[0002] The dampers of wind turbines in wind farms are usually used to reduce the vibration and noise generated by wind turbines during operation and improve their stability and safety. The dampers can slow down the speed of mechanical vibration by consuming part of the energy, thereby reducing the vibration amplitude and noise level. In wind turbine design, the selection of dampers plays a vital role in ensuring the long-term stable operation and extending the life of the wind turbine.

Multiple sealed damping liquid tanks are stacked in each row. The wind turbine will vibrate during operation, and the damping liquid tank in the existing wind turbine damper is fixed by a tightening rope, which is prone to instability and displacement. There is a risk of the tank falling, causing the wind turbine damper to fail. At the same time, if the damping liquid in the tank leaks, it will cause the damping tank to fail if it is not discovered in time for emergency repairs, resulting in a mismatch between the damping frequency and the actual frequency, and a risk of tower collapse.

[0031] The wind turbine tower damper is a device used to reduce tower vibration. It is usually installed on the internal platform of the tower to reduce the amplitude and frequency of the tower by consuming vibration energy, thereby improving the operating stability and reliability of the wind turbine.

[0032] The working principle of the tower damper is to use the energy dissipation characteristics of the damping material to absorb the vibration energy of the tower. The liquid damper consumes the vibration energy through the flow and friction of the liquid, and has high damping efficiency and reliability.

[0033] By arranging damping liquid tanks, the resistance to vibrations in different directions can be enhanced, thereby improving the stability and reliability of wind turbines. Each damping liquid tank usually contains a certain amount of damping liquid, and the characteristics of the liquid and the structure of the tank will affect the damping effect. The synergistic effect of multiple tanks can more effectively absorb and dissipate vibration energy and reduce the amplitude and vibration frequency of the tower.

[0034] The damping liquid tanks are stored on the internal platform of the wind turbine tower and arranged in a circular array, with multiple sealed damping liquid tanks stacked in each column. The fan will vibrate during operation, and the damping liquid tanks in the existing fan damper are fixed by tightening ropes, which are prone to being unreliable and causing displacement. There is a risk of the tank falling over, causing the fan damper to fail. At the same time, if the damping liquid in the tank leaks, it will also cause the damping liquid tank to fail, causing the damping frequency to not match the actual frequency, and there is a risk of tower collapse.

[0035] Therefore, the inventor proposes a wind turbine tower damper protection device to solve the problems of unstable installation and leakage of the existing damping liquid box.

[0036] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0037] Figure 1 A schematic diagram of the structure of a fixing frame in a wind turbine tower damper protection device provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of an alarm component in a wind turbine tower damper protection device provided in an embodiment of the present application; Figure 3 A diagram showing the use status of a fixing frame in a wind turbine tower damper protection device provided in an embodiment of the present application; Figure 4 This is a schematic diagram of the installation of the damping liquid box in the tower in the embodiment of the present application.

[0038] Reference Figures 1 to 4 As shown, a wind turbine tower damper protection device provided in an embodiment of the present application includes: a fixing frame 1 and an alarm component; the alarm component includes a detection cable 2, an alarm controller 3, a terminal and an alarm 6.

[0039] Specifically, the fixing frame 1 is a frame structure made of metal material, which is sleeved on the outside of each row of damping liquid tanks 7 to fix the damping liquid tanks 7 so that they can be stably stacked on the platform 13 in the tower 12 of the wind turbine.

[0040] The fixing frame 1 is arranged outside the damping fluid tank 7 , and the fixing frame 1 is fixedly connected to the tower 12 .

[0041] Specifically, by fixing the fixing frame 1 and the tower 12 to form a stable structure, the damping liquid tank 7 inside the fixing frame 1 is constrained to prevent the stacked damping liquid tanks 7 from tilting, thereby increasing the stability and reliability of the wind turbine tower damper, improving its damping effect on vibration, and thus ensuring the safe operation of the wind turbine.

[0042] The detection cable 2 is arranged at the bottom of the damping liquid tank 7 .

[0043] Specifically, the detection cable 2 is used to monitor whether the damping liquid box 7 leaks. By arranging the detection cable 2 at the bottom of the box, once the box leaks, the liquid will contact the detection cable 2 to form a loop and generate an electrical signal.

[0044] The detection cable 2, terminal and alarm 6 are respectively connected to the alarm controller 3; when the damping liquid tank 7 leaks, the detection cable 2 contacts the liquid to form a loop, generating a loop signal to the alarm controller 3; after receiving the loop signal, the alarm controller 3 generates an alarm signal and sends the alarm signal to the terminal and alarm 6.

[0045] Specifically, when the damping liquid tank 7 leaks, the liquid contacts the detection cable 2; the detection cable 2 forms an electrical circuit by contacting the liquid; the circuit generates a loop signal and sends the signal to the alarm controller 3; after receiving the loop signal, the alarm controller 3 generates an alarm signal; the alarm signal is sent to the terminal and the alarm 6 to remind relevant personnel to take corresponding measures to perform maintenance in time to prevent the damping liquid tank 7 from failing due to leakage, causing the damping frequency to not match the actual frequency.

[0046] The embodiment of the present application provides a wind turbine tower damper protection device, which constrains the damping liquid tank 7 inside the fixing frame 1 by setting a fixing frame 1 to prevent the stacked damping liquid tanks 7 from tilting, thereby increasing the stability and reliability of the wind turbine tower damper; and sets an alarm component to promptly issue an alarm when leakage is detected, thereby reminding relevant personnel to take corresponding measures to perform maintenance in a timely manner, thereby preventing the damping liquid tank 7 from failing due to leakage, causing the damping frequency to not match the actual frequency, and reducing the possibility of tower 12 collapse due to damping failure.

[0047] In some embodiments, the wind turbine tower damper protection device further includes an anti-wear pad, which is disposed between the fixing frame 1 and the damping liquid tank 7 .

[0048] Specifically, by providing the anti-wear pad, the friction between the fixing frame 1 and the damping liquid tank 7 can be reduced, thereby reducing the possibility of wear and damage to the damping liquid tank 7, and further improving the stability and reliability of the damping liquid tank 7. At the same time, the anti-wear pad can also play a buffering role, reducing the vibration and noise between the fixing frame 1 and the damping liquid tank 7.

[0049] In some embodiments, the anti-wear pad is made of rubber.

[0050] Specifically, rubber has good wear resistance and a long service life; rubber also has good buffering performance, which can reduce the damage to the damping liquid box 7 caused by vibration and impact, protect the damping liquid box 7, and avoid leakage of the damping liquid due to impact.

[0051] In some embodiments, the wind turbine tower damper protection device further includes a liquid level gauge 8 , which is fixed to the outer wall of the damping liquid tank 7 .

[0052] Specifically, fixing the liquid level gauge 8 to the outer wall of the damping liquid tank 7 allows operation and maintenance personnel to easily observe changes in the liquid level in the damping liquid tank 7, promptly discover abnormal liquid level conditions, and take corresponding measures to ensure the normal operation of the damper; at the same time, fixing the liquid level gauge 8 to the outer wall of the damping liquid tank 7 facilitates maintenance, inspection and adjustment of the liquid level gauge 8.

[0053] The liquid level gauge 8 can use a float level gauge, a volumetric level gauge or a pressure level gauge according to actual conditions and needs. Since the damping liquid tank 7 is a closed container, the float level gauge can be used to indicate the liquid level height through the floating and sinking movement of the float, which is simple and easy to use; the volumetric level gauge measures the liquid level height by the change in the volume of the damping liquid tank 7, and has high accuracy and stability; the pressure level gauge measures the liquid level height according to the influence of the liquid in the damping liquid tank 7 on the static pressure, and can be better applied to the harsher wind farm environment.

[0054] In some embodiments, the above-mentioned terminal is a mobile terminal 4 and / or a computer terminal 5 .

[0055] Specifically, by sending the alarm signal to different terminals, it can be ensured that relevant personnel can receive the alarm signal in time and take corresponding measures to reduce risks and losses. For example, the holder of the mobile terminal 4 is the responsible operation and maintenance staff. After receiving the alarm signal, he can rush to the site for maintenance in time to reduce the loss caused by the leakage and the potential safety hazards; and after receiving the alarm signal, the computer terminal 5 can not only allow the user of the computer terminal 5 to find the alarm signal in time and notify the relevant personnel to handle it, but also collect and organize the alarm signal for the convenience of later operation and maintenance personnel to view.

[0056] In some embodiments, the wind turbine tower damper protection device further includes a communication module 9 , and the alarm controller 3 sends the alarm signal to the terminal through the communication module 9 .

[0057] Specifically, the communication module 9 can accurately and efficiently send the alarm signal to the terminal, ensure timely response, reduce errors and interference in signal transmission, reduce the demand for physical cables, and reduce installation and maintenance costs.

[0058] In some embodiments, the communication module 9 is a wireless communication module 9 .

[0059] Specifically, compared with cable transmission, the wireless communication module 9 is not limited by cable length and layout when transmitting signals, and can transmit signals over a wider range and with a faster response speed. It is easy to add or remove terminal devices and has better scalability. It does not require complicated cable wiring, saving installation time and cost. It reduces the possibility of cable failure and reduces the difficulty of maintenance work.

[0060] In some embodiments, the alarm 6 is an audible and visual alarm 6 .

[0061] Specifically, the sound and light alarm 6 can emit sound and light signals at the same time. Through the dual stimulation of sound and light, it is easier to attract the attention of the operation and maintenance personnel so that they can take countermeasures in time.

[0062] In some embodiments, the above-mentioned wind turbine tower damper protection device also includes multiple groups of reinforcement components, the reinforcement components include magnets 10 and reinforcement ropes 11, the magnets 10 are adsorbed and fixed to the tower 12, one end of the reinforcement rope 11 is fixed to the magnet 10, and the other end is fixed to the fixed frame 1.

[0063] Specifically, each group of reinforcement components can select a suitable position to reinforce the fixing frame 1 according to the actual situation. When the reinforcement rope 11 is fixed to the fixing frame 1, it can be convenient to bundle the reinforcement rope 11 by punching holes in the fixing frame 1. The magnet 10 has a strong adsorption force and can be firmly fixed on the surface of the tower 12 and the platform 13, and the reinforcement rope 11 can provide additional support and stability to enhance the overall fixing performance.

[0064] The magnet 10 and the reinforcing rope 11 are easy to operate and install. First, the magnet 10 is adsorbed and fixed on the tower 12, and then connected to the fixing frame 1 through the reinforcing rope 11; the magnet 10 and the reinforcing rope 11 can be reused without affecting the fixing frame 1, and are convenient to disassemble and reinstall.

[0065] The reinforcement rope 11 can be made of nylon rope. Nylon rope has excellent tensile strength. Compared with other rope materials of the same size, nylon rope has a higher carrying capacity and is suitable for occasions with greater tension. The surface of nylon rope is smooth and wear-resistant. It is not easily worn and damaged, and can maintain a longer service life, making it suitable for wind farm environments.

[0066] Nylon rope is easy to tie and overlap, is strong and firm, and not easy to loosen, making it convenient for users to perform binding and fixing operations. At the same time, it has strong corrosion resistance and is not easily affected by the external environment and deteriorated or corroded.

[0067] In some embodiments, the magnet 10 is a neodymium iron boron magnet 10 .

[0068] Specifically, the NdFeB magnet 10 has strong magnetism and can be firmly adsorbed to the tower 12 , so that the fixing frame 1 and the tower 12 are adsorbed and fixed by the reinforcing rope 11 , thereby increasing the stability of the fixing frame 1 .

[0069] At the same time, the NdFeB magnet 10 also has good corrosion resistance and stability, and has a long service life.

[0070] Those skilled in the art will easily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.
