Description
Technical field
The utility model relates to and utilizes the ocean wave energy for generating electricity technology, can be used for the oceanographic observation equipment such as preventing seabed base.
Background technique
Ocean wave energy belongs to the cleanliness without any pollution renewable energy sources, there is great potential in the ocean wave energy exploitation, wave energy also is to contain one of the abundantest energy in the marine energy simultaneously, it is the marine energy of exploitation of marine energy research most study near-mid term, it is ripe that its evaluation and exploration technology has been tending towards, entering or close to the commercialized development stage.
Float is the most frequently used mode of wave energy conversion, has conveniently advantage of the wave energy of collection, but often there are the problems such as the efficient of transformation of energy is poor in existing Floater Structure, and the not exclusively suitable irregular form of energy of ocean wave of most floats, when paying attention to absorbing unidirectional amount wave energy, be faced with the difficult problem that parts bear rigid impulse, and revolving float just can be evaded these problems to a certain extent, and has higher energy absorption efficiency.
And the follow-up energy conversion device of existing Wave energy converting device is not satisfactory, and hydraulic transmission adopts hydraulic oil as driving medium as it simple in structure of the words of converting system, the energy transmission is stable and efficient is high, it is ripe that modern hydraulic technology has been tending towards, and cost is low, good reliability.Can reach the stable delivery of energy by the application of various valve bodies, adopt simultaneously energy storage device to collect because the relatively more sufficient unnecessary hydraulic energy of stage of wave energy, can supply replenishing of inadequate stage of wave energy, last whole hydraulic system can be made closed, improved the vital capacity of whole system under ocean environment, so the combination of float and hydraulic energy should be a kind of method of collecting wave energy simple and effectively.
Summary of the invention
The purpose of this utility model is to provide a kind of device that utilizes wave-energy power generation, especially by the float conversion of wave can after be converted to mechanical energy at the electricity generating device that further is converted to hydraulic energy, guaranteed the stability of electric energy conversion.
The utility model comprises a buoyancy aid that floats on the sea, ocean wave energy drives the float rotation, float links to each other with the hydraulic driving bar, and float rotates drive hydraulic driving bar and moves up and down compression hydraulic oil, and last hydraulic oil enters hydraulic system drive oil hydraulic motor and generates electricity.
The utility model has designed a kind of brand-new float, this buoyancy aid main body is circular, oblique projection is arranged at top, thereby when wave is made, can promote more efficiently oblique protruding part and drive the float rotation, when the protruding part of the inclination of float is pulled to b.s.l., can be subject to than the circular buoyancy larger in water of rule according to the whole float of Archimedes' principle, therefore the seawater protruding part that can promote to tilt comes back to more than the sea, has realized that so just ocean wave energy constantly is converted into the variation of the mechanical energy that float rotates.
The mode that the utility model adopts the rotation float to combine with hydraulic transmission, absorb fast ocean wave energy by rotary float and be converted to double-acting hydraulic cylinder mechanical energy, rear compression hydraulic oil enters hydraulic circuit, has accomplished that energy ocean wave is random, variable and that be difficult to constant output conveniently is converted to be easy to utilize and constant hydraulic energy.
The utility model has used the support leg mechanism of rigidity to replace the flexible rope structure that most of buoyancy aids adopt, this just can wave energy in the first conversion links of mechanical energy with wave energy in vector on the unnecessary direction of unwanted energy the impact of whole system is reduced to minimum, at a kind of pulley hinging structure of junction surface design of hydraulic driving bar and hydraulic cylinder piston, can satisfy the lateral displacement that circular float produces in rotary course simultaneously.
The utility model has comprised an energy-storing chamber device, has realized can replenishing system in the insufficient time period of wave energy in the storage of the wave energy excessive hydraulic energy that oil hydraulic cylinder produces in relatively sufficient time.
