Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing devices, and particularly relates to a cable fixing device applicable to a wind turbine blade. Background Art

[0002] To ensure the safe and stable operation of a wind turbine, a variety of monitoring devices are usually installed on the wind turbine blade. Since the wind turbine blade is large in volume and long in length, the cables used to connect to the monitoring devices are also long. Usually, cable fixing clips are used to fix the cables so that the cables are arranged neatly inside the wind turbine blade.

[0003] The cable fixing clips in the related art are fixed on the wind turbine blade by screws. When installing multiple fixing clips, multiple holes need to be drilled in sequence on the wind turbine blade, and then multiple screws need to be screwed in sequence. The operation process is particularly troublesome. Moreover, since the cable installation of the wind turbine blade requires working at heights, the operations of drilling multiple holes and screwing will increase the time of working at heights, resulting in a relatively high construction risk. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to some extent.

[0005] For this reason, an embodiment of the utility model provides a cable fixing device applicable to a wind turbine blade. By bonding the connecting seat to the base body, the rapid installation of the cable fixing device can be realized, the time of working at heights can be reduced, and thus the construction safety can be improved.

[0006] The cable fixing device applicable to a wind turbine blade in the embodiment of the utility model includes a mounting seat. The mounting seat includes a cable fixing seat and a connecting seat for bonding with the base body. The cable fixing seat has a cable groove for the cable to pass through. The mounting seat has a cable tie hole for the cable tie to pass through. The cable tie hole extends along the width direction of the cable groove.

[0007] In some embodiments, the number of the cable tie holes is multiple, and the multiple cable tie holes are arranged at intervals along the length direction of the cable groove.

[0008] In some embodiments, the cable fixing seat includes a convex portion, the convex portion protrudes along the direction away from the connecting seat, and there is a gap between the convex portion and the connecting seat so as to form the cable tie hole between the convex portion and the connecting seat.

[0009] In some embodiments, the cross section of the cable groove is arc-shaped.

[0010] In some embodiments, the dimension of the connecting seat in the length direction of the cable groove is greater than the dimension of the connecting seat in the height direction of the cable groove.

[0011] In some embodiments, the size of the mounting base in the height direction of the wire fixing groove is 6 mm to 10 mm.

[0012] In some embodiments, the size of the connecting base in the length direction of the wire fixing groove is greater than or equal to the size of the wire fixing base in the length direction of the wire fixing groove.

[0013] In some embodiments, the size of the connecting base in the width direction of the wire fixing groove is greater than the size of the wire fixing base in the width direction of the wire fixing groove.

[0014] In some embodiments, the wire fixing base and the connecting base are integrally formed.

[0015] When the wire fixing device applicable to the wind turbine blade in the embodiment of the present utility model is used for the wind turbine blade, the wire can be limited by the wire fixing groove on the wire fixing base, and the wire fixing device can be quickly installed by bonding the connecting base to the base body. Compared with the installation method that requires drilling holes and screwing screws on the blade in the related art, the time of high-altitude operation can be reduced, thereby improving the construction safety.

[0016] In addition, by bonding the wire fixing device to the wind turbine blade, there is no need to drill holes on the wind turbine blade, thereby reducing the structural damage to the wind turbine blade. At the same time, when installing the wire fixing device, the installer can adjust the installation direction of the wire fixing device at will according to the wire routing, which is more conducive to arranging the wires and making the wire arrangement more orderly.

[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0027] As Figures 1 to 3 shown, the wire fixing device 100 applicable to a wind turbine blade according to an embodiment of the present utility model includes a mounting base. The mounting base includes a wire fixing base 1 and a connecting base 2 for bonding with a matrix. The wire fixing base 1 has a wire fixing groove 11 for a cable 200 to pass through. The mounting base has a zip tie hole 12 for a zip tie 300 to pass through. The zip tie hole 12 extends along the width direction of the wire fixing groove 11.

[0028] When the wire fixing device 100 applicable to a wind turbine blade according to an embodiment of the present utility model is used for a wind turbine blade, the cable 200 can be limited by the wire fixing groove 11 on the wire fixing base 1. The zip tie 300 can pass through the zip tie hole 12, and the cable 200 can be further fixed by the zip tie 300 to prevent the cable 200 from loosening from the wire fixing groove 11. By bonding the connecting base 2 with the matrix and further fixing the cable 200 by the zip tie 300, the operation is relatively simple and takes less time, and the quick installation of the wire fixing device 100 can be realized. Compared with the installation method that needs to drill holes and screw in screws on the blade in the related art, the time of working at height can be reduced, thereby improving the construction safety.

[0029] In addition, by bonding the wire fixing device 100 with the wind turbine blade, there is no need to drill holes in the wind turbine blade, which can reduce the structural damage to the wind turbine blade. At the same time, when installing the wire fixing device 100, the installer can freely adjust the installation direction of the wire fixing device 100 according to the running direction of the cable 200, which is more conducive to arranging the cable 200 and making the arrangement of the cable 200 more orderly.

[0030] Optionally, the zip tie 300 is made of a high-strength zip tie made of PA66 material.

[0031] Optionally, as Figure 1 shown, the cable 200 is embedded in the wire fixing groove 11. The side wall of the wire fixing groove 11 can limit the movement of the cable 200 along the width direction of the wire fixing groove 11. The zip tie 300 can limit the movement of the cable 200 along the height direction of the wire fixing groove 11. When the zip tie 300 presses the cable 200, the zip tie 300 can also limit the movement of the cable 200 along the thickness direction of the wire fixing groove 11, thereby firmly fixing the cable 200 on the wire fixing device 100. At the same time, when the zip tie 300 is damaged or the cable needs to be disassembled, the zip tie 300 can be directly cut off and then replaced, and the operation is relatively convenient and the cost is relatively low.

[0032] It is understandable that the base is an installation base for the cable 200, and the base can be a blade of a wind turbine, a wall surface, etc.

[0033] It is understandable that for the convenience of description, the fan blade in this embodiment refers to the blade of a wind turbine.

[0034] In some embodiments, the number of cable tie holes 12 is multiple, and the multiple cable tie holes 12 are arranged at intervals along the length direction of the cable fixing groove 11.

[0035] By providing multiple cable tie holes 12, multiple cable ties 300 can pass through the cable fixing device 100, so that the cable 200 can be fixed at multiple positions along the length direction of the cable 200, making the position of the cable 200 in the cable fixing groove 11 more stable, and thus more conducive to organizing the cable 200.

[0036] Optionally, as Figure 1 and Figure 2 shown, the cable tie holes 12 penetrate the mounting base along the width direction of the cable fixing groove 11 for the cable tie 300 to pass through, and the two ends of the cable tie 300 can be interpenetrated and connected to each other. The number of cable tie holes 12 is two, and the two ends of a section of the cable 200 embedded in the cable fixing groove 11 can be fixed by the two cable ties 300, so that the section of the cable 200 between the two cable ties 300 is in close contact with the groove wall of the cable fixing groove 11 to achieve the fixation of this section of the cable 200; in addition, the two cable tie holes 12 are respectively arranged close to the two ends of the cable fixing groove 11 to maximize the length of the cable 200 in close contact with the groove wall of the cable fixing groove 11, thereby improving the stability of the cable 200.

[0037] In some embodiments, the cable fixing base 1 includes a convex portion 13, the convex portion 13 protrudes along the direction away from the connection base 2, and there is a gap between the convex portion 13 and the connection base 2, so as to form the cable tie hole 12 between the convex portion 13 and the connection base 2.

[0038] When the cable tie 300 fixes the cable 200, the cable tie 300 is in a tensioned state, and the cable tie 300 exerts an extrusion force on the mounting base. If the strength of the mounting base is low, it is easy to cause deformation or damage to the mounting base. Compared with the technical solution of directly opening the cable tie hole 12 on the mounting base, by providing the convex portion 13, the cable tie hole 12 is formed between the convex portion 13 and the connection base 2, which can maintain the thickness of the mounting base at the position of the cable tie hole 12 unchanged, thereby reducing the influence of the setting of the cable tie hole 12 on the strength of the mounting base.

[0039] In some embodiments, the cross-section of the cable fixing groove 11 is arc-shaped.

[0040] By setting the cross-section of the wire fixing groove 11 to be arc-shaped, the groove wall of the wire fixing groove 11 can better match the cable 200, making it more fitting. The groove wall of the wire fixing groove 11 can play a role in limiting the cable 200, making the position of the cable 200 more stable.

[0041] Optionally, the cross-section of the wire fixing groove 11 is one of shapes such as circular arc-shaped, elliptical arc-shaped, etc. Preferably, the cross-section of the wire fixing groove 11 is semi-circular arc-shaped.

[0042] In some embodiments, the dimension of the connecting seat 2 in the length direction of the wire fixing groove 11 is greater than the dimension of the connecting seat 2 in the height direction of the wire fixing groove 11.

[0043] With the above settings, the dimension of the connecting seat 2 in the height direction of the wire fixing groove 11 is smaller, making the wire fixing seat 1 closer to the base body, that is, the cable 200 is closer to the base body, which is more conducive to the layout of the cable 200.

[0044] Optionally, as Figure 2 shown, the dimension of the connecting seat 2 in the width direction of the wire fixing groove 11 is also greater than the dimension of the connecting seat 2 in the height direction of the wire fixing groove 11. It can be understood that the dimension of the connecting seat 2 in the length direction of the wire fixing groove 11 is its length, the dimension of the connecting seat 2 in the width direction of the wire fixing groove 11 is its width, and the dimension of the connecting seat 2 in the height direction of the wire fixing groove 11 is its thickness.

[0045] In some embodiments, the dimension of the mounting seat in the height direction of the wire fixing groove 11 is 6 mm to 10 mm.

[0046] Since the wind turbine blade is flat and its internal space is also flat, in other words, the installation space available for the 100 in the wind turbine blade is limited; the mounting seat is used to assist the cable 200 to be neatly arranged inside the wind turbine blade. It can be understood that the height direction of the wire fixing groove 11 is the thickness direction of the wind turbine blade. By restricting the dimension of the mounting seat in the height direction along the wire fixing groove 11, that is, restricting the thickness of the mounting seat, it is more conducive to the installation of the mounting seat inside the wind turbine blade, thus facilitating wiring in the flat space of the blade.

[0047] Preferably, the dimension of the mounting seat in the height direction of the fixing groove (i.e., the thickness of the mounting seat) is 8 mm.

[0048] In some embodiments, the dimension of the connecting seat 2 in the length direction of the wire fixing groove 11 is greater than or equal to the dimension of the wire fixing seat 1 in the length direction of the wire fixing groove 11.

[0049] It can be understood that the surface of the connecting seat 2 away from the wire fixing seat 1 is the bonding surface 21. The connecting seat 2 is bonded to the base through the bonding surface 21. By making the dimension of the connecting seat 2 in the length direction of the wire groove 11 greater than or equal to the dimension of the wire fixing seat 1 in the length direction of the wire groove 11, the length of the bonding surface 21 can be increased, thereby increasing the fitting area between the connecting seat 2 and the base, and making the bonding between the wire fixing device 100 and the base firm.

[0050] In some embodiments, the dimension of the connecting seat 2 in the width direction of the wire groove 11 is greater than the dimension of the wire fixing seat 1 in the width direction of the wire groove 11.

[0051] Through the above settings, the width of the bonding surface 21 can be increased, thereby further increasing the fitting surface between the connecting seat 2 and the base, and making the bonding between the wire fixing device 100 and the base more firm.

[0052] In some embodiments, the wire fixing seat 1 and the connecting seat 2 are integrally formed.

[0053] By integrally forming the wire fixing seat 1 and the connecting seat 2, the production and processing of the wire fixing device 100 are made more convenient, and at the same time, the connection strength between the wire fixing seat 1 and the connecting seat 2 is also higher.

[0054] The wind turbine of the embodiment of the present utility model includes a blade and a wire fixing device 100. The wire fixing device 100 is the wire fixing device 100 of any of the above embodiments, and the connecting seat 2 is bonded to the blade.

[0055] During the construction process of the wind turbine, by bonding the connecting seat 2 to the blade, the rapid installation of the wire fixing device 100 and the wiring speed of the cable 200 can be achieved, thereby reducing the time of high-altitude operation and improving the construction safety.

[0056] Optionally, the connecting seat 2 is made of fiberglass. Since the wind turbine blade is made of fiberglass, by making the connecting seat 2 and the blade of the same material, the bonding between the connecting seat 2 and the blade can be made more firm.

[0057] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present utility model.
