Description

A kind of dual-motor wind generating unit

Technical field

The utility model relates to a kind of wind generating technology, particularly relates to a kind of press-gathered wind power generating device with two-shipper group.

Background technique

Traditional energy for example coal, oil, rock gas along with a large amount of uses of the mankind are also day by day exhausted, and the environmental pollution of using this class energy to be brought has more and more jeopardized people's living environment, so people begin to pay attention to the R and D of renewable energy sources, for example solar energy, wind energy etc. very early.Wherein be acknowledged as with wind energy again and on development scale and cost of electricity-generating, have maximum progress space simultaneously, so people are not rested all the time in the exploration of technical field of wind power generation, also dropped into simultaneously great amount of manpower and fund, fully integrated use aerodynamics, new material and novel electricity generating device are improved and are utilized.Therefore the installed capacity and the industry size of global wind-power electricity generation all kept high rate of growth in recent years.

In the existing wind generating technology, the wind-driven generator of employing is generally vane type wind power generator, common for example two blades, three blades or four-bladed wind-driven generator.Because such wind-driven generator is to rely on natural wind to promote its blade rotation, be converted into electric energy by mechanical energy again and generate electricity, so in order to obtain abundant wind-force, often need such wind-driven generator is erected on vertical rod, pylon or the tall building, and in order to make its windward side enough big, be by length that increases its blade or running speed and the generating efficiency that width could guarantee it; Moreover, in order to obtain more electric power, the generated energy of unit is obviously not enough, thereby just need cook up wide zone and build generator group, be the wind power plant (windfarm) that we are commonly called as, still, taken a large amount of land areas by the formed wind power plant of large scale wind power machine clustering, but also increased the weight of the costs such as transportation, assembling, maintenance and management of relevant device, so the electric power of its generation is also often because expensive and be difficult to benefit masses.More regrettably, not very abundant or the particularly valuable area of land resources at wind resource, it is then not easy for example to build large-scale wind-force electric field in densely populated metro.

For this reason, the correlative technology field personnel design the wind generating unit of working in can weak wind environment in succession, or the high wind generating unit of raising generating efficiency, as shown in Figure 1, be a kind of wind-collecting wind force power generation unit, its main feature is the wind collecting unit 12 that a horn-like basin body structure is set on Ji Fengta 11, and this wind collecting unit 12 can be realized horizontally rotating on Ji Fengta 11, the basin bottom of this wind collecting unit 12 is equipped with lets out air-valve 13, the basin body bottom of this wind collecting unit 12 is communicated with airduct 14, and this airduct 14 is communicated with the horizontal wind wheel 17 coaxial with the transmission shaft 16 of generator set 15.Though this wind-collecting wind force power generation unit has adopted horn-like basin body structure to enlarge capacity gauge to wind-force as wind collecting unit 12, but, can cause the consumption of wind energy undoubtedly and then have influence on the rotating speed of wind wheel because the wind energy of its collection will be sent to underground horizontal wind wheel 17 by an airduct 14; Secondly, can cooperate wind direction to be rotated for making wind collecting unit 12, this wind-collecting wind force power generation unit has adopted the circuit control technique and then has increased the difficulty and the cost of design; Moreover, only install a wind collecting unit 12 on the collection wind tower 11 and still be difficult to reach the purpose of saving land resources.

The somebody designs another kind of wind-collecting wind force power generation device, as shown in Figure 2, this wind-collecting wind force power generation device mainly is made up of slide rail 21, carriage 22, wind-collection cover 23, fan 24, generator 25, this wind-collection cover 23 is installed on this carriage 22, the afterbody outlet of this wind-collection cover 23 is provided with fan 24, and these carriage 22 pole lower end fixed pulleys 26 are so that it can be mobile on endless glide 21 according to the variation of wind direction.Although this wind-collecting wind force power generation device has also adopted horn-like structure to enlarge capacity gauge to wind-force, but need and drive whole carriage 22 by pulley 26 and slide rail 21 and rotate together because this wind-collection cover 23 cooperates wind directions to be rotated, the flexibility of its rotation is restricted, What is more, when wind-force is more weak, also might not reach the purpose that turns to, and, each wind-collection cover 23 all needs to cooperate a carriage 22 and slide rail 21, because it has huge volume, still fail to reach the purpose of reduction floor space.

A kind of wind cylinder type wind power generating device with wind vane is arranged again, as shown in Figure 3, be made up of wind-drive device 31, runner 32, generator 33 and the steering gear 34 with rotating disk, this wind-drive device 31 is the collecting type air duct of typhon shape; This collecting type air duct below fitting machine body panel 35, this framework platform 35 is for being used for fixing the Steel Support of collecting type air duct; This framework platform 35 is fixed on the rotating disk; The osculum end of this collecting type air duct is equipped with and drives the wind vane 36 that the collecting type air duct rotates.Similarly, this wind cylinder type wind power generating device with wind vane still fails to solve the flexibility problem of wind-drive device rotation, and a framework platform 35 only can be installed a wind-drive device 31 and generator 33, as building the group of wind-driven generator, need take very big land area equally.

So, how high efficiency wind generating unit is provided, make it under low wind friction velocity, have higher generating capacity, and can also should be able to be combined into large-scale power generating group along with the variation adjustment of the wind direction orientation that facings the wind with less power generating modules.Strong, the wide accommodation of generating capacity not only, and can conveniently make, transport, install and reduce cost of investment.

Summary of the invention
