Abstract
The utility model discloses a small -size wind energy conversion system is to wind damping device, it includes the damping cover, the friction piece, adjust compression spring, spring plate and pretension bolt, damping cover one end to the other end overlaps in proper order and is equipped with the friction piece, adjust compression spring, spring plate and pretension bolt, the one end of friction piece is arranged in outside the damping cover, the other end and the regulation compression spring one end fixed connection of friction piece, adjust the compression spring other end and spring plate fixed connection, pretension bolt and damping cover bolted connection, the one end of pretension bolt extends to the damping and overlaps interiorly and contact with the spring plate extrusion. The utility model has the advantages of, the accuracy that can guarantee the wind energy conversion system has reduced the frequent and quick change of wind wheel to wind the time, avoids the wind energy conversion system because of the change of wind wheel makes the wind energy conversion system take place the vibration, improves wind energy conversion system complete machine job stabilization nature, makes wind energy conversion system output stable.
Description
Technical field:
The utility model relates to a kind of damping device, and particularly a kind of small wind turbine is to wind damping device.
Background technique:
The power equipment of wind energy conversion system to be a kind of with wind the be energy, could obtain maximal wind-energy when the wind wheel of wind energy conversion system is vertical with wind direction, in small wind turbine, generally all adopt empennage to wind to ensure that wind wheel is perpendicular to wind direction.Solid of rotation is one of vitals of small-sized wind power generator, its effect supports to install generator, wind wheel and empennage speed regulating mechanism etc., and ensure that above-mentioned workpiece freely turns round in frame upper end according to the change of respective work characteristics along with wind direction, existing solid of rotation is generally by two dribbling bearings, resisting moment is little, causes wind wheel frequently and fast to rotate with the wind, causes wind energy conversion system complete machine job insecurity, undercapacity, even vibrates.
Model utility content:
The purpose of this utility model be to provide a kind of ensure wind energy conversion system accurate to wind, decrease a kind of small wind turbine that wind wheel frequently and fast changes to wind damping device.
The utility model is implemented by following technological scheme: small wind turbine is to wind damping device, it comprises damping sleeve, friction member, regulate Compress Spring, spring bearer plate and pretension bolt, described damping sleeve one end is arranged with described friction member successively to the other end, described adjustment Compress Spring, described spring bearer plate and described pretension bolt, one end of described friction member is placed in outside described damping sleeve, the other end of described friction member is fixedly connected with described adjustment Compress Spring one end, the described adjustment Compress Spring the other end is fixedly connected with described spring bearer plate, described pretension bolt is connected with described damping sleeve bolt, one end of described pretension bolt to extend in described damping sleeve and extrudes with described spring bearer plate and contacts.
Advantage of the present utility model: the accurate to while wind of wind energy conversion system can be ensured, decrease frequently and fast changing of wind wheel, avoid wind energy conversion system to make because of the variation of wind wheel wind energy conversion system vibrate, improve the stability of wind energy conversion system complete machine work, make wind energy conversion system stable output power.
Accompanying drawing illustrates:
Fig. 1 is scheme of installation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 analyses and observe enlarged diagram.
Damping sleeve 1, friction member 2, regulates Compress Spring 3, pretension bolt 4, spring bearer plate 5, rotating component 6, fixed block 7.
Embodiment:
As shown in Figure 1-2, small wind turbine is to wind damping device, it comprises damping sleeve 1, friction member 2, regulate Compress Spring 3, pretension bolt 4 and spring bearer plate 5, damping sleeve 1 one end is arranged with friction member 2 successively to the other end, regulate Compress Spring 3, spring bearer plate 5 and pretension bolt 4, one end of friction member 2 is placed in outside damping sleeve 1, the other end of friction member 2 is fixedly connected with adjustment Compress Spring 3 one end, Compress Spring 3 the other end is regulated to be fixedly connected with spring bearer plate 5, pretension bolt 4 is connected with damping sleeve 1 bolt, one end of pretension bolt 4 to extend in damping sleeve 1 and extrudes with spring bearer plate 5 and contacts.During use, extrude between the bottom of friction member 2 and the fixed block 7 of solid of rotation and contact, thus make to produce frictional force between the fixed block 7 of friction member 2 and solid of rotation; Pretension bolt 4 is to precession in damping sleeve 1, then extrusion spring pressing plate 5 applies power to adjustment Compress Spring 3, regulates Compress Spring 3 to be compressed, and regulates the compressive force of Compress Spring 3 to increase, friction member 2 can and the fixed block 7 of solid of rotation between frictional force also just increase; Otherwise, then friction member 2 can and the fixed block 7 of solid of rotation between frictional force reduce.
Using method:
Damping device is fixed on the rotating component 6 of solid of rotation, extrudes between the bottom of friction member 2 and the fixed block 7 of solid of rotation and contact, thus make to produce frictional force between the fixed block 7 of friction member 2 and solid of rotation, reduce wind wheel and frequently and fast change; If frictional force is excessive, then pretension bolt 4 is screwed out a part outside damping sleeve 1, regulate Compress Spring 3 compressive force to reduce, the frictional force between the fixed block 7 that can reduce friction member 2 and solid of rotation; If frictional force is too small, then by pretension bolt 4 to a precession part in damping sleeve 1, regulate Compress Spring 3 compressive force to increase, the frictional force between the fixed block 7 that can increase friction member 2 and solid of rotation.Like this by regulating the frictional force between friction member 2 and the fixed block 7 of solid of rotation, make wind wheel both accurately can aim at wind direction, wind wheel can be avoided again frequently to change fast, wind energy conversion system is avoided to make wind energy conversion system vibrate because of the variation of wind wheel, improve the stability of wind energy conversion system complete machine work, make wind energy conversion system stable output power.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
