[0048] 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.
[0049] 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 fixing device, tower, and wind turbine generator set of this utility model. It should also be noted in the description of this utility model 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.
[0050] 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 rotor of the generator 3 to rotate relative to the stator, thereby converting wind energy into electrical energy.
[0051] 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 fixing device 100, which clamps and fixes cable aa to the corresponding adapter frame 300 or other structures on tower 1, ensuring the safety of cable aa and reducing the probability of cable aa tangling.
[0052] However, the cable fixing 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, it is not conducive to fixing the cable fixing device to external components after clamping and fixing the cable aa, which affects the reliability of cable fixing.
[0053] Based on the above deficiencies, this application provides a cable fixing device 100, which can meet the clamping and fixing requirements of cable aa, and can ensure the fixing of cable fixing device 100 to external components such as adapter frame 300.
[0054] The cable fixing device 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 fixing device 100 can also be used in the tower 1 and be a component of the tower 1.
[0055] Please see Figures 2 to 4As shown, an embodiment of this application provides a cable fixing device 100, including a clamping assembly 10 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, and the first clamping portion 11 and the second clamping portion 12 surround to form a clamping cavity 10a. The connecting assembly 20 is disposed on the clamping assembly 10, and the connecting assembly 20 includes a first connector 21 and a second connector 22. There are multiple first connectors 21, which are respectively connected to the first clamping portion 11 and the second clamping portion 12. The second connector 22 is connected to the first clamping portion 11 and protrudes from the first clamping portion 11 along the first direction X in a direction away from the clamping cavity 10a, so as to connect with an external component.
[0056] Optionally, the first direction X can be represented as the thickness direction of the first clamping part 11.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] The clamping cavity 10a can hold one or more cables aa, and when it is multiple, three cables can be selected.
[0061] 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.
[0062] The number of first connectors 21 can be two, three, or more. Optionally, first connectors 21 can be provided on both sides of the clamping cavity 10a.
[0063] The second connector 22 can be connected to the first clamping part 11 by a fixed or detachable connection method, and a detachable connection method can be selected. The portion of the second connector 22 that protrudes from the first clamping part 11 can be connected to external components such as the adapter frame 300 by means of threaded connection, interference fit, etc.
[0064] One embodiment of this application provides a cable fixing device 100, including a clamping assembly 10 and a connecting assembly 20. The clamping assembly 10 includes a first clamping portion 11 and a second clamping portion distributed along a first direction X. The connecting assembly 20 includes a first connector 21 and a second connector 22. A plurality of first connectors 21 connect the first clamping portion 11 and the second clamping portion 12 for clamping and fixing a cable located in a clamping cavity 10a. The second connector 22 is connected to the first clamping portion 11 and protrudes from the first clamping portion 11 in the first direction X in a direction away from the clamping cavity 10a, so that the second connector 22 can be connected to an external component such as an adapter frame 300, ensuring the connection requirements between the cable fixing device 100 and external components such as the adapter frame 300, thereby ensuring the reliability of fixing the cable aa.
[0065] In some alternative embodiments, a cable fixing device 100 provided in one embodiment of this application has a first clamping part 11 having a countersunk hole 114 on the side facing the second clamping part 12 in the first direction X, and a second connector 22 having one end located in the countersunk hole 114 in the first direction X and the other end protruding from the first clamping part 11.
[0066] The second connector 22 can be inserted into the first clamping part 11 and protrude from the first clamping part 11. Optionally, the second connector 22 can be inserted into the first clamping part 11 along the first direction X and protrude from the other end of the first clamping part 11.
[0067] Optionally, the countersunk hole 114 may be a stepped hole and is provided to pass through the first clamping part 11 along the first direction X.
[0068] One embodiment of this application provides a cable fixing device 100, which has a countersunk hole 114 on the side of the first clamping part 11 facing the second clamping part in the first direction X, and the end of the second connector 22 facing the clamping cavity 10a can be located in the countersunk hole 114. This effectively avoids the second connector 22 protruding into the clamping cavity 10a and causing wear to the cable in the clamping cavity 10a, thus ensuring the reliability of clamping and fixing the cable aa.
[0069] Please see Figures 2 to 5As shown, in some optional embodiments, a cable fixing device 100 provided in one embodiment of this application has a clamping cavity 10a with first connectors 21 respectively provided on both sides of the second direction Y. In the second direction Y, a second connector 22 is provided between two adjacent first connectors 21, and the vertical distance between the second connector 22 and the two adjacent first connectors 21 is equal. The second direction Y intersects with the first direction X.
[0070] Optionally, the second direction Y and the first direction X can be perpendicular to each other.
[0071] Optionally, the cable fixing device 100 may include one clamping cavity 10a, or more than two. When there are two or more, the clamping cavities 10a are spaced apart along the second direction Y, and each clamping cavity 10a has a first connector 21 on both sides. Optionally, the first connector 21 of two adjacent clamping cavities 10a may be independently provided, or two adjacent clamping cavities 10a may share a first connector 21.
[0072] Optionally, each clamping cavity 10a may be provided with a corresponding second connector 22.
[0073] The vertical distance between the second connector 22 and the two adjacent first connectors 21 can be understood as the vertical distance between the central axis of the second connector 22 extending along the first direction X and the central axis of each of the two adjacent first connectors 21 extending along the first direction X.
[0074] Optionally, two adjacent first connectors 21 can be symmetrically distributed on both sides of the second connector 22 between them.
[0075] One embodiment of this application provides a cable fixing device 100, which ensures that the vertical distance between the second connector 22 and the two adjacent first connectors 21 is equal. This reduces the probability of the cable fixing device 100 bearing off-center load when it is connected to external components such as the adapter frame 300, and increases the contact area between the cable fixing device 100 and external components such as the adapter frame 300, thus ensuring the connection strength between the two.
[0076] Please see Figures 3 to 8 As shown, in some optional embodiments, a cable fixing device 100 provided in one embodiment of this application includes a first connecting member 21 comprising a first connecting rod 211 and a first locking cap 212. The first connecting rod 211 is inserted into the first clamping part 11 and the second clamping part 12. A groove 112a is provided on one of the first clamping part 11 and the second clamping part 12. The first locking cap 212 is snapped into the groove 112a and detachably connected to the first connecting rod 211.
[0077] The first connecting rod 211 may optionally include a screw with an end cap, and the first locking cap 212 may optionally include a nut. The first connecting rod 211 and the first locking cap 212 may be connected by a threaded connection. Of course, this is an optional embodiment. In some embodiments, the first connecting rod 211 and the first locking cap 212 may be detachably connected to each other by a snap-fit engagement, for example, one has a protrusion and the other has a buckle, with the protrusion extending into the buckle and being detachably connected to each other.
[0078] A groove 112a can be provided on one of the first clamping part 11 and the second clamping part 12, and the shape of the groove 112a can match the shape of the first locking cap 212. The first locking cap 212 can be snapped and fixed in the first clamping part 11.
[0079] One embodiment of this application provides a cable fixing device 100, which, through the above-described configuration, ensures that the first connector 21 can meet the connection requirements between the first clamping part 11 and the second clamping part 12. Furthermore, the groove 112a provides installation and fixing space for the first locking cap 212, reducing the probability of parts falling out or being lost during assembly and disassembly of the first connector 21.
[0080] In some optional embodiments, one embodiment of the cable fixing device 100 provided in this application has a groove 112a disposed in a first clamping portion 11. The groove 112a is recessed from the side of the first clamping portion 11 opposite to the second clamping portion 12 in the first direction X toward the side where the second clamping portion 12 is located. The sidewall of the first clamping portion 11 surrounding the groove 112a is provided with a clearance notch 112c. Optionally, the first locking cap 212 may be partially exposed in the clearance notch 112c at one end in the first direction X toward the second clamping portion 12.
[0081] The clearance notch 112c opened on the side wall of the groove 112a can be a polygonal groove, or optionally a U-shaped groove.
[0082] One embodiment of this application provides a cable fixing device 100. By placing the first locking cap 212 on the side of the first clamping part 11 away from the second clamping part 12, the device facilitates the fixing of the first locking cap 212 and avoids interference between the first locking cap 212 and the relative displacement between the first clamping part 11 and the second clamping part 12. Furthermore, the provision of the clearance notch 112c allows the end of the first locking cap 212 facing the clamping cavity 10a in the first direction X to be exposed. When the first locking cap 212 needs to be replaced due to wear or other reasons, it can be pried open by the clearance notch 112c, allowing it to be quickly separated from the groove 112a, reducing the difficulty of replacing the first locking cap 212.
[0083] In some optional embodiments, the cable fixing device 100 provided in one embodiment of this application may optionally include a first clamping part 11 including multiple hollow holes. The first clamping part may be partially hollowed out, which can reduce weight and cost.
[0084] In some optional embodiments, a cable fixing device 100 provided in one embodiment of this application includes a first clamping part 11 including a first base 111 and first connecting seats 112 disposed on both sides of the first base 111 in a second direction Y.

Each first connecting seat 112 is provided with a first groove 112a. A second connector 22 is connected to the first base 111.
[0085] Along the first direction X, the thickness of the first connecting seat 112 is less than the thickness of the first base 111.
[0086] Each first connecting seat 112 has a first locking cap 212 in its groove 112a, and correspondingly, each first connecting seat 112 has a first connecting rod 211 inserted into it.
[0087] The cable fixing device 100 provided in one embodiment of this application, through the above-described configuration, facilitates the reduction of the length of the first connector 21 while ensuring the clamping requirements of cable aa, thereby reducing costs and the probability of deformation of the first connector 21.
[0088] Continue reading Figure 8 As shown, in some optional embodiments, a cable fixing device 100 provided in one embodiment of this application has a first base 111 with a marking 112b protruding from the first connector 112. The marking 112b includes at least one of scale lines and numbers.
[0089] The identifier 112b may optionally include a combination of scale lines and numbers.
[0090] The cable fixing device 100 provided in one embodiment of this application can adjust the position of the first locking cap 212 on the first connecting rod 211 by means of the mark 112b provided on the first base 111 when clamping a cable of a corresponding radial size, thereby reducing the difficulty of adjustment and allowing adjustment according to the pre-set size requirements, thus improving assembly efficiency.
[0091] Please see Figure 9 as well as Figure 10As shown, in some optional embodiments, a cable fixing device 100 provided in one embodiment of this application has a first mounting hole 113 on a first clamping part 11 and a second mounting hole 121 on a second clamping part 12 that is opposite to the first mounting hole 113. A first connecting rod 211 is inserted into the first mounting hole 113 and the second mounting hole 121 and is in clearance fit with the first clamping part 11 and the second clamping part 12.
[0092] The first clamping part 11 may have two or more first mounting holes 113, which are spaced apart along the second direction Y.

The number of first mounting holes 113 and second mounting holes 121 may be the same and they may be arranged one-to-one.
[0093] The cable fixing device 100 provided in one embodiment of this application, through the above-mentioned arrangement, allows the first clamping part 11 and the second clamping part 12 to slide and cooperate with the first connecting rod 211, which facilitates the adjustment of the relative position between the first clamping part 11 and the second clamping part 12 to adapt to the clamping and fixing requirements of cables with different radial dimensions.
[0094] Please continue reading. Figure 9 as well as Figure 10 As shown, in some optional embodiments, a cable fixing device 100 provided in one embodiment of this application has a first notch 122 provided on the second clamping part 12 corresponding to each second mounting hole 121. The first notch 122 starts from one end face of the second clamping part 12 along the height direction Z and extends to the second mounting hole 121.
[0095] Optionally, the first notch 122 may be a U-shaped opening and communicate with the second mounting hole 121 in the height direction Z.
[0096] The cable fixing device 100 provided in one embodiment of this application, through the above-mentioned arrangement, 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.
[0097] In some optional embodiments, the cable fixing device 100 provided in one embodiment of this application includes a second clamping part 12 including a first partition part 122a and a second partition part 122b located on both sides of a first notch 122, and at least one first partition part 122a and a second partition part 122b corresponding to the first notch 122 have a height difference in the height direction Z.
[0098] The height difference can be formed by removing a portion of the material along the height direction Z on the first partition 122a or the second partition 122b.
[0099] Optionally, along the second direction Y, the width of the first partition 122a may be smaller than the width of the second partition 122b, and the second partition 122b may be set higher than the first partition 122a.
[0100] The cable fixing device 100 provided in one embodiment of this application, through the above-described configuration, reduces the difficulty of disassembling and assembling the second clamping part 12 when it is separated from or connected to the connecting component, and improves the disassembly and assembly efficiency.
[0101] Please continue reading. Figure 4 , Figure 9 as well as Figure 10 As shown, in some optional embodiments, the cable fixing device 100 provided in one embodiment of this application further includes an anti-detachment member 60, which is connected between the first clamping part 11 and the second clamping part 12, so that when the second clamping part 12 is disassembled, the second clamping part 12 is prevented from falling off, thereby improving safety.
[0102] Optionally, a connecting hole 112d may be provided on the first clamping part 11 for connecting the anti-detachment component 60.
[0103] Of course, it is understandable that the above-described cooperation between the first connecting rod 211 and the first clamping part 11 and the second clamping part 12 is only one optional implementation.
[0104] Please see Figure 11 as well as Figure 12 As shown, in some embodiments, the first clamping part 11 may be provided with a first mounting hole 113, and the second clamping part 12 may be provided with a second mounting hole 121 opposite to the first mounting hole 113. The first mounting hole 113 and the second mounting hole 121 are threaded holes. The first connecting rod 211 includes a first rod segment 211a and a second rod segment 211b along the first direction X. The first rod segment 211a includes a smooth rod and its radial dimension is smaller than that of the second mounting hole 121. The second rod segment 211b includes a screw and can be threadedly connected to the hole walls of the first mounting hole 113 and the second mounting hole 121.
[0105] One embodiment of this application provides a cable fixing device 100, which, through the above-described configuration, can also meet the relative position adjustment requirements between the first clamping part 11 and the second clamping part 12 to accommodate the clamping and fixing of cables with different radial dimensions. Simultaneously, the above configuration allows the first connecting rod 211 to be threadedly connected to the second clamping part 12 when separated from the first clamping part 11, thus fixing the first connecting rod 211 to the second clamping part 12 and reducing the risk of the first connecting rod 211 falling or being lost.
[0106] In some alternative embodiments, the second connector 22 includes a second connecting rod 221 and a second locking cap 222. The second connector 22 is inserted into and protrudes from the first clamping portion 11. The second locking cap 222 is disposed on the side of the first clamping portion 11 opposite to the second clamping portion 12 and is detachably connected to the second connecting rod 221.
[0107] The second connecting rod 221 may optionally include a screw with an end cap, and the second locking cap 222 may optionally include a nut. The second connecting rod 221 and the second locking cap 222 may be connected by a threaded connection. Of course, this is one optional embodiment. In some embodiments, the second connecting rod 221 and the second locking cap 222 may be detachably connected to each other by a snap-fit engagement, for example, one has a protrusion and the other has a buckle, with the protrusion extending into the buckle and being detachably connected to each other.
[0108] Please continue reading. Figures 3 to 12 As shown, in some optional embodiments, a cable fixing 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 are connected and form a clamping cavity 10a.
[0109] The cable fixing device 100 provided in one embodiment of this application, through the above-mentioned arrangement, enables the first clamping part 11 and the second clamping part 12 to provide limit 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 fixing.
[0110] Optionally, one of the first recess 101 and the second recess 102 includes a pair of first arc-shaped grooves 1011 and the other includes a second arc-shaped groove 1021. The center of the second arc-shaped groove 1021 is located on the axis of symmetry 30 of the pair of first arc-shaped grooves 1011, and the second direction Y intersects with the first direction X.
[0111] The center of the second arc-shaped groove 1021 is located on the axis of symmetry 30 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.
[0112] The cable fixing device 100 provided in one embodiment of this application, through the above-described arrangement, enables the first recess 101 and the second recess 102 to connect and form a clamping cavity 10a, in which the clamping cavity 10a can distribute the three cables aa in a triangular shape, ensuring the stability of clamping and fixing the cables aa.
[0113] In some optional embodiments, the cable fixing 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.
[0114] 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.
[0115] 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.
[0116] The cable fixing device 100 provided in one embodiment of this application, through the above-described configuration, can ensure the clamping and fixing requirements of each cable aa and ensure the reliability of the clamping and fixing.
[0117] In some optional embodiments, the cable fixing device 100 provided in one embodiment of this application further includes an anti-slip structure 40, which is disposed on at least one of the first clamping part 11 and the second clamping part 12 and protrudes toward the clamping cavity 10a.
[0118] 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.
[0119] The cable fixing 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.
[0120] 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.
[0121] 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.
[0122] 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.
[0123] As an example, the length of the anti-slip structure 40 in the first direction X may include, but is not limited to, 0.9mm, 0.95mm, 0.97mm, 1mm, etc.
[0124] 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 fixing device 100.
[0125] 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.
[0126] By setting multiple first anti-slip parts 41 and distributing them at intervals along the height direction Z, it is possible to better prevent the cable aa from shifting within the clamping cavity 10a. Furthermore, by integrally molding the first anti-slip parts 41 with the first clamping part 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 the cable aa, and thus improving the reliability of the cable fixing device 100.
[0127] 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.
[0128] 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.
[0129] 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.
[0130] 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 part 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 fixing device 100.
[0131] 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.
[0132] 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.
[0133] For example, the anti-slip structure 40 includes a plurality of first anti-slip parts 41 disposed on the first clamping part 11 and a plurality of second anti-slip parts 42 disposed on the second clamping part 12. The plurality of first anti-slip parts 41 are distributed at intervals along the height direction Z, and the first anti-slip parts 41 and the first clamping part 11 are an integral structure. The plurality of second anti-slip parts 42 are distributed at intervals along the height direction Z, and the second anti-slip parts 42 and the second clamping part 12 are an integral structure.
[0134] 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.
[0135] Continue reading Figures 3 to 12 As shown, in some optional embodiments, the cable fixing 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 first clamping part 11 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.
[0136] 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 fixing device 100 on the cable aa, thereby improving the reliability of the cable aa fixing device.
[0137] 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 cable aa when it comes into contact with the cable aa.
[0138] In some alternative embodiments, the second clamping portion 12 is provided with anti-scratch portions 50 on both sides along the height direction Z.
[0139] Since the cable aa is laid along the height direction Z when the cable fixing device 100 is used, anti-scratch parts 50 are 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 parts 50 and avoid contact with the fixing part, thus preventing the cable aa from being scratched. It also helps to reduce processing difficulty and cost.
[0140] Please refer to the figure. Figures 9 to 12 In some optional embodiments, the anti-scratch portion 50 provided on the second clamping portion 12 may protrude from the end cap of the first connecting rod 211 along the first direction X, so as to reduce the probability of the end cap abrading the cable aa.
[0141] In some alternative embodiments, the cable fixing device 100 provided in one embodiment of this application has a limiting groove 123 provided on the side of the second clamping part 12 away from the first clamping part 11. The limiting groove 123 is provided corresponding to the end cap of the first connecting rod 211. The end cap is located in the limiting groove, which facilitates the installation and positioning of the end cap.
[0142] Optionally, the connecting assembly 20 may further include a gasket 213, which is sleeved on the first connecting rod 211 and abuts against the end cap of the first connecting rod 211 on the side facing the first clamping part 11 in the first direction X. The gasket 213 is disposed in the limiting groove 123 and engages with the second clamping part 12. With this arrangement, the gasket 213 can be pressed into the limiting groove 123 by the end cap of the first connecting rod 211, which helps to improve the connection strength between the gasket 213 and the second clamping part 12. In addition, it also facilitates the operation of the end cap of the first connecting rod 211 by the operator. For example, the end cap of the first connecting rod 211 can be screwed to move the end cap of the first connecting rod 211 in the first direction X.
[0143] Please see Figure 13 As shown, in some optional embodiments, the cable fixing device 100 provided in one embodiment of this application has a plurality of clamping cavities 10a and is distributed at intervals along the second direction Y. Each clamping cavity 10a is provided with a second connector 22. The second direction Y intersects with the first direction X.
[0144] The number of clamping cavities 10a can be two, three, or more, depending on the number of cables to be clamped. Each clamping cavity 10a is provided with a corresponding second connector 22.
[0145] One embodiment of this application provides a cable fixing device 100, which, through the above-described configuration, facilitates the simultaneous clamping and fixing of multiple sets of cables.
[0146] The tower 1 and wind turbine generator provided in some embodiments of this application, by including the cable fixing device 100 provided in the above embodiments, can ensure the fixing requirements of cable aa and ensure the reliability of operation.
[0147] 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.
