Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and in particular to a cable fixing device and a tower. Background Art

[0002] In wind turbines, power is primarily transmitted via cables, and typically these cables are routed and wired within the wind turbine's tower. The tower, the primary load-bearing structure, typically features a top platform, a bottom platform, and multiple intermediate platforms. Cables are routed from the wind turbine's nacelle, pass through the top platform, and then are installed within the tower. Currently, the typical method for installing cables within the tower is to run them to the inner wall of the tower, secure them at multiple intervals, and then route them into an electrical cabinet located on the bottom platform.

[0003] However, the above-mentioned cable installation structure and method require multiple welding points on the inner wall of the tower for installing the cables, which affects the structural strength of the tower. Moreover, when the wind turbine is running, the cable at the top of the tower needs to be twisted and swung with the cabin. This section of cable is generally called a twisted cable section, which needs to be suspended and then led to the inner wall of the tower for installation and fixation. This causes the cable to have a bend, and the cable needs to be lifted and pulled when installed. In addition, after long-term operation of the wind turbine and long-term use of the cable, this installation method may cause increased wear of the cable. Moreover, since the cable is in a suspended state for a long time, the core of the cable may also be damaged, affecting the service life of the cable. Summary of the Invention

Therefore, they should not be understood as limiting the scope of protection of the present disclosure.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical connections; direct connections or indirect connections via an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] Throughout this specification, references to the terms "embodiment," "one embodiment," and "an implementation" indicate that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.

[0040] In order to solve the above technical problems, Figures 1 to 5 、 Figure 11 and Figure 15As shown, an embodiment of the present invention provides a cable fixing device, including a limiting bracket 1, a fixing bracket 2 and a fixing assembly 3, the limiting bracket 1 is used to limit the cable 01, the fixing assembly 3 is used to be arranged on the fixing bracket 2, the limiting bracket 1 is located above the fixing bracket 2 and the fixing assembly 3, and a first through hole 11, a second through hole 21 and a third through hole 31 for the cable 01 to pass through are respectively provided on the limiting bracket 1, the fixing bracket 2 and the fixing assembly 3, the first through hole 11, the second through hole 21 and the third through hole 31 are correspondingly arranged along the height direction of the tower, so that the cable 01 passing through the first through hole 11, the second through hole 21 and the third through hole 31 at the same time is arranged vertically, and the third through hole 31 is used to fix the cable 01.

[0041] Specifically, the number of the limiting brackets 1, the fixing brackets 2 and the fixing components 3 are all set to be multiple, which can be determined according to the height of the tower. Moreover, it should be understood that in order to install and fix the cable 01, the tower top platform 8 and the intermediate platform 9 are both provided with holes for the cable 01 to pass through, and are arranged corresponding to the first through hole 11, the second through hole 21 and the third through hole 31 to ensure that the cable in the tower is installed and fixed vertically. A plurality of limiting brackets 1 are evenly spaced between the tower top platform 8 and the intermediate platform 9 located at the top of the tower, that is, the first one above in the figure, and the intermediate platform 9 is called a twisting platform. After the cable 01 is led out from the cabin of the wind turbine, it passes through the hole opened on the tower top platform 8, the first through hole 11 on the plurality of limiting brackets 1 and the hole opened on the twisting platform in turn, so as to tighten the cable 01. The twisted cable segment is segmented and limited to prevent excessive swinging, and a fixing component 3 can be set on the twisting platform. The third through hole 31 of the fixing component 3 can fix the cable 01, so that only the twisted cable segment cable 01 between the tower top platform 8 and the twisting platform in the tower can be twisted and swung. In addition, from the twisted cable platform to the bottom of the tower, between two adjacent intermediate platforms 9, that is, between the first intermediate platform 9 and the second intermediate platform 9 from top to bottom in the figure, and between the second and third intermediate platforms 9, and so on, multiple fixing brackets 2 can be evenly spaced and set in this interval, and fixing components 3 can be set on the intermediate platform 9 and the fixing bracket 2 respectively. The cable 01 is fixed by the segmented fixing components 3, ensuring the overall structural strength and stability. At the same time, the above-mentioned installation and fixing method replaces the existing installation method of adding multiple welding points on the inner wall of the tower to fix the cable 01, thereby improving the structural strength of the tower and also increasing the service life of the tower. It should be noted that the structure of the third through hole 31 of the fixing assembly 3 for fixing the cable 01 can be, for example, a clamping hole structure, that is, the cable 01 is installed and fixed by, for example, clamping and fixing. In addition, the hole for the cable 01 to pass through the tower top platform 8, the hole for the cable 01 to pass through the intermediate platform 9, the first through hole 11, the second through hole 21, and the third through hole 31 are all correspondingly arranged, for example, they can be arranged at the axis of the tower, or at a position offset from the axis. As long as the above-mentioned multiple holes are arranged correspondingly on a vertical line, no specific limitation is made here. The above-mentioned structural arrangement basically ensures the coaxiality of the above-mentioned multiple holes. Preferably, the first through hole 11, the second through hole 21, and the third through hole 31 are respectively arranged on the limiting bracket 1, the fixing bracket 2, and the middle of the fixing assembly 3, so that the above-mentioned through holes for the cable 01 to pass through or be fixed are all coaxially arranged at the axis position of the tower, thereby ensuring the verticality of the cable 01 in the tower and facilitating alignment and installation. Furthermore, it should be noted that the limiting bracket 1 , the fixing bracket 2 and the fixing assembly 3 can be arranged in different quantities and positions in the tower according to the actual shape, size and different application requirements of the tower.

[0042] In this embodiment, by setting a limit bracket 1, the limit bracket 1 can be connected to the inner wall of the tower of the wind turbine, and the limit bracket 1 can be installed between the tower top platform 8 and the intermediate platform 9 at the top of the tower. A plurality of limit brackets 1 can be set at intervals in this interval, and the cable 01 can pass through the hole opened on the tower top platform 8, and then pass through the first through hole 11 set on the limit bracket 1 to install the cable 01, which can effectively limit the cable 01 in this interval, that is, the twisted cable section, to prevent the cable 01 from twisting and swinging too much; at the same time, the fixed bracket 2 can be connected to the inner wall of the tower, and, for example, multiple fixed brackets 2 can be installed in sections and intervals between two adjacent intermediate platforms 9, and the cable 01 can pass through the second through hole 21 set on the fixed bracket 2. It should be understood here that the intermediate platform 9 also has corresponding holes for the cable 01 to pass through, and by separately placing multiple fixing components 3 The third through hole 31 provided on the fixing component 3, which is arranged on the fixing bracket 2 and the intermediate platform 9, can fix the cable 01 by clamping, so that the cable 01 below the twisted cable section in the tower is fixed in sections, effectively preventing the core of the cable 01 from being damaged due to excessive hanging, and preventing the cable 01 from swinging excessively, thereby effectively improving the stability of the cable 01 during installation; and, by respectively providing the first through hole 11, the second through hole 21 and the third through hole 31 on the limiting bracket 1, the fixing bracket 2 and the fixing component 3, and all being provided along the height direction of the tower, the cable 01 is vertically provided in the tower during and after installation, preventing the cable 01 from having a turning point, facilitating the pulling and installation of the cable 01, and thereby effectively preventing the cable 01 from having a bad stress point, preventing the cable 01 from being excessively worn during installation and use, and improving the service life and installation efficiency of the cable 01.

[0043] Alternatively, as Figure 3 As shown, the limiting bracket 1 includes a first frame 12 and a first mounting plate 13 . The first mounting plate 13 is disposed in the middle of the first frame 12 , and the first through hole 11 is opened in the middle of the first mounting plate 13 .

[0044] Specifically, the structure of the first frame 12 can be a "well"-shaped structure or an "H"-shaped structure, that is, it is ensured that the opposite ends of the first frame 12 can be connected to the inner wall of the tower. Under the premise of ensuring structural strength, the first through hole 11 can be located at the center of the tower to ensure that the entire cable 01 can be located at the center of the tower. On the one hand, the overall verticality of the cable 01 is guaranteed without a turning point. On the other hand, the cable 01 is close to the ladder in the tower, which is convenient for installation, maintenance and repair.

[0045] In this embodiment, by setting the limiting bracket 1 as the structural form of the first frame 12 and the first mounting plate 13, it is convenient for production and installation, and the strength of the structure is guaranteed, providing reliable protection for the installation and limiting of the cable 01, and the opposite ends of the first frame 12 can be connected to the inner wall of the tower respectively, and the first mounting plate 13 is set in the middle of the first frame 12, and by opening the first through hole 11 in the middle of the first mounting plate 13, the above structural setting also ensures that the first through hole 11 is located in the center of the tower, thereby facilitating the overall verticality of the cable 01 in the tower, avoiding the turning point of the cable 01, and ensuring the stability of the overall structure.

[0046] Alternatively, as Figure 4 As shown, the fixing bracket 2 includes a second frame 22 and a second mounting plate 23 , the second mounting plate 23 is arranged in the middle of the second frame 22 , the second through hole 21 is opened in the middle of the second mounting plate 23 , and the fixing component 3 is arranged on the second mounting plate 23 .

[0047] Specifically, the overall structure of the fixed bracket 2 can be set to be the same as that of the limiting bracket 1, that is, the structure of the second frame 22 can also be a "well"-shaped structure, or an "H"-shaped structure. Correspondingly, the structure of the second mounting plate 23 can also be set to be the same as the structure of the first mounting plate 13. However, it should be noted that its size can be determined according to the size of the specific tower position.

[0048] In this embodiment, the technical effect of the overall structure of the fixing bracket 2 is roughly the same as the technical effect of the above-mentioned limiting bracket 1, which will not be repeated here. Secondly, the second mounting plate 23 not only has a second through hole 21 for the cable 01 to pass through, so as to limit and fix the cable 01, but also provides an installation position for the fixing component 3, so that the third through hole 31 provided on the fixing component 3 can correspond to the second through hole 21 and the first through hole 11, thereby further ensuring the overall verticality of the cable 01 in the tower. It has a simple structure, a reasonable design, and is easy to implement and install.

[0049] Alternatively, as Figure 5 、 Figure 6 and Figure 8 As shown, the fixing assembly 3 includes a third frame 32 and a fixing clamp 33 . The third frame 32 is disposed on the fixing bracket 2 . The fixing clamp 33 is connected to the third frame 32 and is used to clamp and fix the cable 01 .

[0050] Specifically, the third frame 32 is a square frame structure as a whole and has four mounting feet. A fixed clamp 33 is arranged above the four mounting feet. The mounting feet are connected to the second mounting plate 23 of the fixed bracket 2. The fixed clamp 33 is composed of two oppositely arranged clamping parts. The two clamping parts are symmetrically provided with grooves. After the two clamping parts are connected into one, the two grooves constitute a third through hole 31. The two clamping parts can be connected to the third frame 32 by bolts, and the fixed clamp 33 is made of nylon material to prevent wear on the cable 01.

[0051] In this embodiment, by setting up the third frame 32, an installation position can be provided for the fixing clamp 33, and a certain space can be left between the fixing bracket 2 or the intermediate platform 9, which is convenient for the installation and fixation of the cable 01. The fixing clamp 33 is set to fix the cable 01, and is connected to the cable 01 by clamping and fixing, which prevents damage to the cable 01. The tightness of the fixing clamp 33 can be adjusted to adapt to cables 01 of different diameters. The structural design is reasonable and easy to install.

[0052] Alternatively, as Figures 5 to 7 As shown, the fixing assembly 3 also includes a third mounting plate 34, and waist-shaped holes 321 are respectively provided at the opposite ends of the third frame 32. The two ends of the third mounting plate 34 are connected to the third frame 32 through the waist-shaped holes 321, and the two ends of the fixing clamp 33 are respectively connected to the third mounting plate 34 and the third frame 32.

[0053] Specifically, the third mounting plate 34 is a long strip structure, and is provided with bends at both ends to constitute connecting parts at both ends. Connecting holes are provided on the two connecting parts, and are connected with the waist-shaped holes 321 through connecting parts such as bolts. At the same time, corresponding mounting holes are provided on the third mounting plate 34, the fixed clamp block 33 and the third frame 32, and the mounting hole on the fixed clamp block 33 is a through hole. The three can be connected by connecting parts such as bolts and the mounting holes. The structure is reasonable, easy to implement, and convenient to install and disassemble.

[0054] In this embodiment, a waist-shaped hole 321 is provided on the third frame 32, and the waist-shaped hole 321 is used to connect the third mounting plate 34, and then the two ends of the fixing clamp 33 are respectively connected to the third mounting plate 34 and the third frame 32, that is, the fixing clamp 33 is located between the third mounting plate 34 and the third frame 32 for installing the fixing clamp 33. Then, the fixing clamp 33 can be moved in the waist-shaped hole 321 through a connecting part such as a bolt to adjust the tightness of the fixing clamp 33, so that the fixing assembly 3 can adapt to cables 01 of different diameters, and the tightness of the fixing clamp 33 clamping the cable 01 can be adjusted at any time. The structure is reasonable, easy to adjust, and has a wide range of adaptability.

[0055] Alternatively, as Figure 1 、 Figure 2 and Figure 9 As shown, the cable fixing device further includes a cable sheath 4 , which is used to be sleeved on the cable 01 and to be arranged at the first through hole 11 .

[0056] Specifically, the cable sheath 4 is made of nylon material and is cylindrical in shape as a whole. It can be set as two semi-cylindrical structures, connected by connecting ears on both sides, and clamped on the cable 01. At the same time, the cable sheath 4 can also be set at the hole on the tower top platform 8 for the cable 01 to pass through. The length of the cable sheath 4 is greater than the length of the first through hole 11 in the axial direction, and greater than the length of the hole set on the tower top platform 8 in the axial direction, thereby protecting the cable 01 located at the first through hole 11 and the hole on the tower top platform 8 to the greatest extent.

[0057] In this embodiment, a cable sheath 4 is provided, which is sleeved on the cable 01 and provided at the first through hole 11 and the hole opened on the tower top platform 8, to prevent the cable 01 in the twisted cable section here from causing friction and wear with the hole on the tower top platform 8 and the first through hole 11 of the limiting bracket 1 due to its twisting and swinging during use, thereby effectively protecting the cable 01 located here, thereby improving the service life of the cable 01, and the structure is simple and easy to install.

[0058] Alternatively, as Figure 1 、 Figure 3 、 Figure 4 and Figure 10 As shown, the cable fixing device further includes a cable retainer 5 , which is disposed in the first through hole 11 and the second through hole 21 .

[0059] Specifically, the cable guard 5 is made of nylon material, which effectively reduces the wear of the cable 01 located in the first through hole 11 and the second through hole 21, and the cable guard 5 is in a circular shape as a whole, which can be snap-connected to the circumference of the first through hole 11 and the second through hole 21, and can also be connected to the first through hole 11 and the second through hole 21 through a connecting piece. In addition, the cable guard 5 can also be set in the hole on the tower top platform 8 for the cable 01 to pass through and the hole on the intermediate platform 9 for the cable 01 to pass through.

[0060] In this embodiment, by respectively arranging cable guards 5 in the first through hole 11 and the second through hole 21, as well as in the hole on the tower top platform 8 for the cable 01 to pass through and in the hole on the intermediate platform 9 for the cable 01 to pass through, the cable 01 can be effectively limited while further prevented from being worn, and the cable 01 can be further protected, thereby further improving the service life of the cable 01.

[0061] Alternatively, as Figure 1 、 Figure 5 and Figure 15 As shown, the fixing assembly 3 is also used to be arranged on the tower bottom platform 10, and the third through hole 31 is used to be arranged corresponding to the hole on the tower bottom platform 10 for the cable 01 to pass through.

[0062] Specifically, the tower bottom platform 10 is used to install an electrical cabinet, and during the installation of the cable 01 of the wind turbine, the cable 01 needs to be led to the electrical cabinet located below the tower bottom platform 10 for connection, and then a hole for the cable 01 to pass through can be opened on the tower bottom platform 10, and a cable guard 5 is also provided in the hole, and the hole is located in the middle of the tower bottom platform 10. Accordingly, the fixing component 3 is provided in the middle of the tower bottom platform 10 so that the third through hole 31 is provided corresponding to the hole.

[0063] In this embodiment, by also providing a fixing component 3 on the tower bottom platform 10, a hole for the cable 01 to pass through can be opened on the tower bottom platform 10 at a position corresponding to the third through hole 31, and then connected to the electrical cabinet located below the tower bottom platform 10, so that the cable 01 from top to bottom in the tower tube is always kept in a vertical state without any turning points, and thus there are no bad stress points, thereby ensuring the structural strength and stability of the cable 01 during installation and use, making it easier to install and further improving the service life of the cable 01.

[0064] Alternatively, as Figure 1 、 Figures 11 to 14 As shown, the cable fixing device also includes a saddle bridge 6 and a cable wall clamp 7. The saddle bridge 6 is used to transfer the cable 01, and the cable wall clamp 7 is used to fix the cable 01.

[0065] It should be noted that when installing the cable 01 of the wind turbine, the cable 01 is generally pulled up from top to bottom by a lifting device and is gradually installed and fixed. When it is located at the bottom of the tower, the overhanging amount of the cable 01 here is already very small, and the cable 01 here basically does not swing. Therefore, the cable 01 located here can also be led to the inner wall of the tower through the saddle bridge 6 and fixed through the cable wall clamp 7, and then connected to the electrical cabinet along the inner wall of the tower.

[0066] In this embodiment, by setting up a saddle bridge 6, it can be connected to the inner wall of the bottom of the tower, and the cable 01 located at the bottom of the tower can be transferred to the inner wall of the tower, and this section of cable 01 can be fixed on the inner wall of the tower by setting a cable wall clamp 7, so that this section of cable 01 can be connected to the electrical cabinet along the inner wall of the tower, and the connection and installation are relatively convenient, easy to implement, and easy to operate.

[0067] Specifically, the saddle bridge 6 includes a fourth mounting plate 61 and a cantilever 62 that are interconnected. The cantilever 62 is provided with two clamping holes facing different cable clamps 63. The two clamping holes face different cable clamps 63 to clamp the connecting cable 01 respectively, and change the extension direction of the cable 01. The cantilever 62 is used to overlap and turn the receiving cable 01. The fourth mounting plate 61 is used to connect to the inner wall of the tower.
