[0026] This application proposes a wind turbine blade root wiring bracket, referring to Figure 1 , including a "J"-shaped curved beam 1, an axis arm 2, a rolling sleeve 3 and a mounting hole 4; the "J"-shaped curved beam 1 is used for routing and fixing the blade root cable; the "J"-shaped curved beam 1 is a symmetrical structure to adapt to blade roots of different sizes and shapes, ensuring that the cables can pass through neatly and orderly. High-strength and lightweight materials are used to improve the bearing capacity and durability of the routing bracket. One end of the axis arm 2 is fixedly installed above the "J"-shaped curved beam 1; the axis arm 2 is centrally fixedly assembled with the "J"-shaped curved beam 1. The rolling sleeve 3 can be rotatably arranged at the other end of the axis arm 2; one end of the blade root cable is wound around the rolling sleeve 3, and there is no relative displacement between the blade root cables and the blade root cables, and between the blade root cables and the "J"-shaped curved beam 1; the mounting holes 4 are arranged at the bottom of both ends of the "J"-shaped curved beam 1, which are used for the fixed installation of the "J"-shaped curved beam 1 to ensure that the bracket is firmly installed.

[0027] In some of the embodiments, a cable fixing plate 5 is provided on one side of the "X"-shaped curved beam 1 and extends upward. The cable fixing plate 5 is provided with a plurality of waist-shaped holes 6 for fixing blade root cables.

[0028] In some of the embodiments, a wire binding ring 7 is provided at one end of the shaft arm 2 away from the "X"-shaped curved beam 1 , and the blade root cable passes through the wire binding ring 7 .

[0029] In some of the embodiments, back plates 8 are provided at both ends of the I-shaped curved beam 1, and bolt holes adapted to the mounting holes 4 are provided on the back plates 8. The I-shaped curved beam 1 is installed by fastening with bolts, and is installed through the back plates 8, thereby ensuring that the wiring bracket is installed firmly and with uniform force.

[0030] In some of the embodiments, the "X"-shaped curved beam 1 is provided with a reinforcing rib plate near the mounting hole 4 .

[0031] In some of the embodiments, a rolling bearing is provided on the shaft arm 2, and the rolling sleeve 3 is sleeved on the rolling bearing.

[0033] In some of the embodiments, the shaft arm 2 is fixedly connected to the X-shaped curved beam 1 by bolts.

[0034] The beneficial effects of the blade root wiring bracket of the wind turbine generator set in this application are as follows:

[0035] The cable routing bracket adopts a reasonable structure and design, making the layout of cables at the root of the blade more orderly and neat. This not only reduces the confusion and crossing of cables, but also facilitates the maintenance and repair work of the staff, greatly improving the efficiency of cable management.

[0036] The cable support is made of high-strength material with excellent load-bearing capacity and durability, which can effectively fix the cables to prevent them from shaking, falling off or wearing during the operation of the wind turbine. This greatly enhances the safety of the cables and reduces the downtime and maintenance costs caused by cable failures.

[0037] By improving the layout and management of cables, the cable routing bracket helps reduce the interference and resistance of cables to the operation of wind turbines, thereby improving the operating efficiency and performance of the generators. At the same time, the orderly cable layout also helps to reduce the heat generated by cable friction, further improving the reliability and stability of the generators.

[0038] Since the cable support has the characteristics of simple structure and convenient installation, it is more convenient to maintain and replace cables during the operation of wind turbines. This reduces the difficulty and time cost of maintenance work, and also reduces the risk of equipment damage and failure caused by improper maintenance.

[0039] The above are only partial or preferred embodiments of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. All equivalent structural changes made using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
