Method for achieving power output through hydraulics and hydraulic piston

14 Oct 2015-
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.

TL;DR: In this paper, the authors propose a utility model for a buoyancy water pumping device which is a water elevating mechanical device utilizing the potential energy of water with certain drop height and flow quantity to make a floating body with a proper volume.
Abstract: The utility model relates to a buoyancy water pumping device which is a water elevating mechanical device utilizing the potential energy of water with certain drop height and flow quantity to make a floating body with a proper volume and capable of doing an elevating motion in the buoyancy water pumping device obtain enough buoyancy from the water to work by using the buoyancy as dynamic force so as to continuously elevate the water from a low position to a high position. The utility model comprises a hydraulic work mechanism composed of at least one container (2), a floating body (6), a piston pump (8), an accumulator (12), etc., and an automatic control mechanism composed of a reversing valve (4), a lever mechanism (14) connected with the reversing valve (4), etc. The buoyancy water pumping device has the advantages of high work efficiency, large water discharge pressure and high pumping range, is widely suitable for working under the conditions of various water sources with low drop height and small flow quantity.

TL;DR: In this article, the utility model discloses a whole power take off process need not to consume fuel, and is pollution free to the consumption water yield is little, requires not highly to the water level discrepancy in elevation, not only can use in the step construction of the river discrepancy in the elevation great department, does and uses in river and the lake department that does not possess a great discrepancy in elevations, can also utilize the use of industry and sanitary wastewater.
Abstract: The utility model discloses an utilize hydraulics to realize power take off's hydraulics piston, this hydraulics piston include the cylinder body, the piston body that matches with the cylinder body and the power take -off who is connected with the piston body, the piston body constitute by the gravity cabin of top and the buoyancy compartment of below, and be provided with the clearance between piston body and the cylinder body inner wall, the piston body passes through guider and cylinder body inner wall roll connection. The utility model discloses the gravity that utilizes water makes the piston body descend, recycles water and makes the piston body rise to the buoyancy of piston body, realizes back and forth movement about the piston body to drive the mesh that power take -off reaches energy output. Therefore, the utility model discloses a whole power take off process need not to consume fuel, and is pollution -free to the consumption water yield is little, requires not highly to the water level discrepancy in elevation, not only can use in the step construction of the river discrepancy in elevation great department, does and uses in river and the lake department that does not possess the great discrepancy in elevation, can also utilize the use of industry and sanitary wastewater.

TL;DR: In this article, a floating water tank is arranged in a water well pond provided with a water inlet valve and a water outlet valve, lifting ropes which extend out of the water well ponds are arranged above and below the floating tank, and the switch valves are regulated and controlled through a computer.
Abstract: The utility model provides a potential energy power output device, a floating water tank is arranged in a water well pond provided with a water inlet valve and a water outlet valve, lifting ropes which extend out of the water well pond are arranged above and below the floating water tank, a water inlet and a water outlet are formed on the floating water tank, and the water inlet valve, the water outlet valve, the water inlet and the water outlet are provided with switch valves which are regulated and controlled through a computer. The valves are regulated and controlled through the computer, the floating water tank can fall into water after being filled with water, the water is further drained through the water outlet, the water inlet valve supplies the water into the water well pond for leading the floating water tank to float to the top part and further carrying out water filling, and the circulation is carried out repeatedly in such way, thereby leading the upper and the lower lifting ropes which are connected with the floating water tank to form the reciprocating motion, driving other equipment to operate, achieving the purpose of power output, being capable of being mounted below a dam and other reservoirs, and having the significant characteristic of saving the water by about 80%.
