Abstract

An air operated machine vane in the shape of a composite vane consists of a primary vane and a plurality of secondary vanes. The primary vane consists of a rectangular frame, each secondary vane is in small door shape, the secondary vanes are arrayed inside the frame of the primary vane, the upper end and the lower end of each secondary vane are respectively hinged with an upper edge frame and a lower edge frame of the primary vane via pivots located outside the secondary vanes, the inner side of each secondary vane is correspondingly equipped with a stopper, and the stoppers are fixedly connected to the upper edge frame or the lower edge frame of the primary vane. The air operated machine vane in the shape of a composite vane is simple in structure, and can be adaptive to wind directions, thereby sufficiently utilizing wind energy. Further, the air operated machine vane is high in output power, and can also be mounted and used in places with unstable wind directions.

Description

The leaf air operated machine blade of primary and secondary

Technical field

The utility model relates to air operated machine, particularly the blade of air operated machine.

Background technique

Air operated machine is a kind of device that wind energy is converted to mechanical energy, air operated machine produces power, existing air operated machine blade by the blade capturing wind energy, the overwhelming majority is a propeller type, resistance to wind is less, and the waste wind resource: because always there is individual angle on the blade face of propeller blade with wind direction, wind direction can not be perpendicular to the blade face, distinguished and admirablely always brush past with the blade face, the rotation of promotion blade, the energy density of wind energy is original just very little, so just littler to the thrust of wind energy conversion system.

The model utility content

For addressing the above problem, the purpose of this utility model provides the leaf air operated machine blade of a kind of primary and secondary, and it is simple in structure, can adapt to wind direction automatically, thereby can make full use of wind energy, and output power is big, in the unsettled place of wind direction, also can install and use.

For achieving the above object, the utility model is by the following technical solutions:

The leaf air operated machine blade of a kind of primary and secondary, constitute by female leaf and a plurality of cotyledon, female leaf is made of the framework of rectangle, each cotyledon is the wicket shape, each cotyledon is arranged in the framework of female leaf, and the top and bottom of each cotyledon are hinged by the upper frame and the lower frame of pivot and female leaf respectively, and described pivot is positioned at the outside of cotyledon, inboard at each cotyledon is provided with block accordingly, and block is fixed on the upper frame or lower frame of female leaf.Described cotyledon is made up of doorframe and door-plate.

The utility model has following positive beneficial effect:

Blade of the present utility model is made up of female leaf and cotyledon, cotyledon can female relatively Ye Kaiqi or is closed, blade is installed on the air operated machine main shaft symmetrically, cotyledon on the blade can only be opened in the same direction, this has just guaranteed no matter wind from which direction comes, have at least a blade to facing the wind on the air operated machine, have a blade at least with the wind, the cotyledon on the windward blades is closed, and accepts the thrust of wind, cotyledon on the blade is opened with the wind, wind can see through, so the windward side is greater than face with the wind, and the windward side forms moment of torsion with the pressure difference of face with the wind, the main shaft of air operated machine rotates under torsional interaction, outputting power.

Embodiment

Number in the figure

1 blade, 2 female leaf 3 cotyledons 4 pivots

5 upper frames, 6 pivots, 7 lower frames, 8 main shafts

9 bearing supports, 10 blocks, 11 doorframes, 12 door-plates

Please refer to Fig. 1, Fig. 2, the utility model is the leaf air operated machine blade 1 of a kind of primary and secondary, constitute by female leaf 2 and a plurality of cotyledon 3, female leaf 2 is made of the framework of rectangle, each cotyledon 3 is the wicket shape, each cotyledon 3 is arranged in the framework of female leaf 2, and the upper end of each cotyledon 3 is hinged in the upper frame 5 of female leaf by pivot 4.

The lower end of each cotyledon 3 is hinged in the lower frame 7 of female leaf 2 by pivot 6.Inboard at each cotyledon 3 is provided with block 10 accordingly, and each block 10 is all affixed with the upper frame 5 of female leaf 2.Block 10 also can be affixed with the lower frame 7 of female leaf 2.The inboard of cotyledon 3 is meant that side near air operated machine main shaft 8.

Blade 1 is connected with air operated machine main shaft 8 perpendicular to ground, and air operated machine main shaft 8 is by bearing support 9 supportings, and the lower end of air operated machine main shaft 8 is by the outside outputting power of driving mechanism, and driving mechanism can be a gear mechanism, chain-wheel mechanism etc.

Pivot 4, pivot 6 are positioned at the outside of cotyledon 3, and the outside of cotyledon 3 is meant that side away from air operated machine main shaft 8.

Cotyledon 3 can be made up of doorframe 11 and door-plate 12.Pivot 4, pivot 6 all are fixed on the doorframe 11, and doorframe 11 can be made of metal, and door-plate 12 can be made by canvas or glass epoxy or resin plate.

Because the barrier effect of block 10, the cotyledon 3 on each blade 1 can only be opened toward same direction.Please refer to Fig. 3, false wind is to shown in the arrow among Fig. 3, and the blade 1 that then is positioned at the top is opened with the cotyledon 3 on the blade 1 that is positioned at the right side, and the cotyledon 3 on the blade 1 below being positioned at and the blade 1 in left side is then closed.

Please refer to Fig. 4, false wind is to shown in the arrow among Fig. 4, and the cotyledon 3 that then is positioned on the blade 1 on right side is opened, and the cotyledon 3 that is positioned on the blade 1 of the blade 1 in blade 1, left side of below and top is then closed.

Because blade 1 is being installed on the air operated machine main shaft 8 of symmetry, so, no matter wind direction is how, always have at least a cotyledon 3 on the blade 1 to close down with the wind, and have at least a cotyledon 3 on the blade 1 to open with the wind, so promoting blade 1, wind rotates around air operated machine main shaft 8, when blade 1 forwards to when vertical with wind direction, wind is to its thrust maximum, and air operated machine has wind just to change like this, strong wind changes soon, little wind slow-speed.
