Abstract
The invention relates to a modular combined wind wheel for a wind driven generator. The modular combined wind wheel comprises a vertical wind wheel shaft and radial combined wind blades uniformly distributed on the wind wheel shaft, wherein each radial combined wind blade consists of more than two fan blade units, each fan blade unit consists of fan blade frames and blades, and the blades are connected with the fan blade frames through hinges; two adjacent fan blade frames of each radial combined fan blade are fixedly connected through bolts; the fan blade frames on the inner most layer of each radial combined fan blade are connected with wind wheel shaft bolts; and reinforcing ribs are arranged between every two adjacent radial combined fan blades. The invention has the advantages of simple structure, low cost and convenient transport and mounting, and the volume of the wind wheel can be adjusted at any time according to wind power conditions and the amount of generated electric energy.
Description
Technical field
The present invention relates to a kind of Modular combined wind wheel for wind driven generator, belong to the wind-driven generator parts.
Background technique
Wind-power electricity generation development in recent years rapidly, single-machine capacity is increasing, and is also increasing as the wind wheel of the major impetus parts of wind-power electricity generation.For example the wind generating unit of domestic maximum is promptly by the 2000KW wind-powered electricity generation unit of middle ship heavy industry and German co-design, and totally three blades, weigh 7 tons at long 40 meters of each blade.
Wind generator build the mountain top mostly in or from the city far windy area, these areas are at the end of one's rope mostly, above-mentioned 40 meters long, the blade that weighs 7 tons are transported to the destination, the transportation difficulty is installed also difficulty, has become restriction wind-powered electricity generation unit further to do big bottleneck.
(the patent No.: 02280464.1) that Chinese patent discloses a kind of " wind-powered machine ", above-mentioned patent comprises framework, be installed in the central shaft on the framework, be installed in the fan blade on the central shaft, it is characterized in that: framework install bearing support, lower bearing body up and down respectively, central shaft is installed on the metal (upper body, fan blade is made up of fan blade framework and blade, each fan blade framework is curved, the fan blade frame fixation is installed on the central shaft, blade pass is crossed axle and is installed on the fan blade framework, can overlap successively between each blade on the same fan blade framework.
The shortcoming of above-mentioned patent is the integrated arcuate structure of each fan blade framework, wants to do greatly very difficult, transportation, difficulty too is installed.
Summary of the invention
Technical problem to be solved by this invention provide a kind of simple in structure, cost is low, transportation and Modular combined wind wheel for wind driven generator easy for installation, that can increase or reduce the wind wheel volume by wind conditions and generated energy size at any time.
The technological scheme of the used employing of technical problem solved by the invention:
The present invention includes vertical rotor shaft, be distributed on the radial combined vanes on the described rotor shaft; Each radial combined vanes is made up of the fan blade unit more than 2, and each fan blade unit is made up of fan blade framework and blade, and described blade pass is crossed hinge and is connected with the fan blade framework; Be bolted to connection between adjacent two fan blade frameworks of each radial combined vanes; The fan blade framework of the innermost layer of each radial combined vanes is connected with wind wheel shaft bolts; Be provided with stiffening rib between two adjacent radial combined vanes.
Blade of the present invention is arc surfaced blade or plate shaped blade.
The quantity of radial combined vanes of the present invention is 6-12.
Beneficial effect of the present invention is as follows:
(1) because this wind wheel adopts modular type to assemble, simple in structure, fabricating cost is low, can increase or reduce the size of wind wheel by the size of wind conditions and generated energy at any time; Simple in structure, fabricating cost is low.
(2) convenient transportation, the back of the body of can choosing, horse means of transportation such as are carried on the back and are transported to windy place, mountain top.
(3) install simply, just can install, reduced mounting cost without crane.
(4) because the wind wheel size can easily increase arbitrarily, the torque that equal wind-force produces just increases thereupon, is equivalent to the wind-force of this grade is amplified.
