摘要： The present invention features a flood damage prevention apparatus having a modular equilateral triangular prism enclosure with an interlocking system used to interlock and position additional modules of the apparatus during flood damage prevention deployment. The interlock system enables additional modules of the flood damage prevention apparatus to be locked in position. Each module may be protected from flood debris damage by way of a protective covering over each enclosure. The apparatus may be filled with fluid via a seal tight opening located on the surface of the enclosure which in turn may be closed using a seal tight apparatus.

摘要： In a hydroelectric generation apparatus placed in a water body, a dam unit divides the water body into a high-water level region and a low-water level region. A drive unit includes a shaft and a vane unit. The shaft extends transversely of a flow direction of the water flow of the water body. The vane unit extends helically around the shaft. The vane unit has a lower vane portion beneath the shaft. The lower vane portion is propelled by the water flow to rotate the shat. A power generation unit is driven by the drive unit to generate power.

摘要： A submersible turbine generator unit can be placed in rivers, streams, or anywhere water flows in order to generate electricity without the need for dams. It is designed to work with its own diversion equipment for controlling and directing a flow of water into the turbine blades. The unit can be raised and lowered in the flow to enhance efficiency, respond to changing flow conditions, and for inspection/servicing, etc. The positioning system can use a motorized worm gear and a rack to raise or lower the turbine generator combination. Once raised up, a hard connection point allows attachment of a lifting cable so the turbine/generator combination can be easily removed and replaced as needed. A submersible turbine generator utilizes uniquely shaped turbine blades that efficiently engage flowing water and spin the turbine shaft without presenting undue risk to aquatic life.

摘要： A hydro-electric power system includes two containers and a support beam having two ends, each end holding one of the containers. The ends allow the containers to travel along a length of the support beam. The support beam pivots about a pivot point, giving each container a maximum height and a minimum height. Fluid flows into each of the containers when located near their maximum height, the flow of water weighting each container and causing it to descend, each container moving longitudinally outward from the pivot point along the support beam as it descends. A dumping mechanism causes each container to release fluid near its minimum height, each container ascending after releasing water and moving longitudinally inward toward the pivot point along the support beam.

摘要： The present invention relates to a hydraulic energy store (1) having a first (2) and a second fluid reservoir (6), the fluid levels (4, 12) of which extend at different heights, which are connected to one another via a turbine/pump arrangement (10) and during the operation of which a fluid (3) can be moved to and fro between the first (2) and second fluid reservoir (6) and energy can be converted in the process. The second fluid reservoir (6) is configured as a container which is arranged within the fluid (3) in the first fluid reservoir (2), wherein, during operation, the fluid level (12) in the second fluid reservoir (6) can be changed in such a way that, as a result, the immersion depth (ht) of said second fluid reservoir (6) in the first fluid reservoir (2) can be changed owing to buoyancy.
