摘要:
Disclosed herein are linear hydraulic turbines in which the linear machine converts the majority of available energy in the flowing water into useful torque directly in the runner, leaving the outflow with very little velocity.

The invention relates to hydroelectric power industry and can be used for capturing the energy stored within atmospheric moisture at any location worldwide. The objective of the invention is to expand functional capabilities and increase specific power of a hydroelectric power plant by using a maximum possible level difference between the head race and tail race (from the atmospheric moisture condensation level to ground level). The main additional functional capability of such an aero-hydroelectric power plant consists in that it can operate practically anywhere, whilst taking up a very small amount of space on the ground, and can even be mobile. Moreover, it makes it possible to produce, at any location, clean water for drinking and irrigation, without causing any damage to the environment as a result of comparatively small hydro flows. The device comprises a tail race (1), a head race (2), a water conduit (3), a turbogenerator (4), meshed, woven or filmed surfaces (5), an airship (6), and fastening cables (7). The airship (6) raises the surfaces (5) to the altitude above the dew point corresponding to the given atmospheric conditions (usually, 2-3 km). There, the supercooled atmospheric moisture starts to condense (accumulate) actively on the surfaces (5). A drainage system provided on the surfaces (5) takes this water to a small reservoir (head race 2), from which the water, under a head caused by the entire altitude level difference, passes along the water conduit (3) into the tail race (1) on the ground, thereby producing electrical power in the turbogenerator (4).

The invention relates to a free jet turbine – having a blade wheel; - having a plurality of cups distributed over the circumference of the blade wheel; - each cup comprising two shells axially adjacent to each other, separated by a jet divider, and having working surfaces impacted by the water jet; - having at least one nozzle for applying a water jet to the cups. The invention is characterized by the following features: - the working surface are wholly or partially formed from an operative body; - the operative body is supported by a supporting body fixed to the blade wheel; - the operative body can be removed from the supporting body and fixed thereto again.

Ein Turbinenlaufrad (1), beispielsweise ein Peltonlaufrad, besteht aus mehreren, stoffschlüssig miteinander verbundenen Scheiben (4, 4', 4). Auf diese Weise können Turbinenlaufräder (1) einfacher, schneller und günstiger hergestellt werden.
摘要:
Pelton buckets generally have flat outlet edges and are only downwardly sloped in the area of the bowl base under certain circumstances. This flat shape naturally limits the optimization possibilities in order to optimize the deflection of the jet in the Pelton bucket with regard to the efficiency of the Pelton turbine. The invention thus relates to a special shape of a Pelton bucket that is accompanied by a substantial gain in efficiency.

An impulse turbine comprises at least one runner (10; 110; 210) provided with a plurality of blades (14; 14a; 114; 214) and adapted to rotate about an axis of rotation (A) as a result of the delivery of a pressurized fluid to the blades (14; 14a; 114; 214) through fluid delivery means which include at least a nozzle (20; 120; 220) facing an active surface (22; 22a, 22b; 122; 222) of the blades. Each nozzle (20; 120; 220) includes an outflow portion (20a; 120; 220a) lying substantially in a general plane of the runner (10; 110; 210) and extending in an inner zone of the runner between the blades (14; 14a; 114; 214) and the axis of rotation (A). The outflow portion (20a; 120; 220a) of the nozzles (20; 120; 220) is directed towards the outside of the runner (10; 110; 210) along a direction parallel to and spaced from the radial direction of the runner, and each blade (14; 14a; 114; 214) of the runner (10; 110; 210) define an arched path extending transversely to the plane of the runner (10; 110; 210).
摘要:
A plant, generator and rotating member for the production of power from currents in a body of water, comprising a fixedly mounted or floating structure, and a plurality of replaceable generator units (750) supported by the structure and which are driven by the water currents. The structure comprises arms (615, 720, 730). The rotating member (400) comprises a plurality of member sections (410) rotatably mounted on a shaft (405) between an end piece (407) and a tip (406). The generator comprises a contra-rotating rotor (550) and stator (800) connected to respective shafts (500, 820) and bearings, where the stator frame (800) is axially supported (810) on the first shaft (500) and the first shaft (500) at one end thereof is axially supported (810) on the stator frame. The generator according to the invention can be used for the production of electric power, and as an electromotor for the production of mechanical rotational energy.
