Embodiment embodiment: as shown in the figure: 1, chinampa; 11, floating body; 12, framework; 13, supporting frame; 14, working platform; 2, hydraulic system; 21, hydraulic integrated system; 22, oil cylinder; 23, thick stick floats work system; 231, float; 232, guide shaft; 3, control system; 4, anchoring fixed system; 41, anchor cable; 42, counter weight device; 5, electrical system; 51, generator; 52 oil hydraulic motors.
The present invention includes chinampa 1 as shown in Figure 1 and swim in the water surface by anchoring fixed system 4 is stable, its stream line 41 one end is fixed on the other end bottom chinampa 1 and is fixed on seabed counter weight device 42, the fixing chinampa 1 that is flexible coupling that the present invention adopts anchor cable such, object ensures chinampa and whole equipment group, under the impact of typhoon and billow, compliant motion is kept to slow down impact dynamics, to guarantee the safe operation of unit; In addition, unloading of anchor cable draws fixed-direction also can ensure the motion amplitude of unit is reduced, and so just substantially increases the ability to ward off risks of whole electricity generating device.
Hydraulic integrated system 21 in hydraulic system 2, electrical system 5 and control system 3 are fixed on the working platform 14 on chinampa 1; Whole unit is formed a whole, chinampa 1 auxiliary under, can raise with the rising of horizontal plane, reduce and reduce, therefore just reducing because tidal range changes the damage to rapid wear accessories such as generators caused.Oil cylinder 22 is arranged on the outward extending supporting frame 13 in edge, chinampa 1, and thick stick floats the multiple thick sticks arranged in work system 23 and floats unit and be connected with each oil cylinder 22 respectively;
Be illustrated in figure 2 the pie graph on chinampa 1, mainly comprise several floating bodies 11 of framework to be closely fixed together side by side by framework 12, generally, the net buoyancy of structure is not less than 30% of overall gravity, and be not less than 200KN, to ensure that unit has enough little amplitude of fluctuation under swing state.The making materials'use anti-corrosion material of floating body 11, and pressing force containers demand makes, and carries out pressure test after completing.
Chinampa 1 utilize framework be laid on floating body 11 form plane on, form a working platform 14, working platform 14 is in the horizontal plane floating, is preferably set in distance above water 3 meters, object is less in order to ensure to be subject to wave punching filling number of times, reduces the impaired probability of easily damaged parts; Working platform 14 carries out strong sealing structure in working process, and inside also possesses drainage, guarantees to run into when billow is unavoidable is poured water, can discharge ponding as soon as possible, reduce seawater to the damage of easily damaged parts as far as possible; The above-mentioned easily damaged parts mentioned the mainly electric component such as motor, oil hydraulic motor.Framework 14 stretches out and forms supporting frame 13, and supporting frame 13 floats work system 23 and oil cylinder 22 for fixing thick stick.
Be illustrated in figure 3 the schematic diagram that the present invention utilizes wave-energy power generation, comprise the oil cylinder 22 of dispersed placement, balance the hydraulic integrated system 21 that oil pressure also stablizes output oil pressure, hydraulic integrated system 21 is connected with oil hydraulic motor 52;
As shown in Figure 4, thick stick floats work system 23 and distributes in the form of a ring and be fixed on the supporting frame 13 on chinampa 1, when wave floats work system from a side impact thick stick of ring structure, thick stick floats work system and side then can be kept floating larger, and float less or do not move in side relatively, the hydraulic pressure size so just making hydraulic integrated system 21 collect remains at a level, can not occur that oil pressure change is excessive because of the size of tidal range or stormy waves, and the phenomenon of uncontrollable even system crash.
As shown in Figure 5, thick stick floats work system and mainly contains multiple thick stick and float unit composition, and each thick stick floats the float 231 that contour structure that unit is provided with a bottom is interior hyperbola pattern, and plays two guide shafts 232 of positioning control effect when working to float 231; In order to ensure the operating life of float 231, between guide shaft 232 and float 231, be provided with the sliding sleeve that high-abrasive material is made; Float 231 under wave action, moves up and down, and guide shaft 232 is motionless relative to float 231, and material and the sliding sleeve of guide shaft 232 influence each other, and are therefore chosen as the material that a hardness is higher, and sliding sleeve selects the material wear-resisting compared with soft egg.
When float 231 receives wave upwards thrust, promote oil cylinder piston to move upward, the oil of oil cylinder is squeezed, produce pressure, this pressure is generally not less than 2Mpa, this pressure is delivered to hydraulic integrated system 21, and after the different time different pressures coming from multiple oil cylinder carries out balancing and cushion by hydraulic integrated system 21, become the pressure oil of comparatively steady pressure and flow, this pressure oil drives oil hydraulic motor 52 to work, the rotating speed of oil hydraulic motor 52 is comparatively stable, oil hydraulic motor 52 drives generator 51 to work, generator 51 sends comparatively stable electric energy, this electric energy is distributed by control system 3, a part is stored in battery, another part is used for electrical system self electricity consumptions such as generator 51.
