In one aspect, a system for generating electricity based on water flow is disclosed. The system comprises a first pipe fitting, a turbine, and a second pipe fitting. The first pipe fitting couples to a pipe that supplies a fluid to a building. The turbine is in fluid communication with the first pipe fitting and rotates in response to a kinetic energy of the fluid supplied by the pipe flowing through the turbine, generates electricity in response to rotation of the turbine, and reduces a pressure of the fluid from a first pressure to a second pressure. The second pipe fitting couples the turbine to an input pipe of the building. The turbine further comprises a conversion circuit that conditions the generated electricity for consumption by the building and conveys the generated electricity to the building via one or more conductors.

An electric power generation system of the present invention comprises an upper reservoir for storing water, a lower reservoir for storing water dropped from the upper reservoir, a pressure chamber for pressurizing and spouting water falling from the upper reservoir, an electric generator formed to be driven by a water turbine rotating by the spouted water and a capacitor, a preliminary power generation equipment that generates electricity using water bypassed from the upper reservoir and water supplied from the outside to charge the capacitor, and a pump that is driven by the capacitor and is formed to pump water from the lower reservoir to the upper reservoir, said electric generator includes an internal power electric generator that supplies the generated power to devices inside the system, and an external power electric generator that supplies the generated power to the outside of the system.

An adapter element for a solenoid valve assembly in an irrigation system includes an integral water turbine generator including an impeller positioned in an outlet flow path of a solenoid assembly thereof such that the impeller rotates when water flows to generate electricity.

A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.

The invention relates in part to an autonomous, self-powered valve for continuous monitoring of water flow within a domestic or commercial water pipe network. The invention also relates to a network in which the valve is remotely monitored for detection of abnormalities in water use patterns.

A combined pump and turbine (electromechanical converter), which may be operable as a motorized centrifugal pump for starting a siphon and as an electromechanical turbine particularly for transmission of a liquid, such as water, in a water treatment plant.

A system and method to direct a communication from a user device to rotate a deflector guide located proximal to a sprinkler head. The sprinkler head rests on a sealed bottom ring comprised of a waterwheel, transformer, rotating slider, and D2M communications device. When water is deployed from the sprinkler head, the waterwheel inside the sealed bottom ring rotates to generate energy. This starts the communication device which maintains a D2M communication signal until the water is turned off. The communication device is managed by a user on a user device through a user interface. After communication signal is selected in the user interface of the user device, the deflector head responds to commands and pivots along a circular path. The deflector comprises an opening that limits the spray from the sprinkler head to a more limited range than if the deflector was not used.

An electrical energy generating device (1) to transform kinetic energy of fluid passing through a pipe into electrical energy, the device may include a flow management unit (2) having a first housing (20) enclosing a plurality of tubes and a first gasket (27); a generating unit (3) having a second housing (30) with a plurality of coils (37) embedded within the second housing (30), a rotor rotatable within the second housing (30); and a connector (4) connecting the flow management unit (2) to the generating unit (3).

A flush valve has a valve body having a flushing tube, a power generating set, and a solenoid valve assembly. The power generating set is disposed within the flushing tube and has a turbine capable of rotating, an induction coil, and a magnet inserted through the induction coil and capable of simultaneously rotating with the water turbine. The solenoid valve assembly has an assembling mount, a solenoid valve assembled to the assembling mount, and a power supply electrically connected to both the induction coil and the solenoid valve. A first reserving space is formed between the assembling mount and a relief assembly. A second reserving space is formed between the solenoid valve and the assembling mount and communicates with the first reserving space. The solenoid valve optionally prevents the first reserving space and the second reserving space from communicating with each other.
