Energy can be converted into thermal energy by electromagnetic eddy device.However, other damping members known in the art can also be used for this
In the damper 100 of utility model.
As shown in Figure 3 and Figure 6, the first end of damping member 140 may be connected to tower 1000 inner wall and can be along any
Direction is swung.The second end of damping member 140 may be connected to sunpender 120 (as shown in Figure 3).Since damping member 140 being capable of edge
Any direction is swung, therefore damping member 140 can be swung with the swing of sunpender 120.When the second end of damping member 140 connects
When being connected to sunpender 120, a damping member 140 can be only connected on sunpender 120.In addition, it may also connect on sunpender 120 two few
Damping member 140, damping member 140 can vertically offset one from another arrangement on sunpender 120, to prevent damping member 140
Interfere and cause sunpender 120 to swing.Shown in Fig. 6 and connect the cloth that vertically offsets one from another on sunpender 120
The situation for two damping members 140 put, two damping members 140 may be disposed so that in predetermined angular (for example, 90 °).
In addition, the second end of damping member 140 can also be fixed to mass block 130, so as to the swing of mass block 130 and
Swing.When connecting at least two damping members 140 on mass block 130, damping member 140 can be on mass block 130 along vertical
Direction offsets one from another arrangement.
Embodiment according to the present utility model, damper 100 may include frequency modulation device 150.Fig. 7 is the tune shown in Fig. 3
The top view of the arrangement of frequency device.As shown in Figure 3 and Figure 7, frequency modulation device 150 may include elastic component 151 and be fixed to
The frequency modulation platform 152 of the inner wall of tower 1000.The upper end of elastic component 151 may be connected to the lower surface of annulus mass block 130, bullet
The lower end of property component 151 may be connected to frequency modulation platform 152.
The example of 19 elastic components 151, but the utility model not limited to this, the number of elastic component 151 are shown in Fig. 7
Amount can increase or reduce, to adjust the frequency of damper 100.
Specifically, the frequency of damper 100 is related with the length of sunpender 120, but still can pass through regulation elasticity component 151
Quantity and/or pretightning force the frequency of damper 100 is finely adjusted.For example, when by the quantity of elastic component 151 and/
Or pretightning force so that when elastic component 151 increases the total pulling force of annulus mass block 130, the frequency of damper 100 can be also presented
The trend of increase.
Therefore, embodiment according to the present utility model, by set frequency modulation device 150 come the frequency to damper 100 into
Row fine setting, can solve the problems, such as that the frequency of the actual frequency of the tower and damper occurred in the prior art is unmatched.
Embodiment according to the present utility model, damper 100 may also include check device 160.Fig. 8 is shown according to this reality
With the top view of the check device in new damper, Fig. 9 is the sunpender edge shown in damper according to the present utility model
The schematic diagram of the amplitude of fluctuation of all directions, Figure 10 are the signals for the swing process for showing damper according to the present utility model
Figure.
As shown in figures 3 and 8, check device 160 may include：Non-return platform 161, the inner wall fixed to tower 1000, only
Return platform 161 and have and be used to make the first through hole 162 that sunpender 120 passes through, first through hole 162 and the cat ladder 3 in tower 1000 and
Cable 2 is spaced apart, and the inner wall of first through hole 162 is provided with padded coaming；Check disk 163, in the position corresponding to first through hole 162
The periphery for being arranged around sunpender 120 is put, and the periphery of check disk 163 is provided with padded coaming.Non-return platform 161 can also have
Make the second through hole (not shown) that the cat ladder 3 in tower 1000 and cable 2 pass through.
Check device 160 can be used for carrying out damper 100 when the amplitude of oscillation of damper 100 is excessive spacing.Specifically,
When the amplitude of oscillation of sunpender 120 is excessive, sunpender 120 and the mass block 130 swung with sunpender 120 may collide cat ladder 3, line
The inner wall of cable 2 and tower 1000.According to the utility model, when the amplitude of oscillation of sunpender 120 is excessive, set along the periphery of sunpender 120
The padded coaming of check disk 163 can be contacted with the padded coaming of the inner wall of the first through hole 162 of non-return platform 161 so that anti-
Only due to the amplitude of oscillation of sunpender 120 is excessive and caused by collision.
For example, showing the position-limiting action by check device 160 in Fig. 9, check disk 163 is limited by non-return platform 161
The schematic diagram of position.By the way that check disk 163 is limited in non-return platform 161, mass block 130 can be in the not inner wall with tower 1000
And realize the maximum amplitude of oscillation while cable 2 and the collision of cat ladder 3, as shown in Figure 10.
It should be understood that the damper and cat ladder in tower are equidistant relatively near, therefore need in some cases to damping
Device carries out locking (that is, preventing damper from swinging), to ensure the safety of operating personnel.Further, since damper needs
Factory is installed in tower, and is transported to scene and lifted together with tower, this process is also required to damper and is in locking
State, meanwhile, damper is also required to be in lockup state in later maintenance, maintenance.
Therefore, the damper 100 of embodiment according to the present utility model, can when needing to carry out locking to damper 100
Blocking element is applied to damper 100.Figure 11 is the blocking element 170 shown in damper 100 according to the present utility model
Schematic diagram.
As shown in figure 11, connection lock is respectively arranged in the position to correspond to each other of check disk 163 and non-return platform 161
The only connecting hole (not shown) at the both ends of component 170., can be by blocking element 170 when needing to carry out locking to damper 100
Both ends are connected respectively to the connecting hole of check disk 163 and non-return platform 161, by prevent check disk 163 and non-return platform 161 it
Between relative motion occur prevent the damper 100 from swinging.
Illustrate the principle of the utility model by taking sunpender is connected to hanging beam as an example above, but sunpender can by rope Lai
Instead of.
As described above, embodiment according to the present utility model, carries out the frequency of damper by setting frequency modulation device
Fine setting, can solve the problems, such as that the frequency of the actual frequency of the tower and damper occurred in the prior art is unmatched.
In addition, embodiment according to the present utility model, by setting check device, can better control over sunpender and annular matter
The amplitude of fluctuation of gauge block, makes it not collide with tower inner wall, cable and cat ladder.
Although having show and described some embodiments of the utility model, it will be understood by those skilled in the art that
, can be to this in the case of the principle and spirit that do not depart from the utility model that its scope is limited by claim and its equivalent
