The specific working principle of the invention is as follows:
when the hydrogen filling device is used, the shell 100 is in an initial state, the influence of the external temperature on the filling of the internal hydrogen can be effectively avoided by adopting a double-layer vacuum heat insulation structure, the connection stability of the connection piece 301 connected with the hydrogen generator and the hydrogen filling equipment can be ensured through the inner guide groove 3012, when the hydrogen filling is not carried out, the opening and closing disc 3021 of the opening and closing piece 302 is attached to the fixed sealing ring 3024 under the action of the spring 3022, the external pollution to the communication pipe 400 can be avoided, the residual hydrogen in the communication pipe 400 can be prevented from leaking, then the hydrogen generator and the hydrogen filling equipment connecting pipe are inserted into the connection piece 301, when the hydrogen filling is carried out, the power switch is started, the annular electromagnet 3025 is matched with the permanent magnet 3026, the movable sealing ring 3023 is separated from the fixed sealing ring 3024, the hydrogen passing through the connection piece 301 enters the communication pipe 400 through the opened opening and is filled, the leakage situation does not occur in the process, and the safety is improved.
When a small amount of hydrogen leaks from the shell 100 in the use process, the hydrogen leaks to react with an adsorbent layer on the hydrogen adsorption component 200, when the hydrogen adsorption component 200 needs to be replaced, the replacement is convenient to detach, the detachment is convenient, a sealing element is arranged between the shell 100 and the hydrogen adsorption component 200, and the arrangement of the sealing element ensures that the hydrogen leakage occurs when the hydrogen injection process is not influenced after the hydrogen adsorption component 200 is installed, so that the hydrogen leaks to the shell 100, and serious consequences are caused;
when hydrogen leaks too much, the hydrogen detection sensor senses and transmits a signal to the microprocessor, the microprocessor processes the hydrogen through the fire control monitoring component, the hydrogen detection sensor collects and is arranged on the shell 100 to detect a hydrogen concentration value, the detected hydrogen concentration value is sent to the microprocessor, whether the hydrogen is leaked or not is judged according to the hydrogen concentration value, if the hydrogen is leaked, the microprocessor controls the annular electromagnet to control the opening and closing member 302 to be closed, the emergency stop unit starts emergency gas stop, and the hydrogen is stopped from being injected; the ring-shaped electromagnet is controlled to close the opening and closing piece 302, and an alarm is given through the alarm unit to inform a worker to process.
