摘要： The present invention relates to a movable and semi-submerged power generator using a waterwheel turbine, which can easily be moved to a location where a flow of a fluid occurs, prevents movement by current of water due to being a semi-submerged type, and efficiently produces energy by means of a flow rate control and cutoff of the fluid and expansibility of the turbine. The power generator comprises: an upper structure having first and second structures including first and second balancing tanks and first and second machine rooms; a lower structure disposed on the lower portion of the upper structure and including a fluid flowing hole, a first round, and a fluid guide hole through which the fluid can flow; a turbine rotated by the movement of the fluid; an energy generation means for producing electricity by the turbine; and a fixing means. Thus, the power generator is floatable and movable on water so as to be moved to and installed in various locations. The first and second balancing tanks are filled with the fluid such that the power generator can be semi-submerged, and the height of the turbine is disposed at a position so that a shaft can be placed above the water surface such that the turbine is smoothly rotated, while preventing shaking by waving of the fluid and turning of the power generator, thereby improving energy production efficiency. Also, the fluid under the water surface is guided in a direction capable of operating the turbine while maximally preventing disruption to the flow of the fluid moving to the turbine through the first round of the lower structure, thereby improving energy production efficiency.

摘要： A wind powered turbine has a conduit. A middle conduit portion is located between inlet and outlet conduit portions, having a main inlet and outlet of the conduit, respectively. A rotor having a shaft with blades extending therefrom is located in the middle conduit portion. The blades are located completely within the middle conduit portion. Preferably, a splitter is located in the inlet conduit portion to provide upper and lower sub-tunnels that both feed into the middle conduit portion. Upper and lower interior walls of the middle conduit portion have substantially circular plane shapes that are substantially centered at the rotational axis of the shaft. Upper and lower clearance gaps are located between the blades and the upper and lower interior walls, respectively. The main outlet is preferably higher than the main inlet. Preferably, a generator is located on each side of the conduit and rotatably coupled to the shaft.

摘要： A mud by-pass regulator apparatus for regulating the flow of drilling fluid through the turbine of a downhole power generator supply in a measurement while drilling system includes a valve (94), valve actuator (50), and a valve actuator control (60, 64, 72). Pressure differential across the turbine is sensed by a piston (60) located between high pressure (72) and low pressure (64) chambers increase in pressure differential moves valve actuator (50) against the bias of a spring (58) to move valve (94) away from turbine (88) and allow more fluid to by-pass the turbine. This ensures regulation of the drilling fluid flowing through the power supply so that its operation is maintained within required limits of the downhole portion of the measurement while drilling apparatus.
