser member 16 is inserted into a hole 15 bored diagonally at the bottom almost facing the viewing window 14. In addition, a reflecting mirror 18, which is a reflecting member, is disposed on a transparent body 17 made of glass or acrylic, etc., and in close contact with its outer surface.
A transparent body 21 made of glass or acrylic or the like is disposed with a presser 20 in a hole 19 diagonally formed toward the reflecting mirror 18 in the diagonally upper part that is almost opposite to the mirror 18 . In order to emit transmitted light, the light source box 8 and this transparent body 21 are connected by a light transmitting body 22 such as an optical fiber cable. That is, upon receiving the light from the lamp 23, which is the light source body disposed in the light source box 8 and emitted from the battery 7,
The light passing through the light transmitting body 22 is transmitted through the light transmitting body 2.
1, reflected by the reflecting mirror 18 at the diagonal lower part, and then passing through the transparent body 13 located at the upper part.Using this phenomenon, the type of oil dyed in a specific color passing through the inside of the pipe is detected. It is now possible to see through.

Note that 24 is an electric wiring that connects the battery 7 and the lamp 23, 25 is a lamp switch provided on this electric wiring 24, and 26 is a connection between the light transmitting body 22 and the light source box 8 or the oil type confirmation unit 5. It is a joint.

In the above embodiment, a case has been described in which the lamp 23 is used as the light source body, but a light emitting diode may be used instead of the lamp 23.

When confirming the oil type of the liquid in the piping with the oil type confirmation device of this invention configured as described above,
When the lamp switch 25 is turned ON and the lamp 23 emits light, the light from the lamp 23 passes through the light transmitting body 22 to the transparent body 2 on the upper part of the oil type checking section 5.
1 and is introduced into the pipe 4. The light passes through the oil passing through the pipe 4, is reflected by the reflector 18, and reaches the viewing window 14 at the top, so the oil type can be confirmed by visually observing the hue of the oil type in the oil in the pipe 4. It is possible.

[Effect of idea]

As explained above, according to the oil type confirmation device of this invention, the oil type can be confirmed by transmitting the oil in the piping under certain conditions regardless of the surrounding situation using light with a certain amount of light. By specifying the hue or wavelength of the light from the light source, it is possible to capture the dyed oil in a hue that is different from natural light and is easier to distinguish.Furthermore, the light from the light source can be reflected once by a reflecting mirror. By passing the oil over a longer distance, the difference in hue appears more clearly in the transmitted light, making it easier and more accurate to determine the type of oil. Moreover, according to the oil type confirmation device of this invention, the light source body and the battery that makes it emit light can be placed in a position separated from the end of the pipe, and the light source body and the upper part of the oil type confirmation part can be connected using an optical fiber cable. Even if the oil in the tank is a petroleum product, it is safe and secure, as it prevents the effects of heat from the light source and explosions due to leakage current. This has the excellent effect of allowing accurate visual confirmation of the type of oil.
