Description
Technical field
The utility model relates to a kind of apparatus for generating electricity by wave force that vibrates the energy-absorbing mode, particularly relates to eliminating the gravitational equilibrium device of gravity to the shimmy sub-influence of vibration of energy-absorbing.
Background technique
Wave power generation is to utilize the energy of wave to realize generating.The energy of wave is to exist with the fluctuation form, and in order to utilize the energy of wave, apparatus for generating electricity by wave force is through absorbing Wave energy, convert thereof into mechanical energy, changing other form energies into by the mechanical energy dress again and realize generating.
In apparatus for generating electricity by wave force, absorbing the most direct method of Wave energy is to utilize wave to cause absorption systems vibration realizing energy-absorbing.Under absorption systems was in resonance state, the energy of from wave, drawing was maximum.Because the cycle of wave is longer, the general available wave cycle formed resonance in order to guarantee absorption systems under the excitation of wave between 3 seconds to 15 seconds; The rigidity of requirement system a little less than; But so just cause the shimmy son of absorption systems under action of gravity, to produce very big initial deformation displacement, this initial displacement is generally between 2 meters to 56 meters (straight-line oscillation), or 2 radians are to (pendulum-type vibration) between 56 radians; Therefore, effectively vibration system is difficult to constitute; On the other hand and since system stiffness a little less than, gravity is bigger to its influence during vibration, is prone to the generation strong nonlinearity, is difficult to the resonance state of the system that sets up.Based on the consideration of above-mentioned two aspects, must eliminate or reduce as far as possible the influence of gravity in the absorption systems to absorption systems.
Existing apparatus for generating electricity by wave force energy-absorbing form disunity, form is varied, and energy-absorbing efficient is low.Utilize the wave dipping and heaving to cause that the move up and down vibrating power-generation that produces of absorption systems in the electricity generating device is one of principal mode wherein.Energy-absorbing was most effective when known absorption systems was in resonance state.But, realize that absorption systems resonance is very difficult because the characteristic of wave changes often.Gravity caused that system is in the strong nonlinearity state when one of difficulty was violent oscillatory motion, and system is difficult to realize resonance.Just shimmy son gravitate all the time in the process of moving up and down does not have power to come the effect of balancing gravity wholly or in part, and what make absorption systems is difficult to form resonance state, and energy-absorbing efficient is low.
