A water driven power generating system has a frame with a waterwheel carried within the frame in an upright manner having a plurality of water receiving elements for turning the waterwheel. A water discharge manifold is used to discharge water from a supply tank onto the water receiving elements. The water supply tank is supplied with water from an adjacent water reservoir, such as a stock tank. After passing over the water receiving elements of the water wheel, the discharge water is allowed to flow back to the water reservoir by gravity. The water used in the system is pumped from the reservoir to the supply tank by a truck mounted pump which is powered by the power take-off of the truck.

Through dividing all blades into four or more blade groups including a certain number, which is three or more, of the blades, the blade located in the rearmost portion of each blade group in a direction of rotation is selected as a main blade, and remaining blades are selected as auxiliary blades, the length of each of the auxiliary blades is set to be shorter than the length of the main blade, and corresponding inner edge portions are positioned to the front, in the direction of rotation, of a normal line that passes through an outer edge portion of the blade, and an extension line of a chord line that connects the outer edge portion and the inner edge portion of the blade to one another are made to intersect with the main blade that is adjacent to the front in the direction of rotation.

An air turbine starter device comprises a rotor arranged in a cavity of a housing, a first manifold having a cavity with a port operative to direct compressed air to the rotor, a second manifold having a cavity with a port operative to direct compressed air to the rotor, wherein the first manifold is larger than the second manifold.

A hydropower recycle system, relating to the technical field of hydroelectric power generation, includes a turbine device, a power generating device and a rooftop water tank. A water inlet is provided at the top of the rooftop water tank. The turbine device includes a turbine housing provided above the water inlet with a water outlet being provided at the bottom of the turbine housing. A turbine is provided inside the turbine housing with a turbine rotating shaft passing through the turbine housing. One end of the turbine rotating shaft is transmittingly connected to an input shaft of the power generating device. A high-pressure nozzle is fixedly disposed on a sidewall of the turbine housing. The hydropower recycle system has the advantages of small commitment resources, short installation and debugging time, and slight influence on the environment.

A hydraulic turbine motor has a rotor housing and a rotor rotatably supported in the rotor housing that defines a plurality of rotor chambers arranged circumferentially about the rotor in which each rotor chamber has a respective outlet port. Injectors are supported at circumferentially spaced locations about the housing so as to be arranged to inject hydraulic fluid in a generally tangential direction relative to the rotor axis into selected ones of the rotor chambers in which the injectors include first and second injectors. A valve mechanism is configured to open any outlet port in which the respective rotor chamber is in communication with one of the first injectors and to maintain closed any outlet port in which the respective rotor chamber is in communication with one of the second injectors.

An embodiment of a system includes a pipeline of a wastewater system, an equalization tank that is configured to receive wastewater from the pipeline, and a return line extending from the equalization tank to the pipeline. In addition, the system includes an electricity generation assembly in fluid communication with the return line that is configured to generate electrical power using a flow of wastewater through the return line. The electricity generation assembly includes a flow channel, a water wheel that is partially inserted into the flow channel such that a portion of the water wheel is extended outside of the flow channel, and an electrical generator connected to the water wheel.

A recirculating hydro-pneumatic impulse turbine including a collector assembly including a central draft tube extending therebelow, the collector assembly including a collector plate having a generally horizontal upper surface and being configured such that the draft tube is in fluid communication with the upper surface, there also being a series of peripherally arranged drive cups about the upper surface. The turbine also includes a drive assembly about the central draft tube, the drive assembly including a fluid inlet at its lower end in fluid communication with the lower end of the draft tube, and a plurality of tangentially arranged outlet nozzles configured at its upper end. The turbine also includes a central air tube with an upper air inlet and a lower air distribution manifold, the manifold including at least one venturi outlet capable of entraining air in the fluid to assist movement of the fluid from the lower end of the drive assembly upwardly to the outlet nozzles. During use, fluid jets that form at the outlet nozzles engage with the drive cups to generate relative rotation between the outlet nozzles and the drive cups about a vertical axis, the relative rotation capable of providing useful work, with fluid subsequently flowing from the drive cups across the upper surface of the collector plate to the draft tube, down the draft tube where the fluid enters the fluid inlet of the drive assembly for entrainment with air and recirculation to the outlet nozzles.
