Disclosed are a bailer-type long-shaft pump (100) and an associated pump station (200). The long-shaft pump comprises a bailer vehicle (110), a long shaft (120), a bearing (130), a transmission device (140) and an electric motor (150). One end of the long shaft (120) successively passes through the bearing (130) and the transmission device (140) so as to be in transmission connection with a drive shaft of the electric motor (150). The pump station (200) comprises a pump station foundation (210), several equipment rooms (231) transversely distributed at intervals and constructed on the pump station foundation (210), and two ends of the long shaft (120) are supported on side walls of two adjacent equipment rooms. The bailer-type long-shaft pump achieve large water flow and low lift, the pump station is space-saving, has shorter construction cycle, and reduces investment and operation costs.

A turbine has a rotatable outer casing with an inlet and an outlet therein. A casing rotation control causes the casing to rotate about a central point thereof such that the inlet consistently faces an incoming flow of ambient fluid. The casing has two spaced-apart portions in shapes of oppositely-disposed concave arcs (also referred to as “deflector plates” of a same circle. In some embodiments, each concave arc of the casing forms a unitary structure with a respective convex arc, the two spaced-apart convex arcs lying on either side of the outlet. In some embodiments, each concave arc is connected to a respective second concave arc at an endpoint thereof, the second concave arcs being rotatable about the point of connection.

A river, tidal, wave or ocean current or a wind turbine for generating electricity harnesses a predetermined minimum or baseload value of hydrokinetic/wind energy from variable water/wind flow. A harnessing module may have a waterwheel or propeller and a-generator or a waterwheel or propeller alone. A harnessing module harnesses wind or water energy and may be connected to a land module of electrical and mechanical apparatus by an electrical cable. Received variable electrical input from the harnessing module is converted to a-constant electrical frequency by a connected generator feeding a grid, for example, using a Hummingbird speed converter. The received variable electrical load power may be mechanically corrected by feedback to a Kingfisher converter. An output generator to output constant frequency may use a voltage regulator, a variable voltage transformer and a control motor to provide feed forward control.

A river, tidal, wave or ocean current turbine harnesses a predetermined minimum/maximum or baseload value of hydrokinetic energy from variable water flow. A wind turbine for generating electricity may follow similar principles. A harnessing module may consist of a waterwheel and a generator or a waterwheel alone. A harnessing module harnesses wind or water renewable energy and may be preferably connected to a land module of rotational speed control electrical and mechanical apparatus through a flexible electrical cable. Received variable electrical input from harnessing module is converted to a constant electrical frequency by a connected generator feeding a grid, for example, using the Hummingbird speed converter. The received variable electrical load power may be mechanically corrected by feedback to the Kingfisher converter while feedforward control of an output generator to output constant frequency may be provided using a voltage regulator, a variable voltage transformer and a control motor. The electrical input receiving land module may process multiple inputs from any types of harnessing modules including wind and water turbines.
