Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example 1: Reference Figure 1-Figure 5A new energy filling device for ships comprises: a liquid phase pipe 1, a gas phase pipe 2 and a loading arm 3, wherein the loading arm 3 is connected to a tank truck via a liquid phase pipe 1 and a gas phase pipe 2, a batch controller is provided on the mounting skid of the tank truck, the batch controller is electrically connected to a mass flow meter and a mass flow meter 2 via a wire, the batch controller is electrically connected to a flow control valve and a flow control valve 2 via a wire 2, the mass flow meter and the flow control valve are arranged in the liquid phase pipe 1, and the mass flow meter 2 and the flow control valve 2 are arranged in the gas phase pipe 2.

[0026] The principle of the above scheme is:

[0027] Fuel is stored in the tank truck. The loading arm 3 is connected to the fuel tank of the ship. First, nitrogen is used to replace the air in the loading arm 3. The liquid phase pipe 1 and the gas phase pipe 2 are opened. The "loading precooling" button is pressed on the batch controller. The batch controller slowly opens the flow regulating valve and the flow regulating valve 2 to 5% of their opening to precool the loading arm 3. The mass flow meter and the mass flow meter 2 respectively measure the mass of the fuel liquid and the fuel gas output to the loading arm 3. When the mass of the fuel liquid and the mass of the fuel gas input into the loading arm 3 by the liquid phase pipe 1 and the gas phase pipe 2 reach the preset value, the loading arm 3 is completely frosted under the action of the low-temperature fuel liquid and the fuel gas. The "fast loading" button is pressed on the batch controller. The batch controller slowly opens the flow regulating valve and the flow regulating valve 2 to the set normal loading flow. When the loading volume reaches 95% of the set loading volume, that is, the fuel When the loading volume reaches 95% of the bunker loading volume, the batch controller slowly closes the flow regulating valve and the flow regulating valve 2 to the set small flow, continues to replenish the fuel to the fuel bunker until the fuel in the fuel bunker is full and the loading is ended, and at the same time closes the liquid phase pipe 1 and the gas phase pipe 2, and then disconnects the loading arm 3 from the fuel bunker; when the loading volume reaches the loading advance amount, the batch controller closes the flow regulating valve and the flow regulating valve 2, and at the same time closes the liquid phase pipe 1 and the gas phase pipe 2, and then disconnects the loading arm 3 from the fuel bunker; after disconnecting the loading arm 3 from the fuel bunker, the operator purges the arm 3 with nitrogen respectively; the specific model of the batch controller is: DZHB-08; the mass flowmeter and the mass flowmeter 2 are the same device, and the specific model of the mass flowmeter is: F300; the flow regulating valve and the flow regulating valve 2 are the same device, and the specific model of the flow regulating valve is: ZDLP.

[0028] The beneficial effects of the above scheme are:

[0029] A mass flow meter and a flow regulating valve are arranged on the liquid phase pipe 1, and a mass flow meter 2 and a flow regulating valve 2 are arranged on the gas phase pipe 2. The batch controller controls the mass flow meter and the flow regulating valve through a wire. The batch controller controls the mass flow meter 2 and the flow regulating valve 2 through a wire 2, and can accurately control the filling flow of the fuel in the ship's fuel tank and monitor the filling process in real time.

[0030] Fuel is simultaneously input to the loading arm 3 through the liquid phase pipe 1 and the gas phase pipe 2, and the loading arm 3 fills the fuel into the fuel bin, thereby increasing the speed of fuel filling.

[0031] Example 2: Reference Figure 1-Figure 5 A pneumatic shut-off valve is provided in the liquid phase pipe 1, and a pneumatic shut-off valve 2 is provided in the gas phase pipe 2. The pneumatic shut-off valve and the pneumatic shut-off valve 2 are both electrically connected to the batch controller through a wire 3.

[0032] The principle of the above scheme is:

[0033] After completing the nitrogen replacement of the air in the loading arm 3, the pneumatic shut-off valve and the pneumatic shut-off valve 2 are opened through the batch controller, and the fuel in the tank truck is input into the loading arm 3. After completing the loading, the pneumatic shut-off valve and the pneumatic shut-off valve 2 are closed through the batch controller.

[0034] The beneficial effects of the above scheme are:

[0035] A pneumatic shut-off valve is arranged in the liquid phase pipe 1, and a pneumatic shut-off valve 2 is arranged in the gas phase pipe 2, so that the fuel in the tank truck can be sealed before and after loading to prevent leakage.

[0036] Example 3: Reference Figure 1-Figure 5 The liquid phase tube 1 is provided with a temperature transmitter, and the gas phase tube 2 is provided with a second temperature transmitter. Both the first temperature transmitter and the second temperature transmitter are electrically connected to the batch controller through a fourth wire.

[0037] The principle of the above scheme is:

[0038] The specific model of the temperature transmitter is: RS485. The temperature transmitter and the temperature transmitter 2 are the same device. When the loading arm 3 is completely frosted under the action of the low-temperature fuel liquid and the fuel gas, the temperature transmitter feeds back an electrical signal to the batch controller to prompt that the pre-cooling of the loading arm 3 is completed.

[0039] The beneficial effects of the above scheme are:

[0040] A temperature transmitter is set to monitor the temperature of the loading arm 3 and feed back to the batch controller to prompt the operator to use the batch controller to perform the next operation. This can avoid the operator from observing the degree of frost near the loading arm 3, further improving the safety of the operator when working on the device.

[0041] Example 4: Reference Figure 1-Figure 5 The liquid phase pipe 1 is provided with a pressure transmitter, and the gas phase pipe 2 is provided with a second pressure transmitter. The pressure transmitter and the second pressure transmitter are both electrically connected to the batch controller through a wire five.

[0042] The principle of the above scheme is:

[0043] The specific model of the pressure transmitter is: SCH-31. The pressure transmitter and the pressure transmitter 2 are the same device. The pressure transmitter is provided in the liquid phase pipe 1, and the pressure transmitter 2 is provided in the gas phase pipe 2. The pressure transmitter and the pressure transmitter 2 can monitor the pressure status in the liquid phase pipe 1 and the gas phase pipe 2 in real time, and feed back to the batch controller in real time.

[0044] The beneficial effects of the above scheme are:

[0045] The pressure transmitter and the second pressure transmitter can monitor the pressure in the liquid phase pipe 1 or the gas phase pipe 2 in real time and display it on the batch controller. When a leak occurs in the device, an early warning can be given to avoid the leakage from expanding, further improving the safety of the device during operation.

[0046] Example 5: Reference Figure 1-Figure 5 One end of the electrostatic controller is provided in the tank car, the end of the electrostatic controller extending outside the tank car is connected to the end of the grounding device, and the other end of the grounding device is connected to the ground.

[0047] The principle of the above scheme is:

[0048] The specific model of the electrostatic controller is: SCP-SA. One end of the electrostatic controller is set in the tank truck and in contact with the fuel in the tank truck. When static electricity is generated in the device, the static electricity can be uniformly collected by the electrostatic controller and neutralized by the grounding device.

[0049] The beneficial effects of the above scheme are:

[0050] The use of an electrostatic controller can neutralize the static electricity in the fuel in the tank truck, further improving the safety of the device during operation.
