The integral body of vertical axis aerogenerator with cable wire fixture 7 grapplings by the preceding paragraph central support posts 5 tops of cable wire or wirerope on the ground.
As shown in Figure 4, control system is made up of analog-digital converter 18, computer 19, servocontroller 20, wherein analog-digital converter 18 receptions are from the sensor signal of wind vane 8, carry out data after A and deliver to computer 19, computer 19 sends control signal to the servocontroller 20 (computer described here and control program, analog-digital converter, servocontroller are prior art) that is electrically connected with the angle driving mechanism 2 that facings the wind by program.
Concrete installation process is as follows:
Use bolt that 6 sections 12 meters long central support posts 5 are connected into 72 meters long newels, every section 12 meters long central support posts 5 are the tubular steel structure, and sail leaf supporting disk 3 is packed on the central support posts 5.Several (present embodiment is 4) shaft joints 6 (length is 600mm) are arranged on each sail leaf supporting disk 3, described shaft joint 6 can be around self vertical axis rotation, its inside is the compound thrust bearing that magnetic thrust bearing and radial ball bearing are combined, the frictional force when being intended to reduce rotation.Use bolt, 11.4 meters long, 5 meters wide discrete segmented sail leaf 4 is connected into 4 60 meters long compound sail leaf by shaft joint 6.There is 1 below each compound sail leaf independently as the motors of the angle driving mechanism that facings the wind, in order to regulate the angle that facings the wind of each compound sail leaf at any time.The bottom of bottom one section central support posts 5 is fixed on the pedestal 9 of the reinforced concrete in the Dynamo Room 1 by main bearing 10.Cable wire fixture 7 is equipped with on the top of the one section central support posts 5 in vertically arranged the top, it is provided with cable wire link 18 along all directions, by hang thereon the direct grappling of cable wire on the ground, or link to each other, with the stability and the wind loading rating of reinforcement blower fan with other wind-driven generators.One wind vane 8 is installed above cable wire fixture 7, record wind direction and wind-force with built-in sensor, on the computer 19 of these wind direction wind-force data in analog-digital converter 18 reaches Dynamo Room 1, computer 19 is adjusted the angle that facings the wind of each compound sail leaf by the servocontroller 20 and the angle driving mechanism 2 that facings the wind according to each compound sail leaf and the residing relative position of wind direction, resistance maximum when making it with the wind, the resistance minimum absorbs wind energy to greatest extent in the time of against the wind.When wind-force is too big, for avoiding overload, make sail leaf with the wind suitable, prevent to absorb too much wind energy with the resistance difference of sail leaf against the wind by the angle that adjust to facing the wind.
The present invention is further illustrated below in conjunction with principle.
Because the present invention adopts the compound sail impeller structure of segmented, and several sail leaf supporting disks 3 are arranged in the centre of compound sail leaf, can reduce the moment of flexure of compound sail leaf in wind widely and scratch power.Can obtain bigger sail leaf area with less material in addition; Short sail leaf also is convenient to processing, transportation and is installed.The sail leaf of central support posts 5 corresponding segments also can be assembled into an integral body then by segmentation processing.Adopt structure of the present invention, though the newel of the vertical axis aerogenerator of 1.5MW is also up to 60 meters, because the capital of newel can be with cable wire or wirerope grappling, so newel and ground lightweight widely.Simultaneously because compound sail leaf only vertically centers on the newel setting, so floor space is very little, with 1.5MW is example, if use 60 meters long sail leaf, horizontal axis wind-driven generator takes up an area of about 10,000 square metres in the employing prior art, and adopts the present invention's vertical axis aerogenerator occupation of land only to be 400 square metres.Therefore the present invention's vertical axis aerogenerator is more suitable for being arranged in the wind field in group of planes mode, form net with cable wire on the top of each wind-driven generator newel again, grappling just can improve the utilization ratio of wind field widely and reduce the land expropriation cost of unit generated energy on the ground then.
Wind-driven generator adopts mechanical bearing to reduce the frictional loss method of rotating part in the prior art in order to overcome, cause fault easily and cause problems such as difficult in maintenance, the invention provides a kind of shaft joint 6 and main bearing 10 of compound thrust bearing, the energy loss of rotating part is reduced greatly, reduce the possibility that mechanical part breaks down, saved maintenance cost effectively.
Because vertical axial configuration sail leaf of the present invention, when increasing the output power of wind-driven generator, just must strengthen the width and the height of sail leaf, high-power wind-driven generator is stressed very big simultaneously, must guarantee the intensity of structure, these all make the weight of rotary component increase greatly.Even if use wirerope to anchor to the stability that improves system architecture on the ground at the wind-driven generator top, the weight of whole rotary component also will reach 65 tons, just become vital problem so reduce the frictional loss of the huge rotary component of weight like this in rotary course.The rotary component of horizontal axis wind-driven generator has only blade, and supporting mechanism is all fixed, and powerful vertical axis aerogenerator all can run into this problem.The Nd-Fe-Bo permanent magnet material that utilization of the present invention occurs has in recent years designed a kind of compound thrust-bearing near zero friction especially and has solved this problem.
Consider the vertical axis aerogenerator rotary component around the vertical shaft rotation, what bearing was born is the weight that whole wind machine comprises sail leaf and supporting mechanism, and the main load of bearing is an axial load, and radial load is very little.The present invention utilizes the principle that the magnetic pole same sex is inhaled mutually, the opposite sex is repelled each other, at first compound thrust-bearing is installed on the main bearing 10, it comprises magnetic thrust bearing and is installed in radial ball bearing on the sleeve pipe, referring to Fig. 3-1,3-2, specifically: each arranges that (present embodiment adopts 2 donuts to the even number donut that is made of permanent-magnet material 15, is installed in respectively on the concentric annular boss on the upper and lower chassis of main thrust bearings on main thrust bearings low bottom-disc 101 and main thrust bearings top bottom-disc 102; Specifically can install as follows: concentric annular boss D105, interior concentric annular boss D107 outside on main thrust bearings low bottom-disc 101, establishing, two concentric annular boss diameter differences but etc. width; Concentric annular boss C106, interior concentric annular boss C108 outside on main thrust bearings top bottom-disc 102, establishing, two concentric annular boss diameter differences but etc. width; To be packed on described four concentric annular boss with the corresponding permanent-magnet material 15 of concentric annular boss size again, form the annulus that corresponding in twos 4 permanent magnets that are provided with are formed), the concentric annular boss at relative position place, the upper and lower chassis of main thrust bearings is to wait radius and wide (in the present embodiment, the diameter of concentric annular boss is respectively 1680mm, 1280mm, and width is 100mm; The magnetic material that uses is square Nd-Fe-B permanent magnetic piece, and thickness is 20mm; Each has two diameters above the Nd-Fe-B permanent magnetic piece be the circular hole of 5mm), the Nd-Fe-B permanent magnetic piece is fixed on the concentric annular boss of the upper and lower dish of main thrust bearings by described two circular holes with bolt.Wherein: the polarity of Nd-Fe-B permanent magnetic piece is to arrange like this: the polarity of the Nd-Fe-B permanent magnetic piece on same annulus is identical, the polarity of the Nd-Fe-B permanent magnetic piece of arranging at two annulus on same chassis is opposite, and the same sex of the Nd-Fe-B permanent magnetic piece on the annulus that diameter is identical between the upper and lower chassis of main thrust bearings is relative.Like this when the upper and lower chassis of main thrust bearings that the Nd-Fe-B permanent magnetic piece has been installed closes up relatively, because the effect of magnetic pole has just produced thrust (in the present embodiment, when 10mm, thrust is 32 tons on the upper and lower chassis of main thrust bearings, is about 120 tons when 5mm).Because the remanent magnetism after neodymium iron boron magnetizes much smaller than coercivity, therefore needn't be worried can produce the demagnetization phenomenon under the long-term contrary magnetic stripe spare.But because this thrust is a unstable couple, it can not make system's stable rotation under load, in order to guarantee that thrust acts on the rotating center all the time, the present invention is used a radial ball bearing and stablizes the rotating center on the upper and lower chassis of main thrust bearings, has constituted compound thrust-bearing with magnetic thrust bearing.Yet this radial ball bearing has different usings method with common radial ball bearing, because described magnetic thrust bearing is a kind of elastic system, it can be subjected to displacement with the vertical axial load variations that the wind-force variation causes, small earthquake also can cause the axial displacement of described magnetic thrust bearing.But radial ball bearing is not allow axial displacement, for fear of in this case ball bearing radially being damaged, the present invention has adopted following technical measures: establish a main thrust bearings chassis rotary middle spindle 103 at the central part of main thrust bearings low bottom-disc 101, outside main thrust bearings chassis rotary middle spindle 103, be provided with a sleeve pipe that is slidingly matched 608, radial ball bearing 609 is equipped with in the upper/lower terminal outside of sleeve pipe 608 respectively, and the outer ring of the bearing of radial ball bearing 609 is fixed among the axis hole B104 of main thrust bearings top bottom-disc 102 central parts.Like this, when the upper and lower chassis of main thrust bearings during, only be the axial displacement that produces between sleeve pipe 608 and the described main thrust bearings chassis rotary middle spindle 103 with the variation generation axial displacement of axial load, radial ball bearing 609 is not subjected to any axial force.
