TL;DR: In this article, a method for achieving power output through hydraulics and a hydraulic piston is described, which is used for step construction at places with large river elevation differences but also be used at rivers and lakes without large elevation differences; besides, the hydraulic piston can be used through industrial and domestic wastewater.
Abstract: The invention discloses a method for achieving power output through hydraulics and a hydraulic piston. The hydraulic piston comprises a cylinder body, a piston body matched with the cylinder body, and a power output device connected with the piston body. The piston body is composed of an upper gravity cabin and a lower buoyancy cabin. A gap is reserved between the piston body and the inner wall of the cylinder body. The piston body is connected with the inner wall of the cylinder body in a rolling mode through a guide device. The piston body is made to descend through the gravity of water, the piston body is made to ascend through the buoyancy of the piston body, and therefore the piston body reciprocates vertically, in this way, the power output device is driven to output energy. Thus, in the whole power output process, no fuel needs to be consumed, no pollution is caused, and a small amount of water is consumed; the requirement for water level elevation differences is not high, so the hydraulic piston can not only be used for step construction at places with large river elevation differences but also be used at rivers and lakes without large elevation differences; besides, the hydraulic piston can be used through industrial and domestic wastewater.
