[0033] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown to avoid unnecessarily obscuring the utility model; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0034] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the cable clamping device, tower, or wind turbine generator of this utility model. In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Please see Figure 1As shown in the figure, this application provides a wind turbine generator set, including a tower 1, a nacelle 2, a generator 3, and a rotor 4. The tower 1 is connected to the wind turbine foundation and is composed of multiple tower sections. The nacelle 2 is located at the top of the tower 1, and the generator 3 is located in the nacelle 2. In some examples, the generator 3 can be located outside the nacelle 2; in other examples, the generator 3 can be located inside the nacelle 2. The rotor 4 includes blades 420 and a hub 410. Multiple blades 420 are connected to the hub 410. When wind power acts on the blades 420, it drives the entire rotor 4 and the shaft of the generator 3 to rotate, thereby converting wind energy into electrical energy.

[0036] Please see Figure 1 , Figure 2 As shown, tower 1 includes tower body 200 and adapter frame 300, with adapter frame 300 connected inside tower body 200. To achieve energy and data transmission, the components at the bottom of tower 1 and its top are typically connected via cable aa. Therefore, tower 1 may also include cable clamping device 100, which clamps and fixes cable aa to the corresponding adapter frame 300 and other structures on tower 1, ensuring the safety of cable aa and reducing the probability of cable aa tangling.

[0037] However, the cable clamping device 100 in the related technology is connected to the adapter frame 300 and other structures by means of snap-fit. Due to structural limitations, after clamping and fixing the cable aa, it is not conducive to fixing the cable aa to the adapter frame 300 and other structures in the environment where the cable aa is located, which affects the reliability of fixing the cable aa.

[0038] Based on the above deficiencies, this application provides a cable clamping device 100 that can meet the clamping and fixing requirements of cable aa and ensure the fixation with structures such as the adapter frame 300 in the environment where cable aa is located.

[0039] The cable clamping device 100 provided in this application embodiment can be manufactured and sold separately as an independent component, and is suitable for various cable installation environments. Of course, the cable clamping device 100 can also be used in the tower 1 and as a component of the tower 1.

[0040] Please see Figures 2 to 4As shown, an embodiment of this application provides a cable clamping device 100, including a clamping assembly 10, an anti-detachment member 30, and a connecting assembly 20. The clamping assembly 10 includes a first clamping portion 11 and a second clamping portion 12 distributed along a first direction X. The first clamping portion 11 and the second clamping portion 12 enclose a clamping cavity 10a. The anti-detachment member 30 is disposed on the side of the first clamping portion 11 opposite to the second clamping portion 12 in the first direction X. The connecting assembly 20 is connected to the clamping assembly 10 and the anti-detachment member 30. The connecting assembly 20 includes two or more first connecting members 21. Each first connecting member 21 is inserted into the first clamping portion 11, the second clamping portion 12, and the anti-detachment member 30 along the first direction X. The first connecting member 21 is detachably connected to the anti-detachment member 30. At least one of the first clamping portion 11 and the second clamping portion 12 is clearance-fitted with the first connecting member 21.

[0041] Optionally, the first direction X can be represented as the thickness direction of the first clamping part 11.

[0042] The clamping cavity 10a is used to accommodate cable aa, so as to clamp and fix cable aa between the first clamping part 11 and the second clamping part 12, to ensure the relative fixation of cable aa and the adapter frame 300, and to ensure the safety of cable aa.

[0043] The first connector 21 can be fitted with and movably connected to at least one of the first clamping part 11 and the second clamping part 12 along the first direction X to adjust the distance between the first clamping part 11 and the second clamping part 12 along the first direction X, thereby adjusting the size of the clamping cavity 10a so that the clamping assembly 10 can clamp and fix cables aa of different specifications. Furthermore, after the cable aa is laid, the torque of the first connector 21 can be adjusted, i.e., the first connector 21 can be moved along the first direction X to adjust the clamping force of the clamping assembly 10, so that it can clamp the cable aa more firmly.

[0044] The first clamping part 11 and the second clamping part 12 may have a cavity on one of them and a flat plate structure on the other, with the two enclosing each other to form a clamping cavity 10a. Of course, in some embodiments, both the first clamping part 11 and the second clamping part 12 may have cavities, with the cavities of the two arranged opposite each other to enclose and form the clamping cavity 10a.

[0045] The first clamping part 11 can be made of a structure such as an aluminum alloy block or a die-cast nylon block, and the second clamping part 12 can also be made of a structure such as an aluminum alloy block or a die-cast nylon block. Optionally, the materials of the first clamping part 11 and the second clamping part 12 can be the same, or they can be different. For example, the first clamping part 11 can be made of a die-cast nylon block, and the second clamping part 12 can be made of an aluminum alloy block.

[0046] The clamping cavity 10a can hold one or more cables aa, and when it is multiple, three cables can be selected.

[0047] The anti-detachment component 30, the first clamping part 11, and the second clamping part 12 can all be provided with insertion holes, so that the first connector 21 can be inserted into the first clamping part 11, the second clamping part 12, and the anti-detachment component 30 along the first direction X.

[0048] The anti-detachment component 30 and the first connecting component 21 can be directly and detachably connected, for example, by means of a threaded connection. Alternatively, in some embodiments, a limiting structure can be provided on the side of the anti-detachment component 30 facing away from the first clamping portion 11 in the first direction X. This limiting structure is detachably connected to the first connecting component 21. This also ensures the detachable connection requirement with the anti-detachment component 30.

[0049] One embodiment of this application provides a cable clamping device 100, which can accommodate cable aa by a clamping cavity 10a formed by a first clamping part 11 and a second clamping part 12, thereby clamping and fixing cable aa. The device includes an anti-detachment component 30 and a connecting assembly 20, with the connecting assembly 20 comprising two or more first connecting members 21. Each first connecting member 21 is inserted into the first clamping part 11, the second clamping part 12, and the anti-detachment component 30 along a first direction X. At least one of the first clamping part 11 and the second clamping part 12 is clearance-fitted with the first connecting member 21, allowing the first clamping part 11 and the second clamping part 12 to be connected as a whole through the first connecting members 21, ensuring the clamping and fixing requirements of cable aa. Furthermore, the relative positions of the first clamping part 11 and the second clamping part 12 in the first direction X are adjustable, and the size of the corresponding clamping cavity 10a is adjustable to accommodate clamping and fixing cables aa of different specifications and sizes. Meanwhile, the anti-detachment component 30 is disposed on the side of the first clamping part 11 opposite to the second clamping part 12 in the first direction X and is detachably connected to the first connector 21. The anti-detachment component 30 can be connected to the first clamping part 11 through the first connector 21, so that the two are clamped together on the environmental component where the cable aa is located, ensuring the connection and fixation between the cable clamping device 100 and the adapter frame 300 and other components in the environment where the cable aa is located, thereby ensuring the reliability of fixing the cable aa.

[0050] In some optional embodiments, the cable clamping device 100 provided in one embodiment of this application includes an anti-detachment component 30 comprising a limiting plate 31 and a plurality of locking caps 32. The limiting plate 31 is provided with a socket corresponding to each first connector 21. The first connector 21 is inserted into the socket and is clearance-fitted with the limiting plate 31. Each locking cap 32 is disposed on the side of the limiting plate 31 away from the clamping assembly 10 in the first direction X. Each locking cap 32 is detachably connected to one of the first connectors 21.

[0051] The number of insertion holes provided on the limiting plate 31 can be two, three, or more. The number of locking caps 32 can be equal to the number of insertion holes and set one-to-one. Each insertion hole and locking cap 32 is provided with a corresponding first connector 21. The first connector 21 can be inserted into the first clamping part 11, the second clamping part 12, and the limiting plate 31, and protrudes from the limiting plate 31 in the first direction X on the side opposite to the first clamping part 11. The part protruding from the limiting plate 31 can be detachably connected to the locking cap 32.

[0052] The first connector 21 and the locking cap 32 can be detachably connected by a threaded connection or a snap-fit ​​mechanism, with a threaded connection being an option.

[0053] One embodiment of this application provides a cable clamping device 100. During operation, the first clamping part 11 and the limiting plate 31 are clamped onto a connecting structure such as an adapter frame 300. The first connecting member 21 is inserted into and engages with the second clamping part 12, the first clamping part 11, the adapter frame 300, and the limiting plate 31. Then, a locking cap 32 is detachably connected to the first connecting member 21 to prevent the limiting plate 31 from disengaging from the first connecting member 21. This configuration allows the cable clamping device 100 to be clamped and fixed onto the adapter frame 300 by the limiting plate 31 and the first clamping part 11. Furthermore, the limiting plate 31 allows for the unrestricted size of the holes on the adapter frame 300 through which the first connecting member 21 passes, providing a mounting surface for the locking cap 32 and ensuring the stability of the cable clamping device 100's installation and fixation. Moreover, this configuration allows for the installation and locking of multiple first connecting members 21 through the limiting plate 31 and the locking cap 32, improving connection strength.

[0054] In some alternative embodiments, a cable clamping device 100 provided in one embodiment of this application has a locking cap 32 with a threaded hole extending along a first direction X, each threaded hole being disposed opposite to one of the insertion holes, the locking cap 32 being connected to a limiting plate 31, and a first connecting member 21 including a screw 211, the screw 211 being inserted into the first clamping part 11, the second clamping part 12, the limiting plate 31 and the locking cap 32 and being threadedly connected to the locking cap 32.

[0055] The locking cap 32 and the limiting plate 31 can be connected by welding, adhesive bonding or other methods.

[0056] The screw 211 may be provided with an end cap 212. The screw 211 is inserted into the first clamping part 11, the second clamping part 12, the limiting plate 31 and threadedly connected to the locking cap 32. The end cap 212 is provided on the side of the second clamping part 12 away from the first clamping part 11 and limits the second clamping part 12.

[0057] One embodiment of this application provides a cable clamping device 100 that connects the locking cap 32 and the first connecting member 21 via a threaded connection. This facilitates a detachable connection between the two and utilizes the self-locking property of the thread to reduce the risk of separation between the cable clamping device 100 and the adapter frame 300. Furthermore, by connecting the locking cap 32 to the limiting plate 31, the limiting plate 31 provides support for the locking cap 32. When disassembling the first connecting member 21, it is not necessary to limit the locking cap 32; simply tightening the screw 211 is sufficient, reducing the difficulty of assembly and disassembly. Even if the first connecting member 21 is separated from the locking cap 32, the locking cap 32 will not fall off, reducing disassembly failures.

[0058] In some alternative embodiments, the surfaces of the first clamping part 11 and the anti-detachment member 30 facing each other in the first direction X are both planar and arranged parallel to each other.

[0059] With the above settings, the first clamping part 11 and the anti-detachment part 30 can have a large contact area with the adapter frame 300 under the action of the connector, thus ensuring the connection strength.

[0060] In some optional embodiments, a cable clamping device 100 provided in one embodiment of this application includes a first clamping part 11 including a first recess 101 and a second clamping part 12 including a second recess 102. The first recess 101 and the second recess 102 are recessed in a direction opposite to each other along a first direction X. The first recess 101 and the second recess 102 communicate to form a clamping cavity 10a.

[0061] The first recess 101 and the second recess 102 can have the same structure. Of course, in some embodiments, the structure of the first recess 101 and the second recess 102 can also be different. For example, the groove structure of the first recess 101 and the second recess 102 can be different, so that the number of cables aa accommodated by the two is different.

[0062] Both the first recess 101 and the second recess 102 can include an arc-shaped groove structure.

[0063] One embodiment of this application provides a cable clamping device 100. Through the above-mentioned configuration, the first clamping part 11 and the second clamping part 12 can both provide limiting for the cable aa through the first recess 101 and the second recess 102, thereby reducing the risk of the cables aa moving around each other and ensuring the reliability of the cable aa being fixed.

[0064] In some alternative embodiments, a cable clamping device 100 provided in one embodiment of this application includes a first recess 101 comprising a pair of first arc-shaped grooves 1011 symmetrically distributed along a second direction Y, and a second recess 102 comprising a second arc-shaped groove 1021, the center of which is located on the axis of symmetry of the pair of first arc-shaped grooves 1011, and the second direction Y intersects with the first direction X.

[0065] The angle between the second direction Y and the first direction X can be 90°, meaning that they can be perpendicular to each other.

[0066] The center of the second arc-shaped groove 1021 is located on the axis of symmetry of the paired first arc-shaped grooves 1011. This can be understood as the distance between the center of the second arc-shaped groove 1021 and the center of the paired first arc-shaped grooves 1011 being equal. Alternatively, it can be understood as the line connecting the center of the second arc-shaped groove 1021 and the centers of the two first arc-shaped grooves 1011 forming an isosceles triangle.

[0067] One embodiment of this application provides a cable clamping device 100. Through the above-described configuration, when the first recess 101 and the second recess 102 are connected to form a clamping cavity 10a, the clamping cavity 10a can distribute three cables aa in a triangular shape, ensuring the stability of clamping and fixing the cables aa.

[0068] Please see Figure 5 As shown, in some optional embodiments, the cable clamping device 100 provided in one embodiment of this application has a first arc groove 1011 and a second arc groove 1021, both of which are circular arc grooves. The radius of the circle in which the first arc groove 1011 is located is R1, and the radius of the circle in which the second arc groove 1021 is located is R2, wherein the absolute value of the difference between R1 and R2 is less than or equal to 2mm.

[0069] The bottom wall surfaces of both the first arc-shaped groove 1011 and the second arc-shaped groove 1021 can be circular arc surfaces. The first arc-shaped groove 1011 and the second arc-shaped groove 1021 can each be a segment cut from a whole circle.

[0070] The absolute value of the difference between R1 and R2 can be any value between 0 and 2 mm, including both 0 mm and 2 mm.

[0071] One embodiment of this application provides a cable clamping device 100, which, through the above-described configuration, can ensure the clamping and fixing requirements of each cable aa and guarantee the reliability of the clamping and fixing.

[0072] In some alternative embodiments, a cable clamping device 100 provided in one embodiment of this application has a first notch 122 provided on the second clamping part 12 corresponding to each of its plug holes. The first notch 122 starts from one end face of the second clamping part 12 along the height direction Z and extends to the plug hole on the second clamping part 12.

[0073] Optionally, the first notch 122 may be a U-shaped opening and communicate with the insertion hole on the second clamping part 12 in the height direction Z.

[0074] The cable clamping device 100 provided in one embodiment of this application, through the above-mentioned configuration, allows the cable aa to be assembled without separating it from the first clamping part 11 after the first connector 21 is loosened. The first clamping part 11 and the second clamping part 12 are separated by lifting the second clamping part 12 along the height direction Z, which facilitates the assembly and disassembly of the cable aa.

[0075] In some optional embodiments, the cable clamping device 100 provided in one embodiment of this application further includes an anti-separation member 60, which is connected between the first clamping part 11 and the second clamping part 12, so that the second clamping part 12 is prevented from falling off when it is disassembled, thereby improving safety. Optionally, the anti-separation member 60 may be a flexible cable or the like.

[0076] Please continue reading. Figures 2 to 5 As shown, in some optional embodiments, the cable clamping device 100 provided in one embodiment of this application further includes an anti-slip structure 40, which is disposed in at least one of the first clamping part 11 and the second clamping part 12 and protrudes toward the clamping cavity 10a.

[0077] Optionally, when the first clamping part 11 includes a first recess 101 and the second clamping part 12 includes a second recess 102, an anti-slip structure 40 may be provided on at least one of the first recess 101 and the second recess 102. The anti-slip structure 40 is used to increase the coefficient of friction between the cable aa and the first clamping part 11 and the second clamping part 12, so as to enhance the fixing effect of the clamping assembly 10 on the cable aa.

[0078] The cable clamping device 100 provided in some embodiments of this application effectively fixes the cable aa by setting the anti-slip structure 40, preventing the cable aa from loosening or falling off.

[0079] Optionally, the first clamping part 11 may be provided with an anti-slip structure 40, and the second clamping part 12 may also be provided with an anti-slip structure 40. Of course, both the first clamping part 11 and the second clamping part 12 may be provided with an anti-slip structure 40 at the same time.

[0080] Optionally, the anti-slip structure 40 can be configured as a strip structure extending along the second direction Y. The anti-slip structure 40 can include a whole strip structure extending along the second direction Y, or it can be a discontinuous strip structure.

[0081] As an alternative implementation, the anti-slip structure 40 has a length dimension in the first direction X between 0.9 mm and 1 mm.

[0082] By setting the length of the anti-slip structure 40 in the first direction X to between 0.9mm and 1mm, including the two endpoint values ​​of 0.9mm and 1mm, the stability of cable aa in the clamping cavity 10a can be better improved, while ensuring that the anti-slip structure 40 can play an anti-slip role for cable aa, thereby improving the reliability and stability of the cable clamping device 100.

[0083] As an optional implementation, the anti-slip structure 40 includes a plurality of first anti-slip portions 41 disposed on the first clamping portion 11. The plurality of first anti-slip portions 41 are distributed at intervals along the height direction Z of the first clamping portion 11. The first anti-slip portions 41 and the first clamping portion 11 can be an integral structure.

[0084] By setting multiple first anti-slip parts 41 and distributing them at intervals along the height direction Z, it is possible to better prevent cable aa from shifting within the clamping cavity 10a. Furthermore, by integrally molding the first anti-slip parts 41 with the first clamping parts 11, it is beneficial to improve processing efficiency and the connection strength between the two, avoiding the problem of the first anti-slip parts 41 becoming loose and failing due to long-term contact with cable aa, thus improving the reliability of the cable clamping device.

[0085] For example, the number of first anti-slip parts 41 is set to four, and the four first anti-slip parts 41 are distributed at equal intervals along the height direction Z, which is convenient for processing and can meet the anti-slip effect.

[0086] Optionally, the side of the first anti-slip part 41 facing away from the first clamping part 11 may be arc-shaped to prevent it from scratching the cable aa.

[0087] Optionally, the cross-sectional shape of the first anti-slip part 41 can be semi-circular, trapezoidal, etc., to prevent it from scratching the cable aa.

[0088] As an optional implementation, the anti-slip structure 40 includes a plurality of second anti-slip portions 42 disposed on the second clamping portion 12. The plurality of second anti-slip portions 42 are distributed at intervals along the height direction Z. The second anti-slip portions 42 may be integral with the second clamping portion 12. The height direction Z intersects with the first direction X and the second direction Y, and may be perpendicular to each other.

[0089] By providing multiple second anti-slip parts 42 and distributing them at intervals along the height direction Z, it is possible to better prevent cable aa from shifting within the clamping cavity 10a. Furthermore, by integrally molding the second anti-slip parts 42 with the second clamping parts 12, it is beneficial to improve processing efficiency and the connection strength between them, avoiding the problem of the second anti-slip parts 42 becoming loose and failing due to long-term contact with cable aa, and thus improving the reliability of the cable clamping device 100.

[0090] For example, the number of second anti-slip parts 42 is set to four, and the four second anti-slip parts 42 are distributed at equal intervals along the height direction Z, which is convenient for processing and can meet the anti-slip effect.

[0091] Optionally, the side of the second anti-slip part 42 facing away from the second clamping part 12 may be arc-shaped to prevent it from scratching the cable aa.

[0092] Optionally, the cross-sectional shape of the second anti-slip part 42 can be semi-circular, trapezoidal, etc., to prevent it from scratching the cable aa.

[0093] For example, the anti-slip structure 40 includes a plurality of first anti-slip portions 41 disposed on the first clamping portion 11 and a plurality of second anti-slip portions 42 disposed on the second clamping portion 12. The plurality of first anti-slip portions 41 are distributed at intervals along the height direction Z, and the first anti-slip portions 41 and the first clamping portion 11 are an integral structure. The plurality of second anti-slip portions 42 are distributed at intervals along the height direction Z, and the second anti-slip portions 42 and the second clamping portion 12 are an integral structure.

[0094] Optionally, the orthographic projection of the first anti-slip part 41 in the first direction X and the orthographic projection of the second anti-slip part 42 in the first direction X can overlap, or they can be staggered.

[0095] In some alternative embodiments, the cable clamping device 100 provided in one embodiment of this application further includes an anti-scratch part 50. The anti-scratch part 50 is disposed on the side of the second clamping part 12 away from the second clamping part 12 along the first direction X. The anti-scratch part 50 protrudes from the second clamping part 12 and has an arc-shaped structure on the side of the anti-scratch part 50 away from the second clamping part 12.

[0096] By providing an anti-scratch part 50 in the second clamping part 12, the first connector 21 can be prevented from scratching the cable aa or other components during operation, which helps to improve the protective effect of the cable clamping device on the cable aa, thereby improving the reliability of the cable aa fixing device.

[0097] Optionally, the anti-scratch part 50 has an arc-shaped structure on the side facing away from the second clamping part 12. This can be understood as the anti-scratch part 50 being chamfered on the side facing away from the second clamping part 12 along the first direction X, so that it will not scratch the line aa when it comes into contact with the line aa.

[0098] In some alternative embodiments, the second clamping portion 12 is provided with anti-scratch portions 50 on both sides along the height direction Z.

[0099] Since the cable aa is laid along the height direction Z when the cable clamping device is used, the anti-scratch part 50 is provided on both sides of the second clamping part 12 along the height direction Z. This allows the cable aa to contact the anti-scratch part 50 and avoid contact with the fixing part, thus preventing the cable aa from being scratched. It also helps to reduce the processing difficulty and cost.

[0100] In some alternative embodiments, the second clamping part 12 is provided with anti-scratch parts 50 on both sides along the height direction Z and on both sides along the second direction Y. This arrangement can better ensure the protective effect of the cable clamping device on the cable aa.

[0101] Optionally, the anti-scratch part 50 and the second clamping part 12 are integrated into one structure, which helps to improve processing efficiency and the connection strength between the anti-scratch part 50 and the second clamping part 12. Of course, the anti-scratch part 50 and the second clamping part 12 can also be provided separately, which helps to reduce processing difficulty and improve the flexibility of use.

[0102] In some alternative embodiments, the anti-scratch portion 50 provided on the second clamping portion 12 may protrude from the end cap 212 of the first connector 21 along the first direction X, so as to reduce the probability of the end cap 212 abrading the cable aa.

[0103] In some optional embodiments, the cable clamping device 100 provided in one embodiment of this application has a limiting groove provided on the side of the second clamping part 12 away from the first clamping part. The limiting groove is provided corresponding to the end cap 212, and the end cap 212 is partially located in the limiting groove, which facilitates the installation and positioning of the end cap.

[0104] Optionally, the connecting assembly 20 may further include a washer, which is sleeved on the screw 211 and abuts against the end cap 212 on the side facing the first clamping portion 11 in the first direction X. The washer is disposed in a limiting groove and engages with the second clamping portion 12. This arrangement allows the washer to be pressed into the limiting groove by the end cap 212, which improves the connection strength between the washer and the second clamping portion 12. Furthermore, it facilitates the operator's operation of the screw 211; for example, the end cap 212 can be screwed to move the screw 211 in the first direction X.

[0105] In some optional embodiments, one embodiment of the present application provides a cable clamping device 100 with multiple clamping cavities 10a distributed at intervals along the second direction Y, and each clamping cavity 10a has a first connector 21 corresponding to both sides.

[0106] The number of clamping cavities 10a can be two, three, or more, depending on the number of cables aa to be clamped. Each clamping cavity 10a is provided with a corresponding second connector 22.

[0107] One embodiment of this application provides a cable clamping device 100, which, through the above-described configuration, facilitates the simultaneous clamping and fixing of multiple sets of cables aa.

[0108] The tower 1 and wind turbine generator provided in some embodiments of this application, by including the cable clamping device 100 provided in the above embodiments, can ensure the fixing requirements of cable aa and ensure the reliability of operation.

[0109] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
