Description
Technical field
The utility model relates to the wind power plant field, and the capacity of referring in particular to can reach MW class and other Large-scale Wind Turbines of higher level, the compound vertical axis aerogenerator group of a kind of specifically half directly-drive permanent magnet.
Background technique
Existing wind power generating set is based on the horizontal axis wind-driven generator group basically.The generator major part of existing horizontal axis wind-driven generator group is all in the high-altitude of tens meters and even up to a hundred meters, tower frame strength, wind resistance etc. are required high, so corresponding increase of cost, the horizontal axis wind-driven generator group is subjected to many restrictions such as size, direction of wind-force in use in addition, and generating efficiency is low; Generation inertial force and gravity value are inconstant during the blade of horizontal axis rotation simultaneously, cause the blade fatigue life of horizontal axis short, fragile.The blade of the large-scale horizontal axis wind-driven generator group that MW class is above also must adopt and become the slurry control system, and this structural design is very complicated, and validity is required high especially, in servicely is out of order easily, and maintenance is also inconvenient, involves great expense.
Summary of the invention
The purpose of this utility model is the defective at prior art, provides a kind of wind energy utilization height, generated energy is big, overall cost is low, the life-span is long, be convenient to the compound vertical axis aerogenerator group of half directly-drive permanent magnet of installation and maintenance.
The purpose of this utility model solves by the following technical programs:
The compound vertical axis aerogenerator group of a kind of half directly-drive permanent magnet comprises generating head and impeller spindle, and the main shaft of described generating head links to each other with the step-up gear group, vertical the linking to each other of impeller spindle of step-up gear group and vertical placement; The lower end of described impeller spindle is stretched in the step-up gear group and is linked to each other with the step-up gear group.
Described generating head is evenly distributed on the outer side elevation of step-up gear group.
The main shaft horizontal positioned of described generating head also is on the same horizontal plane.
The upper end of described impeller spindle is provided with wind wheel.
The utility model has following advantage compared to existing technology:
Wind power generating set of the present utility model is not recognized wind direction, the startup wind speed is little, by using single step-up gear group can drive a plurality of generating heads, utilize the speedup principle of step-up gear group, improved the self generating amount of whole unit, reduce the cost of whole system simultaneously, improved the economic benefit of generator set.
Wind power generating set of the present utility model makes the center of gravity of whole unit move down because step-up gear group and generating head all are arranged on the bottom of wind wheel, and wind loading rating is strong, and is low to the requirement of strength of pylon, and is convenient to install and regular maintenance.
Wind power generating set of the present utility model simple in structure, floor space is little, and overall cost is low; And for the utilization ratio of wind energy height, generated energy is big, has bigger using value, can be used for the generating of large-scale wind electricity field.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1-generating head; 2-step-up gear group; 3-impeller spindle.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: the compound vertical axis aerogenerator group of a kind of half directly-drive permanent magnet comprises generating head 1, step-up gear group 2 and impeller spindle 3.Wherein impeller spindle 3 vertical settings and upper end are provided with wind wheel, the lower end of impeller spindle 3 is vertically stretched in the step-up gear group 2 and is linked to each other with step-up gear group 2, evenly be provided with a plurality of generating heads 1 on the outer side elevation of step-up gear group 2, horizontal positioned and the main shaft that is in the generating head 1 on the same horizontal plane link to each other with step-up gear group 2.
The utility model drives a step-up gear group 2 by impeller spindle 3, and each step-up gear group 2 drives a plurality of generating heads 1, and the power of whole generating machine is increased N doubly; By the speedup principle of step-up gear group 2, make single generating head 1 reach the rated speed of expection in addition, thereby whole generating unit rated power is increased.A plurality of generating heads 1 are with mainly containing two advantages with a gear speedup case group 2: the first is by using the speedup principle of step-up gear group 2, play the advantage that makes motor head 1 speedup, it two is the generating of turning round simultaneously of a plurality of generating heads, not only saved material but also reach the self generating amount that improves whole unit equally, the cost cost of whole unit is reduced significantly, thereby the cost cost of whole system is reduced, improved the economic benefit of generator set.
Also brake system can be set in the utility model in addition, when wind speed is excessive when overstepping the extreme limit or system voltage when too high, the whole generating unit all begins brake automatically, guarantees whole unit safety, carries out normal power generation efficiently, stably.
The technology that the utility model does not relate to all can be realized by prior art.
