Description
Technical field
The present invention relates to a kind of ocean energy collection method and device.
Technical background
In the face of serious day by day energy scarcity and the environmental pollution that is on the rise, people are renewable for exploitation, clear energy sources is technological more and more pays close attention to, and ocean energy provides huge energy sources for we mankind.For the energy that guarantees necessary for human obtains stable and lasting supply, countries in the world all make great efforts to make energy resource structure from single conventional energy resource to multiple new energy transition.Wide ocean accounted for earth surface long-pending 70%, concentrated 97% the water yield, containing a large amount of energy, comprising wave energy, tidal energy, thermal gradient energy, salt error can etc.(1) wave energy is meant kinetic energy and the potential energy that the ocean surface wave is had. the energy of wave and wave height square, cycle of motion of wave and the width of meeting the corrugated be directly proportional; In fact the size of wave power is also relevant with many factors such as wind speed, wind direction, the time of drying continuously, flow velocitys, so wave energy is the least stable a kind of energy of energy in the marine energy.(2) the present application technology comparative maturity of tidal energy, because existing a lot of years of its research is historical, many power station development projects of Britain, France, Canada and Russia and design demonstration have reached decades, the longest existing seventy or eighty years.The sixties in 20th century, first commercial power station was built up in France; Tidal power generation seventies technology begins to get into the production of large-scale commercial applications property and is purpose, is the scientific research demonstration stage of target to reduce cost, and the tidal power generation technology is walked in the ocean energy development technique in prostatitis.(3) thermal gradient energy of sea water is meant the heat energy of water temperature difference between self-restraint surface seawater and the deep sea water, is a kind of important form of ocean energy.The sea surface temperature of low latitudes is higher, has temperature difference with deep layer cold water, and is storing temperature difference heat energy, and its energy is directly proportional with the size and the water yield of the temperature difference.The greatest difficulty of thermal gradient energy utilization is a temperature difference size, and energy density is low, and its efficient only has about 3%, and heat exchange area is big, and construction cost is high, and various countries are still in trying to explore at present.(4) the chemical potential difference between the seawater that salt error can be meant between seawater and the fresh water or two kinds of salt concentrations are different can, be the ocean energy that occurs with the chemical energy form.The main existence and the He Hai jointing place.Simultaneously, the salt lake and the underground salt mine in the abundant area of fresh water also can utilize the salt error ability.Salt error can be the maximum a kind of renewable energy sources of energy density in the ocean energy.But generally, research that can this new energy to salt error also is in the laboratory experiment level, also has long distance from Demonstration Application.Present exploitation of marine energy situation; Though the energy of ocean energy is very big; But can be considerably less by what people utilized, the ocean energy energy conversion device kind that people designed is very many, but can also not have by really effective device; Reason just is that the energy flux density of ocean energy is smaller, and ocean energy has unsettled characteristic.The method of typically ocean energy being carried out cumulative has wave energy or tidal energy utilization tapered channels that seawater is delivered to the method that certain altitude forms potential difference.But the height that utilizes this method to promote seawater is limited, therefore only relies on the seawater potential difference of lifting height to come the cumulative method also to be nowhere near.Analyze current ocean energy development and utilization situation and be not difficult to find out, want to make the smaller ocean energy of energy flux density to increase substantially energy density, it is most important to the development and use ocean energy to design a kind of effective cumulative device.
