Abstract
The utility model provides a windmill capable of changing the natural wind energy into the rotating mechanical energy, comprising a main bracket, a transverse member and windmill blades, etc. wherein, the main bracket is arranged perpendicular to the horizontal ground, the transverse member is fixed perpendicular on the upper part of the main bracket, intercommunicating shafts arranged on the left side and the right side of the main bracket are respectively provided with the windmill blades which are of the same structures and rotate around the intercommunicating shafts in a direction of deviating from intercommunicating shafts by ninety degrees, the left intercommunicating shaft and the right intercommunicating shaft are independent, a connecting gimbal capable of making the left windmill blade and the right windmill blade to overturn in a linkage way, and the lower part of the main bracket is provided with a power take-off wheel. With large wind area and no need of wind directional tracking, the utility model achieves the output with low rotate speed and great moment at a lower wind speed.
Description
The utility model is a kind of mechanical device that natural wind energy is converted into rotating mechanical energy.
At present, the most familiar windmill structure of people is as the fan blade of electric fan, because the area of effect is little, so the power of output is little, and will have the wind direction tracking controlling mechanism, thereby makes the universal Application and Development of natural wind energy utilization receive certain restriction.
It is big that the purpose of this utility model will design a kind of blowing area exactly, do not need the big tree type windmill of wind direction tracking device, improves wind energy utilization.
The utility model is to realize like this.Windmill is by master bracket, transverse arm, compositions such as fan blade, master bracket is installed perpendicular to the level ground, be fixed by the suspension cable on ground supports bearing and the middle part bearing, transverse arm is vertically fixed on master bracket top, the transverse arm both sides have bearing bracket respectively, connection shaft is by be contained in transverse arm on parallel with transverse arm of bearing and bearing bracket, the fan blade of a structure equidirectional around connection shaft deviation 90 degree respectively is housed on the connection shaft of the master bracket left and right sides, the block that makes fan blade and connection shaft 90 degree rotations is housed on the bearing bracket, left and right sides connection shaft is independent mutually, the connection universal joint that can make left and right sides fan blade interlock upset is equipped with in the centre, and power output wheel is equipped with in the master bracket bottom.Fan blade is a frame structure, form by framework and the metal or the fabric fan blade that are fixed on the framework, fan blade when the vertical position area above its connection shaft less than the area below the connection shaft, on the fan blade of connection shaft top the auxiliary fan blade that can unidirectionally open is arranged, an auxiliary fan blade of upset that forms an angle and turned on one's side by master bracket one with fan blade is arranged on the fan blade of connection shaft below.The suspension cable that increases the transverse arm rigidity is housed between master bracket and the transverse arm.Damping spring is equipped with in rotary block and fan blade framework contacting point.Like this, the horizontal wind-force of any direction, the capital makes the fan blade of central shaft one side change into horizontal plane, the fan blade of opposite side changes into vertical surface, formed the stress surface product moment on windmill central shaft both sides, be worth moment of rotation thereby produced the discrepancy in elevation, make windmill rotate the output rotating mechanical energy around center master bracket axle horizontal.Windmill can make two fan blades, also can make four fan blades, also can make multi-layer structure, becomes huge windmill, has realized the big moment of the slow-speed of revolution, the application area and the suitable environment of expansion windmill.
The utility model is compared with existing windmill, and blowing area strengthens, and does not need wind direction tracking, can realize the big moment output of the slow-speed of revolution under less wind speed.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is blade structure schematic representation of the present utility model.
Accompanying drawing 3 is blade structure side diagrammatic sketch of the present utility model.
Windmill master bracket axle 2, transverse arm 8 all is welded to form with steel pipe, master bracket axle 2 is installed perpendicular to the level ground, be fixed by the suspension cable 3 on ground supports bearing 19 and the middle part bearing 4, transverse arm 8 is vertically fixed on master bracket 2 tops, transverse arm 8 both sides have bearing bracket 7 respectively, 9,14,15, connection shaft 5,16 by bearing and bearing bracket 7,9,14,15 with transverse arm 8 parallel being contained on the transverse arm 8, the connection shaft 5 of master bracket 2 left and right sides, the fan blade 18 of a structure equidirectional around connection shaft deviation 90 degree respectively is housed on 16, be equipped with on the bearing bracket and make the block 21 of fan blade around connection shaft 90 degree rotations, left and right sides connection shaft 5,16 is independent mutually, the connection universal joint 11 that can make left and right sides fan blade interlock upset is equipped with in the centre, 12, power output wheel 1 is equipped with in master bracket 2 bottoms.Fan blade 18 is a frame structure, form by framework and the metal or the fabric fan blade that are fixed on the framework, fan blade 18 when the vertical position area above its connection shaft 16 less than the area below the connection shaft 16, the auxiliary fan blade 13 that can unidirectionally open is arranged on the fan blade of connection shaft 16 tops, an auxiliary fan blade 17,6 of upset that forms an angle and turned on one's side by master bracket 2 with fan blade 18 is arranged on the fan blade of connection shaft 16 belows.The suspension cable 10 that increases the transverse arm rigidity is housed between master bracket 2 and the transverse arm 8.Rotary block 21 is equipped with damping spring 20 with fan blade framework contacting point.Like this, the horizontal wind-force of any direction, the capital makes the fan blade of master bracket 2 one sides change into horizontal plane, the fan blade of opposite side changes into vertical surface, formed the stress surface product moment on windmill master bracket axle both sides, be worth moment of rotation thereby produced the discrepancy in elevation, make windmill rotate the output rotating mechanical energy around center master bracket axle horizontal.Windmill can make two fan blades, also can make four fan blades, also can make multi-layer structure, becomes huge windmill, has realized the big moment of the slow-speed of revolution, has expanded the application area and the suitable environment of windmill.
