The invention discloses a power generation seat based on a hydraulic transmission principle. The power generation seat comprises a seat base. A plurality of annular pipelines are arranged on the seat base. A plurality of thrust piston bodies are arranged in each annular pipeline. An airtight cavity is formed by the seat base and each thrust piston body. The airtight cavities are filled with liquid. Each thrust piston body comprises a seat face module, a drive piston rod and a cylinder, wherein the cylinder is sleeved with the corresponding annular pipeline, and the seat face module is connected with the cylinder through the drive piston rod. The part, below the thrust piston bodies, of each annular pipeline is internally provided with a plurality of impellers which are connected with a power generator. The liquid flows in the annular pipelines under the push of the thrust piston bodies, the impellers are impacted to rotate, and the power generator is driven to generate power. The power generation seat is simple in structure, low in manufacturing cost, capable of providing a solution idea for increasingly-strained energy supply and environment pollution, and capable of providing an environment-friendly and pollution-free energy collection technology.
