Abstract
The invention discloses a surfing-type wave generating device and method. The surfing-type wave generating method comprises the following steps of: automatically opening a gate leaf of a water inflow gate under the coaction of wave force and water pressure in the case of wave rise so that seawater enters a reservoir and is stored; automatically closing the water inflow gate when the external pressure of the water inflow gate is smaller than the internal pressure; automatically opening a water outflow gate when the internal water pressure of a water outflow gate is greater than the external water pressure, enabling the seawater of the reservoir to flow into a tail water tank through a runner and be drained through the water outflow gate so as to propel a hydraulic generator to generate electricity; and automatically closing the water outflow gate when the internal water pressure of the water outflow gate is smaller than the external water pressure. The surfing-type wave generating device and method provided by the invention have the advantages of high energy utilization rate, simple structure, investment saving, convenience of operation, environmental friendliness, and the like, can adapt to extreme climate conditions and unknown natural conditions and have great research and popularization values.
Description
Technical field
The invention belongs to the exploitation of marine energy field, particularly a kind of surfing type wave-type electric generator and method.
Background technique
Along with society growing to energy demand, gradually exhausted as nonrenewable resourceses such as the coal in main energy sources source, oil, rock gases, too high " greenhouse effect " that bring of CO2 emissions and the negative effect that environment damage produced is on the rise.Energy crisis and environmental pollution have become the significant problem that human development is faced, and the renewable energy sources of development cleaning is known together by countries in the world.At present, countries in the world are all in the development and utilization work of actively carrying out clean renewable new energy.Wave energy is to contain one of the abundantest energy in the ocean as a kind of reproducible ocean energy, and the theoretical value of whole world wave energy is about 10
9The kW magnitude is hundreds of times of present world generated energy, and wide commercial prospect is arranged, thereby also is one of emphasis of various countries' ocean energy research and development.That wave energy has is widely distributed, energy flux density big, advantages of environment protection.Make full use of wave energy,, have great realistic significance for improving energy resource structure, reducing the negative effect of fossil energy to environment.
Wave-activated power generation normally at first adopts converter that wave energy is converted to mechanical energy with practical value, again mechanical energy is converted to electric energy.Corresponding wave-type electric generator type mainly contains the combination between oscillating type, float type, three kinds of modes of unrestrained more formula and the three.Wave-activated power generation equipment exploitation country the earliest is a France (1910) in the world, at present, English, move, day etc. state the research of wave-activated power generation is leapt the most, it is one of national that China also is that main in the world wave energy is researched and developed.The principal element of restricting current wave-activated power generation commercialized development is that the utilization ratio of wave energy is on the low side and cost of investment electricity generating device is higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of surfing type wave-type electric generator and method are provided.
The surfing type wave-type electric generator comprises: wet pit, afterbay, runner, hydraulic turbine generator, inlet gate, go out sluice gate, wet pit is provided with inlet gate, afterbay is provided with out sluice gate, and wet pit is connected by runner with afterbay, is provided with hydraulic turbine generator on runner.
Described inlet gate adopts the suspension type hydraulic self-control gate.Describedly go out sluice gate and adopt the suspension type hydraulic self-control gate.
Surfing type wave-activated power generation method is: when ripple rises under the acting in conjunction of wave force and water pressure, the gate flap of inlet gate is opened automatically, seawater enters wet pit, wet pit holds receives seawater, when the external pressure of inlet gate during less than internal pressure, inlet gate is closed automatically, when the internal water pressure that goes out sluice gate during greater than external water pressure power, going out sluice gate opens automatically, the seawater of wet pit flows into afterbay through runner, discharges by going out sluice gate, thereby promotes the hydraulic turbine generator generating, when the internal water pressure that goes out sluice gate during, go out sluice gate and close automatically less than external water pressure power.
The present invention has utilized ripple to rise and the differential water pressures of ripple when falling, and fully absorbs wave energy, and can while collecting part tidal energy, energy by ocean current, trend energy, thereby improved the utilization ratio of ocean energy widely.Compare with wave-type electric generator in the past, this novel surfing type wave-activated power generation method and device have the energy utilization efficiency height, simple in structure, investment is saved, easy to operate, advantages of environment protection, the natural condition that can adapt to extreme weather conditions and address have research promotion and are worth.
