Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
In conjunction with Fig. 1-3, the present invention include floatation type fan platform, inhale wave float 1., buffer spring 3., linear electric generator,
Floatation type fan platform include platform leg 2. with strut 6., linear electric generator include stator 4. with mover 5..Floatation type blower
Platform is to refer to, which can be used for other marine structures such as ocean platform.
It is 1. main there are two effect to inhale wave float, one be to provide fan platform needed for buoyancy, second is that absorb wave energy,
Wave energy is converted into the mechanical energy of displacement；3. buffer spring plays movement buffer function, increase the kinetic damping of fan platform；
Fan platform is used to support blower, including platform leg 2. with strut 6.；Linear electric generator include mover 5. with stator 4., mainly
There are two effects, first is that the mechanical energy that suction wave float is converted, is converted to electric energy by power generation, second is that increasing the movement resistance of fan platform
Buddhist nun.As shown in Fig. 2, when in hydrostatic, inhale wave float 1., buffer spring 3., platform leg 2., the mover of linear electric generator 5. and
Stator 4. concentric vertical placement, the lower end of buffer spring are fixedly mounted on the top for inhaling wave float, and upper end is fixedly mounted on flat
Platform spud leg inside top, the stator of linear electric generator are fixedly mounted at the top of platform leg, and it is fixed that the mover of linear electric generator passes through
Son and buffer spring, lower end, which is fixedly mounted on, inhales wave buoy top.The buoyancy of structure is mainly provided by suction wave float, inhales wave float
For absorbing wave energy, wave energy is converted into mechanical energy of its own movement, inhale wave float shape be it is unfixed, can be with
It is optimized according to concrete condition when using；Relative motion is generated between fan platform and suction wave float, wave energy is absorbed, plays
Subtract the effect of shaking.In addition, buffer spring plays buffer function to the movement for inhaling wave float, prevent its movement from acting directly on blower flat
On platform, buffer spring increases the kinetic damping of fan platform, reduces the motor imagination of fan platform.
The course of work of the invention is as follows:
Under wave action, it inhales wave float and absorbs wave energy, wave energy is converted into the mechanical energy of its own movement, inhale
Relative motion is generated between wave float and fan platform spud leg, buffer spring plays buffering and inhales between wave float and fan platform
The effect of relative motion avoids and inhales wave float and fan platform direct interaction, while increasing the movement of fan platform
Damping, can reduce the motor imagination of fan platform.Since the stator of linear electric generator is fixedly connected with platform leg, mover and
It inhales wave float to be fixedly connected, therefore, under wave action, generating relative motion between fan platform and suction wave float can be such that straight line sends out
Relative motion is generated therewith between the mover and stator of motor, is produced electricl energy, and the mechanical energy of suction wave float is partly converted into
Electric energy reduces to realize absorption wave-energy power generation and inhales the energy that wave float acts on fan platform.Linear electric generator
During mover and the mutual movement power generation of stator, damping is generated between the two, prevents the mutual movement of the two, and it is flat to increase blower
The kinetic damping of platform prevents the movement for inhaling wave float to act directly on fan platform, reduces the motor imagination of fan platform,
Buffer spring is all prevented by stretching the relative motion between compression prevention suction wave float and platform leg, both modes
Wave float and platform leg direct interaction are inhaled, the kinetic damping of fan platform is increased, reduces fan platform under wave
Motor imagination, improve working efficiency and the safety of blower.The wave energy energy absorbed from the angle analysis of energy, fan platform
There is the mechanical energy for being wholly converted into fan platform, but, a part is converted to electric energy, and a part is converted to buffer spring
Potential energy, a part are converted to the mechanical energy of fan platform movement, lead to the reduction of its motor imagination.
To sum up, the present invention shakes there are two effect first is that subtracting, and reduces the motor imagination of floatation type blower under the wave action,
Second is that power generation, absorbs wave energy, wave energy is converted into electric energy.Buffer spring and linear electric generator can play the role of subtracting shaking,
The kinetic damping of floatation type fan platform is increased, can reduce the motor imagination of floatation type fan platform under wave action；It inhales
Wave float absorbs wave energy, wave energy is converted into the mechanical energy of its movement, and the mechanical energy for inhaling the movement of wave float is sent out by straight line
Motor is converted into electric energy.The present invention can effectively reduce motor imagination of the floatation type fan platform under wave, make at blower
In more stable working condition, working efficiency and the safety of blower are improved.It is contemplated that the present invention may be use with ocean platform etc. its
The marine structure of his type.
