Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a cable protection device. Background Art

[0002] Cables are the primary means of transmitting electricity during wind power generation. This process requires the transport of multiple, long cables. To prevent friction between cables, which can affect their lifespan, cable fixtures are often used to separate the cables.

[0003] Currently, cable fixtures primarily consist of a mounting frame and multiple fixing sleeves. The sleeves are spaced apart and securely connected to the mounting frame. Each sleeve, using a clamp or other form factor, is removably secured to each cable. The combination of the sleeves and mounting frame allows for the separation of cables, reducing or preventing friction between them.

[0004] As time goes by, the amount of stretching of each cable is different, and each fixing sleeve and fixing frame are fixedly connected, resulting in the elongation of each cable cannot be compensated, which leads to excessive fatigue of each cable over time. Utility Model Content

[0005] The present application provides a cable protection device to solve the problem that existing cable fixing devices cannot compensate for the elongation of the fixed cable.

At the same time, the present application changes the setting method of the connecting component and the fixing frame, and uses the mounting parts to enable the connecting component to be movably set relative to the fixing frame. When the extension amount of each cable varies after long-term use, since each connecting component is movably connected to the fixing frame, it means that the cable fixed on the connecting component can move in a small range relative to the fixing frame to compensate for the different extension amounts of each cable, avoid excessive fatigue of each cable, and increase the service life of the cable.

[0011] In a possible implementation, one end of the second connecting portion is connected to the fixing frame, and the other end of the second connecting portion is connected to a stopper, and the distance between the stopper and the fixing frame is adjustable;

[0012] The stopper is used to prevent the first connecting portion and the second connecting portion from being separated.

[0013] In a possible implementation, the mounting member further includes an elastic member, and the elastic member is located between any two of the first connecting portion, the second connecting portion, and the fixing bracket.

[0014] In one possible implementation, the connection assembly includes a fixing member and at least one connecting member, the fixing member is connected to the first connecting portion, the connecting member is detachably connected to the fixing member, and the connecting member is used to be detachably connected to a partial structure of the cable.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0036] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0037] As the capacity of offshore wind turbines increases, the number and cross-sectional area of ​​the power cables transmitting electrical energy are also increasing, placing higher demands on twist cable protection for each cable. During the twisting process, each cable segment will experience axial contraction, and friction will occur between the cables, reducing the service life of each cable. To this end, it is necessary to install corresponding fixing devices on each cable to achieve overall compensation for the vertical lift of each cable in the twisted segment, and to segment the individual cables to avoid friction between the cables.

[0038] The terminology of twist cable segments is explained as follows:

[0039] During wind turbine operation, the turbine's nose must always face the wind. As wind direction changes, the turbine's nose must rotate at any time. To prevent the cable from twisting during rotation, a saddle bridge is typically installed on the inner wall of the tower. As the cable is laid downward from the wind turbine, it passes through the saddle bridge. A certain length of cable is reserved between the wind turbine and the saddle bridge to compensate for twisting of the wind turbine. This section of cable reserved in advance to compensate for turbine twisting is called a twist cable section.

[0040] Currently, cable fixtures consist of a mounting frame and multiple fixing sleeves. The mounting frame utilizes a circular ring structure, while the fixing sleeves utilize a clamping hoop structure. The fixing sleeves are fixed to the mounting frame at intervals along its circumferential direction. During use, each fixing sleeve is securely connected to the corresponding cable, and the mounting frame is then fixed in place. This fixed mounting frame compensates for the vertical lift of each cable in the twisted cable section. Spacing the cables on the mounting frame prevents friction between them.

[0041] However, the manufacturing process for each cable, as well as the assembly process for each cable and cable protector, all have certain variations. Consequently, there are differences in the lift between each cable group during twisting. These variations become increasingly pronounced as the wind turbine ages. The elongation of each cable varies. Because the mounting bracket is in a specific position, and each cable is fixed relative to the bracket by its corresponding mounting sleeve, this means that each cable has a different elongation. However, the vertical cable length is fixed in a single plane, meaning that the differences in elongation between the individual cables cannot be compensated for. Over time, this leads to excessive fatigue in each cable.

[0042] To solve the above problems, the present application changes the connection method between the fixing sleeve and the fixing frame so that the cable fixed on the fixing sleeve can be slightly offset relative to the fixing frame, so as to compensate for cables with different elongations, reduce the fatigue of each cable, and increase the service life of each cable.

[0043] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Reference Figure 1-Figure 7 As shown, a cable protection device includes a fixing frame 400 and multiple connecting components 200, each connecting component 200 is used to fix a corresponding cable 100; each connecting component 200 is arranged at intervals on the fixing frame 400, and the connecting component 200 is connected to the fixing frame 400 through a mounting member 300; the mounting member 300 includes a first connecting portion 310 and a second connecting portion 320, the first connecting portion 310 and the second connecting portion 320 are movably matched, the first connecting portion 310 is connected to the connecting component 200, and the second connecting portion 320 is connected to the fixing frame 400.

[0045] It is understood that the connection assembly 200 is equivalent to a fixing sleeve in the prior art and is primarily used to secure the corresponding cable 100. The fixing bracket 400 is equivalent to a fixing bracket 400 in the prior art and is fixed in a specific position to comprehensively compensate for the vertical lift of each cable 100 in the twisted cable section.

[0046] It can be understood that the present application utilizes the mounting member 300 to enable the connecting component 200 to be movably arranged relative to the fixing frame 400, which means that the cable 100 fixed on the connecting component 200 can change its position within a small range relative to the fixing frame 400. Then, for each cable 100 with different elongation, it can be offset to different positions relative to the fixing frame 400 under the action of the mounting member 300, so as to compensate for the elongation of each cable 100 with different elongation.

[0047] In order to enable the installation of the mounting member 300 to achieve the above effects.

[0048] For example, the first connecting portion 310 and the second connecting portion 320 of the mounting member 300 both adopt a connecting shaft structure, and the first connecting portion 310 and the second connecting portion 320 are movably connected via a joint bearing. After the first connecting portion 310 and the connecting assembly 200 are fixed and the second connecting portion 320 and the fixing frame 400 are fixed, the connecting assembly 200 can be movably arranged relative to the fixing frame 400, and the swing space of the connecting assembly 200 along the fixing frame 400 is achieved based on the length of the first connecting portion 310 and the second connecting portion. During use, the connecting assembly 200 and the cable 100 are fixed. Since the connecting assembly 200 is movably arranged relative to the fixing frame 400, under the resistance of the cables 100 with different elongations, each connecting assembly 200 can have a different offset position relative to the fixing frame 400, so as to achieve the purpose of compensating the elongation of each cable 100 with different elongations.

[0049] Exemplarily, the first connecting portion 310 of the mounting member 300 is a spring, and the second connecting portion 320 is a limiting sleeve that is sleeved over the spring. A gap is formed between the first connecting portion 310 and the second connecting portion 320. One end of the first connecting portion 310 is fixed to the connecting assembly 200, and the other end of the first connecting portion 310 is fixed to the fixing frame 400. A gap exists between one end of the limiting sleeve and the connecting assembly 200, and the other end of the limiting sleeve is fixed to the fixing frame 400. When the connecting assembly 200 is subjected to different external forces, the first connecting portion 310 will be forced to change position in different directions. The cooperation of the second connecting portion 320 can limit the range of motion of the first connecting portion 310, thereby allowing the connecting assembly 200 to have different degrees of positional displacement relative to the fixing frame 400 under the action of different external forces. During use, the connecting component 200 and the cable 100 are fixed. Since the connecting component 200 is movably arranged relative to the fixing frame 400, under the action of the resistance of the cables 100 with different elongations, each connecting component 200 can have a different offset position relative to the fixing frame 400, so as to achieve the purpose of compensating for the elongation of each cable 100 with different elongations.

[0050] In one possible implementation, the first connection portion 310 is a connection hole opened on the connection component 200, and the second connection portion 320 is a limiting column. The limiting column is inserted into the connection hole, and there is a distance between the inner wall of the connection hole and the outer wall of the limiting column.

[0051] To facilitate the arrangement and installation of the mounting member 300 , the present application provides a specific structure of the mounting member 300 .

[0052] like Figure 3As shown, the first connecting portion 310 is a through-hole structure provided on the connecting assembly 200, which serves as a connecting hole. The second connecting portion 320 is a limiting post. The limiting post can be fixedly connected to the fixing frame 400 or can be flexibly connected to the fixing frame 400. The limiting post is inserted into the connecting hole, and a gap is formed between the outer wall of the limiting post and the inner wall of the connecting hole.

[0053] This means that when the connecting assembly 200 is subjected to different external forces, it will drive the first connecting portion 310 to move along the second connecting portion 320 within a small range, reducing the distance between some positions of the first connecting portion 310 and the second connecting portion 320 while increasing the distance between other positions. This allows the connecting assembly 200 to be adjusted within a small range relative to the fixing frame 400. Therefore, when different connecting assemblies 200 are subjected to different external forces, they can have different offset positions relative to the fixing frame 400, thereby adapting to the elongation of each cable 100 fixed to each connecting assembly 200 and compensating for the elongation of each cable 100.

[0054] In one possible implementation, one end of the second connecting portion 320 is connected to the fixing frame 400, and the other end of the second connecting portion 320 is connected to a stopper 321, and the distance between the stopper 321 and the fixing frame 400 is adjustable; the stopper 321 is used to prevent the first connecting portion 310 and the second connecting portion 320 from separating.

[0055] It can be understood that the relative positions of the first connecting portion 310 and the second connecting portion 320 are: the first connecting portion 310 moves relative to the cross-sectional direction of the second connecting portion 320 (horizontally offset position), and / or the first connecting portion 310 moves along the length direction of the second connecting portion 320 (vertically offset position); so that each connecting component 200 and the fixing bracket 400 has a different offset position.

[0056] The horizontal offset position of the first connection portion 310 and the second connection portion 320 is achieved based on the hole diameter of the first connection portion 310 and the cross-sectional shape and size of the second connection portion 320. The vertical offset position of the first connection portion 310 and the second connection portion 320 is achieved based on the hole length of the first connection portion 310 and the length of the second connection portion 320.

[0057] When the aperture size of the first connecting part 310 is fixed and the cross-sectional shape and cross-sectional size of the second connecting part 320 are fixed, in order to enable the relative position of the first connecting part 310 relative to the second connecting part 320 to be adjusted, the connection method between the second connecting part 320 and the fixing frame 400 can be improved to change the moving distance of the first connecting part 310 along the length direction of the second connecting part 320, thereby achieving different positional relationships between the first connecting part 310 and the second connecting part 320.

[0058] Specifically, at least a portion of the second connecting portion 320 (limiting post) is provided with a threaded section that can be threadedly connected to the fixing frame 400. The depth of the threaded section along the fixing frame 400 controls the distance of the other end of the second connecting portion 320 (limiting post) from the fixing frame 400. Consequently, the movable distance of the first connecting portion 310 (connection hole), which is positioned outside the second connecting portion 320, along the length of the second connecting portion 320, is adjustable. To prevent the first connecting portion 310 from disengaging from the second connecting portion 320 during movement along the length of the second connecting portion 320, a stopper 321 is provided on the second connecting portion 320. The stopper 321, in conjunction with the fixing frame 400, limits the movable distance of the first connecting portion 310 along the length of the second connecting portion 320. To this end, the movable distance of the first connecting portion 310 along the length of the second connecting portion 320 can be adjusted by adjusting the position of the stopper 321 on the second connecting portion 320.

[0059] Correspondingly, on the basis of the above-mentioned threaded connection between the second connecting part 320 and the fixing frame 400, the stopper 321 adopts a nut, the outer diameter of the stopper 321 is larger than the inner diameter of the connecting hole, and other threaded segments can also be provided on the second connecting part 320. The stopper 321 and the threaded segment are threadedly connected. Changing the position of the stopper 321 on the second connecting part 320 and / or changing the position of the second connecting part 320 and the fixing frame 400 can achieve the adjustment of the distance between the stopper 321 and the fixing frame 400.

[0060] Of course, the second connecting part 320 can be fixedly connected to the fixing frame 400 at one end, and a threaded section is provided at the other end, which is threadedly connected to the stopper 321. By rotating the stopper 321 and changing the position of the stopper 321 on the second connecting part 320, the distance between the stopper 321 and the fixing frame 400 can also be adjusted.

[0061] In a possible implementation, the mounting member 300 further includes an elastic member 330 , and the elastic member 330 is located between any two of the first connecting portion 310 , the second connecting portion 320 , and the fixing bracket 400 .

[0062] It is understandable that if the twist cable protection device is rigidly connected to the cable 100, it will be difficult to ensure that each fixing point (which can be equivalent to the connection point between the connecting assembly 200 and the fixing bracket 400) can be completely maintained in the same plane during the installation process, which will cause installation errors, resulting in uneven force on each fixing point of the cable 100, which can easily cause uneven fatigue of the cable 100. To this end, the mounting member 300 of the present application also includes an elastic member 330. In the present application, the elastic member 330 is a spring that is sleeved outside the second connecting portion 320, and the two ends of the spring can be located between any two of the first connecting portion 310, the second connecting portion 320, and the fixing bracket 400.

[0063] Specifically, such as Figure 2 、 Figure 3 As shown, the elastic member 330 is a spring that is sleeved outside the second connecting portion 320. One end of the elastic member 330 is fixed to the second connecting portion 320, and the other end of the elastic member 330 is fixed to the first connecting member 210. The elastic member 330 can be a compression spring or a tension spring. When the connecting assembly 200 is not subjected to external force, the first connecting portion 310 can be abutted against the stopper 321 or the fixing frame 400 under the action of the elastic member 330, thereby limiting the position of the first connecting portion 310 relative to the fixing frame 400. The provision of the elastic member 330 can, to a certain extent, alleviate the problem of the fixing points of each cable 100 and the fixing frame 400 not being aligned, thereby avoiding or reducing the fatigue effects of the cables 100.

[0064] In one possible implementation, the connecting assembly 200 includes a fixing member 220 and at least one connecting member 210 , the fixing member 220 is connected to the first connecting portion 310 , the connecting member 210 is detachably connected to the fixing member 220 , and the connecting member 210 is used for detachable connection to the cable 100 .

[0065] It can be understood that the fixing member 220 is movably connected to the fixing frame 400, the connecting member 210 is connected to the fixing member 220, and the connecting member 210 is fixed to the cable 100, so that the cable 100 can be movably set relative to the fixing frame 400. When the elongation of each cable 100 is different, the connection position of each cable 100 and the connecting member 210 will have a different offset position relative to the fixing frame 400 to complement the elongation of each cable 100.

[0066] However, in the prior art, the power cables 100 used in wind turbines typically consist of three phases (UV, W) fixed together in a ring. This can be simply understood as a single power cable 100 consisting of three corresponding wires 110, referred to as a three-phase cable 100. In the prior art, the three-phase cables 100 are directly secured together with a fixing sleeve. However, due to the inevitable differences in axial lift of the UV, W, and three-phase cables 100, and the synchronous fixing method used for the three-phase cables 100, these differences in axial lift cannot be offset. This results in prolonged and frequent tension between the three wires 110 (cable 100), reducing the service life of the cable 100 and causing wear and tear, or even damage.

[0067] To address the above-mentioned issues, the connection assembly 200 of the present application includes a fixing member 220 and at least one connecting member 210. When the cable 100 is a single wire 110, the cable 100 can be fixed to a single connecting member 210. When the cable 100 is composed of more than one wire 110, multiple connecting members 210 can be provided on the fixing member 220 to fix to corresponding wires 110. Therefore, the present application states that the connecting member 210 is fixed to a partial structure of the cable 100.

[0068] Specifically, in this application, Figure 4 As shown, the connection assembly 200 includes a fixing member 220 and three connecting members 210. The fixing member 220 has a plate-like structure and is positioned in contact with the fixing frame 400. The first connecting portion 310 is provided on the fixing member 220. The three connecting members 210 are evenly distributed in a ring around the first connecting portion 310. The connecting members 210 can adopt a clamp structure known in the prior art to secure the wires 110 of the three-phase cable 100. Due to the appropriate number of connecting members 210 on the connection assembly 200, it can accommodate cables 100 composed of different numbers of wires 110. Each wire 110 of the cable 100 can be secured separately, reducing friction between the wires 110.

[0069] In one possible implementation, the fixing member 220 is provided with the same number of clamping members 230 as the connecting member 210, and the clamping members 230 include two clamping arms 231 and a locking member 233. Each clamping arm 231 is rotatably connected to the fixing member 220, and the locking member 233 is used to lock or unlock the two clamping arms 231; the fixing member 220 and the two clamping arms 231 constitute a clamping space for connecting the connecting member 210.

[0070] In order to achieve a detachable connection between the connecting member 210 and the fixing member 220, in this application, the same number of clamping members 230 as the connecting members 210 are provided. The clamping members 230 can adopt the clamp structure in the prior art, or can adopt the bolt connection structure in the prior art, so as to achieve a detachable connection between the connecting member 210 and the fixing member 220.

[0071] In this application, if Figure 4As shown, the clamping member 230 includes two clamping arms 231, which are in the shape of circular plates. The two clamping arms 231 are arranged to open and close relative to each other. One end of the clamping arm 231 is hinged to the fixing member 220, and the other end of the clamping arm 231 is provided with a connecting plate protruding outward. The two clamping arms 231 move relative to each other. The two connecting plates are arranged relative to each other. A locking member 233 passes through the two connecting plates to achieve the locking of the two clamping arms 231. The locking member 233 uses a bolt and nut to achieve the locking and unlocking of the two clamping arms 231. The two clamping arms 231 and the fixing member 220 can form a clamping space, which is used to fix the connecting member 210. As a result, the fixing member 220 and each connecting member 210 can be detachably connected.

[0072] In one possible implementation, at least two positioning portions 212 are provided on the connecting member 210, and at least two limiting portions 232 are provided in the clamping space. Each limiting portion 232 is used to connect each positioning portion 212 to connect the connecting member 210 with the clamping space; each positioning portion 212 is in elastic contact with the corresponding limiting portion 232.

[0073] In order to facilitate the positioning and clamping of the connecting member 210 and the clamping space, in this application, at least two positioning parts 212 are provided on the connecting member 210, and the positioning part 212 adopts a recessed groove or a raised block, and a limiting part 232 is provided on the inner wall of the clamping space. Correspondingly, the limiting part 232 adopts a raised block or a recessed groove. By utilizing the cooperation of the positioning part 212 and the corresponding limiting part 232, the connecting member 210 can be snap-fitted and positioned in the clamping space, so as to ensure a stable connection between the connecting member 210 and the clamping space.

[0074] like Figure 4 As shown, in the present application, three limiting portions 232 are provided in each clamping space. The three limiting portions 232 are respectively provided on the fixing member 220 and the two clamping arms 231. The two limiting portions 232 are evenly distributed in the clamping space, and each limiting portion 232 has a recessed groove structure. There are three positioning portions 212, which are evenly distributed on the connecting member 210. The positioning portions 212 have a raised block structure. When connecting the connecting member 210 and the clamping space, one of the positioning portions 212 is first engaged with the limiting portion 232 on the fixing member 220 for positioning. Then, the two clamping arms 231 are rotated relative to each other so that the limiting portion 232 on the clamping arm 231 engages with the corresponding positioning portion 212. Then, the two clamping arms 231 are fixed using the locking member 233 to complete the assembly of the connecting member 210 and the corresponding clamping space.

[0075] In the present application, an elastic block 2321 is fixed in the limiting portion 232, and the elastic block 2321 can be in contact with any side wall of the positioning portion 212 (eg, Figure 3Alternatively, the elastic block 2321 may wrap around the positioning portion 212 (e.g., Figure 6 、 Figure 7 ) so that the elastic block 2321 elastically contacts the positioning portion 212. The elastic block 2321 is made of an elastic material such as rubber or silicone. The presence of an elastic block 2321 within each of the three limiting portions 232 allows the connector 210 to vary its position (rotate and / or move up and down) within a small range in the horizontal direction (radially relative to the wires 110). This allows the wires 110 connected to the various connectors 210 on the fixing member 220 to lie in different planes, compensating for the radial position of each wire 110 and ensuring uniform force on each connecting assembly 200.

[0076] In a possible implementation, the connector 210 includes at least two fixing half rings 211 . The two fixing half rings 211 are spliced ​​and fixed to form a clamping ring, which is used to be fixed to a part of the structure of the cable 100 .

[0077] To facilitate the detachable connection between connector 210 and wire 110, the connector 210 of the present application utilizes a split structure, consisting of at least two fixed half-rings 211. The fixed half-rings 211 wrap around the periphery of wire 110, clamping onto the outside of wire 110. The first half-rings 211 are then secured sequentially with connecting bolts 214 to secure the clamping ring to wire 110. The positioning portion 212 is located on the outer periphery of the clamping ring. After securing connector 210 to wire 110, connector 210 is then secured within the corresponding clamping space.

[0078] In this application, if Figure 4 、 Figure 5 As shown, the connector 210 includes three fixed half-rings 211, which are fixed in sequence to form a snap ring. Each positioning portion 212 is formed by combining the protrusions 2121 on two adjacent fixed half-rings 211. The two fixed half-rings 211 are connected by connecting bolts 214 to connect the corresponding protrusions 2121.

[0079] In this manner, a stable connection of wires 110 of different diameters can be achieved, thereby preventing the wires 110 from being separated from the connector 210 .

[0080] In a possible implementation, at least one elastic anti-sliding block 213 is provided on the inner wall of the fixing half ring 211 , and the elastic anti-sliding block 213 is used to contact the cable 100 .

[0081] In order to avoid the rigid contact between the connector 210 and the wire 110 and damage to the wire 110, the present application provides at least one elastic anti-slip block 213 on the inner side of the fixed half ring 211, and the elastic anti-slip block 213 is made of elastic anti-slip material such as rubber and silicone.

[0082] In this application, if Figure 4 、 Figure 5 As shown, an elastic anti-sliding block 213 is provided in each fixed half ring 211 , and the elastic anti-sliding block 213 contacts the corresponding wire 110 to prevent the fixed half ring 211 from directly contacting and damaging the wire 110 .

[0083] In a possible implementation, the fixing frame 400 includes a plurality of fixing units 410 , each fixing unit 410 is detachably connected to each other, and each fixing unit 410 is correspondingly connected to each connecting assembly 200 .

[0084] To facilitate the adjustment or correction of the position of each connecting component 200, the fixing frame 400 of the present application is composed of multiple fixing units 410, and adjacent fixing units 410 are detachably connected by fastening bolts 420. The number of fixing units 410 is the same as the number of connecting components 200, and the connecting components 200 are connected to the corresponding fixing units 410.

[0085] like Figure 1 As shown, the fixing frame 400 of the present application is roughly in the form of a circular ring structure, the fixing unit 410 is in the form of an arc plate structure, and a plurality of fixing units 410 are spliced ​​in sequence to form the fixing frame 400 .

[0086] This approach is conducive to the overall replacement of each connecting component 200, and through different numbers of fixing units 410, it is also possible to form a fixing frame 400 with different structures to cope with more specific working conditions.
