求翻译：井下整个系统的供电不需用寿命有限的蓄电池供电，而是使用井下无限制的机械能转换为电能的发电机供电，实现井下与地面的实时通信。是什么意思？

Underground power supply system with limited life without using battery power, but the use of underground unlimited mechanical energy into electricity power generators, underground and ground to achieve real-time communication.

Wells under the Electricity Supply System as a whole is not required for the purposes of life is limited battery power supply, but rather use the wells of unlimited mechanical energy into electrical energy to convert the generators, achieving downhole and surface-based real-time communications.

The mine shaft overall system power supply does not have with the life limited accumulator cell power supply, but is uses the mine shaft unlimited mechanical energy to transform into the electrical energy generator power supply, the realization mine shaft and the ground real-time communication.

Underground power supply of the entire system is not required for limited battery life, but instead uses underground unlimited Generator converts the mechanical energy of electricity power supply to achieve real-time communications of downhole and surface.

The power supply of the whole system does not need to supply power with the storage battery of limited life-span in the pit, but use the generator that the mechanical energy unrestrictedly changes into the electric energy to supply power in the pit, realize in the pit with the communicating in real
