Background

Patent CN201077759Y discloses an automatic oiling device, which is mainly applied to power vehicles. Typically, the supply vehicle has a fuel-powered generator set for providing electrical power in a field environment without mains electricity. The fuel generating set is generally provided with an oil tank independently, and is different from an engine oil tank of a power supply vehicle, the oil tank of the power generator is generally higher in ground clearance position and smaller in operation space, and when a gas station refuels, a person needs to hold a refueling gun to enter the vehicle to refuel the oil tank of the power generator, so that great inconvenience is caused. In the patent, a pipeline extends out of the oil tank of the generator, and the transition oil tank is arranged at the tail end of the pipeline, so that oil is directly filled into the transition oil tank when the oil is filled, and the oil is pumped into the oil tank of the generator through an auxiliary oil filling pump, so that the position of the transition oil tank can be lowered when the oil is filled, the height of an oil filling port is reduced, and personnel do not need to enter the vehicle when the oil is filled.

When the power supply vehicle works in the field, the generator set works for a long time to cause insufficient oil, so the power supply vehicle also needs to refuel a generator oil tank in the field. But different from the refueling of a gas station, the field environment has no oil gun and only can carry an oil tank, and then oil in the oil tank is sucked into a generator oil tank by utilizing a separate pump and a hose. In this patent, although the auxiliary fuel pump and the transition tank are provided, they do not have the function of absorbing the oil in the tank. If additional pumps and hoses are additionally arranged, more internal space of the vehicle is occupied, and the control system is more complicated, so that the vehicle is inconvenient to modify. Therefore, how to refuel in the field under the premise of ensuring that the oil filling port is lower becomes a problem to be solved urgently.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

In describing embodiments of the present invention, the terms "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and other terms are used in an orientation or positional relationship shown in the associated drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Referring to fig. 1, a structure diagram of a single-pump multi-way refueling device according to an embodiment of the present invention is shown. This device includes gasoline pump 1 and transition oil tank 2, and the two is connected through main line 3, still is equipped with lateral conduit 4 on main line 3 (being located between gasoline pump 1 and the transition oil tank 2), and lateral conduit 4 one end is connected main line 3, and the other end opens. As can be seen from fig. 1, one end of the main pipeline 3 is connected to the generator oil tank 7, and the transition oil tank 2 is connected to the other end thereof (the fuel filler pump 1 is disposed on the main pipeline 3 and between the transition oil tank 2 and the generator oil tank 7). Therefore, when in oiling, the transition oil tank 2 is directly oiled, and then the oiling pump 1 arranged on the main pipeline 3 conveys oil to the generator oil tank 7, so that the indirect oiling is completed. The advantage of this is that the generator tank 7 is not easily moved, and the peripheral equipment formed by the transition tank 2, the main pipe 3 and the fuel pump 1 can be freely positioned. For example, the transition oil tank 2 can be fastened to the girder of the chassis by means of a screw connection (the fuel filler pump 1 can also be arranged on the girder in the same way), so that it is arranged relatively low and can be arranged outside. Therefore, when the vehicle refuels at a gas station, a worker holding a refueling gun can directly refuel the transition fuel tank 2 with a lower position without entering a carriage, so that the defect that the refueling is inconvenient due to the higher position of a fuel filler opening of a generator fuel tank is overcome.

But the flow of the petrol pump 1 cannot be matched exactly to the flow of different petrol guns. If the nozzle flow is greater than the flow of fuel filler pump 1, if do not set up transition oil tank 2 and directly refuel the pipeline and can make fluid spill over, cause pollution and waste. Therefore, the transition oil tank 2 needs to be arranged for buffering, so that when the transition oil tank 2 is about to be filled, a worker can temporarily stop the oiling action of the oiling gun and refuel again after the liquid level in the transition oil tank 2 drops.

In addition, the oil filling ports of the generator oil tank and the engine oil tank of some vehicles are not located on the same side of the vehicle, so that the vehicle needs to turn around to fill the other oil tank when filling at a filling station. The refueling device is applied to the mobile emergency power supply vehicle, and the special vehicle is generally applied to the occasions of emergency rescue, so that the turning-around action is extremely time-consuming for the limited space of a gas station and the huge vehicle body of the power supply vehicle, and does not meet the requirement of quick response. However the utility model discloses a transition oil tank 2 in the device sets up the position very nimble, even the oil filler hole of the generator oil tank of the vehicle that needs the repacking and engine oil tank is really not in same one side, also can set up transition oil tank 2 at the oil filler hole homonymy with engine oil tank to make the vehicle when filling station refuels, need not to turn round and can refuel for these two oil tanks, greatly practiced thrift the time.

In summary, the main pipeline 3, the gasoline pump 1 and the transitional oil tank 2 are matched to finish the gasoline filling work of the vehicle at the gasoline station, however, the structure can not fill the gasoline in the field. Therefore, the utility model discloses branch pipeline 4 has still been set up on main line 3. As shown in fig. 1, a branch line 4 is provided between the transition oil tank 2 and the fuel pump 1. Thus, when the vehicle works in the field, the branch pipeline 4 can be inserted into oil liquid in the oil storage device (oil tank or oil drum), and the gasoline pump 1 is started to suck out the oil liquid from the oil storage device. It follows that the branch line 4 is preferably a hose for ease of handling.

In order to avoid branch pipeline 4 and main line 3 to interfere with each other, the utility model discloses set up first control valve 5 and second control valve 6 respectively on main line 3 and branch pipeline 4. Wherein the first control valve 5 is located between the transition tank 2 and the branch line 4, whereas in the present embodiment both control valves are ball valves. As set forth above, when the vehicle is being refueled at the refueling station, the second control valve 6 can be closed, the first control valve 5 can be opened, the refueling pump 1 can be opened, and then the worker refuels the transitional fuel tank 2 by using the refueling gun. When the vehicle works in the field, the first control valve 5 is closed, the second control valve 6 is opened, the branch pipeline 4 is inserted into an oil tank or an oil drum in which oil is stored, and the oiling pump 1 is opened for oiling. For convenient control, a corresponding liquid level sensor can be arranged to monitor the liquid level of the generator oil tank 7 and timely control the oiling pump 1 to stop rotating when the oil is full.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
