Technical Field
[0001] This application relates to the detection of electric field fans, specifically an electric field fan operation reliability monitoring device. Background Technology
[0002] "Wind turbine" is usually an abbreviation for "wind turbine in a wind farm," referring to wind turbine generator sets used in wind power farms (referred to as "wind farms"). It is the core equipment for converting wind energy into electrical energy. It captures wind energy through blades, drives the rotor (including the hub and blades) to rotate, and then drives the generator to produce electricity through the transmission system. It is a key device for wind farms to achieve clean energy production. Wind turbine monitoring technology refers to a comprehensive technical system that uses various sensing, data transmission, analysis, and diagnostic methods to monitor the key components, operating status, and environmental parameters of wind turbine generator sets (referred to as "wind turbines") in real time or periodically. This system assesses the health status of the equipment, provides early warning of potential faults, and optimizes operating efficiency. Its core objectives are to reduce the failure rate of wind turbines, extend their service life, and improve power generation stability. It is the core technical support for the operation and maintenance management of wind farms.
[0003] The main shaft of the existing electric field fan is prone to high temperature during long-term operation, which can lead to overload. Traditional manual inspection is difficult to monitor the main shaft temperature in real time, so high temperature anomalies cannot be detected in time, which can damage the equipment. Utility Model Content
[0004] In view of the above-mentioned related technologies, the purpose of this application is to provide an electric field wind turbine operation reliability monitoring device, which solves the problem that traditional manual inspection is difficult to achieve real-time monitoring of the main shaft temperature, so that high temperature anomalies cannot be detected in time, thus causing equipment damage.
[0005] The electric field wind turbine operation reliability monitoring device provided in this application adopts the following technical solution: it includes a fixed shell and a mounting shell. A main shaft is fixedly connected to the middle of the mounting shell, and the main shaft extends through to the outside of the fixed shell and is rotatably connected thereto. A fixed frame is rotatably connected to the outer wall of the main shaft, and the fixed frame is fixedly connected to the inside of the fixed shell. A temperature detection sensor is fixedly connected to the top of the fixed frame, and an alarm is fixedly connected to the top of the temperature detection sensor. The alarm is placed on the top of the fixed shell, and two flashing lights are fixedly connected to one side of the alarm.
[0006] By adopting the above technical solution, through the setting of alarm, fixed frame, temperature detection sensor, and flashing light, when the outside wind blows over the blades during use, the blades rotate under the action of the external wind force, thus driving the main shaft between the fixed shell and the mounting shell to rotate synchronously. Under long-term rotation, the high-speed rotation of the main shaft will generate mechanical friction and energy loss, and heat will gradually accumulate and rise during operation. If the temperature continues to rise to the threshold, it may cause failures such as main shaft overload and accelerated bearing wear. Therefore, when the main shaft is rotating, the heat will be transferred to the fixed frame connected to it through heat conduction. The fixed frame is in direct contact with the detection end of the temperature detection sensor, so that the sensor can monitor the temperature change of the main shaft in real time. At the same time, when the temperature detection sensor detects that the temperature is too high, it will trigger the alarm to emit a sharp alarm sound and simultaneously turn on the flashing light to flash continuously. When the temperature drops, it will trigger the automatic shutdown of the flashing light and the alarm to sound. This achieves a large warning range and a relatively direct and effective effect, allowing the staff to understand the purpose of the electric field fan being too high by observing the flashing light from a distance.
[0007] Preferably, a fan is fixedly connected to one side of the temperature detection sensor, wherein the bottom of the fan has multiple ventilation slots facing the fixed frame, and fan blades are fixedly connected to the output end of the fan.
[0008] By adopting the above technical solution, the cooling of the spindle is accelerated, and the operation of the fan is turned off in conjunction with the temperature reduction, thus ensuring cooling efficiency and avoiding ineffective energy consumption, achieving energy-saving operation.
[0009] Preferably, the outer wall of the main shaft is rotatably connected to multiple columns, and the outer walls of the multiple columns are fixedly connected to toothed rings.
[0010] By adopting the above technical solution, after the telescopic rod extends, the motor starts synchronously, driving the gear to rotate, so that the gear meshes with the gear ring.
[0011] Preferably, each of the toothed rings has a brush blade fixedly connected to its top, and the brush blades are in contact with the column rod.
[0012] By adopting the above technical solution, during the rotation of the gear ring, the brush blades on its inner side will continuously wipe the outer wall of the fixed column simultaneously, thereby removing dust and debris that seeps into and adheres from the connection between the fixed column and the mounting shell, and preventing the accumulation of pollutants from affecting the rotational flexibility of the fixed column.
[0013] Preferably, each of the multiple columns is fixedly connected to a fixing column at its top end, wherein the fixing column extends through to the outside of the mounting shell, and each of the multiple fixing columns is fixedly connected to a blade at its top end, and multiple fixing boxes are fixedly connected to the outer wall of the mounting shell.
[0014] By adopting the above technical solution, the electric telescopic pole can be installed and fixed.
[0015] Preferably, each of the plurality of fixed boxes has an electric telescopic rod fixedly connected to its inner wall, and each of the plurality of electric telescopic rods has a fixed block fixedly connected to its output end.
[0016] By adopting the above technical solution, multiple electric telescopic rods in fixed boxes are activated: when the electric telescopic rods extend, the motor is driven to move horizontally through the fixed block.
[0017] Preferably, a motor is fixedly mounted on one end of each of the plurality of fixed blocks, and gears are fixedly connected to the rotor output shafts of the plurality of motors.
[0018] By adopting the above technical solution, when the gear rotates, it meshes with the gear ring.
[0019] Preferably, the plurality of gears are respectively located on the same horizontal plane and mesh with each other.
[0020] The purpose of adopting the above technical solution is to ensure the long-term stable operation of the blade angle adjustment mechanism.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] This electric field fan reliability monitoring device, through the setup of an alarm, a mounting bracket, a temperature sensor, and a flashing light, works as follows: During operation, when external wind blows over the blades, the blades rotate under the force of the wind, which in turn drives the main shaft between the mounting and mounting housings to rotate synchronously. Over long-term operation, the high-speed rotation of the main shaft generates mechanical friction and energy loss, gradually accumulating heat and causing it to heat up. If the temperature continues to rise to a threshold, it may cause overload of the main shaft 2, accelerated bearing wear, and other malfunctions. Therefore, during the rotation of the main shaft, heat is transferred to the connected mounting bracket via thermal conduction. The mounting bracket directly contacts the detection end of the temperature sensor, allowing the sensor to monitor the temperature changes of the main shaft 2 in real time. Simultaneously, when the temperature sensor detects an excessively high temperature, it triggers the alarm to emit a sharp alarm sound and simultaneously activates the flashing light, which flashes continuously. When the temperature decreases, the flashing light and alarm are deactivated, achieving a wide warning range and a direct and effective result. This allows personnel to easily understand the purpose of the electric field fan's internal temperature being too high, even from a distance, by observing the flashing light.
[0023] This electric field fan operation reliability monitoring device, through the arrangement of a fixed shell, a fan, and fan blades, can drive the fan to run when the temperature sensor detects that the main shaft temperature is too high during use. This causes the fan blades to rotate and blow the generated air force onto the outer wall of the fixed frame, thereby accelerating the cooling of the main shaft. When the temperature drops, the fan will shut down in conjunction with the device. This ensures cooling efficiency and avoids ineffective energy consumption, achieving the goal of energy-saving operation.
[0024] This electric wind turbine operation reliability monitoring device, through the arrangement of gear rings, gears, brush blades, columns, fixed columns, and blades, allows operators to activate multiple electric telescopic rods in fixed boxes according to real-time wind direction. When the electric telescopic rods extend, the motor moves horizontally via the fixed block. After the telescopic rods are extended, the motor starts synchronously, driving the gears to rotate. The gears mesh with the gear rings, causing the gear rings and connected columns to rotate. This, in turn, drives the blades to complete angle torsion via the fixed columns, ensuring that the blades maintain the optimal wind-receiving posture in wind farms with different wind directions, thus improving power generation efficiency. At the same time, during the rotation of the gear rings, the brush blades on their inner side continuously wipe the outer wall of the fixed columns, removing dust and debris that seeps into and adheres to the connection between the fixed columns and the mounting housing. This prevents the accumulation of pollutants from affecting the rotational flexibility of the fixed columns and ensures the long-term stable operation of the blade angle adjustment mechanism.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0033] Example 1: A power field wind turbine operation reliability monitoring device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The system includes a fixed housing 1 and a mounting housing 19. A main shaft 2 is fixedly connected to the middle of the mounting housing 19, extending through and rotatably connected to the fixed housing 1. A fixing frame 7 is rotatably connected to the outer wall of the main shaft 2, and the fixing frame 7 is fixedly connected to the inside of the fixed housing 1. A temperature detection sensor 8 is fixedly connected to the top of the fixing frame 7, and an alarm 6 is fixedly connected to the top of the temperature detection sensor 8. The alarm 6 is located on the top of the fixed housing 1, and two flashing lights 17 are fixedly connected to one side of the alarm 6. Through the arrangement of the alarm 6, fixing frame 7, temperature detection sensor 8, and flashing lights 17, when the outside wind blows over the blades 5 during use, the blades 5 rotate under the action of the outside wind force, thus driving the main shaft 2 between the fixed housing 1 and the mounting housing 19 to rotate synchronously. Under long-term rotational operation, the main shaft 2... High-speed rotation generates mechanical friction and energy loss, gradually accumulating heat and raising the temperature. If the temperature continues to rise to a threshold, it may cause overload of the spindle 2, accelerated bearing wear, and other malfunctions. Therefore, when the spindle 2 is rotating, the heat is transferred to the fixed frame 7 connected to it through heat conduction. The fixed frame 7 is in direct contact with the detection end of the temperature sensor 8, enabling the sensor to monitor the temperature change of the spindle 2 in real time. At the same time, when the temperature sensor 8 detects that the temperature is too high, it triggers the alarm 6 to emit a sharp alarm sound and simultaneously turns on the flashing light 17 to flash continuously. When the temperature drops, it triggers the flashing light 17 to turn off and the alarm 6 to sound, achieving a wide warning range and a direct and effective effect. This allows staff to understand the purpose of the electric field fan being too hot by observing the flashing light 17 from a distance.
[0034] Example 2: A power field wind turbine operation reliability monitoring device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The device includes a fan 9 fixedly connected to one side of a temperature sensor 8. The bottom of the fan 9 has multiple ventilation slots facing the mounting frame 7. The output end of the fan 9 is fixedly connected to a fan blade 18. Through the arrangement of the mounting housing 1, the fan 9, and the fan blade 18, the fan 9 can be driven to run when the temperature sensor 8 detects that the spindle 2 is too hot during use. This causes the fan blade 18 to rotate and blow the generated air onto the outer wall of the mounting frame 7, thereby accelerating the cooling of the spindle 2. When the temperature drops, the fan 9 is turned off in conjunction with the device. This ensures cooling efficiency and avoids ineffective energy consumption, achieving the goal of energy-saving operation.
[0035] Example 3: A power field wind turbine operation reliability monitoring device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The system includes a main shaft 2 with multiple rods 3 rotatably connected to its outer wall. Each rod 3 has a gear ring 10 fixedly connected to its outer wall. Each gear ring 10 has a brush blade 16 fixedly connected to its top, with the brush blades 16 adhering to the rods 3. Each rod 3 has a fixed post 4 fixedly connected to its top, extending through to the outside of the mounting housing 19. Each fixed post 4 has a blade 5 fixedly connected to its top. The mounting housing 1 has multiple fixed boxes 11 fixedly connected to its outer wall. Each fixed box 11 has an electric telescopic rod 12 fixedly connected to its inner wall. Each electric telescopic rod 12 has a fixed block 13 fixedly connected to its output end. Each fixed block 13 has a motor 14 fixedly mounted at one end. Each motor 14 has a gear 15 fixedly connected to its rotor output shaft. Each gear 15 is on the same horizontal plane and meshes with each gear ring 10. The system utilizes the gear rings 10, gears 15, brush blades 16, and rods 3. The installation of the fixed column 4 and blades 5 allows operators to activate multiple electric telescopic rods 12 within the fixed boxes 11 based on real-time wind direction. When the electric telescopic rod 12 extends, it drives the motor 14 to move horizontally via the fixed block 13. After the telescopic rod extends, the motor 14 starts synchronously, driving the gear 15 to rotate. This causes the gear 15 to mesh with the gear ring 10, rotating the gear ring 10 and the connected column 3. Consequently, the fixed column 4 drives the blades 5 to complete the angle twist, ensuring that the blades maintain the optimal wind-receiving posture in wind fields with different wind directions, thus improving power generation efficiency. Simultaneously, during the rotation of the gear ring 10, the brush blades 16 on its inner side continuously wipe the outer wall of the fixed column 4, removing dust and debris that seeps into and adheres from the connection between the fixed column 4 and the mounting shell 19. This prevents the accumulation of pollutants from affecting the rotational flexibility of the fixed column 4 and ensures the long-term stable operation of the blade angle adjustment mechanism.
[0036] The implementation principle of this application embodiment is as follows: First, when the electric field fan is running, when the outside wind blows over the blades 5, the blades 5 rotate under the action of the outside wind force, thus driving the main shaft 2 between the fixed shell 1 and the mounting shell 19 to rotate synchronously. Under long-term rotational operation, the high-speed rotation of the main shaft 2 will generate mechanical friction and energy loss, and heat will gradually accumulate and rise during operation. If the temperature continues to rise to a threshold, it may cause failures such as overload of the main shaft 2 and accelerated bearing wear. Therefore, when the main shaft 2 is rotating, the heat will be transferred to the fixed frame 7 connected to it through heat conduction. The frame 7 directly contacts the detection end of the temperature sensor 8, enabling the sensor to monitor the temperature changes of the main shaft 2 in real time. Simultaneously, when the temperature sensor 8 detects an excessively high temperature, it triggers the alarm 6 to emit a sharp alarm sound and simultaneously activates the flashing light 17, which flashes continuously. When the temperature decreases, the flashing light 17 stops flashing, and the alarm 6 sounds again, thus alerting staff that the electric fan is operating at too high a temperature. This provides a wide-ranging and direct warning, allowing staff to easily observe the flashing light 17 from a distance and promptly understand that the internal temperature of the electric fan is too high. After the temperature sensor 8 detects that the main shaft 2 is too hot, it drives the fan 9 to run, causing the fan blades 18 to rotate and blow the generated air onto the outer wall of the mounting frame 7, thereby accelerating the cooling of the main shaft 2. When the temperature drops, the fan 9 is shut down in conjunction with the sensor, thus ensuring cooling efficiency and avoiding ineffective energy consumption, achieving energy-saving operation. To adapt to changes in wind direction, operators can activate multiple electric telescopic rods 12 in the mounting boxes 11 according to the real-time wind direction: when the electric telescopic rod 12 extends, it drives the motor 14 to move horizontally through the fixing block 13; after the telescopic rod extends, the motor 14 moves horizontally. The first step starts, driving the gear 15 to rotate, causing the gear 15 to mesh with the gear ring 10, driving the gear ring 10 and the connected column 3 to rotate, which in turn drives the blade 5 to complete the angle torsion through the fixed column 4, ensuring that it always maintains the best wind-receiving posture in wind fields with different wind directions, improving power generation efficiency. At the same time, during the rotation of the gear ring 10, the brush blades 16 on its inner side will continuously wipe the outer wall of the fixed column 4, which can effectively remove dust and debris that seeps into and adheres from the connection between the fixed column 4 and the mounting shell 19, avoiding the accumulation of pollutants that affect the rotational flexibility of the fixed column 4, and ensuring the long-term stable operation of the blade angle adjustment mechanism.
