[0002] A fan, also known as a wind turbine or wind generator, is a device that converts the kinetic energy of wind into mechanical energy and then into electrical energy through a generator. A wind turbine typically consists of components such as a wind wheel, a generator, a yaw mechanism, a tower, a speed-limiting safety mechanism, and an energy storage device. The wind wheel rotates under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and then the generator rotates to generate electricity driven by the wind wheel shaft.

[0003] During the operation of a fan, inspections and maintenance are inevitably required. In this process, maintenance personnel need to climb to the top of the tower inside the fan. With the continuous progress of technology, the way for maintenance personnel to climb the tower has changed from climbing manually to climbing with the help of climbing devices and then to climbing the tower completely through the carriage, greatly reducing the burden on workers and improving work efficiency.

[0004] However, with the rotation of the wind turbine blades, the tower barrel inevitably vibrates and sways. During this process, the wire ropes on the carriage inside the tower barrel will vibrate and swing irregularly, making it impossible for the wire ropes to maintain a vertical state. In severe cases, they will contact other support components inside the tower barrel, be worn when the carriage ascends, and even break away from the rope groove or sprocket, posing a great safety risk.

[0028] The present application provides a wire rope fixing device for a fan car to reduce the tremor and swing of the wire rope and reduce the safety risk. The specific implementation process of the present application is described as follows.

[0029] Please refer to Figures 1 to 3 , a wire rope fixing device for a fan car provided by the present application includes:

[0030] A bracket 01 and a fixing member 02, the bracket 01 is connected to the fixing member 02, and the bracket 01 is used to fix the fixing member 02 on the ladder in the tower barrel; the fixing member 02 includes a first fixing plate 03 and a second fixing plate 04 which are detachably connected. One side of the first fixing plate 03 is used to be connected to the bracket 01, and a plurality of first notches 05 are provided on the other side. A plurality of second notches 06 are provided on one side of the second fixing plate 04. The first notches 05 are used to form an accommodating hole in combination with the second notches 06, and the accommodating hole is used to place the wire rope.

[0031] The bracket 01 can be made of high-strength and corrosion-resistant metal materials, such as stainless steel or alloy steel, to ensure that it does not deform or rust during long-term use in a harsh wind farm environment. One end of the bracket 01 is fixedly connected to the fixing member 02, and the other end is fixedly connected to the ladder. In a feasible manner, the end fixedly connected to the ladder can be designed as a U-shaped or L-shaped structure, and the bracket 01 and the ladder can be fixedly connected by bolts.

[0032] The fixing member 02 is composed of a first fixing plate 03 and a second fixing plate 04. Both can be made of metal plates of the same or similar material as the bracket 01 to ensure the strength and durability of the overall structure. The first fixing plate 03 and the second fixing plate 04 can be combined together by bolts, pins or other detachable connection methods.

[0033] The first notch 05 and the second notch 06: The first notch 05 on the first fixing plate 03 and the second notch 06 on the second fixing plate 04 are designed with matching shapes and dimensions so that they can be precisely aligned and form a stable receiving hole when combined. The shape of the formed receiving hole can be circular, oval, or a shape specially made according to the diameter of the wire rope to ensure that the wire rope can be safely fixed in the receiving hole. Moreover, the inner diameter of the receiving hole needs to be slightly larger than the outer diameter of the wire rope, which facilitates the operation of the wire rope. Here, "slightly" means that when the wire rope operates normally without swaying, the wire rope does not contact the receiving hole, but when the wire rope sways, the receiving hole plays a role in restricting the sway of the wire rope. For the aperture of the receiving hole, for example, the aperture of the receiving hole is 5 cm, and the diameter of the cross-section of a single wire rope is 4.5 cm.

[0034] It should be noted that according to the height of the tower barrel, multiple wire rope fixing devices can be arranged on the wire rope to reduce the overall sway degree of the wire rope.

[0035] In an alternative embodiment, a fastener 07 is provided on the first fixing plate 03, and the fastener 07 is used to fixedly connect the first fixing plate 03 and the second fixing plate 04. In this embodiment, common fasteners 07 include bolts, nuts, pins, rivets, etc. The specific selection of the fastener 07 is not limited here and shall be subject to actual feasibility.

[0036] In another alternative embodiment, a circular rib 08 is provided on the first fixing plate 03, and a circular groove 09 is provided on the second fixing plate 04. The circular rib 08 and the circular groove 09 cooperate to fixedly connect the first fixing plate 03 and the second fixing plate 04.

[0037] In this embodiment, a certain number and specifications of circular ribs 08 are provided on the first fixing plate 03. The size, shape, and position of the circular rib 08 correspond and match those of the circular groove 09 on the second fixing plate 04. The circular rib 08 and the first fixing plate 03 are integrally formed. The circular groove 09 is provided on the second fixing plate 04 and corresponds to the circular rib 08 on the first fixing plate 03. The size of the circular groove 09 should be slightly larger than that of the circular rib 08 to allow for a certain assembly gap and tolerance adjustment. The bottom and side walls of the circular groove 09 should be smooth and flat to reduce friction and resistance during assembly. It should be noted that circular ribs 08 and circular grooves 09 can be provided on the first fixing plate 03 at the same time, and the circular ribs 08 and circular grooves 09 need to be arranged at intervals. Similarly, circular ribs 08 and circular grooves 09 are also arranged at intervals on the second fixing plate 04.

[0038] During assembly, first fix the first fixing plate 03 on the ladder through the bracket 01, then place the steel wire rope into the first notch 05, align the circular rib 08 with the circular groove 09 and gently push it in. After complete insertion, the accommodating hole formed by the first notch 05 and the second notch 06 restricts the steel wire rope. The design of the circular rib 08 and the circular groove 09 ensures the accuracy and stability during their connection. Compared with the traditional flat contact fixing method, the design of the circular rib 08 and the groove increases the contact area, thereby improving the connection strength and stability. Moreover, the design of the circular rib 08 and the groove makes the installation and disassembly process of the fixing device more simple and fast.

[0039] In an alternative embodiment, an annular stop strip is provided on the outer wall of the circular rib 08, and two annular limiting strips are provided on the inner wall of the circular groove 09. The annular stop strip can be accommodated between the two annular limiting strips. After the circular rib 08 is pushed into the circular groove 09, the annular stop strip is snapped into the space between the two annular limiting strips.

[0040] In this embodiment, the annular stop strip is provided on the outer wall of the circular rib 08. The main functions of the annular stop strip are positioning and locking. It plays a locking role when the circular rib 08 is pushed into the circular groove 09. The annular stop strip can slide into the circular groove 09 together with the circular rib 08 and just snap into the space between the two annular limiting strips when reaching the predetermined position. Two annular limiting strips are provided on the inner wall of the circular groove 09. The space between the two annular limiting strips is used to accommodate the annular stop strip, and the two limiting strips are used to define the movement track of the annular stop strip to prevent the circular rib 08 from accidentally coming out when subjected to external forces, so as to ensure the stable connection between the first fixing plate 03 and the second fixing plate 04. The size and position of the annular limiting strips need to match the annular stop strip to ensure tight fit and stable locking between the two.

[0041] In an alternative embodiment, a ladder fixing plate 10 is provided at one end of the bracket 01. An arc-shaped adjusting plate 11 is provided on the ladder fixing plate 10.

The bracket 01 has two ends. One end is connected to the first fixing plate 03, and the other end is used to connect to the ladder. A ladder fixing plate 10 is provided at this end. The shape and size of the ladder fixing plate 10 can be designed according to the specific structure and size of the ladder to ensure a tight fit between the two; the connecting piece is the hub connecting the arc-shaped adjusting plate 11 and the ladder fixing plate 10. The connecting piece allows the arc-shaped adjusting plate 11 to rotate around it. The connecting piece can be made of high-strength and corrosion-resistant materials to ensure stable connection performance during long-term use, such as hinges, hinges, etc. The arc-shaped adjusting plate 11 can be adjusted according to the specific structure and size of the ladder, and the rotation angle of the arc-shaped adjusting plate 11 is adjusted to ensure that the arc-shaped adjusting plate 11 and the ladder fixing plate 10 cooperate with each other to clamp the ladder.

[0042] In an alternative embodiment, an arc surface 12 is provided on one side of the ladder fixing plate 10 facing the arc-shaped adjusting plate 11. The arc surface 12 is recessed inward, and a "()" structure is formed between the arc surface 12 and the arc-shaped adjusting plate 11. Thus, when the ladder is circular, the arc surface 12 and the arc-shaped adjusting plate 11 can respectively have a relatively large contact area with the ladder, thereby achieving a firm connection.

[0043] In an alternative embodiment, rubber gaskets are provided on the arc surface 12 and on the arc-shaped adjusting plate. The rubber gaskets are fixedly connected to the arc surface 12 by an adhesion method, and the arc-shaped adjusting plate and the rubber gaskets can also be fixedly connected by an adhesion method. By providing the rubber gaskets, the connection friction between the ladder fixing plate 10 and the ladder can be enhanced, and the connection friction between the arc-shaped adjusting plate and the ladder can also be enhanced, ensuring the stability of the connection.

[0044] In an alternative embodiment, two pins are provided at the other end of the bracket 01. The two pins are respectively connected to the first fixing plate 03 by bolts. Two pins are provided at one end of the bracket 01 connected to the fixing member 02. The two pins are of equal length and have the same structure.

[0045] Optionally, symmetric second notches 06 are provided on both sides of the second fixing plate 04. In an actual scenario, there may be a single row of steel wire ropes, or there may be two rows of steel wire ropes. Therefore, in this embodiment, symmetric second notches 06 are provided on both sides of the second fixing plate 04, so that both sides of the second fixing plate 04 can be cooperatively connected to the first fixing plate 03, thereby achieving the restriction of two rows of steel wire ropes.

[0046] Optionally, the inner walls of the first notch 05 and the second notch are respectively smooth. The smooth inner walls can ensure the smooth running of the steel wire ropes. Further, a liquid with a lubricating effect can be applied to the inner walls of the first notch 05 and the second notch 06.
