Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wind turbine technology, and in particular relates to a wind turbine conductive rail reinforcement device. Background Technology
[0002] The conductor rail of a wind turbine is a crucial component for power transmission and also one of the most valuable parts of the unit. Analysis of the current operating status of the units revealed that the initial design of the conductor rail support structure did not consider the weight of the conductor rail itself, the strength of the fixing components, and vibrations during turbine operation. This has led to problems such as fatigue of connectors and bolt loosening after prolonged operation, affecting the normal operation of the units.
[0003] Currently, wind turbine conductor rails are typically installed on the exterior of the wind turbine tower. This installation method requires that the conductor rails not rub against or collide with the generator blades or other components to ensure safe and stable operation. While commercially available conductor rail reinforcement devices can improve the stability of the conductor rail support and prevent it from sagging, after long-term use, the lack of a plug-in limiting mechanism still leads to safety hazards such as conductor rail displacement, thus affecting the overall stability and safety of the unit. Therefore, based on the above problems, we designed a wind turbine conductor rail reinforcement device. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a wind turbine conductive rail reinforcement device, which solves the technical problems of easy displacement and poor stability of the conductive rail during the installation and use of existing wind turbine conductive rails.
[0005] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a wind turbine conductor rail reinforcement device is provided, comprising a conductor rail disposed on the side of the wind turbine tower:

[0008] The reinforcement mechanism includes a clamping ring fitted onto the wind turbine tower, a U-shaped bracket clamped onto the conductive rail, and side reinforcement triangular brackets located on both sides of the U-shaped bracket and connected at one end to the two sides of the clamping ring.
[0009] A further improvement is that a set of grooves for mounting with studs are provided at the edge of the clamp ring, and each stud is provided with a nut.
[0010] A further improvement is that the U-shaped bracket is divided into a mounting rod and a fitting rod rotatably disposed in the ports at both ends of the mounting rod. The conductive rail is recessed on both sides, and the inner wall surface of each fitting rod matches the recessed surfaces on both sides of the conductive rail. A positioning pin is vertically disposed in the middle of the inner wall surface of the mounting rod.

Each half clamp has a washer on its inner wall surface and a fixing bolt at its end. The clamp ring is installed on the wind turbine tower by the fixing bolt.
[0012] A further improvement is that the right-angle ends of the two side-reinforced triangular frames are connected by fixing bolts and each half clamp, and the other two ends are connected by fixing bolts and each mounting rod and the wind turbine tower, respectively.
[0013] A further improvement is that each end of the mounting rod and the end of the fitting rod are provided with positioning bolts, and the conductive rail is provided with positioning holes at the positions where each positioning bolt is located.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figures 1 to 4 As shown, a wind turbine conductive rail reinforcement device includes a conductive rail 2, which is disposed on the side of the wind turbine tower 1.
[0024] A fixing collar 11 is fitted onto the outside of the wind turbine tower 1, and several studs 101 are provided on the surface of the fixing collar 11;
[0025] The reinforcement mechanism 3 includes a clamp ring 31 fitted on the wind turbine tower 1, a U-shaped bracket 32 clamped on the conductive rail 2, and a side reinforcement triangle 33 set on both sides of the U-shaped bracket 32 and connected at the other end to both sides of the clamp ring 31.
[0026] Specifically, a set of slots 301 for mounting with studs 101 are provided at the edge of the clamp ring 31, and a nut 302 is provided on each stud 101;
[0027] Specifically, the U-shaped bracket 32 consists of an installation rod 321 and fitting rods 322 rotatably disposed within the two ends of the installation rod 321. The conductive rail 2 is recessed on both sides. The inner wall surface of each fitting rod 322 matches the concave surfaces on both sides of the conductive rail 2. A positioning pin 323 is vertically disposed in the middle of the inner wall surface of the installation rod 321. Positioning bolts 324 are disposed at both ends of each installation rod 321 and both ends of the fitting rod 322. Positioning holes are disposed on the conductive rail 2 at the positions of each positioning bolt 324. By inserting the positioning pin 323 on the inner wall surface of the installation rod 321 into the positioning slot on the conductive rail 2, the inner wall surface of each fitting rod 322 matches the concave surfaces on both sides of the conductive rail 2. In this way, the U-shaped bracket 32 is conveniently installed on the conductive rail 2 using the positioning bolts 324.
[0028] Specifically, the clamp ring 31 is divided into a pair of half clamps 311, with grooves 301 respectively set on each half clamp 311. Each half clamp 311 has a washer 312 on its inner wall surface and a fixing bolt 313 at its end. The clamp ring 31 is installed on the wind turbine tower 1 by fixing bolts 313. By fitting the half clamp 311 onto the wind turbine tower 1, the grooves 301 on the bottom surface of the clamp ring 31 fit onto each stud 101, and then tightening the nut 302 to secure the clamp ring 31, the two clamp rings 31 are finally connected at both ends by fixing bolts 313, thereby installing the entire clamp ring 31 on the wind turbine tower 1.
[0029] Specifically, the right-angle ends of the two side-reinforcing triangular frames 33 are connected by fixing bolts 313 and each half clamp 311, and the other two ends are connected by fixing bolts 313 and each mounting rod 321 to the wind turbine tower 1, respectively. By connecting the right-angle ends of the two side-reinforcing triangular frames 33 with fixing bolts 313 and each half clamp 311, and connecting the other two ends with fixing bolts 313 and each mounting rod 321 to the wind turbine tower 1, a stable reinforcement and limiting mechanism is formed. This design reinforces and limits the connection between the wind turbine tower 1 and the conductive rail 2, which can enhance the structural stability between the wind turbine tower 1 and the conductive rail 2, effectively prevent the conductive rail 2 from shifting, thereby greatly improving the stability of the entire wind turbine during operation and ensuring the safety and reliability of the equipment.
[0030] like Figures 1 to 4 As shown, in this embodiment, the size of the reinforcement device is selected according to the actual needs of the site, and the working principle of the conductive rail 2 and the wind turbine has been disclosed. It should be noted that this application only addresses the shortcomings of existing wind turbine conductive rails, such as easy displacement and poor stability, and does not involve other aspects.
[0031] The application document describes several reinforcement mechanisms 3, which are equidistantly installed on the conductive rail 2 and the wind turbine tower 1 for segmented reinforcement and support. This embodiment takes one segment as an example. The working principle of this wind turbine conductive rail reinforcement device is described below:
[0032] When using this new type of equipment, the assembler selects a washer 312 of appropriate size and installs it inside the two half clamps 311. Then, the half clamps 311 are put on the wind turbine tower 1, so that the groove 301 on the bottom of the clamp ring 31 fits on each stud 101. Then, the nut 302 is tightened to secure the clamp ring 31. Finally, the two ends of the two clamp rings 31 are connected by fixing bolts 313, so that the entire clamp ring 31 is installed on the wind turbine tower 1.
[0033] Then, the positioning pins 323 on the inner wall of the mounting rod 321 are inserted into the positioning slots on the conductive rail 2, so that the inner wall of each fitting rod 322 matches the concave surfaces on both sides of the conductive rail 2. In this way, the U-shaped bracket 32 is installed on the conductive rail 2 using the positioning bolts 324. Finally, the right-angle ends of the two side-reinforcing triangular brackets 33 are connected to each half clamp 311 by fixing bolts 313, and the other two ends are connected to each mounting rod 321 and the wind turbine tower 1 by fixing bolts 313 respectively, forming a stable reinforcement and limiting mechanism. This design reinforces and limits the connection between the wind turbine tower 1 and the conductive rail 2, which can enhance the structural stability between the wind turbine tower 1 and the conductive rail 2, effectively prevent the conductive rail 2 from shifting, thereby greatly improving the stability of the entire wind turbine during operation and ensuring the safety and reliability of the equipment.
[0034] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
