Compared with the prior art, the wave power generation platform 1 comprises a platform connecting piece 40, at least two horizontal platforms 21, at least two vertical wave power generation units 10 and at least one horizontal linear power generation assembly 30; two adjacent horizontal platforms 21 are connected to each other by a platform connector 40 to form one integral platform 20; the vertical sea wave power generation units 10 are arranged in a spaced mode along the horizontal direction, each vertical sea wave power generation unit 10 comprises a vertical power generation body 11 and a peristaltic gate ring 12, the vertical power generation body 11 is arranged below the horizontal platform 21 along the vertical direction, the peristaltic gate rings 12 are arranged between the horizontal platform 21 and the vertical power generation body 11 along the vertical direction, the vertical power generation body 11 is connected to the horizontal platform 21 through the peristaltic gate rings 12, and the vertical power generation body 11 further swings relative to the horizontal platform 21 in the horizontal direction through the peristaltic gate rings 12; the horizontal linear power generation assemblies 30 are arranged between the vertical wave power generation units 10 along the horizontal direction, each horizontal linear power generation assembly 30 comprises at least three horizontal linear power generators 31, in each horizontal linear power generation assembly 30, the axial leads of the rotors of all the horizontal linear power generators 31 are arranged in a different plane, in two adjacent vertical power generation bodies 11, the rotors of the horizontal linear power generators 31 are connected with one vertical power generation body 11, and the stators of the horizontal linear power generators 31 are connected with the other vertical power generation body 11, so that the wave power generation platform is stable and reliable, simple in structure, high in power generation efficiency and convenient to build a large-scale wave power generation field.
It should be noted that, a plurality of horizontal platforms 21 are connected to form an integral platform 20, so as to increase the stability, the specific principle is described as follows:
on the sea level, if there is no wind wave, the sea wave power generation platform 1 is under gravity G and buoyancy FFloating bodyIs in a balanced state under the action of (1), and the draft of the buoyancy bin 112 is h0Namely:
G＝Ffloating body＝ρgsh0；
Wherein rho is the density of the seawater, g is the acceleration of gravity, and s is the sectional area of the buoyancy bin.
When there is a wave with a wave height A at sea level, the buoyancy chamber 112 is subjected to an upward thrust F assuming that a vertical wave power generating unit 10 is located at the wave crest of the wavePush awayNamely:
Fpush away＝FFloating body-G＝ρgsA；
The other vertical wave power unit 10 is in the trough of the waves, and the buoyancy chamber 112 is generally subjected to a downward pulling force FPulling deviceNamely:
Fpulling device＝FFloating body-G＝ρgsA。
When the horizontal platforms 21 are not connected to the integral platform 20, it is assumed that the mass of the single horizontal platform 21 is MSheetWhen the thrust is FPush awayWhen the pushing time is T, the platform obtains a speed V and generates an amplitude S to vibrate up and down, namely:
Fpush awayT＝MSheetV，
S＝VT＝FPush awayT2/MSheet＝ρgsA2/MSheet，
Thus, the amplitude of the up-and-down vibration of a single horizontal platform 21 is proportional to the wave height and the mass M of the horizontal platform 21SheetIn inverse proportion.
Thrust F of the vertical wave power generating unit 10 when the horizontal platforms 21 are connected as the integrated platform 20Push awayOr a pulling force FPulling deviceAre applied to the integral platform 20.
In a sufficiently large wave zoneThe number of the vertical wave power generation units 10 at the wave crest position is equal to that of the vertical wave power generation units 10 at the wave trough position, and the total resultant force F applied to the integral platform 20 by the vertical wave power generation units 10 is equal to that of the vertical wave power generation units 10 at the wave trough positionGeneral assemblyIs zero, i.e.:
Fgeneral assembly＝Σ(f1,f2,...fi...fn)＝0。
Therefore, when the horizontal platforms 20 are connected to form the integral platform 20, the mass of the integral platform 20 is increased, the resultant force applied to the integral platform 21 is reduced, and the integral platform 21 is more stable.
In addition, the linear generator is composed of a stator and a mover, when the stator and the mover generate linear relative motion, the stator generates induced current and outputs energy, and the induced current plays a damping role on the motion of the stator and the mover, and in particular, the vertical linear generator 113 and the horizontal linear generator 31 may be linear generator generators which convert the linear motion into relative rotation between the stator and the mover through a conversion mechanism, respectively, and the axial line of the mover of the horizontal linear generator 31 is the motion direction of the mover.
