Title:

PRIME MOVER AND WORK-DOING METHOD AND A WATER TURBINE GROUP

Document Type and Number:

WIPO Patent Application WO/2021/104540

Kind Code:

A1

Abstract:

A prime mover, a work-doing method of the prime mover, and a water turbine group, comprising an evaporator (2), an engine body (3), and an energy body (4). The energy body (4) is slidingly arranged inside the engine body (3), and a sealed cavity (6) is formed in between the bottom of the energy body (4) and the inner walls of the engine body (3), or an expandable inner container (19) is arranged between same. The evaporator (2) is in communication with the cavity (6) or the inner container (19), and the evaporator (2) continuously absorbs heat to evaporate a liquid-state working medium to drive a stroke of the energy body (4) to moving upwards and doing work up to an upper limit. When the ambient temperature meets a liquefaction temperature, the energy body (4) moves downwards under its own weight and compresses the gas-state working medium to complete liquefaction. The entire work-doing process and the liquefaction process do not require additional auxiliary devices, avoiding unnecessary energy consumption. The invention features a simple overall structure, low costs, stable performance, and high efficiency.
