Wind resource is to use many new energy recently, use many a kind of modes to utilize wind-driven generator that wind energy is converted into electric energy exactly to wind resource, relatively more commonly used is in the outdoor blower fan exploitation wind energy of setting up, no matter which kind of wind generating unit all is placed on ground, more than the sea, rely on the wind-power electricity generation of natural wind, this kind mode is subjected to the influence of geographical environment bigger, and wind collecting do not have rule, and collecting energy is put aside and could be used within a certain period of time.
In recent years, the orbit construction development in many cities of China is swift and violent, well-known subway can produce huge wind energy when entering the station and during departures, in subway tunnel, when electric locomotive moves, can produce very big air flows, wind speed is greater than 4 meter per seconds, and subway per tour train number all is regular, and certain interval of time just has train to enter the station, and the wind energy of Chan Shenging also is to be periodic so.Simultaneously, for passenger's safety, and the loss of reduction waiting room air-conditioning, shielded gate all has been installed between track and Waiting Lounge, iron tunnel, old place is the space of a relative closure, has the people just to invent the power generating equipment that a kind of utilization is enclosed in the periodicity wind energy in the subway orbit for this reason.
As a patent No. is a kind of underground railway tunnel wind power generator the Chinese utility model patent " underground railway tunnel wind power generator " of ZL200920071063.0 (notification number is CN201396251Y) has disclosed, and includes wind wheel, speed increaser, one-way element, individual event accumulation of energy buffering synchronizer and multistage generator; This wind-power electricity generation is confidential will be asked wind wheel half will embed wall, and half is arranged on the wall outside, this subway tunnel wind power generator, and complex structure, the manufacture cost height will change tunnel structure and unrealistic, the installation and maintenance inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure and be convenient to the subway tunnel wind power generating set with vertical shaft of installation and maintenance at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of subway tunnel wind power generating set with vertical shaft, include wind-driven generator, transmission shaft and be installed in impeller on the transmission shaft, it is characterized in that: also comprise fixed support and lower margin fixed tray, wherein, the described fixed support of going up directly is fixed on the wall in tunnel, the lower margin fixed tray directly is fixed on the ground in tunnel, the upper end of transmission shaft is installed on the fixed support by bearing support, the lower end of transmission shaft is connected with the rotor of wind-driven generator, and the stator of described wind-driven generator is fixed on the lower margin fixed tray.
Above-mentioned upward fixed support is an A-frame.A-frame consumptive material under the guaranteed prerequisite of steadiness is minimum.
Above-mentioned impeller is made up of many groups vane group, and evenly is provided with at interval along circumference.
Above-mentioned each vane group comprises the blade that cross section is curved, and goes up fixed tray and lower fixed disk; The upper edge of described blade and the outer edge of last fixed tray are fixed, and the alignment of the outer edge of the upper edge of blade and last fixed tray; The lower edge of described blade and the outer edge of lower fixed disk are fixed, and the alignment of the outer edge of the lower edge of blade and lower fixed disk; The described side of fixed tray and lower fixed disk of going up is along fixing with transmission shaft respectively.Leaf cross-section in this vane group structure is curved, therefore the whole blade group is corrugated shape, and the vane group of corrugated shape can better be utilized wind energy, make whole wind power generation device efficiency height, have, the blade in this vane group makes the thickness of whole blade group increase under the fixation of last lower fixed disk again, therefore vane group integral intensity height is not fragile.
Above-mentioned vane group has three groups.Certainly vane group also can be four groups or five groups.
Compared with prior art, advantage of the present utility model is: this wind generating unit is fixed between fixed support and the lower margin fixed tray, can be easily fixed on the wall in tunnel and go up fixed support, the lower margin fixed tray can be easily fixed on the ground in tunnel again, therefore this device has installation and maintenance advantage easily, moreover it is few that this wind generating unit relates to parts, so simple in structure.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, be a preferred embodiment of the present utility model.
A kind of subway tunnel wind power generating set with vertical shaft includes wind-driven generator 1, goes up fixed support 4, lower margin fixed tray 5, transmission shaft 2 and is installed in impeller 3 on the transmission shaft 2, and the energy of rotation of impeller 3 drives transmission shaft 2 rotations.
Impeller 3 is made up of three groups of vane group, and evenly is provided with at interval along circumference.Each vane group comprises the curved blade of cross section 31, and goes up fixed tray 32 and lower fixed disk 33, and the optional ageing-resistant high-intensity hard plastic board of the material of blade 31 is cut out moulding, and technology is simple, and is in light weight, the efficient height; The outer edge of the upper edge of blade 31 and last fixed tray 32 is fixed, and the alignment of the outer edge of the upper edge of blade 31 and last fixed tray 32; The outer edge of the lower edge of blade 31 and lower fixed disk 33 is fixed, and the alignment of the outer edge of the lower edge of blade 31 and lower fixed disk 33; The side of last fixed tray 32 and lower fixed disk 33 is along fixing with transmission shaft 2 respectively.
