Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a corrosion-resistant cable fixing device for offshore wind turbines. Background Technology

[0002] Offshore wind turbines are power generation devices specifically designed to convert wind energy into electrical energy in marine environments. They mainly consist of core components such as a wind turbine system, a transmission system, and a power generation system, and are characterized by their adaptability to harsh marine environments and high-efficiency power generation. When a wind turbine generates electricity, the generated power needs to be transmitted through cables. However, because wind turbines are located at sea, these cables are easily affected by sea winds and waves, causing them to sway. Therefore, it is necessary to secure the cables. Existing cables are usually secured using cable clamps.

[0003] The existing cable clamps require the cable to be placed into the arc-shaped groove of the lower clamp block, then the upper clamp block is attached to the cable surface, and finally the upper and lower clamp blocks are connected and fixed with bolts. This makes fixing the cable cumbersome, and the bolts are prone to falling off during installation, affecting the cable fixation. Therefore, improvements are needed. Utility Model Content

[0058] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a corrosion-resistant cable fixing device for offshore wind turbines.

[0059] A corrosion-resistant cable fixing device for offshore wind turbines includes: an upper clamping block 1 for clamping and fixing the cable; a lower clamping block 2 disposed below the upper clamping block 1; a support groove 3 formed on the upper clamping block 1; a support block 4 disposed on the upper clamping block 1 and fixedly connected to the upper clamping block 1; a support hole 5 formed on the support block 4; a clamping mechanism disposed on the lower clamping block 2 for clamping and fixing the upper clamping block 1; two fixing blocks 6, which are symmetrically arranged in the support hole 5 and slidably connected to the support hole 5; a support plate 7 fixedly connected to the fixing blocks 6; and a pressing mechanism disposed on the upper clamping block 1 for pressing and fixing the cable.

[0060] Reference Figure 4 In a preferred embodiment, the clamping mechanism includes: two clamping blocks 8, which are symmetrically arranged on the lower clamping block 2 and fixedly connected to the lower clamping block 2; a clamping shaft 9, which is rotatably connected to the clamping blocks 8; a clamping disc 10, which is fixedly connected to the clamping shaft 9; and a sliding component disposed within the clamping blocks 8.

[0061] During operation, rotating the clamping disk 10 causes the clamping shaft 9, which is fixedly connected to the clamping disk 10, to rotate on the clamping block 8.

[0062] Reference Figure 4 In a preferred embodiment, the sliding component includes: a sliding groove 11, which is formed on the clamping block 8; two sliding blocks 12, which are symmetrically arranged in the sliding groove 11 and slidably connected to the sliding groove 11; and an elastic component, which is disposed on the sliding block 12.

[0063] During operation, the sliding block 12, which is threadedly connected to the clamping shaft 9, rotates, causing the sliding block 12 to slide within the sliding groove 11.

[0064] Reference Figure 4In a preferred embodiment, the elastic component includes: an elastic frame 13, disposed on the sliding block 12 and fixedly connected to the sliding block 12; an elastic groove 14, formed inside the elastic frame 13, and the support plate 7 is slidably connected to the elastic groove 14; and multiple elastic springs 15, which are evenly disposed inside the elastic groove 14, fixedly connected to the elastic frame 13, and fixedly connected to the support plate 7.

[0065] During operation, the elastic frame 13, which is fixedly connected to the sliding block 12, moves closer to each other. As the elastic frame 13 moves, it pulls the support plate 7, causing the support plate 7 to slide in the elastic groove 14. This stretches the elastic spring 15, which is fixedly connected to the support plate 7, generating elastic potential energy. This causes the fixed block 6 to move closer to the support block 4 until the fixed block 6 and the support hole 5 are completely overlapped.

[0066] Reference Figure 5 and Figure 6 In a preferred embodiment, the extrusion mechanism includes: an extrusion shaft 16, which is disposed on the upper clamping block 1 and rotatably connected to the upper clamping block 1; an extrusion block 17, which is fixedly connected to the extrusion shaft 16; and a moving component disposed inside the upper clamping block 1.

[0067] During operation, rotating the extrusion block 17 causes the extrusion shaft 16, which is fixedly connected to the extrusion block 17, to rotate on the upper clamping block 1.

[0068] Reference Figure 5 and Figure 6 In a preferred embodiment, the moving component includes: a moving groove 18, which is opened in the upper clamping block 1; two moving blocks 19, which are symmetrically arranged in the moving groove 18, slidably connected to the moving groove 18, and threadedly connected to the extrusion shaft 16; and a rotating component, which is disposed on the moving blocks 19.

[0069] During operation, the moving block 19, which is threadedly connected to the extrusion shaft 16, rotates, causing the moving block 19 to slide within the moving groove 18.

[0070] Reference Figure 6 In one preferred embodiment, the rotating component includes: a first rotating shaft 20, which is disposed on the movable block 19 and fixedly connected to the movable block 19; a rotating plate 21, which is rotatably connected to the first rotating shaft 20; a second rotating shaft 22, which is rotatably connected to the rotating plate 21; a rotating frame 23, which is disposed on the second rotating shaft 22 and fixedly connected to the second rotating shaft 22; and a rotating block 24, which is fixedly connected to the rotating frame 23 and slidably connected to the support groove 3.

[0071] During operation, the rotating plate 21, which is rotatably connected to the first rotating shaft 20, rotates, causing the rotating frame 23, which is fixedly connected to the second rotating shaft 22, to move closer to the downward clamping block 2, so that the rotating block 24, which is fixedly connected to the rotating frame 23, slides in the support groove 3 until the rotating block 24 is in contact with the surface of the cable.

[0072] Working principle: In use, first place the cable into the groove of the lower clamping block 2, then place the groove of the upper clamping block 1 onto the surface of the cable, so that it is in contact with the surface of the cable. Then rotate the clamping disk 10, which drives the clamping shaft 9 fixedly connected to the clamping disk 10 to rotate on the clamping block 8, so that the sliding block 12 threadedly connected to the clamping shaft 9 rotates, and drives the sliding block 12 to slide in the sliding groove 11, so that the elastic frame 13 fixedly connected to the sliding block 12 moves closer to each other. While the elastic frame 13 moves, it pulls the support plate 7, which drives the support plate 7 to slide in the elastic groove 14, so that the elastic spring 15 fixedly connected to the support plate 7 is stretched, generating elastic potential energy, which drives the fixing block 6 to move closer to the support block 4 until the fixing block 6 and the support hole 5 are completely overlapped, thereby achieving the clamping and fixing of the cable.

[0073] Next, rotating the extrusion block 17 causes the extrusion shaft 16, which is fixedly connected to the extrusion block 17, to rotate on the upper clamping block 1. This causes the moving block 19, which is threadedly connected to the extrusion shaft 16, to rotate and slide within the moving groove 18. This causes the rotating plate 21, which is rotatably connected to the first rotating shaft 20, to rotate and cause the rotating frame 23, which is fixedly connected to the second rotating shaft 22, to move closer to the lower clamping block 2. This causes the rotating block 24, which is fixedly connected to the rotating frame 23, to slide within the support groove 3 until the rotating block 24 is in contact with the surface of the cable. This achieves the extrusion and fixation of the cable, preventing the cable from shaking or moving.

[0074] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
