Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, and in particular to a cable fixing device for a 2.0MW doubly fed wind turbine generator set. Background Technology

[0002] 2.0MW doubly fed wind turbine generators are usually erected in open outdoor environments and are subjected to harsh weather conditions such as strong winds, rainstorms, and sandstorms for a long time. During operation, the rotation of the turbine blades and the operation of mechanical components will generate continuous vibrations. In addition, factors such as day-night temperature differences and seasonal temperature changes will place extremely high demands on the fixing of cables. As a key component for power transmission, the stability of the cable is directly related to the normal operation and power generation efficiency of the wind turbine generator.

[0003] However, existing cable fixing devices are insufficient to meet the requirements of the above-mentioned complex working conditions. Some fixing devices have poor vibration damping effect, and long-term vibration can easily lead to wear of the cable sheath or even breakage of the internal core, affecting the stability of power transmission. Some devices cannot adapt to the fixing requirements of different specifications of cables and have poor versatility. Some fixing devices have complex structures, making installation and maintenance difficult and increasing the cost of use and labor. Utility Model Content

[0004] The purpose of this utility model is to provide a cable fixing device for a 2.0MW doubly fed wind turbine generator set, which solves the problems mentioned in the background art, such as poor shock absorption, insufficient versatility, and difficulty in installation and maintenance of existing cable fixing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable fixing device for a 2.0MW doubly-fed wind turbine generator set, comprising a base, two rows of shock absorbers fixedly mounted on the top of the base, a mounting plate fixedly mounted on the top of the two rows of shock absorbers, a first positioning half-ring fixedly mounted on the top of the mounting plate, a first silicone pad fixedly mounted on the inner side of the first positioning half-ring, a telescopic adjusting rod fixedly mounted on the top of the mounting plate, an adjusting pin movably mounted on the telescopic adjusting rod, a positioning top plate fixedly mounted on the top of the positioning top plate, a limit ring fixedly mounted on the top of the limit ring, a threaded rod movably mounted on the inner side of the limit ring, and an adjusting handle fixedly mounted on the top of the threaded rod.

[0006] The threaded rod has a mating piece movably disposed below it, and a second positioning half-ring is fixedly disposed below the mating piece. A second silicone pad is fixedly disposed below the inner side of the second positioning half-ring.

[0007] The inner side of the limiting ring is provided with a thread corresponding to the threaded rod. The lower surface of the threaded rod is rotatably connected to the upper surface of the mating piece. The first positioning half ring and the second positioning half ring can form a complete ring. By rotating the adjustment handle, the threaded rod is driven to rotate within the limiting ring, thereby causing the second positioning half ring to move up and down, so as to achieve the fastening and fixing of cables of different diameters.

[0008] The telescopic adjusting rod has an adjustment hole fixedly provided on its outer side. The telescopic adjusting rod consists of an inner rod and an outer rod that are nested together. The adjusting pin passes through multiple adjustment holes corresponding to the outer rod and the inner rod in sequence to adjust the length of the telescopic adjusting rod. This allows the height of the fixing device to be flexibly adjusted according to the actual installation space and cable routing.

[0009] The dampers are arranged in a matrix, with the top of each damper fixed to the bottom of the mounting plate by bolts, and the bottom of each damper fixed to the top of the base by bolts. The matrix-distributed dampers can absorb the vibrations generated during the operation of the wind turbine generator in all directions, effectively protecting the cables.

[0010] The first and second silicone pads are both provided with anti-slip textures on their surfaces. These textures increase the friction between the pads and the cable, preventing the cable from sliding within the fixing device. At the same time, the silicone pads have good flexibility, which can prevent damage to the cable sheath.

[0011] This utility model discloses a cable fixing device for a 2.0MW doubly fed wind turbine generator set. It achieves efficient vibration reduction through a shock absorber, reducing vibration damage to the cable. The adjustable telescopic adjustment rod and the liftable second positioning half ring improve the device's adaptability to cables of different specifications. The first and second silicone pads, together with the anti-slip texture, not only securely fix the cable but also protect the cable sheath. The overall structure is simple and easy to install and maintain. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a cable fixing device for a 2.0MW doubly fed wind turbine generator set, including a base 1, two rows of shock absorbers 2 fixedly installed above the base 1, a mounting plate 3 fixedly installed above the two rows of shock absorbers 2, a first positioning half ring 4 fixedly installed above the mounting plate 3, a first silicone soft pad 5 fixedly installed on the inner side of the first positioning half ring 4, a telescopic adjustment rod 6 fixedly installed above the mounting plate 3, an adjustment pin 7 movably installed on the telescopic adjustment rod 6, a positioning top plate 8 fixedly installed above the telescopic adjustment rod 6, a limit ring 9 fixedly installed above the positioning top plate 8, a threaded rod 10 movably installed on the inner side of the limit ring 9, and an adjustment handle 11 fixedly installed above the threaded rod 10.

[0020] A mating piece 12 is movably disposed below the threaded rod 10, and a second positioning half-ring 13 is fixedly disposed below the mating piece 12. A second silicone pad 14 is fixedly disposed on the inner side of the second positioning half-ring 13. The inner side of the limiting ring 9 is provided with a thread corresponding to the threaded rod 10. The lower surface of the threaded rod 10 is rotatably connected to the upper surface of the mating piece 12. The first positioning half-ring 4 and the second positioning half-ring 13 can form a complete ring. First, according to the cable installation height, direction and actual installation space, the length of the telescopic adjusting rod 6 is flexibly adjusted by inserting the adjusting pin 7 into different adjusting holes 15 of the telescopic adjusting rod 6, and the mounting plate 3 and the first positioning half-ring 4 are precisely adjusted to the appropriate position. Then, the cable is placed steadily on the first silicone pad 5 of the first positioning half-ring 4. By rotating the adjusting handle 11, the threaded rod 10 is driven to rotate within the limiting ring 9, so that the second positioning half-ring 13 descends steadily until the second silicone pad 14 of the second positioning half-ring 13 is tightly attached to the surface of the cable, thus completing the initial fixation of the cable.

[0021] An adjustment hole 15 is fixedly provided on the outer side of the telescopic adjustment rod 6. The telescopic adjustment rod 6 consists of an inner rod and an outer rod that are nested together. The adjustment pin 7 passes through the multiple adjustment holes 15 corresponding to the outer rod and the inner rod in sequence to adjust the length of the telescopic adjustment rod 6. The shock absorbers 2 are distributed in a matrix. The top of the shock absorber 2 is fixedly connected to the bottom of the mounting plate 3 by bolts, and the bottom of the shock absorber 2 is fixedly connected to the top of the base 1 by bolts. The surfaces of the first silicone pad 5 and the second silicone pad 14 are provided with anti-slip textures 16. When the wind turbine generator is running normally, the matrix-distributed shock absorbers 2 will absorb the vibration generated by the operation of the equipment in all directions, effectively reducing the vibration transmitted to the cable. The anti-slip textures on the surfaces of the first silicone pad 5 and the second silicone pad 14 can increase the friction between the cable and the cable, preventing the cable from sliding in the fixing device due to wind, vibration and other factors. At the same time, the flexibility of the silicone pad can avoid wear on the cable sheath, thus ensuring the stability and safety of the cable fixing under complex and changing working conditions.

[0022] Working principle: When installing the cable, firstly, based on the cable installation height, route, and actual installation space, adjust the length of the telescopic adjusting rod 6 by inserting the adjusting pin 7 into different adjusting holes 15, precisely adjusting the mounting plate 3 and the first positioning half-ring 4 to the appropriate position. Then, place the cable stably on the first silicone pad 5 of the first positioning half-ring 4. By rotating the adjusting handle 11, the threaded rod 10 rotates within the limiting ring 9, causing the second positioning half-ring 13 to descend smoothly until the second silicone pad 14 of the second positioning half-ring 13 is aligned with the cable. The cable surface is tightly adhered, completing the initial fixation of the cable. During normal operation of the wind turbine generator set, the matrix-distributed shock absorbers 2 will absorb the vibration generated by the equipment operation from all directions, effectively reducing the vibration transmission to the cable. The anti-slip texture on the surface of the first silicone pad 5 and the second silicone pad 14 can increase the friction between the pad and the cable, preventing the cable from sliding in the fixing device due to wind, vibration and other factors. At the same time, the flexibility of the silicone pad can avoid wear on the cable sheath, thus continuously ensuring the stability and safety of the cable fixation under complex and changing working conditions.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
