The present invention includes as shown in Figure 1 chinampa 1 by the stable water surface that swims in of anchoring fixed system 4, its stream line 41 one end are fixed on the chinampa 1 bottom the other end and are fixed on seabed counter weight device 42, the present invention adopts the so fixing chinampa 1 that is flexible coupling of anchor cable, object is to guarantee chinampa and whole equipment group, under the impact of typhoon and billow, keep compliant motion to slow down impact dynamics, to guarantee the safe operation of unit; In addition, unloading of anchor cable draws fixed-direction also can guarantee to make the motion amplitude of unit to reduce, and so just greatly improved the ability to ward off risks of whole electricity generating device.Hydraulic integrated system 21, electrical system 5 and control system 3 in hydraulic system 2 is fixed on the working platform 14 on chinampa 1; Whole unit is formed a whole, under chinampa 1 auxiliary, can raise with the rising of horizontal plane, reduce and reduce, therefore just reduced to change because of tidal range the damage to rapid wear accessories such as generators causing.Oil cylinder 22 is arranged on the 1 outward extending supporting frame 13 in edge of chinampa, and the floating unit of multiple thick sticks arranging in the floating work system 23 of thick stick is connected with each oil cylinder 22 respectively;
Be illustrated in figure 2 the pie graph on chinampa 1, mainly comprise that several floating bodies 11 of framework are 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 guarantee 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 container requirement making, carry out pressure test after completing.
Chinampa 1 is utilizing framework to be laid in the plane that floating body 11 forms, form a working platform 14, working platform 14 swims on horizontal plane, is preferably set in above water 3 meters of distances, object is less in order to guarantee 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 that billow is unavoidable while being poured water, can discharge as soon as possible ponding, reduces the damage of seawater to easily damaged parts as far as possible; The above-mentioned easily damaged parts of mentioning is mainly the electric component such as motor, oil hydraulic motor.
Framework 14 stretches out and forms supporting frame 13, and supporting frame 13 is for the floating work system 23 of fixing thick stick and oil cylinder 22.
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, the hydraulic integrated system 21 that balance oil pressure is also stablized output oil pressure, hydraulic integrated system 21 is connected with oil hydraulic motor 52; As shown in Figure 4, the floating work system 23 of thick stick distributes in the form of a ring and is fixed on the supporting frame 13 on chinampa 1, in the time that wave floats work system from a side impact thick stick of ring structure, it is larger that the floating work system of thick stick can keep a side to float, and a relative side is floated less or is not moved, so just make the hydraulic pressure size that hydraulic integrated system 21 is collected remain at a level, can because of the size of tidal range or stormy waves, to occur that oil pressure changes not excessive, and the phenomenon of uncontrollable even system crash.As shown in Figure 5, the floating work system of thick stick mainly contains the floating unit of multiple thick sticks composition, and the contour structure that the floating unit of each thick stick is provided with a bottom is the float 231 of interior hyperbola pattern, and plays two guide shafts 232 of positioning control effect when float 231 is worked; In order to guarantee 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 the effect of wave, moves up and down, and guide shaft 232 is motionless with respect to float 231, and material and the sliding sleeve of guide shaft 232 influence each other, and is therefore chosen as a material that hardness is higher, and sliding sleeve is selected the material wear-resisting compared with soft egg.
When float 231 is received upwards thrust of wave, promoting oil cylinder piston moves 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 hydraulic integrated system 21 carries out the different time different pressures that comes from multiple oil cylinders after balance and buffering, become the comparatively pressure oil of 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 distributes by control system 3, a part is stored in battery, another part is for electrical system self electricity consumptions such as generators 51.
