Description

Technical Field

[0001] This invention relates to the field of cable fixing, and in particular to a cable routing fixing structure inside a wind turbine nacelle. Background Technology

[0002] Wind power generation, as a clean and renewable energy technology, has been widely used globally. Wind turbines, especially large wind turbines, have complex internal structures within their nacelles, containing numerous critical components such as generators, gearboxes, frequency converters, and control systems. These components require extensive cabling for power transmission and signal control. Therefore, the cable layout and management within the nacelle (i.e., cable routing) directly affects the reliability, safety, and ease of maintenance of the entire wind turbine operation.

[0003] A wind turbine nacelle cable fixing device with existing patent application number 201922146289.9 includes a connecting plate, a plurality of springs connected between the connecting plate and a first fixing seat, a plurality of first arc-shaped grooves spaced apart on the upper surface of the first fixing seat, a plurality of second fixing seats stacked on the upper end of the first fixing seat, a plurality of second arc-shaped grooves symmetrically opened on the upper and lower surfaces of the second fixing seats, and fixing bolts passing downward through the first through holes opened at both ends of the plurality of second fixing seats and screwed into the first threaded through holes opened at both ends of the first fixing seat;

[0004] Existing fixed structures are mostly fixed installations, which mix cables of different specifications and functions together. This is not only unsightly, but also brings great difficulties to later inspection, maintenance and replacement. In addition, the lack of a proper fixed structure makes the cables prone to swinging back and forth, causing wear and tear. There is also a lack of effective layered and classified fixing measures. Furthermore, the cables may condense due to temperature changes, leading to increased humidity. A humid environment will accelerate the aging and corrosion of cable joints and the cable body. Therefore, a cable routing and fixing structure for wind turbine nacelles is proposed. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the existing defects and provide a cable routing and fixing structure for wind turbine nacelles. Adjustable side frames, in conjunction with placement racks, allow for the installation of different numbers of cable racks, enabling the separation and layering of different types of cables. This easily adapts to different cable layouts and nacelle space. Simultaneously, the screw-adjustable clamping plate, along with main and auxiliary protective pads, ensures cable fixation and prevents wear under vibration. Furthermore, the integrated dehumidification box prevents moisture corrosion and extends cable life, effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable routing and fixing structure inside a wind turbine nacelle, comprising a fixing frame and an adjustment unit:

[0007] Fixed frame: Adjustment grooves are provided on both sides inside;

[0008] Adjustment unit: includes side frame, adjustment rod, slide groove, placement frame, slider, mounting groove, cable rack, and mounting block. There are two adjustment rods, each slidably installed in a corresponding adjustment groove. Side frames are fixed to the outer ends of both adjustment rods. Slide grooves are formed on the surface of the side frames. Sliders are fixed to both sides of the placement frame, slidably installed in the corresponding slide grooves. Screw holes are formed on the outer surface of the sliders. Mounting grooves are formed on both sides of the inner bottom surface of the placement frame. A mounting block is fixed to the center of the bottom surface of the cable rack, slidably inserted into the mounting groove. Anti-detachment holes are formed on the surface of the mounting block. A fixing unit is provided on the bottom surface of the cable rack. A dehumidification unit is provided on the surface of the side frame.

[0009] It also includes connecting plates and fixing bolts. There are four connecting plates, which are fixed in pairs on the front and back sides of the fixing frame. Fixing bolts are inserted into the through holes on the surface of the connecting plates.

[0010] The adjusting rod slides inside the adjusting groove to adjust the distance between the two side frames for the installation of placement racks of different specifications, while the slider slides inside the sliding groove to adjust the height of the placement rack. The mounting block is inserted into the mounting groove to install multiple cable racks, thereby facilitating the classification and layering of cables.

[0011] Furthermore, the adjustment unit also includes a spring groove, a spring, a pressure plate, locking holes, and locking rods. The spring groove is located in the middle of the bottom surface of the fixed frame, and a spring is fixed inside the spring groove. The bottom end of the spring is connected to the middle of the top surface of the pressure plate. Locking rods are installed on both the left and right sides of the top surface of the pressure plate. The locking holes are evenly distributed on the bottom surface of the adjustment rods. When the spring contracts, the locking rods on the top surface of the pressure plate are inserted into the locking holes, thereby locking the position of the adjustment rods.

[0012] Furthermore, the adjustment unit also includes a toothed groove, a fixed tooth, a fixing plate, and bolts. The toothed groove is evenly opened on the front and rear sides of the side frame. Bolts are inserted into the through holes on the surface of the fixing plate. The bolts are threadedly fitted with the screw holes on the outer side of the slider. Fixed teeth corresponding to the toothed grooves are fixed at both ends of the inner side of the fixing plate. Rotating the bolts will engage the fixed teeth on the inner side of the fixing plate into the toothed grooves, thereby fixing the placement frame.

[0013] Furthermore, the adjustment unit also includes a limiting groove and a limiting rod. There are two limiting grooves, which are respectively opened in the middle of the front and rear sides of the fixed frame. There are two limiting rods, which are fixed to the top surface of the pressure plate in a front-to-back manner. The limiting rods are slidably installed with the limiting grooves, and the limiting rods slide inside the limiting grooves to increase the stability of the pressure plate adjustment.

[0014] Furthermore, the fixing unit includes a pressure plate, a bracket, a support plate, a screw, and a rotating wheel. The screw is rotatably mounted on the bottom surface of the mounting block, and a rotating wheel is fixed to the bottom end of the screw. The screw is threadedly connected to a screw hole on the surface of the support plate. Brackets are fixed on both sides of the top surface of the support plate. The brackets are slidably mounted to the bracket grooves on the side of the cable frame. The top ends of the two brackets are respectively connected to the left and right sides of the pressure plate. The pressure plate is slidably mounted inside the cable frame. Rotating the rotating wheel drives the screw to rotate, thereby pressing down the pressure plate connected to the bracket to press and fix the cable tightly inside the cable frame, preventing damage caused by the cable shaking and friction. At the same time, it greatly enhances the reliability of cable fixing under the vibration environment of the fan.

[0015] Furthermore, the fixing unit also includes a connecting groove, a connecting block, a plug plate, an anti-detachment groove, and a cable trough. There are four connecting grooves, which are arranged in pairs on both sides of the top surface of the cable rack. Both sides of the end of the cable trough are provided with connecting blocks that are inserted into the connecting grooves. An anti-detachment groove is provided on the bottom surface inside the cable trough. A plug plate is slidably installed inside the anti-detachment groove. The plug plate is inserted into a slot on the side of the cable rack. The connecting block is inserted into the connecting groove to install the cable trough and the cable rack. The plug plate that slides inside the anti-detachment groove is inserted into the slot to increase the stability of the connection between the cable trough and the cable rack. This can provide a sealed protection for the cable.

[0016] Furthermore, the fixing unit also includes a fixing base, mounting holes, mounting bolts, and an anti-detachment rod. The fixing base is fixed to the middle of the bottom surface of the placement frame. Mounting holes are provided on both the left and right sides of the fixing base. Mounting bolts are provided on the inner side of the anti-detachment rod. The mounting bolts are threaded into the mounting holes. The anti-detachment rod is inserted into the anti-detachment holes on the surface of the mounting block. The mounting bolts are threaded into the mounting holes to insert the anti-detachment rod into the anti-detachment holes on the surface of the mounting block, thereby fixing the position of the cable rack to prevent it from falling off.

[0017] Furthermore, the fixing unit also includes a main protective pad and a secondary protective pad. The main protective pad is bonded to the bottom surface of the pressure plate, and the secondary protective pad is bonded to the bottom surface inside the cable rack. Both the main protective pad and the secondary protective pad are rubber pads. The main protective pad and the secondary protective pad can increase friction to improve the firmness of the cable fixing, while buffering pressure to prevent the cable sheath from being pinched or worn.

[0018] Furthermore, the dehumidification unit includes a fixed rod, a rod frame, a box slot, a vent, a sealing plate, and a dehumidification box. There are two box slots, each located at the top of the front side of the two side frames. A vent is provided on one side of each box slot. The dehumidification box is slidably installed in the box slot. The front end of the dehumidification box is connected to the rear side of the sealing plate. The rod frame is fixed to the front side of the side frame. A fixed rod is slidably inserted into the rod hole in the middle of the rod frame. The fixed rod inside the rod frame secures the slidably installed dehumidification box. The desiccant inside the dehumidification box exchanges with the surrounding air through the vent, which can effectively absorb moisture near the cable fixing area, reduce the risk of condensation, and delay the corrosion and aging of the cable and connector.

[0019] Furthermore, it also includes an identification frame and an information card. The identification frame is fixed to the top surface of the pressure plate, and the information card is inserted and installed inside the identification frame. The information card inside the identification frame can be used to record information such as the number, model and function of the fixed cable. Maintenance personnel can quickly identify the target cable without having to look through complicated drawings, which significantly shortens the troubleshooting and repair time.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The cable routing and fixing structure inside the wind turbine nacelle has the following advantages:

[0021] 1. The distance between the two side frames is adjusted by sliding the adjusting rod inside the adjusting groove to install placement frames of different specifications to meet the cable laying requirements of different lateral spacing. The height of the placement frame is adjusted by sliding the slider inside the sliding groove to achieve longitudinal position adjustment of the cable fixing point. The mounting block is inserted into the mounting groove to install multiple cable racks, thereby facilitating the classification and layering of cables.

[0022] 2. By rotating the wheel to drive the screw to rotate, the clamping plate connected to the bracket is pressed down to press and fix the cable inside the cable rack, so as to prevent the cable from shaking and rubbing back and forth and causing damage. At the same time, it greatly enhances the reliability of the cable fixation in the environment of fan vibration. The mounting bolts and mounting hole threads are used to insert the anti-detachment rod into the anti-detachment hole on the surface of the mounting block, thus fixing the position of the cable rack and preventing it from falling off.

[0023] 3. The cable tray and cable rack are installed by inserting the connecting block into the connecting groove, and the sliding insert plate inside the anti-detachment groove is inserted into the slot to increase the stability of the connection between the cable tray and the cable rack, which can play a role in sealing and protecting the cable.

[0024] 4. The sliding dehumidifier box is fixed by the fixing rod inside the frame. The desiccant inside the dehumidifier box exchanges air with the surrounding air through the vent, which can effectively absorb moisture near the cable fixing area, reduce the risk of condensation, and delay the corrosion and aging of cables and joints.

This facilitates the classification and layering of cables. Then, rotating the wheel 35 drives the screw 34 to rotate, thereby fixing the bracket 3... The pressure plate 31 connected to the cable rack 27 is pressed down to secure the cable tightly inside the cable rack 27. This, along with the main protective pad 315 and secondary protective pad 316, prevents damage caused by the cable's back-and-forth movement and friction. It also greatly enhances the reliability of the cable's fixation under fan vibration. The connecting block 37 is inserted into the connecting groove 36 to install the cable tray 310 with the cable rack 27.
