Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a tilting power-off structure. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It uses wind power to drive the blades to rotate, converting kinetic energy into mechanical energy, which is then converted into electricity by a generator. This device includes a wind turbine, a generator, a directional control tower, a speed limiting mechanism, a wind turbine that captures wind power to drive the shaft to rotate, a speed increasing mechanism that increases the speed to drive the generator to work, and finally generates clean electricity for people to use.

[0003] Traditional wind turbines rely on wind power to rotate blades, which in turn drive the main shaft. The main shaft then drives the rotor inside the generator to produce mechanical energy. The generator converts this mechanical energy into electrical energy through electromagnetic induction. The main drawback of traditional wind turbines is that their performance is severely limited by wind speed variations. They are inefficient in low winds and prone to overload and damage in high winds, resulting in unstable power output, insufficient reliability, frequent maintenance requirements, and high costs. Current wind turbine technologies have incorporated microprocessor control structures, using sensors to monitor wind speed and direction and adjust the blade angle of attack in real time to improve capture efficiency and stabilize power output. However, current designs generally lack an automatic tilting and power-off mechanism. In extreme weather conditions such as strong winds and heavy rains that cause the turbine structure to overturn, this lack will immediately trigger a short circuit in the power transmission path. The arc sparks generated by the short circuit ignite surrounding combustibles, burning equipment cables and subsequently expanding the damage to power infrastructure, causing large-scale property losses. Therefore, a wind turbine with a tilting and power-off mechanism is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1, Figure 3 and Figure 4 A wind turbine with a tilting power-off structure includes a tower 1, which serves as a support structure to lift the nacelle and wind turbine 8 to a high altitude to obtain more stable and powerful wind resources and ensure the stability of the whole structure. A tilting mechanism 3 is provided on the top of the outer wall of the tower 1, and an outer shell 2 is fixedly connected to the top of the outer wall of the tower 1. An anti-vibration mechanism 4 is provided on the inner wall of the outer shell 2.

[0033] The tilting mechanism 3 includes a partition 301, which separates different functional components within the housing 2. The outer wall of the partition 301 is fixedly connected to the inner wall of the housing 2. A main switch 302 is fixedly connected to the outer wall of the partition 301, which receives a mechanical linkage signal to perform a tripping action, urgently cutting off the circuit to prevent short circuit accidents. A mounting plate 303 is fixedly connected to the outer wall of the partition 301, which is used to install a tilt sensor 304. The tilt sensor 304 is fixedly connected to the outer wall of the mounting plate 303, which detects abnormal tilting of the tower 1 in real time and outputs a trigger signal to start the protection program. A safety device is installed at the top of the inner wall of the housing 2. A drive assembly 305 includes a cylinder 3051, which, upon receiving a signal from a sensing component, drives a piston rod to move linearly, thereby displacing a connecting plate. The top of the outer wall of the cylinder 3051 is fixedly connected to the top of the inner wall of the housing 2, and a connecting plate 3052 is fixedly connected to the bottom of the outer wall of the cylinder 3051. This connecting plate 3052 transmits the linear motion of the cylinder 3051 to a spring 3061 structure and converts the displacement into an operating force on the main switch 302. A connecting assembly 306, including a spring 3061, is provided on the front side of the outer wall of the main switch 302. The outer wall of the spring 3061 is fixedly connected to... Connected to the outer wall of the connecting plate 3052, the outer wall of the spring 3061 is fixedly connected to the limiting plate 3062, which converts the tension of the spring 3061 into a pulling torque on the connecting plate 3052, forcibly triggering the main switch 302 to act. The outer wall of the main switch 302 is provided with a switch assembly 307, which includes a connector 3071, which is fixed to the end of the spring 3061 and follows the movement trajectory of the cylinder 3051, continuously transmitting mechanical displacement to the limiting structure. The outer wall of the connector 3071 is fixedly connected to the outer wall of the limiting plate 3062, and the outer wall of the main switch 302 is rotatably connected. There is a lever 3072, and the main switch 302 is model CJ20-3150A. When the tilt sensor 304 detects that the tower 1 is tilted, the cylinder 3051 is activated to drive the connecting plate 3052 to move. During the movement, the spring 3061 follows the movement trajectory of the connecting piece 3071 to extend and rebound, so that when the relative position of the connecting plate 3052 and the connecting piece 3071 changes, the connection characteristics of the two are still maintained. Thus, the limit plate 3062 exerts a pulling force on the connecting pieces 3071 and 3052, which drives the main switch 302 to open and close, realize the power cut-off, and avoid short circuit of the power structure.

[0034] Specifically, the tilting mechanism 3 includes a partition 301, which physically separates different functional units inside the outer casing 2. The outer wall of the partition 301 is fixedly connected to the inner wall of the outer casing 2. A main switch 302 is also installed on the outer wall of the partition 301. This component receives mechanical linkage signals to perform a tripping operation, urgently cutting off the power circuit to prevent short circuit faults. A mounting plate 303 is also mounted on the outer wall of the partition 301 to support the fixing of the tilt sensor 304. The tilt sensor 304 is directly fixed to the outer wall of the mounting plate 303, continuously monitoring the attitude deviation of the tower 1 and outputting an error when abnormality occurs. A trigger signal activates the protection program. A drive assembly 305, comprising a cylinder 3051, is positioned on the top of the inner wall of the outer casing 2. The cylinder 3051 receives a sensor signal and drives a piston rod to linearly displace, pulling the connecting plate 3052 to move. The top outer wall of the cylinder 3051 is fixed to the top inner wall of the outer casing 2, and the bottom outer wall of the cylinder 3051 is rigidly connected to the connecting plate 3052. The linear motion of the cylinder 3051 is transmitted to the elastic structure, simultaneously converting the displacement into an operating torque on the main switch 302. A connecting assembly 306 and a spring 3 are arranged on the front outer wall of the main switch 302. One end of 061 is fixed to the outer wall of the connecting plate 3052, and the other end is connected to the limiting plate 3062. The limiting plate 3062 converts the tension of the spring 3061 into a pulling torque on the connecting plate 3052, forcibly triggering the actuator of the main switch 302. A switch assembly 307 is provided on the outer wall of the main switch 302. The connecting piece 3071 is fixed to the end of the spring 3061 and follows the displacement path of the cylinder 3051 to ensure that the mechanical motion is continuously transmitted to the limiting structure. The outer wall of the connecting piece 3071 is fixedly connected to the outer wall of the limiting plate 3062. The outer wall of the main switch 302 also... Rotating the assembly lever 3072, the main switch 302 is model CJ20-3150A. When the tilt sensor 304 detects that the tilt of the tower 1 exceeds the limit, the cylinder 3051 is activated to pull the connecting plate 3052 to move. During the displacement, the spring 3061 extends and retracts according to the trajectory of the connecting piece 3071, maintaining the physical connection between the connecting plate 3052 and the connecting piece 3071 when their relative positions change. Then, the limit plate 3062 applies a pulling force to the connecting piece 3071, driving the main switch 302 to complete the opening operation, realizing the rapid power outage protection of the power structure.

[0035] Reference Figure 1 , Figure 2 and Figure 3The anti-vibration mechanism 4 includes a fixed plate 401, which is used to fix the motor 402 to improve its operating stability. The bottom of the outer wall of the fixed plate 401 is fixedly connected to the bottom of the inner wall of the outer shell 2. The motor 402 is fixedly connected to the bottom of the inner wall of the outer shell 2, which converts electrical energy into mechanical energy and drives the rotating shaft 404 to rotate, providing initial kinetic energy for the anti-vibration mechanism 4. The outer wall of the motor 402 is fixedly connected to a fixing member 403. The output end of the motor 402 is connected to the rotating shaft 404, which transmits the torque and rotational motion output by the motor 402, supports the eccentric block 406 and bears the vibration load, ensuring efficient power transmission. The top of the outer wall of the rotating shaft 404 is fixedly connected to a universal joint 405, which allows the connected components to still smoothly transmit torque when the included angle of the axis changes, avoiding power interruption. The anti-vibration mechanism 4 also includes an eccentric block 406, which acts as an excitation generator. It converts the centrifugal force generated during rotation into periodic vibration force, driving the equipment to generate the required vibration trajectory. The bottom of the outer wall of the eccentric block 406 is fixedly connected to the top of the outer wall of the universal joint 405.

[0036] Specifically, the anti-vibration mechanism 4 includes a fixed plate 401, which provides an installation base for the motor 402 and improves operational stability. The bottom outer wall of the fixed plate 401 is fixed to the bottom inner wall of the outer shell 2. The motor 402 is installed on the bottom inner wall of the outer shell 2, converting electrical energy into mechanical energy to drive the rotating shaft 404 to rotate, providing initial driving force for the structure. The outer wall of the motor 402 is fitted with a fixing part 403 to reinforce positioning. The output end of the motor 402 is connected to the rotating shaft 404, which transmits the output torque and rotational motion of the motor 402, supports the eccentric block 406, and bears the vibration load, ensuring power transmission efficiency. A universal joint 405 is installed on the top outer wall of the rotating shaft 404 to maintain stable torque transmission under the condition of axis angle change, preventing power transmission interruption. The anti-vibration mechanism 4 is also equipped with an eccentric block 406, which serves as an excitation source to generate periodic vibration force through rotational centrifugal force, driving the equipment to form a preset vibration trajectory. The bottom outer wall of the eccentric block 406 is fixed to the top outer wall of the universal joint 405.

[0037] Reference Figure 1 , Figure 2 and Figure 5The outer wall of the outer shell 2 is fixedly connected to the top of the cabin shell 7, which serves as a sealed protective cover to protect the key equipment inside the cabin from the corrosion of the harsh environment and maintain the stability of the internal temperature and humidity. The inner wall of the cabin shell 7 is fixedly connected to the gear set 5, which converts the low-speed, high-torque mechanical energy captured by the wind turbine 8 into high-speed, low-torque kinetic energy through multi-stage speed increase to meet the speed requirements of the generator 402 for efficient power generation. The front side of the outer wall of the gear set 5 is rotatably connected to the main shaft 6, which serves as the core transmission component. It directly receives the mechanical energy generated by the rotation of the wind turbine 8 and transmits it to the gearbox or the direct-drive generator 402. At the same time, it bears wind load, gravity and other multiple complex loads. The front end of the main shaft 6 is fixedly connected to the wind turbine 8, which captures wind energy through a special aerodynamic shape and converts wind power into rotational mechanical energy to drive the main shaft 6 to rotate. Its design directly affects the energy conversion efficiency.

[0038] Specifically, a hull 7 is installed on the top outer wall of the outer shell 2 as a sealed protective cover to isolate it from the harsh external environment, protect the internal core equipment for safe operation, and maintain constant temperature and humidity conditions. A gear set 5 is fixed on the inner wall of the hull 7, which converts the low-speed, high-torque mechanical energy captured by the wind turbine 8 into high-speed, low-torque kinetic energy through multi-stage speed increase, matching the high-efficiency power generation speed requirements of the generator 402. The front outer wall of the gear set 5 is rotatably connected to the main shaft 6, which directly carries the rotational mechanical energy of the wind turbine 8 and transmits power to the gear set 5 or the direct-drive generator 402. The wind turbine 8 is fixed at the front end of the main shaft 6, which captures wind energy by means of its aerodynamic shape and converts the wind energy into rotational mechanical energy to drive the main shaft 6 to rotate.

[0039] Working principle: First, with the help of tilt sensor 304 and power-off structure, when tilt sensor 304 detects that tower 1 is tilting, it activates cylinder 3051 to push connecting plate 3052 to move. During the displacement, spring 3061 extends and retracts along the movement trajectory of connecting piece 3071, directly driving main switch 302 to perform opening and closing action, realizing rapid power cut-off, preventing structural short circuits from causing fires or equipment damage, ensuring property safety and operational continuity, improving overall safety redundancy, reducing costs and improving response efficiency.

[0040] Furthermore, the anti-vibration mechanism 4 converts electrical energy into mechanical power through the motor 402 to drive the rotating shaft 404 to rotate. The fixed plate 401 stabilizes the working state of the motor 402. The rotating shaft 404 supports the eccentric block 406 and transmits high-transmission-rate torque. The universal joint 405 adapts to the axis offset to ensure uninterrupted power transmission. The centrifugal force of the rotating eccentric block 406 generates regular vibration force. The structure works together to generate an anti-phase vibration path, neutralizes the vibration amplitude of the main body, enhances the stability of the equipment, and reduces the risk of fatigue wear.
