The invention discloses a low-temperature heat source liquid working medium energy storage thermal expansion and cold shrinkage driving hydraulic piston engine power generation system. A high-pressure tank communicates with a cylinder body through a liquid guide pipe, a piston is arranged in the cylinder body and slidably connected in the cylinder body, the end, away from the liquid guide pipe, of the piston is connected with one end of a telescopic connecting rod, the other end of the telescopic connecting rod is in transmission connection with a power input shaft of a generator through a crankshaft, and the high-pressure tank circularly moves between a hot working medium pool and a cold working medium pool. The system has the technical effects that the high-pressure tank communicates with the cylinder body through the liquid guide pipe, the piston is arranged in the cylinder body and slidably connected in the cylinder body, the end, away from the liquid guide pipe, of the piston is connected with one end of the telescopic connecting rod, the other end of the telescopic connecting rod is in transmission connection with the power input shaft of the generator through the crankshaft, and the high-pressure tank circularly moves between the hot working medium pool and the cold working medium pool.
Description
technical field [0001] The invention relates to the technical field of power generation systems, in particular to a low-temperature heat source liquid working medium energy storage thermal expansion and cold contraction driving hydraulic piston engine power generation system. Background technique [0002] At present, the technologies that use heat sources to generate electricity generally use high-temperature heat sources to generate electricity, such as solar molten salt photothermal power generation, which uses multi-faceted mirrors to concentrate sunlight to heat molten salt, and then uses high-temperature molten salt to generate high-pressure steam to drive steam turbines, and steam turbines drive generators; Hot dry rock power generation uses geothermal heat deep underground to produce high-pressure steam to generate electricity; while solar Stirling power generation uses concentrating mirrors to condense sunlight to heat a Stirling engine to drive a generator to generat...
