Description

Technical Field

[0001] This utility model relates to the technical field of cable fixing, and in particular to a wind turbine cable fixing device. Background Technology

[0002] With the rapid development of renewable energy technologies, wind power, as an important component of clean energy, has been widely used globally. Wind turbines operate in complex environments characterized by high altitudes, strong winds, and frequent vibrations. The safety and stability of each component significantly impacts the overall operating efficiency and lifespan of the turbine. Among these components, cables, as the key carrier of power transmission, bear the responsibility of transmitting energy and signals from the generator to the tower and control system; therefore, their securing and protection are particularly critical.

[0003] Currently, the most common cable fixing methods used in wind turbines involve simple clamp structures or metal clips for binding and securing. While these structures can achieve cable positioning to some extent, they have many shortcomings in practical applications. For example, traditional clamping structures have a small clamping area, which can easily cause localized stress concentration on the cable, leading to insulation wear or even core wire breakage. In addition, due to the continuous vibration during wind turbine operation, if the clamping is not secure or lacks anti-loosening design, cable slippage or displacement can easily occur, potentially causing serious safety accidents such as short circuits and power outages.

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides a wind turbine cable fixing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a wind turbine cable fixing device, comprising:

[0007] The installation mechanism is equipped with multiple fixing mechanisms;

[0008] Fixed mechanisms include:

[0009] The mounting component is installed on the mounting mechanism, and a positioning arc groove is provided at the bottom of the mounting component.

[0013] Furthermore, the installation mechanism includes:

[0014] The mounting base has at least two slide rails at the top, and the two slide rails are arranged in parallel.

[0015] The movable component is mounted on the mounting base via a slide rail and slides along the length of the slide rail. Multiple fixing mechanisms are mounted on the movable component at equal intervals.

[0016] The adjustment mechanism, installed on the mounting base, is used to move multiple fixed mechanisms to adjust their positions, thereby tightening the clamped cable.

[0017] Furthermore, the regulatory body includes:

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, an embodiment of the present invention provides a wind turbine cable fixing device, comprising:

[0035] The installation mechanism 1 is the basic load-bearing structure of the entire cable fixing device, and it is equipped with multiple fixing mechanisms 2 for clamping and fixing the cable.

[0036] Fixed mechanism 2 includes:

[0037] Mounting component 21 is installed on mounting mechanism 1, and a positioning arc groove is provided at the bottom end of mounting component 21;

[0038] The clamping member 22 is slidably installed in the inner groove of the mounting member 21. The clamping member 22 and the positioning groove of the mounting member 21 are provided with an arc groove. The mounting member 21 and the clamping member 22 cooperate to clamp the cable.

[0039] The threaded rod 23 is rotatably installed in the threaded through hole of the mounting part 21, and the threaded rod 23 is rotatably connected with the clamping part 22.

[0040] Nut 24 is connected to threaded rod 23 and is used to lock the connection position between threaded rod 23 and mounting part 21.

[0041] By adopting the above technical solution, the positioning arc groove of the mounting part 21 and the arc groove of the clamping part 22 cooperate to form a wrap-around clamping that fits the shape of the cable, increases the contact area to disperse pressure, and avoids damage to the cable due to excessive local stress. The threaded rod 23 is rotatably installed in the threaded through hole of the mounting part 21 and cooperates with the clamping part 22. By rotating the threaded rod 23, the clamping part 22 can be driven to slide along the inner groove of the mounting part 21, accurately adjust the clamping distance, adapt to cables of different diameters, and improve the versatility of the device. The nut 24 cooperates with the threaded rod 23 to lock the connection position, prevent the vibration of the wind turbine during operation from causing the threaded rod 23 to loosen, and ensure the stability of the clamping state. Multiple fixing mechanisms 2 can clamp and fix multiple cables at the same time.

[0042] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the installation mechanism 1 includes:

[0043] The mounting base 11 has at least two slide rails 12 at its top, and the two slide rails 12 are arranged in parallel.

[0044] The movable component 13 is mounted on the mounting base 11 via the slide rail 12 and slides along the length of the slide rail 12. Multiple fixing mechanisms 2 are mounted on the movable component 13 at equal intervals.

[0045] Adjustment mechanism 14 is installed on mounting base 11. Adjustment mechanism 14 is used to move multiple fixing mechanisms 2 to adjust the position of moving part 13 so as to tighten the clamped cable.

[0046] In this embodiment, the mounting base 11 serves as the basic load-bearing structure. At least two parallel slide rails 12 at its top provide stable sliding guidance for the moving part 13, ensuring that the moving part 13 drives multiple fixing mechanisms 2 to move smoothly along the length of the slide rails 12, avoiding deviation. The multiple fixing mechanisms 2 installed at equal intervals on the moving part 13 can adjust their positions synchronously with it. In conjunction with the adjustment mechanism 14, the clamped cable can be tightened to eliminate cable slack, reduce cable swaying and wear caused by vibration during wind turbine operation, and improve the adaptability of the device to complex cable layout scenarios. Through tightening operation and stable guidance, the reliability of cable fixing is further guaranteed, and the service life of wind turbine cable is extended.

[0047] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the adjustment mechanism 14 includes:

[0048] Two limiting members 14a are symmetrically installed on the mounting base 11, and the two limiting members 14a are respectively located at both ends of the moving trajectory of the moving member 13;

[0049] The lead screw 14b is rotatably mounted on two limit members 14a, and the lead screw 14b is connected to the threaded inner hole of the moving member 13.

[0050] One end of the lead screw 14b is configured as a regular polygonal structure 14c;

[0051] In this embodiment, two limiting members 14a are symmetrically installed on the mounting base 11 and located at both ends of the moving trajectory of the moving member 13, effectively limiting the sliding range of the moving member 13, preventing it from derailing, and ensuring the safety of the structure operation. The lead screw 14b is rotatably installed on the limiting member 14a and engages with the threaded inner hole of the moving member 13, converting the rotational motion into linear displacement. By precisely controlling the rotation angle of the lead screw 14b, the moving member 13 can be finely adjusted, thereby precisely tightening the cable and eliminating slack. The regular polygonal structure 14c at one end of the lead screw 14b provides a reliable point of force for external tools, making it easy for operators to quickly rotate the lead screw 14b using tools such as wrenches, simplifying the adjustment process and improving the ease of operation. The lead screw 14b can also be installed with a drive motor to increase the rotational force of the lead screw 14b.

[0052] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the mounting base 11 is provided with multiple through holes for bolts 15 to pass through in order to fix the mounting base 11.

[0053] The through hole is designed as a stepped groove structure, so that when the bolt 15 is fixed to the mounting base 11, the bolt 15 is located inside the through hole;

[0054] In this embodiment, multiple through holes on the mounting base 11 allow bolts 15 to pass through to achieve a stable fixation to the wind turbine-related structure, ensuring the installation stability of the entire cable fixing device. The stepped groove structure of the through holes can accommodate the head of the bolt 15 inside the through holes when the bolt 15 is fixed to the mounting base 11, preventing the bolt 15 from protruding from the surface of the mounting base 11 and forming a protrusion, thus preventing obstruction to the sliding of the moving part 13.

[0055] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, protective pads 25 are respectively provided in the positioning groove of the mounting component 21 and the arc groove of the clamping component 22. The protective pads 25 are used to increase the friction force for clamping the cable.

[0056] In this embodiment, the protective pads 25 in the positioning groove of the mounting component 21 and the arc groove of the clamping component 22 can increase the coefficient of friction with the cable surface through the frictional characteristics of their own material, thereby improving the clamping stability of the cable and preventing the cable from sliding at the clamping point when the wind turbine is running. At the same time, the protective pads 25 have a certain degree of elasticity and can form a flexible wrap around the cable shape when clamping, avoiding direct contact between the rigid structure of the mounting component 21 and the clamping component 22 and the cable, which would cause wear on the insulation layer or damage to the outer skin. This provides a buffering and protective function, which not only enhances the reliability of clamping and fixing, but also effectively protects the cable, extends the cable's service life, and meets the cable fixing requirements in the complex operating environment of the wind turbine.

[0057] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, an adjusting cap 26 is provided at the end of the threaded rod 23, and the edge of the adjusting cap 26 is provided with an anti-slip structure;

[0058] In this embodiment, the adjusting cap 26 at the end of the threaded rod 23 provides a convenient point of force application for the operator to rotate the threaded rod 23. Combined with the anti-slip structure on its edge, it can increase the friction between the hand and the adjusting cap 26, avoiding slippage during operation. This allows the operator to easily rotate the threaded rod 23 without additional tools, enabling precise adjustment of the clamping force of the clamping component 22 on the cable. Especially in environments with limited space, such as inside a wind turbine nacelle, or where hands are easily contaminated with oil, the anti-slip structure can ensure the stability and efficiency of the adjustment operation, improve the ease of use of the fixing mechanism 2, and facilitate quick locking or unlocking of the cable clamping state, further ensuring the reliability and flexibility of cable fixing.

[0059] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
