[0024] In the description of this utility model, it should be understood that the terms "top", "bottom", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Please see Figures 1 to 4 This utility model provides a safety early warning device for high-altitude operations on power distribution towers, including a fixed box 1 and a pipe clamp 2. The fixed box 1 is equipped with a control device 6. The front side of the fixed box 1 is equipped with a long-distance confirmation mechanism 3 and a short-distance confirmation mechanism. The top of the fixed box 1 is equipped with an audible and visual alarm mechanism 5. The long-distance confirmation mechanism 3, the short-distance confirmation mechanism, and the audible and visual alarm mechanism 5 are electrically connected to the control device 6. One end of the pipe clamp 2 is detachably connected to the rear side of the fixed box 1, and the other end of the pipe clamp 2 is used to realize the detachable connection between the fixed box 1 and the mounting pipe.

[0026] This application discloses a safety early warning device for high-altitude operations on power distribution towers. By setting up a long-distance confirmation mechanism 3 and a short-distance confirmation mechanism, complementary monitoring is formed, which can realize real-time multi-dimensional monitoring of the behavior of construction personnel to cover the detection of dangerous behaviors at different distances and dimensions. By cooperating with the audible and visual alarm mechanism 5, it can promptly remind on-site personnel and management personnel, shorten the response time, and greatly improve the safety of high-altitude operations. In addition, the detachable connection structure of the pipe clamp 2 can realize the quick installation and removal of the fixing box 1 to adapt to towers with different pipe diameters, avoiding the limitations of traditional barrier nets that require welding or bolt fixing.

[0027] In this embodiment, the control device 6 can be an embedded microcontroller, such as the STM32 series, the Arduino ATmega series, or the ESP32 module, to realize the acquisition and processing of sensor data.

[0028] Further, please refer to Figure 1 and Figure 2 The remote confirmation mechanism 3 includes a fixing plate 31, the two ends of which are bolted to the front side of the fixing box 1. An ultrasonic transmitter 32 and an ultrasonic receiver 33 are provided on the front side of the fixing plate 31. The ultrasonic transmitter 32 and the ultrasonic receiver 33 are electrically connected to the control device 6.

[0029] In this embodiment, ultrasonic ranging, as an existing technology, has been widely used in various fields. This technology is based on the propagation speed of ultrasonic waves in the air and the principle of reflection after encountering obstacles. By calculating the time difference between emitting ultrasonic waves and receiving the reflected waves, the distance to the target object is determined. In the long-distance confirmation mechanism 3, the fixing plate 31 plays a key supporting and connecting role. The two ends of the fixing plate 31 are tightly connected to the front side of the fixing box 1 by bolts, ensuring the stability and reliability of the entire mechanism. On the front side of the fixing plate 31, an ultrasonic transmitter 32 and an ultrasonic receiver 33, which are electrically connected to the control device 6, are respectively set to realize the transmission and reception of ultrasonic signals, thereby realizing the accurate measurement of the distance to the target object. Specifically, when it is necessary to measure the distance, the control device 6 sends a signal to the ultrasonic transmitter 32 to emit ultrasonic waves. The ultrasonic waves propagate in the air, are reflected back after encountering the target object, and are received by the ultrasonic receiver 33. The control device 6 calculates the propagation distance of the ultrasonic waves in the air based on the emission and reception time of the ultrasonic waves, and then obtains the distance to the target object.

[0030] Further, please refer to Figure 1 and Figure 2 The top of the fixing plate 31 is provided with a terminal block 34, and the front side of the fixing box 1 is provided with a wiring protection block 11. A wiring groove is provided in the wiring protection block 11. The ultrasonic transmitter 32 and the ultrasonic receiver 33 are electrically connected to the control device 6 through the terminal block 34 and the wiring groove.

[0031] In this embodiment, the terminal block 34 is integrally formed with the fixing plate 31, and the wiring protection block 11 is integrally formed with the fixing box 1. The terminal block 34 on the fixing plate 31 and the wiring protection block 11 on the front side of the fixing box 1, as well as the wiring groove in the wiring protection block 11, provide a convenient channel for the connection between the ultrasonic transmitter 32 and the ultrasonic receiver 33 and the control device 6. At the same time, it ensures the stability and safety of the connection, and effectively protects the wiring part from interference and damage from the external environment, thereby improving the reliability and service life of the remote confirmation mechanism 3 during operation.

[0032] Further, please refer to Figure 1 and Figure 3 The sound and light alarm mechanism 5 includes a base plate 51 and a lampshade 52. The two ends of the base plate 51 are respectively bolted to the top of the fixing box 1. The lampshade 52 is fixed to the top of the base plate 51. A buzzer and an alarm indicator light are provided inside the lampshade 52. The buzzer and the alarm indicator light are respectively electrically connected to the control device 6.

[0033] In this embodiment, the sound and light alarm mechanism 5, which is composed of the base plate 51 and the lampshade 52, realizes the integrated design of alarm function. The base plate 51 is connected to the top of the fixing box 1 by bolts, which ensures the stable installation of the sound and light alarm mechanism 5 and improves the stability and reliability of the overall structure of the safety warning device. The buzzer and alarm indicator light installed in the lampshade 52 can emit sound and light signals at the same time when abnormal approach behavior occurs, realizing a dual warning of potential danger. The sound and light combined alarm method is more intuitive and easier to attract the attention of relevant personnel, thereby improving the alarm effect.

[0034] Further, please refer to Figure 1 The proximity confirmation mechanism includes a camera device 41, an infrared sensor 42, and a dual-frequency turbine sensor, which are electrically connected to the control device 6. The camera device 41 and the infrared sensor 42 are respectively disposed on the front side of the fixed box 1. The dual-frequency turbine sensor is disposed inside the connector. One end of the connector is fixedly connected to the bottom of the fixed box 1, and the front end face of the connector is on the same plane as the front end face of the fixed box 1.

[0035] In this embodiment, the infrared sensor 42 is used to detect thermal radiation from living organisms at 35-40℃ to screen for the presence of personnel or living organisms in high-altitude work environments. It can employ a 16×12 pixel infrared array, model MLX90640, to monitor heat source distribution. The dual-frequency turbine sensor is used to detect the approach of metal objects and can distinguish between iron and aluminum materials to prevent metal tools from accidentally touching dangerous areas. The dual-frequency turbine sensor can be model PT2G-SM5.3. The dual-frequency turbine sensor is calibrated by high-frequency coil impedance and low-frequency Q value, and can analyze metal materials by combining phase angle. The camera device 41 is used to perform target classification, such as identifying the target as personnel, metal tools, animals, or unknowns, which can help determine the target type and behavioral characteristics. The camera device 41 uses a wide-angle camera, model OV5640, in conjunction with a YOLOv5s model trained by existing methods to achieve dynamic visual recognition.

[0036] In this embodiment, the STM32L051C8T6 main control chip enables collaborative control functions including data fusion, dynamic control, and real-time communication. First, by jointly determining the infrared and ultrasonic data, the system can accurately identify the distance and type of the target and trigger corresponding graded responses. Second, when the camera malfunctions, it can dynamically switch to the eddy current sensor enhancement mode to maintain basic early warning functions. Finally, the near-range confirmation module and the far-range confirmation module interact with the main control chip included in the control device 6 via the SPI / IIC protocol, ensuring dynamic adjustment and real-time communication under low power consumption.

[0037] In this embodiment, a long-range confirmation module is used to detect objects at medium to long distances, while a short-range confirmation module is used to identify the type / behavior of objects at close range. When the ultrasonic sensor detects an object approaching at medium distance, the camera is activated to classify the target, ensuring accurate identification of potential threats or targets. When the infrared sensor 42 and the ultrasonic receiver 33 simultaneously detect personnel moving beyond limits, or when the dual-frequency turbine sensor detects metal intrusion, an audible and visual alarm is triggered, enabling a rapid and effective early warning response. The cooperation between the long-range and medium-range confirmation modules not only improves the accuracy and reliability of detection but also greatly enhances the safety of high-altitude operations.

[0038] Further, please refer to Figure 1 The connector includes a connecting box 43 and a connecting rod 44. The dual-frequency turbine sensor is disposed inside the connecting box 43. The front end face of the connecting box 43 is on the same plane as the front end face of the fixing box 1. One end of the connecting rod 44 is fixedly connected to the rear side of the connecting box 43, and the other end of the connecting rod 44 is fixedly connected to the bottom of the fixing box 1.

[0039] In this embodiment, the connecting box 43 and the connecting rod 44 are integrally formed; through the design of the connecting box 43 and the connecting rod 44, a stable connection between the dual-frequency turbine sensor and the fixed box 1 is achieved, so that the dual-frequency turbine sensor can better resist external forces and vibrations during installation and use, thereby improving the accuracy and reliability of measurement.

[0040] Further, please refer to Figure 1 and Figure 4 The rear side of the fixing box 1 is provided with a first fixing post 12, the inner wall of the first fixing post 12 is provided with an internal thread, one end of the pipe clamp 2 is provided with a second fixing post 25, the outer wall of the second fixing post 25 is provided with an external thread, and the internal thread is threadedly connected to the external thread.

[0041] In this embodiment, the first fixing post 12 is integrally formed with the fixing box 1, and the second fixing post 25 is integrally formed with the pipe clamp 2; the internal thread of the inner wall of the first fixing post 12 is precisely matched with the external thread of the outer wall of the second fixing post 25. Through the threaded connection, the pipe clamp 2 is firmly fixed on the fixing box 1, and can remain stable even under vibration or external force.

[0042] Further, please refer to Figure 4 The pipe clamp 2 includes a first pipe clamp 21 and a second pipe clamp 22. One end of the first pipe clamp 21 is rotatably connected to one end of the second pipe clamp 22, and the other end of the first pipe clamp 21 is detachably connected to the other end of the second pipe clamp 22.

[0043] In this embodiment, the pipe clamp 2 is composed of a first pipe clamp 21 and a second pipe clamp 22. One end of the first pipe clamp 21 and one end of the second pipe clamp 22 are connected by a rotating design, which allows the pipe clamp 2 to flexibly adjust its angle to adapt to the needs of pipes of different sizes or shapes. This not only improves the applicability of the pipe clamp 2, but also greatly simplifies the installation process and reduces installation time and labor intensity.

[0044] Further, please refer to Figure 4 The inner wall of the first pipe clamp 21 is provided with a first friction layer 23, and the inner wall of the second pipe clamp 22 is provided with a second friction layer 24.

[0045] In this embodiment, both the first friction layer 23 and the second friction layer 24 are rubber layers. The first friction layer 23 is bonded to the inner wall of the first pipe clamp 21, and the second friction layer 24 is bonded to the inner wall of the second pipe clamp 22. By setting the friction layers, the friction between the pipe clamp 2 and the pipe, i.e. the safety pipe, is significantly increased, which effectively prevents the pipe from sliding during the fixing process and further ensures the stable fixing of the pipe.

[0046] Further, please refer to Figure 4 The first pipe clamp 21 has a first connecting plate at the other end, and the second pipe clamp 22 has a second connecting plate at the other end. The first connecting plate has a first connecting hole 26, and the second connecting plate has a second connecting hole 27. The first connecting hole 26 and the second connecting hole 27 are bolted together.

[0047] In this embodiment, the first connecting plate is integrally formed with the first pipe clamp 21, and the second connecting plate is integrally formed with the second pipe clamp 22. The first connecting hole 26 on the first connecting plate and the second connecting hole 27 on the second connecting plate are tightly connected by bolts. This not only ensures the firm fixation between the first pipe clamp 21 and the second pipe clamp 22, but also makes the entire pipe clamp 2 system more convenient to disassemble and maintain, greatly improving the maintenance efficiency and service life of the system.
