Description

Technical Field

[0001] The utility model belongs to the technical field of cable suspension brackets, and particularly relates to a cable suspension bracket for a wind turbine generator set. Background Technique

[0002] A wind turbine generator set generates electricity by wind power. The wind turbine generator is arranged on the wind turbine tower. The electric energy generated by the wind turbine generator needs to be transmitted from the top of the wind turbine tower to the power grid through cables. The cables are arranged in the tower barrel of the wind turbine tower. Due to the high height of the wind turbine tower, the vertical height of the cables in the tower barrel is relatively high, and the number of cables is generally composed of several or several groups.

[0003] In the patent with the application number 202222405554.2, a cable suspension bracket for a wind turbine generator set is disclosed. This cable suspension bracket for a wind turbine generator set drives the lead screw to rotate by rotating the hand wheel, and at the same time drives the adjusting sleeve and the top wire harness seat to move, so that the top wire harness seat moves and fits with the bottom limit seat to clamp and fix the cable, so that the cable will not move easily during use, and it is convenient to limit the wire harness, achieving the advantage of good suspension effect; however, after the existing wind turbine generator is installed, due to the large number of cables and the heavy weight of the cables, it is necessary to suspend the cables to prevent the cables from being pulled due to their own gravity and disengaging from the wind turbine generator set, resulting in power collection loss. Therefore, the requirements for the cable suspension and fixing device are relatively high; currently, mainly metal wire suspension nets are used to suspend the cables. However, due to the large weight of the cables themselves, over time, the metal wire suspension nets will sink into the outer skin of the cables, resulting in damage to the outer skin of the cables, causing power loss of the cables and possibly triggering other safety accidents. For this reason, we propose a cable suspension bracket for a wind turbine generator set. Content of the Utility Model

The plurality of cable bracket assemblies 4 each include a sliding seat 4.1 slidably connected to the two guiding link rods 3. A fixed seat 4.3 is hinged to the bottom of the sliding seat 4.1 through a rotating shaft 4.2. A buffer plate 4.4 is fixedly connected to the bottom of the sliding seat 4.1. A screw rod 4.5 threadedly connected thereto is penetrated through the fixed seat 4.3. The top end of the screw rod 4.5 is rotatably connected to a support plate 4.7 through a bearing 4.6. The bottom end of the screw rod 4.5 is fixedly connected to a rotating block 4.8. A fixing groove 4.9 is provided at the top of the sliding seat 4.1, and a spring 4.10 connected to the sliding seat 4.1 is provided in the fixing groove 4.9. The top end of the spring 4.10 is connected to a limiting block 4.11 cooperating with the limiting plate 2.

[0024] As Figure 1 and Figure 2 shown, a plurality of mounting holes 1.1 are provided on each of the two mounting plates 1 in the present utility model, which facilitates the installation of the whole.

[0025] As Figure 1 , Figure 2 , Figure 4 shown, both of the two guiding link rods 3 in the present utility model penetrate through the sliding seat 4.1, and a guiding through groove 4.12 for the guiding link rod 3 to pass through is provided on the sliding seat 4.1, which facilitates controlling the sliding of the cable bracket assembly 4 on the guiding link rod 3, thereby facilitating the adjustment of the position of the cable bracket assembly 4.

[0026] As Figure 3 shown, a connecting plate one 4.13 is fixedly connected to one side of the sliding seat 4.1 in the present utility model, a connecting plate two 4.14 is fixedly connected to one side of the fixed seat 4.3, and the connecting plate one 4.13 and the connecting plate two 4.14 are connected by a locking bolt 4.15, which facilitates the fixation of the fixed seat 4.3 and the sliding seat 4.1 through the locking bolt 4.15.

[0027] As Figure 4 shown, a threaded groove for the screw rod 4.5 to pass through is provided on the fixed seat 4.3 in the present utility model, and when the screw rod 4.5 rotates, it will slide.

[0028] As Figure 5 shown, the limiting block 4.11 is slidably connected to the sliding seat 4.1 in the present utility model. Sliders 4.16 are fixedly connected to both sides of the limiting block 4.11, and sliding grooves 4.17 for the sliders 4.16 to slide are provided on both sides of the fixing groove 4.9 in the sliding seat 4.1, which improves the sliding stability of the limiting block 4.11 and plays a guiding role in the sliding of the limiting block 4.11.

[0029] As Figure 1 andFigure 2 As shown, in the present utility model, a plurality of limiting grooves 4.18 that cooperate with the limiting blocks 4.11 are provided on the limiting plate 2, and the plurality of limiting grooves 4.18 are evenly distributed on the limiting plate 2. The limiting blocks 4.11 are limited and fixed through the limiting grooves 4.18 on the limiting plate 2, so as to limit the cable bracket assembly 4, so that the cable will not move easily during use.

[0030] Working principle and usage process of the present utility model: When this application is specifically implemented, it is first installed through the installation holes 1.1 on the mounting plate 1. When hanging and fixing the cable, first place the cable between the sliding seat 4.1 and the fixed seat 4.3, and between the support plate 4.7 and the buffer plate 4.4, and then lock and fix the connecting plate one 4.13 and the connecting plate two 4.14 through the locking bolt 4.15, so as to realize the fixation of the fixed seat 4.3 and the sliding seat 4.1. Then rotate the rotating block 4.8 to drive the screw rod 4.5 to rotate. Since the screw rod 4.5 is threadedly connected to the fixed seat 4.3, when the screw rod 4.5 rotates, it will slide upward, thereby driving the support plate 4.7 to move upward to fix the cable, so as to facilitate the limiting process of the cable. At the same time, the limiting block 4.11 can be pressed downward to move it downward into the fixing groove 4.9. At this time, the spring 4.10 is in a compressed state, and at this time, the cable bracket assembly 4 can be controlled to slide on the guiding connecting rod 3 to adjust the position of the cable bracket assembly 4. When adjusted to the appropriate position, the elastic potential energy of the spring 4.10 causes it to return to its original state, so that the limiting block 4.11 moves upward into the limiting groove 4.18. At this time, the limiting groove 4.18 on the limiting plate 2 limits and fixes the limiting block 4.11, so as to limit the cable bracket assembly 4, so that the cable will not move easily during use, and the distance between the cables can be adjusted, thereby improving the practicability of cable hanging.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
