Problems solved by technology
The introduction of external power from the outside of the tunnel increases the difficulty of tunnel construction, and the maintenance work after completion is also difficult. The battery power supply also needs to be manually replaced regularly. Some tunnel device monitoring equipment usually needs to be buried in the foundation or in the wall. Or it is more inconvenient to replace the battery

The invention discloses an electromagnetic charging device by utilizing tunnel pressure change. The electromagnetic charging device by utilizing the tunnel pressure change comprises an array hole box body, a permanent magnet block, a spring, a barrel-shaped coil winding support, an electric conduction coil, a rectifier, a charger and a charging battery. The electromagnetic charging device by utilizing the tunnel pressure change is based on the principle that a magnetic line of force is cut by a coil to generate electric current, ,and utilizes transient air pressure in a tunnel when a high speed train passes through the tunnel to enable the permanent magnet block to quickly slide back and forth in a barrel shaped coil winding support, so that the electric conduction coil cuts the magnetic line to generate induced electric current to convert air energy to electric energy. Due to the fact that an electric device meter in the tunnel does not need to introduce the power supply outside the tunnel, and the electromagnetic charging device by utilizing the tunnel pressure change directly supplies power, a great deal of cost of capital is saved, and tunnel construction difficulty is reduced.
Description
Technical field [0001] The invention relates to a charging device, in particular to an electromagnetic charging device utilizing tunnel air pressure changes. Background technique [0002] Various instrumentation devices need to be placed in the tunnel to ensure the normal and safe passage of cars or trains through the tunnel, and at the same time carry out tunnel safety monitoring. These instrumentation devices need to be powered to work normally. Currently, they usually need to be powered from outside the tunnel or powered by batteries. The introduction of external power from the outside of the tunnel increases the difficulty of tunnel construction, and the maintenance work after completion is also difficult. The battery power supply also needs to be manually replaced regularly. Some tunnel device monitoring equipment usually needs to be buried in the foundation or in the wall. Or it is more inconvenient to replace the battery. Contents of the invention [0003] The pur...
