Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a cable clamp, a tower, and a wind turbine generator set. Background Technology

[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, and cannot be used for cables of different specifications at the same time. When the size of the cable varies greatly, the cable clamp cannot adapt to the clamping of the cable in time, which can easily lead to unstable clamping or failure to clamp. Therefore, it is necessary to replace the clamp to accommodate different types of cables, which increases the cost of the required clamp. Utility Model Content

[0034] 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.

[0035] 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.

[0036] To better understand this utility model, the following is in conjunction with... Figures 1 to 6 The cable clamp, tower, and wind turbine generator set of the present invention are described in detail below.

[0037] 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 raising assembly 30. The clamping assembly 10 includes a first clamping part 11 and a second clamping part 12 distributed along a first direction X, and a clamping cavity 13 is formed between the first clamping part 11 and the second clamping part 12. The connecting assembly 20 is connected to the first clamping part 11 and the second clamping part 12 and enables the relative distance between the first clamping part 11 and the second clamping part 12 in the first direction X to be adjustable. The raising assembly 30 is disposed between the first clamping part 11 and the second clamping part 12 and is detachably connected to the clamping assembly 10.

[0038] 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 100 can also be used in towers and serve as a component of the tower.

[0039] 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.

[0040] 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.

[0041] 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, making the size of the clamping cavity 13 adjustable.

[0042] 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.

[0043] In this embodiment, the size of the clamping cavity 13 can be adjusted in the manner described above. However, when the cable size range is large, the size of the clamping cavity 13 needs to be significantly increased. Therefore, in this embodiment, a shim assembly 30 is provided and placed between the first clamping part 11 and the second clamping part 12, thereby significantly increasing the size range of the clamping cavity 13 to meet the clamping requirements of large-size cables.

[0044] Optionally, the shim assembly 30 can be a block structure. Before adjusting the size of the clamping cavity 13 using the connecting assembly 20, the shim assembly 30 needs to be set on the first clamping part 11 or the second clamping part 12, and then the distance between the two needs to be adjusted. The shim assembly 30 needs to be detachably connected to the clamping part so that it can be disassembled and adjusted.

[0045] It is understood that there are various ways to detachably connect the shimming component 30 and the clamping component 10. This application does not impose any special limitation on the specific connection method, as long as it can ensure that the two are detachable. Any detachable connection method is within the protection scope of this application.

[0046] This utility model provides a cable clamp 100. By setting a shim assembly 30 between the first clamping part 11 and the second clamping part 12 of the cable clamp 100, the distance between the first clamping part 11 and the second clamping part 12 is expanded by utilizing the height of the shim assembly 30 itself, thereby increasing the size of the clamping cavity 13 between them. This completes the size adjustment of the intermediate clamping cavity 13, thus meeting the clamping requirements of larger cables. At the same time, the shim assembly 30 and the clamping assembly 10 are detachably connected, which facilitates the disassembly and replacement of the shim assembly 30 by the staff. By utilizing the characteristic that different shim assemblies 30 have different heights, the distance between the first clamping part 11 and the second clamping part 12 can be adjusted to increase the height, so that the clamping cavity 13 has multiple size adjustment options, meeting more diverse cable clamping requirements and having better applicability.

[0047] As an optional embodiment, the number of the shim components 30 includes multiple sets, each set of shim components 30 being detachably connected to the clamping component 10, and at least two sets of shim components 30 having different thicknesses in the first direction X.

[0048] In this embodiment, multiple sets of shim components 30 are provided. For example, as shown in the figure, each set of shim components 30 is provided with two shim pieces 31 and the two shim pieces 31 have the same thickness. However, the thicknesses of the shim components 30 in different sets are different. When shim components 30 of different thicknesses are detachably disposed between the first clamping part 11 and the second clamping part 12, the clamping cavity 13 can form spaces of different sizes, which has the versatility after adjustment.

[0049] In other words, when it is necessary to adjust the size of the clamping cavity 13, one set of the shim assembly 30 of different thicknesses can be removed and replaced with another set of shim assemblies 30 of different thicknesses, thereby adjusting the distance between the first clamping part 11 and the second clamping part 12, and thus completing the size adjustment of the clamping cavity 13.

[0050] Workers can select the appropriate height of the shim assembly 30 based on the actual cable size to install between the clamping assemblies 10, thereby accommodating the corresponding cable size. This application does not impose a special limit on the number of shim assemblies 30, which can be determined based on the actual cable size to be fixed, and the height of different shim assemblies 30 can be set to different values.

[0051] This utility model provides a cable clamp 100. By setting multiple sets of shim components 30, each set having a different height, and detachably connecting different sets of shim components 30 between clamping components 10, the clamping cavity 13 can be adjusted in a variety of ways to meet the clamping needs of more types of cables.

[0052] As an optional embodiment, please refer to Figure 1 Each set of elevation components 30 includes multiple elevation elements 31, each elevation element 31 being detachably connected to the clamping component 10, and each elevation element 31 in the same set of elevation components 30 having the same thickness dimension in the first direction X.

[0053] As shown in the figure, the shim assembly 30 can be configured as a combination of two shims 31. The two shims 31 are placed on both sides of the clamping cavity 13. Before adjusting the size of the clamping cavity 13, the two shims 31 can be installed simultaneously between the first clamping part 11 and the second clamping part 12, which is beneficial to the structural balance during the adjustment process.

[0054] Optionally, the shim 31 can be a block structure and the two shims 31 have the same thickness. In this embodiment, the shim assembly 30 is set in the first clamping part 11 as an example. First, the two shims 31 are installed at the two ends of the first clamping part 11. Then, the connecting assembly 20 is used to drive the second clamping part 12 to move in the first direction X and gradually approach the first clamping part 11 until it abuts against the cable in the clamping cavity 13 to complete the fixing process. The shims 31 on both sides limit the movement range of the second clamping part 12, so that the clamping cavity 13 in the middle has a larger size, which meets the clamping requirements of large-sized cables.

[0055] When a significant adjustment to the size of the clamping cavity 13 is required, it is only necessary to remove the aforementioned set of shim components 30 and install another set of shim components 30 with different thicknesses, thereby enabling the clamping cavity 13 to obtain another size range to accommodate cable fixing requirements of another size.

[0056] This utility model provides a cable clamp 100. By setting the shim assembly 30 into a structure of multiple shim pieces 31, the size of the clamping cavity 13 is adjusted, which is beneficial to the overall balance and stability of the structure, thereby improving the stability of cable clamping and reducing the risk of fixation failure.

[0057] As an optional embodiment, please refer to Figure 2 and Figure 4 The clamping assembly 10 and the shim 31 are provided with a slot 14 on one and a snap-fit ​​protrusion 31b on the other. The shape of the snap-fit ​​protrusion 31b matches the shape of the slot 14 and they are connected to each other.

[0058] This embodiment provides a connection method between the shim 31 and the clamping assembly 10. Specifically, a slot 14 is provided on one of them and a snap-fit ​​protrusion 31b is provided on the other. The slot 14 and the snap-fit ​​protrusion 31b are interlocked to achieve a detachable connection.

[0059] It is understood that the shape and structure of the card slot 14 and the card engagement protrusion 31b are matched to ensure that the two can be smoothly inserted. This application does not make any special limitation on the specific structure of the two.

[0060] When it is necessary to set up a set of shim components 30, the shim component 31 is inserted into the slot 14 of the first clamping part 11 through its own snap-fit ​​protrusion 31b, thereby completing the connection process. When it is necessary to adjust the size of the clamping cavity 13, the shim component 31 is removed and replaced with another set of shim components 31 of different thicknesses, which is then inserted into the first clamping part 11 to adjust the spacing between the clamping components 10, thereby completing the size adjustment of the clamping cavity 13.

[0061] This utility model provides a cable clamp 100, which provides a feasible plug-in connection method by utilizing the structure of the slot 14 and the snap-fit ​​protrusion 31b to cooperate with each other. This facilitates the staff to quickly adjust the size of the clamping cavity 13, has better convenience, and improves the overall adjustment efficiency of the clamp.

[0062] As an optional embodiment, please refer to Figure 4At least one of the first clamping part 11 and the second clamping part 12 is provided with a slot 14. The opening of the slot 14 faces the shim 31 and extends in the first direction X. The shim 31 includes a body part 31a and a snap-fit ​​protrusion 31b. The snap-fit ​​protrusion 31b protrudes from the body part 31a in the first direction X.

[0063] Optionally, as shown in the figure, this embodiment uses the example of setting the card slot 14 on the first clamping part 11 and setting the snap-fit ​​protrusion 31b on the padding part 31 for illustration.

[0064] The shim 31 specifically includes a body part 31a and a snap-fit ​​protrusion 31b. Optionally, the body part 31a and the snap-fit ​​protrusion 31b can be integrally formed by a casting process, which facilitates the preparation of the shim 31. The snap-fit ​​protrusion 31b can be extended protruding along the first direction X, so that the snap-fit ​​protrusion 31b can be inserted into the slot 14 in the first direction X.

[0065] This utility model embodiment provides a cable clamp 100. By setting the shim 31 as a structure of body 31a and snap-fit ​​protrusion 31b, the shim 31 can be detachably connected by using the snap-fit ​​protrusion 31b and the slot 14 for insertion and engagement. This facilitates the insertion and connection of the shim 31 by the operator and reduces the difficulty of adjustment.

[0066] As an optional embodiment, please refer to Figure 4 The first clamping part 11 includes an intersecting first surface 1 and a second surface 2. The first surface 1 is opposite to the second clamping part 12 in the first direction X. The slot 14 is disposed at the connection between the first surface 1 and the second surface 2. The slot 14 has a communicating first opening 3 and a second opening 4. The first opening 3 is located on the first surface 1 and the second opening 4 is located on the second surface 2.

[0067] Optionally, regarding the position of the slot 14 on the first clamping part 11, in this embodiment it is set at the junction of the first surface 1 and the second surface 2, so that the slot 14 has a first opening 3 and a second opening 4, with the two openings located on the two surfaces respectively.

[0068] If both the first opening 3 and the second opening 4 are set as rectangular opening structures, then the snap-fit ​​protrusion 31b is set as a corresponding rectangular block structure. The snap-fit ​​protrusion 31b can easily be inserted into the slot 14 from the position of the first opening 3 or the second opening 4.

[0069] This utility model provides a cable clamp 100. By setting the slot 14 to have a first opening 3 and a second opening 4, the locking protrusion 31b can be selectively inserted from the first opening 3 and the second opening 4, which improves the convenience of inserting the shim 31 and also facilitates the disassembly process of the shim 31.

[0070] As an optional embodiment, please refer to Figure 4 The slot 14 includes a tapered groove along the first direction X and pointing from the second clamping part 12 to the first clamping part 11. The width of the slot 14 gradually increases in the second direction Y. The first direction X intersects the second direction Y.

[0071] Optionally, in this embodiment, the slot 14 is configured as a conical slot, that is, a dovetail slot, so that it gradually approaches one side of the second clamping part 12 along the first direction X. The width of the conical slot in the second direction Y becomes smaller and smaller. When the locking protrusion 31b is inserted into the slot 14, it restricts the movement of the shim 31 in the first direction X, so that the shim 31 can only be disassembled and assembled in one direction, and has a better fixing ability for the shim 31.

[0072] It is understandable that the structure of the snap-fit ​​protrusion 31b corresponding to the snap-fit ​​groove 14 is also set as a conical structure, and its two bottom corners form a snap-fit ​​with the conical groove, thereby restricting the movement of the shim 31 in the first direction X. The shim 31 can complete the insertion connection process through the second opening 4.

[0073] This utility model embodiment provides a cable clamp 100. By setting the slot 14 as a conical groove structure, it gradually approaches one side of the second clamping part 12 along the first direction X. The width of the conical groove gradually decreases in the second direction Y, thereby better restricting the movement of the shim 31 in the first direction X after insertion, reducing the degree of freedom of movement of the shim 31 after insertion, so that the overall structure has better adjustment stability, and the clamping cavity 13 can form a stable dimensional state.

[0074] 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 15, and each connector 21 is movably inserted into a set of connecting holes 15.

[0075] Optionally, alignment connection holes 15 can be provided on both sides of the clamping cavity 13. For example, two sets of connection holes 15 are provided on both sides of the clamping cavity 13 in the figure. The connection holes 15 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 15. This application does not impose a special limit on the number of connectors 21, which can be determined according to the connection requirements.

[0076] 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.

[0077] 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.

[0078] Optionally, when the connecting hole 15 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 15. If the connecting hole 15 is configured as a blind hole, the connector 21 inserted into the connecting hole 15 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.

[0079] This utility model provides a cable clamp 100. By setting multiple sets of connection holes 15 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.

[0080] As an optional embodiment, please refer to Figure 5 and Figure 6 The shim assembly 30 is provided with a relief groove 31c that runs through the first direction X. The orthographic projection of the connecting hole 15 in the first direction X is located within the orthographic projection of the relief groove 31c. The connector 21 is inserted into the relief groove 31c.

[0081] When the shim assembly 30 is placed between the clamping assemblies 10 to complete the size adjustment of the clamping cavity 13, the distance between the first clamping part 11 and the second clamping part 12 is further adjusted using the connector 21. At this time, the connector 21 needs to be inserted into the aligned connecting hole 15, and the added shim assembly 30 needs to pass through it. Therefore, in this embodiment, a clearance groove 31c corresponding to the connecting hole 15 needs to be provided at the corresponding position of the shim assembly 30.

[0082] As the connector 21 is gradually inserted into the connection hole 15, the connector 21 will also pass through the relief groove 31c at the shim 30, thus completing the connection between the clamping component 10 and the shim 30. Optionally, the relief groove 31c needs to be set to be larger than the opening size of the connection hole 15, so as to ensure that the connector 21 can pass smoothly through the relief groove 31c to complete the connection with the shim 30.

[0083] This application does not impose any special limitations on the specific shape and size of the clearance groove 31c, as long as it can pass through in the first direction X and be set in accordance with the connection hole 15, so as to ensure the smooth insertion of the connector 21 during the adjustment process.

[0084] This utility model provides a cable clamp 100. By setting a relief groove 31c on the shim 30 corresponding to the connection hole 15, the connector 21 can be smoothly inserted into the shim 30. In addition to using the shim 30 to adjust the size of the clamping cavity 13, the connector 21 can also be used to improve the stability of the connection between the clamping component 10 and the shim 30, resulting in higher structural strength.

[0085] As an optional embodiment, please refer to Figure 5 and Figure 6 The shim assembly 30 has a side wall surrounding the connector 21, and a clearance groove 31c is provided through the side wall.

[0086] In this embodiment, based on the provision of a relief groove 31c to the shim assembly 30, the relief groove 31c is further made to penetrate through the side wall of the shim assembly 31 to which it is located. Optionally, the relief groove 31c can be a U-shaped groove structure.

[0087] The purpose of extending the relief groove 31c through the side wall is to facilitate the connection of the shim 31. Specifically, after adjusting the distance between the first clamping cavity 13 and the second clamping cavity 13 using the connector 21, if you want to significantly increase the size of the clamping cavity 13, you do not need to remove the connector 21. Instead, you can directly insert the relief groove 31c of the shim 31 into the connector 21 to raise the clamping assembly 10, or replace the middle shim 31, which facilitates the quick assembly and disassembly of the shim 31.

[0088] This utility model embodiment provides a cable clamp 100, which, by penetrating the side wall of the relief groove 31c, can form a plug-in fixation by utilizing the corresponding connection hole 15 of the relief groove 31c, and can also enable the shim 31 to be quickly replaced and disassembled through the relief groove 31c, reducing the disassembly and assembly steps of the connector 21 and improving the replacement efficiency of the shim 31.

[0089] As an optional embodiment, the first clamping part 11 has a first recess 16, and the second clamping part 12 has a second recess 17. The openings of the first recess 16 and the second recess 17 are arranged opposite to each other in the first direction X to enclose and form a clamping cavity 13.

[0090] 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 16 and the second recess 17 being formed relative to each other. Adjusting the size of the clamping cavity 13 is actually adjusting the distance between the first recess 16 and the second recess 17.

[0091] This application does not impose any special limitations on the specific structure of the first recess 16 and the second recess 17. The function of the two recesses is to accommodate the cable to be fixed. Therefore, the actual structure of the first recess 16 and the second recess 17 needs to be determined according to the actual cable profile so that the clamping cavity 13 can make sufficient contact and fix the cable.

[0092] This utility model provides a cable clamp 100, which forms a clamping cavity 13 by utilizing a first recess 16 and a second recess 17 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.

[0093] As an optional embodiment, the first recess 16 includes two successively disposed first arcuate grooves 16a, and the second recess 17 includes a second arcuate groove 17a, the orthographic projection of the second arcuate groove 17a in the first direction X covering at least a portion of the orthographic projection of the two first arcuate grooves 16a.

[0094] In this embodiment, the first recess 16 is configured as two first arc-shaped grooves 16a, and the second recess 17 is configured as a second arc-shaped groove 17a, so that the two first arc-shaped grooves 16a and one second arc-shaped groove 17a are correspondingly arranged in the first direction X, thereby forming a complete clamping cavity 13 structure.

[0095] 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.

[0096] Optionally, the height of both sides of the two first arc-shaped grooves 16a 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.

[0097] 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.

[0098] 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 inside the tower body; the first clamping part 11 is connected to the adapter frame.

[0099] 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.

[0100] According to an embodiment of the present invention, a wind turbine generator set is provided, including the tower as described above.

[0101] This utility model provides a cable clamp, a tower, and a wind turbine generator. By setting a shim component between the first and second clamping parts of the cable clamp, the distance between the first and second clamping parts is expanded using the height of the shim component itself. This increases the size of the clamping cavity between them, thus allowing for size adjustment of the intermediate clamping cavity and meeting the clamping requirements of larger cables. Furthermore, the shim component and the clamping component are detachably connected, facilitating easy disassembly and replacement by operators. Utilizing the different heights of different shim components, the distance between the first and second clamping parts can be adjusted to provide multiple size options for the clamping cavity, meeting more diverse cable clamping needs and offering better applicability.

[0102] 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.
