Description
Technical field
The utility model relates to a kind of windmill generating equipment, relates in particular to a kind of windmill electric generating apparatus that utilizes elastic element to reduce resistance.
Background technique
Along with the development of World Economics, the consumption of the energy also increases greatly.China's wind resource and waterpower resourses are abundant, but exploitation prospect is wide.But the windmill that uses at present, wind-engaging is larger to, windage, fan blade lifting surface area less, resistance was larger when fan blade forwarded leeward position to, so efficient is not high, and installed and used and was subject to many condition restriction.
The patent No. is that 200920023762.8 utility model patent discloses a kind of efficient direction-regulation-free windmill, it is characterized in that movable fan blades comprises interior fan blade, external wind wheel, interior fan blade and external wind wheel one end are fixed on the arm of force by rotating shaft, the other end is free end, interior fan blade and external wind wheel inboard arrange closed spacing resetting means, and interior fan blade and the external wind wheel outside arrange respectively one and open spacing resetting means.Because this patent is arranged on the fan blade outside with limit stoper, when fan blade is positioned at downwind position, it is very easy that fan blade is subject to the effect closure of limit stoper, but when fan blade is positioned at the contrary wind position, whether fan blade still is in closed state, and blowing area is little, have the effect control limit stoper of other power to make it open fan blade, so this device can reduce in fact the blowing area of fan blade, efficient is lower; In addition, this device can only be applicable under the stable state of wind-force, then folding and the direction of uncontrollable fan blade when wind-force fluctuation occurs or runs into strong wind; And because limit stoper uncontrollable, uncontrollable fan blade closed or open when fan blade leaves downwind position, still can produce very large resistance.
The patent No. is 200810062388.2 patent of invention, array type sea wind, sea wave double-acting electric generating apparatus that a kind of energy that can utilize simultaneously sea wind and wave generates electricity are disclosed, wherein disclose a kind of can reduce leeward push away the leaf resistance be subjected to the stormy waves device, comprise a change, be evenly arranged several umbrellas of opening or drawing in stormy waves in the change and push away leaf, the miner diameter end that umbrella pushes away leaf is fixed in the change, and its bigger diameter end has a series of backguys to be connected in the change; The bigger diameter end inner side surface that described umbrella pushes away leaf fills a circle external magnet, the change of its bigger diameter end contact fills a umbellule that only has skeleton after umbrella pushes away the leaf gathering, fill a circle internal magnet at the umbellule outer side surface, internal magnet is inhaled mutually with the external magnet that umbrella pushes away on the leaf when umbrella pushes away the leaf gathering.But this is subjected to the stormy waves device still can't be in the stability that reduces in the situation of leeward resistance to guarantee windmill work.
The model utility content
The utility model is large to impact for traditional windmill wind-engaging in the prior art, resistance was larger when fan blade forwarded leeward position to, the shortcomings such as efficient is not high, provide a kind of by utilizing elastic element deformation and the interaction of magnetic field different magnetic poles, reduce windmilling drag, improve a kind of windmill electric generating apparatus that utilizes elastic element to reduce resistance of windmill working efficiency.

As preferably, the length when described elastic element deformation does not occur is much smaller than fan blade bigger diameter end radius, and fan blade launches fully during the deformation of elastic element generation maximum flexibility.
As preferably, described fan blade is that alloy umbrella processed pushes away leaf.
When elastic element deformation did not occur, the umbrella shape fan blade drew in; Elasticity original paper generation deformation makes, and the umbrella shape fan blade launches.Fan blade launches fully during the elastic element largest deformation, and it is impaired to prevent that the umbrella shape fan blade from oppositely launching.
As preferably, described generator is with rotating shaft, and described rotating shaft links to each other with the arm of force.Fan blade is subject to the wind-force effect and drives arm of force rotation, drives the engine shaft rotation by the arm of force, and then makes the generator generating.
The described windmill electric generating apparatus that utilizes elastic element to reduce resistance also comprises wind gage and controller.Even measure wind speed by wind gage, and information is passed to controller, windmill is impaired when being controlled two extreme directions of ring magnet and being prevented typhoon by controller.
The utility model by utilizing elastic element elastic strain and the polar character of magnet, realize following beneficial effect:
(1) by the folding of elastic element control fan blade, make windmill be subject to Wind power propelling in the position against the wind, leeward position resistance is less, forms a moment, makes windmill need not to adjust direction, can rotate voluntarily, and improve wind energy utilization;
(2) interaction by magnetic force band and ring magnet, applying one to windmill can attraction force or repulsive force, makes rotating freely of windmill have more stability;
(3) this device is simple in structure, and the energy source clean of generation is renewable, and the protection of environment and the development and utilization of new energy are significant.
