The invention relates to the technical field of hydrogen energy power generation, in particular to afire extinguishing system of a hydrogen power generation vehicle. The system is characterized by comprising a linkage shutter arranged at the top of a compartment and a first hydrogen concentration sensor arranged at the position close to the top wall of the compartment, a signal processor is coupled to the first hydrogen concentration sensor; a set value is preset for the first hydrogen concentration sensor in the signal processor, when the first hydrogen concentration sensor detects that the hydrogen concentration in the compartment is greater than the set value, the linkage shutter is opened, and when the first hydrogen concentration sensor detects that the hydrogen concentration in the compartment is lower than the set value, the linkage shutter is closed. The purposes of reducing the hydrogen concentration in the working environment and reducing potential safety hazards are achieved.
Description
technical field [0001] The present application relates to the technical field of hydrogen energy power generation, and in particular, to a fire protection system for a hydrogen power generation vehicle. Background technique [0002] Hydrogen power generation refers to the use of hydrogen and oxygen to burn to form a hydrogen-oxygen generator set. Hydrogen generator refers to a generator that uses hydrogen as raw material. It uses the principle of internal combustion engine to drive the motor to generate electricity through processes such as inhalation, compression, explosion, and exhaust. current output. [0003] In the related art, a hydrogen power generation vehicle is a new energy power generation facility that uses hydrogen as a fuel. A series of supporting devices such as a control system, a high-pressure hydrogen storage tank, and a hydrogen fuel cell power generation system need to be installed in the interior of the hydrogen power generation vehicle. [0004] In vie...
