The design of the filling pipe generally needs to arrange an oil inlet pipe and a vent pipe at the same time, fuel oil flows in from a filling pipe cover and enters an oil tank through the oil inlet pipe, and then gas in the oil tank is discharged through the vent pipe. However, this method is highly demanding with respect to the placement of the tank and the relative position of the filler pipe. The filling pipe is used for filling fuel oil, the gravity of the fuel oil flows downwards, the filling pipe needs to be ensured to be continuously downward during design, the requirement on the relative position of a filling opening and an oil tank is high, meanwhile, a vent pipe needs to be arranged, air extruded after the fuel oil is added into the oil tank is timely discharged, and otherwise, the filling difficulty can be caused. The design of the vent pipe also needs to ensure that the vent pipe continuously faces upwards, a U-shaped section is not allowed, and the like, otherwise, fuel oil blocks the vent pipe, and the vehicle is not smoothly filled.
In addition, some vehicles may include two or more fuel tanks for increased range or for increased back-up safety fuel tank considerations. The arrangement of the filler pipe becomes more difficult due to factors such as spatial arrangement after the oil tank is increased. And usually one fill pipe per tank needs to be arranged. However, in this method, a plurality of fuel tanks are provided with a plurality of filler pipes, and the refueling action is repeated. Particularly when the fuel tanks are respectively arranged at two sides of the vehicle, the vehicle also needs to be moved so as to fill the fuel tanks with different measurements. And if the oil tank is arranged on one side, the filling pipe is arranged on the other side, which is difficult mainly due to insufficient gradient of the filling pipe, so that the filling is slow, and meanwhile, due to the arrangement influence of the whole vehicle, the filling pipe and the vent pipe from one side to the other side cannot be continuously arranged downwards, so that the situation of difficult filling due to U-shaped sections and the like can occur.

As shown in fig. 6, the system of the present invention works as follows: when fuel oil is filled, the oil pump controller judges which oil tank is currently used according to a signal of the switching valve, the control valve is switched to the current oil tank, fuel oil filling is preferentially carried out on the oil tank which is currently used, if the oil tank I1 is currently used, oil is preferentially filled into the oil tank I1, the controller continuously focuses on the oil tank to obtain a liquid level sensor signal, when a specified value is reached, the oil pump controller is controlled to switch to another oil tank, and at the moment, fuel oil is filled into the oil tank II 2. After the oil tank II 2 is filled, the fuel oil can be continuously gathered in the oil storage cavity, and the oil pump controller can timely stop the operation of the oil pump according to the information of the liquid level sensor in the oil storage cavity. When the oil storage cavity is full of oil, the oil gun can jump. The level sensor in the oil storage chamber plays oil pump rotational speed condition effect simultaneously for fuel keeps at reasonable liquid level in the oil storage chamber, promptly: if the oil filling amount is large, the oil pump is controlled to pump oil quickly, the oil pumping speed is reduced when the liquid level is reduced to a certain liquid level, the oil pump is prevented from idling, and stepless control over the oil pump is achieved. Meanwhile, a diesel defoaming mechanism is arranged in the oil storage cavity, so that the influence of foam on the oil pump is eliminated.
When the vehicle is not provided with the fuel tank switching valve, fuel in the fuel tank can be transferred through the fuel pump control valve. The main working process is as follows: if the oil tank I1 is a main oil tank and is connected with an engine, when the controller monitors that a liquid level sensor of the oil tank I1 is lower, the controller actively adjusts the control valve to conduct the oil tank I1 and the oil tank II 2, and fuel oil in the oil tank II 2 is pumped into the oil tank I1 through the oil pump. When the vehicle is provided with an oil tank switching valve, the system can be used when the switching valve is damaged; when the vehicle is not provided with the fuel tank switching valve, the transfer of fuel oil filled by a plurality of fuel tanks can be realized through the system. The system has no special requirements on the arrangement of the oil tank, and the diameter of an oil pipe of the oil tank communication control valve is greatly reduced due to the large pressure of the oil pump, so that the problem of diameter reduction can be solved through the flow velocity.
Namely, according to the aspect of the invention, the invention also provides an intelligent multi-oil-tank fuel filling method, which comprises the following steps:
the method comprises the following steps: the oil pump and control valve controller 9 judges the working state of the oil tank switching valve 12, if the oil tank switching valve 12 works normally, the step two is carried out, otherwise, the step three is carried out;
step two: the oil tank switching valve 12 sends a working signal to the oil pump and control valve controller 9, the oil pump and control valve controller 9 judges the working oil tank according to the working signal, if the working oil tank is the first oil tank 1, the oil pump and control valve controller 9 controls the control valve 805 to communicate the oil storage cavity 802 and the first oil tank 1, and the oil tank 1 is filled with the fuel oil, if the working oil tank is the second oil tank 2, the oil pump and control valve controller 9 controls the control valve 805 to communicate the oil storage cavity 802 and the second oil tank 2, and the oil tank 2 is filled with the fuel oil;
step three: the oil pump and control valve controller 9 controls the control valve 805 to communicate the first oil tank 1 and the second oil tank 2, so as to control the oil pump 804 to introduce the fuel in the first oil tank 1 into the second oil tank 2, or to introduce the fuel in the second oil tank 2 into the first oil tank 1.

The filling pipe system solves the filling problem of a plurality of oil tanks which are randomly arranged by arranging the oil pump, is not limited by the arrangement structure of the whole vehicle any more, can not meet the special arrangement requirement of the design of the filling pipe any more, and greatly increases the arrangement flexibility of the fuel tank. Meanwhile, the oil pump of the filling pipe system can automatically judge the filling condition according to the sensors of the respective oil tanks, automatically switch, preferentially fill the oil tank according to the currently used oil tank under the condition of multiple oil tanks, and can pump the fuel pump in one oil tank to another oil tank under specific conditions or economic conditions, and if a certain oil tank is damaged and leaks oil, the damaged oil tank can be pumped to the good oil tank through the system. Similarly, the fuel tank pipeline connection can be simplified, the engine only absorbs oil from one fuel tank, and when the oil quantity of the fuel tank is less than a specific volume, other fuel tanks can be automatically pumped into the fuel tank through the system.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
