[0002] Cables are one of the most widely used materials in the power industry, enabling the transmission of energy and data. In wind turbine generators, components at the base of the tower are often connected to components at the top of the tower by cables and secured using cable clamps.

[0003] Existing cable clamps can only hold cables of one diameter, making them unsuitable for cables of different specifications. Furthermore, during the process of fixing cables with cable clamps, the cables are prone to shifting under pressure, leading to cable fixation failure. Summary of the Invention

[0004] This utility model provides a cable clamp, a tower, and a wind turbine generator set, which can further improve the binding ability of cables of different specifications and make them have better clamping stability.

[0005] In a first aspect, according to an embodiment of the present invention, a cable clamp is provided, including a clamping assembly, a connecting assembly, and a limiting protrusion. The clamping assembly includes a first clamping portion and a second clamping portion distributed along a first direction, and a clamping cavity is formed between the first clamping portion and the second clamping portion. The connecting assembly is connected to the first clamping portion and the second clamping portion and enables the relative distance between the first clamping portion and the second clamping portion in the first direction to be adjustable. The limiting protrusion is at least partially disposed between the first clamping portion and the second clamping portion. Along the first direction, at least one of the first clamping portion and the second clamping portion is connected to the limiting protrusion on the side facing the other. The limiting protrusion is located on the side of the connecting assembly near the clamping cavity.

[0006] According to one aspect of the present invention, the limiting protrusions are arranged in pairs, and the paired limiting protrusions are distributed opposite to each other on both sides of the clamping cavity.

[0007] According to one aspect of the present invention, the limiting protrusion extends along the first direction and has a first end and a second end opposite to each other, the first end being connected to the first clamping portion and the second end being disposed in contact with the second clamping portion.

[0008] According to one aspect of the present invention, the second clamping part is provided with a limiting hole, the limiting protrusion and the limiting hole are aligned in the first direction and the second end of the limiting protrusion can be inserted into the limiting hole.

[0009] According to one aspect of the present utility model, the limiting hole includes a blind hole, the limiting hole starting from one end face of the second clamping part toward the first clamping part and recessed toward the side away from the first clamping part;

[0010] Alternatively, the limiting hole may include a through hole penetrating the second clamping portion.

[0011] According to one aspect of the present invention, the limiting hole is polygonal when projected orthographically in the first direction, and the shape of the limiting protrusion matches the shape of the limiting hole and is clearance-fitted with the limiting hole.

[0012] According to one aspect of the present invention, the coefficient of friction of the surface of the limiting protrusion facing the clamping cavity is less than the coefficient of friction of the other surfaces.

[0013] According to one aspect of the present invention, the end of the limiting protrusion facing away from the connected clamping part is provided as a rounded corner surface.

[0014] According to one aspect of the present invention, the first clamping portion has a first recess and the second clamping portion has a second recess, the openings of the first recess and the openings of the second recess are disposed opposite to each other in the first direction to enclose and form the clamping cavity.

[0015] According to one aspect of the present invention, the first recess includes two successively disposed first arc-shaped grooves, the second recess includes a second arc-shaped groove, and the orthographic projection of the second arc-shaped groove in the first direction covers at least a portion of the orthographic projection of the two first arc-shaped grooves.

[0016] According to one aspect of the present invention, the connecting assembly includes a plurality of connectors, the first clamping portion and the second clamping portion having a plurality of sets of aligned connecting holes, and each connector being movably inserted into a set of the connecting holes.

[0017] Secondly, according to an embodiment of the present invention, a tower is provided, including a tower body, an adapter frame, and a cable clamp as described above, wherein the adapter frame is connected to the tower body; and the first clamping part is connected to the adapter frame.

[0018] Thirdly, according to an embodiment of the present invention, a wind turbine generator set is provided, including the tower as described above.

By setting a limiting protrusion between the first clamping part and the second clamping part of the cable clamp, and movably connecting the two parts through a connecting component to adjust the distance between them, the cable clamp can accommodate cables of different sizes during the fixing process. Furthermore, the limiting protrusion can limit the cable in the clamping cavity. The limiting protrusion abuts against the cable in the clamping cavity, preventing the squeezed cable from detaching from the clamping cavity during the adjustment of the distance between the first and second clamping parts. The limiting protrusion acts as a barrier, better confining the cable within the clamping cavity for fixing. Thus, while adjusting the size of the clamping cavity to accommodate different cable models, it improves the fixing ability of the cable in the clamping cavity, providing a more stable clamping and fixing effect.

[0028] 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.

[0029] 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 clamp, 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.

[0030] To better understand this utility model, the following is in conjunction with... Figures 1 to 3 The cable clamp, tower, and wind turbine generator set of the present invention are described in detail below.

[0031] Please see Figures 1 to 3 According to an embodiment of the present invention, a cable clamp 100 is provided, including a clamping assembly 10, a connecting assembly 20, and a limiting protrusion 30. The clamping assembly 10 includes a first clamping portion 11 and a second clamping portion 12 distributed along a first direction X, and a clamping cavity 13 is formed between the first clamping portion 11 and the second clamping portion 12. The connecting assembly 20 is connected to the first clamping portion 11 and the second clamping portion 12 and enables the relative distance between the first clamping portion 11 and the second clamping portion 12 in the first direction X to be adjustable. The limiting protrusion 30 is at least partially disposed between the first clamping portion 11 and the second clamping portion 12. Along the first direction X, at least one of the first clamping portion 11 and the second clamping portion 12 is connected to the side facing the other. The limiting protrusion 30 is located on the side of the connecting assembly 20 near the clamping cavity 13.

[0032] The cable clamp 100 provided in this application embodiment can be manufactured and sold separately as an independent component, and is suitable for various cable installation environments. At the same time, the cable clamp can also be used in towers and serve as a component of the tower.

[0033] Optionally, the first clamping part 11 and the second clamping part 12 can adopt a clamping plate structure to clamp the cable. The cable can be a power cable or an optical cable, etc., and can be applied to technical fields such as wind power generation, or other technical fields. This application does not make any special limitation on the specific type of cable, the technical field applied, or the specific structural form of the clamping assembly 10, as long as it can be able to enclose and form the above-mentioned clamping cavity 13 to accommodate the cable.

[0034] The specific structure of the clamping cavity 13 needs to be determined based on the actual number, type and outline of the cables to be fixed, to ensure that the first clamping part 11 and the second clamping part 12 at the clamping cavity 13 can make full contact with the cables to achieve a better fixing effect. This application does not make any special limitations on the specific structure and size of the clamping cavity 13.

[0035] In this embodiment, the clamping component 10 is connected by a connecting component 20. The connecting component 20 is connected between the first clamping part 11 and the second clamping part 12 and can move relative to both, forming a movable connection with both. This allows one of the first clamping part 11 and the second clamping part 12 to move relative to the other in the first direction X, ultimately adjusting the range of the clamping cavity 13 between the two, so that the size of the clamping cavity 13 is adjustable.

[0036] Optionally, the connecting component 20 can adopt a bolt structure, and the connecting component 20 and the clamping component 10 can form a threaded connection, so that the connecting component 20 can move relative to the clamping component 10 through the thread. During the rotation and tightening of the bolt, the second clamping part 12 can be driven to move toward or away from the first clamping part 11 to complete the spacing adjustment between the two, which is suitable for fixing cables of different diameters.

[0037] Based on this embodiment, a limiting protrusion 30 is provided between the first clamping part 11 and the second clamping part 12. Optionally, the limiting protrusion 30 can be a protrusion structure. This is mainly because when the connecting component 20 completes the above-mentioned size adjustment of the clamping cavity 13, the cable in the clamping cavity 13 may be squeezed and gradually squeezed out of the clamping cavity 13, thereby affecting the fixing effect of the clamping component 10 on the cable.

[0038] Therefore, a limiting protrusion 30 is provided between the first clamping part 11 and the second clamping part 12, so that the limiting protrusion 30 is located on the side closer to the clamping cavity 13. When the cable is gradually squeezed out, the limiting protrusion 30 can directly contact the cable to block the cable and ensure that the cable is restricted in the clamping cavity 13 to form a stable fixing effect.

[0039] Regarding the location of the limiting protrusion 30, it can be set on the first clamping part 11 or the second clamping part 12, or it can be set on both and abut against each other. This application is not limited in this regard, as long as it is located between the two and close to the clamping cavity 13.

[0040] Optionally, the clamping component 10 can be made of aluminum alloy by gravity die casting or nylon by die casting. This application does not impose any special limitations on its material and molding process. The limiting protrusion 30 can be integrally formed therein. The figures in this embodiment are all illustrated with the example of the limiting protrusion 30 being set in the first clamping part 11 and clamping and limiting three cables, but it is not limited to this setting method.

[0041] This utility model provides a cable clamp 100. By setting a limiting protrusion 30 between the first clamping part 11 and the second clamping part 12 of the cable clamp 100, and movably connecting the two through a connecting component 20 to adjust the distance between them, the cable clamp 100 can adapt to cables of different sizes during the fixing process. It can also limit the cable in the clamping cavity 13 by using the limiting protrusion 30. The limiting protrusion 30 abuts against the cable in the clamping cavity 13 to prevent the squeezed cable from falling out of the clamping cavity 13 during the adjustment of the distance between the first clamping part 11 and the second clamping part 12. The limiting protrusion 30 can block the cable to better restrict the cable in the clamping cavity 13 for fixing. Thus, while adjusting the size of the clamping cavity 13 to adapt to different types of cables, it improves the fixing ability of the cable in the clamping cavity 13 and has a more stable clamping and fixing effect on the cable.

[0042] As an optional embodiment, please refer to Figure 1 and Figure 2 The limiting protrusions 30 are arranged in pairs, and the paired limiting protrusions 30 are distributed on both sides of the clamping cavity 13.

[0043] When multiple cables are fixed in the clamping cavity 13, such as when three cables are fixed in the figure, during the process of adjusting the size of the clamping cavity 13 and squeezing the cables, the two cables at the bottom may overflow to both sides of the clamping cavity 13 at the same time. Therefore, in this embodiment, limiting protrusions 30 are set on both sides of the clamping cavity 13 to complete the blocking.

[0044] Based on this, setting limiting protrusions 30 on both sides of the clamping cavity 13 is also beneficial to improving the structural stability after clamping, so that the overall structure has better balance. Optionally, the paired limiting protrusions 30 are symmetrically distributed with the clamping cavity 13 as the center.

[0045] This utility model provides a cable clamp 100, which can simultaneously block cables in two directions by setting a pair of limiting protrusions 30 on both sides of the clamping cavity 13, thereby improving the limiting ability of the cables, meeting the needs of clamping and fixing multiple cables, and improving the overall balance and stability of the structure.

[0046] As an optional embodiment, the limiting protrusion 30 extends along the first direction X and has a first end and a second end opposite to each other, the first end being connected to the first clamping part 11 and the second end being in contact with the second clamping part 12.

[0047] The height of the limiting protrusion 30 in the first direction X can be determined according to the actual size of the fixed cable. The limiting protrusion 30 is connected to the first clamping part 11 through the first end. In this embodiment, after the cable is fixed by the first clamping part 11 and the second clamping part 12, the second end of the limiting protrusion 30 abuts against the second clamping part 12.

[0048] Of course, when the cable size is large, the distance between the first clamping part 11 and the second clamping part 12 is large. The limiting protrusion 30 can restrict the movement of the cable in the clamping cavity 13. At the same time, it is also possible that the limiting protrusion 30 and the second clamping part 12 are spaced apart and do not make contact. This needs to be determined according to the actual cable size.

[0049] This utility model provides a cable clamp 100, which uses a limiting protrusion 30 to restrict the cable in the clamping cavity 13, and the second end of the limiting protrusion 30 can abut against the second clamping part 12, thereby forming a stable support for the first clamping part 11 and the second clamping part 12, improving the overall structural stability of the clamping assembly 10, and providing a reliable guarantee for the stable fixing of the cable.

[0050] As an optional embodiment, please refer to Figure 1 The second clamping part 12 is provided with a limiting hole 40. The limiting protrusion 30 is aligned with the limiting hole 40 in the first direction X, and the second end of the limiting protrusion 30 can be inserted into the limiting hole 40.

[0051] Optionally, a limiting hole 40 is provided at the corresponding position of the limiting protrusion 30 on the second clamping part 12. On the basis of the limiting protrusion 30 abutting against the second clamping part 12, the limiting protrusion 30 can also be inserted into the limiting hole 40, thereby further improving the connection stability of the first clamping part 11 and the second clamping part 12.

[0052] It is understood that the shape of the limiting hole 40 provided on the second clamping part 12 needs to match the structure of the limiting protrusion 30 so as to ensure that the limiting protrusion 30 can be smoothly inserted into the limiting hole 40 when it abuts. This application does not make any special limitation on the specific shape of the limiting hole 40, as long as it can match the structure of the limiting protrusion 30.

[0053] When adjusting the distance between the first clamping part 11 and the second clamping part 12, if the cable in the clamping cavity 13 is squeezed and comes into contact with the limiting protrusion 30, since the limiting protrusion 30 is inserted into the limiting hole 40 at this time, it can form a sufficient blocking force on the cable, ensuring that there will be no relative displacement between the structures and causing fixation failure.

[0054] This utility model provides a cable clamp 100. By providing a limiting hole 40 corresponding to the limiting protrusion 30 on the second clamping part 12, the limiting protrusion 30 and the limiting hole 40 are connected. While blocking the cable with the limiting protrusion 30, the stability of the clamping assembly 10 connection is further improved, and the cable in the clamping cavity 13 is better restricted.

[0055] As an optional embodiment, the limiting hole 40 includes a blind hole, which starts from one end face of the second clamping part 12 toward the first clamping part 11 and is recessed toward the side opposite to the first clamping part 11; or, the limiting hole 40 includes a through hole that passes through the second clamping part 12.

[0056] Optionally, depending on the size of the actual fixed cable, the limiting protrusion 30 has different heights. Therefore, the contact depth between the limiting protrusion 30 and the second clamping part 12 is different. For example, the limiting hole 40 can be set as a blind hole structure. When adjusting the spacing of the clamping assembly 10, the limiting protrusion 30 can be inserted into the blind hole to complete the connection.

[0057] Of course, if the cable size in the clamping cavity 13 is small, the distance between the second clamping part 12 and the first clamping part 11 will decrease accordingly. At this time, the limiting hole 40 can be set as a through hole. The limiting hole 40 shown in the figure is a through hole structure. The limiting protrusion 30 can pass directly through the through hole to make the clamping assembly 10 connected. Under the action of the through hole, the limiting protrusion 30 will not undergo relative displacement, thus having a more stable blocking ability for the cable.

[0058] This utility model embodiment provides a cable clamp 100, which provides two structural forms of limiting holes 40. It can be set as a blind hole or a through hole and form a plug-in fit with the limiting protrusion 30. While effectively restricting the cable, it improves the stability of the connection of the clamping component 10 and reduces the risk of relative displacement between the two.

[0059] As an optional embodiment, please refer to Figure 1 The limiting hole 40 is polygonal when projected onto the first direction X. The shape of the limiting protrusion 30 matches the shape of the limiting hole 40 and is clearance-fitted with the limiting hole 40.

[0060] Optionally, in this embodiment, the limiting hole 40 can be set as a polygonal hole structure, as shown in the figure. It can be set as a rectangular hole structure, and the corresponding limiting protrusion 30 can be set as a rectangular block structure, so that the limiting protrusion 30 can be smoothly inserted into the limiting hole 40.

[0061] The purpose of setting the limiting hole 40 as a polygonal hole structure is to reduce the degree of freedom of the limiting protrusion 30 after insertion. Compared with setting the limiting hole 40 as a round hole, the polygonal hole can better restrict the degree of freedom of movement of the limiting protrusion 30, so that the limiting protrusion 30 can reduce its mobility after being inserted into the limiting hole 40, thus having better insertion stability.

[0062] Optionally, this application does not impose special limitations on the specific shape of the polygonal hole, as long as it can match the structure of the limiting protrusion 30 and form an interlocking fit. The figure uses a rectangular hole as an example for illustration. Of course, the limiting hole 40 can also be set as a circular hole according to actual processing requirements. Although a circular hole has a higher degree of freedom of movement, it can also play a limiting role for the limiting protrusion. This application does not impose special limitations on the hole shape of the limiting hole 40.

[0063] This utility model provides a cable clamp 100. By setting the limiting hole 40 as a polygonal hole and forming an insertion with the limiting protrusion 30, the connection stability of the clamping assembly 10 is improved, and the degree of freedom of movement of the limiting protrusion 30 is further restricted, thereby further improving the insertion stability of the limiting protrusion 30 and providing a guarantee for the reliable fixing and clamping of the cable.

[0064] As an optional embodiment, the coefficient of friction of the surface of the limiting protrusion 30 facing the clamping cavity 13 is less than the coefficient of friction of other surfaces.

[0065] Considering that the limiting protrusion 30 mainly serves to restrict the cable, and the cable will come into contact with the limiting protrusion 30 when it is squeezed out, in order to reduce the wear effect of the limiting protrusion 30 on the cable, this embodiment can reduce the friction coefficient of the contact surface between the limiting protrusion 30 and the cable, thereby reducing the frictional loss of the cable.

[0066] Optionally, the contact surface between the limiting protrusion 30 and the cable can be set as a smooth plane, which has a smaller coefficient of friction compared to other surfaces. This application does not impose special limitations on the specific value of the coefficient of friction. Smooth materials can be provided on the contact surface. This application does not impose special limitations on the specific measures, as long as the coefficient of friction of the contact surface is reduced.

[0067] This utility model provides a cable clamp 100, which reduces the coefficient of friction between the limiting protrusion 30 and the contact surface of the cable, thereby effectively restricting the movement of the cable, reducing wear on the cable, providing safety protection for the cable, and having higher safety protection performance.

[0068] As an optional embodiment, please refer to Figure 1 The end of the limiting protrusion 30 facing away from the connected clamping part is set as a rounded corner.

[0069] Considering that the limiting protrusion 30 may come into contact with the second clamping part 12, in order to protect the second clamping part 12 and prevent the limiting protrusion 30 from causing damage to it, in this embodiment the end of the limiting protrusion 30 is set as a rounded corner structure and the corner is rounded, so that the limiting protrusion 30 will not cause damage to the second clamping part 12 after it comes into contact with it.

[0070] This utility model embodiment provides a cable clamp 100. By setting the end of the limiting protrusion 30 as a rounded corner surface, the contact between the limiting protrusion 30 and the second clamping part 12 is smoother, which provides safer protection for the second clamping part 12, reduces the probability of damage between the two, and extends the service life of the components.

[0071] As an optional embodiment, please refer to Figure 1 and Figure 2 The first clamping part 11 has a first recess 14 and the second clamping part 12 has a second recess 15. The opening of the first recess 14 and the opening of the second recess 15 are arranged opposite to each other in the first direction X to form a clamping cavity 13.

[0072] In this embodiment, the clamping cavity 13 is formed by the first clamping part 11 and the second clamping part 12, specifically by the first recess 14 and the second recess 15 being formed relative to each other. Adjusting the size of the clamping cavity 13 is actually adjusting the distance between the first recess 14 and the second recess 15.

[0073] This application does not impose any special limitations on the specific structure of the first recess 14 and the second recess 15. The function of the two recesses is to accommodate the cable to be fixed. Therefore, the actual structure of the first recess 14 and the second recess 15 needs to be determined according to the actual cable profile so that the clamping cavity 13 can make sufficient contact and fix the cable.

[0074] This utility model provides a cable clamp 100, which forms a clamping cavity 13 by utilizing a first recess 14 and a second recess 15 in a relative manner. This provides a specific structural form of the clamping cavity 13, which better meets the requirements for fixing cables and provides an adaptive clamping space for cables of different sizes.

[0075] As an optional embodiment, please refer to Figure 2 The first recess 14 includes two successively arranged first arc-shaped grooves 14a, and the second recess 15 includes a second arc-shaped groove 15a. The orthographic projection of the second arc-shaped groove 15a in the first direction X covers at least a portion of the orthographic projection of the two first arc-shaped grooves 14a.

[0076] In this embodiment, the first recess 14 is configured as two first arc-shaped grooves 14a, and the second recess 15 is configured as a second arc-shaped groove 15a, so that the two first arc-shaped grooves 14a and one second arc-shaped groove 15a are correspondingly arranged in the first direction X, thereby forming a complete clamping cavity 13 structure.

[0077] The above embodiment satisfies the structural form of clamping three cables. Each arc-shaped groove can accommodate one cable, and the three cables are distributed in a triangular shape in the clamping cavity 13. This application does not make special limitations on the specific form of the recess, but can determine it according to the actual number of cables fixed.

[0078] Optionally, the height of both sides of the two first arc-shaped grooves 14a can be set to be greater than the height in the middle. So when the cable is laid in the clamping cavity 13 and fastened by the connector 21, the cable can be squeezed toward the center of the clamping cavity 13, so that the clamping assembly 10 can clamp the cable more tightly. By increasing the contact area between adjacent cables, the squeezing force between them is improved. Under the action of mutual squeezing force in the clamping cavity 13, the cable can be prevented from sliding down, ensuring the safety of the cable and thus improving the clamping reliability of the cable clamp 100.

[0079] This utility model provides a cable clamp 100, which, by setting the recess as an arc-shaped groove, can better adapt to the outer contour of the cable and accommodate a corresponding number of cables, thus better meeting the fixing requirements for cables of different quantities and sizes.

[0080] As an optional embodiment, the connecting assembly 20 includes a plurality of connectors 21, and the first clamping part 11 and the second clamping part 12 have a plurality of sets of aligned connecting holes 16, and each connector 21 is movably inserted into a set of connecting holes 16.

[0081] Optionally, alignment connection holes 16 can be provided on both sides of the clamping cavity 13. For example, two sets of connection holes 16 are provided on both sides of the clamping cavity 13 in the figure. The connection holes 16 can be bolt holes, and the connector 21 can be a bolt structure. The position of the clamping assembly 10 can be adjusted by movably inserting the connector 21 into the connection hole 16. This application does not impose a special limitation on the number of connectors 21, which can be determined according to the connection requirements.

[0082] With the above-mentioned threaded connection, when the connector 21 is screwed on, the second clamping part 12 will gradually move closer to or away from the first clamping part 11, thereby adjusting the size of the clamping cavity 13 between the two to accommodate different cable models. When screwing on the connector 21, multiple connectors 21 need to be adjusted simultaneously to ensure structural balance.

[0083] Optionally, when the connector 21 is configured as a bolt structure, the operator only needs to tighten the nut during adjustment, thereby driving the screw to move in the first direction X. In order to improve the stability of the above bolt connection, a shim can be provided between the connector 21 and the second clamping part 12. In addition to improving the bolt tightening force, it can also reduce the wear between the parts during the tightening process.

[0084] Optionally, when the connecting hole 16 is configured as a through hole, the connector 21 can be directly inserted into the fixed bracket of the tower using the through hole structure of the connecting hole 16. If the connecting hole 16 is configured as a blind hole, the connector 21 inserted into the connecting hole 16 only serves to adjust the size of the clamping cavity 13. A fixing hole needs to be provided on the first clamping part 11, and a fixing bolt needs to pass through the fixing hole so that the first clamping part 11 can be directly inserted into the tower using the fixing bolt. Both of the above methods can achieve the fixing of the cable clamp 100.

[0085] This utility model provides a cable clamp 100. By setting multiple sets of connection holes 16 on the clamping assembly 10 and using multiple connectors 21 for movable insertion, the size of the clamping cavity 13 can be adjusted, while ensuring the connection strength of the clamping assembly 10 and improving the overall structural stability of the clamp.

[0086] According to an embodiment of the present invention, a tower is provided, including a tower body, an adapter frame, and a cable clamp 100 as described above. The adapter frame is connected to the tower body; the first clamping part 11 is connected to the adapter frame.

[0087] Optionally, the cable clamp 100 in this embodiment can be applied in the field of wind power generation technology. Specifically, it can be connected to the tower, and the cable passing through the adapter frame can be clamped by the cable clamp 100 to fix the cable to the adapter frame of the tower.

[0088] According to an embodiment of the present invention, a wind turbine generator set is provided, including the tower as described above.

[0089] This utility model provides a cable clamp, a tower, and a wind turbine generator set. By setting a limiting protrusion between the first clamping part and the second clamping part of the cable clamp, and movably connecting the two parts through a connecting component to adjust the distance between them, the cable clamp can accommodate cables of different sizes during the fixing process. Furthermore, the limiting protrusion can limit the cable in the clamping cavity. The limiting protrusion abuts against the cable in the clamping cavity, preventing the squeezed cable from detaching from the clamping cavity during the adjustment of the distance between the first and second clamping parts. The limiting protrusion acts as a barrier, better confining the cable within the clamping cavity for fixing. Thus, while adjusting the size of the clamping cavity to accommodate different cable models, it improves the fixing ability of the cable in the clamping cavity, providing a more stable clamping and fixing effect.

[0090] 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.
