The accompanying drawing explanation
Fig. 1 is the artificial submarine structure schematic diagram that the present invention is fixing for floating marine formula wave-power device.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details.
The specific embodiment
Consult shown in Fig. 1, for floating marine formula wave-power device, fixing artificial seabed can be the hollow buoyancy aid 3 of an arbitrary shape in the present invention, its displacement deducts his weight of self should be greater than the pressure that it need bear, and its tensile strength should be greater than the buoyancy that wave-power device makes progress." artificial seabed " hollow buoyancy aid 3 be with one group of anchor chain or hawser 4 moorings on the heavily stone roller 5 in seabed, heavily cut or polish jade with an emery wheel the buoyancy that 5 weight should be greater than wave-power device.Wave-power device 1 is hinged by omnidirectional mechanism 2 and " artificial seabed " hollow buoyancy aid 3.
The concrete method of implementing is as follows:
1) at first choose applicable heavily stone roller: according to the weight and volume parameter of floating type wave-power device self and the suffered buoyancy of this floating type wave-power device of depth calculation in marine site, place, the heavily weight of stone roller of choosing should be greater than the suffered buoyancy of floating type wave-power device;
2) build artificial seabed: make a hollow buoyancy aid, can the side's of being body, any shape such as spherosome, cylinder, only need to meet: the weight that the displacement of this hollow buoyancy aid deducts himself is greater than the pressure that it bears in selected marine site, and its tensile strength is greater than the buoyancy of floating type wave-power device simultaneously; And install an omnidirectional mechanism for being connected with the floating type wave-power device in the upper end of hollow buoyancy aid;
3) connecting components: at first by one group of anchor chain of the hollow buoyancy aid second line of a couplet or hawser, each lower end of this group anchor chain or hawser gather again for one and with heavily the stone roller be connected; The omnidirectional mechanism that the lower end of floating type wave-power device and hollow buoyancy aid upper end are installed is hinged;
4) the above-mentioned single unit system assembled is sunk in the sea, finally make heavily to cut or polish jade with an emery wheel and be placed in seabed, single unit system is uprightly moored on seabed, starts life's work.
Principle of work of the present invention and process are: when unidirectional acting, floating type wave-power device 1 is subject to the effect zero load of wave energy to rising; When reaching ripple when protruding, on its floating type wave-power device 1, main body produces relative shift length with the acting parts on being fixed on " artificial seabed " hollow buoyancy aid 3; When wave protruding during to the recessed motion of ripple by ripple, be that the inertia that the wave-power device utilization moves downward is exerted pressure and done work to " artificial seabed " hollow buoyancy aid 3 by the acting parts, the function of its pressure that bears is the buoyancy by self, when not bearing pressure, its buoyancy is by the anchor chain of bottom, or hawser absorbs, when bearing pressure, bear great pressure and can offset the bottom anchor chain simultaneously or pull the pulling force that rope is identical to it.
When two-way work doing, workflow is: floating type wave-power device 1 rises with workload under the wave energy effect, drive electrical generator, now anchor chain or hawser bear two kinds of pulling force: 1. the rising buoyancy that is " artificial seabed " hollow buoyancy aid 3,2. the power of floating type wave-power device on-load acting, reach ripple when protruding wave-power device 1 in a high position, laid in high potential energy, wave energy disappears, and it utilizes the inertia acting of self downward movement to drive electrical generator.
The various embodiments described above can some variations in addition under not departing from the scope of the present invention, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection domain of the present patent application patent.
