As shown in Figure 1, the present invention includes housing 16, upper and lower settings and all be fixedly mounted on flip sleeve 4 and supporting base 10 in the housing 16, be movably arranged on fork 3 and the slide bar 6 on the flip sleeve 4 and be movably arranged on push rod 9 on the supporting base 10, the center line of housing 16, flip sleeve 4, supporting base 10, fork 3, slide bar 6 and push rod 9 is located on the same line.Wherein, the epimere of fork 3 partly stretches out above flip sleeve 4, and on the epimere of fork 3 part elastic component is installed, elastic component is that vertical direction setting and upper end portion are fixed with mass ball 1, the underpart that is positioned at flip sleeve 4 inherent forks 3 is fixed with the inverted cone platform, the upper diameter of inverted cone platform matches with the diameter of flip sleeve 4, and fork 3 is driven by mass ball 1 and elastic component, and does swing on the two-dimensional directional by the inverted cone platform in flip sleeve 4.Slide bar 6 is arranged on the below of fork 3 by spring seat 7, the upper end portion of slide bar 6 is fixed with the slide bar round platform, be set with slide bar Returnning spring 5 on the slide bar 6 and between slide bar round platform and spring seat 7, slide bar 6 closely contacts with fork 3 under the effect of slide bar Returnning spring 5, be that the upper surface of slide bar round platform and the lower surface of inverted cone platform closely offset, during fork 3 swings, the inverted cone platform presses the slide bar round platform downwards, and slide bar 6 is moved up and down in flip sleeve 4.The epimere of push rod 9 partly stretches out above supporting base 10, the upper end portion of push rod 9 is fixed with the push rod round platform, be set with push rod Returnning spring 8 on the push rod 9 and between push rod round platform and supporting base 10, push rod 9 closely contacts with slide bar 6 under the effect of push rod Returnning spring 8, be that the upper surface of push rod round platform and the lower end surface of slide bar 6 closely offset, when slide bar 6 moved up and down, the lower ends downward of slide bar 6 pressed the push rod round platform, and push rod 9 is moved up and down in supporting base 10.Be positioned on the push rod 9 of supporting base 10 and be fixed with two contact reeds 11 and motion permanent magnetic piece 12, wherein, motion permanent magnetic piece 12 is round table-like and is fixed on the underpart of push rod 9, two contact reeds 11 are symmetrical set above motion permanent magnetic piece 12, the intracavity bottom of supporting base 10 is fixed with fixedly permanent magnets 13 and two fixed contacts 15 that all have conducting plate 14, fixedly permanent magnets 13 is round table-like and corresponding with motion permanent magnetic piece 12 positions, in the fixing arranged outside of permanent magnets 13 annular shoulder is arranged, two fixed contacts 15 all are arranged on the annular shoulder, and two fixed contacts 15 are corresponding respectively with two contact reed 11 positions, the height of annular shoulder is greater than the contact reed 11 on the push rod 9 and the mounting distance between the motion permanent magnetic piece 12, with prevent the present invention when working motion permanent magnets 12 and fixedly permanent magnets 13 be pulled together fully.
In the present embodiment, the upper end port of flip sleeve 4 is the inverted cone port, like this, and when mass ball 1 amplitude of fluctuation is excessive, fork 3 will tilt to be pressed on the conical surface of inverted cone port, thereby has avoided each assembly to cause damage because of mass ball 1 amplitude of fluctuation is excessive.In addition, the radical elasticity of elastic component also can absorb the portion of energy of mass ball 1.The lower end surface diameter of inverted cone port is deviate from flip sleeve 4 when swinging to prevent the inverted cone platform less than the diameter of flip sleeve 4.Elastic component is a swing spring 2.Flip sleeve 4 interts and is fixed on the upper end portion of housing 16.Supporting base 10 is by the inner chamber of screw at housing 16.
As shown in Figure 2; working procedure of the present invention is: at first; the present invention is installed on the pylon of wind-driven generator; and between two conducting plates 14, connect signal sending circuit; signal sending circuit and control system are connected, and control system is advanced the protection of shape undue oscillation according to the signal that receives to wind-driven generator.Like this, when tower oscillation, mass ball 1 is swung on two-dimensional directional with the vibration of pylon, again because the underpart of fork 3 is fixed with the inverted cone platform, and the upper diameter of inverted cone platform matches with the diameter of flip sleeve 4, so mass ball 1 and swing spring 2 can drive fork 3 and do swing on the two-dimensional directional in flip sleeve 4; The inverted cone platform is in swing, driving slide bar 6 moves up and down in flip sleeve 4, slide bar 6 drives push rod 9 again and moves up and down in supporting base 10, contact reed 11 and motion permanent magnetic piece 12 with push rod 9 move up and down constantly away from or near fixedly permanent magnets 13 and conducting plate 14.
Because fixedly the pass apart from S and magnetic force F between permanent magnets 13 and the motion permanent magnetic piece 12 is a non-linear relation, as shown in Figure 3, abscissa S is the distance between fixing permanent magnets 13 and the motion permanent magnetic piece 12, y coordinate F is the magnetic force between fixing permanent magnets 13 and the motion permanent magnetic piece 12, when the swing because of mass ball 1 acts on down pressure on the slide bar round platform, add the fixing magnetic force between the permanent magnets 13 and motion permanent magnetic piece 12 and, less than the elastic force of slide bar Returnning spring 5 and push rod Returnning spring 8 and the time, contact reed 11 does not contact with fixed contact 15.
When motion permanent magnetic piece 12 with when fixedly the distance between the permanent magnets 13 reaches critical distance just; motion permanent magnetic piece 12 and fixedly the magnetic force between the permanent magnets 13 increase considerably suddenly; push rod 9 overcomes the elastic force effect of the elastic force of slide bar Returnning spring 5 and push rod Returnning spring 8 and moves downward; and make two contact reeds 11 and the 15 corresponding adhesives of two fixed contacts; at this moment; be connected two between the conducting plate 14 the signal sending circuit conducting and send control signal, control system is protected wind-driven generator according to this signal.
At two contact reeds 11 and two fixed contacts 15 mutually under the situation of adhesive, when the vibration amplitude of pylon during less than the predefined specified amplitude of the present invention, because the comprehensive function of the elastic force of the elastic force of contact reed 11, the elastic force of slide bar Returnning spring 5 and push rod Returnning spring 8, push rod 9 moves upward, two contact reeds 11 and two fixed contacts 15 are separated, and signal sending circuit disconnects.
The above; it only is preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every according to the technology of the present invention essence to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solution of the present invention.
