Abstract

PROBLEM TO BE SOLVED: To dispense with driving of an engine even in a long-time work and operate safely and efficiently by providing a pump system driven by an external power supply in a liquid supplying vehicle. SOLUTION: A tank lorry constituted of an oil feeding car body 1 and a fuel transfer tank 2 is remodeled by attaching an oil feed hose 3, a pump system 4, a meter 5, and an external power supply connecting receptacle 7. A reel 6 for winding the external power supply connecting receptacle 7 is attached thereto so as to prevent it from interfering the traveling. An oil feed pipe 13 connected to the pump unit 4 is connected to the tank lorry pipe part 14. The oil feed pipe 13 may be connected to anywhere in the tank lorry pipe part 14. The oil feed pipe 13 and the pump system 4 are positioned lower than the fuel transfer tank 2 so that a check valve 15 with a spring 15, etc., is attached thereto to stop the fuel so that the weight of the fuel in the fuel transfer tank 2 is prevented from directly applying to the pump system 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a liquid supply vehicle.

[0002]

2. Description of the Related Art In a conventional liquid supply vehicle, a pump is driven by an engine of a liquid supply vehicle main body, or a pump is driven via a motor by a power supply of the liquid supply vehicle main body to supply liquid.

[0003]

In a conventional liquid supply vehicle, since the pump is driven by the engine of the liquid supply vehicle main body, it is inevitable to drive the engine of the liquid supply vehicle main body at the time of liquid supply. Must continue to emit exhaust gas. or,
Since the motor is driven by the power supply of the liquid supply vehicle main body, it is not possible to supply liquid while the engine that generates power is stopped for a long time.

The exhaust gas emitted by the engine is not only unpleasant for the person who supplies the liquid or those around him, but also when used in a factory or the like, the exhaust gas becomes full and adversely affects the human body.

[0005] Further, an engine or an exhaust pipe which is heated due to lack of a cooling effect by traveling is dangerous when the liquid is flammable.

Since power is taken from the engine of the main body of the liquid supply vehicle, the structure becomes complicated, and it takes a long time and a large amount of cost to manufacture the liquid supply vehicle.

[0007] Even if it is a trailer type,
It cannot be completely divided.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a pump system driven by an external power source in a liquid supply vehicle without relying on power or electric power from a liquid supply vehicle main body. Accordingly, the engine may be stopped during the liquid supply, the vehicle body structure becomes simple, and a liquid supply tank facility that can be completely separated from the vehicle body can be made.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A motor for driving a pump is compatible with 100 volts or 200 volts.
An outlet corresponding to the number of volts is attached to the end of the power cord leading to the motor.

[0010] At the time of liquid supply, an outlet of a liquid supply vehicle is inserted into an outlet outlet inside or outside the building to take in electric power and supply the liquid.

The motor and other electric equipment should be of explosion-proof type in order to avoid the risk of electric leakage, as well as when handling flammable liquids.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings of an integrated small aircraft refueling vehicle constructed in accordance with the present invention.

In FIG. 1, a tank truck composed of a refueling car main body 1 and a fuel transport tank 2 is remodeled into a refueling car by attaching a refueling hose 3, a pump unit 4, a meter 5, and an external power supply connection outlet 7. .

An external power supply connection outlet 7 is provided with a reel 6 for winding up so as not to hinder running.

In FIG. 2, a fuel tank 13 connected to a fuel tank 13 is connected to a fuel tank 13 connected to the pump system 4.

The oil supply pipe 13 may be connected to any part of the tank lorry pipe 15 if safety and durability are not hindered.

Since the fuel supply pipe 13 and the pump system 4 are located lower than the fuel transport tank 2, the check valve 16 with a spring is attached so that the weight of the fuel in the fuel transport tank 2 does not directly apply to the pump system 4. Stopping fuel.

It is also possible to use a float type stopper instead of a check valve to stop the fuel.

[0019]

According to the present invention, a long period of time and a large amount of cost have been required for the manufacture of a liquid supply vehicle. However, according to the present invention, it is possible to manufacture the vehicle in a short period of time and at a low cost, and it is possible to sell a small amount of the liquid and use it for private use. For example, even if the use of a liquid supply vehicle has been abandoned in terms of cost, work can be performed safely and efficiently using the liquid supply vehicle.

Since there is no need to drive the engine even for long hours of work, it is not only environmentally friendly, but also can be used in factories and the like without polluting air.
