[0002] The pressure of the natural gas pipeline network is much higher than the pressure required by users, and it contains huge pressure energy. Using pressure energy to generate electricity on site is a feasible solution. Traditional pressure energy utilization devices occupy too much space and require staff to operate, and the cost is too high, so they cannot be widely used.

[0025] In the gas pipeline built-in power generation device based on Roots power generation of the present embodiment, when the telescopic slide 8 moves to the end of the telescopic slide 6, the internal connecting pipe 10 is opposite to the inner end of the external connecting pipe 4. At this time, the gas pipeline is connected to the internal connecting pipe 10 through the external connecting pipe 4, and then connected to the Roots power generation assembly 9.

[0032] Similarly, when the direct-connected pipe 19 is opposite to the inner end of the external connection pipe 4, the horizontal electric push rod 14 drives the horizontal slide seat 13 to move in the horizontal slide groove 12, so that the sealing sleeve 16 is sleeved on the direct-connected pipe 19, and then the rotating motor 18 drives the sealing sleeve 16 to rotate, so that the two ends of the sealing sleeve 16 are respectively sealed and connected to the direct-connected pipe 19 and the external connection pipe 4, so that the direct-connected pipe 19 is connected to the gas pipeline.
