A water current catcher system for hydroelectricity generation includes a first L-shaped weir, a second L-shaped weir, a channel opening, an underwater gate assembly, and at least one elevation adjustable hydroelectric generator unit. The first and second L-shaped weir are connected to a subsurface environment and linearly positioned to each other. The channel opening is delineated between the first L-shaped weir and the second L-shaped weir. The underwater gate assembly is integrated into the first L-shaped weir, the second L-shaped weir, and the subsurface environment thus positioning about the channel opening. The elevation adjustable hydroelectric generator unit that includes a first jack-up barge, a second jack-up barge, a waterwheel, and a generator is connected to the subsurface environment and adjacently positioned about the channel opening. The elevation adjustable hydroelectric generator unit is operatively coupled with the underwater gate assembly to convert the kinetic energy of flowing water into hydroelectricity.

The present invention related to the ocean wave energy exploiting and storing device for electricity generation.

A tidal current generator relates to a tidal current generator that can efficiently generate power by separating an on-water power generation unit and an in-water power collection unit, that allows for easy management of facilities on the water because the facilities in the water can be easily pulled up on the water even if they break, that can maximally use the flow of tides using a connection rope and a groove formed on a rotary propeller, and that can maximize efficiency by controlling the number of power connections between a rotary unit and an on-water power generator in accordance with the states of the flow of tides to prevent waste or deficit of power transmission.

An adjustable platform for installing a wind turbine generator comprises an adjustable platform shell, the adjustable platform shell is installed on a hull, pile legs are connected vertically in the adjustable platform shell in a sliding way, a plurality of adjusting jacks are arranged on the pile legs, an electric plug-in component is arranged in the adjustable platform shell and used for fitting with the adjusting jacks. The fitting of electric plug-in component with the adjusting jacks of the pile legs replaces the bolted connection between the installation platform and the pile legs, and the electric power is used to replace the manual operation, solving the technical problems in the prior art that bolted connection is required between the installation platform and the pile legs, bolts are required to be removed manually before the pile legs sink, and the labor cost is greatly consumed.

The invention relates to a tower section and to a method for raising said section with a complete new or existing wind turbine on the upper part thereof, the assembly being raised to heights greater than 120 meters by means of a raising system that operates at ground level and gradually inserts modular frame structures through the lower part. The modules have heights between 10 and 14 meters and are formed by a trellis of at least three vertical columns and with diagonal elements which react to the twisting moments and shear forces generated by the action of the wind. A transition part with a base sufficient for raising in wind conditions greater than 15 meters/second is disposed on top of the modules. The raising method has several steps, for example: producing and installing a foundation; assembling the transition part on a connection element of a footing; mounting the wind turbine complete with the tubular tower, nacelle and rotor thereof; installing a lifting system and joining structures on a connection element of the footing; lifting a module N; assembling the different modules; and lastly assembling the final module and removing the automatic raising system.
