The float 6 can be used to seal the connecting pipe 7 under the influence of the buoyancy of the fluid when overflowing. By opening the solenoid valve 10, the excess fluid can be discharged from the overflow pipe 11, thereby preventing fluid overflow, reducing fluid waste, avoiding safety hazards, and ensuring the life safety of operators.

[0027] The working principle of this embodiment: when in use, first start the motor 16 according to the height of the tank truck, drive the screw 14 to rotate, and prompt the slider 17 to drive the crane pipe to adjust the height up and down as a whole. Then, use the first rotary joint 22 and the second rotary joint 24 to rotate and adjust the first conveying pipe 1, the first connecting elbow 21, the second conveying pipe 2 and the second connecting elbow 23 and other pipe sections to complete the docking of the vertical pipe 3 with the tank truck, and then connect the fluid from the liquid inlet pipe 19 to transport the fluid to the tank truck. Finally, when the delivery volume reaches the standard, the internal pressure of the crane pipe increases. At this time, the pressure cut-off valve 9 cuts off the delivery. At the same time, the overflow part of the fluid diffuses into the conical pipe 5 through the vertical pipe 3. Affected by the buoyancy of the fluid, the float 6 floats up to block the connecting pipe 7. At this time, open the solenoid valve 10 to discharge the overflow fluid from the overflow pipe 11, thereby completing the use of the anti-overflow crane pipe for fluid loading.
