Abstract
The utility model relates to an ocean generating device, and discloses a directly-driven wave power generation device for an ocean platform. The directly-driven wave power generation device comprises a stator and a rotor, wherein the stator comprise a segment of vertical guide rail (4) which is vertical to the ocean plane, and two support rods (5) which are parallel to the ocean plant plane and are connected with the two ends of the vertical guide rail (4); the stator is a wave energy capturing member (3); and the wave energy capturing member (3) passes through the vertical guide rail (4). Due to the adoption of the directly-driven wave power generation device, captured wave energy can be used for directly driving a generator; and the directly-driven wave power generation device has the advantages of simple structure, convenience in supplying power, full utilization of the energy of wave, and reduction in ocean pollution.
Description
Technical field
The utility model relates to ocean power generating device, relates in particular to a kind of direct-drive type wave energy electricity generating device for ocean platform.
Background technique
Ocean platform generally adopts diesel-electric set electric supply, and power supply system volume, weight are larger, and the fuel transport distance is generally also longer, causes power cost higher, and easily ocean environment is polluted.
Most Wave energy converting devices are comprised of three grades of energy transfer mechanisms: the one-level energy transfer mechanism converts wave energy to the mechanical energy of certain carrier, the transformation of energy that the secondary energy transfer mechanism obtains the one-level transformation of energy becomes the mechanical energy of rotating machinery, and three grades of energy transfer mechanisms convert the mechanical energy of rotating machinery to electric energy by generator.And there is not the secondary energy transfer mechanism in electricity generating device of the present utility model, and the wave energy of capturing can direct drive generator, is converted to electric energy.
Summary of the invention
The utility model is for the deficiencies in the prior art, provides that a kind of cost is low, structural volume is little and the direct-drive type wave energy electricity generating device that is used for ocean platform of unlikely befouling environment.
The direct-drive type wave energy electricity generating device that is used for ocean platform, comprise stator and mover, stator comprise one section with vertical upright guide rail and two struts parallel with the sea level and that be connected with the upright guide rail two ends in sea level, mover is that wave energy is captured member, and wave energy is captured member and run through upright guide rail.
As preferably, the utility model adopts linear electric motor, the wave energy direct drive generator mover of capturing.
As preferably, oscillating floater is column, and the bottom is tapered, can better capture wave energy.
As preferably, adopt closedown structure between the mover of linear electric motor of the present utility model and the stator, after the amplitude of mover value beyond the mark, be automatically locked, linear electric motor are destroyed in the time of can preventing billow.
As preferably, it is oscillating floater that wave energy is captured member, and oscillating floater is positioned at the sea level, and top is positioned on the sea level, and the bottom is positioned under the sea level.
As preferably, strut is welded to connect away from an end of upright guide rail and the base of ocean platform side.By welding, connecting stator and ocean platform are welded as the low-intensity welding, and above after a certain boundary, welding destroys, not the induced damage resistive platform when stressed.Extreme sea condition can weld electricity generating device later again.
The utility model can be realized wave energy to the direct driving of generator unit stator, and is simple in structure, convenient power supply, and utilize ocean wave energy nearby, reduce marine pollution.

Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is the described partial enlarged drawing of the A of Fig. 1;
Fig. 3 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail, the following stated only is preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Be used for the direct-drive type wave energy electricity generating device of ocean platform, comprise stator and mover.
Stator comprise one section with the vertical upright guide rail 4 in sea level with are connected a strut 5 parallel with the sea level that is connected with upright guide rail 4 two ends, stator passes the mover that floats over the sea level, mover is up-down vibration under the effect of wave, according to the principle of linear electric motor, the wave energy that mover is captured is converted into electric energy.Strut 5 is connected away from the base 7 of reserving on an end of upright guide rail and the ocean platform 6, avoids being connected with the direct of ocean platform 6; Strut 5 welds with the employing that is connected of base 7, and the low-intensity welding of base 7 can make stressed above after a certain boundary, and welding destruction is protected ocean platform 6 unlikely infringements.
Mover is that wave energy is captured member 3, and it is oscillating floater that wave energy is captured member 3, and it is cylindric that oscillating floater is, the bottom is taper, and such structure can better be captured wave energy, and oscillating floater is arranged in seawater, its top is positioned on the sea, and the bottom is positioned under the sea.
For preventing that the billow timer from destroying, linear electric motor adopt closedown structure, in the time of mover amplitude value beyond the mark, are automatically locked.
Wave energy is captured member 3 and is captured wave energy, and oscillating floater is in upright guide rail 4 vibration, by the interaction of mover with the stator generation, the mechanical energy of mover straight line is converted into electric energy.
