Technical field
The utility model relates to the technical field of wind power generating set flexible tower vibration damping, refers in particular to a kind of spring active damping regulating connecting rod mechanism of wind power generating set flexible tower.
Background technique
At present, along with wind-power electricity generation is toward marine and Large Copacity blower fan development, the application of Latticed Towers, flexible tower is more and more extensive.But along with the rising of tower height, the vibration problem of pylon is just outstanding all the more.
For tower oscillation problem, existing main two kinds of solutions:
One, increase tower diameter or wall thickness are to improve tower cylinder frequency;
Two, install vibration damping load shedding device in pylon inside additional or keep away resonance control strategy.
Increase diameter and wall thickness must increase cost, keep away resonance control strategy simultaneously.So scheme two is these area research focuses current.But wherein contrast keeps away the generated energy that resonance control strategy can lose part wind power generating set, and present published vibration damping equipment, many employings pendulum structure or vehicle structure, complex structure installation and maintenance inconvenience, difficulty in starting, and general dolly vibration damping structure, determine because moving of car direction is single, just cannot tackle the multi-direction vibration of tower cylinder that wind vector causes after installing, tower oscillation problem still cannot effectively be solved.
Summary of the invention
The purpose of this utility model is that the shortcoming overcoming prior art is with not enough, a kind of spring active damping regulating connecting rod mechanism of simple and reliable for structure, easy for installation, the wind power generating set flexible tower that starts sensitive, quick response is provided, this linkage mechanism can tackle the vibration of pylon different direction, as long as pylon slightly tilts to get final product action vibration damping, realize the multi-direction vibration damping of pylon.
For achieving the above object, technological scheme provided by the utility model is: the spring active damping regulating connecting rod mechanism of wind power generating set flexible tower, include multiple damping regulating connecting rod unit and the link with multiple articulated joint, the tower cylinder that the plurality of damping regulating connecting rod unit is placed in pylon is inner, and it is uniform along the circumference of tower cylinder, the vibration of pylon different direction can be tackled, the damping of self is regulated according to the change at the vibration inclination angle of pylon, and then the bending load that pylon is subject to is cut down, described link is fixedly mounted on the mesa base on tower cylinder top, and be positioned at tower cylinder center, articulated joint quantity on it is consistent with damping regulating connecting rod unit, and a corresponding articulated joint of damping regulating connecting rod unit, the plurality of damping regulating connecting rod unit is movably hinged with the respective hinge head on link respectively, each damping regulating connecting rod unit includes spring, first adjustable damper, second adjustable damper, hinge eyes, sensor, one end of described spring adopts magnet adsorption to be connected with between tower wall obliquely, described magnet adsorption is on tower wall, one end of this spring is movably hinged on magnet, its the other end is movably hinged with unsettled hinge eyes obliquely, one end of described first adjustable damper is movably hinged with the respective hinge head on link obliquely, its the other end is movably hinged with unsettled hinge eyes obliquely, described second adjustable damper is positioned at the below of spring, its one end is movably hinged with unsettled hinge eyes obliquely, its the other end obliquely and be movably articulated in Ta Bishang, described spring, first adjustable damper, second adjustable damper is in same plane, and their rotary centerlines in hinge eyes are same straight line, described sensor is arranged on spring, and the angle for measuring spring, the first adjustable damper, the second adjustable damper changes, and then calculating records damping force size.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
Compare from structural design: than mechanism's vibration damping equipment in the past, the bar linkage structure feature of this spring active damping regulating connecting rod mechanism determines it and has this this advantage of response fast, thus vibration damping is more rapid, this point is for not accomplishing when general pendulum-type and dolly type vibration damping equipment.Again because it is distributed in pylon by multiple damping regulating connecting rod unit, so can cut down the vibration of different direction, and dolly type vibration damping equipment, due to the monotony in moving of car direction, just can only cut down the vibration of a direction after installing.So simple with vibration damping equipment structure compared in the past, and multi-direction vibration damping can be realized.
Compare from performance: because the damping of this spring active damping regulating connecting rod mechanism can be surveyed adjustable, finally can realize carrying out feedback control to damping force, by damping feedback control, the vibration characteristics of control pylon that can be meticulousr.
In sum, this spring active damping regulating connecting rod mechanism effectively can reduce the design load of pylon, thus reduces the weight of pylon, effectively can control again the body vibration of blower fan simultaneously, the performance of comprehensive raising blower fan, be therefore widely used prospect.
