[0002] With the increasing global demand for renewable energy, wind power, as a clean and renewable energy source, is becoming increasingly important. Wind turbine towers, as a key component of wind power systems, bear the crucial responsibility of supporting wind turbines, transmitting wind energy, and converting it into electrical energy.

[0003] During operation, wind turbine towers are subjected to enormous wind loads, especially under extreme weather conditions such as sudden increases in wind speed or changes in wind direction. Due to their height, wind turbine towers are prone to vibration and even toppling, have poor wind resistance, and are difficult to drive away birds or prevent them from colliding with the blades of the wind turbine tower.

[0004] Therefore, we have made improvements to this and proposed a wind-load resistant structure for wind power generation towers. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a wind-resistant structure for a wind power tower, including a base 1. A vertical rod 2 is detachably connected to the top of the base 1 via a bolt assembly. A reinforcing mechanism 3 is installed on the vertical rod 2. A main unit 4 is fixedly connected to the bottom of the vertical rod 2. A fan blade 5 is installed at the end of the main unit 4. A wind-resistant damping mechanism 6 is provided inside the vertical rod 2, and a bird-repelling mechanism 7 is provided at the top of the vertical rod 2. The base 1 and the vertical rod 2 facilitate installation and disassembly, and make maintenance and replacement convenient. The composition of the main unit 4 and the fan blade 5 is prior art and will not be described in detail here.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, the reinforcement mechanism 3 further includes a fixing ring 301 fixed to the vertical rod 2. Three mounting heads 302 are evenly fixedly connected to the fixing ring 301. The three mounting heads 302 are respectively connected to a first connector 303 by bolt assemblies. A first steel cable 304 is fixedly connected to the bottom end of the first connector 303. A second connector 305 is fixedly connected to the bottom end of the first steel cable 304. The second connector 305 is connected to a fixing seat 306 by bolt assemblies. The vertical rod 2 can be reinforced by the first steel cable 304 and the fixing seat 306, so that the entire reinforcement mechanism 3 can effectively disperse and resist wind force and enhance the stability of the tower.

[0030] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the wind-resistant damping mechanism 6 further includes a second steel cable 601 fixed to the inner top wall of the vertical rod 2. A lifting ring 602 is fixedly connected to the bottom end of the second steel cable 601. A connecting ring 603 is provided inside the lifting ring 602. A weighted ball 604 is fixedly connected to the bottom end of the connecting ring 603. An annular seat 605 is provided on the outer side of the weighted ball 604. The annular seat 605 is fixedly connected to the inner side wall of the vertical rod 2. Four connecting blocks 606 are evenly fixedly connected inside the annular seat 605. A first connecting head 607 is rotatably connected to each of the four connecting blocks 606. The first connecting head 607 is connected to a second connecting head 609 through a damping rod 608. A spring 6010 is fitted, with its two ends fixedly connected to a first connector 607 and a second connector 609, respectively. A connecting block 6011 is rotatably connected inside the second connector 609, and the connecting block 6011 is fixedly connected to the ball weight 604. When wind force acts on the vertical rod 2, the ball weight 604 will sway due to the wind force. The swaying of the ball weight 604 is transmitted to the connecting block 6011. The damping rod 608 and the spring 6010 buffer the ball weight 604, thereby slowing down the swaying speed of the ball weight 604. This can effectively reduce the impact of wind force on the vertical rod 2, improve the wind resistance of the tower, and also make the ball weight 604 sway stably within a certain range, avoiding excessive swaying that could damage the tower.

[0031] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, the bird deterrent mechanism 7 further includes a mounting plate 701 fixed to the top of the vertical rod 2. A set of strobe lights 702 are uniformly fixedly connected to the lower end surface of the mounting plate 701. A speaker 703 is provided between adjacent strobe lights 702. The speaker 703 is fixedly connected to the mounting plate 701. The strobe lights 702 can emit strong flashes, which will visually stimulate and disturb the birds, making them dare not approach. The speaker 703 can play sounds to drive away the birds, effectively driving away the birds.

[0032] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a set of reflective strips 8 are uniformly fixedly connected to the outer peripheral sidewall of the vertical rod 2; these reflect the surrounding light, improve the visibility of the tower, and enhance safety.

[0033] like Figure 4 and Figure 6 As shown, in a preferred embodiment, based on the above method, both the base 1 and the vertical rod 2 are designed with an internal hollow structure, and a set of mounting holes are evenly opened at the bottom of the base 1; this not only reduces the overall weight of the tower and lowers material costs, but also facilitates the installation of internal wiring and parts.

[0034] Specifically, in use, the wind-resistant structure of this wind power tower works as follows: when wind force acts on the vertical rod 2, the weight ball 604 will sway due to the wind force. The swaying of the weight ball 604 is transmitted to the connecting block 6011. At the same time, the damping rod 608 and the spring 6010 buffer the weight ball 604, thereby reducing the swaying speed of the weight ball 604. This effectively reduces the impact of wind force on the vertical rod 2 and improves the wind resistance of the tower. Meanwhile, the first steel cable 304 connects the vertical rod 2 to the ground, which can reinforce the vertical rod 2 and further improve the wind resistance of the wind power tower. The strobe light 702 can emit a strong flash, which can visually stimulate and disturb birds, making them dare not approach. The speaker 703 can play sounds to drive away birds, further driving away birds and reducing safety hazards.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
