And wind energy bus as the medium of power transmission, is an essential component of wind turbine, its main role is to transmit the power generated by wind turbine to the grid.

[0004] In the actual use of wind turbine, due to the instability and randomness of wind, the pipe bus will vibrate itself under the action of wind, and also vibrate with the tower. Frequent vibration of bus, especially large amplitude vibration, will have a great impact on the connection part of bus, easy to cause wear, loose and even fall off of bus connection. Once the bus connection appears these problems, will lead to power transmission failure, seriously affect the normal operation of wind turbine, and even may cause safety accidents.

[0005] At present, most of the busbar support support in the market lacks effective buffer design, and cannot effectively buffer and absorb the vibration of bus. When the bus vibrates, due to the lack of buffer measures, the vibration energy of the bus cannot be released, and can only be consumed by friction and collision of bus connection, thereby accelerating the wear and damage of bus connection. Therefore, the existing busbar support support cannot meet the requirements of wind turbine on bus stability and reliability, and needs to be improved.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] The present utility model provides a multi-busbar support bracket with elastic buffering ability.

[0025] In this embodiment, referring to Figures 1-3 , the multi-busbar support bracket with elastic buffering ability includes an upper bracket 1 and a lower bracket 2. Three arc-shaped grooves are provided on both the upper bracket 1 and the lower bracket 2. Three busbar holes 3 distributed in a "pin" shape are formed between the arc-shaped grooves on the upper bracket and the lower bracket. It also includes an elastic buffering component. The elastic buffering component includes a fixed base 4, a fixed cross plate 5 connected to the lower bracket, connecting columns 6 spaced on the fixed cross plate 5, a hexagonal block 7 fixed on the top of the connecting column 6, limiting rods 8 spaced on the side of the hexagonal block 7, and buffer springs 9 spaced on the side of the hexagonal block. A hexagonal hole 10 for the hexagonal block to extend into is provided on the fixed base. A first buffer gap 11 is left between the hexagonal holes 10. One end of the buffer spring 9 away from the hexagonal block is fixedly connected to the inner wall of the hexagonal hole. The end of the limiting rod away from the hexagonal block is movably配合 with a limiting hole on the inner wall of the hexagonal hole, and a second buffer gap 12 is left between the limiting hole and the limiting rod.

[0026] In the above technical solution, by setting the elastic buffering component, the elastic buffering ability of the bracket is significantly improved. When the busbar is subjected to external forces such as wind force and mechanical vibration, the elastic buffering component can effectively absorb and buffer these external forces, reduce the direct impact of the external forces on the busbar and the bracket, reduce the risk of wear and damage between the busbar and the bracket, ensure the stable operation of the busbar, and improve the safety and reliability of the wind power generation system.

[0027] Working principle of the elastic buffering component: When the busbar is subjected to external forces such as wind force and mechanical vibration, it will cause a certain displacement and vibration of the upper bracket and the lower bracket. At this time, the fixed cross plate connected to the lower bracket will also move accordingly, and then drive the hexagonal block to move in the hexagonal hole of the fixed base through the connecting column.

[0028] The hexagonal block has a certain space for movement in the hexagonal hole when subjected to external force, and the buffer spring fixed to the inner wall of the hexagonal hole is compressed or stretched, thereby absorbing and buffering the external force and converting the energy of the external force into the elastic potential energy of the spring. Meanwhile, the limiting rod moves in the limiting hole under the driving of the hexagonal block, and the limiting rod also has a certain range of movement due to the buffer gap between the limiting hole and the limiting rod. The limiting rod limits the excessive displacement of the hexagonal block, and when the displacement of the hexagonal block reaches a certain degree, the limiting rod contacts the inner wall of the limiting hole to prevent the hexagonal block from moving excessively, so as to ensure that the buffer spring works within a reasonable range and avoid structural instability caused by excessive buffering. When the external force disappears, the buffer spring gradually returns to its original state and releases the stored elastic potential energy, so that the hexagonal block, the limiting rod and other components return to the initial position and are ready for the next buffering. Through such a cycle, the elastic buffer assembly can continuously and effectively provide elastic buffering protection for the busbar.

[0029] Specifically, the limiting rods and the buffer springs are alternately arranged on the six sides of the hexagonal block.

[0030] In this embodiment, the limiting rods and the buffer springs are alternately arranged on the six sides of the hexagonal block, and this arrangement enables the hexagonal block to be effectively buffered and limited in all directions when subjected to external force. The external force can be more evenly dispersed, and local excessive wear or damage caused by uneven force can be avoided, thereby further improving the buffering performance and service life of the elastic buffer assembly and enhancing the adaptability of the busbar support bracket to external force in different directions.

[0031] Specifically, the hexagonal block 7 is fixed to the top of the connecting column 6 by a bolt 13.

[0032] In this embodiment, the hexagonal block is fixed to the top of the connecting column by a bolt, and this connection is simple and reliable, facilitating installation and disassembly. When the elastic buffer assembly needs to be maintained or replaced, the hexagonal block can be conveniently disassembled from the connecting column, thereby improving the convenience of maintenance.

[0033] Specifically, a rubber sleeve 14 is sleeved on the top of the limiting rod.

[0034] In this embodiment, a rubber sleeve is sleeved on the top of the limiting rod, and the rubber sleeve has good elasticity and buffering performance. When the limiting rod contacts the limiting hole, the rubber sleeve can play a buffering role to reduce the rigid collision between the limiting rod and the limiting hole and reduce noise and wear.

[0035] Specifically, the fixed base has mounting plates 15 at both ends, and the mounting plates 15 are provided with waist-shaped mounting holes 16.

[0036] In the embodiment, the two ends of the fixing base are provided with mounting plates 15, and the mounting plates are provided with waist-shaped mounting holes, which increases the flexibility of the mounting of the fixing base. The waist-shaped mounting holes can adjust the mounting position of the fixing base within a certain range, facilitate the adaptation with different mounting structures, and improve the universality and applicability of the support. Meanwhile, the waist-shaped mounting holes can compensate for the errors in the mounting process to some extent, so that the mounting is more convenient and fast.

[0037] Specifically, the gap width of the buffer gap one and the buffer gap two is 0.5-2cm.

[0038] In the embodiment, the gap width of the buffer gap one and the buffer gap two is set to 0.5-2cm, which can not only ensure that the hexagonal block and the limiting rod have enough space to buffer when subjected to external force, but also avoid that the gap is too large to cause poor buffering effect or unstable structure. The appropriate gap width enables the elastic buffering assembly to better play a role in the buffering process, effectively absorbs and disperses external force, and protects the structure safety of the busbar and the support.

[0039] Skilled persons should know that although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to the utility model, and any modification using the utility model idea will be included in the patent protection range.
