The safety of the hydrogen energy emergency power generation vehicle mainly refers to the safety of a vehicle-mounted hydrogen system, and the vehicle-mounted hydrogen system comprises a hydrogen storage system, a hydrogen fuel cell power generation system and the like. In order to provide safe electricity-protecting service, the invention carries out explosion-proof and anti-static design on the aspects of the compartment structure, the used materials and the like of the hydrogen energy emergency power generation vehicle. The specific implementation mode is as follows:

a hydrogen energy emergency power generation vehicle is shown in figures 1 to 3 and comprises a carriage 1, wherein a hydrogen fuel cell power generation system installation area, other equipment installation areas, an operation channel and a hydrogen storage system installation area are divided in the carriage 1, and the hydrogen fuel cell power generation system installation area is separated by an independent shell 11 to form an independent hydrogen leakage accumulation space 4 which is completely isolated from the other equipment installation areas and the operation channel; the hydrogen storage system installation area divides the inside of the vehicle compartment 1 into the separate hydrogen leakage discharge space 5 by a horizontally arranged partition plate 12, and the hydrogen leakage discharge space 5 is located above the hydrogen leakage accumulation space 4, other equipment installation areas, and operation passages.

A hydrogen fuel cell power generation system of a vehicle-mounted hydrogen system is installed in the hydrogen leakage accumulation space 4, and a hydrogen storage system is installed in the hydrogen leakage discharge space 5.

The top end of the independent shell 11 is abutted against the partition plate 12, the top end of the independent shell and the partition plate are provided with a plurality of vent holes 13 in a penetrating way, and the vent holes 13 form a vent area so that the hydrogen leakage accumulation space 4 is communicated with the hydrogen leakage discharge space 5; the compartment 1 is also provided with a ventilation structure 6 for communicating the hydrogen leakage discharge space 5 with the external environment, and the ventilation structure 6 is selected as a louver in the embodiment.

Thus, if hydrogen leaks from the hydrogen fuel cell power generation system, the hydrogen floats up in the hydrogen leakage accumulation space 4, enters the hydrogen leakage discharge space 5 through the vent hole 13, is discharged out of the vehicle compartment 1 from the shutter, and cannot be retained in the independent hydrogen leakage accumulation space 4; if the hydrogen storage system leaks, hydrogen is discharged to the atmosphere through the shutter and does not accumulate in the hydrogen storage space, thereby reducing the possibility of danger.

Furthermore, the top of the independent shell 11 is obliquely arranged towards the vent hole 13, and when hydrogen floats upwards in the hydrogen leakage accumulation space 4, the hydrogen can be converged to the vent hole 13 along the inclined surface at the top of the independent shell 11, so that the hydrogen accumulation speed is accelerated, and the hydrogen discharge time is shortened; correspondingly, the inner top surface of the hydrogen leakage discharging space 5 is provided with a guiding structure 51 for guiding the hydrogen to the ventilating structure 6; in this embodiment, the ventilation structures 6 are disposed on two sides of the carriage 1, the guiding structure 51 is an arc structure with a low middle and two high sides, and hydrogen can be gathered towards two sides of the carriage 1 along the arc curved surface and is rapidly discharged to the atmosphere through the ventilation structures 6 on two sides of the carriage 1, so that hydrogen accumulation is avoided.

Here, the safety of the system is guaranteed in terms of pressure relief of the hydrogen storage system.

The explosion-proof design of the hydrogen energy emergency power generation vehicle is mainly embodied from the selection of explosion-proof accessories, for example, an explosion-proof lamp is selected as an illumination system of the emergency power generation vehicle, and an explosion-proof device is used as a travel switch of a carriage door 15.

The anti-static design of the hydrogen energy emergency power generation vehicle comprises the steps that an anti-static dragging zone is arranged at the bottom of the tail of the emergency power generation vehicle, so that a carriage 1 is connected with the ground; the carriage door 15 and the equipment door are both connected with the shell by adopting ground wires; the floor mat of the internal passage of the carriage 1 is made of antistatic silica gel material; the tail of the carriage 1 is provided with an anti-static metal ball which can remove static electricity carried by a human body before going.
