Wind motor
The utility model is a kind of wind-powered machine, belongs to the wind-powered machine manufacturing industry.
According to China Machine Press's version data such as " wind energy plant service manuals " prompting in 92 years, a kind of wind energy engine of the applicant's design, to all can obtain suitable raising at aspects such as power coefficient, Economy than existing similar wind energy conversion system technology, its structural principle is as follows with the literal accompanying drawings:
Split flow contrary wind barrier automatic control speed limit tail vane or tail slurry automatic orientation efficient wind energy machine its Multiblade tail slurry oriented structure such as Fig. 1 in the two guide plates of novel vertical-axis S type or Multiblade double runner engagement type forward and reverse synchronous rotational slide arranged side by side, (it is to be plan view shown in Figure 1 to Fig. 2, because of the breadth reason is set this figure number) shown in, it is by 1 upper cover plate, 2 lower cover plates, 3 supports, 4 left-hand rotation wheel shafts, 5 left-hand rotation wheel seats and wheel arm, 6 left main wheel leaves, 7 left accessory lobes, 8 right wheels, 9 right flow guiding screen baffles, 10 left flow guiding screen baffles, 11 left angular wheel pairs, 12 conventional head and gear-boxes, 13 conventional main pillars, 14 generators, 15 upper right bevel gear pair protective housings, 16 right tail propeller, 17 right guide plate major axis, 18 right guide plate minor axises, 19 left accessory lobes axles, 20 grades of covers, 21 stage clips, 22 adjusting lock nuts, 23 tail slurry axles, 24 hounds, 25 garden cone bearings, 26 linings, 27 tail slurry axle bevel pinions, formations such as 28 runner shaft bevel gear wheels, this structure is for setting wind generating unit; The arrow indication is for setting wind direction among Fig. 2; For simplification view, rotating shaft end should be established and all omit not shown as the bearing class.This structure runner shafts etc. generally can be made by steel pipe two ends welding solid shaft, rotaring wheeling base wheel arm etc. generally can be by combine and assemble such as compression moulding glass fibre reinforced plastics, cast aluminium alloy or steel structure welding to simplify technology, and main wheel leaf, accessory lobes, guide plate generally should be affixed with its reinforcement arm riveted joint or screw by cloth shape glass fibre reinforced plastics, thin aluminum sheet, sheet metal etc.As shown in the figure, two vertical shaft runners are done the forward and reverse work arranged side by side of engagement shape, because it is bevel gear pair interlock engagement separately, cause two runners to rotate synchronously all the time, when the main wheel leaf was in the wind in the radius, accessory lobes and main lobe were adjacent to, and formed the face work done of going for a drive jointly, go to when radius is interior against the wind, cause the accessory lobes disappointing wheel blade resistance against the wind that alleviates of deflection against the wind owing to rotating shaft 19 is in accessory lobes non-stress central position; Two arc deflector cunnings are loaded on up and down in the cover plate arc guide groove, make it be in two runners and overlap center, the place ahead symmetrical position against the wind, (the guide plate inboard is level installing reset tension spring separately up and down, its spring one end can be fixed in centre strut or cover plate up and down, the other end then is fixed in guide plate outer ledge place, do not draw for simplifying this structure of view) it has three kinds of functions: 1, when the wind energy engine proper functioning, can make runner sweep wind-force in the flow area down with the wind and almost all blow to runner leaf and make effective merit with the wind; 2, runner blade is played barrier action against the wind to alleviate wheel blade resistance against the wind; 3, when surpassing rated wind speed, strong wind will force guide plate to overcome inboard tension spring and cause guide plate and slide to both sides, stop that quite a few wind-force can not directly blow to wheel blade face in the work done radius and cause wheel blade and be subjected to barrier action down with the wind and speed limit, and two guide plates separate the center at this moment will have quite a few wind-force to blow to the interior wheel blade face of radius against the wind, cause it and increase against the wind that resistance also can cause the runner speed limit, cover plate (it generally can be made by glass fibre reinforced plastics) can form the better barrier space that facings the wind jointly with guide plate up and down, the less occasion of power can be saved and only get conventional skeleton construction, when wind energy engine power was big, support all need be established to gain in strength in four jiaos of appropriate locations of cover plate up and down; This structure generally should be established tail vane automatic wind facing orientation, but in order fully to obtain utilization ratio of device, get tail slurry device as shown in the figure, can obtain automatic orientation effect down with the wind equally, and can improve the complete machine power gain, when proper functioning, the garden cone bearing only is subjected to tail slurry reaction thrust, bevel gear pair is in reasonable engagement work, during the wind-force hypervelocity, the tail slurry rotating speed increases lift and increases, and the axial top power of its generation will force pressure 1 compression in a short time to cause the increase of bearing element frictional force, (the slurry axle should be got with bearing inner race and be slidingly matched) 28,27 big bevel pinion engaging friction power also will increase, and its acting in conjunction is speed limiting also.Gear pair should be got the suitable rotational speed ratio during practical design, guarantees the unlikely stall of tail slurry best effort, and about slurry should get forward and reverse and " engagement shape " design.
This structure is used for generally should getting the transmission of even-even spur wheel symmetry when occasion such as drawing water, and height, diameter that runner is swept flow area are littler than also getting, to obtain low rotation speed large torque, be used for as occasions such as generatings, then its ratio should be got greatly, to obtain higher rotation speed.In addition, understanding according to the applicant, this structure runner is generally got the S type for best, to reduce equipment cost and dead load as far as possible, certainly this structure generally is applicable to microminiature Wind Power Utilization device, particularly hundreds of watts to thousands of watts of grade wind driven generators etc., will be highly significant, are good though aspects such as material use power ratio generally belong to conventional propeller formula wind energy conversion system, but this structure manufacture process requirement is not high, and its startability, Security, suitable wind is all better, significantly, and the design's compact structure, material, power coefficient is higher, increase and decrease speed design is convenient, and applicability is strong, undoubtedly will have quite desirable operating life.When being any wind speed wind-exposuring area constant be a big defective of this structure, should guarantee sufficiently high rated wind velocity such as support and pylon during practical design, and whole appearance all need be done corrosion protection and handles.The small-power wind energy engine can save accessory lobes runner blade directly is designed to integral structure, or accessory lobes are designed to as conventional automatic speed limit device.
