[0002] In wind turbines, especially megawatt-class wind turbines, many cables are installed, connecting the nacelle and tower to the external power grid. When the wind turbine performs yaw operations, it will generate large vibrations and shakes, and may even cause the cables to hit the inner wall of the tower or other components, so it is necessary to restrain the installed cables.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0032] In the description of this application, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In the description of the present application, if there is a description with reference to the terms "one embodiment", "some embodiments", "an embodiment", "some examples", "some embodiments", "illustrative embodiment", "example", "specific example", "some examples", etc., it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0034] The embodiment of the present application provides a cable protection assembly, which includes a spacer ring 100 and a sheath 200. Both the spacer ring 100 and the sheath 200 can separate a plurality of cables and provide a certain positioning effect on the cables. Under the separation effect of the spacer ring 100 and the sheath 200, a certain interval exists between the cables, which can avoid collision between the cables, thereby protecting the cables.

[0035] Furthermore, the spacer ring 100 needs to surround the outside of each cable, and the spacer ring 100 needs to form a connection seam through a detachable connection, so that the cable can enter the interior of the spacer ring 100 along the connection seam. In the present application, the connection seam of the spacer ring 100 is not limited to a single position of the spacer ring 100, so as to avoid the situation where the structural strength of the spacer ring 100 is significantly reduced at the connection seam position, and it is also convenient to ensure that the spacer ring 100 is subjected to balanced force at various locations.

[0036] like Figure 2 and Figure 3 As shown, in some examples, the spacer ring 100 includes a first substrate and a second substrate, both of which are formed into annular structures, and the first substrate and the second substrate have substantially the same shape, so that the first substrate and the second substrate can form a consistent separation and positioning effect on each cable.

[0037] The first substrate and the second substrate are connected in parallel to form a whole, namely, the spacer ring 100 .

[0038] Furthermore, the first base includes a plurality of first separation units 101, each of which is connected end to end in sequence to form a ring, and each of the first separation units 101 is used to separate the cables inside the ring 100-shaped structure. It is worth noting that there is no connection relationship between adjacent first separation units 101, only a mutually conflicting connection relationship is formed, and each of the first separation units 101 maintains a ring shape by connecting to the second base.

[0039] Similarly, the second base includes a plurality of second separation units 102, each of which is connected end to end in sequence to form a ring, and each second separation unit 102 is also used to separate the cables inside the ring 100-shaped structure. It is worth noting that there is no connection relationship between adjacent second separation units 102, only a connection relationship that interferes with each other is formed, and each second separation unit 102 maintains a ring shape by connecting to the first base.

[0040] Specifically, the connection position of the adjacent first partition units 101 and the connection position of the adjacent second partition units 102 are both the connection seam positions of the spacer ring 100, and the cables enter the interior of the spacer ring 100 through the connection seam positions, so that the spacer ring 100 surrounds the outside of each cable.

[0041] At the same time, the connection position of the adjacent first separation units 101 and the connection position of the adjacent second separation units 102 deviate from each other, so that the connection seam in the first substrate and the connection seam in the second substrate are misaligned, so that the connection seam is not limited to a single position of the spacer ring 100, avoiding a significant drop in strength of the spacer ring 100 at the connection seam position, thereby ensuring the overall connection strength of the spacer ring 100.

[0042] In addition, if the connecting seam of the first substrate matches the connecting seam of the second substrate, that is, no misalignment is formed, then a single first partition unit 101 and a single second partition unit 102 can form a whole, but the whole cannot be connected with other first partition units 101 and second partition units 102, and the entire partition ring 100 is still in a dispersed state and cannot form a stable annular structure. In the present application, the connecting seam of the first substrate and the second substrate is staggered, so that each first partition unit 101 can contact and form a connection relationship with two second partition units 102, and each second partition unit 102 can also contact and form a connection relationship with two first partition units 101, thereby ensuring that the various components of the partition ring 100 can maintain a stable relative position, that is, ensuring the stability of the annular structure.

[0043] In some examples, the first substrate and the second substrate are both formed into a circular ring structure, and the first partition unit 101 and the second partition unit 102 are both formed into an arc structure.

[0044] Wherein, two first partition units 101 are provided, and two second partition units 102 are also provided, so that the first partition units 101 are formed into a semicircular arc structure, and the second partition units 102 are also formed into a semicircular arc structure. Each first partition unit 101 is in contact with and connected to two second partition units 102, and each second partition unit 102 is in contact with and connected to two first partition units 101.

[0045] Specifically, a plurality of connection holes are provided on the surface of each first partition unit 101, and a plurality of connection holes are provided on the surface of each second partition unit 102. The connection holes are used to install fasteners such as bolts, so as to realize parallel and detachable connection between the first substrate and the second substrate.

[0046] It is understandable that the parallel connection of the first substrate and the second substrate can increase the thickness of the spacer ring 100, ensure that there is a sufficient contact area between the spacer ring 100 and the cable, and improve the position stability of the cable. If the first substrate and the second substrate are not spliced ​​together, and the spacer ring 100 with a larger thickness is directly manufactured, a connection seam must be set at a specific position on the spacer ring 100, which reduces the structural strength of the spacer ring 100 and makes it difficult to maintain the stable shape of the spacer ring 100.

[0047] In some examples, a plurality of first partition structures 103 are disposed on the inner wall of the first substrate. The first partition structures 103 are used to install cables. To ensure that the cables are evenly laid, the first partition structures 103 are evenly distributed around the circumference.

[0048] Similarly, the inner wall of the second base body is provided with a plurality of second partition structures 104 , which are also used to install cables. To ensure that the cables are evenly laid out, the second partition structures 104 are also evenly distributed around the circumference.

[0049] Therein, each first partition structure 103 corresponds to each second partition structure 104 one by one, that is, a single first partition structure 103 together with its corresponding second partition structure 104 jointly define the position of a cable.

[0050] In some examples, the first partition structure 103 and the second partition structure 104 are both formed as groove structures, and the shape of the groove structure matches the cross-sectional shape of the cable to facilitate the embedding of the cable.

[0051] It can be understood that when the first partition structure 103 and the second partition structure 104 are both groove structures, the corresponding relationship between the first partition structure 103 and the second partition structure 104 is that the two groove structures are connected to each other.

[0052] In some examples, it is difficult to completely define the position of the cable only by the first partition structure 103 and the second partition structure 104, and the cable needs to be further tightened. Therefore, the spacer ring 100 is provided with a plurality of perforations 105, and the perforations 105 are used to set cable ties, which can surround the cable and apply a certain tightening force to the cable to prevent the cable from moving in the first partition structure 103 and the second partition structure 104 and causing cable wear. When the twisting force of individual cables is too large, the cable ties where they are located will break after receiving excessive torque, thereby releasing the fixing effect of the cable. Therefore, it is necessary to pay attention to replacing cable ties during daily inspections.

[0053] Among them, the number of perforations 105, the number of first partition structures 103 and the number of second partition structures 104 are all equal, and the perforations 105 pass through the outer wall and the inner wall of the spacer ring 100. The cable tie passes through a single perforation 105 from the outside of the spacer ring 100 to the inside of the spacer ring 100. After entering the interior of the spacer ring 100, the cable tie bypasses the cable and then passes through the spacer ring 100 from other perforations 105.

[0054] Furthermore, the first partition unit 101 is provided with a plurality of first grooves, and the opening of each first groove faces the second partition unit 102. Meanwhile, the second partition unit 102 is provided with a plurality of second grooves, and the opening direction of each second groove faces the first partition unit 101. The position of each first groove corresponds to the position of each second groove, and the corresponding first grooves and second grooves are connected to form a through hole 105.

[0055] In some examples, the sheath 200 is spaced apart from the spacer ring 100 . Similar to the spacer ring 100 , the sheath 200 is also used to separate and position the cables.

[0056] like Figure 4 , Figure 5 and Figure 6 As shown, the sheath 200 includes an inner sheath 201 and an outer sheath. Both the inner sheath 201 and the outer sheath are roughly formed into a cylindrical structure. The inner sheath 201 is located inside the outer sheath. The sheath 200 is formed into a double-layer cylindrical structure.

[0057] A space for laying cables is defined between the inner sleeve 201 and the outer sleeve, and both the inner sleeve 201 and the outer sleeve can separate and position the cables. Specifically, the sheath 200 is made of plastic with a corresponding flame retardant grade.

[0058] In some examples, since the cable is in the space between the inner sleeve 201 and the outer sleeve, the outer wall of the inner sleeve 201 faces the cable, and the inner wall of the outer sleeve faces the cable.

[0059] Furthermore, the inner sleeve 201 and the outer sleeve are both formed into a cylindrical structure, and the outer wall of the inner sleeve 201 is provided with a plurality of first positioning structures 203, which are used to position the cable. To ensure that the cable is evenly distributed between the inner sleeve 201 and the outer sleeve, the first positioning structures 203 are evenly distributed in a circle on the inner sleeve 201.

[0060] Similarly, the inner wall of the outer jacket is provided with a plurality of second positioning structures 204 , which are also used to position the cable, and the second positioning structures 204 are also evenly distributed in a circumference on the outer jacket.

[0061] It can be understood that the number of cables, the number of first positioning structures 203 and the number of second positioning structures 204 are all equal, and each first positioning structure 203 corresponds to each second positioning structure 204 one by one.

[0062] Specifically, the first positioning structure 203 and the second positioning structure 204 both adopt a groove structure extending along the length direction of the sheath 200, and the shape of the groove structure corresponds to the shape of the cable, so that the cable can be easily embedded in the first positioning structure 203 and the second positioning structure 204. The inner sleeve 201 and the outer sleeve clamp the cable on both sides of the cable through the first positioning structure 203 and the second positioning structure 204, thereby completing the positioning of the cable.

[0063] In some examples, the outer jacket includes a plurality of positioning units 202, and each positioning unit 202 is connected end to end in sequence. Specifically, two positioning units 202 are provided, and when the outer jacket is formed into a cylindrical structure, the two positioning units 202 are both formed into a semi-cylindrical structure.

[0064] The two positioning units 202 are detachably connected, and when the two positioning units 202 are detached from each other, the cable can be installed in the inner sleeve 201. After the cable is embedded in the first positioning structure 203, the two positioning units 202 are connected as one.

[0065] In some examples, to facilitate the detachable connection between two positioning units 202 , an ear plate 205 is provided on the edge of the positioning unit 202 , and adjacent positioning units 202 are detachably connected via the ear plate 205 .

[0066] Specifically, the ear plate 205 is provided with a connection hole for the fastener to pass through, and the adjacent positioning units 202 are detachably connected through the ear plate 205 and the fastener.

[0067] An embodiment of the present application provides a cable laying device, which includes a saddle bridge and the above-mentioned cable protection assembly.

[0068] Among them, the saddle bridge is used to carry cables, the sheath 200 is connected to the saddle bridge, and the cable part at the bottom of the sheath 200 is installed with several spacer rings 100. The spacer rings 100 are used to separate and position each cable, and have a certain structural strength, which can effectively reduce the collision and wear between cables in the daily operation of the wind turbine. Similarly, the sheath 200 can separate and position each cable, further reducing the collision and wear between cables. When wear occurs, the sheath 200 and the spacer ring 100 are worn first, thereby extending the service life of the cable. At the same time, the detachable sheath 200 and the spacer ring 100 are also easy to replace.

[0069] Specifically, three spacer rings 100 are provided. Since there is a certain degree of kinking at the cable saddle of the wind turbine generator set, the spacer ring 100 at the lowest position of the cable will always remain at the lowest position due to gravity, and the other two spacer rings 100 mainly rely on fixed friction and cable kinking deformation to maintain relative positions.

[0070] The above is a detailed description of the implementation methods of the present application in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
