DESCRIPTION Handling tool for a slosh damper disc Technical Field The present disclosure relates to a tool for handling a slosh damper disc. Particularly, but not exclusively, the above- mentioned tool may be use for handling a slosh damper disc during manufacturing and/or maintenance of a wind turbine. Art Background In civil engineering constructions it is known to use harmon- ic absorber or seismic dampers, in order to reduce the ampli- tude of mechanical vibrations, for example caused by the wind or by earthquakes. Their application can prevent discomfort, damage, or outright structural failure. In particular, such dampers may have the form of slosh damper discs, i.e. thin hollow discs having a diameter much greater than the thick- ness filled with a liquid, for example water. Slosh damper discs may be made of a plastic material. The movement of the liquid inside the slosh damper discs provides the desired damping effect.
Slosh damper discs may be used inside the structure of wind turbine, for example inside the tower or the nacelle. The di- ameter and weight of a slosh damper disc may be respectively grater than 2 m and 80 kg, thus preventing the possibility to be handled manually. Therefore, there is a need to provide a tool for conveniently handling a slosh damper disc during manufacturing and/or maintenance of a structure on which the slosh damper disc is to be applied, for example a wind turbine.
DK 2021 70173 A1 2 Summary This need may be met by the subject matter according to the independent claim.
Advantageous embodiments of the present invention are described by the dependent claims.
According to one embodiment, it is provided a handling tool for a slosh damper disc.
The handling tool includes at least a first arm, a second arm and a third arm, each first, second and third arm including a respective clamp at a respective free end for fixing a border of the slosh damper disc to the handling tool, the second arm being inclined with respect to the first arm of a first angle comprised between 45 deg and 135 deg, the third arm being inclined with respect to the first arm of a second angle comprised between 45 deg and 135 deg.
In particular, one or both of the both first angle and the second angle may measure 90 deg.
Such handling tool provide a convenient interface between a slosh damper disc to which the arms of the handling tool are to be clamped and a handling device, for example a crane, which may be used to handle the slosh damper disc.
The han- dling device may be conveniently and stably attached to the handling tool, for example by means of ropes or chains.
This assures that a slosh damper disc attached to the handling tool may be conveniently handled.
At least one of said first, second and third arm may be a telescopic arm, in order to facilitate the coupling between the slosh damper disc and the handling tool.
A central structure may be provided from which each first, second and third arm extends between the central structure and the respective free end at which the respective clamp is provided.
The three arms may lie on a common plane and ex- tends radially from the central structure.
DK 2021 70173 A1 3 The handling tool may comprise more than three arms, for ex- ample four arms disposed along two perpendicular directions. The aspects defined above and further aspects of the present disclosure are apparent from the examples of embodiment to be described hereinafter and are explained with reference to the examples of embodiment. The disclosure will be described in more detail hereinafter with reference to examples of embodi- ment but to which the invention is not limited.
Brief Description of the Drawing Figure 1 shows a schematic section of a wind turbine in- cluding a plurality of dampers.
Figure 2 shows a more detailed of the wind turbine of fig- ure 1. Figure 3 shows a prospective view of one damper coupled to a handling tool according to the present disclo- sure. Figure 4 shows an axonometric view of the handling tool of figure 3.
Figure 5 shows a frontal view of the handling tool of fig- ure 3. Detailed Description Figure 1 shows a wind turbine 1 according to the invention. The wind turbine 1 comprises a tower 2, which is mounted on a non-depicted foundation and extends along a vertical axis 7. A nacelle 3 is arranged on top of the tower 2. The wind tur- bine 1 further comprises a wind rotor 5 having at least one blade 4 (in the embodiment of Figure 1, the wind rotor com- prises three blades 4, of which only two blades 4 are visi- ble). The wind rotor 5 is rotatable around a rotational axis
DK 2021 70173 A1 4 Y. The blades 4 extend substantially radially with respect to the rotational axis Y. In general, when not differently spec- ified, the terms axial, radial and circumferential in the following are made with reference to the rotational axis Y.
The wind turbine 1 comprises an electric generator 11, in- cluding a stator 20 and a rotor 30. The rotor 30 is rotatable with respect to the stator 20 about the rotational axis Y. The wind rotor 5 is rotationally coupled with the electric generator 11 either directly (direct drive electric genera- tor) or by means of a rotatable main shaft 9 and/or through a gear box (not shown in Figure 1). A schematically depicted bearing assembly 8 is provided in order to hold in place the main shaft 9 and the rotor 5. The rotatable main shaft 9 ex- tends along the rotational axis Y. The wind turbine 1 com- prises a plurality of dampers 50 (six dampers 50 in the em- bodiment shown in figure 1) inside the tower 2 for reducing the amplitude of mechanical vibrations, for example caused by the wind. According to other embodiments, any other number of dampers 50 may be provided inside the tower 2. According to other embodiment dampers may be provided additionally or al- ternatively in other components of the wind turbine, for ex- ample inside the nacelle 3.
Figure 2 shows a partial view of the interior space of the tower 2, where three dampers 50 distributed along the verti- cal axis Z are shown in more details. Each damper 50 compris- es a plurality of slosh damper disc 51 stacked along the ver- tical axis Z. Fach slosh damper disc 51 is a plastic hollow disc having a diameter much greater than its thickness filled with a liquid, for example water. The diameter of each slosh damper disc 51 may vary between 1,4 and 2,5 m or more. The movement of the liquid inside the slosh damper discs provides the desired damping effect. The weight of a slosh damper disc 51 may vary between 30 kg and 80 kg or more.
Figure 3 shows slosh damper disc 51 coupled to a handling tool 100. The handling tool 100 comprises a first arm 101, a second arm 102 and a third arm 103, to be coupled to the
DK 2021 70173 A1 slosh damper disc 51, as better explained in the following. The handling tool 100 provides an interface between a slosh damper disc 51 and a handling device (not represented in the attached figures), for example a crane, which is used to han- 5 dle the slosh damper disc. The handling device 100 may be conveniently and stably attached to the crane, for example by means of ropes or chains attached to the handling tool 100, for example to the first arm 101, a second arm 102 and a third arm 103.
Figures 4 and 5 show the handling tool 100 in better detail. The handling tool 100 comprises a central U-shaped structure 105, from which the first, second and third arm 101, 102, 103 extends up to a respective free end including a respective clamp 104. Each clamp 104 is usable for fixing a border of a slosh damper disc 51 to the handling tool 100. The second arm 102 is inclined with respect to the first arm 101 of a first angle o comprised between 45 deg and 135 deg. In the embodi- ment of the attached figures the first angle o measures 90 deg. The third arm 103 is inclined with respect to the first arm 101 of a second angle f comprised between 45 deg and 135 deg. In the embodiment of the attached figures the second an- gle Bf measures 90 deg. In the embodiment of the attached fig- ures the first, second and third arm 101, 102, 103 lie on a common plane and extend radially from the central structure 105, Alternatively, the handling tool 100 may have a three- dimensional design, i.e. extending in a direction perpendicu- lar to the plane defined by the three clamps 104. In the lat- ter case the first angle o and the second angle R are measures in a projection of the first, second and third arm 101, 102, 103 on the plane defined by the three clamps 104. To facilitate the coupling of the handling tool 100 with slosh damper discs 51 of different diameters, any of the first, second and third arm 101, 102, 103 may be a telescopic arm, as shown in the attached figures. Fach arm 101, 102, 103 includes a first respective portion 101a, 102a, 103a fixed to the central U-shaped structure 105 and a second respective
DK 2021 70173 A1 6 portion 101b, 102b, 103b fixed to the respective clamp 104. Fach second portion 101b, 102b, 103b is translatable with re- spect to the first portion 10la, 102a, 103a to regulate the length of the respective arm 101, 102, 103. Each second por- tion 101b, 102b, 103b is fixable to the respective first por- tion 101a, 102a, 103a to block the length of the respective arm 101, 102, 103. According to other embodiments (not shown) only one or two of the three arms 101, 102, 103 are telescop- ic.
According to other embodiments (not shown) the handling tool 100 comprises more than three arms 101, 102, 103, for example four arms, for example four arms disposed along two perpen- dicular directions, i.e. with an angle of 90 deg between two angularly consecutive arms.
