Description
Technical field
The present invention relates to a kind of wave-power device, particularly to a kind of maritime floating platform float-type wave-activated generator.
Background technology
In ocean, the huge energy is all contained in the tide is flowing and ebbing, ocean current flowing, heaving of the sea, in today of energy growing tension, marine energy is a huge treasure-house, ocean tidal power, wave energy cleanliness without any pollution, and potential is huge, and at present people are to can also the exploitation of the energy also be only a drop in the ocean.And on the other hand, some build afloat platform, can only be from Long-distance ground power transmission, not only power transmission cost is high, and power transmission risk is also big, if using diesel-driven generator generating, cost of electricity-generating is more preferable.For these offshore platforms, the wave of platform periphery and ocean current all contain the huge energy, generate electricity if can develop and utilize, and can replace the electricity consumption of a part, can effectively reduce electric cost.
CN103423072A patent application document disclosed in Patent Office of the People's Republic of China's December in 2013 4 days, entitled Novel shock float-type ocean wave energy power generation, this device utilizes float to lift, promote the gear rack elevating above float, then by rack drives pinion rotation, gear drives generator rotation memory to generate electricity after speedup.Although this device uses ratchet to achieve lifting Bidirectional driving, but use speed increaser and the electromotor of single set, when rotating is changed, needing to overcome by force the rotator inertia of motor and speed increaser, energy loss is big, affects generating efficiency, and the connecting rod that this device float drives is upper and lower vertical motion, and wave exists horizontal motive force, the connecting rod of float can be produced bigger shearing force, the most stuck.
Summary of the invention
It is an object of the invention to solve appeal float TRT motor in synchrony during float rises and falls turn to, not only lack the utilization to generator rotation inertia, and need to overcome rotator inertia, cause the low problem of generating efficiency, it is provided that a kind of efficient maritime floating platform float-type wave-activated generator.
Meanwhile, and invent the fork connection float also utilizing inclination, utilize the angle of fork and float to change, drive float one end to generate electricity simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of maritime floating platform float-type wave-activated generator, including the electromotor being arranged on the bank and setting float across the sea, the rotor coaxial of described electromotor connects gear, connected by fork between described float and gear, it is hinged in the middle part of fork on the bearing on bank, one end that fork pulls in shore is the fan tooth engaged with gear, the other end of fork is rotatably connected on float, the both sides of described gear are connected by ratchet respectively electromotor, the ratchet of described gear both sides is respectively the contrary forward ratchet of driving direction and reverse ratchet.When float floats, by fork driven gear main story, gear drives the generator amature of side to rotate forward generating by forward ratchet；When float sinks, by fork driven gear anti-pass, gear drives the generator amature of opposite side to rotate backward generating by reverse ratchet, and meanwhile, the inertia of the electromotor utilization rotated forward itself persistently rotates generating；When same float second time floats, counter-rotational electromotor utilizes inertia persistently to rotate.When heaving of the sea amplitude diminishes, when the rotating speed that rear float sink-float driven gear rotates is less than generator amature inertia rotating speed, due to the effect of ratchet, electromotor will not be played and counter drag obstruction by gear.
As preferably, described generator amature rotating shaft is all stretched out as drive end at electromotor two ends, multiple electromotors and multiple gear spaced series on the coast are arranged, multiple and gear float one to one it is set side by side with on sea, it is provided with ratchet between adjacent electromotor and gear, and the ratchet driving direction at same electromotor two ends is identical.The float being set up in parallel on sea asynchronously fluctuates, and drives the asynchronous rotating forward of each gear on the bank or reversion, and same generator amature rotating shaft two ends are all stretched out as drive end, are driven by two gears at electromotor two ends respectively.Same electromotor two end ratchet direction is consistent, and for gear, it is contrary that the ratchet direction, the left and right sides of two adjacent gears is arranged.It is spaced such that in-line layout, it is ensured that stablizing of generated energy, forms complementation can to again different floats, make full use of each float and motor.
As preferably, it is provided with two ratchets in the same direction between the electromotor of described gear and gear side, between two ratchets, is provided with speed increaser.Speed increaser is the gear ratio variator more than, and planetary gearsets or full depth tooth wheels can be used to realize.When pinion rotation, first pass through ratchet and drive speed increaser, after then being increased rotating speed by speed increaser, drive generator amature by ratchet.So when float drifts along conversion, the speed increaser of gear and original side disengages, and reduces commutation resistance, also avoids speed increaser by excessive impact.And speed increaser damping itself is big, when generator amature relies on inertia to rotate or relies on the input of electromotor other end power, can disengage in time, it is ensured that generating efficiency.
As preferably, the fan tooth of one end that described fork pulls in shore is with fork pivoting support as axle center.Between fan tooth itself and gear, there is bigger gear ratio.
As preferably, stretch in float after the described fork of float one end and the side walls hinged of float, swing link end part in float is fan tooth, is provided with and fans tooth meshed gears in float, and gear both sides pass through the contrary forward ratchet of driving direction respectively and the connection of reverse ratchet has electromotor.Fork is obliquely installed connection float, and when float drifts along, the angle of fork and float produces change, utilizes this angle to change, and stretching into the fan tooth of the fork in float can relatively rotate, and drives the pinion rotation in float, and is converted to the energy of electrical power generators.
As preferably, it is provided with two ratchets in the same direction between gear and the gear side electromotor in float, between two ratchets, is provided with speed increaser.
As preferably, the generator amature rotating shaft outer end in described float is protruding, and is provided with flywheel in generator amature rotating shaft outer end.After gear rotates backward, when ratchet departs from, generating function utilizes the big rotator inertia of flywheel, keeps longer rotation time, generates electricity.
