Description

Technical Field

[0001] This utility model relates to the field of cable wiring protection technology, and in particular to an anti-wear protective sleeve for offshore wind power cables. Background Technology

[0002] Cables typically consist of a metal core encased in an insulation layer, the primary function of which is to prevent electrical leakage. In offshore wind power generation, the wind turbine tower can be fitted with a sheath to securely install the cable, thus providing cable routing. Furthermore, the sheath prevents wear and tear on the insulation layer caused by friction during long-term use.

[0003] Patent CN222953672U discloses a cable sheath that uses an arc-shaped clamping block and a protective sleeve to fix and protect the cable; Patent CN212543252U discloses a cable sheath that uses a left half-shell, a right half-shell, a left half-ring, and a right half-ring to fix and protect the cable.

[0004] In the aforementioned patents and some technical solutions, the protection of the cable insulation layer is achieved through an external cylindrical structure. However, in practical applications, the cable laying path often needs to be adjusted according to the actual environment. The corners where cables are laid are often the most vulnerable to friction against the cable insulation layer. Since the external structure in the current technology is a cylindrical structure, it is difficult to install it at the bends of the cable and protect that area, which has certain limitations.

[0005] Therefore, there is an urgent need for a wear-resistant protective sleeve for offshore wind power cables to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anti-wear protective sleeve for offshore wind power cables, which can effectively protect the cable bending points.

[0010] The positioning assembly includes a first connecting rod, a second connecting rod, and a positioning element. Two first connecting rods are symmetrically connected to both sides of the first sheath, and two second connecting rods are symmetrically connected to both sides of the second sheath. The first and second connecting rods on the same side of the protective sheath are hinged together. The axes of the first and second sheaths are perpendicular to the hinge axis between the first and second connecting rods. The positioning element is used to connect the first connecting rod and the second connecting rod to position the included angle between the first and second connecting rods. The positioning element is detachably connected to at least one of the first and second connecting rods.

[0011] As an improvement to the above technical solution, the first sheath and the second sheath are respectively fitted onto both ends of the third sheath.

[0012] As an improvement to the above technical solution, the third sheath further includes a plug-in section. Both ends of the corrugated pipe are fixedly connected to the plug-in section. The first sheath and the second sheath are respectively sleeved on the plug-in sections at both ends of the corrugated pipe. A limiting protrusion is provided on the outer wall of the plug-in section. The end of the first sheath that is plugged into the third sheath and the end of the second sheath that is plugged into the third sheath are both provided with a limiting groove corresponding to the limiting protrusion. The limiting protrusion is located in the corresponding limiting groove.

[0013] As an improvement to the above technical solution, both the first sheath and the second sheath include two oppositely arranged tube segments, and the two tube segments of the first sheath and the two tube segments of the second sheath can be detachably connected.

[0015] As an improvement to the above technical solution, a clamp is also included, wherein the clamp is fitted on both the first sheath and the second sheath, and a fixing rod is fixedly connected to each clamp.

[0016] As an improvement to the above technical solution, the protective sleeve further includes a first hinge rod and a second hinge rod. The first sleeve is fixedly provided with a first hinge rod that corresponds one-to-one with the first connecting rod, and the first connecting rod is hinged to the corresponding first hinge rod. The second sleeve is fixedly provided with a second hinge rod that corresponds one-to-one with the second connecting rod, and the second connecting rod is hinged to the corresponding second hinge rod.

[0017] As an improvement to the above technical solution, a positioning disk is fixedly provided at one end of the first connecting rod and the second connecting rod that are hinged together. The positioning disk is provided with a plurality of positioning connection holes, which are spaced apart around the hinge axis of the first connecting rod and the second connecting rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model discloses an anti-wear protective sleeve for offshore wind power cables. The sleeve has a corrugated pipe in the middle, allowing it to be bent. When installing cables inside the wind turbine tower, the anti-wear protective sleeve can be placed on the cable at the bends in the cable laying, and the sleeve can bend with the cable. During the bending process, the first connecting rod and the second connecting rod rotate relative to each other. When the sleeve is bent to the correct position, a positioning component connects the first and second connecting rods, fixing the angle between them and preventing further relative rotation. This fixes the degree of bending of the sleeve and positions the cable bend at that point, preventing changes in the bending degree of the cable and the protective sleeve on that point from contacting and rubbing against other components of the wind turbine tower. Therefore, this utility model of an anti-wear protective sleeve for offshore wind power cables can better protect the cable bends. Attached Figure Description

[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figure 1 - Figure 4 As shown, this embodiment provides an anti-wear protective sleeve for offshore wind power cables, including a protective sleeve 1 and a positioning assembly 2. The protective sleeve 1 includes a first sheath 11, a third sheath 13, and a second sheath 12 connected in sequence. The third sheath 13 includes a corrugated pipe 131 disposed between the first sheath 11 and the second sheath 12. The positioning assembly 2 includes a first connecting rod 21, a second connecting rod 22, and a positioning element 23. The two first connecting rods 21 are symmetrically connected to both sides of the first sheath 11, and the two second connecting rods 22 are symmetrically connected to both sides of the second sheath 12. The first connecting rod 21 and the second connecting rod 22 on the same side of the protective sleeve 1 are hinged together. The axes of the first sheath 11 and the second sheath 12 are both perpendicular to the hinge axis between the first connecting rod 21 and the second connecting rod 22. The positioning element 23 is used to connect the first connecting rod 21 and the second connecting rod 22 to position the included angle between the first connecting rod 21 and the second connecting rod 22. The positioning element 23 is detachably connected to at least one of the first connecting rod 21 and the second connecting rod 22. In this embodiment, the positioning member 23 connects the first connecting rod 21 and the second connecting rod 22 located on the same side of the protective sleeve 1.

[0043] The offshore wind power cable abrasion protection sleeve provided in this embodiment has a corrugated pipe 131 in the middle, allowing it to be bent. When installing cables inside the wind turbine tower, the abrasion protection sleeve can be placed on the cable at the bends in the cable laying, and the sleeve 1 can bend with the cable. During the bending process of the sleeve 1, the first connecting rod 21 and the second connecting rod 22 rotate relative to each other. After the sleeve 1 is bent to the correct position, the positioning element 23 connects the first connecting rod 21 and the second connecting rod 22, positioning the included angle between them, preventing further relative rotation and thus fixing the bending degree of the sleeve 1. This positions the cable bending degree at that point, preventing changes in the bending degree of the cable and the sleeve 1 on it from contacting and rubbing against other components of the wind turbine tower. Therefore, the offshore wind power cable abrasion protection sleeve in this embodiment can better protect the cable bending points.

[0044] Furthermore, such as Figure 1 - Figure 3 As shown, the first sheath 11 and the second sheath 12 are respectively fitted onto the two ends of the third sheath 13, so as to realize the connection between the first sheath 11 and the third sheath 13 and between the second sheath 12 and the third sheath 13 by fitting them together.

[0045] Furthermore, such as Figure 2 and Figure 3 As shown, the third sheath 13 also includes a plug-in section 132. Both ends of the corrugated pipe 131 are fixedly connected to the plug-in section 132. The first sheath 11 and the second sheath 12 are respectively fitted onto the plug-in sections 132 at both ends of the corrugated pipe 131. A limiting protrusion 1321 is provided on the outer wall of the plug-in section 132. A limiting groove 102 corresponding to the limiting protrusion 1321 is provided at the end where the first sheath 11 and the third sheath 13 are plugged in, and at the end where the second sheath 12 and the third sheath 13 are plugged in. When the first sheath 11 and the second sheath 12 are fitted onto the corresponding plug-in section 132, the limiting protrusion 1321 is located within the corresponding limiting groove 102, making the connection between the third sheath 13 and the first sheath 11, and between the third sheath 13 and the second sheath 12, secure and preventing them from easily coming off. In this embodiment, each plug segment 132 is provided with a plurality of limiting protrusions 1321 spaced apart along the axial direction of the plug segment 132. The limiting protrusions 1321 surround the plug segment 132. The limiting groove 102 on the first sheath 11 extends circumferentially along the inner wall of the first sheath 11. The limiting groove 102 on the second sheath 12 extends circumferentially along the inner wall of the second sheath 12.

[0046] Furthermore, such as Figure 1 - Figure 3As shown, both the first sheath 11 and the second sheath 12 include two oppositely arranged tube segments 101. The two tube segments 101 of the first sheath 11 and the two tube segments 101 of the second sheath 12 are detachably connected. Both the first sheath 11 and the second sheath 12 employ a detachable splicing method with two tube segments 101. When connecting the first sheath 11 to the third sheath 13, the two tube segments 101 of the first sheath 11 can be separated and respectively fitted onto the third sheath 13 before connecting the two tube segments 101. The connection method between the second sheath 12 and the third sheath 13 is the same as the connection method between the first sheath 11 and the third sheath 13.

[0047] Furthermore, such as Figure 1 As shown, both the first sheath 11 and the second sheath 12 further include connecting blocks 103 and connecting bolts. Multiple connecting blocks 103 are fixedly disposed on the outer wall of each tube segment 101. The connecting blocks 103 on two oppositely positioned tube segments 101 are arranged in a one-to-one correspondence, and the corresponding connecting blocks 103 are detachably connected to each other via connecting bolts. Specifically, each connecting block 103 is provided with a connecting hole 1031, through which the connecting bolt passes. In this embodiment, two connecting blocks 103 are spaced apart on both sides of each tube segment 101, meaning each tube segment 101 has four connecting blocks 103. Two oppositely positioned tube segments 101 are connected via eight connecting blocks 103 and four connecting bolts.

[0048] Optionally, such as Figure 1 - Figure 3 As shown, the abrasion-resistant protective sleeve for offshore wind power cables provided in this embodiment also includes clamps 3. Clamps 3 are fitted on both the first sheath 11 and the second sheath 12, and fixing rods 31 are fixedly connected to both clamps 3. The fixing rods 31 are used to connect to the wind turbine tower to fix the first sheath 11 and the second sheath 12 to the wind turbine tower, thereby fixing the cable at a designated position.

[0049] Optionally, such as Figure 1 , Figure 2 and Figure 4As shown, the protective sleeve 1 also includes a first hinge rod 14 and a second hinge rod 15. The first sleeve 11 is fixedly provided with a first hinge rod 14 corresponding to each of the first connecting rods 21, and each first connecting rod 21 is hinged to its corresponding first hinge rod 14. The second sleeve 12 is fixedly provided with a second hinge rod 15 corresponding to each of the second connecting rods 22, and each second connecting rod 22 is hinged to its corresponding second hinge rod 15. A first hinge rod 14 is provided on each side of the first protective sleeve 1 to facilitate the connection between the first connecting rod 21 and the first sleeve 11. Similarly, a second hinge rod 15 is provided on each side of the second protective sleeve 1 to facilitate the connection between the second connecting rod 22 and the second sleeve 12.

[0050] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, a positioning disk 211 is fixedly provided at one end of the first connecting rod 21 and the second connecting rod 22, which are hinged together. The positioning disk 211 has multiple positioning connection holes 2111, which are spaced apart around the hinge axis of the first connecting rod 21 and the second connecting rod 22. The second connecting rod 22 has a positioning threaded hole. A positioning element 23 is partially located within the positioning threaded hole and threadedly connected to the second connecting rod 22, and partially extends into the positioning connection hole 2111. The threaded connection between the positioning element 23 and the second connecting rod 22, and its extension into the positioning connection hole 2111 on the positioning disk 211, prevents relative rotation between the first connecting rod 21 and the second connecting rod 22, thereby positioning the included angle between them. When it is necessary to adjust the included angle between the first connecting rod 21 and the second connecting rod 22, rotate the positioning member 23 until the positioning member 23 leaves the positioning connection hole 2111. At this time, the positioning member 23 no longer hinders the relative rotation between the first connecting rod 21 and the second connecting rod 22. Adjust the included angle between the first connecting rod 21 and the second connecting rod 22, and then rotate the positioning member 23 so that the positioning member 23 is inserted into the corresponding positioning connection hole 2111 on the positioning disc 211, and reposition the included angle between the first connecting rod 21 and the second connecting rod 22.

[0051] Furthermore, such as Figure 4As shown, the positioning component 23 includes a limiting head, a threaded portion, and a plug-in portion that are fixedly connected in sequence. The limiting head, threaded portion, and plug-in portion are coaxially arranged. The threaded portion has an external thread and is located in the positioning threaded hole on the second connecting rod 22. The plug-in portion is used to insert into the positioning connection hole 2111 on the positioning disc 211. The diameter of the plug-in portion is smaller than the diameter of the threaded portion, so that when the positioning component 23 is used to connect the first connecting rod 21 and the second connecting rod 22, the plug-in portion can pass through the positioning threaded hole. In this embodiment, a positioning block 221 is provided on the side of the second connecting rod 22 away from the first connecting rod 21. The positioning threaded hole passes through the positioning block 221. The diameter of the limiting head is larger than the diameter of the threaded portion. When the plug-in portion is inserted into the positioning connection hole 2111, the limiting head abuts against the positioning block 221. The positioning block 221 can extend the length of the positioning threaded hole and improve the connection strength between the positioning component 23 and the second connecting rod 22.

[0052] Optionally, such as Figure 1 and Figure 4 As shown, the positioning assembly 2 also includes a hinge shaft 24, through which the first connecting rod 21 and the second connecting rod 22 are hinged. Specifically, the first connecting rod 21 is provided with a first hinge hole, and the second connecting rod 22 is provided with a second hinge hole 222. The hinge shaft 24 passes through the first hinge hole on the first connecting rod 21 and the second hinge hole 222 on the second connecting rod 22.

[0053] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the abrasion-resistant protective sleeve for offshore wind power cables provided in this embodiment also includes a support assembly 4. The support assembly 4 includes a reinforcing rod 41 and a limiting nut 42. A through hole is provided on the hinge shaft 24, and the axis of the through hole is also the hinge axis between the first connecting rod 21 and the second connecting rod 22. The through holes of the two hinge shafts 24 located on both sides of the third sheath 13 are coaxially arranged. One end of the reinforcing rod 41 passes through the through hole on the hinge shaft 24 located on one side of the third sheath 13 and is exposed on the hinge shaft 24, and the other end passes through the through hole on the hinge shaft 24 located on the other side of the third sheath 13 and is exposed on the hinge shaft 24. The portions of the reinforcing rod 41 exposed on the hinge shaft 24 at both ends are threaded with limiting nuts 42. Through the cooperation of the reinforcing rod 41 and the limiting nut 42, the coaxiality between the two hinge shafts 24 located on both sides of the protective sleeve 1 can be ensured, the relative position between the two positioning discs 211 can be positioned, and the relative rotation between the first connecting rod 21 and the second connecting rod 22 located on both sides of the protective sleeve 1 can be ensured.

[0054] Furthermore, such as Figure 2 and Figure 4As shown, the reinforcing rod 41 includes a U-shaped part and a connecting part. Both ends of the U-shaped part are fixedly connected to the connecting part, and the two connecting parts are respectively inserted into the through holes on the hinge shafts 24 on both sides of the protective sleeve 1. The U-shaped part is used to avoid the third sheath 13, so that the presence of the reinforcing rod 41 will not affect the normal bending of the cable.

[0055] The following is the usage method of the anti-wear protective sleeve for offshore wind power cables provided in this embodiment:

[0056] When laying offshore wind power cables, anti-wear protective sleeves are fitted onto the cables according to the number and location of the bends encountered during cable laying. When the cable is laid to a bend, the angle between the first sheath 11 and the second sheath 12 is adjusted to a suitable angle so that the cable bends at the appropriate angle. The angle between the first connecting rod 21 and the second connecting rod 22 is positioned using the positioning component 23. Then, the first sheath 11 and the second sheath 12 are fixed to the wind turbine tower by the fixing rod 31 on the clamp 3, thereby fixing the cable at the designated position. Through the combined use of the first sheath 11, the second sheath 12, and the third sheath 13, the cable can be effectively protected, avoiding wear on the cable sheath caused by friction during long-term use, thus achieving the protective purpose.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
