Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an easy-to-install cable for wind power generation. Background Art

[0002] The cables are arranged from top to bottom in the wind turbine tower. These cables need to be led out from the nacelle, pass through the tower, and finally connected to the electrical cabinet at the bottom of the tower. There are many cables and they are long. Therefore, it is necessary to guide and fix the cables while preventing them from sliding down.

[0003] The existing announcement number is CN208015268U, and the name is a wind turbine cable clamp, which includes a first cable clamp block, a connecting seat is welded on both sides of the left and right sides of the first cable clamp block, a screw is inserted at the top of the connecting seat, a spring is sleeved on the outer wall of the bottom end of the screw, a pressure ring is installed at the top of the spring, a collar is welded on the top of the pressure ring, a connecting rod is inserted at the center position of the collar, a pressure plate is welded at the bottom end of the connecting rod, a second cable clamp block is welded at the bottom end of the pressure plate, a placement groove is opened in the gap between the lower surface of the second cable clamp block and the upper surface of the first cable clamp block, and the top of the screw is provided with a pressure plate. The outer wall of the end is threadedly connected with a fixing nut. The wind turbine cable clamp is constructed by placing the bottom of the cable in the placement groove opened on the upper surface of the first cable clamp block, rotating the fixing nut downward, and the fixing nut moves downward on the screw rod. When the fixing nut contacts the ring, the ring is pushed to drive the pressure ring pressure spring to retract and retract downward. At the same time, the ring drives the connecting rod and the pressure plate downward, and the pressure plate drives the second cable clamp block downward. The second cable clamp block fixes the top of the cable line, ensuring that the cable is easily fixed, reducing the labor of the installer and improving the efficiency of installation.

[0004] However, the cable clamps clamp the cable horizontally, and the interior of the existing tower is cylindrical. When the cable clamp is installed inside the tower, the installation stability is poor. The cable clamped by the cable clamp moves vertically downward, and the cable is hung vertically inside the tower, which is prone to entanglement, making it inconvenient to install the power generation cable later.

[0026] like Figures 1 to 5As shown, a cable for wind power generation that is easy to install includes a hanging part 1 and a wire harness part 2. The hanging part 1 includes a hanging plate 11. A plurality of plug-in frames 12 are evenly and vertically fixed on the outer end surface of the hanging plate 11. The plurality of plug-in frames 12 are horizontally threaded and assembled with locking bolts 13. The plurality of plug-in frames 12 are horizontally assembled with wire harness parts 2. The wire harness part 2 includes a screw hole bracket 21. Both ends of the screw hole bracket 21 are horizontally penetrated to provide screw holes. The screw hole bracket 21 has a plurality of holes. One end of the bracket 23 is inserted into the insertion frame 12, and the screw hole at one end of the screw hole bracket 21 is threadedly assembled with the locking bolt 13. A bracket 23 is horizontally provided at the other end of the screw hole bracket 21, and a cable drum 25 is vertically passed through and fixed in the middle of the bracket 23. The cable drum 25 is used to clamp and pass through the installation cable. A through hole is horizontally passed through the end of the bracket 23 away from the screw hole bracket 21, and a pressure frame 28 is slidably assembled in the through hole of the bracket 23. The middle of the upper and lower end surfaces of the lifting plate 11 are The cam 14 is fixed vertically, and the upper and lower sides of the lifting plate 11 are vertically provided with a lifting rope 15. The two ends of the lifting rope 15 are vertically fixed with a stud 16, and the stud 16 is threadedly assembled in the cam 14. When the cable for wind power generation is vertically supported in the wind turbine tower during use, the lifting plates 11 in the multiple lifting parts 1 are arranged in the vertical direction, and the multiple lifting plates 11 in the multiple lifting parts 1 are threadedly assembled in the cam 14 of the lifting plate 11 through the studs 16 at the ends of the lifting rope 15, and are lifted together in the vertical direction. Then the cable for wind power generation is passed through the bundle drum 25, and at the same time, the sliding bracket 23 slides horizontally outward on the screw hole bracket 21 to disperse the load and support the cable for wind power generation in the tower, and then disperse the support cable for wind power generation, thereby avoiding the problem that the cable is vertically suspended inside the tower, which is easy to get entangled and inconvenient to install the power generation cable in the later stage, and is convenient to ensure the stability of the cable suspension.

[0027] In one embodiment, Figure 2 and 4 As shown, an adjusting screw 22 is assembled through a horizontal thread in the screw hole of the screw hole bracket 21 at the end away from the hanging plate 11, and a hole seat 211 is fixed to the bottom of the end of the screw hole bracket 21 away from the hanging plate 11, and a guide rod 24 is horizontally fixed to one end of the bracket 23, and the guide rod 24 is horizontally slidably assembled in the hole seat 211, and the end of the adjusting screw 22 is rotatably connected to the bracket 23.

Then, the cable for wind power generation is passed through the cable bundle 25, and at the same time, the sliding bracket 23 slides horizontally outward on the screw hole bracket 21 to disperse the load and support the cable for wind power generation in the tower.

[0031] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or modifications made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
