The power generation device with the built-in pipeline is adopted for the pressure regulating station and the pressure regulating box with small space, the requirements can be met under the condition of low cost, and the power generation device can be flexibly transported and installed in various places with existing gas pipe networks. However, the existing natural gas pipe network built-in pressure energy power generation device can only be used for a low-pressure pipe network, and the reason is not that mechanical equipment is not high-pressure resistant, but a power output binding post is generally only within 1MPa of pressure resistance. Other power generation methods such as magnetic power generation and the like are easy to demagnetize due to low magnet efficiency, and cannot efficiently utilize pressure energy to generate power due to the fact that the wall thickness of a high-pressure pipeline exceeds the effective magnetic induction distance.
