Liquid hydrogen pump with safety protection mechanism for hydrogen refueling station

The invention relates to the field of liquid hydrogen energy, in particular to a liquid hydrogen pump with a safety protection mechanism for a hydrogen refueling station. The technical problem is that an existing liquid hydrogen pump cannot sensitively detect liquid hydrogen leakage at a pipeline joint and safely process leaked hydrogen. According to the technical scheme, the liquid hydrogen pump with the safety protection mechanism for the hydrogen refueling station comprises a shell, a pump machine, a liquid inlet pipe, a liquid conveying pipe and the like; a pump machine is mounted in the shell; the left side of the pump is fixedly connected with a liquid inlet pipe; the right side of the pump is fixedly connected with a liquid feeding pipe. The effect of temporarily storing hydrogen is achieved through the arc-shaped elastic skin, the situation that hydrogen drifts out of the arc-shaped elastic skin, so that hydrogen and air are mixed to generate potential safety hazards is avoided, after hydrogen enters
