Each group of wind wheels are a single whole, the blades of the upper and lower adjacent wind wheels are mutually crossed and installed, and power is output by the rotating shaft. The tower frame has simple and firm structure and good integrity. The diameter of the wind wheel, the height of the tower and the number of the wind wheels can be selected according to requirements. The high-speed wind turbine and the low-speed wind turbine can be made of lift-force type blades or resistance type blades. The machine has the advantages of large effective installation height, strong starting capability and convenient disassembly, assembly and maintenance, and is most suitable for being installed on mountains, fields, seasides and buildings or ships assisted by wind power.
Description
The utility model is a kind of novel wind power utilized device.
Some shortcomings that existing vertical axis windmill exists are: starting force is little or need external force to drag, relative cost was big when setting height(from bottom) increased, and used than long drag-line to make the wind energy conversion system floor space big, and integrity is poor, blade installation makes power output dumb on pivoted housing, and curved vane processing is than difficulty etc.
The tower wind energy conversion system of vertical shaft has overcome the above-mentioned shortcoming of existing vertical axis windmill, and its structure is a tower, is respectively taken turns the movable joint axle (4) of between centers by pylon (1), main air wheel (2), speed governing wind wheel (3) and connection and forms.
Introduce the utility model in conjunction with the accompanying drawings in detail:
Fig. 1: be schematic representation of the present utility model.Fig. 2: the schematic representation of pylon.Fig. 3: the schematic representation of main air wheel.Fig. 4: the schematic representation of speed governing wind wheel.Fig. 5: the schematic representation of movable joint axle.
Pylon (1): as (Fig. 2), form by pylon pillar (5), crossbeam (6), underframe (7), drag-line (8), lacing wire (9) etc.Pylon pillar (5) upper end and the middle part is welded with drag-line ring (10), the bottom is welded with bloom-base (11), and according to the total number of rotor shaft and length be welded with beam seat (12), underframe (7) can be selected size and height as required, be welded with bearing support (13) in the middle of each crossbeam (6), crossbeam (6) two ends are welded with jointing plate (14), also are welded with drag-line ring (10) on each angle of underframe.Pylon pillar (5), crossbeam (6), underframe (7), lacing wire (9) etc. connect with bolt, connect by drag-line (8) at last, and with adjusting bolt (15) tensioning.
Main air wheel (2): as (Fig. 3), form by main air wheel shaft (16), primary blades (17), pull bar (18).Main air wheel shaft (16) upper end is splined shaft (19), and the lower end is spline housing (20), goes up the direct and bearing cooperation in upper end of a main air wheel shaft of joint (16) most, without splined shaft (19).The bottom of main air wheel shaft (16) splined shaft (19) is welded with jointing plate (21), and lower end and pull bar (18) are welded together.Primary blades (17) becomes 20-25 ° of angle to install with main air wheel shaft (16), primary blades (17) can be 1 to a plurality of, and the utility model suggestion is used 2.
Speed governing wind wheel (3): as (Fig. 4), by speed governing rotor shaft (22), speed governing blade (23), upper connecting rod (24), lower link (25) is formed.Speed governing rotor shaft (22) upper end is splined shaft (19), the direct and bearing cooperation in lower end.Upper connecting rod (24) has axle sleeve (26) at an end that connects with speed governing blade (23), and lower link (25) is welded with axle (27) at an end that connects with speed governing blade (23).Speed governing blade (23) upper end has eccentric shaft (28), lower end to have eccentric bushing (29) respectively and axle sleeve (26), and axle (27) cooperates.Steel ball (30) is housed in the eccentric bushing (29), torque spring (31) is housed outward, torque spring (31) also is equipped with in axle sleeve (26) outside.Last lower link inboard is welded with spacing gib (32), speed governing blade (23) and the parallel installation of speed governing rotor shaft (22), as when using more piece speed governing wind wheel (3), except that the lower end of a bottom joint speed governing rotor shaft (22) and bearing directly cooperated, the lower end of other each speed governing rotor shafts (22) also was spline housing (20).
Movable joint axle (4): as (Fig. 5), be the connected element between each rotor shaft, there is splined shaft (34) outside of movable joint axle (4) one ends, screw thread (35), bearing footpath (36), bearing retaining (37).The other end is spline housing (38), has put limit pin hole (39).
The utility model is shown in (Fig. 1): the upper end of main air wheel shaft (16) is assemblied in pylon (1) topmost in the bearing support (13) in the middle of the crossbeam (6), and the lower end of speed governing rotor shaft (22) is assemblied in pylon (1) bottom in the bearing support (13) in the middle of the crossbeam (6).Each end of other each main air wheel shaft (16) and speed governing rotor shaft (22) all is together in series through movable joint axle (4), and movable joint axle (4) is installed in the middle bearing support (13) of corresponding crossbeam (6).Blade (17) or (23) by the neighbouring wind wheel of the control of the splined shaft (34) on the movable joint axle (4) are mutually 90 °.Spline housing (38) mouth down of movable joint axle (4) deposits in to prevent rainwater, dust.All main air wheel shaft (16) and speed governing rotor shafts (22) that spline housing (20) is arranged, when being connected in series with the movable joint axle, spline housing all is placed with steel ball in (20).
When wind-force affacted on the blade, because blade is many groups, installations that cross one another of each wind wheel must have partial blade to obtain the lift maximum, and V-type is installed and made the suffered torsion enhancing of rotor shaft again, and wind energy conversion system can start smoothly.Working in starting back all blade, rotates lift and strengthen, and makes the very fast accelerated service of wind energy conversion system, drives required machine work.When wind speed surpasses the wind energy conversion system rated wind speed; the wind energy conversion system faster rotational speed; the speed governing wind wheel blade overcomes spring under action of centrifugal force anti-torsion outwards opens; the wind energy conversion system resistance of air is strengthened; rotating speed descends; otherwise the speed governing blade all closes, and rotate lift and primary blades promote the rotor shaft running together, reaches the purpose of speed governing and protection wind energy conversion system.
Main feature of the present utility model is: adopt firm pylon structure, organize wind wheel more, wherein be provided with the speed governing wind wheel, the blade of neighbouring wind wheel intersects mutually, connect with the movable joint axle between each rotor shaft of series connection, and be placed with steel ball, can adjust the nonconcentricity of each between centers trace automatically.Thereby wind energy conversion system fortune is passed flexibly, enough starting torsion is arranged, increased effective setting height(from bottom), reduced cost, Yin Lasuo is fixed on the underframe, makes the wind energy conversion system good integrity, and floor space is little.Blade installation makes power output flexible in rotating shaft, and blade has no curvature and torsional angle, is convenient to processing.
The tower wind energy conversion system of vertical shaft is easy to manufacture, and it is wide to draw materials, and pylon can be used various steel, and blade can use concrete pedestal can replace underframe with timber and sheet metal.Can select rotor diameter as required, pylon height and wind wheel number.Can select lift force blade or resistance blade for use, make high-speed type or low speed type wind energy conversion system, between this arbor position limit pin be arranged, folding is adorned easy to maintenancely, is suitable for being installed on the mountain, on field, seashore and building or the ship with the wind-force navaid.
