Description
Technical field
The utility model relates to the wind power technology field, particularly relates to a kind of independent-lifting tidal power generating unit.
Background technique
Enter 21 century, in the face of conventional energy resource is exhausted, the pressure of environmental deterioration, the task of face energy-saving and emission-reduction again simultaneously, developing the economy, it is extremely urgent to seek the substitutability green novel energy source.The marine tidal-current energy generating is a kind of generation mode that utilizes morning and evening tides kinetic energy, rotates the generating of drive generator thereby promote water turbine by the energy that marine stream produces.Marine tidal-current energy is a kind of as green energy resource, because of advantages such as its recyclability are good, predictability is strong, clean environment firendly, reserves are abundant, becomes the object that countries in the world fall over each other to research and develop.The tidal power generating unit is the capital equipment of tidal power generating, and its performance directly affects efficient and the quality of tidal power generating.
A kind of typical tidal power generating machine set system comprises two generators, two generators drive the two ends that one group of impeller is fixed on same horizontal gird separately, horizontal beam is installed in one and erects on the steel structure tower cylinder, two generators just in time are distributed in tower cylinder both sides, be provided with the ratchet elevator structure between tower cylinder and the horizontal beam, can regulate the position of horizontal gird on the tower cylinder by this elevator mechanism, so that generator can be in the work of the depth of water place of the best.When tidal power generating unit place breaks down or in case of emergency, hydraulic jack or the work of air pressure oil cylinder driving pawl elevator mechanism drive horizontal gird and vertically rise from the water surface along the tower cylinder, are convenient to maintenance or safeguard.
Above-mentioned tidal power generating unit is realized promoting and descending by the ratchet elevator structure, this elevator mechanism is comparatively complicated, and the both sides generator set is to promote simultaneously or descend, even one-sided generator set needs repairing, also must promote simultaneously two generator set, affect without reason the normal operation of opposite side unit, affected the generating efficiency of tidal power generating unit, increased maintenance cost.In addition, because the existence of marine growth or floating marine thing, the horizontal anomalous movement beam is adhered to by marine growth easily with vertical tower cylinder, thereby or clog it and connect the lifting that slit affects horizontal beam, and the lifting of horizontal beam is unfavorable for anti-corrosion of metal equally to the friction that the tower cylinder produces, and causes maintenance cost to increase.
Another kind of typical tidal power generating machine set system comprises two generators, two generators respectively carry one group of impeller and are fixed on two horizontal gird two ends, the other end of horizontal gird is hinged on the setting steel structure cylinder, two generators just in time are distributed in the steel cylinder both sides, the end that horizontal gird is installed generator set connects with wire rope respectively, the power plant on the other end vertical connecting steel cylinder top of wire rope, the steel cylinder top exceeds the sea level.Two horizontal girds can be around the articulating point circle swing under the traction of wire rope, and when being rocked to a high position, generator set exposes the sea, can carry out maintenance maintenance work.Two generators can independent lift land, and normal operation is independent of each other.
Although above-mentioned tidal power generating unit can make two generator independent lift descend, structure is also very simple, reduced to a certain extent maintenance expenses, but because be to be hinged on the vertical steel column, two horizontal girds are again to connect the steel column top by wire rope, therefore when the ocean current of vertical direction motion appearred in ocean environment, wire rope can not be born the power that vertically makes progress, and therefore the phenomenon of " with the stream pendulum " appears in hinged crossbeam easily.Even braking device is installed in the hinged place, vertical direction shakes also easily fatigue ruption braking device frequently.In addition because articulated mounting is positioned under the sea, as break down be unfavorable for the maintenance.
