Abstract
The invention discloses a vertical axis wind motor. A girder structure is adopted inside a blade of the vertical axis wind motor, and a skin is arranged outside the girder structure. The girder structure can also be adopted for the main axis of the vertical axis wind motor and even for a wind wheel supporting arm, and the wind motor design with a brand new concept creates a brand-new line for the technology development of the vertical axis wind motor, thereby greatly reducing the cost of the vertical axis wind motor which is more convenient for installation and transportation, and better benefiting the popularization and application of the vertical axis wind motor.
Description
Technical field
The present invention relates to a kind of wind motor, especially relate to a kind of vertical-shaft wind motor.
Background technique
Traditional vertical-shaft wind motor adopts blade, support arm, main shaft to be fixed with one, the structure that pivoting support bearing by root supports (referring to the 78-0577 number report in Sandia laboratory), in this structure, pivoting support bearing is bearing the weight and the aerodynamic load of blade, bear axial force, radial force and moment of flexure simultaneously, this unit is big more, the load that its pivoting support bearing bore is just big more, therefore can be restricted the working life of this pivoting support bearing, increase the maintenance cost of wind motor greatly.In order to reduce the suffered blade gravitational load of root bearing, the hollow core structure of the general employing of existing blade, but in order to bear complicated wind load, the material that is adopted had both needed the rigidity that keeps certain, keep certain intensity again, therefore generally all also have certain thickness, cause the gravity of whole blade significantly not reduce like this.And this blade processing difficulty.
In order to reduce the suffered gravitational load of root bearing, the weight that reduces main shaft self to greatest extent also is included into the consideration category of novel wind motor.Application number is that 200920076471.5 Chinese patent application has disclosed a kind of vertical-shaft wind motor, this vertical-shaft wind motor is provided with bearing between described main shaft and wind wheel, like this, main shaft no longer rotates together with wind wheel, the suffered load of main shaft has had very big improvement, and main shaft can directly fix on the ground.This provides a kind of possibility for alleviating the main shaft own wt.The main shaft of available technology adopting generally still is a hollow cylinder, and the material that is adopted had both needed the rigidity that keeps certain, kept certain intensity again, therefore generally all also has certain thickness, cause the main shaft own wt still very big like this, difficulty is installed, and cost is higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of brand-new vertical-shaft wind motor, it comprises wind wheel, main shaft and generator, wherein said wind wheel comprises blade and support arm, and described blade interior adopts truss structure, and truss structure is outside equipped with covering.
The present invention further technical characterstic is:
Described blade truss structure is one whole or at least by forming more than two sections.
Be provided with vibration damper in the described blade truss structure.
Adopt between described covering and the blade truss structure and removably connect.
Described main shaft adopts truss structure.
Described main shaft truss structure is triangular prism shaped, four prism type or hexagon.
Described main shaft truss structure is one whole or at least by forming more than two sections.
Be provided with vibration damper in the described main shaft truss structure.
The invention has the beneficial effects as follows: because the wind wheel blade and the main shaft of vertical-shaft wind motor all adopt truss structure, therefore when keeping certain rigidity, effectively reduce the weight of blade and main shaft, and be convenient to the transportation installation; Adopt truss structure can also reduce the cost of production of wind wheel blade and main shaft greatly simultaneously, the present invention has broken traditional design concept, realized a kind of brand-new vertical-shaft wind motor, its wind wheel blade, sleeve and main shaft all adopt truss structure, even the wind wheel support arm also can adopt truss structure, the fan design of this brand new ideas, for a kind of brand-new thinking has been started in the technical development of vertical-shaft wind motor, greatly reduce the cost of vertical-shaft wind motor, and install and transport convenient, more help the promotion and application of vertical-shaft wind motor.
Description of drawings
Fig. 1 is the perspective view of one embodiment of the invention;
The scheme of installation of vibration damper in the truss structure that Fig. 2 is.
Embodiment
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is the perspective view of one embodiment of the invention, vertical-shaft wind motor shown in the present embodiment comprises wind wheel 1, main shaft 2 and generator (not shown), wherein said wind wheel 1 comprises blade 101 and support arm 102, the wind wheel blade 101 inner truss structure 101a that adopt, truss structure 101a is outside equipped with covering 101b.Main shaft 2 adopts truss structure 201a, and truss structure also can be provided with covering 201b outward.The truss structure of main shaft described in present embodiment 201a is a hexagon, can also adopt triangular prism shaped or four prism type.In addition, for the ease of make, transportation and lifting, the truss structure of described wind wheel blade 101 and main shaft 2 can also adopt segmented, promptly by two sections, three sections or more multistage be fixed together and form.In the present embodiment, be fixedly connected between described blade covering 101b and the truss structure 101a,, also can adopt between described blade covering 101b and the truss structure 101a to removably connect for the ease of installing.
As shown in Figure 1, the support arm of wind wheel described in the present embodiment 102 also is to adopt this covering truss structure, same principle is that described sleeve equally also can adopt this structure in the disclosed vertical-shaft wind motor of 200920076471.5 Chinese patent application at application number.
In order to reduce load and the destruction that vibration brings unit, can also in the truss structure of described blade 101, main shaft 2 etc., vibration damper 3 be set as shown in Figure 2.The two ends that are vibration damper are connected with latch closure 4 on being fixed on truss structure by wire rope, and latch closure 4 is bolted to connection with truss, avoids destroying truss structure like this, can not impact integrally-built intensity and rigidity.Simultaneously, this Placement can be installed in the arbitrary position of truss, is not subjected to size restrictions, and it is also very easy to dismantle, and safeguards simpler.In truss structure, add vibration damper 3, when truss structure vibrates, can effectively reduce load and destruction that vibration brings.
In addition, because the present invention extensively adopts truss structure, can adopt the beam of different size according to the difference of diverse location load in the structure truss.The highest beam of working strength in main shaft 2, the lower beam of working strength in blade 101.In same parts, also can adopt different beams, promptly big in main shaft 2 root load, adopt the higher beam of intensity, little in main shaft 2 top load, adopt the lower beam of intensity; Bigger in main shaft 2 root truss sizes, less in main shaft 2 top truss sizes.The density of same truss grid also can be adjusted according to the difference of load, and big near the root load of main shaft as support arm 102, the truss grid is closeer, and little near the end load of blade 101, the truss grid is thinner.
Because the present invention extensively adopts truss structure, therefore when keeping certain rigidity, effectively reduce the weight of blade 101 and main shaft 2 etc., and be convenient to the transportation installation; Adopt truss structure can also reduce the cost of production of main shaft 2 and blade 101 etc. greatly simultaneously.In a word, the present invention has broken the design concept of traditional vertical-shaft wind motor, has realized a kind of design concept of brand-new vertical-shaft wind motor, for a kind of brand-new thinking has been started in the technical development of vertical-shaft wind motor.
