Description

Technical Field

[0001] This utility model relates to the field of conductive rail reinforcement technology, specifically a device for reinforcing and stabilizing conductive rails of wind turbine generators. Background Technology

[0002] Wind turbines are crucial devices for converting wind energy into electricity and are widely used in the renewable energy sector. With increasing global demand for clean energy, wind turbine technology continues to advance, and rated power output continues to rise, resulting in higher power generation efficiency and greater environmental benefits. However, the conductor rail, a key component of wind turbines, also increases in size and weight with the increase in turbine power. During long-term operation, the conductor rail may experience displacement, deformation, and other safety hazards. These problems not only affect the stability of the connection between the conductor rail and the tower but may also lead to a decrease in the overall operational safety of the turbine.

[0003] Patent CN220566181U discloses a wind turbine conductor rail reinforcement device, including a clamp assembly and a suspension adjustment assembly. By adding a suspension adjustment assembly between the conductor rail and the tower, a tensile force is applied to the conductor rail, distributing the pressure at the connection between the conductor rail and the tower. This prevents deformation and damage to the original castings at the connection between the conductor rail and the tower, which could lead to conductor rail sinking. This improves the stability and reliability of the connection between the conductor rail and the tower, ensuring the normal operation of the conductor rail. By setting the suspension adjustment assembly at an angle to the outer wall of the tower, the tensile force exerted by the suspension adjustment assembly on the conductor rail is directed towards the interior of the tower. That is, the suspension adjustment assembly provides not only a vertical upward tensile force on the conductor rail but also a horizontal tensile force towards the interior of the tower, thereby reducing the tendency of the conductor rail to overturn and preventing displacement. This further improves the stability of the conductor rail fixation and provides good anti-displacement effect.

[0004] While the existing technologies described above can provide effective tension to the conductive rail and ensure its stability, they are prone to causing excessive tension on one side when adjusting the two symmetrically arranged suspension adjustment components, leading to the conductive rail deflecting to one side. This not only inconveniences installation and adjustment but may also affect the stability of the conductive rail during use. Therefore, we propose a wind turbine conductive rail reinforcement and stabilization device to address the shortcomings of existing technologies and improve the stability and safety of the conductive rail. Utility Model Content

[0005] The purpose of this invention is to provide a device for reinforcing and stabilizing the conductive rail of a wind turbine generator set, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind turbine conductor rail reinforcement and stabilization device includes a tower and a conductor rail, as well as a connecting assembly connected to the outside of the conductor rail for fixing the conductor rail and transmitting tension.

The top of the first rectangular plate is provided with two first fixing rods arranged symmetrically front and back to transmit tension to the top plate. The top of each of the two first fixing rods is provided with a first U-shaped connecting block to connect the top plate and the adjustment assembly. The bottom of the top plate and near the front and back ends are provided with first connecting protrusions. The first U-shaped connecting blocks are detachably connected to the first connecting protrusions by first clamping bolts and first clamping nuts. After the connection assembly is tightened, the first clamping bolts and first clamping nuts can be locked to fix the relative position of the adjustment assembly and the top plate, thereby ensuring that the conductive rail is effectively tightened.

The top of the second rectangular plate is rotatably connected to a round tube, and the tension is adjusted by rotation.

[0011] Preferably, the top plate has two side plates arranged symmetrically at the bottom and near the center. The opposite sides of the two side plates are respectively attached to the front and rear sides of the rectangular block to enhance the connection stability between the top plate and the rectangular block.

[0013] Preferably, the side of the first U-shaped connecting block is provided with a mounting hole b for the first clamping bolt to pass through, and the side of the first connecting protrusion is provided with a mating hole a for the first clamping bolt to pass through, thus providing a passage for the first clamping bolt to pass through.

[0014] Preferably, the outer wall of the round rod is in contact with the inner wall of the round tube, and at least two locking bolts are threadedly connected to the outer wall of the round tube near the top.

[0015] Preferably, the side of the second U-shaped connecting block is provided with a mounting hole c for the second clamping bolt to pass through, and the side of the second connecting protrusion is provided with a mating hole c for the second clamping bolt to pass through, thus providing a passage for the second clamping bolt to pass through.

[0016] Preferably, the inner wall of the U-shaped retaining plate is bonded with a rubber liner, and the left side of the locking plate is bonded with a rubber pad. The inner wall of the rubber liner and the left side of the rubber pad are both tightly fitted to the outer wall of the conductive rail, protecting the surface of the conductive rail and improving the stability of the connection between the connecting component and the conductive rail.

[0017] Preferably, the U-shaped clamping plate has mounting wing plates on the right edge of both the front and rear sides. The mounting wing plates have two symmetrically arranged docking holes b on the right side. The locking plate has threaded posts on the left side near the four corners. The threaded posts pass through the docking holes b and are threaded with locking nuts to ensure that the U-shaped clamping plate and the locking plate are firmly clamped on the outside of the conductive rail.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The wind turbine's conductive rail reinforcement and stabilization device, through the design of the threaded rod and round tube of the adjustment component, realizes single-point rotation adjustment of the tension on both sides, completely avoiding the deflection of the conductive rail caused by the adjustment deviation of the traditional symmetrical suspension component, ensuring the balance of the force on the conductive rail, and significantly improving the fixation stability.

[0020] 2. The wind turbine's conductive rail reinforcement and stabilization device adopts a combination of U-shaped clamping plate and locking plate clamping structure, combined with rubber lining and rubber pad buffer protection, which effectively reduces mechanical wear between the conductive rail and the reinforcement device and prevents the conductive rail from shifting or deforming during long-term operation.
