A rope-controlled hydraulic cylinder wave power generator comprises a wave energy absorption and conversion part, a rope control device (79), and a gravity anchor (17). The wave energy absorption and conversion part comprises a floating body (1) and a hydraulic system. A hydraulic oil circulating path of the hydraulic system comprises a single-action hydraulic cylinder (2), an exit-allowed one-way valve, a high-pressure energy accumulator, a hydraulic motor, a low-pressure energy accumulator/opening-type oil tank (72), an oil filter, and an entry-allowed one-way valve. A cylinder body of the single-action hydraulic cylinder (2) is connected to the floating body (1). The bottom end of a piston rod (3) of the single-action hydraulic cylinder (2) is connected, through a rope or a lock chain (24), to the top end of a rack (13) of an execution mechanism of the rope control device (79) under the floating body (1). The rope (21) controlled by the rope control device (79) extends downwards to be connected to the gravity anchor (17). The rope-controlled hydraulic cylinder wave power generator is suitable for the situation of large waves, and a rope retraction effect is good.

There is provided a first wave energy converter, operating as a long attenuator, for extracting energy from sea waves comprising a floating flexible power hose, suction coupled to the wave surface. The power hose is buckled by an internal tensioned spinal cord into a resonant waveform that couples with the wave surface to extract energy from the incident waves. The spinal cord drives a skeleton reinforced diaphragm that pumps atmospheric air along the hose at the propagation velocity of waves. The air flow is unidirectional and the air pressure increases at every change of curvature along the flexible hose to produce compressed air. This compressed air is delivered by pipe to land where it can be converted to electricity or used as energy storage. There is provided a second wave energy converter, operating as a long attenuator, for extracting energy from sea waves comprising a floating flexible hose, suction coupled to the wave surface, that transfers energy to an internal buckled elastic spine, tuned to the wave frequency, which drives skeleton reinforced diaphragm seals that pump atmospheric air at the propagation velocity of waves. The air flow is unidirectional and the air pressure increases along the flexible hose to produce compressed air for delivery by pipe to land where it can be converted to electricity or used as energy storage.

||PCT/MX2016/000083||CARRION CUELLAR, Francisco Javier||CARRION CUELLAR, Francisco Javier|
The present invention describes the configuration of a system for generating electricity by means of a rotary rod or rod with an endless thread, so that when a buoy or floating element moves, the rotary rod actuates, optionally by means of an actuator, an alternator or electricity generator having permanent or asynchronous magnets. The buoys are designed according to each site in which they are installed, and comprise an electronic or other type of system that detects the frequency and size of the waves in advance in order to synchronise the frequency of the waves and/or the force thereof with the the energy capture of the buoys. Systems are added so that the generators rotate in a single direction independently of the direction of the buoy, as well as filters and electronic systems that correct the variations in the energy generated to make the frequency suitable for connection to the network, directly to consumers or to batteries or energy storage systems. A system for protecting the equipment against hurricanes or natural phenomena is also installed.

||15777409||WUHAN KAIDI ENG TECH RES INST CO LTD||CHEN YILONG|
An optimized integrated system for solar-biomass hybrid electricity generation. A heat transfer oil outputted from a solar farm (1 and 2) of a solar thermal boiler system flows sequentially through a solar thermal evaporator (6) and a solar thermal heater (5) then back to a heat transfer oil storage tank (4) and is then delivered via a circulation oil pump (3) to the solar farm to complete a heat transfer oil circulation. Solar thermal steam produced by the solar thermal evaporator is delivered to a biomass boiler system (9) via a steam header (7). Auxiliary steam produced by a coal-fired or gas-fired or oil-fired auxiliary boiler (8) also is mixed with the solar thermal steam and delivered to the biomass boiler system via the steam header. The solar thermal mixed steam and steam produced by a biomass boiler itself are delivered to a turbo generator (10) to drive an electric generator (11) into generating electricity. The system simplifies solar thermal power generation system and equipment configurations, provides stable electricity generation, high thermal efficiency, and extended service life.
