Abstract

The utility model discloses a vertical shaft type wind power electric generating device, comprising a main shaft 1, multiple lays of blades 6, blade connecting plates 19, a cross beam 5, a brake disc 13, an electric generator 18. The multiple layers of blades 6 on a rotor are connected with the main shaft 1 through the cross beam 5 and are connected with a lower cross beam 10 mutually from top to bottom to form a cylindrical framework structure, and the lower side of the lower cross beam is provided with a supporting rotary wheel 14. When stressed by wind, the rotary wheel rotates with the main shaft in a synchronized way along the orbit 15 of the concentric circle of the main shaft to drive a blower fan to run. To blower fan devices with high power, multiple layers of rotor wheels and orbits of concentric circles can be provided to ensure that the load of the rotor is distributed more uniformly. Consequently, the utility model is more suitable for being used as a large and medium-sized electric generating device in regions with strong wind.

Description

Vertical shaft wind-driven generator with support rotating wheel

The utility model is a kind of vertical shaft type wind power generation plant.Blower fan runner bottom end rail is provided with the support moving runner, and during wind-engaging, moving runner rotates in main shaft synchronously along the concentric garden of main shaft track, so that the blower fan running.

The present propeller formula wind force device of popularizing though be used already and very suitable to midget plant, lacks of prospects to large-scale electricity generating device.

Series of advantages such as and the vertical shaft type wind energy conversion system has and need not all can be contained in ground to wind apparatus, efficient height, simple in structure, easy to manufacture, generator speed increaser braking device, and Maintenance and Repair are convenient make it more suitable as big-and-middle-sized wind generating unit.But along with design power increases, the wind energy conversion system blowing area also correspondingly increases, and this just must make its height, impeller diameter, blade dimensions increase thereupon.The vertical-shaft fan that has generally all is to be connected with the multiple blade rows rigidity that is vertically mounted on the rotor centerline outer rim by beam arm by bigger rotor main shaft, and the load-bearing tower is arranged in rotor shaft, main shaft tower seat is on the huge basis of burying very deeply, the huge load of overturning will be guaranteed to bear in the basis, because doing the overhang running, rotating shaft also to bear the other wind load of whole sides simultaneously, and to make crossbeam bear leaf weight and running moment, especially big to diameter unit, the very long designing requirement of crossbeam size is very high, and main shaft then requires very high because of bearing whole rotor load intensity.Therefore consume wide variety of materials, influence its development and application.Simultaneously, form strong pneumatic vortex again behind the axle, the tower after wind condition of starting building is degenerated, influenced the operation of blade again because main shaft tower diameter is too big.And to alleviate the burden of main shaft tower, and make the more rational distribution of whole wind wheel load, make it overall construction intensity raising and weight saving, operate steadily, reliably, adopting existing vertical shaft type blower fan is to be difficult to realize.

The purpose of this utility model is to overcome existing vertical shaft type wind power generation plant the problems referred to above just, and a kind of wind generating unit of new structure is provided.It can make the whole wind machine that a plurality of strong points are arranged, thereby overall construction intensity is improved, and Load distribution is even, and the main shaft burden is greatly alleviated.

The purpose of this utility model is achieved in that under original vertical shaft type fan rotor bottom end rail and is equiped with the support moving runner, and most of weight of moving runner bear rotor each layer blade and crossbeam is rotated synchronously along following garden shape track and main shaft.So just significantly reduce the burden of main shaft, the main shaft intended diameter can be reduced greatly, also improved pneumatic operating mode.Being both whole rotor is that cylindrical framework type connects, and has five strong points, has strengthened its stability and reliability greatly.Rotor blade can arrange that each blade is connected with main shaft by connecting plate, crossbeam respectively by concrete diameter by the multiple row multilayer, the continuous up and down formation garden of each row blade of while post framework frame structure, and it is few to make it total rigidity severe deformation.Blade promptly is that the transducer of wind energy power is again the structural member of rotor overall structure frame so up and down, and peritrochanteric has locating column, and the locating column load-bearing is very little, and post is equipped with wind deflector outward, makes it to have double duty.When supporting runner and being provided with the braking device strong wind and the main shaft brake disc act on simultaneously.Because of the support runner has been arranged, therefore not tight simultaneously to the requirement of leaf weight.The easy cost of the selection of blade also can reduce, and the heavier rotary inertia increase that makes whole rotor of blade, and stability and antijamming capability strengthen, and originally holding the wheel accumulation of energy effect of taking off.Also can install multilayer runner and track for large scale wind power machine by concrete condition.Runner and track can be designed to intilted garden shape track, so that integral body is more stable.

The concrete structure of model utility is provided by following examples and accompanying drawing thereof.

Fig. 1 is the overall structure figure of this wind-driven generator.

Fig. 2 is this wind-driven generator schematic top plan view.

Describe the concrete device working condition that the utility model proposes in detail below in conjunction with Fig. 1.

The rotor of this device is by multilayer blade (6), and by blade connecting plate (19), crossbeam (5), same main shaft (1) connect.Each blade links to each other up and down simultaneously and uprightly is connected on the bottom end rail, and whole rotor forms a garden cylindricality frame structure.The bottom end rail downside is provided with and supports moving runner (14), the wheel disc plane is outward-dipping to form outer Eight characters shape with rotor, support runner (14) and be provided with braking device, braking device is a kind of electromagnetic braking brake shoe, and the magnet adhesive makes brake block compress moving runner and tight lock during energising.The garden shape track (15) concentric with main shaft arranged under the moving runner, and garden shape track is an intilted garden arc track with one heart.Whole in addition device also has the spider (3) of going up, following spider (11), upper bearing bracket (2), step (12), location column (7), brake disc (13), speed increaser (16), generator (18), column foot factory building (17).Rotor upper and lower end place has metal (upper to be installed in respectively in upper bearing bracket and the step.Upper bearing bracket (2) is fixed on the spider (3), connects with location column (7) through straining beam (4), and is strained by wirerope (9).Wind deflector (8) is housed to improve Wind Power Utilization on the column, rotor step (12) is fixed on the column foot factory building (17).

During wind-engaging, support runner (14) along the same main shaft of garden shape track (15) (11) run-in synchronism with one heart during the rotor running, rotor main shaft drives generator (18) running through speed increaser (16) again.When wind speed surpassed range of operation, brake disc (13) moved simultaneously with the braking device on the support runner and makes the device braking during strong wind.
